EMCAP belongs to the group of medicines called "cytostatic medicines", which stop the growth of cancer cells. EMCAP contains capecitabine, which itself is not a cytostatic medicine. Only after being absorbed by the body is it changed into an active anti-cancer medicine (more in tumour tissue than in normal tissue).
EMCAP is used in the treatment of colon, rectal, gastric, or breast cancers.
Furthermore, EMCAP is used to prevent new occurrence of colon cancer after complete removal of the tumour by surgery.
EMCAP may be used either alone or in combination with other medicines.
Do not take EMCAP
If you are allergic to capecitabine or any of the other ingredients of this medicine (listed in
section 6). You must inform your doctor if you know that you have an allergy or over reaction
to this medicine,
If you previously have had severe reactions to fluoropyrimidine therapy (a group of anticancer medicines such as fluorouracil),
If you are pregnant or breast-feeding,
If you have severely low levels of white cells or platelets in the blood (leucopenia, neutropenia or thrombocytopenia),
If you have severe liver or kidney problems,
If you know that you do not have any activity of the enzyme dihydropyrimidine dehydrogenase (DPD)
If you are being treated now or have been treated in the last 4 weeks with brivudine, sorivudine or similar classes of substance as part of herpes zoster (chickenpox or shingles) therapy.
Warnings and precautions
Talk to your doctor or pharmacist before taking EMCAP
If you know that you have a partial deficiency in the activity of the enzyme dihydropyrimidine
dehydrogenase (DPD)
If you have liver or kidney diseases
If you have or had heart problems (for example an irregular heartbeat or pains to the chest jaw
and back brought on by physical effort and due to problems with the blood flow to the heart)
If you have brain diseases (for example. cancer that has spread to the brain, or nerve damage
(neuropathy)
If you have calcium imbalances (seen in blood tests)
If you have diabetes
If you cannot keep food or water in your body because of severe nausea and vomiting
If you have diarrhoea
If you are or become dehydrated
If you have imbalances of ions in your blood (electrolyte imbalances, seen in tests)
If you have a history of eye problems as you may need extra monitoring of your eyes
- If you have a severe skin reaction.
DPD deficiency: DPD deficiency is a rare condition present at birth that is not usually associated with health problems unless you receive certain medicines. If you have an unrecognised DPD deficiency and take EMCAP, you are at an increased risk of acute early-onset of severe forms of the side effects listed under section 4 Possible side effects. Contact your doctor immediately if you are concerned about any of the side effects or if you notice any additional side effects not listed in the leaflet (see section 4 Possible side effects).
Children and adolescents
EMCAP is not indicated in children and adolescents. Do not give EMCAP to children and adolescents.
Other medicines and EMCAP
Before starting treatment, tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This is extremely important, as taking more than one medicine at the same time can strengthen or weaken the effect of the medicines.
You must not take brivudine (an anti-viral medicines for treatment of shingles or chickenpox) at the same time as capecitabine treatment (including during any rest periods when you are not taking any capecitabine tablets).
If you have taken brivudine you must wait for at least 4 weeks after stopping brivudine before starting to take capecitabine. See also section “Do not take EMCAP”.
Also, you need to be particularly careful if you are taking any of the following:
gout medicines (allopurinol),
blood-thinning medicines (coumarin, warfarin),
medicines for seizures or tremors (phenytoin),
interferon alpha,
radiotherapy and certain medicines used to treat cancer (folinic acid, oxaliplatin, bevacizumab,
cisplatin, irinotecan),
medicines used to treat folic acid deficiency.
EMCAP with food and drink
You should take EMCAP no later than 30 minutes after meals.
Pregnancy, breast-feeding and pregnancy
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. You must not take EMCAP if you are pregnant or think you might be.
You must not breast-feed if you are taking EMCAP and for 2 weeks after the last dose.If you are a male patient and your female partner could become pregnant, you should use effective contraception during treatment with EMCAP and for 3 months after the last dose.
Driving and using machines
EMCAP may make you feel dizzy, nauseous or tired. It is therefore possible that EMCAP could affect your ability to drive a car or operate machines.
EMCAP contains anhydrous lactose
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
EMCAP should only be prescribed by a doctor experienced in the use of anticancer medicines.
Your doctor will prescribe a dose and treatment regimen that is right for you. The dose of EMCAP is based on your body surface area. This is calculated from your height and weight. The usual dose for adults is 1250 mg/m2 of body surface area taken two times daily (morning and evening). Two examples are provided here: A person whose body weight is 64 kg and height is 1.64 m has a body surface area of 1.7 m2 and should take 4 tablets of 500 mg and 1 tablet of 150 mg two times daily. A person whose body weight is 80 kg and height is 1.80 m has a body surface area of 2.00 m2 and should take 5 tablets of 500 mg two times daily.
Your doctor will tell you what dose you need to take, when to take it and for how long you need to take it.
Your doctor may want you to take a combination of 150 mg and 500 mg tablets for each dose.
Take the tablets morning and evening as prescribed by your doctor.
Take the tablets within 30 minutes after the end of a meal (breakfast and dinner) and swallow whole with water. Do not crush or cut tablets. If you cannot swallow EMCAP tablets whole, tell your healthcare provider.
It is important that you take all your medicine as prescribed by your doctor.
EMCAP tablets are usually taken for 14 days followed by a 7 day rest period (when no tablets are taken). This 21 day period is one treatment cycle.
In combination with other medicines the usual dose for adults may be less than 1250 mg/m2 of body surface area, and you may need to take the tablets over a different time period (e.g. every day, with no rest period).If you take more EMCAP than you should
If you take more EMCAP than you should, contact your doctor as soon as possible before taking the next dose.
You might get the following side effects if you take a lot more capecitabine than you should: feeling or being sick, diarrhoea, inflammation or ulceration of the gut or mouth, pain or bleeding from the intestine or stomach, or bone marrow depression (reduction in certain kinds of blood cells). Tell your doctor immediately if you experience any of these symptoms.If you forget to take EMCAP
Do not take the missed dose at all. Do not take a double dose to make up for a forgotten dose. Instead, continue your regular dosing schedule and check with your doctor.
- If you stop taking EMCAP
There are no side effects caused by stopping treatment with capecitabine. In case you are using coumarin anticoagulants (containing e.g. phenprocoumon), stopping capecitabine might require that your doctor adjusts your anticoagulant dose.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them. STOP taking EMCAP immediately and contact your doctor if any of these symptoms occur:
Diarrhoea: if you have an increase of 4 or more bowel movements compared to your normal
bowel movements each day or any diarrhoea at night.
Vomiting: if you vomit more than once in a 24-hour time period.
Nausea: if you lose your appetite, and the amount of food you eat each day is much less than
usual.
Stomatitis: if you have pain, redness, swelling or sores in your mouth and/or throat.
Hand-and-foot skin-reaction: if you have pain, swelling, redness or tingling of hands and/or
feet
Fever: if you have a temperature of 38°C or greater.
Infection: if you experience signs of infection caused by bacteria or virus, or other organisms.
Chest pain: if you experience pain localised to the centre of the chest, especially if it occurs
during exercise.
Steven-Johnson syndrome: if you experience painful red or purplish rash that spreads and
blisters and/or other lesions begin to appear in the mucous membrane (e.g. mouth and lips), in particular if you had before light sensitivity, infections of the respiratory system (e.g. bronchitis) and/or fever.
DPD Deficiency: if you have a known DPD deficiency, you are at an increased risk of acute early-onset of toxicity and severe, life-threatening, or fatal adverse reactions caused by EMCAP (e.g. stomatitis, mucosal inflammation, diarrhoea, neutropenia, and neurotoxicity).
If caught early, these side effects usually improve within 2 to3 days after treatment discontinuation. If these side effects continue, however, contact your doctor immediately. Your doctor may instruct you to restart treatment at a lower dose.
Hand and foot skin-reaction can lead to loss of fingerprint, which could impact your identification by fingerprint scan.
In addition to the above, when EMCAP is used alone, very common side effects, which may affect more than 1 in 10 people are:abdominal pain
rash, dry or itchy skin
tiredness
loss of appetite (anorexia)
These side effects can become severe; therefore, it is important that you always contact your doctor immediately when you start to experience a side effect.

ينتمي إمكاب إلى مجموعة الأدوية التي تسمى "الأدوية المثبطة للخلايا"، التي توقف نمو الخلايا السرطانية. يحتوي إمكاب على كابيسيتابين، وهو بحد ذاته ليس دواء لتثبيط الخلايا. فقط بعد أن يمتصه الجسم، فإنه يتحول إلى دواء فعال مضاد للسرطان (أكثر فاعلية في أنسجة الورم من الأنسجة الطبيعية).
يستخدم إمكاب في علاج سرطانات القولون, المستقيم, المعدة, أو الثدي.
علاوة على ذلك، يستخدم إمكاب لمنع حدوث سرطان القولون من جديد بعد إزالة الورم كاملاً عن طريق الجراحة.
يمكن استخدام إمكاب إما بمفرده أو بالمشاركة مع الأدوية الأخرى.
لا تأخذ إمكاب:
• إذا كان لديك حساسية تجاه كابيسيتابين أو أي من المكونات الأخرى لهذا الدواء (المدرجة في القسم 6). يجب عليك إبلاغ طبيبك إذا كنت تعرف أن لديك حساسية أو رد فعل زائد لهذا الدواء،
• إذا حدث معك سابقاً ردود فعل شديدة أثناء المعالجة بالفلوروبايريدين (مجموعة من أدوية مضادة للسرطان مثل فلورويوراسيل)،
• إذا كنتِ حاملاً أو مرضعةً
• إذا كان لديك مستويات منخفضة للغاية من الخلايا البيضاء أو الصفيحات في الدم (قلة الكريات البيضاء، قلة العدلات, أو قلة الصفيحات)،
• إذا كان لديك مشاكل حادة في الكبد أو الكلى،
• إذا كنت تعلم أنه ليس عندك أي نشاط لأنزيم ديهايدروبيريميدين دِهايدروجيناز (DPD),
• إذا كنت تُعالَج حالياً أو أنك قد عولجت في الأربعة أسابيع الماضية بمادة بريڤودين, سوريڤودين أو فئات مماثلة لهذه المادة كجزء من علاج داء المنطقة (جدري الماء أو القوباء المنطقية),
المحاذير والإحتياطات
تحدث إلى طبيبك أو الصيدلي قبل تناول إمكاب:
• إذا كنت تعرف أن لديك نقصاً جزئياً في نشاط إنزيم ديهايدروبيريميدين دِهايدروجيناز (DPD),
• إذا كان لديك أمراض في الكبد أو الكلى,
• إذا كان لديك حالياً أو سابقاً مشاكل في القلب (مثل: عدم انتظام ضربات القلب أو آلام في فك الصدر والظهر بسبب الجهد البدني وبسبب مشاكل في تدفق الدم إلى القلب),
• إذا كان لديك أمراض في الدماغ (مثل، سرطان منتشر إلى المخ، أو تلف أعصاب (اعتلال عصبي),
• إذا كان لديك اختلال في الكالسيوم (تظهر في اختبارات الدم),
• إذا كان لديك مرض السكري,
• إذا كنت لا تستطيع الاحتفاظ بالطعام أو الماء في جسمك بسبب الغثيان الشديد والقيء,
• إذا كان لديك إسهال,
• إذا كان لديك جفاف أو أصبح عندك جفاف,
• إذا كان لديك اختلال في أيونات دمك (اختلال توازن بالكهارب، تظهر في الفحوصات),
• إذا كان لديك تاريخ سابق لمشاكل عينية فقد تحتاج إلى مراقبة خاصة لعينيك,
• إذا كان لديك رد فعل جلدي شديد.
نقص الـ DPD: نقص الديهايدروبيريميدين دِهايدروجيناز DPD هو حالة نادرة موجودة عند الولادة ولا ترتبط عادة بالمشاكل الصحية ما لم تتلقى أدوية معينة. إذا كان لديك نقصاً غير معروفٍ للـ DPD وأخذت إمكاب، فأنت في خطر متزايد للإصابة المبكرة بأشكال حادة من التأثيرات الجانبية المدرجة في القسم 4 "تأثيرات جانبية محتملة",
اتصل بطبيبك على الفور إذا كنت تشعر بقلق إزاء أي من التأثيرات الجانبية أو إذا لاحظت أية تأثيرات جانبية إضافية غير مدرجة في النشرة (انظر القسم 4 "تأثيرات جانبية محتملة").
الأطفال والمراهقين
لا يوصف إمكاب للأطفال والمراهقين. لا تُعطي إمكاب للأطفال والمراهقين.
الأدوية الأخرى وإمكاب
قبل بدء العلاج، أخبر طبيبك أو الصيدلي إذا كنت تتناول، أو قد أخذت مؤخراً أو قد تأخذ أية أدوية أخرى. وهذا مهم للغاية، حيث إن تناول أكثر من دواء واحد بنفس الوقت يمكن أن يُقوّي أو يُضعِف تأثير الأدوية,
يجب ألا تأخذ بريڤودين (أدوية مضادة للفيروسات لعلاج القوباء المنطقية أو جدري الماء) بنفس الوقت مع علاج مثل كابيسيتابين (بما في ذلك خلال أية فترات راحة عندما لا تتناول أية أقراص من كابيسيتابين).
إذا كنت قد أخذت بريڤودين يجب عليك الانتظار مدة 4 أسابيع على الأقل بعد إيقاف بريڤودين قبل البدء بتناول كابيسيتابين. انظر أيضاً القسم "لا تأخذ إمكاب".
أيضاً، يجب أن تحرص بشكل خاص إذا كنت تأخذ أيّاً مما يلي:
• أدوية النقرس (الوبورينول)،
• أدوية مميعة للدم (كومارين، وارفارين)،
• أدوية النوبات أو الهزات (فينيتوئين)،
• إنترفيرون ألفا،
• علاج إشعاعي وبعض الأدوية المستخدمة لعلاج السرطان (حمض فولينيك, أوكساليبلاتين، بيڤاسيزوماب، سيسبلاتين، إرينوتيكان)،
• أدوية مستخدمة لعلاج نقص حمض الفوليك.
إمكاب مع الطعام والشراب
يجب أن تأخذ إمكاب بموعد لا يتجاوز 30 دقيقة بعد وجبات الطعام.
الحمل, الرضاعة الطبيعية والحمل
إذا كنتِ حاملاً أو مرضعةً، تظنين أنكِ قد تكوني حاملاً أو تخططين لإنجاب طفل، اسألي طبيبك أو الصيدلي للحصول على المشورة قبل تناول هذا الدواء. يجب أن لا تأخذي إمكاب إذا كنتِ حاملا أو تظنين أنكِ كذلك.
يجب أن لا تُرضعي إذا كنتِ تتناولين إمكاب ولمدة أسبوعين بعد آخر جرعة.
إذا كنتَ مريضاً ذَكَراً ويمكن أن تصبح شريكتك الأنثى حاملاً، يجب عليك استخدام موانع حمل فعالة أثناء العلاج بدواء إمكاب ولمدة 3 أشهر بعد آخر جرعة.
القيادة واستخدام الآلات
قد يجعلك إمكاب تشعر بالدوار أو الغثيان أو التعب. فمن الممكن عندئذ أن يؤثر إمكاب على قدرتك في قيادة السيارة أو تشغيل الآلات.
يحتوي إمكاب على اللاكتوز اللامائي
إذا أخبرك طبيبك بأنك لا تتحمل بعض السكريات، اتصل بطبيبك قبل تناول هذا الدواء.
تناول هذا الدواء دائماً تماماً كما أخبرك طبيبك أو الصيدلي. تحقق مع طبيبك أو الصيدلي إذا كنت غير متأكد.
يجب أن يوصف إمكاب فقط من قبل طبيب ذو خبرة باستخدام الأدوية المضادة للسرطان.
سيصف طبيبك الجرعة والعلاج المناسب لك. تعتمد جرعة إمكاب على مساحة سطح جسمك. ويُحسب ذلك من طولك ووزنك. الجرعة المعتادة للبالغين هي 1250 ملغ/م2 من مساحة سطح الجسم تؤخذ مرتين يومياً (صباحاً ومساءً).
فيما يلي مثالان:
- الشخص الذي يبلغ وزن جسمه 64 كغ وطوله 1,64 متراً لديه مساحة سطح جسم 1,7 م2 ويجب أن يأخذ 4 أقراص من عيار 500 ملغ وقرص واحد من عيار 150 ملغ مرتان يومياً.
- الشخص الذي يبلغ وزن جسمه 80 كغ وطوله 1,80 متراً لديه مساحة سطح جسم 2,00م2 ويجب أن يأخذ 5 أقراص من عيار 500 ملغ مرتان يومياً.
سيخبرك طبيبك بالجرعة التي تحتاجها، وموعد تناولها، ولأي مدة أنت بحاجة لأخذها.
قد يرتأي طبيبك أن تأخذ خليطاً من أقراص 150 ملغ و 500 ملغ لكل جرعة.
• تناول أقراصك في الصباح والمساء كما وصفها طبيبك.
• خذ الأقراص في غضون 30 دقيقة بعد نهاية الوجبة (الإفطار والعشاء) وابلعها بالكامل مع الماء. لا تسحق أو تقطع الأقراص. إذا لم تستطع بلع أقراص إمكاب بكاملها، أخبر مقدم الرعاية الصحية الخاص بك.
• من المهم أن تتناول دواءك كاملاً كما وصفه لك طبيبك.
تؤخذ أقراص إمكاب عادةً لمدة 14 يوماً تليها فترة راحة لمدة 7 أيام (حيث لا تأخذ أقراص). هذه الفترة لمدة 21 يوماً هي دورة علاج واحدة.
بالمشاركة مع الأدوية الأخرى، قد تقل الجرعة المعتادة للبالغين عن 1250 ملغ/م2 من مساحة سطح الجسم، وقد تحتاج إلى تناول الأقراص على مدى فترة زمنية مختلفة (مثلاً: كل يوم، بدون فترة راحة).
إذا أخذت إمكاب أكثر مما يجب
إذا أخذت إمكاب أكثر مما يجب، اتصل بطبيبك بأسرع ما يمكن قبل تناول الجرعة التالية.
قد تتعرض للتأثيرات الجانبية التالية إذا أخذت كابيسيتابين أكثر بكثير مما يجب: شعور بأنك مريض, إسهال, التهاب أو تقرح أمعاء أو فم, ألم أو نزيف من الأمعاء أو المعدة, أو انخفاض في النخاع العظمي (نقص في أنواع معينة من خلايا الدم). أخبر طبيبك فوراً إذا عانيت من أي من هذه الأعراض.
إذا نسيت أن تأخذ إمكاب
لا تأخذ الجرعة الفائتة إطلاقاً. لا تأخذ جرعة مضاعفة لتعويض جرعة منسية.
بدلاً من ذلك، تابع جدولك الزمني للجرعات بانتظام واستشر طبيبك.
إذا توقفت عن تناول إمكاب
لا يوجد أية تأثيرات جانبية ناجمة عن وقف المعالجة بمادة كابيسيتابين. وفي حالة استخدامك مضادات التخثر الكومارينية (الحاوية مثلاً على فينبروكومون)، قد يتطلب إيقاف كابيسيتابين أن يقوم طبيبك بتعديل جرعة مضاد التخثر.
إذا كان لديك أية أسئلة أخرى حول استخدام هذا الدواء، اسأل طبيبك أو الصيدلي.
مثل جميع الأدوية ، يمكن أن يسبب هذا الدواء تأثيرات جانبية، ولو أنها لا تحصل لدى كل شخص.
توقَّف عن تناول إمكاب على الفور واتصل بطبيبك في حالة حدوث أي من هذه الأعراض:
• إسهال: إذا كنت تعاني من زيادة 4 مرات أو أكثر في حركات الأمعاء مقارنة بحركات أمعائك الطبيعية كل يوم أو أي إسهال في الليل.
• قيء: إذا تقيأت أكثر من مرة واحدة خلال فترة 24 ساعة.
• غثيان: إذا فقدت شهيتك، وإذا كانت كمية الطعام التي تتناولها كل يوم أقل بكثير من المعتاد.
• التهاب فم: إذا حصل عندك ألم, احمرار, تورم أو تقرحات في فمك و/أو حلقك.
• رد فعل في جلد اليد والقدم: إذا حصل عندك ألم, أو تورم, احمرار أو وخز في اليدين و/أو القدمين.
• حمى: إذا حصل عندك درجة حرارة 38° مئوية أو أكثر.
• عدوى: إذا كنت تعاني من علامات عدوى سببها البكتيريا أو الفيروسات, أو كائنات حية أخرى.
• ألم في الصدر: إذا كنت تعاني من ألم متوضع في مركز الصدر، خاصةً إذا كان يحدث أثناء التمرين.
• متلازمة ستيفن - جونسون: إذا كنت تعاني من طفح جلدي مؤلم أحمر أو أرجواني منتشر وبثور و/أو آفات أخرى بدأت تظهر في الغشاء المخاطي (مثل الفم والشفاه)، وبخاصة إذا كنت قد تعرضت من قبل لحساسية الضوء، التهابات الجهاز التنفسي (مثل التهاب الشعب الهوائية) و/أو الحمى.
• نقص DPD: إذا كان لديك نقصاً معروفاً في DPD, فأنت أكثر عرضة لخطر السمية المبكرة والتفاعلات الضارة الشديدة التي تهدد الحياة أو المميتة الناجمة عن إمكاب (مثل التهاب الفم، التهاب الغشاء المخاطي، إسهال، قلة العِدلات, والسمية العصبية).
إذا اكتُشفت باكراً, فإن هذه التأثيرات عادةً ما تتحسَّن في غضون يومين إلى ثلاثة أيام بعد وقف العلاج.
إذا استمرت هذه التأثيرات الجانبية، بكل الأحوال, اتصل بطبيبك على الفور. فقد يوصيك طبيبك بإعادة بدء المعالجة بجرعة أقل.
يمكن أن يؤدي رد فعل الجلد في اليد والقدم لفقدان بصمة الأصابع، مما قد يؤثر على هويتك في ماسحة بصمات الأصابع.

Posology adjustments during treatment General
Toxicity due to capecitabine administration may be managed by symptomatic treatment and/or modification of the dose (treatment interruption or dose reduction). Once the dose has been reduced, it should not be increased ata later time. For those toxicities considered by the treating physician to be unlikely to become serious or life-threatening, e.g. alopecia, altered taste, nail changes, treatment can be continued at the same dose without reduction or interruption.
Patients taking capecitabine should be informed of the need to interrupt treatment immediately if moderate or severe toxicity occurs. Doses of capecitabine omitted for toxicity are not replaced. The following are the recommended dose modifications for toxicity:

*According to the National Cancer Institute of Canada Clinical Trial Group (NCIC CTG) Common Toxicity Criteria(version 1) or the Common Terminology Criteria for Adverse Events (CTCAE) of the Cancer Therapy Evaluation Program, US National Cancer Institute, version 4.0. For hand-foot syndrome and hyperbilirubinemia, see section 4.4.
Haematology
Patients with baseline neutrophil counts of <1.5x109/L and/or thrombocyte counts of
<100x109/L should not be treated with capecitabine. If unscheduled laboratory assessments during a treatment cycle show that the neutrophil count drops below 1.0 x 109/L or that the platelet count drops below 75 x 109/L, treatment with capecitabine should be interrupted.
Dose modifications for toxicity when capecitabine is used as a 3 weekly cycle in combination with other medicinal products
Dose modifications for toxicity when capecitabine is used as a 3 weekly cycle in combination with othermedicinal products should be made according to table 3 above for capecitabine and according to the appropriate summary of product characteristics for the other medicinal product(s).
At the beginning of a treatment cycle, if a treatment delay is indicated for either capecitabine or the other medicinal product(s), then administration of all therapy should be delayed until the requirements for restarting all medicinal products are met.
During a treatment cycle for those toxicities considered by the treating physician not to be related to capecitabine, capecitabine should be continued and the dose of the other medicinal product should be adjusted according to the appropriate Prescribing Information.
If the other medicinal product(s) have to be discontinued permanently, capecitabine treatment can be resumed when the requirements for restarting capecitabine are met.
This advice is applicable to all indications and to all special populations.
Dose modifications for toxicity when capecitabine is used continuously in combination with other medicinal products
Dose modifications for toxicity when capecitabine is used continuously in combination with other medicinal products should be made according to table 3 above for capecitabine and according to the appropriate summary of product characteristics for the other medicinal product(s).
Posology adjustments for special populations:
Hepatic impairment
Insufficient safety and efficacy data are available in patients with hepatic impairment to provide a doseadjustment recommendation. No information is available on hepatic impairment due to cirrhosis or hepatitis.
Renal impairment
Capecitabine is contraindicated in patients with severe renal impairment (creatinine clearance below 30 ml/min [Cockcroft and Gault] at baseline). The incidence of grade 3 or 4 adverse reactions in patients with moderate renal impairment (creatinine clearance 30-50 ml/min at baseline) is increased compared to the overall population. In patients with moderate renal impairment at baseline, a dose reduction to 75% for a starting dose of 1250 mg/m2 is recommended. In patients with moderate renal impairment at baseline, no dose reduction is required for a starting dose of 1000 mg/m2. In patients with mild renal impairment (creatinine clearance 51-80 ml/min at baseline) no adjustment of the starting dose is recommended.
Careful monitoring and prompt treatment interruption is recommended if the patient develops a grade 2, 3 or 4adverse event during treatment and subsequent dose adjustment as outlined in table 3 above. If the calculatedcreatinine clearance decreases during treatment to a value below 30 ml/min, Capecitabine should be discontinued.These dose adjustment recommendations for renal impairment apply both to monotherapy and combination use (see also section “Elderly” below).
Elderly
During capecitabine monotherapy, no adjustment of the starting dose is needed. However, grade 3 or 4 treatment-related adverse reactions were more frequent in patients ≥60 years of age compared to younger patients.
When capecitabine was used in combination with other medicinal products, elderly patients (≥65 years)experienced more grade 3 and grade 4 adverse drug reactions, including those leading to discontinuation, compared to younger patients. Careful monitoring of patients ≥60 years of age is advisable.
- In combination with docetaxel: an increased incidence of grade 3 or 4 treatment-related adverse reactions andtreatment-related serious adverse reactions were observed in patients 60 years of age or more (see section 5.1). For patients 60 years of age or more, a starting dose reduction of capecitabine to 75% (950 mg/m2 twice daily) is recommended. If no toxicity is observed in patients ≥60 years of age treated with reduced capecitabine starting dose in combination with docetaxel, the dose of capecitabine may be cautiously escalated to 1250 mg/m2 twice daily.
Paediatric population
There is no relevant use of capecitabine in the paediatric population in the indications colon, colorectal, gastric and breast cancer.
Method of administration
EMCAP should be swallowed whole with water within 30 minutes after a meal. EMCAP should not be crushed or cut.
Dose limiting toxicities
Dose limiting toxicities include diarrhoea, abdominal pain, nausea, stomatitis and hand-foot syndrome (hand-foot skin reaction, palmar-plantar erythrodysesthesia). Most adverse reactions are reversible and do not require permanent discontinuation of therapy, although doses may need to be withheld or reduced.
Diarrhoea.
Patients with severe diarrhoea should be carefully monitored and given fluid and electrolyte replacement if they become dehydrated. Standard antidiarrhoeal treatments (e.g. loperamide) may be used. NCIC CTC grade 2 diarrhoea is defined as an increase of 4 to 6 stools/day or nocturnal stools, grade 3 diarrhoea as an increase of 7 to 9 stools/day or incontinence and malabsorption. Grade 4 diarrhoea is an increase of ≥10stools/day or grossly bloody diarrhoea or the need for parenteral support. Dose reduction should be applied as necessary (see section 4.2).
Dehydration.
Dehydration should be prevented or corrected at the onset. Patients with anorexia, asthenia, nausea, vomiting or diarrhoea may rapidly become dehydrated. Dehydration may cause acute renal failure, especially in patients with pre-existing compromised renal function or when capecitabine is given concomitantly with known nephrotoxic medicinal products. Acute renal failure secondary to dehydration might be potentially fatal. If grade 2 (or higher) dehydration occurs, capecitabine treatment should be immediately interrupted and thedehydration corrected. Treatment should not be restarted until the patient is rehydrated and any precipitatingcauses have been corrected or controlled. Dose modifications applied should be applied for the precipitating adverse event as necessary (see section 4.2).
Hand-foot syndrome
(also known as hand-foot skin reaction or palmar-plantar erythrodysesthesia or chemotherapy induced acral erythema). Grade 1 hand-foot syndrome is defined as numbness, dysesthesia/paresthesia, tingling, painless swelling or erythema of the hands and/or feet and/or discomfort which does not disrupt the patient's normal activities. Grade 2 hand-foot syndrome is painful erythema and swelling ofthe hands and/or feet and/or discomfort affecting the patient's activities of daily living. Grade 3 hand-foot syndrome is moist desquamation, ulceration, blistering and severe pain of the hands and/or feet and/or severediscomfort that causes the patient to be unable to work or perform activities of daily living. Persistent or severe hand-foot syndrome (Grade 2 and above) can eventually lead to loss of fingerprints which could impact patient identification.
If grade 2 or 3 hand-foot syndrome occurs, administration of capecitabine should be interrupted until the event resolves or decreases in intensity to grade 1. Following grade 3 hand-foot syndrome, subsequent doses of capecitabine should be decreased. When capecitabine and cisplatin are used in combination, the use of vitamin B6 (pyridoxine) is not advised for symptomatic or secondary prophylactic treatment of hand–foot syndrome, because of published reports that it may decrease the efficacy of cisplatin. There is some evidence that dexpanthenol is effective for hand-foot syndrome prophylaxis in patients treated with Capecitabine.
Cardiotoxicity.
Cardiotoxicity has been associated with fluoropyrimidine therapy, including myocardial infarction, angina, dysrhythmias, cardiogenic shock, sudden death and electrocardiographic changes (including very rare cases of QT prolongation). These adverse reactions may be more common in patients with a prior history of coronary artery disease. Cardiac arrhythmias (including ventricular fibrillation, torsade de pointes, and bradycardia), angina pectoris, myocardial infarction, heart failure and cardiomyopathy have been reported in patients receiving capecitabine. Caution must be exercised in patients with history of significant cardiac disease, arrhythmias and angina pectoris (see section 4.8).
Hypo- or hypercalcaemia.
Hypo- or hypercalcaemia has been reported during capecitabine treatment. Caution must be exercised in patients with pre-existing hypo- or hypercalcaemia (see section 4.8).
Central or peripheral nervous system disease.
Caution must be exercised in patients with central or peripheral nervous system disease, e.g. brain metastasis or neuropathy (see section 4.8).
Diabetes mellitus or electrolyte disturbances.
Caution must be exercised in patients with diabetes mellitus or electrolyte disturbances, as these may be aggravated during capecitabine treatment.
Coumarin-derivative anticoagulation.
In an interaction study with single-dose warfarin administration, therewas a significant increase in the mean AUC (+57%) of S-warfarin. These results suggest an interaction, probably due to an inhibition of the cytochrome P450 2C9 isoenzyme system by capecitabine. Patients receivingconcomitant capecitabine and oral coumarin-derivative anticoagulant therapy should have their anticoagulant response (INR or prothrombin time) monitored closely and the anticoagulant dose adjusted accordingly (see section 4.5).
Brivudine.
Brivudine must not be administered concomitantly with capecitabine. Fatal cases have been reported following this drug interaction. There must be at least a 4-week waiting period between end of treatment with brivudine and start of capecitabine therapy. Treatment with brivudine can be started 24 hours after the last dose of capecitabine (see section 4.3 and 4.5). In the event of accidental administration of brivudine to patients being treated with capecitabine, effective measures should be taken to reduce the toxicity of capecitabine. Immediateadmission to hospital is recommended. All measures should be initiated to prevent systemic infections and dehydration.
Hepatic impairment.
In the absence of safety and efficacy data in patients with hepatic impairment,Capecitabine use should be carefully monitored in patients with mild to moderate liver dysfunction, regardless ofthe presence or absence of liver metastasis. Administration of capecitabine should be interrupted if treatment-related elevations in bilirubin of >3.0 x ULN or treatment-related elevations in hepatic aminotransferases (ALT,AST) of >2.5 x ULN occur. Treatment with capecitabine monotherapy may be resumed when bilirubin decreasesto ≤3.0 x ULN or hepatic aminotransferases decrease to ≤ 2.5 x ULN.
Renal impairment.
The incidence of grade 3 or 4 adverse reactions in patients with moderate renal impairment (creatinine clearance 30-50 ml/min) is increased compared to the overall population (see sections 4.2 and 4.3).
Dihydropyrimidine dehydrogenase (DPD) deficiency:
Rarely, unexpected, severe toxicity (e.g. stomatitis, diarrhoea, mucosal inflammation, neutropenia and neurotoxicity) associated with 5-FU has been attributed to a deficiency of DPD activity.
Patients with low or absent DPD activity, an enzyme involved in fluorouracil degradation, are at increased risk for severe, life-threatening, or fatal adverse reactions caused by fluorouracil. Although DPD deficiency cannot be precisely defined, it is known that patients with certain homozygous or certain compound heterozygous mutations in the DPYD gene locus (e.g. DPYD*2A, c.1679T>G, c.2846A>T and c.1236G>A/HapB3 variants), which can cause complete or near complete absence of DPD enzymatic activity (as determined from laboratory assays), have the highest risk of life-threatening or fatal toxicity and should not be treated with Capecitabine (see section 4.3). No dose has been proven safe for patients with complete absence of DPD activity.
Patients with certain heterozygous DPYD variants (including DPYD*2A, c.1679T>G, c.2846A>T andc.1236G>A/HapB3 variants) have been shown to have increased risk of severe toxicity when treated with capecitabine.
The frequency of the heterozygous DPYD*2A genotype in the DPYD gene in Caucasian patients is around 1%,1.1% for c.2846A>T, 2.6-6.3% for c.1236G>A/HapB3 variants and
0.07 to 0.1% for c.1679T>G. Genotyping for these alleles is recommended to identify patients at increased risk for severe toxicity. Data on the frequency of these DPYD variants in other populations than Caucasian is limited. It cannot be excluded that other rare variants may also be associated with an increased risk of severe toxicity.
For patients with partial DPD deficiency (such as those with heterozygous mutations in the DPYD gene) and where the benefits of Capecitabine are considered to outweigh the risks (taking into account the suitability of an alternative nonfluoropyrimidine chemotherapeutic regimen), these patients must be treated with extreme caution and frequent monitoring with dose adjustment according to toxicity. A reduction of the starting dose in these patients may be considered to avoid serious toxicity. There is insufficient data to recommend a specific dose inpatients with partial DPD activity as measured by specific test. It has been reported that the DPYD*2A,c.1679T>G variants lead to a greater reduction in enzymatic activity than the other variants with a higher risk ofside effects. The consequences of a reduced dose for efficacy are currently uncertain. Therefore, in the absence of serious toxicity the dose could be increased while carefully monitoring the patient.
The patients who are tested negative for the above-mentioned alleles may still have a risk of severe adverse events.
In patients with unrecognised DPD deficiency treated with capecitabine as well as in those patients who testnegative for specific DPYD variations, life-threatening toxicities manifesting as acute overdose may occur (see section 4.9). In the event of grade 2-4 acute toxicity, treatment must be discontinued immediately.
Permanent discontinuation should be considered based on clinical assessment of the onset, duration and severity of the observed toxicities.
Ophthalmologic complications:
Patients should be carefully monitored for ophthalmological
complications such as keratitis and corneal disorders, especially if they have a prior history of eye disorders. Treatment of eye disorders should be initiated as clinically appropriate.
Severe skin reactions:
Capecitabine can induce severe skin reactions such as Stevens-Johnson syndrome andToxic Epidermal Necrolysis. Capecitabine should be permanently discontinued in patients who experience a severe skin reaction during treatment.
As this medicinal product contains anhydrous lactose as an excipient, patients with rare hereditary problems ofgalactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.
EMCAP should not be crushed or cut. In case of exposure of either patient or caregiver to crushed or cut EMCAP tablets adverse drug reactions could occur (see Section 4.8).
Interaction studies have only been performed in adults. Interaction with other medicinal products
Brivudine: a clinically significant interaction between brivudine and fluoropyrimidines (e.g. capecitabine, 5-Fluorouracil, tegafur), resulting from the inhibition of dihydropyrimidine dehydrogenase by brivudine, has been described. This interaction, which leads to increased fluoropyrimidine toxicity, is potentially fatal. Therefore, brivudine must not be administered concomitantly with capecitabine (see section 4.3 and 4.4). There must be at least a 4-week waiting period between end of treatment with brivudine and start of capecitabine therapy. Treatment with brivudine can be started 24 hours after the last dose of capecitabine.
Cytochrome P-450 2C9 substrates: Other than warfarin, no formal interaction studies between capecitabine and other CYP2C9 substrates have been conducted. Care should be exercised when capecitabine is co-administered with 2C9 substrates (e.g., phenytoin). See also interaction with coumarin-derivative anticoagulants below, and section 4.4.
Coumarin-derivative anticoagulants: altered coagulation parameters and/or bleeding have been reported in patients taking capecitabine concomitantly with coumarin-derivative anticoagulants such as warfarin andphenprocoumon. These reactions occurred within several days and up to several months after initiating capecitabine therapy and, in a few cases, within one month after stopping capecitabine. In a clinicalpharmacokinetic interaction study, after a single 20 mg dose of warfarin, capecitabine treatment increased theAUC of S-warfarin by 57% with a 91% increase in INR value. Since metabolism of R-warfarin was not affected, these results indicatethat capecitabine down-regulates isozyme 2C9, but has no effect on isozymes 1A2 and 3A4. Patients taking coumarin-derivative anticoagulants concomitantly with capecitabine should be monitored regularly foralterations in their coagulation parameters (PT or INR) and the anticoagulant dose adjusted accordingly.
Phenytoin: increased phenytoin plasma concentrations resulting in symptoms of phenytoin intoxication in single cases have been reported during concomitant use of capecitabine with phenytoin. Patients taking phenytoin concomitantly with capecitabine should be regularly monitored for increased phenytoin plasma concentrations.
Folinic acid/folic acid: a combination study with capecitabine and folinic acid indicated that folinic acid has no major effect on the pharmacokinetics of capecitabine and its metabolites. However, folinic acid has an effect onthe pharmacodynamics of capecitabine and its toxicity may be enhanced by folinic acid: the maximum tolerated dose (MTD) of capecitabine alone using the intermittent regimen is 3000 mg/m2 per day whereas it is only 2000 mg/m2 per day when capecitabine was combined with folinic acid (30 mg orally bid). The enhanced toxicity may be relevant when switching from 5- FU/LV to a capecitabine regimen. This may also be relevant with folic acid supplementation for folate deficiency due to the similarity between folinic acid and folic acid.
Antacid: the effect of an aluminium hydroxide and magnesium hydroxide-containing antacid on the pharmacokinetics of capecitabine was investigated. There was a small increase in plasma concentrations ofcapecitabine and one metabolite (5'-DFCR); there was no effect on the 3 major metabolites (5'-DFUR, 5-FU and FBAL).
Allopurinol: interactions with allopurinol have been observed for 5-FU; with possible decreased efficacy of 5-FU. Concomitant use of allopurinol with capecitabine should be avoided.
Interferon alpha: the MTD of capecitabine was 2000 mg/m2 per day when combined with interferon alpha-2a (3 MIU/m2 per day) compared to 3000 mg/m2 per day when capecitabine was used alone.
Radiotherapy: the MTD of capecitabine alone using the intermittent regimen is 3000 mg/m2 per day, whereas,when combined with radiotherapy for rectal cancer, the MTD of capecitabine is 2000 mg/m2 per day using either a continuous schedule or given daily Monday through Friday during a 6-week course of radiotherapy.
Oxaliplatin: no clinically significant differences in exposure to capecitabine or its metabolites, free platinum or total platinum occurred when capecitabine was administered in combination with oxaliplatin or in combination with oxaliplatin and bevacizumab.
Bevacizumab: there was no clinically significant effect of bevacizumab on the pharmacokinetic parameters of capecitabine or its metabolites in the presence of oxaliplatin.
Food interaction
In all clinical trials, patients were instructed to administer capecitabine within 30 minutes after a meal. Since current safety and efficacy data are based upon administration with food, it is recommended that capecitabine be administered with food. Administration with food decreases the rate of capecitabine absorption (see section 5.2).
Women of childbearing potential/Contraception in males and females
Women of childbearing potential should be advised to avoid becoming pregnant while receiving treatment with capecitabine. If the patient becomes pregnant while receiving capecitabine, the potential hazard to the foetus must be explained. An effective method of contraception should be used during treatment and for 6 months after the last dose of capecitabine.
Based on genetic toxicity findings, male patients with female partners of reproductive potential should use effective contraception during treatment and for 3 months following the last dose of capecitabine.
Pregnancy
There are no studies in pregnant women using capecitabine; however, it should be assumed that capecitabine may cause foetal harm if administered to pregnant women. In reproductive toxicity studies in animals, capecitabine administration caused embryolethality and teratogenicity. These findings are expected effects of fluoropyrimidine derivatives. Capecitabine is contraindicated during pregnancy.
Breast-feeding
It is not known whether capecitabine is excreted in human breast milk. No studies have been conducted to assess the impact of capecitabine on milk production or its presence in human breast milk. In lactating mice, considerable amounts of capecitabine and its metabolites were found in milk. As the potential for harm to thenursing infant is unknown, breast-feeding should be discontinued while receiving treatment with capecitabine and for 2 weeks after the final dose.
Fertility
There is no data on capecitabine and impact on fertility. The capecitabine pivotal studies included females ofchildbearing potential and males only if they agreed to use an acceptable method of birth control to avoid pregnancy for the duration of the study and for a reasonable period thereafter.
In animal studies effects on fertility were observed (see section 5.3).
Capecitabine has minor or moderate influence on the ability to drive and use machines.
Capecitabine may cause dizziness, fatigue and nausea.
Summary of the safety profile
The overall safety profile of capecitabine is based on data from over 3000 patients treated with capecitabine as monotherapy or capecitabine in combination with different chemotherapy regimens in multiple indications. The safety profiles of capecitabine monotherapy for the metastatic breast cancer, metastatic colorectal cancer and adjuvant colon cancer populations are comparable. See section 5.1 for details of major studies, including studydesigns and major efficacy results.
The most commonly reported and/or clinically relevant treatment-related adverse drug reactions (ADRs) were gastrointestinal disorders (especially diarrhoea, nausea, vomiting, abdominal pain, stomatitis), hand-footsyndrome (palmar-plantar erythrodysesthesia), fatigue, asthenia, anorexia, cardiotoxicity, increased renal dysfunction on those with preexisting compromised renal function, and thrombosis/embolism.
Tabulated list of adverse reactions
ADRs considered by the investigator to be possibly, probably, or remotely related to the administration ofcapecitabine are listed in table 4 for capecitabine given as monotherapy and in table 5 for capecitabine given in combination with different chemotherapy regimens in multiple indications. The following headings are used to rank the ADRs by frequency: very common (≥ 1/10), common (≥ 1/100 to < 1/10), uncommon (≥ 1/1,000 to < 1/100), rare (≥ 1/10,000 to <1/1,000), very rare (< 1/10,000). Within each frequency grouping, ADRs are presented in order of decreasing seriousness.
Capecitabine Monotherapy:
Table 4 lists ADRs associated with the use of capecitabine monotherapy based on a pooled analysis of safetydata from three major studies including over 1900 patients (studies M66001, SO14695, and SO14796). ADRs areadded to the appropriate frequency grouping according to the overall incidence from the pooled analysis.

Capecitabine in combination therapy
Table 5 lists ADRs associated with the use of capecitabine in combination with different chemotherapyregimens in multiple indications based on safety data from over 3000 patients. ADRs are added to theappropriate frequency grouping (Very common or Common) according to the highest incidence seen in any of themajor clinical trials and are only added when they were seen in addition to those seen with capecitabine monotherapy or seen at a higher frequency grouping compared to capecitabine monotherapy (see table 4). Uncommon ADRs reported for capecitabine in combination therapy are consistent with the ADRs reported for capecitabine monotherapy or reported for monotherapy with the combination medicinal product (in literature and/or respective summary of product characteristics).
Some of the ADRs are reactions commonly seen with the combination medicinal product (e.g. peripheral sensory neuropathy with docetaxel or oxaliplatin, hypertension seen with bevacizumab); however an exacerbation by capecitabine therapy cannot be excluded.

Description of selected adverse reactions
Hand-foot syndrome (see section 4.4):
For the capecitabine dose of 1250 mg/m2 twice daily on days 1 to 14 every 3 weeks, a frequency of 53% to 60%of all-grades HFS was observed in capecitabine monotherapy trials (comprising studies in adjuvant therapy in colon cancer, treatment of metastatic colorectal cancer, and treatment of breast cancer) and a frequency of 63% was observed in the capecitabine/docetaxel arm for the treatment of metastatic breast cancer. For the capecitabine dose of 1000 mg/m2 twice daily on days 1 to 14 every 3 weeks, a frequency of 22% to 30% of all-grade HFS was observed in capecitabine combination therapy.
A meta-analysis of 14 clinical trials with data from over 4700 patients treated with capecitabine monotherapy orcapecitabine in combination with different chemotherapy regimens in multiple indications (colon, colorectal,gastric and breast cancer) showed that HFS (all grades) occurred in 2066 (43%) patients after a median time of 239 [95% CI 201, 288] days after starting treatment with capecitabine. In all studies combined, the followingcovariates were statistically significantly associated with an increased risk of developing HFS: increasing capecitabine starting dose (gram), decreasing cumulative capecitabine dose (0.1*kg), increasing relative doseintensity in the first six weeks, increasing duration of study treatment (weeks), increasing age (by 10 year increments), female gender, and good ECOG performance status at baseline (0 versus ≥1).
Diarrhoea (see section 4.4):
Capecitabine can induce the occurrence of diarrhoea, which has been observed in up to 50% of patients.
The results of a meta-analysis of 14 clinical trials with data from over 4700 patients treated with capecitabine showed that in all studies combined, the following covariates were statistically significantly associated with anincreased risk of developing diarrhoea: increasing capecitabine starting dose (gram), increasing duration of studytreatment (weeks), increasing age (by 10 year increments), and female gender. The following covariates were statistically significantly associated with a decreased risk of developing diarrhoea: increasing cumulative capecitabine dose (0.1*kg) and increasing relative dose intensity in the first six weeks.
Cardiotoxicity (see section 4.4):
In addition to the ADRs described in tables 4 and 5, the following ADRs with an incidence of less than 0.1% were associated with the use of capecitabine monotherapy based on a pooled analysis from clinical safety data from 7 clinical trials including 949 patients (2 phase III and
5 phase II clinical trials in metastatic colorectal cancer and metastatic breast cancer): cardiomyopathy, cardiac failure, sudden death, and ventricular extrasystoles.
Encephalopathy:
In addition to the ADRs described in tables 4 and 5 and based on the above pooled analysis from clinical safetydata from 7 clinical trials, encephalopathy was also associated with the use of capecitabine monotherapy with an incidence of less than 0.1%.
Exposure to crushed or cut capecitabine tablets:
In the instance of exposure to crushed or cut capecitabine tablets, the following adverse drug reactions have been reported: eye irritation, eye swelling, skin rash, headache, paresthesia, diarrhea, nausea, gastric irritation, and vomiting.
Special populations
Elderly patients (see section 4.2):
An analysis of safety data in patients ≥60 years of age treated with capecitabine monotherapy and an analysis ofpatients treated with capecitabine plus docetaxel combination therapy showed an increase in the incidence oftreatment- related grade 3 and 4 adverse reactions and treatment-related serious adverse reactions compared topatients <60 years of age.
Patients ≥60 years of age treated with capecitabine plus docetaxel also had more early withdrawals from treatment due to adverse reactions compared to patients <60 years of age.
The results of a meta-analysis of 14 clinical trials with data from over 4700 patients treated with capecitabineshowed that in all studies combined, increasing age (by 10 year increments) was statistically significantly associated with an increased risk of developing HFS and diarrhoea and with a decreased risk of developing neutropenia.
Gender
The results of a meta-analysis of 14 clinical trials with data from over 4700 patients treated with capecitabine showed that in all studies combined, female gender was statistically significantly associated with an increased risk of developing HFS and diarrhoea and with a decreased risk of developing neutropenia.
Patients with renal impairment (see section 4.2, 4.4, and 5.2):
An analysis of safety data in patients treated with capecitabine monotherapy (colorectal cancer) with baselinerenal impairment showed an increase in the incidence of treatment-related grade 3 and 4 adverse reactions compared to patients with normal renal function (36% in patients without renal impairment n=268, vs. 41% in mild n=257 and 54% in moderate n=59, respectively) (see section 5.2). Patients with moderately impaired renal function show an increased rate of dose reduction (44%) vs. 33% and 32% in patients with no or mild renal impairment and an increase in early withdrawals from treatment (21% withdrawals during the first two cycles) vs. 5% and 8% in patients with no or mild renal impairment.

Pharmacotherapeutic group: cytostatic (antimetabolite), ATC code: L01BC06
Capecitabine is a non-cytotoxic fluoropyrimidine carbamate, which functions as an orally administeredprecursor of the cytotoxic moiety 5-fluorouracil (5-FU). Capecitabine is activated via several enzymatic steps (see section 5.2). The enzyme involved in the final conversion to 5-FU, thymidine phosphorylase (ThyPase), is found in tumour tissues, but also in normal tissues, albeit usually at lower levels. In human cancer xenograft models capecitabine demonstrated a synergistic effect in combination with docetaxel, which may be related to the upregulation of thymidine phosphorylase by docetaxel.
There is evidence that the metabolism of 5-FU in the anabolic pathway blocks the methylation reaction of deoxyuridylic acid to thymidylic acid, thereby interfering with the synthesis of deoxyribonucleic acid (DNA). The incorporation of 5-FU also leads to inhibition of RNA and protein synthesis. Since DNA and RNA areessential for cell division and growth, the effect of 5-FU may be to create a thymidine deficiency that provokes unbalanced growth and death of a cell. The effects of DNA and RNA deprivation are most marked on those cells which proliferate more rapidly and which metabolise 5-FU at a more rapid rate.
Colon and colorectal cancer:
Monotherapy with capecitabine in adjuvant colon cancer
Data from one multicentre, randomised, controlled phase III clinical trial in patients with stage III (Dukes' C) colon cancer supports the use of capecitabine for the adjuvant treatment of patients with colon cancer. In this trial, 1987 patients were randomised to treatment with capecitabine (1250 mg/m2 twice daily for 2 weeks followed by a 1- week rest period and given as 3-week cycles for 24 weeks) or 5-FU and leucovorin (Mayo Clinic regimen: 20 mg/m2 leucovorin IV followed by 425 mg/m2 intravenous bolus 5-FU, on days 1 to 5, every 28 days for 24 weeks). Capecitabine wasat least equivalent to IV 5-FU/LV in disease-free survival in per protocol population (hazard ratio 0.92; 95% CI 0.80- 1.06). In the all-randomised population, tests for difference of capecitabine vs 5-FU/LV in disease-free andoverall survival showed hazard ratios of 0.88 (95% CI 0.77 – 1.01; p = 0.068) and 0.86 (95% CI 0.74 – 1.01; p
= 0.060), respectively. The median follow up at the time of the analysis was 6.9 years. In a preplanned multivariate Cox analysis, superiority of capecitabine compared with bolus 5- FU/LV was demonstrated. The following factors were pre-specified in the statistical analysis plan for inclusion in the model: age, time fromsurgery to randomization, gender, CEA levels at baseline, lymph nodes at baseline, and country. In the all-randomised population, capecitabine was shown to be superior to 5FU/LV for disease-free survival (hazard ratio0.849; 95% CI 0.739 - 0.976; p = 0.0212), as well as for overall survival (hazard ratio 0.828; 95% CI
0.705 - 0.971; p = 0.0203).
Combination therapy in adjuvant colon cancer
Data from one multicentre, randomised, controlled phase 3 clinical trial in patients with stage III (Dukes' C) colon cancer supports the use of capecitabine in combination with oxaliplatin (XELOX) for the adjuvant treatment of patients with colon cancer (NO16968 study). In this trial, 944 patients were randomised to 3-week cycles for 24 weeks with capecitabine (1000 mg/m2 twice daily for 2 weeks followed by a 1-week rest period) in combination with oxaliplatin (130 mg/m2 intravenous infusion over 2-hours on day 1 every 3 weeks); 942 patients were randomised to bolus 5-FU and leucovorin. In the primary analysis for DFS in the ITT population, XELOX was shown to be significantly superior to 5-FU/LV (HR=0.80, 95% CI= [0.69; 0.93]; p=0.0045). The 3 year DFS rate was 71% for XELOX versus 67% for 5- FU/LV.
The analysis for the secondary endpoint of RFS supports these results with a HR of 0.78 (95% CI=[0.67; 0.92]; p=0.0024) for XELOX vs. 5-FU/LV. XELOX showed a trend towards superior OS with a HR of 0.87 (95% CI=[0.72; 1.05]; p=0.1486) which translates into a 13% reduction in risk of death. The 5 year OS rate was 78% forXELOX versus 74% for 5-FU/LV. The efficacy data is based on a median observation time of 59 months for OS and 57 months for DFS. The rate of withdrawal due to adverse events was higher in the XELOX combination therapy arm (21%) as compared with that of the 5-FU/LV monotherapy arm (9%) in the ITT population.
Monotherapy with capecitabine in metastatic colorectal cancer
Data from two identically-designed, multicentre, randomised, controlled phase III clinical trials (SO14695;SO14796) support the use of capecitabine for first line treatment of metastatic colorectal cancer. In these trials,603 patients were randomised to treatment with capecitabine (1250 mg/m2 twice daily for 2 weeks followed by a 1-week rest period and given as 3-week cycles). 604 patients were randomised to treatment with 5-FU andleucovorin (Mayo regimen: 20 mg/m2 leucovorin intravenous followed by 425 mg/m2 intravenous bolus 5-FU, on days 1 to 5, every 28 days). The overall objective response rates in the all-randomised population (investigator assessment) were 25.7% (capecitabine) vs. 16.7% (Mayo regimen); p <0.0002. The median time to progression was 140 days (capecitabine) vs. 144 days (Mayo regimen). Median survival was 392 days (capecitabine) vs. 391 days (Mayo regimen). Currently, no comparative data are available on capecitabine monotherapy in colorectal cancer in comparison with first line combination regimens.
Combination therapy in first-line treatment of metastatic colorectal cancer
Data from a multicentre, randomised, controlled phase III clinical study (NO16966) support the use ofcapecitabine in combination with oxaliplatin or in combination with oxaliplatin and bevacizumab for the first-line treatment of metastatic colorectal cancer. The study contained two parts: an initial 2-arm part in which 634 patients were randomised to two different treatment groups, including XELOX or FOLFOX-4, and a subsequent 2x2 factorial part in which 1401 patients were randomised to four different treatment groups, including XELOX plus placebo, FOLFOX-4 plus placebo, XELOX plus bevacizumab, and FOLFOX-4 plus bevacizumab. See table 6 for treatment regimens.
Table 6 Treatment regimens in study NO16966 (mCRC)
| Treatment | Starting Dose | Schedule |
FOLFOX-4 or FOLFOX-4 + Bevacizumab | Oxaliplatin | 85 mg/m2 intravenous 2 hr | Oxaliplatin on Day 1, every 2 weeks Leucovorin on Days 1 and 2, every 2 weeks 5-fluorouracil intravenous bolus/infusion, each on Days 1 and 2, every 2 weeks |
Leucovorin | 200 mg/m2 intravenous 2 hr | ||
5-Fluorouracil | 400 mg/m2 intravenous bolus, followed by 600 mg/ m2 intravenous 22 hr |
| Placebo or Bevacizumab | 5 mg/kg intravenous 30-90 mins | Day 1, prior to FOLFOX-4, every 2 weeks |
XELOX or XELOX + Bevacizumab | Oxaliplatin | 130 mg/m2 intravenous 2 hr | Oxaliplatin on Day 1, every 3 weeks Capecitabine oral twice daily for 2 weeks (followed by 1 week off-treatment) |
Capecitabine | 1000 mg/m2 oral twice daily | ||
Placebo or Bevacizumab | 7.5 mg/kg intravenous 30-90 mins | Day 1, prior to XELOX, every 3 weeks | |
5-Fluorouracil: intravenous bolus injection immediately after leucovorin |
Non-inferiority of the XELOX-containing arms compared with the FOLFOX-4-containing arms in the overall comparison was demonstrated in terms of progression-free survival in the eligible patient population and the intent-to-treat population (see table 7). The results indicate that XELOX is equivalent to FOLFOX-4 in terms of overall survival (see table 7). A comparison of XELOX plus bevacizumab versus FOLFOX-4 plus bevacizumab was a pre- specified exploratory analysis. In this treatment subgroup comparison, XELOX plus bevacizumabwas similar compared to FOLFOX-4 plus bevacizumab in terms of progression- free survival (hazard ratio 1.01; 97.5% CI 0.84 - 1.22). The median follow up at the time of the primary analyses in the intent-to-treat population was 1.5 years; data from analyses following an additional 1 year of follow up are also included in table 7. However, the on- treatment PFS analysis did not confirm the results of the general PFS and OS analysis: the hazard ratio of XELOX versus FOLFOX-4 was 1.24 with 97.5% CI 1.07 - 1.44. Although sensitivity analyses show that differences in regimen schedules and timing of tumor assessments impact the on treatment PFS analysis, a full explanation for this result has not been found.

In a randomised, controlled phase III study (CAIRO), the effect of using capecitabine at a starting dose of 1000mg/m2 for 2 weeks every 3 weeks in combination with irinotecan for the first-line treatment of patients withmetastatic colorectal cancer was studied. 820 Patients were randomised to receive either sequential treatment (n=410) or combination treatment (n=410). Sequential treatment consisted of first line capecitabine (1250 mg/m2twice daily for 14 days), second-line irinotecan (350 mg/m2 on day 1), and third-line combination of capecitabine(1000 mg/m2 twice daily for 14 days) with oxaliplatin (130 mg/m2 on day 1). Combination treatment consisted of first-line capecitabine (1000 mg/m2 twice daily for 14 days) combined with irinotecan (250 mg /m2 on day 1) (XELIRI) and second-line capecitabine (1000 mg/m2 twice daily for 14 days) plus oxaliplatin (130 mg/m2 on day 1). All treatment cycles were administered at intervals of 3 weeks. In first-line treatment the median progression-free survival in the intent-to-treat population was 5.8 months (95%CI 5.1 - 6.2 months) for capecitabine monotherapy and 7.8 months (95%CI 7.0 - 8.3 months; p=0.0002) for XELIRI. However this was associated with an increased incidence of gastrointestinal toxicity and neutropenia during first line treatment with XELIRI (26% and 11% for XELIRI and first line capecitabine respectively).
The XELIRI has been compared with 5-FU + irinotecan (FOLFIRI) in three randomised studies in patients with metastatic colorectal cancer. The XELIRI regimens included capecitabine 1000 mg/m2 twice daily on days 1 to 14 of a three-week cycle combined with irinotecan 250 mg/m2 on day1. In the largest study (BICC-C), patients were randomised to receive either open label FOLFIRI (n=144), bolus 5-FU (mIFL) (n=145) or XELIRI (n=141) and were additionally randomised to receive either double-blind treatment with celecoxib or placebo. Median PFS was 7.6 months for FOLFIRI, 5.9 months for mIFL (p=0.004) for the comparison with FOLFIRI), and 5.8 months for XELIRI (p=0.015). Median OS was 23.1 months for FOLFIRI, 17.6 months for mIFL(p=0.09), and 18.9 months for XELIRI (p=0.27). Patients treated with XELIRI experienced excessive gastrointestinal toxicity compared with FOLFIRI (diarrhoea 48% and 14% for XELIRI and FOLFIRI respectively).
In the EORTC study patients were randomised to receive either open label FOLFIRI (n=41) or XELIRI (n=44) with additional randomisation to either double-blind treatment with celecoxib or placebo. Median PFS and overall survival (OS) times were shorter for XELIRI versus FOLFIRI (PFS 5.9 versus 9.6 months and OS 14.8versus 19.9 months), in addition to which excessive rates of diarrhoea were reported in patients receiving the XELIRI regimen (41% XELIRI, 5.1% FOLFIRI).
In the study published by Skof et al, patients were randomised to receive either FOLFIRI or XELIRI . Overall response rate was 49% in the XELIRI and 48% in the FOLFIRI arm (p=0.76). At the end of treatment, 37% of patients in the XELIRI and 26% of patients in the FOLFIRI arm were without evidence of the disease (p=0.56). Toxcity was similar between treatments with the exception of neutropenia reported more commonly in patientstreated with FOLFIRI.
Montagnani et al used the results from the above three studies to provide an overall analysis of randomized studies comparing FOLFIRI and XELIRI treatment regimens in the treatment of mCRC. A significant reductionin the risk of progression was associated with FOLFIRI (HR, 0.76; 95%CI, 0.62-0.95; P <0.01), a result partly dueto poor tolerance to the XELIRI regimens used.
Data from a randomised clinical study (Souglakos et al, 2012) comparing FOLFIRI + bevacizumab with XELIRI + bevacizumab showed no significant differences in PFS or OS between treatments.
Patients were randomised to receive either FOLFIRI plus bevacizumab (Arm-A, n=167) or XELIRI plus bevacizumab (Arm-B, n-166). For Arm B, the XELIRI regimen used capecitabine 1000 mg/m2 twice daily for 14 days + irinotecan 250 mg/m2 on day 1. Median progressionfree survival (PFS) was 10.0 and 8.9 months; p=0.64, overall survival 25.7 and 27.5 months; p=0.55 and response rates 45.5 and 39.8%; p=0.32 for FOLFIRI-Bev and XELIRI-Bev, respectively. Patients treated with XELIRI + bevacizumab reported a significantly higher incidence of diarrhoea, febrile neutropenia and hand-foot skin reactions than patients treated with FOLFIRI + bevacizumab with significantly increased treatment delays, dose reductions and treatment discontinuations.
Data from a multicentre, randomised, controlled phase II study (AIO KRK 0604) supports the use ofcapecitabine at a starting dose of 800 mg/m2 for 2 weeks every 3 weeks in combination with irinotecan andbevacizumab for the first-line treatment of patients with metastatic colorectal cancer. 120 Patients wererandomised to a modified XELIRI regimen with capecitabine 800 mg/m2 twice daily for two weeksfollowed by a 7-day rest period), irinotecan (200 mg/m2 as a 30 minute infusion on day 1 every 3 weeks), andbevacizumab (7.5 mg/kg as a 30 to 90 minute infusion on day 1 every 3 weeks ; 127 patients were randomised totreatment with capecitabine (1000 mg/m2 twice daily for two weeks followed by a 7-day rest period),oxaliplatin (130 mg/m2 as a 2 hour infusion on day 1 every 3 weeks), and bevacizumab (7.5 mg/kg as a 30 to 90 minute infusion on day 1 every 3 weeks). Following a mean duration of follow-up for the study population of26.2 months, treatment responses were as shown below:

Combination therapy in second-line treatment of metastatic colorectal cancer
Data from a multicentre, randomised, controlled phase III clinical study (NO16967) support the use of capecitabine in combination with oxaliplatin for the second-line treatment of metastastic colorectal cancer. In this trial, 627 patients with metastatic colorectal carcinoma who have received prior treatment with irinotecan in combination with a fluoropyrimidine regimen as first line therapy were randomised to treatment with XELOX or FOLFOX-4. For the dosing schedule of XELOX and FOLFOX-4 (without addition of placebo orbevacizumab), refer to table 6. XELOX was demonstrated to be non-inferior to FOLFOX-4 in terms of progression-free survival in the per-protocol population and intent-to-treat population (see table 9). The results indicate that XELOX is equivalent to FOLFOX-4 in terms of overall survival (see table 9). The median follow up at the time of the primary analyses in the intent- to-treat population was 2.1 years; data from analyses following an additional 6 months of follow up are also included in table 9.

Advanced gastric cancer:
Data from a multicentre, randomised, controlled phase III clinical trial in patients with advanced gastriccancer supports the use of capecitabine for the first-line treatment of advanced gastric cancer (ML17032). In thistrial, 160 patients were randomised to treatment with capecitabine (1000 mg/m2 twice daily for 2 weeksfollowed by a 7-day rest period) and cisplatin (80 mg/m2 as a 2-hour infusion every 3 weeks). A total of156 patients were randomised to treatment with 5-FU (800 mg/m2 per day, continuous infusion on days 1 to 5 every 3 weeks) and cisplatin (80 mg/m2 as a 2-hour infusion on day 1, every 3 weeks). Capecitabine incombination with cisplatin was non-inferior to 5-FU in combination with cisplatin in terms of progression-free survival in the per protocol analysis (hazard ratio 0.81; 95% CI 0.63 - 1.04). The median progression-free survival was 5.6 months (capecitabine + cisplatin) versus 5.0 months (5-FU + cisplatin). The hazard ratiofor duration of survival (overall survival) was similar to the hazard ratio for progression-free survival (hazard ratio 0.85; 95% CI 0.64 - 1.13). The median duration of survival was 10.5 months (capecitabine + cisplatin) versus 9.3 months (5-FU + cisplatin).
Data from a randomised multicentre, phase III study comparing capecitabine to 5-FU and oxaliplatin to cisplatinin patients with advanced gastric cancer supports the use of capecitabine for the first-line treatment of advanced gastric cancer (REAL-2). In this trial, 1002 patients were randomised in a 2x2 factorial design to one of the following 4 arms:
- ECF: epirubicin (50 mg/ m2 as a bolus on day 1 every 3 weeks), cisplatin (60 mg/m2 as a two hour infusionon day 1 every 3 weeks) and 5-FU (200 mg/m2 daily given by continuous infusion via a central line).
- ECX: epirubicin (50 mg/m2 as a bolus on day 1 every 3 weeks), cisplatin (60 mg/m2 as a two hour infusion on day 1 every 3 weeks), and capecitabine (625 mg/m2 twice daily continuously).
- EOF: epirubicin (50 mg/m2 as a bolus on day 1 every 3 weeks), oxaliplatin (130 mg/m2 given as a 2 hour infusion on day 1 every three weeks), and 5-FU (200 mg/m2 daily given by continuous infusion via a central line).
- EOX: epirubicin (50 mg/m2 as a bolus on day 1 every 3 weeks), oxaliplatin (130 mg/m2 given as a 2 hourinfusion on day 1 every three weeks), and capecitabine (625 mg/m2 twice daily continuously).
The primary efficacy analyses in the per protocol population demonstrated non-inferiority in overall survival for capecitabine- vs 5-FU-based regimens (hazard ratio 0.86; 95% CI 0.8 - 0.99) and for oxaliplatin- vs cisplatin-based regimens (hazard ratio 0.92; 95% CI 0.80 - 1.1). The median overall survival was 10.9 months incapecitabine-based regimens and 9.6 months in 5-FU based regimens. The median overall survival was 10.0 months in cisplatin-based regimens and 10.4 months in oxaliplatin-based regimens.
Capecitabine has also been used in combination with oxaliplatin for the treatment of advanced gastric cancer. Studies with capecitabine monotherapy indicate that capecitabine has activity in advanced gastric cancer.
Colon, colorectal and advanced gastric cancer: meta-analysis
A meta-analysis of six clinical trials (studies SO14695, SO14796, M66001, NO16966, NO16967, M17032) supports capecitabine replacing 5-FU in mono- and combination treatment in gastrointestinal cancer. The pooled analysis includes 3097 patients treated with capecitabine-containing regimens and 3074 patients treated with 5-FU-containing regimens. Median overall survival time was 703 days (95% CI: 671; 745) in patients treated with capecitabine-containing regimens and 683 days (95% CI: 646; 715) in patients treated with 5- FU-containing regimens. The hazard ratio for overall survival was 0.94 (95% CI: 0.89; 1.00, p=0.0489) indicating that capecitabine-containing regimens are non-inferior to 5-FU- containing regimens.
Breast cancer:
Combination therapy with capecitabine and docetaxel in locally advanced or metastatic breast cancer
Data from one multicentre, randomised, controlled phase III clinical trial support the use of capecitabine incombination with docetaxel for treatment of patients with locally advanced or metastatic breast cancer afterfailure of cytotoxic chemotherapy, including an anthracycline.
In this trial, 255 patients were ran domised to treatment with capecitabine (1250 mg/m2 twice daily for 2 weeks followed by 1-week rest period and docetaxel 75 mg/m2 as a 1 hour intravenous infusion every 3 weeks). 256patients were randomized to treatment with docetaxel alone (100 mg/m2 as a 1 hour intravenous infusion every 3 weeks).
Survival was superior in the capecitabine + docetaxel combination arm (p=0.0126).
Median survival was 442 days (capecitabine + docetaxel) vs. 352 days (docetaxel alone). The overall objective response rates in the all-randomised population (investigator assessment) were 41.6% (capecitabine + docetaxel) vs. 29.7% (docetaxel alone); p = 0.0058. Time to progressive disease was superior in the capecitabine +docetaxel combination arm (p<0.0001). The median time to progression was 186 days (capecitabine + docetaxel) vs. 128 days (docetaxel alone).
Monotherapy with capecitabine after failure of taxanes, anthracycline containing chemotherapy, and for whom anthracycline therapy is not indicated
Data from two multicentre phase II clinical trials support the use of capecitabine monotherapy for treatment ofpatients after failure of taxanes and an anthracycline-containing chemotherapy regimen or for whom further anthracycline therapy is not indicated. In these trials, a total of 236 patients were treated with capecitabine (1250mg/m2 twice daily for 2 weeks followed by 1-week rest period). The overall objective response rates (investigator assessment) were 20% (first trial) and 25% (second trial). The median time to progression was 93and 98 days. Median survival was 384 and 373 days.
All indications:
A meta-analysis of 14 clinical trials with data from over 4700 patients treated with capecitabine monotherapy orcapecitabine in combination with different chemotherapy regimens in multiple indications (colon, colorectal, gastric and breast cancer) showed that patients on capecitabine who developed hand-foot syndrome (HFS) had a longer overall survival compared to patients who did not develop HFS: median overall survival 1100 days (95%CI 1007;1200) vs 691 days (95% CI 638;754) with a hazard ratio of 0.61 (95% CI 0.56; 0.66).
The pharmacokinetics of capecitabine have been evaluated over a dose range of 502-3514 mg/m2/day. The parameters of capecitabine, 5'-deoxy-5-fluorocytidine (5'-DFCR) and 5'- deoxy-5-fluorouridine (5'-DFUR)measured on days 1 and 14 were similar. The AUC of 5-FU was 30%-35% higher on day 14. Capecitabine dose reduction decreases systemic exposure to 5-FU more than dose-proportionally, due to non-linear pharmacokinetics for the active metabolite.
Absorption
After oral administration, capecitabine is rapidly and extensively absorbed, followed by extensive conversion to the metabolites, 5'-DFCR and 5'-DFUR. Administration with food decreases the rate of capecitabine absorption, but only results in a minor effect on the AUC of 5'-DFUR, and on the AUC of the subsequent metabolite 5-FU. At the dose of 1250 mg/m2 on day 14 with administration after food intake, the peak plasma concentrations (Cmax in μg/ml) for capecitabine, 5'-DFCR, 5'-DFUR, 5-FU and FBAL were 4.67, 3.05, 12.1, 0.95 and 5.46 respectively. The time to peak plasma concentrations (Tmax in hours) were 1.50, 2.00, 2.00, 2.00 and 3.34. The AUC0-∞ values in μg•h/ml were 7.75, 7.24, 24.6, 2.03 and 36.3.
Distribution
In vitro human plasma studies have determined that capecitabine, 5'-DFCR, 5'-DFUR and 5- FU are 54%, 10%, 62% and 10% protein bound, mainly to albumin.
Biotransformation
Capecitabine is first metabolised by hepatic carboxylesterase to 5'-DFCR, which is then converted to 5'-DFUR by cytidine deaminase, principally located in the liver and tumour tissues. Further catalytic activation of 5'-DFUR then occurs by thymidine phosphorylase (ThyPase). The enzymes involved in the catalytic activation are found in tumour tissues but also in normal tissues, albeit usually at lower levels. The sequential enzymatic biotransformation of capecitabine to 5-FU leads to higher concentrations within tumour tissues. In the case ofcolorectal tumours, 5-FU generation appears to be in large part localised in tumour stromal cells. Following oral administration of capecitabine to patients with colorectal cancer, the ratio of 5-FU concentration in colorectaltumours to adjacent tissues was
3.2 (ranged from 0.9 to 8.0). The ratio of 5-FU concentration in tumour to plasma was 21.4 (ranged from 3.9 to 59.9, n=8) whereas the ratio in healthy tissues to plasma was 8.9 (ranged from 3.0 to 25.8, n=8). Thymidine phosphorylase activity was measured and found to be 4 times greater in primary colorectal tumour than inadjacent normal tissue. According to immunohistochemical studies, thymidine phosphorylase appears to be in large part localised in tumour stromal cells.
5-FU is further catabolised by the enzyme dihydropyrimidine dehydrogenase (DPD) to the much less toxic dihydro-5-fluorouracil (FUH2). Dihydropyrimidinase cleaves the pyrimidine ring to yield 5-fluoro-ureidopropionic acid (FUPA). Finally, β-ureido-propionase cleaves FUPA to α-fluoro-β-alanine (FBAL) which is cleared in the urine. Dihydropyrimidine dehydrogenase (DPD) activity is the rate limiting step. Deficiency of DPD may lead to increased toxicity of capecitabine (see section 4.3 and 4.4).
Elimination
The elimination half-life (t1/2 in hours) of capecitabine, 5'-DFCR, 5'-DFUR, 5-FU and FBAL were 0.85, 1.11, 0.66, 0.76 and 3.23 respectively. Capecitabine and its metabolites are predominantly excreted in urine; 95.5% of administered capecitabine dose is recovered in urine. Faecal excretion is minimal (2.6%). The major metabolite excreted in urine is FBAL, which represents 57% of the administered dose. About 3% of the administered dose isexcreted in urine unchanged.
Combination therapy
Phase I studies evaluating the effect of capecitabine on the pharmacokinetics of either docetaxel or paclitaxel and vice versa showed no effect by capecitabine on the pharmacokinetics of docetaxel or paclitaxel (Cmax and AUC) and no effect by docetaxel or paclitaxel on the pharmacokinetics of 5'-DFUR.
Pharmacokinetics in special populations
A population pharmacokinetic analysis was carried out after capecitabine treatment of 505 patients withcolorectal cancer dosed at 1250 mg/m2 twice daily. Gender, presence or absence of liver metastasis at baseline, Karnofsky Performance Status, total bilirubin, serum albumin, ASAT and ALAT had no statistically significant effect on the pharmacokinetics of 5'-DFUR, 5-FU and FBAL.
Patients with hepatic impairment due to liver metastases: According to a pharmacokinetic study in cancer patients with mild to moderate liver impairment due to liver metastases, the bioavailability of capecitabine and exposure to 5-FU may increase compared to patients with no liver impairment. There are no pharmacokinetic data on patients with severe hepatic impairment.
Patients with renal impairment: Based on a pharmacokinetic study in cancer patients with mild to severe renal impairment, there is no evidence for an effect of creatinine clearance on the pharmacokinetics of intact drug and 5-FU. Creatinine clearance was found to influence the systemic exposure to 5'-DFUR (35% increase in AUCwhen creatinine clearance decreases by 50%) and to FBAL (114% increase in AUC when creatinine clearance decreases by 50%). FBAL is a metabolite without antiproliferative activity.
Elderly: Based on the population pharmacokinetic analysis, which included patients with a wide range of ages(27 to 86 years) and included 234 (46%) patients greater or equal to 65, age has no influence on thepharmacokinetics of 5'-DFUR and 5-FU. The AUC of FBAL increased with age (20% increase in age results in a 15% increase in the AUC of FBAL).
This increase is likely due to a change in renal function.
Ethnic factors: Following oral administration of 825 mg/m2 capecitabine twice daily for 14 days, Japanese patients (n=18) had about 36% lower Cmax and 24% lower AUC for capecitabine than Caucasian patients(n=22). Japanese patients had also about 25% lower Cmax and 34% lower AUC for FBAL than Caucasian patients. The clinical relevance of these differences is unknown. No significant differences occurred in the exposure to other metabolites (5'-DFCR, 5'- DFUR, and 5-FU).
In repeat-dose toxicity studies, daily oral administration of capecitabine to cynomolgus monkeys and mice produced toxic effects on the gastrointestinal, lymphoid and haemopoietic systems, typical for fluoropyrimidines. These toxicities were reversible. Skin toxicity, characterised by degenerative/regressive changes, was observed with capecitabine.
Capecitabine was devoid of hepatic and CNS toxicities. Cardiovascular toxicity (e.g. PR- and QT-interval prolongation) was detectable in cynomolgus monkeys after intravenous administration (100 mg/kg) but not after repeated oral dosing (1379 mg/m2/day).
A two-year mouse carcinogenicity study produced no evidence of carcinogenicity by capecitabine.
During standard fertility studies, impairment of fertility was observed in female mice receiving capecitabine;however, this effect was reversible after a drug-free period. In addition, during a 13-week study, atrophic and degenerative changes occurred in reproductive organs of male mice; however these effects were reversible after a drug-free period (see section 4.6).
In embryotoxicity and teratogenicity studies in mice, dose-related increases in foetal resorption and teratogenicitywere observed. In monkeys, abortion and embryolethality were observed at high doses, but there was no evidence of teratogenicity.
Capecitabine was not mutagenic in vitro to bacteria (Ames test) or mammalian cells (Chinese hamsterV79/HPRT gene mutation assay). However, similar to other nucleoside analogues (ie, 5-FU), capecitabine was clastogenic in human lymphocytes (in vitro) and a positive trend occurred in mouse bone marrow micronucleus tests (in vivo).
