Zavedos contains an active ingredient called idarubicin hydrochloride, which belongs to a group of medicines called anthracyclines. Zavedos interferes with ways in which the cells of your body grow and increase in number and is used in the treatment of cancers (chemotherapy).
Zavedos is used in adults and children for the treatment of acute non lymphoblastic leukaemia (ANLL), also referred to as acute myeloid leukaemia (AML).
Zavedos is also used in adults and children as a second line treatment of relapsed acute lymphoblastic leukaemia (ALL).
Do not use Zavedos:
- If you have ever had an allergic (hypersensitivity) reaction to
- idarubicin or any of the other ingredients of this medicine (listed in section 6).
- other anthracyclines or anthracenediones.
- If your liver or kidneys are not working properly.
- If you have an infection which is not under control.
- If you have had a previous or current history of heart disease.
- If you have had a previous or current history of abnormal heart rhythms.
- If you have had previous or current history of bone marrow depression caused by previous therapy.
- If you have previously been treated with high doses of idarubicin hydrochloride and/ or other anthracyclines or anthracenediones.
- If you are breast-feeding.
Warnings and precautions
Talk to your doctor, pharmacist or nurse before you are given Zavedos if you:
- Suffer from bone marrow depression caused by previous therapy.
- Have suffered from heart trouble in the past or are presently receiving treatment for this.
- You have had a previous or current history of stomach problems (e.g. ulcer) or any problem with your bowels.
- Are taking or have recently taken trastuzumab (a medicine used in the treatment of certain cancers). Trastuzumab can take up to 7 months to be removed from the body. As trastuzumab may affect the heart, you should not use Zavedos for up to 7 months after you have stopped taking trastuzumab. If Zavedos is used before this time, then your heart function should be carefully monitored.
Zavedos may affect male fertility. Talk to your doctor about fertility preservation before starting treatment. Both men and women should use effective contraception (see “Pregnancy, breast-feeding and fertility” section).
If you desire to have children after Zavedos treatment, talk to you doctor about your options.
In these cases, Zavedos might not be a suitable treatment for you, or a reduced dose might have to be used.
Paediatric population
Babies and children are more at risk to heart problems that may be caused by taking Zavedos. Regular checks of the heart for a longer time will be needed.
Regular checks by your doctor during Zavedos treatment
Before starting and during treatment you will need regular checks including blood tests.
Your doctor will be making regular checks of:
- Your blood, to check for low blood cell counts that may need treatment.
- Your heart function, as Zavedos can have effects upon this.
- Your liver and kidneys – again using blood tests – to check that Zavedos is not affecting the way they function in a harmful way.
- Blood uric acid levels – Zavedos may increase uric acid levels in the blood, which might cause gout. Another medicine may be given if your uric acid levels are too high.
You will find more information on some of these effects in section 4.
Other medicines and Zavedos
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, in particular, if you:
- Are given medicines or were previously given medicines such as anthracyclines or anthracenediones that have a similar action to Zavedos. They can make the effects of Zavedos stronger.
- Are using Zavedos with medicines like calcium channel blockers or chemotherapies that have cardiac toxicity.
- Are receiving radiotherapy.
- Are taking oral drugs that prevent blood clots as it will require close monitoring.
- Are taking a medicine called Cyclosporin A.
You should not take live or live-attenuated vaccines (e.g. yellow fever) because of the risk of serious infection after treatment with chemotherapy.
Pregnancy, breast-feeding and fertility
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.
Pregnancy
Avoid becoming pregnant while you or your partner is being treated with Zavedos. Zavedos may harm an unborn baby, so it is important to tell your doctor if you think you are pregnant.
Contraception in women of childbearing potential
You should always use effective birth control (contraception) whilst receiving Zavedos and for at least 6.5 months after the last dose. Talk to your doctor about birth control methods that are right for you and your partner.
Contraception in men
Men should always use effective contraception whilst receiving Zavedos and for at least 3.5 months after the last dose.
Breast-feeding
Do not breast-feed whilst receiving Zavedos and for at least 14 days after the last dose, as some of the drug may get into your milk and possibly harm your child.
Fertility
Both men and women should seek advice on fertility preservation before treatment.
Driving and using machines
It is not known whether Zavedos has an effect on you being able to drive or use any tools or machines. However, special care should be taken if it is essential that you drive or operate machinery while undergoing treatment especially if you are lacking strength or are in a debilitated condition.
Zavedos will be given to you by injection into the veins. It should not be given by injection into your spine.
- Your doctor will prescribe the required amount (the dose). The dose is decided by taking into account your condition being treated, your height and weight.
- From your height and weight the doctor will work out your body surface area; this is necessary because the dose is usually calculated as "X milligrams per square metre" (mg/m2), given by injection, on 3 days running.
- However, your doctor may alter the dose and number of days of treatment depending on your condition and any other treatment you may receive.
If you receive more Zavedos than you should
High doses can worsen side effects like sores in the mouth or may decrease the number of white blood cells and platelets (these help the blood to clot) in the blood. Should this happen, you may need antibiotics or blood transfusions. Mouth ulcers can be treated to make them less uncomfortable as they heal.
Heart damage can occur when high doses of Zavedos are given. This may not be detected for several weeks, so regular tests may be required during this period.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Tell your doctor immediately if you experience any of the following symptoms after you have been given this medicine. Although they are very rare, the symptoms can be severe.

يحتوي زافيدوس على مكون فعال يسمى هيدروكلوريد إيداروبيسين ينتمي إلى مجموعة من الأدوية تسمى مركبات الأنثراسيكلين. يتداخل زافيدوس مع الطرق التي تنمو بها خلايا جسمك وتتكاثر، ويُستخدم في علاج السرطانات (العلاج الكيميائي).
يستخدم زافيدوس في البالغين والأطفال لعلاج سرطان الدم اللالمفاوي الحاد و سرطان الدم النخاعي الحاد.
يُستخدم زافيدوس أيضًا في البالغين والأطفال كخط علاج ثانٍ لابيضاض الدم الأرومي الليمفاوي الحاد (ALL) المنتكس.
موانع استعمال زافيدوس:
- إذا كنت قد أصبت من قبل بتفاعل حساسية (فرط حساسية) تجاه
- إيداروبيسين أو أي من المكونات الأخرى لهذا الدواء (المدرجة في القسم ٦).
- مركبات الأنثراسيكلين أو الأنثراسينيديون الأخرى.
- إذا كان كبدك أو كليتاك لا تعملان كما ينبغي.
- إذا كنت مصابًا بعدوى لم يتم التحكم بها بعد.
- إذا كان لديك تاريخ سابق أو حالٍ من الإصابة بأمراض القلب.
- إذا كان لديك تاريخ سابق أو حالٍ من الإصابة باضطراب ضربات القلب.
- إذا كان لديك تاريخ سابق أو حالٍ من الإصابة بكبت نخاع العظم تسبب فيه علاج سابق.
- إذا كان قد تم علاجك في السابق باستخدام جرعات عالية من هيدروكلوريد إيداروبيسين و/أو مركبات الأنثراسيكلين أو الأنثراسينيديون الأخرى.
- إذا كنتِ ترضعين رضاعة طبيعية.
الاحتياطات عند استعمال زافيدوس
تحدث مع طبيبك أو الصيدلي أو الممرضة قبل أن يتم إعطاؤك زافيدوس إذا:
- كنت تعاني من كبت نخاع العظم سببه علاج سابق.
- كنت قد عانيت في الماضي من مشكلة في القلب، أو كنت تتلقى حاليًا علاجًا لهذه المشكلة.
- كان لديك تاريخ سابق أو حالٍ من الإصابة بمشكلات المعدة (مثل القرحة) أو أي مشكلة في أمعائك.
- في هذه الحالات، قد لا يكون زافيدوس علاجًا ملائمًا لك، أو قد تكون هناك حاجة للجوء إلى جرعة مخفضة.
- كنت تتناول أو تناولت مؤخرًا تراستوزوماب (دواء يُستخدم في علاج بعض أنواع السرطانات). يمكن لتراستوزوماب أن يستغرق مدة تصل إلى ٧ أشهر حتى يتخلص منه الجسم. نظرًا لأن تراستوزوماب قد يؤثر على القلب، ينبغي ألا تستخدم زافيدوس لمدة تصل إلى ٧ أشهر بعد توقفك عن تناول تراستوزوماب. إذا استخدم زافيدوس قبل هذه المدة، ينبغي حينئذ أن تُراقب وظائف القلب لديك بدقة.
قد يؤثر زافيدوس على الخصوبة لدى الذكور. تحدث إلى طبيبك عن الحفاظ على الخصوبة قبل البدء في العلاج. ينبغي لكل من السيدات والرجال استخدام وسيلة فعالة لمنع الحمل (انظر قسم "الحمل والرضاعة والخصوبة").
إذا كنت ترغب في إنجاب الأطفال بعد العلاج بزافيدوس، فتحدث إلى طبيبك عن الخيارات المتاحة أمامك.
فئة الأطفال
يعتبر الرضع والأطفال أكثر عرضة لخطر الإصابة بمشكلات القلب التي قد يسببها تناول زافيدوس. لذا سيلزم إجراء فحوصات منتظمة للقلب لمدة أطول.
الفحوصات المنتظمة التي يجريها طبيبك أثناء العلاج باستخدام زافيدوس
ستحتاج قبل بدء العلاج وأثناء تلقيه إلى الخضوع لفحوصات منتظمة بما في ذلك فحوصات الدم.
سيجري طبيبك فحوصات منتظمة لـ:
- دمك، للتحقق من عدم انخفاض تعداد خلايا دمك، الأمر الذي قد يتطلب العلاج.
- وظائف قلبك، لأن زافيدوس قد يكون له آثار عليها.
- كبدك وكليتيك، أيضًا باستخدام فحوصات الدم، للتأكد من أن زافيدوس لا يؤثر بشكل مؤذٍ على الطريقة التي يعملان بها.
- مستويات حمض اليوريك في الدم، حيث يمكن أن يزيد زافيدوس من مستويات حمض اليوريك في الدم، مما قد يتسبب في الإصابة بالنقرس. قد يتم إعطاؤك دواءً آخر إذا كانت مستويات حمض اليوريك لديك مرتفعة للغاية.
ستجد المزيد من المعلومات حول بعض هذه الآثار في القسم ٤.
التداخلات الدوائية مع أخذ هذا المستحضر مع أي أدوية أخرى أو أعشاب أو مكملات غذائية
أخبر طبيبك أو الصيدلي إذا كنت تتناول أو قد تناولت مؤخرًا أو قد تتناول أي أدوية أخرى، وبصفة خاصة، إذا:
- كان يتم إعطاؤك أو تم إعطاؤك فيما سبق أدوية مثل مركبات الأنثراسيكلين أو الأنثراسينيديون التي لها تأثير مشابه لزافيدوس. لأنها يمكن أن تزيد من شدة آثار زافيدوس.
- كنت تستخدم زافيدوس بالتزامن مع أدوية مثل حاصرات قنوات الكالسيوم أو العلاجات الكيميائية التي تسبب السمية القلبية.
- كنت تتلقى العلاج الإشعاعي.
- كنت تتناول عقاقير عن طريق الفم تمنع تكوّن الجلطات الدموية لأن في هذه الحالة ستلزم مراقبة حالتك عن كثب.
- كنت تتناول دواءً يسمى سيكلوسبورين أ.
ينبغي ألا تتناول اللقاحات الحية أو اللقاحات الحية الموهنة (مثل لقاح الحمى الصفراء) بسبب وجود احتمال للإصابة بعدوى خطيرة بعد العلاج باستخدام العلاج الكيميائي.
الحمل والرضاعة والخصوبة
إذا كنتِ حاملًا أو ترضعين رضاعة طبيعية أو تعتقدين أنكِ ربما تكونين حاملًا أو تخططين للإنجاب، فاستشيري طبيبكِ أو الصيدلي قبل تناول هذا الدواء.
الحمل
تجنبي الحمل أثناء خضوعكِ أو خضوع زوجكِ للعلاج باستخدام زافيدوس. قد يلحق زافيدوس الأذى بالأجنة، لذا من المهم أن تخبري طبيبكِ إذا كنتِ تعتقدين أنكِ حامل.
وسائل منع الحمل في حالة السيدات في سن الإنجاب
ينبغي لكِ دائمًا استخدام وسيلة فعالة لتحديد النسل (وسائل منع الحمل) أثناء تلقي زافيدوس ولمدة ٦٬٥ أشهر على الأقل بعد تلقي آخر جرعة. تحدثي إلى طبيبكِ عن وسائل تحديد النسل المناسبة لكِ ولزوجكِ.
وسائل منع الحمل في حالة الرجال
ينبغي للرجال دائمًا استخدام وسيلة فعالة لمنع الحمل أثناء تلقي زافيدوس ولمدة ٣٬٥ أشهر على الأقل بعد تلقي آخر جرعة.
الرضاعة الطبيعية
لا تقومي بالرضاعة الطبيعية أثناء تلقيكِ زافيدوس ولمدة ١٤ يومًا على الأقل بعد تلقي آخر جرعة، حيث إن بعض العقار قد ينتقل إلى لبن الثدي الخاص بكِ ويحتمل أن يؤذي طفلكِ.
الخصوبة
ينبغي لكل من الرجال والسيدات طلب المشورة فيما يتعلق بالحفاظ على الخصوبة قبل العلاج.
تأثير زافيدوس على القيادة واستخدام الآلات
ليس معروفًا إذا ما كان لزافيدوس أثر على قدرتك على القيادة أو استخدام أي أدوات أو آلات أم لا. ومع ذلك، ينبغي توخي الحذر بشكل خاص إذا كان من الضروري أن تقوم بالقيادة أو تشغيل آلات أثناء الخضوع للعلاج خاصةً إذا كانت تنقصك القوة أو إذا كنت تشعر بحالة من الضعف.
سيُعطى زافيدوس إليك عن طريق الحقن في الوريد. ينبغي عدم إعطائه عن طريق الحقن في عمودك الفقري.
- سيصف لك طبيبك الكمية المطلوبة (الجرعة). تُحدد الجرعة بالأخذ في الاعتبار حالتك التي يتم علاجها وطولك ووزنك.
- سيحدد الطبيب مساحة سطح جسمك عن طريق وزنك وطولك؛ وهذا ضروري لأنه عادةً ما يتم حساب الجرعة بحيث تمثل "X مليجرامات لكل متر مربع". (ملجم/متر٢)، تُعطى عن طريق الحقن لثلاثة أيام متتالية.
- ومع ذلك، قد يقوم طبيبك بتغيير الجرعة وعدد أيام العلاج وفقًا لحالتك وأي علاج آخر قد تتلقاه.
الجرعة الزائدة من زافيدوس
يمكن أن تسبب الجرعات العالية تفاقم الآثار الجانبية مثل التقرحات في الفم أو قد تقلل من عدد خلايا الدم البيضاء والصفيحات الدموية (التي تساعد الدم على التخثر) في الدم. إذا حدث هذا، فقد تحتاج إلى تلقي مضادات حيوية أو عمليات نقل دم. يمكن علاج قرح الفم لجعلها أقل إزعاجًا أثناء التئامها.
يمكن أن يحدث تلف قلبي عند إعطاء جرعات عالية من زافيدوس. وقد لا يتم اكتشاف هذا لعدة أسابيع، لذا قد يلزم إجراء اختبارات بشكل منتظم أثناء هذه الفترة.
إذا كان لديك أي أسئلة أخرى حول استخدام هذا الدواء، فاسأل طبيبك أو الصيدلي أو الممرضة.
كما هو الحال مع جميع الأدوية، قد يسبب هذا الدواء آثارًا جانبية، إلا أنها لا تصيب الجميع.
أخبر طبيبك على الفور إذا أصبت بأي من الأعراض التالية بعد إعطائك هذا الدواء. على الرغم من أن هذه الأعراض نادرة جدًا، فإنها يمكن أن تكون شديدة.

For second line treatment of relapsed acute lymphoblastic leukaemia (ALL).
Zavedos may be used in combination chemotherapy regimens involving other cytotoxic agents (see section 4.2).
Posology
Dosage is calculated on the basis of body surface area.
Acute myeloid leukaemia (AML)
Adults
12 mg/m2/day i.v. daily for 3 days in combination with cytarabine.
or
8 mg/m2/day i.v. daily for 5 days with/without combination.
Paediatric population
10-12 mg/m2/day i.v. daily for 3 days in combination with cytarabine.
Acute lymphoblastic leukaemia (ALL)
Adults

Paediatric population
10 mg/m2/day i.v. daily for 3 days, as a single agent.
NOTE: These are general guidelines. Refer to individual protocols for exact dosage.
All of these dosage schedules should, however, take into account the haematological status of the patient and the dosages of other cytotoxic drugs when used in combination.
Administration of a second course should be delayed in patients who develop severe mucositis until recovery from this toxicity has occurred and a dose reduction of 25% is recommended.
Method of administration
For intravenous use only (See Section 6.6 Special precautions for disposal and handling).
Not for intrathecal use.
General
Idarubicin should be administered only under the supervision of physicians experienced in the use of cytotoxic chemotherapy.
This ensures that immediate and effective treatment of severe complications of the disease and/or its treatment (e.g. haemorrhage, overwhelming infections) may be carried out.
Patients should recover from acute toxicities of prior cytotoxic treatment (such as stomatitis, neutropenia, thrombocytopenia, and generalized infections) before beginning treatment with idarubicin hydrochloride.
Haematological toxicity
Idarubicin is a potent bone marrow suppressant. Severe myelosuppression will occur in all patients given a therapeutic dose of this agent.
Haematological profiles should be assessed before and during each cycle of therapy with idarubicin, including differential white blood cell (WBC) counts.
A dose-dependent, reversible leukopenia and/or granulocytopenia (neutropenia) is the predominant manifestation of idarubicin haematologic toxicity and is the most common acute dose limiting toxicity of the drug.
Leukopenia and neutropenia are usually severe, thrombocytopenia and anaemia may also occur. Neutrophil and platelet counts usually reach their nadir 10 to 14 days after drug administration; however, cell counts generally return to normal levels during the third week.
During the phase of severe myelosuppression, deaths due to infections and/or haemorrhages have been reported.
Clinical consequences of severe myelosuppression include fever, infections, sepsis/septicaemia, septic shock, haemorrhage, tissue hypoxia or death. If febrile neutropenia occurs, treatment with an i.v. antibiotic is recommended.
Secondary leukaemia
Secondary leukaemia, with or without a preleukaemic phase, has been reported in patients treated with anthracyclines, including idarubicin. Secondary leukaemia is more common when such drugs are given in combination with DNA-damaging antineoplastic agents, when patients have been heavily pre-treated with cytotoxic drugs, or when doses of the anthracyclines have been escalated. These leukaemias can have a 1 to 3 year latency period.
Cardiac function
Cardiotoxicity is a risk of anthracycline treatment that may be manifested by early (i.e. acute) or late (i.e. delayed) events.
Early (i.e. acute) events
Early cardiotoxicity of idarubicin consists mainly of sinus tachycardia and/or electrocardiogram (ECG) abnormalities, such as non-specific ST-T wave changes. Tachyarrhythmias, including premature ventricular contractions and ventricular tachycardia, bradycardia, as well as atrioventricular and bundle-branch block have also been reported. These effects do not usually predict subsequent development of delayed cardiotoxicity, are rarely of clinical importance, and are generally not a reason for the discontinuation of idarubicin treatment.
Late (i.e. delayed) events
Delayed cardiotoxicity usually develops late in the course of therapy or within 2 to 3 months after treatment termination, but later events, several months to years after completion of treatment have also been reported. Delayed cardiomyopathy is manifested by reduced left ventricular ejection fraction (LVEF) and/or signs and symptoms of congestive heart failure (CHF) such as dyspnoea, pulmonary oedema, dependent oedema, cardiomegaly, hepatomegaly, oliguria, ascites, pleural effusion, and gallop rhythm. Subacute effects such as pericarditis/myocarditis have also been reported. Life-threatening CHF is the most severe form of anthracycline-induced cardiomyopathy and represents the cumulative dose-limiting toxicity of the drug.
Cumulative dose limits for i.v. or oral idarubicin hydrochloride have not been defined. However, idarubicin-related cardiomyopathy was reported in 5% of patients who received cumulative i.v. doses of 150 to 290 mg/m2. Available data on patients treated with oral idarubicin hydrochloride total cumulative doses up to 400 mg/m2 suggest a low probability of cardiotoxicity.
Cardiac function should be assessed before patients undergo treatment with idarubicin and must be monitored throughout therapy to minimize the risk of incurring severe cardiac impairment. The risk may be decreased through regular monitoring of LVEF during the course of treatment with prompt discontinuation of idarubicin at the first sign of impaired function. The appropriate quantitative method for repeated assessment of cardiac function (evaluation of LVEF) includes Multiple Gated Acquisition (MUGA) scan or echocardiography (ECHO). A baseline cardiac evaluation with an ECG and either a MUGA scan or an ECHO is recommended, especially in patients with risk factors for increased cardiotoxicity. Repeated MUGA or ECHO determinations of LVEF should be performed, particularly with higher, cumulative anthracycline doses. The technique used for assessment should be consistent throughout follow-up.
Risk factors for cardiac toxicity include active or dormant cardiovascular disease, prior or concomitant radiotherapy to the mediastinal/pericardial area, previous therapy with other anthracyclines or anthracenediones, and concomitant use of drugs with the ability to suppress cardiac contractility or cardiotoxic drugs (e.g. trastuzumab). Anthracyclines including idarubicin should not be administered in combination with other cardiotoxic agents unless the patient’s cardiac function is closely monitored (see section 4.5). Patients receiving anthracyclines after stopping treatment with other cardiotoxic agents, especially those with long half-lives such as trastuzumab, may also be at an increased risk of developing cardiotoxicity. The reported half-life of trastuzumab is variable. The substance may persist in circulation for up to 7 months. Therefore, physicians should avoid anthracycline-based therapy for up to 7 months after stopping trastuzumab when possible. If this is not possible, the patient’s cardiac function should be monitored carefully.
Cardiac function monitoring must be particularly strict in patients receiving high cumulative doses and in those with risk factors. However, cardiotoxicity with idarubicin may occur at lower cumulative doses whether or not cardiac risk factors are present.
In infants and children there appears to be a greater susceptibility to anthracycline induced cardiac toxicity, and a long-term periodic evaluation of cardiac function has to be performed.
It is probable that the toxicity of idarubicin and other anthracyclines or anthracenediones is additive.
Hepatic and renal function
Since hepatic and/or renal function impairment can affect the disposition of idarubicin, liver and kidney function should be evaluated with conventional clinical laboratory tests (using serum bilirubin and serum creatinine as indicators) prior to, and during, treatment. In a number of Phase III clinical trials, treatment was contraindicated if bilirubin and/or creatinine serum levels exceeded 2.0 mg %. With other anthracyclines a 50% dose reduction is generally used if bilirubin levels are in the range 1.2-2.0 mg %.
Gastrointestinal
Idarubicin is emetogenic. Mucositis (mainly stomatitis, less often oesophagitis) generally appears early after drug administration and, if severe, may progress over a few days to mucosal ulcerations. Most patients recover from this adverse event by the third week of therapy.
Occasionally, episodes of serious gastrointestinal events (such as perforation or bleeding) have been observed in patients receiving oral idarubicin who had acute leukaemia or a history of other pathologies or had received medications known to lead to gastrointestinal complications. In patients with active gastrointestinal disease with increased risk of bleeding and/or perforation, the physician must balance the benefit of oral idarubicin therapy against the risk.
Effects at site of injection
Phlebosclerosis may result from an injection into a small vessel or from previous injections into the same vein. Following the recommended administration procedures may minimise the risk of phlebitis/thrombophlebitis at the injection site (See Section 6.6 Special precautions for disposal and handling).
Extravasation
Extravasation of idarubicin during intravenous injection may cause local pain, severe tissue lesions (vesication, severe cellulitis), and necrosis. Should signs or symptoms of extravasation occur during intravenous administration of idarubicin, the drug infusion should be immediately stopped (See Section 6.6 Special precautions for disposal and other handling).
In cases of extravasation dexrazoxane can be used to prevent or reduce tissue injury.
Tumour lysis syndrome
Idarubicin may induce hyperuricaemia as a consequence of the extensive purine catabolism that accompanies rapid drug-induced lysis of neoplastic cells (‘tumour lysis syndrome’). Blood uric acid levels, potassium, calcium phosphate, and creatinine should be evaluated after initial treatment. Hydration, urine alkalinisation, and prophylaxis with allopurinol to prevent hyperuricaemia may minimize potential complications of tumour lysis syndrome.
Immunosuppressant effects/increased susceptibility to infections
Administration of live or live-attenuated vaccines (like yellow fever) in patients immunocompromised by chemotherapeutic agents including idarubicin, may result in serious or fatal infections. Vaccination with a live vaccine should be avoided in patients receiving idarubicin. Killed or inactivated vaccines may be administered; however, the response to such vaccines may be diminished.
Reproductive system
Idarubicin can cause genotoxicity. Male and female patients treated with idarubicin hydrochloride are advised to adopt effective contraceptive measures during therapy and for a period after treatment.
Men treated with idarubicin hydrochloride are advised, if appropriate and available, to seek advice on sperm preservation due to the possibility of irreversible infertility caused by the therapy (see section 4.6). Patients desiring to have children after completion of therapy should be advised to discuss with an appropriate specialist first.
Other
As with other cytotoxic agents, thrombophlebitis and thromboembolic phenomena, including pulmonary embolism have been coincidentally reported with the use of idarubicin.
The product may cause a red colouration of the urine for 1-2 days after administration and patients should be advised of this fact.
Idarubicin is a potent myelosuppressant and combination chemotherapy regimens including other agents with similar action may be expected to induce additive myelosuppressive effects (see section 4.4).
Changes in hepatic or renal function induced by concomitant therapies may affect idarubicin metabolism, pharmacokinetics and therapeutic efficacy and/ or toxicity (see section 4.4).
The use of idarubicin in combination chemotherapy with other potentially cardiotoxic drugs, as well as the concomitant use of other cardioactive compounds (e.g. calcium channel blockers), requires monitoring of cardiac function throughout treatment. An additive myelosuppressant effect may occur when radiotherapy is given concomitantly or within 2-3 weeks prior to treatment with idarubicin.
Concomitant use of live attenuated vaccines (e.g. yellow fever) is not recommended, due to a risk of possibly fatal systemic disease. The risk is increased in subjects who are already immunosuppressed by their underlying disease. An inactivated vaccine should be used if available.
At combination of oral anticoagulants and anticancer chemotherapy, increased frequency of the INR (International Normalised Ratio) monitoring is recommended, since the risk for an interaction cannot be excluded.
Cyclosporin A: The co-administration of cyclosporin A as a single chemosensitizer significantly increased idarubicin AUC (1.78-fold) and idarubicinol AUC (2.46-fold) in patients with acute leukaemia. The clinical significance of this interaction is unknown. A dosage adjustment may be necessary in some patients.
Pregnancy
There are limited amount of data from the use of idarubicin in pregnant women. Studies in animals have shown reproductive toxicity (see section 5.3). Idarubicin should not be used during pregnancy unless the potential benefit justifies the potential risk to the foetus. The patient should be informed of the potential hazard to the foetus.
Women of childbearing potential / Contraception in males and females
Women of childbearing potential should be advised not to become pregnant and to use effective contraception during treatment with idarubicin and for at least 6.5 months after the last dose. Men with female partners of childbearing potential should be advised to use effective contraception during treatment with idarubicin and for at least 3.5 months after the last dose (see section 4.4).
Breast-feeding
It is not known whether idarubicin or its metabolites are excreted in human milk. As other anthracyclines are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from idarubicin, women should be advised not to breastfeed during treatment with idarubicin and for at least 14 days after the last dose.
Fertility
Idarubicin can induce chromosomal damage in human spermatozoa. Both men and women should seek advice on fertility preservation before treatment.
The effect of idarubicin on the ability to drive or use machinery has not been systematically evaluated.

Description of selected adverse reactions
Haematopoietic system
Pronounced myelosuppression is the most severe adverse effect of idarubicin treatment. However, this is necessary for the eradication of leukaemic cells (see section 4.4).
Cardiotoxicity
Life-threatening CHF is the most severe form of anthracycline-induced cardiomyopathy and represents the cumulative dose-limiting toxicity of the drug (see section 4.4).
Gastrointestinal
Stomatitis and in severe cases ulceration of mucosa, dehydration caused by severe vomiting and diarrhoea; risk of perforation of colon etc.
Administration site
Phlebitis/thrombophlebitis and prevention measures discussed in section 4.2; unintended paravenous infiltrates may cause pain, severe cellulites and tissue necrosis.
Other adverse reactions: hyperuricaemia
Prevention of symptoms by hydration, urine alkalinisation, and prophylaxis with allopurinol may minimise potential complications of tumour lysis syndrome.
Paediatric population
Undesirable effects are similar in adults and children except a greater susceptibility to anthracycline-induced cardiac toxicity of children (see section 4.4).

Very high doses of idarubicin may be expected to cause acute myocardial toxicity within 24 hours and severe myelosuppression within one to two weeks. Delayed cardiac failure has been seen with the anthracyclines up to several months after the overdose. Patients treated with oral idarubicin should be observed for possible gastrointestinal haemorrhage and severe mucosal damage.
Pharmacotherapeutic group: Anthracyclines and related substances
ATC Code: L01DB06
Idarubicin is a DNA intercalating anthracycline which interacts with the enzyme topoisomerase II and has an inhibitory effect on nucleic acid synthesis.
The modification of position 4 of the anthracycline structure gives the compound a high lipophilicity which results in an increased rate of cellular uptake compared with doxorubicin and daunorubicin.
Idarubicin has been shown to have a higher potency with respect to daunorubicin and to be an effective agent against murine leukaemia and lymphomas both by i.v. and oral routes. Studies in-vitro on human and murine anthracycline-resistant cells have shown a lower degree of cross-resistance for idarubicin compared with doxorubicin and daunorubicin. Cardiotoxicity studies in animals have indicated that idarubicin has a better therapeutic index than daunorubicin and doxorubicin. The main metabolite, idarubicinol, has shown, in-vitro and in-vivo, antitumoural activity in experimental models. In the rat, idarubicinol administered at the same doses as the parent drug, is clearly less cardiotoxic than idarubicin.
In vitro studies have shown plasma protein binding of at least 95% for this product. This fact should be borne in mind when considering its use in combination with other drugs.
In adults, following oral administration of 10 to 60 mg/m2 idarubicin, idarubicin was rapidly absorbed with the maximum plasma concentrations of 4-12.65 ng/mL achieved in 1 to 4 hours after dosing. The terminal half-life was 12.7±6.0 hrs (mean±SD). Following intravenous administration of idarubicin in adults, the terminal half-life was 13.9±5.9 hrs, similar to that observed after the oral administration.
After i.v. administration, idarubicin is extensively metabolised to an active metabolite, idarubicinol, which is slowly eliminated with a plasma T½ ranging between 41-69 hours). The drug is eliminated by biliary and renal excretion, mostly in the form or idarubicinol.
Studies of cellular (nucleated blood and bone marrow cells) in leukaemic patients have shown that peak cellular idarubicin concentrations are reached a few minutes after injection.
Idarubicin and idarubicinol concentrations in nucleated blood and bone marrow cells are more than a hundred times the plasma concentrations. Idarubicin disappearance rates in plasma and cells were comparable, with a terminal half-life of about 15 hours. The terminal half-life of idarubicinol in cells was about 72 hours.
Paediatric population
Pharmacokinetic measurements in 7 paediatric patients receiving intravenous idarubicin hydrochloride in doses ranging from 15 to 40 mg/m2 over the 3 days of treatment, showed a median idarubicin half-life of 8.5 hrs (range: 3.6-26.4 hrs). The active metabolite, idarubicinol, accumulated during the 3 days of treatment, exhibiting a median half-life of 43.7 hrs (range: 27.8-131 hrs). In a separate study, pharmacokinetic measurements in 15 paediatric patients receiving oral idarubicin hydrochloride in doses ranging from 30 to 50 mg/m2 during the 3 days of treatment, the maximum plasma concentration of idarubicin was 10.6 ng/mL (range 2.7-16.7 ng/mL at the 40 mg/m2 dose). The median terminal half-life of idarubicin of was 9.2 hrs (range: 6.4-25.5 hrs). Significant accumulation of idarubicinol was seen over the 3 day treatment period. The observed terminal half-life value of idarubicin after i.v. was comparable to that following oral administration in paediatric patients.
Since Cmax of idarubicin is similar in children and adults following oral administrations, absorption kinetics seem not to differ between adults and children.
Following both oral and i.v. administrations, the elimination half-life values of idarubicin in children and adults differ.
Total body clearance values of 30-107.9 L/h/m2 for idarubicin reported for adults are higher than the values of 18-33 L/h/m2 reported for paediatric populations. Although idarubicin has a very large volume of distribution in both adults and children, suggesting that much of the drug is bound to tissues, the shorter elimination half-life and lower total body clearance are not entirely explained by a smaller apparent volume of distribution in children compared to adults.
Idarubicin has mutagenic properties and it is carcinogenic in rats.
Reproduction studies in animals have shown that idarubicin is embryotoxic and teratogenic in rats but not rabbits.

Unopened vial: Store and transport refrigerated (2°C - 8°C), Do not freeze, and protect from light.
Opened vial: From a microbiological point of view, unless the method of opening/dilution precludes the risk of microbial contamination, this medicinal product should be used immediately. If not used immediately, in-use storage times and conditions are the responsibility of the user.
Keep the vial in the outer carton in order to protect from light.
Polypropylene vials which are closed with a siliconised, halobutyl rubber stopper and sealed with an aluminium cap with a plastic flip off top.
Zavedos is available in 5 mL, and 10 mL vials packed singly in cartons.
Preparation and precautions:
The following protective recommendations are given due to the toxic nature of this substance:
· This product should be handled only by personnel who have been trained in the safe handling of such preparations.
· Pregnant staff should be excluded from working with this drug.
· Personnel handling Zavedos should wear protective clothing: goggles, gowns and disposable gloves and masks.
· Any work surfaces used should be protected by disposable, plastic-backed, absorbent paper.
· The solution should not be allowed to contact mucous membranes, eyes or skin. Accidental contact with the skin and eyes should be treated immediately by copious lavage with water, or sodium bicarbonate solution, medical attention should be sought.
· Spillage or leakage should be treated with dilute sodium hypochlorite (1% available chlorine) solution, preferably by soaking, and then with water.
Intravenous administration:
Administration ZAVEDOS for injection contains no antimicrobial preservative. Use in one patient on one occasion only. Discard any residue.
ZAVEDOS for injection must be administrated only by the intravenous route and the reconstituted solution should be given via tubing of a freely running intravenous infusion of 0.9% Sodium Chloride Injection, taking 10-15 minutes over the injection.
The tubing should be attached to a butterfly needle or other suitable device and inserted preferably into a large vein. This technique minimises the risk of thrombosis or perivenous extravasation, which can lead to severe cellulitis and necrosis. Venous sclerosis may result from injection into small veins or repeated injections in the same vein.
Care in the administration of ZAVEDOS will reduce the chance of perivenous infiltration. It may also decrease the chance of local reactions such as urticaria and erythematous streaking.
During intravenous administration of ZAVEDOS, extravasation may occur with or without an accompanying stinging or burning sensation, even if blood returns well on aspiration of the infusion needle. If any signs or symptoms of extravasation have occurred, the injection or infusion should be immediately terminated and restarted in another vein. If it is known or suspected that subcutaneous extravasation has occurred, it is recommended that intermittent ice packs (½ hour immediately, then ½ hour 4 times per day for 3 days) be placed on the area of extravasation and that the affected extremity be elevated.
In cases of extravasation dexrazoxane can be used to prevent or reduce tissue injury. If used, dexrazoxane should be administered in a large vein in an area away from the extravasation (i.e the opposite arm).
Because of the progressive nature of extravasation reactions, the area of injection should be frequently examined and plastic surgery consultations obtained early if there is any sign of local reaction such as pain, erythema, oedema or vesication. If ulceration begins or there is persistent pain at the site of extravasation, early wide excision of the involved area should be considered.”
Disposal:
All items used for administration or cleaning, including gloves, should be placed in high risk, waste disposal bags for high temperature incineration.
For single use only. Any unused solution should be discarded.
