Braftovi is an anti-cancer medicine that contains the active substance encorafenib. Changes (mutations) in the BRAF gene can produce proteins that cause the cancer to grow. Braftovi targets proteins made from this changed BRAF gene.

 

It is used in combination with another medicine containing binimetinib to treat

·         patients with a type of skin cancer called melanoma when it has

-                 a particular change (mutation) in a gene responsible for producing a protein called BRAF, and

-                 spread to other parts of the body, or cannot be removed by surgery

·         adults with a type of lung cancer called non-small cell lung cancer (NSCLC):

-                 that has spread to other parts of the body, and

-                 that has a certain type of abnormal “BRAF” gene

When Braftovi is used in combination with binimetinib, which targets another protein that stimulates cancer cell growth, the combination slows down or stops the growth of your cancer.

 

Braftovi is also used in combination with another medicine cetuximab, to treat adult patients with colorectal cancer (cancer of colon or rectum) when it has

-                 a particular change (mutation) in a gene responsible for producing a protein called BRAF, and

-                 spread to other parts of the body of patients, and

-                 been previously treated with other anticancer medicines

When Braftovi is used in combination with cetuximab (which binds to the epidermal growth factor receptor (EGFR)), a protein on the surface of certain cancer cells), the combination slows down or stops the growth of your cancer.

 

BRAFTOVI should not be used to treat people with wild-type BRAF melanoma, wild-type BRAF colorectal cancer, or wild-type BRAF NSCLC. Your healthcare provider will perform a test to make sure that BRAFTOVI is right for you.


Before starting treatment your doctor will check for the BRAF mutation.

 

As Braftovi is to be used in combination with binimetinib to treat melanoma, read the binimetinib leaflet carefully as well as this leaflet. 

 

As Braftovi is to be used in combination with cetuximab to treat colorectal cancer, read the cetuximab leaflet carefully as well as this leaflet. 

 

Do not take Braftovi

-                 if you are allergic to encorafenib or any of the other ingredients of this medicine (listed in section 6).

 

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Braftovi, about all of your medical conditions, particularly if you have any of the following:

-                 heart problems including alteration of the electrical activity of your heart (QT interval prolongation)

-                 bleeding problems or if you are taking medicines that may cause bleeding

-                 eye problems

-                 low blood levels of potassium, calcium, or magnesium

-                 liver or kidney problems

 

Tell your doctor if you have had a different type of cancer than melanoma or colorectal cancer, as Braftovi may worsen certain other types of cancers.

 

Tell your doctor, pharmacist or nurse immediately if you get the following while you are taking this medicine:

-                 Heart problems: Braftovi when taken with binimetinib can cause heart problem. Your doctor will check that your heart is working properly before and during your treatment with these medicines. Talk to your doctor immediately if you have any symptoms of heart problems such as feeling dizzy, tired, lightheaded, if you have shortness of breath, if you feel like your heart is pounding, racing, or if you have swelling in the hands, ankles legs or feet.

 

-                 Changes in the electrical activity of your heart called QT prolongation: QT prolongation can cause irregular heartbeats that can be life threatening. Your doctor provider should do tests before you start taking BRAFTOVI with binimetinib or cetuximab and during your treatment to check your body salts (electrolytes). Tell your doctor right away if you feel faint, lightheaded, dizzy or if you feel your heart beating irregularly or fast during treatment with BRAFTOVI and binimetinib or cetuximab. These symptoms may be related to QT prolongation.

 

-                 Bleeding problems: Braftovi may cause serious bleeding problems including in stomach or brain that can lead to death. Talk to your doctor immediately if you have any symptoms of bleeding problems such as coughing up of blood, blood clots, vomit containing blood or that looks like “coffee grounds”, red or black stools that look like tar, passing blood in the urine, stomach (abdominal) pain, unusual vaginal bleeding. Also tell your doctor if you have headache, dizziness or weakness.

 

-                 Eye problems: Braftovi, when taken with binimetinib, can cause serious eye problems. Talk to your doctor immediately if you get blurred vision, loss of vision, or other vision changes (e.g. coloured dots in your vision), halo (seeing blurred outline around objects). Your doctor will examine your eyes for any problems with your sight while you are taking Braftovi.

 

-                 Skin changes: Braftovi may cause other types of skin cancer such as cutaneous squamous cell carcinoma or basal cell carcinoma. New melanomas may also occur while taking Braftovi. Your doctor will check your skin for any new skin cancers before treatment, every 2 months during treatment, and for up to 6 months after you stop taking Braftovi. Tell your doctor immediately if you detect skin changes during and after treatment including: new wart, skin sore or reddish bump that bleeds or does not heal, or a change in size or colour of a mole. Additionally, your doctor needs to check for squamous cell carcinoma on your head, neck, mouth and lymph glands, and you will have CT scans regularly. This is a precaution in case a squamous cell carcinoma develops inside your body.

 

-                 Liver problems: Braftovi can cause abnormal blood tests related to how your liver works (raised levels of liver enzymes). Your doctor will run blood tests to check your liver before and during treatment.

 

-                 Kidney problems: Braftovi can alter your kidney activity (often abnormal blood tests, more rarely dehydration and vomiting). Your doctor will run blood tests to monitor your kidneys before and during treatment. Drink plenty of fluids during treatment. Tell your doctor immediately if you vomit and become dehydrated.

برافتوفي هو دواء مضاد للسرطان يحتوي على المادة الفعالة إنكورافينيب. يمكن أن تؤدي التغيرات (الطفرات) في جين BRAF إلى إنتاج بروتينات تتسبب في نمو السرطان. ويستهدف برافتوفي البروتينات الناتجة عن جين BRAF المتغير هذا.

 

يتم استخدام برافتوفي مع دواء آخر يحتوي على بينيميتينيب لعلاج

·            المرضى المصابين بنوع من سرطان الجلد يسمى الورم الميلانيني عند

-                 وجود تغير (طفرة) معين في الجين المسؤول عن إنتاج بروتين يسمى BRAF،

-                 وانتشار الورم إلى أجزاء أخرى من الجسم، أو في حالة عدم القدرة على إزالته جراحيًا

·            لعلاج المرضى البالغين المصابين بنوع من سرطان الرئة يسمى سرطان الرئة ذا الخلايا غير الصغيرة (NSCLC):

-                 الذي ينتشر إلى أجزاء أخرى من الجسم،

-                 و لديه نوع معين غير طبيعي من الجين المسؤول عن إنتاج بروتين "BRAF"

عند استخدام برافتوفي مع بينيميتينيب، الذي يستهدف بروتينًا آخر يحفز نمو الخلايا السرطانية، يؤدي الجمع بينهما إلى إبطاء نمو السرطان الذي تعاني منه أو إيقافه.

 

يستخدم برافتوفي أيضًا مع دواء آخر يسمى سيتوكسيماب لعلاج المرضى البالغين المصابين بسرطان القولون والمستقيم (سرطان القولون أو المستقيم) عند

-                 وجود تغير (طفرة) معين في الجين المسؤول عن إنتاج بروتين يسمى BRAF،

-                 وانتشار السرطان إلى أجزاء أخرى من جسم المرضى،

-                 والذين سبق علاجهم باستخدام أدوية أخرى مضادة للسرطان

عند استخدام برافتوفي مع سيتوكسيماب (الذي يرتبط بمستقبل عامل نمو البشرة (EGFR)، وهو بروتين موجود على سطح بعض الخلايا السرطانية)، يؤدي الجمع بينهما إلى إبطاء نمو السرطان الذي تعاني منه أو إيقافه.

 

لا ينبغي استخدام برافتوفي لعلاج الأشخاص المصابين بالورم الميلانيني الذي تسببه الطفرة الطبيعية لجين BRAF، أو سرطان القولون والمستقيم الذي تسببه الطفرة الطبيعية لجين BRAF، أو سرطان الرئة ذو الخلايا غير الصغيرة الذي تسببه الطفرة الطبيعية لجين BRAF. سيقوم مقدم الرعاية الصحية الخاص بك بإجراء اختبار للتأكد من أن برافتوفي مناسب لك.

 

قبل بدء العلاج، سيفحصك طبيبك للتحقق من وجود طفرة BRAF.

 

نظرًا لاستخدام برافتوفي مع بينيميتينيب لعلاج الورم الميلانيني، اقرأ نشرة بينيميتينيب بعناية وكذلك هذه النشرة. 

 

نظرًا لاستخدام برافتوفي مع سيتوكسيماب لعلاج سرطان القولون والمستقيم، اقرأ نشرة سيتوكسيماب بعناية وكذلك هذه النشرة. 

 

موانع استعمال برافتوفي

-                 مشكلات في العين

-                 مستويات منخفضة من البوتاسيوم أو الكالسيوم أو المغنسيوم في الدم

-                 مشكلات في الكبد أو الكلى

 

أخبر طبيبك إذا كنت مصابًا بنوع مختلف من السرطان بخلاف الورم الميلانيني أو سرطان القولون والمستقيم، نظرًا لأن برافتوفي قد يؤدي إلى تفاقم حالة بعض آخر من أنواع السرطانات.

 

أخبر طبيبك أو الصيدلي أو الممرضة فورًا إذا أصبت بما يلي خلال فترة تناول هذا الدواء:

-                 مشكلات في القلب: عند تناول برافتوفي مع بينيميتينيب، يمكن أن يتسبب ذلك في حدوث مشكلة في القلب. سيتحقق طبيبك من أن قلبك يعمل بشكل سليم قبل وأثناء علاجك بهذين الدواءين. تحدث إلى طبيبك على الفور إذا كان لديك أي أعراض للإصابة بمشكلات في القلب مثل الشعور بالدوار، أو التعب، أو الدوخة، أو إذا كنت تعاني من ضيق التنفس، أو إذا شعرت بأن قلبك يخفق بشدة أو ضرباته متسارعة، أو إذا كنت تعاني من تورم في اليدين، أو الكاحلين، أو الساقين، أو القدمين.

 

-                  تغيرات في النشاط الكهربائي للقلب تسمى إطالة فترة QT: يمكن أن تسبب إطالة فترة QT ضربات قلب غير منتظمة يمكن أن تكون مهددة للحياة. يجب على طبيبك إجراء اختبارات قبل أن تبدأ في تناول برافتوفي مع بينيميتينيب أو سيتوكسيماب وأثناء العلاج للتحقق من أملاح الجسم (الإلكتروليتات). أخبر طبيبك على الفور إذا شعرت بالإغماء أو الدوار أو الدوخة أو إذا شعرت أن ضربات قلبك غير منتظمة أو سريعة أثناء العلاج ببرافتوفي مع بينيميتينيب أو سيتوكسيماب. قد تكون هذه الأعراض مرتبطة بإطالة فترة QT.

 

-                 مشكلات نزيف: قد يسبب برافتوفي مشكلات نزيف خطيرة، بما في ذلك في المعدة أو المخ، يمكن أن تؤدي إلى الوفاة. تحدث إلى طبيبك على الفور إذا كان لديك أي أعراض لمشكلات نزيف مثل السعال المصحوب بخروج الدم، جلطات الدم، القيء الذي يحتوي على دم أو الذي يشبه "ثفل القهوة"، البراز الأحمر أو الأسود الذي يشبه القطران، خروج دم في البول، آلام المعدة (البطن)، النزيف المهبلي غير المعتاد. أخبر طبيبك أيضًا إذا كنت تعاني من الصداع، أو الدوار، أو الضعف.

 

-                 مشكلات في العين: يمكن أن يسبب برافتوفي، عند تناوله مع بينيميتينيب، مشكلات خطيرة في العين. تحدث إلى طبيبك على الفور إذا كنت تعاني من تغيم الرؤية، أو فقدان الرؤية، أو تغيرات أخرى في الرؤية (مثل وجود نقاط ملونة في مجال رؤيتك)، أو رؤية هالات (رؤية إطار ضبابي حول الأشياء). سيقوم طبيبك بفحص عينيك بحثًا عن أي مشكلات في رؤيتك أثناء تناولك برافتوفي.

 

-                 تغيرات جلدية: قد يؤدي برافتوفي إلى الإصابة بنوع آخر من أنواع سرطان الجلد، مثل سرطانة الخلايا الحرشفية الجلدية أو سرطانة الخلايا القاعدية. قد تحدث أيضًا إصابة بأورام ميلانينية جديدة أثناء تناول برافتوفي. سيقوم طبيبك بفحص جلدك بحثًا عن أي سرطانات جلدية جديدة قبل العلاج، وكل شهرين أثناء العلاج، ولمدة تصل إلى ٦ أشهر بعد توقفك عن تناول برافتوفي. أخبر طبيبك على الفور إذا اكتشفت تغيرات جلدية أثناء وبعد العلاج بما في ذلك: الثآليل حديثة الظهور، أو القرح الجلدية، أو النتوءات المائلة للون الأحمر التي تنزف أو لا تُشفى، أو تغير في حجم أو لون شامة. بالإضافة إلى ذلك، يحتاج طبيبك إلى التحقق من إصابتك بسرطانة الخلايا الحرشفية في رأسك، وعنقك، وفمك، وغددك الليمفاوية، وستخضع لفحوصات بالتصوير المقطعي المحوسب (CT) بانتظام. وهذا إجراء احتياطي تحسبًا لظهور سرطانة الخلايا الحرشفية داخل جسمك.

 

-                 مشكلات في الكبد: يمكن أن يتسبب برافتوفي في نتائج غير طبيعية لفحوصات الدم المتعلقة بكيفية عمل كبدك (ارتفاع مستويات إنزيمات الكبد). سيقوم طبيبك بإجراء فحوصات دم لفحص كبدك قبل وأثناء العلاج.

 

-                 مشكلات في الكلى: يمكن أن يغير برافتوفي نشاط كليتيك (نتائج غير طبيعية لفحوصات الدم بشكل شائع، الإصابة بالجفاف والقيء في حالات أكثر ندرة). سيقوم طبيبك بإجراء فحوصات دم لمراقبة كليتيك قبل وأثناء العلاج. اشرب الكثير من السوائل أثناء العلاج. أخبر طبيبك على الفور إذا كنت تتقيأ وأُصبت بالجفاف.

إذا كنت مصابًا بمشكلات في الكبد أو الكلى، فقد يصف لك طبيبك جرعة أقل في البداية.

 إذا أصبت بأعراض جانبية خطيرة (مثل مشكلات القلب، أو العين، أو النزيف)، فقد يقلل طبيبك الجرعة أو يوقف العلاج مؤقتًا أو نهائيًا.

 

 طريقة استخدام برافتوفي

تعليمات فتح شريط البليستر:

-        لا تدفع الكبسولة لإخراجها من شريط البليستر.

-        افصل وحدة كبسولة من شريط البليستر عن طريق ثنيها وخلعها برفق بطول الخطوط المنثقبة.

-        قشر رقاقة شريط البليستر المعدنية بحرص بدءًا من الركن المعلم بسهم.

-        أخرج الكبسولة برفق.

 

يمكن تناول برافتوفي مع الطعام أو بين الوجبات.

 

إذا أصبت بالقيء

إذا تقيأت في أي وقت بعد تناول برافتوفي، فلا تتناول جرعة إضافية. تناول الجرعة التالية حسب ما هو مقرر.

 

الجرعة الزائدة من برافتوفي

إذا تناولت عددًا من الكبسولات أكثر مما ينبغي، فتواصل مع طبيبك أو الصيدلي أو الممرضة فورًا. أرِهم هذه النشرة وعبوة الدواء إن أمكن.

 

نسيان تناول جرعة برافتوفي

إذا فاتتك إحدى جرعات برافتوفي، فتناولها بمجرد تذكرها. ولكن إذا مر أكثر من ١٢ ساعة على موعد الجرعة الفائتة، فتخط تلك الجرعة وتناول جرعتك التالية في الموعد المعتاد. ثم استمر في تناول كبسولاتك في مواعيد منتظمة كالمعتاد.

لا تتناول جرعة مضاعفة لتعويض جرعة منسية.

 

التوقف عن تناول برافتوفي

من المهم تناول برافتوفي طوال الفترة التي يحددها طبيبك. لا تغير جرعتك أو تتوقف عن تناول هذا الدواء إلا إذا أخبرك طبيبك بذلك.

 

إذا كانت لديك أي أسئلة إضافية حول استخدام هذا الدواء، فاسأل طبيبك أو الصيدلي أو الممرضة.

 

كما هو الحال بالنسبة لجميع الأدوية، يمكن أن يسبب هذا الدواء أعراضًا جانبية، إلا أنها لا تصيب الجميع.

 

الأعراض الجانبية الخطيرة

 

قد يسبب برافتوفي أعراضًا جانبية خطيرة. أخبر طبيبك فورًا إذا أصبت بأي من الأعراض الجانبية الخطيرة التالية، سواءً لأول مرة أو إذا تفاقمت (انظر أيضًا القسم ٢):

 

مشكلات في القلب: يمكن أن يؤثر برافتوفي عند تناوله مع بينيميتينيب على كفاءة عمل قلبك (انخفاض الكسر القذفي للبطين الأيسر)؛ ويمكن أن تتضمن العلامات والأعراض:

-                 الشعور بالدوار أو التعب أو الإغماء أو الدوخة

-                 ضيق التنفس

-                 الشعور بأن قلبك يخفق بشدة أو ضرباته متسارعة أو ينبض بشكل غير منتظم

-                 تورم اليدين أو الكاحلين أو الساقين أو القدمين

 

مشكلات في الكبد: عند تناول برافتوفي مع بينيميتينيب، يمكن أن يسبب ذلك مشكلات في الكبد. سيجري طبيبك فحوصات للدم للتحقق من وظائف الكبد قبل وأثناء العلاج ببرافتوفي. أخبر طبيبك إذا ظهرت عليك أي من العلامات والأعراض التالية لمشكلة في الكبد:

-                 اصفرار الجلد أو العينين

-                 بول داكن أو بني (لون الشاي)

-                 غثيان أو قيء

a. National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03

b. Dose modification of BRAFTOVI when administered with binimetinib or with cetuximab is not recommended for new primary cutaneous malignancies; ocular events other than uveitis, iritis, and iridocyclitis; interstitial lung disease/pneumonitis; creatine phosphokinase (CPK) elevation; rhabdomyolysis; and venous thromboembolism.

 

Refer to the binimetinib or cetuximab prescribing information for dose modifications for adverse reactions associated with each product, as appropriate.

 

Dose Modifications for Coadministration With Strong or Moderate CYP3A4 Inhibitors

Avoid coadministration of BRAFTOVI with strong or moderate CYP3A4 inhibitors. If coadministration is unavoidable, reduce the BRAFTOVI dose according to the recommendations in Table 4. After the inhibitor has been discontinued for 3 to 5 elimination half-lives, resume the BRAFTOVI dose that was taken prior to initiating the CYP3A4 inhibitor (see sections 4.5 and 5.2).

b.     Encorafenib exposure at the 75 mg QD BRAFTOVI dosage when coadministered with a strong CYP3A4 inhibitor is expected to be higher than at the 150 mg QD dosage in the absence of a CYP3A4 inhibitor and similar to exposure at the 225 mg QD dosage in the absence of a CYP3A4 inhibitor. Monitor patients closely for adverse reactions and use clinical judgement when using BRAFTOVI with strong CYP3A4 inhibitors at the 150 mg dose level.

 

Duration of treatment

Treatment should continue until the patient no longer derives benefit or the development of unacceptable toxicity.

 

Missed doses

Do not take a missed dose of BRAFTOVI within 12 hours of the next dose of BRAFTOVI.

 

Vomiting

Do not take an additional dose if vomiting occurs after BRAFTOVI administration but continue with the next scheduled dose.

 

Special populations

Elderly patients

Of the 690 patients with BRAF mutation-positive melanoma who received BRAFTOVI in combination with binimetinib across multiple clinical trials, 20% were aged 65 to 74 years and 8% were aged 75 years and older (see section 5.1).

Of the 216 patients with BRAF V600E mutation-positive metastatic CRC who received BRAFTOVI in combination with cetuximab, 62 (29%) were 65 years of age to up to 75 years of age, while 20 (9%) were 75 years of age and over (see  section 5.1).

Of the 98 patients with BRAF V600E mutation-positive metastatic NSCLC who received BRAFTOVI with binimetinib, 62 (63%) were 65 years of age and over and 20 (20%) were 75 years and over (see section 5.1).

No overall differences in the safety or effectiveness of BRAFTOVI plus binimetinib or BRAFTOVI plus cetuximab were observed in older patients as compared to younger patients.

 

Hepatic impairment

No BRAFTOVI dosage adjustment is recommended in patients with mild hepatic impairment (Child-Pugh Class A) (see section 5.2). A recommended dosage has not been established in patients with moderate (Child-Pugh Class B) or severe (Child-Pugh Class C) hepatic impairment.

 

Renal impairment

No BRAFTOVI dosage adjustment is recommended in patients with mild to moderate renal impairment (CLcr 30 to <90 mL/min) (see section 5.2). A recommended dosage has not been established in patients with severe renal impairment (CLcr <30 mL/min).

 

Paediatric population

The safety and effectiveness of BRAFTOVI have not been established in pediatric patients.

 

Method of administration
 

Braftovi is for oral use. BRAFTOVI may be taken with or without food. The concomitant administration of encorafenib with grapefruit juice should be avoided (see sections 4.5 and 5.2)


Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

New primary malignancies

 

New primary malignancies, cutaneous and non-cutaneous, have been observed in patients treated with BRAF inhibitors and can occur with BRAFTOVI.

 

Cutaneous malignancies

In COLUMBUS, cutaneous squamous cell carcinoma (cuSCC), including keratoacanthoma (KA), occurred in 2.6%, and basal cell carcinoma occurred in 1.6% of patients who received BRAFTOVI in combination with binimetinib. Median time to first occurrence of cuSCC/KA was 5.8 months (range 1 to 9 months) (see section 4.8).

For patients who received BRAFTOVI as a single agent, cuSCC/KA was reported in 8%, basal cell carcinoma in 1%, and a new primary melanoma in 5% of patients.

In BEACON CRC, cuSCC/KA occurred in 1.4% of patients with CRC, and a new primary melanoma occurred in 1.4% of patients who received BRAFTOVI in combination with cetuximab.

In PHAROS, cuSCC and skin papilloma, each occurred in 2% of patients who received BRAFTOVI in combination with binimetinib.

Perform dermatologic evaluations prior to initiating treatment, every 2 months during treatment, and for up to 6 months following discontinuation of treatment. Manage suspicious skin lesions with excision and dermatopathologic evaluation. Dose modification is not recommended for new primary cutaneous malignancies.

 

Non-cutaneous malignancies
Based on its mechanism of action, BRAFTOVI may promote malignancies associated with activation of RAS through mutation or other mechanisms (see section 4.4). Monitor patients receiving BRAFTOVI for signs and symptoms of non-cutaneous malignancies. Discontinue BRAFTOVI for RAS mutation-positive non-cutaneous malignancies (see section 4.2).

 

Tumor Promotion in BRAF Wild-Type Tumors

 

In vitro experiments have demonstrated paradoxical activation of MAP-kinase signaling and increased cell proliferation in BRAF wild-type cells, which are exposed to BRAF inhibitors. Confirm evidence of BRAF V600E or V600K mutation prior to initiating BRAFTOVI (see sections 4.1 and 4.2).

 

Cardiomyopathy

 

Cardiomyopathy, manifesting as left ventricular dysfunction associated with symptomatic or asymptomatic decreases in ejection fraction, has been reported in patients treated with BRAFTOVI in combination with binimetinib. In COLUMBUS, evidence of cardiomyopathy (decreased in LVEF below the institutional LLN with an absolute decreased in LVEF ≥10% below baseline as detected by echocardiography or MUGA) occurred in 7% of patients receiving BRAFTOVI plus binimetinib. Grade 3 left ventricular dysfunction occurred in 1.6% of patients. The median time to first occurrence of left ventricular dysfunction (any grade) in patients receiving BRAFTOVI in combination with binimetinib was 3.6 months (range 0 to 21 months). Cardiomyopathy resolved in 87% of patients receiving BRAFTOVI plus binimetinib.

In PHAROS, evidence of cardiomyopathy (decrease in LVEF below the institutional LLN with an absolute decrease in LVEF ≥10% below baseline as detected by echocardiography or MUGA) occurred in 11% of patients receiving BRAFTOVI in combination with binimetinib. Grade 3 left ventricular dysfunction occurred in 1% of patients. Cardiomyopathy resolved in 82% of patients receiving BRAFTOVI plus binimetinib.

Assess ejection fraction by echocardiogram or MUGA scan prior to initiating treatment, one month after initiating treatment, and every 2 to 3 months during treatment. The safety of BRAFTOVI in combination with binimetinib has not been established in patients with baseline ejection fraction that is either below 50% or below the institutional lower limit of normal (LLN). Patients with cardiovascular risk factors should be monitored closely when treated with BRAFTOVI.

Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction (see sections 4.2 and 4.8).

 

Hepatotoxicity

 

Hepatotoxicity can occur when BRAFTOVI is administered in combination with binimetinib. In COLUMBUS, the incidence of Grade 3 or 4 increases in liver function laboratory tests in patients receiving BRAFTOVI in combination with binimetinib was 6% for alanine aminotransferase (ALT), 2.6% for aspartate aminotransferase (AST), and 0.5% for alkaline phosphatase. In PHAROS, the incidence of Grade 3 or 4 increases in liver function laboratory tests in patients receiving BRAFTOVI in combination with binimetinib was 10% for AST, 9% for ALT, and 3.2% for alkaline phosphatase.

Monitor liver laboratory tests before initiation of BRAFTOVI, monthly during treatment, and as clinically indicated. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction (see sections 4.2 and 4.8).

 

 

Haemorrhage

 

In COLUMBUS, hemorrhage occurred in 19% of patients receiving BRAFTOVI in combination with binimetinib; Grade 3 or greater hemorrhage occurred in 3.2% of patients. The most frequent hemorrhagic events were gastrointestinal, including rectal hemorrhage (4.2%), hematochezia (3.1%), and hemorrhoidal hemorrhage (1%). Fatal intracranial hemorrhage in the setting of new or progressive brain metastases occurred in 1.6% of patients.

In BEACON CRC, hemorrhage occurred in 19% of patients receiving BRAFTOVI in combination with cetuximab; Grade 3 or higher hemorrhage occurred in 1.9% of patients, including fatal gastrointestinal hemorrhage in 0.5% of patients. The most frequent hemorrhagic events were epistaxis (6.9%), hematochezia  (2.3%), and rectal hemorrhage (2.3%).

In PHAROS, hemorrhage occurred in 12% of patients receiving BRAFTOVI in combination with binimetinib including fatal hemorrhage intracranial (1%); Grade 3 or 4 hemorrhage occurred in 4.1% of patients. The most frequent hemorrhagic events were anal hemorrhage and hemothorax (2% each).

Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction (see sections 4.2 and 4.8).

 

Uveitis

 

Uveitis, including iritis and iridocyclitis, has been reported in patients treated with BRAFTOVI in combination with binimetinib. In COLUMBUS, the incidence of uveitis among patients treated with BRAFTOVI in combination with binimetinib was 4%. In PHAROS, the incidence of uveitis among patients treated with BRAFTOVI in combination with binimetinib was 1%.

Assess for visual symptoms at each visit. Perform an ophthalmologic evaluation at regular intervals and for new or worsening visual disturbances, and to follow new or persistent ophthalmologic findings. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction (see sections 4.2 and 4.8).

 

QT prolongation

 

BRAFTOVI is associated with dose-dependent QTc interval prolongation in some patients (see section 5.2). In COLUMBUS, an increase in QTcF to >500 ms was measured in 0.5% (1/192) of patients who received BRAFTOVI in combination with binimetinib. In PHAROS, an increase in QTcF to >500 ms was measured in 2.1% (2/95) of patients who received BRAFTOVI in combination with binimetinib.

Monitor patients who already have or who are at significant risk of developing QTc prolongation, including patients with known long QT syndromes, clinically significant bradyarrhythmias, severe or uncontrolled heart failure and those taking other medicinal products associated with QT prolongation. Correct hypokalemia and hypomagnesemia prior to and during BRAFTOVI administration. Withhold, reduce dose, or permanently discontinue for QTc >500 ms (see sections 4.2 and 4.8).

 

Embryo-Fetal Toxicity

 

Based on its mechanism of action, BRAFTOVI can cause fetal harm when administered to a pregnant woman. Encorafenib produced embryo-fetal developmental changes in rats and rabbits and was an abortifacient in rabbits at doses greater than or equal to those resulting in exposures approximately 26 (in the rat) and 178 (in the rabbit) times the human exposure at the recommended dose of 450 mg, with no clear findings at lower doses.

Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use an effective, non-hormonal method of contraception since BRAFTOVI can render hormonal contraceptives ineffective, during treatment and for 2 weeks after the last dose of BRAFTOVI (see sections 4.6).

 

Risks Associated with BRAFTOVI as a Single Agent

 

BRAFTOVI when used as a single agent is associated with an increased risk of certain adverse reactions compared to when BRAFTOVI is used in combination with binimetinib. In COLUMBUS, Grades 3 or 4 dermatologic reactions occurred in 21% of patients treated with BRAFTOVI single agent compared to 2% of patients treated with BRAFTOVI in combination with binimetinib (see sections 4.4 and 4.8).

If binimetinib is temporarily interrupted or permanently discontinued, reduce the dose of BRAFTOVI as recommended (see section 4.2).

 

Risks Associated with Combination Treatment

 

BRAFTOVI is indicated for use as part of a regimen in combination with binimetinib or cetuximab. Refer to the prescribing information for binimetinib and cetuximab for additional risk information.

 


Effects of other medicinal products on BRAFTOVI

 

Strong or Moderate CYP3A4 Inhibitors

Coadministration of BRAFTOVI with a strong or moderate CYP3A4 inhibitor increases encorafenib plasma concentrations (see section 5.2) and may increase encorafenib adverse reactions. Avoid coadministration of BRAFTOVI with strong or moderate CYP3A4 inhibitors, including grapefruit juice. If coadministration is unavoidable, reduce the BRAFTOVI dose (see section 4.2).

 

Strong CYP3A4 Inducers

Coadministration of BRAFTOVI with a strong or moderate CYP3A4 inducer may decrease encorafenib plasma concentrations (see section 5.2) and may decrease encorafenib efficacy. Avoid coadministration of BRAFTOVI with strong or moderate CYP3A4 inducers.

 

Effects of BRAFTOVI on other medicinal products

 

Sensitive CYP3A4 substrates

BRAFTOVI is a strong CYP3A4 inducer at steady-state. Concomitant use of BRAFTOVI may decrease the plasma concentrations of CYP3A4 substrates (including hormonal contraceptives), (see section 5.2), which may reduce the efficacy of these substrates. Avoid the coadministration of BRAFTOVI with CYP3A4 substrates for which a decrease in plasma concentration may lead to reduced efficacy of the substrate. If the coadministration cannot be avoided, see the CYP3A4 substrate product labeling for recommendations.

 

OATP1B1, OATP1B3, or BCRP substrates

Coadministration of BRAFTOVI with OATP1B1, OATP1B3, or BCRP substrates can result in increased concentrations of the substrates, and may increase toxicity of these agents. When used in combination, monitor patients closely for signs and symptoms of increased exposure and consider adjusting the dose of these substrates (see section 5.2).

 

Drugs That Prolong the QT Interval

 

BRAFTOVI is associated with dose-dependent QTc interval prolongation (see sections 4.4 and 5.2). Avoid coadministration of BRAFTOVI with drugs known to prolong the QT/QTc interval.


Women of childbearing potential / Contraception in females

 

BRAFTOVI can cause fetal harm when administered to a pregnant woman.

 

Pregnancy Testing

Verify the pregnancy status of females of reproductive potential prior to initiating BRAFTOVI.

 

Contraception

Advise females of reproductive potential to use effective contraception during treatment with BRAFTOVI and for 2 weeks after the last dose. Counsel patients to use a non-hormonal method of contraception since BRAFTOVI has the potential to render hormonal contraceptives ineffective (see section 4.5).

 

Pregnancy

 

Risk Summary

Based on its mechanism of action, BRAFTOVI can cause fetal harm when administered to a pregnant woman (see section 5.2). There are no available clinical data on the use of BRAFTOVI during pregnancy. In animal reproduction studies, encorafenib produced embryo-fetal developmental changes in rats and rabbits and was an abortifacient in rabbits at doses greater than or equal to those resulting in exposures approximately 26 (in the rat) and 178 (in the rabbit) times the human exposure at the clinical dose of 450 mg, with no clear findings at lower doses (see Data). Advise pregnant women and females of reproductive potential of the potential risk to a fetus.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

 

Data

Animal Data

In reproductive toxicity studies, administration of encorafenib to rats during the period of organogenesis resulted in maternal toxicity, decreased fetal weights, and increased incidence of total skeletal variations at a dose of 20 mg/kg/day (approximately 26 times the human exposure based on area under the concentration-time curve [AUC] at the recommended clinical dose of 450 mg once daily). In pregnant rabbits, administration of encorafenib during the period of organogenesis resulted in maternal toxicity, decreased fetal body weights, increased incidence of total skeletal variations and increased post-implantation loss, including total loss of pregnancy at a dose of 75 mg/kg/day (approximately 178 times the human exposure based on AUC at the recommended clinical dose of 450 mg once daily). While formal placental transfer studies have not been performed, encorafenib exposure in the fetal plasma of both rats and rabbits was up to 1.7% and 0.8%, respectively, of maternal exposure.

 

Breast-feeding

 

Risk Summary

There are no data on the presence of encorafenib or its metabolites in human milk or the effects of encorafenib on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child from BRAFTOVI, advise women not to breastfeed during treatment with BRAFTOVI and for 2 weeks after the last dose.

 

Fertility

 

Based on findings in male rats at doses approximately 13 times the human exposure at the 450 mg clinical dose, use of BRAFTOVI may impact fertility in males  (see section 5.3).


Encorafenib has minor influence on the ability to drive or use machines. Visual disturbances have been reported in some patients treated with encorafenib during clinical studies. Patients should be advised not to drive or use machines if they experience visual disturbances or any other adverse reactions that may affect their ability to drive and use machines (see sections 4.4 and 4.8).


 

The following adverse reactions are described elsewhere in the labeling:

•        New Primary Malignancies (see section 4.4)

•        Tumor Promotion in BRAF Wild-Type Tumors (see section 4.4)

•        Cardiomyopathy (see section 4.4)

•        Hepatotoxicity (see section 4.4)

•        Risks Associated with BRAFTOVI as a Single Agent (see section 4.4)

•        Risks Associated with Combination Treatment (see section 4.4)

 

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

 

BRAF V600E or V600K Mutation-Positive Unresectable or Metastatic Melanoma

The safety of BRAFTOVI in combination with binimetinib is described in 192 patients with BRAF V600 mutation-positive unresectable or metastatic melanoma who received BRAFTOVI (450 mg once daily) in combination with binimetinib (45 mg twice daily) in a randomized open-label, active-controlled trial (COLUMBUS).

The COLUMBUS trial (see section 5.1) excluded patients with a history of Gilbert’s syndrome, abnormal left ventricular ejection fraction, prolonged QTc (>480 ms), uncontrolled hypertension, and history or current evidence of retinal vein occlusion. The median duration of exposure was 11.8 months for patients treated with BRAFTOVI in combination with binimetinib and 6.2 months for patients treated with vemurafenib.

The most common (>25%) adverse reactions in patients receiving BRAFTOVI in combination with binimetinib were fatigue, nausea, vomiting, abdominal pain, and arthralgia.

Adverse reactions leading to dose interruptions of BRAFTOVI occurred in 30% of patients receiving BRAFTOVI in combination with binimetinib; the most common were nausea (7%), vomiting (7%), and pyrexia (4%). Adverse reactions leading to dose reductions of BRAFTOVI occurred in 14% of patients receiving BRAFTOVI in combination with binimetinib; the most common were arthralgia (2%), fatigue (2%), and nausea (2%). Five percent (5%) of patients receiving BRAFTOVI in combination with binimetinib experienced an adverse reaction that resulted in permanent discontinuation of BRAFTOVI; the most common were hemorrhage in 2% and headache in 1% of patients.

Table 5 and Table 6 present adverse drug reactions and laboratory abnormalities, respectively, identified in COLUMBUS. The COLUMBUS trial was not designed to demonstrate a statistically significant difference in adverse reaction rates for BRAFTOVI in combination with binimetinib, as compared to vemurafenib, for any specific adverse reaction listed in Table 5.

BRAFTOVI when used as a single agent increases the risk of certain adverse reactions compared to BRAFTOVI in combination with binimetinib. In patients receiving BRAFTOVI 300 mg orally once daily as a single agent, the following adverse reactions were observed at a higher rate (≥5%) compared to patients receiving BRAFTOVI in combination with binimetinib: palmar-plantar erythrodysesthesia syndrome (51% vs. 7%), hyperkeratosis (57% vs. 23%), dry skin (38% vs. 16%), erythema (16% vs. 7%), rash (41% vs. 22%), alopecia (56% vs. 14%), pruritus (31% vs. 13%), arthralgia (44% vs. 26%), myopathy (33% vs. 23%), back pain (15% vs. 9%), dysgeusia (13% vs. 6%), and acneiform dermatitis (8% vs. 3%).

Other clinically important adverse reactions occurring in <10% of patients who received BRAFTOVI in combination with binimetinib were:

Nervous system disorders: Facial paresis

Gastrointestinal disorders: Pancreatitis

Skin and subcutaneous tissue disorders: Panniculitis, Photosensitivity

BRAF V600E Mutation-Positive Metastatic Colorectal Cancer (CRC)

The safety of BRAFTOVI 300 mg once daily in combination with cetuximab (400 mg/m2 initial dose, followed by 250 mg/m2 weekly) was evaluated in 216 patients with BRAF V600E mutation-positive metastatic CRC in a randomized, open-label, active-controlled trial (BEACON CRC). The BEACON CRC trial (see section 5.1) excluded patients with a history of Gilbert’s syndrome, abnormal left ventricular ejection fraction, prolonged QTc (>480 ms), uncontrolled hypertension, and history or current evidence of retinal vein occlusion. The median duration of exposure was 4.4 months for patients treated with BRAFTOVI in combination with cetuximab and 1.6 months for patients treated with either irinotecan or infusional 5-fluorouracil (5-FU)/folinic acid (FA)/irinotecan (FOLFIRI) in combination with cetuximab.

The most common (≥25%) adverse reactions in patients receiving BRAFTOVI in combination with cetuximab were fatigue, nausea, diarrhea, dermatitis acneiform, abdominal pain, decreased appetite, arthralgia, and rash.

Adverse reactions leading to dose interruptions of BRAFTOVI occurred in 33% of patients receiving BRAFTOVI in combination with cetuximab; the most common were vomiting (4%), fatigue (4%), nausea (4%), pyrexia (3%), and diarrhea (3%). Adverse reactions leading to dose reductions of BRAFTOVI occurred in 9% of patients receiving BRAFTOVI in combination with cetuximab; the most common were fatigue (2%), arthralgia (2%), and peripheral neuropathy (2%). Ten percent (10%) of patients receiving BRAFTOVI in combination with cetuximab experienced an adverse reaction that resulted in permanent discontinuation of BRAFTOVI. None of the adverse reactions leading to permanent discontinuation of BRAFTOVI occurred in more than one patient (>0.5%).

Table 7 and Table 8 present adverse drug reactions and laboratory abnormalities, respectively, identified in BEACON CRC.

BRAF V600E Mutation-Positive Metastatic Non-Small Cell Lung Cancer (NSCLC)

The safety of BRAFTOVI in combination with binimetinib was evaluated in 98 patients with BRAF V600E mutation-positive metastatic NSCLC who received BRAFTOVI (450 mg once daily) in combination with binimetinib (45 mg twice daily) in an open-label, single-arm trial (PHAROS).

The PHAROS trial (see section 5.1) excluded patients with abnormal left ventricular ejection fraction, prolonged QTc (>480 ms), uncontrolled hypertension, and history or current evidence of retinal vein occlusion. The median duration of treatment for BRAFTOVI and binimetinib was 9.2 and 8.4 months, respectively.

The most common (≥25%) adverse reactions in patients receiving BRAFTOVI were fatigue, nausea, diarrhea, musculoskeletal pain, vomiting, abdominal pain, visual impairment, constipation, dyspnea, rash, and cough.

Adverse reactions leading to dose interruptions of BRAFTOVI occurred in 59% of patients receiving BRAFTOVI; the most common (≥5%) were diarrhea (17%); nausea (13%); musculoskeletal pain, fatigue (8% each); AST increased (7%); ALT increased, anemia, hemorrhage, vomiting (6% each); and acute kidney injury (5%). Adverse reactions leading to dose reductions of BRAFTOVI occurred in 30% of patients receiving BRAFTOVI; the most common (≥5%) were diarrhea, nausea (8% each); AST increased and fatigue (5% each). A total of 16% of patients receiving BRAFTOVI experienced an adverse reaction that resulted in permanent discontinuation of BRAFTOVI; the most common (≥2%) were diarrhea, musculoskeletal pain (3.1% each); fatigue, rash, nausea, visual impairment, and vomiting (2% each). None of the other adverse reactions leading to permanent discontinuation of BRAFTOVI occurred in more than 1 patient.

Serious adverse reactions occurred in 38% of patients who received BRAFTOVI in combination with binimetinib. Serious adverse reactions occurring in ≥2% of patients were hemorrhage (6%); diarrhea (4.1%); anemia, dyspnea, pneumonia (3.1% each); arrhythmia, device related infection, edema, myocardial infarction, and pleural effusion (2% each). Fatal adverse reactions occurred in 2% of patients who received BRAFTOVI (450 mg once daily) in combination with binimetinib, including intracranial hemorrhage and myocardial infarction (1% each).

Since encorafenib is 86% bound to plasma proteins, hemodialysis is likely to be ineffective in the treatment of overdose with BRAFTOVI.


Pharmacotherapeutic group: antineoplastic agents, protein kinase inhibitors, ATC code: L01EC03

 

Mechanism of action

 

Encorafenib is a kinase inhibitor that targets BRAF V600E, as well as wild-type BRAF and CRAF in in vitro cell-free assays with IC50 values of 0.35, 0.47, and 0.3 nM, respectively. Mutations in the BRAF gene, such as BRAF V600E, can result in constitutively activated BRAF kinases that may stimulate tumor cell growth. Encorafenib was also able to bind to other kinases in vitro including JNK1, JNK2, JNK3, LIMK1, LIMK2, MEK4, and STK36 and reduce ligand binding to these kinases at clinically achievable concentrations (≤0.9 µM).

Encorafenib inhibited in vitro growth of tumor cell lines expressing BRAF V600 E, D, and K mutations. In mice implanted with tumor cells expressing BRAF V600E, encorafenib induced tumor regressions associated with RAF/MEK/ERK pathway suppression.

Encorafenib and binimetinib target two different kinases in the RAS/RAF/MEK/ERK pathway. Compared with either drug alone, coadministration of encorafenib and binimetinib resulted in greater anti-proliferative activity in vitro in BRAF mutation-positive cell lines and greater anti-tumor activity with respect to tumor growth inhibition in BRAF V600E mutant human melanoma xenograft studies in mice. Additionally, the combination of encorafenib and binimetinib delayed the emergence of resistance in BRAF V600E mutant human melanoma xenografts in mice compared to either drug alone. In a BRAF V600E mutant NSCLC patient-derived xenograft model in mice, coadministration of encorafenib and binimetinib resulted in greater anti-tumor activity compared to binimetinib alone, with respect to tumor growth inhibition. Increased tumor growth delay after dosing cessation was also observed with the coadmnistration compared to either drug alone.

In the setting of BRAF-mutant CRC, induction of EGFR-mediated MAPK pathway activation has been identified as a mechanism of resistance to BRAF inhibitors. Combinations of a BRAF inhibitor and agents targeting EGFR have been shown to overcome this resistance mechanism in nonclinical models. Coadministration of encorafenib and cetuximab had an anti-tumor effect greater than either drug alone, in a mouse model of colorectal cancer with mutated BRAF V600E.

 

Cardiac Electrophysiology

A dedicated study to evaluate the QT prolongation potential of BRAFTOVI has not been conducted. BRAFTOVI is associated with dose-dependent QTc interval prolongation. Based on a central tendency analysis of QTc in a study of adult patients with melanoma who received the recommended dose of BRAFTOVI in combination with binimetinib, the largest mean (90% CI) QTcF change from baseline (ΔQTcF) was 18 (14 to 22) ms (see section 4.4).

 

Clinical efficacy and safety

 

BRAF V600E or V600K Mutation-Positive Unresectable or Metastatic Melanoma

BRAFTOVI in combination with binimetinib was evaluated in a randomized, active-controlled, open-label, multicenter trial (COLUMBUS; NCT01909453). Eligible patients were required to have BRAF V600E or V600K mutation-positive unresectable or metastatic melanoma, as detected using the bioMerieux THxID™BRAF assay. Patients were permitted to have received immunotherapy in the adjuvant setting and one prior line of immunotherapy for unresectable locally advanced or metastatic disease. Prior use of BRAF inhibitors or MEK inhibitors was prohibited. Randomization was stratified by American Joint Committee on Cancer (AJCC) Stage (IIIB, IIIC, IVM1a or IVM1b, versus IVM1c), Eastern Cooperative Oncology Group (ECOG) performance status (0 versus 1), and prior immunotherapy for unresectable or metastatic disease (yes versus no).

Patients were randomized (1:1:1) to receive BRAFTOVI 450 mg once daily in combination with binimetinib 45 mg twice daily (BRAFTOVI in combination with binimetinib), BRAFTOVI 300 mg once daily, or vemurafenib 960 mg twice daily. Treatment continued until disease progression or unacceptable toxicity. Only the results of the approved dosing (BRAFTOVI 450 mg in combination with binimetinib 45 mg) are described below.

The major efficacy outcome measure was progression-free survival (PFS), as assessed by a blinded independent central review, to compare BRAFTOVI in combination with binimetinib with vemurafenib. Additional efficacy outcome measures included overall survival (OS), as well as objective response rate (ORR) and duration of response (DoR) which were assessed by central review.

A total of 577 patients were randomized, 192 to the BRAFTOVI in combination with binimetinib arm, 194 to the BRAFTOVI arm, and 191 to the vemurafenib arm. Of the 383 patients randomized to either the BRAFTOVI in combination with binimetinib or the vemurafenib arms, the median age was 56 years (20 to 89 years), 59% were male, 91% were White, and 72% had baseline ECOG performance status of 0. Ninety‑five percent (95%) had metastatic disease, 65% were Stage IVM1c, and 4% received prior CTLA-4, PD-1, or PD-L1 directed antibodies. Twenty-eight percent (28%) had elevated baseline serum lactate dehydrogenase (LDH), 45% had ≥3 organs with tumor involvement at baseline, and 3% had brain metastases. Based on centralized testing, 100% of patients’ tumors tested positive for BRAF mutations; BRAF V600E (88%), BRAF V600K (11%), or both (<1%).

BRAFTOVI in combination with binimetinib demonstrated a statistically significant improvement in PFS compared to vemurafenib. Efficacy results are summarized in Table 11 and Figure 1.

BRAF V600E Mutation-Positive Metastatic Colorectal Cancer (CRC)

 

BRAFTOVI in combination with cetuximab was evaluated in a randomized, active-controlled, open-label, multicenter trial (BEACON CRC; NCT02928224). Eligible patients were required to have BRAF V600E mutation-positive metastatic colorectal cancer (CRC), as detected using the Qiagen therascreen BRAF V600E RGQ polymerase chain reaction (PCR) Kit, with disease progression after 1 or 2 prior regimens. Other key eligibility criteria included absence of prior treatment with a RAF, MEK, or EGFR inhibitor, eligibility to receive cetuximab per local labeling with respect to tumor RAS status, and ECOG performance status (PS) 0-1. Randomization was stratified by Eastern Cooperative Oncology Group (ECOG) performance status (0 versus 1), prior use of irinotecan (yes versus no), and cetuximab product used (US‑licensed versus EU-approved).

Patients were randomized 1:1:1 to one of the following treatment arms:

·         BRAFTOVI 300 mg orally once daily in combination with cetuximab (BRAFTOVI/cetuximab arm)

·         BRAFTOVI 300 mg orally once daily in combination with binimetinib and cetuximab

·         Irinotecan with cetuximab or FOLFIRI with cetuximab (control arm)

The dosage of cetuximab in all patients was 400 mg/m2 intravenously for the first dose followed by 250 mg/m2 weekly.

Patients in the control arm received cetuximab with either irinotecan 180 mg/m2 intravenously on Days 1 and 15 of each 28‑day cycle or FOLFIRI intravenously (irinotecan 180 mg/m2 on Days 1 and 15; folinic acid 400 mg/m2 on Days 1 and 15; then fluorouracil 400 mg/m2 bolus on Days 1 and 15 followed by fluorouracil 2400 mg/m2/day by continuous infusion over 2 days).

Treatment continued until disease progression or unacceptable toxicity. Only the results of the approved regimen (BRAFTOVI in combination with cetuximab) are described below.

The major efficacy outcome measure was overall survival (OS). Additional efficacy outcome measures included progression-free survival (PFS), overall response rate (ORR), and duration of response (DoR) as assessed by blinded independent central review (BICR). OS and PFS were assessed in all randomized patients. ORR and DoR were assessed in the subset of the first 220 patients included in the randomized portion of the BRAFTOVI/cetuximab and control arm of the study.

A total of 220 patients were randomized to the BRAFTOVI/cetuximab arm and 221 to the control arm. Of these 441 patients, the median age was 61 years; 53% were female; 80% were White and 15% were Asian. Fifty percent (50%) had baseline ECOG performance status of 0; 66% received 1 prior therapy and 34% received 2; 93% received prior oxaliplatin and 52% received prior irinotecan.  

BRAFTOVI in combination with cetuximab demonstrated a statistically significant improvement in OS, ORR, and PFS compared to the active comparator. Efficacy results are summarized in Table 12 and Figure 2.

BRAF V600E Mutation-Positive Metastatic Non-Small Cell Lung Cancer

BRAFTOVI in combination with binimetinib was evaluated in an open-label, multicenter, single‑arm study in patients with BRAF V600E mutation-positive metastatic non-small cell lung cancer (NSCLC) (PHAROS; NCT03915951). Eligible patients had a diagnosis of histologically-confirmed metastatic NSCLC with BRAF V600E mutation that was treatment-naïve or had been previously treated with 1 prior line of systemic therapy in the metastatic setting (platinum-based chemotherapy and/or anti-PD-1/PD-L1 therapies), age 18 years or older, Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1, and measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Prior use of BRAF inhibitors or MEK inhibitors was not allowed.

Patients received BRAFTOVI 450 mg once daily and binimetinib 45 mg orally twice daily until disease progression or unacceptable toxicity. The major efficacy outcome measures were objective response rate (ORR) per RECIST v1.1 and duration of response (DoR) as assessed by independent review committee (IRC).

In the efficacy population, BRAF V600E mutation status was determined by prospective local testing using tumor tissue (78%) or blood (22%) specimens. Of the 98 patients with BRAF V600E mutation, 6 patients were enrolled into the trial based on testing of their tumor tissue specimens with the FoundationOne CDx tissue test. Of the remaining 92 patients enrolled based on local testing, 68 patients had their tumor tissue specimens retrospectively confirmed as having BRAF V600E positive status by the FoundationOne CDx tissue test. The remaining patients had either BRAF V600E negative status (n=5) or had unevaluable results (n=19) by the FoundationOne CDx tissue test. In addition, plasma samples from 81 out of 98 patients were retrospectively tested using the FoundationOne Liquid CDx assay. Of the 81 patients, 48 were confirmed positive for BRAF V600E, while 33 patients were BRAF V600E mutation negative by FoundationOne Liquid CDx assay. The remaining 17 samples had unevaluable results with FoundationOne Liquid CDx assay.

The efficacy population included 59 treatment-naïve patients and 39 previously-treated patients. Among these 98 patients, the median age was 70 years (range: 47 to 86); 53% female; 88% White, 7% Asian, 3% Black or African American, and 1% American Indian or Alaska Native; 99% were not Hispanic or Latino; 13% were current smokers and 57% were former smokers; 73% had ECOG PS of 1; and 97% had adenocarcinoma. All patients had metastatic disease, and 8% had brain metastases at baseline.

Efficacy results for patients with BRAF V600E mutation-positive metastatic NSCLC are summarized in Table 13.

The pharmacokinetics of encorafenib were studied in healthy subjects and patients with solid tumors, including advanced and unresectable or metastatic cutaneous melanoma harboring a BRAF V600E or V600K mutation, BRAF V600E mutation-positive metastatic CRC. After a single dose, systemic exposure of encorafenib was dose proportional over the dose range of 50 mg to 700 mg (0.1 to 1.6 times the maximum recommended dose of 450 mg). After once-daily dosing, systemic exposure of encorafenib was less than dose proportional over the dose range of 50 mg to 800 mg (0.1 to 1.8 times the maximum recommended dose of 450 mg). Steady-state was reached within 15 days, with exposure being 50% lower compared to Day 1; intersubject variability (CV%) of AUC ranged from 12% to 69%.

 

Absorption

 

The median Tmax of encorafenib is 2 hours. At least 86% of the dose is absorbed.

 

Effect of Food

Following administration of a single dose of BRAFTOVI 100 mg (0.2 times the maximum recommended dose of 450 mg) with a high-fat, high-calorie meal (consisting of approximately 150 calories from protein, 350 calories from carbohydrates, and 500 calories from fat) the mean maximum encorafenib concentration (Cmax) decreased by 36% and there was no effect on AUC.

 

Distribution

 

The geometric mean (CV%) of apparent volume of distribution is 164 L (70%). The protein binding of encorafenib is 86% in vitro. The blood-to-plasma concentration ratio is 0.58.

 

Elimination

 

The mean (CV%) terminal half-life (t1/2) of encorafenib is 3.5 hours (17%), and the apparent clearance is 14 L/h (54%) at day 1, increasing to 32 L/h (59%) at steady-state at the maximum recommended dose of 450 mg.

 

Metabolism

Encorafenib is primarily metabolized by CYP3A4 (83%) and to a lesser extent by CYP2C19 (16%) and CYP2D6 (1%).

 

Excretion

Following a single radiolabeled dose of 100 mg encorafenib, 47% (5% unchanged) of the administered dose was recovered in feces and 47% (2% unchanged) in urine.

 

Medicinal product interactions

 

Clinical Studies

 

CYP3A4 Inhibitors: Coadministration of posaconazole (strong CYP3A4 inhibitor) or diltiazem (moderate CYP3A4 inhibitor) increased AUC of encorafenib by 3- and 2-fold, respectively, and increased Cmax by 68% and 45%, respectively, after a single dose of 50 mg BRAFTOVI (0.1 times the maximum recommended dose of 450 mg).

 

Strong CYP3A4 Inducers: The effect of a strong CYP3A4 inducer on encorafenib exposure has not been studied (see section 4.5).

Moderate CYP3A4 Inducers: Repeat dose administration of BRAFTOVI 450 mg once daily and binimetinib 45 mg twice daily with modafinil, a moderate CYP3A4 inducer, decreased encorafenib steady-state AUC by 24% and Cmax by 20%, compared to BRAFTOVI alone.

 

Effect of encorafenib on CYP3A4 Substrates: Repeat dose administration of BRAFTOVI 450 mg once daily and binimetinib 45 mg twice daily with a single dose of midazolam 2 mg, a sensitive CYP3A4 substrate, decreased midazolam AUC by 82% and Cmax by 74% relative to midazolam 2 mg alone.

 

Effect of encorafenib on Other CYP Substrates: There was no clinically significant effect of repeat dose administration of BRAFTOVI 450 mg once daily and binimetinib 45 mg twice daily on the exposure of substrates of CYP1A2, CYP2B6, CYP2C9, CYP2C19, and CYP2D6.

Proton Pump Inhibitors: No clinically significant differences in encorafenib pharmacokinetics were observed when coadministered with rabeprazole.

 

Binimetinib: No clinically significant differences in the pharmacokinetics of binimetinib (UGT1A1 substrate) were observed when coadministered with BRAFTOVI (UGT1A1 inhibitor).

Cetuximab: No clinically significant differences in the pharmacokinetics of encorafenib or cetuximab were observed when the recommended BRAFTOVI dose of 300 mg was coadministered with cetuximab.

 

Transporters: Repeat dose administration of BRAFTOVI 450 mg once daily and binimetinib 45 mg twice daily with a single dose of rosuvastatin (a sensitive substrate for OATP1B1, OATP1B3, and BCRP) increased rosuvastatin Cmax by 2.7-fold and AUC by 1.6-fold.

 

In Vitro Studies

 

CYP/UGT Enzymes: Encorafenib is a reversible inhibitor of UGT1A1.

 

Transporters: Encorafenib is a substrate of P-glycoprotein (P-gp) but not of breast cancer resistance protein (BCRP), multidrug resistance-associated protein 2 (MRP2), organic anion transporting polypeptide (OATP1B1, OATP1B3) or organic cation transporter (OCT1) at clinically relevant plasma concentrations.

 

Encorafenib is an inhibitor of P-gp, BCRP, OCT2, organic anion transporter (OAT1, OAT3), OATP1B1, and OATP1B3, but not of OCT1 or MRP2 at clinically relevant plasma concentrations.

 

Special populations

 

No clinically significant differences in the pharmacokinetics of encorafenib were observed based on age (19 to 94 years), sex, body weight (34 to 168 kg), mild hepatic impairment (Child-Pugh Class A), and mild or moderate renal impairment (CLcr 30 to <90 mL/min). The effect of race or ethnicity, moderate or severe hepatic impairment (Child-Pugh Class B or C), and severe renal impairment (CLcr <30 mL/min) on encorafenib pharmacokinetics have not been studied.


Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity studies with encorafenib have not been conducted. Encorafenib was not genotoxic in studies evaluating reverse mutations in bacteria, chromosomal aberrations in mammalian cells, or micronuclei in bone marrow of rats.

No dedicated fertility studies were performed with encorafenib in animals. In a general toxicology study in rats, decreased testes and epididymis weights, tubular degeneration in testes, and oligospermia in epididymides were observed at doses approximately 13 times the human exposure at the 450 mg clinical dose based on AUC. No effects on reproductive organs were observed in either sex in any of the non-human primate toxicity studies.

 

Animal Toxicology and/or Pharmacology

Adverse histopathology findings of hyperplasia and hyperkeratosis occurred in the stomach of rats at encorafenib doses of 20 mg/kg/day (approximately 14 times the human exposure at the 450 mg clinical dose based on AUC) or greater, in both 4 and 13-week studies.
