CHMP positive opinion for EU approval of Tafinlar and Mekinist combination in BRAF V600 mutation-positive melanoma, the most aggressive type of skin cancer
FDA grants priority review for full approval of Tafinlar and Mekinist combination in BRAF V600 mutation-positive melanoma
Melanoma recommendations based on Phase III data showing more than 6 additional months of survival for Tafinlar/ Mekinist combination vs Tafinlar alone
Latest actions closely follow Breakthrough Therapy designation for Tafinlar and Mekinist in BRAF V600 mutation-positive NSCLC
Basel, July 24, 2015- Novartis today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion for the combination of Tafinlar® (dabrafenib) and Mekinist® (trametinib) for the treatment of adult patients with unresectable or metastatic melanoma with a BRAF V600 mutation. The Company also announced that the US Food and Drug Administration (FDA) has granted priority review for the same patient population.
"The CHMP positive opinion and FDA priority review of Tafinlar and Mekinist validate the importance of this targeted therapy combination for patients with the most serious form of skin cancer," said Bruno Strigini, President, Novartis Oncology. "This good news for the combination of Tafinlar and Mekinist in metastatic melanoma follows on the FDA's recent Breakthrough Therapy designation for the combination in BRAF V600 mutation-positive non-small cell lung cancer. We look forward to working with the US and EU regulatory authorities to help bring this targeted therapy combination to more patients who may benefit."
The CHMP positive opinion is based on results from the Phase III COMBI-d and COMBI-v studies. The COMBI-d study showed that the combination of Tafinlar and Mekinist achieved a statistically significant overall survival (OS) benefit compared to Tafinlar monotherapy (median of 25.1 months vs 18.7 months; Hazard Ratio [HR] 0.71 [95% Confidence Interval (CI), 0.55-0.92], p=0.011). In those who received Tafinlar in combination with Mekinist, OS was 74% at 1 year and 51% at 2 years versus 68% and 42% for those who received Tafinlar only, respectively. The COMBI-v study showed that the combination of Tafinlar and Mekinist achieved a statistically significant OS benefit compared to vemurafenib monotherapy (median for the combination not reached vs 17.2 months; HR 0.69 [95% CI, 0.53-0.89], p=0.005). In the COMBI-v study, the rate of OS at 1 year was 72% with the combination of Tafinlar and Mekinist and 65% for those receiving vemurafenib only. The safety results from these studies were consistent with the profile observed to date for the combination; no new safety concerns were observed,. The most common adverse reactions seen for combination therapy in both studies at >=20% include pyrexia, fatigue, nausea, headache, chills, diarrhea, rash, arthralgia, vomiting, hypertension, and cough. Adverse events or toxicities were generally manageable with appropriate intervention, as described in the product labelling submitted with the application.
The European Commission will review the CHMP recommendation and is expected to deliver its final decision within three months. The decision will be applicable to all 28 EU member states plus Iceland, Norway and Liechtenstein.
The US FDA granted Priority Review in metastatic melanoma for the supplemental New Drug Application (sNDA) for the combination of Tafinlar and Mekinist, which included data from the COMBI-d and COMBI-v studies. Since January 2014, the combination of Tafinlar and Mekinist has been approved for use in the US in patients with BRAF V600E/K mutation-positive unresectable or metastatic melanoma as detected by an FDA-approved test. The combination was approved through the FDA's Accelerated Approval program and reviewed under a Priority Review designation. The approval was contingent on the results of the COMBI-d study, which was designed to evaluate the clinical benefit of the combination in patients with unresectable or metastatic melanoma with a BRAF V600 mutation. A PDUFA date is in November 2015.
Metastatic melanoma is the most serious and life-threatening type of skin cancer and is associated with low survival rates with a five-year survival of about 20% for those with late-stage disease. There are about 200,000 new cases of melanoma diagnosed worldwide each year, approximately half of which have BRAF mutations,. Gene tests can determine whether a tumor has a BRAF mutation, and results can play a key role in prognosis and determining appropriate treatment.
The FDA Breakthrough Therapy designation in BRAF V600 mutation-positive non-small cell lung cancer (NSCLC) is based on interim analysis results from an ongoing single-arm, two-stage, Phase II trial investigating the Tafinlar and Mekinist combination in patients with metastatic NSCLC who had the BRAF V600E mutation and failed at least one line of chemotherapy. The data, which were presented at the 2015 Annual Meeting of the American Society of Clinical Oncology (ASCO), showed an overall response rate (ORR) of 63% [95% CI: 40.6, 81.2%] based on investigator assessment; the analysis by independent review was consistent with an ORR of 68% [95% CI: 45.1, 86.1%]. The most common adverse events (incidence >=20%) among patients included in this analysis were pyrexia, diarrhea, nausea, vomiting, decreased appetite, asthenia, cough, peripheral edema, and rash.
Breakthrough Therapy designation is intended to expedite the development and review of new medicines that treat serious or life-threatening conditions if the therapy has demonstrated substantial improvement over an available therapy on at least one clinically significant endpoint. The designation includes all of the fast track program features, as well as more intensive FDA guidance. It is a distinct status from both Accelerated Approval and Priority Review, which can also be granted to the same drug if relevant criteria are met.
Tafinlar and Mekinist in combination for NSCLC is the sixth Breakthrough Therapy designation for Novartis, continuing the company's trajectory as a leader in developing innovative therapies to help treat diseases in which there remains significant unmet medical need.
About the COMBI-d Study COMBI-d is a pivotal Phase III, randomized, double-blinded study comparing the combination of the BRAF inhibitor, Tafinlar, and the MEK inhibitor, Mekinist, to single agent therapy with Tafinlar and placebo in patients with unresectable (Stage IIIC) or metastatic (Stage IV) BRAF V600E/K mutation-positive cutaneous melanoma. The study randomized 423 patients at investigative sites in Australia, Europe and North and South America. The primary endpoint of this study was investigator-assessed progression-free survival (PFS). Secondary endpoints included overall survival (OS), overall response rate (ORR), duration of response (DoR), and safety. There was no crossover between treatment arms.
Updated results from the COMBI-d study showed that the combination of Tafinlar and Mekinist achieved a statistically significant OS benefit compared to Tafinlar monotherapy (median of 25.1 months vs 18.7 months; HR 0.71 [95% CI, 0.55-0.92], p=0.011). In those who received the Tafinlar and Mekinist combination, OS was 74% at 1 year and 51% at 2 years versus 68% and 42% for those who received Tafinlar only, respectively. The analysis for the combination also showed median PFS of 11.0 months, ORR of 69%, and median DoR of 12.9 months. The safety results were consistent with the profile observed to date for the combination and consistent with the profile observed for Tafinlar monotherapy; no new safety concerns were observed. The most common adverse events (>=20%) in the combination arm were pyrexia, fatigue, nausea, headache, chills, diarrhea, rash, joint pain (arthralgia), hypertension, vomiting, cough, and peripheral edema. More patients had AEs leading to dose modifications in the combination arm compared to Tafinlar monotherapy. Increased incidence (57% vs 33%) and severity (grade 3, 7% (n=15) vs 2% (n=4)) of pyrexia occurred with combination treatment as compared to Tafinlar monotherapy. There was a lower incidence of cutaneous squamous cell carcinoma (cuSCC) including keratoacanthoma with the combination arm (3% (n=6)) compared to the Tafinlar monotherapy arm (10% (n=22)). Discontinuation of treatment due to adverse events occurred in 11% (n=24) vs 7% (n=14) of patients in the combination group and the monotherapy group, respectively.
About the COMBI-v Study COMBI-v was a two-arm, open-label, Phase III study comparing the combination of Tafinlar and Mekinist combination therapy with vemurafenib monotherapy in patients with BRAF V600 mutation-positive unresectable or metastatic melanoma. The primary endpoint of this study was OS.
Results from the COMBI-v study showed a 31% decrease in the risk of death for patients treated with Tafinlar and Mekinist combination therapy compared to vemurafenib monotherapy (HR 0.69 [95% CI, 0.53-0.89], p=0.005). At 12 months, the rate of OS was 72% for the combination of Tafinlar and Mekinist and 65% for vemurafenib monotherapy. The analysis for the combination also showed median PFS of 11.4 months, ORR of 64%, and median DoR of 13.8 months. The most frequent adverse events in the Tafinlar and Mekinist combination arm (>=30%) were pyrexia, nausea, diarrhea, and chills. More patients had AEs leading to dose modifications in the combination arm compared to the vemurafenib monotherapy arm. For the combination group compared to the vemurafenib group, there was a lower incidence of rash, 22% (n=76) vs 43% (n=149); photosensitivity reaction, 4% (n=13) vs 22% (n=78); hand-foot syndrome, 4% (n=14) vs 25% (n=87); skin papillomas, 2% (n=6) vs 23% (n=80); squamous-cell carcinomas and keratoacanthomas, 1% (n=5) vs 18% (n=63); and hyperkeratosis, 4% (n=15) vs 25% (n=86). Adverse events occurring more frequently in the combination arm compared with the vemurafenib arm included pyrexia, 53% (n=184) vs 21% (n=73), respectively, and bleeding events, 18% (n=62) vs 7% (n=25), respectively. Discontinuation of treatment due to adverse events was similar between the treatment groups: 13% (n=44) for the combination group compared to 12% (n=41) for the monotherapy group.
About Tafinlar and Mekinist Combination Combination use of Tafinlar and Mekinist in patients with unresectable or metastatic melanoma who have BRAF V600E/K mutation is approved in the US, Australia, Canada and additional countries.
Tafinlar and Mekinist target different kinases within the serine/threonine kinase family - BRAF and MEK1/2, respectively - in the RAS/RAF/MEK/ERK pathway, which is implicated in NSCLC and melanoma, among other cancers. When Tafinlar is used with Mekinist, the combination has been shown to slow tumor growth more effectively compared with either drug alone. The combination of Tafinlar and Mekinist is currently being investigated in an ongoing clinical trial program across a range of tumor types conducted in study centers worldwide.
In 2015, as part of its purchase of oncology products from GlaxoSmithKline, Novartis obtained the worldwide exclusive rights granted by Japan Tobacco Inc. (JT) to develop, manufacture, and commercialize trametinib. JT retains co-promotion rights in Japan.
Tafinlar and Mekinist are registered trademarks of Novartis Pharma AG or its affiliates. The safety and efficacy profile of the Tafinlar and Mekinist combination has not yet been established outside the approved indication.
Tafinlar and Mekinist are also indicated in more than 35 countries worldwide, including the US and EU, as single agents to treat patients with unresectable or metastatic melanoma with a BRAF V600 mutation.
Tafinlar and Mekinist are being investigated in combination as a potential treatment for metastatic BRAF V600E mutation-positive NSCLC. Tafinlar and Mekinist are not approved as monotherapies or in combination anywhere in the world to treat NSCLC.
Tafinlar and Mekinist Combination Important Safety Information for Metastatic Melanoma Tafinlar and Mekinist combination may cause serious side effects, such as:
When Tafinlar is used in combination with Mekinist, or when Tafinlar is administered as monotherapy, it can cause new cancers (both skin cancer and non-skin cancer). Patients should be advised to contact their doctor immediately for any new lesions, changes to existing lesions on their skin, or signs and symptoms of other malignancies.
Before taking Tafinlar in combination with Mekinist, doctors should test their patients for BRAF wild-type melanoma, as patients without BRAF mutation and with RAS mutation can be at risk of increased cell proliferation in the presence of a BRAF inhibitor.
When Tafinlar is used in combination with Mekinist, it can increase the incidence and severity of bleeding, and in some cases can lead to death. Patients should be advised to call their healthcare provider and get medical help right away if they have headaches, dizziness, or feel weak, cough up blood or blood clots, vomit blood or their vomit looks like "coffee grounds," have red or black stools that look like tar, or any unusual signs of bleeding.
Tafinlar, in combination with Mekinist, can cause blood clots in the arms or legs, which can travel to the lungs and can lead to death. Patients should be advised to get medical help right away if they have the following symptoms: chest pain, sudden shortness of breath or trouble breathing, pain in their legs with or without swelling, swelling in their arms or legs, or a cool or pale arm or leg.
Tafinlar in combination with Mekinist can cause heart problems, including heart failure. A patient's heart function should be checked before and during treatment. Patients should be advised to call their healthcare provider right away if they have any of the following signs and symptoms of a heart problem: feeling like their heart is pounding or racing, shortness of breath, swelling of their ankles and feet, or feeling lightheaded.
Tafinlar alone, or in combination with Mekinist, can cause severe eye problems that can lead to blindness. Patients should be advised to call their healthcare provider right away if they get these symptoms of eye problems: blurred vision, loss of vision, or other vision changes, seeing color dots, halo (seeing blurred outline around objects), eye pain, swelling, or redness.
Patients should notify their doctor if they experience any new or worsening symptoms of lung or breathing problems, including shortness of breath or cough.
Tafinlar alone or in combination with Mekinist can cause fever, which may be serious. When taking Tafinlar in combination with Mekinist, fever may happen more often or may be more severe. In some cases, chills or shaking chills, too much fluid loss (dehydration), low blood pressure, dizziness, or kidney problems may happen with the fever. Patients should be advised to call their healthcare provider right away if they get a fever above 38.5oC (101.3oF) while taking Tafinlar.
Rash is a common side effect of Tafinlar alone, or when used in combination with Mekinist. Tafinlar alone, or in combination with Mekinist, can also cause other skin reactions. In some cases these rashes and other skin reactions can be severe, and may need to be treated in a hospital. Patients should be advised to call their healthcare provider if they get any of the following symptoms: skin rash that bothers them or does not go away, acne, redness, swelling, peeling, or tenderness of hands or feet, skin redness.
Some people may develop high blood sugar or worsening diabetes during treatment with Tafinlar, alone or in combination with Mekinist. For patients who are diabetic, their healthcare provider should check their blood sugar levels closely during treatment. Their diabetes medicine may need to be changed. Patients should be advised to tell their healthcare provider if they have any of the following symptoms of severe high blood sugar: increased thirst or urinating more often than normal, or urinating an increased amount of urine.
Tafinlar may cause healthy red blood cells to break down too early in people with G6PD deficiency. This may lead to a type of anemia called hemolytic anemia where the body does not have enough healthy red blood cells. Patients should be advised to tell their healthcare provider if they have any of the following signs or symptoms of anemia or breakdown of red blood cells: yellow skin (jaundice), weakness or dizziness, or shortness of breath.
Tafinlar and Mekinist both can cause harm to an unborn baby when taken by a pregnant woman. Tafinlar can also render hormonal contraceptives ineffective.
The most common side effects of Tafinlar and Mekinist combination include fever, nausea, tiredness, rash, chills, diarrhea, headache, vomiting, hypertension, joint pain, peripheral edema and cough. The incidence and severity of fever is increased when Mekinist is used in combination with Tafinlar.
Patients should tell their doctor of any side effect that bothers them or does not go away. These are not all of the possible side effects of Tafinlar and Mekinist combination. For more information, patients should ask their doctor or pharmacist.
Patients should take Tafinlar and Mekinist combination exactly as their health care provider tells them. Patients should not change their dose or stop taking Tafinlar and Mekinist combination unless their health care provider advises them to. Mekinist should be taken only once daily (either in the morning or evening, at the same time as Tafinlar). The first and second dose of Tafinlar should be taken approximately 12 hours apart. Patients should take Tafinlar and Mekinist at least 1 hour before or 2 hours after a meal. Do not take a missed dose of Tafinlar within 6 hours of the next dose of Tafinlar. Do not open, crush, or break Tafinlar capsules. Do not take a missed dose of Mekinist within 12 hours of the next dose of Mekinist.
