FDA Approves Genentech’s Cotellic™ (Cobimetinib) in Combination With Zelboraf® (Vemurafenib) in Advanced Melanoma
- FDA approval underscores the important role of targeted medicines to help people with BRAF V600 mutation-positive advanced melanoma
- Pivotal coBRIM study showed the combination improved progression-free and overall survival compared to Zelboraf alone
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that the U.S. Food and Drug Administration (FDA) approved Cotellic™ (cobimetinib) for the treatment of people with BRAF V600E or V600K mutation-positive unresectable or metastatic melanoma in combination with Zelboraf ® (vemurafenib). Cotellic and Zelboraf are not used to treat melanoma with a normal BRAF gene. Cotellic is Genentech’s seventh new medicine approved by the FDA in the past five years.
“When used in combination, Cotellic and Zelboraf help delay disease progression and help people live significantly longer than with Zelboraf alone,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “With this approval, people with this type of deadly and aggressive skin cancer now have a new targeted option.”
Today’s FDA approval is based on results from the Phase III coBRIM study, which showed Cotellic plus Zelboraf reduced the risk of disease worsening or death (progression-free survival; PFS) by about half in people who received the combination (HR=0.56, 95 percent CI 0.45-0.70; p<0.001), with a median PFS of 12.3 months for Cotellic plus Zelboraf compared to 7.2 months with Zelboraf alone. An interim analysis also showed the combination of Cotellic and Zelboraf helped people live significantly longer (overall survival) than Zelboraf alone (HR=0.63, 95 percent CI 0.47-0.85; p=0.0019). The objective response rate (tumor shrinkage) was higher with Cotellic plus Zelboraf compared to Zelboraf alone (70 vs. 50 percent; p<0.001), as was the complete response rate (complete tumor shrinkage, 16 vs. 10 percent).
Possible serious side effects with Cotellic include risk of skin cancers, increased risk of bleeding, heart problems that can lead to inadequate pumping of the blood by the heart, rash, eye problems, abnormal liver test or liver injury, increased levels of an enzyme in the blood, and photosensitivity. The most common side effects of Cotellic include diarrhea, sunburn or sun sensitivity, nausea, fever and vomiting. Cotellic can also cause changes in blood test results.
The final overall survival analysis from the coBRIM study will be presented at the Society for Melanoma Research (SMR) 2015 International Congress held in San Francisco, California from November 18-21.
In September, the Committee for Medicinal Products for Human Use (CHMP) at the European Medicines Agency (EMA) issued a positive opinion for Roche’s marketing authorization application for Cotellic in the European Union. A decision from the European Commission is expected before the end of 2015. Cotellic was approved in Switzerland by Swissmedic in August 2015.
Cotellic will be available to people in the United States within two weeks. For those who qualify, Genentech plans to offer patient assistance programs for people taking Cotellic in combination with Zelboraf through Genentech Access Solutions. Doctors can contact Genentech Access Solutions at (888) 249-4918. More information is also available at http://www.Genentech-Access.
About the coBRIM study
CoBRIM is an international, randomized, double-blind, placebo-controlled Phase III study evaluating the safety and efficacy of 60 mg once daily of Cotellic plus 960 mg twice daily of Zelboraf compared to 960 mg twice daily of Zelboraf plus placebo. In the study, 495 patients with BRAF V600 mutation-positive unresectable locally advanced or metastatic melanoma (detected by the cobas® 4800 BRAF Mutation Test) and previously untreated for advanced disease were randomized to receive Zelboraf every day on a 28-day cycle plus either Cotellic or placebo on days 1-21. Treatment was continued until disease progression, unacceptable toxicity or withdrawal of consent. Investigator-assessed PFS is the primary endpoint. Secondary endpoints include PFS by independent review committee, overall response rate, objective survival, duration of response and other safety, pharmacokinetic and quality of life measures.
About Cotellic plus Zelboraf
Cotellic and Zelboraf are prescription medicines used in combination to treat melanoma that has spread to other parts of the body or cannot be removed by surgery, and that has a certain type of abnormal “BRAF” gene. Found in approximately half of melanomas, mutated BRAF causes abnormal signaling inside cancer cells leading to tumor growth. Zelboraf is designed to inhibit some mutated forms of BRAF and Cotellic is designed to inhibit some forms of MEK. Both BRAF and MEK are proteins in a cell signaling pathway that help control cell growth and survival. When used in combination, Cotellic and Zelboraf are thought to reduce cancer cell growth longer than with Zelboraf alone. A patient’s healthcare provider will perform a test to make sure Cotellic and Zelboraf are right for the patient. It is not known if Cotellic and Zelboraf are safe and effective in children under 18 years of age.
About advanced melanoma
Melanoma is less common, but more aggressive and deadlier than other forms of skin cancer. When melanoma is diagnosed early, it is generally a curable disease, but most people with advanced melanoma have a poor prognosis. The American Cancer Society estimates there will be nearly 74,000 new cases of melanoma and 10,000 melanoma deaths this year in the United States.
In recent years, there have been significant advances in treatment for advanced melanoma and people with the disease have more options. However, it continues to be a serious health issue with a high unmet need and a steadily increasing incidence over the past 30 years.
Cotellic is a prescription medicine used with Zelboraf for the treatment of patients with a type of skin cancer called melanoma that has spread to other parts of the body or cannot be removed by surgery, and has a certain type of abnormal BRAF gene. Cotellic is not used to treat melanoma with a normal BRAF gene. Cotellic was discovered by Exelixis Inc. and was developed by Genentech in collaboration with Exelixis. Cotellic is also being investigated in combination with several investigational medicines, including an immunotherapy, in several tumor types such as non-small cell lung cancer and colorectal cancer.
Zelboraf was the first prescription treatment for patients with a type of skin cancer called melanoma that has spread to other parts of the body or cannot be removed by surgery, and has a certain type of abnormal BRAF gene as detected by an FDA-approved test. Cotellic and Zelboraf are not used to treat melanoma with a normal BRAF gene. Zelboraf is now approved in more than 90 countries and has been used to treat more than 20,000 patients worldwide. Zelboraf was co-developed under a 2006 license and collaboration agreement between Roche and Plexxikon, now a member of the Daiichi Sankyo Group.
Cotellic Important Safety Information
Before taking Cotellic, patients should tell their doctor if they:
- have any previous or current skin problems other than melanoma
- have any medical conditions and/or are on any medications that increase your risk of bleeding
- have any heart problems
- have any eye problems
- have any liver problems
- have any muscle problems
- have any other medical conditions
- are pregnant or plan to become pregnant. Cotellic can harm an unborn baby.
- Patients who take Cotellic should use effective methods of birth control during treatment, for at least two weeks after stopping Cotellic, and for at least two months after stopping Zelboraf.
- Patients should talk to their healthcare provider about birth control methods that may be right for them.
- Patients should tell their healthcare provider right away if they become pregnant or think they are pregnant during treatment with Cotellic.
- are breastfeeding or plan to breastfeed. It is not known if Cotellic passes into breast milk, so patients should not breastfeed during treatment with Cotellic and for two weeks after the final dose. Patients should talk to their healthcare provider about the best way to feed their baby during this time.
Patients should tell their healthcare provider about all the medicines they take, including prescription and over-the-counter medicines, vitamins and herbal supplements because some types of medicines will make Cotellic more harmful or less effective. Patients should know the medicines they take and keep a list of them to show their healthcare provider and pharmacist when they get a new medicine.
Patients should avoid sunlight while taking Cotellic. Cotellic can make patients skin sensitive to sunlight and cause them to burn more easily and get severe sunburns. To help protect against sunburn:
- When patients go outside they should wear clothes that protect their skin, including their head, face, hands, arms and legs.
- Patients should use lip balm and a broad-spectrum sunscreen with SPF 30 or higher.
Cotellic may cause serious side effects, including:
- Risk of skin cancers. Cotellic may cause skin cancers (cutaneous squamous cell carcinoma, keratoacanthoma or basal cell carcinoma).
Patients must check their skin and tell their doctor right away about any skin changes, including:
- new wart
- skin sore or reddish bump that bleeds or does not heal
- change in size or color of a mole
A patient’s healthcare provider should check their skin before they start taking Cotellic and every two months while taking Cotellic. A patient’s healthcare provider may continue to check their skin for six months after they stop taking Cotellic.
- Increased risk of bleeding. Cotellic may cause bleeding, including blood in the urine, rectal bleeding, unusual or excessive vaginal bleeding, bleeding of the gums and bleeding within the brain (cerebral hemorrhage). A patient should tell their healthcare provider right away if they experience any of these symptoms:
- red or black stools that look like tar
- blood in the urine
- headache, dizziness or feeling weak
- abdominal pain
- unusual vaginal bleeding
- Heart problems that can lead to inadequate pumping of the blood by the heart. A patient’s healthcare provider should perform tests before the patient starts taking Cotellic and during a patient’s treatment with Cotellic to check the ability of the heart to pump blood. Signs and symptoms of a decrease in the amount of blood pumped include:
- persistent coughing or wheezing
- shortness of breath
- swelling of their ankles and feet
- increased heart rate
- Rash. Patients should tell their healthcare provider right away if they experience any of these symptoms:
- a rash that covers a large area of their body, blisters or peeling skin
- Eye problems. Patients should tell their healthcare provider right away if they experience any of these symptoms during treatment with Cotellic:
- blurred vision
- distorted vision
- partly missing vision
- any other vision changes
Some of these eye problems may be a result of something called “serous retinopathy” (a build-up of fluid under the retina of the eye). A patient’s healthcare provider should check their eyes if they notice any of the symptoms above.
- Abnormal liver test or liver injury. A patient’s healthcare provider should perform blood tests before the start taking Cotellic, and during treatment. A patient should tell their healthcare provider right away if you experience any of these symptoms:
- yellowing of their skin or the white of their eyes
- dark or brown (tea color) urine
- nausea or vomiting
- feeling tired or weak
- loss of appetite
- Increased levels of an enzyme in the blood. Creatine phosphokinase (CPK) is an enzyme that is primarily found in the muscle, heart and brain. Treatment with Cotellic may increase the level of this enzyme in your blood and be a sign of muscle damage. A patient’s healthcare provider should perform a blood test before and during treatment. Increased blood levels of CPK can also be an indication of a serious condition caused by injury to the muscles (rhabdomyolysis). A patient should tell their healthcare provider right away if they experience any of these symptoms:
- muscle aches
- muscle spasms and weakness
- dark, reddish urine
- Photosensitivity. A patient’s skin may become more sensitive to sunlight while taking Cotellic. A patient should tell their healthcare provider if they notice any of the following symptoms:
- red, painful, itchy skin that is hot to touch
- sun rash
- skin irritation bumps or tiny papules
- thicken, dry, wrinkled skin
The most common side effects of Cotellic include:
- sunburn or sun sensitivity
A patient’s healthcare provider will take blood tests while they are taking Cotellic. The most common changes to blood tests include:
- increased blood levels of liver enzymes (GGT, ALT or AST)
- increased blood level of enzyme from muscle (creatine phosphokinase)
- decreased blood level of phosphate, sodium or potassium
- increased blood level of liver or bone enzyme (alkaline phosphatase)
- decreased blood level of a type of white blood cell (lymphocyte)
Patients should tell their healthcare provider if they have any side effect that bothers them or that does not go away.
These are not all the possible side effects of Cotellic. For more information about side effects, patients should ask their healthcare provider or pharmacist.
Patients should talk to their doctor for medical advice about side effects. Report side effects to FDA at (800) FDA-1088 or http://www.fda.gov/medwatch. Report side effects to Genentech at (888) 835-2555.

Zelboraf Important Safety Information
Zelboraf can cause serious side effects, including risk of cancers. Zelboraf may cause a type of skin cancer called cutaneous squamous cell carcinoma (cuSCC). New melanoma lesions have occurred in people who take Zelboraf. Zelboraf may also cause another type of cancer called non-cutaneous squamous cell carcinoma (SCC). Patients must talk with their healthcare provider about their risk for these cancers.
Patients must check their skin and tell their doctor right away about any skin changes, including:
- A new wart
- A skin sore or reddish bump that bleeds or does not heal
- A change in size or color of a mole
A patient’s doctor should check their skin before the patient starts taking Zelboraf, and every two months while the patient is taking Zelboraf, to look for any new skin cancers. Their doctor may continue to check the patient’s skin for six months after the patient stops taking Zelboraf.
A patient’s doctor should also check for cancers that may not occur on the skin. Patients should tell their doctor about any new symptoms they get while taking Zelboraf.
Before taking Zelboraf, patients should tell their doctor if they:
- Have any heart problems, including a condition called long QT syndrome
- Have liver or kidney problems
