DRUG TRIALS SNAPSHOT SUMMARY:
What is the drug for?
MEKTOVI is a drug which is used with another drug, encorafenib, to treat a type of skin cancer called melanoma.
MEKTOVI is only to be used in patients who have melanoma with a specific abnormal gene (called a BRAF V600E or V600K mutation) that has spread to other parts of the body (advanced melanoma) or cannot be removed by surgery.

How is this drug used?
MEKTOVI is a tablet. Three tablets (total of 45 mg) are taken by mouth twice daily with encorafenib.
What are the benefits of this drug?
MEKTOVI plus encorafenib delays disease worsening. In addition, 63% of patients taking
MEKTOVI plus encorafenib experienced complete or partial shrinkage of their tumors.
MEKTOVI plus encorafenib experienced complete or partial shrinkage of their tumors.
Were there any differences in how well the drug worked in clinical trials among sex, race and age?
- Sex: MEKTOVI worked similarly in men and women.
- Race: The majority of patients were White. The number of patients in other races was limited; therefore, differences in how well the drug worked among races could not be determined.
- Age: MEKTOVI worked similarly in patients younger and older than 65 years of age.
What are the possible side effects?
MEKTOVI in combination with encorafenib may cause serious side effects including heart failure, blood clots, muscle, eye, and liver damage, bleeding and lung inflammation.
The most common side effects of treatment with MEKTOVI when given with encorafenib are fatigue, nausea, diarrhea, vomiting and abdominal pain.
Were there any differences in side effects among sex, race and age?
- Sex: The occurrence of side effects was similar in men and women.
- Race: The majority of patients were White. The number of patients in other races was limited; therefore, differences in side effects among races could not be determined.
- Age: The occurrence of side effects was similar in patients younger and older than 65 years of age.
WHO WAS IN THE STUDIES?
Who participated in the clinical trials?
The FDA approved MEKTOVI based primarily on evidence from one clinical trial (NCT01909453) of 383 patients with BRAF V600 mutation-positive melanoma that was advanced or could not be removed by surgery. The trial was conducted at 162 sites in Europe, North America, and various countries around the world.

How were the trials designed?
The benefits and side effects of MEKTOVI were evaluated in one clinical trial. Enrolled patients had melanoma with a certain type of abnormal gene (called BRAF V600E or V600K mutation) that spread to other parts of the body or that could not be removed by surgery.
All patients received either MEKTOVI together with encorafenib or vemurafenib (FDA approved drug to treat melanoma) twice daily. Both, patients and investigators new which treatment had been given. Treatment continued until disease progression or development of unacceptable side effects.
The benefit of MEKTOVI was assessed by measuring the length of time it took the disease to worsen in patients who received MEKTOVI given with encorafenib and comparing it to the time the disease took to worsen in patients treated with vemurafenib.
GLOSSARY
CLINICAL TRIAL: Voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments.
COMPARATOR: A previously available treatment or placebo used in clinical trials that is compared to the actual drug being tested.
EFFICACY: How well the drug achieves the desired response when it is taken as described in a controlled clinical setting, such as during a clinical trial.
PLACEBO: An inactive substance or “sugar pill” that looks the same as, and is given the same way as, an active drug or treatment being tested. The effects of the active drug or treatment are compared to the effects of the placebo.
SUBGROUP: A subset of the population studied in a clinical trial. Demographic subsets include sex, race, and age groups.
