Overview
Brief Summary
BRF113710 is a Phase II, single-arm, open-label study to assess the efficacy, safety, and tolerability of GSK2118436 administered twice daily as a single agent in subjects with BRAF mutant metastatic melanoma. Subjects will receive 150 mg of GSK2118436 twice daily and continue on treatment until disease progression, death, or unacceptable adverse event.

- •Women of child-bearing potential must have a negative pregnancy test within 14 days prior to the first dose of study treatment.
- •Women with reproductive potential must be willing to practice acceptable methods of birth control during the study and for up to 4 weeks after the last dose of study medication.
- •Men with reproductive potential must be willing to practice acceptable methods of birth control during the study and for up to 16 weeks after the last dose of study medication.

Exclusion Criteria
- •Previous treatment with a BRAF or MEK inhibitor.
- •Cancer therapy (chemotherapy with delayed toxicity, radiation therapy, immunotherapy, biologic therapy, or major surgery) within the last 3 weeks; chemotherapy regimens without delayed toxicity within the last 2 weeks; or use of any investigational anti-cancer or other drug within 28 days or 5 half-lives, whichever is longer, preceding the first dose of GSK
- •A history of known Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), or Hepatitis C Virus (HCV) infection.
- •History or evidence of brain metastases on MRI or head CT if MRI is not able to be performed.
- •History of other malignancy. Subjects who have been disease-free for 5 years, or subjects with a history of completely resected non-melanoma skin cancer or successfully treated in situ carcinoma are eligible.

Arms & Interventions
All patients
Subjects will receive 150 mg of GSK2118436 twice daily and continue on treatment until disease progression, death, or unacceptable adverse event.
Intervention: GSK2118436 (Drug)
Outcomes
Primary Outcomes
Number of Participants With a Best Overall Response of Confirmed Complete Response (CR) or Partial Response (PR) as Assessed by the Investigator for Participants Who Had a BRAF V600E Mutation
Time Frame: Up to 60 months
A participant was defined as a responder if he/she achieved either a CR (the disappearance of all target lesions. Any pathological lymph nodes must be \<10 millimeter (mm) in the short axis.) or PR (at least a 30 percent decrease in the sum of the diameters of target lesions, taking as a reference, the Baseline sum of the diameters \[e.g., percent change from Baseline\]). To be assigned a status of PR or CR, a confirmatory disease assessment was required at Week 12 if an initial response was seen at the Week 6 scan. Initial responses (CR/PR) that occured at Week 12 or later were required to be confirmed not less than 4 weeks and not more than 6 weeks after the criteria for response were first met. The analysis was performed on Primary efficacy Population which comprised of all participants who received at least one dose of GSK2118436 (All Treated Participants Population) and had a BRAF V600E mutation.
Secondary Outcomes
- Duration of Response as Assessed by the Investigator and an Independent Reviewer for Participants Who Had a BRAF V600E Mutation(Up to 60 months)

- Number of Participants With AEs and Serious Adverse Events (SAEs)(Up to 60 months)
- Number of Participants With Change From Baseline in Temperature and Pulse Rate(Up to 60 months)
- Progression-free Survival (PFS) as Assessed by the Investigator and an Independent Reviewer for Participants Who Had a BRAF V600E Mutation(Up to 60 months)
- Progression-free Survival (PFS) as Assessed by the Investigator and an Independent Reviewer for Participants Who Had a BRAF V600K Mutation(Up to 60 months)
- Overall Survival for Participants Who Had a BRAF V600E Mutation(Up to 60 months)
