Detailed Description

This is a Japanese Phase I/II, open-label, non-controlled study to evaluate the safety, tolerability, pharmacokinetic profile, and efficacy of the combination of GSK2118436 and GSK1120212 in subjects with BRAF V600E/K mutation positive advanced solid tumors (Phase I part) and BRAF V600E/K mutation positive cutaneous melanoma (Phase II part). Phase I part is designed to primarily assess the safety and tolerability of GSK2118436 and GSK1120212 combination therapy in subjects with BRAF V600E/K mutation positive advanced solid tumors. Six evaluable subjects will be enrolled into Phase I part and receive the combination therapy of GSK2118436 (150 mg, twice daily) and GSK1120212 (2 mg, once daily). A decision for starting Phase II part will be made by careful review based on available safety, tolerability and pharmacokinetic data in Phase I part. Phase II part is designed to primarily evaluate ORR of the combination as first-line therapy in subjects with unresectable (Stage IIIC) or metastatic (Stage IV) BRAF V600E/K mutation positive cutaneous melanoma. Subjects who have had prior systemic anti-cancer treatment in the advanced or metastatic setting will not be eligible for Phase II part although prior systemic treatment in the adjuvant setting will be allowed. Six evaluable subjects will be enrolled in Phase II part.

Oxygen binds to hemoglobin in red blood cells when moving through the lungs. A pulse oximeter uses two frequencies of light (red and infrared) to determine the percentage of hemoglobin in the blood that is saturated with oxygen,that is called as blood oxygen saturation or SpO2. Change from Baseline was calculated as the individual post-Baseline value (Days 8,15; Weeks 3 to 136 and post-treatment Visit) minus the Baseline value. The Baseline value is defined as the last pre-treatment value observed.	From Baseline until the post-treatment Visit (average of 1.38 year)

The change from Baseline was categorized as: any increase; no change; 0-<10 Decrease, 10-19 Decrease, >=20 Decrease, >=10 Decrease and >= lower limit of normal (LLN), >=10 Decrease and below LLN, >=20 Decrease and >=LLN and >=20 Decrease and below LLN. The worst-case during the on-therapy period was determined taking into account both scheduled and unscheduled assessments.	From Baseline until the post-treatment Visit (average of 1.38 years)
Phase II: Number of Participant With Confirmed Overall Response	Confirmed overall response (ORR) is defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. RECIST is a set of rules that define when tumors in cancer participants improve ("respond"), stay the same ("stabilize"), or worsen ("progress") during treatment. CR is defined as disappearance of all target lesions. PR is defined as at least a 30% decrease in the sum of the diameters of target lesions after treatment from Baseline (before study drug administration). ORR was assessed by investigator and blinded independent central review (BICR).

DBP was categorized as: G1 (Increase to >=80 to <90 mmHg), G2 (Increase to >=90 to <100 mmHg), and G3 (Increase to >=100 mmHg). The worst-case during the on-therapy period was determined taking into account both scheduled and unscheduled assessments. An increase is defined as an increase in the CTCAE grade relative to the Baseline grade. Participants with missing Baseline values were assumed to have a Baseline value of G0.	From Baseline until the post-treatment Visit (average of 1.38 years)
Phase II: Number of Participants With Worst-case On-therapy Change From Baseline in Heart Rate	Change from Baseline in heart rate is categorized as decrease to <60 bpm, change to normal or no change, and increase to >100 bpm relative to the Baseline value. Participants with a missing Baseline value are assumed to have a normal Baseline value. Participants were counted twice if the participant's heart rate value decreased to <60 bpm and increased to >100 bpm post-Baseline. The worst-case during the on-therapy period was determined taking into account both scheduled and unscheduled assessments.	From Baseline until the post-treatment Visit (average of 1.38 years)
Phase II: Number of Participants With Worst-case On-therapy Change From Baseline in Temperature	Change from Baseline in temperature is categorized as a decrease to <=35 degrees C, change to normal or no change as 35-38 degrees C, and increase to >=38 degrees C relative to the Baseline value. Participants with a missing Baseline value are assumed to have a normal Baseline value. Participants were counted twice if the participant temperature value decreased to <=35 degrees C and increased to >=38 degrees C post-Baseline. The worst-case during the on-therapy period was determined taking into account both scheduled and unscheduled assessments.	From Baseline until the post-treatment Visit (average of 1.38 years)
Phase II: Change From Baseline in Oxygen Saturation Measured Via Pulse Oxymetry at the Indicated Time Points	Oxygen saturation measures the capacity of blood to transport oxygen to other parts of the body. Oxygen binds to hemoglobin in red blood cells when moving through the lungs. A pulse oximeter uses two frequencies of light (red and infrared) to determine the percentage of hemoglobin in the blood that is saturated with oxygen, that is called as blood oxygen saturation, or SpO2. Change from Baseline was calculated as the individual post-Baseline value (Days 8 and 15; Weeks 3 to 132 and post-treatment Visit) minus the Baseline value. The Baseline value is defined as the last pre-treatment value observed.	From Baseline until the post-treatment Visit (average of 1.38 years)
Phase II: Change From Baseline in Weight at the Indicated Time Points	Mean change in body weight from baseline was determined. Change from Baseline was calculated as the individual post-Baseline value (Weeks 3 to 132 and post-treatment Visit) minus the Baseline value. The Baseline value is defined as the last pre-treatment value observed.	From Baseline until the post-treatment Visit (average of 1.38 years)
Phase II: Number of Participants With the Indicated Electrocardiogram Findings at the Indicated Time Points	Single 12-lead ECGs were performed at Baseline, Weeks 3 to 132 and post-treatment Visit. ECG findings were categorized as: normal, abnormal - CS, or abnormal - NCS, as determined by the investigator.	From Baseline until the post-treatment Visit (average of 1.38 years)
Phase II: Number of Participants With Worst-case On-therapy Change From Baseline in Left Ventricular Ejection Fraction as Assessed by Echocardiogram	Absolute change from Baseline in LVEF were summarized at each scheduled assessment time and in the worst-case post Baseline. Only the post Baseline assessments that used the same method (ECHO or MUGA) as the Baseline assessments were used to derive the change from Baseline. The change from Baseline was categorized as: any increase; no change; 0-<10 Decrease, 10-19 Decrease, >=20 Decrease, >=10 Decrease and >= LLN, >=10 Decrease and below LLN, >=20 Decrease and >=LLN and >=20 Decrease and below LLN. The worst-case during the on-therapy period was determined taking into account both scheduled and unscheduled assessments.	From Baseline until the post-treatment Visit (average of 1.38 years)
