=================
Brief Summary
-----------------
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).

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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Phase I: 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 beats per minute (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 year) | 
| Phase I: 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 celsius (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 I: Change From Baseline in Oxygen Saturation (SpO2) 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 8,15; 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) | 
| Phase I: 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 136 and post-treatment Visit) minus the Baseline value.

The worst-case during the on-therapy period was determined taking into account both scheduled and unscheduled assessments. Hematology parameters included: hemoglobin, lymphocytes, total neutrophils, platelet count, WBC counts, basophils, eosinophils, hematocrit, MCHC, MCH, MCV, monocytes and RBC count. | From Baseline until the post-treatment Visit (average of 1.38 years) | 
| Phase II: Number of Participants With the Indicated Urinalysis Results | Urine samples were collected for urine dipstick analysis at Baseline and at the post-treatment Visit. The number of participants with negative (absence) and positive (presence: trace, 1+, 2+, 3+, 4+ or 5+) results for UOB, UGLU, UKET, UP and UUBIL were summarized. 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 Worst-case On-therapy Change From Baseline in ECOG Perormance Status | The ECOG pef status 5-point scale is used to assess how a participant's disease is progressing, to assess how the disease affects the daily living abilities of the par. and to determine appropriate treatment and prognosis: G0, fully active, able to carry on all pre-disease pef without restriction. G1, restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, example, light house work, office work. G2, ambulatory and capable of all selfcare, but unable to carry out any work activities; up and about >50% of waking hrs. G3, capable of only limited selfcare; confined to bed or chair >50% of waking hrs. G4, completely disabled; cannot carry on any selfcare; totally confined to bed or chair. G5, dead. The worst-case during the on-therapy period was determined taking into account both scheduled and unscheduled assessments. Number of par. who improved, had no change, or deteriorated in pef status from BL is summarized. | From Baseline until the post-treatment Visit (average of 1.38 years) | 
| Phase II: Number of Participants With Worst-case On-therapy Increase From Baseline in Systolic and Diastolic Blood Pressure to Grade 2 or Grade 3 | SBP and DBP values were graded using (NCI CTCAE version 4.0). SBP was categorized as: G1 (Increase to >=120 to 140 mmHg), G2 (Increase to >=140 to <160 mmHg), and G3 (Increase to >=160 mmHg). 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) |
