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.
