Overview
Brief Summary
The purpose of this study is to determine the maximum tolerated dose and characterize the safety profile of durvalumab (MEDI4736) in combination with dabrafenib and trametinib or with trametinib alone in participants with metastatic or unresectable melanoma with BRAF-mutation positive or wild-type (WT) BRAF, respectively.
Detailed Description
This is a multicenter, open-label study with a dose escalation phase followed by an expansion phase of durvalumab administered in combination with dabrafenib and trametinib or with trametinib alone in participants with BRAF V600 mutation-positive and WT unresectable or metastatic melanoma, respectively.
