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.
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.

| Cohort A1: Durvalumab (3 mg/kg) + Dabrafenib +Trametinib | Experimental | Participants will receive intravenous (IV) dose of 3 milligrams per kilogram (mg/kg) durvalumab every 2 weeks (Q2W) from Day 1 up to 12 months along with oral 150 mg dabrafenib capsule twice daily (BID) and oral 2 mg trametinib tablet once daily (QD) until confirmed disease progression (PD), initiation of alternate cancer therapy, unacceptable toxicity, withdrawal of consent, or other reasons to discontinue treatment. Post-durvalumab treatment period, participants who developed PD and meet the criteria for re-administration, will receive durvalumab 3 mg/kg up to an additional 12 months and continued the treatment of dabrafenib and trametinib. |

| Measure | Description | Time Frame |
|---|---|---|
| Percentage of Participants With Objective Response (OR) | Objective Response is defined as confirmed complete response (CR) or confirmed partial response (PR) based on Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1). A confirmed CR is defined as two CRs that were separated by at least 28 days. A confirmed PR is defined as two PRs or an un-confirmed PR and an un-confirmed CR that were separated by at least 28 days. A CR is defined as disappearance of all target and non-target lesions, normalization of tumor marker level and any pathological lymph nodes selected as target lesions must have a reduction in short axis to less than 10 mm. A PR is defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. |

| Number of Participants With Abnormal Electrocardiograms (ECGs) and Echocardiograms (ECHOs) Reported as TEAEs |
Number of participants with abnormal electrocardiograms (ECGs) and echocardiograms (ECHOs) reported as TEAEs are reported. |
| From first dose of study drug (Day 1) up to 90 days after the last dose (up to 4.5 years) |
| From the first dose of study drug until last participant completes 12 months of treatment (assessed up to 4.5 years) |
| Duration of Response (DOR) | Duration of response: Duration from first documentation of OR to first documented PD or death due to any cause, whichever occurs first. CR: disappearance of all target and non-target lesions, normalization of tumor marker level and any pathological lymph nodes selected as target lesions must have a reduction in short axis to less than 10 mm. PR: at least a 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum diameters. PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of >= 5 mm, taking as reference smallest sum of diameters since treatment started including baseline sum of diameters. | From the first dose of study drug until last participant completes 12 months of treatment (assessed up to 4.5 years) |
| Progression-free Survival (PFS) | Progression-free Survival is defined as duration from the start of treatment with study drug until the first documented PD or death, whichever comes first. PD: at least a 20% increase in the sum of diameters of target lesions and an absolute increase of >= 5 mm, taking as reference smallest sum of diameters since treatment started including baseline sum of diameters.

A PR is defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. A SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum of diameters while on study. | From the first dose of study drug until last participant completes 12 months of treatment (assessed up to 4.5 years) |
