Number of Participants With BRAF V600E Mutation-positive Melanoma With Overall Intracranial Response (OIR), as Assessed by the InvestigatorFrom the time of the Baseline assessment until disease progression or end of study treatment (average of 18.3 weeks)OIR is defined as the number of participants whose intracranial response was a confirmed complete response (CR) or partial response (PR) assessed by investigators using modified Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. CR is defined as disappearance of all lesions. PR is defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the Baseline sum of the diameters (e.g., percent change from Baseline). For the primary analysis, OIR was measured when all participants in both treatment arms had two post-Baseline disease assessments. Participants who had an intracranial response of not evaluable or a missing response were treated as non-responders. Confirmation assessments were to be performed no less than 4 weeks after the criteria for response were initially met and may have been performed at the next protocol scheduled assessment.

Outcome results

Primary

Number of Participants With BRAF V600E Mutation-positive Melanoma With Overall Intracranial Response (OIR), as Assessed by the Investigator

OIR is defined as the number of participants whose intracranial response was a confirmed complete response (CR) or partial response (PR) assessed by investigators using modified Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. CR is defined as disappearance of all lesions. PR is defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the Baseline sum of the diameters (e.g., percent change from Baseline). For the primary analysis, OIR was measured when all participants in both treatment arms had two post-Baseline disease assessments. Participants who had an intracranial response of not evaluable or a missing response were treated as non-responders. Confirmation assessments were to be performed no less than 4 weeks after the criteria for response were initially met and may have been performed at the next protocol scheduled assessment.

Time frame: From the time of the Baseline assessment until disease progression or end of study treatment (average of 18.3 weeks)

Number of Participants With Any Adverse Event (AE) or Serious Adverse Event (SAE)

An AE is any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, or is an event of possible drug-induced liver injury.

Number of Participants With a Worst-case on Therapy Change to Grade 3 and Grade 4, or With Any Grade Increase (AGI), From Baseline Grade for Clinical Chemistry Parameters

Clinical chemistry data were summarized at each scheduled assessment according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE, version 4.0). Grade refers to the severity of the toxicity. The CTCAE displays Grades 1 through 5 with unique clinical descriptions of severity for each toxicity based on this general guideline: Grade (G) 1, mild; Grade 2, moderate; Grade 3, severe; Grade 4, life threatening; Grade 5, death related to toxicity. Blood sample was collected for the assessment of glucose, potassium, magnesium, sodium, phosphorus, potassium. aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), creatinine, total bilirubin, albumin, amylase, cholesterol, creatine kinase, gamma glutamyl transferase (GGT), lipase, blood pH, and triglycerides.

Time frame: From Screening until the conclusion of the study (up to 103 weeks)

Number of Participants With V600E Mutation-positive Melanoma With a Best Overall Response (OR) of CR or PR, as Assessed by the Investigator

OR is defined as the number of participants achieving either a CR (the disappearance of all target lesions) or PR (at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the Baseline sum of the diameters \[e.g., percent change from Baseline\]) per modified RECIST, version 1.1. To determine the OR, the extracranial response was combined with the intracranial response. Confirmation assessments were to be performed no less than 4 weeks after the criteria for response were initially met and may have been performed at the next protocol-scheduled assessment. Participants who had an overall response of not evaluable or a missing response were treated as non-responders.

Time frame: From the time of the Baseline assessment until disease progression or end of study treatment (average of 24 weeks)

Number of Participants With V600K Mutation-positive Melanoma With OIR, as Assessed by the Investigator

OIR is defined as the number of participants whose intracranial response was a confirmed complete response (CR) or partial response (PF) assessed by investigators using modified Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. 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, taking as a reference, the Baseline sum of the diameters (e.g., percent change from Baseline). For the primary analysis, OIR was measured when all participants in both treatment arms had two post-Baseline disease assessments. Participants who had an intracranial response of not evaluable or a missing response were treated as non-responders. Confirmation assessments were to be performed no less than 4 weeks after the criteria for response were initially met and may have been performed at the next protocol scheduled assessment.

Number of Response Genetics Incorporated (RGI) Investigational Use Only (IUO) Assay Mutation Positive Participants and THxID BRAF Assay Mutation Positive Participants With the Indicated Best Intracranial Response

The BRAF screening assay determines the specific BRAF mutational status (V600 E and K) in participants with metastatic melanoma who may benefit from treatment with GSK2118436. Per RECIST, version 1.1, CR is defined as the disappearance of all lesions. PR is defined as a \>=30% decrease in the sum of the diameters of target lesions, taking as a reference, the Baseline (BL) sum of the diameters (e.g., percent change from BL). Stable disease is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). PD is defined as a \>=20% increase in the sum of the diameters of target lesions, taking as a reference, the smallest sum of diameters recorded since the treatment started (e.g., percent change from nadir \[smallest sum of diameters recorded since treatment start\]). In addition, the sum must have an absolute increase from nadir of 5 millimeters. Not evaluable: cannot be classified by a preceding definition.
