Best overall response is defined as complete response (CR: the disappearance of all target lesions. Any pathological lymph nodes must be \<10 millimeters \[mm\] in the short axis.) or partial reponse (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 \[e.g., percent change from Baseline\]). Participants with unknown or missing responses were considered as non-responders. To be assigned a status of PR or CR, a confirmatory disease assessment should have been performed no less than 28 days after the criteria for response were first met. Response was evaluated by an investigator as per Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1.

PFS is defined as the interval between the date of randomization and the earliest date of PD or death due to any cause. PD was based on radiographic or photographic evidence, and assessments were made by the investigator according to RECIST, version 1.1. PD is defined as at least 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, where nadir is defined as the smallest sum of diameters recorded since treatment start). In addition, the sum must have an absolute increase from nadir of 5 mm. Participants who received anti-cancer therapy prior to the date of documented events, were censored at the last adequate assessment prior to the initiation of therapy. If the participant did not had a documented date of events, PFS and survival were censored at the date of the last adequate assessment.

Participants with unknown or missing response were considered as non-responders. To be assigned a status of PR or CR, a confirmatory disease assessment should have been performed no less than 28 days after the criteria for response were first met. Response was evaluated by an investigator as per Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1.

p-ERK and p-AKT, biomarkers in tumor biopsies, were assessed for participants with BRAF mutant colorectal cancer. The H-score, which is a composite score that comprises intensity and percentage of staining, is a method of assessing the amount of protein or phospho-protein present in a biopsy sample. The score is obtained by the formula: (3 \* percentage of strongly staining nuclei) + (2 \* percentage of moderately staining nuclei) + (percentage of weakly staining nuclei). The H-score ranges from 0 to 300, with a score of 0 representing the absence of any of the target protein and an H-score of 300 representing maximum staining and intensity of the target protein.

For dabrafenib, population CL/F is defined as inducible and non-inducible CL/F. As dabrafenib induces its own metabolism, total oral clearance at steady state includes a non-induced (Day 1) component and an induced component, as estimated by a population PK model.

Summary
Brief summary
This was an open-label, dose escalation study to investigate the safety, pharmacokinetics, pharmacodynamics and clinical activity of GSK2118436 and GSK1120212 in combination. This study was designed in four parts. In Part A, the effect of repeat doses of GSK1120212 on the pharmacokinetics of single dose GSK2118436 was investigated prior to evaluating combination regimens. In Part B, the range of tolerated dose combinations was identified using a dose-escalation procedure. In Part C, different dose combinations of GSK2118436 and GSK1120212 were evaluated, based on results from the dose escalation cohorts. In Part D, the pharmacokinetics and safety of GSK2118436 administered as HPMC capsules alone and in combination with GSK1120212 was evaluated.
