The composite rate of pyrexia related events was calculated as the total number of participants experiencing at least one of the three components of the composite endpoint (i.e., grade 3/4 pyrexia, hospitalization due to pyrexia, or permanent treatment discontinuation due to pyrexia), divided by the total number of participants treated in the study and multiplied by 100. Pyrexia is defined as fever ≥ 38 °C.

Pyrexia events were graded by the investigator using Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03 as Grade 1 (mild), Grade 2 (moderate), Grade 3 (severe), Grade 4 (Life-threatening) and Grade 5 (Death)

All subjects who received at least one dose of any study treatment

RFS is defined as the time from the date of first dose of the study treatment to the date of the first documented disease recurrence or death due to any cause whichever comes first. Treatment emergent malignancies other than second melanomas were not considered as events.

RFS rate is the estimated percent probability that a patient will remain event-free up to the specified time point. RFS rate was obtained from the Kaplan-Meier survival estimates. RFS was censored if no RFS event was observed before the first to occur between: (i) the analysis cut-off date, and (ii) the date when a new anti-cancer therapy is started. The censoring date was the date of the last adequate tumor assessment prior to data cut-off date/start of new anti-cancer therapy date.

All subjects who received at least one dose of any study treatment

OS is defined as the time from date of the first dose of study medication to date of death due to any cause, whichever comes first. If a patient was not known to have died, then OS rate is the estimated probability that a patient will remain event-free up to the specified time point. OS rate was obtained from the Kaplan-Meier survival estimates. OS was censored at the last contact date when the patient was known to be alive (on or before the cut-off date).

All subjects who received at least one dose of any study treatment

Percentage of patients who experienced pyrexia and required intervention including hospitalizations, concomitant medications, and study treatment modifications (dose reductions, permanent discontinuations and/or interruptions) due to pyrexia. Pyrexia is defined as fever ≥ 38 °C

All subjects who received at least one dose of any study treatment

Percentage of participants who permanently discontinued treatment due to any AE during treatment. An AE is any untoward medical occurrence (e.g., any unfavorable and unintended sign, symptom or disease) in a subject or clinical investigation subject after providing written informed consent for participation in the study.

The FACT-M is a questionnaire that assesses participant health-related quality of life. It includes a melanoma specific (FACT-M MS) subscale that consists in 16 items related to signs, symptoms, physical/social activities most relevant to participants with advanced-stage melanoma. Each item ranges from 0 (not at all) to 4 (very much). FACT-M MS score ranges from 0 to 64, with higher score indicating better quality of life. If a patient discontinued the study treatment at Month 1 or Month 2, then the follow-up assessments started at Month 3 follow-up and continued until Month 24 follow-up or at withdrawal, lost to follow-up, death, or end of study. If a patient discontinued the study treatment from Month 3 through Month 5, the follow-up assessments started at Month 6 follow-up. If a patient discontinued from Month 6 through Month 11, the follow-up assessments started from Month 12 follow-up. For patients who completed treatment, the follow-up assessments started from Month 15 follow-up

All subjects who received at least one dose of any study treatment. Number analyzed represents participants with data available at the specified data points

On-treatment deaths were collected from date of first administration of study treatment to 30 days after date of last administration of any study treatment (dabrafenib or trametinib).

Post-treatment follow-up deaths were collected after the on-treatment period. All deaths refer to the sum of on-treatment and post-treatment follow-up deaths

All subjects who received at least one dose of any study treatment.
