Inclusion criteria

Key Inclusion Criteria: * Histologically confirmed diagnosis of cutaneous melanoma with metastases to the brain. * Presence of B-RAF proto-oncogene, V600 mutant (BRAFV600) mutation in tumor tissue previously determined by a local PCR or NGS-based assay at any time prior to Screening or by a central laboratory during Screening. * Must have at least 1 parenchymal brain lesion ≥ 0.5 cm and ≤ 4 cm, defined as a magnetic resonance imaging (MRI) contrast-enhancing lesion that may be accurately measured in at least 1 dimension. (Measurable intracranial lesions that have been previously irradiated and have not been shown to be progressing following irradiation should not be considered as target lesions). * Patients may have received the following prior therapies: 1.

Overall Survival: SLI Phase and Phase 2

Overall survival (OS) was defined as the time from date of the first dose of study treatment to the date of death due to any cause. If a death was not observed by the date of the analysis cutoff, OS was censored at the date of last contact. OS (months) = (date of death or censoring - date of first dose +1)/30.4375

Time frame: From date of first dose of study treatment to the earliest documented disease progression by investigator assessment, or death due to any cause, whichever occurs first in SLI (approximately up to 10.4 months) and Phase 2 (approximately up to 8.3 months)

Population: Data was not collected due to the premature termination of the study and consequent lack of meaningful data, data are not available and no analyses were performed.

Secondary

PFS for Global Tumor Assessment: SLI Phase and Phase 2

PFS was defined as the time from date of the first dose of study treatment to the earliest documented disease progression (PD) by Investigator assessment, or death due to any cause, whichever occurs first. PD: 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 (i.e., 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 at least 5 mm. Global tumor assessment consists of brain metastasis and extracranial lesions. If a participant did not had a PFS event at the time of the analysis cutoff or at the start of any new anticancer therapy, PFS was censored at the date of last adequate tumor assessment.

Time frame: From date of first dose of study treatment to the earliest documented disease progression by investigator assessment, or death due to any cause, whichever occurs first in SLI (approximately up to 10.4 months) and Phase 2 (approximately up to 8.3 months)

Population: The safety set included all participants who received at least 1 dose of any study drug. Here, 'Number Analyzed' signifies participants evaluable for specified rows. Data has been presented per participant as data was not summarized due to limited number of participants with events.

Progression Free Survival (PFS) for Brain Metastasis Based on mRECIST v1.1: SLI Phase and Phase 2

PFS was defined as the time from date of the first dose of study treatment to the earliest documented disease progression (PD) by Investigator assessment, or death due to any cause, whichever occurs first. PD: at least a 20% increase in the sum of diameters of target lesions, taking as 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 of at least 5 mm. If a participant did not had a PFS event at the time of the analysis cutoff or at the start of any new anticancer therapy, PFS was censored at the date of last adequate tumor assessment.

Time frame: From date of first dose of study treatment to the earliest documented disease progression by investigator assessment, or death due to any cause, whichever occurs first in SLI (approximately up to 10.4 months) and Phase 2 (approximately up to 8.3 months)

Time of Last PK Sample (Tlast) of Encorafenib and Its Metabolite LHY746: SLI Phase

In this outcome measure, time of last PK sample (Tlast) of encorafenib and its metabolite LHY746 at C1D1, and C1D15 were assessed. As outlined in the prespecified Statistical Analysis Plan for the study, since encorafenib was administered in continuous cycles, the pre-dose sample on Cycle 2 Day 1 was assumed to be at steady state and was interpolated as the concentration on 24 hours for encorafenib and LHY746 on Cycle 1 Day 15 during the analysis. In doing so, the reported Tlast values from the noncompartmental analysis (NCA) are 24 hours for encorafenib and LHY746.

Time frame: Cycle 1 Day 1: 0.5, 1.5, 3, 6 hours (hrs) post-dose; Cycle 1 Day 15: Pre-dose, 0.5, 1.5, 3, 6, 24 hrs post-dose
