Brief summary

This is a phase 1, multicenter, open-label, single-arm study to investigate the safety and tolerability of encorafenib 300 mg once daily (QD) monotherapy in adult Chinese participants with B-RAF Proto-oncogene, Serine/threonine Kinase V600E (BRAF V600E) mutant advanced solid tumors (unresectable metastatic melanoma or metastatic non-small cell lung cancer (NSCLC)), who are BRAF-inhibitor treatment-naïve and have failed the previous therapy(ies) in the metastatic setting or are not eligible to standard therapy. Participants will be eligible for the study based on identification of a BRAF V600E mutation in tumor tissue by a local National Medical Products Administration (NMPA) approved assay obtained prior to screening.

Dose Limiting Toxicities (DLTs) Experienced During Cycle 1

The primary endpoint was the number of patients experiencing dose limiting toxicity (DLT) occurring within the first 28 days of study treatment (Cycle 1). A DLT was defined as any adverse event or abnormal laboratory value assessed as unrelated to disease, disease progression, intercurrent illness or concomitant medications/therapies resulting in the inability to tolerate at least 75% dose intensity \[(administered dose in mg/planned dose in mg) × 100\] that satisfied at least one of the prespecified criteria.

Time frame: At the end of Cycle 1. Each cycle was 28 days.

Population: Dose-determining Set. The Dose-determining set consisted of all evaluable participants from the Safety Analysis Set who either achieved the minimum exposure requirement (i.e., encorafenib dose intensity of 75% in Cycle 1) and had sufficient safety evaluations.

Notable or Abnormal Changes From Baseline of 12-lead Electrocardiograms (ECGs)

12-lead ECGs were obtained using an internationally recognized 12-lead cardiograph. Clinically notable ECG values: QT \[millisecond (ms)\] and QT interval (ms) corrected for heart rate using Fridericia's formula (QTcF) intervals (ms): increase from baseline \> 30 ms; increase from baseline \> 60 ms, new \> 450 ms, new \> 480 ms, new \> 500 ms. Heart rate (beats/min): increase from baseline \> 25% to a value \> 100 bpm, decrease from baseline \> 25% and to a value \< 50 bpm. Number of participants with clinically notable values was reported.

Time frame: Screening (Days -28 to -1), Cycle 1 Day 8, 15 and 22, Day 1 of each subsequent even cycle, and the end of treatment visit, approximately up to 6 months. Each cycle was 28 days.
