Encorafenib hard capsule will be orally self-administered. A fixed-flat dose of 300 mg (4 x 75 mg) Per Oral (PO) encorafenib will be administered once-daily (QD).

Encorafenib

Li Zhang, MD

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.

Phase 1 Safety Study of Encorafenib in Chinese Patients With Advanced Metastatic BRAF V600E Mutant Solid Tumors

Multicenter, Open-label, Phase 1 Study Investigating the Safety and Tolerability of Encorafenib Monotherapy in BRAF V600E-mutated Chinese Patients With Advanced Metastatic Solid Tumors

Incidence, nature and severity of treatment emergent adverse events (TEAEs) graded as per National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 4.03, TEAEs leading to dose interruption, reduction and discontinuation, treatment-emergent serious adverse events (SAEs) and deaths will be reported.

Clinically notable shift from baseline in blood hematology parameters data \[Hemoglobin (Low/High); Leukocytes (Low/ High); Neutrophils (Low); Platelets (Low/High); Lymphocytes (Low/High)\] will be graded using NCI CTCAE Version 4.03. Clinically notable shift is defined as a worsening from baseline by at least 2 grades, or to grade 3 or above. Number of participants with at least one clinically notable shift during study will be reported.

Clinically notable shift from baseline in blood clinical chemistry parameter values \[Phosphate (Low); Alanine Aminotransferase (High); Albumin (Low); Alkaline Phosphatase (High); Aspartate Aminotransferase (High); Bilirubin (High); Calcium Corrected (Low/High); Creatinine (High); Glucose (Low/High); Magnesium (Low/High); Potassium (Low/High); Sodium (Low/High)\] will be graded using NCI-CTCAE, Version 4.03. Clinically notable shift is defined as a worsening from baseline by at least 2 grades, or to grade 3 or above. Number of participants with at least one clinically notable shift during study will be reported.

Clinically notable shift from baseline in coagulation parameters parameter values \[activated partial thromboplastin time (seconds), international normalized ratio (INR) or prothrombin time (seconds)\] will be graded using NCI-CTCAE, Version 4.03. Number of participants with abnormal levels or notable shift during study will be reported.

Quantitative assessment of appearance, color, specific gravity, blood, glucose, leukocytes, ketones, pH and protein at each visit and changes from baseline (for quantitative parameters) will be calculated and tabulated. Microscopy findings (normal/abnormal and clinical significance) will be recorded. Number of participants with abnormal/ clinical significant changes during study will be reported.

Clinically notable elevated values: Systolic blood pressure (BP): ≥ 160 mmHg and an increase ≥ 20 mmHg from baseline; Diastolic BP: ≥ 100 mmHg and an increase ≥ 15 mmHg from baseline; Heart rate : ≥ 120 beats/min (bpm) with increase from baseline of ≥ 15 bpm; Weight (kg) increase from baseline of ≥ 10%; Body temperature(°C) ≥ 37.5°C). Clinically notable low values: Systolic BP: ≤ 90 mmHg with decrease from baseline of ≥ 20 mmHg; Diastolic BP: ≤ 50 mmHg with decrease from baseline of ≥ 15 mmHg; Heart rate: ≤ 50 bpm with decrease from baseline of ≥ 15 bpm; Weight: ≥ 20% decrease from baseline; Body temperature \[°C\]: ≤ 36 °C. Number of participants with TEAEs related to notable changes to the vital signs after the start of study drug will be reported.

12-lead ECGs will be 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 TEAEs related to abnormal or notable changes to ECG parameters after the start of study drug will be reported.

Adverse event of special interest (AESI) are as follows: acute renal failure, cutaneous non-squamous cell carcinoma, cutaneous squamous cell carcinoma, melanomas, palmar-plantar erythrodysaesthesia syndrome, photosensitivity, rash, severe cutaneous adverse reactions, facial paresis, tachycardia, haemorrhage, hepatic failure, liver function test abnormalities, myopathy and uveitis-type events. Number and percentage of participants with at least one event of any AESI and of each category of AESI will be reported in participants.
