Description of intervention(s) / exposure
This is a multicenter, Phase I, open label, multiple dose, dose escalation, first in human study of the B-RAF inhibitor BGB-283.

The dose levels will be escalated throughout the study up to the MTD or the predicted efficacy level. Dose escalation will follow a standard 3+3 dose escalation design (detail is described as below).

Cohort 1: 5 mg oral capsule once daily
Cohort 2: 10 mg oral capsule once daily
Cohort 3: 20 mg oral capsule once daily
Cohort 4: 30 mg oral capsule once daily
Cohort 5: 40 mg oral capsule once daily
Cohort 6: 60 mg oral capsule once daily

The starting dose will be 5 mg/day (5 mg once daily). The 24 day initial treatment cycle (Cycle 1) of each dose will consist of a single administration of BGB-283 (Day 1), followed by a 2 day treatment free period (Days 2 and 3) and a 21 day period of repeated drug administration (Days 4 to 24).

Evaluation of a cohort of at least three (3) subjects completing one cycle of treatment at that dose level is required prior to determining the next dose level and dose regimen for the next cohort.

If a subject wishes to continue study treatment on completion of Cycle 1, the subject can continue study treatment in 21 day Cycle 2 (with no treatment free or rest period) and subsequent cycles (same as Cycle 2, all of 21 days' duration), at the discretion of the investigator.

The continuous safety evaluation will be performed by the sponsor, the coordinating investigator, and investigators. A Safety Monitoring Committee (SMC) will be established for the determination of dose levels to be administered and dose regimen during dose escalation, and will depend on the data available from the previous dose levels.

The investigator is responsible for investigational product accountability, reconciliation, and record maintenance. In accordance with all applicable regulatory requirements, the investigator or designated study center personnel must maintain investigational product accountability records throughout the course of the study. This person(s) will document the amount of investigational product received from the sponsor, the amount supplied and/or administered to and returned by subjects, if applicable. After completion of the study, all unused BGB-283 will be inventoried and packaged for return shipment by the hospital unit pharmacist. The inventoried supplies will be returned to the sponsor or destroyed on site, after receiving written sponsor approval.

Outcomes
Primary outcome [1] 293379 0
The safety of BGB 283 will be assessed throughout the study by monitoring Adverse Events (AEs) per the National Cancer Institute Common Toxicity Criteria for AEs (NCI-CTCAE), serious adverse events (SAEs), physical examination, and laboratory measurements.
Timepoint [1] 293379 0
Monitored from day 1 to end of treatment (about 1 year) in each participant.
Primary outcome [2] 293429 0
Dose-Limiting Toxicity (DLT) will be done by monitoring each participant for study drug treatment-related toxicities at each dose level
Timepoint [2] 293429 0
Monitored after first cycle (24 days).
Primary outcome [3] 293497 0
Determination of the maximum tolerated dose (MTD) will be assessed by occurrence of DLT
Timepoint [3] 293497 0
Determined after first cycle (24 days)
Secondary outcome [1] 310906 0
To characterize the pharmacokinetics (PK) of BGB 283 after single dose and multiple dose administration.
For a single dose profile: area under the plasma concentration time curve from zero to the last measureable concentration (AUClast), area under the plasma concentration time curve from zero to infinity (AUC), maximum observed plasma concentration (Cmax), time to maximum observed plasma concentration (tmax), terminal half life (t1/2), apparent clearance (CL/F), and apparent volume of distribution (Vd/F).
After steady state: AUClast,ss, Cmax,ss, and tmax,ss.
Blood plasma samples will be assayed using LC/MS method.
Timepoint [1] 310906 0
Baseline, and day 1, 2, 3, 4, 18 of Cycle 1. Day 1 of Cycle 2 onwards
Secondary outcome [2] 310907 0
The number and proportion of subjects who achieve objective tumor response (complete response [CR], partial response [PR], and CR+PR) or stable disease (SD) using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (defined as CR, PR or SD, according to local radiological assessments from the first administration of the investigational product to the end of the study treatment).
Timepoint [2] 310907 0
Baseline, and every 6 weeks after intervention commencement
Secondary outcome [3] 310908 0
Progression free survival (defined as the interval between the day of the first administration of the investigational product and the first documentation of progressive disease (PD) or death, whichever occurs earlier. Subjects, who are withdrawn from the study without documented progression, will be censored at the date of the last tumor assessment when the subject was known to be progression free. Subjects without post baseline tumor assessments, but known to be alive will be censored at the time of the first administration of the investigational product).
Disease assessments will be performed by multiple events, such as laboratory evaluation, physical examination, vital signs, electrocardiogram, and CT scan.
Timepoint [3] 310908 0
End of study (about 1 year)
Secondary outcome [4] 310909 0
Duration of response for responders (CR or PR) and duration of SD (defined only for subjects whose confirmed best response is CR or PR, as the time interval between the date of the earliest qualifying response and the date of PD or death for any cause, whichever occurs earlier. For subjects who are alive without progression following the qualifying response, duration of response will be censored on the date of last evaluable tumor assessment or last follow up for progression of disease).
Timepoint [4] 310909 0
