Study type
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.

Brief summary
This study will evaluate the safety, tolerability, pharmacokinetic profile and treatment effect of a new drug known as BGB-283 in patients with solid tumours.

Who is it for?
You may be eligible to join this study if you are aged 18 years or above, and have a confirmed diagnosis of advanced or metastatic solid tumour for which no effective standard therapy is available.

Study details
All participants in this study will receive treatment with a new drug known as BGB-283. Treatment will be administered by oral capsule [once daily for 24 days (Cycle 1 only) and 21 days (Cycle 2 onwards) each cycle]. Initially a low dose will be administered to participants. If this dose is tolerated, then it will be increased in the next group of patients and so on until the maximum tolerated dose is determined.

All participants will be regularly monitored for safety and tolerability of the medication for about 1 year. They will also be required to give blood samples (on days when frequent pharmacokinetic sampling is required), FDG-PET scan (screening and the first day of Cycle 2) and CT scans (screening and subsequent every 6 weeks) during the study. This will provide us with supportive data for further development of this medication.
