Brief Summary:
The purpose of this study is to evaluate the safety, tolerability, and antitumor activity of BGB-3245 in participants with advanced or refractory tumors harboring specific v-RAF murine sarcoma viral oncogene homolog B (B-RAF) genetic mutations.

Condition or disease Intervention/treatment Phase
Solid Tumor B-Raf Mutation-Related Tumors Drug: BGB-3245 Phase 1

Detailed Description:

This is a first-in-human, Phase 1a/1b (dose escalation and expansion) study of BGB-3245 in participants with tumors harboring B-RAF mutations that are likely to respond to a RAF dimer inhibitor. BGB-3245 is a second-generation B-RAF inhibitor that has demonstrated potent inhibitory activity against the RAF family of serine/threonine kinases preclinically. In preclinical studies, BGB-3245 showed it inhibited tumor cell lines harboring non-V600 B-RAF mutations; it was also active towards B-RAF/MAP-ERK Kinase (MEK) inhibitor-resistant tumors.

Phase 1a will consist of a dose-escalation and dose-finding component to establish the MTD and/or RP2D and to evaluate the pharmacokinetics of BGB-3245 3245 in participants with MAPK pathway aberrations. Phase 1b will consist of an expansion component to further evaluate the pharmacokinetics, safety, and tolerability of BGB-3245 at the RP2D and to assess the preliminary antitumor activity of the compound in participants with select tumor types and B-RAF mutational status.
