About the study

This is a Phase 1, open-label dose-escalation study to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) and assess the DLT of JAB-3312. It is anticipated that approximately 24 subjects will be enrolled in the dose-escalation phase of the study. JAB-3312 will be administered orally once daily (QD) in 21-day treatment cycles.
