About

This is a Phase 1/2a, open-label, multi-center study of JAB-3068 in Patients with advanced solid tumors.This study has two phases: dose escalation phase and dose expansion phase.

Full description

Dose escalation study phase is designed to determine the maximum tolerated dose (MTD) according to a 3+3 design and recommended phase II dose (RP2D) and to characterize the safety, tolerability, and pharmacokinetics (PK) profile of JAB-3068. Other dose regimens may be explored based on the analysis of emerging PK and safety data. at this study phase, JAB-3068 dministered orally once daily (QD) or twice daily (BID) or once every other day (QOD) in 28-day treatment cycles to adult patients with advanced solid tumors,

Dose expansion study phase is designed to evaluate the antitumor activity(ORR and DOR) of JAB-3068 in patients with NSCLC, ESCC and HNSCC.

Enrollment: 126 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

126 participants in 1 patient group

JAB-3068 (SHP2 inhibitor)

Experimental group

Description:

JAB-3068 will be administered orally in the morning following a fast of approximately 6 hours before on PK collection. Patients will continue to fast for approximately 2 hours after the administration of JAB-3068. On non-PK days patients will fast approximately 2 hours before JAB-3068 and continue to fast for approximately 2 hours afterwards.
