Clinical Trial Summary

This is a Phase 1/2a, first-in-human, open-label study of JAB-8263, this study has two parts: solid tumor dose escalation and expansion study and hematology tumor dose escalation and expansion study. These two parts will determine the maximum tolerated dose (MTD), recommended Phase 2 dose (RP2D) and assess the DLT of JAB-8263 in treatment with patients with advanced solid tumors and hematology tumors separately. 30 subjects each will be enrolled.


Clinical Trial Description

JAB-8263 is a small-molecule inhibitor of the highly conserved bromodomain pockets of the bromodomain and extraterminal (BET) proteins. The objectives of this study are: To determine the maximum-tolerated dose (MTD) and assess the dose-limiting toxicity (DLT) of JAB-8263 as a single agent to adult subjects with advanced malignant tumors. To assess the safety and tolerability of JAB-8263 To characterize the pharmacokinetic (PK) parameters and pharmacodynamics (PDc).To evaluate preliminary antitumor activity of JAB-8263 ;
