Details and patient eligibility

About

This study is to evaluate the safety and tolerability of pan-KRAS inhibitor JAB-23E73 in adult participants with advanced solid tumors

Full description

Study JAB-23E73-1002 is a multicenter, open-label Phase 1/2a study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary anticancer activity of JAB-23E73 as a single agent in adult patients with advanced solid tumors with KRAS alteration. This study consists of a Phase 1a dose-escalation, followed by Phase 1b dose-expansion and Phase 2a indication expansion. After completing dose-escalation, the MTD or preliminary RP2D of JAB-23E73 will be determined. The RP2D will be determined according to the safety, efficacy and PK data from phase 1b. The indication expansion phase will further explore the efficacy and safety in advanced KRAS-alternated tumors which consist of 3 cohorts: Cohort C1, the CRC cohort; Cohort C2, the PDAC cohort; and Cohort C3, other solid tumor cohort.
