Clinical Trial Summary

This study is to evaluate the efficacy and safety of JAB-30355 in adult participants with advanced solid tumors harboring TP53 Y220C mutation.

Description:

This study consists of two parts: Dose Escalation Phase (Phase 1) and Dose Expansion Phase (Phase 2a). The primary objective of dose escalation is to evaluate the safety and tolerability, and to determine the MTD of JAB-30355 monotherapy administered in participants with advanced solid tumors harboring TP53 Y220C mutation. Dose expansion will further explore JAB-30355's clinical benefit and tolerability in selected dose levels.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Dose limiting toxicity (DLT)	Number and proportion of participants who experience at least one dose limiting toxicity (DLT)	Approximately one year
Primary	Number of participants with adverse events	All patients participating in this study will be assessed for incidence and severity of adverse events (AEs) and serious AEs, including changes in laboratory values, vital signs, electrocardiograms et al.	Approximately three years
Secondary	Peak Plasma Concentration (Cmax)	Observed maximum plasma concentration after administration. Plasma concentrations of JAB-30355 from subjects will be used to calculate PK parameters.	Approximately three years
Secondary	Time to reach the observed maximum (peak) concentration (Tmax)	Time to reach the observed maximum (peak) concentration. Plasma concentrations of JAB-30355 from subjects will be used to calculate PK parameters.	Approximately three years
Secondary	Terminal half-life (t1/2)	Terminal half-life of JAB-30355 in human. Plasma concentrations of JAB-30355 from subjects will be used to calculate PK parameters.	Approximately three years
Secondary	Objective response rate (ORR)	ORR is defined as the percentage of participants with partial response (PR) or complete response (CR) based on Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.	Approximately three years
Secondary	Duration of response (DOR)	DOR is defined as the time from the date of the first documented response (CR or PR) to the earliest date of disease progression or death, whichever occurs first, as determined by investigator assessment per RECIST v1.1.	Approximately three years
