Conditions
Advanced Solid Tumor
Interventions
Registration Number
NCT06959615
Lead Sponsor
Jacobio Pharmaceuticals Co., Ltd.
Brief Summary

This is a multicenter, open-label, phase I/IIa to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary antitumor activity of JAB-23E73 in patients with advanced solid tumors harboring KRAS mutations or amplification. The study consists of 2 phases: Phase 1 Dose Escalation and Phase IIa Dose Expansion.

Primary Outcome Measures
NameTimeMethod
Phase 1: Number of participants with dose limiting toxicities (DLT)Up to 21 days

Incidence of dose limiting toxicities (DLTs) in the dose escalation phase. DLTs will be defined as the occurrence of any of the toxicities as described in the protocol.

Phase 2a: Objective response rate (ORR)Up to approximately 2 years

ORR is defined as the proportion of patients with a best overall response (BOR) of confirmed complete response (CR) or confirmed partial response (PR) per RECIST v1.1.

Secondary Outcome Measures
NameTimeMethod
Phase 1/2a: PK: Time to Maximum Concentration (Tmax) of JAB-23E73Up to approximately 2 years

PK: Tmax of JAB-23E73

Phase 1/2a: PK: Area Under the Concentration Versus Time Curve (AUC) of JAB-23E73Up to approximately 2 years

PK: AUC of JAB-23E73

Phase 1: ORRUp to approximately 2 years

ORR is defined as the proportion of patients with a BOR of confirmed CR or confirmed PR per RECIST v1.1.

Phase 1/2a: Safety and TolerabilityUp to approximately 2 years

Incidence and severity of treatment-emergent Adverse Events (TEAEs), treatment-related Adverse Events (TRAEs) and serious Adverse Events (SAEs), including incidence and severity of findings in laboratory values, ECG, ECOG and vital signs.

Phase 1/2a: Pharmacokinetic (PK): Maximum concentration (Cmax) of JAB-23E73Up to approximately 2 years

PK: Cmax of JAB-23E73

Phase 1/2a: Time to Response (TTR)Up to approximately 2 years

TTR is defined as the time from the date of first dose of study drug to first documentation of response as assessed by the investigator per RECIST v1.1

Phase 1/2a: Progression Free Survival (PFS)Up to approximately 2 years

PFS is defined as the time from the date of the first dose of study drug to the date of the first documentation of progressive disease assessed by the investigator per RECIST v1.1 or death, whichever occurs first.

Phase 1/2a: Disease Control Rate (DCR)Up to approximately 2 years

DCR is defined as the proportion of patients with CR, PR, or stable disease (SD) as assessed by the investigator per RECIST v1.1

Phase 1/2a: Duration of Response (DoR)Up to approximately 2 years

DOR is defined as the time from the first determination of an objective response per RECIST v1.1 until the first documentation of disease progression or death, whichever occurs first as assessed by the investigator.

Phase 2a: Overall Survival (OS)Up to approximately 2 years

OS is defined as the time from the date of first dose of study drug until the date of death from any cause.
