Overview
Brief Summary
This study is to evaluate the safety and tolerability of JAB-21822 monotherapy and combination therapy in adult participants with advanced solid tumors harboring KRAS G12C mutation.
Detailed Description
The primary objective of this study is to evaluate the safety and tolerability of JAB-21822 monotherapy to determine the MTD and PR2D during Dose Escalation phase; then to evaluate preliminary antitumor activity when JAB-21822 administered alone and combination with cetuximab during Dose Expansion phase in adult participants with advanced solid tumors harboring KRAS G12C mutation.

Arms & Interventions
Experimental: Arm B, JAB-21822 combination with Cetuximab, Phase 2, Dose Expansion
JAB-21822 will be administered together with Cetuximab in mCRC patients to evaluate the preliminary antitumor activity.
Intervention: Cetuximab (EGFR inhibitor) (Drug)
Arm A1, JAB-21822 monotherapy, Phare 2, Dose Expansion
JAB-21822 will be administered alone at RP2D in selected cancer type patients to evaluate the preliminary antitumor activity.
Intervention: JAB-21822 (KRAS G12C inhibitor) (Drug)
Experimental: Arm B, JAB-21822 combination with Cetuximab, Phase 2, Dose Expansion
JAB-21822 will be administered together with Cetuximab in mCRC patients to evaluate the preliminary antitumor activity.
Intervention: JAB-21822 (KRAS G12C inhibitor) (Drug)
Arm A0, JAB-21822 monotherapy, Phase 1, Dose Escalation
Dose escalation of JAB-21822 will be administered alone to determine the MTD and RP2D
Intervention: JAB-21822 (KRAS G12C inhibitor) (Drug)
Outcomes
Primary Outcomes
Dose Escalation phase: Number of participants with dose limiting toxicities (DLTs)
Time Frame: At the end of Cycle 1 (each cycle is 21 days)
Dose Escalation and Dose Expansion phase: Number of participants with adverse events
Time Frame: Up to 4 years
Patients will be assessed for incidence and severity of adverse events (AEs) according to NCI-CTCAE criteria
Dose Expansion phase: Overall response rate (ORR)
Time Frame: Up to 4 years - from baseline to RECIST confirmed Progressive Disease
ORR is defined as the percentage of participants with complete response (CR) or partial response (PR) per RECIST v 1.1
Dose Expansion phase: Duration of response ( DOR )
Time Frame: Up to 4 years
DOR is defined as the time from the participant's initial objective response (CR or PR) to disease progression per CTCAE v1.1 or death due to any cause, whichever occurs first.
Secondary Outcomes
- Dose Escalation and Dose Expansion phase: Peak Plasma Concentration (Cmax)(Up to 4 years)
- Dose Escalation and Dose Expansion phase: Area under the plasma concentration versus time curve (AUC)(Up to 4 years)
- Dose Escalation phase: Overall response rate (ORR)(Up to 4 years - from baseline to RECIST confirmed Progressive Disease)
- Dose Escalation phase: Duration of response ( DOR )(Up to 4 years)
- Dose Escalation and Dose Expansion phase: Disease Control Rate ( DCR )(Up to 4 years)
- Dose Escalation and Dose Expansion phase: Progression-free survival (PFS)(Up to 4 years)
