Evaluating JAB-21822 for Advanced Solid Tumors with KRAS G12C Mutation

A Phase 1/2, Multi-Center, Open-Label Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Evidence of Antitumor Activity of JAB-21822 Monotherapy and Combination Therapy in Adult Patients With Advanced Solid Tumors Harboring KRAS G12C Mutation

Phase1; Phase2 Interventional Jacobio Pharmaceuticals Co., Ltd. · NCT05002270

This study is testing a new drug called JAB-21822 to see if it can help adults with advanced solid tumors that have a specific mutation, including lung and colorectal cancers.

What this trial studies

This study evaluates the safety and tolerability of JAB-21822, a KRAS G12C inhibitor, in adult patients with advanced solid tumors, including non-small cell lung cancer (NSCLC) and colorectal cancer (CRC). The trial consists of a dose escalation phase to determine the maximum tolerated dose (MTD) and a dose expansion phase to assess the preliminary antitumor activity of JAB-21822 alone and in combination with cetuximab. Participants must have previously received standard therapy and have measurable lesions as defined by RECIST criteria.

Who should consider this trial

Good fit: Ideal candidates are adults with advanced solid tumors confirmed to have the KRAS G12C mutation who have received at least one prior treatment.

Not a fit: Patients with brain or spinal metastases, active infections, or severe uncontrolled medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new targeted therapy option for patients with advanced solid tumors harboring the KRAS G12C mutation.

How similar studies have performed: Other studies targeting KRAS mutations have shown promise, indicating potential for success with this approach.
