A Phase II Study Evaluating JAB-21822 Monotherapy in Adult Patients With Pancreatic Cancer and Other Solid Tumors Harboring the KRAS p.G12C Mutation.

This study is a single-arm, multicenter, open-label, basket-design, pivotal phase II trial targeting adult patients with locally advanced or metastatic solid tumors harboring the KRAS p.G12C mutation. The included populations are:

• Patients with advanced pancreatic cancer who have progressed or are intolerant to prior gemcitabine-based chemotherapy regimens or FOLFIRINOX/mFOLFIRINOX/NALIRIFOX treatments.
• Patients with other advanced solid tumors (excluding NSCLC and CRC) who have progressed after prior systemic therapies or are intolerant and lack satisfactory alternative treatment options.

The study aims to evaluate the efficacy and safety of Glecirasib in these patient populations.

Inclusion criteria

• Patients with the KRAS p.G12C mutation confirmed through testing using prospectively validated companion diagnostic reagents or clinical trial assay (CTA) methods.
• Histologically or cytologically confirmed locally advanced unresectable or metastatic solid tumors (excluding NSCLC and CRC).
• Patients with pancreatic cancer must have progressed or been intolerant to prior gemcitabine-based chemotherapy regimens or FOLFIRINOX/mFOLFIRINOX/NALIRIFOX treatment. Patients with other types of solid tumors must have progressed or been intolerant to prior systemic therapies and lack satisfactory alternative treatment options.

Exclusion criteria

• Previously received a KRAS G12C inhibitor.
• History of interstitial lung disease, non-infectious pneumonia, or uncontrolled lung disease (including pulmonary fibrosis, acute lung disease, etc.) with clinical symptoms.
• Uncontrolled pleural effusion, pericardial effusion, or ascites.
• Mean QT interval corrected for heart rate using Fridericia's formula (QTcF) ≥470 ms calculated from 3 electrocardiograms.
• Use of a drug with known risk of torsades de points (TdP) within 14 days prior to the first dose.
