CAMBRIDGE, Mass., April 23, 2025 (GLOBE NEWSWIRE) -- Cullinan Therapeutics, Inc. (Nasdaq: CGEM), a biopharmaceutical company focused on developing modality-agnostic targeted therapies, today announced that results from the REZILIENT1 study of zipalertinib in non-small cell lung cancer (NSCLC) patients with EGFR exon 20 insertion mutations (ex20ins) who have received prior therapy will be presented in an oral abstract session at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting taking place in Chicago from May 30–June 3, 2025. The data will include results from the Phase 2b portion of the study, which explored zipalertinib monotherapy in patients with advanced or metastatic EGFR ex20ins NSCLC who progressed after prior treatment with platinum-based chemotherapy with or without amivantamab and other ex20ins-targeted therapies.
“Despite an evolving treatment landscape, patients with non-small cell lung cancer with EGFR exon 20 insertion mutations continue to have limited treatment options and poor disease outcomes,” said Jeffrey Jones, MD, MBA, Chief Medical Officer, Cullinan Therapeutics. “The results from REZILIENT1 show zipalertinib demonstrated clinically meaningful efficacy and a manageable safety profile in patients who have received prior platinum-based chemotherapy, including those who were treated with amivantamab, and zipalertinib has the potential to address significant unmet need in these patient settings. We look forward to sharing these important results with the lung cancer community through our oral presentation at the 2025 ASCO Annual Meeting.”
The details of the presentation include:

Zipalertinib is designed as a next generation, irreversible EGFR inhibitor for the treatment of a genetically defined subset of patients with non-small cell lung cancer. Zipalertinib has received Breakthrough Therapy Designation from the FDA.
Zipalertinib is being developed by Taiho Oncology, Inc., its parent company, Taiho Pharmaceutical Co., Ltd., and Cullinan Therapeutics, Inc.
