Taiho Oncology and Cullinan Therapeutics Announce Pivotal REZILIENT1 Phase 1/2 Data Published in the Journal of Clinical Oncology |
| [01-June-2025] |
PRINCETON, N.J. and CAMBRIDGE, Mass., June 1, 2025 /PRNewswire/ -- Taiho Oncology, Inc., and Cullinan Therapeutics, Inc., announced today the publication of positive results from the REZILIENT1 trial in the peer-reviewed Journal of Clinical Oncology (JCO). REZILIENT1 is a Phase 1/2, global, multicenter study of zipalertinib (development code: CLN-081/TAS6417) in patients with non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) exon 20 insertion mutations (ex20ins) who have received prior therapy. Results from the REZILIENT1 trial will be presented in a simultaneous oral presentation at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting (Abstract #8503).
The full publication, titled Zipalertinib in Patients With Epidermal Growth Factor Receptor Exon 20 Insertion-Positive Non-Small Cell Lung Cancer Previously Treated With Platinum-Based Chemotherapy With or Without Amivantamab, can be found here. Highlights of the REZILIENT1 Phase 1/2 trial in the authors' conclusions include:
"Despite recent treatment advances for patients with EGFR ex20ins-mutant NSCLC, there is a lack of oral targeted therapies for patients whose tumors harbor these mutations," said principal investigator Zofia Piotrowska, MD, Assistant Professor, Medicine, Harvard Medical School and a clinical researcher and lung cancer medical oncologist at the Massachusetts General Hospital Cancer Center. "Findings from the Phase 1/2 REZILIENT1 trial support our understanding of zipalertinib as a potential targeted therapy option for patients living with previously treated recurrent or metastatic NSCLC harboring EGFR ex20ins mutations." Taiho Oncology is actively recruiting patients in the Phase 3 REZILIENT3 trial (NCT05973773). About REZILIENT1 About Zipalertinib Zipalertinib is being developed by Taiho Oncology, Inc., its parent company, Taiho Pharmaceutical Co., Ltd., and in collaboration with Cullinan Therapeutics, Inc. in the U.S. About EGFR Exon 20 Insertion Mutations About Taiho Oncology, Inc.
