Initial clinical data from global Phase 1 study of CLN-978 in Systemic Lupus Erythematosus (SLE) expected in Q4 2025; CLN-978 remains the first and only development-stage CD19 T cell engager in an autoimmune disease clinical trial in the U.S.

Zipalertinib pivotal Phase 2b study met primary endpoint; full results mid-year 2025 and NDA submission planned H2 2025, pending regulatory discussions

Cash and investments of $606.9 million as of December 31, 2024, continues to provide runway into 2028

CAMBRIDGE, Mass., Feb. 27, 2025 (GLOBE NEWSWIRE) -- Cullinan Therapeutics, Inc. (Nasdaq: CGEM; “Cullinan”), a biopharmaceutical company focused on developing modality-agnostic targeted therapies, today reported recent and anticipated business highlights and announced its financial results for the fourth quarter and full year ended December 31, 2024.

“Building on our execution throughout 2024, we are positioned to again deliver meaningful catalysts in 2025, starting with key updates for CLN-978 and zipalertinib,” said Nadim Ahmed, Chief Executive Officer of Cullinan Therapeutics. “We have established an important competitive advantage in the immunology space as CLN-978 remains the first and only development-stage CD19 T cell engager with U.S. Food and Drug Administration (FDA) IND clearance in autoimmune diseases. We are further strengthening our leadership position by rapidly expanding our site footprint and preparing to deliver initial clinical data in SLE in the fourth quarter of 2025. For zipalertinib, we recently announced that the pivotal Phase 2b portion of the REZILIENT1 study met the primary endpoint of overall response rate. This milestone marks a significant achievement for Cullinan, our partner, Taiho, and most importantly, patients with EGFR exon20 insertion mutation NSCLC who have received prior therapy. Together with Taiho, we look forward to discussing next steps with the U.S. FDA and expect to submit an NDA in the second half of 2025. We look forward to continuing to progress these programs along with the rest of our pipeline.”
