Cullinan Oncology to Present Updated Data Highlighting the Therapeutic Potential of CLN-081 in Patients with EGFR Exon 20 Insertion Mutation Positive Non-Small Cell Lung Cancer at the 2022 ASCO Annual Meeting

Data includes updated findings from Phase 1/2a study, including expanded patient cohort treated at a dose of 100 mg twice daily

CAMBRIDGE, Mass., April 27, 2022 (GLOBE NEWSWIRE) — Cullinan Oncology, Inc. (Nasdaq: CGEM) (Cullinan), a biopharmaceutical company focused on developing a diversified pipeline of targeted therapies for patients with cancer, today announced the presentation of updated clinical research highlighting the therapeutic potential of its lead asset, CLN-081, in patients with epidermal growth factor receptor (EGFR) exon 20 insertion mutation positive non-small cell lung cancer (NSCLC) at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting taking place in Chicago from June 3-7, 2022. CLN-081 is being evaluated in an ongoing Phase 1/2a clinical trial in patients with NSCLC whose tumors harbor EGFR exon 20 insertion mutations that have progressed on or after prior therapy.

“Patients with EGFR exon 20 insertion mutations have limited options for treatments that are safe and well-tolerated,” said Jeffrey Jones, MD, MPH, MBA, Chief Medical Officer, Cullinan Oncology. “With a differentiated clinical profile including a high response rate with favorable safety and tolerability, we believe CLN-081 has the potential to be a best-in-class treatment option for patients with persisting unmet need. We are excited to share our updated research on CLN-081 in an oral presentation at ASCO 2022.”

The Food and Drug Administration (FDA) previously granted CLN-081 Breakthrough Therapy Designation.
