NetworkNewsBreaks – Cyclacel Pharmaceuticals, Inc. (NASDAQ: CYCC) Shares Tumble on Disappointing Phase 3 Clinical Trial of Leukemia Candidate

Shares of Cyclacel Pharmaceuticals (NASDAQ: CYCC) are down more than 15% after the company reported that its lead candidate failed to meet its primary endpoint in a phase 3 study of elderly patients with acute myeloid leukemia (AML). The trial did not meet its primary endpoint of demonstrating statistically significant improvement in overall survival (OS) for the experimental arm versus an active control. The secondary endpoint, an improved rate of complete remission (CR), was observed in patients who had discontinued therapy at the time of analysis. Full results from the SEAMLESS study will be submitted for presentation at an upcoming medical conference. “We are disappointed not to have reached the primary endpoint of SEAMLESS. Nevertheless, the improvement in CR rate and similar safety profile are encouraging. We plan to discuss the data with European and US regulatory authorities once subgroup analyses are completed over the next few months and will report our further plans as they develop. We are grateful to the clinical investigators, and especially the patients and their families, for their contributions to this large study,” president and CEO Spiro Rombotis stated in the news release.
