Second Patient Treated with HG-CT-1 CAR-T Therapy Successfully Passes Initial Safety Evaluation
LONDON, UNITED KINGDOM / ACCESS Newswire / June 3, 2025 / Hemogenyx Pharmaceuticals plc is pleased to announce that the second patient has been successfully treated in the ongoing Phase I clinical trial of HG-CT-1, the Company's proprietary Chimeric Antigen Receptor T-cell (CAR-T) therapy for relapsed/refractory acute myeloid leukemia (R/R AML) in adults.
The treatment was well tolerated and met the trial's predefined initial safety criteria. Encouragingly, early indications of clinical efficacy are evident. The patient will continue to be monitored according to the FDA-approved trial protocol to assess whether the study's secondary endpoints are achieved.
Manufacturing of HG-CT-1 for the treatment of a third patient is currently underway.
The Phase I trial is a dose-escalation study designed to evaluate the safety and tolerability of HG-CT-1. In addition to safety, the trial includes several key secondary endpoints:
Assessing the efficacy of HG-CT-1 based on AML-specific response criteria
Evaluating overall survival
Measuring progression-free survival
Determining duration of response in patients demonstrating clinical benefit
Data related to these secondary endpoints, including efficacy, durability, and overall clinical outcomes, will be collected over time through continued follow-up of the treated patient. These secondary endpoints are critical for assessing the potential clinical impact of HG-CT-1 in a patient population with limited remaining treatment options.
Further updates will be provided as the trial progresses.
Dr Vladislav Sandler, CEO & Co-Founder of Hemogenyx Pharmaceuticals, commented:
"The successful treatment of the second patient represents a meaningful step forward for both Hemogenyx and for patients battling relapsed or refractory AML. We are encouraged by the favorable safety profile observed to date and by the early signs of efficacy. These results further validate the promise of HG-CT-1 as a novel treatment for one of the most aggressive and intractable forms of leukemia. We remain focused on advancing the clinical development of this therapy to address a critical unmet need, while also building long-term value for our shareholders."
