Hemogenyx Pharmaceuticals PLC Announces Full FDA Review for HEMO-CAR-T IND

LONDON, UK / ACCESSWIRE / July 10, 2023 / Hemogenyx Pharmaceuticals plc (LSE:HEMO), the biopharmaceutical group developing new therapies and treatments for blood diseases, announces that the Company has received a full review letter from the U.S. Food and Drug Administration (“FDA”) regarding the Investigational New Drug (“IND”) application forthe Company’s product candidate Chimeric Antigen Receptor (“CAR”) T-cells (“HEMO-CAR-T”) for the treatment of acute myeloid leukaemia (“AML”) to the effect that HEMO-CAR-T be put on clinical hold (“CH”). The letter contains a detailed description of the rationale for the decision to put HEMO-CAR-T IND on CH. The reason for the CH relates to a splicing that occurs during the manufacturing process of the lentivirus that is used to produce CAR-T cells. The Company has identified the source of the splicing deficiency and has already developed a method to eliminate it. The lentivirus is being remanufactured. The CH letter also contains several suggestions on how to improve the safety of HEMO-CAR-T. These suggestions do not and would not contribute to the CH and can be dealt with readily.

Dr Vladislav Sandler, CEO & Co-Founder of Hemogenyx Pharmaceuticals, commented: “We are confident that we will be able to address the FDA’s questions and concerns regarding the IND. AML has poor survival rates and we are eager to resolve this hold and continue down the treatment development pathway toward saving lives.”

About AML and CAR-T Therapy

AML, the most common type of acute leukemia in adults, has poor survival rates (a five-year survival rate of less than 30% in adults) and is currently treated using chemotherapy, rather than the potentially more benign and effective form of therapy being developed by Hemogenyx Pharmaceuticals. The successful development of a new therapy for AML would have a major impact on treatment and survival rates for the disease.

CAR-T therapy is a treatment in which a patient’s own T-cells, a type of immune cell, are modified to recognize and kill the patient’s cancer cells. The procedure involves: isolating T-cells from the patient; modifying the isolated T-cells in a laboratory using a CAR gene construct (which allows the cells to recognize the patient’s cancer); amplifying (growing to large numbers) the newly modified cells; and re-introducing the cells back into the patient.
