LONDON, UK / ACCESSWIRE / September 18, 2023 / Hemogenyx Pharmaceuticals plc (LSE:HEMO), the biopharmaceutical group developing new therapies and treatments for blood diseases, announces that Prevail Partners, LLC ("Prevail Partners"), an investment fund, has agreed to invest in the Company through a subscription for 11,066,667 ordinary shares (the "New Ordinary Shares") at a price of US$0.075 per share (approximately £0.06) for the total sum of $830,000 (approximately £668,000). The subscription price represents a premium of approximately 240% to the Company's closing share price on 14 September 2023, when agreement was reached as to the final terms of the investment. The agreement governing the subscription (the "Subscription Agreement") contains customary warranties from the Company and Prevail Partners. Following allotment, Prevail Partners will hold approximately 0.96% of the Company's issued share capital.

The Company's wholly owned subsidiary, Hemogenyx Pharmaceuticals LLC, has also signed a Master Service and Technology Agreement ("MSTA") with Prevail InfoWorks, Inc. ("InfoWorks"), a Philadelphia, PA based Contract Research Organization (CRO) and affiliate of Prevail Partners. Under the terms of the MSTA, InfoWorks is to provide clinical services and technologies for the Company's upcoming Phase I study of its anti-FLT3 chimeric antigen receptor-redirected T cells ("CAR-T cells") in subjects with relapsed/refractory acute myeloid leukemia (AML). Services include clinical site coordination, project management, data management, clinical monitoring, and pharmacovigilance (safety management) services, and the use of InfoWorks' integrated real-time data analytics platform, The Single Interface®, for clinical support and real-time data analysis. The MSTA has an initial term of 40 months, and Hemogenyx Pharmaceuticals LLC has agreed an initial statement of works relating to the Phase I AML study.

The subscription funds will in large part defray the payment made by the Company for the first stage of the work being undertaken by InfoWorks under the MSTA.

Dr Vladislav Sandler, CEO & Co-Founder of Hemogenyx Pharmaceuticals, commented: "As we seek to bring the curative power of cell therapies to a greater number of patients suffering from otherwise incurable life-threatening diseases, we are very confident in Prevail InfoWorks' ability to coordinate our Phase I clinical trial in relapsed/refractory AML. Their operational experience and expertise will enable a smooth execution of the study, while their specialization in real-time data integration and analytics will ensure fast, reliable data access to lower our clinical risk and potentially speed up our regulatory timeline. Prevail Partners' strategic investment in the Company demonstrates their confidence in our CAR-T program and in our ability to execute the upcoming clinical study."

Mary Schaheen, President of Prevail Partners, stated: "Everyone at our fund is confident in the growth and success of Hemogenyx Pharmaceuticals as they develop CAR-T cells to target acute myeloid leukemia. Furthermore, Hemogenyx Pharmaceuticals has a seasoned management team with the expertise to accelerate the company to a significant value inflection point through the completion of its planned clinical trial."

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.

Allotment of Ordinary Shares and Applications for Admission

The New Ordinary Shares will be allotted and issued subject to receipt of the subscription monies from Prevail Partners, which is to be made within 5 business days from the date of the Subscription Agreement and MSTA (such date being 14 September 2023).
