HCW9206 reagent has also been filed with the US Food and Drug Administration.

The Company is now seeking commercial partnerships for HCW9206 reagent sale and/or integration into CAR-T based manufacturing processes.

HCW Biologics (Nasdaq: HCWB), a clinical-stage biopharmaceutical company focused on cellular immunotherapy for hematological malignancies, chronic infections and autoimmune diseases, today announced the publication of new preclinical data in the Journal of Immunological Methods demonstrating the potential of HCW9206, the Company’s proprietary ex vivo T cell reagent, to improve the long-term survival of adoptive transfer cells and facilitate durable suppression of malignancies, chronic infections and autoimmune diseases.

“We are excited to share these preclinical data demonstrating the potential of HCW9206 to enhance the persistence and anti-tumor activity of CAR-T cells in relevant disease models,” said Peter Rhode, Chief Scientific Officer and Vice President Clinical Operations at HCW Biologics. “These findings provide further support for the development of HCW9206 as a valuable addition to CAR-T manufacturing processes.”

In a preclinical model of triple-negative breast cancer, CAR-T cells displayed poor persistence and limited anti-tumor activity. However, the introduction of HCW9206 led to a significant improvement in CAR-T cell persistence, resulting in complete tumor regression and long-term survival. Moreover, the combination of CAR-T cells with HCW9206 effectively suppressed tumor growth and led to the survival of all treated animals, while untreated animals succumbed to cancer progression.

Furthermore, in a preclinical model of HIV infection, CAR-T cells treated with HCW9206 exhibited superior persistence and viral suppression compared to untreated CAR-T cells. This finding suggests that HCW9206 could be instrumental in enhancing the efficacy of adoptive T cell transfer for the treatment of chronic infections.

Finally, in a preclinical model of rheumatoid arthritis, CAR-T cells treated with HCW9206 displayed reduced differentiation into memory stem cells and a lower expression of pro-inflammatory cytokines, indicating a potential reduction in the incidence and severity of autoimmune reactions.

The ex vivo reagent has also been filed with the US Food and Drug Administration. The Company is now seeking commercial partnerships for HCW9206 reagent sale and/or integration into CAR-T based manufacturing processes.
