About HB-300
HB-300 is an alternating, 2-vector replicating arenaviral immunotherapy for metastatic castration-resistant prostate cancer (mCRPC). HB-300 uses the lymphocytic choriomeningitis virus (LCMV) and pichinde virus (PICV) as arenaviral backbones, with each expressing two well-defined antigens of prostate cancer, prostatic acid phosphatase (PAP) and prostate-specific antigen (PSA). HOOKIPA’s approach is designed to focus the immune response against the target antigens and has demonstrated the ability to induce potent antigen-specific T cells responses and anti-tumor activity in preclinical and clinical settings.
