About HB-200
Eseba-vec (also known as HB-200) is an investigational immunotherapeutic agent being evaluated for HPV16 positive cancers. HB-200 alternates the administration of both HB-201 (LCMV) and HB-202 (PICV), collectively referred to as “HB-200,” attenuated viral vectors, which on their own are replicating-based therapeutics expressing a non-oncogenic, but highly immunogenic, E7E6 fusion protein from HPV16. Positive preliminary data from a Phase 2 trial (NCT04180215) of HB-200 in combination with pembrolizumab in patients with recurrent/metastatic HPV16 positive head and neck cancers in the first line setting was presented in November 2024 at the Society for Immunotherapy of Cancer (SITC) Conference. Trial close out activities were completed before the end of 2025. HB-200 received Fast Track Designation from the U.S. Food and Drug Administration and PRIME designation from the European Medicines Agency. HB-200 was developed using HOOKIPA’s proprietary arenavirus platform.
About HB-700
HB-700 is an investigational arenaviral immunotherapy designed to treat KRAS-mutated lung, colorectal, pancreatic and other cancers. HB-700 is a replicating 2-vector therapy that targets the most prevalent KRAS mutations (G12D, G12V, G12R, G12C and G13D) and has the potential to benefit more patients than single mutation inhibitors. HB-700 received Investigational New Drug application clearance from the Food and Drug Administration in April 2024 and is Phase 1 ready, with clinical trial material manufacturing completed.
