Vaccitech Presents Interim Data from Phase 1b/2 Study of VTP-200 at 35th Annual International Papillomavirus Conference (IPVC) Highlighting Favourable Tolerability and Immunogenicity Profile

April 17, 2023 – Clinical Trials




OXFORD, United Kingdom, 17 April, 2023 (GLOBE NEWSWIRE) – Vaccitech plc (NASDAQ: VACC), a clinical-stage biopharmaceutical company focused on the development of novel T cell immunotherapeutics designed to harness the power of the immune system to treat and cure chronic infectious diseases, autoimmune diseases and cancer, will present topline data from the APOLLO clinical trial at the 35th Annual International Papillomavirus Conference (IPVC). The APOLLO trial (also known as HPV001) is a fully enrolled Phase 1b/2 study of VTP-200 in women with low-grade cervical lesions associated with persistent human papillomavirus (HPV) infection. The data will be presented as a poster at IPVC in Washington, D.C. on Thursday, April 20, 2023 at 2 PM EDT, by Dr. Meg Marshall, Chief Medical Officer of Vaccitech.

‘The safety and immunogenicity data presented at IPVC shows the potential of VTP-200 in treating persistent high-risk HPV (hrHPV) infections. Currently, women with persistent HPV infections have no treatment options until they develop high grade lesions,’ said Meg Marshall, CMO of Vaccitech. ‘We believe VTP-200 has the potential to address a serious unmet need and look forward to sharing the results of the final analysis, to include data on clearance of infection and cervical lesions, in 2024.’

The poster shows data for 42 women at Day 35, 7 days after the last dose of VTP-200, split by active treatment versus placebo. VTP-200 was generally well-tolerated and was administered with no product-related grade 3 unsolicited adverse events and no product-related SAEs. While the placebo group showed no antigen-specific T cell responses as measured by IFNg ELISpot, 26 of 29 women receiving varying doses of VTP-200 showed a response. The pooled active groups showed meaningful responses, with the average being greater than 1,000 spot-forming units per million peripheral blood mononuclear cells. Responses were strongest to the E1, E2 and E6 antigens. In addition, intracellular cytokine staining data from the active groups showed both CD4 and CD8 responses.
