## About

Established in 2021 and based in Oxford, UK, Infinitopes Limited operates as a manufacturer of cancer-related vaccines. In January 2026, Infinitopes Limited raised USD 15.4 million in seed funding co-led by Octopus Investments and AmplifyBio, LLC, with participation from Cancer Research Horizons, Manta Ray Ventures and Macmillan Cancer Support. The round was part of a larger USD 35.1 million seed funding.

The product has been created by the business utilizing the Precision ImmunomicsTM pipeline, which identifies highly expressed and immunogenic tumor antigens by combining state-of-the-art laboratory techniques, computational analysis, and machine learning. Comparing this platform to known antigens in preclinical models, it has shown efficacy, suggesting revolutionary breakthroughs in the development of cancer vaccines.
