By treating patients before their tumors are surgically removed, Infinitopes can analyze the resected tissue. This provides direct evidence of CD8 T cell infiltration in response to the vaccine—a powerful, mechanistic proof-point that is impossible for competitors testing in later-stage patients.
Infinitopes' platform uses immunopeptidomics to directly measure peptides on a tumor's surface. This contrasts with competitors like Moderna and BioNTech, who rely on computational predictions from DNA sequencing. This "measure, don't predict" approach aims for more reliable identification of potent immune targets.
Unconventionally, Infinitopes' first-in-human trial targets neoadjuvant patients (newly diagnosed, pre-surgery). This provides cleaner efficacy signals compared to trials in heavily pre-treated patients and enables unique analysis of resected tumors to prove the vaccine's mechanism, a key differentiator from competitors.
For its seed extension, Infinitopes deliberately targeted Amplify Bio, a US investor, not just for capital but for specific experience in cancer vaccines and AI. This move provides deep domain expertise and strategically positions the company for future access to larger US capital markets for subsequent financing rounds.
