Elicio Therapeutics revealed preliminary data from their AMPLIFY-7P Phase 1a study of ELI-002 7P at the ASCO 2024 Annual Meeting. The cancer vaccine candidate, targeting mKRAS-driven solid tumors, showed promising results. ELI-002 7P was well tolerated and induced a significant (~100x) mKRAS-specific T cell response in all enrolled patients.
Key findings included CD8+ and CD4+ responses in 66.7% of patients at the 4.9 mg dose, and tumor biomarker reductions in 71% of evaluable patients. Antigen-spreading, targeting non-immunizing tumor neoantigens, was observed in all patients at the 4.9 mg dose. The study supports further development, with the recommended Phase 2 dose being 10.0 mg AMP-CpG-7909 with 4.9 mg AMP-Peptides 7P.
