Immunization with EVX-01-CAF09b in addition to anti-PD-1 therapy was shown to be safe and well tolerated and elicit vaccine neoantigen-specific CD4+and CD8+ T cell responses at all dose levels. In addition, objective tumor responses were observed in 67% of patients. The results encourage further assessment of the antitumor efficacy of EVX-01 in combination with anti-PD-1 therapy.
"Evaxion Biotech A/S...and Personalis....announced today that Evaxion will deploy Personalis’ ImmunoID NeXT Platform in a Phase 2b trial to evaluate the efficacy and safety of Evaxion’s personalized cancer immunotherapy EVX-01. The study will combine EVX-01, a neoepitope-targeting immunotherapy based on Evaxion’s proprietary PIONEER® AI technology, with KEYTRUDA® (pembrolizumab) for the treatment of patients with metastatic melanoma."
Competitive manufacturing time was demonstrated. EVX-01 was shown to be safe and able to elicit immune responses targeting tumor neoantigens with encouraging early indications of a clinical and meaningful antitumor efficacy, warranting further study.
