Core Viewpoint - Evaxion A/S has initiated a one-year extension of its ongoing phase 2 trial for its personalized cancer vaccine EVX-01, aimed at treating advanced melanoma, leveraging its AI-Immunology™ platform to explore the vaccine's long-term clinical and immune benefits [1][2][4]. Group 1: Trial Details - The first patient has been dosed in the one-year extension of the trial, which will involve two additional doses of EVX-01 as monotherapy [3]. - The initial two years of the trial involved EVX-01 in combination with standard anti-PD-1 therapy, and the extension phase allows for evaluation of EVX-01 as a standalone treatment [4][5]. - The trial extension incurs minimal costs since trial sites are already operational and the vaccine has been produced [2][10]. Group 2: Clinical Data and Results - Interim one-year data presented at the ESMO Congress in September 2024 showed a 69% Overall Response Rate, with tumor target lesions reduced in 15 out of 16 patients [8]. - At the AACR Annual Meeting in April 2025, it was reported that 80% of EVX-01's vaccine targets triggered a targeted immune response, indicating favorable outcomes compared to other treatment approaches [9]. - The completed phase 1/2a clinical trial demonstrated that 67% of metastatic melanoma patients had objective clinical responses, highlighting the predictive power of the AI-Immunology™ platform [12]. Group 3: Product and Technology Overview - EVX-01 is a personalized peptide-based cancer vaccine designed to engage the patient's immune system against tumors, tailored to each individual's unique tumor profile [6][11]. - The AI-Immunology™ platform is central to Evaxion's approach, enabling the development of novel immunotherapies for various diseases, including cancer [13].
