- New data from the phase 2 trial with EVX-01 to be presented in both an oral and poster session
COPENHAGEN, Denmark, November 3, 2026 - Evaxion A/S (NASDAQ: EVAX) (“Evaxion”), a clinical-stage TechBio company developing novel immunotherapies with its pioneering AI-Immunology™ platform, will present new biomarker data from its phase 2 trial with personalized cancer vaccine EVX-01 at the Society for Immunotherapy of Cancer (SITC) 2026 Annual Meeting, taking place in Phoenix, Arizona, November 4-8, 2026.
The new data includes analysis of broad systemic immunomodulatory effects of EVX-01 plus pembrolizumab beyond vaccine-specific T-cell responses. It will be presented in both an oral and poster session at the SITC meeting.
To further understand the immunological mechanisms underlying EVX-01 activity, we performed longitudinal immune profiling of treated patients. The analyses included characterization of vaccine-specific T-cell responses together with profiling of systemic, treatment-associated immune responses. These data provide insights into the magnitude, quality, durability, and systemic impact of EVX-01-induced immunity in advanced melanoma.

About the phase 2 trial
The phase 2 trial investigated EVX-01 in patients with advanced melanoma (skin cancer). Each patient enrolled in the trial received a unique vaccine designed with Evaxion’s AI-Immunology™ prediction platform and manufactured based on their individual biology.
At two-year follow-up, the trial demonstrated an Objective Response Rate (ORR) of 75% as 12 out of 16 patients had objective clinical responses, with four patients obtaining a complete response. Clinical and T-cell responses were sustained at three-year follow-up. 89% of the EVX-01 neoantigen targets triggered a tumor-specific immune response in the patients.
In the first two-years, patients received EVX-01 in combination with MSD’s (Merck & Co., Inc., Rahway, NJ, USA) anti-PD-1 therapy, KEYTRUDA® (pembrolizumab). In the third year, a subset of patients received EVX-01 as stand-alone therapy. KEYTRUDA® is a registered trademark of Merck Sharp & Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA.
About EVX-01
EVX-01 is a personalized peptide-based cancer vaccine intended for first-line treatment of multiple advanced solid cancer tumors. It is currently being evaluated as a treatment of advanced melanoma and is Evaxion’s lead clinical asset.
Designed with our AI-Immunology™ platform, EVX-01 is tailored to target the unique tumor profile and immune characteristics of each patient. It engages the patient's immune system by mounting a targeted response against tumor-specific neoantigens.
