Evaxion’s EVX-01 vaccine shows promising immune response in trial

COPENHAGEN - Evaxion Biotech A/S (NASDAQ: EVAX), a clinical-stage biotechnology company with a market capitalization of $10.42 million, has reported new data from its phase 2 trial indicating that its personalized cancer vaccine, EVX-01, triggers a tumor-specific immune response in 80% of cases. This response rate is higher than those reported for similar vaccine candidates. The company’s stock has shown recent momentum, gaining over 26% in the past week, according to InvestingPro data.

The ongoing trial, involving advanced melanoma patients, is testing EVX-01 in combination with Merck & Co.’s anti-PD-1 therapy, KEYTRUDA®. The latest immune response data will be presented at the American Association for Cancer Research (AACR) Annual Meeting in Chicago.

Previously, interim analyses showed a vaccine target hit rate of 71% and 79% at the ASCO and ESMO 2024 meetings, respectively. The new data suggests an improvement in this hit rate, which may reinforce EVX-01’s potential as a treatment for a broad range of solid tumors.

"We are excited to report yet another positive set of data for our lead vaccine candidate EVX-01," said Birgitte Rønø, CSO of Evaxion. "Its ability to trigger an immune response is unprecedented compared to what has been reported by others."

The trial’s two-year clinical data readout is expected in the second half of 2025, with the study now extended to a third year for a more comprehensive assessment of the vaccine’s full potential. The vaccine is designed using Evaxion’s AI-Immunology™ platform, tailored to each patient’s unique tumor profile and immune characteristics.

EVX-01 has shown Overall Response Rates of 69% and 67% in advanced melanoma patients in clinical trials. The platform’s predictive power is further highlighted by the significant correlations between clinical responses and AI-Immunology™ predictions.

Evaxion Biotech is focused on leveraging artificial intelligence to develop immunotherapies for cancer and infectious diseases. The company’s AI-Immunology™ platform is at the core of its product development strategy.
