  • New clinical data demonstrates antitumor effect of EVX-01 in combination with anti-PD1 treatment

  • Objective Response Rate (ORR) of 67% with EVX-01 + anti-PD1 treatment in nine metastatic melanoma patients, including 22% Complete Response (CR) and 44% Partial Response (PR)

  • Clinical trial data supports the proprietary AI-Immunology platform, PIONEER, with regard to: neoepitope prediction, de novo T-cell activation and clinical response in cancer patients

  • Phase 2 trial of EVX-01 in melanoma, planned to start in December 2021

  • First patients in Phase 1/2a trial of EVX-02 showed T-cell activation, with further data to be generated with aim of initiating Phase 2 trial in Q2 2022

COPENHAGEN, Denmark, July 08, 2021 (GLOBE NEWSWIRE) -- Evaxion Biotech A/S (NASDAQ: EVAX), a clinical-stage biotech company specializing in the development of AI-driven immunotherapies to improve the lives of patients with cancer and infectious diseases, announced today results from both its Phase 1/2a trial of cancer immunotherapy EVX-01 in metastatic melanoma and interim Phase 1/2a trial of cancer immunotherapy EVX-02 in adjuvant melanoma.

Data from the trial of EVX-01, a novel patient-specific cancer neoepitope immunotherapy based on Evaxion’s PIONEER AI technology in combination with a PD-1 checkpoint inhibitor, showed a safety profile with only Grade 1 and 2 adverse events observed.

Combined therapy with EVX-01 demonstrated an objective response rate of 67% across all nine patients compared with historical data of 40% with anti-PD1 treatment alone1. The study also demonstrated a complete response rate of 22%, compared with a historical 7%1 with anti-PD1 treatment alone, and a partial response rate of 44%, versus 33% compared with anti-PD1 treatment alone1. Among the four patients on the highest two doses, there was an objective response rate of 75%. Three patients with Stable Disease for 10, 8 and 9 months on anti-PD1 treatment alone, achieved CR, CR and PR respectively following EVX-01 administration and subsequent activation of a neoepitope specific de novo T-cell response.

Lars Wegner, CEO of Evaxion, said: “We are very excited about the Phase 1/2a data for EVX-01, which shows encouraging results for our AI-developed immunotherapy in metastatic melanoma and appears to be well tolerated with only Grade 1 and 2 adverse events such as fatigue and fever all of which were resolved with treatment. The complete elimination of all tumors we see in the two patients stable for 8-10 months on checkpoint inhibitor treatment has further increased our belief in the benefit our neoepitope-based therapies can bring to patients. In addition, the tumor reduction in patients correlates with neoepitope specific T-cell activation and PIONEER predictions. The data demonstrate the potential of our PIONEER platform and its ability to identify patient specific cancer neoeptiopes. Importantly, the objective response rate demonstrates that EVX-01 may be able to improve the treatment landscape in melanoma and potentially other cancers. Furthermore, the first results from our Phase 1/2a trial with EVX-02 demonstrate its potential for treatment of melanoma. Based on the data from these two studies, we expect to initiate a Phase 2 trial with EVX-01 by the end of the year and a Phase 2 trial with EVX-02 in Q2 2022.”

Professor Inge Marie Svane, Head of the Danish Centre for Cancer Immunotherapy and Principal Investigator of the EVX-01 study, said: “These Phase 1/2a data demonstrate the feasibility of the combination of EVX-01 with anti-PD1 therapy with substantial reduction of tumor burden in some patients. It is particularly interesting to see that two patients improved their response to anti-PD1 therapy further to complete response following addition of EVX-01. This could be good news for patients and I look forward to contributing to the further development of this novel therapy.”

About the EVX-01 Phase 1/2a clinical trial in metastatic melanoma
In the Phase 1/2a trial, nine patients with metastatic melanoma were injected biweekly with EVX-01, three times intraperitoneal and three times intramuscular plus, with pembrolizumab every three weeks or nivolumab every four weeks. Patients were dosed at three different levels of EVX-01, 500 μg, 1,000 μg and 2,000 μg.

The study also revealed encouraging biomarker information supporting EVX-01’s mechanism of action. There was broad T-cell activation in all patients, with 76.2% of the administered neoepitopes inducing reactive T cells, while 84.8% of EVX-01 induced reactive T cells were de novo responses. Patient cases established a direct link between EVX-01 activated T cells and antitumor effect and duration of response. The data further demonstrated a link between neoepitopes identified by the PIONEER platform and clinical response.

The results also showed that Evaxion’s novel proprietary AI-Immunogenetic Drug Response Platform (AI-DeeP™), which provides immuno-genetic profiling of individual patients based on biological rational for drug response, can predict the response to therapy with precision and sensitivity.

We believe that the data support progressing the development of EVX-01 into a subsequent randomized Phase 2b trial, which we expect to initiate in December 2021. We also intend to present the data at a upcoming medical society meeting in first half of 2022.

Phase 1/2a results with EVX-02 in adjuvant melanoma

This is an open label, multi-center study assessing the safety, tolerability, pharmacodynamics, and potential efficacy of EVX-02 in combination with checkpoint inhibitor in patients who have had a complete resection of Stage IIIB/IIIC/IIID or Stage IV melanoma and are at high risk of recurrence. The study is taking place at five clinical centers in Australia.

Data from the first patients in the trial showed T-cell activation, even in assays which had not been prestimulated. Based on this readout, Evaxion will continue to generate more data from the trial with the aim of initiating a Phase 2 trial with EVX-02 in an adjuvant setting in the second quarter of 2022.
