EVAX Stock Heads For Best Week Since January 2025 As Cancer Vaccine Shows 89% Target Precision

• 89% of the vaccine’s targets activated specific T-cell responses, which typically help the body attack cancer cells
• All six patients in the one-year extension study showed no signs of cancer progression.
• The data will be presented in a poster presentation at ESMO Congress on October 24.

Shares of Evaxion (EVAX) jumped more than 8% in pre-market trading on Friday, after the biotech firm reported promising three-year results from a Phase 2 trial of its experimental personalized vaccine to treat advanced melanoma.

EVX-01 triggered an immune response in every patient in the trial, with 89% of the vaccine’s targets activating specific T-cell responses. T-cells help the body attack cancer cells.

At current levels, EVAX stock is up more than 41% this week, putting it on track for its biggest weekly gain in more than 21 months.

What The Phase 2 Trial Showed

The company said its Phase 2 trial for the drug enrolled 16 patients with advanced melanoma. During the first two years, patients received EVX-01 along with Merck’s (MRK) blockbuster cancer drug Keytruda. Initial results showed that 75% of patients saw their tumors shrink or disappear.

Six patients continued into a one-year extension of the trial, receiving EVX-01 alone. All six maintained their earlier responses to treatment, with no signs of cancer progression during the third year.

“What makes these three-year findings particularly compelling is not only the durability of clinical responses, but also the sustained strength and breadth of vaccine-induced T-cell immunity,” said trial investigator Muhammad Adnan Khattak.

The data will be presented in a poster presentation at the European Society for Medical Oncology (ESMO) Congress on October 24.

Evaxion’s Pipeline In Focus

Evaxion is also developing EVX-04, an experimental vaccine for acute myeloid leukemia, a type of blood cancer, and EVX-05, a vaccine candidate targeting glioblastoma, an aggressive form of brain cancer. Beyond cancer, Evaxion’s pipeline includes vaccines targeting gonorrhea and cytomegalovirus.

Evaxion had $14 million in cash as of June 30, down from $18.4 million at the end of March. The company expects its cash reserves to fund operations well into the second half of 2027.
