Dynavax Initiates Phase 1/2 Study of Novel Shingles Vaccine Program
EMERYVILLE, Calif., June 27, 2024 /PRNewswire/ -- Dynavax Technologies Corporation (Nasdaq: DVAX), a commercial-stage biopharmaceutical company developing and commercializing innovative vaccines, today announced that the first participant has been dosed in a Phase 1/2 clinical trial evaluating the safety, tolerability, and immunogenicity of Z-1018, the company's investigational vaccine candidate being developed for the prevention of shingles (herpes zoster), a debilitating disease caused by the varicella-zoster virus.
"We believe there is an opportunity to develop an improved shingles vaccine with a significantly better tolerability profile compared to the market-leading shingles vaccine. One of the unique advantages of our vaccine candidate is CpG 1018 adjuvant's established safety and tolerability profile, combined with its ability to induce strong CD4+ T-cell responses, which are thought to be critical in preventing the reactivation of the herpes zoster virus," said Rob Janssen, M.D., Chief Medical Officer of Dynavax.
The Phase 1/2 randomized, active-controlled, dose escalation, multicenter trial is expected to enroll approximately 440 healthy adults aged 50 to 69 years at trial sites in Australia, and will evaluate the safety, tolerability, and immunogenicity of Z-1018 compared to Shingrix®. Key objectives of the trial include selecting the optimal glycoprotein E (gE) protein dose level and dosing schedule for further clinical development. The Phase 1/2 trial will be used to support validation of a Patient Reported Outcome measurement tool to differentiate Z-1018 on tolerability and to support potential label claims. Dynavax anticipates reporting top line immunogenicity and safety data in the second half of 2025, including a comparison of CD4+ T-cells one month after the second of two vaccine doses.
Shingles is an extremely painful consequence of the reactivation of a latent varicella-zoster virus infection, the same virus that causes childhood chickenpox, with attacks leading to potential complications including chronic pain. While there are currently approved vaccines for shingles, there is an unmet medical need for a shingles vaccine with both high efficacy and improved tolerability.
