Frequently asked questions about Z-1018

What is Z-1018 used for?

Z-1018 is an investigational herpes zoster vaccine being developed for the prevention of shingles, also known as herpes zoster. It is being studied in healthy adults aged 50 years and older. The vaccine is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

Who makes Z-1018?

Z-1018 is being developed by Dynavax Technologies Corporation, a biopharmaceutical company traded on NASDAQ under the ticker symbol DVAX. The company is conducting clinical trials to evaluate the safety and immunogenicity of this investigational herpes zoster vaccine.

What phase is Z-1018 in?

Z-1018 is in Phase 1 clinical development. It is an investigational vaccine and has not been approved by the FDA or any other regulatory agency. Two Phase 1 trials have been conducted, one completed and one active but not recruiting, to assess its safety and immune response.

What clinical trials is Z-1018 in?

Z-1018 has been studied in two Phase 1 clinical trials. NCT05245838, a completed trial with 150 participants, evaluated safety and immunogenicity compared to Shingrix in healthy adults. NCT06569823, an active trial with 764 participants, is comparing Z-1018 to Shingrix in healthy adults aged 50 and over.

Is Z-1018 the same as Shingrix?

No, Z-1018 is not the same as Shingrix. Z-1018 is an investigational herpes zoster vaccine being developed by Dynavax Technologies, while Shingrix is a licensed vaccine manufactured by GSK. Clinical trials are comparing Z-1018 directly against Shingrix to evaluate its safety and immunogenicity.

What does Z-1018 target?

Z-1018 is a vaccine designed to prevent shingles, which is caused by the varicella-zoster virus. As a vaccine, it works by stimulating the immune system to produce a protective response against the virus. The specific antigen or molecular target has not been disclosed in the available information.
