The Phase 1 clinical trial (DV2-ZOS-01) was designed to evaluate an investigational shingles vaccine Z-1018, utilizing different regimens of CpG 1018 adjuvant, with or without aluminum hydroxide (alum). The trial compared Z-1018 arms versus the active comparator Shingrix®. The Company reported the following topline results, assessed at Week 12, and plans to submit an abstract for presentation at an upcoming medical meeting in the first half of 2023.
- Z-1018 demonstrated high antibody and CD4 positive T-cell vaccine response rates in all arms, which were similar to the comparator;
- Robust increases in CD4 positive T-cells were observed in all Z-1018 arms, although lower than the comparator;
- Total frequency of solicited systemic adverse events and local post-injection reactions were similar across the Z-1018 arms and lower than the comparator,
- The frequency of moderate and severe local post-injection reactions was 9% for Z-1018 arms compared to 37% for the comparator and the frequency of moderate and severe solicited systemic adverse events was 26% for Z-1018 arms and 43% for the comparator;
"With these promising data, we have a better understanding of the potential for a CpG 1018 adjuvanted shingles vaccine to reduce post-injection reactions to improve patients' experience compared with the currently commercialized shingles vaccine," said Dr.
Based on these initial data, the Company intends to advance its shingles vaccine candidate with CpG 1018 adjuvant into a Phase 1-2 study in early 2024 to expand on these results and to evaluate various dose levels of
DV2-ZOS-01 is a randomized, active-controlled, dose-escalation, multi-center Phase 1 clinical trial to evaluate the safety, tolerability, and immunogenicity of investigational herpes zoster (shingles) vaccine utilizing a commercially available gE plus CpG 1018 adjuvant (Z-1018) with and without alum compared to Shingrix® in approximately 150 healthy volunteers between the ages of 50 and 69 years of age.

HEPLISAV-B is indicated for the prevention of infection caused by all known subtypes of hepatitis B virus in adults aged 18 years and older.
Do not administer HEPLISAV-B to individuals with a history of a severe allergic reaction (e.g., anaphylaxis) after a previous dose of any hepatitis B vaccine or to any component of HEPLISAV-B, including yeast.
Appropriate medical treatment and supervision must be available to manage possible anaphylactic reactions following administration of HEPLISAV-B.
Immunocompromised persons, including individuals receiving immunosuppressant therapy, may have a diminished immune response to HEPLISAV-B.
Hepatitis B has a long incubation period. HEPLISAV-B may not prevent hepatitis B infection in individuals who have an unrecognized hepatitis B infection at the time of vaccine administration.
The most common patient-reported adverse reactions reported within 7 days of vaccination were injection site pain (23% to 39%), fatigue (11% to 17%), and headache (8% to 17%).
This press release contains "forward-looking" statements, including statements regarding expected or anticipated financial performance, including market share, revenue and profitability, potential U.S. market for hepatitis vaccines, establishing CpG 1018 as a leading adjuvant, future sales of CpG 1018 or HEPLISAV-B or other product candidates, anticipated timing and progress of the DV2-ZOS-01 clinical trial and related data analysis, data preparation and publication, the timing of a Phase 1/2 trial for the shingles vaccine candidate or other candidates. Actual results may differ materially from those set forth in this press release due to the risks and uncertainties inherent in our business, including, the risk that HEPLISAV-B may not become the standard of care adult hepatitis B vaccine in the
