What is being measured

The primary outcome is the main question the study is designed to answer.

  1. phase 1: Incidence and intensity of solicited adverse events (AEs)

    Measured: within 14 days after each vaccination

  2. phase 1: Incidence and intensity of unsolicited AEs

    Measured: within 30 days after each vaccination

  3. phase 2: Geometric mean concentration (GMC) and seroconversion rate of antigen-specific antibody

    Measured: at 30 days after full vaccination

Secondary outcomes (11)
  1. phase 1: Geometric mean titer (GMT)/ GMC, Geometric mean fold increase (GMI), and seroconversion rate of antigen-, and VZV-specific antibody

    Measured: at 30 days after the first vaccination, before the second vaccination, and at 30 days after full vaccination

  2. phase 1:Frequency and response rate of CD4+ T cells with antigen-specific TNF-α and/or IFN-γ and/or IL-2 and/or CD40L secretion/expression as determined by intracellular cytokine staining (ICS)

    Measured: at 30 days after the first vaccination, before the second vaccination, and at 30 days after full vaccination

  3. phase 1: Incidence of Serious adverse events (SAEs) and Adverse events of special interest (AESIs)

    Measured: during the study (from the first vaccination to 12 months after full vaccination)

  4. phase 1: Incidence and intensity of abnormal laboratory tests indicators

    Measured: 3 days after each vaccination

  5. phase 2: GMI of antigen-specific antibody

    Measured: at 30 days after full vaccination

  6. phase 2: GMC, GMI, and seroconversion rate of antigen-specific antibody

    Measured: before the second vaccination, and at 6 months, 12 months and 24 months after full vaccination

  7. phase 2: GMT/GMC, GMI, and seroconversion rate of VZV-specific antibody

    Measured: before the second vaccination, and at 30 days, 6 months, 12 months and 24 months after full vaccination

  8. phase 2: Frequencies and response rate of CD4+ T cells with antigen-specific TNF-α and/or IFN-γ and/or IL-2 and/or CD40L secretion/expression as determined by ICS

    Measured: before the second vaccination, and at 30 days, 6 months, 12 months and 24 months after full vaccination

  9. phase 2: Incidence and intensity of solicited AEs

    Measured: within 14 days after each vaccination

  10. phase 2: Incidence and intensity of unsolicited AEs

    Measured: within 30 days after each vaccination

  11. phase 2: Incidence of SAEs and AESIs

    Measured: from the first vaccination to 12 months after full vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Recombinant Herpes Zoster Vaccine (SCTV04C) Low-Dose, Recombinant Herpes Zoster Vaccine (SCTV04C) High-Dose and Shingrix® in people with Herpes Zoster, run by Sinocelltech Ltd. at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 30 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Dongyang Gao, Doctor (+86-010-58628288-9137, dongyang_gao@sinocelltech.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

phase 1: Incidence and intensity of solicited adverse events (AEs) (time frame: within 14 days after each vaccination). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jan 2025.
