Read the detailed description

A phase 1, multicenter, double-blind, placebo-controlled, randomised (intra group) clinical trial to evaluate the safety, tolerability and immunogenicity of two-doses of three-sequentially escalating cohort (2.5 µg, 5 µg and 10 µg) of BBV121 (inactivated adsorbed Zika Virus Vaccine) compared with Placebo (Alum) administered intramuscularly on Day 0 and 28 in healthy adult Dengue Sero-Negative (Group 1) and Dengue Sero-Positive (Group 2) male and female volunteers.

Participants will be assigned to sequential escalating dose level groups to receive vaccinations at 2.5 µg, 5 µg, or 10 µg or Placebo on Day 0 and 28 with follow-up for 12 months from initial administration of the investigational product.

Immunogenicity testing on Day 0, 28 and 56, and post-study at the end of Month 6, 9 and 12 after the initial administration of the investigational product.

Safety tests (laboratory and clinical investigations) will be done during Screening, Day 0, 28, 56, and post-study at Month 6, 9 and 12 months after the initial administration of the investigational product.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BBV121 in people with Zika Virus Infection, run by Bharat Biotech International Limited at 1 site in India.

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 22 inclusion and 38 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: finished, as of the sponsor's last update on 22 Oct 2020. 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 India. 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 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.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Occurrence of adverse events and Serious Adverse events (time frame: Within 2 hrs). 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 22 Oct 2020; AzTrials last refreshed its copy on 3 Nov 2026.
