About this study

Official title: Phase-I Open Label, Dose-escalation Clinical Trial to Evaluate the Safety, Tolerability and Immunogenicity of Chikungunya Vaccine in Healthy Adults of 18 to 50 Years Age

Chikungunya vaccine is an inactivated virus vaccine. There will be three study arms and subjects will be vaccinated in a dose escalation manner.In each arm, vaccine will be administered on Day 1, Day 29, and Day 57. Vaccine will be administered through intramuscular route.

Read the detailed description

This is an open label phase I study for assessing the safety, tolerance and immunogenicity of 3 escalated doses of the test vaccine, BBV87. The study design has four treatment groups - 3 test groups and a control placebo group with 15 subjects in each group. However, the groups will be divided into three study arms: each arm will have 15 subjects of the test vaccine group and 5 subjects of the placebo group. The randomization will be done in a way that allots 5 subjects of the placebo group to each test dose group. All subjects will be screened (via medical history, physical examination and laboratory investigations) to establish the eligibility criteria. This includes negative antibodies, CHIKV IgG, by ELISA method. The test vaccine and placebo will be administered as 3 doses at 28 days interval on day 1±2, 29±2, and 57±2. Vaccine administration will be performed as an in-patient procedure. Subjects will be admitted in CPU 24 hrs prior to vaccine administration, and will be shifted to MICU for vaccination and observed for 48 hrs; and will be discharged upon completion of all clinical monitoring procedures. Laboratory and biochemical tests will be performed as part of clinical monitoring before discharge, and 24 hrs after vaccine administration. Following vaccination, all participants will be monitored throughout the study period for adverse events with daily telephone contacts (for 7 days after each vaccine, and then weekly), interim clinic visits, subject diary cards, and haematological \& biochemical laboratory tests.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Inactivated Chikungunya virus vaccine 20 mcg, Inactivated Chikungunya virus vaccine 30 mcg and Inactivated Chikungunya virus vaccine 10 mcg in people with Chikungunya, run by Bharat Biotech International Limited at 4 sites 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 8 inclusion and 25 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 28 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 4 sites 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 post each dose (time frame: Within 24 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 28 Oct 2020.
