About this study

Official title: A Phase II, Pilot, Randomized, Open-Label, Single-Center Study to Evaluate Immunogenicity, Safety and Booster Response of 3 Full Intramuscular Doses Versus 3 Half Intramuscular Doses Versus 3 Intradermal Doses Versus 2 Intradermal Doses of PCEC Rabies Vaccine Administered Concomitantly With Japanese Encephalitis Vaccine as a Pre-Exposure Regimen in 12 to 18 Months Old Toddlers in Thailand.

This study evaluated the safety and immunogenicity of rabies vaccine and Japanese encephalitis vaccine in toddlers. All children developed adequate immune responses. Rabies vaccination with PCECV did not interfere with the antibody response to Japanese encephalitis vaccine. The rabies vaccine PCECV and Japanese encephalitis vaccine are safe and immunogenic when administered concomitantly to toddlers.

Being tested
Three 1 mL doses of Rabies vaccine and two JE vaccine, Three 0.5 mL doses of Rabies vaccine and two JE vaccine, Three 0.1mL doses of Rabies Vaccine and two JE vaccine, Two 0.1mL doses of Rabies vaccine and two JE vaccine, Two doses of JE vaccine
Keywords
rabies vaccination, pre-exposure prophylaxis, rabies virus neutralizing antibody
Medical subject headings

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Three 1 mL doses of Rabies vaccine and two JE vaccine, Three 0.5 mL doses of Rabies vaccine and two JE vaccine and Three 0.1mL doses of Rabies Vaccine and two JE vaccine in people with Rabies and Japanese Encephalitis, run by Novartis at 1 site in Thailand.

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 4 inclusion and 14 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 10 Jun 2008. 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 Thailand. 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. 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 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?

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?

Rabies virus neutralizing antibody concentrations (time frame: 2 years). 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 10 Jun 2008.
