Model description
This is a Phase 1, randomized, partially-blind (observer-blind), placebo controlled, single dose ascending study in healthy adults. For the Cohort 1 (Initial Safety Cohort), no placebo control will be used and hence, blinding is not applicable. There will be 4 dose levels. The proposed doses to be studied are; 1 mg/kg, 3 mg/kg, 12 mg/kg and 25 mg/kg. Total of 40 participants will be dosed and followed till Day 84 from dosing.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Dengushield 1 mg/kg (Cohort 1) intravenous, Dengushield 3 mg/kg (Cohort 2) intravenous and Dengushield 7 mg/kg (Cohort 3) intravenous in people with Phase 1 and Dengue, run by Serum Institute of India Pvt. Ltd. at 1 site in Australia.

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 12 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 18 Feb 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 Australia. 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?

The proportion of participants with post-injection/ infusion adverse events (AEs) including hypersensitivity reaction, anaphylactic reaction and other AEs occurring within 4 hours of the start of dosing (time frame: 4 hours post administration of drug). 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?

On the ClinicalTrials.gov record for NCT03883620, which also lists 1 linked publication.

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 18 Feb 2020.
