About this study

Official title: Safety and Pharmacokinetic Evaluation of Zika Virus Immune Globulin in Healthy Volunteers

Currently, there are no licensed therapeutics against Zika virus infection. Due to this unmet medical need, Zika Virus Immune Globulin (ZIKV-IG) is being developed as a therapeutic intervention against Zika virus infection. In this first-in-human study, evaluation of ZIKV-IG safety and pharmacokinetics (absorption, metabolism and excretion) will be conducted in healthy adult volunteers.

Read the detailed description

This study will be evaluating safety and pharmacokinetics (PK) of one dose level of ZIKV-IG (50 mL) in healthy adult volunteers. The study is a single-center, double-blind, randomized and placebo-controlled design. The primary objective is to assess safety of intravenously (IV) administered ZIKV-IG, while the secondary objective is to determine the PK profile of ZIKV-IG in healthy adult volunteers.

There will be a total of 30 subjects enrolled into the study; dosing of the first six subjects will be staggered over three separate days, wherein two subjects per day will be randomized 1:1 to either receive 50 mL of placebo IV or 50 mL of ZIKV-IG IV (the total amount of gamma immune globulin [IgG] protein from a single 50mL dose is 4.65g). After the first six subjects are dosed, the remaining 24 subjects will be randomized 2:1 to receive either ZIKV-IG or placebo. A safety monitoring committee will review safety data (collected up to 3 days post-dosing) of the first 12 dosed subjects prior to dosing of the remaining 18 subjects. Overall, there will be 19 subjects randomized to receive ZIKV-IG and 11 subjects randomized to receive placebo on Day 1. On Day 1 (post-dose at 1 hour, 3 hours, 8 hours) and Day 2, safety and PK assessments will be conducted while the subjects are in the Phase 1 clinic. After the discharge on Day 2, the subjects will come back to the clinic for safety and PK assessments on Days 3, 4, 6, 8, 10, 12, 15, 22, 29, 43, 57 and 85. Total study duration for each subject will be up to 4 months (from screening to Day 85).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Zika Virus Immune Globulin (ZIKV-IG) in people with Zika Virus Infection and Zika Virus Disease, run by Emergent BioSolutions at 1 site in Canada.

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 15 inclusion and 28 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 Mar 2024. 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 Canada. 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?

Yes. Results are posted in the registry (first posted 13 Jul 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Subjects With Adverse Events. (time frame: Up to Day 85). 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 NCT03624946, 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 Mar 2024.
