About this study

Official title: VRC 601: A Phase I, Open-Label, Dose-Escalation Study of the Safety and Pharmacokinetics of a Human Monoclonal Antibody, VRC HIVMAB060-00-AB (VRC01), With Broad HIV-1 Neutralizing Activity, Administered Intravenously or Subcutaneously to HIV-Infected Adults

This is the first clinical trial of the VRC-HIVMAB060-00-AB (VRC01) monoclonal antibody. VRC01 is a broadly neutralizing antibody directed against HIV. This is a dose-escalation study to examine safety, tolerability, dose and pharmacokinetics of VRC01. The hypothesis is that VRC01 will be safe for administration to HIV-1 infected adults by the intravenous (IV) and subcutaneous (SC) routes and will not elicit hypersensitivity reactions. Samples will be collected to learn if VRC01 is detectable in mucosal secretions and blood of participants and how long VRC01 can be detected in the blood after it is given.

Between 15 and 25 HIV-1 infected adults, ages 18-70 years will be enrolled. There are 4 dose escalation groups for IV administration; the doses are 1 mg/kg, 5 mg/kg, 20 mg/kg and 40 mg/kg. There is 1 group for SC administration at 5 mg/kg. Each group is expected to include at least 3 participants. Each participant will receive two infusions of VRC01 with about 1 month between doses. Infusions are administered in an inpatient unit and an overnight stay at the NIH Clinical Center is required. No more than one subject per day per group will receive a first infusion of the VRC01 product by the IV route and no more than one subject per week will receive a first infusion of the product by the SC route. Study participation lasts for 24 weeks. Participant health and effect on CD4 count and HIV viral load will be monitored. Samples will be collected and stored for research purposes.

Read the detailed description

This is the first clinical trial of the VRC-HIVMAB060-00-AB (VRC01) monoclonal antibody. VRC01 is a broadly neutralizing antibody directed against HIV. This is a dose-escalation study to examine safety, tolerability, dose and pharmacokinetics of VRC01. The hypothesis is that VRC 01 will be safe for administration to HIV-1- infected adults by the intravenous (IV) and subcutaneous (SC) routes and will not elicit hypersensitivity reactions. Samples will be collected to learn if VRC01 is detectable in mucosal secretions and blood of participants and how long VRC01 can be detected in the blood after it is given.

Up to 30 HIV-1 infected adults will be enrolled. Adult 18-60 years old will participate in the dose escalation part of the study. There are 4 dose escalation groups for IV administration; the doses are 1 mg/kg, 5 mg/kg, 20 mg/kg and 40 mg/kg. There is 1 group for SC administration at 5 mg/kg. Each dose escalation group is expected to include at least 3 participants. Each participant during the dose escalation part of the study will receive two infusions of VRC01 with about 1 month between doses, with infusions administered in an inpatient unit and an overnight stay at the NIH Clinical Center required. No more than one subject per day per group will receive a first infusion of the VRC01 product by the IV route and no more than one subject per week will receive a first infusion of the product by the SC route. Study participation lasts for 24 weeks for participants who receive two doses. After the dose escalation is completed, about 10 HIV-infected adults, ages 18-70 years old, with detectable viral load will be enrolled to receive one dose of VRC01 at 40 mg/kg IV with follow-up for 12 weeks. Participant health and effect on CD4 count and HIV viral load will be monitored. Samples will be collected and stored for research purposes.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing VRC-HIVMAB060-00-AB in people with HIV-1 Infection and Neutralizing Antibody, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.

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 26 inclusion and 11 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 17 Dec 2019. 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 United States. 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 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?

Adverse events of all severities (time frame: From first product admin thru 56 days after last admin). 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 NCT01950325, which also lists 5 linked publications.

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 17 Dec 2019.
