About this study
Official title: A Phase 2b, Randomized, Double-Blind, Placebo-Controlled Clinical Trial of Observed Systemic, Long-Acting, Anti-HIV Treatment With a Monoclonal Anti CCR5 Antibody (PRO 140) as an Adjunct to a New, Optimized, Oral Antiretroviral Regimen in HIV-Infected Injection Drug Users With Viral Rebound and Documented Poor Adherence to the Previous Antiretroviral Regimen
PRO 140 2102 is a phase 2b, national, multicenter, randomized, double-blind, placebo-controlled study in order to evaluate the safety and efficacy of PRO 140 (anti-CCR5 monoclonal antibody) administered subcutaneously as an adjunct to a new, optimized, oral antiretroviral regimen in HIV-infected injection drug users with viral rebound and documented poor adherence to the previous antiretroviral regimen.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing PRO 140 in people with HIV, run by CytoDyn, Inc. 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 4 inclusion and 3 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The record says: withdrawn, as of the sponsor's last update on 2 Feb 2017. 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. 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 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The study was withdrawn before enrolling participants, so there are no results.
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?
Specific measure that will be used to determine the effect of the interventions: Percentage of subjects without virologic failure at week 24. (time frame: 24 Weeks). 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 2 Feb 2017.
