About this study

Official title: Phase IIB, Randomized, Multicenter, Parallel Group, Study to Evaluate the Safety, Pharmacokinetics and Antiviral Effect of Four Blinded Dosing Regimens of GW640385X/Ritonavir Compared to Open-label Current PI Therapy in HIV-1 Infected, Protease Inhibitor Experienced Adults for 2 Weeks With Long-term Assessment (>48 Weeks) of Safety, Pharmacokinetic and Antiviral Activity of Selected 385/RTV Dosing Regimen(s) vs. a Ritonavir-boosted, Protease Inhibitor Containing Regimen

This is a two phase study (randomised and non-randomised phase). The randomised phase will initially examine 4 blinded doses of GW640385 boosted with rtv (with continuation of current background therapy) in comparison to an ongoing, open-labeled rtv-boosted protease inhibitor (PI) regimen for 15 days. At the Day 15 visit, all subjects will optimize background therapy. Additionally, subjects receiving the lowest dose of GW640385 will be re-randomised to one of the higher doses and subjects in the control arm will receive a new rtv-boosted PI based on resistance testing at screening. Subjects will remain in the randomized phase on one of these 4 continuing treatment arms for at least 48 weeks. An interim analysis will occur during the randomised phase to select for a dose of GW640385 to evaluate further in Phase III studies. After dose selection subjects will move to the non-randomised phase of the study. In the non-randomised phase subjects who are receiving GW640385 will be assigned to final selected dose for assessment of long term safety, tolerability, pharmacokinetics, and antiviral activity.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Physician determined comparator PI + ritonavir and GW640385 + ritonavir in people with Infection, Human Immunodeficiency Virus I and HIV-1 Infection, run by ViiV Healthcare at 70 sites in 11 countries.

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 5 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: stopped early, as of the sponsor's last update on 30 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 70 sites in United States, France, Italy, Canada, Germany and 6 more countries. 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 was stopped early. Results are not available in the source record.

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?

Time averaged change in plasma HIV-1 RNA over 16 wks. 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?
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 30 May 2017.
