About this study

Official title: An Open-Label, Multicenter, Mechanism Validation Study to Evaluate the Safety, Efficacy and Tolerability of KP-1461 as Monotherapy for 124 Days in Antiretroviral-experienced, HIV-1-infected Subjects

The primary purpose of the study is to investigate the safety and efficacy of KP-1461 given every 12 hours for 124 days to HIV+ patients who have failed multiple antiretroviral regimens.

Read the detailed description

KP-1461 is a prodrug of KP-1212 triphosphate, a unique nucleoside that is incorporated into the HIV viral genome resulting in an accumulation of nucleic substitutions that interfere with viral replication. The study is designed to investigate the safety and antiviral activity for 124 days in antiretroviral-experienced HIV-1-infected subjects. By inducing additional mutagenic events in the viral genome, viral decay accelerators such as KP-1212 may force the virus to exceed the threshold of nonviability.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing KP-1461 in people with HIV Infections, run by Koronis Pharmaceuticals. at 31 sites in 2 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 5 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: stopped early, as of the sponsor's last update on 7 Nov 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 31 sites in United States, Puerto Rico. 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 (reason given: Corroboration of supporting in vitro data \- Data successfully corroborated 2009). 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?

To evaluate the safety and tolerability of KP-1461 for 124 days in treatment-experienced, HIV-1-infected subjects. (time frame: 124 days). 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 7 Nov 2011.
