About this study

Official title: Drug-Drug Interaction Study to Assess the Effects of Steady-State Darunavir/Ritonavir on Steady-State Pitavastatin in Healthy Adult Volunteers

This is a Phase 4, single center, open label, fixed-sequence, multiple dose, 2-way drug-drug interaction study.

Read the detailed description

This is a Phase 4, single center, open label, fixed-sequence, 2-way drug-drug interaction study.

Each subject will qualify for entry into the study not more than 30 days before admission into the clinical unit. Subjects will check into the clinical unit on Day -1 for baseline assessments. There will be 1 treatment period, with each subject receiving a once daily dose of pitavastatin 4 mg on Days 1 through 5 and Days 12 through 16 and a once daily dose of darunavir/ritonavir 800 mg/100 mg on Days 6 through 16. On Days 1 through 4, 6 through 10, and 12 through 15, study drug will be administered 30 minutes before a standard breakfast. On Days 5, 11, and 16, subjects will fast at least 8 hours before receiving study drug and remain fasted for 4 hours after dosing.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Pitavastatin (NK-104) and Darunavir/Ritonavir (Prezista) in people with Healthy, run by Kowa Research Institute, 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 5 inclusion and 4 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 13 Jul 2012. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 15 Mar 2012). 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?

NK-104 AUC (time frame: 16 Days). 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 NCT01422369, 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 13 Jul 2012.
