Interactions of HIV Protease Inhibitors and Methadone in HIV-Infected Patients
A Phase 1 study testing Ritonavir, Saquinavir and Methadone hydrochloride in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 7 sites in United States.
Trial summary
The purpose of this study is to see if it is safe to combine methadone with two HIV protease inhibitors (PIs), ritonavir (RTV) and saquinavir (SQV), in HIV-infected patients not currently taking PIs. This study will measure the interactions between methadone and the PIs. Read more about this study

About this study
Official title: The Effect of HIV Protease Inhibitors on the Stereospecific Metabolism of Methadone in HIV-Infected Subjects
The purpose of this study is to see if it is safe to combine methadone with two HIV protease inhibitors (PIs), ritonavir (RTV) and saquinavir (SQV), in HIV-infected patients not currently taking PIs. This study will measure the interactions between methadone and the PIs.
Methadone is used treat addicts and to treat severe pain. In order to find the safest way to use methadone with PIs, it is important to evaluate how they interact.
Read the detailed description
Methadone is extensively used in the maintenance treatment of addicts and in the management of severe pain. In order to use methadone with HIV protease inhibitors correctly, it is important to evaluate and quantify interactions between the protease inhibitors and methadone.
Patients receive their usual daily dose of methadone followed with ritonavir and saquinavir, respectively, twice a day. Patients are evaluated on Day 4 for safety and tolerance, and their ritonavir dose is increased. On Day 8 patients are evaluated for a steady-state level of methadone. After 2 weeks of the protease inhibitor therapy, they return for methadone pharmacokinetic sampling at Day 15 over 24 hours. Both protease inhibitors and methadone are administered on Day 15 on an inpatient basis. On Day 30, patients are assessed for safety and tolerance.

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 12 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 4 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites 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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00000906, 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 4 Nov 2021.
