HIV InfectionsPhase 1/2NCT00411996
The Pharmacokinetics and Safety of IDV/r With NRTIs in HIV/TB Co-infected Patients Receiving Rifampicin
A Phase 1/2 study testing indinavir/ritonavir in people with HIV Infections and Tuberculosis, run by The HIV Netherlands Australia Thailand Research Collaboration at 1 site in Thailand.
Trial summary
We believe that there is a strong rationale for the study of IDV/r 600/100 bid as a boosted-PI combination that, in the presence of RMP, is able to produce a satisfactory PK profile associated with adequate antiretroviral potency, tolerability and efficacy. Read more about this study

About this study
Official title: The Pharmacokinetics and Safety of Ritonavir-boosted Indinavir 600/100mg Bid Combined With NRTIs in ARV naïve HIV/TB Co-infected Patients Receiving Rifampicin Containing Anti-tuberculosis Therapy
We believe that there is a strong rationale for the study of IDV/r 600/100 bid as a boosted-PI combination that, in the presence of RMP, is able to produce a satisfactory PK profile associated with adequate antiretroviral potency, tolerability and efficacy.
Read the detailed description
The fixed-dose combination of d4T+3TC+NVP (GPOvir) has been widely used in Thailand since June 2002. The prevalence of NNRTI resistance has increased since 2005. Efavirenz-based antiretroviral therapy (ART) is preferred in patients with TB/HIV receiving rifampin-containing TB regimens. However, efavirenz cannot be used in the context of NNRTI failure, intolerance or toxicity. The optimal ART in populations receiving rifampicin remains unknown. Rifabutin, which is recommended in combination with a boosted protease inhibitor (PI/r) is expensive and not available in Thailand and other developing countries. Ritonavir-boosted indinavir (IDV/r) is potent and the cheapest boosted PI available in Thailand. If IDV/r in combination with rifampin demonstrates suitable pharmacokinetics and is well tolerated, this regimen might prove useful and could be widely implemented. However, high rates of gastrointestinal and renal toxicity have been demonstrated in Thai patients receiving standard doses of IDV/r 800/100 BID. We believe that there is a strong rationale to study if IDV/r 600/100 BID in combination with rifampin is able to produce a satisfactory pharmacokinetic profile, with antiretroviral potency, tolerability and efficacy.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing indinavir/ritonavir in people with HIV Infections and Tuberculosis, run by The HIV Netherlands Australia Thailand Research Collaboration at 1 site in Thailand.
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 10 inclusion and 7 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 17 Jul 2020. 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 Thailand. 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 combined 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.
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 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.
What does the primary outcome measure?
pharmacokinetics of ritonavir-boosted indinavir 600/100mg bid in combination with rifampicin-containing anti-TB therapy. (time frame: 2 weeks). 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 NCT00411996, 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 17 Jul 2020; AzTrials last refreshed its copy on 8 Nov 2026.
