About this study
Official title: Lopinavir/r Plus Saquinavir Salvage Therapy in HIV-infected Children With NRTI and/or NNRTI Failure: PK and Two-year Treatment Follow up
To evaluate the pharmacokinetics (PK) of LPV/r with saquinavir in HIV-1 infected children. To evaluate treatment response (clinical, immunological and virological) to LPV/r, SQV in Thai children.
Read the detailed description
The PK and 24 week data has been published in Pediatric Infectious Diseases Journal. It showed that plasma drug concentrations of saquinavir, lopinavir and ritonavir were at the higher limits of expected ranges for adult treatment at approved dosages (1000/100 mg BID for saquinavir, 400/100 mg BID for lopinavir/r). The regimen was well tolerated and showed significant CD4 rise and VL decline at 48 weeks.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Lopinavir/r plus saquinavir in people with HIV Infections, run by The HIV Netherlands Australia Thailand Research Collaboration at 3 sites 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 6 inclusion and 14 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 27 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites 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 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?
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?
Intensive 0-12h PK sampling for plasma levels of LPV and SQV, and blood sampling. CD4 viral load safety lab every 3 months. (time frame: 96 week). 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 NCT00476359, which also lists 6 linked publications.
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 27 Mar 2015.
