A Study to Compare the Safety and Effectiveness of Indinavir Combined With Stavudine and Lamivudine
A Phase 2 study testing L-756423, Indinavir sulfate and Lamivudine in people with HIV Infections, run by Merck Sharp & Dohme LLC at 16 sites in United States.
Trial summary
This study will see how safe and effective against HIV the drugs L-756423 plus indinavir (IDV) are compared to just IDV when taken with stavudine (d4T) and lamivudine (3TC). The study will also see whether taking 1 large dose of L-756423/IDV once a day is as safe and effective as taking 2 smaller doses twice a day. Read more about this study

About this study
Official title: A Multicenter, Double-Blind, Randomized Pilot Study to Compare the Safety and Activity of L-756423/Indinavir, 1600/800 Mg Qd or 800/400 Mg Bid Versus Indinavir, 800 Mg q8h, All in Combination With Stavudine and Lamivudine
This study will see how safe and effective against HIV the drugs L-756423 plus indinavir (IDV) are compared to just IDV when taken with stavudine (d4T) and lamivudine (3TC). The study will also see whether taking 1 large dose of L-756423/IDV once a day is as safe and effective as taking 2 smaller doses twice a day.
Read the detailed description
Patients are randomized to 1 of 4 treatment arms. In Group 1, patients receive a dose of L-756423/IDV once daily plus IDV placebo. In Group 3, patients receive a lower dose of L-756423/IDV twice daily (with the daily dosage equaling that of Group 1) plus IDV placebo. In Groups 2 and 4, patients receive equal dosages of IDV plus L-756423/IDV placebo. In all 4 groups L-756423 and IDV are blinded to the investigator and patient. All groups receive open-label d4T and 3TC. Patients routinely undergo a physical exam and have blood and urine tests to ensure the drugs' safety and tolerability, which will be evaluated by tabulation of adverse events and clinical assessment of laboratory data. In addition, CD4+ T cell and plasma viral RNA levels are measured to quantify the drugs' antiretroviral activity.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing L-756423, Indinavir sulfate and Lamivudine in people with HIV Infections, run by Merck Sharp & Dohme LLC at 16 sites 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 2 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: paused, as of the sponsor's last update on 24 Jun 2005. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 16 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 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?
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.
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 24 Jun 2005.
