Official title

A Phase I/II, Randomized, Open-Label Study of the Safety and Pharmacokinetics of Indinavir + Ritonavir Therapy in HIV-Infected Subjects Failing Amprenavir, Nelfinavir, Saquinavir, or Nelfinavir/Saquinavir Combination Therapy

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In this study, the protease inhibitors indinavir (IDV) and ritonavir (RTV) will be studied in patients who have high levels of virus while taking other protease inhibitors. The purpose of this study is to see how the body takes in, distributes, and gets rid of IDV and RTV. This study will also look at any side effects that IDV or RTV causes. IDV is an effective anti-HIV drug, but it can be difficult for patients to take. For IDV to work against HIV, it must be taken 3 times a day at a high dose and with a certain diet. Doctors believe IDV may be easier to take if it is given with RTV. Patients who take IDV and RTV together may be able to take IDV only twice a day and at a lower dose. This study will gather information about the safety and side effects of using IDV and RTV together.
