Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 42 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2001-08-31
• Study Completion Date: 2003-10-31

Brief Summary

The purpose of this study is to determine the antiviral activity, safety and tolerability of 14 days of different doses of TMC114 to treat HIV-1 positive patients whose condition is failing on a current treatment regimen that includes a protease inhibitor (PI) (a medication used to reduce the amount of HIV virus in the blood).To be considered for the study, patients must have a documented resistance to at least 2 of the current PIs. Pharmacokinetics and pharmacodynamics of TMC114 will also be assessed.

Detailed Description

This is a Phase lla open-label (all people involved know the identity of the treatment), randomized (study drug assigned by chance), controlled (the patients of the control group continue the failing regimen), dose-finding study to determine the antiviral activity, safety and tolerability of a 14-day treatment with TMC114 (a protease inhibitor) for treatment of human immunodeficiency virus type 1 (HIV-1) positive patients who are considered resistant to (failing to improve on) 2 or more protease inhibitors (PIs). Sixty HIV-1 positive patients, who are resistant to multiple PIs as confirmed by specialized testing (virtual phenotyping) and who are currently failing to improve on a treatment regimen that contains a PI, will be randomly assigned to one of 5 treatment groups. Those randomized to the control group will continue their current therapy (consisting of PIs and Nucleoside Reverse Transcriptase Inhibitor(s) (NRTIs)). Those randomized to the TMC114 treatment groups will receive the study drug as a substitute for all the PIs in the current failing treatment regimen at the following dose levels: 400 or 800 mg twice a day, or 800 or 1200 mg three times a day for 13 days followed by a single dose on day 14. The dose of the NRTIs (NRTIs are drugs that suppress replication of retroviruses) will remain unchanged until the end of the treatment period. The trial will involve a screening period of maximum three weeks, a 7-day run-in period (the period of time before study start when no treatment is given), a 14-day treatment period, followed by a 6- week follow-up period. The maximal trial duration will thus be twelve weeks. Primary objective is to determine the antiviral activity of TMC114 as well as the pharmacokinetics (how the drug is absorbed in the body, distributed within the body and how it is removed from the body over time) and pharmacodynamics (the study of the action of effects a drug has on the body) will also be assessed over the 2 week period.Safety will be followed at regular intervals during treatment and follow-up period. Safety assessments consist of regular lab assessments, ECG recording, vital signs, physical examination, body weight and Body Mass Index. Observation of and interview for adverse events will be done daily during the first week of treatment, every second day during the 2nd week of treatment, and at week 1, 3 and 6 of the follow-up period. In addition an Independent Data Monitoring Committee will evaluate the study data at regular intervals. Patients will be randomly assigned to one of 5 treatment groups: 400 or 800 mg twice a day for 13 days followed by a single dose on day 14, or 800 or 1200 mg three times a day for 13 days followed by a single dose on day 14. Patients randomized to the control group will continue their current therapy consisting of protease inhibitors (PIs) and Nucleoside Reverse Transcriptase Inhibitors (NRTIs).
