Kaletra Monotherapy in HIV/HCV Co-infected Subjects

• Status: Completed
• Trial end date: 2011-04-01
• Target enrollment: 0
• Participant gender: All

Summary

The study has been designed to test the hypothesis that in patients co-infected with HIV and HCV who exhibit maximal virologic suppression on a double class antiretroviral (ARV) regimen, including two Nucleoside Reverse Transcriptase Inhibitors (NRTIs) and a Non-nucleoside Reverse Transcriptase Inhibitors (NNRTI) or a Protease Inhibitor (PI) (boosted or not with ritonavir), simplification of highly active antiretroviral therapy (HAART) to Kaletra® monotherapy will represent a viable strategy without any negative impact on the virologic control of HIV infection.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Ottawa Hospital Research Institute
• Collaborator: Abbott

6. Subject's serum AST and ALT levels must be <5 times normal (grade 2 or less) at the start of the study.

7. Subject must not harbour viral strains that are resistant to Kaletra® at the start of the study.

8. Subject has a Karnofsky Score 70 or greater.

9. If female, subject must have a negative pregnancy test and agree to use, for the duration of the study, a barrier method of birth control that has a history of proven reliability as judged by the investigator.

Exclusion Criteria

1. Subject has active hepatitis B (HbsAg +).

2. Subject has a history of substance abuse or psychiatric illness that could preclude compliance with the protocol.

5. Subject has received an investigational drug within 30 days prior to the initiation of study dosing.

6. Subject exhibits viral strains that are resistant to lopinavir.

7. Subject is receiving systemic chemotherapy.

8. The subject, in the opinion of the principal investigator, is unlikely to comply with the study protocol or is unsuitable for any other reason.
