Safety Study of Tipranavir Co-administered With Low-dose Ritonavir (TPV/r) in Patients With Advanced HIV-1 Infection and Limited Treatment Options

Boehringer Ingelheim255 enrolled

Overview

This study evaluated the safety and tolerability of tipranavir to improve treatment options for HIV type 1-infected patients who have been previously treated and whose treatment is no longer effective.

The purpose of this open label study is to assess the safety and tolerability of tipranavir co-administered with low-dose ritonavir (500 mg tipranavir/200 mg ritonavir BID) in HIV-1 infected patients who are triple antiretroviral class experienced with at least two previous PI-containing regimens. The safety assessment will be performed by evaluating: * The frequency of treatment-emergent adverse events (AEs) , all serious adverse events (SAEs), and additional safety laboratory parameters. * The occurrence of PI class-specific AEs, such as hemorrhage, dyslipidemia, hepatic events, hyperglycemia, pancreatitis, and rash. The efficacy assessment will be performed by evaluating: * The quantity of HIV-1 RNA * The CD4 cell count.
