NCT00146328 ↗	Rollover Trial Safety and Tolerability of Combination Tipranavir and Ritonavir Use in HIV 1 Infected Subjects	Completed	Boehringer Ingelheim	Phase 2/Phase 3	2001-04-01	The objective of this study is to determine the long term safety and tolerability of multiple oral doses of tipranavir (Aptivus) and ritonavir with a focus on the long term safety of the development dose (500 mg tipranavir/200 mg ritonavir BID) when administered with other antiretroviral medications.
NCT00344123 ↗	Pharmacokinetic (PK) Study of Single-dose Rosuvastatin and Tipranavir/Ritonavir in Healthy Subjects	Completed	Boehringer Ingelheim	Phase 1	2007-02-01	Tipranavir (TPV) plus ritonavir (RTV) is indicated for use as part of an antiretroviral treatment regimen for resistant HIV-1 infection in adult patients. Since significant cholesterol and triglyceride elevations are commonly reported during TPV/RTV treatment, effective treatment strategies are critical to prevent long-term cardiovascular events. Rosuvastatin, a potent 3-hydroxy-3-methylglutaryl-coenzyme (HMG-CoA) reductase inhibitor, is unlikely to interact with TPV/RTV since it is not extensively metabolized, however, a formal drug interaction study is needed before this combination can be recommended. This study will examine the pharmacokinetic interactions between tipranavir/ritonavir (TPV/RTV [TPV/r] 500 mg/200 mg twice daily [B.I.D]) and single dose rosuvastatin when the two are co-administered to healthy adult volunteers. The investigators hypothesize that if tipranavir 500 mg is co-administered with low-dose ritonavir 200 mg and rosuvastatin (10 mg) no significant clinical interaction will occur.

NCT00624195 ↗	Clinical Trial of CNS-targeted HAART (CIT2)	Completed	National Institute of Mental Health (NIMH)	Phase 2/Phase 3	2007-03-01	CIT2 is a strategy for targeting HAART (Highly Active Antiretroviral Therapy) to the CNS (Central Nervous System) in patients with HIV associated neurocognitive impairment (HNCI). The primary goal of this study is to evaluate the effectiveness of CNS-targeted (CNS-T) as compared to non-CNS-targeted (non-CNS-T) HAART in treating HNCI globally and in different domains of functioning known to be affected by HIV. It is hypothesized that participants in the CNS-T arm will have greater improvement in neurocognitive functioning than those in the non-CNS-T arm. The secondary goal of the study is to compare participants assigned to CNS-T and non-CNS-T HAART on measures of CNS and systemic HIV suppression (undetectable CSF and plasma VL). It is also hypothesized that although CSF viral suppression will be more frequent in the CNS-T arm, plasma viral suppression will be similar in the two treatment arms.
