A Study to Assess the Long-term Safety and Tolerability of TMC114/Rtv in HIV-1 Infected Participants After Rolling-over From Other TMC114 Trials

August 22, 2014 updated by: Tibotec Pharmaceuticals, Ireland

An Open Label Trial of TMC114/Rtv in HIV-1 Infected Subjects Who Were Randomized in the Trials TMC114-C201, TMC114-C207 or in Sponsor Selected Phase I Trials

The purpose of this study was primarily to assess the long-term safety and tolerability of TMC114/rtv in addition to an individually optimized background antiretroviral therapy in HIV-1 infected participants. In addition, antiviral activity and immunological effect were also evaluated.

Detailed Description

This was a phase II, open label, multicenter trial of an investigational protease inhibitor TMC114 in the presence of ritonavir (rtv) in HIV-1 infected participants who were randomized in trials TMC114-C201, TMC114-C207 or in sponsor selected phase I trials and who might derive benefit from TMC114 therapy, as judged by the investigator.

The trial consisted of a screening period of a maximum of 4 weeks, a 96-week treatment period and a 4-week follow-up period. The maximal trial duration for each participant was104 weeks. During the treatment period, all participants were receiving TMC114 in combination with RTV, orally, as 600/100 mg dose twice daily, in addition to an individually optimized background regimen of antiretroviral (ARV) therapy, selected by the investigator at a baseline of the study.

Sponsor provided a follow-up treatment with TMC114 for all participants who continued to benefit from treatment with TMC114/RTV until it became commercially available for the participant. Participants, who completed the 96 weeks of treatment period with TMC114, had the opportunity to roll over to the extension of this trial, if TMC114 was not locally commercially available.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
Number of participants with adverse events as a measure of safety and tolerability of TMC114/RTV 600/100 mg combination
Time Frame: Baseline, up to the end of follow-up period (approximatelly 100 weeks)
Baseline, up to the end of follow-up period (approximatelly 100 weeks)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of patients with HIV-1 plasma viral load level <50 copies/mL (TLOVR, non-VF censored)
Time Frame: Week 48, Week 96
The Time to Loss of Virologic Response (TLOVR) algorithm will be used to derive response. Response will be confirmed at 2 consecutive visits and participants who discontinue will be considered nonresponders after discontinuation. Resuppression after confirmed virologic failure will be considered as failure. Virologic Failure will include participants who are rebounders (ie, confirmed viral load >= 50 copies/mL after being a responder) or who were never suppressed (no confirmed viral load <50 copies/mL); non-VF censored: participants who discontinue treatment due to reason other than Virologic Failure will be excluded.
Week 48, Week 96
Change in CD4 cells absolute count
Time Frame: Week 48, Week 96
The immunologic change will be determined by changes in absolute values for CD4 cells.
Week 48, Week 96
