A Study With TMC125 in Human Immunodeficiency Virus (HIV) Type 1 Infected Patients, Who Were Treated With TMC125 Arm in a Sponsor-Selected TMC125 Study

An Open-Label Trial With TMC125 in HIV-1 Infected Subjects, Who Were Randomized to a TMC125 Treatment Arm in a Sponsor-Selected TMC125 Trial and Were Treated for at Least 48 Weeks

The purpose of this study is to evaluate the long-term safety and tolerability of etravirine, administered as part of an individually optimized antiretroviral therapy (ART), in human immunodeficiency virus Type 1 (HIV-1) infected participants.

This is a Phase II, open-label (all people know the identity of the intervention), roll-over study (participants may go ahead and participate in another clinical study). Participants who were randomized (study medication is assigned by chance) to a etravirine (ETR) treatment arm in Phase II TMC125 feeder studies (TMC125-C203, TMC125-C209, TMC125-C223 and TMC125-C211), were treated for at least 48 weeks with etravirine, and who will derive continued benefit from etravirine therapy, as judged by the investigator, will be enrolled in this study. The final visit of the sponsor-selected Phase II ETR study will be the first (baseline) visit of this study. Approximately 300 participants will be enrolled in this study who will receive 800 mg twice daily of etravirine (formulation TF035) until the formulation 200 mg twice daily (formulation F060) is available. Once this formulation becomes available all the participants will be switched to receive F060 which will be given in combination with an investigator-selected, optimized underlying therapy (nucleotide reverse transcriptase [NRTIs] and/or allowed protease inhibitors and/or enfuvirtide). Participants will continue to receive ETR until they are no longer benefitted or this medication becomes commercially available. Safety evaluations will include assessment of adverse events, clinical laboratory tests, electrocardiogram, vital signs, and physical examination.

Inclusion Criteria:

• Participants who were previously randomized to an etravirine (ETR) treatment arm and have completed at least 48 weeks of treatment with ETR
• Participants who will be able to comply with the protocol requirements
• Participants general medical condition should not interfere with the assessments and the completion of the study

Exclusion Criteria:

• Use of disallowed concomitant therapy unless a prior exemption had been granted
• Participant with any treatment-emergent condition or exacerbation of underlying condition during original Phase II study
• Agrees to protocol-defined use of effective contraception
• Participant with a grade 3 elevation of amylase and/or lipase except for isolated grade 3 increases of amylase with lipase in normal range and no history of pancreatitis
• Participant with any grade 4 toxicity according to the Division of Acquired Immunodeficiency Syndrome (DAIDS) grading table; with the exception of grade 4 elevations of triglycerides or glucose asymptomatic or under non-fasting conditions; grade 4 elevation of glucose in participants with pre-existing diabetes
• Participants with clinical or laboratory evidence of significantly decreased hepatic function or decompensation, irrespective of liver enzyme levels (International Normalized Ratio [INR] more than 1.5 or albumin less than 30g/l or bilirubin more than 2.5 x upper limit of normal)
