A Study of TMC278 in Human Immunodeficiency Virus Type 1 Infected Patients, Who Are Not Treated With Antiretroviral Medicines

11 juni 2014 bijgewerkt door: Tibotec Pharmaceuticals, Ireland

A Phase IIb Randomized, Partially Blinded, Dose-Finding Trial of TMC278 in Antiretroviral-Naive HIV-1 Infected Subjects

The purpose of this study is to evaluate the dose-response relationship of antiviral activity after 48 weeks treatment with 3 different dose regimens of TMC278.

Studie Overzicht

Gedetailleerde beschrijving

This is a randomized (the study medication is assigned by chance), active controlled (participants are assigned to either a recognized effective treatment or the study medication) study. This study consists of 3 phases: screening phase (4 weeks), treatment phase (96 weeks), and follow up phase (4 weeks). In the treatment phase, participants will be randomly assigned to 1 of the 4 treatment groups: (1) TMC278 25 mg, (2) TMC278 75 mg, (3) TMC278 150 mg, or (4) efavirnez (control group); along with investigator selected 2 non-nucleoside reverse transcriptase inhibitor (NRTIs) until Week 96. TMC278 will be assigned by double-blinded fashion (participant and investigator are not aware of the TMC278 dose what participants will receive) and efavirnez will be assigned by open-label fashion (all people know what treatment participants will receive). After Week 96, 3 optional open-label (all people know the identity of the intervention) extension periods will be conducted to collect long term safety and effectiveness data of TMC278. 3 optional extension periods are: first optional extension period (all participants will receive TMC278 75 mg + 2 NRTIs from Week 96 to Week144); second optional extension period (all participants will receive TMC278 25 mg + 2 NRTIs from Week 144 to Week 240); and third optional extension period (all participants will receive TMC278 25 mg + 2 NRTIs from Week 240 until TMC278 is commercially available). Participants on efavirenz group will have the option to continue on efavirenz + 2 NRTIs until the total treatment duration of 240 weeks. Safety evaluations will include assessment of adverse events, clinical laboratory tests, electrocardiogram, physical examination, and vital signs which will be monitored throughout the study. The maximum duration of the study will be 104, 152, or 248 weeks, plus the optional third extension period.

Tijdsspanne
Number of Participants With Virologic Response at Week 48 (Viral Load Less Than 50 Copies Per mL) - as Defined by the Time to Loss of Virologic Response (TLOVR) Algorithm
Tijdsspanne: Week 48
The TLOVR algorithm was used to derive response, ie, response and loss of response needed to be confirmed at 2 consecutive visits and participants who permanently discontinued were considered nonresponders. Participants with intermittent missing viral load values were considered responders if the preceeding and succeeding visits indicated response. In all other cases, intermittent values were imputed with nonresponse. Resuppression after confirmed virologic failure was considered as failure in this algorithm.

Virologic failure for the resistance determinations was defined as a viral load greater than 0.5 log10 copies /mL above the nadir with a minimum of 500 copies/mL. For this study, treatment-emergent mutations (for at least one treatment) are presented as Resistance associated mutation (RAMs): i) Non-nucleotide reverse transcriptase inhibitor (NNRTI) RAMs, ii) Nucleoside/tide reverse transcriptase inhibitor (N[t]RTI RAMs).

Area Under the Plasma Concentration Time Curve From Time 0 to 24 Hours (AUC24h) for TMC278
Tijdsspanne: Up to Week 96
For each participant, a single value for area under the plasma concentration-time curve from time of administration up to 24 hours post dosing (AUC24h) of TMC278 was estimated from a population pharmacokinetic model, based on all samples collected throughout the trial up to Week 96.
Up to Week 96
Trough Plasma Concentration (Ctrough) for TMC278
Tijdsspanne: Up to Week 96
For each participant, a single value for trough (i.e. predose) plasma concentration (Ctrough) of TMC278 was estimated from a population pharmacokinetic model, based on samples collected throughout the trial up to Week 96.

Tijdsspanne: Up to Week 96
Quartile 1, 2, 3 and 4 of AUC24h means the quartile with the lowest 25%, 26-50%, 51-75% and the highest 25% of AUC24h values, respectively, irrespective of the different doses of TMC278. For each participant, a single value for area under the plasma concentration-time curve from time of administration up to 24 hours post dosing (AUC24h) of TMC278 was estimated from a population pharmacokinetic model, based on all samples collected throughout the trial up to Week 96. Virologic response was calculated by time to loss of virologic response (TLOVR) algorithm.
