TMC114-TiDP3-C176 - A Study in Healthy Volunteers Investigating the Bioequivalence Between Two Commercially Available 400-mg Tablets to One New 800-mg Tablet of Darunavir (DRV) in the Presence of Low-dose Ritonavir Under Fed and Fasted Conditions

February 5, 2014 updated by: Tibotec Pharmaceuticals, Ireland

A Phase I, Open-label, Randomized, 2-panel, 2-way Crossover Pivotal Bioequivalence Trial Between the Commercially Available 400-mg Tablet Formulation (F030) and the 800-mg Tablet Formulation of Darunavir (G002), in the Presence of Low-dose Ritonavir Under Fasted and Fed Conditions

In this study participants will be given 800 mg darunavir, either as one 800-mg tablet formulation (G002), or as two commercially available 400-mg tablets formulation (F030), to evaluate the effect between both, in the presence of low-dose ritonavir under fasted and fed conditions.

Detailed Description

Darunavir (DRV, formerly known as TMC114) is an inhibitor of human immunodeficiency virus (HIV) protease. This study is designed to establish the bioequivalence of a commercially available 400-mg tablet formulation (F030) to one 800-mg tablet formulation of DRV (G002) in the presence of low-dose ritonavir under fasted and fed conditions. This is a Phase I, open-label (both participant and investigator know the name of the medication given at certain moment), randomized (study medication is assigned by chance), 2-panel, 2-way crossover study in healthy volunteers to assess the bioequivalence of DRV following administration of 2 tablet strengths (in the presence of low-dose ritonavir) under fasted and fed conditions. A total of 124 participants will participate in this study. Participants will be divided into 2 panels; 80 participants in Panel 1 (fasted) and 44 in Panel 2 (fed). In Panel 1, during 2 subsequent sessions, each participant will receive 2 treatments under fasted conditions, meaning Treatment A, a single oral 800-mg dose of DRV formulated as the 400-mg commercially available tablet F030 and Treatment B, a single oral 800-mg dose of DRV formulated as the 800-mg tablet formulation G002. In Panel 2, the same design as Panel 1 will be followed but under fed conditions, and where the 2 treatments, respectively, will be called Treatments C and D. In both panels, participants will receive ritonavir 100 mg once a day on Days 1 to 5. Ritonavir will be administered under fed conditions in both panels except for the morning intake on Day 3 in Panel 2 where it will be administered under fasting conditions. A washout period of at least 7 days between subsequent treatments will be observed. Safety (blood and urine tests, blood pressure, pulse, electrocardiogram, and physical examination) and tolerability evaluations will be recorded at regular intervals throughout the trial. Panel 1 (fasted condition) and Panel 2 (fed condition): a single dose of 800 mg DRV on Day 3 and 100 mg ritonavir once daily from Day 1 to 5. DRV will be formulated as the commercially available 400-mg tablet formulation (F030) or as the investigational 800-mg tablet formulation (G002). Ritonavir will be used as the commercially available melt-extrusion tablet containing ritonavir eq. 100 mg.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

Yes
