TMC114-TiDP3-C181: Study to Assess the Pharmacokinetics of Darunavir (DRV) With Different Doses of Ritonavir in Healthy Volunteers.

June 8, 2011 updated by: Tibotec Pharmaceuticals, Ireland

Phase I, Open-label, Randomized, 3-way Crossover Trial to Assess the Pharmacokinetics of Darunavir (DRV) Given Once-daily With Different Doses of Ritonavir in Healthy Subjects.

The objectives are to determine the effect of different ritonavir doses on darunavir (DRV) oral exposure following once-daily oral dosing of DRV/rtv for 7 days, in order to establish an optimal ritonavir boosting dose for DRV and to evaluate short-term safety and tolerability.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a Phase I, open-label, randomized (study drug assigned by chance), 3-way crossover trial in healthy volunteers to assess the pharmacokinetics of darunavir (DRV), co-administered with different doses of ritonavir. The trial population will consist of 18 healthy adult volunteers. During 3 subsequent sessions, each volunteer will receive in a randomized way: Treatments A, B and C. In Treatment A, 800 mg DRV once-daily and 100 mg ritonavir once-daily will be administered. In Treatment B, 800 mg DRV once-daily and 50 mg ritonavir once-daily will be administered. In Treatment C, 800 mg DRV once-daily and 20 mg ritonavir once-daily will be administered. All treatments will be administered for 7 days and intake of DRV and ritonavir will be under fed conditions. DRV will be formulated as a 400 mg tablet; ritonavir will be formulated as an oral solution containing 80mg/mL ritonavir. In each treatment session, full pharmacokinetic profiles of DRV and ritonavir will be determined up to 24 hours after administration on Day 1 and up to 72 hours after administration on Day 7. There will be a washout period of at least 7 days between subsequent treatments. Safety and tolerability will be evaluated continuously throughout the trial. During 3 subsequent sessions, each volunteer will receive in a randomized way Treatments A, B and C. In Treatment A, 800/100 mg DRV/rtv once-daily will be administered. In Treatment B, 800/50 mg DRV/rtv once-daily will be administered. In Treatment C, 800/20 mg DRV/rtv once-daily will be administered. All treatments will be administered for 7 days. DRV will be formulated as a 400 mg tablet; ritonavir will be formulated as an oral solution containing 80mg/mL ritonavir.

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

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Healthy on the basis of a medical evaluation that reveals the absence of any clinically relevant abnormality and includes a physical examination, medical history, electrocardiogram (ECG), vital signs, and the results of blood biochemistry, blood coagulation and hematology tests and a urinalysis carried out at screening

Exclusion Criteria:

  • A positive HIV-1 or HIV-2 test at screening
  • Hepatitis A, B, or C infection (confirmed by hepatitis A antibody IgM, hepatitis B surface antigen [with a positive hep B PCR], or hepatitis C virus antibody, respectively) at Screening
  • Any history of significant skin disease such as, but not limited to, rash or eruptions, food or drug allergy, dermatitis, eczema, psoriasis, folliculitis, or urticaria
  • Use of concomitant medication, including over-the-counter products, herbal preparations and dietary supplements. Concomitant medication must have been discontinued at least 14 days before the first dose of trial medication except for paracetamol (acetaminophen), hormone replacement therapy and hormonal contraceptives
  • Participation in an investigational drug trial within 60 days prior to the first intake of trial medication.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
To determine the effect of different ritonavir doses (20, 50, 100 mg ritonavir) in DRV oral exposure following once-daily oral dosing of DRV/rtv for 7 days, in order to establish an optimal ritonavir boosting dose for DRV

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
To evaluate short-term safety and tolerability of DRV following administration of DRV 800 mg once-daily in the presence of different doses of ritonavir for 7 days in healthy volunteers

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
