About this study

Official title: A Phase I Study in Healthy Subjects to Assess the Relative Bioavailability of TMC435 Following Administration of Potential Phase III Formulations Compared to the Phase IIb Capsule and to Assess the Effect of Food on the Bioavailability of TMC435 Following Intake of the Phase IIb Capsule

The purpose of this study is to compare the levels of TMC435 in the blood circulation after intake of 2 tablet formulations with the level of TMC435 in the blood circulation after intake of a capsule formulation. The trial will also evaluate levels of TMC435 in the blood circulation after intake of the capsule formulation fasted or following a meal.

Read the detailed description

This is a randomized (study drug assigned by chance), open-label (all people involved know the identity of the intervention), single dose, crossover (volunteers will receive different interventions sequentially during the trial) study in healthy volunteers. The trial will evaluate the levels of TMC435 in the blood circulation after a single dose of 150 mg TMC435 as a capsule formulation taken fasted (Treatment A) and following a meal (Treatment B). In addition, the study will evaluate the levels of TMC435 in the blood circulation after intake of a single dose of 150 mg TMC435 as 2 different tablet formulations (Treatments C and D). There will be a 14-day washout period between treatments and a 4-5 week follow-up at the end. Each volunteer will receive all four treatments. The main focus of the trial is the pharmacokinetic characteristics (how drugs are absorbed in the body, how they are distributed within the body and how they are removed from the body over time) of the different formulations. This evaluation requires multiple blood samples from Day 1 through 72 hours after dosing. Safety assessments (lab work, blood pressure, pulse and electrocardiogram) will follow a different schedule and are measured on Day -1 (day prior to taking first dose of drug), Day 1 (day of first dosing) and/or Day 4 of each treatment period, and 4 weeks after the last treatment. Each volunteer will receive 4 treatments, about 14 days apart from each other. Each treatment consists of one single dose of 150 mg TMC435.

  • TMC435Drug

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate and extent of absorption of TMC435 following administration of the tablet vs the capsule formulations and rate and extent of absorption of TMC435 following administration of the capsule formulation fasted or with food

    Measured: Measured over a period of 4 consecutive days (Day1-Day4) per treatment. Treatments (4) are 14 days apart from each other. During 1st day of each treatment, 10 blood samples for determination of pharmacokinetic characteristics are taken.

Secondary outcomes (1)
  1. Safety and tolerability following administration of single doses of 150 mg TMC435

    Measured: AEs: continuously: laboratory, vital signs and ECG parameters: 3 visits per treatment, for 4 treatment periods

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TMC435 in people with Hepatitis C Virus, run by Tibotec Pharmaceuticals, Ireland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 May 2010. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate and extent of absorption of TMC435 following administration of the tablet vs the capsule formulations and rate and extent of absorption of TMC435 following administration of the capsule formulation fasted or with food (time frame: Measured over a period of 4 consecutive days (Day1-Day4) per treatment. Treatments (4) are 14 days apart from each other. During 1st day of each treatment, 10 blood samples for determination of pharmacokinetic characteristics are taken.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 May 2010.
