About this study

Official title: A Phase I, Open-label, Sequential Trial to Investigate the Pharmacokinetics, Safety, and Tolerability of TMC435 in Subjects With Moderately or Severely Impaired Hepatic Function

The purpose of the study is to investigate the effect of moderate and severe hepatic impairment on the pharmacokinetics of TMC435. Pharmacokinetics means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body. In addition, the short-term safety and tolerability of TMC435 in participants with hepatic impairment will be determined. The results of this study will guide dose recommendations for TMC435 in patients with impaired liver function.

Read the detailed description

This is a Phase I, open-label trial to investigate the pharmacokinetics (how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body) of TMC435 in 8 participants with moderate hepatic impairment and 8 participants with severe hepatic impairment as compared to 8 participants with normal hepatic function, matched for age, gender, race, BMI (body mass index = weight in kilogram divided by square of height in meters) and smoking status. Open-label means that the study doctor and the participants know what treatment will be assigned to them. All participants will receive 150 mg of TMC435 by mouth for 7 days. Participants with severe hepatic impairment will be treated when the pharmacokinetic profiles of TMC435 in participants with moderate hepatic impairment have been evaluated. The dose of TMC435 may be changed for participants with severe hepatic impairment after evaluation of the blood levels TMC435 in participants with moderately impaired hepatic function. Tolerability and safety of TMC435 will be assessed throughout the trial period. Illnesses and side effects will be checked at every visit. Blood samples will be taken at screening, on the day before TMC435 intake, on days 2, 3, 5, 6, 7 (11 times), 8 and 9 and at 2 follow-up visits. Blood levels of TMC435 will be determined on days 2, 5, 6, 7, 8 and 9. Urine samples, ECG and vital signs will be taken at screening, twice on day 7 and at 2 follow-up visits. A physical examination will be done at screening, on the day before TMC435 intake, on day 9 and at both follow-up visits. All participants will receive a 150 mg dose of TMC435 for 7 days, given by mouth as 2 capsules of 75 mg. After evaluation of the pharmacokinetic profiles of TMC435 in participants with moderate hepatic impairment, the dose may be changed for participants with severe hepatic impairment.

Panel A: TMC435 150 mgExperimentalParticipants enrolled in Panel A had moderate hepatic failure and received TMC435 150 mg once daily for 7 days.
Receives: Drug: TMC435
Panel B: TMC435 150 mgExperimentalParticipants enrolled in Panel B had severe hepatic impairment and received TMC435 150 mg once daily for 7 days after the safety of TMC435 150 mg once daily for 7 days was evaluated in participants enrolled in Panel A.

What is being measured

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

  1. Pharmacokinetic profile of TMC435 in patients with moderate and severe hepatic impairment

    Measured: Measured at 16 predefined time points over a period of 9 days. Extensive analysis is planned on Day7 (after last intake of TMC435), with 12 PK sampling moments over 48 hours.

Secondary outcomes (1)
  1. Short-term safety and tolerability of TMC435 in volunteers with moderate or severe hepatic impairment

    Measured: AEs monitored each visit; vital signs, urinalysis and ECG parameters on Day 7 and on both follow-up visits; Safety blood sample at 6 predefined timepoints (over 5 days) and on both follow-up visits.

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 at 3 sites in United States.

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 2 inclusion and 2 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 14 Oct 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Pharmacokinetic profile of TMC435 in patients with moderate and severe hepatic impairment (time frame: Measured at 16 predefined time points over a period of 9 days. Extensive analysis is planned on Day7 (after last intake of TMC435), with 12 PK sampling moments over 48 hours.). 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 14 Oct 2013.
