About this study

Official title: A Phase I, 2-panel, Open-label, Randomized, Cross-over Trial in Healthy Subjects to Investigate the Effect of TMC435 at Steady-state on the Pharmacokinetics of the Immunosuppressants Cyclosporine and Tacrolimus

The purpose of this study is to investigate the effect of steady-state concentrations of TMC435 (administered once a day) on the single-dose pharmacokinetics of the immunosuppressants cyclosporine and tacrolimus in healthy participants. Cyclosporine and tacrolimus are immunosuppressants used to prevent transplant rejection and may therefore potentially be coadministered with TMC435 in patients infected with hepatitis C virus that undergo liver transplantation. We will also explore the short-term safety and tolerability following coadministration of TMC435 at steady-state and (1) cyclosporine or (2) tacrolimus after single dosing in healthy participants. Steady-state is a term that means that the drug has been given long enough so that the plasma concentrations will remain the same with each subsequent dose. Pharmacokinetics (PK) means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body.

Read the detailed description

TMC435 is a protease inhibitor (PI) and is being investigated for treatment of chronic hepatitis C virus (HCV) infection, in combination with Peg-IFN (pegylated interferon) and RBV (ribavirin). This is a Phase I, open-label (both participant and investigator know the name of the medication given at a certain moment) trial in 28 healthy participants to investigate the effect of TMC435 at steady-state on the single dose pharmacokinetics of the immunosuppressants cyclosporine and tacrolimus. The trial population will consist of a total of 28 healthy participants, equally divided over 2 panels. In Panel 1, each participant will receive 2 treatments: a single 100-mg dose of cyclosporine on Day 1 and TMC435 150 mg once daily for 10 days on Days 1 to 10, coadministered with a single 100-mg dose of cyclosporine on Day 7. In Panel 2, each participant will receive 2 treatments: a single 2-mg dose of tacrolimus on Day 1 and TMC435 150 mg each day for 12 days on Days 1 to 12, coadministered with a single 2-mg dose of tacrolimus on Day 7. Safety and tolerability will be assessed during the study period and during follow up. Blood and urine safety samples, electrocardiogram (ECG) and vital signs (blood pressure and heart rate) will be taken at screening, Day1, Day 2 (only panel 1), Day 7(only panel 2), Day 8 (only panel 2) and at the follow-up visit about 5 to 7 days after last TMC435 intake.

What is being measured

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

  1. Change in the steady-state plasma concentration (PK) of cyclosporine and tacrolimus following co-administration with TMC435.

    Change in the steady-state plasma PK of cyclosporine and tacrolimus following co-administration with TMC435. PK characteristics of cyclosporine and tacrolimus are determined based on their respective plasma levels at one time point (Day 1 and Day 7 for respectively panel 1 and panel 2) and at 17 other time points. Standard PK parameters such as C0h, Cmin, Cmax, Tmax, AUC24h etc. will be determined.

    Measured: Measured on Day1 till and including Day 7 for panel 1, and till and including Day 13 for panel 2. Reference is Day 1 for panel 1 and Day 7 for panel 2.

Secondary outcomes (1)
  1. Number of participants with adverse events as a measure of safety and tolerability when combining TMC435 (150 mg, q.d.) with cyclosporine or tacrolimus.

    to explore the short-term safety and tolerability following coadministration of TMC435 at steady-state and (1) 100-mg dose cyclosporine or (2) 2-mg dose tacrolimus after single dosing in healthy subjects.

    Measured: Up to Day 50.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing tacrolimus, TMC435 and cyclosporine in people with Hepatitis C Virus, run by Tibotec Pharmaceuticals, Ireland at 1 site in Belgium.

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 1 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 1 Nov 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. 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?

Change in the steady-state plasma concentration (PK) of cyclosporine and tacrolimus following co-administration with TMC435. (time frame: Measured on Day1 till and including Day 7 for panel 1, and till and including Day 13 for panel 2. Reference is Day 1 for panel 1 and Day 7 for panel 2.). 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 1 Nov 2012.
