About this study
Official title: Phase I, Open-label Trial to Investigate the Effect of Severe Renal Impairment on the Pharmacokinetics and Safety of TMC435
The purpose of this study is to assess the steady-state pharmacokinetics of TMC435 in participants with severe renal impairment and to compare these with the TMC435 pharmacokinetics in matched participants with normal renal function. We will also study the short-term safety and tolerability of TMC435, when administered in participants with severe renal impairment and in participants with normal renal function. 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. TMC435 is being investigated for the treatment of chronic hepatitis C virus (HCV) infection. 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). The result of this study may provide dosing recommendations for TMC435 in patients with severe renal impairement. This is a Phase I, open-label (both participant and investigator know the name of the medication given at certain moment), to investigate the effect of severe renal impairment on the pharmacokinetics and safety of TMC435. Severe renal impairment will be defined by an estimated glomerular filtration rate (eGFR) = 29 mL/min/1.73m2. Participants with severe renal impairment are only allowed in this study if they are not on dialysis. Normal renal function will be considered as an eGFR = 80 mL/min/1.73m2. eGFR is a measured filtering capacity of the kidneys. The trial population will consist of a total of 16 male or female participants. Eight (8) healthy participants with a normal renal function and 8 participants with severe renal impairment will be included. A healthy participant will be matched to a participant with severe renal impairment with regards to sex, race, age (± 10 years), and body mass index (BMI) (± 20%). Dosing of the matched healthy participants can only start once the corresponding participants with severe renal impairment has completed Day 10 assessments (including physical examination). All participants will receive TMC435150 mg once a day (q.d.) for 7 days under fed conditions. Blood and urine samples, electrocardiogram (ECG) and vital signs (blood pressure and heart rate) will be taken at screening, on Day 1, Day 7, at the follow-up visit at 1 week after last dose of study medication and at the follow-up visit at 4-5 weeks after last dose of study medication. A physical examination will be performed at screening, on Day -1 (= day before first medication intake), on Day 10 and during the follow-up visits. A full pharmacokinetic profiles of bound TMC435 will be determined on Day 7 up to 72 hours postdose. In addition, unbound TMC435 plasma concentrations will be determined at specified timepoints. Safety and tolerability will be monitored throughout the trial. Participants will be admitted to the unit on Day-1 and discharged on Day10. Each participant will receive orally 150 mg TMC435, q.d. for 7 consecutive days.

Where is the study taking place?
The record lists 1 site in Czechia. 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 pharmacokinetics of TMC435 following administration in participants with severe renal impairement, as compared to the matching healthy participants. (time frame: Measured on Day 5-10.). 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.
