VX-950-TiDP24-C132: A Study to Investigate the Effect of Renal Impairment on the Pharmacokinetics of Telaprevir.

December 16, 2010 updated by: Tibotec BVBA

A Phase I Open-label Trial to Investigate the Effect of Severe Renal Impairment on the Single-dose Pharmacokinetics of Telaprevir.

The purpose of this study is to investigate the effect of severe renal impairment or failure on the single-dose pharmacokinetics of telaprevir (TVR). Pharmacokinetics means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body. In addition, the effect of severe renal impairment on the total and unbound plasma concentrations of the sum of TVR and its R-diastereomer VRT-127394 will be assessed. (Diastereomers are substances whose chemical structures are mirror images of each other). Finally, the short-term safety and tolerability of TVR in participants with severe kidney disease will be determined. The results of this study will guide dose recommendations for TVR in subjects with kidney disease.

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 trial to investigate the single-dose pharmacokinetics of telaprevir (TVR) in 12 participants with severe renal impairment (defined as creatinine clearance (CrCl) < 30 mL/min) as compared to 12 participants with normal renal function, matched for sex, race, age (± 10 years) and BMI (± 20%). Open-label means that the study doctor and the participants know what treatment will be assigned to them. All participants will receive a single 750-mg dose of TVR. Pharmacokinetic profiles of total TVR up to 24 hours postdose will be determined. A 24 hour urine collection test will be performed to estimate the CrCl. In addition, the effect of severe renal impairment on the total and unbound plasma concentrations of the sum of TVR and VRT-127394 will be assessed. Tolerability and safety of TVR will be assessed throughout the trial period. Illnesses and side effects will be checked at every visit. Blood and urine samples will be taken at screening, on Day 1, 2 and at the 2 follow-up visits. ECG and vital signs will be taken at screening, twice on day 1, on day 2 and at the first follow-up visit. At the second follow-up visit vital signs alone will be determined. A physical examination will be done at screening, on the day before TVR intake, on day 2 and at both follow-up visits. All participants will receive a single 750-mg dose of telaprevir (TVR) given by mouth as 2 tablets of 375 mg.

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

14 years to 66 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Males are allowed and females of childbearing potential if adequate contraception is used. Females of non-childbearing potential should be amenorrheal for at least 2 years, or have undergone tubal ligation (or other permanent birth control methods), or hysterectomy (total), or oophorectomy (bilateral)
  • For participants with severe renal impairment: consistent with the disease process of chronic renal failure and associated symptoms, otherwise judged to be in good health in the opinion of the investigator on the basis of a medical evaluation (including a physical examination, medical history, electrocardiogram (ECG), vital signs, and screening laboratory tests), with any concomitant medical conditions under stable medical control
  • For participants with severe renal impairment: creatinine clearance < 30 mL/min (Cockcroft-Gault)
  • For healthy controls: healthy on the basis of a medical evaluation that reveals the absence of any clinically relevant abnormality and includes a physical examination, medical history, ECG, vital signs, and the results of blood biochemistry, blood coagulation and hematology tests and a urinalysis carried out at screening

Exclusion Criteria:

  • A history of any illness (unrelated to renal impairment, as appropriate) that, in the opinion of the investigator, might confound the results of the study or pose an additional risk in administering study medication to the participant. This may include but is not limited to: diabetes mellitus, history of relevant drug or food allergies
  • history of cardiovascular or central nervous system disease
  • history or presence of clinically significant pathology, chronic skin disease, or history of mental disease
  • For subjects with severe renal impairment: history of renal transplant or renal carcinoma. Participants with a history of renal carcinoma who have been cancer free for at least 5 years may be included
  • For participants with severe renal impairment: participants with End Stage Renal Disease (ESRD) requiring dialysis
  • For healthy controls: current use of prescription medication and regular treatment with over-the-counter medications

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
Time Frame
The primary objective of this study is to investigate the effect of severe renal impairment on the single-dose pharmacokinetics of total telaprevir. Total telaprevir is the sum of telaprevir bound to plasma proteins and unbound (free) telaprevir.
Time Frame: Pharmacokinetic profiles of total TVR up to 24 hours postdose will be determined. Twenty-four hour urine will be collected for estimation of CrCl.
Pharmacokinetic profiles of total TVR up to 24 hours postdose will be determined. Twenty-four hour urine will be collected for estimation of CrCl.

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
Time Frame
The effect of severe renal impairment on total and unbound plasma concentrations of the sum of TVR and VRT-127394 will be investigated.
