  Purpose

The purpose of this study is to evaluate the effect that telaprevir has on the pharmacokinetics of cyclosporine and tacrolimus. Pharmacokinetics means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body.

Primary Outcome Measures:
  • Part A only: Pharmacokinetic parameters of cyclosporine (Cmax, AUC0-tlast, AUC0-inf, tmax, t1/2) [ Time Frame: 33 days ] [ Designated as safety issue: No ]
  • Part A and Part B: Pharmacokinetic parameters of telaprevir (Cmax, AUC0-8h, Cmin, tmax) [ Time Frame: 33 days for Part A; 44 days for Part B ] [ Designated as safety issue: No ]
  • Part B only: Pharmacokinetic parameters of tacrolimus (Cmax, AUC0-tlast, AUC0-inf, tmax, t1/2) [ Time Frame: 44 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Part A and Part B: Safety and tolerability as measured by adverse events, clinical laboratory assessments, electrocardiograms, vital signs, physical examinations [ Time Frame: 33 days for Part A; 44 days for Part B ] [ Designated as safety issue: Yes ]

Criteria

Inclusion Criteria:

  • Healthy female (non-childbearing potential) or male subjects between 18 and 60 years of age (inclusive)
  • Body mass index (BMI) from 18 to 30 kg/m2 (inclusive) at the Screening Visit and Day 1, and weigh more than 50 kg at Screening.
