Brief Summary
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.

Outcome Measures
Primary Outcomes (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 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)
Number of participants with adverse events as a measure of safety and tolerability when combining TMC435 (150 mg, q.d.) with cyclosporine or tacrolimus.
Up to Day 50.
Study Arms (4)
001
EXPERIMENTALa single 100-mg dose of cyclosporine, and after a wash out period of at least 10 days, TMC435 150 mg once daily (q.d.) for 10 days on Days 1 to 10, coadministered with a single 100-mg dose of cyclosporine on Day 7.
002
EXPERIMENTALTMC435 150 mg once daily (q.d.) for 10 days on Days 1 to 10, coadministered with a single 100-mg dose of cyclosporine on Day 7 and after a wash out period of at least 10 days, a single 100-mg dose of cyclosporine.
003
EXPERIMENTALa single 2-mg dose of tacrolimus on Day 1. After a wash out period of at least 10 days, participants will receive TMC435 150 mg q.d. for 12 days on Days 1 to 12, coadministered with a single 2-mg dose of tacrolimus on Day 7.
004
EXPERIMENTALTMC435 150 mg q.d. for 12 days on Days 1 to 12, coadministered with a single 2-mg dose of tacrolimus on Day 7. After a wash out period of at least 10 days, participants receive a single 2-mg dose of tacrolimus.
Interventions
a single 2-mg dose of tacrolimus (on Day 1 in treatment C and on Day 7 in treatment D).
A single 100-mg dose of cyclosporine (on Day 1 of treatment A and on Day 7 of treatment B).
