T/PR + Immunosuppressant Regimen (Tacrolimus)

Participants who were receiving tacrolimus (TAC) based immunosuppressant regimen at baseline, received telaprevir (T) 1125 milligram (mg) tablet twice daily for 12 weeks in combination with pegylated interferon alfa 2a (P) (Peg-IFN-alfa-2a) 180 microgram per week (mcg/week) subcutaneous injection and ribavirin (R) (RBV) tablet orally twice daily at a dose of 1000 milligram per day (mg/day) for subjects weighing less than (\<) 75 kilogram (kg) and 1200 mg/day for subjects weighing greater than or equal to (\>=) 75 kg, for 48 weeks. Participants continued their immunosuppressant regimen, as per standard practice and investigator discretion.
