VX-950-TiDP24-C124: A Phase I Trial to Investigate the Potential Pharmacokinetic Interactions Between Telaprevir and Darunavir/Ritonavir and Between Telaprevir and Fosamprenavir/Ritonavir at Steady-state.

• Status: Completed
• Trial end date: 2008-10-01
• Target enrollment: 0
• Participant gender: All

Summary

The primary objectives are to determine the effect of steady-state DRV/rtv 600/100 mg twice daily (b.i.d.) on the steady-state pharmacokinetics of telaprevir 750 mg every (q) 8h and 1125 mg q12h and vice versa;- to determine the effect at steady-state of fAPV/rtv 700/100 mg b.i.d. on the steady-state pharmacokinetics of telaprevir 750 mg q8h and 1125 mg q 12h and vice versa; to determine the steady-state pharmacokinetics of telaprevir 750 mg q8h versus telaprevir 1125 mg q12h, alone and during coadministration of either steady-state DRV/rtv 600/100 mg b.i.d or fAPV/rtv 700/100 mg b.i.d.

Exclusion Criteria:

• Subjects must not have a history of any illness that, in the opinion of the investigator or the subject's general practitioner, might confound the results of the study or pose an additional risk in administering trial drug(s) to the subject

Subjects should stop over-the-counter medications on the date of the screening visit but no less than 7 days prior to the first administration of study medication (Day 1 of Session I). Potential subjects should not stop any chronic, over-the-counter medication being taken at the direction of a physician, without obtaining agreement from that physician

• Subjects should not consumeherbal medications or dietary supplements and grapefruit or grapefruit juice, apple juice, or orange juice within 14 days before the first administration of study medication (Day 1 of Session I)

• Subjects should not have a history of drug or alcohol abuse or addiction within 2 years prior to dosing, or who test positive for alcohol or drugs such as amphetamine, barbiturates, benzodiazepines, cocaine, cannabinoids, opioids, metamphetamine and methadone during the screening period

• Subject should not have participated in a clinical study involving administration of an investigational drug within 3 months or 5 half lives (whichever is longer) prior to the screening visit.
