Official title
Steady State Pharmacokinetics (PK) of Fosamprenavir (FPV) Alone or in Combination With Low Dose Ritonavir (/r) (1400mg BID, 1400mg/100mg QD or 700/100mg BID) and the Chemokine Receptor 5 (CCR5) Entry Inhibitor Maraviroc (MVC) 300mg BID in Healthy Volunteers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
To date, no study has investigated whether there is a drug interaction between the protease inhibitor fosamprenavir and the entry inhibitor maraviroc. COL112237 is a randomized, open-label, 6-arm, 3-period, drug interaction study to assess steady-state plasma amprenavir (APV) and maraviroc (MVC) pharmacokinetics in 48 healthy, HIV-negative adults after administration of a 7-day regimen of MVC 300mg BID alone and after 14-day regimens of unboosted fosamprenavir (FPV) 1400mg twice daily (BID), FPV 700mg/RTV 100mg BID, or FPV 1400mg/ritonavir (RTV) 100mg once daily (QD) with and without concurrent MVC 300mg BID. Blood samples for drug concentration measurement will be collected over 12 hours at the end of each dosing period. Subjects will undergo a physical examination, complete blood count (CBC) with differential, HIV test, hepatitis B/C test, liver function test, renal function analysis, and lipid panel at screening, and all of these tests, except those for HIV and hepatitis B/C, will be repeated at follow-up post-study. Adverse events and adherence (by pill count and medication diary) will be assessed by the investigator/study personnel at the end of each dosing period.
