  • Kaletra

Detailed Description:

This will be an open-label, 3-period, fixed sequence study in young, healthy, male and female subjects. The initial cohort, to be studied simultaneously, will be 15 subjects with intention to collect complete data from 12 subjects. Replacements will be subsequently enrolled if necessary. Subjects will be reimbursed.

The periods will be

  • Period 1: Raltegravir (RAL) 400 mg q12h for 4 days (7 doses of RAL).
  • Period 2: Kaletra 200 mg 2 pills bid for 10 days (19 doses of Kaletra).
  • Period 3: both regimens for 4 days (7 doses of both drugs). All morning doses will be observed at Prism Research, Inc. Evening doses will be distributed each morning. 12 hour PK studies will be done on the last day of each period. Specimens will be obtained 0, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12 hours after the morning dose of the last dosing day of each period.
