E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine concentration of Maraviroc in directly aspirated fluid and tissue from the genital tract and rectal compartments at different time periods following a single oral administration of Maraviroc 300mg in HIV-1-negative healthy volunteers
|
|
