Stribild Arm
Stribild Arm is for participants taking Stribild at the time of study entry. Participants taking Stribild at the time of study entry will switch to Genvoya before the second PK. Stribild: To be administered orally, once daily with food. Genvoya: To be administered orally, once daily with food.
Genvoya Arm
Genvoya Arm is for participants already taking Genvoya at the time of study entry. Participants taking Genvoya at the time of study entry will continue Genvoya for the second PK. Genvoya: To be administered orally, once daily with food.
Untreated Arm
Untreated Arm is for participants who are not taking ART at the time of study entry. Participants will start Stribild at entry and switch to Genvoya before the second PK. Stribild: To be administered orally, once daily with food. Genvoya: To be administered orally, once daily with food.
