Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Area Under the Curve From Time 0 to Infinity (AUC0-inf) of Plasma Islatravir (ISL)	Participants were treated with islatravir (ISL), and blood samples were collected from pre-dose up to 168 hours post-dose to determine the concentration of plasma ISL. The 95% confidence interval was derived from a fixed effects model performed on natural log-transformed values.	Pre-dose, 0.25, 0.5, 1, 2, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, 168 hours post-dose

Primary	Time of Maximum Concentration (Tmax) of Plasma ISL	Participants were treated with ISL, and blood samples were collected from pre-dose up to 168 hours post-dose to determine the concentration of plasma ISL.

Secondary	Percentage of Participants With an Adverse Event (AE)	An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.

Up to Day 29
Secondary	Percentage of Participants Who Discontinued From the Study Due to an AE	An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
