Detailed description

MTN-035 is a multi-site, randomized-sequence, three-period, open label crossover study that will enroll approximately 210 participants randomized (1:1:1:1:1:1) to one of six sequences of rectal microbicide placebo product application. At the start of each 4-week product use period, participants will receive either rectal inserts, rectal douches, or rectal suppositories and be instructed to use their assigned study product prior to each receptive anal intercourse (RAI) encounter during that period. Participants who do not have RAI in a given week will be asked to use the product without sex. There will be a 1-week washout period between each of the three product use periods. Participant follow-up will take approximately 3.5 months.

Interventions

Type	Name	Description
BEHAVIORAL	Placebo rectal insert	Participants will be instructed to insert in the rectum a placebo insert prior to RAI. If a dose is missed, participants will be instructed to wait to take a dose at the next occurrence of RAI. Furthermore, if no RAI activity occurs at all in a given 7-day period, participants will be instructed to take a dose on the seventh day in the absence of RAI.
BEHAVIORAL	Placebo rectal suppository	Participants will be instructed to insert in the rectum a placebo suppository prior to RAI. If a dose is missed, participants will be instructed to wait to take a dose at the next occurrence of RAI. Furthermore, if no RAI activity occurs at all in a given 7-day period, participants will be instructed to take a dose on the seventh day in the absence of RAI.
BEHAVIORAL	Placebo rectal douche	Participants will be instructed to insert in the rectum a placebo douche (enema bottle with approximately 120 mL of clean tap water or bottled water) prior to RAI. If a dose is missed, participants will be instructed to wait to take a dose at the next occurrence of RAI, or if no other RAI activity occurs in that 7-day period, to take a dose in the absence of RAI. Furthermore, if no RAI activity occurs at all in a given 7-day period, participants will be instructed to take a dose on the seventh day in the absence of RAI.
