简要总结
The purpose of this study is to evaluate the safety and pharmacokinetics of PC-1005 gel when used as a rectal microbicide in HIV-uninfected men and women (cis or transgender) with a history of consensual receptive anal intercourse.
详细描述
PC-1005 is a multipurpose prevention technology (MPT) microbicide in development that is active against HIV, HPV, and HSV-2. This study will evaluate the safety and pharmacokinetics of PC-1005 gel when administered rectally.
The study will enroll HIV-uninfected men and women (cis or transgender) with a history of consensual receptive anal intercourse. All participants will receive 3 single escalating doses of rectally administered PC-1005: 4 mL, 16 mL and 32 mL.
The study includes a total of 9 clinic visits and 1 follow-up contact by phone or in person. Participants will receive doses of PC-1005 at Visits 3, 5, and 7. A 2-to-6 week washout period will follow each dosing visit. If no adverse events that preclude continuation to the next dose are identified during this period, participants will receive the next scheduled dose of PC-1005. Participation in this study will last approximately 3 to 5 months.
Study visits will include physical examinations, throat swabs, behavioral assessments and interviews, and collection of blood, urine, rectal tissue, and cervical, vaginal, and rectal fluid.

- •History of inflammatory bowel disease by participant report
- •* As per the Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events Corrected Version 2.1, July 2017
- •Note: Otherwise eligible participants with an exclusionary test result can be re-tested during the screening process. If a participant is re-tested and a non-exclusionary result is documented within 45 days of providing informed consent for screening, the participant may be enrolled.
- •Known adverse reaction to latex or polyurethane (ever)

- •Anticoagulant medications
- •Rectally-administered medications
- •Known adverse reaction to any of the components of the study product
