Filter by:This study will enroll approximately 100 HIV-negative persons, aged18-45 years, and assigned female sex at birth from sites in the United States, Kenya, South Africa, and Zimbabwe. The study will assess the acceptability and safety of two placebo vaginal films. The placebo films do not contain any active medication, are the same size, but differ by shape (square versus rounded corners). Participants will be randomly assigned to one of the two films and asked to use (self-insert) the assigned film two times (approximately one month apart). Participants will be asked to refrain from sexual activity during the first month of use and may resume usual sexual activity during the second month of use. The study involves answering questions, undergoing pelvic examinations, and collecting blood and vaginal fluid samples. The study involves a total of 10 visits/contacts, including in person visits and telephone calls over approximately 9 weeks. In addition, both participants and approximately 30 of their sexual partners will be asked to take part in in depth interviews to further assess acceptability, attitudes, and experiences with film use to gauge interest in the future use of vaginal films as a HIV prevention option.
