Promoting CSD500 Use Among Women in Established Relationships

2016-10-18 02:08:21 | BioPortfolio


Globally, women in established relationships remain at risk for unintended pregnancy and sexually transmitted infections (STIs), including HIV. In Vietnam, the location of the proposed research, unmet need for contraception is substantial as reflected in the nation's high abortion ratio. Married women account for about one-third of HIV cases in Vietnam, and among this group, most were exposed to the virus through sexual activity with their husband. Condoms will remain crucial for prevention for some time to come. Sustained condom use, however, is notoriously difficult to achieve. A key barrier to the consistent use of condoms is their effect on sexual pleasure. Although sexual pleasure is a primary motivation for engaging in sex and is an integral part of overall sexual health, most programs to improve sexual health operate within a pregnancy and disease-prevention paradigm. A new condom, CSD500, containing an erectogenic drug was developed for use among healthy couples to improve sexual pleasure by increasing penile firmness, size and erection duration. The overall objective of the proposed two-arm randomized trial is to test whether promoting the novel condom CSD500 for improved sexual pleasure results in couples having less unprotected vaginal sex. Investigators will measure the occurrence of unprotected vaginal sex by testing women's vaginal fluid for the presence of prostate-specific antigen (PSA), an objective, biological marker of recent semen exposure. Investigators will randomize 500 adult, heterosexual, monogamous couples in Thanh Hoa province, Vietnam to receive either CSD500 for sexual pleasure or the standard condom currently provided only for pregnancy and disease prevention to patients during routine care. Study staff will interview female participants at enrollment and after 2, 4, and 6 months and their male partners at the 6-month visit. Study clinicians will sample vaginal fluid from female participants at all visits to test for the presence of PSA.


This randomized controlled trial will test whether promoting the novel condom CSD500 (Futura Medical Developments; Surrey, UK) for improved sexual pleasure results in couples having less unprotected vaginal sex - measured with a biological marker of recent semen exposure - compared to the promotion of a standard condom for disease and pregnancy prevention. CSD500 contains an erectogenic drug and was developed to improve sexual pleasure by increasing penile firmness, size, and erection duration.

Investigators will recruit eligible, monogamous, heterosexual couples at Thanh Hoa Provincial Centre of Reproductive Health in Vietnam to participate in a randomized controlled trial (RCT) of two balanced arms of approximately 250 couples each. At enrollment and at three follow-up visits scheduled at 2, 4 and 6 months after enrollment, study staff will provide condom counseling, will collect vaginal swabs to test for the semen biomarker, prostate-specific antigen (PSA), and will administer a questionnaire to the female participants on their demographics, sexual and condom-related attitudes and practices, including sexual pleasure and perceptions of partner's sexual pleasure. Although the intervention is directed to the women, couples will be enrolled to ensure that the male partners consent to CSD500 use. After enrollment, male participants will not participate in study visit activities, including data collection, until the time of their female partner's final 6-month visit. Because of the differences in counseling messages, participants and study staff at the site cannot be blinded to arm assignment.
