Safety and Acceptability of Carraguard™ Among HIV-negative Couples in Thailand
The primary aims of the study were to assess the safety and acceptability of Carraguard applied vaginally prior to sexual intercourse for six months in both women and men; and to examine several dimensions of acceptability. Secondary aims were to gauge reactions to a non-contraceptive microbicide, to assess use dynamics among Thai couples and to observe preliminary indications of sexually transmitted infections and reproductive tract infections averted.
The hypothesis was that Carraguard would cause little or no significant irritation, including lesions; and that women and men would find Carraguard acceptable.

|Official Title:||A Randomized, Placebo-controlled, Double-blind Trial to Assess Expanded Safety and Acceptability of Carraguard™ (PC-515) Vaginal Gel Among Heterosexual Couples in Chiang Rai|
- Safety (toxicity/local irritation): Genital exam and interview for signs and symptoms, 14-days after enrollment and monthly thereafter for 6 months; testing for bacterial vaginosis and candida (women) and balanitis (men) monthly.
- Acceptability: Interview about gel use to assess compliance (monthly) and acceptability (quarterly).
- Preliminary effectiveness: Swabs taken from women an urine specimens collected from men to test for sexually transmitted infections - gonorrhea, chlamydia, trichomoniasis (monthly) and for genital ulcer disease, if ulceration was detected; blood drawn

Carraguard™ (PC-515), the Population Council's lead candidate microbicide, was tested in a triple-masked, randomized, placebo-controlled trial fielded in one site in Chiang Rai, northern Thailand. The primary aims of the study were to assess Carraguard's safety (toxicity) in both men and women - including signs of local irritation, such as itching or burning; changes in vaginal flora (women); and incidence of abnormal external genital, vaginal (women), and cervical findings (women) - when applied vaginally prior to intercourse for 6 months; to evaluate acceptability; to gauge men's and women's reactions to a non-contraceptive microbicide; and to explore microbicide use dynamics in a Thai population.
Secondary aims were to investigate sexually transmitted infections averted - including HIV, C. trachomatis, N. gonorrhoeae, T. vaginalis, and T. pallidum (preliminary indications) in men and women; bacterial vaginosis and candidaisis in women; and balanitis in men; and effect on cervical cytology.
