A Study of BufferGel in Women

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: Female

Summary

The purpose of this study is to see if it is safe to use BufferGel in the vaginas of women who do not have HIV and who have a low risk of getting HIV.

Many new cases of HIV are the result of heterosexual activity. Condom use is currently the only effective way of preventing the spread of HIV and other sexually transmitted diseases (STDs). However, women, who have a greater risk of getting HIV, are often unable to convince their partner to use a condom. Therefore, it is important to develop methods that prevent the spread of HIV and that are controlled by the woman, such as medicines used in the vagina. BufferGel is known to kill the organisms that cause STDs, including HIV. BufferGel may do this without causing genital irritation and sores as other medicines do. More studies are needed to see if this is true.
