Clinical Trial Summary

This is a research study to determine whether bacterial vaginosis (BV) changes the cervico-vaginal tissue (skin covering the cervix and vagina) and makes women at higher risk for getting HIV (Human Immunodeficiency Virus). Vaginal and cervical tissue biopsies from women with BV will be obtained and infected OUTSIDE the body (ex vivo) with HIV.

BV is a vaginal infection that develops when there is an imbalance in the normal bacteria found in a woman's vagina. It is the most common cause of vaginal discharge among women of child-bearing age. BV infections potentially harm the safety of the tissue surrounding the cervico-vaginal region. When the cervico-vaginal tissue is not well protected, the risk of acquiring HIV from an infected partner might increase significantly. Studies have shown that HIV is more common in women with BV than in women with normal vaginal bacteria.

Treatment of BV typically involves the use of antibiotics. Antibiotics kill harmful bacteria and provide a temporary relief from the symptoms caused by the infection. Women participating in this study will use the generic antibiotic metronidazole, also known as Flagyl. The Center for Disease Control and Prevention (CDC) recommends Flagyl for the treatment of BV.

The study will evaluate HIV infection and safety of cervico-vaginal tissue in women at 3 different time periods:

1. During a BV infection

2. Approximately 1 week after completing a 7-day course of metronidazole therapy

3. Approximately 1 month after completing the 7-day course of metronidazole therapy

You will not come in contact with HIV during this study - only your samples (after we have removed them from your vagina/cervix) come in contact with HIV.


Clinical Trial Description

WHY ARE YOU BEING ASKED TO TAKE PART?

You are being asked to participate in this research project because you are a female between the ages of 18-50 and you think you might have a current BV infection; your menstrual cycle is regular and your last two periods were 21-35 days apart; you are willing comply with the procedures done at 3 study visits; and you are willing to take metronidazole for 7 days.

This study includes only people who voluntarily choose to take part. Please take your time to make your decision and feel free to ask any questions you might have.

WHAT ARE SOME IMPORTANT DETAILS ABOUT THIS STUDY?

Up to approximately 80 women are expected to take part in the study at this local site. There are no other study sites participating in the study. You will have three scheduled visits to the clinic. Your participation in the study will last for approximately 2 months.

WHEN SHOULD YOU NOT TAKE PART?

You should not take part in this study if you:

- Drink alcohol on a daily basis and are unwilling to abstain from alcohol while taking metronidazole.

- Have a known allergy to metronidazole.

- Have chronic immune suppression (including, but not limited to, chronic steroid use, chronic anti-fungal use, Diabetes Mellitus, organ transplant).

- Had an abnormal documented Pap smear in the past 12 months.

- Had your last Depo medroxyprogesterone acetate (DMPA) injection less than 3 months ago and you have not had 2 normal menses since then.

- Used any hormonal contraceptive method within the past 2 months.

- Used oral or vaginal antibiotics or anti-fungals in the last 14 days.

- Had surgery or biopsy of the vulva, vagina, or cervix within 30 days.

- Had a hysterectomy.

- Were pregnant within the past 3 months.

- Are currently breastfeeding.

- Are HIV-1 positive, or your current sexual partner(s) is.

- Use daily anti-viral suppression medications for Herpes Simplex Virus (HSV).

- Believe you currently have a sexually transmitted infection.

- Used a douche or other vaginal products or put anything in your vagina in the past 48 hours; have a current presence of vulvar, anal and or vaginal genital warts.

- Have had vaginal intercourse with a male partner within the last 48 hours.
