BufferGel is a new contraceptive gel designed to be used with a diaphragm. In addition to preventing pregnancy, BufferGel may also prevent some types of sexually transmitted diseases (STDs). This study will compare BufferGel to Gynol II, a currently available contraceptive gel.
Vaginal acidity is thought to be one means by which the vagina prevents overgrowth or colonization by harmful microbial flora. Sperm and many STD pathogens, including HSV-1 and HSV-2, Neisseria gonorrhoeae, Treponema pallidum, Haemophilus ducreyi, and a variety of bacterial vaginosis-associated bacteria, are inactivated at pH less than 5 in vitro. BufferGel, a vaginal spermicide and microbicide, is an acidic buffer that maintains the vagina at or near its natural state of mild acidity. Formulated at vaginal pH (pH 3.9), BufferGel prevents or limits the semen-induced rise in vaginal pH. Carbopol 974P, the buffering agent in BufferGel, is a high molecular weight, cross-linked, polyacrylic acid used as a gelling or tableting agent in many pharmaceuticals; it has a well-documented record of mucosal safety in animals and humans. This study will determine the safety and contraceptive efficacy of BufferGel spermicide used with a diaphragm compared to Gynol II spermicide used with a diaphragm. The study will also measure the frequency of bacterial vaginosis, urinary tract infections, and cervical lesions in women using BufferGel compared with Gynol II.
Participants in this study will be fitted for a diaphragm and randomized to receive either BufferGel or Gynol II. All participants will be instructed on the use of the test product with the diaphragm. Participants will be followed through 6 menstrual cycles (approximately 7 months) and will have 4 study visits and one study phone call. Some participants may enroll in an extended version of the study and be followed for an additional 6 cycles and 2 additional study visits. Study visits will include a gynecologic exam, Pap smear, and blood and urine tests. Participants will be asked to keep a diary to record information on product use. Some participants may also be asked to enroll in a colposcopy substudy. These participants will undergo colposcopy at study entry and after cycles 1, 3 and 6.

Participant's Sexual Partner Must Not Be/Have
Exclusion Criteria
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
