简要总结
This is a feasibility, multi-center, open-label, non-significant risk device study for a non-hormonal contraceptive ring.
详细描述
The purpose of this clinical trial is to assess the ability of Ovaprene™ to prevent sperm from penetrating midcycle cervical mucus. In addition, safety, release of ingredients, acceptability and fit will be assessed.

排除标准
- •History of hysterectomy
- •Vasectomy in male partner
- •Sterility or known history of sperm dysfunction in male partner
- •Within two calendar months from the last pregnancy outcome. Note: If recently pregnant must have had at least two spontaneous menses since pregnancy outcome.

- •Either device does not appropriately fit volunteer, as determined by clinician
- •Inability of the volunteer to insert, position, and/or remove either device, even with assistance
- •History of sensitivity/allergy to nonoxynol-9 or to silicone or any other component of Ovaprene™ or Caya, for either the volunteer or her male partner
- •In the last four months, either the volunteer or her male partner diagnosed with or treated for any STI or pelvic inflammatory disease. Note: Women or male partners with a history of genital herpes or condylomata who have been asymptomatic for at least six months may be considered for eligibility
- •Positive test for Trichomonas vaginalis, Neisseria gonorrhea, Chlamydia trachomatis, or HIV
- •Deep epithelial genital findings such as abrasions, ulcerations, and lacerations, or vesicles suspicious for a sexually transmitted infection

- •History of gynecological procedures (including genital piercing) on the external genitalia, vagina or cervix within the last 14 days
- •Abnormal finding on laboratory or physical examination or a social or medical condition in either the volunteer or her male partner which, in the opinion of the investigator, would make participation in the study unsafe or would complicate interpretation of data
- •Nugent score greater than or equal to 7
- •Systemic use in the last two weeks or anticipated use during the study of antibiotics (other than those used to treat urinary tract infection (UTI), vaginal candidiasis, or bacterial vaginosis (BV) diagnosed at Visit 1, or to treat UTI or vaginal candidiasis after Visit 1) or topical antivirals (e.g., acyclovir or valacyclovir). Note: Participants should avoid non-steroidal anti-inflammatory drugs (NSAIDs) and Tylenol except for occasional use, as in treatment of headaches or dysmenorrhea.
- •Grade 2 or higher abnormality per the March 2017 update of the Division of AIDS (DAIDS), National Institute of Allergy and Infectious Disease (NIAID) Table for Grading of the Severity of Adverse Events or clinically significant lab abnormalities as determined by the investigator (see Section 13.5 for link to DAIDS table)
- •Inability to achieve adequate cervical mucus in two attempts at the baseline cycle
- •Inadequate sperm in endocervical aspirate during baseline testing without any device, despite adequate mucus and presence of sperm in vaginal pool
研究组 & 干预措施
Healthy Sexually Active Women
Other
Healthy, sexually active women who are not at risk for pregnancy due to previous female tubal sterilization will receive both Ovaprene and the Caya diaphragm throughout the course of the trial. The purpose of the Caya Post Coital Test (PCT) cycle is to ensure that in this study population and at these sites, results that are expected to be observed in a PCT cycle with an approved vaginal barrier can be replicated.
干预措施: Ovaprene (Device)
结局指标
主要结局
Changes From Baseline in the Post Coital Test Results (PCT) Due to Device Use.
时间窗: Baseline to OVP PCTa at 175 Days
All participants had fewer than 5 progressively motile sperm per high power field (PMS/HPF) in all cycles during Ovaprene use.
