Ovaprene Human Proof of Concept
Study 2009 - Postcoital Assessment:1 Open-label, single-arm, pilot safety and tolerability study. Published in the Journal of Reproductive Medicine, 2009. Patients: N= 21; all women completed one cycle of use. Results: Postcoital testing revealed no
viable sperm in the cervical mucus. No colposcopic abnormalities, no significant changes in vaginal flora and no serious adverse effects observed. Ovaprene successfully prevented sperm from reaching the cervical canal in a previous human
postcoital test clinical study. In PCT studies of similar size, products (diaphragms) with no motile sperm in the cervical mucus during their PCT assessments demonstrated "typical use" contraceptive effectiveness of 88% in pivotal
contraceptive studies evaluating pregnancy rates over time. Journal of Reproductive Medicine 2009; 54: 685-690 Trussell J. Contraceptive Efficacy. In Hatcher RA, Trussell J, Nelson AL, Cates W, Kowal D, Policar M. Contraceptive Technology:

Ovaprene Regulatory Strategy Step 1
- 2018 / 2019 - Postcoital test (PCT) The study is enrolling 50 couples, with the woman to be evaluated over the course of five menstrual cycles, with a target of having 25 women complete a total of 21 visits. Each woman's cervical mucus
will be measured at several points during the study: Cycle 1 - Baseline measurement (excludes the use of any product). Cycle 2 - Use of a barrier method (diaphragm) Cycles 3,4 and 5 - Ovaprene vaginal ring Assess motile sperm per high powered
field (HPF) in the cervical mucus, post coitus Safety assessments, PK, acceptability, fit, and ease of use *Dare has not had any communications with the FDA regarding the specific PMA requirements for Ovaprene. Data from the study is expected
to be available in the second half of 2019. If there is demonstration of feasibility in the PCT clinical trial, the Company intends to prepare and file an Investigational Device Exemption (IDE) with the FDA to commence a pivotal clinical trial to
support marketing approvals of Ovaprene in the United States, Europe and other countries worldwide. U.S. Regulatory Strategy - (PMA) with CDRH (medical device division) as lead review division (Pathway expected to be based on similar CDRH approvals

(FSAD) FSAD is characterized primarily by an inability to attain or maintain sufficient physical sexual arousal that causes distress or interpersonal difficulty. Estimated 23-33% of women with low arousal Meta-analysis of 95 studies from 2000-2014
indicated the prevalence of Female Sexual Dysfunction in premenopausal women worldwide is 40.9%, and difficulty with arousal alone is 23%.1 33% of women in the U.S. age 21 to 60 (approximately 20 million women), experience symptoms of low or no
sexual arousal. 2,3 10 million women distressed and actively seeking treatment 2 McCool et al. Sex Med Rev 2016;4:197-212. Ad Hoc Market Research: FSAD Prevalence Report (Oct 2015) conducted for SST LLC. Based on US Census projections for 2016.
