DARE-BV1 Clindamycin 2% gel for Bacterial Vaginosis

Successful Proof of Concept • Vaginal application of DARE-BV1 (clindamycin phosphate 2%) demonstrated effectiveness against BV in a proof-of-concept investigator-initiated study in women (n=30):1 • 86% of evaluable subjects met clinical cure endpoint at Test-of-Cure visit after single dose administered • Favorable efficacy profile over currently approved treatments 505(b)(2) Regulatory Pathway • QIDP Designation • Five-year exclusivity extension added to any exclusivity for which a QIDP qualifies upon FDA approval. • Eligible for Fast Track designation and Priority Review. • Single Phase 3 clinical trial planned to support New Drug Application (NDA) for FDA approval – topline data anticipated by end of 2020. Attractive Market Opportunity • BV is the most common vaginal infection in women ages 15-44 2 • U.S. prevalence estimated to be ~21 million among women ages 14-49 2 • Approved prescription drugs have less than optimal clinical cure rates (37-68%) 3 • Opportunity for significant upside and market expansion Patent Coverage • Patents covering the licensed technology have been granted with terms through 2028 • Additional patents pending would have terms through 2035 1.

Therapeutic cure was a composite endpoint, which required both clinical cure (defined as resolution of all 4 Amsel criteria) and bacteriologic cure (Nugent score < 4). Bacteriologic cure required a Nugent score < 4. 8 2. Amsel & Gram Stain Criteria: https://www.cdc.gov/std/tg2015/bv.htm

Hormone Mediated CNS Mediated PDE5 Inhibitor Vulvar-Vaginal Hypoactive Sexual Female Sexual Dyspareunia Desire Disorder Atrophy (HSDD) Arousal Disorder (FSAD) No Approved Products Of the various types of female sexual dysfunction disorders, FSAD is most analogous to erectile dysfunction (ED) in men and is characterized primarily by an inability to attain or maintain sufficient genital arousal during sexual activity that causes distress or interpersonal difficulty. Despite several approved prescription products for ED, no pharmacologic options have yet been approved by the FDA for FSAD. Sildenafil, the active ingredient in Sildenafil Cream, is marketed in an oral dosage form under the brand name Viagra® for the treatment of ED in men. With its approval of Addyi®, FDA acknowledged and formally classified the distinct and separate disorders that comprise Female Sexual Dysfunction. Where HSDD is characterized primarily by a lack of sexual desire, FSAD is characterized primarily by an inability to attain or maintain sufficient physical sexual arousal.

FSAD is characterized primarily by an inability to attain or maintain sufficient physical sexual arousal; it is also characterized by distress or interpersonal difficulty.* • Estimated 23-33% of women suffer from arousal disorder: • 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 are considered distressed and actively seeking treatment.2 *Diagnostic and Statistical Manual 4th Edition Text Revision (DSM IV TR), defines female sexual arousal disorder as a persistent or recurrent inability to attain or to maintain until completion of the sexual activity, an adequate lubrication-swelling response of sexual excitement. The diagnostic criteria also state that the inability causes marked distress or interpersonal difficulty, is not better accounted for by another Axis I disorder (except another sexual dysfunction) and is not due exclusively to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition. 1.

Positive Data - Thermography Study “The results from the first six subjects to complete all assessments indicate the utility of thermography technology to detect statistically meaningful differences in genital temperature changes, a surrogate for genital blood flow, and support the ongoing evaluation of Sildenafil Cream as a treatment for FSAD.” Dr. Tuuli Kukkonen, C.Psych., an Associate Professor in the Department of Family Relations and Applied Nutrition at the University of Guelph in Ontario, Canada • Thermography utilizes sensitive cameras capable of detecting and recording temperature variations over time. • Genital temperature changes are a surrogate for genital blood flow. Sildenafil Cream • Study Design & Methodology (N=6)1 • Phase 1, single-dose, double-blind, placebo-controlled, 2-way crossover study evaluating the feasibility of using thermography to assess the pharmacodynamics of Sildenafil Cream, 3.6% in normal healthy women. • The study consisted of three phases, Screening Phase (Visit 1), the Double-Blind Dosing Phase (Visits 2-3) and a Safety Follow-up Phase Placebo Cream (Phone Call). • Findings: • The thermography study yielded positive findings for Sildenafil Cream, 3.6% (blue line), as shown in Figure 1. • Positive cognitive arousal responses were noted. • Significantly greater increases in genital temperature after application of Sildenafil Cream compared to placebo cream and no cream. Sildenafil Cream produced a statistically significant greater linear slope • Significantly greater self-reported arousal responses reported during during minutes 11-15 of the sexually explicit stimuli as compared to the Sildenafil Cream visits compared to placebo cream visits. placebo cream for the vestibule. 24 1.

Microchips Program User-Controlled Long Acting Reversible Contraception (UC-LARC)

How the Microchips Technology is Designed to Work Drug Storage • Individual doses are stored in micro-reservoir arrays • Reservoirs are hermetically sealed at room temperature • Thin metallic membranes over each reservoir protect drug post-sealing Drug Release • Drug doses are initiated automatically on schedule or wirelessly on- demand by patient or clinician • Reservoirs are opened via electrothermal ablation of membranes • Upon opening, interstitial fluid diffuses in and drug diffuses out 28

The Bill & Melinda Gates Foundation has strong interest in family planning. An estimated 215m women in developing countries don’t have access to contraception.

DARE-VVA1 (Tamoxifen) Vaginally Delivered Tamoxifen to treat VVA in Hormone-Receptor Positive (HR+) Breast Cancer Patients • DARE-VVA1 • A proprietary formulation of tamoxifen for vaginal administration. • Potential to be the first treatment specifically approved for the treatment of vulvar and vaginal atrophy (VVA) in patients with hormone-receptor positive (HR+) breast cancer. • VVA is a chronic condition characterized by pain during intercourse, vaginal dryness and irritation. • Most women use localized estrogen therapy which is contraindicated for the more than two million women diagnosed with, or at risk of recurrence of, ER-positive and PR-positive breast cancer.1 • Daré intends to develop this novel local application of tamoxifen to mitigate the symptoms of VVA for patients with or at risk for HR+ breast cancer, including women currently on anti-cancer therapy. • Due to the use of aromatase inhibitors for the treatment of HR+ breast cancer, the prevalence of VVA in postmenopausal breast cancer patients is estimated to be between 42 and 70 percent.2 35 1. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2800285/#S16title 2.

DARE-VVA1 (Tamoxifen) Vaginal Tamoxifen – Proof of Concept Study1 This exploratory study in four postmenopausal women diagnosed with VVA demonstrated that a self-administered vaginal suppository containing tamoxifen (20mg) dosed daily for one week and twice weekly for three months was effective in reducing vaginal pH and vaginal dryness. Vaginal Tamoxifen Enrollment On Treatment Paired Difference (Baseline) (Month 3) (Baseline vs. Month 3) 7.1 5.0 -2.0 median Median Vaginal pH range 6.5 to 7.5 range 5.0 to 5.2 range -2.5 to -1.5 Lower pH value is a measure of symptom relief Normal vaginal pH is usually less than 4.5.2 Vaginal Dryness 8.0 3.0 -5.5 median Rated using a visual analogue scale (VAS) that ranged from: range of 7.5 to 9.0 range 2.0 to 3.0 range -6.0 to -4.5 0 = Not bothered by dryness 10 = Extremely bothered by dryness Decreased vaginal dryness is a measure of symptom relief In addition, systemic absorption of tamoxifen was not significant. • After 8 weeks of study treatment with vaginal tamoxifen, the median plasma concentration of tamoxifen was 5.8 ng/ml, with a range of 1.0 to 10.0 ng/ml • In comparison, after 3 months of administration of 20mg, once-daily oral tamoxifen citrate (Nolvadex),3 the average steady state plasma concentration of tamoxifen is 122 ng/ml with a range of 71 to 183 ng/ml 1.
