BV is the most commonly reported vaginal infection in women ages 15-44.1 BV is characterized by a shift in the vaginal flora from the dominant Lactobacillus to a polymicrobial flora.2 BV has been associated with serious health issues, including preterm births, pelvic inflammatory disease, increased susceptibility to sexual transmitted infections (including HIV infection) and other chronic health problems.1,2 A number of potential microbial pathogens, singly and in combinations, have been implicated in the disease process. The list of possible agents includes Gardnerella, Atopobium, Prevotella, Peptostreptococcus, Mobiluncus, Sneathia, Leptotrichia, Mycoplasma, and BV-associated bacterium 1 (BVAB1) to BVAB3.1 Bacterial Vaginosis (BV) Symptoms & Causes of BV Center for Disease Control and Prevention (CDC). www.cdc.gov/std/bv/stats.htm Onderdonk, A. et al. “The Human Microbiome during Bacterial Vaginosis,” Clinical Microbiology Reviews, April 2016 Volume 29 Number 2

BV is characterized by the presence of three of the following four criteria: Vaginal pH of >4.5 Clue cells on saline wet mount Release of a fish amine odor, A characteristic thin, homogenous vaginal discharge. In 1991, Nugent et al. described a Gram stain scoring system of vaginal smears to diagnose BV. 1,3 The Nugent score is calculated by assessing for the presence of large gram-positive rods (Lactobacillus morphotypes; decrease in Lactobacillus scored as 0 to 4), small gram-variable rods (G. vaginalis morphotypes; scored as 0 to 4), and curved gram-variable rods (Mobiluncus spp. morphotypes; scored as 0 to 2) and can range from 0 to 10. A score of 7 to 10 is consistent with BV. 1,3 BV is not considered to be a sexually transmitted infection, but it is more common in women who are sexually active. Bacterial Vaginosis (BV) Symptoms & Causes of BV Sha, Beverly E., et al. “Utility of Amsel Criteria, Nugent Score, and Quantitative PCR for Gardnerella vaginalis, Mycoplasma hominis, and Lactobacillus spp. for Diagnosis of Bacterial Vaginosis in Human Immunodeficiency Virus-Infected Women.“ JOURNAL OF CLINICAL MICROBIOLOGY, Sept. 2005, p. 4607–4612 https://www.keepherawesome.com/bacterial-vaginosis Wilson, J. “Managing recurrent bacterial vaginosis.” Sexually Transmitted Infections. 2004; 80(1): 8–11.. 2

In the US, an estimated 21 million women aged 14-49 years (approximately 29%) are infected with BV.1,2 BV leads to symptoms including abnormal vaginal discharge and odor that are unpleasant and disrupt and interfere with a woman’s relationships and general quality of life. According to IMS/IQVIA data, the 2016 U.S. annual sales figures for BV prescriptions were in excess of $150 million including utilization of oral and vaginal forms of Clindamycin and Metronidazole.3 Starpharma’s VivaGel® has a PDUFA date scheduled for January 2019 (BV treatment and prevention).4 Lupin’s 1x oral Solosec® launched in May of 2018.5 Bacterial Vaginosis Market Opportunity https://www.cdc.gov/std/bv/stdfact-bacterial-vaginosis.htm; Sucher, Allana et al., “Bacterial Vaginosis: A Review,” US Pharmacist 2018: 43(9):32-33 IMS/IQVIA data (2016).

DARE-BV1 met clinical cure endpoint in a proof-of-principle investigator initiated clinical study for the treatment of BV. Novel proprietary hydrogel-based drug delivery technology has been developed for use in intravaginal and urology applications. Designed to improve efficacy through unique features: in-situ gelation, sustained erosion and adhesion at the site of administration. DARE-BV1 utilizes a proprietary drug delivery platform to deliver 2% clindamycin intravaginally. Novel formulation is designed to improve efficacy following single administration due to optimal dual release sustained-erosion of clindamycin. Primary efficacy endpoint met in a proof-of-principle investigator initiated study in 30 women: 88% of evaluable subjects met clinical cure endpoint at Test-of-Cure visit. 505(b)(2) regulatory pathway enables concise clinical development plan: NDA filing with FDA planned following successful completion of a single, ~250 subject pivotal study. Patents covering the licensed technology have been granted with terms through 2028 and additional patents pending would have terms through 2035.

Female Sexual Arousal Disorder (FSAD) 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 Female Sexual Arousal Disorder FSAD 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. *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.

Continue to explore additional clinical and non-clinical work that might be valuable or required to support the overall program and the anticipated design of the Phase 2b. Planned Type C Meeting Content Validity Initiated (4Q 2018) At Home Study 2b At Home Study Topline Data – 4Q 2020 A content validity study is designed to help ensure the concepts we plan to measure are the most important and relevant to our target population.  It is a focus group type study where in-depth one-to-one interviews are conducted with individuals who have FSAD. The interviews are conducted in a population that, as closely as is reasonable, matches the proposed clinical trial population.  It includes an open-ended discussion in which the participant will be asked about their experience of sexual arousal problems and any associated impact. In addition, the participant will be asked to complete the PRO instrument proposed to be used in the Phase 2b and Phase 3 clinical trials, to provide feedback on the relevance of the questions in the PRO instrument and on the clarity and understandability of all questions, instructions, and response options. This is a non-interventional study – participants will not be asked to use or evaluate any products. Because our plan is for the endpoints used in the Phase 2b to reflect the endpoints used in the Phase 3 trials, after the content validity study is completed, and before we commence a Phase 2b at home trial, we will request at Type C meeting to get feedback on whether the agency agrees that the PRO instruments are content valid for the target population.  The Phase 2b at-home study will allow patients to use the investigational product and placebo in their home setting.  The FDA is agreeable to a 12-week Phase 2b for Sildenafil Cream, 3.6% to assess reasonable safety and preliminary efficacy.  The 2016 Draft Guidance reflects expectations regarding phase 3 study length and patient population.

Vaginally Delivered Tamoxifen to treat VVA in HR+ Breast Cancer Patients DARE-VVA1 (Formerly PT-101) A proprietary vaginal formulation of tamoxifen, has the potential to be a first-in-class treatment for 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 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 hormone-receptor-positive 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 reported to be between 42 and 70 percent.2 If approved, DARE-VVA1 has the potential to be the first treatment specifically developed for VVA in patients with hormone-receptor positive breast cancer.

DARE-RH1 (CatSper) A Novel Approach To Male And Female Contraception. The identification of the CatSper target represents the potential to develop a novel class of non-hormonal contraceptive products for both men and women. The discovery of a sperm-specific ion channel, CatSper, was validated in animal models where it was demonstrated that male mice lacking CatSper have poor sperm motility. CatSper proteins are ion channels expressed solely in the membranes of sperm flagellum and are essential to sperm motility. Pre-clinical research has demonstrated CatSper mediates hyperactive motility of sperm. Sperm hyperactivity is necessary to penetrate the physical barrier known as the zona pellucida which encloses the ovum and protects the egg.1 The contraceptive benefit of targeting CatSper is achieved by inhibiting sperm hyperactivity and preventing egg fertilization.

ORB-204 and ORB-214, injectable etonogestrel1 The initial development on Orbis’ long-acting injectable contraceptive program was carried out under a subcontract funded by Family Health International (FHI 360) through a grant from the Bill & Melinda Gates Foundation. Pre-clinical studies for the 6- and 12- month formulations have been completed to date: Establishing pharmacokinetics and pharmacodynamics profiles. An injectable contraceptive is designed to provide discreet, non-invasive protection over several months Limitations of the currently marketed injectable contraceptive: provides contraceptive protection for only three months, and can delay the ability to get pregnant for up to ten months after receiving the injection. Target product profile of long-acting injectable Prolonged duration (6 to 12 months), improved ease of use, with an improved side effect profile and predictable return to fertility.
