12 DARE-BV1- Phase 3 Study Design & Demographics1 DARE-BV1 is a thermosetting vaginal gel formulated with clindamycin phosphate 2%, a well-known and well-characterized antibiotic designed for prolonged, localized release. ➤DARE-BVFREE randomized 307 women at 32 centers across the US in a 2:1 ratio to receive a single vaginal dose of DARE-BV1 (N=204) or a single vaginal dose of placebo gel (N=103). ➤The intent to treat (ITT) population2 comprised primarily patients aged 15 to 59 years, with a mean age of 34.8 (б=8.8) and median age of 35. Over 53% of the ITT population qualified as obese (BMI ≥30.0), with a mean BMI of 31.50 (б=8.5). ➤In the ITT population, 56.0% of women identified as Black or African American, 41% identified as white and 25.5% identified as of Hispanic or Latino origin (compared to 74.5% as not of Hispanic or Latino origin). ➤In addition, more than 75% of women in the ITT population reported one or more episodes of bacterial vaginosis in the 12 months before they were randomized into the study (77.4% in the DARE-BV1 group and 73.8% in the placebo group). ➤The mITT study population3 also required a Nugent score of 7 or greater at time of randomization per the new 2019 FDA bacterial vaginosis guidance. The DARE-BVFREE study’s two treatment arms were well balanced in terms of age, race, ethnicity, bacterial vaginosis history, and body mass index (BMI). N=307 subjects enrolled (age 15 and above) Duration ~30 days per subject Diagnosis - Bacterial vaginosis Definitions: Primary Endpoint: Clinical Cure (Day 21-30 visit)4: Resolution of the abnormal vaginal discharge associated with BV; Negative 10% KOH “whiff test”; Clue cells < 20% of the total epithelial cells in the saline wet mount. Secondary endpoints: Proportion of subjects with Clinical Cure, Bacteriological Cure and Therapeutic Cure at Day 7-14 Visit5 Bacteriological Cure: a Nugent score < 4. Therapeutic Cure: both a Clinical Cure and Bacteriological Cure. 1. Data on file. 2. ITT population N=307 3. Modified ITT (mITT) population N=180. In accordance with FDA guidance, the mITT population excludes subjects from the ITT population who subsequently demonstrated a positive test result for other concomitant vaginal or cervical infections at baseline. 4.

15 Sildenafil Cream, 3.6% Potential First-In-Category treatment for Female Sexual Arousal Disorder (FSAD), which has no FDA-approved therapies Novel cream formulation of sildenafil to treat FSAD, utilizing active ingredient in Viagra®

Female Sexual Arousal Disorder (FSAD) is characterized primarily by inability to attain or maintain sufficient genital arousal during sexual activity and, of female sexual function disorders, is most analogous to erectile dysfunction (ED) in men.* The condition should be distinguished from a general loss of interest in sexual activity and from other sexual dysfunctions, such as orgasmic disorder (anorgasmia) and hypoactive sexual desire disorder (HSDD), which is characterized as lack or absence of sexual fantasies and desire for sexual activity for some period of time.1,2 16 FSAD – The Clinical Issue FSAD HSDD *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.https://drgeo.com/womens-sexual-health-overview/; 2.https://health.usnews.com/conditions/sexual-disorder-dysfunction

17 FSAD – What is the incidence? Meta-analysis of 95 studies from 2000- 2014 indicated prevalence of Female Sexual Dysfunction in premenopausal women worldwide is 41%, and difficulty with arousal alone is 23%.1 Market research estimates: ➤33% of US women aged 21 to 60 (~ 20 million women), experience symptoms of low or no sexual arousal.2,3 ➤10 million women are considered distressed and actively seeking treatment.2 1.McCool et al. Sex Med Rev 2016;4:197-212. 2.Ad Hoc Market Research: FSAD Prevalence Report (Oct 2015) conducted for SST LLC. 3.Based on US Census projections for 2016.

Topically administered investigational Sildenafil Cream1 is… There are no FDA-approved treatments for FSAD 1.Sildenafil Cream, 3.6%, (formerly SST-6007) 2.https://qz.com/quartzy/1238783/its-the-20th-anniversary-of-viagra-heres-how-its-changed-the- world/#:~:text=Annual%20sales%20of%20Viagra%20peaked,Viagra%20is%20set%20to%20expire .

19 Sildenafil Cream, 3.6% - Phase 2b ➤Compares Sildenafil Cream vs. placebo used in patients’ home setting. ➤Primary endpoint: patient reported outcome (PRO) instruments to measure improvement in localized genital sensations of arousal and reduction in FSAD related distress. ➤Several exploratory efficacy endpoints will be measured and could become additional measurements of efficacy in a future Phase 3 program. Ongoing Phase 2b clinical study aims to evaluate Sildenafil Cream vs. placebo over 12 weeks of dosing following both a non-drug and placebo run-in period.

20 Oral Sildenafil provided a compelling proof of concept for FSAD † Question #2 – “After taking study medication, the sensation/feeling in my genital (vaginal, labia, clitoris) area during intercourse or stimulation (foreplay) seemed to be: (a) more than before, (b) less than before, or (c) unchanged”. Question #4 – “After taking the study medication, intercourse and/or foreplay was: (a) pleasant and satisfying; better than before taking the study medication, (b) unpleasant; worse than before taking study medication, (c) unchanged; no difference, or (d) pleasant; but still not like it used to be or I would like it to be.” 202 postmenopausal women with FSAD who had protocol specified estradiol and free testosterone concentrations, and/or were receiving estrogen and/or androgen replacement therapy were studied. † Twelve healthy premenopausal women were studied.
