PROTOCOL SUMMARY 
4.1 
SYNOPSIS 
Name of Sponsor/Company: 
Daré Bioscience, Inc.  
Name of Investigational Product: 
Clindamycin phosphate vaginal gel, 2% (DARE-BV1) 
Name of Active Ingredient: 
Clindamycin phosphate  
Title of Study:  
A Phase 3 Multi-center, Double-blind, Placebo-controlled, Randomized Study of DARE-BV1 in the 
Treatment of Bacterial Vaginosis 
Study Centers: Approximately 36 sites in the United States 
Study Period: 
The study duration for each patient will be up to approximately 1 month:  
 
Visit 1 (Day 1) screening and randomization, including treatment;  
 
Visit 2 (Day 7-14) interim assessment of efficacy parameters and safety; 
and  
 
Visit 3 (Day 21-30) assessment of clinical cure and safety or the Follow-up 
Safety Phone Visit (Day 21-30) for patients who discontinue prematurely 
from the study. 
For patients in the pharmacokinetics (PK) subset only, there will be additional 
blood draws at Visit 1 (Day 1) as well as 5 additional visits between Visit 1 and 
Visit 2 (Visits PK1-PK5 on Days 2 through 6).  
Phase of 
development: 3 
Objectives: 
Primary: 
Assess the efficacy of DARE-BV1 for the treatment of bacterial vaginosis (BV) in postmenarchal 
females. 
Secondary: 
Assess the safety and acceptability of DARE-BV1. 
Study Design:  
This is a multicenter, randomized, double-blind, placebo-controlled study of DARE-BV1 (clindamycin 
phosphate vaginal gel, 2%) (daily [QD] × 1 day) compared to placebo vaginal gel 
(hydroxyethylcellulose [HEC] Universal Placebo Gel) (QD × 1 day) for the treatment of BV. Patients 
will be evaluated at 3 time points: a Day 1 Screening/Randomization visit, a Day 7-14 Interim 

Clinical Study Protocol 
DARE-BV1-001

Assessment visit, and a Day 21-30 Test of Cure [TOC] visit). Patients who discontinue prematurely 
from the study will receive a safety follow-up phone call between Day 21-30. The total study duration 
will be up to approximately 1 month for each individual patient. 
The date of the patient’s last menstrual period and expected timing of her next menses will need to be 
taken into consideration prior to scheduling the Screening/Randomization Visit to ensure the patient is 
not menstruating at the time of the visit, nor expected to start menstruating during the first 7 days after 
study drug administration. In the event that the patient is found to be menstruating at the time of the 
initial Screening/Randomization Visit, or is due to start menstruating within 1 week of the visit, then 
randomization should be delayed. Split screening visits are therefore allowed (while noting protocol 
requirements for those assessments that must be repeated or delayed until the day of randomization). 
At the Screening/Randomization Visit (Day 1), past medical and obstetrical/gynecological history, 
contraception and medically relevant sexual history, and number of episodes of BV in the preceding 
12 months (along with treatment given) will be collected/evaluated. Signs and symptoms of BV will be 
evaluated, including color, odor, and consistency of vaginal discharge, plus vulvovaginal itching and 
irritation will be assessed. Additionally, the following samples/tests will be collected and performed: 
saline wet mount to assess clue cell percentage, 10% potassium hydroxide (KOH) “whiff test” and 
KOH wet mount microscopy for yeast assessment, vaginal culture for Candida species, vaginal pH, 
preparation of slides for centralized Gram stain for Nugent scoring, urine pregnancy test, nucleic acid 
amplification tests (NAATs) for Chlamydia trachomatis and Neisseria gonorrhoeae, OSOM® test for 
Trichomonas vaginalis, blood sample for chemistry and hematology, and urinalysis.   
Patients will be provided with instructions for using a daily electronic diary (eDiary). The patient 
eDiary will be utilized to collect information regarding study drug administration, symptoms related to 
BV, relevant adverse events (AEs) and other pertinent information. 
Eligible patients will be randomly assigned via Interactive Response Technology (IRT) to one of the 
following treatment groups (2:1): clindamycin phosphate vaginal gel, 2% (DARE-BV1; 1 dose is 5 g 
gel = 100 mg clindamycin) QD × 1 day, or placebo vaginal gel (Universal HEC Placebo Gel, 5 g), 
QD × 1 day. Study drug will be applied intravaginally within 1 day of randomization. 
The patients will return to the clinic for Visit 2 on Day 7-14 for the Interim Assessment. A third and 
final visit will be conducted at Day 21-30 for TOC. Similar to the requirement at randomization, 
patients should not be actively menstruating on the day of the Interim or TOC Visit, although the TOC 
Visit should take priority, if scheduling around menses is challenging. At both the Visit 2 (Day 7-14) 
and Visit 3 (Day 21–30) visits, the Investigator will perform gynecological examinations and collect 
specimens for the following tests: saline wet mount to assess clue cell percentage, 10% KOH whiff test 
and wet mount microscopy for yeast assessment, vaginal pH, preparation of slides for the centralized 
Gram stain for Nugent Scoring, urinalysis, and urine pregnancy test. Additionally, the signs and 
symptoms of BV including color, odor, and consistency of vaginal discharge, plus vulvovaginal itching 
and irritation will be evaluated at each visit. Post-treatment blood chemistry and hematology 
assessments will be obtained at the TOC Visit (Visit 3, Day 21-30). Repeat testing for N. gonorrhea, 
C. trachomatis, T. vaginalis or Candida species may be obtained at any time if clinically warranted to 
determine the etiology of a change or worsening in vaginal discharge or other signs or symptoms.  
Assessment and documentation of AEs and concomitant medications will occur at each visit. A review 
of patient-reported and Investigator-assessed local site reactions will occur at each visit after 
randomization and treatment. 
Approximately 20 patients at selected sites (2-4 sites are anticipated) will participate in a PK study. The 
patients in this subset will apply the study drug during Visit 1 at the study clinic and will have blood 
draws for plasma clindamycin assessment taken at 0 hours (pre-dose) and then at 2, 4, 6, and 8 hours 
(± 15 minutes) post-dose, as well as at 24, 48, 72, 96, 120, and 144 hours (±2 hours) post-dose 

Clinical Study Protocol

(Days 2-7). In addition, samples for vaginal clindamycin concentrations will be collected on Days 1-7 
(with the Day 1 sampling schedule starting pre-dose). For these patients, the assessments for the 
Interim Assessment (Day 7-14) visit may be done on the same day as the Day 7 PK sample collection.  
If necessary due to persistent symptoms of BV, patients may be offered other BV treatment prior to 
completion of the study; however, whenever feasible, other therapy should not be initiated until the 
patient has completed the final TOC Visit (Visit 3, Day 21-30). If initiated prior to Visit 3, then the 
patient should remain in the study and return to the clinic for the final TOC Visit (Visit 3, Day 21-30). 
If other BV treatment is prescribed at Visit 3, then the patient should either be followed by the study 
doctor (if the patient is regularly treated at their clinic), or referred back to their local health care 
provider for further follow-up, as appropriate. The choice of other BV therapy is left up to the 
Investigator in collaboration with the patient, based on the current standard of care. Any other 
medications received for treatment of BV should be recorded as concomitant medications.  
The goal is for all patients to complete the study, regardless of whether additional BV treatment, yeast 
treatment or other anti-microbial therapy is required prior to completion of the final TOC Visit (Visit 3, 
Day 21-30). Patients who discontinue prematurely from the study for any reason will receive a Safety 
Follow-up phone call between Study Days 21-30 to assess the status of BV symptoms, AEs, and 
medication usage.  
Primary Efficacy Endpoint: 
 
The primary efficacy endpoint is the proportion of patients with Clinical Cure at the TOC visit 
(Day 21-30). Clinical Cure is defined as: 
o Resolution of abnormal vaginal discharge associated with BV; 
o Negative 10% KOH whiff test; and 
o Clue cells < 20% of the total epithelial cells in the saline wet mount. 
Secondary Efficacy Endpoints: 
 
Proportion of patients with Bacteriological Cure at the TOC visit (Day 21-30). Bacteriological 
Cure is defined as a Nugent score < 4. 
 
Proportion of patients with Therapeutic Cure at the TOC visit (Day 21-30). Therapeutic Cure 
is defined as both a Clinical Cure (defined above) and Bacteriological Cure (Nugent 
Score < 4). 
 
Proportion of patients with Clinical Cure (defined above) at the Interim Assessment visit 
(Day 7-14). 
 
Proportion of patients with Bacteriological Cure (Nugent score < 4) at the Interim Assessment 
visit (Day 7-14). 
 
Proportion of patients with Therapeutic Cure at the Interim Assessment visit (Day 7-14).  
Safety and Acceptability Assessments:

Criteria for Inclusion: 
Diagnosis and Main Eligibility Criteria: 
Patients with a clinical diagnosis of BV (see below) at the Screening/Randomization Visit who meet 
the following eligibility criteria may participate in the study: 
Inclusion Criteria: 
1. Patients must provide written informed consent prior to any study-related procedures being 
performed. Patients from 12 through 17 years old may participate where permitted by 
applicable local regulations and Institutional Review Board (IRB) approval and with 
appropriate documentation of consent from the parent(s)/guardian(s) and assent from the 
patient. 
2. Patients must have a clinical diagnosis of BV, defined as having all of the following: 
a. Off-white (milky or gray), thin, homogeneous discharge with minimal or absent 
pruritus and inflammation of the vulva and vagina 
b. The presence of clue cells > 20% of the total epithelial cells on microscopic 
examination of the saline wet mount 
c. Vaginal secretion pH of > 4.5 
d. A fishy odor of the vaginal discharge with the addition of a drop of 10% KOH (i.e., a 
positive whiff test) 
3. Patients must be females ≥ 12 years of age with no known medical conditions that, in the 
Investigator’s opinion, may interfere with study participation. 
4. Patients must agree to abstain from sexual intercourse and/or sexual activity throughout the 
first 7 days following treatment. Non-pregnant patients must also agree to use adequate birth 
control (see Inclusion Criterion #5) should they later engage in heterosexual intercourse 
through the final study visit (Visit 3, Day 21-30). 
5. This trial will enroll pregnant women; however, non-pregnant patients of childbearing potential 
should use adequate birth control after Day 7 if engaging in heterosexual intercourse, and 
should not plan on becoming pregnant for the duration of the study. Acceptable forms of birth 
control include oral contraceptives (“the pill”), intrauterine devices (IUDs), contraceptive 
implants under the skin, patches or injections, and non-polyurethane condoms (e.g., latex,

be in use for 1 full cycle (e.g., 4 to 8 weeks) prior to study drug application. Injectable or 
implanted contraceptives (e.g., Depo-Provera, Nexplanon, or hormonal IUD) must have been 
injected/inserted at least 7 days prior to study drug application.  
Patients who are not of childbearing potential will not need a urine pregnancy test prior to 
randomization or at subsequent visits.  The patient is considered to be of non-child bearing 
potential if one of the following is satisfied:  
a. Postmenopausal for at least 1 year prior to the Screening/Randomization Visit (Visit 1) 
(defined as amenorrheic for more than 1 continuous year), or 
b. Surgically sterile (defined as bilateral tubal ligation, bilateral oophorectomy, or 
hysterectomy) at least 6 months before first dose, or 
c. Non-surgical permanent sterilization procedure performed at least 3 months prior to 
study drug application. 
6. Patients must be willing to refrain from the use of all intra-vaginal products (e.g., douches, 
feminine deodorant sprays, condoms, spermicides, vaginal moisturizers or lubricants, tampons, 
vaginal birth control rings [e.g., NuvaRing®], and diaphragms) through the first 7 days at a 
minimum, and ideally through Visit 3 (Day 21-30) or Study Exit/Early Discontinuation. 
Exclusion Criteria: 
1. Patients with active vulvovaginitis or other active infectious causes of cervicitis, vaginitis, or 
vulvitis, based on the results of the thorough clinical assessments and in-clinic microscopic 
assessments performed prior to enrollment  (e.g., candidiasis, Trichomonas vaginalis, 
Chlamydia trachomatis, Neisseria gonorrhoeae, or genital lesions or ulcers consistent with 
human papillomavirus (HPV), Herpes simplex, syphilis, chancroid, etc.). Patients with a 
history of genital herpes or condylomata who have been asymptomatic for at least 6 months 
may be considered for eligibility. 
2. Potential patients who are breastfeeding or, if of child-bearing potential, unwilling to practice 
acceptable means of birth control or abstinence during the study as described above. 
3. Patients with a vaginal, vulvar, or genitourinary condition that, according to the Investigator’s 
judgment, may confound the interpretation of clinical response. 
4. Patients with a history of regional enteritis, ulcerative colitis, or a history of Clostridium 
difficile-associated diarrhea. 
5. Patients with known current drug or alcohol abuse that could impact study compliance.  
6. Patients currently receiving or who have received antifungal or antibacterial therapy (systemic 
or intravaginal) within 14 days of the Screening/Randomization Visit (Visit 1).  
7. Patients who have used any other investigational product within 30 days of the 
Screening/Randomization Visit (Visit 1). 
8. Patients who will undergo evaluation or treatment during the study for abnormal cytology 
and/or findings from high risk HPV testing and/or Pap test finding. 
9. Patients with known sensitivity to clindamycin phosphate or other lincosamides or any of the 
inactive ingredients in the study drug. 
10. Patients with a history of any severe acute or chronic medical or psychiatric condition or 
laboratory abnormality that could increase the risk associated with trial participation or study 
treatment administration or could interfere with the interpretation of trial results and, in the 
judgment of the Investigator, would make the patient inappropriate for entry into the trial. 

Clinical Study Protocol

Daré Bioscience, Inc. 
 
Version/Date: 4.0/14 Aug 2020 
Page 14 of 56 
Test Product, Dose, and Mode of Administration: 
DARE-BV1 (clindamycin phosphate vaginal gel, 2%) will be supplied in tubes with accompanying 
applicators. To dispense the product, the patient will screw the applicator onto the tube and express 
product from the tube into the applicator, up to the stop line on the applicator. One full applicator (5 g) 
of clindamycin phosphate vaginal gel, 2% (100 mg clindamycin) will be applied intravaginally as a 
single dose. 
Reference Therapy, Dose, and Mode of Administration: 
Placebo vaginal gel (HEC Universal Placebo Gel) will be supplied in matching tubes with 
accompanying applicators, as above. One full applicator of placebo vaginal gel (5 g) will be applied 
intravaginally as a single dose.  
Statistical Analyses: 
All statistical processing will be performed using SAS®, Version 9.4, or later. Continuous variables 
will be summarized with number of patients (N), mean, median, standard deviation (SD), minimum 
(Min), and maximum (Max). Categorical variables will be summarized with frequency counts and 
percentages. 
All efficacy analyses will be conducted using a 2-sided test at an alpha level of 0.05. The primary 
efficacy analyses will be conducted on the modified intent-to-treat (mITT) population. Additionally, 
efficacy analyses will be performed on the per-protocol (PP) population and will be considered 
supportive. Safety analyses will be performed on the Safety population. Patients will be analyzed 
according to the treatment to which they were randomized for intent-to-treat (ITT) and mITT analyses, 
regardless of actual treatment received. For all other analysis populations, patients will be analyzed 
according to the treatment they received. 
Populations: 
Intent-to-Treat (ITT): All randomized patients 
Safety: All ITT population patients who applied study drug 
Pharmacokinetic Subset (PKS): All Safety population patients who are enrolled into the PK subset 
Modified Intent-to-Treat (mITT): All Safety population patients except those excluded due to 
demonstrating a positive test result for other concomitant vaginal or cervical infections at baseline 
(e.g., T. vaginalis, N. gonorrhoeae, C. trachomatis, Candida species) or who are determined to have a 
baseline Nugent score of < 7. If the Nugent score at baseline is missing, then the patient is excluded 
from the mITT population.  
Per-Protocol (PP): The PP population will include patients from the mITT population who either 
receive other BV therapy during the study for any reason, or meet the following criteria: 
1. Meet all 4 Amsel’s criteria at screening 
2. Apply study drug within 1 day of randomization 
3. Do not use a prohibited medication prior to the Day 21-30 visit 
4. Attend the Day 21-30 visit  
5. Have no other major protocol violations that impact the primary or secondary endpoints. 
For the mITT and PP populations, if the patient receives other BV therapy for any reason, the patient 
will be included in the analysis as a treatment failure for all visits on or after receipt of the other 
therapy. Patients will be excluded from the PP population if they receive study treatment that was not

the treatment to which they were randomized. A review of the data will be performed prior to locking 
the database and unblinding the study to determine which medications and major protocol violations 
would impact the primary and secondary endpoints and cause a patient to be excluded from the PP 
population. 
Efficacy Analyses: 
All efficacy endpoints will be summarized for each treatment group using descriptive statistics, 
including 95% confidence intervals (within treatment group), as appropriate. 
Primary Efficacy Analyses: 
The primary efficacy analysis of Clinical Cure at Day 21-30 will be analyzed for the mITT population 
with a Cochran-Mantel-Haenszel (CMH) test stratified by study center and race (African-
American/Black versus all others). The method for handling of patients in the mITT analysis without a 
Clinical Cure result at Day 21-30 will be described in the final Statistical Analysis Plan. 
Secondary Efficacy Analyses: 
Hypothesis testing for the secondary efficacy endpoints will be conducted in a sequential manner to 
control the Type 1 error rate, in the order presented below: 
 
Proportion of patients in the mITT population with Bacteriological Cure at the TOC visit 
(Day 21-30).  
 
Proportion of mITT patients with Therapeutic Cure at the TOC visit (Day 21-30).  
 
Proportion of mITT patients with Clinical Cure (defined above) at the Interim Assessment 
visit (Day 7-14). 
 
Proportion of mITT patients with Bacteriological Cure (Nugent score < 4) at the Interim 
Assessment visit (Day 7-14). 
 
Proportion of mITT patients with Therapeutic Cure at the Interim Assessment visit 
(Day 7-14).  
Analysis of the secondary endpoints will follow the same method as the analysis of the primary 
endpoint.  
The PP population will be used to perform sensitivity analyses of the above primary and secondary 
efficacy analyses. Patients in the PP population without a Clinical Cure assessment at the TOC visit 
(Day 21-30) will be excluded from the PP analyses.  
Pharmacokinetic Analysis: 
The following PK parameters will be summarized for the PKS population to assess plasma and vaginal 
clindamycin levels for Days 1-7:  
1. minimum concentration (Cmin)  
2. maximum concentration (Cmax)  
3. area under the curve (AUC0-t), where t is the last time-point with measurable 
concentration)  
4. time to maximum concentration (Tmax)  
5. elimination half-life (t1/2) 
Descriptive summaries of plasma and vaginal clindamycin levels will be presented for each timepoint.

Safety Analyses: 
Descriptions of AEs will include the date of onset, the date the AE ended, the maximum severity of the 
AE, relationship to study drug, seriousness, any action taken, and the outcome. 
All TEAEs occurring during the study will be recorded and classified on the basis of Medical 
Dictionary for Regulatory Activities (MedDRA) terminology. Treatment-emergent AEs are those AEs 
with an onset at the time of, or after the application of study drug. All reported TEAEs will be 
summarized by treatment group, system organ class and preferred term. Adverse events summaries will 
also include severity, relationship to study drug, and seriousness. When summarizing events by 
causality and severity, each patient will be counted only once within a system organ class or a preferred 
term by using the event with the greatest relationship and highest severity within each classification. In 
addition, a list of patients who had a serious adverse event (SAE) or who prematurely discontinued 
from the study due to an AE will be provided. 
Changes from baseline and shifts from baseline will be summarized for safety laboratory results. A 
listing that displays all out-of-range laboratory test results will also be provided.  
Local site reactions will be summarized at each visit. 
Interim Analysis: 
No interim analyses are planned. 
Sample Size Justification: 
The sample size calculations were performed using SAS® version 9.4 for the 2-group chi-square test. It 
is expected that this test will provide approximately the same power as the CMH test stratified by 
analysis center and race. A sample size of 188 DARE-BV1 versus 94 placebo patients will have 90% 
power to detect a statistically significant difference at a significance level of 0.05 (2-tailed) under the 
assumption that the clinical cure rates will be 55% and 30% for DARE-BV1 and placebo, respectively. 
This sample size assumes 35% of randomized patients will not be in the mITT population.

Notes 
If necessary due to persistent symptoms of BV, patients may be offered other BV treatment prior to completion of the study; however, whenever feasible, other BV therapy should 
not be initiated until the patient has completed the final TOC Visit (Visit 3, Day 21-30). If initiated prior to Visit 3, then the patient should remain in the study and return to the 
clinic for the final TOC Visit (Visit 3, Day 21-30). If other treatment is prescribed at Visit 3, then the patient should either be followed by the study doctor (if the patient is 
regularly treated at their clinic), or be referred back to their local health care provider for further follow-up, as appropriate. The choice of other BV therapy is left up to the 
Investigator in collaboration with the patient, based on the current standard of care.  
Any other medications received for treatment of BV should be recorded as concomitant medications. 
1 Patients who are discontinued early from the study will be contacted by phone between study Day 21-30 to assess BV symptoms, adverse events and concomitant medications.  
2 For medical, gynecological, contraceptive, and relevant sexual history, the recorded information will include: acute and chronic history of medical and gynecological conditions 
(including history of BV), smoking, illicit drug and alcohol use history, menstrual cycle history (start date of last menstrual cycle and expected timing of next menses will be 
collected), medically relevant sexual history including history of sexually-transmitted infections (STIs), current sexual activity, previous/current contraceptive use, and pregnancy 
history. 
3 Pregnancy testing via urine human chorionic gonadotropin (hCG) testing will be performed for each patient, unless patient is of non-child-bearing potential as defined within 
Inclusion Criterion #5, at each visit (serum hCG testing will be done only if deemed necessary by the Investigator). 
4 At all visits an in-clinic urine dipstick will be performed. At Visit 1, Visit 3, and the Early Discontinuation visit a central laboratory urinalysis will also be performed. 
5 A complete physical examination should be performed at Visit 1; at Visit 3 and at the Early Discontinuation visit (if applicable), a directed physical examination should be 
performed in accordance with the Investigator’s judgment. Rectal and breast examinations are not required for the complete or directed physical examinations.

6 Pelvic examination will include a vaginal wall inspection as well as an examination of the cervix and will include assessment and appropriate reporting of any abnormalities, and 
confirmation that all findings are consistent with BV, versus Candidiasis or other causes of the patient’s vaginal signs or symptoms. 
7 A review of patient-reported and Investigator-assessed local site reactions will occur at each visit after randomization and treatment. A baseline assessment will be recorded for 
all subjects during Visit 1 Screening assessments. 
8 The color, odor, and consistency of vaginal discharge are to be assessed as part of the assessment of the Amsel Criteria, and the presence of vulvovaginal itching and irritation are 
to be assessed as part of the assessment of Local Site Reactions.   
9 The microscopic yeast assessment may be done on the same sample obtained for the 10% KOH whiff test. A swab of the vaginal pool should be utilized for both assessments.  
10 Diagnostic assessments for Candida spp, C. trachomatis, N. gonorrhoeae, or T. vaginalis may be repeated after baseline if changes in the patient’s clinical condition warrant re-
testing. Full instructions for the collection of all samples, including the slides for Nugent scoring, will be provided in the laboratory procedures manual.  
11 Perform compliance assessment by weighing both the dispensed and returned tubes and recording the weights in the eCRF.

INTRODUCTION 
5.1 
STUDY RATIONALE AND BACKGROUND 
Bacterial vaginosis (BV) is the most common vaginal infection in postmenarchal females of childbearing 
age. It is a condition in which there is excess growth of certain types of bacteria within the vagina. Recent 
descriptions have identified in particular the overgrowth of Gardnerella vaginalis and Atopobium 
vaginae. This overgrowth affects the normal balance of bacteria within the vagina and can lead to 
symptoms that include: 
 
A thin white or gray vaginal discharge 
 
Pain, itching, or burning in the vagina

The causes of BV are not fully understood. It is known that BV is more common in sexually active 
women, but it is not known how sex contributes to BV (Hay, 2014; Center for Disease Control, 2017). 
In addition to its symptoms, there is some evidence that BV may contribute to pelvic inflammatory 
disease, preterm birth, and higher risk of acquisition of sexually transmitted infections (Center for Disease 
Control, 2017; Sobel & Sobel, 2015; Taylor, 2013). 
Currently, in the United States (U.S.), oral and intravaginal metronidazole, intravaginal clindamycin, oral 
tinidazole, and oral secnidazole are available for the treatment of BV. 
DARE-BV1 is a thermosetting bioadhesive intravaginal gel formulated with 2% clindamycin phosphate 
designed to release the active ingredient for an extended period of time (Mondal, 2011). The extended 
period of time is approximately 7 days, based on in vitro data, and will be better defined in this study with 
the pharmacokinetic (PK) subset. Research has shown that effective drug delivery is essential to 
optimizing drug therapy for BV. Because of its chemical composition, DARE-BV1 is designed as non-
toxic and should not compromise condoms or diaphragms. 
DARE-BV1 is a viscous solution that undergoes solution to gel (sol-to-gel) transition at body 
temperature. This property allows the product to remain at the site of vaginal infection. By the process of 
“reverse thermal gelation,” the viscosity of the base matrix increases from room temperature when 
exposed to body temperature. 
Clindamycin has been found effective against organisms usually associated with BV such as Bacteroides 
species (spp.), Peptococcus spp., Gardnerella vaginalis, Mobiluncus spp., and Mycoplasma hominis. 
Clindamycin can be classified as a time-dependent antibiotic for which maximizing the exposure time and 
the amount of drug is recommended to improve efficacy. Topical application, safety, and efficacy of 
vaginally delivered clindamycin phosphate have been widely demonstrated in published literature 
(e.g., Donders, 2014). 
DARE-BV1, formulated with clindamycin, is designed to produce a prolonged duration of exposure to 
clindamycin at the site of infection. 
DARE-BV1 has been evaluated in a fertility and early embryonic development to implantation study in 
rats (Segment 1 reproductive toxicology).  It has also been tested in embryo-fetal development toxicity 
and toxicokinetic studies in rats and rabbits (Segment 2 reproductive toxicology).  No adverse outcomes 
were noted in these studies.  Based on these findings, the administration of DARE-BV1 to pregnant

women is justified.  Therefore, patients who are known to be pregnant at the time of screening (and who 
satisfy all entry criteria) will be allowed to enroll in the study. 
5.2 
RISK/BENEFIT ASSESSMENT 
5.2.1 
Known Potential Risks/Benefits 
DARE-BV1 clindamycin phosphate vaginal gel, 2%, is contraindicated in patients with a prior history of 
hypersensitivity to clindamycin or other lincosamides or other ingredients of the formulation. 
In currently marketed clindamycin phosphate vaginal cream 2% (Clindesse®), the most common adverse 
reactions, reported in ≥2% of patients and at a higher rate in the active treatment group than in the placebo 
group, were vaginosis fungal (14%), headache (7%), back pain (5%), constipation (2%), and urinary tract 
infection (2%) (Perrigo Specialty Pharmaceuticals, 2014). 
Many oral antibiotics, including clindamycin, may cause overgrowth of dangerous bacteria in the large 
intestine (e.g. Clostridium difficile). This may cause mild diarrhea, or it may cause a life-threatening 
condition called colitis (inflammation of the large intestine). Clindamycin is more likely to cause this type 
of infection than many other antibiotics. Patients with Crohn’s disease (regional enteritis), ulcerative 
colitis, or C. difficile-related diarrhea are not eligible for the study.  Patients with other types of chronic 
enteritis or colitis should be discussed with the Medical Monitor prior to randomization.        
Other known side effects of oral clindamycin treatment are listed below. This information is not based on 
treatment with 2% clindamycin vaginal gel, which would be expected to result in significantly lower 
systemic blood levels than those obtained with oral formulations.

Nausea 
 
Vomiting 
 
Unpleasant or metallic taste in the mouth 
 
Joint pain 


Potential benefits of DARE-BV1 in treatment of BV include its simplicity of use (a single application), its 
thermoreversible properties that should keep the product from leaking out and increase residence time, the 
well-established effectiveness of clindamycin in treating BV, and the infrequency of serious side effects 
associated with clindamycin use.

5.2.2 
Assessment of Potential Risks and Benefits 
Potential risks that may be associated with use of DARE-BV1 have been minimized in this study by the 
following: 
 
Establishing eligibility criteria that exclude patients with clinically significant conditions that 
would preclude DARE-BV1 use; 
 
Selecting Investigators with the proper level of training and experience in assessing and treating 
BV; 
 
Ensuring adequate monitoring is performed to identify any safety issues associated with the study 
procedure and patients; and 
 
Regularly reviewing reported serious adverse event (SAEs) and adverse events (AEs) throughout 
the study and taking appropriate medical measures to resolve the AEs. 
The expected risk/benefit profile for DARE-BV1 is sufficient to perform this Phase 3 clinical study.

STUDY DESIGN 
7.1 
OVERALL DESIGN 
This is a multicenter, randomized, double-blind, placebo-controlled study of DARE-BV1 clindamycin 
phosphate vaginal gel, 2% (daily [QD] × 1 day) compared to placebo vaginal gel (hydroxyethylcellulose 
[HEC] Universal Placebo Gel) (QD × 1 day) for the treatment of BV. Patients will be evaluated at 3 time 
points: a Day 1 Screening/Randomization visit, a Day 7-14 Interim Assessment visit, and a Day21-30 
TOC visit (or a Day 21-30 Safety Follow-up phone call visit for patients who are prematurely 
discontinued). The total study duration will be up to approximately 1 month for a patient. 
At the Screening/Randomization Visit (Day 1), past medical and obstetrical/gynecological/menstrual 
history, contraception and medically relevant sexual history, and lifetime BV history and number of 
episodes of BV in the preceding 12 months (along with treatment given) will be collected/evaluated. 
Signs and symptoms of BV will be evaluated, including color, odor and consistency of vaginal discharge, 
plus vulvovaginal itching and irritation will be assessed.  
Additionally, the following samples/tests will be collected and performed: saline wet mount to assess clue 
cell percentage and other pertinent findings (e.g., trichomonads, white blood cells, other cellular and 
microbial elements), 10% KOH whiff test and KOH wet mount for yeast assessment; vaginal culture for 
Candida species; vaginal pH; slide preparation for centralized Gram stain for Nugent scoring, urine 
pregnancy test, NAATs for Chlamydia trachomatis and Neisseria gonorrhoeae, OSOM® test for 
Trichomonas vaginalis, blood sample for chemistry and hematology and urinalysis. 
A major goal of the screening process is to confirm the presence of BV and to rule out the presence of 
other infectious and non-infectious causes of vulvovaginitis. Careful attention must therefore be paid to 
both the clinical assessment of the patient and to microscopic assessments (saline and KOH wet mount). 
However,  the medical literature suggests that clinical and microscopic assessments are less than optimal 
at identifying patients with candidiasis (Schwebke, 2020; Lowe, 2009); therefore, a vaginal culture for 
Candida species will be obtained at baseline on each randomized patient, and used to determine if the 
patient will be included in the modified intent-to-treat (mITT) population. The NAAT testing for 
N. gonorrhea and C. trachomatis will be obtained for similar reasons, and rapid testing for T. vaginalis 
will be performed onsite to rule out Trichomonas prior to randomization.  
In the event that there is any ambiguity in the patient’s signs, symptoms, or microscopic assessments 
suggesting that the patient may have a mixed infection, then randomization and treatment should be 
delayed until the results of the yeast culture and/or NAATs are available (assuming the patient is able and 
willing to have treatment delayed for several more days).  If the yeast culture (or NAAT) result is positive 

Clinical Study Protocol 
DARE-BV1-001 
Daré Bioscience, Inc. 
 
Version/Date: 4.0/14 Aug 2020 
Page 28 of 56 
(or if it is not feasible to delay treatment), then the patient should be screen-failed.      
If, however, the patient’s screening assessments support the diagnosis of BV only and the patient is 
randomized, but it is later learned that the Candida culture was positive at screening, the clinician should 
assess whether antifungal therapy is clinically warranted, or if the culture represents a subclinical 
condition that does not require medical treatment.  An AE should be captured in the eCRF only if the 
patient requires treatment for signs/symptoms consistent with a yeast infection, i.e., a positive culture by 
itself does not constitute an AE.   
Patients with positive NAAT results at screening for C. trachomatis or N. gonorrheae should be treated as 
indicated per the investigator’s judgment, and an AE captured in the eCRF.  In such cases, the AE eCRF 
question “Did this adverse event begin prior to using the study medication?” should be answered “Yes” to 
indicate that the AE onset was prior to dosing.    
Patients should not be menstruating at the Screening/Randomization Visit, nor expected to begin 
menstruating during the 7 days after study drug administration; therefore, the optimal timing for the 
Day 1 visit should be carefully evaluated during pre-screening. If the patient is found to be menstruating 
at the time of the initial Screening/Randomization visit or is due to start menstruating within 1 week of 
the visit, then randomization should be delayed. For this reason (and others), split screening visits are 
allowed. Ideally the patient will return to the clinic as soon as possible after the end of her menses for 
completion of all assessments and randomization; however, a 14-day window is provided to 
accommodate this and other circumstances that could require a delay in randomization. Section 10.1.1 
provides additional information regarding the assessments that must be completed on the day of 
randomization (Day 1), regardless of the reason for the delay.  
At Visit 1 patients will also be provided with instructions for using a daily electronic diary (eDiary). The 
patient eDiary will be utilized to collect information regarding study drug administration, symptoms 
related to BV, relevant AEs and other pertinent information. Site staff will review the patient’s eDiary 
responses with the patient at each study visit to ensure that all relevant information is documented in the 
electronic case report form (eCRF) (such as medication use and AEs since the previous visit). 
Eligible patients will be randomly assigned via Interactive Response Technology (IRT) to one of the 
following treatment groups (2:1): clindamycin phosphate vaginal gel, 2% (DARE-BV1; 1 dose is 5 g 
gel = 100 mg clindamycin) QD × 1 day, or placebo vaginal gel (Universal HEC Placebo Gel), 5 g, 
QD × 1 day. Study drug will be applied intravaginally within 1 day of randomization.  
The patients will return to clinic for Visit 2 on Day 7-14 for the Interim Assessment visit. A third and 
final visit will be conducted at Day 21-30 for Test of Cure (TOC). Similar to the requirement at 
randomization, patients should not be actively menstruating on the day of the Interim or TOC Visit, 
although the TOC Visit should take priority, if scheduling around menses is challenging. At both the 
Visit 2 (Day 7-14) and Visit 3 (Day 21-30) visits, the Investigator will perform gynecological 
examinations and collect specimens for the following tests: saline wet mount to assess clue cell 
percentage, 10% KOH whiff test and wet mount microscopic yeast assessment, vaginal pH, preparation of 
slides for the centralized Gram stain for Nugent Scoring, urinalysis, and urine pregnancy test. 
Additionally, the signs and symptoms of BV including color, odor, and consistency of vaginal discharge, 
plus vulvovaginal itching and irritation will be evaluated at each visit. Post-treatment blood chemistry and 
hematology assessments will be obtained at the TOC Visit (Visit 3, Day 21-30). If clinical symptoms 
(supported by microscopic findings) indicate active vulvovaginal candidiasis at Visit 2 or Visit 3, a 
vaginal yeast culture should be obtained. Repeat diagnostic testing for N. gonorrhoeae, C. trachomatis or 
T. vaginalis may also be obtained at any time if clinically warranted to determine the etiology of a change 
or worsening in vaginal discharge or other signs or symptoms. Any clinically significant conditions 
arising after randomization should be recorded as AEs.  

Clinical Study Protocol

Page 29 of 56 
Approximately 20 patients at selected sites (2-4 sites are anticipated) will participate in a PK study. The 
patients in this subset will apply the study drug at the study clinic during Visit 1 and will have blood 
draws for plasma clindamycin assessment taken at 0 hours (pre-dose) and then at 2, 4, 6, and 8 hours 
(±15 minutes) post-dose, as well as at 24, 48, 72, 96, 120, and 144 hours (±2 hours) post-dose (Days 2-7). 
In addition, samples for vaginal clindamycin concentrations will be collected on Days 1--7 (with the 
Day 1 sampling schedule starting pre-dose; no post-dose vaginal clindamycin samples will be collected 
on Day 1). For these patients, the assessments for the Interim Assessment (Day 7-14) visit may be done 
on the same day as the Day 7 PK draw. 
Assessment and documentation of AEs and concomitant medications will occur at each visit. A review of 
patient-reported and Investigator-assessed local site reactions will occur at each visit after randomization 
and treatment. Patients’ daily eDiary entries will be reviewed at each visit. 
If necessary due to persistent symptoms of BV, patients may be offered other BV treatment prior to 
completion of the study; however, whenever feasible, other therapy should not be initiated until the 
patient has completed the final TOC Visit (Visit 3, Day 21-30). If initiated prior to Visit 3, then the 
patient should remain in the study and return to the clinic for the final TOC Visit (Visit 3, Day 21-30). If 
other BV treatment is prescribed at Visit 3, then the patient should either be followed by the study doctor 
(if the patient is regularly treated at their clinic), or referred back to their local health care provider for 
further follow-up, as appropriate. The choice of other BV therapy is left up to the Investigator in 
collaboration with the patient, based on the current standard of care. Any other medications received for 
treatment of BV should be recorded as concomitant medications. 
The goal is for all patients to complete the study, regardless of whether additional BV treatment (or other 
antibacterial/antifungal therapy) is provided prior to completion of the final TOC visit/Visit 3. Patients 
who discontinue prematurely from the study for any reason will receive a Safety Follow-up phone 
call between Study Days 21-30 to assess the status of BV symptoms, AEs, and medication usage. 
7.2 
SCIENTIFIC RATIONALE FOR STUDY DESIGN 
A double-bind, placebo-controlled, randomized design is appropriate for investigating the efficacy, safety 
and acceptability of a vaginal antibiotic treatment for BV because this study design has been well-
established in the published literature for evaluating BV treatment in a Phase 3 study. The study design is 
also consistent with the current U.S. Food and Drug Administration (FDA) draft guidance entitled 
“Bacterial Vaginosis: Developing Drugs for Treatment,” dated August 2019. 
7.3 
JUSTIFICATION FOR DOSE 
Use of one full applicator (5 g) of clindamycin phosphate vaginal gel, 2% (100 mg clindamycin) is 
justified based on published data for existing marketed vaginal clindamycin treatments for BV.  
7.4 
END OF STUDY DEFINITION 
The end of the study is defined as completion of the last visit or procedure shown in the Schedule of 
Assessments in the trial globally. 
7.5 
STUDY DURATION 
The study duration for each patient will be up to approximately 1 month: Visit 1 (Day 1) 
Screening/Randomization Visit including treatment; Visit 2 (Day 7-14) for interim assessment of efficacy

parameters and safety; and either the final Visit 3 (Day 21-30) assessment of efficacy and safety, or the 
Follow-up Safety Phone Visit (Day 21-30) for patients who discontinue prematurely from the study.  
8 
STUDY POPULATION 
Patients with a clinical diagnosis of BV at the Screening/Randomization Visit who meet the following 
eligibility criteria may participate in the study. 
8.1 
INCLUSION CRITERIA 
1. Patients must provide written informed consent prior to any study-related procedures being 
performed. Patients from 12 through 17 years old may participate where permitted by applicable 
local regulations and Institutional Review Board (IRB) approval and with appropriate 
documentation of consent from the parent(s)/guardian(s) and assent from the patient. 
2. Patients must have a clinical diagnosis of BV, defined as having all of the following: 
a. Off-white (milky or gray), thin, homogeneous discharge with minimal or absent pruritus 
and inflammation of the vulva and vagina 
b. The presence of clue cells > 20% of the total epithelial cells on microscopic examination 
of the saline wet mount 
c. Vaginal secretion pH of > 4.5 
d. A fishy odor of the vaginal discharge with the addition of a drop of 10% KOH (i.e., a 
positive whiff test) 
3. Patients must be females ≥ 12 years of age with no known medical conditions that, in the 
Investigator’s opinion, may interfere with study participation. 
4. Patients must agree to abstain from sexual intercourse and/or sexual activity throughout the first 
7 days following treatment. Non-pregnant patients must also agree to use adequate birth control 
(see Inclusion Criterion #5) should they later engage in heterosexual intercourse through the 
final study visit (Visit 3, Day 21-30).  
5. This trial will enroll pregnant women; however, non-pregnant patients of childbearing potential 
should use adequate birth control after Day 7 if engaging in heterosexual intercourse, and should 
not plan on becoming pregnant for the duration of the study. Acceptable forms of birth control 
include oral contraceptives (“the pill”), intrauterine devices (IUDs), contraceptive implants under 
the skin, patches or injections, non-polyurethane condoms (e.g., latex, polyisoprene) with or 
without spermicide. Patients in same sex relationships, or monogamous relationships with 
vasectomized males, may also participate. Abstinence may also be acceptable, per the 
Investigator’s judgment. Oral or transdermal hormonal contraceptives must be in use for 1 full 
cycle (e.g., 4 to 8 weeks) prior to study drug application. Injectable or implanted contraceptives 
(e.g., Depo-Provera, Nexplanon, or hormonal IUD) must have been injected/inserted at least 
7 days prior to study drug application.  
Patients who are not of childbearing potential will not need a urine pregnancy test prior to 
randomization or at subsequent visits.  The patient is considered to be of non-child bearing 
potential if one of the following is satisfied:  
a. Postmenopausal for at least 1 year prior to the Screening/Randomization Visit (Visit 1) 
(defined as amenorrheic for more than 1 continuous year), or 
b. Surgically sterile (defined as bilateral tubal ligation, bilateral oophorectomy, or

hysterectomy) at least 6 months before first dose, or 
c. Non-surgical permanent sterilization procedure performed at least 3 months prior to study 
drug application. 
Patients must be willing to refrain from the use of all intra-vaginal products (e.g., douches, 
feminine deodorant sprays, condoms, spermicides, vaginal moisturizers or lubricants, tampons, 
vaginal birth control rings [e.g., NuvaRing®], and diaphragms) through the first 7 days at a 
minimum, and ideally through Visit 3 (Day 21-30) or Study Exit/Early Discontinuation. 
8.2 
EXCLUSION CRITERIA 
1. Patients with active vulvovaginitis or other active infectious causes of cervicitis, vaginitis, or 
vulvitis, based on the results of the thorough clinical assessments and in-clinic microscopic 
assessments performed prior to enrollment  (e.g., candidiasis, Trichomonas vaginalis, Chlamydia 
trachomatis, Neisseria gonorrhoeae, or genital lesions or ulcers consistent with human 
papillomavirus (HPV), Herpes simplex, syphilis, chancroid, etc.). Patients with a history of 
genital herpes or condylomata who have been asymptomatic for at least 6 months may be 
considered for eligibility. 
2. Potential patients who are breastfeeding or, if of child-bearing potential, unwilling to practice 
acceptable means of birth control or abstinence during the study as described above. 
3. Patients with a vaginal, vulvar, or genitourinary condition that, according to the Investigator’s 
judgment, may confound the interpretation of clinical response. 
4. Patients with a history of regional enteritis, ulcerative colitis, or a history of C. difficile-associated 
diarrhea. 
5. Patients with known current drug or alcohol abuse that could impact study compliance.  
6. Patients currently receiving or who have received antifungal or antibacterial therapy (systemic or 
intravaginal) within 14 days of the Screening/Randomization Visit (Visit 1). 
7. Patients who have used any other investigational product within 30 days of the 
Screening/Randomization Visit (Visit 1). 
8. Patients who will undergo evaluation or treatment during the study for abnormal cytology and/or 
findings from high risk HPV testing and/or Pap test finding. 
9. Patients with known sensitivity to clindamycin phosphate or other lincosamides or any of the 
inactive ingredients in the study drug. 
10. Patients with a history of any severe acute or chronic medical or psychiatric condition or 
laboratory abnormality that could increase the risk associated with trial participation or study 
treatment administration or could interfere with the interpretation of trial results and, in the 
judgment of the Investigator, would make the patient inappropriate for entry into the trial. 
8.3 
SCREEN FAILURES 
Screen failures are defined as patients who consent to participate in the clinical trial but are not 
randomized to receive treatment. Screen failures may be re-screened in cases where the unmet selection 
criteria have been resolved after previous screen failure. A new Informed Consent Form (ICF) will be 
needed for re-screened patients if more than 30 days have passed since informed consent was obtained. 
Re-screened patients who are re-screened past the 30-day window and are re-consented will be assigned a 
new patient number. Randomized patients prematurely withdrawn from the study will not be replaced.

MEASURES TO MINIMIZE BIAS: RANDOMIZATION AND BLINDING 
9.3.1 
Randomization 
Randomization will occur after a patient’s eligibility has been confirmed. Patients will be assigned a 
unique patient identification number by the site at screening. Following completion of the screening 
procedures, eligible patients will be randomized in a blinded manner via the validated, access controlled, 
IRT system. Stratification factors in the randomization are: PK subset (Yes/No), site, and race (African-
American/Black versus all others). Patients will be randomized to 1 of 2 treatment groups (DARE-BV1 
[clindamycin phosphate vaginal gel, 2%] or placebo vaginal gel) in a 2:1 ratio, with approximately 
188 patients be randomized to DARE-BV1, and 94 patients randomized to placebo vaginal gel.  
Randomization will be requested by adequately trained and delegated site staff with appropriate user 
access to the IRT system. Unique patient randomization numbers and treatment allocations will be 
provided within the IRT system and will be generated from the randomization scheme. A randomization 
number will be automatically provided by the IRT system and confirmed by email, ensuring concealment 
of treatment allocation.  
9.3.2 
Blinding 
This is a double-blind study. The Principal Investigator and other site staff will be blinded to study 
treatment throughout the conduct of the study. Treatment randomization information will be kept 
confidential and will not be released to the blinded Investigator or blinded Investigator site personnel until 
the study database has been locked or the Investigator requests unblinding for safety reasons.  
At the initiation of the study, the site will be instructed on procedures for breaking the blind for safety 
reasons. The study blind should be maintained whenever possible to avoid bias. Active study drug and 
placebo reference therapy will be packaged in matching tubes with accompanying applicators. 
If the treatment assignment must be revealed for the safety of the patient or to treat an AE, the 
Investigator should contact the Medical Monitor or designee. A decision to break the blind should be 
reached by the Medical Monitor or designee and the Investigator.  
The Investigator or designee may break the blind independent of the Medical Monitor only if it is 
considered an emergency by the Investigator. If this occurs, the Medical Monitor and the Sponsor must be 
notified within 24 hours of breaking the blind.  
The event requiring breaking the blind must be documented and reported appropriately, including the date 
the blind was broken.  
9.4 
STUDY INTERVENTION COMPLIANCE 
Participants will return their study drug tube and applicator following use.  Study drug compliance will be 
verified through confirmation of the weight of the study drug tube prior to dispensation and upon return to 
the study site.  Additional dosing information will be captured in real-time via patient reported eDiary 

Clinical Study Protocol 
DARE-BV1-001

Page 34 of 56 
entries to ensure application procedures were properly followed. Finally, compliance information will be 
recorded for each patient on a study-specific drug accountability log. 
Instances of significant over- or under-dosing are considered protocol deviations but will not be 
automatically recorded as AEs. Any undesirable medical occurrence resulting from significant over- or 
under-dosing is an AE and should be recorded and reported on the AE eCRF. The Investigator should record 
the event in the source document and should monitor the subject. 
9.5 
ELECTRONIC DIARY 
Patients will be instructed on how to use their daily eDiary at Visit 1. Site staff will review eDiary entries 
with patients at each study visit and ensure that any relevant information pertaining to new medications or 
AEs has been appropriately captured in the eCRF. 
9.6 
CONCOMITANT THERAPY 
Concomitant medications include any medication or health product (any prescription medications or over-
the-counter preparations) taken from the time the patient signs the informed consent documents until 
study exit and must be reported appropriately on the eCRF. Information on prior medications taken within 
30 days of consent should be collected (including supplements and herbal remedies in addition to 
prescription and over-the-counter medications). 
Recording of all concomitant treatments will occur on the patient’s source and eCRF, including the name 
of the drug, dose, start and stop dates, and reason for use, from the time the ICF is signed through 
completion or discontinuation from the trial. Any other investigational product must have been stopped at 
least 30 days before the start of screening for this trial. Other medications for the treatment of inter-
current medical conditions will be permitted and recorded as detailed above unless identified as 
prohibited medications.  
Patients should not have received antifungal or antibacterial therapy (systemic or intravaginal) during the 
14 days prior to the Screening/Randomization Visit (Visit 1). Patients on suppressive antiviral therapy for 
herpes simplex infections are considered eligible for the study provided they have remained 
asymptomatic for at least 6 months prior to screening (as per Exclusion Criterion #1) and antiviral therapy 
is expected to continue in a stable fashion for the duration of the study. Patients receiving antiviral 
therapy for other indications at the time of screening should be assessed on a case-by-case basis and 
discussed with the Medical Monitor prior to randomization. Oral probiotics are permitted, provided usage 
has been stable for at least 1 month prior to randomization and is intended to remain stable during the 
patient’s study participation.  
Patients enrolled and treated in this study who have lack of relief of BV symptoms at or prior to Visit 3 
and are treated with other BV therapy should not be discontinued from the study. The same is generally 
true for patients requiring any other antimicrobial therapy during their study participation. Patients who 
satisfy all eligibility criteria based on clinical and microscopic assessments at screening, but then, after 
randomization and dosing, are discovered to be positive for Chlamydia (CT), gonorrhea (NG), or Candida 
based on their screening NAATs or Candida culture, should be encouraged to complete the study; i.e., 
they should not be discontinued solely due to positive screening laboratory results--unless there are 
reasons why it is not in the patient’s best interest to continue in the study.  The goal is for all patients to 
complete the study whenever feasible and appropriate; therefore, any patient requiring antifungal, 
antibacterial (whether for BV or an unrelated indication), or antiviral therapy should be assessed on a 
case-by-case basis, and if in doubt, discussed with the Medical Monitor, to determine if/when it is not 
appropriate for the patient to continue in the study.

9.7 
PATIENT DISCONTINUATION/WITHDRAWAL FROM THE STUDY 
Each patient will be informed of her right to withdraw from the study at any time and for any reason. A 
patient may be discontinued from the study at any time if the patient, the Investigator, or the Sponsor feels 
that it is not in the patient’s best interest to continue in the study.  
Patients who sign the ICF and agree to participate in the study, but do not meet eligibility criteria, will be 
considered screen failures.  
Following enrollment, patients may be discontinued from the study for the following reasons:  
 
Lack of compliance (i.e., failure to follow protocol requirements that is judged severe enough by 
the Investigator to significantly affect study outcomes) 
 
Any AE or intercurrent illness that would jeopardize the patient’s health or the interpretation of 
the results of the study 
 
Lost to follow-up 
 
Patient withdrawal of consent  
 
Treatment failure 
 
Retrospective discovery of an entry criterion violation 
 
Pre-existing condition or abnormality, including abnormal laboratory or microbiological result 
obtained at screening 
 
Other (e.g., sponsor decision, pregnancy during the study, logistical issues related to Covid-19, 
etc.) 
Prior to discontinuing a patient from the study, the site should contact Daré or designee. The reason for 
discontinuation must be recorded on the appropriate section of the patient’s eCRF and Early 
Discontinuation procedures should be performed. 
9.8 
LOST TO FOLLOW-UP 
A patient cannot be considered withdrawn due to becoming lost to follow-up (LTFU) until the research 
site performs and documents at least 3 attempts to contact her. Documentation must include at least 
1 letter sent via a method that allows a “return receipt,” e.g., certified mail, to be requested with 
instructions provided to the patient to contact the research site. Every reasonable effort must be made to 
follow up with patients who discontinue with study drug-related AEs in order to determine the final 
outcome. 
Patients designated as LTFU who later resume contact with the site should be requested to come in for an 
unscheduled visit to complete early discontinuation procedures. Documentation should include the period 
of time they were out of contact with the site (after last contact). If the Investigator anticipates future 
problems with follow up, then the patient should be withdrawn from the study. 
10 
STUDY ASSESSMENTS AND PROCEDURES 
10.1 
STUDY VISITS 
The study will include 3 scheduled in-clinic visits for all patients, plus a follow-up phone call for patients 
who discontinue prematurely: 
 
Visit 1: Screening/Randomization for all patients 

Clinical Study Protocol 
DARE-BV1-001

Version/Date: 4.0/14 Aug 2020 
Page 36 of 56 
 
Visit 2 (Days 7-14): Interim Assessment for all patients 
 
Visit 3 (Days 21-30): TOC for all patients 
 
Safety Follow-up Phone Visit (Days 21-30) for all prematurely discontinued patients 
For patients in the PK subset only, there will be additional blood draws and vaginal clindamycin 
concentration collections at the Screening/Randomization Visit (Day 1) as well as 5 additional visits 
between Visit 1 and Visit 2 (Visits PK1-PK5 on Days 2 through 6). The assessments for the Interim 
Assessment Visit (Day 7-14) may be done on the same day as the Day 7 PK draw. 
Refer to the Schedule of Assessments for the study (Table 1) and for the PK subset (Table 2) as well as 
the by-visit descriptions below for additional details. 
10.1.1 
Visit 1: (Day 1) Screening/Randomization  
All Visit 1 (Screening/Randomization) procedures should be completed on the same day when feasible. If 
it is not feasible to complete all assessments on the same day, or if the patient’s menstrual cycle requires a 
delay in randomization, then confirmation of eligibility must be repeated at the time of randomization. 
The specific assessments that must be performed on the day of randomization are identified below; the 
Investigator may use clinical judgment to decide whether other assessments should also be repeated. If 
randomization does not occur on same day as the initial screening visit, the patient should return no later 
than 14 days from start of screening (i.e., the signing of the ICF) for randomization. 
During Visit 1, the following procedures should be performed. All assessments must be completed prior 
to randomization; however, if randomization must be delayed and a split screening visit is utilized, then 
the asterisked and italicized assessments below must then be completed (or repeated) on the day of 
randomization.

10.1.6 
Safety Follow-up Phone Call 
Patients who discontinue early from the study will receive a follow-up phone call from the site staff 
between Study Day 21-30. Patients will be asked questions regarding AEs, concomitant medications and 
the status of their BV symptoms. 
10.1.7 
Unscheduled Visits 
Unscheduled visits are allowed at the discretion of the Investigator for safety assessments or 
administrative reasons. During unscheduled visits, the Investigator will perform any study assessments or 
other safety assessments as necessary to provide appropriate treatment.  
10.2 
EFFICACY ASSESSMENTS 
The primary efficacy endpoint (Clinical Cure at the TOC visit [Day 21-30]) is the resolution of the 
following 3 BV signs included in Amsel’s criteria (Amsel, 1983): abnormal vaginal discharge associated 
with BV as determined by the Investigator, positive KOH whiff test, and the presence of clue cells at 
>20% of the total epithelial cells on microscopic examination of the saline wet mount. 

Clinical Study Protocol 
DARE-BV1-001 
Daré Bioscience, Inc. 
 
Version/Date: 4.0/14 Aug 2020 
Page 40 of 56 
The supportive secondary efficacy endpoints are the Bacteriological Cure and the Therapeutic Cure. The 
bacteriological cure is defined as Nugent’s score <4 (via Gram stain performed by a central laboratory). A 
Nugent score ≥4 is considered abnormal and represents an imbalance in vaginal flora that permits BV to 
manifest (Nugent, 1991). Patients who are responders are expected to achieve a normal Nugent score 
(i.e., 0 through 3) following treatment. 
Therapeutic cure is defined as having achieved both Clinical Cure (i.e., resolution of abnormal discharge 
associated with BV, negative whiff test and <20% clue cells on wet mount) and Bacteriological Cure 
(i.e., Nugent score of <4). 
10.3 
SAFETY AND OTHER ASSESSMENTS 
10.3.1 
Medical, Gynecological, Contraceptive, and Relevant Sexual History 
A complete medical, gynecological, contraceptive, and relevant sexual history will be collected at Visit 1, 
including prior and concomitant illnesses. The recorded information will include: acute and chronic 
history of medical and gynecological conditions (including history of BV), smoking, illicit drug and 
alcohol use history, menstrual cycle history (start date of last menstrual cycle and expected timing of next 
menses will be collected), medically relevant sexual history including history of sexually-transmitted 
infections (STIs), current sexual activity, previous/current contraceptive use, and pregnancy history. 
10.3.2 
Demographics 
The date of birth, race, ethnicity, and sex of the patient are to be recorded at Visit 1. 
10.3.3 
Vital Signs, Height, and Weight 
Vital sign measurements will be taken at each visit and include sitting (after 5 to 10 minutes in this 
position) measurements of diastolic and systolic blood pressure, heart rate, and oral temperature per 
standard of care. Height and weight will be measured only at Visit 1. 
10.3.4 
Urine Pregnancy Test 
Pregnancy testing via urine human chorionic gonadotropin (hCG) testing will be performed for each 
patient, unless the patient is not of childbearing potential as defined in Inclusion Criterion #5, at each visit 
(serum hCG testing will be done only if deemed necessary by the Investigator). Additional pregnancy 
testing may also be performed if there is any suspicion or clinical concern that a woman might be 
pregnant at any time during the study. 
10.3.5 
Urinalysis 
Onsite dipstick urinalysis will be performed at Visit 1 (Screening), Visit 2 (Interim Assessment), Visit 3 
(TOC), and at the Early Discontinuation Visit as specified in the Schedule of Assessments (Table 1 and 
Table 2 [for PK subset]). In addition, a full urinalysis will be performed by the central laboratory for 
Visit 1 (Screening), Visit 3 (TOC), and at the Early Discontinuation visit. If an abnormal laboratory result 
from the screening assessment is judged by the Investigator as being clinically significant but not 
exclusionary, it should be reported as medical history. If clinical symptoms or urinalysis results at 
screening suggest that the patient may have a urinary tract infection that could require antibiotic therapy, 
then the patient should be screen failed and referred for further evaluation.

10.3.6 
Hematology/Chemistry 
Samples for hematology and clinical chemistry assessments will be collected at Visit 1 (Screening), 
Visit 3 (TOC), and the Early Discontinuation visit as specified in the Schedule of Assessments (Table 1 
and Table 2 [for PK subset]). If an abnormal laboratory result from the screening assessment is judged by 
the Investigator to be clinically significant, it should be reported as medical history.  
10.3.7 
Physical Examination 
A complete physical examination should be performed at Visit 1. A directed physical exam should be 
performed at Visit 3 and at the Early Discontinuation visit (if applicable), in accordance with the 
Investigator’s judgment. Clinically significant physical examination findings should be reported as 
medical history or AEs, as appropriate. Rectal and breast examinations are not required for either the 
complete or directed physical exams. 
10.3.8 
Pelvic Examination 
A pelvic examination will be performed at each visit and will include a vaginal wall inspection as well as 
an examination of the cervix, and confirmation that all findings are consistent with BV, versus 
Candidiasis or other causes of the patient’s vaginal signs or symptoms. Any observed abnormalities will 
be assessed and documented in the source document and eCRF.  
10.3.9 
Specimen Collection  
At Screening, swabs will be collected and submitted for the Candida culture, Chlamydia trachomatis and 
Neisseria gonorrhoeae NAATs, and the OSOM® test for Trichomonas vaginalis (which will be 
performed onsite). A swab of the vaginal pool should be utilized to perform a microscopic wet mount 
evaluation for clue cells (as part of Amsel’s criteria) as well as other elements (e.g., white blood cells, 
trichomonads, yeast, bacteria, etc.). Vaginal samples will also be used for microscopic KOH wet mount 
evaluations to assess the presence of Candida species.  
A swab of the lateral vaginal wall should be utilized for the slides to be submitted for centralized Gram 
staining for Nugent scoring. Instructions for the sampling for all procedures, including vaginal Candida 
cultures, preparation of slides for Nugent scoring, and NAAT and OSOM® testing, will be included in the 
laboratory manual and/or other study documents.  
10.3.10 
Prior and Concomitant Medications 
All medications taken during the 30 days prior to signing the ICF or used during the patient’s study 
participation will be recorded at each visit and documented in the eCRF. 
10.3.11 
Adverse Events 
Assessment of AEs will be completed at all visits. Any untoward events reported by the patient or 
observed by the study staff during or following treatment are to be recorded as AEs. (Events that occur 
after signing the ICF but before treatment with study drug are to be recorded and reported either as 
medical history or pre-treatment AEs, as appropriate.) Refer to Section 10.4 for details regarding 
definitions, documentation, and reports of AEs and SAEs.

10.3.12 
Local Site Reactions 
At each visit the Investigator or designee will perform a vulvar-vaginal examination to assess the 
treatment area and rate the following on a scale of 0 = absent, 1 = mild (slight, barely perceptible), 2 = 
moderate (distinct presence), and 3 = severe (marked, intense):  
 
Erythema  
 
Petechiae  
 
Erosion/ulceration  
 
Edema  
The patient will be queried by the Investigator or designee for presence of the following and, if present, 
the patient will be asked to rate as described above:  
 
Burning/stinging  
 
Pain  
 
Pruritus (itching)  
A separate eCRF will be designed to identify, track and characterize all local site reactions; therefore, 
vulvovaginal symptoms should be reported as TEAEs only if they are of a magnitude suggesting a 
clinically significant worsening compared to the patient’s baseline condition, or they require medical 
intervention.  
10.3.13 
Acceptability Assessment 
Patients will provide responses to questions of product acceptability, including the patient’s experience 
with changes in odor and discharge. Additionally, information will be collected to understand the 
patient’s experience with the study drug itself, e.g., ease of application, messiness or lack thereof, etc.  
10.3.14 
Pharmacokinetics and Vaginal Clindamycin Assessments 
For patients that have agreed and consented to participate in the PK subset group, PK blood draws will be 
done at 0 hours (pre-dose) and then at 2, 4, 6, and 8 hours (±15 minutes) post-dose (Day 1), as well as at 
24, 48, 72, 96, 120, and 144 hours (±2 hours) post-dose (Days 2-7).  
Also in the PK subset, samples will be collected for assessment of vaginal clindamycin concentrations at 
baseline (pre-dose only on Day 1; i.e., vaginal clindamycin samples will not be collected at post-dose 
time points on Day 1) as well as post-treatment on Days 2-7. 
10.4 
ADVERSE EVENTS AND SERIOUS ADVERSE EVENTS 
10.4.1 
Definition of Adverse Events 
An AE in a study of an investigational drug is any untoward medical occurrence, unintended disease or 
injury or any untoward clinical signs (including an abnormal laboratory finding) associated with the use 
of a drug in humans, whether or not considered related to the drug. 
10.4.2 
Definition of Serious Adverse Events 
An event is considered an SAE if, in the view of either the Investigator or Sponsor, it meets the criteria as 
outlined in 21 CFR 312.32 (a) as per the following:  

Clinical Study Protocol 
DARE-BV1-001 
Daré Bioscience, Inc. 
 
Version/Date: 4.0/14 Aug 2020 
Page 43 of 56 
An adverse event or suspected adverse reaction is considered "serious" if, in the view of either the 
Investigator or Sponsor, it results in any of the following outcomes: Death, a life-threatening 
adverse event, inpatient hospitalization or prolongation of existing hospitalization, a persistent or 
significant incapacity or substantial disruption of the ability to conduct normal life functions, or a 
congenital anomaly/birth defect. Important medical events that may not result in death, be life-
threatening, or require hospitalization may be considered serious when, based upon appropriate 
medical judgment, they may jeopardize the patient or subject and may require medical or surgical 
intervention to prevent one of the outcomes listed in this definition. Examples of such medical 
events include allergic bronchospasm requiring intensive treatment in an emergency room or at 
home, blood dyscrasias or convulsions that do not result in inpatient hospitalization, or the 
development of drug dependency or drug abuse.  
10.4.3 
Classification of an Adverse Event 
10.4.3.1 
Severity of Event 
The Investigator is responsible for assessing the severity of each AE using the following definitions: 
 
Mild: Symptoms causing no or minimal interference with usual social and functional activities 
with intervention not indicated. 
 
Moderate: Symptoms causing greater than minimal interference with usual social and functional 
activities with intervention indicated. 
 
Severe: Symptoms causing inability to perform usual social and functional activities with 
intervention or hospitalization indicated. 
It is important to distinguish between serious and severe AEs. Severity is a measure of intensity whereas 
seriousness is defined by the criteria under Section 10.4.2. An AE of severe intensity may not be 
considered serious. 
If there is a change in severity of an AE, it must be recorded as a separate event. 
10.4.3.2 
Relationship to Study Intervention 
An Investigator who is qualified in medicine (e.g., MD, NP, DO) must make the determination of 
relationship to the study drug for each AE. The Investigator should decide whether, in his or her medical 
judgment, there is a reasonable possibility that the event may have been caused by the investigational 
product. For each AE, the assessment of relatedness should be made using the following scale: 
 
Unrelated: Onset of the AE had no reasonable temporal relationship to administration of the study 
product or a causal relationship to administration of the study product is biologically implausible 
or the event is attributed to an alternative etiology. 
 
Possibly Related: Onset of the AE has a reasonable temporal relationship to study product 
administration and a causal relationship is not biologically implausible. 
 
Probably Related: Onset of the AE has a strong temporal relationship to administration of the 
study product that cannot be explained by the patient’s clinical state and a causal relationship is 
not biologically implausible. 
 
Definitely Related: Onset of the AE shows a distinct temporal relationship to administration of 
the study product that cannot be explained by the patient’s clinical state or other factors or the AE 
is a known reaction to the product or chemical group or can be predicted by the product’s 
pharmacology.

If the relationship between the AE/SAE and the investigational product is determined to be “possible,” 
“probable,” or “definite” the event will be considered related to the investigational product for the 
purposes of expedited regulatory reporting. 
10.4.4 
Time Period and Frequency for Event Assessment and Follow-up 
All AEs must be recorded in detail in the source documentation, reported on the appropriate page in the 
eCRF, and followed to satisfactory resolution, until the Investigator deems the event to be chronic or not 
clinically significant, until the patient is considered to be stable, or when a plan for appropriate follow-up 
has been approved by the Medical Monitor. 
10.4.5 
Adverse Event Reporting 
All AEs reported or observed during the study shall be recorded in the source documentation and reported 
on the AE page in the eCRF. Information to be collected includes the patient’s study ID number, age, site, 
concomitant drug treatment, and dose (if available), event term, time of onset, Investigator-specified 
assessment of severity and relationship to study drug, time of resolution of the event, seriousness, any 
required treatment or evaluations, outcome, and period of study at onset (at screening, during treatment, 
or at follow-up). Adverse events resulting from concurrent illnesses, reactions to concurrent illnesses, 
reactions to concomitant medications, or progression of disease states must also be reported. All AEs 
shall be followed-up until adequate resolution. The Medical Dictionary for Regulatory Activities 
(MedDRA) shall be used to code all AEs. 
Any medical condition that is present at the time the patient is screened but does not deteriorate after 
treatment shall not be reported as an AE. However, if it deteriorates at any time during the study, it shall 
be recorded as an AE. 
10.4.6 
Serious Adverse Event Reporting 
Any AE that meets SAE criteria must be reported to the Sponsor or designee immediately (within 
24 hours) after the time site personnel first learn about the event.  
The study clinician shall immediately report to the Sponsor or designee any SAE, whether or not 
considered study intervention related, including those listed in the protocol or Investigator’s Brochure, 
and must include an assessment of whether there is a reasonable possibility that the study intervention 
caused the event.  
All SAEs shall be followed-up until satisfactory resolution or until the site Investigator deems the event to 
be chronic or the patient is stable. Other supporting documentation of the event may be requested by the 
study Sponsor or designee and shall be provided as soon as possible. 
The study Sponsor or designee shall be responsible for notifying the U.S. FDA of any unexpected fatal or 
life-threatening suspected adverse reaction as soon as possible, but in no case later than 7 calendar days 
after the Sponsor’s or designee’s initial receipt of the information. In addition, the Sponsor or designee 
must notify the U.S. FDA and all participating Investigators in an Investigational New Drug (IND) safety 
report of potential serious risks, from clinical trials or any other source, as soon as possible, but in no case 
later than 15 calendar days after the Sponsor or designee determines that the information qualifies for 
reporting. 
The Sponsor or designee and all applicable Investigators are also responsible for reporting new safety 
information to regulatory agencies as required in accordance with applicable local laws and regulations.

10.4.7 
Reporting of New Information to Patients 
Study patients will be notified in a timely manner of any new safety information that may affect their 
consent to participate in the study. 
10.4.8 
Reporting of Pregnancy 
All pregnancies that occur while a patient is participating in the study will be reported immediately 
(within 24 hours) to the Sponsor or designee and monitored until outcome. Information from medical 
records will also be collected on pregnancy outcome data including maternal or fetal complications, 
spontaneous or elective abortions, ectopic pregnancies, stillbirths, and live preterm and full-term births. 
Although pregnancy itself is not an AE, any complications during pregnancy should be recorded as AEs 
or SAEs (if they fulfill the SAE criteria). Offspring should be followed for a minimum of 8 weeks. Any 
congenital anomaly/birth defect in a child born to a patient exposed to the test article(s) should be 
recorded as a SAE and details appropriately documented. Spontaneous abortions will be considered 
non-serious unless associated with consequences that meet seriousness criteria. 
Patients who are pregnant at the time of study enrollment will also be followed until delivery/termination 
of pregnancy and their offspring followed for a minimum of 8 weeks.  The same information collected for 
patients who become pregnant during the study will be collected on patients who enter the study while 
pregnant.   
11 
STATISTICAL CONSIDERATIONS 
A detailed statistical analysis plan (SAP) will be finalized before the treatment assignments for all 
patients are unblinded and prior to locking the database to expand upon the statistical methods presented 
below. 
11.1 
STATISTICAL HYPOTHESES 
The hypothesis test for the primary endpoint will be done to determine if DARE-BV1 is superior to 
placebo for Clinical Cure at the TOC visit (Visit 3; Day 21-30). 
11.2 
RANDOMIZATION AND STRATIFICATION 
Randomization will be done in a 2:1 ratio (DARE- BV1 [clindamycin phosphate vaginal gel. 2%]: 
placebo vaginal gel). The randomization schedule will be generated using SAS® version 9.4 or higher. 
The randomization schedule will be stratified by site and race (African-American/Black versus all others). 
11.3 
SAMPLE SIZE DETERMINATION 
The sample size calculations were performed using SAS® version 9.4 for the 2-group chi-square test. It is 
expected that this test will provide approximately the same power as the Cochran-Mantel-Haenszel 
(CMH) test stratified by analysis center and race. A sample size of 188 DARE-BV1 versus 94 placebo 
patients (282 patients total) will have 90% power to detect a statistically significant difference at a 
significance level of 0.05 (2-tailed) under the assumption the clinical cure rates will be 55% and 30% for 
DARE-BV1 and placebo, respectively. This sample size assumes 35% of randomized patients will not be 
in the mITT population.

11.4 
POPULATIONS FOR ANALYSES 
Intent-to-Treat (ITT): All randomized patients 
Safety: All ITT population patients who applied study drug 
PK Subset (PKS): All Safety population patients who are enrolled into the PK subset 
Modified Intent-to-Treat (mITT): All Safety population patients except those excluded due to 
demonstrating a positive test result for other concomitant vaginal or cervical infections at baseline 
(e.g., T. vaginalis, N. gonorrhoeae, C. trachomatis, Candida species) or who are determined to have a 
baseline Nugent score of < 7. If the Nugent score at baseline is missing, then the patient is excluded from 
the mITT population.  
Per-Protocol (PP): The PP population will include patients from the mITT population who either receive 
other BV therapy during the study for any reason, or meet the following criteria: 
 
Meet all 4 Amsel’s criteria at screening 
 
Apply study drug within 1 day of randomization 
 
Do not use a prohibited medication prior to the Day 21-30 visit 
 
Attended the Day 21-30 visit  
 
Have no other major protocol violations that impacted the primary or secondary endpoints. 
For the mITT and PP populations, if the patient receives other BV therapy for any reason, the patient will 
be included in the analysis as a treatment failure for all visits on or after receipt of the other therapy. 
Patients will be excluded from the PP population if they received study treatment that was not the 
treatment to which they were randomized. A review of the data will be performed prior to locking the 
database and unblinding the study to determine which medications and major protocol violations would 
impact the primary and secondary endpoints and cause a patient to be excluded from the PP population. 
11.5 
STATISTICAL ANALYSES 
11.5.1 
General Approach 
All statistical processing will be performed using SAS®, Version 9.4, or later. Continuous variables will 
be summarized with number of patients (N), mean, median, standard deviation (SD), minimum (Min), 
and maximum (Max). Categorical variables will be summarized with frequency counts and percentages. 
All efficacy analyses will be conducted using a 2-sided test at an alpha level of 0.05. The primary efficacy 
analyses will be conducted on the mITT population. Additionally, efficacy analyses will be performed on 
the PP population and will be considered supportive. Safety analyses will be performed on the Safety 
population. Patients will be analyzed according to the treatment to which they were randomized for ITT 
and mITT analyses, regardless of actual treatment received. For all other analysis populations, patients 
will be analyzed according to the treatment they received. 
11.5.2 
Analysis of the Primary Efficacy Endpoint 
All efficacy endpoints will be summarized for each treatment group using descriptive statistics, including 
95% confidence intervals (within treatment group), as appropriate. 
The primary efficacy analysis of Clinical Cure at Day 21-30 will be analyzed for the mITT population 
with a CMH test stratified by study center and race (African-American/Black versus all others). The 

Clinical Study Protocol 
DARE-BV1-001

Version/Date: 4.0/14 Aug 2020 
Page 47 of 56 
method for handling of patients in the mITT analysis without a Clinical Cure result at Day 21-30 will be 
included in the final SAP. 
Patients who receive other BV treatment(s) for any reason will be included in the analysis as treatment 
failures for all visits on or after receipt of the other therapy(ies). 
11.5.3 
Analysis of the Secondary Endpoints 
Hypothesis testing for the secondary efficacy endpoints will be conducted in a sequential manner to 
control the Type 1 error rate, in the order presented below: 
1. Proportion of patients in the mITT population with Bacteriological Cure at the TOC visit 
(Day 21-30). Bacteriological Cure is defined as a Nugent score < 4. 
2. Proportion of mITT patients with Therapeutic Cure at the TOC visit (Day 21-30). Therapeutic 
Cure is defined as both a Clinical Cure and Bacteriological Cure (Nugent Score < 4). 
3. Proportion of mITT patients with Clinical Cure at the Interim Assessment visit (Day 7-14). 
4. Proportion of mITT patients with Bacteriological Cure (Nugent score < 4) at the Interim 
Assessment visit (Day 7-14). 
5. Proportion of mITT patients with Therapeutic Cure at the Interim Assessment visit 
(Day 7-14).  
Analysis of the secondary endpoints will follow the same method as the analysis of the primary endpoint, 
including patients being included in the analysis as treatment failures if other BV treatments were 
received (i.e., treatment failure status will be applied to all visits on or after receipt of the other BV 
treatment).  
The PP population will be used to perform sensitivity analyses of the above primary and secondary 
efficacy analyses. Patients in the PP population without a Clinical Cure result at Day 21-30 will be 
excluded from the PP analyses. 
11.5.4 
Safety Analyses 
Descriptions of AEs will include the date of onset, the date the AE ended, the maximum severity of the 
AE, relationship to study drug, seriousness, any action taken, and the outcome. 
All TEAEs occurring during the study will be recorded and classified on the basis of MedDRA 
terminology. Treatment-emergent AEs are those AEs with an onset at the time of or after the application 
of study drug. All reported TEAEs will be summarized by treatment group, system organ class and 
preferred term. Adverse event summaries will include severity, relationship to study drug, and 
seriousness. When summarizing events by causality and severity, each patient will be counted only once 
within a system organ class or a preferred term by using the event with the greatest relationship and 
highest severity within each classification. In addition, a list of patients who had an SAE or who 
prematurely discontinued from the study due to an AE will be provided. 
Changes from baseline and shifts from baseline will be summarized for safety laboratory results. A listing 
that displays all out-of-range laboratory test results will also be provided.  
Local site reactions will be summarized at each visit. 
Changes from baseline to each visit will be summarized for other safety parameters (e.g., vital signs, 
pelvic examination).

The following PK parameters will be summarized for the PKS population to assess plasma and vaginal 
clindamycin concentration levels for Days 1-7:  
 
minimum concentration (Cmin)  
 
maximum concentration (Cmax)  
 
area under the curve (AUC0-t), where t is the last time-point with measurable concentration)  
 
time to maximum concentration (Tmax)

elimination half-life (t1/2) 
Descriptive summaries of plasma clindamycin levels will be presented for each timepoint. 
11.5.6 
Baseline Descriptive Statistics 
Demographic data and other baseline characteristics including medical and medication history will be 
summarized as appropriate. 
11.5.7 
Product Acceptability  
Patients will provide responses to questions of product acceptability, including the patient’s experience 
with changes in odor and discharge. Additionally, information will be collected to understand the 
patient’s experience with the study drug itself, e.g., ease of application, messiness or lack thereof, etc. The 
results will be summarized for the Safety population. 
11.5.8 
Planned Interim Analyses 
No interim analyses are planned. 
11.5.9 
Sub-group Analyses 
Any sub-group analyses will be defined in the SAP that will be finalized prior to database lock.

Page 49 of 56 
Before study onset, the protocol, ICF, advertisements to be used for the recruitment of study subjects, and 
any other written information regarding this study to be provided to the subject or the subject’s legal 
guardian must be approved by the IRB. Documentation of all IRB approvals and of the IRB compliance 
with ICH Harmonised Tripartite Guideline E6 (R2): GCP will be maintained by the site and will be 
available for review by the Sponsor or its designee. 
All IRB approvals must identify the IRB name and address, the clinical protocol by title or protocol 
number or both, and the date approval or a favorable opinion was granted. 
The Investigator is responsible for providing written summaries of the progress and status of the study as 
specified by the IRB. The Investigator must promptly supply the Sponsor or its designee, the IRB, and, 
where applicable, the institution, with written reports on any changes significantly affecting the conduct 
of the study or increasing the risk to subjects. 
12.1.3 
Informed Consent Process 
A written ICF in compliance with ICH Guideline for GCP E6 (R2) and U.S. Title 21 CFR Part 50 will be 
obtained from each patient before entering the study. No study-related procedures or activities will be 
performed until each patient is fully informed about the study and the ICF is properly signed and dated. 
An ICF template will be provided by the Sponsor or designee to investigative sites. If any institution-
specific modifications to study-related procedures are proposed or made by the site, the ICF will be 
reviewed by the Sponsor and/or its designee before IRB submission. Once reviewed, the ICF will be 
submitted by the Investigator or Sponsor/designee (as applicable) to the IRB, and when applicable to 
regulatory authorities, for review and approval before the start of the study. If the ICF is revised during 
the course of the study, all active participating patients to whom the change is applicable must sign the 
revised form. Reconsent will be needed before rescreening a patient. 
Before enrollment, each prospective patient and/or her parent(s)/legal guardian(s) will be given a full 
explanation of the study and be allowed to read the IRB-approved ICF. Once the Investigator is assured 
that the patient/legal guardian understands the implications of participating in the study, the patient, 
parent(s), and/or legal guardian(s) will be asked to give consent/assent to participate in the study by 
signing the ICF. 
The Investigator will retain the signed original ICF and give a copy of the signed original ICF to the 
patient or legal guardian. 
Patients aged 12 through 17 years old may participate where permitted by applicable local regulations and 
IRB approval. All applicable laws and regulations regarding the informed consent of minors are to be 
strictly observed. 
12.1.4 
Study Discontinuation and Closure 
The Sponsor reserves the right to modify or terminate the study at any time. Possible reasons for 
termination are unsatisfactory enrollment of patients, new scientific knowledge becomes known that 
makes the objectives of the study no longer feasible, efficacy or safety reasons, e.g., if the incidence of 
AEs in this study or another study using the same investigational product indicates there is a potential 
health risk for patients. 
The Sponsor or designee will provide a written statement to the IRB and the relevant regulatory authority 
with the reasons for modification or termination of the study. If the study is terminated, a closeout visit 
will be performed at each active site at which study investigational product was received and at least 

Clinical Study Protocol

Page 50 of 56 
1 patient was screened, and applicable procedures will be carried out to close the trial site(s). The Sponsor 
reserves the right to discontinue the study at any time for clinical or administrative reasons. 
The end of the study is defined as the date on which the last patient completes the last visit or the last 
contact by which study-related data is conveyed. 
12.1.5 
Potential Impact of the COVID-19 Pandemic 
The DARE-BV1-001 study is being conducted while the United States is contending with the COVID-19 
pandemic.  In March 2020, the FDA released a document entitled “FDA Guidance on Conduct of Clinical 
Trials of Medical Products during COVID-19 Public Health Emergency;” this document was then further 
updated on April 16, 2020.  This guidance acknowledges various ways in which the pandemic could 
impact clinical trials, as per the following excerpt:  
“FDA recognizes that the COVID-19 public health emergency may impact the conduct of clinical 
trials of medical products. Challenges may arise, for example, from quarantines, site closures, travel 
limitations, interruptions to the supply chain for the investigational product, or other considerations 
if site personnel or trial subjects become infected with COVID-19. These challenges may lead to 
difficulties in meeting protocol-specified procedures, including administering or using the 
investigational product or adhering to protocol-mandated visits and laboratory/diagnostic testing. 
FDA recognizes that protocol modifications may be required, and that there may be unavoidable 
protocol deviations due to COVID-19 illness and/or COVID-19 public health control measures.” 
In addition to the need for sites to implement procedures to ensure the safety of its patients and staff, the 
sponsor and CRO study teams have taken additional steps to contend with the potential consequences of 
the pandemic.  For example, there will be increased reliance on remote monitoring, and additional 
documentation will be maintained to track operational disruptions or other study issues secondary to the 
consequences of the COVID-19 pandemic.  Additional details are provided in the study Clinical 
Management Plan.   
12.1.6 
Confidentiality and Privacy 
All laboratory specimens, evaluation forms, reports, and other records will be identified in a manner 
designed to maintain patient confidentiality. All records shall be kept in a secure storage area with limited 
access. Clinical information shall not be released without the written permission of the patient (or the 
patient’s legal guardian), except as necessary for monitoring and auditing by the Sponsor, its designee, the 
IRB, or applicable regulatory authorities (e.g., the U.S. FDA), or unless otherwise required by law. 
The Investigator and all employees and coworkers involved with this study may not disclose or use for 
any purpose other than performance of the study any data, record, or other unpublished, confidential 
information disclosed to those individuals for the purpose of the study. Prior written agreement from the 
Sponsor or its designee must be obtained for the disclosure of any said confidential information to other 
parties. 
12.1.7 
Future Use of Stored Specimens and Data 
No laboratory specimens will be retained after the end of the study.

Key Roles and Study Governance 
The Medical Monitor, or a designated backup, will serve as the primary contact for site medical questions 
related to the study. 
12.1.9 
Safety Oversight 
The Medical Monitor, or a designated backup, will conduct periodic reviews of study safety data to 
identify any potential safety concerns.  
12.1.10 
Clinical Monitoring 
The clinical monitor, as a representative of the Sponsor, has the obligation to follow the study closely. In 
doing so, the monitor shall visit the Investigator and study site at periodic intervals, in addition to 
maintaining necessary telephone and other contacts. At sites where in-person monitor visits are not 
feasible due to the COVID-19 pandemic, virtual monitor visits will be permitted.  The monitor shall 
maintain current personal knowledge of the study through observation, review of study records and 
source documentation, and discussion of the conduct of the study with the Investigator and personnel. 
Remote monitoring of the eCRF will also be employed for this trial.  Additional details regarding clinical 
monitoring can be found in the trial Clinical Management Plan. 
All aspects of the study shall be carefully monitored, by the Sponsor or its designee, for compliance with 
applicable regulations. 
12.1.11 
Quality Assurance and Quality Control 
This study shall adhere to U.S. FDA standards as well as other applicable local standards of conduct 
regarding quality assurance. All parts of the U.S. CFR applicable to clinical studies, including 
21 CFR Parts 50, 56, and 312, must be followed, along with ICH E6 (R2). 
Suitably qualified and trained clinical research personnel of the Sponsor or designee shall visit the trial 
site at regular intervals during the trial for monitoring purposes and to assist the research staff with any 
queries. The eCRFs and source documentation shall be available for review during monitoring visits to 
the trial site. The function of this monitoring is to ensure compliance with the protocol and study 
procedures, applicable regulatory and GCP obligations, proper maintenance of records including study 
drug accountability records, correct administration of study drug including storage conditions, and 
accurate reporting of AEs. After data from the patient’s records have been entered onto the database, they 
shall be reviewed and the data verified against the patient’s source data (details of data verification, 
including the percentage of data fields requiring source verification, shall be documented in a Monitoring 
Plan). Any discrepancies shall be tracked by paper or electronically with an electronic audit trail. 
The Sponsor, an independent auditor, or a regulatory authority may audit the trial site and trial 
documentation. These audits may take place while the trial is being conducted or up to several years later. 
12.1.12 
Data Handling and Record Keeping 
Investigators and institutions involved in the study shall permit study-related monitoring, audits, IRB 
review, and regulatory inspections by providing direct access to all study records. In the event of an audit, 
the Investigator agrees to allow the Sponsor, representatives of the Sponsor, or a regulatory agency (i.e., 
U.S. FDA or other regulatory agency) access to all study records. 

Clinical Study Protocol

Page 52 of 56 
The Investigator shall promptly notify the Sponsor or designee of any audits scheduled by any regulatory 
authorities and promptly forward copies of any audit reports received to the Sponsor or designee. 
12.1.12.1 Data Collection and Management Responsibilities 
As part of the responsibilities assumed by participating in the study, the Investigator agrees to maintain 
adequate case histories for the patients treated as part of the research under this protocol. The Investigator 
agrees to maintain accurate source documentation as part of the case histories. These source documents 
may include, but are not limited to, laboratory reports, histology reports, and ultrasound findings. 
Investigative site personnel shall enter patient data into the eCRF. Clinical data management shall be 
performed in accordance with applicable standards and data cleaning procedures to ensure the integrity of 
the data, e.g., removing errors and inconsistencies in the data. Adverse events will be coded using 
MedDRA and concomitant medication terms will be coded using the World Health Organization Drug 
Dictionary (WHO-DD). 
12.1.12.2 Study Records Retention 
Following completion of the study, the Investigator shall retain copies of the approved study protocol, 
ICF, relevant source documents, and all other supporting documentation related to the study according to 
the ICH guidelines. 
If the Investigator can no longer maintain the archive of study records (i.e., due to retirement or 
relocation), the Sponsor must be informed in writing about any change in responsibility for record 
retention, including the name of the new responsible party, contact information, and location of the study 
records. Records may not be destroyed without prior written consent from the Sponsor. 
12.1.13 
Protocol Deviations 
A protocol deviation occurs when the patient, Investigator, or Sponsor fails to adhere to significant 
protocol requirements affecting the inclusion, exclusion, patient safety and primary endpoint criteria. 
Protocol deviations for this study include, but are not limited to, the following: 
 
Failure to meet inclusion/exclusion criteria 
 
Enrolling a patient into the study without securing proper consent 
 
Deviating from the protocol-defined study procedures 
Certain protocol deviations may require the patient to be discontinued early from the study. The Sponsor, 
in conjunction with the Investigator, will determine if a protocol deviation should result in withdrawal of 
a patient.  
Failure to comply with GCP guidelines will also result in a protocol deviation. It is the responsibility of 
the research sites to report all protocol deviations to their IRB according to IRB policy. 
12.1.14 
Publication and Data Sharing Policy 
All information concerning the study supplied by the Sponsor to the Principal Investigator and not 
previously published is considered confidential. No data collected in this study will be presented or 
published without prior approval from the Sponsor.
