PROTOCOL SYNOPSIS 
 
TITLE OF CLINICAL TRIAL: 
Phase 2B/3 double-blinded placebo-controlled efficacy trial of AMPHORA® gel for the 
prevention of acquisition of urogenital Chlamydia trachomatis infection 
INVESTIGATIONAL PRODUCT(S): 
Eligible subjects will receive: 
AMPHORA vaginal gel, supplied in individually wrapped 5 g single-dose, pre-filled vaginal 
applicators. AMPHORA is a dense, viscous, off white to tan gel of uniform consistency. Its 
active ingredients are L-lactic acid United States Pharmacopeia (USP), citric acid USP, and 
potassium bitartrate USP, with alginic acid and xanthan gum included as viscosity and 
bioadhesive controllers 
CLINICAL PHASE: Phase 2B/3 
CLINICAL TRIAL OBJECTIVES: 
Primary: 
• To determine if intravaginal AMPHORA gel reduces the risk of urogenital Chlamydia 
trachomatis (CT) infection 
Secondary: 
• To determine if intravaginal AMPHORA gel reduces the risk of urogenital Neisseria 
gonorrhoeae (GC) infection 
Exploratory: 
• To determine if AMPHORA gel use rate (subject adherence to instructed use) has an 
effect on proportion of subjects who experience at least one CT or GC infection 
during the study intervention period 
• To assess subject satisfaction (including sexual satisfaction) with AMPHORA gel 
over the course of the clinical study 
OUTCOME MEASURES: 
Primary: 
• Proportion of subjects who experience at least one urogenital CT infection during the 
study intervention period (incident infection of CT) 
Secondary: 
• Proportion of subjects who experience at least one urogenital GC infection during the 
study intervention period (incident infection of GC)

Page 10 of 76 
Exploratory: 
• Compliance with AMPHORA usage during study (rate of product use adherence)  
• Sensitivity analyses of the primary parameter (proportion of subjects who experience 
at least one CT or GC infection during the study intervention period) will be 
performed for the following: 
o Subjects with ≥20%, ≥40%, ≥60%, ≥80% and 100% product use adherence 
• Subject satisfaction  
• Sexual satisfaction 
CLINICAL TRIAL DESIGN: 
This is a Phase 2B/3 double-blind, placebo-controlled study in approximately 50 sites in the 
United States (US) over approximately 16 weeks of use in women aged 18 to 45 years who 
are at risk of urogenital re-infection  
TREATMENT DURATION: 
After a screening period of up to 45 days, women will be randomized to receive either 
AMPHORA or placebo. Each woman will participate in the study until after she has 
completed 16 weeks of treatment. The final visit to the clinical site will take place 4 weeks 
after the end of treatment even if the subject discontinues treatment prematurely 
SAMPLE SIZE: 
A sample of approximately 844 women will receive AMPHORA or placebo 
STUDY POPULATION:

Background Information 
Chlamydia trachomatis (CT) infection remains the most frequently reported infectious disease in 
the United States (US) (1). Several sequelae can result from CT infection in women, the most 
serious of which include pelvic inflammatory disease (PID) and scarring of the fallopian tubes, 
ovaries, endometrial lining, and occasionally, adjacent perineum, which increases the risk of 
future ectopic pregnancy and tubal infertility. These consequences are the main reason that CT 
infection is estimated to be the costliest of all non-viral sexually transmitted infections (STIs) 
(2). 
An acidic vaginal pH and colonization with Lactobacillus species (LB) are two proven 
components of the multiple defense mechanisms active against infection in the lower female 
genital tract (3). These species are thought to play key protective roles by producing various 
bacteriostatic and bactericidal compounds (4), (5), (6). A lower vaginal pH may inhibit STIs, 
including CT infection (7). In vitro studies have shown that exposure to vaginal secretions at 
lower pH significantly inhibits CT replication (7), (8). In another experiment, the growth of CT 
within epithelial cells was inhibited by acidic pH (9). 
 
A prospective case-controlled study found an association between CT infection and higher 
vaginal pH (median pH of 4.5 in CT and 4.0 in controls, respectively), independent of any other 
factors (10). The study included 144 cases of CT infections and 145 controls. Sixty-two (62) of 
the women with CT were diagnosed with concurrent STIs (bacterial vaginosis [BV], genital 
warts, Neisseria gonorrhoeae [GC], trichomoniasis, and candidiasis). However, even when the 
analyses were restricted to the 82 cases that did not have any other concurrent STI, vaginal pH 
remained higher in those cases than in the controls. In univariate analyses, cases were over six 
times as likely as controls to have a pH >4.5. This study, in itself, was unable to answer whether 
lower vaginal pH reduces risk of acquisition of urogenital CT infection, and further study is 
needed. However, the results of this study lead to the hypothesis that reduction of vaginal pH 
(through treatment) in asymptomatic women with conditions that are known to increase vaginal 
pH (such as BV), may help to prevent CT infection, particularly in those at increased risk of 
infection.  
 
A recent study of 61 women exposed to GC through an infected partner was conducted at the 
Baltimore City Health Department STI clinics and showed that 100% of the women whose 
vaginal pH was ≥5.0 were subsequently infected with GC versus 40% of the women whose pH 
was <5.0 (when measured within 5 days of GC exposure) (11). Additionally, pH-dependent risk 
was independent of BV as diagnosed by Amsel criteria. These data suggest that modification of 
vaginal pH could be used clinically to reduce risk of GC infection in women.

In summary, the interplay between vaginal pH and the naturally occurring human vaginal 
microbiota represents an important relationship which has been linked to increased risk for STIs, 
including CT and GC (12), (13), (14), (15), (16), (17), (18), (19), (20), (21).  
1.2 
Scientific Rationale 
AMPHORA is an acid-buffering vaginal gel (pH 3.5) containing three active ingredients 
(L-lactic acid, citric acid, and potassium bitartrate). It is currently in development as a 
contraceptive to be applied intravaginally before sexual intercourse. During development, it was 
found to have in vitro activity against GC, as well as BV-associated microbes, without having a 
detrimental effect on beneficial native LB and to inhibit Trichomonas vaginalis under both 
aerobic and anaerobic conditions (Investigator’s Brochure, 2016). This has led to further 
development as a microbicide to lessen the risk of, or prevent acquisition of, STIs. 
Subsequent studies done on AMPHORA in the animal model support further in vivo microbicide 
research. AMPHORA with and without nonoxynol-9 (N-9) was applied vaginally to Swiss 
Webster mice before inoculation of 15 µL 104 or 105 inclusion forming units [IFU] CT. 
AMPHORA was found to provide protection against upper genital tract infection in 88% to 
100% of the animals, whereas the other four vaginal gel products tested protected only 0% to 
38% of the animals. It was also determined that the addition of 5% N-9 to AMPHORA did not 
enhance its protective effect at the usual challenge inoculum (22). 
In another murine study, AMPHORA displayed significant protection against transmission of 
GC with only one of 17 mice treated having positive culture results compared with 13 of 15 
untreated control mice. Of the six topical microbicide agents tested, AMPHORA was the most 
highly active against GC in vitro; a 0.625% solution of this product inhibited six of the seven GC 
strains (23). 
Low adherence to product use is an ongoing challenge in vaginal microbicide studies, though 
recent analysis of study data has produced baseline predictors of high adherence (24). A recent 
prospective study on sexual risk behavior and incident STIs included a substudy that showed use 
of cell phone-based e-diaries assisted in achieving an enhanced subject compliance rate of 89.7% 
(25).

Study Design 
Eight hundred forty-four (844) women, ages 18 to 45, who have had a documented urogenital 
chlamydia or gonorrhea infection at any time over the 16 weeks preceding the Enrollment Visit, 
or found to be positive at Screening Visit will be enrolled. A high prevalence of Chlamydia 
trachomatis infection has been observed in those who were treated for urogenital chlamydial 
infection during the preceding several months. The second infection may result from re-infection 
through an untreated partner or exposure through a new partner. By including only women who 
have had a CT infection within the past 16 weeks, this study targets those at high risk for 
infection (1), (26).  
Regardless of whether a potential subject agrees to participate in the study, subjects should be 
treated according to each site’s routine standard of care (SOC) for STI prevention which should 
follow the prevention strategies recommended by the Centers for Disease Control and Prevention 
(https://www.cdc.gov/std/tg2015/clinical.htm). These strategies include client-centered STI 
prevention counseling addressing subject’s individual risk factors and advice on the correct and 
consistent use of male condoms to prevent STIs and human immunodeficiency virus (HIV), as 
well as condom provision if part of the site’s SOC. Those who agree to participate (ie, subjects 
who provide informed consent) should be treated according to SOC prior to and throughout the 
study period as necessary. 
Subjects will be tested for current GC/CT infection by nucleic acid amplification test (NAAT) 
via vaginal swab. Those negative for current infection will be enrolled. Those who test positive 
for CT/GC infection will receive SOC treatment. To meet eligibility criteria, these subjects will 
not be enrolled until 3 to 4 weeks after screening (at least 21 days after treatment). 
Eligible participants will be enrolled and randomized 1:1 (422 subjects per treatment arm) to 
either AMPHORA or placebo; 5 g of AMPHORA or placebo will be supplied in pre-filled, 
single-dose applicators. A baseline vaginal pH and a full gynecologic exam (speculum) will be 
obtained at enrollment.  
Subjects are instructed to apply AMPHORA or placebo gel immediately before or up to one hour 
prior to coitus for the duration of the 16-week intervention period. AMPHORA or placebo is to be 
re-applied in the same manner for each occurrence of sexual intercourse. Subjects will keep an 
electronic diary (eDiary) to document and track sexual activity and product use. 
Every 4 weeks (5 visits), all subjects will return to the clinic for repeat CT/GC NAAT (vaginal 
swab), urine pregnancy (urinary human chorionic gonadotrophin [uHCG]) testing, eDiary review, 
and return of used and unused investigational product. Applicators will be visually inspected for 
use and staining will be performed to confirm vaginal insertion of used (empty) applicators. At 
Visits 2 to 4, subjects will be re-supplied with AMPHORA or placebo gel. At Visit 5, subjects will

return used and unused investigational product and continue to use their eDiaries but will not be 
resupplied with AMPHORA or placebo gel.  
Subjects will return for a follow-up visit 4 weeks after the intervention period. At this time, CT/GC 
NAAT (vaginal swab), pregnancy (uHCG) testing, and eDiary review will be performed. 
Screening and Eligibility 
Subjects who consent may be screened if they have a known case of CT or GC within 16 weeks 
of enrollment, or suspicion of current CT or GC infection (subsequently confirmed with NAAT 
test at Screening Visit). Subjects randomized within 45 days of initial screening do not need to 
be re-screened. 
Intervention and Follow-up Period 
The intervention period is defined as Visits 1 to 5. There is one follow-up visit (Visit 6) 4 weeks 
after the last intervention visit. These periods are outlined in the Schedule of Assessments (Table 
1). The protocol-defined period of observation is 20 weeks. 
Safety Follow-up After Protocol-defined Period of Observation 
This period includes safety follow-up as required by Good Clinical Practice (GCP) and standard 
clinical study practice. Adverse events (AEs) determined to be at least possibly related to the 
investigational product continuing after the final study visit (Visit 6) will be followed until 
resolution or stable status as determined by the Investigator. Applicable information is found in 
Section 6.3.

Study Enrollment and Retention 
No study procedures will be performed until informed consent is obtained. Eight hundred forty-
four (844) healthy female subjects, ages 18 to 45, will be enrolled.  
Subjects will be recruited through institutional review board (IRB)-approved materials, database 
queries, and word of mouth. Children, pregnant women, prisoners, and other vulnerable 
populations will not be enrolled.  
Screening will begin with the Investigator or designee providing an overview of the study to the 
potential subject. Subjects will be excluded if they do not understand the protocol and 
participation requirements and/or if they are unable, unlikely, or unwilling to comply with gel 
application as directed, eDiary recording, or follow-up visit attendance. All subjects who consent 
will be assigned a screening number. 
All eligibility criteria must be met for inclusion into the study; no waivers will be granted. 
In this study, subjects will be encouraged to strive for 100% product use adherence; however, 
emphasis will be placed on accurate and forthright eDiary recording of each coital event noting 
use or non-use of the product and any circumstance that may have impacted their decision to use 
or not use as directed under the study. Adherence to product use will be measured using a 
combination of eDiary reporting and number/inspection/staining of returned investigational 
product/gel applicators.  
Study retention strategies will include clear explanations during enrollment of the study schedule 
and procedures and financial payment and/or reimbursements. Study staff will be actively 
involved in engaging subjects and implementing systems for appointment reminders and follow-
up with missed visits.

Response System (IWRS) in a 1:1 fashion across the two intervention groups, AMPHORA or 

AMPHORA® 
Protocol: EVO-003 
Evofem, Inc. v6.0 – 25 January 2019 
 
 
CONFIDENTIAL AND PROPRIETARY 
 
Page 26 of 76 
placebo. Randomization will be stratified by site, and all documentation of this procedure and 
output will be saved with the IWRS vendor until the end of the study. Randomization will occur 
following enrollment and prior to issuance of investigational product to subjects.  
3.5 
Blinding 
Investigators and subjects in both intervention groups will remain blinded to their intervention 
assignment (AMPHORA or placebo) over the entire duration of the study (double-blind). The 
Sponsor, Evofem, Inc., will prepare the investigational product as well as placebo and supply 
these products in ready-to-dispense status.  
Any request from the Investigator for information about treatment administered to study subjects 
must be approved by the Medical Monitor. 
If the code must be broken in the case of an emergency for subsequent management of a subject, 
the Investigator must provide a written request with record of the circumstances surrounding the 
event, including the purpose, date, and personnel involved. Emergency unblinding will be 
available by using the IWRS. An emergency treatment disclosure is a reportable event that must 
be reported to the Medical Monitor within 24 hours of the event.  
Otherwise, blinding will not be broken until all subjects have completed the final study visit and 
the database has been locked and approved.  
3.6 
Withdrawal 
3.6.1 Reasons for Withdrawal 
A study subject will be discontinued from participation in the study for: 
• Development of any exclusion criteria  
• Positive GC/CT NAAT testing at enrollment 
• Pregnancy or breastfeeding 
• Request by subject to terminate participation 
• Subject is no longer sexually active on a regular basis, ie, records no sexual activity for 
two or more cycles 
• Requirement for prohibited treatment (see exclusion criteria) during the intervention 
period 
• Intervention-related toxicity 
• Lost to follow-up 
• Request of primary care provider

• Request of the IRB/ethics committee, US Food and Drug Administration (FDA), or 
Sponsor 
• Subject is no longer able to attend study visits and/or comply with study procedures 
• The subject’s well-being, based on the opinion of the Investigator  
3.6.2 Handling of Withdrawal 
If a subject is withdrawn from participation, the reason(s) for discontinuation must be 
documented in the source documents and electronic case report forms (eCRFs). The procedures 
for Visit 5 should be followed for the Early Termination Visit. Subjects who withdraw or are 
withdrawn from the study who received any amount of the investigational product will be 
encouraged to return to the clinic for a final visit to complete the post-intervention follow-up 
visit (all procedures from Visit 6). If an AE or serious adverse event (SAE) has occurred, every 
effort will be made to undertake protocol-specified safety follow-up procedures, and the subject 
will be encouraged to receive appropriate care under medical supervision until the symptoms of 
any AE resolve or the subject’s condition becomes stable.  
3.6.3 Handling Subjects Lost to Follow-up  
The study design has incorporated primary, secondary, and tertiary strategies for reducing the 
number of subjects lost to follow-up. Primary strategies include having sites: 1) fully inform 
subjects of study visit details prior to randomization, 2) addressing subjects’ expectations on 
study participation, 3) motivating subjects to adhere to follow-up visits and research protocols, 
and 4) utilizing eDiaries for data entry and review. Secondary strategies include: 1) scheduling 
all visits around subjects’ availability which are within the visit window, 2) providing a visit 
reminder ahead of time, and 3) reviewing data for missed and overdue follow-up visits. Tertiary 
strategies include: 1) discussing subjects’ difficulty in adhering to study protocol and answering 
any questions they might have and 2) continuing attempts to reach subjects lost to follow-up and 
recording all contact attempts.  
A subject will be considered as lost to follow-up if participation in study activities is not 
continued after: 
• Three attempts at telephone contact without success following missed study assessment 
timepoint, followed by 
• Issuance of a certified letter to last documented address of subject, and no response 
within 7 days of mailing 
Documentation of lost to follow-up status will be maintained in the subject’s case report form 
(CRF) and in source documents. The reason(s) for the lost to follow-up, if known, and the 
appropriate timelines for subject-study site correspondence will be captured along with the study 
site’s attempts to reach the subject. Lastly, all proper procedures of sending certified letter of

discontinuation from study based on lost to follow-up status and a recommendation to come in 
for a discontinuation visit to determine safety of the subject will be followed by the study site. 
The conditions and plans for replacement of subjects lost to follow-up are described in 
Section 3.6.3.  
3.6.4 Replacement of Subjects Lost to Follow-up and Withdrawal 
An enrolled subject will be considered lost to follow-up or withdrawn as described in 
Section 3.6.3 at any point prior to Visit 6 (post-intervention follow-up visit). Subjects will not be 
replaced in this study. 
3.7 
Subject Completion 
An enrolled subject will be considered a study completer once any of the following three 
criterion is met: 
1. Finishes all study visits without experiencing a urogenital CT or GC infection 
2. Experiences urogenital CT infection 
3. Experiences urogenital GC infection 
3.8 
Termination of the Study 
The study may be terminated at the discretion of the Sponsor. The study may also be terminated 
at a study site after discussion with the Sponsor. The reason for termination will be documented.

Study Products 
4.1 
Study Products Description 
There are two study products used over the course of the intervention period for this study: 
1) AMPHORA and 2) placebo. 
 
AMPHORA  
AMPHORA is in development as a vaginally administered contraceptive gel and microbicidal 
agent. AMPHORA is an acid-buffering gel (pH 3.5) containing three active ingredients (L-lactic 
acid 1.8%, citric acid 1%, and potassium bitartrate 0.4%) and the following non-active 
ingredients: benzoic acid, alginic acid, xanthan gum, glycerin, and water.  
 
Placebo (Universal Placebo Gel) 
The placebo used in this study is universal placebo gel (UPG). UPG is an isotonic non-buffering 
gel, with pH adjusted to 4.5 and containing 2.7% hydroxyethylcellulose, sorbic acid, sodium 
hydroxide, sodium chloride, and purified water. In clinical studies, UPG has been proven safe 
and acceptable when used up to twice daily for 14 days (27).

4.1.1 Formulation and Packaging  
For this study, pre-filled, single-use applicators will be used. The AMPHORA and placebo gels 
will be filled (5 g) into identical single-dose applicators consisting of an injection molded opaque 
white high-density polyethylene (HDPE) barrel with a rounded distal end for easy insertion. A 
thermoplastic rubber piston will be inserted at the opposite end of the barrel. This component 
will seal the end of the barrel to keep the contents stable over time and also functions as the 
applicator piston when in use. A HDPE plunger rod will be packaged alongside of the barrel 
within an aluminum overwrap. Product will be dispensed as a box of 10 overwrapped applicators 
with used applicator return bags and instructions for use.

4.1.2 Product Supply 
AMPHORA and placebo will be supplied by the Sponsor, Evofem, Inc., 12400 High Bluff 
Drive, Suite 600, San Diego, CA 92130. 
4.1.3 Product Storage, Stability, and Expiration  
The investigational product should be stored at room temperature (15oC-30oC). The 
investigational product will be maintained and dispensed by site research staff. 
4.1.4 Preparation 
The investigational product is supplied ready for use. No preparation is necessary. 
4.1.5 Distribution to Subjects/Return of Unused Product and Used Applicators 
Following screening, enrollment, and randomization, subjects will be issued a 4-week supply of 
investigational product based on the individual subject’s projected usage. Each investigational 
product box contains 10 applicators. A subject could receive up to three boxes at a study visit 
during the intervention period. Subjects will be asked how many prefilled applicators they need, 
based on their number of sexual encounters per 4 weeks. At Visits 2 to 4 each, during the 
intervention period, subjects will return all unused product and used applicators packaged 
individually in plastic return bags provided and will be issued a new 4-week supply of 
investigational product based on projected usage. Unopened kits may be redispensed to the same 
subject, as appropriate. Subjects may be issued additional investigational product, as needed, 
should their supply be exhausted prior to the next study visit; however, excessive product usage 
should be brought to the attention of the Investigator and Sponsor. At Visit 5, subjects will return 
all unused product and used applicators. 
4.1.6 Administration  
AMPHORA and placebo will be intravaginally administered by the subject in exactly the same 
manner. To administer, the plunger rod is inserted into the piston end of the barrel engaging the 
piston. The cap is removed from the distal end of the barrel; the barrel is then inserted into the 
subject’s vagina (distal end first). The plunger rod is pushed into the barrel, subsequently moving 
the piston and gel toward the open end of the barrel. Only the gel will leave the barrel.  
Detailed instructions for administration are included as Appendix C and supplied to the subject 
with the investigational product. Subjects will be trained in investigational product application 
prior to issuance.

the amount dispensed to study subjects, the amount returned from subjects at each visit (unused 
and used applicators) and the amount in inventory (not issued). These records should include the 
dates, quantities, and batch/serial numbers or kit numbers. 
 
The Investigator will record drug accountability on a Drug Disposition Log, which will be 
monitored and confirmed by the Clinical Research Associate (CRA). Upon completion of the 
study and final drug accountability monitoring visit, all unused study medication will be returned 
to Evofem, Inc., or, if instructed by Evofem, Inc., unused investigational product may be 
destroyed onsite according to the site’s standard operating procedures (SOPs).

Study Procedures/Evaluations 
Subjects will undergo the following study procedures as indicated in this section and according 
to the Schedule of Assessments (Table 1). All equipment used should be calibrated and undergo 
routine calibration, as appropriate.  
5.1 
Written Informed Consent 
A written informed consent will be obtained from all study participants before start of any study 
activities. The Informed Consent specifies, in lay and culturally appropriate language, all 
expectations from the participant including duration of study, number of doses and visits, 
procedures at each visit, safety documentation (including subject diary), use of contraceptives, 
restrictions on intravaginal product or device use, sampling plan, potential risks, stipend for 
participation in study, and relevant research scope.  
 
All study-related questions by the subject should be responded to before completion of the 
Informed Consent. The subject will be provided ample time to consider their potential 
participation, including time to consult with friends, family, and primary care provider if desired. 
The completed Informed Consent form will be verified for its proper completion. A signed copy 
of the Informed Consent will be provided to the subject and the original will be kept on file in 
the subject’s study file.  
5.2 
Inclusion/Exclusion Criteria 
Participants will meet all the stated inclusion criteria and not possess any of the exclusion criteria 
to be eligible to participate in this study. Only subjects that are eligible based on the study 
inclusion and exclusion criteria will be enrolled in the study.  
5.3 
Evaluation of Eligibility Criteria 
The Investigator will evaluate whether a subject meets the study’s inclusion/exclusion criteria at 
screening and enrollment and before administering any study product. The Investigator will be 
responsible for ensuring that the evaluation of eligibility criteria is addressed for all subjects 
enrolled in the study.  
5.4 
Demographics

5.5 
Clinical Evaluations 
All clinical procedures summarized in this section will be performed according to the site’s SOC 
SOPs.  
5.5.1 Medical History  
A detailed medical/surgical/gynecologic/sexual history will be obtained. Changes in medical 
history, if applicable, will be reviewed at each visit. 
A review of body systems will be performed by the Investigator to screen for exclusion criteria. 
Subjects will be asked about current drug and alcohol use by the Investigator for evaluating 
eligibility. 
5.5.2 Vital Signs  
Vital signs, including blood pressure, heart rate, and body temperature, will be measured and 
recorded. Vital sign measurements will be obtained after the subject has been sitting quietly for 
at least 5 minutes. When taking an oral temperature, assure the subject has not had any recent hot 
or cold beverages or has recently smoked, including e-cigarettes. The Investigator should use 
clinical judgment when characterizing bradycardia among health subjects, eg, conditioned 
athletes.  
5.5.3 Gynecologic Examinations  
A full gynecologic examination (speculum) will be performed after swab for vaginal pH is 
collected. 
Targeted physical and/or gynecologic examination (speculum), will be performed at any 
subsequent or unscheduled visit if necessary due to an AE.  
5.5.4 Concomitant Medications 
Concomitant medications that will be taken during the study, including all over-the-counter 
medications, vitamins, and nutritional supplements, will be recorded and should include at a 
minimum: start date, stop date or continuing, and indication/reason. 
5.5.5 Height and Weight  
Body weight and height will be recorded.

5.6 
Laboratory Evaluations  
Specimens collected for NAATs will be processed by the sites and shipped to a central 
laboratory for testing. All other laboratory testing and staining of used applicators will be 
performed onsite. 
5.6.1 Pregnancy Testing  
Subjects of reproductive potential, including those with history of tubal ligation, will be required 
to provide a urine specimen to be tested for uHCG. This test will be performed at each site using 
the SOC testing materials and procedure. 
Negative results must be obtained prior to dosing. Women who test positive for pregnancy will 
be excluded from participating in this study and be referred for follow-up as per clinic protocol 
(see Section 6.6.2 Pregnancy). 
5.6.2 Vaginal pH Testing 
Swab for vaginal pH reading is collected prior to introduction of speculum for gynecologic 
exam. Specimen collection and vaginal pH testing procedures is detailed in the Manual of 
Procedures (MOP). 
5.6.3 Nucleic Acid Amplification Tests for Chlamydia trachomatis/Neisseria gonorrhoeae 
All women will have vaginal swabs collected all visits (screening, enrollment, and each 
intervention visit and follow-up visit) for NAATs. Swabs will be collected by clinician when 
speculum exams are performed; otherwise vaginal swabs will be self-collected by subject while 
in clinic. Specimens will be collected using the specific collection/transport kit materials and 
package insert instructions as designated by the central laboratory. Specimens will be shipped to 
the central laboratory according to procedure and as included in the MOP. All positive results 
will be reported to the study site for follow-up. 
5.6.4 Staining of Used Applicators 
Sites will collect returned unused product and used applicators at each study visit. Site staff is 
responsible to visually inspect unused study product to confirm package seal is intact/not broken. 
If the seal is broken the applicator should be assessed for use (appears full of gel and unused). 
The used applicators will be tested onsite to validate vaginal insertion by using staining with 
trypan blue. Staff performing staining procedures will be trained and procedures will be detailed 
in the MOP.

Subject eDiaries 
Each subject will be provided with a secure validated eDiary software application downloaded to 
their personal cellular telephone or tablet to collect, at minimum, subject-reported sexual activity 
and study product use data. The eDiary application will be de-identified using the subject 
number assigned at the time of screening; research staff will receive, and review data identified 
only by the subject number throughout the course of the study.  
The Investigator or designee will ensure each subject is trained in the importance of the eDiary 
and on its use. The instruction on maintaining the eDiary should include fields that must be 
completed and how the subject should record data within them. All eDiary entries will be 
reviewed on a regular basis, with subjects at each follow-up visit. Study sites must encourage 
eDiary recording by subjects via text messaging or direct contact with subjects. All eDiary 
entries will become part of the subjects’ study record. 
5.8

Safety Reporting and Safety Monitoring 
Since this clinical study is being conducted exclusively in the US, FDA regulations including 
safety monitoring and reporting responsibilities of Sponsor and Investigators must be followed to 
ensure the safety and protection of human subjects and accuracy of the data collected. 
6.1 
Responsibilities 
Investigators participating in this clinical study are required to: 
• Evaluate subject safety including assessment of AEs for seriousness, severity, and 
causality 
• Notify the ICON GPHS Medical Monitor of SAEs within 24 hours of becoming 
aware of them 
• Provide detailed written reports, including necessary documentation requested by the 
Sponsor or IRB, promptly following immediate initial reports 
• Inform the IRB of AEs as required by applicable regulatory requirements 
6.2 
Definitions 
Adverse Event (AE)  
Any untoward medical occurrence in a clinical investigation subject who has received a study 
product intervention and that does not necessarily have to have a causal relationship with the 
study product. An AE can, therefore, be any unfavorable and unintended sign (including an 
abnormal laboratory finding, for example), symptom, or disease temporally associated with the 
use of a study medicinal product, whether or not considered related to the study medicinal 
product.  
Serious Adverse Event (SAE)  
An SAE is any adverse event that results in any of the following outcomes: 
• Death 
• Life-threatening (immediate risk of death) 
• Inpatient hospitalization or prolongation of existing hospitalization 
• Persistent or significant disability or incapacity 
• Congenital anomaly/birth defect 

AMPHORA® 
Protocol: EVO-003 
Evofem, Inc. v6.0 – 25 January 2019 
 
 
CONFIDENTIAL AND PROPRIETARY 
 
Page 41 of 76 
• Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered an SAE when, based upon appropriate medical 
judgment, they may jeopardize the subject and may require medical or surgical 
intervention to prevent one of the outcomes listed in this definition  
The term “life-threatening” in the definition of SAE refers to an event in which the subject was 
at risk of death at the time of the event. It does not refer to an event which hypothetically might 
have caused death if it were more severe. 
The term “hospitalization” describes a period of at least 24 hours. Overnight stay for observation, 
treatment at an emergency room or treatment on an outpatient basis does not constitute a 
hospitalization. However, medical judgment must always be exercised and when in doubt the 
case should be considered serious. 
Non-serious Adverse Event 
A non-serious AE is any AE which does not fulfill the definition of an SAE. 
Treatment-emergent Adverse Event (TEAE) 
A TEAE is any AE occurring after the application of the study product and within the time of 
residual product effect, or pre-existing medical condition that worsens in intensity after the 
application of study product and within the time of residual product effect. The time of residual 
product effect is 7 days after the dose of the study product, when the effect of the product is still 
considered to be present based on change of vaginal pH from baseline. 
Unexpected Adverse Reaction 
An adverse reaction, the nature or severity of which is not consistent with the applicable product 
information (eg, Investigational New Drug (IND) Safety Data; see Investigator’s Brochure). 
6.3 
Safety Reporting Requirements 
6.3.1 Reporting Interval 
All AEs and SAEs will be collected and recorded following randomization.  
The Investigators will follow all AEs that are deemed at least possibly related to investigational 
product and SAEs until resolution (return to pre-intervention status or stabilization of conditions 
deemed as chronic), even if this extends beyond the study-reporting period.

CONFIDENTIAL AND PROPRIETARY 
 
Page 42 of 76 
A subject will be considered as lost to follow-up if participation in AE assessment is not 
continued after: 
• Three unsuccessful attempts at telephone contact (separated by at least 24 hours) 
following missed AE assessment visit or telephone consultation; followed by 
• Issuance of a certified letter to last documented address of subject, and no response 
within 7 days of mailing 
At any time after the completion of the study, if an Investigator becomes aware of an SAE that is 
suspected to be related to the investigational product, the Investigator will report the event to 
ICON GPHS within 24 hours of awareness. The Investigator will ensure that the appropriate IRB 
has been notified of the reported SAE in a timely manner per internal IRB reporting 
requirements. 
6.3.2 Notification of the Sponsor of Serious Adverse Events 
Any AE that meets a protocol-defined serious criterion, must be submitted within 24 hours of 
site awareness. 
The Medical Monitor will review and assess the SAE for regulatory reporting and potential 
impact on study subject safety and protocol conduct. 
Other supporting documentation of the event requested by the Medical Monitor should be 
provided. 
The Sponsor will be notified of any unexpected SAE with suspicion of being related to study 
drug. In addition, the Sponsor will be informed of any study procedure-related SAE which may 
warrant a change of any study procedure or halting of the study. 
6.3.3 Regulatory Reporting for Studies Conducted Under Investigational New Drug 
Application 
The Sponsor is responsible to report both serious and unexpected events that are associated with 
investigational product(s) to the FDA within the required timelines as specified in 21 CFR 
312.32 (fatal and life-threatening events within 7 calendar days by phone or fax and all other 
SAEs in writing within 15 calendar days). All serious events designated as “not associated” to 
investigational product(s) will be reported to the FDA at least annually in a summary format.  
6.4 
Investigator’s Assessment of Adverse Events  
The determination of seriousness, severity, and causality will be made by a site Investigator.

CONFIDENTIAL AND PROPRIETARY 
 
Page 43 of 76 
6.4.1 Assessment of Severity 
Each AE will be assessed by the Investigator with regard to the following categories: 
Seriousness 
An SAE is defined as any untoward medical occurrence that at any dose: 
• 
Results in death 
• 
Is life-threatening; this means that the subject is at risk of death at the time of the event, 
and it does not mean that the event hypothetically might have caused death if it were 
more severe 
• 
Requires inpatient hospitalization or prolongation of existing hospitalization 
• 
Results in persistent or significant disability or incapacity 
• 
Is a congenital anomaly or birth defect 
• 
Is an important medical event that may not be immediately life-threatening or result in 
death or hospitalization but that may jeopardize the subject or require intervention to 
prevent one of the above outcomes; examples of such events are intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or convulsions 
that do not result in hospitalization, or development of drug dependency or drug abuse 
Medical and scientific judgment should be exercised in deciding whether a case is serious and 
whether expedited reporting is appropriate. 
 
Intensity 
Investigators should assess the severity of AEs according to Common Terminology Criteria for 
Adverse Events (CTCAE) version 4.03. In general, CTCAE severity grades are: 
• 
Grade 1: mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated 
• 
Grade 2: moderate; minimal, local, or noninvasive intervention indicated; limiting age-
appropriate instrumental activities of daily living (ADL) (instrumental ADL refer to 
preparing meals, shopping for groceries or clothes, using the telephone, managing 
money, etc) 
• 
Grade 3: severe or medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care 
ADL (self-care ADL refer to bathing, dressing and undressing, feeding self, using the 
toilet, taking medications, and not bedridden) 
• 
Grade 4: life-threatening consequences; urgent intervention indicated

Evofem, Inc. v6.0 – 25 January 2019 
 
 
CONFIDENTIAL AND PROPRIETARY 
 
Page 44 of 76 
• 
Grade 5: death related to AE 
 
Causality 
The Investigator will assess the causality/relationship between the study drug and the AE and 
record that assessment in the electronic data capture (EDC) system. The most likely cause of an 
AE (eg, concomitant disease, concomitant medication, other) will be indicated in the EDC 
system with details of the concomitant disease or medication or other cause. 
The causal relationship of the AE to study drug will be described per World Health Organization 
(WHO) Uppsala Monitoring Centre (UMC) causality categories:  
• Certain 
o Event or laboratory test abnormality, with plausible time relationship to drug intake 
o Cannot be explained by disease or other drugs 
o Response to withdrawal plausible (pharmacologically, pathologically) 
o Event definitive pharmacologically or phenomenologically (ie, an objective and 
specific medical disorder or a recognized pharmacological phenomenon) 
o Rechallenge satisfactory, if necessary 
• 
Probable/Likely:  
o Event or laboratory test abnormality, with reasonable time relationship to drug intake 
o Unlikely to be attributed to disease or other drugs 
o Response to withdrawal clinically reasonable 
o Rechallenge not required 
• 
Possible:  
o Event or laboratory test abnormality, with plausible time relationship to drug intake 
o Could also be explained by disease or other drugs 
o Information on drug withdrawal may be lacking or unclear 
• 
Unlikely: 
o Event or laboratory test abnormality, with a time to drug intake that makes a 
relationship improbable (but not impossible) 
o Disease or other drugs provide plausible explanations 
• 
Conditional/Unclassified: 
o Event or laboratory test abnormality 
o More data for proper assessment needed, or 
o Additional data under examination

• 
Unassessable/Unclassifiable: 
o Report suggesting an adverse reaction 
o Cannot be judged because information is insufficient or contradictory 
o Data cannot be supplemented or verified 
6.4.2 Adverse Event Outcome Measures 
The outcome of all AEs will be reported based on the following definitions, independent of 
whether they are serious or non-serious AEs, their severity, or their relationship to the 
investigational product:  
• Recovered: fully recovered, or by medical or surgical treatment the condition has 
returned to the level observed at the first study-related activity after the subject signed the 
informed consent 
• Recovering: the condition is improving and the subject is expected to recover from the 
event. This term should only be used when the subject has completed the study 
• Recovered with sequelae: as a result of the AE, the subject suffered persistent and 
significant disability/incapacity (eg, became blind, deaf, paralyzed). Any AE recovered 
with sequelae should be rated as an SAE 
• Not recovered 
• Fatal 
• Unknown: this term should only be used in cases where the subject is lost to follow-up 
6.5 
Study-related Adverse Events 
See Appendix A for descriptions and grading criteria for anticipated study-related AEs. All AEs 
will be documented on the standard AE forms. AE forms for cutaneous AE grade 3 or higher will 
be sent to the Medical Monitor within 24 hours of awareness (non-serious or serious).    
The reporting of an AE grade 3 or higher will prompt follow-up diagnostic work-up (eg, physical 
examinations, vital signs, descriptive assessment, subject diary, and clinical laboratory work). If 
the cutaneous AE is grade 3, subjects will be seen twice weekly until the severity is reduced to 
grade 2 or less at two consecutive follow-up visits (1 week) and not getting worse.  
6.6 
Other Safety Considerations 
Any significant worsening or new findings noted during post-intervention follow-up visit or any 
other potential safety assessments performed during the study, whether or not they are required 
by the protocol, should be recorded on the appropriate AE form.

6.6.1 Follow-up of Adverse Events 
During and following a subject’s participation in a clinical study, the Investigator should ensure 
that adequate medical care is provided to the subject for any AEs, including clinically significant 
laboratory values related to the study. The Investigator should inform the subject when medical 
care is needed for AEs. 
The period for reporting new AEs will continue until the post-intervention follow-up visit (final 
study visit).  
All non-serious AEs classified as possibly/probably related to the investigational product must be 
followed until the subject has recovered and all queries have been resolved. However, cases of 
chronic conditions can be closed if determined by clinician as stable, with an outcome of 
“recovering” or “not recovered.” If a subject died from another event, these cases can be closed 
with an outcome of “not recovered.” 
All other non-serious AEs must be followed until the outcome of the event is “recovering” (for 
chronic conditions), or until the end of the post-intervention follow-up stated in the protocol, 
whichever comes first, and until all queries related to these AEs have been resolved. If a subject 
died from another event, these cases can be closed with an outcome of “not recovered.” 
The Investigator must enter follow-up information about non-serious AEs on the AE form within 
the CRF. 
Queries or follow-up requests from ICON GPHS should be responded to within 14 calendar 
days, unless otherwise specified. The Investigator must forward follow-up information on SAEs 
to the requestor within 5 calendar days of obtaining the request for follow-up information. 
All SAEs must be followed until the outcome of the event is recovered, recovered with sequelae, 
or fatal and until all queries have been resolved. For cases of chronic conditions and cancer or if 
the subject dies from another event, follow-up until the outcome categories are “recovered,” 
“recovered with sequelae,” or “fatal” is not required, as these cases can be closed with an 
outcome of “recovering” or “not recovered.” 
6.6.2 Pregnancy 
While women of childbearing potential are eligible for the study, they must agree to use an 
approved form of birth control (see Section 3.1 Inclusion Criteria) over the duration of the study 
period. Women of childbearing potential are defined as any female who has experienced 
menarche and who is NOT permanently sterile or postmenopausal. Postmenopausal is defined as 
12 consecutive months with no menses without an alternative medical cause. If there is any

question that a subject will not be reliable in the adherence to this requirement, they should not 
be entered into the study. 
Study subjects must be instructed to notify the study site Investigator immediately if they suspect 
pregnancy during the course of the study and for a period of 4 weeks following study discharge. 
Subjects who become pregnant will be instructed to immediately discontinue study product. The 
Investigator must report any pregnancy during the study to the Medical Monitor within 14 
calendar days of obtaining the information using the Pregnancy Form and the Pregnancy 
Follow-up Form, respectively. Pregnancy complications must be recorded as AEs or SAEs if 
meets criteria. If the infant has a congenital anomaly or birth defect, the anomaly or defect must 
be reported and followed as an SAE.

Clinical Monitoring/Site Monitoring Plan  
Monitoring will be conducted to ensure that human subject rights and well-being are protected, 
data are accurate, complete, and verifiable from source documents, and the study complies with 
the protocol/amendment(s), and applicable regulatory requirements.  
In order to ensure protocol compliance, monitoring visits will occur at scheduled intervals prior 
to, during, and at study completion. The visit frequency will be defined in a monitoring plan and 
communicated to the Investigators. 
A separate study-specific monitoring plan will define the monitoring details such as the 
frequency of monitoring visits and percentage and selection of charts/source documentation to be 
monitored. An ICON GPHS CRA will be responsible for the clinical monitoring at the study 
sites. The CRA will operate independently from the study sites and will comply with ICON 
GPHS SOPs. The CRA will ensure that the Investigators understand the investigational status of 
the study product, all requirements of the protocol, and his/her regulatory responsibilities as an 
Investigator. The CRA will visit the clinical site in accordance with the monitoring plan to assess 
compliance with the protocol, verify accuracy and completeness of the data, perform 
accountability of study product, and review essential regulatory documents. 
The investigational sites will provide direct access to all study-related documents and records 
maintained by the Investigators, including but not limited to study-related source data for the 
participants in this study.  
The Investigators are ultimately responsible for ensuring that the CRA’s findings are addressed.

Statistical Considerations 
This section outlines the basic statistical approach for the study. A final statistical analysis plan 
will be written and approved before the database lock. This plan will specify all statistical 
methods and plans for analysis.  
8.1 
Study Hypotheses 
The hypothesis to be tested in this study is that AMPHORA will prevent the sexual transmission 
of CT. As noted above, CT infection in women is associated with higher vaginal pH (pH >4.5) 
(10). This finding is supported by other reports in the literature (7). In addition, a higher vaginal 
pH has been associated with increased transmission of GC (28). AMPHORA also contains a 
relatively high concentration of lactic acid (1.8% w/v). Lactobacilli inactivate CT through the 
production of lactic acid (29). Thus, AMPHORA should reinforce the ability of lactobacilli to 
maintain healthy levels as well as provide additional lactic acid that may act directly in 
preventing CT infection. 
8.2 
Sample Size Considerations 
The primary analysis is a comparison between proportion of subjects who experience at least one 
CT infection among the intervention groups (AMPHORA or placebo).  
It is assumed that the proportion of subjects experiencing at least one infection of CT during the 
study period (incident infection of CT) up to Week 16 under placebo will be 22.5%. An incident 
infection of CT of 13% in the subjects receiving active treatment (ie, a treatment difference of 
9.5%) is considered clinically relevant for AMPHORA versus placebo. Using a Chi-square test 
for the primary endpoint, 253 analyzable subjects per treatment group (506 subjects total in the 
ITT population) will yield approximately 80% power to detect 9.5% treatment difference with a 
2-sided 5% type I error rate (SAS 9.3 PROC POWER). Assuming that 20% of the total enrolled 
subjects will be lost to follow-up, 15% will be re-infected with GC (making them ineligible for 
the primary endpoint analysis), and 5% will be deemed ineligible for analysis due to antibiotic 
use, the total sample size planned for this study is 844 subjects.  
8.3 
Final Analysis Plan 
8.3.1 Analysis Populations 
This study will utilize three analysis populations: Intention-to-Treat (ITT), modified Intention-to-
Treat (mITT), and safety. 
The ITT population will consist of all randomized subjects. The mITT population will consist of 
all randomized subjects who are negative for chlamydia and gonorrhea at enrollment and report 

AMPHORA® 
Protocol: EVO-003 
Evofem, Inc. v6.0 – 25 January 2019

Page 50 of 76 
use of study product prior to at least one coital event. Lastly, the safety population will be based 
on subjects who applied any amount of study product. 
Analyses using the ITT and mITT populations will be performed based on the treatment 
randomized. Meanwhile, safety analyses will be based on the treatment received.  
8.3.2 Randomization and Stratification 
A randomized study group assignment schema, stratified by study site, will be developed using 
SAS, release 9.3 or higher. 
8.3.3 Procedures for Handling Missing, Unused, and Spurious Data 
All analyses will be based on data as observed in the study. No imputations will be performed for 
data that are missing or spurious. 
Given the need to provide treatment to subjects who become infected with CT and/or GC, not all 
subjects will be evaluable for each endpoint since the use of antibiotics would treat both possible 
infections. Therefore, the subjects analyzed for the primary efficacy endpoint are those that are 
infected with CT or who complete the study with no re-infections. Likewise, the subjects 
analyzed for the secondary efficacy endpoint are those that are infected with GC or who 
complete the study with no re-infections. 
8.3.4 General Statistical Considerations 
All subjects that enter the study will be accounted for in the final clinical report, whether or not 
they are included in the analysis. All reasons for exclusion will be documented for those 
subjects. 
For continuous variables, descriptive statistics will include the number of non-missing values, 
mean, standard deviation, median, minimum, and maximum. For categorical variables, 
descriptive statistics will include counts and percentages per category. 
Baseline values for all parameters will be the most recent value prior to administration of study 
product or speculum exam. 
8.4 
Planned Statistical Methodology 
8.4.1 Data Analysis for Efficacy 
For the primary analysis, the proportion of subjects who experience at least one CT infection will 
be compared between the intervention groups (AMPHORA or placebo) using a Chi-square test. 

AMPHORA® 
Protocol: EVO-003 
Evofem, Inc. v6.0 – 25 January 2019 
 
 
CONFIDENTIAL AND PROPRIETARY 
 
Page 51 of 76 
The primary efficacy analysis will be completed using the subjects deemed analyzable (see 
Section 8.2) from the mITT population.  
The primary statistical hypothesis being tested is that there is no difference in the proportion of 
subjects with CT infections in the AMPHORA intervention group versus placebo. In statistical 
terms:  
H0: pAMPHORA = pplacebo, HA: pAMPHORA ≠ pplacebo 
 
where pAMPHORA and pplacebo denote the proportion of subjects with CT infections during the 
study while on AMPHORA or placebo, respectively. Denominators for percentages are number 
of subjects in the mITT population in each intervention group. To test superiority over placebo, 
the incident infection of CT will be compared against placebo based on a Chi-square test. The 
estimated difference in proportions, 95% confidence interval, and p-value will be presented. A 
two-sided 5% type I error rate (α=0.05) will be used. 
Similar analyses will be performed for incident infection of GC.  
8.4.2 Data Analysis for Safety  
All AEs will be coded using the Medical Dictionary for Regulatory Activities® (MedDRA) v17.0 
or higher. The incidence of AEs (new or worsened) will be summarized by primary system organ 
class, preferred term, severity, and relationship to study intervention. The incidence of death, 
SAEs, and AEs leading to discontinuation will be summarized separately by primary system 
organ class and preferred term.  
8.4.3 Analyses for Exploratory Objectives and Endpoints 
Adherence with AMPHORA usage during study (rate of product use adherence) will be 
measured by inspection/analysis of returned gel applicators and eDiary data. Summary statistics 
of adherence overall and by intervention group will be provided.  
Based on the adherence rate for each subject, sensitivity analyses will be conducted in the same 
manner as the primary and secondary endpoint analyses to examine if the level of re-infection 
between treatment groups differs for ≥20%, ≥40%, ≥60%, ≥80%, and 100% adherence rates. 
These sensitivity analyses will be performed on the mITT population. 
Subject satisfaction with the study drug (including sexual satisfaction in Appendix E) will be 
summarized using frequency and percentage.  
Subject sexual satisfaction will be measured utilizing baseline and follow-up questions on the 
impact of study drug on sexual function with the SFQ and item 10 on the FSFI. These scores and 
responses will be summarized using frequency and percentage.

Data Handling/Recordkeeping/Source Documents 
It is each Investigator’s responsibility to ensure that all team members appropriately handle all 
data and related documentation. All subject information, including source documents and 
laboratory reports, must be reviewed by the Investigator and clinical team and submitted to the 
ICON GPHS Data Management Team via eCRF. ICON GPHS Data Management will work with 
the Investigators and CRAs to develop a data management plan, including eCRF creation and 
instructions for the study to establish, maintain, and update the study data effectively. Clinical 
data will be entered directly from the source documents to the data management system within 
72 hours of study activity to maintain up-to-date information on all clinical and laboratory data. 
There will be ongoing processing of data and quality checks. CRAs will be responsible for 
source verification of the eCRFs.  
Data security is of paramount concern. A comprehensive IT Systems Security Plan with a 
disaster recovery plan is in place to safeguard data systems related to this clinical study. 
9.1 
Data Capture Methods 
Clinical data (including AEs and concomitant medications) will be entered into the Clinical 
Studio EDC system. This system is a 21 CFR 11-compliant internet data entry system provided 
by the ICON GPHS Data Coordinating Center. Only those who are trained and delegated the 
responsibility by the Investigator (with delegation documented on the signature delegation log) 
will collect and enter data. The data system includes password protection and internal quality 
checks, such as heuristic checks, to identify data that appear inconsistent, incomplete, or 
inaccurate.  
9.2 
Types of Data 
Data for this study will include reported symptoms, AEs, clinical laboratory data, adherence with 
AMPHORA usage from eDiary data and applicator staining, and clinician-obtained baseline pH 
values.  
Clinical data will be entered directly from the source documents. CRAs will perform source 
verification and query generation. CRAs will work with the Data Manager and site personnel to 
freeze data prior to analysis. AEs, medical history, and medications will be coded using 
MedDRA v17.0 (or higher) and WHO drug dictionaries.  
9.3 
Study Records Retention  
Each study site will maintain appropriate medical and research records for this study, in 
compliance with ICH E6 R1 Section 4.9, regulatory and institutional requirements for the 

AMPHORA®

protection of confidentiality of subjects. The study site will permit authorized representatives of 
Evofem, Inc., ICON GPHS, and regulatory agencies to examine (and when required by 
applicable law, copy) clinical records for the purposes of clinical site monitoring, quality 
assurance reviews, audits, and evaluation of the study safety and progress. A site master file will 
be maintained to include essential documents.  
Study documents will be retained for a minimum of two years after the last marketing 
application approval or two years from the formal discontinuation of clinical development of the 
investigational product. These documents will be retained for a longer period, if required by local 
regulations. No record will be destroyed without the written consent of Evofem, Inc. 
9.4 
Source Documents 
The source document is defined as the first place the data are recorded, eg, hard copy paper 
and/or electronic forms, laboratory printouts, and medical records. The study sites may use 
study-specific paper data collection forms that mirror each EDC form to enter data from the 
source (the subject’s chart, eDiary data, or other medical records) onto the form provided. 
Clinical and research laboratory reports will be printed from the laboratory system and utilized as 
source documents. Clinical data will be entered directly from the source documents to the data 
management system within 72 hours of study activity to maintain up-to-date information on all 
clinical and laboratory data protocol deviations. 
9.5 
Protocol Deviations 
A protocol deviation is any noncompliance with the clinical study protocol or GCP requirements. 
The noncompliance may be either on the part of the subject, the Investigator, or the study site 
staff. As a result of deviations, corrective actions are to be developed by the site and 
implemented promptly.  
Investigation of the protocol deviations will be conducted by the study team, especially the 
Investigator, to assess whether the deviation is due to a subject-specific issue, or whether there is 
an underlying structural or operational aspect of the research process and protocol which may 
require correction or revision. 
It is the responsibility of the Investigator to use continuous vigilance to identify and report 
deviations by entering the information into the clinical database within three working days of 
identification of the protocol deviation or of the scheduled protocol-required activity. 
Appropriate reporting forms must be maintained in the regulatory file as well as in the subject’s 
source document. The Investigator is responsible for ensuring all study staff understand the IRB 
reporting guidelines and adhere to all related requirements and documentation. A cumulative list 
of protocol deviations will be reported in the clinical study report. 
Refer also to Section 10 Quality Control and Quality Assurance.

Quality Control and Quality Assurance 
The Clinical Quality Management Plan (CQMP) is developed by ICON GPHS. The CQMP 
outlines quality control (QC) and quality assurance (QA) processes to be applied to protocol 
activities at the clinical sites.  
The ICON GPHS QA Specialist will develop, implement, and oversee all functions of the 
CQMP. The Investigators are responsible for the oversight and implementation of the CQMP at 
their respective clinical sites. The site roles and responsibilities are to submit protocol deviation 
logs, AE/SAEs, and screening and enrollment logs within required time intervals. 
The QC of study-related records will be performed by the site’s clinical staff. Prior to data entry, 
study visit documentation will be reviewed for accuracy and completeness.  
Through periodic verification of data collected for this protocol, ICON GPHS QA activities 
document compliance with GCP standards, human subjects’ protections, and applicable federal 
regulations governing the use of investigational products. Key quality indicators, as detailed in 
the CQMP and applicable to the protocol, will be examined in each subject record selected for 
QA review.  
Study records will remain onsite in a secure location. The clinical site will permit ICON GPHS, 
the Sponsor, and other applicable regulatory authorities access to study-related records.

Appendices 
Appendix A. Grading of Study-related Adverse Events 
The table referenced below is a modification of the NCI Common Terminology Criteria for 
Adverse Events (v4.03, May 2009) tables, adjusted to display common AEs applicable to this 
study. A grading (severity) scale is provided for each AE term. A brief definition is provided to 
clarify the meaning of each AE term. Any clinical event deemed by the clinician to be serious or 
life threatening should be considered a Grade 4 event.  
A semi-colon indicates ‘or’ within the description of the grade; a single dash (-) indicates a grade 
is not available. ADL = Activities of Daily Living. 
ESTIMATING SEVERITY GRADE 
For abnormalities NOT found elsewhere in the tables use the scale below to estimate grade of 
severity: 
GRADE 1 
Mild; asymptomatic or mild symptoms; clinical or diagnostic observations 
only; intervention not indicated 
GRADE 2 
Moderate; minimal, local or noninvasive intervention indicated; limiting age-
appropriate instrumental ADL*. 
GRADE 3 
Severe or medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; limiting 
self-care ADL**. 
GRADE 4 
Life-threatening consequences; urgent intervention indicated. 
GRADE 5 
(Death) is not appropriate for some AEs and therefore is not an option. 
*Instrumental ADL refer to preparing meals, shopping for groceries or clothes, using the 
telephone, managing money, etc. 
**Self-care ADL refer to bathing, dressing and undressing, feeding self, using the toilet, taking 
medications, and not bedridden.

How to Use the Study Drug 
 
Description 
• 
Each single-use foil pouch contains a pre-filled applicator with a pink cap and a 
plunger rod (Figure 1). 
 
Important Use Information 
• 
During your entire time in this study, use the Study Drug every time you have 
vaginal sex regardless of the time of the last application or even if you have sex more 
than once in a day. The Study Drug can be used immediately before or up to one 
hour before vaginal sex. 
• 
If you or your partner develop burning or irritation of the vagina or penis or 
experience difficult or painful urination, discontinue use and consult your clinical site 
staff. 
 
Instructions for Using the Study Drug 
1. 
• 
Wash your hands with soap and water before opening the foil pouch. 
• 
Remove the pre-filled applicator and plunger from the foil pouch. 
 
2. Gently insert the pointed end of the plunger into the opening inside the pre-filled applicator 
until the plunger lightly snaps in place (Figure 2). Be careful not to push the plunger farther 
after it snaps in place to avoid the release of any Study Drug into the cap.

3. 
• 
Remove the pink cap from the pre-filled applicator (Figure 3). The pre-filled 
applicator is now ready for use. 
• 
NOTE – space between the Study Drug and end of the applicator is normal. 
 
 
 
4. 
• 
Hold the applicator at the grooved area closest to the plunger. Gently place the 
applicator into the opening of your vagina pushing it as far as it will comfortably go, 
similar to the placement of a tampon (Figure 4). 
• 
NOTE - Lying on your back with your knees up may help with this step. 
 
 
5. Using your index finger, push the plunger all the way into the barrel of the pre-filled 
applicator until it stops to ensure all the Study Drug has been applied (Figure 5).

6. 
• Gently withdraw the pre-filled applicator (Figure 6). Do not reuse the empty applicator 
or plunger. Place the used applicator in the resealable plastic bag provided (only one 
applicator per bag) and return along with all other used and unused applicators to next 
scheduled visit. 
• The Study Drug gel is effective immediately after insertion. Vaginal sex should occur 
within one hour after insertion.
