Duration of the study:   
Overall treatment duration is thirteen 28-day cycles, i.e. 12 months. 
Those subjects who discontinue due to a pregnancy wish will be followed-up for a maximum 
of one year after study discontinuation for return of spontaneous menstruation and until 
pregnancy or initiation of a contraceptive method (whichever occurs first). 
Statistical Methods: 
For the efficacy analyses, the pregnancy rates will be expressed as: 
- 
Pearl Index (number of pregnancies per 100 woman years due to method and user 
failure) with a two-sided 95% confidence interval (CI); 
- 
Method failure Pearl Index (number of pregnancies per 100 woman years due to 
method failure only) with a two-sided 95% CI; 
- 
Life-table analysis (cumulative pregnancy rate). 
For Pearl index calculations, thirteen 28-day cycles constitute one woman year. 
 
Primary Efficacy Analysis:  
Pearl Index for subjects aged 18 to 35 years, inclusive, at the time of screening. 
 
Secondary Efficacy Analyses: 
1. Method failure Pearl Index and life-table analysis for subjects aged 18 to 35 years, 
inclusive, at the time of screening. 
2. Pearl Index, method failure Pearl Index and life-table analysis for the overall study 
population (18 to 50 years). 
 
Additional Summaries: 
1. Occurrence of scheduled and unscheduled vaginal bleeding/spotting in the overall 
study population. 
2. Compliance analysis based on tablet intake in the overall study population. 
3. Number, frequency, type and intensity of AEs and SAEs in the overall study 
population. 
4. Endometrial histological changes in the subjects included in the endometrial safety 
Substudy. 
5. Descriptive summaries for other safety parameters including clinical labs, physical 
exams, gynecological exams, and vital signs. 
6. Descriptive summaries of scores of well-being questionnaires. 
 
Continuous variables will be summarized using descriptive statistics (mean, median, 25th 
percentile, 75th percentile, standard deviation (SD), standard error of the mean (SEM), 
minimum, maximum, and number of subjects) and all categorical variables will be

Birth control methods which physically block or otherwise 
prevent sperm from entering the uterus and reaching the egg 
for fertilization, including spermicides, sponges, condoms, 
diaphragms, and cervical caps. 
 
Pre-treatment pregnancy 
Pre-treatment pregnancies are pregnancies with an estimated 
date of conception before the first intake of trial medication. 
On-treatment pregnancy 
On-treatment pregnancies are pregnancies with an estimated 
date of conception within the in-treatment period i.e. Day 1 to 
2 days after the last intake of investigational product (whether

INTRODUCTION 
7.1 Background 
Combined oral contraceptives (COCs) are medications taken orally combining a progestin and 
an estrogen. The function of the progestin is to inhibit ovulation by a central feedback 
mechanism resulting in decreased luteinizing hormone (LH) secretion by the pituitary gland.  
The estrogen component also contributes to contraceptive activity by inhibiting the secretion 
of follicle-stimulating hormone (FSH) but its major function is to provide stability to the 
endometrium and consequently to provide acceptable cycle control and bleeding pattern.  
COCs are widely used in the industrialized world.  They have been shown to be highly effective 
in terms of contraception.  
The potent synthetic estrogen, ethinylestradiol (EE), is the most frequently used estrogen in 
COCs. EE is easily absorbed when administered orally. Products containing EE generally have 
a good bleeding profile; however EE is also responsible for most of the side effects experienced 
by COC users. Among those, a rare but potentially very serious event is venous 
thromboembolism (VTE). The increased risk of thromboembolism among COC users is 
principally due to the strong impact of EE on hepatic synthesis functions, which leads to an 
increased production of several proteins involved in the coagulation and inflammatory 
pathways. As a consequence, an imbalance appears between pro- and anticoagulant circulating 
factors in favor to pro-coagulation. Beside the thromboembolism risk, EE is also associated 
with water retention (responsible of breast tension, edema, weight increase, nausea, headache 
and liability of humor) as well as with an increased risk of cholangiopathy.  
To improve the safety profile of COCs, research and development has focused on two main 
approaches. First, the dose of EE has been progressively lowered from > 75 µg to as low as 
10 µg. As EE doses decrease, the incidence of irregular and potentially unacceptable bleeding 
profiles increases. The second approach has been to replace EE with a naturally occurring 
estrogen: new COCs containing estradiol (E2) or estradiol valerate (E2V) have recently been 
developed, with the prospect of decreasing the metabolic impact from the estrogen component 
of COCs.   
Estetra SPRL is developing a new COC containing a synthetic form of natural estrogen, estetrol 
(E4), in association with drospirenone (DRSP), a well-characterized and widely used 
contraceptive progestin. E4 is only produced by the human fetal liver during pregnancy and 
reaches the maternal circulation through the placenta. E4 has been isolated in maternal urine 
as early as week 9 of gestation. At term, the hormone is found at relatively high concentrations 
(about 1 ng/mL) in maternal plasma and over ten times higher in fetal plasma.

7.2 Prior Clinical Experience 
Estetrol  
In two Phase 1 clinical studies (PR3050 and PR3054) performed in healthy postmenopausal 
women, E4 was associated with a good safety and tolerability profile when it was taken orally 
as a single dose up to 100 mg and as daily multiple doses up to 40 mg during 28 consecutive 
days. Oral intake of multiple rising doses of E4 demonstrated an anti-gonadotropic activity 
characterized by a dose-dependent decrease in both FSH and LH levels. This study also 
documented a significant increase in endometrial thickness in accordance with E4’s estrogenic 
actions.  
Estetrol/Drospirenone 
The safety and efficacy of E4 in combination with DRSP were studied in healthy 
premenopausal women enrolled in two Phase 2 clinical studies called ES-C01 and ES-C02. 
Data from ES-C01 showed that 5 or 10 mg E4 combined with 3 mg DRSP administered in a 
24/4-day regimen for three treatment cycles exert a complete inhibition of ovulation1. Ovarian 
activity decreases with increasing dose of E4. In addition, very limited to no impact on hepatic 
metabolism was observed with the E4/DRSP combinations as demonstrated by measurement 
before and after three treatment cycles of triglycerides2 and surrogate markers of hemostasis 
such as D-dimer, Prothrombin fragment 1+2, inhibitors of coagulation (Active Protein C 
[APC] sensitivity, antithrombin III, APC resistance, protein S activity), liver factors 
(fibrinogen and prothrombin), endothelial factors (E-selectin and tissue-type plasminogen 
activator [tPA]) and carrier proteins (corticosteroid binding globulin [CBG], sex hormone 
binding globulin [SHBG] and ceruloplasmin)2. Decrease from baseline in the carrier proteins 
was noted after one cycle of treatment. These findings suggest limited impact of the E4/DRSP 
combination on the coagulation pathway.  
The combination of 3 mg DRSP with either 15 mg E4 or 20 mg E4 administered in a 24/4-day 
regimen was evaluated in the ES-C02 study, a six-cycle treatment study focusing on vaginal 
bleeding pattern and cycle control. A high rate of expected withdrawal bleeding (96.5%) and 
a low incidence of unscheduled bleeding/spotting episodes (16.9%) were observed with the 
15 mg E4/3 mg DRSP combination. In addition, the E4/DRSP combinations demonstrated a 
good safety and tolerability profile. A low frequency of adverse events (AEs) with the 15 mg 
E4/3 mg DRSP combination was recorded and all AEs were similar to those classically 
observed with COCs. Finally, no ovulations were observed during this study demonstrating 
the potential for high contraceptive reliability of the E4/DRSP combinations studied. 
From the different studies performed thus far with E4, it can be concluded that a E4-containing 
COC is well tolerated. No safety concern was observed with any E4 combination. However, 
until further evaluation in larger populations, the classical COCs’contraindications will apply 
to the 15 mg E4/3 mg DRSP combination.

Based on the results obtained from the Phase 2 studies, the regimen of 15 mg E4 combined 
with 3 mg DRSP was selected as the optimal combination (minimum effective dose) for the 
Phase 3 program.

INVESTIGATIONAL PLAN 
9.1 
Overall Study Design and Plan 
This study is a multicenter, open-label, single-arm study. 
The total duration of the study, including the screening, will range from 382 to 447 days for 
the participating subjects, which is approximately a year and one month. Those subjects who 
discontinue due to a pregnancy wish will be followed-up for a maximum of one year after 
study discontinuation for return of spontaneous menstruation and until pregnancy or initiation 
of a contraceptive method (whichever occurs first).  
Approximately 1550 healthy female subjects at risk for pregnancy, between 18 and 50 years 
old (inclusive, at the time of screening), and requesting contraception will be enrolled in the 
study. In total 1350 subjects will be 18 to 35 years old (inclusive). Recruitment may be stopped 
when 1550 subjects have been enrolled if the required number of subjects for the primary 
analysis (1350 subjects in the age group up to 35 years) has been reached. Recruitment in the 
age group > 35 years will be stopped when 200 subjects have been enrolled. 
Eligible subjects will be treated with 15 mg E4/3 mg DRSP for 13 consecutive cycles. The 
treatment must be taken once daily at approximately the same time of the day in a 24/4-day 
regimen, i.e. 24 active tablets followed by 4 placebo tablets (4-day hormone free interval). 
The primary objective of the study is to evaluate the contraceptive efficacy of the new COC, 
using the Pearl Index calculation (which reflects the pregnancy rate associated with a 
contraceptive method) among the subjects aged 18 to 35 years inclusive.  
The contraceptive efficacy will also be evaluated using the method failure Pearl Index (which 
reflects the pregnancy rate due to method failure only) and life-table analysis in the subjects 
aged 18 to 35 years inclusive and in the overall study population. 
The general safety will be evaluated by the determination of routine laboratory parameters, 
vital signs, by performing physical, gynecological and breast examinations and by recording 
number, frequency, type and intensity of AEs and serious adverse events (SAEs).  
Participating subjects will be asked to record daily in a subject diary their bleeding/spotting 
episodes. This will allow evaluating the bleeding pattern and the cycle control associated with 
the investigational product. 
Treatment compliance will be assessed using data from the subject diary across the entire study 
and by cycle. The subject diary will also be used to determine whether or not a cycle is at risk 
for the Pearl Index calculation. 
Physical, psychological and social functioning and well-being associated with the 
investigational product will be assessed with well-established questionnaires. A study schedule

of events is provided in Appendix 1. Details and descriptions of study procedures are contained 
in the following sections. 
9.2 
Rationale for Study Design 
The design of this study is in line with the final minutes of the Advisory Committee for 
Reproductive Health Drugs meeting (FDA) 3 held on January 23 and 24, 2007, the 
recommendations made by Kapp et al. 4 and the requirements of the European Medicines 
Agency (EMA) and the EMEA/CPMP/EWP/519/98 Rev 1 Guideline on Clinical Investigation 
of Steroid Contraceptives in Women 5 which states that: 
- 
Studies including an active comparator are not generally requested for efficacy 
purposes; 
- 
The duration of efficacy studies should be six months to one year or more;  
- 
For any new contraceptive, at least 400 women should have completed one year of 
treatment. 
This study is a multicenter, open-label, single-arm study which will allow quantification of the 
efficacy of the investigational product by calculating the pregnancy rate. The size of the study 
is also adequate to allow an assessment of the general safety and bleeding profile associated 
with the investigational product. 
The study design was discussed with FDA during end of phase 2 meeting as well as EMA 
during scientific advice (EMA/CHMP/SAWP/629721/2012). 
9.3 
Selection of Study Population

9.4.1.2 
Storage and Drug Accountability 
The Investigator will be responsible for the suitable storage of the investigational product in 
compliance with the storage instructions and must restrict access to the study personnel only. 
Under no circumstances will the Investigator allow the investigational products to be used 
other than as directed by this protocol.  The investigational product must be protected from 
unauthorized access (e.g. in a locked storage facility). Appropriate storage conditions at the 
site must be ensured either by controlled room temperature or by completion of a temperature 
log in accordance with local requirements and storage instructions on a regular basis, showing 
minimum and maximum temperatures reached over the time interval.  The Principal 
Investigator will have overall responsibility for the use of the investigational product at the 
site. The Principal Investigator or Designee will confirm receipt of the investigational product 
and will verify the contents of the shipment, using an interactive web response system (IWRS) 
upon receipt of the product. The Investigator or Designee shall maintain accurate 
investigational product inventory records, including the quantities and date of receipt of 
supplies from the Sponsor, and the quantities and dates of dispensing to each study subject. 
Shipping and handling of all investigational products will be conform to ICH-GCP guidelines, 
GMP and Local regulatory guidelines.    
At Visits 3, 4, 5, and 6, the Investigator should collect the investigational product (unused and 
empty) including spare blister if used (even if partially used) of the completed treatment cycles 
for drug accountability. Unused spare blister will be left for the subject. Used spare blisters 
will be replaced by a new spare blister. At Visit 7, the Investigator should collect all unused 
investigational product including spare blister (used or not), empty blisters for final drug 
accountability. 
At completion of the study, to satisfy regulatory requirements regarding drug accountability, 
all investigational products will be stored, inventoried, reconciled, and destroyed or returned 
to the Sponsor according to applicable regulations.  A written explanation must be provided 
for any discrepancies. The study monitor must review all records of drug accountability prior 
to the return or destruction of any supplies. 
This drug accountability log must be available for inspection during an audit (e.g., by Sponsor 
or a regulatory agency).  At the conclusion of the study, the Investigator must provide a copy 
of this record to the Sponsor. 
9.4.2 
Method of Assigning Subjects to Treatment 
This is a 1-treatment arm open-label study.  The subject will undergo screening where 
pretreatment clinical evaluations and specific procedures will be completed at the Screening 
Visit. Authorized site personnel will acknowledge that the subject met all of the specified 
inclusion criteria and none of the exclusion criteria before subject enrolment. 
At enrollment visit, after IWRS contact, investigational product packs labeled with study 
information will be assigned to the subject.

9.4.3 
Treatment Compliance 
Treatment compliance for the investigational product will be assessed based on the response 
values entered by the subject in the diary on a daily basis (see Section 9.6.1). A comparison 
will be made between the number of tablets expected to be used, based on the total number of 
treatment days, and the number of tablets taken according to the subject’s diary.  
In addition, the data will be used to identify when a pill has been missed.  
At each visit, the diary entries will be compared to the returned tablets to ensure consistency 
but the diary data will be used for compliance assessment. In case of discrepancy between the 
diary data and the returned tablets, the investigator will discuss with the subject and document 
this in the source data.  
9.4.4 
Selection of Doses and Timing of Administration in the Study 
The daily dose used in this study, i.e. 15 mg E4 and 3 mg DRSP, has been selected on the basis 
of the data generated during the Phase 2 program. It was associated with a high inhibition of 
ovarian function, no ovulation, a good safety profile, and the most favorable bleeding 
pattern/cycle control observed among the different E4 combinations that were evaluated (see 
Section 7.2). 
The investigational product is administered once daily following a 24/4-day regimen, i.e. one 
15 mg E4/3 mg DRSP active tablet per day for 24 consecutive days followed by one placebo 
tablet per day for 4 consecutive days.  
This 28-day cyclic regimen must be taken for 13 consecutive cycles. The treatment must be 
taken once daily at approximately the same time of the day. 
9.4.4.1 
Instructions for starting the first pack of tablets 
 Women who did not use any contraceptive method or who used a barrier 
contraceptive method will be instructed to begin the investigational product on the 
first day of the next menstrual bleeding. Starting on Days 2-5 is also allowed, but a 
condom must be used until the subject has completed 7 days of uninterrupted active 
tablet intake. 
 Women switching from another COC or progestin-only pill will start the 
investigational product at the time when the next pill pack of the previous pill would 
have been due. 
 Women switching from a hormonal vaginal ring or transdermal patch will start the 
investigational product when the next application would have been due. 
 Women switching from an injectable hormonal method of contraception will start 
the investigational product on the first day of the menstrual bleeding, which can 
vary depending of the form: 10 months after the injection of a product with a 3-

month duration, 6 months after the injection of a product with a 2-month duration 
and 3 months after the injection of a product with a 1-month duration. Starting on 
Days 2-5 is also allowed, but a condom must be used until the subject has completed 
7 days of uninterrupted active tablet intake. 
 Women switching from an intrauterine or dermally implantable contraceptive will 
start the investigational product on the day of removal. A condom must be used 
until the subject has completed 7 days of uninterrupted active tablet intake. 
The first day of the first pink tablet intake after enrollment is Day 1.  The subject places one 
of the 7 self-adhesive day label strips that corresponds to her Day 1 starting day onto the card 
of the blister to indicate the day she started. The study staff will show the subject how to fix 
the first label.  
She then starts taking one tablet daily, at approximately the same time of the day, beginning 
with the first pink tablet in the top row.  The subject completes her 28-tablet regimen when she 
has taken the last tablet in the blister pack.   
9.4.4.2 
Dosing Instructions 
Each time investigational product is dispensed to the subject, site personnel will instruct the 
subject as follows:  
 Take one pink tablet every day for 24 consecutive days (Day 1 through Day 24), 
followed by one white placebo tablet every day for 4 consecutive days (Day 25 
through Day 28). 
 When the pack of tablets is empty, start the next pack on the next day after the last 
white tablet of the previous pack has been taken. When starting a new pack of 
tablets, take the first pink tablet of the pack. There should be no interruption 
between two blister packs. 
 Take the investigational product at approximately the same time each day 
throughout the study.  The time of day should be determined by the subject.  
 
9.4.4.3 
Instructions in case of missed tablet(s) or in conditions potentially 
reducing the contraceptive efficacy 
If the subject inadvertently misses one or more of the tablets or, 
 In case of vomiting within 4 hours after the tablet intake or, 
 In case of diarrhea within 4 hours after the tablet intake, 
the following instructions 6 must be followed:   


 
 
  
Study MIT-Es0001-C301 
Amendment Final Version 2.1 
 
 
 
Confidential 
Page 32 of 155 
 If one active pink tablet is late (< 24 hours since a tablet should have been 
taken) or if one active pink tablet has been missed (24 to < 48 hours since a 
tablet should have been taken):  
o Take the late or missed active pink tablet as soon as possible. 
o Continue taking the remaining active pink tablets at the usual time 
(even if it means taking two active pink tablets on the same day). 
o Use of condom is not required. 
 If two or more consecutive active pink tablets have been missed (≥ 48 hours 
since a tablet should have been taken): 
o If between Day 1 & Day 17: 
 Take the most recent missed active pink tablet as soon as 
possible (any other missed tablets should be discarded). 
 Continue taking the remaining active pink tablets at the usual 
time (even if it means taking two tablets on the same day). 
 Use condom or avoid sexual intercourse until 7 days of 
uninterrupted active pink tablet intake. 
o If between Day 18 & Day 24:  
 Omit the hormone-free interval by finishing the active pink 
tablets in the current pack and starting a new pack the next 
day. 
 If unable to start a new pack immediately, use condoms or 
avoid sexual intercourse until 7 days of uninterrupted active 
pink tablet intake from the new pack. 
 If this occurs during the last cycle, the subject should contact 
the study staff to know what she has to do with the next 
contraception. 
 
 If the subject inadvertently misses any of the white placebo tablets: 
o Skip the missed white placebo tablet(s) and the remaining tablets are taken 
at the regular time.  
o Use of condoms is not required during this time.   
 A new pack of tablets should be started immediately after the day the last white 
tablet was taken. There should be no interruption between two blister packs.  
Anytime a subsequent cycle of the product/pack is started later than the day 
following administration of the last white tablet, the subject should use condoms 
until she has taken pink tablets daily for 7 consecutive days.

 Return all blister packs to site personnel at the following visit. 
 
9.4.4.4 
In case of short-term intake of drugs that may decrease the efficacy of 
the COC  
Subject is allowed to take drugs potentially decreasing the efficacy of the COC for a maximal 
period of 10 consecutive days (for example, CYP 3A4 inducers). Subjects must be instructed 
to use condoms when these drugs are used and during 7 days of uninterrupted pink tablet intake 
after finishing the medication. 
 
9.4.4.5 
Use of the investigational product in case of bleeding/spotting episode 
Scheduled bleeding is expected to begin within a few days of taking the last active tablet (i.e. 
pink tablet), but may begin sooner or later. If spotting occurs while on the usual regimen of 
one tablet daily, the subject should continue medication without interruption.  She should be 
instructed that this type of bleeding is often transient and without significance.  However, if 
the bleeding is persistent or prolonged, nonfunctional causes may be considered and the subject 
should be advised to call the Investigator who will decide the best management for the subject. 
The bleeding profile will be recorded by the subject on a subject diary.  
9.4.4.6 
Use of the investigational product in the event of a missed menstrual 
period 
A missed menstrual period may occur even if the subject adhered to the prescribed dosage 
regimen. However, as the contraceptive method used in this study is still under investigation, 
a rapid detection of any pregnancy is necessary. For this reason, if the subject presents a missed 
period, she will be instructed to use the home urine pregnancy test provided by the study staff 
to rule out pregnancy before continuing the contraceptive regimen (see Section 9.6.2).

Page 34 of 155 
Unauthorized Prior Therapies: 
 Use of an injectable hormonal method of contraception within 10 months (300 
days) prior to screening for an injection with a 3-month duration, within 6 months 
(180 days) prior to screening for an injection with a 2-month duration, within 3 
months (90 days) prior to screening for an injection with a 1-month duration. 
 Use of drugs potentially triggering interactions with COC within one month prior 
to subjects’ enrollment. This includes, but is not limited to: 
o CYP 3A4 inducers: barbiturates, primidone, bosentan, felbamate, griseofulvin, 
oxcarbazepine, topiramate, carbamazepine, phenytoin, rifampicin, St John’s 
wort. 
o CYP 3A4 inhibitors: azole antifungals, phenylbutazone, modafinil, cimetidine, 
verapamil, macrolides, diltiazem and grapefruit juice. 
o HIV/HCV protease inhibitors and non-nucleoside reverse transcriptase 
inhibitors. 
Unauthorized Concomitant Therapies: 
 Use of any contraceptive method other than the investigational product.  
Note: use of condoms is only allowed during the course of the study to avoid 
transmission of sexually transmitted infections (STIs), or in case of missed tablets,  
or whenunauthorized concomitant therapy(ies) are used. Condom use must be 
recorded in the subject diary. Daily, long-term treatment for chronic conditions or 
diseases with medications that may increase serum potassium concentration (e.g. 
ACE inhibitors, angiotensin-II receptor antagonists, potassium-sparing diuretics, 
potassium supplementation, heparin, aldosterone antagonist and non-steroidal anti-
inflammatory drugs). 
 Use of drugs potentially triggering interactions with COC. This includes, but is not 
limited to: 
o CYP 3A4 inducers: barbiturates, primidone, bosentan, felbamate, griseofulvin, 
oxcarbazepine, topiramate, carbamazepine, phenytoin, rifampicin, St John’s 
wort.  
o CYP 3A4 inhibitors: azole antifungals, phenylbutazone, modafinil,   cimetidine, 
verapamil, macrolides, diltiazem and grapefruit juice. 
o HIV/HCV protease inhibitors and non-nucleoside reverse transcriptase 
inhibitors. 
These drugs or herbal products may decrease the effectiveness of hormonal 
contraceptives or increase breakthrough bleeding. Subjects must be instructed 
to use a back-up contraceptive method when these drugs are used, up to and 
including the next 7 days after finishing the concomitant therapy and to record 
this back-up contraception in the subject diary (see Section 9.6.1). It is the 
responsibility of the Investigator to ensure that any change in concomitant

medications during the study is recorded in the source documentation and 
entered in the electronic case report form (eCRF). 
Warning: oral contraceptives may interfere with the metabolism of other drugs. Accordingly, 
plasma and tissue concentrations may be affected (e.g. cyclosporine). Consult the prescribing 
information of concomitant drugs for possible interactions with oral contraceptives. 
9.4.6.2 
Condoms and other contraceptive methods 
Use of condoms is allowed during the course of the study only to avoid transmission of STIs 
or in case of missed tablet(s) or unauthorized concomitant therapy(ies). Condom use must be 
recorded in the subject diary. Use of any other contraceptive methods must also be recorded in 
the subject diary (see Section 9.6.1). The cycles during which condom(s) or other contraceptive 
method(s) than the investigational product were used will be excluded from the Pearl Index 
calculation. 
9.4.7 
Treatment beyond the clinical trial 
Post-treatment contraceptive counseling should be given to each subject at Visit 6 and at the 
Early Termination Visit in case of premature study termination. Post-treatment contraceptive 
treatment should be started no later than on the day following the last tablet intake of the trial 
medication.

9.5.4 
Early Termination Visit 
A subject who desires early termination or is withdrawn from the study after the enrollment 
visit (Visit 2) (section 13.4) will require an Early Termination Visit. 
 Any subject should be instructed at each visit to contact the study staff before 
discontinuing the study drug to be counseled about alternative contraception to use 
prior to the Early Termination Visit (see Section 9.6.4.8). Study sites may provide any 
prescription or non-prescription contraceptive to the subject as is medically appropriate 
per local standard of care other than an IUD or implant. If necessary, an unscheduled 
visit can occur to provide contraception (see Section 9.5.5). 
 A subject who presents to the study site for a scheduled visit and desires to discontinue 
study participation or is withdrawn from the study at that visit should be counseled 
about alternative contraception to use prior to the Early Termination Visit (see Section 
9.6.4.8). Study sites may provide any prescription or non-prescription contraceptive to

Page 43 of 155 
the subject as is medically appropriate per local standard of care other than an IUD or 
implant. 
 A subject who presents to the study site for a scheduled visit who has not taken the 
study product for 11 days or more should have the scheduled visit procedures and the 
Early Termination Visit procedures completed at that time. The subject should be 
counseled about alternative contraception (see Section 9.6.4.8). Study sites may 
provide any prescription or non-prescription contraceptive to the subject as is medically 
appropriate per local standard of care. 
The Early Termination Visit should occur between 11 and 18 days after the last investigational 
product intake or immediately if the investigational product was never started. 
The procedures listed in Visit 7 (see Section 9.5.3.6) will be performed and the End of Study 
Form will be completed.  
Study site personnel will attempt to follow the progress of every subject admitted to the study 
through to study completion. If a subject fails to return for a scheduled visit, a reasonable effort 
should be made to contact the subject and ascertain the reason(s) for not returning. As a 
minimum, the site staff will contact the subject twice by phone and, if no response, will send 
a letter by registered mail. 
If a subject does not complete the study for any reason (including Investigator discretion), the 
reason and circumstances for the subject’s early termination must be fully documented.   
The Sponsor or Designee must be informed in a timely manner if any subject withdraws from 
the study, regardless of the cause. Withdrawn subjects may not be re-enrolled in the study and 
will not be replaced. 
9.5.5 
Unscheduled Visit 
At any time of the study, an Unscheduled Visit could occur in case of suspicion of pregnancy 
based on a positive pregnancy test performed at home by the subject or in case the Investigator 
judges it necessary to examine a subject who would present a potential significant adverse 
event in the Investigator’s opinion, or if alternative contraception is needed for a subject 
planning early termination. Additional assessments can be performed at the Investigator’s 
discretion. 
9.6 
Study Variables and Procedure Descriptions 
9.6.1 
Subject Diary 
Subject diaries will be given to the participating subjects at Visit 2. Subjects will be instructed 
on how to complete it by the Investigator or Designee.  
The following information is to be recorded in the subject diary: 
- 
Date of the intake of the first tablet at each cycle; 


 
 
  
Study MIT-Es0001-C301 
Amendment Final Version 2.1 
 
 
 
Confidential 
Page 44 of 155 
- 
Tablet intake on a daily basis; 
- 
Absence or occurrence of vaginal bleeding/spotting event(s) on a daily basis: 
 0 = Absence of vaginal bleeding or spotting; 
 1 = Spotting: evidence of minimal vaginal blood loss that does not 
require new use of sanitary protection, including pantyliners; 
 2 = Bleeding: evidence of vaginal blood loss that requires the use of 
sanitary protection with a tampon, pad or pantyliner; 
- 
Use of contraceptive method other than the investigational product (e.g. condom) 
during the cycle;  
- 
Occurrence of heterosexual intercourse during the cycle; 
- 
Result of the urine pregnancy test(s) performed at home (at cycle 1 before the first pill 
intake and at subsequent cycles in case of absence of menstruation). 
At Visits 3, 4, 5, 6 and 7, the completed pages of the subject diary will be collected and 
reviewed by the Investigator. At Visits 3, 4, 5, and 6 the subject diary will be returned to the 
subject for further completion. At Visit 7, the fully completed last pages of the subject diary 
will be returned by the subject. 
9.6.2 
Efficacy Assessments 
Contraceptive efficacy will be based on the Pearl Index, the method failure Pearl Index and the 
cumulative pregnancy rate.  
On-treatment pregnancies are defined as pregnancies with an estimated date of conception 
within the in-treatment period (Day 1 to 2 days after the intake of investigational product, 
whether active or inactive tablet). 
Pre-treatment pregnancies are pregnancies with an estimated date of conception before the first 
intake of trial medication. 
Post-treatment pregnancies are pregnancies with an estimated date of conception after the in-
treatment period (> 2 days after the intake of investigational product, whether active or inactive 
tablet). 
9.6.2.1 
Pregnancy Testing and Estimating Date of Conception 
The occurrence of pregnancies will be evaluated during the study by performing: 
 
- 
At Screening Visit (Visit 1) and Visit 7: a serum pregnancy test; 


 
 
  
Study MIT-Es0001-C301 
Amendment Final Version 2.1 
 
 
 
Confidential 
Page 45 of 155 
- 
Just before intake of the first study medication and in case of missing menstrual period, 
the subject will perform a urine pregnancy test at home. For that purpose, home 
pregnancy kits will be provided to all subjects at Visit 2 and the subjects will be 
instructed on how to use it. In case of positive urine pregnancy test result, the subject 
will be instructed to contact the study staff immediately and the subject will be 
instructed not to take the investigational product. An appointment will be scheduled 
with the study staff for the pregnancy follow-up as soon as possible. The subject will 
be asked to record in the subject diary (see Section 9.6.1) the result of the urine 
pregnancy test performed at home; 
- 
For the subjects included in the endometrial safety Substudy, an additional urine 
pregnancy test will be performed at the study site before performing the endometrial 
biopsy (Visit 7a). 
At any time: the subject is asked to contact the study staff in the event of a suspected pregnancy. 
An appointment will be scheduled with the study staff for the pregnancy confirmation as soon 
as possible. The Investigator and or Designee will make every effort to see the subject as soon 
as possible to perform a serum pregnancy test.   
All subjects for whom a pregnancy is suspected due to a positive serum pregnancy test will be 
carefully evaluated and assessed to determine the estimated date of conception.  The preferred 
method is to perform an ultrasound to define the estimated age of the pregnancy; the estimated 
date of conception will then be calculated from this result.  In addition, information about all 
pregnancy tests, about bleeding and study drug intake (which must be reconciled with subject 
diary data), information about concomitant medications (which must be reconciled with 
information in the eCRF) will be obtained.  The Sponsor and Site Monitor must be notified 
and available information captured.  All information must be documented using the Pregnancy 
Report Form.  
Information pertaining to the reporting of pregnancy should be captured on the Pregnancy 
Report Form. This form will be used for initial and follow-up reporting. The form should be 
completed and returned to the PRA Safety team. The subject will be followed until the outcome 
of pregnancy is known.   
9.6.2.2 
Pregnancy Reporting 
Pregnancy will not be considered an AE but, because of its importance, information about each 
pregnancy should be treated in an urgent manner.  The Sponsor or Designee must be notified 
within 24 hours of the suspected diagnosis and all follow-up information should be obtained 
promptly. 
If during the course of the study, a subject is found to be pregnant, the investigational product 
will be discontinued and study participation terminated.  
The site will submit a Pregnancy Report Form to the Safety Monitor.

All pregnancies identified during the course of the study in a subject who was using the 
investigational product will be monitored to completion, i.e., approximately 9 month follow-
up in the case of live birth or until outcome information is obtained. Information will also be 
collected on any maternal or fetal complications. Miscarriage and any congenital abnormalities 
or birth defects will be classified as SAEs. Pregnancy outcome information will be recorded 
on specific forms and the data will be analyzed within the drug safety assessment.  Every 
attempt should be made to obtain outcome data including hospital or medical records. If a 
subject becomes pregnant and states she never started the investigational product, the 
pregnancy does not have to be monitored if the subject returns all of the investigational product 
(proving she never started the investigational product). 
 
9.6.3 
Safety Variables 
Safety evaluations will include the following: 
 General safety will be assessed in terms of occurrence of AEs/SAEs;  
 Extent of exposure 
 Clinical laboratory evaluations 
 Physical examination 
 Gynecological examination  
 Vital signs 
 Endometrial histology (assessed in subjects participating in the endometrial safety 
Substudy who are treated for at least 10 complete cycles). 
9.6.3.1 
Adverse Events 
AEs will be assessed from the time of signing the IC until exit from the study.  At every study 
visit from Visit 2, subjects will be asked an indirect standard question to elicit any medically 
related changes in their well-being.  They will also be asked if they have been hospitalized,

had any accidents, used any new medications, or changed any current medication regimens 
(both prescription and over-the-counter medications). 
Definition of Terms 
Adverse Event (AE):  Any untoward medical occurrence associated with the use of a drug in 
humans, whether or not considered drug related. In addition to novel events, an AE may be an 
exacerbation of a pre-existing medical condition that was present before the subject was 
assigned to a treatment group.  Each AE is described using all three of the following 
classifications: expected or unexpected; related or unrelated; and serious or non-serious.  
Additionally, intensity of the event is also described. 
Treatment-emergent adverse event (TEAE): A TEAE is any AE not present prior to the 
initiation of the treatments or any event already present that worsens in either intensity or 
frequency following exposure to the treatment. Since the starting point for AEs collection is 
the signing of the IC, not the start of the study treatment, the AEs recorded prior to first 
investigational product administration are designated as AEs while those that occur or worsen 
after the initiation of the investigational product are designated as TEAEs.   
Exacerbation of Pre-Existing Medical Condition:  An increase in the frequency or severity 
of a medical condition that is present before first investigational product administration.  Any 
medical condition that is present before first investigational product administration and that 
does not deteriorate should not be reported as an AE. 
Expected: The determination of whether an AE is expected is based on previous experience 
with the investigational product, as follows: 
Expected AEs are AEs that have already been identified during the investigational product’s 
use, or are a known complication of standard medical procedures that may be conducted as 
part of the clinical study. 
Expected AEs are defined as those described in the Investigator’s Brochure (IB).  If an event 
increases in intensity or severity from that described in the IB, it will be considered unexpected. 
Unexpected AEs are all other AEs which are not deemed anticipated.  Note that anticipated 
AEs which are more severe must also be considered unanticipated AEs. 
Severity: The severity of each AE should be recorded as mild, moderate, or severe according 
to the following definition: 
Mild – transient and well-tolerated by the study subject, 
Moderate – causes discomfort and a temporary interference with daily living, 
Severe – substantially interferes with daily living to the point of being incapacitating and/or 
life threatening.

Serious:  An AE is considered “serious” if, in the view of either the Investigator or Sponsor, 
it results in any of the following outcomes:  
• Death: the AE causes or contributes to the death.  Death is usually considered to be the 
outcome of an event; the event that leads to death is defined as the SAE. 
• A life-threatening adverse event: if, in the view of the Investigator or Sponsor, its 
occurrence places the subject at immediate risk of death. It does not include an AE that, 
had it occurred in a more severe form, might have caused death. 
• Inpatient hospitalization or prolongation of existing hospitalization: the AE requires at least 
a 24-hour inpatient hospitalization or prolongs a hospitalization beyond the expected length 
of stay. Hospital admissions for surgery planned before study entry, for social reasons or 
for normal disease management procedures are not to be considered SAE according to this 
criterion.  Where the protocol or the standard management of the disease under study 
requires planned hospitalizations for disease or treatment management, this should not be 
considered a serious criterion leading to expedited reporting. 


 
 
  
Study MIT-Es0001-C301 
Amendment Final Version 2.1

Page 50 of 155 
• Persistent or significant incapacity or substantial disruption of the ability to conduct normal 
life functions. 
• Congenital anomaly/birth defect: an adverse outcome in a child or fetus of a patient 
exposed to the investigational product before conception or during pregnancy. 
• Important medical event: such an event may not result in death, be life-threatening, or 
require hospitalization but may be considered serious when, based upon appropriate 
medical judgment; it may jeopardize the 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. 
 
For the purpose of this study, all events that meet the regulatory definition of an SAE that occur 
at any time during the study will be reported to the Sponsor as SAEs. Any SAE requires 
expedited reporting to Sponsor regardless of its relationship to the investigational product. 
Non-SAEs are all other AEs not deemed serious. 
Investigator Obligations 
Assessing and Following:  The Investigator is responsible for assessing all AEs that occur at 
any time during the study.  The Investigator must make a determination of relatedness, 
seriousness, and intensity on the Adverse Events page of the eCRF for each AE.  All AEs must 
be followed to adequate resolution or stabilization.  If the AE has not resolved or stabilized by 
the time the subject completes the final study visit, the Investigator will follow the status of 
the subject's AE for at least 30 days beyond the subject's final study visit, unless directed 
otherwise by the Sponsor. 
Documenting:  All AEs during the study will be documented in the subject’s medical record.  
This information will then be transcribed on the AEs page of the eCRF by designated study 
personnel.  Required information includes a description of the event, date of onset, date of 
resolution, if death occurred, the action taken to manage the AE, as well as relatedness, 
seriousness, and intensity. 
AE information must be recorded regardless of its relatedness to the use of the investigational 
product.  AEs resulting from concurrent illnesses, reactions to concurrent medications, or 
progression of disease states must also be reported. 
Reporting:  1) The Investigator is responsible for reporting AEs to the Ethics Committee (EC) 
according to agreements and instructions from that committee that oversees this research, as 
well as according to applicable regulations. 2) Additionally, all AEs will be reported to the 
Sponsor or Designee on the eCRF, and all SAEs, whether expected or unexpected, related or 
unrelated, must be reported to PRA Drug Safety , by 24/7 e-mail or facsimile using the “Serious 
Adverse Event Report” form provided by the Sponsor or Designee, within 24 hours after the

Investigator first learns of the event   In addition to the form, the following completed eCRF 
pages containing relevant information must also be faxed/mailed to the PRA Drug Safety: 
Medical History and Current Medications. The Investigator is responsible for reporting any 
new or relevant follow-up information on the SAEs within 24 hours after the investigator learns 
of the new information.  The Investigator should cooperate and furnish additional information, 
including copies of pertinent records if necessary, to assist the safety team in their evaluation 
of the event. 
Medical Emergencies and Emergency Protocol Deviations 
In medical emergencies, the Investigator will use medical judgment and remove the subject 
from immediate harm.  The Investigator will then immediately notify the Safety Monitor and 
the EC regarding the type of emergency and the course of action taken. 
An investigator shall notify the Safety Monitor and the reviewing EC of any deviation from 
the investigational plan to protect the life or physical well-being of a subject in an emergency.  
Such notice shall be given as soon as possible, but in no event later than 5 working days after 
the emergency occurred.  Except in such an emergency, prior approval by the Safety Monitor 
is required for any changes in or deviations from the protocol.  All deviations must be 
documented on the eCRF.

Any remaining retainable biological samples will be stored at the central laboratory or designee 
at the latest until the marketing authorization. These samples may be used for future additional 
analysis in the context of the E4/DRSP development program.  
At Visit 1 and 7, blood hematology, biochemistry and lipids will be assessed (see Appendix 
2). At Visit 5, the following biochemistry parameters will be assessed: glycaemia, glycated 
hemoglobin, total cholesterol, HDL- and LDL-cholesterol, triglycerides, Lactate 
dehydrogenase (LDH) 1 and LDH 2, renal function (urea, creatinine, and glomerular filtration 
rate [GFR]) and ionogram (Na, K, Cl, Ca2+, P, HCO3-). Subject should be fasting for 8 hours 
before blood collection. 
All out-of-range laboratory values that are considered by the Investigator to be clinically 
significant will be recorded as AEs (see Section 9.6.3.1) 
9.6.3.4 
Physical Examination 
A physical examination will be performed at Screening Visit and Visit 7. The physical 
examination will include an evaluation of the following: body as a whole, skin, head, eyes, 
ears, nose, and throat (HEENT), neck, cardiovascular, respiratory, musculoskeletal, 
neurologic, lymphatic/thyroid, abdomen. 
When reporting the results of the physical examination, the use of the “Abnormal” category 
will be reserved for findings that are considered clinically significant, in the opinion of the 
Investigator; the “Normal” category will include “Abnormal” results that are not clinically 
significant, as well as no findings.   
All abnormal findings will be recorded as AEs (see Section 9.6.3.1). 
9.6.3.5 
Height, Weight and Body Mass Index 
Height will be recorded at Screening Visit only. Weight will be recorded at Screening Visit, 
Visit 4, Visit 5 and Visit 7. At each center the same balance will be used for all measurements. 
Subjects will wear only indoor clothing without shoes. BMI will be calculated at the Screening 
Visit, Visit 4, Visit 5 and Visit 7 using the following formula:  
𝑊𝑒𝑖𝑔ℎ𝑡
𝐻𝑒𝑖𝑔ℎ𝑡² (kg/m²). 
9.6.3.6 
Gynecological Examination, Chlamydia test, Gonorrhea test and Cervical 
Cytology 
A gynecological examination will be performed at Screening Visit and Visit 7. The 
gynecological examination will include an evaluation of the following: breast examination 
(performed by palpation) and assessment of the adnexa, cervix, uterus, vagina, and external 
genitalia.

clinically significant, as well as no findings. 
All abnormal findings will be recorded as AEs (see Section 9.6.3.1). 
A Chlamydia testing will be performed using a vaginal swab: 
 At Screening (Visit 1) for all subjects. 
 At Visits 2, 3, 4, 5 and 6 for subjects who reported a change in sexual partner since the 
last study visit. 
In case of positive Chlamydia test result, the subject will be treated, at the Investigator’s 
discretion as this infection can influence the vaginal bleeding pattern. In case of positive 
Chlamydia test result at screening, the subject will start treatment before she is enrolled.  
A gonorrhea testing will be performed using a vaginal swab: 
 At Screening (Visit 1) for all subjects.  
 At Visits 2, 3, 4, 5, and 6 for subjects who reported a change in sexual partner since the 
last study visit.  
In case of positive gonorrhea test result, the subject will be treated, at the Investigator’s 
discretion as this infection can influence the vaginal bleeding pattern. In case of positive 
gonorrhea test result at screening, the subject will start treatment before she is enrolled.  
 
For cervical cytology, Pap testing will be performed at Screening in all women 20 years 0 
months of age or older if no documented Pap test has been performed in the last 18 months.  
The enrollment visit cannot be performed until this Pap test result is available and the subject 
meets entry criteria. A copy of any Pap test or follow-up testing used for determination of study 
eligibility or during study follow-up must be obtained and included in the study record.  If not 
available at the time of the visit for which the documentation is required then the Pap test 
should be performed per protocol. The results of the Pap test will be reported using the 
Bethesda Pap Smear Classification7 as detailed in Appendix 3. If the Pap test at the Screening 
Visit presents abnormal result (i.e. dysplasia, cervical intraepithelial neoplasia, squamous 
intraepithelial lesion, carcinoma in situ, invasive carcinoma), the subject cannot be enrolled in 
the study.  Enrollment of a subject with an ASCUS interpretation is permitted if the subject is 
less than 21 years of age or HPV reflex test is negative for high-risk oncogene virus. If the 
ASCUS interpretation was done on the Pap test performed in the past 18 months, enrollment 
of the subject is allowed if a repeat Pap test 6 months later was normal.   
All abnormal findings in cervical cytology after subject enrolment that are considered by the 
Investigator to be clinically significant will be recorded as AEs (see Section 9.6.3.1).

Vital Signs 
Vital signs will be measured at Screening Visit, Visits 2, 3, 4, 5, 6, and 7. 
Vital signs will include sitting systolic and diastolic blood pressures and heart rate. Blood 
pressure measurements will be made using a sphygmomanometer with an appropriate cuff size 
for the individual subject.  Measurements will be taken while the subject is seated after at least 
5 minutes at rest. 
All abnormal findings in vital signs that are considered by the Investigator to be clinically 
significant will be recorded as AEs (see Section 9.6.3.1). 
9.6.3.8 
Endometrial Biopsies 
Endometrial biopsies will be used for the evaluation of endometrial safety. Endometrial 
biopsies will be obtained from subjects included in the endometrial safety Substudy at the 
Screening Visit and at Visit 7a if the subject has completed at least 10 cycles. Endometrial 
biopsies will be performed between Days 12 and 19 of the cycle. Pregnancy tests must be done 
to confirm that subjects are not pregnant prior to any biopsy. 
Subjects can be given sedation and/or pain relief prior to the procedure under standard local 
care provided that the medications are not listed as unauthorized therapies in Section 9.4.6.1 
and as per Investigator judgment. If insufficient tissue specimen is obtained, the endometrial 
biopsy will be repeated within 4 weeks. 
Endometrial tissue will be obtained using a pipelle. Women will receive counselling to include 
discharge instructions and to expect mild to moderate bleeding that can last for a few days and 
will be advised to call the site if they experience fever, pain or increased or prolonged bleeding. 
The endometrial tissue obtained by endometrial biopsy will be processed by a central 
laboratory.  Two independent pathologists will assess the slides from the endometrial biopsies.  
In case of discrepancy between both pathologists’ assessments, a third independent pathologist 
will assess the slide. If concurrence is not reached, the worst diagnosis will be used. Detailed 
procedures for obtaining endometrial biopsies, tissue preparation and endometrial biopsy 
assessment will be described in separate study manuals to be provided to the sites. 
Samples will be stored at the central laboratory to allow re-reading, as deemed necessary.  
Digital recording of diagnostic areas of the slides will also be maintained.  
Standardized criteria as provided in Blaustein’s pathology test (Pathology of the Female 
Genital Tract 8) will be used for diagnosis of endometrial hyperplasia and are provided in 
Appendix 4. If endometrial hyperplasia or carcinoma is determined, the subject will 
immediately discontinue study product and will receive standard clinical management. A 
Serious Adverse Event report is to be completed and the Sponsor will be notified according to 
SAE procedures.

occurrence of intercourse and the use of back-up contraception (e.g. use of condoms) if any.  
9.6.4.8 
Contraceptive Counseling 
At Visit 6, the subject will be counseled about her future contraception. The choice of the 
contraceptive method is left to the Investigator’s discretion.  
A subject who desires early termination or is withdrawn from the study (see Section 13.4) after 
the enrollment visit (Visit 2) will be counseled about future contraception. 
 Any subject should be instructed at each visit to contact the study staff before 
discontinuing the study drug to be counseled about alternative contraception to use 
prior to the Early Termination Visit. Study sites may provide any prescription or non-
prescription contraceptive to the subject as is medically appropriate per local standard 
of care other than an IUD or implant. If necessary, an unscheduled visit can occur to 
provide contraception (see section 9.5.5). 
 A subject who presents to the study site for a scheduled visit and desires to discontinue 
study participation or is withdrawn from the study at that visit should be counseled 
about alternative contraception to use prior to the Early Termination Visit. Study sites

On the day the subject is expected to start this contraception (± 1 day), the 
Investigator/Designee will contact the subject by phone to ensure her compliance with the 
counseled contraceptive method.  
9.6.4.9 
Acceptability of Trial Medication 
The acceptability of the trial medication will be assessed by analysis of discontinuation rates 
and reasons for discontinuations. Subject’s premature discontinuation must be documented on 
the Treatment Discontinuation Form, including the most important reason for discontinuation. 
The most important reason for discontinuation will be categorized as AE, lost to follow-up, 
subject request, protocol deviation, pregnancy, pregnancy wish or other. Subjects that complete 
the study must be documented on the End of Study Form. 
9.6.4.10 
Subjects’ well-being 
Subjects’ well-being will be evaluated using two well-established questionnaires: the Quality 
of Life Enjoyment and Satisfaction Questionnaire – Short Form and the Menstrual Distress 
Questionnaire.  
The baseline questionnaires will be given to the subject at Visit 2. The subject will be instructed 
to fill them in at home on or before the first day of study medication intake (Day 1). At the 
next visit, the study site personnel will ensure for the questionnaire completion. 
The end-of-treatment questionnaires will be given to the subject at Visit 6. The subject will be 
instructed to fill them in at home between Day 7 and Day 14 of the 13th treatment cycle. At the 
next visit, the study site personnel will ensure for the questionnaire completion. 
In case of premature study discontinuation, the subjects will be asked to fill in the 
questionnaires during the Early Termination Visit.

12 PLANNED STATISTICAL METHODS 
Detailed plans for the statistical methods will be provided in a Statistical Analysis Plan which 
will be finalized prior to database lock. 
12.1 Determination of Sample Size 
Sample size is based on needing a sufficient number of cycles such that the difference between 
the Pearl Index and the upper limit of the two-sided 95% confidence interval (CI) for the Pearl 
Index does not exceed 1.  Assuming that the true Pearl Index is 1.0 and that a Poisson model 
is used to derive the CIs, then at least 12,337 at risk cycles are required for a power of 90% in 
the 18 to 35 year old population 9..  If a not at risk cycle rate of 10% and a dropout rate of 
approximately 30% (assuming that we have an average of 4 cycles for subjects that 
discontinue) are assumed, approximately 1350 18-to-35 year old subjects need to be 
enrolled.  Additionally, it is planned to enroll a maximum of 200 subjects > 35 years. 
Therefore, in total, approximately 1550 subjects will be enrolled in the study. 
No formal sample size has been estimated for the endometrial safety Substudy.  Approximately 
100 subjects with both a Screening and Visit 7a biopsies are planned to be included in the 
endometrial safety Substudy.  Assuming a 40% dropout rate for a 13-cycle treatment will yield 
approximately 167 subjects who will have a screening biopsy performed at selected sites. 
12.2 Analysis Populations and Datasets 
Statistical analysis and data tabulation will be performed using the following analysis 
populations unless specified otherwise: 
 Screened population includes all subjects who signed an IC form. 
 Enrolled population includes all enrolled subjects. 
 Safety population includes all enrolled subjects who receive at least one dose of test 
article. 
 Intention-to-Treat (ITT) population includes all enrolled subjects who receive at least 
one dose of test article.  The ITT population is the same as the Safety population for 
this study. 
 Per-protocol (PP) population includes all subjects in the ITT population who complete 
the study and do not have any important protocol deviations that impact the statistical 
analysis. The PP population may differ for the different endpoints.

12.3 General Statistical Procedures  
All the analyses will be conducted with SAS using procedures appropriate for the particular 
analysis. 
The descriptive statistics for all the continuous variables presented will be mean, median, 25th 
percentile, 75th percentile, standard deviation (SD), standard error of mean (SEM), minimum, 
maximum, and number of subjects.   
Categorical variables will be summarized using counts and percentages. 
Baseline will be defined as the most recent assessment prior to first dose of study medication. 
12.4 Efficacy Analyses 
The efficacy analysis will be based on the Pearl Index. The Pearl Index, defined as the 
number of pregnancies per 100 women-years of treatment, will be calculated as 
𝑃𝑒𝑎𝑟𝑙 𝐼𝑛𝑑𝑒𝑥=
1300 ×  number of on −treatment pregnancies
number of women −28 day equivalent cycles of treatment 
Only at risk cycles, i.e. cycles in which no other methods of birth control (including condoms) 
are used and during which the subjects confirmed that sexual intercourse has occurred, will be 
included in the denominator of the Pearl Index calculation.  The subject diary data will be used 
to determine whether additional birth control methods were used and whether the subject has 
had intercourse. 
Note that if conception occurs in a cycle, then that cycle will be included in the denominator 
even if other methods of birth control were used during that cycle or the subject did not confirm 
that they had had sexual intercourse. Cycles after the cycle of conception will be excluded from 
the denominator. All on-treatment pregnancies will be included in the numerator for the Pearl 
Index.   
On-treatment pregnancy is defined as pregnancy with an estimated date of conception within 
the on-treatment period, i.e. Day 1 to 2 days after the intake of investigational product (whether 
active or inactive tablet). In cases where the date of conception cannot be established 
unequivocally (e.g. subjects is lost to follow-up), this pregnancy will be considered an on-
treatment pregnancy. For calculation purposes a cycle will be defined as 28 days. 
The method failure Pearl Index is calculated using the same method as the Pearl Index, but 
includes only those pregnancies that were classified as method failure and not pregnancies due 
to user failure, i.e. incorrect intake of the contraceptive product. Compliance data will be used 
to determine if the pregnancy was due to user failure. 
Each on-treatment pregnancy will be reviewed and classified as either a method failure or a 
user failure pregnancy prior to database lock. Pregnancies will only be designated as user

failures if there is documentation that the subject did not use the test article correctly during 
the treatment cycle the conception occurred, including the instructions to be followed in case 
of missed pill(s). 
12.4.1 
Efficacy Endpoints 
The efficacy endpoints are: 
 Pearl Index for subjects aged of 18 to 35 years, inclusive, at screening; 
 Pearl Index for all ages; 
 Method failure Pearl Index for subjects aged 18 to 35 years old, inclusive, at screening; 
 Method failure Pearl Index for all ages. 
 
The primary efficacy endpoint will be the Pearl Index in the ITT population aged 18 to 35 
years, inclusive, at Screening with at risk cycles (cycles in which no other methods of birth 
control (including condoms) are used and during which the subjects confirmed that sexual 
intercourse has occurred). Subjects in this age group will not be censored on their 36th birthday 
for the pregnancy assessment. 
 
12.4.2 
Statistical Analysis 
12.4.2.1 
Confidence Intervals for the Pearl Indices 
The 95% CI for the Pearl Indices will be presented for the 18 to 35 year age group and overall 
and for method failure for the ITT population including only at risk cycles in the denominator. 
For historical comparison the Pearl Index will also be calculated using the same method as 
described above including all at risk cycles and cycles where the subject did not have 
intercourse and did not use back-up contraception in the denominator. 
The 95% CI for Pearl Indices will be calculated based on using a Poisson distribution.   
12.4.2.2 
Life-Table Rates  
In addition, the cumulative pregnancy rate, as determined by life-table methods, together with 
the corresponding 95% CIs will be presented for all pregnancies and for all method failure 
pregnancies in the ITT population. This will be repeated for all ages and for subject’s age 18 to 
35 years inclusive at Screening. 
Life-table analyses will provide one-year life-table pregnancy rates for each efficacy endpoint 
(i.e. for all pregnancies as used in the Pearl Index and for all method failure pregnancies as used in 
the method failure Pearl Index).  The life-table analysis will evaluate the cumulative probability 
of pregnancy by cycle using PROC LIFETEST in SAS where the time variable is the cycle

where the estimated conception occurred for subjects who had an on-treatment event of 
pregnancy.  Subjects who did not have an on-treatment event of pregnancy will be censored 
on the cycle at which they discontinued from the study.  Cumulative probabilities of pregnancy 
and 95% CIs will be calculated based on Kaplan-Meier estimates for Cycle 13.  Additionally, 
the estimated survivor function against time (cycle) will be provided. 
12.4.3 
Statistical Subgroup Analyses  
If the sample size is adequate, subgroup analyses will be performed for the following 
categories: 
 BMI categories (< 30, ≥ 30); 
 Race category (White, Black, Asian, Other); 
 Starters/Switchers; 
 Smokers/Non-smokers; 
 Age (18-25; 25-35 and > 35 years old). 
12.5 Safety Analyses 
Safety variables will be summarized for the Safety population using descriptive statistics and 
frequency distributions as defined in the following sections.  
12.5.1 
Adverse Events 
TEAEs will be classified into a standardized terminology using the Medical Dictionary for 
Regulatory Activities (MedDRA) system organ classifications and preferred terms.  The latest 
available version of MedDRA will be used as coding dictionary.  Prior to database lock, the 
coding will be updated using the current version of MedDRA.  The incidence of TEAEs will 
be summarized for the Safety population.  Although a preferred term or system organ class 
may be reported more than once for a subject, each subject will only be counted once in the 
incidence count for that preferred term or system organ class.  Summaries of the following 
types will be provided: 
• Overall summary of TEAEs. 
• Summary of TEAEs by MedDRA system organ class, MedDRA preferred term, 
investigational product relationship, and intensity. 
• Summary of TEAEs by MedDRA preferred term and investigational product relationship 
in descending order of frequency. 
• Summary of treatment-emergent SAEs by MedDRA system organ class, MedDRA 
preferred term, and investigational product relationship.

Page 67 of 155 
• Summary of TEAEs by MedDRA system organ class, MedDRA preferred term, and 
investigational product relationship for the primary events leading to premature 
discontinuation from the study. 
 
These summaries will present the number and percentage of subjects reporting an AE for each 
classification level as well as the number of events reported.  The denominator for calculating 
the percentages for summaries will be based on the number of subjects in the overall Safety 
population. 
All AEs, SAEs and deaths, SAEs considered to be related to treatment, and AEs leading to 
premature discontinuation from the study will also be provided in data listings including non-
treatment emergent events. 
12.5.2 
Extent of Exposure 
The duration of exposure in days will be summarized using descriptive statistics for the 
Safety/ITT population.  Duration of exposure will be calculated as the difference between last 
tablet intake date and the first tablet intake date plus 1.  
Additionally, these summaries will present the number and percentage of subjects exposed for 
at least 26 weeks and at least 52 weeks.  The denominators for calculating the percentages will 
be based on the number of subjects in the Safety population. 
12.5.3 
Clinical Laboratory Evaluations 
For continuous clinical laboratory analytes, the absolute value and change from baseline will 
be summarized by analyte and visit using descriptive statistics for the Safety population.  
Categorical laboratory analytes, classified as normal or abnormal, will be summarized by 
analyte and visit using the number and percentage of subjects in each category for the Safety 
population.  The denominators for calculating the percentages will be based on the number of 
subjects with non-missing assessments at a particular visit for the Safety population. 
Shifts to values outside of the normal range will be presented by analyte and visit and will be 
summarized by the number and percentage of subjects with evaluable shifts. An evaluable shift 
is one where both the Screening Visit value and the on-treatment or early termination value 
are recorded for subjects in the Safety population. The denominators for calculating the 
percentages will be the number of subjects with an evaluable shift. 
All clinical laboratory values, abnormal clinical laboratory values, and clinical significant 
laboratory values will also be provided in data listings. 
12.5.4 
Physical examination 
Physical examination assessments will be summarized for the Safety population by visit.  For 
each body system and assessment category, the number and percentage of subjects will be

Vital Signs 
Vital sign measurements for the Safety population will be summarized using descriptive 
statistics by visit.  The change from baseline will also be summarized in the same manner. 
12.5.7 
Height, Weight and BMI 
Weight measurements and BMI calculation for the Safety population will be summarized using 
descriptive statistics by visit.  The change from baseline will also be summarized in the same 
manner. 
Height at baseline (Visit 1) will be summarized using descriptive statistics. 
12.6 Other Assessments or Analyses 
12.6.1

Table 1: Bleeding and spotting definitions 
Term 
Definition 
Bleeding  
Evidence of vaginal blood loss that requires the use of sanitary 
protection with a tampon, pad or pantyliner. 
Spotting 
Evidence of minimal vaginal blood loss that does not require new use of 
sanitary protection, including pantyliners. 
Episode of 
Bleeding/Spotting 
Bleeding/spotting days bounded on either end by 2 days of no bleeding 
or spotting. 
Scheduled 
Bleeding/Spotting 
Any bleeding/spotting that occurs during the hormone-free interval (i.e. 
Days 25 – 28) and continues through Days 1-3 of the subsequent active 
cycle, 
and 
Any bleeding/spotting that occurs while taking active hormones during 
Days 1-7 of the first cycle. 
Unscheduled 
Bleeding 
Any bleeding that occurs while taking active hormones that does not 
meet the criteria for scheduled bleeding. 
Unscheduled 
Spotting 
Any spotting that occurs while taking active hormones that does not 
meet the criteria for scheduled spotting. 
 
Bleeding patterns will be analyzed in the ITT and PP populations using data from the subject 
diary. Criteria for exclusion of cycles from the PP analysis of bleeding patterns will be defined 
in the statistical analysis plan (SAP) based on specific protocol deviations thought to have a 
potential to impact the subjects bleeding patterns that occurred during that cycle. Vaginal 
bleeding will be classified as spotting or bleeding and scheduled and unscheduled based on the 
definitions in Table 1.  
There will be two types of reference periods (RP) evaluated for this study: 
 Reference period based on 28-days (or cycle) – 13 cycles 
 Reference period based on 91 days  
The analysis will include all subjects in the respective analysis population with at least 1 
evaluable reference period.  One or two consecutive days with missing bleeding information 
will be interpolated with the bleeding information from the previous day.  For three or more 
consecutive days with missing bleeding information, missing data will be interpolated using 
the worst bleeding observation of the bordering days. 
Summaries of bleeding/spotting data include but are not limited to the following: 
 Number and percentage of subjects with unscheduled bleeding and/or spotting 
episodes for each reference period.

 Percentage of subjects with bleeding and/or spotting including both scheduled and 
unscheduled for each day presented in a graphical display. 
 Number and percentage of subjects with absence of any bleeding or spotting for each 
reference period. 
 Descriptive statistics (e.g., mean, SD, median, minimum, and maximum) for the 
number of days of bleeding and/or spotting, bleeding only, and spotting only within a 
reference period for: 
o Total Days (Unscheduled + Scheduled) 
o Unscheduled Days 
o Scheduled Days 
Additionally, bleeding data may be summarised for some subgroups specified in Section 
12.4.3.  
12.6.2 
Disposition 
The disposition of subjects will be summarized including the number of subjects screened, 
enrolled, treated, discontinued (including reason for discontinuation) and completed. In 
addition, the number of subjects included in each of the analysis populations will be 
summarized. The cumulative discontinuation rate, as determined by life-table methods, 
together with the corresponding 95% CIs will be presented.   
12.6.3 
Demographic and Other Pre-treatment Characteristics 
Subject demographic as well as medical history will be summarized for each analysis 
population using descriptive statistics for continuous variables and frequency distributions 
(number and percentage of subjects) for categorical variables.  Summaries will be provided 
overall and by race and BMI categories in the Safety/ITT and PP populations. 
 
12.6.4 
Prior and Concomitant Medications 
Medication usage will be coded using the World Health Organization (WHO) Drug Dictionary. 
Medications will be presented by WHO Drug Anatomical/Therapeutic/Chemical category and 
WHO Drug preferred name. Summaries will be presented for prior (prior to treatment period) 
medication use and concomitant (during treatment period) medication use. 
Medications with an end date occurring before the first investigational product dose date in the 
treatment period will be identified as prior medications.  Medications with a start date 
occurring on or after the first investigational product dose date in the treatment period or 
medications with a start date prior to the first investigational product dose date and an end date

on or after the first investigational product dose date will be identified as concomitant 
medications. All summaries will present the number and percentage of subjects for each 
medication. The denominators for calculating the percentages will be based on the number of 
subjects in the Safety population. 
12.6.5 
Treatment Compliance 
Treatment compliance by cycle will be presented using the subject diaries based on number of 
tablets taken divided by the number of tablets that should have been taken. The number and 
percentage of subjects missing no tablets, 1 tablet, 2 tablets and more than 2 tablets will be 
summarized for each cycle. Summaries will be presented using descriptive statistics in the 
Safety population. 
12.6.6 
 Protocol Deviations 
The number and percentage of subjects who had an important protocol deviation will be 
summarized for the enrolled population. 
12.6.7 
Quality of Life 
The total score of the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form 
(Q-LES-Q-SF) (Appendix 5) will be derived by summing the first 14 items to obtain the raw 
total score, which is then transformed into a percentage maximum using the following formula: 
(raw score – 14)/56. The absolute values and change from baseline of the percentage 
maximum, how satisfied the subject has been with the medication and how would the subject 
rate the overall life satisfaction and contentment during the past week will be summarized 
descriptively by visit. 
The Menstrual Distress Questionnaire will be scored according to the manual (Appendix 6) 11. 
The absolute values and change from baseline for the scores for pain, water retention, 
autonomic reactions, negative affect, impaired concentration, behaviour change, arousal and 
control will be summarized descriptively by visit. Summaries will be provided overall and by 
switchers and starters separately. 
12.6.8 
Follow-Up Evaluations 
The number and percentage of subjects who had pregnancy confirmation, returned to menses 
and received a new contraceptive method after the treatment termination will be summarized. 
The denominator used for the percentages will be the number of subjects in the Safety 
population who discontinued study medication due to a pregnancy wish. 
The time from last dose of study medication to return of menses will be summarized using 
descriptive statistics in the Safety population.

13 STUDY MANAGEMENT 
13.1 Monitoring 
The Investigator will be responsible for preparing and maintaining adequate and accurate 
source documents (medical records, raw data collection forms, etc.) designed to record all 
observations and other pertinent data for each subject treated with the study drug.  The 
Investigator will allow representatives of the Sponsor, contract Designees, authorized 
regulatory authority inspectors, and the ECs to have direct access to all documents pertaining 
to the study.  The Investigator is to immediately notify the Sponsor (or its representative) of 
any regulatory authority inspections.  The Investigator will be informed about the outcome of 
any Sponsor audit. 
This study will be monitored regularly, by or under supervision of a monitor from the Sponsor’ 
representative.  The frequency of monitoring visits will be agreed upon by the Sponsor’s 
representative and the study staff.  
Monitoring visits will take place on a regular basis according to the enrollment rate and number 
of subjects enrolled at each investigational site.  During these visits, the monitor will check the 
completion of the eCRF entries, compliance with the study protocol and with GCP - ICH, and 
their agreement with the source data.  The monitor will also verify the correct use of the study 
drug.  At a final visit, the monitor will check all remaining material including the remaining 
quantities of the study drug and will organize their return to the Sponsor or Designee.  At each 
visit, the Investigator and staff will be expected to cooperate with the Sponsor’s 
representative(s) for the purposes of review and verification of protocol compliance, AE 
reporting, eCRFs, source documents, clinical supplies and inventory records, and any 
additional records as may have been previously arranged between the Investigator and the 
Sponsor’s representative(s). 
The Investigator and/or other designated study personnel are expected to contact the Sponsor’s 
representative with any study concerns and/or questions. Contact details are provided in the 
Site Operations Manual for the site. 
13.2 Protocol amendments 
The Sponsor may propose to amend this protocol at any time. 
No change to the protocol will be implemented until the Sponsor, the competent authorities 
and the EC have reviewed and approved the amendment. 
In the event of an emergency, the Investigator shall implement any medical procedures deemed 
appropriate for subject safety.  All such procedures must have written documentation and be 
promptly reported to the Sponsor.

Page 74 of 155 
13.3 Protocol deviations 
A protocol deviation is any change, divergence or departure from the EC approved protocol 
(intentional or unintentional).  All deviations are to be documented at the site and reported to 
the EC according to the EC’s guidelines. 
In the event of an emergency, the Investigator shall implement any medical procedures deemed 
appropriate for subject safety. All such procedures must have written documentation and be 
promptly reported to the Sponsor.   
13.4 Withdrawal of Subjects 
Withdrawn subjects are those who do not complete all evaluations and procedures outlined in 
the protocol.  Subjects who discontinue taking study drug for any reason must also be 
withdrawn from the study. Subjects may be withdrawn from the study because of one of the 
following: 
 Adverse Event: An AE that, in the opinion of the Investigator or Sponsor, suggests 
that continued participation in the study is not in the subject’s best interest for safety 
reasons.  The occurrence of a VTE or an arterial thromboembolic event will 
automatically lead to the immediate cessation of the study drug and is an absolute 
reason for discontinuing the subject participation in the trial. Only 1 AE can be 
noted to be the reason for withdrawal.  All AEs that are present when the subject 
withdraws from the study will be followed as described in Section 9.6.3.1. 
 Lost to Follow-up: Confirmed at minimum by two phone calls and a traceable letter 
without answer. 
 Subject Request: Subject requests for any reason to be withdrawn or withdraws her 
consent. 
 Protocol Deviation: A subject may be withdrawn from the study at the discretion 
of the Investigator or Sponsor due to poor compliance with protocol requirements 
that may compromise the study results or subject safety. 
 Pregnancy: If a subject becomes pregnant during the study, the subject will be 
withdrawn from the study and followed through conclusion of the pregnancy. 
 Pregnancy wish. 
 Other: Other reasons include but are not limited to: Investigator decision that it is 
in the subject’s best interest to be withdrawn, administrative reasons, relocation of 
subject, etc.   
If a subject is withdrawn from the study after enrolment visit (Visit 2), all Visit 7 assessments 
should be completed during the Early Termination Visit (see Section 9.5.4) and the subject 
should be counseled about alternative contraception to use (see Section 9.6.4.8). Subjects 
withdrawn from the study will not be replaced.

13.5 Termination of the Study 
If the study is terminated prematurely or suspended, the appropriate EC and regulatory 
authority(ies) will be promptly informed of the termination or suspension and will be provided 
the reason(s) for the termination or suspension.  All obligations and responsibilities of the 
Sponsor and the Investigator under GCP, the US CFR and the Declaration of Helsinki will 
remain in force if the study is terminated prematurely.

14 DOCUMENTATION REQUIREMENTS AND RECORDKEEPING 
14.1 Source Documentation, Data access and Monitoring 
The eCRFs represent a record of the subject’s experience in the study, therefore, the eCRF data 
must be supported by original (or source) medical records, as appropriate. EMR (Electronic 
Medical Records)  recorded directly into the eCRF is also considered source data when there 
are no other written or electronic records preceding the eCRF entry. 
Prior to enrolling a subject in the study, the Investigator must document his/her review of 
subject eligibility criteria in the source records for the subject, including the Investigator’s 
signature and date on any medical and laboratory reports indicating a review of the source data 
occurred.  The Investigator will continue to follow this practice for any subsequent medical 
and laboratory reports generated as a result of the clinical study. 
The Investigator agrees that the Sponsor or its designated agents, the EC, the EMA, FDA or 
foreign regulatory agencies will have reasonable access to study source documentation for 
purposes of audit or inspection and monitoring visit review both during and after completion 
of the study. Monitoring visits provide the Sponsor and Designee with the opportunity to 
evaluate the progress of the study; to verify the accuracy and completeness of eCRFs; to ensure 
that all protocol requirements, applicable regulations and Investigator's obligations are being 
fulfilled; and to resolve any inconsistencies in the study records.   
14.2 Data Capture in electronic CRFs and Discrepancy Management 
Site personnel will be responsible for the completion and correction of eCRFs according to the 
protocol and other instructions provided by the Sponsor or their Designee. The Investigator is 
responsible for ensuring the completeness and accuracy of the data as evidenced by the 
Investigator’s signature and date once the subject has completed the study and all required 
study data has been entered into the eCRF. Information recorded by the subject into a Diary 
Card will be entered into the eCRFs by the site personnel.   
Since site personnel will enter data directly into a validated eCRF, programmatic data 
validation procedures will be employed to identify data discrepancies to site personnel at the 
time of entry and/or upon saving the data.  Designated site personnel will resolve any 
discrepancies via the eCRF.  Any additional findings upon clinical review by the Sponsor or 
their Designee will be entered into the system for review and resolution by site personnel.  A 
full audit trail of data changes following entry will be captured during the study in the 
electronic data management system.  The Investigator will be provided with a copy of all eCRF 
data for retention. 
14.3 RECORD KEEPING 
In compliance with ICH guidelines, the Investigator shall maintain adequate records for the 
study including copies of eCRFs for individual subjects, medical records, laboratory reports, 


 
 
  
Study MIT-Es0001-C301 
Amendment Final Version 2.1

consent forms, test article disposition records, safety reports, information regarding 
participants who discontinued and other pertinent data. The Investigator shall maintain these 
records for a period of at least 2 years after the last approval of a marketing application in an 
ICH region and until there are no pending or contemplated marketing applications in an ICH 
region, or at least 2 years have elapsed since the formal discontinuation of clinical development 
of the test article. These records should be retained for a longer period if required by the 
applicable regulatory requirements or by an agreement with the Sponsor. The Sponsor will 
inform the Investigator/institution as to when these records no longer need to be retained.

15.1 Financing and Insurance 
Financing and insurance is addressed in a separate agreement. 
15.2 Publication and Disclosure Policy 
The data that will be obtained in this study will be the property of the Sponsor, who will make 
reasonable efforts to assure that the results are published in a peer-reviewed journal. As some 
of the information concerning the investigational product and development activities at the 
Sponsor may be of strictly confidential nature, any manuscript or other presentation of data 
must first be reviewed by the Sponsor before its submission.

5 DEFINITION OF THE TERMS 
Barrier 
Contraception 
Birth control methods which physically block or otherwise prevent 
sperm from entering the uterus and reaching the egg for fertilization. 
It includes, including spermicides, sponges, condoms, diaphragms, 
and cervical caps. 
On-treatment 
pregnancy 
On-treatment pregnancies are pregnancies with an estimated date of 
conception within the in-treatment period i.e. Day 1 to 2 days after the 
last intake of investigational product (whether active or inactive

Pearl Index 
The Pearl index is the most common technique used in clinical trials 
for reporting the effectiveness of a birth control method. 
It is defined as the number of pregnancies per 100 woman-years of 
exposure: 
𝑃𝑒𝑎𝑟𝑙 𝐼𝑛𝑑𝑒𝑥
=
1300 ×  number of "on −treatment" pregnancies
number of women −𝟐𝟖−𝒅𝒂𝒚 𝒆𝒒𝒖𝒊𝒗𝒂𝒍𝒆𝒏𝒕 𝒄𝒚𝒄𝒍𝒆𝒔 of treatmen

7 INTRODUCTION 
7.1 Background 
[…] 
The potent synthetic estrogen, ethinyl estradiol (EE), is the most frequently used estrogen in 
COCs. EE is associated with a very easily observed when administered orally. Products 
containing EE generally have a good bleeding profile; however EE is but also responsible 
for with most of the side effects experienced by COC users.

[…] 
To improve the safety profile of COCs, research and development has focused on two main 
approaches. First, the dose of EE has been progressively lowered from > 75 µg to as low as 10 
µg. As EE doses decrease, the incidence of irregular and potentially A further decrease in 
the amount of EE may be associated with an unacceptable bleeding profiles increases. The 
second approach has been to replace EE with a naturally occurring estrogen: new COCs 
containing estradiol (E2) or estradiol valerate (E2V) have recently been developed, with the 
prospect of decreasing potential to decrease the metabolic impact from the estrogen 
component of COCs.   
Estetra SPRL is developing a new COC containing a synthetic form of a the natural estrogen, 
estetrol (E4), in association with drospirenone (DRSP), a well-characterized and widely used 
contraceptive progestin. E4 is only produced by the human fetal liver during pregnancy and 
reaches the maternal circulation through the placenta. E4 has been isolated in maternal urine 
as early as week 9 of gestation. At term, the hormone is found at relatively high concentrations 
(about 1 ng/mL) in maternal plasma and over ten times higher in fetal plasma. DRSP is a 
widely used contraceptive progestin in combination with EE.    
 
7.2 Prior Clinical Experience 
Estetrol  
In two Phase 1 clinical studies (PR3050 and PR3054) performed in healthy postmenopausal 
women, E4 was associated with a good safety and tolerability profile when it was taken orally 
up to 100 mg as a single dose up to 100 mg and as daily multiple doses up to 40 mg during 
28 consecutive days. Oral intake of multiple rising doses of E4 demonstrated an anti-
gonadotropic activity characterized by a dose-dependent decrease in both FSH and LH levels. 
This study also documented a significant increase in endometrial thickness in accordance with 
E4’s estrogenic actions.  
[…] 
Estetrol/Drospirenone 
[…] 
Data from ES-C01 showed that 5 and or 10 mg E4 associated combined with 3 mg DRSP 
administered in a 24/4-day regimen for three treatment cycles exert a complete inhibition of 
ovulation1during three treatment cycles. Ovarian activity decreases with increasing dose of E4. 
In addition, very limited to no impact on hepatic metabolism was observed with the E4/DRSP 
combinations as demonstrated by measurement before and after three treatment cycles of 
triglycerides2 and surrogate markers of hemostasis such as D-dimer, Prothrombin fragment 
1+2, inhibitors of coagulation (Active Protein C [APC] sensitivity, antithrombin III, APC 
resistance, protein S activity), liver factors (fibrinogen and prothrombin), endothelial factors

(E-selectin and tissue-type plasminogen activator [tPA]) and carrier proteins (corticosteroid 
binding globulin [CBG], sex hormone binding globulin [SHBG] and ceruloplasmin)2.  
Decrease from baseline in the carrier proteins was already visible noted after one cycle of 
treatment. This These findings suggest that there is limited impact of the E4/DRSP 
combination on the coagulation pathway.  
The combination of 3 mg DRSP with either 15 mg E4 or 20 mg E4 administered in a 24/4-day 
regimen was evaluated in the ES-C02 study, a six- treatment cycle treatment study focusing 
on vaginal bleeding pattern and cycle control. A high rate of expected withdrawal bleeding 
(96.5%) and a low incidence of unscheduled bleeding/spotting episodes (16.9%) of 
unscheduled bleeding episodes) were observed with the 15 mg E4/3 mg DRSP combination.  
In addition, the E4/DRSP combinations demonstrated a good safety and tolerability profile. A 
low frequency of adverse events (AEs) with the 15 mg E4/3 mg DRSP combination was 
recorded and all AEs were similar to those classically observed with COCs. Finally, no 
ovulations were observed during this study demonstrating the potential for high contraceptive 
reliability of the E4/DRSP combinations studied. 
A low frequency of adverse events (AEs) with the 15 mg E4/3 mg DRSP combination was 
recorded and all AEs were similar to those classically observed with COCs. From the different 
studies performed so thus far with E4, it can be concluded that a E4-containing used in a COC 
is well tolerated. No safety concern was observed with any E4 combination. However, until 
further evaluation in larger populations, the classical COCs contraindications will apply to the 
15 mg E4/3 mg DRSP combination.

9 INVESTIGATIONAL PLAN 
9.1 Overall Study Design and Plan 
[…] 
The total duration of the study, including the screening, will range from 392 382 to 399 447 
days for the participating subjects, which is approximately a year and one month. Those 
subjects who discontinue due to a pregnancy wish will be followed-up for a maximum of one 
year after study treatment termination discontinuation for return of spontaneous 
menstruation and until pregnancy, return of spontaneous menstruation or initiation of a 
contraceptive method (whichever occurs first).  
Approximately 1550 healthy female subjects at risk for pregnancy, between 18 and 50 years 
old (inclusive, at the time of screening), and requesting contraception will be enrolled in the 
study. […] 
The general safety will be evaluated by the determination of routine laboratory parameters, 
vital signs, cervical smears, by performing physical, gynecological and breast examinations 
and by recording number, frequency, type and intensity of AEs and serious adverse events 
(SAEs).  
[…] 
Treatment compliance will be assessed using data from the subject diary across the entire study 
and by cycle. The subject diary will also be used to determine whether or not a cycle is 
evaluable at risk for the Pearl Index calculation. 
Subjects’ Physical, psychological and social functioning and well-being associated with the 
investigational product will be assessed with validated well-established questionnaires.

 At Visits 2, 3, 4, 5 and 6 for subjects who reported a change in sexual partner since 
the last study visit. 
  
In case of positive Chlamydia test result, the subject will be treated, at the Investigator’s 
discretion, before enrollment as this infection can influence the vaginal bleeding pattern. In 
case of positive Chlamydia test result at screening, the subject will start treatment before she 
is enrolled. 
A gonorrhea testing will be performed using a vaginal swab:

available and the subject meets entry criteria. A copy of any Pap test or follow-up testing 
used for determination of study eligibility or during study follow-up must be obtained and 
included in the study record.  If not available at the time of the visit for which the 
documentation is required then the Pap test should be performed per protocol. The results 
of the Pap smear test will be reported using the Bethesda Pap Smear Classification as detailed 
in Appendix 3. If the Pap smear test at the Screening Visit presents abnormal result (i.e. 
dysplasia, cervical intraepithelial neoplasia, squamous intraepithelial lesion, carcinoma in situ, 
invasive carcinoma), the subject cannot be enrolled in the study.  Enrollment of a subject with 
an ASC-US interpretation will not be permitted. is permitted if the subject is less than 21 years 
of age or HPV reflex test is negative for high-risk oncogene virus. If the ASCUS 
interpretation was done on the Pap test performed in the past 18 months, enrollment of the 
subject is allowed if a repeat Pap test 6 months later was normal.

The endometrial tissue obtained by endometrial biopsy will be processed by a central 
laboratory. An Two independent pathologists will assess the slides from the endometrial 
biopsies. In case of abnormal pathological findings, the slide may be submitted to one 
additional pathologist to confirm the diagnosis. In case of discrepancy between both 
pathologists’ assessments, a third independent pathologist will assess the slide. If concurrence 
is not reached, the worst diagnosis will be used. Detailed procedures for obtaining endometrial 
biopsies, tissue preparation and endometrial biopsy assessment will be described in separate 
study manuals to be provided to the sites.

9.6.4.11 Return of spontaneous menstruation and return to fertility 
Return of fertility after study treatment will be assessed in subjects who discontinue the study 
due to a pregnancy wish. They will be contacted, by phone, every 6 weeks for a maximum of 
one year after study treatment termination until pregnancy, return of spontaneous menstruation 
or initiation of a contraceptive method (whichever comes first). This follow-up will anyhow 
stop at the time of Data Base Lock of the study.  
The return of fertility information (date of pregnancy confirmation or date of return of 
menses or date of new contraceptive method) will be recorded in  the eCRF.  
 
Each woman who discontinue the study due to a pregnancy wish will be followed-up after 
study treatment discontinuation to evaluate return of spontaneous menstruation and return 
of fertility.

They will be contacted by phone every 6-8 weeks for a maximum of one year after study 
discontinuation. The date of the first spontaneous menstruation after study discontinuation 
will be recorded in the eCRF and follow-up will be continued. Once a pregnancy is reported 
or once a new contraceptive method has been started, the expected date of pregnancy term 
or of contraceptive treatment initiation will be recorded in the eCRF and no further follow-
up contact will be done. In case of pregnancy, the estimated date of conception will be 
derived from the expected date of pregnancy term. 
 
12 PLANNED STATISTICAL METHODS 
[…] 
12.1 Determination of Sample Size 
[…]  Assuming that the true Pearl Index is 1.0 and that a Poisson model is used to derive the 
CIs, then at least 12,337 evaluable at risk cycles are required for a power of 90% in the 18 to 
35 year old population9..  If an unevaluable a not at risk cycle rate of 10% and a dropout rate 
of approximately 30% (assuming that we have an average of 4 cycles for subjects that 
discontinue) are assumed, approximately 1350 18-to-35 year old subjects need to be enrolled.   
[…] 
12.2 Analysis Populations and Datasets 
[…] 
 Per-protocol (PP) population includes all subjects in the ITT population who complete 
the study and do not have any important protocol deviations that impact the statistical 
analysis. The PP population may differ for the different endpoints. 
 
12.4 Efficacy Analyses 
The efficacy analysis will be based on the Pearl Index. The Pearl Index, defined as the 
number of pregnancies per 100 women-years of treatment, will be calculated as 
𝑃𝑒𝑎𝑟𝑙 𝐼𝑛𝑑𝑒𝑥=
1300 ×  number of on −treatment pregnancies
number of women −𝟐𝟖 𝒅𝒂𝒚 𝒆𝒒𝒖𝒊𝒗𝒂𝒍𝒆𝒏𝒕 cycles of treatment 
Only evaluable at risk cycles, i.e. cycles in which no other methods of birth control (including 
condoms) are used and during which the subjects confirmed that sexual intercourse has 
occurred, will be included in the denominator of the Pearl Index calculation.

On-treatment pregnancy is defined as pregnancy with an estimated date of conception within 
the on-treatment period, i.e. Day 1 to 2 days after the intake of investigational product (whether 
active or inactive tablet). In cases where the date of conception cannot be established 
unequivocally (e.g. subjects is lost to follow up), this pregnancy will be considered an on-
treatment pregnancy. For calculation purposes a cycle will be defined as 28 days.

12.4.1 Efficacy Endpoints 
The efficacy endpoints are: 
 […]; 
 
Method failure Pearl Index for subjects aged 18 to 35 years old, inclusive, at screening; 
 […]. 
 
The primary efficacy endpoint will be the Pearl Index in the ITT population aged 18 to 35 
years inclusive at Screening with evaluable at risk cycles (cycles in which no other methods 
of birth control (including condoms) are used and during which the subjects confirmed that 
sexual intercourse has occurred). Subjects in this age group will not be censored on their 36th 
birthday for the pregnancy assessment. 
12.4.2 Statistical Analysis 
12.4.2.1 Confidence Intervals for the Pearl Indices 
The 95% CI for the Pearl Indices will be presented for the 18 to 35 year age group and overall 
and for method failure for the ITT population including only at risk cycles in the denominator. 
For historical comparison the Pearl Index will also be calculated using the same method as 
described above including all at risk cycles and cycles where the subject did not have 
intercourse and did not use backup contraception in the denominator.

9.5.4 Early Termination Visit  
In case of early termination or withdrawal of subject (see Section 13.5), the procedures listed 
in Visit 7 (see Section 9.5.3.5) will be performed and Treatment Discontinuation Form will be 
completed. In addition, the subject will be counseled about the next contraceptive method to 
use (see Section 9.6.4.9). 
A subject who desires early termination or is withdrawn from the study after the enrollment 
visit (Visit 2) (see Section 13.4) will require an Early Termination Visit. 
 Any subject should be instructed at each visit to contact the study staff before 
discontinuing the study drug to be counseled about alternative contraception to use 
prior to the Early Termination Visit (see Section 9.6.4.8).  Study sites may provide 
any prescription or non-prescription contraceptive to the subject as is medically

appropriate per local standard of care other than an IUD or implant. If necessary, 
an unscheduled visit can occur to provide contraception (see Section 9.5.5). 
 A subject who presents to the study site for a scheduled visit and desires to 
discontinue study participation or is withdrawn from the study at that visit should be 
counseled about alternative contraception to use prior to the Early Termination Visit 
(see Section 9.6.4.8). Study sites may provide any prescription or non-prescription 
contraceptive to the subject as is medically appropriate per local standard of care 
other than an IUD or implant. 
 A subject who presents to the study site for a scheduled visit who has not taken the 
study product for 11 days or more should have the scheduled visit procedures and 
the Early Termination Visit procedures completed at that time. The subject should 
be counseled about alternative contraception (see Section 9.6.4.8). Study sites may 
provide any prescription or non-prescription contraceptive to the subject as is 
medically appropriate per local standard of care. 
An Early Termination Visit should occur between 11 and 18 days after the last 
investigational product intake or immediately if the investigational product was never 
started. The procedures listed in Visit 7 (see Section 9.5.3.6) will be performed and the End 
of Study Form will be completed.  
[…] 
9.5.5 Unscheduled Visit 
At any time of the study, an Unscheduled Visit could occur in case of suspicion of pregnancy 
based on a positive pregnancy test performed at home by the subject or, in case the Investigator 
judges it necessary to examine a subject who would present a potential significant adverse 
event in the Investigator’s opinion, or if alternative contraception is needed for a subject 
planning early termination. Additional assessments can be performed at the Investigator’s 
discretion. 
9.6.2 Efficacy assessments 
 9.6.2.2 Pregnancy Reporting 
[…] 
All on-treatment pregnancies identified during the course of the study in a subject who was 
using the investigational product will be monitored to completion, i.e., approximately 9 month 
follow-up in the case of live birth or until outcome information is obtained. […]. 
If a subject becomes pregnant and states she never started the investigational product, the 
pregnancy does not have to be monitored if the subject returns all of the investigational 
product (proving she never started the investigational product).

9.6.4 Other Evaluations 
9.6.4.8 Contraceptive counseling 
At Visit 6 and at the Early Termination Visit in case of premature study termination, the 
subject will be counseled about her future contraception. The choice of the contraceptive 
method is left at to the Investigator’s discretion.  
A subject who desires early termination or is withdrawn from the study (see Section 13.4) 
after the enrollment visit (Visit 2) will be counseled about future contraception. 
 Any subject should be instructed at each visit to contact the study staff before 
discontinuing the study drug to be counseled about alternative contraception to use 
prior to the Early Termination Visit.  Study sites may provide any prescription or 
non-prescription contraceptive to the subject as is medically appropriate per local 
standard of care other than an IUD or implant. If necessary, an unscheduled visit 
can occur to provide contraception (see Section 9.5.5). 
 A subject who presents to the study site for a scheduled visit and desires to 
discontinue study participation or is withdrawn from the study at that visit should be 
counseled about alternative contraception to use prior to the Early Termination Visit. 
Study sites may provide any prescription or non-prescription contraceptive to the 
subject as is medically appropriate per local standard of care other than an IUD or 
implant. 
 
A subject who presents to the study site for a scheduled visit who has not taken the 
study product for 11 days or more should have the scheduled visit procedures and 
the Early Termination Visit procedures completed at that time. The subject should 
be counseled about alternative contraception. Study sites may provide any 
prescription or non-prescription contraceptive to the subject as is medically 
appropriate per local standard of care.

The baseline questionnaires will be given to the subject at Visit 2. The subject will be instructed 
to fill them in at home on or before the first day of study medication intake (Day 1). At the 
next visit, the study site personnel will ensure for the questionnaire completion. 
9.6.4.12 Return of spontaneous menstruation and return to fertility 
Each woman who discontinues the study early due to a pregnancy wish will be followed after 
study treatment discontinuation to evaluate return of spontaneous menstruation and return of 
fertility.  
They will be contacted by phone every 6-8 weeks for a maximum of one year after study 
discontinuation.

STUDY MANAGEMENT 
13.4 Withdrawal of Subjects 
[…] 
If a subject is withdrawn from the study following the start of study drug after enrolment visit 
(Visit 2), all Visit 7 assessments should be completed during the Early Termination Visit (see 
Section 9.5.4) and the subject should be counseled about alternative contraception to use 
(see Section 9.6.4.8). Subjects withdrawn from the study will not be replaced.

1.0 Introduction 
This statistical analysis plan (SAP) describes the statistical methods to be used during the reporting and 
analyses of data collected under Estetra Protocol MIT-Es0001-C301.  
This SAP should be read in conjunction with the study protocol and case report form (CRF). This version 
of the plan has been developed using the protocol amendment 2.1 dated 6 February 2017 and CRF dated 
10 April 2018. Any further changes to the protocol or CRF may necessitate updates to the SAP. 
2.0 Study Objectives 
2.1 Primary Objective 
The primary objective of this study is to evaluate the contraceptive efficacy of 15 mg Estetrol (E4)/3 mg 
Drospirenone (DRSP) using the Pearl Index in subjects aged 18 to 35 years, inclusive, at the time of 
screening. 
2.2 Secondary Efficacy Objectives 
The secondary objectives of this study are: 
1. To evaluate the contraceptive efficacy of 15 mg E4/3 mg DRSP using the method failure Pearl 
Index and life-table analysis in subjects aged 18 to 35 years, inclusive, at the time of screening 
2. To evaluate the contraceptive efficacy of 15 mg E4/3 mg DRSP using the Pearl Index, the method 
failure Pearl Index and life-table analysis in the overall study population 
2.3 Other Secondary Objectives 
1. To evaluate cycle control and bleeding pattern associated with 15 mg E4/3 mg DRSP 
2. To evaluate general safety of 15 mg E4/3 mg DRSP 
3. To evaluate the endometrial safety using histological assessment of endometrial biopsy samples 
in a subset of subjects aged 18 to 50 years, inclusive, at the time of screening (endometrial safety 
Substudy) 
4. To evaluate the impact of 15 mg E4/3 mg DRSP on physical, psychological, and social functioning 
and well-being 
3.0 Study Design 
This study is a multicenter, open-label, single-arm study. 
The total duration of the study, including the screening, will range from 382 to 447 days for most of the 
participating subjects, which is approximately 13 months. Those subjects who discontinue and desire 
pregnancy will be followed for a maximum of one year after study discontinuation for return of spontaneous 
menstruation, until pregnancy, or until initiation of a contraceptive method (whichever occurs first). 
Approximately 1550 healthy female subjects at risk for pregnancy, between 18 and 50 years old (inclusive, 
at the time of screening), and requesting contraception will be enrolled in the study. In total 1350 subjects 
will be 18 to 35 years old (inclusive). Recruitment may be stopped when 1550 subjects have been enrolled 
if the required number of subjects for the primary analysis (1350 subjects in the age group up to 35 years) 
has been reached. Recruitment in the age group > 35 years will be stopped when 200 subjects have been 
enrolled. 
Eligible subjects will be treated with 15 mg E4/3 mg DRSP for 13 consecutive cycles. The treatment must 
be taken once daily at approximately the same time of the day in a 24/4-day regimen, i.e. 24 active tablets 
followed by 4 placebo tablets (4-day hormone free interval).

The primary objective of the study is to evaluate the contraceptive efficacy of the new Combined Oral 
Contraceptive (COC), using the Pearl Index (which reflects the pregnancy rate associated with a 
contraceptive method) among the subjects aged 18 to 35 years inclusive. 
The contraceptive efficacy will also be evaluated using the method failure Pearl Index (which reflects the 
pregnancy rate due to method failure only) and life-table analysis in the subjects aged 18 to 35 years 
inclusive and in the overall study population. 
The general safety will be evaluated by the determination of routine laboratory parameters, vital signs, by 
performing physical, gynecological and breast examinations and by recording number, frequency, type and 
intensity of adverse events (AEs) and serious adverse events (SAEs). 
Endometrial safety will be evaluated using histological assessments of endometrial biopsy samples. 
Participating subjects will be asked to record daily in a subject diary their bleeding/spotting episodes. This 
will allow evaluating the bleeding pattern and the cycle control associated with the investigational product. 
Treatment compliance will be assessed using data from the subject diary across the entire study and by 
cycle. The subject diary will also be used to determine whether or not a cycle is an at risk cycle for the Pearl 
Index calculation. In the primary analysis of the Pearl Index, at risk cycles will be defined as cycles in which 
the following criteria are met: 
1. No other methods of birth control (including condoms) are used by the subject as confirmed in the 
subject diary  
2. The subject confirmed that sexual intercourse occurred during the cycle in the subject diary 
Note that if conception occurs in a cycle, then that cycle will be included as an at risk cycle in the 
denominator even if any other contraceptive method was used during that cycle or the subject did not 
confirm that sexual intercourse occurred. Cycles after the cycle of conception will not be included as at risk 
cycles and will be excluded from the denominator. 
Physical, psychological and social functioning and well-being associated with the investigational product 
will be assessed with well-established questionnaires. A study schedule of events is provided in Appendix 1 
of the Protocol.  
3.1 Sample Size Considerations 
Sample size is based on needing a sufficient number of cycles such that the difference between the Pearl 
Index and the upper limit of the two-sided 95% confidence interval (CI) for the Pearl Index does not exceed 
1. Assuming that the true Pearl Index is 1.0 and that a Poisson model is used to derive the CIs, then at 
least 12,337 at risk cycles are required for a power of 90% in the 18 to 35 year old population (Gerlinger et 
al., 2003). Assuming a not at risk cycle rate of 10% and a dropout rate of approximately 30% (assuming an 
average of 4 cycles for subjects that discontinue), approximately 1350 18-to-35 year old subjects need to 
be enrolled. Additionally, it is planned to enroll a maximum of 200 subjects 36-50 years. Therefore, in total, 
approximately 1550 subjects will be enrolled in the study. 
No formal sample size has been estimated for the endometrial safety sub-study. 
Approximately 100 subjects with both a Screening and Visit 7a biopsies are planned to be included in the 
endometrial safety sub-study. Assuming a 40% dropout rate for a 13-cycle treatment will yield 
approximately 167 subjects who will have a screening biopsy performed at selected sites.  
4.0 Study Variables and Covariates 
4.1 Primary Variable 
The primary efficacy variable will be the number of on-treatment pregnancies assessed by the Pearl Index 
in the ITT population aged 18 to 35 years, inclusive, at the time of screening with at risk cycles (cycles in

which no other methods of birth control (including condoms) are used and during which the subjects 
confirmed that sexual intercourse has occurred). 
4.2 Secondary Variables 
4.2.1 Efficacy 
The secondary efficacy variables are: 
1. The number of on-treatment pregnancies as assessed by the method failure Pearl Index and the 
cumulative pregnancy rate in subjects aged 18 to 35 years, inclusive, at the time of screening 
2. The number of on-treatment pregnancies as assessed by the Pearl Index, the method failure Pearl 
Index and the cumulative pregnancy rate in the overall study population 
4.2.2 Other Secondary Variables 
The other secondary variables are: 
1. Cycle control and bleeding patterns based on vaginal bleeding information recorded daily by the 
subjects in the diaries 
2. Safety data in the overall study population obtained from routine laboratory parameters, vital signs, 
and physical, gynecological and breast examinations, evaluated as the number, frequency, type 
and intensity of AEs and SAEs  
3. Change in endometrial histology from baseline to end of treatment in subjects having been treated 
for at least 10 complete cycles 
4. Change from baseline to end of treatment in the various items of well-established questionnaires 
to evaluate physical, psychological, and social functioning and well-being 
4.3 Predetermined Subgroups 
The key subgroup in this study is subjects aged 18 to 35 years, inclusive, at the time of screening. This 
subgroup is used for the primary efficacy population. All data regarding disposition, baseline characteristics, 
compliance, exposure and contraceptive efficacy will be presented for subjects aged 18 to 35 years and for 
all subjects within the specified analysis population.  
In addition, subgroup analyses will be performed for the Pearl Index and vaginal bleeding data (specifically 
unscheduled bleeding and spotting and the absence of scheduled bleeding) for the following categories: 
 
Body Mass Index (BMI) categories (< 30, ≥ 30 kg/m2) at Baseline 
 
Race category (White, Black or African American, Asian, American Indian or Alaska Native, Native 
Hawaiian or other Pacific Islander, Other Race) 
 
Starters (including true new users)/Switchers (see Section 5.5) 
 
Smokers/Non-smokers at Baseline 
 
Age (≥ 18 to ≤ 25; > 25 to ≤ 35 and > 35 years old) at Screening 
The non-smokers group includes subjects who are former smokers and never smokers. The smokers group 
includes subjects who are current smokers. The other race group includes subjects who selected more 
than one race, or whose race was recorded as other race on the CRF.  
Quality of life data will be presented for all subjects and for starters and switchers separately.

5.0 Definitions 
5.1 Cycle 
The expected duration of a cycle is 28 days. A 28-day cycle consists of 24 days of active tablet intake 
followed by 4 days of inactive tablet intake and subjects who complete the study are expected to have 
completed thirteen 28-day cycles. 
All cycles will be determined using the start dates recorded in the diaries. The first day of a cycle is the start 
date recorded on the diary for that cycle and the last day of a cycle coincides with the day before the start 
date recorded on the diary for the next cycle. For the last cycle (where no start date for the following cycle 
is available), the last day of the cycle will be assumed to be the date of last dose of study medication, 
whether this is an active or inactive tablet. The date of last dose of study medication in the last cycle will be 
derived from the data collected in the diary. 
If the conception is confirmed to be during a specific cycle in the narrative and this cycle is not in the diary 
data, then the cycle will be included as cycle in the exposure for the derivation of the Pearl Index.  If the 
cycle in which conception occurred is not known, cycle(s) up to the one in which the positive pregnancy 
occurred will be included in the exposure for the derivation of the Pearl Index. 
For the analysis of bleeding data, the cycle will be shifted by 3 days with the 3 days of the next cycle 
included in the previous cycle. For example, in the bleeding analysis Cycle 2 will be from Day 4 of Cycle 2 
to Day 3 of Cycle 3 inclusive.  
The start and stop times of a cycle will be determined before determining whether the cycle is evaluable for 
the Pearl Index or evaluable for the bleeding data. Data review meetings may be held to determine if cycles 
are at risk cycles for the Pearl Index and if they are evaluable for the bleeding analysis prior to database 
lock (see Section 8.3) if the classification is not clear from the data collected and the rules in the SAP.  
5.1.1 At Risk Cycle for Pearl Index  
In the primary calculation of the Pearl Index (see Section 9.5.1 for details) and the Method failure Pearl 
Index, only at risk cycles will be included in the derivation of the number of women-28 day equivalent cycles 
of treatment, which is used as the denominator. At risk cycles will be defined as cycles in which the following 
criteria are both met: 
1. No other methods of birth control (including condoms) are used by the subject as confirmed in the 
subject diary 
2. The subject confirmed that sexual intercourse occurred during the cycle in the subject diary 
This definition of at risk cycles will be used as the denominator for the Pearl Index for on-treatment 
pregnancies and also for on-treatment method failure pregnancies. 
Two alternative calculations of the exposure (i.e., the denominator) will be performed to allow for 
comparisons with historical data: 
 
All exposure, which includes cycles with and without other methods of birth control and cycles with 
and without sexual intercourse. In this derivation of the Pearl Index all cycles are classed as at 
risk cycles with the exception of any cycles after the cycle of conception in the case of pregnancy. 
This denominator will be used for the Pearl Index for on-treatment pregnancies only, 
 
Modified at risk exposure, where only cycles with other methods of birth control are excluded, while 
occurrence of sexual intercourse is not taken into account. In this derivation of the Pearl Index, at 
risk cycles are defined as cycles in which no other methods of birth control (including condoms) are 
used by the subject as confirmed in the subject diary.

Two additional alternative definitions of at risk cycles will be used for the derivation of the Pearl Index for 
method failure pregnancies. In the first of these definitions, cycles qualify if they meet all of the criteria 1 to 
8 listed below:  
1. No other methods of birth control (including condoms) are used by the subject as confirmed in the 
subject diary 
2. The subject confirmed that sexual intercourse occurred during the cycle in the subject diary 
3. A subject does not have a user failure pregnancy with an estimated conception date in that cycle 
or prior to that cycle and does not have a method failure pregnancy with an estimated conception 
date prior to that cycle  
4. The subject does not receive unauthorized concomitant medication (see section 9.4.6.1 of the 
protocol) for at least one day during the cycle   
5. The subject does not miss 4 or more days of active pills during the cycle  
6. The subject does not miss 2 or more consecutive days of active pills during the cycle 
7. The length of the previous cycle is not longer than 28 days 
8. The subject had no adverse events of vomiting and/or diarrhea during the cycle 
In the second of these definitions, cycles qualify if they meet all of the criteria 1 and 3 to 8 listed above (i.e. 
occurrence of sexual intercourse is not taken into account),  
The following rules will be applied to all types of exposure:  
 
If conception occurs in a cycle, then that cycle will be included in the denominator, regardless of 
whether or not other methods of birth control were used during that cycle, or whether or not sexual 
intercourse was confirmed.  
 If the conception is confirmed to be during a specific cycle in the narrative and this cycle is 
not in the diary data, then the cycle will be included in the denominator, regardless of whether 
or not other methods of birth control were used during that cycle, or whether or not sexual 
intercourse was confirmed  
 The only exception is for user failure pregnancies, which will be excluded from the exposure 
definitions based on the compliance rules 3 to 8 above, since they do not meet criterion 3 
 
Cycles after the cycle of conception will be excluded from the denominator 
 
Missing data from the diary will be handled according to section 5.15.1. 
5.1.2 Evaluable Cycle and Reference Period for Bleeding Data  
Bleeding data will be analyzed by cycle and by reference period (RP). For the analysis of bleeding data by 
cycle, the cycle will be shifted by 3 days with the 3 days of the next cycle included in the previous cycle. 
For example, in the bleeding analysis Cycle 2 will be from Day 4 of Cycle 2 to Day 3 of Cycle 3 inclusive. 
For the 3 days after Cycle 13, the last non-missing response for bleeding in Cycle 13 will be imputed. 
In determining whether a cycle is evaluable for the bleeding analysis of a specific population, the cycle 
based on the diary data will be used rather than the shifted cycle used to present the data.  
For the ITT analysis, a cycle will be considered non-evaluable if: 
 
The length of the cycle is longer than 28 days.  
A cycle will be considered to be non-evaluable in the per-protocol (PP) analysis for bleeding data if any of 
the following criteria are met: 
1. A subject becomes pregnant in that cycle or prior to that cycle

2. The length of the cycle is shorter than 22 days or longer than 28 days  
3. A subject did not have a hormone-free period towards the end of the cycle (i.e. there are not at 
least 4 days where an active tablet was not taken between the last day an active tablet was taken 
in this cycle and the first day an active tablet was taken in the next cycle) 
4. The subject received unauthorized concomitant medication (see section 9.4.6.1 of the protocol) 
thought to have the potential to impact the bleeding analysis for at least one day during the cycle  
5. Use of unauthorized pre-treatment and concomitant medication thought to have the potential to 
impact the bleeding analysis, if cycle starts within 28 days after discontinuation of unauthorized 
medication 
6. The subject had a positive test for chlamydia or gonorrhea during that cycle 
7. The subject missed 4 or more days of active pills during the cycle 
8. The subject missed 2 or more consecutive days of active pills during the cycle 
9. The subject had a procedure to the vagina, cervix or endometrium during the cycle (for endometrial 
biopsy, please see below) 
10. The subject had an endometrial biopsy taken during that cycle  
a. If a subject had a biopsy at Screening, then any cycles that started in the 28 days after the 
biopsy date will be considered non-evaluable 
b. If a subject had a post treatment biopsy during the cycle or in the 28 days prior to the start 
of the cycle  
A cycle with missing diary bleeding data will still be considered evaluable if the criteria above are not met 
and bleeding data can be imputed for days with missing data (see Section 5.15.2 for details). 
Three other analyses of bleeding data will be performed as follows: 
1. Using cycles in which all active pills were taken as per the instructions in the protocol. In this 
analysis, evaluable cycles will be defined as per the PP analysis but cycles where there was at 
least 1 day between Day 1 and Day 24 where an active pill was not taken will be excluded. 
2. Using cycles in which exactly 1 active pill was missed. In this analysis, evaluable cycles will be 
defined as per the ITT analysis but only cycles where there was exactly 1 missed active pill between 
Day 1 and Day 24 are included. 
3. Using cycles in which at least 2 active pills were missed. In this analysis, evaluable cycles will be 
defined as per the ITT analysis but only cycles where there were at least 2 missed active pills 
between Day 1 and Day 24 are included. 
In addition, an analysis by RP will be performed where there are 4 RPs each of 91 days in duration defined 
as follows: 
 
RP1 = Day 1 to Day 91 
 
RP2 = Day 92 to Day 182 
 
RP3 = Day 183 to Day 273 
 
RP4 = Day 274 to Day 364 
where Day 1 is the first day of Cycle 1 reported in the subject diary and then the remaining days are fixed 
using Day 1 as a reference. For example, Day 91 is 90 days after the date of the first day of Cycle 1. 
A RP will be considered to be non-evaluable in the ITT analysis when the RP is less than 91 days in duration 
(i.e. where the subject withdraws from the study during the RP). If there are any gaps between cycles in 
terms of date within the RP (i.e. at the end of the 4-day inactive pill period of a given cycle, the subject does

not directly restart with the first active pill of the next pill pack), then the RP will be excluded from the ITT 
Population. For example, if Cycle 1 Day 28 is 1 February 2018 and Cycle 2 Day 1 is 3 February, then RP1 
will be excluded from the ITT.  
A RP with missing bleeding diary data will still be considered evaluable if the criteria above are not met and 
bleeding data can be imputed for days with missing data (see Section 5.15.2 for details).  
5.2 Baseline and Change from Baseline 
The Baseline value for each assessment is defined as the last measurement taken prior to first 
administration of study medication, unless otherwise stated. When the date of the assessment is on the 
date of first administration, it will be assumed that the assessment was performed prior to first dose. The 
Baseline value for the Menstrual Distress Questionnaire will be the value collected at Visit 3 because the 
date of completion is not collected in eCRF for this questionnaire. 
For any parameter at a specific visit, change from Baseline is calculated as the value of that parameter at 
that visit minus the Baseline value of that parameter, as defined above. 
5.3 On-Treatment Period 
For contraceptive efficacy, the On-Treatment Period is defined as the period of time between the date of 
first dose of study medication and 2 days after the last dose of study medication (regardless of whether this 
is an active or inactive table), inclusive.  
For safety (TEAEs and concomitant medication), the On-Treatment Period is defined as the period of time 
between the date of first dose of study medication and the date of last dose of study medication (regardless 
of whether this is an active or inactive table), inclusive.  
If the subject had a period of time when study medication was not being taken between the date of first 
dose of study medication and the last dose of study medication, this time will still be considered to be during 
the On-Treatment Period. 
5.4 Body Mass Index 
BMI in kg/m2 will be calculated using the following formula: 
BMI= weight
height2 
Weight and height collected on the CRF will not be rounded prior to deriving BMI. 
5.5 Switchers, Starters and True New Users 
Starters are defined as subjects who have not used hormonal contraceptives within the 3 months prior to 
the date of first dose of study medication. 
Switchers are defined as subjects who have used hormonal contraceptives within the 3 months prior to the 
date of first dose of study medication. 
True new users are defined as subjects who have never received a hormonal contraceptive. This group of 
subjects is a subset of the group of subjects classed as starters. 
5.6 Prior, Post-Study Treatment and Concomitant Medication Use 
Medications with an end date occurring before the date of first dose of study medication will be identified 
as prior medications.  
Medications with a start date occurring after the end of the safety On-Treatment Period will be identified as 
post-study treatment medications. 
The following medications will be identified as concomitant medications:

 
Medications with a start date during the safety On-Treatment Period (see Section 5.3 for details)  
 
Medications with a start date prior to the date of first dose of study medication and an end date on 
or after the date of first dose of study medication  
Any medications with a missing end date will be considered to be ongoing at the end of study treatment 
and thus would be assumed to be after the first dose of study medication and therefore assigned as a 
concomitant medication.  
5.7 Study Treatment Compliance 
Treatment compliance for the investigational product will be assessed based on the data collected in the 
subject diary.  
5.7.1 Compliance analysis by cycle  
In the compliance analysis by cycle, a cycle will only be included if there is a reported start date for that 
cycle. Prior to calculating any compliance data by cycle, cycles are first determined using the start date of 
the cycle and the start date of the next cycle, per the rules in Section 5.1. In the compliance analysis by 
cycle, only days within the cycle after those rules have been applied are included in the derivation of the 
endpoints in this Section by cycle. 
The treatment compliance will be calculated as a percentage and derived for each cycle that the subject 
started. For each cycle, the total number of pills (active or inactive) taken will be determined from the subject 
diary. If an entry of the number of active (pink) or inactive (white) pills is left blank in the diary, then it will 
be assumed that no pills were taken on that day. 
The compliance for a given cycle will be derived as  
100 𝑥 
𝑡ℎ𝑒 𝑡𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑝𝑖𝑙𝑙𝑠 𝑡𝑎𝑘𝑒𝑛 𝑑𝑢𝑟𝑖𝑛𝑔 𝑡ℎ𝑒 𝑐𝑦𝑐𝑙𝑒
𝑡ℎ𝑒 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑝𝑖𝑙𝑙𝑠 𝑒𝑥𝑝𝑒𝑐𝑡𝑒𝑑 𝑡𝑜 𝑏𝑒 𝑡𝑎𝑘𝑒𝑛 𝑑𝑢𝑟𝑖𝑛𝑔 𝑡ℎ𝑒 𝑐𝑦𝑐𝑙𝑒 
 
The number of pills expected to be taken during the cycle is derived as the end date of the cycle – start 
date of the cycle + 1 where the start and end dates of the cycles are determined using the rules in Section 
5.1. In the case of early termination from the study, in the last cycle for that subject, the number of pills 
expected to be taken during the cycle is calculated as the date of last dose of study medication – the start 
date of the cycle of interest + 1.  
In addition, the subject diary data will be used to identify when a pill has been missed. The number of 
missed pills will be derived for each cycle. In this situation, a pill is assumed to be missed if there is a day 
in the diary without an entry for the number of tablets or with 0 active and 0 inactive pills reported as taken. 
Any gaps between Day 28 of a cycle and Day 1 of the next cycle will be included as missed pills. For 
example, if the reported start date for Cycle 1 is 1 February and the reported start date for Cycle 2 is 3 
March, then the derived end date of Cycle 1 will be 2 March and 1-2 March will be included as 2 missed 
pills. If there are overlapping cycles in terms of dates, then the days will be included under the latest cycle 
and missed pills will be reported accordingly. For example, if the subject takes pills up to Day 24 in Cycle 
1, then starts Cycle 2 on the same date as Day 25 of Cycle 1, so Days 25 to Day 28 of Cycle 1 will not be 
included in Cycle1 and these will not be counted as missed pills for Cycle 1.  
5.7.2 Overall compliance 
In the derivation of overall compliance, all data collected on days between the date of first dose and date 
of last dose will be included in the derivation. The overall compliance will be determined by summing the 
total number of pills (active or inactive) taken across all cycles. The overall compliance will be calculated 
as 
100 𝑥 
𝑡ℎ𝑒 𝑡𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑝𝑖𝑙𝑙𝑠 𝑡𝑎𝑘𝑒𝑛 𝑎𝑐𝑟𝑜𝑠𝑠 𝑎𝑙𝑙 𝑐𝑦𝑐𝑙𝑒𝑠
𝑡ℎ𝑒 𝑑𝑎𝑡𝑒 𝑜𝑓 𝑙𝑎𝑠𝑡 𝑑𝑜𝑠𝑒−𝑡ℎ𝑒 𝑠𝑡𝑎𝑟𝑡 𝑑𝑎𝑡𝑒 𝑜𝑓 𝑐𝑦𝑐𝑙𝑒 1 + 1 𝑖𝑛 𝑑𝑎𝑦𝑠

In the above formula, the total number of pills taken during the cycles will be the sum of pills recorded 
across all days between the date of first dose of study medication and the date of last dose of study 
medication, inclusive. For example, if there is no start date reported for Cycle 1 and there are pills reported 
as taken in the diary for Cycle 1, then these pills reported in Cycle 1 will not be included in the total number 
of pills taken as the date of first dose of study medication will be the start date reported for Cycle 2. 
The total number of pills taken across all subjects will be derived by summing the number of pills taken 
across the study for all subjects in the Safety Population. 
For drug accountability, the number of active pills dispensed will be calculated by multiplying the number 
of blisters dispensed by 24. The number of inactive pills dispensed will be calculated by multiplying the 
number of blisters dispensed by 4. The number of active and inactive pills returned will be recorded on the 
CRF. 
5.8 Extent of Exposure 
The duration of total exposure to the investigational product in days will be determined from the first and 
last dosing dates during the treatment period and is derived as the last dose date – the first dose date + 1. 
The last dose date will be the date the last tablet was taken regardless of whether this is an active or inactive 
tablet. The total extent of exposure across all subjects in years will be derived by summing the total 
exposure in days across all subjects in the Safety Population and dividing it by 365.25 to convert the units 
from days to years. This will be used in the derivation of event rates for adverse events as this represents 
the duration of the on-treatment period for treatment emergent adverse events. 
The duration of actual exposure to the investigational product in days will be determined by subtracting the 
total number of days where no pills were taken from the duration of total exposure. The total number of 
days where no pills were taken is equivalent to the total number of missed pills from Section 5.7 summed 
across all cycles for that subject. Days where no pills were taken include days between Day 28 of a cycle 
and Day 1 of the next cycle where there are gaps between cycles and days within a cycle where there are 
no active or inactive pills taken. The total extent of actual exposure across all subjects in years will be 
derived by summing the exposure in days across all subjects in the Safety Population and dividing it by 
365.25 to convert the units from days to years. 
The duration of actual exposure will be used to determine whether or not a subject has had at least 26 
weeks exposure and whether or not a subject has had at least 52 weeks exposure. 
The number of cycles of treatment will be derived for each subject by determining the number of cycles as 
per the definition provided in Section 5.1.  
5.9 Pregnancy Related Definitions 
The date of conception will be estimated for each reported pregnancy by the Principal investigator. This 
estimated date of conception will be used to determine whether the pregnancy was pre-, on- or post-
treatment. In addition, the estimated date of conception will be reviewed alongside the compliance data 
recorded on the subject diary and other pertinent data collected to determine whether the pregnancy is due 
to method or user failure. The definitions of pre-, on- and post-treatment pregnancies and for method and 
user failure pregnancies are provided below. 
5.9.1 Pre-Treatment Pregnancies 
Pre-treatment pregnancies are pregnancies with an estimated date of conception before the date of the 
first dose of study medication. 
5.9.2 On-Treatment Pregnancies 
On-treatment pregnancies are pregnancies with an estimated date of conception during the On-Treatment 
Period for contraceptive efficacy (see Section 5.3 for the definition of the On-Treatment Period). In cases

where the date of conception cannot be established unequivocally (e.g. subjects is lost to follow up), this 
pregnancy will be considered as on-treatment pregnancy. 
5.9.3 Post-Treatment Pregnancies 
Post-treatment pregnancies are pregnancies with an estimated date of conception after the end of the On-
Treatment Period for contraceptive efficacy. 
5.9.4 Method and User Failure Pregnancies  
User failure pregnancies are pregnancies where the subject did not take the study medication correctly as 
per Section 9.4.4 of the Protocol during the cycle in which the estimated date of conception occurred or 
used drugs that have the potential to trigger interactions with COC (Section 9.4.6 of the Protocol). This also 
applies if the subject repeatedly missed tablets during the cycle (more than 2 consecutive active pills or 
more than 4 active pills). Pregnancies not identified as due to user failure will be considered to be method 
failure pregnancies. The pregnancy narratives are used to determine whether a pregnancy is a user or 
method failure pregnancy. 
Each on-treatment pregnancy will be reviewed in conjunction with the data collected and classified as either 
a method failure or a user failure pregnancy prior to database lock.  
5.10 Bleeding Patterns 
The subject diary data will be used to characterize bleeding patterns. Bleeding data will be analyzed by 
cycle and by RP. 
5.10.1 Definitions of Bleeding and Spotting 
Definitions for bleeding and spotting used for the cycle and RP analysis are provided in Table 1 below. In 
the diary, “0” was to be ticked for no bleeding or spotting, “1” for spotting and “2” for bleeding. 
Table 1: Bleeding and spotting definitions

5.10.2 Cycle analysis 
5.10.2.1 Definition of cycles 
In the cycle analysis of a 24/4 regimen of a COC, an up to 7-day vaginal bleeding is scheduled to occur in 
conjunction with the first inactive tablet (Day 25) and end on Day 3 of the next cycle (expected bleeding 
period). In principle, no vaginal bleeding is expected to occur at other times during the cycle. This means 
that the remainder of the cycle constituted the expected non-bleeding period of 21 days. Therefore, any 
bleeding/spotting that occurs during the expected non-bleeding period (starting on Day 4 of the actual cycle 
up to and including Day 24) are considered as unscheduled. 
The following definitions (Table 2) will be used for the cycle analysis: 
Table 2: Bleeding/spotting definitions used for the cycle analysis 
Scheduled 
Bleeding/Spotting 
(Withdrawal 
Bleeding/Spotting) 
Any bleeding/spotting that occurs during the hormone-free interval (i.e. Days 25 
– 28) and continues through Days 1-3 of the subsequent active cycle. 
Note: any bleeding/spotting that occurs while taking active hormones during 
Days 1-7 of the first cycle will be imputed as no bleeding. 
Unscheduled 
Bleeding/Spotting 
Any bleeding/spotting that occurs while taking active hormones that does not 
meet the criteria for scheduled bleeding/spotting. 
Unscheduled 
Bleeding 
Any bleeding that occurs while taking active hormones that does not meet the 
criteria for scheduled bleeding. 
Unscheduled 
Spotting 
Any spotting that occurs while taking active hormones that does not meet the 
criteria scheduled spotting. 
Early Withdrawal 
Bleeding/Spotting 
Any bleeding/spotting episode that starts before the scheduled bleeding/spotting 
period and continues into the scheduled bleeding/spotting period. 
Continued 
withdrawal 
bleeding/spotting 
Any bleeding/spotting episode that starts in the scheduled bleeding/spotting 
period and continues after the scheduled bleeding/spotting period. 
 
  
Based on these definitions, the cycle analysis of bleeding/spotting episodes will perform in two ways: 
 
a classical approach 
 
a modified cycle analysis  
5.10.2.2 Classical cycle analysis 
In the classical analysis, early and continued withdrawal bleeding are regarded as scheduled. 
The following rules will be used for the classical approach to classify each bleeding only episode, spotting 
only episode or bleeding/spotting episode as scheduled or unscheduled: 
The episode is defined as unscheduled, if any of the following criteria are met:  
 
The episode has a start date after Day 7 of Cycle 1 and an end date that is on or before Day 24 of 
Cycle 1 
 
For Cycles 2 to 13, the episode has a start date after Day 3 of the cycle and an end date that is on 
or before Day 24 of the cycle

The episode is defined as scheduled (withdrawal bleeding and/or spotting), if any of the following criteria 
are met: 
 
The episode has a start date after Day 24 of the cycle and an end date that is on or before Day 3 
of the next cycle 
 
The episode has a start date after Day 24 of the cycle and an end date that is after Day 3 of the 
next cycle (continued withdrawal bleeding/spotting).  
o 
Note it is not possible to have continued withdrawal bleeding for Cycle 13 because data 
are not collected for Cycle 14 
 
The episode has a start date before Day 24 of the cycle and an end date on or after Day 25 (early 
withdrawal bleeding/spotting). 
All bleeding days and spotting days will then be classified as scheduled or unscheduled based on whether 
the bleeding or spotting days are included in a scheduled or unscheduled episode using the rules in this 
Section above. A bleeding day or spotting day that occurs in a scheduled episode will be classified as 
scheduled and a bleeding day or spotting day that occurs in an unscheduled episode will be classified as 
unscheduled.  
5.10.2.3 Modified Cycle Analysis  
In the modified cycle analysis, the definitions of expected non-bleeding and expected bleeding periods are 
strictly followed, i.e., all bleeding episodes that overlap with expected non-bleeding intervals are considered 
unscheduled. Thus in this analysis, the definitions of scheduled and unscheduled bleeding/spotting 
episodes presented in the Table 2 are also applicable, but early and continued withdrawal bleedings are 
regarded as unscheduled. 
Therefore, in the derivation of endpoints where early and continued withdrawal bleeding are classed as 
unscheduled bleeding the following rules are used to classify each bleeding only episode, spotting only 
episode or bleeding/spotting episode as scheduled or unscheduled:  
The episode is defined as unscheduled, if any of the following criteria are met:  
 
The episode has a start date after Day 7 of Cycle 1 and an end date that is on or before Day 24 of 
Cycle 1 
 
For Cycles 2 to 13, the episode has a start date after Day 3 of the cycle and an end date that is on 
or before Day 24 of the cycle 
 
The episode has a start date after Day 24 of the cycle and an end date that is after Day 3 of the 
next cycle (continued withdrawal bleeding/spotting)  
o 
Note it is not possible to have continued withdrawal bleeding for Cycle 13 because data 
are not collected for Cycle 14 
 
The episode has a start date before Day 24 of the cycle and an end date that is on or after Day 25 
(early withdrawal bleeding/spotting) 
The episode is defined as scheduled (withdrawal bleeding and/or spotting), if the following criterion is met: 
 
The episode has a start date after Day 24 of the cycle and an end date that is on or before Day 3 
of the next cycle 
All bleeding days and spotting days will then be classified as scheduled or unscheduled based on whether 
the bleeding or spotting days are included in a scheduled or unscheduled episode in the same way as 
outlined for the classical analysis but using the rules in this Section above where early and continued 
withdrawal bleeding are classed as unscheduled episodes.

5.10.3 Reference Periods (RPs) 
No additional definitions other than those displayed in Table 1 were used for the reference period analysis.  
5.10.4 Bleeding Endpoints for the Cycle Analysis 
For the cycle analysis, the evaluable cycles will be determined as described in Section 5.1 for each subject, 
missing data rules are provided in Section 5.15.2 and definitions of terminology are provided in Section 
5.10.1 and 5.10.2.  
Depending on the approach used for the cycle analysis (the classical approach versus the modified cycle 
analysis), for each evaluable cycle for each subject, the following will be determined: 
 
Whether there was at least one unscheduled bleeding only, spotting only or bleeding/spotting 
episode within that cycle (see Section 5.10.2 for definition). It will be assumed that there is at least 
one unscheduled episode during the cycle if there is an unscheduled episode that starts in the cycle 
of interest 
 
Whether there was at least one unscheduled bleeding only episode within that cycle (see Section 
5.10.2 for definition) and no unscheduled bleeding/spotting episodes and no unscheduled spotting 
only episodes. It will be assumed that there is at least one unscheduled bleeding only episode 
during the cycle if there is an unscheduled bleeding only episode that starts in the cycle of interest 
 
Whether there was at least one unscheduled spotting only episode within that cycle (see Section 
5.10.2 for definition) and no unscheduled bleeding/spotting episodes and no unscheduled bleeding 
only episodes. It will be assumed that there is at least one unscheduled spotting only episode during 
the cycle if there is an unscheduled spotting only episode that starts in the cycle of interest 
 
Whether there is an absence of any bleeding or spotting (i.e. all days in the cycle are 
bleeding/spotting-free days)  
 
Whether there is an absence of scheduled bleeding only, spotting only and bleeding/spotting 
episodes (i.e. there is no scheduled episode with a start date during that cycle of interest)  
 
Whether there is early withdrawal bleeding or spotting in that cycle (i.e. there is either an early 
withdrawal bleeding only, spotting only or bleeding/spotting episode that starts during the cycle of 
interest) 
 
Whether there is continued withdrawal bleeding or spotting in that cycle (i.e. there is either a 
continued withdrawal bleeding only, spotting only or bleeding/spotting episode that starts during 
the cycle of interest)  
 
The total (scheduled + unscheduled) number of days with bleeding and/or spotting (i.e. the number 
of bleeding days + the number of spotting days within the bleeding only, spotting only and 
bleeding/spotting episodes that start during the cycle of interest) 
 
The total (scheduled + unscheduled) number of days with bleeding only (i.e. the number of bleeding 
days within the bleeding only and bleeding/spotting episodes that start during the cycle of interest) 
 
The total (scheduled + unscheduled) number of days with spotting only (i.e. the number of spotting 
days within the spotting only and bleeding/spotting episodes that start during the cycle of interest) 
 
The number of unscheduled days with bleeding and/or spotting (i.e. the number of bleeding days 
+ the number of spotting days within the unscheduled bleeding only, spotting only and 
bleeding/spotting episodes that start during the cycle of interest)  
 
The number of unscheduled days with bleeding only (i.e. the number of bleeding days within the 
unscheduled bleeding only and bleeding/spotting episodes that start during the cycle of interest) 
 
The number of unscheduled days with spotting only (i.e. the number of spotting days within the 
unscheduled spotting only and bleeding/spotting episodes that start during the cycle of interest)

 
The number of scheduled days with bleeding and/or spotting (i.e. the number of bleeding days + 
the number of spotting days within the scheduled bleeding only, spotting only and bleeding/spotting 
episodes that start during the cycle of interest)  
 
The number of scheduled days with bleeding only (i.e. the number of bleeding days within the 
scheduled bleeding only and bleeding/spotting episodes that start during the cycle of interest) 
 
The number of scheduled days with spotting only (i.e. the number of spotting days within the 
scheduled spotting only and bleeding/spotting episodes that start during the cycle of interest) 
5.10.5 Bleeding Endpoints for Analyses by RP 
For the analyses by RP, the evaluable RPs will be determined as described in Section 5.1.2 for each 
subject, missing data rules are provided in Section 5.15.2 and definitions of terminology are provided in 
Section 5.10.1.  
The following variables will be derived for each evaluable RP and subject: 
 
The total number of days with bleeding and/or spotting (i.e. the number of bleeding days + the 
number of spotting days within the bleeding only, spotting only and bleeding/spotting episodes 
that start during the RP of interest)  
 
The total number of days with bleeding only (i.e. the number of bleeding days within the 
bleeding only and bleeding/spotting episodes that start during the RP of interest) 
 
The total number of days with spotting only (i.e. the number of spotting days within the spotting 
only and bleeding/spotting episodes that start during the RP of interest) 
 
The number of bleeding and/or spotting episodes 
 
The mean duration of the bleeding and/or spotting episodes 
 
The number of bleeding and/or spotting free episodes  
 
The mean duration of the bleeding and/or spotting free episodes  
For the number of bleeding and/or spotting episodes in the RP, the number of episodes is defined as the 
number of bleeding only episodes + the number of spotting only episodes + the number of spotting/bleeding 
episodes with a start date during that RP. The duration of an episode is derived as the end date of the 
episode – start date of the episode + 1. The mean duration of episodes in the RP is derived from the 
duration of all episodes with a start date during that RP. The full duration of each of the episodes is used in 
the derivation of the mean duration, even if the episode continues beyond the end of the RP. 
5.11 Treatment-Emergent Adverse Event (TEAE) 
A TEAE is defined as an AE with a start date or worsening during the On-Treatment Period for safety (see 
Section 5.3 for definition of the On-Treatment Period). 
If the start date for an AE is missing and the end date is either missing or on or after the date of first dose 
of study medication, then the AE will be assumed to be treatment-emergent. However, if the start date for 
an AE is missing and the end date is recorded and is before the first dose of study medication, then the AE 
will be assumed to be non-treatment emergent. 
5.12 Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-
LES-Q-SF) 
The total score of the Q-LES-Q-SF (see Appendix 5 of the Protocol) will be derived by summing the first 14 
items to obtain the raw total score. The raw total score is then transformed into a percentage maximum 
using the following formula:

In the case of questions with missing results, if 10 or more questions are answered, then the percentage 
maximum is derived as follows: 
  
𝑃𝑒𝑟𝑐𝑒𝑛𝑡𝑎𝑔𝑒 𝑀𝑎𝑥𝑖𝑚𝑢𝑚= (𝑟𝑎𝑤 𝑡𝑜𝑡𝑎𝑙 𝑠𝑐𝑜𝑟𝑒 𝑓𝑜𝑟 𝑡ℎ𝑒 𝑞𝑢𝑒𝑠𝑡𝑖𝑜𝑛𝑠 𝑎𝑛𝑠𝑤𝑒𝑟 –  𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑞𝑢𝑒𝑠𝑡𝑖𝑜𝑛𝑠 𝑎𝑛𝑠𝑤𝑒𝑟)
(𝑡ℎ𝑒 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑞𝑢𝑒𝑠𝑡𝑖𝑜𝑛𝑠 𝑎𝑛𝑠𝑤𝑒𝑟𝑒𝑑 ×  4)
 
If fewer than 10 questions are answered, then the percentage maximum will be considered to be missing. 
The change from Baseline at the end of treatment will be calculated for each subject. 
5.13 Menstrual Distress Questionnaire  
The Menstrual Distress Questionnaire (see Appendix 6 of the Protocol) will be scored according to the 
manual (Moos, 1968). The following scales will be derived by summing the items that fall within that 
specified category: pain, water retention, autonomic reactions, negative affect, impaired concentration, 
behavior change, arousal and control. Each of these are derived at each visit for the menstrual (most recent 
flow in CRF), premenstrual (4 days before in the CRF) and intermenstrual (remainder of the cycle in the 
CRF) phases by summing the items that fall under the specified scale. The scoring key is presented in 
Table 3 below. If the subject does not answer one item on any of the scale, then the scale is calculated by 
deriving the mean score for the answered items and adding that number to the sum of the answered items 
within that scale. If 2 or more items within a scale are not answered, then the scale is missing. The change 
from Baseline at the end of treatment will be calculated for each subject.

5.14 Return to Fertility 
Each woman who discontinues the study due to a pregnancy wish will be followed-up after study treatment 
discontinuation to evaluate return of spontaneous menstruation, return of fertility, or initiation of hormonal 
contraception, whichever comes first.  
The date of the first spontaneous menstruation after study discontinuation will be recorded in the eCRF and 
follow-up will be continued. Once a pregnancy is reported or once a new contraceptive method has been 
started, the date of expected pregnancy term or of contraceptive treatment initiation will be recorded in the 
eCRF and no further follow-up contact will be done. The time from last dose of study medication to the 
return to menstruation will be calculated as the date of return of menses – the date of last dose of study 
medication. If the subject’s fertility information indicates that she had confirmation of pregnancy, then time 
from last dose of study medication to the estimated date of conception will be calculated as the estimated 
date of conception – the date of last dose of study medication. The estimated date of conception will be 
derived as the date of expected pregnancy term – 38 weeks (266 days). If the subject’s fertility information 
indicates that she received a new contraceptive method, then time from last dose of study medication to

the date of the new contraceptive method will be calculated as the date of new contraceptive method – the 
date of last dose of study medication. 
5.15 Methods for Handling Missing Data 
5.15.1 Missing Data Related to the Pearl Index and Pill Intake 
In the derivation of the Pearl Index, if the subject did not respond to the question on other contraceptive 
methods in the subject diary, it will be assumed that another contraceptive method was used. The cycle will 
be classed as a not at risk cycle and excluded from the denominator of the Pearl Index. If the subject did 
not respond to the question on sexual intercourse in the subject diary, it will be assumed that she did not 
have sexual intercourse and that cycle will be classed as a not at risk cycle and excluded from the 
denominator of the Pearl Index as appropriate. 
For compliance, if the number of active (pink) and inactive (white) pills is blank in the diary, then it will be 
assumed that no pills were taken on that day. 
If there is a partial start date for a cycle, then the start date will be imputed as the day after the date of Day 
28 of the previous cycle, providing the imputed date is consistent with the non-missing part of the date 
reported and that the duration of the cycle is consequently consistent with the expected 28 days. 
5.15.2 Missing Bleeding Data 
One or two consecutive days with missing bleeding information will be interpolated with the bleeding 
information from the previous day. For three or more consecutive days with missing bleeding information, 
missing data will be interpolated using the worst bleeding observation of the bordering days. If there are 3 
or more consecutive days with missing bleeding information at the end of the diary with no non-missing 
data reported afterwards, then the missing bleeding information will be interpolated with the bleeding 
information from the day immediately prior to the missing days. Data missing after withdrawal from the 
study will not be imputed.  
In the case of an ambiguous response for bleeding on a given day, the worst response recorded will be 
used. For example, if both bleeding and spotting are reported, then the response will be set to bleeding. If 
both bleeding and absence of vaginal bleeding or spotting are reported, then the response will be set to 
bleeding. If both spotting and absence of vaginal bleeding or spotting are reported, then the response will 
be set to spotting. If bleeding, spotting and absence of vaginal bleeding or spotting are reported, then the 
response will be set to bleeding. 
The first 7 days of Cycle 1 will be imputed with no bleeding. It will be assumed that the bleeding data for 
the 3 days after the end of Cycle 13 is the same as that of the last day of Cycle 13 where bleeding data 
were recorded.  
5.15.3 Missing or Partial Dates for Medications  
In the determination of whether a medication is taken during the On-Treatment Period, the following rules 
for missing and partial dates will be applied:  
 
If the end date is before the first dose of study medication, then the medication is a prior medication, 
regardless of whether or not the start date is missing or partially missing  
 
If the end date is on or after the date of first dose of study medication, then the following rules will 
be applied for missing or partially missing start dates: 
o 
If the start date is completely missing, then the medication will be assumed to be 
concomitant. 
o 
If only the year of the start date is recorded and the year is either before or the same year 
as the end of the safety On-Treatment Period, then the medication will be assumed to be 
concomitant.

o 
If only the year of the start date is recorded and the year is after the year of the end of the 
safety On-Treatment Period, it will be considered to be a post-study treatment medication.  
o 
If only the year and the month of the start date is recorded and the month specified is either 
before or the same month as the end of the safety On-Treatment Period, then the 
medication will be assumed to be concomitant 
o 
If only the year and the month of the start date is recorded and the month specified is after 
the month of the end of the safety On-Treatment Period, it will be considered to be a post-
study treatment medication. 
5.15.4 Missing or Partial Dates for AEs  
If the start date for an AE is missing and the end date is either missing or on or after the date of first dose 
of study medication, then the AE will be assumed to be treatment-emergent. However, if the start date for 
an AE is missing and the end date is recorded and is before the first dose of study medication, then the AE 
will be assumed to be non-treatment emergent. 
6.0 Analysis Sets 
6.1 Screened Population 
The Screened Population includes all subjects who signed an informed consent (IC) form. 
The Screened Population will be used for disposition data and data will be displayed for subjects aged 18 
to 35 years and for all subjects in separate columns. 
6.2 Enrolled Population 
The Enrolled Population includes all enrolled subjects (i.e. subjects who had a non-missing enrollment date 
on the enrollment page of the CRF). 
The Enrolled Population will be used for summaries of enrollment per country. 
6.3 Safety Population 
The Safety Population includes all enrolled subjects who receive at least one dose of study medication.  
If a subject returns all study medication that was dispensed, then the subject will not be included in the 
Safety Population. If there is at least one pill that was dispensed but was not returned, but the subject diary 
has no pills recorded as taken, then it will be assumed that the subject has not taken any study medication 
and will not be included in the Safety Population. In the case of missing diary data, it will be assumed that 
no pills were taken for the corresponding days with missing data. If there was at least one pill that was 
dispensed but was not returned and the subject has taken at least one pill according the subject diary, then 
that subject will be included in the Safety Population. 
The Safety Population will be used for compliance and exposure data with data displayed for subjects aged 
18 to 35 years and for all subjects in separate columns. The Safety Population will also be used for safety 
presented for all subjects. 
Follow-up evaluations will be presented for subjects in the Safety Population who discontinued study 
medication with pregnancy wish as the reason for discontinuation. 
6.4 Intention-to-Treat (ITT) Population 
The ITT Population includes all enrolled subjects who receive at least one dose of study medication. The 
ITT Population is the same as the Safety Population for this study. 
The ITT Population will be used for baseline and contraceptive efficacy data with data displayed for subjects 
aged 18 to 35 years and for all subjects in separate columns. The ITT Population will also be used for

protocol deviations, bleeding, endometrial substudy and quality of life data with data presented for all 
subjects.  
Endometrial biopsy data will be presented for subjects in the ITT Population who had signed the informed 
consent form for the endometrial biopsy Substudy. Only subjects who had 2 biopsies will be included in 
the summary tables for the endometrial biopsy data. Subjects who are pregnant at the time that the 
biopsies were taken will be excluded from the summary tables. 
6.5 Per-Protocol (PP) Population 
The bleeding data cycle analysis will be presented in the PP Population. For the bleeding analysis, the PP 
Population will exclude cycles based on the rules in Section 5.1.2. Subjects in the ITT Population with at 
least one evaluable cycle for the bleeding analysis will be included in the PP Population and only their 
evaluable cycles will be included in the PP analysis for bleeding data. Subjects will be excluded from the 
PP Population entirely if they have no evaluable cycles for the bleeding analysis. 
7.0 Interim Analyses 
There are no planned interim analyses for this study. 
8.0 Data Review 
8.1 Data Handling and Transfer 
Processes for data handling and transfer will be documented in the Data Management Plan. 
8.2 Data Screening 
Beyond the data screening built into the PRA Data Management Plan, the PRA programming of analysis 
datasets, tables, figures, and listings (TFL) provides additional data screening. Presumed data issues will 
be output into SAS logs identified by the word “Problem” and extracted from the logs by a SAS macro and 
sent to Data Management. 
Review of a pre-freeze TFL run on clean subjects and a post-freeze TFL run on the frozen database allow 
for further data screening prior to lock. The post-freeze TFL will be discussed with the sponsor in a data 
review meeting to identify any final data issues and seek corrections prior to database lock. The PRA 
statistician and the sponsor must approve database lock. 
8.3 Data Review Meetings 
Data review meetings will be held during the course of the study prior to database lock and the following 
may be reviewed during these meetings: 
 
Important protocol deviations and exclusion from the PP Population 
 
Classification of at risk and not at risk cycles for the Pearl Index derivation where the classification 
is not clear based on the data collected and the rules in the SAP 
 
Classification of on-, pre- and post- treatment pregnancies for the Pearl Index derivation 
 
Classification of method failure and user failure pregnancies for the method failure Pearl Index 
derivation 
 
Classification of evaluable and non-evaluable cycles for the PP bleeding analysis where the 
classification is not clear based on the data collected and the rules in the SAP

9.0 Statistical Methods 
All analyses will be conducted using SAS version 9.4 or higher. 
No formal statistical analyses will be performed in this study. 
The following conventions will be used when presenting summary statistics for study data: 
 
Continuous variables will be summarized using the following descriptive statistics: number of 
subjects (n), mean, standard deviation (SD), standard error of the mean (SEM), median, minimum 
(min), maximum (max), 25th percentile (lower quartile or Q1) and 75th percentile (upper quartile or 
Q3) 
 
Categorical and count variables will be summarized by the number of subjects (n) and the percent 
of subjects in each category. For AE tables, m may also be presented which represents the number 
of events. Percentages will be presented to 1 decimal place 
 
The number of subjects or observations will be presented as an integer 
 
Mean, median, lower quartile and upper quartile will be presented to 1 decimal place more than the 
raw value 
 
Min and max will be presented to the same number of decimal places as the raw value 
 
Standard deviation will be presented to 2 decimal places more than the raw value, up to a 
reasonable number of decimal places (i.e., rarely more than 3 decimal places unless the nature of 
the data suggests this) 
 
The denominator for percentage calculations will be the number of non-missing observations at 
that visit. Where this isn’t appropriate, the number of subjects in the relevant population will be used 
9.1 Subject Disposition 
All summaries in this Section will be presented for subjects aged 18 to 35 years and for all subjects. This 
will be based on the Screened Population. 
The number and percentage of subjects treated in the study will be presented, together with the number 
and percentage of subjects who completed the study and the number and percentage of subjects who 
withdrew from the study prematurely with a breakdown of the corresponding reasons for withdrawal. If a 
subject returns all study medication that was dispensed, then the subject will not be classed as treated. If 
there is at least one pill that was dispensed but was not returned, but the subject diary has no pills recorded 
as taken, then it will be assumed that the subject has not taken any study medication and will not be classed 
as treated. In the case of missing diary data, it will be assumed that no pills were taken for the corresponding 
days with missing data. If there was at least one pill that was dispensed but was not returned and the 
subject has taken at least one pill according the subject diary, then that subject will be classed as treated.  
Tabulations of the number and percentage of subjects included in each analysis set will be provided. The 
percentage will not be presented for the Screened and Enrolled Populations. Percentages will be derived 
based on the number of subjects enrolled. 
A tabulation of the number and percentage of subjects enrolled at each site and country will be summarized 
in the Enrolled Population. 
Disposition data and the site and country will be listed in the Enrolled Population. Information on inclusion 
in each of the analysis sets will be listed in the Screened Population. Screening failures will be listed with 
the reason for the screening failure. 
The cumulative discontinuation rate, as determined by life-table methods, together with the corresponding 
95% CIs will be presented in the ITT population for all subjects and for subject’s aged 18 to 35 years

discontinuation occurred for subjects who discontinued from the study prematurely. Subjects who did not 
discontinue from the study prematurely will be censored in Cycle 13. The rate of discontinuation and 95% 
CIs will be calculated based on Kaplan-Meier estimates for each cycle. Additionally, the estimated survival 
function against time (cycle) will be provided.  
9.2 Protocol Deviations and Violations 
The important protocol deviations for this study will be specified in the Protocol Deviation Guidance 
Template. Per PRA processes, protocol deviations will be entered into PRA’s Clinical Trials Management 
System (CTMS). The study team and the sponsor will conduct ongoing reviews of the protocol deviations 
from CTMS to identify deviations which meet the criteria for important.  
The number and percentage of subjects who had an important protocol deviation will be summarized in the 
ITT Population. 
All important protocol deviations will be listed in the ITT Population. 
The important protocol deviations will be reviewed and their potential to impact the analysis of the bleeding 
data will be assessed against the rules specified in Sections 5.1.2. If there is a potential for a specific 
important protocol deviation to impact this analysis, then the impacted cycles for that subject will be 
excluded from the PP analysis for bleeding data. Subjects with no evaluable cycles will be excluded from 
the PP Population for the analysis of bleeding data. The PP Population and the cycles to be excluded from 
the PP analysis must be finalized at the post-freeze data review meeting (or earlier), prior to database lock.

Medical history will be summarized in the ITT. Medical history will be classified into a standardized 
terminology using the Medical Dictionary for Regulatory Activities (MedDRA) system organ classifications 
and preferred terms. Version 19.0 of MedDRA will be used as coding dictionary.  
Surgical history will not be summarized. 
All medical and surgical history recorded will be listed in the ITT Population. 
9.5 Efficacy Analyses 
9.5.1 Primary Variable 
The primary variable will be summarized using the Pearl Index in the ITT population aged 18 to 35 years 
inclusive at Screening with at risk cycles. Subjects in this age group will not be censored on their 36th 
birthday for the pregnancy assessment. The Pearl Index will be presented with corresponding 95% CIs. No 
formal statistical analyses will be conducted for the primary variable. 
The Pearl Index, defined as the number of pregnancies per 100 women-years of treatment, will be 
calculated as 
Pearl Index = 
1300 x number of on −treatment pregnancies
number of women −28 day equivalent cycles of treatment 
Only at risk cycles will be included in the denominator of the Pearl Index calculation. At risk cycles will be 
defined as cycles in which the following criteria are met: 
1. No other methods of birth control (including condoms) are used by the subject as confirmed in the 
subject diary  
2. The subject confirmed that sexual intercourse occurred during the cycle in the subject diary 
Note that if conception occurs in a cycle, then that cycle will be included as an at risk cycle in the 
denominator even if other methods of birth control were used during that cycle or the subject did not confirm 
that they had had sexual intercourse. Cycles after the cycle of conception will not be included as at risk 
cycles and will be excluded from the denominator. 
The number of women-28 day equivalent cycles of treatment is the sum of the number of at risk cycles 
across all subjects. The total number of at risk cycles will be presented in the table.  
All on-treatment pregnancies will be included in the numerator for the Pearl Index (see Section 5.9.1 for 
definition of on-treatment pregnancies).  
For calculation purposes a cycle will be defined as per Section 5.1.1.  
The 95% CI for Pearl Indices will be calculated using a Poisson distribution. The confidence interval limits 
are calculated by the following equations: 
𝐶𝐼𝐿𝑂𝑊𝐸𝑅= 1300 ×

where x is the number of on-treatment pregnancies. 
The Pearl Index and corresponding 95% CIs will be presented by the subgroups described in Section 4.3 
for subjects aged 18 to 35 years. All subject diary data, pregnancy information and at risk cycles for each 
analysis will be listed.

9.5.2 Secondary Variables 
9.5.2.1 Pearl Index 
The Pearl Index and corresponding 95% CIs will be presented for all subjects in the ITT Population (see 
Section 9.5.1 for details) including only at risk cycles in the denominator. At risk cycles will be defined as 
cycles in which no other methods of birth control (including condoms) are used by the subject as confirmed 
in the subject diary, and the subject confirmed that sexual intercourse occurred during the cycle in the 
subject diary. The number of on-treatment pregnancies and at risk cycles will be presented. 
The Pearl Index and corresponding 95% CIs will be presented for subjects aged 18 to 35 years and for all 
subjects in the ITT Population including all cycles in the denominator with the exception of cycles after the 
cycle of conception in the case of pregnancy.  
The Pearl Index and corresponding 95% CIs will also be presented for subjects aged 18 to 35 years and 
for all subjects in the ITT Population employing a modified at risk definition. With this definition, at risk cycles 
will be defined as cycles in which no other methods of birth control (including condoms) are used by the 
subject while cycles with and without confirmed intercourse are being included in the denominator.  
9.5.2.2 Method Failure Pearl Index 
The method failure Pearl Index is calculated using the same method as the Pearl Index (see Section 9.5.1 
for details), but includes only those pregnancies that were classified as method failure (see Section 5.9.4 
for details). Pregnancies due to user failure will be excluded from the numerator. 
The method failure Pearl Index and corresponding 95% CIs will be presented for subjects aged 18 to 35 
years at Screening in the ITT Population and for all subjects in the ITT Population including only at risk 
cycles in the denominator. The number of on-treatment pregnancies and at risk cycles will be presented. 
This will be derived in 4 ways: 
 
Including all at risk cycles in the denominator where at risk cycles will be defined as cycles in which 
no other methods of birth control (including condoms) are used by the subject as confirmed in the 
subject diary and the subject confirmed that sexual intercourse occurred during the cycle in the 
subject diary. 
 
Including all at risk cycles in the denominator employing a modified at risk definition. With this 
definition, at risk cycles will be defined as cycles in which no other methods of birth control 
(including condoms) are used by the subject while cycles with and without confirmed intercourse 
are being included in the denominator.  
 
Including only at risk cycles in the denominator where at risk cycles will be defined as cycles in 
which no other methods of birth control (including condoms) are used by the subject as confirmed 
in the subject diary and the subject confirmed that sexual intercourse occurred during the cycle in 
the subject diary where the subject was compliant with the dosing rules 3 to 8 in Section 5.1.1.  
 
Including only modified at risk cycles in the denominator where at risk cycles will be defined as 
cycles in which no other methods of birth control (including condoms) are used by the subject as 
confirmed in the subject diary where the subject was compliant with the dosing rules 3 to 8 in 
Section 5.1.1 while cycles with and without confirmed intercourse are being included in the 
denominator.  
9.5.2.3 Life-Table Rates 
In addition, the cumulative pregnancy rate, as determined by life-table methods, together with the 
corresponding 95% CIs will be presented for all pregnancies and for all method failure pregnancies in the 
ITT population for all subjects and for subject’s aged 18 to 35 years inclusive at Screening.

Life-table analyses will provide one-year life-table pregnancy rates for each efficacy endpoint (i.e. for all 
pregnancies as used in the Pearl Index and for all method failure pregnancies as used in the method failure 
Pearl Index). The life-table analysis will evaluate the cumulative probability of pregnancy by cycle using 
PROC LIFETEST in SAS where the time variable is the cycle where the estimated conception occurred for 
subjects who had an on-treatment event of pregnancy. Subjects who did not have an on-treatment event 
of pregnancy will be censored on the cycle prior to the cycle in which they discontinued from the study. The 
rate of pregnancy and 95% CIs will be calculated based on Kaplan-Meier estimates for each cycle. 
Additionally, the estimated survival function against time (cycle) will be provided. 
9.5.3 Bleeding and Spotting 
Bleeding patterns will be analyzed using data from the subject diary. A cycle analysis and an analysis by 
RP will be performed (see Section 5.1.2 for details). Derived data for bleeding and spotting will be listed in 
the ITT Population.  
9.5.3.1 Cycle Analysis  
The cycle analysis will be performed following two approaches: a classical (for details see Section 5.10.2.2) 
and a modified cycle analysis (for details see Section 5.10.2.3).  
The classical analysis will be performed in the ITT and PP Population. This analysis will also be repeated 
for the following populations: 
 
The PP analysis excluding cycles where there is at least 1 day where an active pill was missed 
 
The ITT analysis including only cycles where 1 active pill was missed 
 
The ITT analysis including only cycles where 2 or more active pills were missed.  
The number of subjects with evaluable cycles for each population will be summarized by cycle.  
The modified cycle analysis where early and continued withdrawal bleeding are classed as unscheduled 
bleeding will be performed in the ITT Population, PP Population and the PP Population excluding cycles 
where there is at least 1 day where an active pill was missed.  
Details of the exclusion of cycles from the PP Population are provided in Section 5.1.2. Vaginal bleeding 
will be classified as spotting or bleeding and scheduled or unscheduled based on the definitions in Section 
5.10.1 and 5.10.2. Rules for handling missing data are provided in Section 5.15.2. The inclusion of cycles 
in ITT Population, PP Population and PP Population excluding cycles with at least 1 active pill missed in 
the cycle will be listed by subject and cycle along with reasons for exclusion of the cycle from the PP 
Population analysis and the number of missed pills. 
The following information will be summarized for bleeding and spotting for the cycle analysis: 
 
Number and percentage of subjects with unscheduled bleeding and/or spotting episodes for each 
cycle (classical analysis + modified cycle analysis) 
 
Number and percentage of subjects with unscheduled bleeding only episodes for each cycle 
(classical analysis + modified cycle analysis)  
 
Number and percentage of subjects with unscheduled spotting only episodes for each cycle 
(classical analysis + modified cycle analysis)

bleeding and/or spotting days, bleeding days, and spotting days within a cycle will also be summarized in 
subjects who experienced an unscheduled bleeding and/or spotting episode within that cycle. This will be 
presented for the classical and modified analysis in the ITT and PP Populations. Additionally, unscheduled 
bleeding and spotting and the absence of scheduled bleeding will be summarized for all subgroups 
specified in Section 4.3 by cycle for the classic cycle analysis for the ITT, PP Population and the PP

9.6 Safety Analyses 
9.6.1 Adverse Events 
TEAEs will be classified into a standardized terminology using the MedDRA system organ classifications 
and preferred terms. Version 19.0 of MedDRA will be used as coding dictionary. The incidence of TEAEs 
will be summarized for the Safety Population. 
A summary of TEAEs including the number of events reported, the annual rate and the number and 
percentage of subjects reporting the following will be presented: 
 
Any TEAE 
 
Any TEAE leading to death 
 
Any treatment-emergent SAE 
 
Any TEAE leading to premature discontinuation from the study 
 
Any SAE related to study medication 
TEAEs are defined in Section 5.11. The annual rate will be derived as the number of events divided by the 
total exposure across all subjects in years. 
A breakdown of the number and percentage of subjects reporting each TEAE with the corresponding 
number of events, categorized by body system and preferred term coded according to the MedDRA 
dictionary, will be presented. Note that subjects are only counted once within each body system or preferred 
term but subjects with multiple events of a specific type will be counted once for each occurrence in the 
number of events column. 
A further tabulation of these data, categorized by relationship to study drug, will be presented. Subjects 
with multiple events within a particular body system or preferred term will be counted under the category of 
their most drug-related event within that body system or preferred term in column for the number of subjects. 
In the column for the number of events, multiple events of a specific type and relationship will be counted 
once for each occurrence. Relationship to study drug is categorized as not related (not related and unlikely 
on the CRF) and related (possible, probable and highly probable on the CRF). This will be repeated for 
TEAEs leading to premature discontinuation from the study. 
TEAEs will also be presented by severity. For each system organ class and preferred term, subjects are 
included only once, at the maximum severity. In the column for the number of events, multiple events of a 
specific type and severity will be counted once for each occurrence.  
All adverse events (including non-treatment-emergent events) recorded on the CRF will be listed. The 
following listings will be generated in the Screened Population: 
 
All AEs 
 
AEs leading to premature discontinuation from the study

For continuous clinical laboratory analytes, the absolute value and change from baseline will be 
summarized by analyte and visit using descriptive statistics for the Safety Population.  
Shifts to values outside of the normal range will be presented by analyte and visit and will be summarized 
by the number and percentage of subjects with evaluable shifts. The denominators for calculating the 
percentages will be the number of subjects in the Safety Population with both the Baseline value and the 
value at the specified visit recorded. 
If the value is below the lower limit of quantification, then half the lower limit of quantification will be used in 
the summary tables to calculate the descriptive statistics. If the value is above the upper limit of 
quantification, then the upper limit of quantification will be used in the summary tables to calculate the 
descriptive statistics. In the listings, values will be listed as collected without the imputation applied.  
All clinical laboratory values, abnormal clinical laboratory values, and clinical significant laboratory values 
will also be provided in data listings in the Safety Population including data collected at any unscheduled

Substudy and who had 2 biopsies (one at Screening and one at Visit 7a) will be included in the summary 
tables for the endometrial biopsy data. Subjects who are pregnant at the time that the biopsies were taken 
will be excluded from the summary tables. The number and percentage of subjects in each histological 
category will be presented at the Screening Visit (Visit 1) and at Visit 7a for subjects who have completed 
at least 10 cycles. In addition, a shift table will be presented from the Screening Visit to Visit 7a with the 
number of subjects with evaluable histological data at Screening Visit and at Visit 7a the denominator. 
All endometrial biopsy data will be listed. 
10.0 Validation 
PRA's goal is to ensure that each TFL delivery is submitted to the highest level of quality. PRA’s quality 
control procedures will be documented separately in the study specific Quality Control Plan.

12.0 Amendment to the Statistical Analysis Plan 
12.1 Amendment 1 from SAP dated 15 July 2016 
The key changes to the SAP in amendment 1 are as follows: 
 
Missing data rules moved to one section for missing data 
 
The addition of analyses for the Pearl Index to look at the rate of on-treatment pregnancies and 
on-treatment method failure pregnancies where the at risk cycles are defined as cycles in which 
no other methods of birth control are used by the subject 
 
The addition of an analysis for the Pearl Index to look at the rate of method failure on-treatment 
pregnancies excluding at risk cycles that were not compliant according to Section 9.4.4 of the 
protocol 
 
Clarification of the definition of the evaluable cycles for the bleeding analysis in the PP Population 
in cases where the post Screening biopsy was not performed during Cycle 13 
 
Addition of criteria for exclusion from the PP Population to exclude cycles within 28 days after 
prohibited mediations 
 
Clarification that the Baseline value for the Menstrual Distress Questionnaire is the value 
collected at Visit 3 as the date of collection is not collected 
 
Clarification added that compliance by cycle will be based on the cycles defined from the start 
dates of the cycles per Section 5.1 including detail on how gaps between cycles and overlapping 
cycles are handled 
 
Clarification added that for overall compliance only pills reported between the start and stop date 
for study medication will be included in the numerator 
 
The addition of actual exposure accounting for days where no pills were taken

 
Addition of the number of subjects with bleeding only episodes and spotting only episodes by 
cycle as endpoints 
 
Change in the definitions of unscheduled and scheduled bleeding and spotting days to use the 
episodes  
 
Clarification added for imputation for missing bleeding data to cover scenarios where 3 or more 
days having missing data at the end of the diary data collected 
 
The definition of an evaluable reference period was updated to exclude reference periods where 
there are gaps between the cycles 
 
Cumulative amenorrhea rate added as an endpoint 
 
Bleeding analysis section restructured and split out into the classical cycle analysis (including 
early and continued withdrawal bleeding as scheduled) which is now classed as the primary 
definition and the modified analysis (including early and continued withdrawal bleeding as 
unscheduled) which is no longer classed as the primary definition 
 
Analyses of bleeding data added for cycles with exactly 1 missed active pill and for cycles with at 
least 2 missed active pills  
 
The bleeding analysis by reference period was simplified to no longer differentiate between 
scheduled and unscheduled bleeding 
 
Clarification on the scales derived for the Menstrual Distress Questionnaire added 
 
Enrolled Population definition corrected to use the enrollment date  
 
PP Population corrected to make it clear that only the PP Population for bleeding is being derived 
 
Reference to ATC classification removed as data are not coded to ATC in this study 
 
Clarification added to indicate that BMI will be programmatically derived from height and weight 
for the vital signs and demography tables 
 
Listing added for the at risk cycles for each Pearl Index analysis 
 
Clarification added to categorize relationship to study medication as not related and related for 
AEs 
 
Change to the handling of unscheduled laboratory assessments and clarification added for values 
above the upper limit of quantification and values below the lower limit of quantification 
 
Choriogonadotropin beta and eGFR added as laboratory parameters to be summarized 
 
Addition of summaries and listings of evaluable cycles and reference periods for the bleeding 
analysis 
 
Clarification added that subjects who are pregnant at the time that the endometrial biopsies were 
performed will be excluded from summary tables for endometrial biopsies and the analysis set for 
endometrial biopsy data changed from the Safety Population to the Full Analysis Set 
 
Bleeding and spotting analysis section moved to Section 9.5 
 
12.2 Amendment 2 from Amendment 1 dated 19 April 2018 
The key changes to the SAP in amendment 2 are as follows: 
 
Correction to the definition of the alternative definition of at risk cycles that will be used for the 
derivation of the Pearl Index for method failure pregnancies based on compliance to indicate that 
all 8 criteria need to be met for a cycle to be at risk 
 
Correction to definition of the presence of a bleeding only unscheduled episode and the presence 
of a spotting only unscheduled episode for the cycle analysis for bleeding 
 
Addition of a section for missing or partial dates for AEs 
 
Addition of a new analysis of the method failure Pearl Index icluding only modified at risk cycles in 
the denominator where at risk cycles will be defined as cycles in which no other methods of birth 
control (including condoms) are used by the subject as confirmed in the subject diary where the 
subject was compliant with the dosing rules 3 to 8 in Section 5.1.1 while cycles with and without 
confirmed intercourse are being included in the denominator

 
Clarification added on how to handle pregnancies for the at risk cycles when the cycle is not in the 
diary data 
 
Clarification added on the handling of partial dates in the diary data 
 
Addition of summary tables of unscheduled bleeding and spotting days in subjects who had 
unscheduled bleeding and/or spotting episodes 
 
Clarification added that the exclusion of cycles for unauthorized medications may be different 
between the bleeding analysis and contraceptive efficacy
