PROTOCOL SYNOPSIS 
Test Drugs: 
Proellex® (Telapristone Acetate): 12 mg gelatin capsules 
Protocol Number: 
ZPU-203EXT  
Study Purpose: 
To determine the safety of extended treatment with Proellex in 
women who have successfully completed either study ZPV-201 or 
ZPU-203 and meet eligibility criteria. 
Study Design and 
Duration 
Of Treatment: 
This study is an open-label, multi-center extension study to evaluate 
the safety of continued treatment with Proellex in subjects who 
successfully completed either study ZPV-201 or ZPU-203.   The 
study requires 16 visits and is approximately 13 months in duration 
(up to 15 months for selected sites).   Subjects will be treated orally 
with 12 mg Proellex/day for three 18-week courses, each separated 
by an ODI.  Throughout the study women will record study 
information in the diary, PBAC, and questionnaires as outlined in the 
study procedures. 
The start of the first 18-week course of treatment (Course 1) should 
commence no later than 4 days after the end of bleeding, i.e. at visit 
24 (or Visit 19, see Study Procedures below) of the previous study.  
Once dosing for Course 1 is stopped, subjects will be followed until 
menses returns.  The start of the second and third 18 week courses of 
treatment (Courses 2 and 3) will commence no later than 4 days after 
the end of bleeding in the subject’s menses following withdrawal of 
drug after the previous course has been completed.   
At selected sites subjects will commence dosing on the first day of 
bleeding in their next menstrual cycle after Visit 19 or Visit 24 (about 
3 weeks after V19 or 24).  The start of the second and third courses of 
treatment will start on the first day of bleeding in the subject’s second 
menses following withdrawal of study drug. 
During the ODI, subjects will continue to record study information in 
the daily paper diary and PBAC charts. 
Any subject who has any 28-day period during treatment (not 
including the ODIs) without a bleeding score >1 will be deemed to 
have achieved amenorrhea.  Subjects who do not achieve amenorrhea 
after 8 weeks of treatment will exit the study.  After completion of 3 
courses of treatment, subjects will be followed through the 
subsequent menstrual event (recovery menses). 
A DSMB will review any liver safety events (LFTs ≥3 x ULN or 
bilirubin ≥2 x ULN). 
Subject Population: 
The study will enroll women who have successfully completed either 
study ZPV-201 or ZPU-203 and meet eligibility criteria. 
Number of Subjects: 
Up to about 60 subjects 
Number of Sites 
Approximately 10 sites  
Study Duration:  
Total participation in the study is approximately 13 months.

Statistical Methods: 
Summaries for quantitative variables include the sample size, mean, 
median, standard deviation, minimum, and maximum.  Summaries 
for categorical variables include the number and percent of patients 
for each outcome.    
Continuous efficacy endpoints, such as the change from baseline in 
uterine tumor volumes  will assess treatment effect using a within-
group t-test or appropriate non-parametric technique. The percentage 
of subjects becoming amenorrheic will be determined.

BACKGROUND INFORMATION 
6.1 
Rationale for Current Study 
Repros believes telapristone offers the potential to provide significant 
symptomatic relief to women that suffer from a variety of reproductive 
disorders in which progesterone may be implicated. 
 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
  
 
 
  
 
 
 
 
 
Based on findings from the recently completed ZP-204 low dose study of oral 
Proellex, doses from 1 mg up to 12 mg daily were administered for 
10 consecutive weeks with no observed elevations of liver enzymes or even 
trends towards increasing liver enzymes with increasing dose.  At the same 
time induction of amenorrhea was seen in a consistent fashion starting at a 3 
mg daily dose as long as trough levels of the drug were observed.  The

sponsor believes there is a direct correlation of symptomatic relief for uterine 
fibroids and endometriosis with induction of amenorrhea. 
 
 
 
 
 
  Typically women are 
dosed for 4 months (120 days) after which time the drug is withdrawn to allow 
for menses to return.  Once menses has occurred women may resume 
treatment for another dosing period. In this fashion the drug can be used to 
control the symptoms of endometriosis and fibroids until the onset of 
menopause.

Clinical Data/Human Experience 
In addition to the preclinical studies, a Phase I/II study of orally administered 
Proellex in pre-menopausal women with symptomatic leiomyomata had been 
completed.  The objectives of this study were to test the safety, efficacy, and 
pharmacokinetics of three doses of Proellex (12.5 mg, 25 mg, and 50 mg) 
administered as a once daily dose for 90 days, with study visits at one-month 
intervals.  The safety and effectiveness of Proellex was compared to placebo 
and the active control leuprolide acetate for depot suspension (Lupron Depot).  
At the conclusion of this study, exploratory analyses showed statistically 
significant efficacy differences between treatment groups (overall and pair-
wise).

TRIAL OBJECTIVES AND PURPOSE 
The primary objective of this study is to determine the safety of orally administered 
Proellex administered at 12 mg/day for up to 3 courses of treatment (18 weeks each), 
each separated by an Off-Drug Interval (ODI), to women who have completed either 
ZPV-201 or ZPU-203.   
To further investigate the effect of the timing of start of dosing upon the onset of 
amenorrhea, at selected sites the start of dosing in each cycle will be on the first day 
of bleeding rather than 0-4 days after stopping bleeding.

8.2 
Study Design 
8.2.1 Overview of Study Design 
This study is an open-label, multi-center extension study to evaluate 
the safety of continued treatment with Proellex in subjects who 
successfully completed either study ZPV-201 or ZPU-203.  The study 
requires 16 visits and is approximately 13 months in duration.   
Subjects will be treated orally with 12 mg Proellex/day for three 18-
week courses, each separated by an ODI.  Subjects will use only 
sanitary supplies provided by the sponsor.  Throughout the study 
women will record study information in the diaries and questionnaires 
as outlined in the study procedures. 
Any subject who has any 28-day period during treatment (not 
including the ODIs) without a bleeding score >1 will be deemed to 
have achieved amenorrhea (in both the current or the previous study).  
Visit 1 of this study will also be Visit 24 of the previous study unless 
18DEC2018 Abbreviated CSR ZPU-203EXT

the subject failed to achieve amenorrhea in the previous study.  Such 
subjects may enroll at Visit 19 (after first recovery menses) in the 
previous study.  Subjects who do not achieve amenorrhea after 8 
weeks of treatment in this study will exit the study. 
The start of the first 18-week course of treatment (Course 1) should 
commence no later than 4 days after the end of bleeding in the last 
menses, which should coincide with Visit 19 or 24 of the previous 
study.  Once dosing for Course 1 is stopped, subjects will be followed 
until menses returns.  The start of the second and third 18 week 
courses of treatment (Courses 2 and 3) will commence no later than 4 
days after the end of bleeding following withdrawal of drug after the 
previous course has been completed.   
At selected sites subjects will commence dosing on the first day of 
bleeding in their next menstrual cycle after Visit 19 or Visit 24 (about 
3 weeks after V19 or 24).  The start of the second and third courses of 
treatment will start on the first day of bleeding in the subject’s second 
menses following withdrawal of drug. 
During the ODI, subjects will continue to record study information in 
the daily paper diary. 
After completion of 3 courses of treatment, subjects will be followed 
through the subsequent menstrual event (recovery menses). 
A DSMB will review any liver safety events (LFTs ≥3 x ULN or bilirubin 
≥2 x ULN) . 
8.2.2 Study Drug Accountability 
The designee assigned by the Principal Investigator at each site will 
maintain accurate records of receipt of all study drugs, including dates 
of receipt.  Reasons for deviation from the expected dispensing 
regimen must also be recorded.  A Drug Dispensing Form will be 
provided for this purpose.  To satisfy regulatory requirements 
regarding drug accountability and destruction, the Principal 
Investigator at each site will return all used, unused, empty, and 
partially used study medication with dispensing records to the Sponsor 
for final accountability and disposal, after accountability has been 
verified by the study monitor.  
8.2.3 Randomization and Blinding 
As the study is open-label there will be no randomization or blinding. 
8.2.4 Study Medication 
All study drugs will be supplied by Repros Therapeutics Inc. Test 
drug, Proellex will be supplied in 40 count bottles and will be 
packaged by a clinical supplies contract vendor designated by Repros 
Therapeutics Inc.

ASSESSMENT OF SAFETY 
 
 
10.1 
Adverse Events 
10.1.1 Reporting Adverse Experiences 
Any AE (clinical sign, symptom, or disease) temporally associated 
with the use of this investigational drug, whether or not considered 
related to the investigational product, shall be documented on the CRF 
and eDC.  All SAEs and AEs reported by the subject or observed by 
the Principal Investigator for up to 30 days after the last dose of study 
medication will be individually listed.  The signs and symptoms, time 
of onset (24-hour clock), duration, action taken and follow-up 
procedures will be reported.   
10.1.2 Definitions 
Adverse Event – Any untoward medical occurrence in a clinical 
investigation subject administered a drug and does not necessarily 
have a causal relationship with this treatment.  An AE can therefore, 
be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with 
the use of an investigational product, whether or not related to the 
investigational product. 
Serious Adverse Event (SAE) – An adverse drug experience that 
results in any of the following outcomes:  death, a life-threatening 
experience, requires or prolongs subject hospitalization, results in 
persistent or significant disability/incapacity, or is a congenital 
anomaly or birth defect.   
Cases of liver transaminases that increase above 3 times the upper 
limit of normal must be reported as SAEs regardless of whether the 
above defined SAE criteria are met. 
Unexpected Adverse Event: Any adverse event that is not identified in 
nature, severity, or frequency in the current Investigator’s Brochure. 
Additionally, the Principal Investigator will evaluate all AEs as 
follows: 
Action taken:  whether or not the AE caused the subject/patient to 
discontinue the study medication.

Intensity, to be graded as: 
DEGREE 
DESCRIPTION 
Mild 
Awareness of signs and symptoms; easily tolerated 
Moderate 
Discomfort sufficient to interfere, but not prevent 
daily activity 
Severe 
Unable to carry out usual activity 
 
Relationship to study medication, to be graded as: 
DEGREE 
DESCRIPTION 
Definitely 
There is evidence of exposure to the study drug, 
for example, reliable history or acceptable 
compliance assessment; the temporal sequence of 
the AE onset relative to the medication is 
reasonable; the AE is most likely to be explained 
by the treatment than by another cause; the AE 
shows a pattern consistent with previous 
knowledge of the treatment. 
Probably 
There is evidence of exposure to the study drug; 
the temporal sequence of the AE onset relative to 
medication administration is reasonable; the AE is 
more likely explained by the treatment than by 
another cause. 
Possibly 
There is evidence of exposure to the study drug; 
the temporal sequence of the AE relative to the 
medication administration is reasonable; the AE 
could have been due to another equally likely 
cause. 
Probably 
not 
There is evidence of exposure to the study drug; 
there is another more likely cause of the AE. 
Definitely 
not 
The subject/patient did not receive the study drug; 
or temporal sequence of the AE onset relative to 
administration of the study drug is not reasonable; 
or there is another obvious cause of the AE. 
10.1.3 Serious Adverse Events (SAEs) 
The Principal Investigator shall document all SAEs in a subject 
receiving study drug until completion of the study and must be 
reported to the Repros Therapeutics Inc. Safety Monitor within 24 
hours by Fax or telephone, even if the SAE does not appear to be drug-
related.  This report should include all available information at the 
time of notification.  This notification should be followed with 
submitting a SAE Report Form provided by Repros Therapeutics Inc, 
and notifying the IRB.

STATISTICAL METHODS 
12.1 
Determination of Sample Size 
This is a extension study and the number of subjects will be dependent on the 
number of subjects completing the parent studies.  No more than 60 subjects 
are expected to enroll.  
12.2 
Statistical and Analytical Plan 
Analyses in this study will focus on comparison to two baseline assessments.  
One baseline is associated with the original parent study baseline and the other 
is associated with the 28-day period prior to the start of this extension study.  
Reference to baseline in this section refers to each baseline definition. 
12.2.1 Demographics and Subject Characteristics 
For all subjects included in this study, subject disposition and 
demographic data will be summarized.  Summaries for quantitative 
variables include the sample size, mean, median, standard deviation, 
minimum, and maximum.  Summaries for categorical variables include 
the number and percent of patients for each outcome.   
12.2.2 Incidence of Amenorrhea 
The percentage of subjects who become amenorrheic during the 28 
days leading up to the last day of dosing in each course will be 
determined.  The incidence of amenorrhea during the entire course and 
after the 11th day of the course will also be investigated. 
A subject is deemed amenorrheic if they have no bleeding intensity 
score greater than 1 using the Daily Diary Card in Appendix 2 
(spotting not requiring hygiene products) during the period.   
12.2.3 Percentage Change in PBAC Scores 
The percentage change in PBAC scores over each 28 day period of the 
course will be recorded and compared to baseline to determine onset 
of benefit. Additionally PBAC scores will be used to monitor the level 
of vaginal bleeding during the ODI. 
Within treatment group paired t-tests will evaluate treatment effect.  
While the primary assessment will be after each 18 week treatment 
course, summaries will be prepared for each of the other visits.  If data 
are missing, a last observation carried forward procedure will be used, 
including the baseline, if necessary. Non-parametric methods will be 
employed as appropriate.   
12.2.4 Percentage Change in Total and Individual Symptom Severity Scores 
for the UFSQOL 
The UFSQOL  has been validated as a three month look back

questionnaire.  The survey will be administered at baseline and at the 
end of each course.  Within group paired tests will be used to assess 
treatment effect.  Non-parametric methods will be employed as 
appropriate.  If data are missing, a last observation carried forward 
procedure will be used, including the baseline, if necessary. 
12.2.5 Percentage Change in Uterine Fibroid Volume by MRI 
The percent change from baseline in total uterine fibroid volume will 
be determined at the end of treatment.  This study will assess up to 3 
fibroids present at baseline in each subject.  The volume of these 3 
fibroids will be summed to determine the total uterine fibroid volume 
at each assessment.   
Within group paired tests will be used to assess treatment effect.  Non-
parametric methods will be employed as appropriate.  If data are 
missing, a last observation carried forward procedure will be used, 
including the baseline, if necessary. 
 
 
 
 
 
 
   
 
  
 
 
 
 
 
 
 
  
 
 
 
    
12.3 
General Statistical Issues 
A Statistical Analysis Plan (SAP) will be finalized prior to unblinding the 
study. For the efficacy variables a last observation forward approach will be 
used to impute missing data to generate a complete ITT data.  If there are no 
post-baseline efficacy data then a value of no change will be imputed for the
