1. SYNOPSIS
Title of Study 
An Open-label, Single Arm, Multicenter Study on the Efficacy, Safety, and 
Pharmacokinetics of Leuprolide Acetate 45 mg for Injectable Suspension 
Controlled Release in Subjects with Central (Gonadotropin-Dependent) 
Precocious Puberty 
Clinical Study Type 
Adaptive Design Interventional (Efficacy, Safety and Pharmacokinetics) 
Clinical Study Phase Phase III (Pivotal) 
Study Period 
Total study enrollment is expected to take approximately 12 months for 
Part A and approximately 10 months for Part B. 
Part A: Approximately 24 months for first subject first visit (FSFV) to last 
subject last visit (LSLV) 
Part B (Extension): Continuation into Part B will be dependent on results 
from Part A. If this extension is invoked, the study will be extended for 
2 more injections; therefore, FSFV to LSLV (altogether for both Parts A 
and B) will be approximately 34 months.  
Duration of 
Participation 
Screening Period: Up to 28 days 
Treatment Period, Part A: 1st and 2nd injections separated by approximately 
6 months (24 weeks); subject participation is approximately 12 months  
Treatment Period if Part B is conducted: additional 3rd and 4th injections 
separated by approximately 5 months; subject participation is a total of 
approximately 21 months from first dose in Part A 
Investigational 
Product (Study 
Drug) 
Leuprolide acetate 45 mg for injectable suspension, controlled release for 
subcutaneous injection (ELIGARD® 45 mg, TOLMAR Inc.) 
Objectives 
Primary: 
•
Determine the effectiveness of leuprolide acetate 45 mg for injectable
suspension for treatment of children with Central Precocious Puberty
(CPP).
Secondary: 
•
Evaluate the safety and tolerability of leuprolide acetate 45 mg for
injectable suspension in children with CPP.
•
Characterize the burst kinetics of leuprolide acetate 45 mg after the first
administration.
•
Characterize the pharmacodynamic (PD) relationship of leuprolide
serum concentrations to concentrations of serum luteinizing hormone
(LH), follicle stimulating hormone (FSH) and to testosterone/estradiol.
•
Assess percent changes in height velocity and bone age progression
after the first administration.
•
Assess changes in physical signs of puberty as measured by changes in
Tanner stages or in changes or onset of menses.
•
Determine the dosing interval (5 or 6 months) at which leuprolide
acetate is able to suppress LH concentration to <4 mIU/mL (after

gonadotropin releasing hormone agonist [GnRHa] stimulation test), as 
data permit. 
Study Design 
This will be an adaptive design study conducted in two parts as illustrated 
below. 
Subjects will only receive Injections #3 and #4 if Part B is conducted, based on Part A interim data. 
Part A: This will be a multicenter, open-label, single-arm 12-month study. 
Pediatric subjects who have been diagnosed with CPP but have not yet 
received GnRH agonist therapy (drug-naïve) will be eligible (see 
Inclusion/Exclusion Criteria). All subjects will have a GnRHa stimulation 
test to confirm a diagnosis of CPP.  
Pediatric subjects will receive their first study drug injection at their 
baseline visit on Day 0 and the second injection at the Month 6 visit with 
periodic evaluations and monitoring for up to a total of 12 months following 
the first injection. Subjects will return to the clinic as indicated in the 
Schedule of Assessments (SoA) periodically for 12 months from start of 
dosing for efficacy, safety and pharmacokinetic (PK) assessments.  
All subjects will participate in Part A to evaluate the efficacy of leuprolide 
acetate injection suspension 45 mg (study drug) in suppressing LH after a 
GnRHa stimulation test. An independent Data Safety Monitoring Board 
(DSMB) will review the safety of the drug throughout the study.  
An interim analysis of LH suppression from the GnRHa stimulation test 
results will be conducted after approximately 40% of the 40 subjects 
anticipated to complete 6 months of assessments have data through the 
Month 6 visit (N = approximately 16). Based on this analysis, if LH 
concentrations, after the GnRHa stimulation test, are suppressed to 
< 4 mIU/mL in < 85% of these subjects, then Part B of the study will be 
invoked. All subjects still undergoing therapy in the Part A of the study and 
those yet to enroll in the study, if eligible, will be asked to participate in the 
Part B extension study for additional dosing at shorter intervals. The 
progression to Part B extension will be based on evaluations by the DSMB 
and Sponsor. 
Part B Extension: This will be a multi-center, open-label, single-arm 
extension following Part A. Because the interim analysis will only provide 
data from a very small sample size informing the decision to conduct Part B 
of the study with a 5-month dosing interval, ALL new subjects being 
enrolled into the study will begin with Part A of the study with the first 
6-month dosing interval before proceeding to Part B. In this manner, there
will be adequate data for comparison of dosing intervals for assessment of
optimal efficacy. Only subjects who have received Injection #2 of study
drug in Part A will be permitted to enter Part B. Injections #3 and #4 will be

administered in 5-month intervals after Injection #2. Subjects will return to 
the clinic periodically up to an additional 10 months from start of Part B for 
efficacy and safety assessments. 
Number of Study 
Sites 
Multicenter: approximately 20 sites in the United States, Mexico, 
Argentina, Canada, South Korea, Australia, and New Zealand. Clinical sites 
in other countries may be added as necessary.  
Number of Subjects 
Part A: Approximately 60 subjects will be screened and/or enrolled in 
order to have approximately 40 evaluable subjects that complete 6 months 
of the study.

Page 8 of 60 
Pharmacokinetic 
Parameters 
Blood samples will be collected during the study for analysis of serum 
leuprolide concentrations. Blood samples will be assayed and used to 
characterize initial burst phase and baseline or trough concentrations of 
leuprolide acetate following administration of the first dose of the study drug 
and the relationship of leuprolide to changes in serum concentrations of LH, 
FSH, and testosterone/estradiol.  
Statistical Methods 
Data Sets to be Analyzed: 
Safety population: All subjects providing consent/assent and who received 
at least one dose of the study drug.  
Intent-to-Treat (ITT) population: Subjects providing consent/assent who 
received at least one dose of the study drug, fulfilled the protocol eligibility 
criteria, and provided at least one PD laboratory assessment post dosing.  
Per Protocol (PP) population: Subjects who have received at least one dose 
of the study drug and have fulfilled the protocol in terms of eligibility, 
interventions and outcome assessments for at least 6 months.  
Efficacy: 
Primary Efficacy Endpoint 
•
Part A: the percentage of subjects with serum LH concentrations
< 4 mIU/mL 30 minutes following an abbreviated GnRHa stimulation
test at the Month 6 visit
•
Part B: the percentage of subjects with serum LH concentrations
< 4 mIU/mL 30 minutes following an abbreviated GnRHa stimulation
test at the Month 21 visit (5 months after the Injection #4 of leuprolide
acetate)
Secondary Efficacy Endpoint: Parts A & B 
•
The percentage of subjects with suppressed serum LH concentrations
(< 4 mIU/mL) 30 minutes post GnRHa stimulation test at all assessed
timepoints
•
Changes in height velocity (growth rate) and bone age advancement will
be evaluated relative to chronological age from baseline to end of study
•
Change in physical signs of puberty as measure by changes in Tanner
stages from baseline to end of study
Exploratory Endpoints: Parts A & B 
•
Bone age progression will be further evaluated using descriptive
statistics and figures at all assessed timepoints. Changes in bone age
progression will be described for each individual and for the ITT and PP
population over the entire treatment period
•
Descriptive statistics will be used to describe changes in physical signs
of puberty as measured by changes in Tanner stages at each assessed
timepoint. Changes in Tanner staging will be described for each
individual and for the ITT and PP population over the entire treatment
period
•
The percentage of subjects with LH (< 4 mIU/mL), FSH
(< 2.5 mIU/mL), estradiol (< 20 pg/mL) or testosterone (< 30 ng/dL)

suppression to prepubertal levels and serum leuprolide levels at all 
assessed timepoints 
•
Evaluation of the incidence rate of GnRH antagonist reports (see
Section 8.5.1) that occurred within the 2 weeks (± 2 days) following
first drug administration will be descriptively compared to the incidence
rate within the 2 weeks (± 2 days) after each subsequent drug
administration
•
Evaluation of the incidence rate of GnRH antagonist reports that
occurred within 2 weeks (± 2 days) following drug administration will
be descriptively compared to the incidence rate within the 2 weeks
(± 2 days) prior to each scheduled visit.
Pharmacokinetics: 
Leuprolide serum concentrations will be analyzed for characterization of 
burst and trough serum concentrations. Leuprolide concentrations will be 
associated with changes in LH, FSH, and testosterone/estradiol changes over 
time to characterize the pharmacokinetic/pharmacodynamic (PK/PD) 
relationship.  
Safety: 
Statistical analysis of safety will be descriptive only. Continuous data will be 
summarized in tables listing the mean, standard deviation, minimum, 
maximum, and number of subjects in each part of the study. Changes in 
GnRH antagonist reports over time will be evaluated by a comparison of 
reported reactions for the 2 weeks after dosing to those reported at each of 
the scheduled visits. Categorical data will be summarized in tables listing 
frequency and the percentage of subjects. All data will be listed by subject.

6. INTRODUCTION
6.1 Background
Gonadotropin releasing hormone (GnRH)-dependent Central Precocious Puberty (CPP) is 
characterized by early pubertal changes accompanied by advanced bone age, accelerated growth 
velocity and GnRH-axis activation (Antoniazzi 2004; Kim 2013). Determining if the cause of 
CPP is idiopathic (genetic/undetermined) or organic (central nervous system tumor/lesion) is 
essential to treatment. Idiopathic CPP is more prevalent in females; whereas, in males 
distinguishable organic pathologies are more common (Fuqua 2013; Kaplowitz 1999). Both 
forms of CPP may benefit from GnRH agonist (GnRHa) therapies. 
The current standard for differential diagnosis for CPP is the GnRHa stimulation test (Carretto 
2014, Chi 2012). For this test, a dose of 20 µg/kg body weight of aqueous leuprolide acetate is 
administered; serum luteinizing hormone (LH), follicle stimulation hormone (FSH) and 
testosterone/estradiol are measured 30 minutes post infusion (Houk 2008; Chi 2012). Serum 
concentrations of LH ≥ 5 mIU/mL at 30 minutes are diagnostic for CPP (Houk 2008). 
Supportive diagnostic criteria for CPP include a combination of clinical and physical aspects 
before initiating treatment (Antoniazzi 2004). These tests include determining the Tanner stage 
(Marshall 1969) and bone age. Bone age is determined via X-ray of the non-dominant hand, 
from which bone length and epiphyseal plate size are used by the Greulich and Pyle method to

determine bone age (Antoniazzi 2004, Fuqua 2013). A bone age ≥ 1.5 years of chronologic age 
indicates accelerated bone growth and CPP. 
Leuprolide acetate is a GnRHa that inhibits pituitary gonadotropin secretion and suppresses 
testicular and ovarian steroidogenesis. In the original studies with leuprolide acetate in subjects 
with CPP, daily subcutaneous (SC) administration was shown to decrease concentrations of LH 
and FSH in pediatric patients (Kappy 1988). These inhibitory effects are reversible when drug 
therapy is discontinued. Since that time, new formulations of leuprolide acetate have been 
developed to allow for less frequent dosing.  
Leuprolide acetate has been approved as an injection formulation (Lupron Depot-PED, Product 
Insert-06/2013) for treatment of CPP. This formulation can be administered as once monthly 
intramuscular injection at doses of 7.5 mg, 11.25 mg, or 15 mg, or as once every three months at 
doses of 11.25 mg or 30 mg. 
Leuprolide acetate is also available as a suspension formulation for SC injection (under the brand 
name ELIGARD®), which is currently approved for palliative treatment of advanced prostate 
cancer (Product Insert-05/2014), up to a maximum dose of 45 mg administered every 6 months. 
The leuprolide acetate 45 mg in the study drug is in a controlled release injection solution 
formulation with the polymer Atrigel™ and has been used extensively in over 1 million 
administrations for the treatment of prostate cancer.  
Each different extended formulation of leuprolide acetate has different release characteristics to 
optimize the GnRHa activity. For example, clinical experience with leuprolide acetate has 
demonstrated prolonged testosterone suppression with daily administration of as little as 1 mg, or 
after administration in depot formulations at intervals of one month or longer (Chrisp 1991). The 
pharmacokinetics of GnRH agonists, includes an initial 'flare-up' of the pituitary-gonadal axis, 
followed by a reduced luteinizing hormone secretion by desensitization of pituitary GnRH 
receptors. During the first weeks of treatment, clinical signs of puberty, such as vaginal bleeding, 
may occur. This is a common initial effect of drugs with leuprolide acetate. The new 
signs/symptoms of puberty can continue beyond the second month of treatment. In the Package 
Insert for Eligard under Section17 (Information for Patients), it includes information, as with 
other GnRH agonists, that patients may experience hot flashes (flares) after injection and in the 
first few weeks of treatment may also experience increased bone pain, increased difficulty in 
urination, and the onset or aggravation of weakness or paralysis and that these symptoms should 
be reported. Patients should also be told that the injection site may have transient 
burning/stinging, slight pain, bruising, and redness that are usually mild and reversible. Rarely 
allergic reactions do occur and should be reported immediately.  
Benefits of leuprolide acetate for the treatment of CPP include increases to or restoration of 
projected adult height, and protection from the psychosocial harm associated with clinically 
significant early puberty (Kim 2013). Leuprolide acetate has been shown to be safe and effective 
during treatment periods from three months to one year at doses up to 20 mg/day in humans 
(Yamanaka 1985). 
ELIGARD® has not been approved for use in subjects with CPP; therefore, in this study, it will 
be considered as an investigational product or the study drug.

6.2 Rationale 
The purpose of this study is to determine the safety, efficacy and tolerability of leuprolide acetate 
45 mg injections in children with CPP. Efficacy is defined as suppression of serum LH 
concentration to levels below 4 mIU/mL. GnRH agonists are the only products approved for use 
in CPP. ELIGARD® 45 mg is an injectable suspension of leuprolide acetate administered 
periodically (currently every 6 months) to provide controlled release characteristics, which has 
been shown to have a favorable safety profile in adults. The 45 mg injectable formulation of 
leuprolide acetate is expected to provide convenience for children with CPP by less frequent 
office visits and thus greater compliance for maintenance of an effective and safe dose of a well-
described GnRH agonist.  
An adaptive protocol design has been chosen for this study due to the remote possibility that, in 
children with CPP, the controlled release characteristics of the leuprolide acetate 45 mg 
formulation may not completely suppress LH levels after 6 months but would be able to provide 
adequate suppression after 5 months. Therefore, the Part A of this design will evaluate the 
efficacy, tolerability and safety of administration of the leuprolide acetate 45 mg after 
2 administrations with a dose interval of 6 months. Since this formulation has not been 
administered to children, who may not metabolize the injectable formulation of leuprolide in the 
same manner as adults, a Part B extension is planned as a contingency in which the study drug 
will be administered at shorter intervals (5 months). The progression to Part B extension of the 
study will be based on levels of LH suppression at 6 months after the first dose, in a subset of 
subjects, as evaluated by the a Data Safety Monitoring Board (DSMB) and Sponsor.

8. INVESTIGATIONAL PLAN
8.1 Overall Study Design and Plan
This will be an adaptive design study conducted in two parts as illustrated in Figure 1. 
Figure 1 
Study Design 
Subjects will only receive Injections #3 and #4 if Part B is conducted, based on Part A interim data. 
Part A: 
This will be a multi-center, open-label, single-arm 12-month study. Pediatric subjects with CPP 
will receive their first SC injection of the study drug (leuprolide acetate 45 mg for injectable 
suspension) at the start of the study and the second injection at the Month 6 visit. Subjects will 
return to the clinic periodically for 12 months from the start of dosing for assessment of efficacy, 
safety and pharmacokinetics (PK). 
An independent DSMB will review the safety of the drug throughout the study. 
An interim analysis of LH suppression from the GnRHa stimulation test results will be 
conducted after approximately 40% of the 40 subjects anticipated to complete 6 months of 
assessments have data through the Month 6 visit (N = approximately 16). Based on this analysis, 
if LH concentrations after the GnRHa stimulation test are suppressed to < 4 mIU/mL in < 85% of 
these subjects, then Part B of the study will be invoked. All subjects still undergoing therapy in 
the Part A of the study and those yet to enroll in the study, if eligible, will be asked to participate 
in the Part B extension study for additional dosing at shorter intervals. The progression to Part B 
extension will be based on evaluations by the DSMB and Sponsor.  
Part B Extension: 
This part of the study will be conducted based on analysis of interim data from Part A. 
NOTE: Because the interim analysis will only provide data from a very small sample size 
informing the decision to conduct Part B of the study with a 5-month dosing interval, ALL new 
subjects being enrolled into the study will begin with Part A of the study with the first 6-month 
dosing interval before proceeding to Part B. In this manner, there will be adequate data for 
comparison of dosing intervals for assessment of optimal efficacy. 
If invoked, this will be a multi-center, open-label, single-arm extension following Part A. Only 
subjects who have received the second injection of the study drug in Part A will be permitted to

Page 21 of 60 
enter Part B extension. Injections #3 and #4 will be administered in 5-month intervals after 
Injection #2 in Part A. The dosing interval will be dependent on emerging data from Part A. 
Subjects will return to the clinic periodically up to approximately an additional 10 months from 
start of Part B for efficacy, safety and PK assessments. 
8.1.1 Duration of Study 
In Part A, after a 28-day screening period, each subject will participate in the study for 48 weeks. 
Six months after Injection #1 in Part A, subjects will receive Injection #2 of the study drug. 
There will be a total of 7 study visits during Part A for a total duration of approximately 
12 months.  
Part A of the study is expected to take up to 24 months from first subject first visit (FSFV) to last 
subject last visit (LSLV), if Part B is not conducted. 
After the interim analysis, if the DSMB and the Sponsor make the decision to conduct Part B of 
the study then all currently enrolled eligible subjects and all newly enrolled subjects will receive 
a total of 4 injections of the study drug. Subjects who have gone beyond the Month 11 visit will 
not be considered eligible to participate in Part B extension as they would be considered to be 
out-of-window for Injection #3.  
If Part B of the study is invoked, the study length (for both Parts A and B) will be expected to be 
extended for approximately 10 more months for a total of approximately 34 months from FSFV 
(Injection #1) to LSLV. With the addition of Part B, commitment of each subject in the study 
will increase from 12 months to 21 months. 
8.1.2 Number of Subjects 
Approximately 60 pediatric subjects with CPP will be enrolled in this multicenter study so that 
approximately 40 subjects complete 6 months of the study. 
If Part B extension of the study is invoked, it is expected that approximately 27 subjects will 
complete outcome assessments to the Month 21 visit (5 months after the 4th study drug 
administration).  
8.1.3 Subject Recruitment/Enrollment 
Subjects will be evaluated for study inclusion only after written ICF and Assent (if required) has 
been obtained. Prior to enrollment during the Screening Period, each subject’s 
inclusion/exclusion criteria information, including current and recent medications, will be 
reviewed to verify that the subject qualifies for the study and is not receiving any prohibited 
medications/treatment. After meeting all of the inclusion and none of the exclusion criteria, 
subjects will be eligible to enroll in the study.  
8.1.4 Randomization 
There is only one Investigational Product (referred to as study drug) in this study; hence, there is 
no randomization to study groups. 
8.2 Study Population 
Deviations from the inclusion or exclusion criteria are not allowed because they can potentially 
jeopardize the scientific integrity of the study, regulatory acceptability, and/or subject safety.

Therefore, strict adherence to the criteria as specified is essential. Subjects whose 
parent/guardian(s) have provided consent along with Assent (as required) to participate in the 
study, but fail to meet all study eligibility criteria will be considered screen failures. Screen 
failure subjects are not eligible for re-screening. Retesting of laboratory safety parameters, if 
considered necessary by the investigator, to support the re-evaluation of a medical condition or 
serious intercurrent illness that, in the opinion of the Investigator, would make it undesirable for 
the subject to participate in the study, may be permitted upon consultation with the Medical 
Monitor.  
8.2.1 Subject Inclusion Criteria 
Subjects must meet all of the following criteria to be eligible for participation in the study: 
1. Females age 2 to 8 years (inclusive) or males age 2 to 9 years (inclusive)

Subjects who discontinue from the study will be treated as per the Investigator’s discretion and 
standard of care for children with CPP. 
8.3 Investigational Product (Study Drug) 
8.3.1 Treatments Administered 
8.3.1.1 During Study Period 
In Part A of the study each subject will receive a total of 2 single doses of the study drug 
administered as a SC injection into the abdominal area over the 12 month study period. The 
2 injections of the study drug will be at 6-month intervals: one at Baseline (Day 0) and one at the 
Month 6 visit (24 weeks).  
If Part B extension is conducted, then subjects will receive 2 additional SC administrations of the 
study drug at 5-month intervals: one at the Month 11 visit and one at the Month 16 visit.  
8.3.2 Description of Investigational Product 
The study drug, manufactured by TOLMAR, is a suspension of leuprolide acetate (ELIGARD®) 
for SC injection, provided in a single-use kit. The kit consists of a two-syringe mixing system, a 
sterile needle (18-gauge, 5/8-inch), a silicone desiccant pouch to control moisture uptake. Each 
syringe is individually packaged. One syringe contains the ATRIGEL® Delivery System and the 
other contains leuprolide acetate. When constituted, the study drug is administered as a single 
dose.  
8.3.3 Method of Blinding 
There will be no blinding of the study drug. 
8.3.4 Investigational Product Storage 
The Investigational Product or study drug is to be stored in a secure location. The kit should be 
stored refrigerated at 2°C to 8°C (36°F to 46°F).  
Prior to the injection time, the two-syringe mixing system kit should be brought to room 
temperature at least 30 min prior to administration. The provided Pharmacy Manual contain 
detailed instructions on the necessary steps for mixing of the leuprolide acetate prior to 
administration. Once the contents of the two syringes are mixed, the final product must be 
administered in ≤ 30 minutes.  
8.3.4.1 Administration 
The specific location chosen for the study drug should be an area with sufficient soft or loose 
subcutaneous tissue (eg, upper- or mid-abdominal areas). Avoid areas with brawny or fibrous 
subcutaneous tissue or locations that could be rubbed or compressed (eg, with a belt or clothing 
waistband).  
Topical or local anesthetic to “numb” the study drug injection site is permissible but must be 
recorded as a concomitant medication including the time of its administration.

Page 25 of 60 
8.3.4.2 Treatment Compliance 
All study drug injections will be administered by study staff at the clinic. The date and time of 
doses administered in the clinic will be recorded in the source documents.  
8.3.5 Method for Assigning Subject Numbers 
A unique subject number will be assigned to each subject. Neither subject initials nor other 
private health information (PHI), except date of birth and sex, will be collected on study 
documents.  
8.3.6 Investigational Product Accountability 
The accounting for the receipt, administration and disposition of all investigational product/study 
drug by each clinical site is required. This information will consist of the date the study drug has 
been received at the clinical site, date administered, the subject number, and if and when 
investigational product/study drug was destroyed or returned. The Investigator must maintain a 
complete and current dispensing and inventory record in accordance with the Protocol and any 
applicable laws and regulations. Throughout the study, Investigational Product/study drug 
accountability review and reconciliation for the study drug must be maintained, and any 
discrepancies must be investigated and their resolution documented. 
Inventory records must be readily available for inspection by the study monitor and/or auditor, 
and open to regulatory authority inspection at any time. 
All study drug receipt, inventory, dispensing, dosing and reconciliation records will be 
maintained in compliance with FDA and local regulations. 
8.3.6.1 Accountability and Investigational Product Use 
The Investigator agrees to ensure that dispensation of the study drug occurs only at the study 
site(s) listed on the Form FDA 1572 (or investigator agreement/statement). The Investigator or 
designee also agrees that only subjects enrolled in the study may receive administration of the 
study drug at the clinical site. Clinical supplies may not be used for any purpose other than as 
stated in this Protocol. 
The dispensing of all the study drug will be recorded in a dispensing log. The subject number, 
time of administration, and the initials and date of the person dispensing the medication will be 
documented on this form. The dispensing log will include the study drug identification lot 
numbers of the kit and both syringes.  
8.3.6.2 Disposition of Used Supplies 
The Investigator is responsible for accounting for all used study drug. This information will be 
recorded on the Drug Dispensing Log or other appropriate study drug inventory log. Used 
supplies should be disposed of in an appropriate manner according to institutional policy. 
8.3.6.3 Inventory of Unused Supplies 
The Investigator is responsible for accounting for all unused study drug. Periodically throughout 
and at the conclusion of the study, an inventory of unused study drug will be conducted by a 
representative of the Sponsor.

8.3.7 Concomitant Medications 
All concomitant medications including over-the-counter (OTC) medications, herbal, botanical 
and nutritional supplements used during the study must be recorded in the appropriate eCRF 
(Concomitant Medication Form) along with the indication for which it was used. The generic 
name of the medications should be specified along with the dosage, frequency and duration of 
treatment.  
Any medication considered necessary for the subject’s welfare, which is not expected to interfere 
with the PK assessment of study drug, may be given at the discretion of the Investigator.  
8.3.7.1 Permitted Medications 
Medications that are used to treat acute conditions are permitted. Any medications that are used 
for previously identified conditions may be continued but must be recorded in the medical 
history and in the list of concomitant medications.  
Local or topical anesthetics may be used and must be recorded as a concomitant medication with 
the generic name, time of administration, type and route of administration.  
8.3.7.2 Prohibited Medications 
Subjects shall receive no other GnRH or GnRH agonist therapy for any indication during this 
study. No additional hormonal therapies of any kind are permitted during this study. Subjects 
shall not receive any concomitant medications that, in the Investigator’s opinion, have been 
associated with seizures or convulsions or will put the child at risk of seizures or convulsions. 
8.3.7.3 Concomitant Procedures 
Any diagnostic, therapeutic or surgical procedures performed during the study must be recorded 
in the eCRF, including the date, indication, description of the procedure(s), any clinical findings, 
and outcome. 
8.4 Study Procedures 
The by-visit schedule of study activities are provided in Table 1 and Table 2 for Part A and in 
Table 3 for Part B. Every attempt should be made to have each subject attend each visit as 
scheduled.

8.4.2 Demographic Information 
Demographic and baseline characteristics, including date of birth, sex, race (American Indian; or 
Alaska Native; Asian; Black or African American; Native Hawaiian or Other Pacific Islander; 
White), and ethnicity (Hispanic or Latino; Not Hispanic or Latino) will be collected. 
8.4.3 Medical History 
Relevant medical history will be collected including prior and ongoing medical illnesses, 
conditions, and surgical procedures within the 24 months prior to enrollment. 
8.4.4 Prior and Concomitant Medications / Treatments 
All prior and concomitant medications, as well as any diagnostic, therapeutic, or surgical 
procedures performed, will be recorded from the time of signing the ICF/Assent Form (if 
required) throughout the subject’s participation in the study. 
8.4.5 Vital Signs 
Vital signs will be measured after the subject has been in a seated or supine position for 
5 minutes. Vital sign assessments will include the measurement of blood pressure (mm Hg), 
heart rate (beats per minute), respiration rate (breaths per minute), and temperature (oral, 
tympanic, or temporal; °C or °F). 
8.4.6 Weight  
Body weight (kg) will be measured at every visit. 
8.4.7 Height 
Standing height will be recorded with a calibrated stadiometer (eg, “Harpenden” stadiometer) 
that has increments in millimeters (mm) and a functional Frankfort Plane perpendicular to the 
standing surface. Preferably, the same stadiometer and the same health care provider trained in 
the use of the stadiometer will do the repetitive measurements on any subject in the study.  
The feet must be flat and either the knees or feet together in the center of the measuring board, 
making sure the legs are straight. The position of the legs is important. The mid-axillary line 
should be perpendicular to the base of the board. The subject should be looking straight ahead. In 
overweight, obese and older children, when the head is placed in proper position, according to 
the Frankfort Plane, there may be a space between the back of the child's head and the back of 
the measuring board. Use the Frankfort Plane on the stadiometer to determine the actual standing 
height to ± 1 mm.  
8.4.8 Physical Examination 
A complete physical exam (PE) will be performed by study personnel who are qualified to 
perform such examinations. At a minimum, the PE should include the cardiovascular system, the 
respiratory system, and the abdomen.  
Thereafter, a directed or targeted PE will be performed covering body systems related to the 
disease, including Tanner stages, and/or to assess any ongoing AEs.

8.4.9 Tanner Stages 
Sexual development in puberty will be assessed by Tanner staging, a system developed by 
Marshall and Tanner (1969) to categorize pubertal maturation. See Appendix 13.2 for details on 
the Tanner stages. Note any changes or onset of menses.  
8.4.10 Clinical Laboratory Assessments 
Clinical laboratory assessments (hematology, clinical chemistry, fasting serum lipids, hepatitis B 
& C, and urinalysis parameters) are listed in Appendix 13.1. Urinalysis assessments will be by 
“dipstick” assessments using urinalysis kits that will be provided to the sites by the Sponsor and 
evaluated locally. All other laboratory assessments will be from the blood samples collected at 
the appropriate assessment times and analyzed by a central laboratory. 
8.4.11 Pregnancy Test 
Urine pregnancy tests will be performed on female subjects. All female subjects must have a 
negative pregnancy test prior to receiving each injection of study drug. The pregnancy test will 
also be performed at End of Treatment in Part A or Part B extension (if invoked), and at the 
discretion of the Investigator.  
8.4.12 Hand and Wrist X-Ray 
A single X-ray of the non-dominant hand and wrist will be obtained periodically throughout the 
study to determine bone age using a Greulich and Pyle Atlas. A local reader will determine study 
eligibility during screening. All X-rays taken at designated study visits will be sent to a blinded 
central reader for evaluation of bone age; however, these evaluations will not be used to verify 
eligibility (eg, overrule local reader) for subject participation in the study. 
8.4.13 Basal LH, FSH, Testosterone/Estradiol Concentrations 
Blood samples for serum LH, FSH, testosterone (males) / estradiol (females) concentrations (as 
appropriate) will be collected at the appropriate assessment times and analyzed by a central 
laboratory according to current validated assays. It is important that ALL these samples are 
obtained BEFORE each study drug injection.  
These samples MUST be collected BEFORE the GnRHa stimulation tests. 
Blood samples will be collected and processed at the clinical site, and then shipped to the Central 
Laboratory for analysis according to the instructions provided in a Central Laboratory Manual.  
Serum LH and FSH concentrations will be measured at the Central Laboratory using current 
validated chemiluminescent microparticle immunoassay with a lower sensitivity range to at least 
0.5 mIU/mL (such as ARCHITECT System, Abbott Laboratory Diagnostics, USA). The lower 
limit of detection for testosterone/estradiol will be at least 3 ng/dL and 7.5 pg/mL, respectively. 
In addition, samples will be batched and analyzed by LC-MS/MS for publication purposes only. 
8.4.14 Abbreviated GnRHa Stimulation Test 
Baseline blood samples for serum LH, FSH, and testosterone/estradiol concentrations MUST 
first be obtained PRIOR to the start of the GnRHa stimulation test. A standard dose of 20 µg/kg 
body weight of aqueous leuprolide acetate will be administered SC. Blood samples to measure 
serum LH, FSH and testosterone/estradiol concentrations will be obtained again 30 minutes later.

Serum LH and FSH concentrations will be measured using current validated chemiluminescent 
microparticle immunoassay, as described in Section 8.4.13 
8.4.15 Pharmacokinetic Assessment 
All blood samples for analysis of leuprolide concentrations will be processed by a central 
bioanalytical laboratory. Instructions for collecting, processing, storing, and shipping blood 
samples will be provided in a separate PK Sample Collection, Handling and Shipping Manual. 
A validated bioanalytical liquid chromatography-tandem mass spectrometry (LC/MS/MS) 
method will be used to measure leuprolide concentrations in serum samples. 
8.5 Safety Evaluation 
8.5.1 Safety Parameters 
Safety parameters to be measured/assessed include eligibility assessments, medical history, vital 
signs, physical examinations, clinical laboratory tests, and pregnancy tests. Any abnormal 
hematology, serum chemistry, serum lipid, or urinalysis parameters considered clinically 
significant by the Investigator will be captured as AEs. 
Subjects will be monitored throughout the study for AEs, as well as for changes in clinical status, 
vital signs, and laboratory data. Any non-serious AEs occurring from the time the ICF and 
Assent forms, if required, are signed until just prior to receiving the first injection of study drug 
will be considered as non-TEAEs unrelated to study drug administration.  
Serious adverse events (SAEs) that occur as a result of study-mandated procedures during the 
time period after the ICF and Assent forms are signed, as appropriate, but prior to receiving the 
first injection of study drug will be collected but not designated as TEAEs. 
In order to evaluate changes in the acute (within two weeks of administration) and chronic 
hormonal responses associated with GnRH antagonist treatments over time,  subjects (or their 
parents/guardians) will be asked two weeks (14 days ± 2 days) after every study drug 
administration (by telephone contact), and at each scheduled visit, the following question(s):  
•
How have you felt in the last two weeks?
or alternatively (if the parent or guardian is answering on behalf of the subject) 
•
How has your child felt in the last two weeks?
Investigators will record any adverse events that are reported at that time. 
In addition the investigators will categorize the more specific responses that have been identified 
in the table (Table 4), which are often associated with GnRH antagonist injectable treatments. If 
the subject (or parent/guardian) does not report any condition (within the last two weeks) that fits 
into the Table 4 categories, the Investigator will check the response that no conditions associated 
with GnRH antagonists were reported (“NO”). If any of the conditions reported by the subject 
(or parent/guardian) fit into one (or more) of the categories, then the Investigator will check 
“YES” for each applicable category. This reported information will be collected by completing

must be completed prior to any study drug administration to evaluate the chronic reports.  
8.5.2 Investigator/Sponsor Safety Review 
The Medical Monitor will be responsible for the ongoing evaluation of safety throughout the 
study. The study will be reviewed for safety on a continual basis. The Medical Monitor will have 
access to all laboratory data and will review all SAEs. Clinical judgment by the Medical 
Monitor, in consultation with the Investigator and Sponsor, will be used to determine if the study 
should be stopped or suspended at any time for additional review of subject safety. The Medical 
Monitor will make an initial determination of the expectedness of an event based on the 
reference safety information (Investigator Brochure and ELIGARD® Package Insert). The 
Medical Monitor may present summary of safety information to the DSMB. 
8.5.3 Data Safety Monitoring Board 
An independent DSMB will review the safety and efficacy of the drug throughout the study. The 
frequency of subject evaluations will be at least quarterly. The full extent of responsibilities of 
the DSMB will be defined in their charter.  
The DSMB will review the data from the interim analysis looking at LH suppression from the 
GnRHa stimulation test in a subset of subjects completing the 6-month assessments to make 
recommendations on the progression to the Part B extension study. See Section 9.2.4 for criteria 
for the interim analysis data.

8.5.4 Definition of Terms 
8.5.4.1 Adverse Event Definition 
An AE is defined as any untoward medical occurrence associated with the use of a drug in 
humans, whether or not considered drug related (21 CFR 312.32 (a)). An AE can, therefore, be 
any unfavorable and unintended sign (eg, an abnormal laboratory finding considered clinically 
significant by the Investigator), symptom, or disease temporally associated with the use of a 
drug, without any judgment about causality. For this protocol, any unfavorable and unintended 
sign, symptom, or disease occurring after signature of Informed Consent/Assent will be collected 
as AEs.  
8.5.4.2 Suspected Adverse Reaction Definition 
A suspected adverse reaction is defined as any AE for which there is reasonable possibility that 
the drug caused the AE (21 CFR 312.32 (a)). 
8.5.4.3 Unexpected Adverse Event Definition 
An AE or suspected adverse reaction is considered unexpected if it is not listed in the 
ELIGARD® Package Insert, or is not listed in the Investigator Brochure. 
8.5.4.4 Serious Adverse Event Definition 
An SAE is defined as any untoward medical occurrence at any dose of study drug that results in 
any of the following outcomes (see FDA 21 CFR 312.32 and/or ICH E6 for Good Clinical 
Practice: Glossary of Terms): 
•
Death
•
A life-threatening adverse event
NOTE: The term “life-threatening” in the definition of “serious” refers to an event in 
which the subject was at risk of death at the time of the event; it does not refer to an 
event, which hypothetically might have caused death if it were more severe.  
•
Inpatient hospitalization or prolongation of existing hospitalization
•
A persistent or significant disability/incapacity (substantial disruption of the ability to
conduct normal life functions)
•
A congenital anomaly/birth defect
The following events should also be considered as serious: 
•
Important medical events: Events that are not immediately life threatening or do not
result in death or hospitalization, but they do require urgent and intensive intervention to
prevent one of the other outcomes listed in the definition above (eg, intensive treatment at
home or in an emergency room for bronchospasm or seizure and a persistent high fever
with temperatures over 101°F [38°C]).
8.5.5 Reporting of Adverse Events 
All AEs that are observed by the Investigator or one of his/her medical collaborators, or reported 
by the subject, will be reported even if they are potentially attributable to unrelated medical 

CPP Treatment with Leuprolide Acetate 
TOLMAR Inc. 
Clinical Study Protocol: TOL2581A FINAL 
25 August 2015 
Version 3.0

Page 37 of 60 
conditions or other medications the subject may be taking. The information recorded for AEs 
will include start date, a description of the AE, severity, causal relationship to Investigational 
Product/study drug, action taken, outcome of the event (including any treatment and/or 
hospitalization), and stop date. In addition, start time will be collected for events beginning on 
the day of the first injection. 
Medical conditions or diseases present before a subject is enrolled in the study are only 
considered AEs if they worsen after the subject is enrolled. 
For each AE, the seriousness, severity, and causal relationship to study drug will be assessed and 
entered in the source document. All items on the AE page of the eCRF should be completed for 
each AE.  
Surgical procedures themselves are not AEs; they are therapeutic measures for conditions that 
require surgery. The condition for which the surgery is required is an AE, if it occurs or is 
detected during the study period. Planned surgical measures and the conditions leading to these 
measures are not AEs, if the condition(s) was (were) known before the study treatment. In the 
latter case, the condition should be reported as medical history.  
8.5.5.1 Severity of Adverse Events 
The National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) 
grading scale uses Grades 1 through 5 to provide unique clinical descriptions of severity for AEs. 
Each AE will be rated according to NCI-CTCAE (version will be specified in the statistical 
analysis plan [SAP]) severity grading scale as outlined in Table 5. A complete description of 
each grade of the NCI-CTCAE rating system can be found on the NCI website (NCI-CTCAE 
version 4.0, 2010). 
Table 5 
National Cancer Institute Common Toxicity Criteria for Adverse Events 
Severity Grading Scale 
Grade 1 
Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated. 
Grade 2 
Moderate; minimal, local, or noninvasive intervention indicated; limiting age-
appropriate instrumental ADLa. 
Grade 3 
Severe or medically significant but not immediately life-threatening; hospitalization 
or prolongation of hospitalization indicated; disabling; limiting self-care ADLb. 
Grade 4 
Life-threatening consequences; urgent intervention indicated. 
Grade 5 
Death related to AE. 
ADL: Activities of Daily Living 
a.
Instrumental ADL refer to preparing meals, shopping for groceries or clothes, using the telephone, managing
money, etc.
b.
Self-care ADL refer to bathing, dressing and undressing, feeding self, using the toilet, taking medications, and
not bedridden.
Source: NCI-CTCAE version 4.0, 2010 
An AE that is assessed as severe should not be confused with an SAE. An event is defined as 
‘serious’ when it meets one of the pre-defined outcomes as described in Section 8.5.4.4.

8.5.5.2 Criteria for Determining Relationship of Adverse Events to Investigational 
Product 
All AEs must be rated for their causal relationship to study drug according to the categories 
outlined in Table 6. 
Table 6 
Criteria for Determining Relationship of Adverse Event to Investigational 
Product 
Adverse 
Event 
Relationship 
Definition 
Criteria 
Not Related 
This category applies to those 
AEs that the Investigator, 
after careful consideration, 
believes are clearly due to 
extraneous causes (disease, 
environment, etc) and are not 
related to the administered 
investigational product. 
An adverse experience may be considered not 
related if, for example, the following apply: 
• It does not follow a reasonable temporal sequence
from administration of Investigational Product
• It could readily have been produced by the
subject’s clinical state, environment or toxic
factors, or other modes of therapy administered to
the subject
• It does not follow a known pattern of response to
Investigational Product
Related 
This category applies to those 
AEs that the Investigator 
believes are related to the 
administrated Investigational 
Product. 
An AE may be assigned as related if, for example, 
the following apply: 
• It follows a reasonable temporal sequence from
administration of Investigational Product.
• It could not be reasonably explained by the
known characteristics of the subject’s clinical
state, environmental or toxic factors, or other
modes of therapy administered to the subject.
• It disappears or decreases on cessation or
reduction in dose of study drug and recurs with
re-exposure.
­ NOTE: This is not to be construed as
requiring re-exposure of the subject. 
• It follows a known pattern of response to the
Investigational Product.
8.5.6 Serious Adverse Events 
All SAEs occurring after administration of study drug and within 6 months following last dose of 
study drug must be reported to the representatives of TOLMAR within 24 hours after the 
Investigator or site personnel have been informed or first becoming aware of the event. All 
events that meet the definition of an SAE or suspected unexpected serious adverse reactions 
(SUSAR) that occur as a result of study mandated procedures during the time period after the 
subject signs the ICF but prior to receiving the first infusion of study drug must also be reported.

Page 39 of 60 
8.5.6.1 Reporting of Serious Adverse Events 
When an SAE or SUSAR occurs, the Investigator or designee must log into the electronic data 
capture (EDC) system and complete the SAE Report form within 24 hours of first becoming 
aware of the SAE. All SAEs (including deaths of any cause) that occur after administration of 
study drug and within 6 months after the last administration of study drug in Part A, or within 5 
months after the last administration of study drug in Part B is invoked, whether or not considered 
related to study drug must be reported. The Investigator must also report SAEs to the Sponsor or 
representative (contract research organization [CRO]) and to the IRB/IEC as required by local 
and national laws. The Investigator must maintain documentation of all communications to and 
from the IRB/IEC. The SAE Report from the site should include date and time of onset, 
description of event, severity, duration, outcome, etiology, relationship to study drug, action 
taken and other relevant details as available. The Investigator is also responsible for updating the 
SAE Report Form as additional information becomes available. The Investigator may be 
requested for additional follow-up information by the Sponsor or the pharmacovigilance service 
provider in order to have more complete information for regulatory reporting.  
All SAEs/SUSARS will be monitored by the CRO Medical Monitor or pharmacovigilance 
service provider prior to submission to the regulatory authorities. Events associated with this 
clinical trial will be recorded in the ELIGARD® global safety database that is maintained for 
reporting and analysis. 
The Sponsor will adhere to all AE regulatory reporting requirements in accordance with local 
regulation and local authorities.  
Additional safety instructions will be provided to clinical sites including contact numbers and 
schedules to report all AEs, SAEs and SUSARs associated with this study. 
8.5.6.2 Follow Up of Adverse Events by Investigator 
After the initial SAE report, the Investigator is required to proactively follow each subject and 
provide further information to CRO on the subject’s condition. Any AEs related to study drug 
will be followed for 28 days or through resolution, stabilization, until deemed clinically 
insignificant, or until the subject is lost to follow-up. For SAEs, follow-up is required on an 
expedited timeline, within 24 hours of the initial report, as described in Section 8.5.6.1.  
New or updated information will be recorded in the “SAE” eCRF. The medical monitor and 
TOLMAR will be notified of the SAE within 24 hours as per the CRO’s established processes 
(Section 8.5.6.1). 
8.5.7 Pregnancies 
If a subject becomes pregnant at any time after the first injection, she must NOT receive the 
subsequent injections.  
Pregnancies are not considered to be AEs or SAEs; however, pregnancies will be followed 
through to outcome. If a pregnancy occurs, the Investigator or designee must complete the 
Pregnancy Report form within 24 hours of first becoming aware of the pregnancy. In 
pregnancies that progress to term, any congenital abnormalities in the offspring of a subject who 
received study drug should be reported as an SAE.

8.6.20 Study Termination
The clinical study may be stopped at any time at the discretion of the Sponsor or by regulatory 
authorities (IRB/IEC or governing competent authority). The clinical study may be stopped if the 
extent (incidence and/or severity) of emerging effects/clinical endpoints is such that the 
risk/benefit ratio to the study population as a whole is unacceptable. 
Further recruitment in the study or at a particular site(s) may be stopped due to insufficient 
compliance with the Protocol, ICH-GCP and/or other applicable regulatory requirements, 
procedure-related problems, or if the number of discontinuations for administrative reasons is too 
high. 
Upon study termination, all site closure activities with the investigator or site staff, as 
appropriate, will be conducted in accordance with applicable regulations including ICH-GCP and 
sponsor procedures.  
After the completion of the study subjects will be managed for their underlying disease 
according to the local standard of care, and based on the subject’s previous medical history. 
Continued treatment will not be conducted as part of this protocol. 
9. STATISTICAL PLAN
Prior to the database lock, a finalized Statistical Analysis Plan (SAP) will be completed and 
approved. The SAP will contain a comprehensive explanation of the methodology used in the 
statistical analyses. The SAP will also contain the rules and data handling conventions that will 
be used to perform the analyses, and the procedure that will be used to account for missing data. 
9.1 Sample Size Determination 
To determine the percentage of subjects with suppression of serum LH to < 4 mIU/mL following 
treatment with leuprolide acetate 45 mg, it is estimated that approximately 40 subjects would be 
sufficient for assessment of Part A and approximately 27 subjects for Part B, if invoked. 
Approximately 60 subjects may be enrolled in the study in order to get an appropriate number of 
assessable subjects. 
The sample size was pragmatically determined based on the clinical trial size and response rate 
of other GnRH antagonists studies in CPP subjects.   
The descriptive finding that will conclude efficacy is that ≥ 80% of subjects will exhibit 
< 4 mIU/mL LH suppression. This is conservative, since the dropout rate is unknown, and it is 
anticipated that the percent of subjects suppressed is likely to be at least 85%. Thus, 85% 
suppression or 90% suppression might be reasonably expected. However, the drop out in this 

CPP Treatment with Leuprolide Acetate 
TOLMAR Inc. 
Clinical Study Protocol: TOL2581A FINAL 
25 August 2015 
Version 3.0 
CONFIDENTIAL 
Page 49 of 60 
study could be slightly more than 50%, if Part B is invoked, thus depending on whether only Part 
A is carried out or Part B is invoked, the final available sample size after drop out could vary 
between 25 and 50 subjects given the planned recruitment of 60 subjects. Suppression to 
< 4 mIU/mL in approximately 70% of the subjects is considered to be clinically important if the 
full expectations of all drop-out are completed. Thus, the study is thought to have a sufficient 
number of subjects. If 85% of subjects enrolled are found to be suppressed we would expect a 
lower 95% one sided confidence interval under a fully realized drop out scenario (ie, 25 final 
subjects) of slightly more that 70%.  
9.2 Statistical Methods 
The purpose of this study is to demonstrate suppression of LH at a level of < 4 mIU/mL at 
30 minutes after GnRHa stimulation in a majority of subjects (≥ 80%) who are treated with 
leuprolide acetate 45 mg in an injectable suspension. Descriptive outcomes for the primary and 
secondary efficacy variables will be used to evaluate the efficacy of this treatment.  
If suppression in ≥ 85% of the first 16 subjects to be evaluated at Month 6 is found, the study 
will terminate under Part A without the invocation of Part B as a follow-on adaptive dosing 
schedule. If study termination under Part A occurs, the criterion variable for adaptive change 
applied to the first 16 patients at six months, namely, percent of patients with < 4 mIU/mL 
suppression, will also function as the primary outcome variable when applied to all patients in 
the study. As was the case for evaluating adaptive change in design, an absolute descriptive 
rather than inferential statistical outcome will be used to assess efficacy for the primary outcome 
variable. Efficacy will be claimed if ≥ 80% of the subjects exhibit < 4 mIU/mL suppression.  
If suppression in < 85% of the first 16 subjects to be evaluated at Month 6 is found, the study 
will be adapted and Part B will be invoked. As would be the case if the study were to terminate 
with Part A, the percent of subjects with < 4 mIU/mL suppression will serve as the primary 
outcome variable under Part B. If < 4 mIU/mL suppression in ≥ 80% of the patients in the study 
at Visit 11 (Month 21) is found, efficacy will be claimed.  
9.2.1 Demographics and Other Baseline Characteristics 
Demographic variables will include age, race, ethnicity, sex, height, and weight. Subject 
demographics will be summarized with descriptive statistics, as appropriate.  
9.2.2 Efficacy Evaluations 
Primary Efficacy Endpoint 
•
Part A: the percentage of subjects with serum LH concentrations < 4 mIU/mL 30 minutes
following an abbreviated GnRHa stimulation test at the Month 6 visit
Leuprolide Acetate 45 mg will be considered effective for the treatment of children with
CPP if ≥ 80% of subjects exhibit LH suppression < 4 mIU/mL at Month 6
•
Part B Extension: the percentage of subjects with serum LH concentrations < 4 mIU/mL
30 minutes following an abbreviated GnRHa stimulation test at the Month 21 visit (5 months
after the Injection #4 of leuprolide acetate)

Leuprolide acetate 45 mg will be considered effective for the treatment of children with CPP 
if ≥ 80% of subjects exhibit LH suppression < 4 mIU/mL at the Month 21 visit (5 months 
after the last of 4 administrations of the study drug) 
NOTE:  If Part B extension is conducted, the primary efficacy endpoint for Part A will 
become a secondary efficacy endpoint of Part B. 
Secondary Efficacy Endpoint: Parts A & B 
•
The percentage of subjects with suppressed serum LH concentrations (< 4 mIU/mL)
30 minutes post GnRHa stimulation test at all assessed time points
•
Changes in height velocity (growth rate), and bone age advancement will be evaluated
relative to chronological age using descriptive statistics from baseline to end of study
•
Changes in physical signs of puberty as measured by changes in Tanner stages from
baseline to end of study
Exploratory Assessments: Parts A & B 
•
Bone age progression will be further evaluated using descriptive statistics and figures at all
assessed timepoints. Changes in bone age progression will be described for each individual
and for the ITT and PP population over the entire treatment period
•
Descriptive statistics will be used to describe changes in physical signs of puberty as
measured by changes in Tanner stages at each assessed timepoint. Changes in Tanner staging
will be described for each individual and for the ITT and PP population over the entire
treatment period.
•
The percentage of subjects with LH (< 4 mIU/mL), FSH (< 2.5 mIU/mL), estradiol
(< 20 pg/mL) or testosterone (< 30 ng/dL) suppression to prepubertal levels and serum
leuprolide levels at all assessed timepoints
•
Evaluation of the incidence rate of GnRH antagonist reports (see Section 8.5.1) that occurred
within the 2 weeks (± 2 days) following first drug administration will be descriptively
compared to the incidence rate within the 2 weeks (± 2 days) after each subsequent drug
administration
•
Evaluation of the incidence rate of GnRH antagonist reports that occurred within 2 weeks
(± 2 days) following drug administration will be descriptively compared to the incidence rate
within the 2 weeks (± 2 days) prior to each scheduled visit.
9.2.3 Pharmacokinetic and Pharmacodynamic Evaluations 
Leuprolide concentrations from each assessment time will be listed and descriptively analyzed. 
“By subject” serum concentrations versus time will be plotted on both linear and log scales. The 
characteristics of the burst of leuprolide concentration will be statistically described by the serum 
concentrations of leuprolide that are collected in the first week after each administration. The 
steady-state or baseline concentrations will be the statistical description of the leuprolide 
concentration collected at each assessment point at least one month after the first administration 
and prior to any GnRHa stimulation test or prior to subsequent administration of the leuprolide 
45 mg injection solution. An approximation of the AUC of the systemic leuprolide concentration 
between each dose and for the entire treatment period will be provided.

Each of the hormones assessed, and in particular, LH and FSH, and testosterone/estradiol will be 
statistically described for each assessment point and for changes in concentration from baseline 
values. The ratio of LH to FSH will be provided for each assessment point will be presented with 
an additional analysis of percent change from baseline for the ratio.  
For each assessment point the LH suppression from the GnRHa stimulation test results will be 
statistically described for the LH concentration 30 minutes after the agonist administration and 
the percent change in the LH concentration after the GnRHa stimulation test will be statistically 
compared to the baseline concentration of the GnRHa tests administered prior to the first dose. 
Additionally, the LH concentration 30 minutes after the agonist administration will be 
statistically contrasted to the leuprolide concentration at each assessment point to provide an 
assessment of the PK/PD relationship. Similar comparisons will be conducted to evaluate the 
relationship of leuprolide to changes in serum concentrations of FSH and testosterone/estradiol. 
9.2.4 Interim Analysis 
An interim analysis of LH suppression from the GnRHa stimulation test results will be 
conducted after approximately 40% of the 40 subjects anticipated to complete 6 months of 
assessments have data through the Month 6 visit (N = approximately 16). Based on these data, if 
LH concentrations after the GnRHa stimulation test are suppressed to < 4 mIU/mL in < 85% of 
these subjects, then Part B of the study will be invoked. All subjects still undergoing therapy in 
the Part A of the study and those yet to enroll in the study, if eligible, will be asked to participate 
in the Part B extension study for additional dosing at shorter intervals. The progression to Part B 
extension will be based on evaluations by the DSMB and Sponsor. Subjects that progress to 
Part B of the study will be provided information about Part B in an ICF and Assent Form (if 
required), which will be signed by appropriate parent/guardian(s) and the subject.  
9.2.5 Accounting for Missing Data 
Imputation of missing data will not be performed for baseline, efficacy, and safety endpoints. 
9.2.6 Safety Analyses 
A listing of all AEs, including SAEs and events leading to discontinuation, will be provided. The 
Data Management team will compile a list of all AEs based on the information entered in the 
eCRF. This listing will be sent to TOLMAR and the CRO Safety Department for the proper 
reconciliation of the study and safety databases. These listings will include: event term as 
reported, event term as coded with the Medical Dictionary for Regulatory Activities (MedDRA 
version(s) will be documented in the final Clinical Study Report), start date, start time (only for 
events beginning on the day of the first injection), stop date, outcome, seriousness, severity, 
relationship to Investigational Product, and action taken with Investigational Product. AEs 
recorded after signing of the ICF/Assent but PRIOR to the first injection will be reported as non-
TEAEs.  
The number and percent of subjects reporting AEs will be tabulated. Summaries will be 
presented by body system organ class (SOC) and preferred term (PT), and further by severity and 
relationship to the study drug.  
SAEs will be discussed within the clinical study report. Data collected pertaining to SAEs will be 
presented in data listings.

10.3 Primary Source Documents 
The Investigator will maintain adequate and accurate records for each subject who has 
appropriate consent/assent to participate in the study. Source documents such as hospital, clinic 
or office charts, laboratory reports, radiology reports, and signed ICF/Assent (if required) 
documents are to be included in the subject’s study chart. The Investigator will document the 
informed consent/assent process in the source documents; including documentation that the 
ICF/Assent were signed prior to the subject’s participation in the study and that a copy of the 
signed and personally dated ICF/Assent were provided to the parent/guardian(s) and subject, as 
appropriate. 
The Investigator must maintain primary source documents supporting significant data for each 
subject’s medical notes. These documents are considered source data and should include 
documentation of: 
•
Demographic information
•
Evidence supporting the diagnosis/condition for which the subject is being studied
•
General information supporting the subject’s participation in the study
•
General history and physical findings
•
Hospitalization or Emergency Room records (if applicable)
•
Each study visit by date, including any relevant findings/notes by the Investigator(s) or
designee, occurrence (or lack) of AEs, and changes in medication usage, including the
date and time infusion was started and ended
•
Any additional visits during the study
•
Any relevant telephone conversations with the subject regarding the study or possible
AEs
•
An original, signed ICF/Assent (if required) for study participation
The Investigator must also retain all subject-specific printouts/reports of tests and procedures 
performed as a requirement of the study. During monitoring visits the monitor will validate data 
in the eCRF against these sources of data. 
10.4 Study Monitoring 
This study will be closely monitored by the CRO throughout its duration. Monitoring will be in 
the form of personal visits with the Investigator and his/her staff as well as through other 
appropriate communications by telephone, FAX, email, or mail. It is the monitor’s responsibility 
to inspect the eCRF at regular intervals throughout the study to verify the completeness, 
accuracy, and consistency of the data, and to verify adherence to the Protocol, current ICH-GCP 
guidelines, and any applicable local regulations.

All data must be available in source documents before entry into the eCRF, and all data entered 
into the eCRF will be source data verified. Data that is required according to this Protocol is to 
be recorded in the eCRF. For data collected with the EDC system, source data documentation is 
defined as the first place the data are recorded. All source documents must be retained and 
retrievable at the site in study specific files. 
Every effort will be made to maintain the anonymity and confidentiality of subjects during this 
study. However, because of the experimental nature of this treatment, the Investigator agrees to 
allow representatives of the Sponsor as well as authorized representatives of the Regulatory 
Agencies, such as the FDA, to inspect the facilities used in this study and to inspect, for purposes 
of verification, the hospital or clinic records of all subjects enrolled into this study. The 
Investigator agrees to cooperate with the monitor to ensure that any problems detected during the 
course of these monitoring visits are resolved. 
Medical supervision for the conduct of this Protocol is the responsibility of the Investigator. The 
Principal Investigator must name all Sub-Investigators and may delegate certain tasks to named 
Sub-Investigators qualified and trained to do such tasks, but retains the overall personal 
responsibility for adequate supervision of study staff and ensuring that the study is conducted 
properly and in accordance with the design and intent herein. The Investigator must ensure that 
there is adequate training for all staff participating in the conduct of the study, including any new 
staff joining the study after it has begun. The Investigator must ensure that he or she has 
sufficient time to properly conduct and supervise the clinical study, and should develop a plan 
for the supervision and oversight of the study. A document outlining the specifics of the 
delegation will be maintained at the investigational site, in the study files, and will be updated as 
appropriate.  
Investigators are responsible for protecting the rights, safety, and welfare of subjects under their 
care during a clinical study (ICH E6 GCP Section 4). This responsibility should include: 
•
Providing adequate medical care to study subjects for any AEs, including clinically
significant laboratory values, related to the study
•
Providing decisions for medical care by a qualified physician who is an Investigator or
Sub-Investigator for the study
•
Conducting the study in compliance with the Protocol.
The Investigator should inform the subject's primary physician about the subject's participation 
in the study if the subject has a primary physician and the subject agrees to the primary physician 
being informed. The Investigator is responsible for ensuring that drugs and devices are available 
for treating possible medical emergencies. The Investigator is required to ensure compliance 
with respect to the investigational drug schedule, visit schedule, and procedures as required by 
the Protocol. The Investigator is responsible for ensuring that the study is conducted according to 
sound medical practices, following local regulatory compliance, and ICH-GCP. 
The Investigator will be responsible for ensuring that an annual update is sent to the IRB/IEC 
and/or appropriate local review board to facilitate their continuing review of the study (ICH E6 
ICH-GCP Sections 3 and 4.4) and that the IRB/IEC and/or appropriate local review board is 
informed about the end of the study. Copies of the update, subsequent approvals, and final letter

must be sent to the CRO. Copies of all correspondence (eg, letters, email) to and from the 
IRB/IEC and/or appropriate local review board must be kept on file at the site and be available 
for review by the Sponsor or Sponsor’s representative during monitoring visits or audits.  
10.5 Electronic Data Capture and Electronic Case Report Form 
An electronic case report form (eCRF) is required to be completed for each individual subject. 
The eCRFs will be provided for transfer of all research data by site personnel from data source 
documentation to a computer database. Each responsible person at a site, the CRO, or Sponsor 
will have user access with a unique username and password, with permissions providing each 
person their needed access. Some personnel will have data entry, data review, and query 
resolution permissions, while others may only have data read permissions, based on their 
individual study roles. 
Study monitors will verify computerized data against its source. Monitoring will be enhanced by 
computer-assisted data management identifying missing or possibly erroneous data as soon as 
data is entered into the EDC system. This approach will allow initial remote monitoring, and 
communication between study monitors and site personnel before and between site visits, and 
will expedite data review and cleaning. The flow of data from start to finish will be as follows: 
site personnel will enter subject data that meets all mandatory requirements per system edit 
checks, and will mark the data as complete, at which time the data will only be changeable via a 
query issued by the study monitor or data management group. Site personnel will respond to all 
queries. Study monitors will review, query and ultimately resolve those queries. The subject’s 
data will then be locked by data management, with only read access provided to authorized 
personnel. 
All study data are housed in a secure computing environment. The EDC system will include a 
complete audit trail of all data entry, monitoring, and query activity that is compliant with Health 
Insurance Portability and Accountability Act (HIPAA) and 21 CFR Part 11 requirements. 
Study data required by study monitors, other authorized representatives of the Sponsor, and 
appropriate regulatory authority inspectors will be available through the EDC system during the 
study. At the end of the study, a compact disc with site-specific data information will be 
provided to each site for archiving. 
All required study information must be entered into the EDC system. eCRFs are considered 
complete when all data fields are complete and acknowledged as correct by the Study Monitor. It 
is the Investigator’s responsibility to ensure completion, accuracy, review, and approval of all 
eCRFs. The Principal Investigator must sign an Investigator’s Statement at study completion for 
each subject to document that the Investigator has met these responsibilities. 
10.6 Modifications to the Protocol 
The procedures defined in the Protocol and eCRF will be carefully reviewed so that all parties 
involved with the study fully understand the Protocol. Only the Sponsor may initiate an 
amendment to the Protocol. Protocol amendments must be submitted and approved by the 
IRB/IEC prior to implementation.  
Protocol deviations affecting the safety of the subjects or the integrity of the data and must be 
avoided. However, deviations from the Protocol may be made if necessary to eliminate apparent

immediate hazard(s) to a subject or subjects. In this instance, the Investigator must notify the 
CRO and the IRB/IEC immediately after the deviation. The Sponsor will evaluate the 
circumstance and determine if the issue is broad enough to warrant a Protocol Amendment. 
Other deviations from the protocol must be submitted by Investigator to the IRB/IEC per their 
reporting requirements. A missed telephone call at two weeks (14 days ±2 days) after each 
administration will be considered a minor protocol deviation and will not remove a subject from 
the PP population.  
10.7 Maintenance and Retention of Records 
The study will be conducted in compliance with ICH-GCP. Investigators will follow the 
procedures of 21 CFR 312.62 and ICH E6, “Good Clinical Practice: Consolidated Guideline”, 
for retention of study records and data. It is the responsibility of the Investigator to maintain a 
comprehensive and centralized filing system of all relevant documentation. 
Investigators will be instructed to retain all study records required by the Sponsor, in a secure 
and safe facility with limited access. Records are to be retained for at least 2 years after approval 
of the application or withdrawal of the application unless otherwise notified by the Sponsor. 
Study documents should be retained for a longer period if required by local regulatory 
requirements. If the Investigator retires, relocates, or withdraws from this responsibility, custody 
may be transferred to a person who will accept this responsibility. The Sponsor must be notified 
in writing of the name of the new custodian. 
The records to be archived include all documents pertaining to subject information (eg, IRB/IEC 
correspondence, ICF, and HIPAA authorization form), receipt and return or destruction of 
Investigational Product, final signed eCRF casebooks including a copy of the audit trail, and 
correspondence with the CRO. No documents shall be destroyed without first notifying the 
Sponsor, and receiving confirmation of the notification by the Sponsor, at least 30 days prior to 
the planned date of destruction. 
10.8 Audits and Inspections 
During the course of the study and/or after it has been completed, one or more site audits may be 
conducted by authorized representatives of TOLMAR. The purpose of the audit would be to 
determine whether or not the study is being conducted and monitored in compliance with 
recognized ICH-GCP guidelines and regulations. 
Additionally, the study may be inspected by regulatory agencies. These inspections may take 
place at any time during the study or after completion of the study and are based on the local 
regulations. 
10.9 Completion of the Study 
The Principal Investigator for each participating site must submit a final report to TOLMAR and 
IRB/IEC within 12 months of study completion or termination.

13.2 Tanner Stages 
The Tanner stages, developed by Marshall and Tanner (1969) is a commonly used system to 
categorize pubertal maturation in terms of sequence, timing and tempo as described below. 
Boys - development of external genitalia 
Stage 1: 
Prepubertal 
Stage 2: 
Enlargement of scrotum and testes; scrotum skin reddens and changes in texture 
Stage 3: 
Enlargement of penis (length at first); further growth of testes 
Stage 4: 
Increased size of penis with growth in breadth and development of glans; testes 
and scrotum larger, scrotum skin darker 
Stage 5: 
Adult genitalia 
Girls - breast development 
Stage 1: 
Prepubertal 
Stage 2: 
Breast bud stage with elevation of breast and papilla; enlargement of areola 
Stage 3: 
Further enlargement of breast and areola; no separation of their contour 
Stage 4: 
Areola and papilla form a secondary mound above level of breast 
Stage 5: 
Mature stage: projection of papilla only, related to recession of areola 
Boys and girls - pubic hair 
Stage 1: 
Prepubertal (can see velus hair similar to abdominal wall) 
Stage 2: 
Sparse growth of long, slightly pigmented hair, straight or curled, at base of penis 
or along labia 
Stage 3: 
Darker, coarser and more curled hair, spreading sparsely over junction of pubes 
Stage 4: 
Hair adult in type, but covering smaller area than in adult; no spread to medial 
surface of thighs 
Stage 5: 
Adult in type and quantity, with horizontal distribution ("feminine")
