descent.

To assess the safety and tolerability of single SC doses of 25µg, 50µg, and 100µg of rhPTH(1-84) 
in healthy adult volunteer subjects of Japanese descent.

To evaluate the safety and tolerability of a single 100µg SC injection of rhPTH(1-84) in matched, 
non-Hispanic, healthy, adult volunteer Caucasian  subjects.
Rationale:
This study is being conducted to evaluate the PK, PD, safety and tolerability of rhPTH(1-84) after single-dose SC 
administration in adult healthy volunteers of Japanese descent in comparison with adult, healthy, non-Hispanic, 
Caucasian volunteers. In addition, this study will assess the PK dose-proportionality and similarity of rhPTH(1-84) 
in  healthy volunteers of Japanese descent as compared with historical data obtained in  non-Japanese healthy 
volunteers.
The Japanese regulatory agencies, Pharmaceuticals Medical Devices Agency (PMDA) and the Ministry of Health, 
Labor and Welfare (MHLW) require evidence that current data in non-Japanese subjects can be extrapolated to the 
Japanese population.
This study can be conducted in a facility that is located outside of the country of Japan as long as steps are taken to 
ensure that the subjects will be viewed as Japanese (or of direct Japanese descent).
The results from this study will be utilized to guide dose selection for a future Phase 3 study in Japanese patients 
with hypoparathyroidism.
Investigational product, dose, and mode of administration: The investigational product (rhPTH[1-84]) is a 
lyophilized powder form of recombinant human parathyroid hormone produced from genetically modified 
Escherichia coli and contained within a glass cartridge that includes sterile diluent as well. The investigational 
product is reconstituted within the glass cartridge and administered from an injector pen (Haselmeier) as a SC 
injection at doses of 25µg, 50µg and 100µg into the mid-thigh (100µg only in non-Hispanic, Caucasian subjects). 
The volume of reconstituted drug administered at 1 dose is 71.4µL.This study is open-label and does not require the 
use of a placebo.
Methodology:
This is a Phase 1, open-label, randomized, cross-over, single-center study to evaluate the PK and PD profiles and 
safety and tolerability of rhPTH(1-84) administered in healthy adult volunteer subjects of Japanese descent and 
matched non-Hispanic, Caucasian healthy adult volunteer subjects. The non-Hispanic, Caucasian volunteers will 
receive a single dose of 100µg rhPTH(1-84). The Japanese subjects will receive 3 single doses of rhPTH(1-84). On 
Day 1 the subjects of Japanese descent will receive a single SC injection of 100µg. On Days 4 and 7 the subjects of 
Japanese descent will be randomized to receive a single SC injection of either 25µg or 50µg. such that all of these 
subjects are exposed to the 3 dose strengths over a 7 day period to further characterize the PK profile in that group. 
A total of 24 subjects will be enrolled: 12 non-Hispanic, Caucasian subjects and 12 subjects of Japanese descent (1:1 
male: female). Non-Hispanic, Caucasian subjects will be matched to Japanese subjects based on sex, age (5 years), 
weight (10%), and body mass index (15%). 
All subjects will receive a single dose of 100μg rhPTH(1-84) administered by SC injection in the mid-thigh with the 
Haselmeier injector pen on Day 1. In addition, the subjects of Japanese descent will also receive single dose 
injections of 25µg and 50µg rhPTH(1-84) administered by SC injection in the mid-thigh to characterize the PK 
profile over a range of doses. There will be a minimum of 72 hours (maximum 73 hours) washout from single dose 
to single dose for the volunteers of Japanese descent. The study duration will comprise of a 28-day screening period, 
1 treatment period for the non-Hispanic, Caucasian group (Days 1 and 2); 1 treatment period for the volunteers of 
Japanese descent (Days 1-8), and a follow-up visit (30±2 days) after the last dose of investigation drug is 
administered for each subject. The total number of nights subjects will be expected to stay at the clinical research 
center (CRC) is 2 for the non-Hispanic, Caucasian group and 8 for the volunteers of Japanese descent. The maximal 
total duration of study participation for a non-Hispanic, Caucasian subject is 62 days and 68 days for the volunteers 
of Japanese descent, if the maximum screening, treatment and follow-up visit durations are used.
Screening will occur within 28 days of the first dose. Subjects will be admitted to the CRC on Day -1.

Treatment Periods:

On Day 1, all study subjects will receive rhPTH(1-84) as a single 100μg SC injection in the mid-thigh.

On Day 4, and Day 7, all subjects of Japanese descent will receive rhPTH(1-84) as a single SC injection in 
the mid-thigh of either 25µg or 50µg depending upon randomization assignment. Administration of 
rhPTH(1-84) in subjects of Japanese descent in the mid-thigh should be randomized locally so that an equal 
number of subjects receive the first dose in the right thigh and an equal number in the left thigh. 
Subsequent doses should be administered in the opposing thigh to the last dose.
Assessments

Serial blood samples for PK analysis will be collected on Day 1 (and Day 4 and Day 7 for the 
subjects of Japanese descent) for the determination of parathyroid hormone (PTH) concentrations 
(original and baseline-adjusted) at pre-dose and up to 24 hours post dose. These blood samples 
will be collected according to the Schedule of Assessments.

Serial blood samples for PD analysis will be collected on Day 1 (and Day 4 and Day 7 for the 
subjects of Japanese descent) at pre-dose and up to 24 hours post dose for the determination of 
serum calcium, phosphate, and albumin concentrations.

Safety and tolerability will be determined through assessment of treatment-emergent adverse 
events (TEAEs) and vital signs, electrocardiogram (ECG) findings, and clinical laboratory 
evaluations on Day 1 pre-dose and up to 24 hours post dose for the non-Hispanic, Caucasian 
subjects and Day 1 pre-dose and up to 24 hours post last dose (Day 8) for the subjects of Japanese 
descent.

Additional blood samples for safety purposes will be collected for assessment of anti-PTH 
antibodies.

Pharmacokinetic parameters will be calculated from original and baseline-adjusted plasma concentration-time data 
using non-compartmental methods and all calculations will be based on actual sampling times. Baseline is defined as 
the average Day 1 pre-dose concentration for all subjects (and the Day 4 and Day 7 average pre-dose concentration 
for the subjects of Japanese descent for those respective dosing intervals). PK parameters will be estimated based on 
non-compartmental analysis and will include, but not be limited to, the following:

Cmax:
Maximum concentration occurring at tmax

tmax:
Time of maximum observed concentration sampled during a dosing interval

AUClast:
Area under the curve from the time of dosing to the last measurable concentration

z:
First order rate constant associated with the terminal (log linear) portion of the curve

t½:
Terminal half-life

CL/F:
Apparent clearance

Vdz/F:
Apparent volume of distribution
Non-body weight adjusted and body weight-adjusted AUClast, Cmax, CL/F, and Vdz/F will be estimated. In addition, 
dose-normalized baseline-adjusted AUClast and Cmax will be calculated. 
Statistical Methodology for Pharmacokinetic Endpoint(s):
Individual concentrations (original and baseline-adjusted) and PK parameters (original, baseline-adjusted, body 
weight-adjusted, and dose-normalized-baseline-adjusted) of rhPTH(1-84) will be listed and summarized with 
descriptive statistics (number, arithmetic mean, standard deviation [SD], coefficient of variation [CV%], median, 
minimum, maximum, geometric mean, and %CV of geometric mean. The 95% confidence intervals of the geometric 
means of PK parameters will be presented as well. Figures of individual and mean (±SD) concentration-time profiles 
of the original and baseline-adjusted plasma rhPTH(1-84) will be generated on linear and semi-log scales. The mean 
plots will be generated by overlaying the Japanese cohort and Non-Japanese cohort. Figures of baseline-adjusted PK 
parameters and dose-normalized baseline-adjusted PK parameters vs dose in Japanese subjects will be generated. 
Box-Whisker plots for selected PK parameter will be generated with Japanese cohort and Non-Japanese side by side. 
Forest plots of geometric mean ratios for selected PK parameters between Japanese cohort vs Non-Japanese cohort 
will be generated.
Dose proportionality of PK parameters will also be examined for the Japanese subjects. Dose proportionality will be 
assessed for Cmax and AUC (AUC0-last) using the power model. The power model assumes a linear relationship 
between the natural log transformed parameter and the natural log transformed dose.
ln (Parameter) = α + β × ln (Dose) + Random error
Where α is the intercept, β is the slope, and Random error is a random residual error. Dose proportionality implies 
that slope = 1 and will be assessed by estimating mean slope with the corresponding two sided 90% confidence 
interval (CI) from the power model.
In order to compare the PKs of rhPTH(1-84) between subjects of Japanese descent and matched non-Hispanic, 
Caucasian subjects, the differences of log-transformed PK parameters from the rhPTH 100ug dose will be examined 
between groups using an analysis of variance model. The geometric mean ratio and its 90% confidence interval (CI) 
will be provided from the model. Baseline-adjusted PK parameters will be the primary PK endpoints, and other PK 
parameters will be the secondary PK endpoints. In addition, the difference of log-transformed dose-normalized 
baseline-adjusted AUClast and Cmax will be examined between the Japanese cohort estimated at the 50ug dose and 
the Non-Japanese cohort estimated at 100ug dose, as well as between the Japanese cohort estimated at the 25ug dose 
and the Non-Japanese cohort estimated at 100ug dose using an analysis of variance model. The geometric mean 
ratio and its 90% CI will be provided from the model.
Pharmacodynamic Endpoint(s):
Pharmacodynamic parameters will be computed from individual post dose values of serum calcium (uncorrected and

corrected for serum albumin levels and both unadjusted and baseline-adjusted) and phosphate using non-
compartmental methods. Pharmacodynamic parameters will be estimated based on both original and baseline-
adjusted values of serum calcium and phosphate. The calcium-phosphate product will be computed. Baseline is 
defined as the pre-dose value on Day 1 for all subjects and, additionally, also on Day 4 and Day 7 for the subjects of 
Japanese descent. All calculations will be based on actual sampling times. Pharmacodynamic parameters will be 
estimated based on non-compartmental analyses and will include, but not be limited to, the following:

AUClast: Area under the curve from the time of dosing to the last measurable concentration

tmax:
Time of maximum observed concentration sampled during a dosing interval

Emax:
Maximum effect

TEmax:
Time to maximum effect
Statistical Methodology for Pharmacodynamic Endpoint(s):
Individual values (original and baseline-adjusted) and PD parameters (original and baseline-adjusted) of serum total 
calcium, albumin-corrected calcium, phosphate and the calcium-phosphate (albumin-corrected calcium) product will 
be summarized with descriptive statistics (number, arithmetic mean, SD, CV%, median, minimum, maximum, 
geometric mean, and geometric CV%). Figures of individual and mean (±SD) concentration-time profiles of the 
original and baseline-adjusted PD markers, serum calcium (total and corrected for serum albumin) and phosphate, 
will be generated. Mean plots will be overlaid for the Japanese cohort and the Non-Japanese cohort. Box-Whisker 
plots for selected PD parameters will be prepared with the Japanese cohort and Non-Japanese cohort side by side.
Safety Endpoint(s):
Clinical laboratory tests, vital signs, and ECG findings will be summarized by treatment group and visit as indicated 
below:

Number, severity, seriousness and causality of treatment-emergent adverse events

Anti-PTH antibodies

Changes in vital signs, ECGs, and clinical laboratory results (hematology, chemistry, and 
urinalysis) from baseline to post baseline time points
Statistical Methodology for Safety Endpoint(s)
Safety data, including TEAEs, laboratory tests, anti-PTH antibodies, and vital signs, will be summarized. 
Descriptive statistics will be calculated for quantitative safety data as well as for the difference from baseline, if 
applicable. Frequency counts will be compiled for classification of qualitative safety data. Direct safety comparisons 
between the two ethnic groups will be presented from the rhPTH(1-84) 100µg dosing data. All other safety data 
from the 25µg and 50µg in the subjects of Japanese descent will be summarized and listed. Treatment-emergent AEs 
(TEAEs) are defined as AEs with start dates between the time of the first exposure to study drug and the last dose of 
the study drug.

BACKGROUND INFORMATION
Hypoparathyroidism is a rare disorder characterized by hypocalcemia in the presence of 
inappropriately low or undetectable levels of circulating parathyroid hormone (PTH) 
(Avioli 1974; Haussler and Cordy 1982; Shoback 2008). The most frequent cause of 
hypoparathyroidism is resection of, or damage to, parathyroid glands during neck surgery (eg, 
thyroidectomy), although multiple other genetic, metabolic and congenital etiologies exist. 
Hypoparathyroidism occurs in about 0.9% to 6.6% of thyroidectomies, with higher rates 
associated with more complicated interventions (Shoback 2008; Thomusch et al. 2003; Zarnegar 
et al. 2003; Page and Strunski 2007). In 1 year spanning 2007-2008 (Powers et al. 2013) the 
incidence of chronic hypoparathyroidism (≥6 months) was said to be approximately 60,000 
subjects in the United States, which rises to approximately 117,000 if the transient 
hypoparathyroid population is included (≤6 months). The same authors suggest that, of those 
117,000 transient hypoparathyroid subjects, about 5% will become chronic.
Parathyroid hormone is an 84-amino acid protein that is secreted by the parathyroid glands. PTH 
has a variety of important physiological functions that are outlined below to explain the effects 
of absent or deficient PTH levels. Parathyroid hormone functions to help regulate bone 
metabolism and serum levels of calcium and phosphate. In general, if serum calcium 
concentrations decrease, the parathyroid glands consequently increase PTH secretion, and, if 
serum calcium concentrations increase, the parathyroid glands consequently reduce PTH 
secretion. The parathyroid glands sense the level of extracellular calcium at the surface of the 
parathyroid cell and adjust the synthesis and secretion of PTH accordingly. The relationship 
between ionized extracellular calcium and PTH secretion is a steep sigmoidal curve where small 
variations in calcium level lead to significant changes in PTH secretion. Calcium sensing is 
initiated by the binding of calcium to a calcium sensing receptor (CaSR) that is present at high 
levels on the plasma membrane of the parathyroid cells. The CaSR, a member of the G-protein 
coupled receptor superfamily, is activated by calcium binding to it that, in turn, induces 
intracellular signals and, through largely unknown mechanisms, regulates the synthesis and 
secretion of PTH. The net physiological effects are an increase in circulating PTH levels when 
the extracellular calcium decreases and a decrease in PTH levels when the extracellular calcium 
increases (Bilezikian et al. 2011).
Acute symptoms of hypoparathyroidism, linked mainly to the hypocalcemia, are generally 
reversible. The key symptoms associated with hypocalcemia involve mainly the neuromuscular 
system: numbness, paresthesias, twitching, and tetany. More serious and potentially life 
threatening effects of hypocalcemia such as seizures, cardiac arrhythmias, cardiomyopathy and 
laryngeal spasm are also recognized in hypoparathyroidism (Behaghel and Donal 2011). Other 
symptomatology includes difficulty in concentrating described by many subjects as “brain fog” 
(Bilezikian et al. 2011). Hypoparathyroidism has also been linked to effects on mood and 
ideation (Arlt et al. 2002; Velasco et al. 1999).
The kidneys are especially vulnerable in subjects with hypoparathyroidism. Circulating PTH 
promotes renal calcium reabsorption, especially at the level of the distal convoluted tubule 
(Blaine et al. 2015). This additional fraction of calcium is instead excreted through the kidneys 
(Shoback 2008), leading to hypercalciuria which, together with a high-calcium-phosphate

product, can potentially can lead to nephrocalcinosis and kidney stones and, ultimately, to renal 
impairment (Blaine et al. 2015).

1.1
Indication and Current Treatment Options 
Prior to 2015, in the absence of an approved PTH replacement therapy, management of 
hypoparathyroidism consisted of supplemental oral calcium and active vitamin D in 
pharmacological doses sufficient to maintain the serum calcium level without the disabling 
symptoms of hypocalcemia. In order to improve the absorption of calcium from the 
gastrointestinal tract, pharmacological supplementation with active forms of vitamin D (eg, 
1,25-dihydroxyvitamin D3 [1,25(OH)2D3], calcitriol, 1,25-dihydroxycholecalciferol or α-calcidol 
[1(OH)D3]) is also required. Since PTH also functions in the kidney to stimulate the conversion 
of 25(OH)D3, the major circulating form of vitamin D, to the active vitamin D hormone 
(1,25[OH]2D3), the relative lack of circulating PTH results in a reduction of the production of 
active vitamin D. Thus, exogenous active vitamin D overcomes the synthetic block in 
endogenous production of the active vitamin D hormone in hypoparathyroidism. Together, 
supplemental oral calcium and active vitamin D have formed the mainstay of current treatment 
of subjects with hypoparathyroidism. As noted above, the additional calcium load that results 
from supplementation with exogenous calcium and active vitamin D contributes to the 
hypercalciuria and renal risks often noted in patients with hypoparathyroidism.
In an effort to limit the extent and effect of hypercalciuria, thiazide diuretics can be helpful since 
they promote renal calcium reabsorption. However, thiazides are associated with their own 
adverse events including hypokalemia and, more importantly, have no proven long-term effect to 
reduce hypercalciuria or kidney damage or improve the safety profile in this patient population 
(Shoback 2008). Although an accepted adjunct to the use of calcium and active vitamin D in 
hypoparathyroidism, thiazides are prescribed to only a minority of hypoparathyroid patients.
The investigational product (rhPTH[1-84]) is a recombinant human PTH that is identical in 
structure to endogenous human PTH, a single-chain polypeptide consisting of 84 amino acid 
residues and is manufactured using a strain of Escherichia coli modified by recombinant DNA 
technology. rhPTH(1-84) was approved for marketing in the United States on 23 January 2015 
under the brand name NATPARA® as a once-daily injectable dose as an adjunct to calcium and 
vitamin D to control hypocalcemia in patients with hypoparathyroidism.

Product Background
1.2.1
Preclinical Information
A total of 46 in vivo studies in mouse, rat, rabbit, dog, and rhesus and cynomolgus monkeys 
have evaluated the PKs, PDs and toxicology of rhPTH(1-84) at doses ranging from 0.1 to 10,000 
μg/kg given as single doses or as daily doses for up to 2 years. In the vast majority of studies, 
rhPTH(1-84) was administered by subcutaneous (SC) injection, the intended route of 
administration of rhPTH(1-84) in humans. A total of 7 in vitro pharmacology and toxicology 
studies have been performed.

In male and female rats, the administration of PTH was associated with an increase in the 
incidence of osteosarcoma. These data were interpreted as an increased risk for osteosarcoma in 
the clinic. Therefore, administration of rhPTH(1-84) should be avoided in subjects who are 
considered to be at increased risk for osteosarcoma (including those with Paget’s disease of bone 
or unexplained elevations of alkaline phosphatase, subjects with hereditary disorders 
predisposing to osteosarcoma or subjects with a history of prior external beam or implant 
radiation therapy involving the skeleton). Currently available results from animal reproductive 
toxicology studies suggest that rhPTH(1-84) is not associated with significant fetal or neonatal 
toxicity; however the safety of rhPTH(1-84) in pregnant or nursing women is not established.
For full details see the rhPTH(1-84) investigator brochure.
1.2.2
Clinical Information
Few studies of PTH use have been performed in the setting of hypoparathyroidism. Study 
CL1-11-040 (REPLACE) was a double-blind, placebo controlled study of once daily (QD) 
administration of 50μg to 100μg of rhPTH(1-84) which resulted in 54.8% of the rhPTH(1-84) 
subjects meeting a 3-tiered primary endpoint vs 2.5% of the placebo subjects (p<0.001). 
Long-term, open-label studies have supported these findings with subjects maintaining the 
physiologic benefit derived from rhPTH(1-84) treatment. One study, PAR-C10-008 (RACE), is 
ongoing with subjects receiving treatment for more than 5 years.
In clinical trials, rhPTH(1-84) significantly reduced the calcium-phosphate product. In these 
studies hypercalciuria was defined as an excretion of calcium in the urine greater than 300mg per 
24 hours. Data from the REPLACE Study and the long-term open label study, RACE, show that 
rhPTH(1-84) has a calcium-sparing effect, consistent with the reduction of calcium excretion 
seen in a previous PK/PD study (C09-002) of single dose administration of rhPTH(1-84) in 
patients with hypoparathyroidism in comparison with calcitriol administration.
The Phase 3 clinical study, REPLACE, was the largest, randomized, placebo controlled clinical 
study conducted in hypoparathyroidism population and was the pivotal study demonstrating that 
rhPTH(1-84) is effective in maintaining serum calcium levels and enabling significant decreases 
in active vitamin D and oral calcium doses. REPLACE also established the rhPTH(1-84) dose 
and dose titration and evaluated the physiologic effects of PTH replacement on serum calcium, 
serum phosphate, urinary calcium excretion and bone turnover markers. Eighty-four subjects 
were evaluated in the active treatment group and 40 subjects received placebo. Subjects received 
at a flexible dose range of 50 to 100μg SC in the thigh once daily for 6 months. The study met 
the primary efficacy triple endpoint, with a statistically higher responder rate (54.8%) versus 
placebo (2.5%). To meet the primary endpoint a subject had to fulfill all 3 conditions as follows: 
a 50% or greater reduction in oral calcium requirement, a 50% or greater reduction in active 
vitamin D therapy and an albumin corrected serum calcium (ACSC) concentration that was 
maintained within a range of 7.5 to 10.6 mg/dL.
A review of safety data across the hypoparathryodism program indicated that rhPTH(1-84) 
administered in the dose range of 25 to 100μg SC QD is safe for use for the treatment of 
hypoparathyroidism. Very common adverse reactions (ie, reported in at least 1 in every 10 
subjects) included hypocalcemia, hypercalcemia, headaches, diarrhea, vomiting, and

hypercalciuria. Common adverse reactions (ie, reported in at least 1 in every 100 subjects, but 
less than 1 in every 10 subjects) included hypomagnesemia, anxiety symptoms, palpitations, 
flushing, coughing and associated symptoms, neck pain, pollakiuria, chest pain, thirst, blood 
25-hydroxycholecalciferol decreased, and blood alkaline phosphatase increased.
There was no suggestion that rhPTH(1-84) causes drug-induced liver injury in humans. There 
were no renal-related adverse events (AEs) or abnormalities in renal function tests or urinalysis 
tests in clinical studies apart from changes expected from the mechanism of action of rhPTH(1-
84). Despite significant increases in total serum calcium levels and improved calcium 
homeostasis, treatment with rhPTH(1-84) did not result in worsening of hypercalciuria.
Potential risks include those effects which are extensions of the pharmacologic actions of PTH 
including hypercalcemia. Post-treatment hypocalcemia following the abrupt withdrawal of 
rhPTH(1-84) can be particularly problematic. Following sustained withdrawal of rhPTH(1-84), 
serum calcium levels must be carefully monitored with reinstatement of appropriate dosages of 
oral calcium and active vitamin D. No on-treatment events of hypocalcemia occurred following 
incidental missed doses of rhPTH(1-84) during any of the clinical studies; patients should be 
advised, however, to take their rhPTH(1-84) dose as soon possible following a missed dose and 
to take oral calcium.
The investigational product (rhPTH[1-84]) has been developed for the treatment of 
hypoparathyroidism. In the United States the drug is currently marketed under the brand name 
NATPARA as a once a day injectable treatment, indicated as an adjunct to calcium and vitamin D 
to control hypocalcemia in patients with hypoparathyroidism. However, because of the potential 
risk of osteosarcoma, NATPARA is recommended only for patients who cannot be well-controlled 
on calcium supplements and active forms of vitamin D alone.
Always refer to the latest version of the rhPTH(1-84) investigator’s brochure for the overall 
risk/benefit assessment and the most accurate and current information regarding the drug 
metabolism, PKs, efficacy, and safety of rhPTH(1-84).
1.3
Risk/Benefit and Ethical Assessment
There is no anticipated benefit from taking part in this study.
Risks for subject exposure to rhPTH(1-84) are listed in the current investigator brochure and 
include, but are not limited to, the following:

Osteosarcoma: In male and female rats, parathyroid hormone caused an increase in the 
incidence of osteosarcoma (a malignant bone tumor). The occurrence of osteosarcoma was 
dependent on parathyroid hormone dose and treatment duration. This effect was observed at 
parathyroid hormone exposure levels ranging from 3 to 71 times the exposure levels in 
humans receiving a 100μg dose of rhPTH(1-84). These data could not exclude a risk to 
humans. Because of a potential risk of osteosarcoma, it is recommended to use rhPTH(1-84) 
only in subjects with hypoparathyroidism who cannot be well-controlled on calcium and 
active forms of vitamin D alone and for whom the potential benefits are considered to

outweigh this potential risk. Use of rhPTH(1-84) is to be avoided in subjects who are at 
increased baseline risk for osteosarcoma such as subjects with Paget’s disease of bone or 
unexplained elevations of alkaline phosphatase, pediatric and young adult subjects with open 
epiphyses, subjects with hereditary disorders predisposing to osteosarcoma or subjects with a 
prior history of external beam or implant radiation therapy involving the skeleton.

Hypercalcemia during initiation of rhPTH(1-84) administration: In previous efficacy and 
safety studies in hypoparathyroidism, 29 of 121 (24.0%) rhPTH(1-84)-treated subjects 
experienced an on-treatment event of hypercalcemia. Monitoring of serum calcium during 
the treatment process can mitigate the risk, along with appropriate medical treatment.

Hypocalcemia with abrupt withdrawal of rhPTH(1-84) therapy: In previous efficacy and 
safety studies in hypoparathyroidism, 24 of 121 (19.8%) subjects experienced a post-
treatment event of hypocalcemia. Monitoring of serum calcium during the treatment process 
and after withdrawal can mitigate the risk, along with appropriate medical treatment.

The safety of rhPTH(1-84) in pregnant or nursing women has not been established. 
Pregnancy tests will be performed on all females on 2 occasions prior to entering the 
treatment phase of the study, and at discharge after treatment and at follow-up. Both men and 
women must agree to adequate contraception methods (see Section 4.4) before taking part in 
the study.

STUDY OBJECTIVES AND PURPOSE
2.1
Rationale for the Study
Recombinant human PTH (rhPTH[1-84]) is approved for use in the United States (US) as an 
adjunct to calcium and vitamin D to control hypocalcemia in patients with hypoparathyroidism. As a 
once-daily SC injection for hypoparathyroidism, it has been shown to provide a 24-hour 
sustained increase in serum calcium. Administration of rhPTH(1-84) resulted in dose-related 
increases in total serum calcium levels, with maximum mean increases (approximately 0.125 to 
0.175 mmol/L) observed 12 hours after dosing. Serum calcium levels did not return to baseline 
levels by 24 hours. This sustained increase may explain the reduction in the observed daily 
amounts of calcium and active vitamin D that were taken in the placebo-controlled trial.
Other clinical studies have reported experience with twice-daily use of a fragment of PTH 
(PTH[1-34]) injected SC in the setting of adult and pediatric subjects with hypoparathyroidism 
(Winer et al. 1998; Winer et al. 2003; Winer et al. 2008). In this setting, PTH(1-34) maintained 
eucalcemia and reduced urinary calcium excretion. In these studies, a comparison with calcitriol 
showed that either twice-daily PTH(1-34) or twice-daily calcitriol each maintained similar serum 
calcium levels, although urinary calcium excretion was lower in the PTH(1-34)-treated subjects.
Shire intends to develop rhPTH(1-84) for use in Japan. The Japanese regulatory agencies, 
Pharmaceuticals Medical Devices Agency (PMDA) and the Ministry of Health, Labor and 
Welfare (MHLW), require evidence that current data in non-Japanese subjects can be 
extrapolated to the Japanese population, since Japanese patients may require different doses of 
medication of some drug classes. 
To satisfy the PMDA and MHLW requirements, sponsors will provide data to support doses for 
a later study in Japanese subjects. The present study to compare PK and PD profiles and safety 
and tolerability in Japanese and (non-Hispanic) Non-Hispanic, Caucasian healthy volunteer 
subjects is designed for this reason. In addition, this study will also assess the PK dose-
proportionality of rhPTH(1-84) using three, randomized, single, SC doses of 25µg, 50µg and 
100µg in healthy volunteers of Japanese descent.

STUDY DESIGN
3.1
Study Design and Flow Chart
This is a Phase 1, open-label, randomized, cross-over, single-center study to evaluate the PK and 
PD profiles and safety and tolerability of rhPTH(1-84) administered in healthy adult volunteer 
subjects of Japanese descent and matched non-Hispanic, Caucasian healthy adult volunteer 
subjects. The non-Hispanic, Caucasian volunteers will receive a single dose of 100µg rhPTH(1-
84). The Japanese subjects will receive 3 single doses of rhPTH(1-84). On Day 1 the subjects of 
Japanese descent will receive a single SC injection of 100µg. On Days 4 and 7 the subjects of 
Japanese descent will be randomized to receive a single SC injection of either 25µg or 50µg. 
such that all of these subjects are exposed to the 3 dose strengths over a 7 day period to further 
characterize the PK profile in that group. A total of 24 subjects will be enrolled: 12 non-
Hispanic, Caucasian subjects and 12 subjects of Japanese descent (1:1 male: female). Non-
Hispanic, Caucasian subjects will be matched to Japanese subjects based on sex, age (±5 years), 
weight (±10%), and body mass index (±15%). 
All subjects will receive a single dose of 100μg rhPTH(1-84) administered by SC injection in the 
mid-thigh with the Haselmeier injector pen on Day 1. In addition, the subjects of Japanese 
descent will also receive single dose injections of 25µg and 50µg rhPTH(1-84) administered by 
SC injection in the mid-thigh to characterize the PK profile over a range of doses. There will be a 
minimum of 72 hours (maximum 73 hours washout from single dose to single dose for the 
volunteers of Japanese descent. The study duration will comprise of a 28-day screening period, 1 
treatment period for the non-Hispanic, Caucasian group (Days 1 and 2); 1 treatment period for 
the volunteers of Japanese descent (Days 1-8), and a follow-up visit (30±2 days) after the last 
dose of investigation drug is administered for each subject. The total number of nights subjects 
will be expected to stay at the clinical research center (CRC) is 2 for the non-Hispanic, 
Caucasian group and 8 for the volunteers of Japanese descent. The maximal total duration of 
study participation for a non-Hispanic, Caucasian subject is 62 days and 68 days for the 
volunteers of Japanese descent, if the maximum screening, treatment and follow-up visit 
durations are used.
Screening will occur within 28 days of the first dose. Subjects will be admitted to the CRC on 
Day -1.
Treatment Period:

On Day 1, all study subjects will receive rhPTH(1-84) as a single 100μg SC injection in the 
mid-thigh.

On Day 4, and Day 7, all subjects of Japanese descent will receive rhPTH(1-84) as a single 
SC injection in the mid-thigh of either 25µg or 50µg depending upon randomization 
assignment. Administration of rhPTH(1-84) in subjects of Japanese descent in the mid-thigh 
should be randomized locally so that an equal number of subjects receive the first dose in the 
right thigh and an equal number in the left thigh. Subsequent doses should be administered in 
the opposing thigh to the last dose.

Assessments

Serial blood samples for PK analysis will be collected on Day 1 (and Day 4 and Day 7 for the 
subjects of Japanese descent) for the determination of parathyroid hormone (PTH) 
concentrations (original and baseline-adjusted) at pre-dose and up to 24 hours post dose. 
These blood samples will be collected according to the Schedule of Assessments.

Serial blood samples for PD analysis will be collected on Day 1 (and Day 4 and Day 7 for the 
subjects of Japanese descent) at pre-dose and up to 24 hours post dose for the determination 
of serum calcium, phosphate, and albumin concentrations.

Safety and tolerability will be determined through assessment of treatment-emergent adverse 
events (TEAEs) and vital signs, electrocardiogram (ECG) findings, and clinical laboratory 
evaluations on Day 1 pre-dose and up to 24 hours post dose for the non-Hispanic, Caucasian 
subjects and Day 1 pre-dose and up to 24 hours post last dose (Day 8) for the subjects of 
Japanese descent.

Additional blood samples for safety purposes will be collected for assessment of anti-PTH 
antibodies.
Follow-up

A post treatment follow-up visit will be completed 30 (±2) days after the last dose of 
investigational product for each subject.

3.2
Rationale for Dose Selection and Study Design Elements
The primary objective of this study is to compare the PK profile of plasma rhPTH(1-84) between 
subjects of Japanese descent and non-Hispanic, Caucasian volunteers. Although endogenous 
PTH levels are different between healthy subjects and patients with hypoparathyroidism, 
historically, evaluations of different formulations, injection devices and dose proportionality, 
with PK as the primary objective, have been conducted in healthy subjects due to the distinct PK 
profile of plasma rhPTH(1-84) following subcutaneous administration compared to endogenous 
PTH. The PK profile of rhPTH(1-84) following subcutaneous administration had been shown to 
be similar between healthy subjects and patients with hypoparathyroidism in previous studies. 
Therefore, this study is to be conducted in healthy subjects. Due to the presence of endogenous 
PTH in healthy subjects and that the current PTH assay measures the total PTH concentration 
(combination of both endogenous PTH and rhPTH [the assay cannot distinguish between 
endogenous PTH and administered rhPTH(1-84)]), the PK analysis will be performed based on 
both the original and baseline-adjusted PTH concentrations. Due to the potential differences in 
body weight between enrolled subjects of Japanese descent and non-Hispanic, Caucasian 
subjects, in addition to the non-body weight adjusted PK parameters we will also use body 
weight-adjusted PK parameters for comparison.
rhPTH(1-84) (Natpara),  is currently approved in the US at doses of 25, 50, 75 and 100µg 
administered once daily. rhPTH(1-84) has demonstrated dose-proportional PKs over this dose 
range in studies performed in the western countries. No significant differences in either the PKs 
or PDs of  rhPTH(1-84) are anticipated between Japanese and non-Japanese; therefore, the 
100µg dose, the highest marketed dose, will be used in this study for direct comparative 
purposes. Further doses of 25µg and 50µg will be used in the subjects of Japanese descent to 
examine the dose proportionality of PKs in Japanese subjects 
Group comparison of the PK, PD, and safety of rhPTH(1-84) will be evaluated after a single 
dose administration in this study. Following subcutaneous administration of  rhPTH(1-84) at 
100µg, plasma PTH levels quickly increase and reach the first peak concentration 
(approximately 150pg/mL) at around 0.5 hour post dose, which is then followed by a second 
peak of a similar magnitude at 2-3 hours post dose. After the second peak, PTH levels decline 
quickly, with an estimated terminal half-life of about 1-2 hours. PTH levels return to baseline at 
about 12 hours post dose. Therefore there is no accumulation of plasma rhPTH after repeat 
dosing, and single dose treatment is considered sufficient to characterize the comparative PKs of 
rhPTH in this study at that dose. 
To examine the PK dose-proportionality of rhPTH(1-84) in the subjects of Japanese descent, 
Japanese subjects will receive single, SC doses of 25µg, 50µg, and 100µg rhPTH(1-84) and PK 
parameters will be evaluated for dose proportionality.

Duration and Study Completion Definition
The subject’s maximum duration of participation is expected to be approximately 62 days for the 
non-Hispanic, Caucasian volunteers and 68 days for the subjects of Japanese descent. The study

INVESTIGATIONAL PRODUCT
6.1
Identity of Investigational Product
The test product is rhPTH(1-84), which will be provided as a multiple dose, dual chamber, glass 
cartridge containing a sterile lyophilized powder and a sterile diluent for reconstitution at doses 
of 25µg, 50µg and 100µg.
The study drug cartridge (together with the study drug cartridge holder) is initially placed onto a 
mixing device to break the internal seal and allow the lyophilized powder and diluent to fully 
mix. Once mixed, the study drug and cartridge are placed into the Haselmeier injector pen in 
preparation for dosing.
Please note that in each administration of the drug by the pen injector (Haselmeier), a sterile, 
disposable pen needle is used and is specified as a Becton-Dickinson (BDTM) 0.25 mm x 8 mm 
(31G x 5/16”).
Additional information related to the investigational product, including preparation and 
administration, is provided in the current rhPTH(1-84) investigator brochure, and in an 
investigational product preparation and administration manual that will be provided.

Administration of Investigational Product(s)
6.2.1
Allocation of Subjects to Treatment
This is an open-label study.
Subject numbers are assigned to all subjects as they consent to take part in the study. Within each 
site (numbered uniquely within a protocol), the subject number is assigned to subjects according 
to the sequence of presentation for study participation. This will be a 4-digit number starting at 
0001.
For eligible subjects, the subject number will be the identifying number used throughout the 
CRF.
Once a subject number has been assigned, that number must not be used again if, for example, a 
subject is withdrawn from the study. If a subject number is allocated incorrectly, the clinical 
research associate/study monitor must be notified as soon as the error is discovered.
Investigational product packaging identification numbers, separate from subject numbers, may 
also be assigned to subjects for specific treatment assignment as dictated by the study. In these 
cases, the same investigational product packing identification number may not be assigned to 
more than 1 subject.

Shire
CONFIDENTIAL
Page 45
SHP634-102 Protocol
Natpara
29 Jan 2017
Each eligible subject will be assigned to 1 study drug cartridge (with a unique identifier). Each 
study drug cartridge should only be used for the subject to which it is assigned. Although each 
study drug cartridge holds multiple doses, only 1 dose from the cartridge must be used for the 
subject it is assigned to. Study drug cartridges and injector pens must be regarded as single use 
only and never used on more than 1 subject.
A study drug allocation scheme will be provided. The study drug allocation scheme must be 
maintained securely in the pharmacy.
6.2.2
Dosing
After each subject has completed the screening process and found to be eligible to proceed to 
dosing (inclusive of all clinical laboratory values), the subject will be assigned a study cartridge, 
mixing device and injector pen and, following preparation of the study drug, will be administered 
a single dose of investigational product in the mid-thigh on the morning of Day 1 (for all study 
subjects) and Days 4 and 7 (for subjects of Japanese descent only). A detailed pharmacy manual 
will be provided that describes the materials to be used, the preparation of materials and
administration of study drug.
6.2.3
Unblinding the Treatment Assignment
Not Applicable.
6.3
Labeling, Packaging, Storage, and Handling
6.3.1
Labeling
The study site will receive open label supplies of investigational product, injection pens and 
mixing devices required for dosing.
All clinical supplies will be manufactured, tested, labeled and released according to current legal 
and local country specific regulatory requirements and will comply with Good Manufacturing 
Practices.
Space is allocated on the label so that the site representative can record a unique subject 
identifier and initials.
Additional labels may, on a case-by-case basis, be applied to the investigational product in order 
to satisfy local or institutional requirements, but must not:

Contradict the clinical study label

Obscure the clinical study label

Identify the study subject by name
Additional labels may not be added without the sponsor’s prior full agreement.
In addition to labeling requirements for the investigative study drug, rhPTH(1-84), mixing 
devices and injector pens must also be labeled with the unique subject identifier. One mixing

device and 1 injector pen will be supplied for each subject taking part in the study for each dose. 
Mixing devices and injector pens must never be used between study subjects.
6.3.2
Packaging
Changes to sponsor-supplied packaging prior to dosing may not occur without full agreement in 
advance by the sponsor.
6.3.3
Storage
The investigator has overall responsibility for ensuring that investigational product is stored in a 
secure, limited-access location. Limited responsibility may be delegated to the pharmacy or 
member of the study team, but this delegation must be documented. Investigational products are 
distributed by the pharmacy or nominated member of the site study team. The 
pharmacist/nominated study team member will enter the unique subject identifier on the injector 
pen (containing the study drug cartridge) as they are distributed.
Investigational product must be stored in accordance with labeled storage conditions. 
Temperature monitoring is required at the storage location to ensure that the investigational 
product is maintained within an established temperature range. The investigator is responsible 
for ensuring that the temperature is monitored throughout the duration of the study and that 
records are maintained; the temperature should be monitored continuously by using either an 
in-house system, a mechanical recording device such as a calibrated chart recorder, or by manual 
means, such that both minimum and maximum thermometric values over a specific time period 
can be recorded and retrieved as required. Such a device (ie, certified min/max thermometer) 
would require manual resetting upon each recording. The sponsor must be notified immediately 
upon discovery of any excursion from the established range. Temperature excursions will require 
site investigation as to cause and remediation. The sponsor will determine the ultimate impact of 
excursions on the investigational product and will provide supportive documentation as 
necessary. Under no circumstances should the product be dispensed to subjects until the impact 
has been determined and the product is deemed appropriate for use by the sponsor.
The sponsor should be notified immediately if there are any changes to the storage area of the 
investigational product that could affect the integrity of the product(s), eg, fumigation of a 
storage room.
6.4
Drug Accountability
Investigators will be provided with sufficient amounts of the investigational product to carry out 
this protocol for the agreed-upon number of subjects. The investigator or designee will 
acknowledge receipt of the investigational product, documenting shipment content and 
condition. Accurate records of all investigational product dispensed, used, returned, and/or 
destroyed must be maintained as detailed further in this section.
The investigator has overall responsibility for administering/dispensing investigational product. 
Where permissible, tasks may be delegated to a qualified designee (eg, a pharmacist) who is 
adequately trained in the protocol and who works under the direct supervision of the investigator. 
This delegation must be documented in the applicable study delegation of authority form.

The investigator or his/her designee (as documented by the investigator in the applicable study 
delegation of authority form) will administer the investigational product only to subjects 
included in this study following the procedures set out in the study protocol. Each subject will be 
given only the investigational product carrying his/her treatment assignment. All administered 
investigational product will be documented on the source documents and/or other investigational 
product record.
No investigational product stock or returned inventory from a Shire-sponsored study may be 
removed from the site where originally shipped without prior knowledge and consent by the 
sponsor. If such transfer is authorized by the sponsor, all applicable local, state, and national 
laws must be adhered to for the transfer.
The sponsor or its representatives must be permitted access to review the supplies storage and 
distribution procedures and records.
At the end of the study, or as instructed by the sponsor, all unused stock, and empty/used 
investigational product packaging are to be sent to a nominated contractor on behalf of the 
sponsor. Investigational products being returned to the sponsor’s designated contractors must be 
counted and verified by clinical site personnel and the sponsor. For unused supplies where the 
original supplied tamper-evident feature is verified as intact, the tamper-evident feature must not 
be broken and the labeled amount is to be documented in lieu of counting. Shipment return 
forms, when used, must be signed prior to shipment from the site. Returned investigational 
products, if possible, must be packed in a tamper-evident manner to ensure product integrity. 
Contact the sponsor for authorization to return any investigational product prior to shipment. 
Shipment of all returned investigational product must comply with local, state, and national laws.
Based on entries in the site drug accountability forms, it must be possible to reconcile 
investigational products delivered with those used and returned. All investigational products 
must be accounted for and all discrepancies investigated and documented to the sponsor’s 
satisfaction.
6.5
Subject Compliance
The investigator/nominated person will record details on the drug accountability log(s) and/or 
source documents of study drug administration (including which thigh was used) and dosing 
details (time, date, dose level).

Safety
The name and address of each third party vendor (eg, clinical laboratory) used in this study will 
be maintained in the investigator’s and sponsor’s files.
Actual safety assessment times will be monitored and recorded. The sponsor’s expectation is that 
the investigator will ensure that every effort is made to perform all assessments at the precise 
protocol-scheduled time. Any safety assessment that deviates from the scheduled assessment 
time set forth in the protocol by more than ±15 minutes will be considered a protocol deviation 
(unless otherwise noted in the protocol).
Adverse events (defined as AEs occurring from the time of informed consent signature to the 
dose of investigational product), TEAEs (all AEs occurring after the treatment), prior medication 
and concomitant medication use will be assessed and monitored from the time the subject signs 
the informed consent form to completion of study (including to time of screen failure or drop 
out/discontinuation). While confined in the CRC, subject safety will also be closely monitored 
through BP measurements, ECG measurement, clinical safety labs and physician oversight.
In the event anti-PTH antibodies are detected following analysis for a subject, the investigator 
will be notified by the sponsor. It will be the investigator’s responsibility to notify the subject.
7.2.2.1
Medical and Medication History
A complete medical and medication history, as well as demographic information, will be 
performed at the screening visit/time points described in Table 1 by a qualified licensed 
physician, physician’s assistant, or a nurse practitioner. The medical history will be reviewed and 
recorded, including:

Recent ingestion of medication (30 days prior to entering the screening period)

History of respiratory, cardiovascular, renal, gastrointestinal, hepatic, endocrine, 
hematological, neurological, psychiatric, and other diseases
7.2.2.2
Physical Examination (Including Height and Weight)
A complete physical examination will be performed at the time points described in Table 1, 
Table 2, and Table 3 by a qualified licensed physician, physician’s assistant, or nurse 
practitioner.
The physical examination will include a review of the following body systems:

General appearance


Clinically significant abnormalities identified at the screening visit will be documented in the 
subject’s source documents. Changes after the screening visit will be captured as AEs on the AE 
source documentation, as deemed by the investigator.
7.2.2.3
Adverse Event Collection
At each study visit, subjects will be questioned in a general way to ascertain if AEs have 
occurred since the previous visit (eg, “Have you had any health problems since your last visit?”). 
Adverse events are collected from the time informed consent is signed. (Please refer to Section 8, 
Adverse and Serious Adverse Events Assessment.)
7.2.2.4
Vital Signs
BLOOD PRESSURE AND PULSE RATE
Blood pressure and pulse rate will be measured at times specified in Table 1, Table 2 and Table 3
of this protocol. Additional BP and pulse rate measurements may be performed, as determined 
by the investigator, in order to ensure appropriate monitoring of subject safety and accurate 
recording of vital sign measurements. Any changes from baseline which are deemed clinically 
significant by the investigator are to be recorded as an AE.
The same method for obtaining BP measurement (auscultatory or oscillometric) should be used 
throughout the study for all subjects (and documented). In addition, the conditions of vital sign 
measurements should be controlled and as consistent as possible during the study, in order to 
minimize external variability of the readings. It is advised that measurements be collected at a 
comfortable room temperature with little to no background noise, using the same (appropriately 
sized) cuff placed at the same location of the same arm during the study. The bladder deflation 
rate should be deflated (calibrated for oscillometric method or manually by auscultatory method) 
at a rate of 2-3 mmHg/s (and the first and last audible sounds recorded as systolic and diastolic 
pressure) after at least 5 minutes of rest in the assumed position.
The cuff should have a bladder length that is 80% and a width that is at least 40% of arm 
circumference (a length-to-width ratio of 2:1). 
The subject should be asked to remove all clothing that covers the location of cuff placement. 
The subject should not have exercised or consumed caffeine, alcohol, or nicotine within 30 
minutes of collection. The subject should be instructed to relax as much as possible for at least 5 
minutes prior to collection. The subject should remain quiet during this time and through the 
measurement.

Microscopic examination will be conducted if protein and/or blood is/are detected during 
urinalysis. At a minimum the microscopic examination will consist of red blood cells, white 
blood cells, casts, and bacteria. 
7.2.2.6
Pregnancy Test
A serum -hCG pregnancy test is required for all females at screening, on admission to the CRC 
on Day -1 and upon discharge from the CRC on Day 2 (for non-Hispanic, Caucasian subjects) or 
Day 8 (for subjects of Japanese descent) and at the final follow-up visit for all females. In 
addition, a pregnancy test is required if pregnancy is suspected or on early 
withdrawal/termination from the study.
7.2.2.7
Drug and Alcohol Screen
A urine screen for drugs of abuse and an alcohol breath test will be performed at the time points 
described in Table 1. Additional drug and alcohol screens may be performed at the investigator’s 
discretion.
Urine samples are to be tested for amphetamines, barbiturates, benzodiazepines, cannabinoids, 
cocaine, methadone, opiate metabolite, and phencyclidine.
Results of urine drug and alcohol screens will be reviewed and verified by the study monitor, but 
will not be collected in the CRF database.

Any positive result for drugs of abuse at screening or drugs of abuse and alcohol on Day -1 will 
exclude the subject from further participation in the study.
7.2.2.8
Serology Screen
At the screening visit, a blood sample of approximately 8.5mL will be drawn into a serum 
separator tube to test for the presence of HIV, HBsAg, and HCV antibody.
The test results must be confirmed negative prior to enrollment in the study. If a test result is 
positive, the subject will be excluded from entering the study. Results of the virology screen will 
be reviewed and verified by the study monitor, but will not be collected in the CRF database.
Positive serology results may be reported to the relevant health authorities by study site 
personnel if required by law.
7.2.2.9
Electrocardiogram
Twelve-lead ECGs will be performed at the times specified in Table 1, Table 2 and Table 3. All 
ECGs will be performed using the equipment supplied by the CRC.
The following parameters will be recorded in the source documentation: heart rate, time elapsed 
from P wave to R wave in an electrocardiogram (PR), the time between heart beats in an 
electrocardiogram (RR), measure of time for the 3 main deflections in an electrocardiogram 
(QRS), and QT intervals along with information on T and U wave morphology (T waves should 
be captured as normal/abnormal; U waves should be captured as absent/normal or abnormal). 
The measure of time between the start of the Q wave and the end of the T wave using Bazett’s 
formula in an electrocardiogram (QTcB) and QTcF will be derived from the data in the database. 
The investigator’s assessment of the ECG tracing as normal or abnormal must be documented, 
and if abnormal, his/her determination of whether the abnormality is clinically significant or not 
will be documented on the tracing and the source documentation (if different).
The subject should be asked to remove all clothing that covers the location of lead placement. 
The subject should not have exercised or consumed caffeine within 30 minutes prior to 
collection. The subject must be resting in the supine position for at least 5 minutes prior to 
collecting the ECG.
In some cases, it may be appropriate to repeat abnormal ECGs to rule out improper lead 
placement as contributing to the ECG abnormality. It is important that leads are placed in the 
same positions each time in order to achieve precise ECG recordings. 
Triplicate ECG recordings, including a 10-second rhythm strip, should be taken at each time 
point. They should be immediately assessed as valid recordings and if not valid, they should be 
repeated. Invalid recordings will not be entered included in the CRF database.
A triplicate ECG recording is to be performed at each time point approximately 2-4 minutes 
apart. The averages of the ECG triplicate collected predose on Day 1 (all subjects) and predose 
on Days 4 and 7 (subjects of Japanese descent) will serve as the subject’s baseline ECG.

To ensure safety of the subjects, a qualified individual at the investigator site will make 
comparisons to baseline measurements.
If the triplicate average QTcF interval (calculated online on site) is increased by >45 msec from 
the baseline or an absolute QTcF value is >500 msec for any scheduled ECG, then 2 additional 
ECGs will be collected, approximately 2-4 minutes apart, to confirm the original measurement. 
If either of the QTcF values from these repeated ECGs remains above the threshold value (>45 
msec from the baseline; or is >500 msec), then a single ECG must be repeated at least hourly 
until QTcF values from 2 successive ECGs fall below the threshold value that triggered the 
repeat measurement. When triplicate ECGs are collected, the mean of the triplicate 
measurements should be used to trigger the decision to collect follow-up ECGs.
If QTcF values remain above 500 msec (or >45 msec from the baseline) for >4 hours (or sooner 
at the discretion of the investigator) or QTcF intervals get progressively longer, the subject 
should undergo continuous ECG monitoring. A cardiologist should be consulted if QTcF 
intervals do not return to <500 msec (or to <45 msec above the baseline) after 8 hours of 
monitoring (or sooner at the discretion of the investigator).
If a machine-read QTcF value is prolonged, as defined above, repeat measurements may not be 
necessary if a qualified physician’s interpretation determines that the QTcF values are in the 
acceptable range.

ADVERSE AND SERIOUS ADVERSE EVENTS ASSESSMENT
8.1
Definition of Adverse Events, Period of Observation, Recording of Adverse Events
An AE is any untoward medical occurrence in a clinical investigation subject administered a 
pharmaceutical product and that 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 a medicinal 
(investigational) product, whether or not related to the medicinal (investigational) product
(International Conference on Harmonisation [ICH] Guidance E2A 1995).
All AEs are collected from the time the informed consent is signed until the defined follow-up 
period stated in Section 7.1.3. This includes events occurring during the screening phase of the 
study, regardless of whether or not investigational product is administered. Where possible, a 
diagnosis rather than a list of symptoms should be recorded. If a diagnosis has not been made, 
then each symptom should be listed individually. All AEs should be captured on the appropriate 
source documents. In addition to untoward AEs, unexpected benefits outside the investigational 
product indication should also be captured on the AE source documentation.
All AEs must be followed to closure (the subject’s health has returned to his/her baseline status 
or all variables have returned to normal), regardless of whether the subject is still participating in 
the study. Closure indicates that an outcome is reached, stabilization achieved (the investigator 
does not expect any further improvement or worsening of the event), or the event is otherwise 
explained. When appropriate, medical tests and examinations are performed so that resolution of 
event(s) can be documented.
8.1.1
Severity Categorization
The severity of AEs must be recorded during the course of the event including the start and stop 
dates for each change in severity. An event that changes in severity should be captured as a new 
event. Worsening of pretreatment events, after initiation of investigational product, must be 
recorded as new AEs (for example, if a subject experiences mild intermittent dyspepsia prior to 
dosing of investigational product, but the dyspepsia becomes severe and more frequent after first 
dose of investigational product has been administered, a new AE of severe dyspepsia [with the 
appropriate date of onset] is recorded in the source documentation).
The medical assessment of severity is determined by using the following definitions:
Mild:
A type of AE that is usually transient and may require only minimal treatment or 
therapeutic intervention. The event does not generally interfere with usual 
activities of daily living.
Moderate:
A type of AE that is usually alleviated with specific therapeutic intervention. The 
event interferes with usual activities of daily living, causing discomfort but poses 
no significant or permanent risk of harm to the research subject.

Shire
CONFIDENTIAL
Page 62
SHP634-102 Protocol
Natpara
29 Jan 2017
Severe:
A type of AE that interrupts usual activities of daily living, or significantly affects 
clinical status, or may require intensive therapeutic intervention.
8.1.2
Relationship Categorization
A physician/investigator must make the assessment of relationship to investigational product for 
each AE. The investigator should decide whether, in his or her medical judgment, there is a 
reasonable possibility that the event may have been caused by the investigational product. If 
there is no valid reason for suggesting a relationship, then the AE should be classified as “not 
related”. Otherwise, if there is any valid reason, even if undetermined or untested, for suspecting 
a possible cause-and-effect relationship between the investigational product and the occurrence 
of the AE, then the AE should be considered “related”. The causality assessment must be 
documented in the source document.
The following additional guidance may be helpful:
Term
Relationship Definition
Related
The temporal relationship between the event and the administration of the 
investigational product is compelling and/or follows a known or suspected response 
pattern to that product, and the event cannot be explained by the subject’s medical 
condition, other therapies, or accident.
Not Related
The event can be readily explained by other factors such as the subject’s underlying 
medical condition, concomitant therapy, or accident and no plausible temporal or 
biologic relationship exists between the investigational product and the event.
8.1.3
Outcome Categorization
The outcome of AEs must be recorded during the course of the study on the source 
documentation. Outcomes are as follows:

Fatal

Not Recovered/Not Resolved

Recovered/Resolved

Recovered/Resolved With Sequelae

Recovering/Resolving

Unknown
8.1.4
Clinical Laboratory and Other Safety Evaluations
A change in the value of a clinical laboratory, vital sign, or ECG assessment can represent an AE 
if the change is clinically relevant or if, during treatment with the investigational product, a shift 
of a parameter is observed from a normal value to an abnormal value, or a further worsening of 
an already abnormal value. When evaluating such changes, the extent of deviation from the 
reference range, the duration until return to the reference range, either while continuing treatment 

Shire
CONFIDENTIAL
Page 63
SHP634-102 Protocol
Natpara
29 Jan 2017
or after the end of treatment with the investigational product, and the range of variation of the 
respective parameter within its reference range, must be taken into consideration.
If, at the end of the treatment phase, there are abnormal clinical laboratory, vital sign, or ECG 
values which were not present at the pretreatment value observed closest to the start of study 
treatment, further investigations should be performed until the values return to within the 
reference range or until a plausible explanation (eg, concomitant disease) is found for the 
abnormal values.
The investigator should decide, based on the above criteria and the clinical condition of a 
subject, whether a change in a clinical laboratory, vital sign, or ECG parameter is clinically 
significant and therefore represents an AE.
8.1.5
Pregnancy
All pregnancies are to be reported from the time informed consent is signed until the defined 
follow-up period stated in Section 7.1.3.
Any report of pregnancy for any female study participant or the partner of a male study 
participant must be reported within 24 hours to the Shire Global Pharmacovigilance and Risk
Management Department using the Shire Investigational and Marketed Products Pregnancy 
Report Form. A copy of the Shire Investigational and Marketed Products Pregnancy Report 
Form (and any applicable follow-up reports) must also be sent to the contract research 
organization (CRO)/Shire medical monitor using the details specified in the emergency contact 
information section of the protocol. The pregnant female study participant must be withdrawn 
from the study.
Every effort should be made to gather information regarding the pregnancy outcome and 
condition of the infant. It is the responsibility of the investigator to obtain this information within 
30 calendar days after the initial notification and approximately 30 calendar days post partum.
Pregnancy complications such as spontaneous abortion/miscarriage or congenital abnormality 
are considered SAEs and must be reported using the Shire Clinical Study Serious Adverse Event 
and Non-serious AEs Required by the Protocol Form. Note: An elective abortion is not 
considered an SAE.
In addition to the above, if the investigator determines that the pregnancy meets serious criteria, 
it must be reported as an SAE using the Shire Clinical Study Serious Adverse Event and 
Non-serious AEs Required by the Protocol Form as well as the Shire Investigational and
Marketed Products Pregnancy Report Form. The test date of the first positive serum/urine -hCG 
test or ultrasound result will determine the pregnancy onset date.
8.1.6
Abuse, Misuse, Overdose, and Medication Error
Abuse, misuse, overdose, or medication error (as defined below) must be reported to the sponsor 
according to the SAE reporting procedure whether or not they result in an AE/SAE as described 
in Section 8.2. Note: The 24-hour reporting requirement for SAEs does not apply to reports of 
abuse, misuse, overdose, or medication errors unless these result in an SAE.

The categories below are not mutually exclusive; the event can meet more than 1 category.

Abuse – Persistent or sporadic intentional intake of investigational product when used for a 
nonmedical purpose (eg, to alter one’s state of consciousness or get high) in a manner that 
may be detrimental to the individual and/or society

Misuse – Intentional use of investigational product other than as directed or indicated at any 
dose (Note: this includes a situation where the investigational product is not used as directed 
at the dose prescribed by the protocol)

Overdose – Intentional or unintentional intake of a dose of investigational product higher 
than the protocol-prescribed dose

Medication Error – An error made in prescribing, dispensing, administration, and/or use of 
an investigational product. For studies, medication errors are reportable to the sponsor only 
as defined below.
Medication errors should be collected/reported for all products under investigation.
The administration and/or use of an expired investigational product should be considered as a 
reportable medication error.
The administration of rhPTH(1-84) to an eligible volunteer following an excursion in 
temperature requirements (outlined in the pharmacy manual), without assessment of the 
excursion and permission of the sponsor to proceed, is deemed a medication error.
It is not expected that overdose would occur in this protocol. The investigative product used in 
this study is supplied in 1 strength only, and is administered once only per volunteer, by a trained 
and responsible staff member at the study site with sponsor oversight.
8.2
Serious Adverse Event Procedures
8.2.1
Reference Safety Information
The reference for safety information for this study is the rhPTH(1-84) investigators brochure 
which the sponsor has provided under separate cover to all investigators.
8.2.2
Reporting Procedures
All initial and follow-up SAE reports must be reported by the investigator to the Shire Global 
Pharmacovigilance and Risk Management Department and the Shire medical monitor within 24 
hours of the first awareness of the event. Note: The 24-hour reporting requirement for SAEs does 
not apply to reports of abuse, misuse, overdose, or medication errors (see Section 8.1.6) unless 
they result in an SAE.
The investigator must complete, sign, and date the Shire Clinical Study Serious Adverse Event 
and Non-serious AEs Required by the Protocol Form and verify the accuracy of the information 
recorded on the form with the corresponding source documents (Note: Source documents are not 
to be sent unless requested) and fax or e-mail the form to the Shire Global Pharmacovigilance 
and Risk Management Department. A copy of the Shire Clinical Study Serious Adverse Event 
and Non-serious AEs Required by the Protocol Form (and any applicable follow-up reports)

contact information section of the protocol.
8.2.3
Serious Adverse Event Definition
A serious adverse event (SAE) is any untoward medical occurrence (whether considered to be 
related to investigational product or not) that at any dose:

Results in death

Is life-threatening. 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 was more severe.

Requires inpatient hospitalization or prolongation of existing hospitalization. Note: 
Hospitalizations that are the result of elective or previously scheduled surgery for 
pre-existing conditions and have not worsened after initiation of treatment should not be 
classified as SAEs. For example, an admission for a previously scheduled ventral hernia 
repair would not be classified as an SAE; however, complication(s) resulting from a 
hospitalization for an elective or previously scheduled surgery that meet(s) serious criteria 
must be reported as SAE(s).

Results in persistent or significant disability/incapacity

Is a congenital abnormality/birth defect

Is an important medical event. Note: Important medical events that may not result in death, 
be life-threatening, or require hospitalization may be considered an SAE when, based upon 
appropriate medical judgment, they may jeopardize the subject and may require medical or 
surgical intervention to prevent 1 of the outcomes listed in this definition. Examples of such 
medical events include allergic bronchospasm requiring intensive treatment in an emergency 
room or at home; blood dyscrasias or convulsions that do not result in inpatient 
hospitalization; or the development of drug dependency or drug abuse.
8.2.4
Serious Adverse Event Collection Time Frame
All SAEs (regardless of relationship to study) are collected from the time the subject signs the 
informed consent until the defined follow-up period stated in Section 7.1.3 and must be reported 
to the Shire Global Pharmacovigilance and Risk Management Department and the Shire medical 
monitor within 24 hours of the first awareness of the event.
In addition, any SAE(s) considered “related” to the investigational product and discovered by the 
investigator at any interval after the study has completed must be reported to the Shire Global 
Pharmacovigilance and Risk Management Department within 24 hours of the first awareness of 
the event.
8.2.5
Serious Adverse Event Onset and Resolution Dates
The onset date of the SAE is defined as the date the event meets serious criteria. The resolution 
date is the date the event no longer meets serious criteria, the date the symptoms resolve, or the 

Shire
CONFIDENTIAL

event is considered chronic. In the case of hospitalizations, the hospital admission and discharge 
dates are considered the onset and resolution dates, respectively.
In addition, any signs or symptoms experienced by the subject after signing the informed consent 
form, or leading up to the onset date of the SAE, or following the resolution date of the SAE,
must be recorded as an AE, if appropriate.
8.2.6
Fatal Outcome
Any SAE that results in the subject’s death (ie, the SAE was noted as the primary cause of death) 
must have fatal checked as an outcome with the date of death recorded as the resolution date. For 
all other events ongoing at the time of death that did not contribute to the subject’s death, the 
outcome should be considered not resolved, without a resolution date recorded.
For any SAE that results in the subject’s death or any ongoing events at the time of death, unless 
another investigational product action was previously taken (eg, drug interrupted, reduced, 
withdrawn), the action taken with the investigational product should be recorded as “dose not 
changed” or “not applicable” (if the subject never received investigational product). The 
investigational product action of withdrawn should not be selected solely as a result of the 
subject’s death.
8.2.7
Regulatory Agency, Institutional Review Board, Ethics Committee, and Site 
Reporting
The sponsor is responsible for notifying the relevant regulatory authorities and the US central 
Institutional Review Boards (IRBs) of related, unexpected SAEs.
In addition the sponsor is responsible for notifying active sites of all related, unexpected SAEs 
occurring during all interventional studies across the SHP634 clinical program. 
The investigator is responsible for notifying the local IRB, local ethics committee (EC), or the 
relevant local regulatory authority of all SAEs that occur at his or her site as required.

DATA MANAGEMENT AND STATISTICAL METHODS
9.1
Data Collection
The investigators’ authorized site personnel must enter the information required by the protocol 
from the source documentation to the CRF. A study monitor will visit each site in accordance 
with the monitoring plan and review the CRF data against the source data for completeness and 
accuracy. Discrepancies between source data and data entered on the CRF will be addressed by 
qualified site personnel. When a data discrepancy warrants correction, the correction will be 
made by authorized site personnel. Data collection procedures will be discussed with the site at 
the site initiation visit and/or at the investigator’s meeting. Once a subject is randomized, it is 
expected that site personnel will complete the CRF entry within a reasonable window of the 
subject’s visit.
9.2
Clinical Data Management
Data are to be entered into a clinical database as specified in the CRO’s data management plan. 
Quality control and data validation procedures are applied to ensure the validity and accuracy of 
the clinical database.
Data are to be reviewed and checked for omissions, errors, and values requiring further 
clarification using computerized and manual procedures. Data queries requiring clarification are 
to be communicated to the site for resolution. Only authorized personnel will make corrections to 
the clinical database, and all corrections are documented in an auditable manner.
9.3
Data Handling Considerations
This is an open label study and therefore there are no particular data handling concerns.
9.4
Statistical Analysis Process
The study will be analyzed by the sponsor or its agent.
The statistical analysis plan (SAP) will provide the statistical methods and definitions for the 
analysis of the PK, PD, and safety data, as well as describe the approaches to be taken for 
summarizing other study information such as subject disposition, demographics and baseline 
characteristics, investigational product exposure, and prior and concomitant medications. The 
SAP will also include a description of how missing, unused and spurious data will be addressed.
To preserve the integrity of the statistical analysis and study conclusions, the SAP will be 
finalized prior to database lock.
All statistical analyses will be performed using SAS(SAS Institute, Cary, NC 27513). 
9.5
Planned Interim Analysis, Adaptive Design, and Data Monitoring Committee
There is no planned interim analysis, adaptive design, or data monitoring committee (DMC) in 
this study.

Sample Size Calculation and Power Considerations
No formal calculations were performed to determine sample size for this study. The sample size 
is based on feasibility and is similar to that of comparable studies.
9.7
Study Population
The following study subject populations are defined for this study:

The safety population includes subjects who have received at least 1 dose of rhPTH(1-84).

The PK population consists of subjects who receive at least 1 dose of rhPTH(1-84) and have 
at least 1 evaluable post dose PK concentration value.

The PD population consists of subjects who receive at least 1 dose of rhPTH(1-84) and have 
at least 1 evaluable post dose PD concentration value.

Pharmacokinetic and Pharmacodynamic Analyses
9.8.1
Pharmacokinetic Analysis
All the PK analyses will be performed using the PK set.
A PK evaluation of PTH concentrations and baseline-adjusted PTH concentrations will be 
performed following the administration of rhPTH(1-84) administered on Day 1 for non-Hispanic, 
Caucasian subjects and Days 1, 4 and 7 for subjects of Japanese descent.
Pharmacokinetic parameters will be calculated from original and baseline-adjusted plasma 
concentration-time data using noncompartmental methods and all calculations will be based on 
actual sampling times. Baseline is defined as the average Day 1 predose concentration for all 
subjects (and the Day 4 and Day 7 average predose concentration for the subjects of Japanese 
descent for those respective dosing intervals). Pharmacokinetic parameters will be estimated 
based on noncompartmental analysis and will include, but not be limited to, the following:

Cmax: Maximum concentration occurring at tmax

tmax: Time of maximum observed concentration sampled during a dosing interval

AUClast: Area under the curve from the time of dosing to the last measurable concentration

z: First order rate constant associated with the terminal (log linear) portion of the curve

t½: Terminal half-life

CL/F: Apparent clearance

Vdz/F: Apparent volume of distribution
Non-body weight adjusted and body weight-adjusted AUClast, Cmax, CL/F, and Vdz/F will be 
estimated. In addition, dose-normalized baseline adjusted AUClast and Cmax will be calculated.

9.8.1.1
Statistical Analysis of Pharmacokinetic Parameters
Individual concentrations (original and baseline-adjusted) and PK parameters (original, baseline-
adjusted, body weight-adjusted, and dose-normalized-baseline-adjusted) of rhPTH(1-84) will be
listed and summarized with descriptive statistics (number, arithmetic mean, standard deviation 
[SD], coefficient of variation [CV%], median, minimum, maximum, geometric mean, and %CV 
of geometric mean. The 95% confidence intervals of the geometric means of PK parameters will 
be presented as well. Figures of individual and mean (±SD) concentration-time profiles of the 
original and baseline-adjusted plasma rhPTH(1-84) will be generated on linear and semi-log 
scales. The mean plots will be generated by overlaying the Japanese cohort and Non-Japanese 
cohort. Figures of baseline-adjusted PK parameters and dose-normalized baseline-adjusted PK 
parameters vs dose in Japanese subjects will be generated. Box-Whisker plots for selected PK 
parameter will be generated with Japanese cohort and Non-Japanese side by side. Forest plots of 
geometric mean ratios for selected PK parameters between Japanese cohort vs Non-Japanese 
cohort will be generated.
Dose proportionality of PK parameters will also be examined for the Japanese subjects. Dose 
proportionality will be assessed for Cmax and AUC (AUC0-last) using the power model. The 
power model assumes a linear relationship between the natural log transformed parameter and 
the natural log transformed dose.
ln (Parameter) = α + β × ln (Dose) + Random error
Where α is the intercept, β is the slope, and Random error is a random residual error. Dose 
proportionality implies that slope = 1 and will be assessed by estimating mean slope with the 
corresponding two sided 90% confidence interval (CI) from the power model.
In order to compare the PKs of rhPTH(1-84) between subjects of Japanese descent and matched 
non-Hispanic, Caucasian subjects, the differences of log-transformed PK parameters from the 
rhPTH 100ug dose will be examined between groups using an analysis of variance model. The 
geometric mean ratio and its 90% confidence interval (CI) will be provided from the model. 
Baseline-adjusted PK parameters will be the primary PK endpoints, and other PK parameters 
will be the secondary PK endpoints. In addition, the difference of log-transformed dose-
normalized baseline-adjusted AUClast and Cmax will be examined between the Japanese cohort 
estimated at the 50ug dose and the Non-Japanese cohort estimated at 100ug dose, as well as 
between the Japanese cohort estimated at the 25ug dose and the Non-Japanese cohort estimated 
at 100ug dose using an analysis of variance model. The geometric mean ratio and its 90% CI will 
be provided from the model.
9.8.2
Pharmacodynamic Analysis
All the PD analyses will be performed using the PD set.
Pharmacodynamic parameters will be computed from individual post dose values of serum 
calcium (uncorrected and corrected for serum albumin levels and both unadjusted and baseline-
adjusted) and phosphate using non-compartmental methods. Pharmacodynamic parameters will 
be estimated based on both original and baseline-adjusted values of serum calcium and 
phosphate. The calcium-phosphate product will be computed. Baseline is defined as the pre-dose

value on Day 1 for all subjects and, additionally, also on Day 4 and Day 7 for the subjects of 
Japanese descent. All calculations will be based on actual sampling times. Pharmacodynamic 
parameters will be estimated based on non-compartmental analyses and will include, but not be 
limited to, the following:

AUClast: Area under the curve from the time of dosing to the last measurable concentration

tmax: Time of maximum observed concentration sampled during a dosing interval

Emax: Maximum effect

TEmax: Time to maximum effect
9.8.3
Statistical Analysis of Pharmacodynamic Values
Individual values (original and baseline-adjusted) and PD parameters (original and baseline-
adjusted) of serum total calcium, albumin-corrected calcium, phosphate and the calcium-
phosphate (albumin-corrected calcium) product will be summarized with descriptive statistics 
(number, arithmetic mean, SD, CV%, median, minimum, maximum, geometric mean, and 
geometric CV%). Figures of individual and mean (±SD) concentration-time profiles of the 
original and baseline-adjusted PD markers, serum calcium (total and corrected for serum 
albumin) and phosphate, will be generated. Mean plots will be overlaid for the Japanese cohort 
and the Non-Japanese cohort. Box-Whisker plots for selected PD parameters will be prepared
with the Japanese cohort and Non-Japanese cohort side by side.
9.9
Safety Analyses
Adverse events will be coded using the Medical Dictionary for Regulatory Activities. The 
number of events, incidence, and percentage of treatment-emergent adverse events will be 
calculated overall, by system organ class, by preferred term, and by treatment group. 
Treatment-emergent adverse events will be further summarized by severity and relationship to 
investigational product. Adverse events related to investigational product, AEs leading to 
withdrawal, SAEs, and deaths will be similarly summarized/listed.
9.9.1
Safety Endpoint(s)
Clinical laboratory tests, vital signs, and ECG findings will be summarized by treatment group 
and visit as indicated below:

Number, severity, seriousness and causality of treatment-emergent adverse events

Anti-PTH antibodies

Changes in vital signs, ECGs, and clinical laboratory results (hematology, chemistry, and 
urinalysis) from baseline to post baseline time points
9.9.2
Statistical Methodology for Safety Endpoint(s)
Safety data, including TEAEs, laboratory tests, anti-PTH antibodies, and vital signs, will be 
summarized. Descriptive statistics will be calculated for quantitative safety data as well as for the 
difference from baseline, if applicable. Frequency counts will be compiled for classification of

Case report forms are supplied by the sponsor or sponsor representative and should be handled in 
accordance with instructions from the sponsor or sponsor representative.
The investigator is responsible for maintaining adequate and accurate medical records from 
which accurate information is recorded onto CRFs, which have been designed to record all 
observations and other data pertinent to the clinical investigation. Case report forms must be 
completed by the investigator or designee as stated in the site delegation log.
All data will have separate source documentation; no data will be recorded directly onto the 
CRF.
All data sent to the sponsor must be endorsed by the investigator.
The CRA/study monitor will verify the contents against the source data per the monitoring plan. 
If the data are unclear or contradictory, queries are sent for corrections or verification of data.
10.2.3.2 Recording, Access, and Retention of Source Data and Study Documents
Original source data to be reviewed during this study will include, but are not limited to the 
subject’s medical file and original clinical laboratory reports.
All key data must be recorded in the subject’s medical records.
The investigator must permit authorized representatives of the sponsor; the respective national, 
local, or foreign regulatory authorities; the IRB/EC; and auditors to inspect facilities and to have 
direct access to original source records relevant to this study, regardless of media.
The CRA/study monitor (and auditors, IRB/EC, or regulatory inspectors) may check the CRF 
entries against the source documents. The consent form includes a statement by which the 
subject agrees to the monitor/auditor from the sponsor or its representatives, national or local 
regulatory authorities, or IRB/EC, having access to source data (eg, subject’s medical file, 
appointment books, original laboratory reports, X-rays, etc.). 
These records must be made available within reasonable times for inspection and duplication, if 
required, by a properly authorized representative of any regulatory agency (eg, the US Food and

10.2.3.4 Financial Disclosure
The investigator is required to disclose any financial arrangement during the study and for 1 year 
after, whereby the outcome of the study could be influenced by the value of the compensation for 
conducting the study, or other payments the investigator received from the sponsor. The 
following information is collected: any significant payments from the sponsor or subsidiaries 
such as a grant to fund ongoing research, compensation in the form of equipment, retainer for 
ongoing consultation or honoraria; any proprietary interest in investigational product; any 
significant equity interest in the sponsor or subsidiaries as defined in 21 CFR 54 2(b) (1998).
10.3
Ethical Considerations
10.3.1
Informed Consent
It is the responsibility of the investigator to obtain written informed consent from all study 
subjects prior to any study-related procedures including screening assessments. All consent 
documentation must be in accordance with applicable regulations and GCP. Each subject or the 
subject’s legally authorized representative, as applicable, is requested to sign and date the subject 
informed consent form or a certified translation if applicable, after the subject has received and 
read (or been read) the written subject information and received an explanation of what the study 
involves, including but not limited to: the objectives, potential benefits and risk, inconveniences, 
and the subject’s rights and responsibilities. A copy of the informed consent documentation (ie, a 
complete set of subject information sheets and fully executed signature pages) must be given to 
the subject or the subject’s legally authorized representative, as applicable. This document may 
require translation into the local language. Signed consent forms must remain in each subject’s 
study file and must be available for verification at any time.
The principal investigator provides the sponsor with a copy of the consent form that was 
reviewed by the IRB/EC and received their favorable opinion/approval. A copy of the IRB/EC’s 
written favorable opinion/approval of these documents must be provided to the sponsor prior to 
the start of the study unless it is agreed to and documented (abiding by regulatory guidelines and 
national provisions) prior to study start that another party (ie, sponsor or coordinating principal 
investigator) is responsible for this action. Additionally, if the IRB/EC requires modification of 
the sample subject information and consent document provided by the sponsor, the 
documentation supporting this requirement must be provided to the sponsor.
10.3.2
Institutional Review Board or Ethics Committee
For sites outside the EU, it is the responsibility of the investigator to submit this protocol, the 
informed consent document (approved by the sponsor or their designee), relevant supporting

information and all types of subject recruitment information to the IRB/EC for review, and all 
must be approved prior to site initiation.
The applicant for an EC opinion can be the sponsor or investigator for sites within the EU; for 
multicenter studies, the applicant can be the coordinating principal investigator or sponsor, 
according to national provisions.
Responsibility for coordinating with IRBs/ECs is defined in the clinical trial agreement.
Prior to implementing changes in the study, the sponsor and the IRB/EC must approve any 
revisions of all informed consent documents and amendments to the protocol unless there is a 
subject safety issue.
Investigational product supplies will not be released until the sponsor has received written 
IRB/EC approval of and copies of revised documents.
For sites outside the EU, the investigator is responsible for keeping the IRB/EC apprised of the 
progress of the study and of any changes made to the protocol, but in any case at least once a 
year; for sites within the EU, this can be done by the sponsor or investigator, or, for multicenter 
studies, it can be done by the coordinating principal investigator, according to national 
provisions. The investigator must also keep the local IRB/EC informed of any serious and 
significant AEs.
10.4
Privacy and Confidentiality
All US-based sites and laboratories or entities providing support for this study, must, where 
applicable, comply with Health Insurance Portability and Accountability Act (HIPAA) of 1996. 
A site that is not a covered entity as defined by HIPAA must provide documentation of this fact 
to the sponsor.
The confidentiality of records that may be able to identify subjects will be protected in 
accordance with applicable laws, regulations, and guidelines.
After subjects have consented to take part in the study, the sponsor and/or its representatives’ 
reviews their medical records and data collected during the study. These records and data may, in 
addition, be reviewed by others including the following: independent auditors who validate the 
data on behalf of the sponsor; third parties with whom the sponsor may develop, register, or 
market rhPTH(1-84); national or local regulatory authorities; and the IRB/EC which gave 
approval for the study to proceed. The sponsor and/or its representatives accessing the records 
and data will take all reasonable precautions in accordance with applicable laws, regulations, and 
guidelines to maintain the confidentiality of subjects’ identities.
Subjects are assigned a unique identifying number; however, their initials and date of birth may 
also be collected and used to assist the sponsor to verify the accuracy of the data (eg, to confirm 
that laboratory results have been assigned to the correct subject).

The results of studies – containing subjects’ unique identifying number, relevant medical 
records, and possibly initials and dates of birth – will be recorded. They may be transferred to, 
and used in, other countries which may not afford the same level of protection that applies within 
the countries where this study is conducted. The purpose of any such transfer would include: to 
support regulatory submissions, to conduct new data analyses to publish or present the study 
results, or to answer questions asked by regulatory or health authorities.
10.5
Study Results/Publication Policy
Shire will endeavor to publish the results of all qualifying, applicable, and covered studies 
according to external guidelines in a timely manner regardless of whether the outcomes are 
perceived as positive, neutral, or negative. Additionally, Shire adheres to external guidelines (eg, 
Good Publication Practices 2) when forming a publication steering committee. The purpose of 
the publication steering committee is to act as a noncommercial body that advises or decides on 
dissemination of scientific study data in accordance with the scope of this policy.
All publications relating to Shire products or projects must undergo appropriate technical and 
intellectual property review, with Shire agreement to publish prior to release of information. The 
review is aimed at protecting the sponsor’s proprietary information existing either at the 
commencement of the study or generated during the study. To the extent permitted by the 
publisher and copyright law, the principal investigator will own (or share with other authors) the 
copyright on his/her publications. To the extent that the principal investigator has such sole, joint 
or shared rights, the principal investigator grants the sponsor a perpetual, irrevocable, 
royalty-free license to make and distribute copies of such publications.
The term “publication” refers to any public disclosure including original research articles, review 
articles, oral presentations, abstracts and posters at medical congresses, journal supplements, 
letters to the editor, invited lectures, opinion pieces, book chapters, electronic postings on 
medical/scientific websites, or other disclosure of the study results, in printed, electronic, oral or 
other form.
Subject to the terms of the paragraph below, the investigator shall have the right to publish the 
study results, and any background information provided by the sponsor that is necessary to 
include in any publication of study results, or necessary for other scholars to verify such study 
results. Notwithstanding the foregoing, no publication that incorporates the sponsor’s 
confidential information shall be submitted for publication without the sponsor’s prior written 
agreement to publish, and shall be given to the sponsor for review at least 60 days prior to 
submission for publication. If requested in writing by Shire, the institution and principal 
investigator shall withhold submission of such publication for up to an additional 60 days to 
allow for filing of a patent application.
If the study is part of a multicenter study, the first publication of the study results shall be made 
by the sponsor in conjunction with the sponsor’s presentation of a joint, multicenter publication 
of the compiled and analyzed study results. If such a multicenter publication is not submitted to a 
journal for publication by the sponsor within an 18-month period after conclusion, abandonment, 
or termination of the study at all sites, or after the sponsor confirms there shall be no multicenter

study publication of the study results, an investigator may individually publish the study results 
from the specific site in accordance with this section. The investigator must, however, 
acknowledge in the publication the limitations of the single-site data being presented.
Unless otherwise required by the journal in which the publication appears, or the forum in which 
it is made, authorship will comply with the International Committee of Medical Journal Editors 
(ICMJE) current standards. Participation as an investigator does not confer any rights to 
authorship of publications.
