Phase 2 
BACKGROUND AND SCIENTIFIC JUSTIFICATION FOR CONDUCTING THE TRIAL 
Nocturia is defined by the International Continence Society (ICS) as waking from sleep (during the 
night) at least once to urinate. This may occur when there is an excessive urine production during 
the night (nocturnal polyuria [NP]). The antidiuretic hormone arginine vasopressin (AVP) plays a 
key role in the control of urine production during the night. Desmopressin, a synthetic analogue of 
AVP developed by Ferring Pharmaceuticals, is approved and used for the treatment of nocturia due 
to NP in more than 80 countries, including Canada and European countries. However, 
desmopressin has not yet been approved for this indication in the USA.  
Low doses of desmopressin (25 µg for women and 50 µg for men) are approved to date in Canada, 
Australia and European countries under the trade name NOCDURNA (desmopressin Orally 
Disintegrating Tablet [ODT]). These gender specific minimum effective low doses are approved for 
use in all adult ages and are indicated for treatment of nocturia due to NP in adults, who awaken 
two or more times each night to void. The global cumulative patient exposure of NOCDURNA by 
end-2016 is 1,389 patient years based on a dose of 25 μg for women and 50 μg for men (women: 
779 patient years; men: 610 patient years). Analysis of the combined data from three trials of 
low-dose desmopressin ODT, comprising >1400 patients with nocturia, shows that desmopressin 
dose, patient age, baseline serum sodium levels, and kidney function according to estimated

glomerular filtration rate clearance were significant risk factors for hyponatraemia in both sexes. 
Ferring Pharmceuticals is currently developing FE 201836, another synthetic analogue of AVP and 
a potent and highly selective short-acting vasopressin-2 (V2)-receptor agonist with an antidiuretic 
action profile suitable for treating nocturia due to NP in adults. FE 201836 exerts its antidiuretic 
effect by increasing the water permeability of the luminal membrane of the renal cortical and 
medullary collecting ducts, and thereby reducing free water excretion. 
Hyponatraemia may develop over time if excessive drinking occurs during the period of 
antidiuretic drug effect. Therefore, the ideal V2-receptor agonist should provide an antidiuretic 
duration of action not exceeding 6-8 hours i.e., corresponding to the night-time sleep period when 
drinking does not occur or is limited to a minimum (to satisfy thirst). The oral half-life should be 
shorter than that of desmopressin and the key route of metabolism non-renal, since the clinical 
promise of a short-acting V2-receptor agonist is based on an improved safety profile without a 
prolonged duration of action leading to hyponatraemia. A shorter and more predictable duration of 
antidiuretic action would minimise the risk of hyponatraemia and may reduce the need for serum 
sodium monitoring. 
In the present clinical trial, 6 doses of FE 201836 (50-500 µg) will be evaluated for estimation of 
the dose-response curve, where the response is the change in the number of nocturnal voids. The 
choice of FE 201836 doses is based on the data regarding the antidiuretic effect of FE 201836 in 
healthy subjects and by the antidiuretic effects of desmopressin in healthy subjects and in patients 
with NP. 
In phase 1 trial 000195 in young healthy men and women oral doses of FE 201836 up to 4800 µg 
(i.e., 9.6 times higher than the suggested maximum dose in the present phase 2 trial) were 
administered and found to be safe and well tolerated. The exposure after intravenous infusion of 
0.5 µg FE 201836, comparable to the exposure after an oral dose of approximately 900 µg 
FE 201836, resulted in approximately 8 hours of antidiuretic effect.  
The present trial is powered for detecting differences in treatment effects between FE 201836 and 
placebo. Desmopressin is included as benchmark treatment. There is no prospectively planned 
power for conclusive inference with regards to differences between desmopressin and placebo (or 
FE 201836). 
In order to select trial subjects with nocturia primarily due to the underlying condition of NP driven 
with increased Free Water Clearance (FWC), who will benefit the most from treatment with an 
antidiuretic agent, a 1-week active run-in period followed by a 1-week washout period (referred to 
as the ‘enrichment period’) will be applied to ensure that drug-responders (defined as a reduction of 
nocturnal diuresis [mL/min]of 20% or more) are identified. The ≥20% decrease in the nocturnal 
diuresis rate has been established as a relevant marker of antidiurectic responsiveness in previous 
nocturia trials with an active run-in. The majority of fluid output occurs via the urine, 
approximately 1,500 mL/day, therefore there is no evidence in adult nocturia patients that the

relative change over the time in nocturnal diuresis rate (mL/min normalised to time in bed) should 
be adjusted for body weight and or/body surface area which are both assumed to be constant over a 
short period of just 1 week. An analysis of individual nocturia subject data found that reducing 
Nocturnal Urine Volume (NUV) and increasing the duration of antidiuretic action of a V2-receptor 
agonist (desmopressin) was a significant predictor for subsequent decrease from baseline in the 
number of nocturnal voids. 
The underlying pathophysiologic mechanism of NP can be driven by either increased FWC, which 
based on mode of action will be responsive to antidiuretic treatment, or by increased sodium 
clearance, which differs substantially in mode of action and is governed by Atrial Natriuretic 
Peptide (ANP) which again is directly and indirectly influenced by the Renin-Angiotensin-
Aldosterone System (RAAS).  
The aim of the active run-in is (after excluding all other medical causes of NP) to identify subjects 
with increased FWC which is responsive to V2-receptor agonism. In addition, safety will be 
assessed in this period with special emphasis on hyponatraemia.

METHODOLOGY 
This is a randomised, double-blind, placebo-controlled, response-adaptive, dose-finding trial 
investigating the efficacy, safety and tolerability of 6 different oral doses (50-500 µg) of 
FE 201836, with desmopressin as a benchmark, during 12 weeks of treatment for nocturia due to 
NP in adults. 
The trial will comprise 8 visits to the clinic and will consist of a 2-week screening/lifestyle changes 
period where no Investigational Medicinal Product (IMP) will be given, an enrichment period 
consisting of a 1-week single-blind (to subjects) active run-in period and a 1-week washout period, 
and a 12-week double-blind randomised treatment period for each subject. During the active run-in 
period the trial subjects will receive 500 µg FE 201836 and placebo to assess safety and establish 
that subjects who respond to treatment with FE 201836 are included in the trial (i.e., an enrichment 
design). 
The 12-week double-blind randomised treatment period of the trial will follow a response-adaptive 
Bayesian top-down design. Initially subjects will be randomised to: placebo, 500 µg FE 201836 or 
desmopressin (for benchmarking only). When approximately 125 subjects have been randomised to 
the trial, an interim analysis will be conducted to investigate the efficacy of 500 µg FE 201836. If 
500 µg FE 201836 is not sufficiently efficacious compared to placebo the trial will be stopped for 
futility. If 500 µg FE 201836 is efficacious additional doses of FE 201836 (doses 50-350 µg) will 
be opened up for randomisation of new subjects in order to identify the Minimum Effective Dose 
(MED) and near maximal Effective Dose (ED85). The ED85 is the lowest dose that achieves at least 
85% of the effect of the maximum dose (500 µg). After the first interim analysis, subsequent 
interim analyses will take place every 8 weeks to reassess the randomisation allocation probabilities 
to 50-500 µg FE 201836, based on observed responses at the respective interim locks. 
After the first interim analysis eligible subjects will be randomised to one of 8 treatment groups 
(Table S-1). Each subject will be instructed to take the IMP every night at bedtime with the 
intention to sleep. In order to keep the treatment blinded each subject will receive two medications 
throughout the trial; an oral solution and an Orally Disintegrating Tablet (ODT), i.e., a double-
dummy design will be applied because desmopressin is available in an ODT formulation and 
FE 201836 is an oral solution. 
Subjects will be asked to follow lifestyle changes (e.g., limiting fluid intake) throughout the entire

duration of the trial. In addition, subjects will be asked to complete electronic diary (e-Diary) 
assessments  and Patient Reported Outcome (PRO) questionnaires before and after randomisation. 
One objective of the present trial is to further validate the NI Diary. Therefore, a sample of subjects 
(from trial sites in the USA) who have completed the trial will be invited to participate in an exit 
interview within 14 days of attending the end-of-trial visit (Visit 8), to record the subjects’ 
perception of what constitutes a meaningful change in the NI Diary Total Score. 
Safety, including serum sodium levels, adverse events and clinically significant changes in vital 
signs and laboratory values will be monitored throughout the trial and reviewed on an ongoing 
basis by a Safety Review Committee (SRC). 
Furthermore, the risk for subjects developing hyponatraemia will be mitigated by a serum sodium 
monitoring plan, including a 1-week active run-in period to identify subjects at increased risk for 
developing acute hyponatraemia prior to randomisation. If the incidence of serum sodium levels 
<130 mmol/L is statistically significantly >10% during the active run-in, the Data Monitoring 
Committee (DMC) will be notified and further action will be discussed, e.g., the DMC may 
recommend that the highest dose of FE 201836 may be replaced by a lower dose. The trial is 
designed so the dose may be lowered from 500 µg to 350 µg, if recommended by the DMC. 
NUMBER OF SUBJECTS 
A maximum of 300 subjects (males and females) will be randomised into the trial. At least 50% of 
subjects should be randomised at trial sites in the USA.

DURATION OF TREATMENT 
The duration of the trial is approximately 16 weeks. Subjects will be screened, enter a 2-week 
lifestyle changes period followed by a 1-week single-blind active run-in and 1-week washout prior 
to randomisation. Following randomisation, the first 125 subjects will be treated daily with placebo, 
500 µg FE 201836 or desmopressin (25 µg for females and 50 µg for males) for up to 12 weeks. 
When the first 125 subjects have been randomised an interim analysis will be conducted and a 
decision taken on whether to continue the trial as planned or stop the trial for futility. 
If the decision is to continue the trial as planned, subjects may be randomised to one of 8 treatment 
groups for 12 weeks: placebo, 50 µg FE 201836, 100 µg FE 201836, 150 µg FE 201836, 250 µg FE 
201836, 350 µg FE 201836, 500 µg FE 201836, or desmopressin (25 µg for females and 50 µg for 
males). 
STATISTICAL METHODS 
Primary Analysis Model used in the Response-adaptive Trial Design 
The primary analysis is based on a time-course hierarchical longitudinal model, i.e., 
𝑌𝑡,𝑖= 𝑒𝛾𝑡(𝜇𝑑,𝑖+ 𝛿𝑖) + 𝜀𝑡 
where Yt,i is the change from baseline in number of nocturnal voids at visit t for subject i, d is the 
dose, 𝑒𝛾𝑡 the fraction of the effect at Visit t (Week 1, Week 4 or Week 8) as compared to the Month 
3 visit (𝛾t=0 at Month 3), δi the random subject effect and εt the independent N(0, 𝜆𝑡
2) distributed 
error term. The dose-response for subject 𝑖, 𝜇𝑑,𝑖, is adjusted for the number of baseline voids (𝑥0,𝑖) 
and modelled using the sigmoidal E-max model, i.e., 
𝜇𝑑,𝑖= 𝛽𝑥0,𝑖+ 𝛼1 +
(𝛼2 −𝛼1) 𝑑𝛼4
𝑑𝛼4 + 𝛼3𝛼4
= 𝛽𝑥0,𝑖+ 𝜇𝑑  
Inference will be based on a Bayesian analysis using sufficiently non-informative priors on 
respective parameters. The trial will be considered successful if the maximum dose has a greater 
than 97.5% posterior probability of being better than placebo, i.e., if Pr(μMAX < μPlb) > 97.5%.  
Response-adaptive Decision Rules 
The double-blind treatment period is based on a response-adaptive Bayesian top-down design. 
After an initial 125 subjects have been randomised to placebo, 500 µg FE 201836 (the highest dose) 
or desmopressin in a 2:2:1 ratio an interim analysis will take place to stop for futility if the Pr (μMAX 
– μPlb < -0.3) <10%, where Pr (.) denotes posterior probability (under the assumed monotonic dose-
response relation, i.e. smaller doses will be less effective). 
If not stopped for futility, all treatment arms will be opened up for randomisation, subjects can be 
randomised to placebo, desmopressin or to any FE 201836 dose (50-500 µg) in a 2:1:7 ratio. When 
allocated to a FE 201836 dose (7/10), unrestricted randomisation will be used to allocate a subject

to a specific FE 201836 dose using an allocation probability that is the average of I(dose is MED) 
and I(dose is ED85), where I(target) is the probability that “dose is target” scaled by the squared 
standard error at that dose. The MED is the lowest dose that has at least a ∆=0.3 larger reduction in 
mean nocturnal voids as compared to placebo and the ED85 is the lowest dose that achieves at least 
85% of the effect of the maximum dose (500 µg).  
After the first interim analysis, subsequent interims will take place every 8 weeks where the 
randomisation allocation probabilities to FE 201836 doses are being updated. Futility stopping will 
remain to take place if Pr (μMAX – μPlb < -0.3) <5.  
Operating Characteristics  
Under the assumptions (based on previous desmopressin trials and feasibility) that: 
• 
Response fractions of 0.8142, 0.9328 and 0.9874 at Weeks 1, 4 and 8, respectively, as 
compared to the averaged dose-response at Week 12 
• 
Variance fractions of 0.8481, 0.8329 and 0.8900 at Weeks 1, 4 and 8, respectively, as 
compared to the averaged dose-response at Week 12 
• 
A constant drop-out rate of 15% during the randomised treatment period 
• 
A between to total variance (σ2) ratio of 0.90 and a true underlying σ of 0.95 
• 
During the initial 17 weeks the recruitment rate will increase linearly from 0 to 8.2 subjects 
per week 
• 
After 17 weeks, when all trial sites have been initiated, the recruitment rate is assumed to 
remain constant at 8.2 subjects per week 
and  
• 
Considering six dose-response scenarios for the mean change from baseline to a large extent 
is characterised by the response of the maximum dose (500 µg FE 201836)

the power (probability of success) reaches approximately 85 to 90%, while the probability of 
making a false positive conclusion is 3.0%. 
Randomisation if the Maximum Dose is Lowered 
The trial has been designed with the option to decrease the maximum dose of FE 201836 from 
500 µg to 350 µg if recommended by the DMC. If this decision is made, randomisation to the 
500 µg FE 201836 treatment group will be closed, the trial will continue with 350 µg FE 201836 as 
the highest dose for the active run-in and the highest dose of FE 201836 that any subject can be 
randomised to. In the case where subjects have already been randomised to 500 µg FE 201836 and 
have not completed the trial the DMC will recommend whether or not, these subjects may be 
permitted to remain on 500 µg FE 201836 treatment for the remainder of the trial. In case subjects 
randomised to treatment with 500 µg FE 201836 prematurely discontinue the trial due to DMC 
decision they may be replaced by subjects randomised to treatment with a lower dose of 
FE 201836. No other prematurely discontinued subjects will be replaced. 
If the decision to close randomisation to 500 µg FE 201836 occurs prior to the first interim analysis 
(when the first 125 subjects are randomised) the remaining subjects will be randomised to the 
following treatment groups: placebo, desmopressin (25 µg for females and 50 µg for males) or 
350 µg FE 201836. After the first interim analysis the dose-response adaptive randomisation will 
allocate subjects to the remaining open doses, i.e., one of 7 treatment groups: placebo, 50 µg FE 
201836, 100 µg FE 201836, 150 µg FE 201836, 250 µg FE 201836, 350 µg FE 201836, or 
desmopressin (25 µg for females and 50 µg for males). 
The dose-response model will be fitted across all doses, i.e., 0-500 µg, but inference will be made 
only on the doses that remain open to randomisation e.g., 0-350 µg. That is, the MED and ED85 
doses and the inferences with regards to proof-of-concept and futility are limited to the dose range 
(i.e, with a maximum dose of 350 µg FE 201836).

Definition of Terms 
Hyponatraemia 
Hyponatraemia is categorised by severity based on serum sodium 
concentrations: 
• 
Normal lower limit of serum sodium >135 mmol/L 
• 
Mild hyponatraemia: serum sodium 134-130 mmol/L 
• 
Moderate* hyponatraemia: serum sodium <130 mmol/L 
• 
Severe hyponatraemia: serum sodium <125 mmol/L 
* Moderate hyponatraemia is equivalent to the term ‘clinically significant 
hyponatraemia‘ (Verbalis, 2013) 
Nocturnal diuresis 
The nocturnal diuresis rate is calculated from the mean of 3 days 
Nocturnal Urine Volume (NUV) and total time in bed: 
𝑁𝑜𝑐𝑡𝑢𝑟𝑛𝑎𝑙 𝑑𝑖𝑢𝑟𝑒𝑠𝑖𝑠 𝑟𝑎𝑡𝑒 (𝑚𝐿/𝑚𝑖𝑛) =
NUV (mL)
Total Time in Bed (min) 
 
FUSP 
First Undisturbed Sleep Period (FUSP) is defined as the time in minutes 
from the time of going to bed to the time of first nocturnal void, or time of 
awakening if no void occurred. 
MED 
The lowest dose that has at least a ∆=0.3 larger reduction in mean 
nocturnal voids as compared to placebo. 
ED85 
The lowest dose that achieves at least 85% of the effect of the maximum 
dose. 
NPi 
Nocturnal Polyuria index (NPi) is calculated by dividing the nocturnal 
urine volume (NUV) by the 24-hour urine volume (van Kerrebroeck, 
2002; Gormley, 2014). 
In this clinical trial the NPi definition >33% is used for all ages to define 
presence of Nocturnal Polyuria (NP). 
NUV 
Nocturnal Urine Volume (NUV) is the total urine volume from 5 minutes 
after bedtime with the intention to sleep until the first void within 
30 minutes of rising (in the morning). 
Enrichment 
period 
The enrichment period consists of 1 week active run-in followed by 
1 week washout. The enrichment ensures that subjects respond to the drug 
(reduction in nocturna diureis by ≥20% from Visit 2 to Visit 3) and have a 
stable condition of ≥2 voids at Visit 2 and Visit 4.

INTRODUCTION 
1.1 
Background 
Nocturia is defined by the International Continence Society (ICS) as waking from sleep (during the 
night) at least once to urinate. Nocturia is a symptom complex associated with several underlying 
medical and urological causes and pathologies (van Kerrebroeck, 2002; Wein, 2002). It is common 
in the elderly, occurring in up to 50% of men and women older than 75 years (Bosch, 2010). 
Nocturia is associated with a variety of clinical syndromes and disorders, which may result from 
(van Kerrebroeck, 2002): 
• 
Disorders that cause frequent low volume voids (e.g., Overactive Bladder [OAB], Bladder 
Outlet Obstruction [BOO], stiffer/less-compliant/functionally-smaller bladder associated 
with aging) 
or 
• 
frequent high volume voids (e.g., Nocturnal Polyuria [NP], global polyuria [diabetes 
insipidus or mellitus]) 
or 
• 
a combination of both, which is common. 
As described above, NP is a subset of nocturia defined as excessive volume of urine produced at 
night. The human body typically produces less urine while asleep. People with NP produce larger 
volumes of urine when asleep, causing them to awaken multiple times in the night to void. Thus, 
the diagnosis nocturia may be applied when there is an excessive urine production during the night. 
Nocturnal polyuria has been attributed to: 
• 
Abnormalities in diurnal variation in vasopressin secretion (a condition also coined as NP 
syndrome) (Asplund, 1991) 
• 
Abnormalities in the diuresis of solutes (e.g., urea, sodium, potassium) 
• 
Night time mobilisation of oedematous fluid in conditions such as congestive heart failure, 
nephrotic syndrome, or venous insufficiency 
However, as described above, patients often have more than one symptom presenting as nocturia 
(or NP); e.g., high volume of urine at night in combination with low volume bladder (perhaps 
associated with ageing) and BOO. 
Taken together, these facts make the clinical situation complicated since patients may have NP 
overlaid symptoms associated with frequent, low-volume voids, including OAB and Benign 
Prostatic Hyperplasia (BPH). 
The antidiuretic hormone arginine vasopressin (AVP) plays a key role in the control of urine 
production during the night. Desmopressin, a synthetic analogue of AVP developed by Ferring 
Pharmaceuticals, is approved and used for the treatment of nocturia due to NP in more than

80 countries, including Canada and European countries. However, desmopressin has not yet been 
approved for this indication in the USA. 
Low doses of desmopressin (25 µg for women and 50 µg for men) are approved to date in Canada, 
Australia and European countries under the trade name NOCDURNA (desmopressin Orally 
Disintegrating Tablet [ODT]). These gender specific minimum effective low doses are approved for 
use in all adult ages and are indicated for treatment of nocturia due to NP in adults, who awaken 
two or more times each night to void. The global cumulative patient exposure of NOCDURNA by 
end-2016 is 1,389 patient years based on a dose of 25 μg for women and 50 μg for men (women: 
779 patient years; men: 610 patient years). Analysis of the combined data from three trials of 
low-dose desmopressin ODT, comprising >1400 patients with nocturia, shows that desmopressin 
dose, patient age, baseline serum sodium levels, and kidney function according to estimated 
glomerular filtration rate clearance were significant risk factors for hyponatraemia in both sexes 
(Juul, 2016). 
Ferring Pharmaceuticals is currently developing FE 201836, another synthetic analogue of AVP 
and a potent and highly selective short-acting vasopressin-2 (V2)-receptor agonist with an 
antidiuretic action profile suitable for treating nocturia due to NP in adults. FE 201836 exerts its 
antidiuretic effect by increasing the water permeability of the luminal membrane of the renal 
cortical and medullary collecting ducts, and thereby reducing free water excretion. 
Hyponatraemia may develop over time if drinking occurs during the period of antidiuretic drug 
effect. Therefore, the ideal V2-receptor agonist should provide an antidiuretic duration of action not 
exceeding 6-8 hours i.e., corresponding to the night-time sleep period when drinking does not occur 
or is limited to a minimum (to satisfy thirst only). The oral half-life should be shorter than that of 
desmopressin and the key route of metabolism non-renal, since the clinical promise of a short-
acting V2-receptor agonist is based on an improved safety profile without a prolonged duration of 
action potentially leading to hyponatraemia. A shorter and more predictable duration of antidiuretic 
action would minimise the risk of hyponatraemia and may reduce the need for serum sodium 
monitoring. 
In the present clinical trial, 6 doses of FE 201836 (50-500 µg) will be evaluated for estimation of 
the dose-response curve, where the response is the change in the number of nocturnal voids. The 
selection of FE 201836 doses in the trial is based on data regarding the antidiuretic effect of 
FE 201836 in healthy subjects and by the antidiuretic effects of desmopressin in healthy subjects 
and in patients with NP. In a phase 1 trial (000195) in young healthy men and women, oral doses of 
FE 201836 of up to 4,800 µg were administered and found to be safe and well tolerated. The 
exposure after intravenous infusion of 0.5 µg FE 201836, comparable to the exposure after an oral 
dose of approximately 900 µg FE 201836, resulted in approximately 8 hours of antidiuretic effect. 
The present trial is powered for detecting differences in treatment effects between FE 201836 and 
placebo. Desmopressin is included as benchmark treatment. There is no prospectively planned 
power for conclusive inference with regards to differences between desmopressin and placebo (or 
FE 201836).

1.2 
Scientific Justification for Conducting the Trial 
Concern over hyponatraemia and the risk-benefit ratio has limited the use of desmopressin to 
younger patients and recently allowing treatment in elderly nocturia patients only under serum 
sodium monitoring. Renal impairment has also limited the use due to a risk of prolonging duration 
of action. FE 201836, a novel short-acting V2-receptor agonist, now under development, is 
designed to preserve potency at the V2-receptor at the same level as desmopressin, with a shorter 
half-life, increased selectivity, faster clearance and greater extra-renal clearance compared to 
desmopressin. 
The present phase 2 trial will establish the dose-response of FE 201836 with respect to the number 
of nocturnal voids in subjects with nocturia due to NP, allowing the development to proceed for a 
novel agonist at the V2-receptor for treatment of nocturia due to NP. 
1.3 
Benefit / Risk Aspects 
Benefits 
Subjects enrolled in the present trial will be closely monitored and they will have the same or more 
frequent visits to the hospital compared to routine treatment, depending on local practice. During 
these visits the subjects will be given instructions regarding lifestyle changes (including limiting 
fluid intake). For some subjects the implementation of lifestyle changes might be enough to reduce 
bothersome nocturia, defined as 2 or more nocturnal voids. 
Risks 
Treatment of nocturia due to NP with desmopressin implies a prolonged antidiuretic effect that may 
be associated with an increased risk of developing hyponatraemia, especially in elderly patients. 
FE 201836 is designed to preserve potency at the V2-receptor at the same level as desmopressin, 
with a shorter half-life, increased selectivity, faster clearance and greater extra-renal clearance 
compared to desmopressin. Based on the low degree of unchanged renal excretion of FE 201836, 
renal impairment is not expected to have any clinically relevant impact on the duration of the 
antidiuretic effect. 
An improved safety profile is expected to result from this combination of characteristics. The short 
half-life of FE 201836 (approximately 2 hours) and low degree of unchanged renal excretion 
(approximately 5%) are designed to limit the antidiuretic effect to the night-time sleep period, when 
subjects do not drink or their fluid intake is limited to a minimum (to satisfy thirst only). Therefore, 
the risk for dilutional hyponatraemia that may occur after the subject starts drinking in the morning 
is expected to be low. 
Subjects in the phase 1 clinical trial 000195 were dosed with up to 4800 µg (i.e., 9.6 times higher 
than the suggested maximum dose in the present phase 2 trial) orally without any subject being 
hyponatraemic. Pharmacokinetic/pharmacodynamic (PK/PD) modelling suggests that the duration 
of antidiuretic effect at 500 µg will be approximately 6 hours, limiting the potential for daytime 
antidiuresis.

In the present trial, the risk of subjects developing hyponatraemia will be mitigated by a serum 
sodium monitoring plan, as described in Section 7.1.3.1. The plan includes a 1-week active run-in 
period to identify subjects at increased risk for developing acute hyponatraemia prior to 
randomisation, as well as serum sodium sampling at Week 1, Week 4, Week 8 and Week 12, to 
identify any subject developing hyponatraemia while on treatment with Investigational Medicinal 
Product (IMP). Moreover, safety including the occurrence of adverse events and clinically 
significant changes in laboratory values (including serum sodium values) will be monitored 
throughout the trial.

3.1.2 
Overall Design and Control Methods 
This is a randomised, double-blind, placebo-controlled, response-adaptive, dose-finding trial 
investigating the efficacy, safety and tolerability of 6 different oral doses (50-500 µg) of 
FE 201836, with desmopressin as a benchmark, during 12 weeks of treatment for nocturia due to 
NP in adults. 
The trial will comprise 8 visits (Section 3.1.1) to the clinic and will consist of a 2-week 
screening/lifestyle changes period where no IMP will be given, an enrichment period consisting of 
a 1-week single-blind (to subjects) active run-in period and a 1-week washout period, and a 
12-week double-blind randomised treatment period for each subject (Figure 3-1). During the active 
run-in period the trial subjects will receive 500 µg FE 201836 and placebo to assess safety and 
establish that subjects who respond to treatment with FE 201836 are included in the trial (i.e., an 
enrichment design). 
The 12-week double-blind randomised treatment period of the trial will follow a response-adaptive 
Bayesian top-down design. Initially subjects will be randomised to: placebo, 500 µg FE 201836 or 
desmopressin (for benchmarking only). When approximately 125 subjects have been randomised to 
the trial, an interim analysis will be conducted to investigate the efficacy of 500 µg FE 201836. If 
500 µg FE 201836 is not sufficiently efficacious compared to placebo the trial will be stopped for 
futility. If 500 µg FE 201836 is efficacious additional doses of FE 201836 (doses 50-350 µg) will 
be opened up for randomisation of new subjects in order to identify the Minimum Effective Dose 
(MED) and near maximal Effective Dose (ED85). The ED85 is the lowest dose that achieves at least 
85% of the effect of the maximum dose (500 µg). After the first interim analysis, subsequent 
interim analyses will take place every 8 weeks to reassess the randomisation allocation probabilities 
to 50-500 µg FE 201836, based on observed responses at the respective interim locks. For more 
information regarding the interim analyses, please refer to Section 3.3 and Section 9.11.2. 
After the first interim analysis eligible subjects will be randomised to one of 8 treatment groups 
(Table 5-1). Each subject will be instructed to take the IMP every night at bedtime with the 
intention to sleep. In order to keep the treatment blinded each subject will receive two medications 
throughout the trial; an oral solution and an ODT, i.e., a double-dummy design will be applied 
because desmopressin is available in an ODT formulation and FE 201836 is an oral solution (Table 
5-1). 
Subjects will be asked to follow lifestyle changes (e.g., limiting fluid intake) throughout the entire 
duration of the trial. In addition, subjects will be asked to complete e-Diary assessments 
(Section 7.1.1) and PRO questionnaires (Section 7.1.1.3) before and after randomisation  
(Figure 3-2 and Figure 3-3). One objective of the present trial is to further validate the NI Diary. 
Therefore, a sample of subjects (from trial sites in the USA) who have completed the trial will be 
invited to participate in an exit interview within 14 days of attending the end-of-trial visit (Visit 8), 
to record the subjects’ perception of what constitutes a meaningful change in the NI Diary Total 
Score (Section 10.3.1).

Safety, including serum sodium levels (Section 7.1.3.1), adverse events and clinically significant 
changes in vital signs and laboratory values will be monitored throughout the trial and reviewed on 
an ongoing basis by a Safety Review Committee (SRC) (Section 3.4).  
Furthermore, the risk for subjects developing hyponatraemia will be mitigated by a serum sodium 
monitoring plan (Section 7.1.3.1), including a 1-week active run-in to identify subjects at increased 
risk for developing acute hyponatraemia prior to randomisation. If the incidence of serum sodium 
levels <130 mmol/L is statistically significantly >10% during the active run-in, the Data Monitoring 
Committee (DMC) established for the trial (Section 3.4) will be notified and further action will be 
discussed, e.g., the DMC may recommend that the highest dose of FE 201836 may be replaced by a 
lower dose. The trial is designed so the dose may be lowered from 500 µg to 350 µg if 
recommended by the DMC, as described in Section 9.11.1. 
3.1.3 
Trial Schedule 
The first trial visit (Visit 1, screening) for the first subject is expected in Q3 2017 and the last trial 
visit for the last subject is expected in Q3 2019. The total duration of the trial (for a subject) is 
expected to be approximately 18 weeks (including the exit interview). 
Trial completion is defined as when the last subject has completed the last visit in the randomised 
trial period (Visit 8). 
3.2 
Planned Number of Trial Sites and Subjects 
The trial will be conducted at approximately 70 sites in Europe and North America. A maximum of 
300 subjects will be included (Section 9.1). 
3.3 
Interim Analyses 
Interim analyses will be performed by an internal DMC established for the trial. 
The first interim analysis will be conducted after an initial 125 subjects have been randomised in a 
2:2:1 ratio to placebo, 500 µg FE 201836 or desmopressin. 
After the first 125 randomised subjects, the allocation ratio is 2:7:1 for placebo, active treatment 
and desmopressin, respectively. Subsequent interim analyses will be performed every 8 weeks, 
where the randomisation allocation probabilities to FE 201836 doses will be adjusted. 
The interim analyses are detailed in Section 9.11. 
3.4 
Safety Review and Data Monitoring Committees 
Trial data will be reviewed on an ongoing basis by the sponsor SRC. 
In addition, an internal DMC will be established for the trial. The main purpose of the DMC is to 
perform pre-planned interim analyses (Section 3.3) and make recommendations based on review of 
the efficacy and safety data. An additional purpose of the DMC is to address any potential safety 
concerns raised by the SRC. The responsibilities and the composition of the DMC are provided in a 
separate charter document.

3.5 
Discussion of Overall Trial Design and Choice of Control Groups 
3.5.1 
Trial Design 
The present clinical trial includes a 2-week period of lifestyle changes. Lifestyle changes (e.g., 
limiting fluid intake) are recommended as an initial treatment in most clinical guidelines, e.g., the 
updated American Urology Association (AUA) guideline on the management of BPH 
(McVary, 2011), despite the relative paucity of supporting data (Weiss, 2013). Excluding pelvic 
floor exercises for bladder-related Lower Urinary Tract Symptoms (LUTS), which are not part of 
the present trial, there seems to be no evidence that prolonged lifestyle changes, versus the 
proposed 2 weeks in the present trial, will result in additional benefit on NP related to excessive 
nocturnal fluid intake. From a practical point of view, the total of 4 weeks during the 
pre-randomisation period in the present trial is considered adequate for subject compliance. 
In order to select subjects with nocturia primarily due to the underlying condition of NP driven with 
increased Free Water Clearance (FWC), who will benefit the most from treatment with an 
antidiuretic agent, a 1-week active run-in period followed by a 1-week washout period will be 
applied to ensure that drug-responders (defined as subjects with a reduction of nocturnal diuresis 
rate [mL/min] of 20% or more) are identified. 
The ≥20% decrease in the nocturnal diuresis rate has been established as a relevant marker of 
antidiurectic responsivenes in previous nocturia trials with an active run-in (Lose, 2003; 
Mattiasson, 2002). The NUV is defined as the total urine volume from 5 minutes after bedtime with 
the intention to sleep until the first void within 30 minutes of rising in the morning. Total time in 
bed is a proxy for the time the subject is in nocturnal diuresis. The nocturnal diuresis rate is 
calculated from the mean of 3 days NUV and total time in bed: 
𝑁𝑜𝑐𝑡𝑢𝑟𝑛𝑎𝑙 𝑑𝑖𝑢𝑟𝑒𝑠𝑖𝑠 𝑟𝑎𝑡𝑒 (𝑚𝐿/𝑚𝑖𝑛) =
NUV (mL)
Total Time in Bed (min) 
The majority of fluid output occurs via the urine, approximately 1500 mL/day, therefore threre is 
no evidence in adult nocturia subjects that the relative change over the time in nocturnal diuresis 
rate (mL/min normalised to time in bed) should be adjusted for body weight and or/body surface 
area which are both assumed to be constant over a short period of 1 week only. An analysis of 
individual nocturia subject data found that reducing NUV and increasing the duration of 
antidiuretic action of a V2-receptor agonist (desmopressin) was a significant predictor for 
subsequent decrease from baseline in the number of nocturnal voids (Yamaguchi, 2013). 
The underlying pathophysiologic mechanism of NP can be driven by either increased FWC, which 
based on mode of action will be responsive to antidiuretic treatment, or by increased sodium 
clearance, which differs substantially in mode of action and is governed by Atrial Natriuretic 
Peptide (ANP) which is directly and indirectly influenced by the Renin-Angiotensin-Aldosterone 
System (RAAS).  
The aim of the active run-in is (after excluding all other medical causes of NP) to identify subjects 
with increased FWC, which is responsive to V2-receptor agonism. In addition, safety will be 
assessed in this period with special emphasis on hyponatraemia.

Treatment group allocation will be determined by central randomisation to eliminate selection bias 
and ensure that any difference in treatment groups at baseline is a result of random chance. 
Following randomisation at Visit 4, a double-blind design has been chosen to minimise both 
investigator and subject ascertainment bias. In order to keep the treatment blinded each subject will 
receive two medications throughout the trial; an oral solution and an ODT, i.e., a double-dummy 
design will be applied because desmopressin is available in an ODT formulation and FE 201836 is 
an oral solution. The blinding is further described in Section 5.5. 
Interim analyses will be conducted throughout the trial in order to investigate the efficacy of 
FE 201836 and to reassess the randomisation probabilities for each dose of FE 201836 based on 
observed responses at the respective interim locks. In addition, serum sodium will be monitored 
during the active run-in in order to identify subjects at increased risk of developing acute 
hyponatraemia. The interim analyses are further described in Section 3.3 and Section 9.11. 
3.5.2 
Selection of Endpoints 
The change in mean number of nocturnal voids has become a standard primary clinical trial 
endpoint in nocturia trials since the first overseas trials (with desmopressin) in early 2000 
(Lose, 2003; Mattiasson, 2002; van Kerrebroeck, 2007). It is therefore reasonable and appropriate 
to use reduction in number of nocturnal voids from baseline as the primary endpoint in this trial.  
Nocturia is one of the primary causes of sleep disturbance and has been shown to impair 
functioning, quality of life, health and productivity, with those experiencing 2 or more voids per 
night reporting significant bother (Ancoli-Israel, 2011). Awakening during the first 3-4 hours of the 
night during the deep and slow-wave restorative sleep is more likely to contribute to daytime 
fatigue (Chartier-Kastler, 2006). The clinically relevant benefit (for the subject) of desmopressin 
treatment may be demonstrated further by measuring the time to first awakening to void (FUSP), 
which reduces the time spent in slow wave (deep) sleep (Bliwise, 2015). Therefore it is reasonable 
to include FUSP as an endpoint in the present trial. To further evaluate the clinical benefit of 
FE 201836 endpoints relating to percentage of nights with at most one nocturnal void or with 
complete response are included for analysis. 
The significant impact of nocturia and its treatment on subjects’ quality of life and daily lives will 
be documented by the use of an e-Diary which contains a 3-day voiding diary, NI Diary and PRO 
questionnaires. Voiding diaries are standard tools used within the urology area 
(Holm-Larsen, 2009) and are among the best possible means of obtaining objective data on 
subjective symptoms (Abrams, 1983). A voiding diary therefore represents a self-monitoring daily 
record of the individual’s voiding behaviour. The ICS recommends inclusion of voiding diaries in 
clinical assessment of subjects with LUTS (Abrams, 2002). The subjects will be asked to complete 
voiding diaries over 3 consecutive 24-hour periods just prior to scheduled visits throughout the 
trial. Three-day voiding diaries have been shown to be as effective as 7-day diaries with the 
potential for better accuracy (Dmochowski, 2005). 
The NI Diary, is a 12-item PRO measure assessing the impact burden associated with nocturia 
(Holm-Larsen, 2014). The NI Diary has been developed and psychometrically evaluated in patients 
with nocturia, in line with published International Society for Quality of Life Research (ISOQOL)

(Patrick, 2011; Reeve, 2013), as well as the Food and Drug Administration (FDA) Guidance for 
Industry, Patient-Reported Outcome Measures, 2009 (FDA, 2009). 
The PGI-S and PGI-I questionnaires, developed for use in populations with urinary tract conditions 
(Viktrup, 2012; Yalcin, 2003), are included to support anchor-based analysis of the NI Diary, as 
described in Section 10.3.1. 
To further assess the change in subjective bothersomeness of nocturia, trial participants will be 
asked, “How much has this frequency of night-time urination bothered you?” with response options 
including “not at all,” “slightly,” “moderately,” “quite a bit,” and “extremely.” This 5 point Likert 
scale has previously been used in a large epidemiological study (Hsu, 2015). 
The ISI is a PRO instrument to quantify the subject's perception of his/her insomnia severity, it is 
included as a measure of sleep quality. The ISI targets the subjective symptoms and consequences 
of insomnia as well as the degree of concern or distress caused by those difficulties (Bastien, 2001).

Method of Assigning Subjects to Treatment Groups 
4.2.1 
Recruitment 
Subjects who have given written informed consent will receive a unique (site-specific) screening 
number and be invited to perform a screening visit (Visit 1). 
All screening assessments must be completed and evaluated to confirm that all eligibility criteria 
are met by the subject. A site-specific Screening Log, for recording of details of all subjects 
screened and confirmation of eligibility or recording of reasons for screening failure, as applicable, 
must be maintained at the trial site. The screening number, which will be allocated sequentially in 
the order in which the subjects are screened, must be entered into the Screening Log. 
It is permitted to re-screen a subject in this trial in case a subject has been considered a screening 
failure due to one or more of the following reasons: 
• 
not fulfilling the inclusion criterion number 6 as defined in Clinical Trial Protocol versions 
2.0 (>250 mL), 3.0 (>250 mL), or 4.0 (≥250 mL) but had at least 1 single voided volume 
≥200 mL prior to Visit 2 
• 
not fulfilling the inclusion criterion of an NI Diary Total Score of ≥10 points (raw score) 
prior to Visit 2 (inclusion criterion number 8) as defined in Clinical Trial Protocol versions 
2.0 and 3.0 
• 
fulfilling the exclusion criterion of a serum triglyceride level >400 mg/dL (exclusion 
criterion number 12) as defined in Clinical Trial Protocol version 2.0 
• 
fulfilling the exclusion criterion of aspartate aminotransferase and/or alanine 
aminotransferase levels >2x the upper limit of normal range and a total bilirubin level 
>1.5 mg/dL (second part of exclusion criterion number 19) as defined in Clinical Trial 
Protocol version 2.0 
• 
fulfilling exclusion criterion number 3 as defined in Clinical Trial Protocol versions 2.0, 3.0, 
and 4.0 
• 
fulfilling exclusion criterion number 5 as defined in Clinical Trial Protocol versions 2.0, 3.0, 
and 4.0 
• 
fulfilling exclusion criterion number 25 as defined in Clinical Trial Protocol versions 2.0, 
3.0, and 4.0 
• 
technical issues with the e-Diary device prior to Visit 2 
If a subject has failed screening due to any other reason the subject must not be re-screened for 
participation in the trial at a later time.

4.2.2 
Randomisation 
A computer-generated randomisation list will be prepared prior to enrolment of the first subject into 
the trial. The randomisation list will be adjusted during the course of the trial via a response-
adaptive randomisation procedure. At least 50% of subjects should be randomised at trial sites in 
the USA to allow for an optimised validation of the NI Diary. Therefore, a cap of maximum 
150 subjects will need to be set for countries other than the USA. 
Subject-specific randomisation numbers will be allocated in the order at which the subjects are 
being randomised into the trial. The subject randomisation number will be recorded in the 
Screening Log. It is not permitted for a subject to be randomised in the trial twice. 
The first 125 subjects will be randomised to treatment in a fixed manner. The allocation ratio is 
2:2:1 for placebo, 500 µg FE 201836 and desmopressin. At the first interim analysis, after 
125 subjects being randomised, the allocation ratio is 2:7:1 for placebo, active treatment and 
desmopressin, respectively. Subjects will be randomised to the active treatment groups of 
FE 201836 in a response-adaptive randomisation manner. A pre-defined algorithm will be used to 
determine the relative randomisation to each of the FE 201836 groups. Subsequent interim analyses 
will be conducted every 8 weeks to adjust the adaptive randomisation probabilities. The enrolment 
of subjects will continue without any stop at the interim analyses. For more information regarding 
the interim analyses, please refer to Section 3.3 and Section 9.11. 
The screening rate will be monitored such that the accrual of randomised subjects does not 
overshoot the operating characteristics described in Section 9.1, which could potentially result in a 
loss of statistical power. 
4.2.2.1 
Randomisation if Maximum Dose is Lowered 
The trial has been designed with the option to decrease the maximum dose of FE 201836 from 
500 µg to 350 µg if recommended by the DMC (Section 9.11.1). If this decision is made, 
randomisation to the 500 µg FE 201836 treatment group will be closed, the trial will continue with 
350 µg FE 201836 as the highest dose for the active run-in and the highest dose of FE 201836 that 
any subject can be randomised to. In case subjects have already been randomised to the 500 µg 
FE 201836 treatment group and have not completed the trial, the DMC will recommend whether or 
not these subjects may be permitted to remain on treatment with 500 µg FE 201836 for the 
remainder of the trial. Subjects randomised to treatment with 500 µg FE 201836 who prematurely 
discontinue the trial due to DMC decision (Section 4.4) may be replaced by subjects randomised to 
treatment with a lower dose of FE 201836. 
If the decision to close randomisation to 500 µg FE 201836 is taken prior to the first interim 
analysis, i.e., when the first 125 subjects have been randomised, the remaining subjects will be 
randomised to the following treatment groups: placebo, desmopressin (25 µg for females and 50 µg 
for males) or 350 µg FE 201836. After the first interim analysis the dose-response adaptive 
randomisation will allocate subjects to the remaining 7 open treatment groups: placebo, 50 µg 
FE 201836, 100 µg FE 201836, 150 µg FE 201836, 250 µg FE 201836, 350 µg FE 201836, or 
desmopressin (25 µg for females and 50 µg for males).

4.3.3 
Lifestyle Changes and Other Restrictions 
In order to prevent hyponatraemia and to avoid interference with efficacy assessment of the 
treatment: 
• 
The fluid intake must be limited to a minimum (to satisfy thirst only) during the time 
interval of 1 hour before, until 8 hours after administration of IMP 
• 
The subject should empty the bladder before going to bed with the intention to sleep 
• 
The treatment should be interrupted during acute intercurrent illnesses characterised by fluid 
and/or electrolyte imbalance (such as systemic infections, fever, gastroenteritis) until the 
subject has fully recovered. The treatment can be re-started at the discretion of the 
investigator once the condition of the subject is stabilised 
Subjects will be reminded to follow instructions regarding lifestyle changes throughout the duration 
of the trial. 
Subjects participating in the present trial should refrain from donating blood or sperm throughout 
the trial period. 
4.3.4 
Contraception 
Female subjects of child-bearing potential must be willing and able to use an acceptable effective 
contraceptive method throughout the trial. Documentation of the method used must be available. A 
female subject is considered to be of child-bearing potential following menarche and until 
becoming post-menopauseal, unless permanently sterile. Post-menopausal is defined as amenorrhea 
of >12 months duration based on the reported date of the last menstrual period. 
In the context of this trial, acceptable effective methods include: 
• Transdermal patch 
• Established use of oral, injected or implanted hormonal methods of contraception 
• Placement of an intrauterine device (IUD) or intrauterine system (IUS) 
• Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault 
caps) with spermicidal foam/gel/film/cream/suppository 
• Male sterilisation (with the appropriate post-vasectomy documentation of the absence of 
sperm in the ejaculate) 
• True abstinence: When this is in line with the preferred and usual lifestyle of the subject 
Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus 
interruptus), spermicides only, and lactational amenorrhoea method (LAM) are not acceptable 
methods of contraception. Female condom and male condom should not be used together. 
Contraceptive measures will not be required for male subjects participating in the trial based on 
genotoxicity data obtained in animal studies with FE 201836, as detailed in the Investigator’s 
Brochure.

4.4 
Withdrawal Criteria 
A subject must be withdrawn from the trial in case of: 
• 
Serum sodium level is ≤125 mmol/L at any time point during the trial 
• 
Significant non-compliance with the trial protocol, as judged by the investigator and/or the 
sponsor 
• 
Other medical or safety reasons, as judged by the investigator and/or the sponsor 
• 
The subject wishes to discontinue for any reason 
A subject has the right to withdraw from the trial at any time for any reason, without the need to 
justify his/her decision. However, the investigator should record the reason for the subject’s 
withdrawal, if possible. The investigator also has the right to withdraw a subject. Since an excessive 
rate of withdrawals can render the trial devoid of meaning, unnecessary withdrawal of subjects 
should be avoided. 
Every effort should be made to invite subjects withdrawn/discontinued from the trial to an end-of-
trial visit (Visit 8) as soon as possible after a decision of withdrawal/discontinuation has been taken. 
For any discontinuation, the investigator should obtain the required information and document the 
date and reason for the premature discontinuation in the eCRF. 
In case the subject has withdrawn consent, no new data can be recorded in the eCRF. Correction of 
previous data and/or recording data related to visits/procedures done prior to but made available 
after withdrawal of consent (e.g., laboratory results) will be allowed unless the subject disapproves 
it. 
If the reason for withdrawal is an adverse event, the specific event or the main laboratory 
abnormality must be recorded in the eCRF. The investigator should make thorough efforts to 
document the outcome. 
Subjects discontinued from the trial will not be replaced, except for subjects randomised to 
treatment with 500 µg FE 201836 in case a decision is taken to decrease the maximum dose of 
FE 201836 from 500 µg to 350 µg (Section 4.2.2.1).

TREATMENTS 
5.1 
Treatments Administered 
In order to maintain the treatment blinding each subject will receive 2 medications (double-dummy 
design), an oral solution and an ODT formulation, during every treatment period of the trial, as 
outlined in Table 5-1. 
During the active run-in period all subjects will receive 500 µg FE 201836 oral solution (and 
placebo ODT) for 1 week. 
After the lifestyle changes/screening, active run-in and washout periods, eligible subjects will be 
randomised to a treatment group as follows: 
• Prior to the first interim analysis, the first 125 subjects will be randomised to the following 
treatment groups: placebo, desmopressin or 500 µg FE 201836. 
• After the first interim analysis, subjects may be randomised to one of 8 treatment groups: 
placebo, 50 µg FE 201836, 100 µg FE 201836, 150 µg FE 201836, 250 µg FE 201836, 
350 µg FE 201836, 500 µg FE 201836 or desmopressin (25 µg for females and 50 µg for 
males). 
After randomisation, the duration of treatment is 12 weeks.

FE 201836 and placebo oral solution must be stored at 2-8°C (36-46°F) before dispensing. After 
dispensing, the products should be stored at room temperature. 
Desmopressin and placebo ODT should be stored at 25°C (77ºF); excursions permitted to 15-30°C 
(59-86°F). The product should be kept in the original package to be protected from moisture and 
light. The product should be used immediately upon opening of the individual tablet blister. 
The investigator will ensure that the IMP is stored under appropriate conditions in a secure location 
with controlled access. The storage temperature shall be monitored regularly and documented in 
accordance with the instructions provided by the sponsor. Deviations in storage temperature must 
be reported to the sponsor as instructed in the IMP handling instruction. 
Returned IMP from the subjects (used/partly used or unused, including empty packaging material) 
must be stored separately from non-allocated IMP. 
The subjects will be instructed to store the IMP in accordance with the above-mentioned 
conditions. 
5.5 
Blinding/Unblinding 
5.5.1 
Blinding 
The IMP will be supplied by the sponsor in individually packed containers.  
The IMP for the randomised treatment period will be packaged according to a computer-generated 
randomisation list prepared for all trial sites. The randomisation list will not be available to any 
person involved in the conduct and evaluation of the trial until the trial database is declared clean 
and is released to the trial statistician. 
5.5.2 
Unblinding of Individual Subject Treatment  
An emergency unblinding procedure will be available for the investigator and designated personnel 
at the sponsor through the eCRF. It is the investigator’s responsibility to decide whether it is 
medically necessary to know which IMP the subject receives (i.e., unblinding) to ensure the 
subject’s welfare and safety. Breaking of the blind for individual subjects in emergency situations is 
only permitted in case of a Suspected Unexpected Serious Adverse Reaction (SUSAR), or in case 
of an adverse event where the knowledge of the IMP administered is required for medical 
management of the subject. 
As far as the emergency permits, the need to break the blind will be agreed by the investigator and 
the sponsor. The investigator who unblinds a treatment will use the eCRF and is required to enter a 
password and must record the reason for unblinding before the treatment code can be broken. It 
must also be recorded in the eCRF when, and by whom, the code was broken. The investigator 
must record the event of unblinding in the subject’s medical record, including the reason for 
unblinding. 
If the sponsor needs to unblind a treatment, the eCRF will be used for unblinding. It is a 
requirement to enter a password and the reason for unblinding before the treatment code can be 
broken. It must also be recorded in the eCRF when and by whom the code was broken.

It may be necessary to unblind an individual subject’s treatment schedule for the purposes of 
expedited reporting to the authorities and/or Independent Ethics Committees (IECs)/Institutional 
Review Boards (IRBs)/Research Ethics Boards (REBs). In that situation, every effort should be 
made to maintain blinding of the sponsor personnel involved in data analysis and interpretation. 
Other personnel may be unblinded for SUSARs, including trial site personnel as well as personnel 
acting on behalf of the sponsor. 
Information on whether the blind has been broken for any subjects is available in the eCRF and 
must be collected before the database is declared clean and is released to the trial statistician. 
In case the eCRF cannot be accessed, and hence the emergency unblinding cannot be performed

Treatment Compliance 
5.6.1 
Dispensing and Accountability 
The IMP will be handled by authorised personnel at the trial site according to instructions provided 
by the sponsor. 
The IMP for the active run-in will only be dispensed to subjects who meet the eligibility criteria at 
Visit 2. 
The IMP for the randomised treatment period will only be dispensed to subjects who meet the 
eligibility criteria at Visit 4 and are randomised into the trial.  
The investigator (or his/her designee) will maintain a Drug Dispensing Log detailing the dates and 
quantities of IMP dispensed to, and used by each subject, as well as the batch number(s).  
Each subject should return all unused and used IMP bottles and ODT blister sheets (empty foils) to 
the trial site. The delegated designee at each trial site will reconcile all used and unused IMP and 
maintain all IMP (including empty bottles and ODT blister/foils) for drug accountability. The 
monitor will verify the drug accountability during the trial. 
5.6.2 
Assessment of Compliance 
Treatment compliance will be verified at Visits 3, 5, 6, 7 and 8, by reviewing the used, partly used 
and unused IMP and/or subject’s statements documented in the source documents in case the IMP 
is lost. 
5.7 
Return and Destruction of Investigational Medicinal Products 
Subjects will be asked to return unused and used IMP bottles and ODT blister sheets. Used and 
partly used IMP bottles and blisters (foils) will be destroyed at the trial site according to local 
regulations and standard procedures at the site, after the drug accountability has been verified by

TRIAL PROCEDURES 
The investigator is obliged to keep logs of all screened and randomised subjects. Each subject will 
receive a unique screening number available at each trial site. Prior to, or at Visit 1, all subjects 
must receive a detailed explanation (verbal and written information) of the trial and must sign an 
Informed Consent Form (ICF) after having had sufficient time to consider the participation in the 
trial. No trial-related procedures must be performed on the subject prior to signing the ICF.

During the 1-week washout period, each subject must complete a 3-day voiding diary to confirm 
the eligibility for the trial. The voiding diary should be completed over 3 consecutive 24-hour 
periods just prior to Visit 4. 
After randomisation (Visit 4) each subject has to complete four 3-day voiding diaries prior to the 
scheduled trial visits.  
Nocturnal voids are defined as the voids occurring from 5 minutes after bedtime, with the intention 
to sleep at night, until rising in the morning. The first morning void will not be counted as a 
nocturnal void even though its volume is included as part of the NUV. The time to first void is 
defined as the time from bedtime with the intention to sleep until first nocturnal void. 
The sponsor will provide the subjects with cups for measuring the urine volume. 
Prior to each visit the subjects will receive reminders to complete the e-Diary.  
7.1.1.2 
Nocturia Impact Diary 
Nocturia has wide-ranging implications for patients’ quality of life, mainly through persistent, 
repeated sleep interruptions. Valid patient self-reported assessments of disease burden and benefit 
of therapy are essential to evaluate the full clinical value of treatment for the patient.  
The NI Diary is a validated, nocturia-specific tool available in multiple languages and consists of a 
12-item questionnaire with 11 core items (Q1-Q11) and an overall QoL impact question (Q12) 
(Holm-Larsen, 2014). It is used in conjunction with a voiding diary to capture patient reported 
consequences of nocturia and its treatment. It has a recall period of one night and day. Responses 
are scored from 0 to 4 (lowest to highest impact). For Question 12, response options range from 
0 (not at all) to 4 (a great deal). The NI Diary total scores are calculated by summing the 11 core 
items. The NI Diary total and overall impact scores are standardised from 0 to 100 (lowest to 
highest impact).  
The NI Diary will be included in the e-Diary (Section 7.1.1), which will be completed by the 
subjects at home, for the 3 consecutive days just prior to scheduled visits as outlined in Figure 3-2 
and Figure 3-3. The NI Diary should be completed in the evening and before completing the PGI-S 
and PGI-I questionnaires. 
One objective of this trial is to further validate the NI Diary, as well as to establish what constitutes 
a meaningful change in the NI Diary Total Score. Thus, the disease-specific NI Diary will be 
further tested and validated in connection with this trial. This will be done through pshychometric 
validation, as described in Section 10.3.1.1, and through exit interviews, as described in 
Section 10.3.1.2.

Patient Reported Outcomes 
The PRO instruments (questionnaires) that will be used in the trial are listed below. They should be 
completed in the following order: 
• At home in the evening (after completion of the NI Diary): 
o Patient Global Impression of Severity (PGI-S) 
o Patient Global Impression of Improvement (PGI-I) 
• At the trial site: 
o Insomnia Severity Index (ISI) 
o Bother (Hsu 5-point Likert Bother Scale) 
The two PRO questionnaires that will be completed at the trial site (ISI and Hsu 5-point Likert 
Bother Scale) are recommended to be completed before any other assessments are performed, by 
the subject in a quiet place without influence from the trial personnel or accompanying family or 
friends. It is not permitted to help the subject choose an answer or interpret or rephrase questions 
which the subject does not understand. The subjects should be informed that there are no right or 
wrong answers and that all of the subjects’ responses will remain confidential. 
7.1.1.3.1 Patient Global Impression of Severity and Patient Global Impression of Disease 
Improvement 
Patient Global Impression of Disease scales are commonly used measures of symptom severity, 
treatment response and the efficacy of treatments (Yalcin, 2003). The PGI-I and PGI-S will be 
included in the trial to indicate change or stability in global health status for anchor-based analyses 
to identify thresholds for clinically important changes in, e.g., NI Diary scores and number of 
nocturnal voids, as described in a separate Psychometric Analysis Plan (PAP). Moreover, both 
scales will be analysed for treatment effect, as described in Section 9.7.3. To better reflect the 
current condition, the revised and patient-tested versions of PGI-I and PGI-S will refer to ‘night-
time voiding’, as compared to ‘LUTS’ (Viktrup, 2012). 
The PGI-S is a prospective measure that measures a patient’s current severity reported as “None,” 
“Mild,” “Moderate,” or “Severe” (coded as 1-4). Scores on this measure will provide a patient-rated 
summary of the severity of the patient’s nocturia symptoms. 
The PGI-I is a retrospective measure. It will provide a patient-rated summary of change in nocturia 
since the start of trial treatment, reported as “Very much better,” “Much better,” “A little better,” 
“No change,” “A little worse,” “Much worse,” or “Very much worse,” (coded as 1-7). 
PGI-S followed by PGI-I will be completed by the subjects at home in the evening immediately 
after completing the NI Diary, as outlined in Figure 3-2 and Figure 3-3. 
7.1.1.3.2 Insomnia Severity Index 
Chronic disruptions of sleep will have consequences for daytime performance and well-being. 
Nocturia patients often report excessive daytime sleepiness, with some experiencing more severe 
symptoms, including increased rates of mood disorders and decrease of physical health. Fatigue is a

commonly reported symptom by individuals and causes a great amount of interferences with daily 
life. Sleepiness has also been linked to increased risks for accidents, such as falling asleep while 
driving or work-related accidents (Asplund, 2005; Ancoli-Israel, 2011).  
Nocturia is characterised by shortening the FUSP. The first sleep period is of high importance due 
to that deepest stages of sleep (most restorative sleep) typically occur within the first few hours of 
the sleeping and once these stages are interrupted by wakening (e.g., to void) patients are not able 
to make up for this during the rest of the night (Bliwise, 2015). FUSP will be a secondary endpoint 
in the trial. 
Sleep quality will be measured through the ISI, which is an instrument to quantify the subject's 
perception of his/her insomnia severity. The ISI targets the subjective symptoms and consequences 
of insomnia as well as the degree of concern or distress caused by those difficulties (Bastien, 2001). 
The ISI comprises of four `sleep-related' items and three `wake-related' items assessing the severity 
of sleep-onset and sleep maintenance difficulties (both nocturnal and early morning awakenings), 
satisfaction with current sleep pattern, interference with daily functioning, noticeability of 
impairment attributed to the sleep problem and degree of distress or concern caused by the sleep 
problem. Each item is rated on a 0-4 scale and the total score ranges from 0 to 28. A higher score 
suggests more severe insomnia. 
The self-administered ISI questionnaire will be completed at the trial site by the subject before 
active run-in period (Visit 2), at the randomisation visit (Visit 4), after 4 weeks (Visit 6), after 
8 weeks (Visit 7) and at the last trial visit after 12 weeks of treatment (Visit 8) as illustrated in 
Figure 3-2 and Figure 3-3. Since the ISI has a two-week recall, a reminder to think back two weeks 
will appear on the screen upon start of completion, in order to improve on quality of the 
information captured. The ISI will be completed at Visit 2 in order to compare insomnia severity to 
other diseases presenting with insomnia, as recorded by the ISI. The ISI completed at the remaining 
visits (Visits 4, 6, 7 and 8) will be used to measure treatment effect. 
7.1.1.3.3 Bother 
Patient bother is a broad concept covering aspects such as impact on sleep, daily life, social life, 
mental health, fatigue, etc. (Tikkinen, 2010). It has been shown that most nocturia patients are not 
very bothered by one nightly void, but that there is clearly a bother threshold at two voids or more. 
Moreover, comparing two adjacent voiding categories at a time, the increase was statistically 
significant with each increment in number of nightly voids. To further assess the change in 
subjective bothersomeness of nocturia, trial participants will be asked, “How much has this 
frequency of night-time urination bothered you?” with response options including “not at all,” 
“slightly,” “moderately,” “quite a bit,” and “extremely.” This 5-point Likert scale has previously 
been used in a large epidemiological study (Hsu, 2015). 
The Hsu 5-point Likert Bother Scale will be completed by the subject at the trial site at 
randomisation (Visit 4), after 1 week (Visit 5), after 4 weeks (Visit 6), after 8 weeks (Visit 7) and at 
the last trial visit after 12 weeks of treatment (Visit 8), as illustrated in Figure 3-2 and Figure 3-3.

Clinical Laboratory Variables 
Urine and blood samples for assessment of safety laboratory values (urinalysis, haematology, 
coagulation factors and clinical chemistry parameters including serum sodium) will be collected as 
presented in Table 6-1. A central laboratory will be used for the analyses (Section 7.3). Evaluation 
of the laboratory-based eligibility criteria will be determined by the central laboratory results. The 
analytical parameters are listed in Table 7-3. 
Details for handling of serum sodium samples are given in Section 7.1.3.1. 
Laboratory values will be reported to the investigator. Laboratory reports from the screening visit 
(Visit 1) must be available for evaluating the inclusion and exclusion criteria prior to the active run-
in period (Visit 2) and before randomisation (Visit 4). Measurements outside normal ranges will be 
assessed by the investigator as ‘abnormal, not clinically significant’ or ‘abnormal, clinically 
significant’. Any abnormal, clinically significant changes should be reported as adverse events 
(Section 8.2). The laboratory reports will be signed and dated by the investigator.

7.1.3.1 
Serum Sodium 
Serum sodium levels will be monitored throughout the trial as hyponatraemia is a potentially 
serious adverse drug reaction (ADR) associated with desmopressin treatment and may potentially 
be associated with FE 201836 treatment. 
A central laboratory will be used. However, a local laboratory may be used in addition to the 
central laboratory if a quick turn-around time of the result is needed. In such case a sample must 
also be sent to the central laboratory. Evaluation of the laboratory-based eligibility criteria will be 
determined by the central laboratory results. All serum sodium values must be reviewed as soon as 
possible after the results are available. Any unexpected low serum sodium value must be re-tested. 
Any significant changes in serum sodium, judged by the investigator as clinically significant must 
be reported as adverse events, as described in Section 8.2. 
Blood samples for analysis of serum sodium will be collected, preferably in the morning, at 
Visits 1, 3, 5, 6, 7 and 8, as presented in Table 6-1. The risk for subjects developing hyponatraemia 
during the trial period will be mitigated as follows (serum monitoring plan): 
Screening (Visit 1) 
All subjects must have normal serum sodium (≥135 mmol/L) at screening (Visit 1). If the serum 
sodium value is <135 mmol/L (re-tested and confirmed, with results available within 7 days) the 
subject must be discontinued from the trial as a ‘screening failure’. 
Active Run-in Period 
During the 1-week active run-in period, 4 days (±1 day) after the planned start of IMP treatment, 
the subject will be telephoned to follow-up on safety. 
Visit 3 
At Visit 3 (after the active run-in), if the serum sodium value is <130 mmol/L the investigator must 
immediately contact the subject and schedule visits for further evaluation. If the serum sodium 
value is <130 mmol/L (re-tested and confirmed, with results available within 7 days) the subject 
will not be randomised to the trial and must be discontinued from the trial as a ‘screening failure’. 
The subject will be followed (by the investigator) for safety until the serum sodium level is stable 
and not clinically significant, preferably until at least ≥135 mmol/L. 
If the subject cannot attend Visit 3 as planned, arrangements must be made to test the serum sodium 
level at Day 6-8 from the IMP start date to ensure the serum sodium level is measured while the 
subject is taking IMP. 
12-week Randomised Treatment Period 
During the 12 weeks randomised treatment period, any unexpected low serum sodium value 
(<135 mmol/L or a drop in serum sodium level >10 mmol/L) must be re-tested with at least 
2 additional consecutive tests to identify the nadir and duration of the hyponatraemic episode. The 
serum sodium level should be re-tested within 5 (±2 days) since the previous test. The subject will 
be followed (by the investigator) for safety until the serum sodium level is stable and not clinically 
significant, preferably until at least ≥135 mmol/L.

Any Time Point during the Trial 
If the serum sodium value is ≤125 mmol/L at any time point during the trial, the treatment with the 
IMP must be stopped immediately and the subject must be withdrawn from the trial. All cases of 
serum sodium values ≤125 mmol/L will be reported as Serious Adverse Event (SAEs) 
(Section 8.5). The subject will be followed (by the investigator) for safety until the serum sodium 
level is stable and not clinically significant, preferably until at least ≥135 mmol/L. 
Acute Intercurrent Illness 
In case of acute intercurrent illnesses characterised by fluid and/or electrolyte imbalance (such as 
systemic infections, fever, gastroenteritis), the treatment with IMP should be interrupted until the 
subject has fully recovered. The treatment can be re-started at the discretion of the investigator once 
the condition of the subject is stabilised. 
In addition, subjects may be called in for additional unscheduled visits due to safety reason, as 
described in Section 6.8. 
Additional Serum Sodium Testing 
Events that will trigger additional serum sodium testing include, but are not limited to, the 
following: 
• If more than 21 days elapse from the serum sodium measurement at Visit 1 and the visit 
date of Visit 2, the serum sodium measurement must be re-tested, with results available 
prior to Visit 2. 
• A subject is presenting with signs or symptoms of hyponatraemia (e.g., headache, dizziness) 
• A subject has gained more than 2 kilograms in body weight between visits (Section 7.2.4) 
• If concomitant treatment with therapy that may induce hyponatraemia (Section 4.3.1) is 
initiated or dosing of an existing therapy is increased during the trial, additional serum 
sodium monitoring should be performed in the first week (4-8 days) after initiation and 
again with follow-up as judged by the investigator, at least at 4 weeks. 
7.1.3.2 
von Willebrand Factor and Factor VIII 
Blood samples for assessment of coagulation factors will be collected at Visits 1, 4, 6 and 8. 
The concentrations of the coagulation factors von Willebrand Factor (vWF) and Factor VIII (FVIII) 
were assessed in the phase 1 clinical trial, 000195, after both oral and intravenous administration of 
FE 201836. The results indicated that both vWF and FVIII were increased at high plasma 
concentrations of FE 201836. vWF started to increase at a plasma concentration of approximately 
150 pg/mL FE 201836 and FVIII at a plasma concentration of approximately 200 pg/mL. Such high 
plasma concentrations are unlikely to be reached in the urological doses proposed for the present 
trial, however, vWF and FVIII will be measured as a safety precaution, and to ensure that these 
coagulation factors are not released in clinically significant amounts.

7.1.3.3 
Copeptin 
Blood samples for exploratory analysis of copeptin levels in plasma will be collected at Visit 2, 
Visit 4 and Visit 8. The biomarker copeptin can be easily tested for, and is therefore used as an 
AVP surrogate to potentially identify low nocturnal vasopressin levels in plasma. In patients with 
NP, an inverse circadian rhythm of vasopressin is suspected, resulting in low nocturnal 
concentrations, which may be the root cause of NP. Copeptin may be a useful biomarker to 
diagnose NP due to low levels of endogenous AVP, thereby identifying the ideal candidate for 
antidiuretic therapy (Brunell, 2016) and consequently treatment with FE 201836. 
7.1.4 
Vital Signs 
Diastolic and systolic blood pressure (mm Hg) and heart rate (beats per minute) will be measured 
after resting for 5 minutes in a sitting position, according to usual clinical practice at all trial visits. 
Measurements outside normal ranges will be assessed by the investigator as ‘abnormal, not 
clinically significant’ or ‘abnormal, clinically significant’. Any abnormal, clinically significant 
changes should be reported as adverse events. 
7.1.5 
24-Hour Urine Volume and Nocturnal Urine Volume 
Data on 24-hour urine volume, i.e., including NUV, will be obtained from the 3-day voiding diary 
(Section 7.1.1.1) completed prior to Visits 2, 4, 5 and 8. In addition, NUV data will be obtained 
from the 3-day voiding diary completed prior to Visit 3 (Table 7-1). 
7.2 
Other Assessments 
7.2.1 
Demographics 
Demographic data, including date of birth and race, will be collected at screening (Visit 1). 
7.2.2 
Medical History 
Information on clinically significant previous and concomitant illnesses, signs or findings from 
assessments and examinations during the screening, including surgical history, will be recorded as 
medical history at the screening visit (Visit 1). 
7.2.3 
Concomitant Medication 
Information on concomitant medications will be collected at each visit throughout the trial, as 
described in Section 4.3.1. Concomitant medications are defined as any medication, other than the 
IMP, taken by the subject at entry and during the trial. Prohibited medications/therapies are listed in 
Section 4.3.2. 
7.2.4 
Body Weight and Height 
Body weight and height will be measured to calculate the body mass index (BMI). The eCRF will 
be configured to automatically calculate the BMI. Height (without shoes) will be measured at 
screening (Visit 1).

Body weight (without overcoat and shoes) will be measured at all visits. The same scale should 
preferably be used on the subject during the course of the trial for consistency in readings. 
If the subject has gained more than 2 kilograms between trial visits, the serum sodium level must be 
measured, as described in Section 7.1.3.1. 
7.2.5 
Physical Examination 
Physical examinations will be performed at Visits 1, 4 and 8 by the investigator or a delegated 
sub-investigator (MD, Medical Doctor; DO, Doctor of Osteopathic Medicine; PA, Physician 
Assistant; NP, Nurse Practitioner) and must not be delegated to any other trial site personnel. The 
same individual should preferably perform the physical examinations for a subject for consistency 
in evaluation.  
A complete physical examination will include, at a minimum, assessments of the cardiovascular, 
respiratory, gastrointestinal, urological and neurological systems. Any abnormal, clinically 
significant changes should be reported as adverse events. 
7.2.6 
Pregnancy Test 
A serum pregnancy test will be performed in all pre- and peri-menopausal female subjects at 
screening (Visit 1), Visit 4 and at the end-of-trial visit (Visit 8). A urine pregnancy test will also be 
performed at screening (Visit 1). 
Female subjects of childbearing potential must have documentation of an acceptable effective 
method of contraception, as described in Section 4.3.4. Amenorrhea of >12 months duration based 
on the reported date of the last menstrual period is sufficient documentation of post-menopausal 
status and does not require a pregnancy test. 
7.2.7 
Electrocardiogram 
A 12-lead ECG will be performed by the investigator or appropriate designee at the screening visit 
(Visit 1) and at the end-of-trial visit (Visit 8). The ECG should be taken after resting for 5 minutes. 
The ECG print-out should be reviewed, signed and dated by the investigator. Any abnormal, 
clinically significant changes should be reported as adverse events. 
7.3 
Handling of Biological Samples 
A trial-specific laboratory manual will be provided to the participating sites, describing in detail 
how to handle, store and transport the biological samples in this trial. All biological samples will be 
analysed at central laboratories and will be destroyed after the results are available. For all 
biological samples collected in the trial, analyses beyond those described in the protocol can only 
be performed after obtaining the required approvals. The processes related to handling biological 
samples will be described in the informed consent documents and data protection legislation 
including local legislation will be adhered to. 
In addition to the central laboratory, a local laboratory may be used for analysis of serum sodium if 
a quick turn-around time of the result is needed (Section 7.1.3.1).

ADVERSE EVENTS 
8.1 
Adverse Event Definition 
An adverse event is any untoward medical occurrence in a subject participating in a clinical trial. It 
includes: 
• 
Any unfavourable and unintended sign, symptom or disease temporally associated with the 
use of the IMP, whether or not considered to be caused by the IMP. 
• 
Adverse events commonly observed and adverse events anticipated based on the 
pharmacological effect of the IMP. 
• 
Any laboratory abnormality, vital sign or finding from physical examination assessed as 
clinically significant by the investigator (note: pre-existing conditions diagnosed through 
assessments and examinations at the screening visit or during the screening period are not 
adverse events, but are recorded as medical history). 
• 
Accidental injuries, reasons for any change in medication (drug and/or dose), reasons for 
any medical, nursing or pharmacy consultation, or reasons for admission to hospital or 
surgical procedures. 
• 
Overdoses and medication errors with and without clinical consequences. 
8.2 
Collection and Recording of Adverse Events 
8.2.1 
Collection of Adverse Events 
The investigator must monitor the condition of the subject throughout the trial from the time of 
obtaining informed consent until the last visit. 
The sources of adverse events cover: 
• 
The subject’s response to questions about his/her health (a standard non-leading question 
such as “How have you been feeling since your last visit?” is asked at each visit). 
• 
Symptoms spontaneously reported by the subject. 
• 
Investigations and examinations where the findings are assessed by the investigator to be 
clinically significant changes or abnormalities. 
• 
Other information relating to the subject’s health becoming known to the investigator (e.g., 
hospitalisation). 
8.2.2 
Recording of Adverse Events 
The investigator must record all adverse events in the Adverse Event Log provided in each 
subject’s eCRF with information about: 
• 
Adverse event 
• 
Date and time of onset (time can be omitted, if applicable) 
• 
Intensity 
•

Seriousness. 
Each of the items in the Adverse Event Log is described in detail in the following sections. 
Adverse Event 
Adverse events should be recorded as diagnoses, if available. If not, separate signs and symptoms 
should be recorded. One diagnosis/symptom should be entered per record. 
If a subject suffers from the same adverse event more than once and the subject recovers in between 
the events, the adverse events should be recorded separately. If an adverse event changes in 
intensity, a worst-case approach should be used when recording the event, i.e. the highest intensity 
and the longest duration of the event.a 
Note the following: A procedure is not an adverse event; the reason for conducting the procedure is. 
Hospitalisation is not an adverse event; the reason for hospitalisation is. Death is not an adverse 
event, but the cause of death is (an exception is sudden death of unknown cause, which is an 
adverse event). 
Date and Time of Onset 
The date of onset is the date when the first sign(s) or symptom(s) were first noted. If the adverse 
event is an abnormal clinically significant laboratory test or outcome of an examination, the onset 
date is the date the sample was taken or the examination was performed.  
Intensity 
The intensity of an adverse event must be classified using the following 3-point scale: 
Mild: 
Awareness of signs or symptoms, but no disruption of usual activity. 
Moderate: 
Event sufficient to affect usual activity (disturbing). 
Severe: 
Inability to work or perform usual activities (unacceptable). 
                                              
a  
Exception: if an adverse event with onset before the first IMP administration (i.e., a pre-treatment adverse 
event) worsens in intensity, this must be recorded as two separate events. The initial adverse event should be 
recorded with outcome “not recovered” and the date and time of outcome is when the intensity changed. The 
second adverse event should be recorded with date and time of onset when the intensity changed.

Causal Relationship to IMP 
The possibility of whether the IMP caused the adverse event must be classified as one of the 
following: 
Reasonable possibility:  
There is evidence or argument to suggest a causal relationship between the IMP and the adverse 
event, i.e., it is an ADR. The ADR may occur as part of the pharmacological action of the IMP or 
may be unpredictable in its occurrence. 
No reasonable possibility: 
There is no reasonable evidence or argument to suggest a causal relationship between the IMP and 
the adverse event. 
Action Taken to IMP 
The action taken to the IMP in response to an adverse event must be classified as one of the 
following: 
• 
No change (medication schedule maintained or no action taken) 
• 
Withdrawn 
• 
Interrupted 
Other Action Taken 
Adverse events requiring therapy must be treated with recognised standards of medical care to 
protect the health and well-being of the subject. Appropriate resuscitation equipment and medicines 
must be available to ensure the best possible treatment of an emergency situation. 
If medication is administered to treat the adverse event, this medication should be entered in the 
Concomitant Medication Log. 
Date and Time of Outcome 
The date and time the subject recovered or died. 
Outcome 
The outcome of an adverse event must be classified as one of the following: 
• 
Recovered (fully recovered or the condition has returned to the level observed at initiation 
of trial treatment) 
• 
Recovered with sequelae (resulted in persistent or significant disability/incapacity) 
• 
Recovering (the event is improving) 
• 
Not recovered

Adverse Events of Special Interest 
Hyponatraemia 
Serum sodium levels will be monitored throughout the trial as hyponatraemia is a well-known ADR 
associated with desmopressin treatment (Section 7.1.3.1) and may potentially be associated with 
FE 201836 treatment. Serum sodium levels should be tested in subjects presenting with signs or 
symptoms of hyponatraemia. Any significant changes in serum sodium, judged by the investigator 
as clinically significant must be reported as adverse events, as described in Section 8.2. 
All cases of serum sodium values ≤125 mmol/L are considered important medical events and must 
be reported as SAEs, as described in Section 8.5.2. 
8.4 
Pregnancy and Pregnancy Outcome 
If a pregnancy occurs, the IMP should be immediately stopped for the pregnant subject and Global 
Pharmacovigilance at Ferring Pharmaceuticals A/S must be informed. The pregnancy should be 
reported via the pregnancy Report Form included in the eCRF system. In case the eCRF cannot be 
accessed and hence the Pregnancy Report Form cannot be filled in within the eCRF system, a paper 
Pregnancy Report Form available in the investigator’s file should be used and sent to Ferring 
Global Pharmacovigilance. Contact details to Ferring Global Pharmacovigilance are provided in 
Section 8.5.2. 
A pregnant participant or the partner of a male participant should be followed until termination or 
until term to ensure absence of congenital anomaly or birth defect that may have resulted from 
maternal exposure or transmission of the study drug via semen following paternal exposure. The 
pregnancy should be followed-up at least until the birth of the infant and 4-6 weeks after the birth 
of the infant. In general, the follow-up will include the course; duration and the outcome of the 
pregnancy as well as neonatal health. 
If a pregnancy results in an abnormal outcome (birth defect/congenital anomaly) this must be 
reported as an SAE to Global Pharmacovigilance at Ferring Pharmaceuticals A/S.

Serious Adverse Events 
8.5.1 
Serious Adverse Event Definition 
Table 8-1 
Serious Adverse Events during the Trial 
An event is defined a serious 
adverse event if it: 
Guidance 
results in death 
Any event resulting in a fatal outcome must be fully documented and reported, 
including deaths occurring within 4 weeks after the treatment ends and irrespective of 
the causal relationship to the IMP. The death of a subject enrolled in a trial is per se 
not an event, but an outcome. 
is life-threatening 
The term life-threatening refers to an adverse event in which the subject was at 
immediate risk of death at the time of the event. It does not refer to an event, which 
may have caused death if it were more severe. 
requires in-patient 
hospitalisation or 
prolongation of existing 
hospitalisation 
The term hospitalisation means that the subject was admitted to hospital or that 
existing hospitalisation was extended as a result of an event. Hospitalisation describes 
a period of at least 24 hours. Over-night stay for observation, stay at emergency room 
or treatment on an out-patient basis do not constitute a hospitalisation. However, 
medical judgement must always be exercised and when in doubt the case should be 
considered serious (i.e., if case fulfils the criterion for a medically important event). 
Hospitalisations for administrative or social purposes do not constitute an SAE. 
Hospital admissions and/or surgical operations planned before trial inclusion are not 
considered adverse events, if the illness or disease existed before the subject was 
enrolled in the trial, provided that the condition did not deteriorate during the trial. 
results in persistent or 
significant 
disability/incapacity 
Disability/incapacity means a substantial disruption of a person’s ability to conduct 
normal life functions. In doubt, the decision should be left to medical judgement by 
the investigator. 
is a congenital anomaly/birth 
defect 
Congenital anomaly/birth defect observed in any offspring of the subject conceived 
during treatment with the IMP. 
is an important medical 
event 
Important medical events are events that may not be immediately life-threatening or 
result in death or hospitalisation but may jeopardise the subject or may require 
intervention to prevent one of the other outcomes listed in the definition above. 
Examples of important medical events include adverse events that suggest a 
significant hazard, contraindication or precaution, occurrence of malignancy or 
development of drug dependency or drug abuse. Medical and scientific judgement 
should be exercised in deciding whether events qualify as medically important. 
Important medical events include any suspected transmission of an infectious agent 
via a medicinal product. Any organism virus or infectious particle (e.g., prion protein 
transmitting Transmissible Spongiform Encephalopathy), pathogenic or non-
pathogenic, is considered an infectious agent. A transmission of an infectious agent 
may be suspected from clinical symptoms or laboratory findings indicating an 
infection in a subject exposed to a medicinal product.

Collection, Recording and Reporting of Serious Adverse Events 
SAE Reporting by the Investigator 
An SAE must be reported immediately to Ferring Global Pharmacovigilance as soon as it becomes 
known to the investigator and not later than within 24 hours of their knowledge of the occurrence of 
an SAE. 
The investigator is responsible for submitting the completed SAE Report Form with the fullest 
possible details within 3 calendar days of his/her knowledge of the SAE. 
The SAE Report Form is included in the eCRF system and must be completed. In case the eCRF 
cannot be accessed and hence the SAE Report Form cannot be filled in within the eCRF system, a 
paper SAE Report Form available in the investigator’s file should be used and sent to Ferring 
Global Pharmacovigilance using the contact details below: 
Global Pharmacovigilance, Ferring Pharmaceuticals A/S 
E-mail: 
 
Fax: 
 
eCRF information regarding demographics, adverse events, medical history and concomitant 
medication is mandatory for initial reports and for follow-up reports if any changes have been 
made since the initial report. 
Additional information relevant to the SAE such as hospital records, results from investigations, 
e.g. laboratory parameters (that are not already uploaded in the eCRF), invasive procedures, scans 
and x-rays and autopsy results can be faxed or scanned and e-mailed to Ferring Global 
Pharmacovigilance using the contact details in the section above. In any case this information must 
be supplied by the investigator upon request from the sponsor. On any copies provided, such details 
such as subject’s name, address and hospital ID number should be concealed and instead subject 
number should be provided. 
The investigator will supply the sponsor and the IEC/IRB/REB with any additional requested 
information such as results of post-mortem examinations and hospital records. 
Expedited Reporting by the Sponsor 
The sponsor will report all adverse events that are serious, unexpected and with a reasonable 
possible causality to the IMP (referred to as suspected unexpected serious adverse reactions 
[SUSARs]) as judged by either the investigator or the sponsor to the relevant parties (i.e., 
investigators, IECs/IRBs/REBs and regulatory authorities) within the stipulated timelines. The 
expectedness is assessed by the sponsor according to the current Investigator’s Brochure for 
FE 201836. Unblinded SAEs will be assessed using the current relevant reference safety 
information, which for FE 201836 is in the Investigator’s Brochure and for desmopressin in the 
Decentralised Procedure NOCDURNA Summary of Product Characteristics. 
SAEs will be considered reportable regardless of whether or not the IMP was used in accordance 
with the provisions in the protocol and the applicable reference safety information document.

Follow-up of Adverse Events and Serious Adverse Events  
8.6.1 
Follow-up of Adverse Events with Onset during the Trial 
During the trial, the investigator must follow-up on each adverse event until it is resolved or until 
the medical condition of the subject is stable. 
After the subject’s last visit, the investigator must follow-up on any adverse event classified as 
serious or considered to have a reasonable possible causality to the IMP until it is resolved or until 
the medical condition of the subject is stable. All such relevant follow-up information must be 
reported to the sponsor. If the event is a chronic condition, the investigator and the sponsor may 
agree that further follow-up is not required. 
8.6.2 
Collection of Serious Adverse Events with Onset after Last Visit in the Trial 
If an investigator becomes aware of an SAE after the subject’s last visit and he/she assesses the 
SAE to have a reasonable possible causality to the IMP, the case will have to be reported to the 
sponsor via the paper SAE Report Form, regardless how long after the end of the trial this takes 
place.

STATISTICAL METHODS 
The Global Biometrics Department at Ferring Pharmaceuticals A/S will be responsible for data 
management, the Statistical Analysis Plan (SAP) and the statistical analyses, production of tables, 
listings and figures. This section outlines the planned statistical analysis of the primary endpoint 
and the planned statistical analyses for the secondary endpoints. All analyses and further 
description of the statistical methodology for primary as well as secondary endpoints will be

Operating Characteristics 
The operating characteristics and associated power are estimated for different dose-response 
scenarios by computer simulations using the Fixed and Adaptive Clinical Trial Simulator (FACTS) 
version 5.6. The five sigmoidal dose-response profiles that were used to simulate trial data are 
illustrated in Figure 9-1. Further details on the dose-response model and the associated primary 
analysis are given in Section 9.7.2 and Appendix 2.

The longitudinal data profile used in the simulations is based on pooled data from desmopressin 
clinical trials FE 992026 CS40 and FE 992026 CS41 (planned treatment group). The following 
estimates and assumptions were used: 
• 
Dose-response standard deviation 𝜎= 0.95 voids 
• 
A between to total variance (σ2) ratio of 0.90 and a true underlying σ of 0.95 
• 
Response fractions of 0.8142, 0.9328 and 0.9874 at Weeks 1, 4 and 8, respectively, as 
compared to the averaged dose-response at Week 12 
• 
Variance fractions of 0.8481, 0.8329 and 0.8900 at Weeks 1, 4 and 8, respectively, as 
compared to the averaged dose-response at Week 12 
Further design specifications were: 
• 
During the initial 17 weeks the recruitment rate will increase linearly from 0 to 8.2 subjects 
per week 
• 
After 17 weeks, when all trial sites have been initiated, the recruitment rate is assumed to 
remain constant at 8.2 subjects per week 
• 
Constant dropout rate of 15% during the randomised treatment period 
• 
First interim analysis when 125 subjects are randomised, thereafter interim analyses every 
8 weeks  
• 
Up to the first interim analysis the allocation ratio is 2:2:1 for placebo, 500 µg FE 201836 
and desmopressin 
• 
After the first interim analysis the allocation ratios are 2:7:1, for placebo, 50-500 µg 
FE 201836 and desmopressin  
o Subjects randomised to FE 201836 will be dynamically allotted to 
50 µg FE 201836, 100 µg FE 201836, 150 µg FE 201836, 250 µg FE 201836, 
350 µg FE 201836 or 500 µg FE 201836 using response-adaptive allocation as 
outlined in Section 9.11. 
• 
Maximum of 300 randomised subjects 
These settings were shared for all treatment groups. The average number of subjects and 
probabilities for futility and success are presented in Table 9-1.

For each dose-response scenario, 1,000 trials were simulated in order to estimate the operating 
characteristics presented in Table 9-1. The simulations under the null-hypothesis (no effect) 
demonstrate that assuming a maximum reduction versus placebo of 0.5 voids, the power 
(probability of success) reaches approximately 85 to 90%, while the probability of making a false 
positive conclusion is 3.0%. 
9.2 
Protocol Deviations 
Protocol deviations will be rated as either minor or major. Protocol deviations deemed to impact the 
primary endpoint and possibly affect the conclusions of the trial will be rated as major. Major 
protocol deviations will lead to exclusion of data from the Per Protocol (PP) analysis set 
(Section 9.3.5). Data up to the point where the violation occurs will be used in the evaluations.  
Major protocol deviations include, but are not restricted to, the following: 
• 
<2 nocturnal voids (average over 3 diaries) prior to Visit 2 or Visit 4 
• 
NPi ≤33% prior to Visit 2 
• 
<20% decrease in nocturnal diuresis rate (mL/min) from during active run-in (Visit 2 to 
Visit 3) 
• 
Maximum voided volume <200 mL prior to Visit 2 
• 
Actual treatment not in accordance with randomised treatment 
• 
Significant non-compliant treatment administration and e-Diary completion  
Serious unforeseen deviations deemed to impact the primary endpoint of the trial may additionally 
be rated as major protocol deviations by the sponsor on the basis of a blinded review of data before 
declaration of clean-file and lock of database. The list of major protocol deviations will be detailed 
and documented in the clean file document prior to database release to the trial statistician.

For endpoints obtained in the e-Diary prior to a visit, the 3-day e-Diary data will be averaged and 
interpreted as the observation of the endpoint in question. 
If nothing else is stated the Bayesian dose-response analyses are conducted with respect to the time-
averaged treatment effect. The posterior means estimates, 95% credibility interval of the estimates 
and posterior probabilities of quantities of interest will be reported.  
Frequentist inferences will rely on the appropriate choice of model and report p-values 
corresponding to the statistical test of the hypothesis of “equal effect” against the alternative of 
“different effect”. The level of significance is set at 5% (two-sided).  
Treatment comparison refers to the pair-wise comparison between active doses and placebo. There 
are no planned adjustments for multiplicity when pair-wise testing any active dose of FE 201836 
versus placebo. Desmopressin is included as a benchmark treatment only. None of the primary, 
secondary or explorative analyses will include desmopressin. Explorative benchmarking analyses 
are furher described in Section 9.8. 
9.7.2 
Primary Analysis 
The objectives of the primary analysis are to establish Proof-of-Concept of FE 201836 and to 
estimate the dose-response profile of FE 201836. The dose-response is the average reduction from 
baseline in nocturnal voids during the randomised period. Proof-of-concept will be evaluated by the 
posterior probability that FE 201836 has superior efficacy as compared to placebo. Similarly, 
interim analysis futility criteria will be evaluated by pre-defined quantities of interest.  
This section provides a brief background on the statistical Bayesian model that is utilised.  
9.7.2.1 
Statistical Dose-Response Model  
Let 𝑥𝑡,𝑖 denote the observed cross-sectional change from baseline in nocturnal voids (averaged 
across three consecutive nights) and let 𝑦𝑡,𝑖 denote the time-averaged change from baseline for 
subject 𝑖 up to time 𝑡: 
𝑦𝑡,𝑖=
∑
𝑥𝑘,𝑖 
𝑡
𝑘=1
𝑡
, 𝑡= 1,2,3,4, 
where 𝑡 denotes the nominal post-baseline time-point reflecting data observed at Weeks 1, 4, 8 
and 12 (Visits 5, 6, 7 and 8, respectively). The final endpoint, 𝑦4,𝑖, is modelled as being an 
observation of 𝑌4,𝑖~𝑁(𝜇𝑑,𝑖,𝜎2) where the dose-response at dose 𝑑 for subject 𝑖 is adjusted for the 
number of baseline voids (𝑥0,𝑖) and assumed to follow a sigmoidal model: 
𝜇𝑑,𝑖= 𝛽𝑥0,𝑖+ 𝛼1 +
(𝛼2−𝛼1)𝑑𝛼4
𝑑𝛼4+𝛼3𝑎4 = 𝛽𝑥0,𝑖+ 𝜇𝑑,

and 𝜎2 represents the (total error) variance of the dose-response. The interpretation of the 
parameters are: 𝛼1 is the placebo response; 𝛼2 is the maximum response; 𝛼3 is the dose (ED50) at 
which 50% of the maximum effect is obtained; 𝛼4 is the slope parameter.  
The longitudinal aspect of the average change from baseline is captured by the following model: 
𝑌𝑡,𝑖~𝑁(𝑒𝛾𝑡(𝜇𝑑,𝑖+ 𝛿𝑖),𝜆𝑡
2), 
where the per-subject offset from the mean dose-response is 𝛿𝑖~𝑁(0, 𝜏2) and 𝜆𝑡
2 represents the 
within subject variance. The model is constrained such that 𝛼4 = 0 and the intermediate values of 𝑦. 
can thus be thought of as being fractions of final value.  
Missing data (missing due to drop-out or final visit has not occurred yet) will be imputed using the 
longitudinal model, assuming missing at random. This implies that also data from subjects who 
have not yet been observed at Week 12 are used in the primary efficacy analysis, as described in 
Appendix 2. 
All parameters in the models are given sufficiently non-informative prior distributions as specified 
in Appendix 2. By application of Bayes’ theorem and Markov chain Monte Carlo sampling 
techniques the posterior probabilities (or the quantities of interest) given in Table 9-2 can be 
estimated.

Secondary and Explorative Analyses 
The following main categories of inferential analyses will be performed for the secondary 
endpoints: 
• 
Bayesian estimation of the Sigmoidal dose-response curve will follow the analysis 
described in Section 9.7.2.3. Prior distributions for primary analysis are specified in 
Appendix 2, while prior distributions for secondary analyses will be specified in the SAP. 
The dose-response model for the 50% responder rates will also be further detailed in the 
SAP. 
• 
Continuous treatment effects at a certain visit will be analysed using SAS PROC MIXED 
assuming a repeated measures ANCOVA. (A non-parametric dose-response curve is 
assumed.) The changes from baseline per visit will be regressed upon the baseline 
observation as covariate and treatment, visit and treatment-by-visit interaction as factors. An 
unstructured covariance structure will be used for the random subject effect. Least square 
mean estimates of the changes from baseline and the treatment contrasts (with associated 
95% confidence intervals) versus placebo will be tabulated and the changes from baseline 
will be graphically illustrated. Should only one post-baseline visit be obtained for an 
endpoint, an ANCOVA will be performed without the visit and treatment-by-visit 
interaction terms. 
• 
Correlation between endpoints will be reported using Pearson correlation coefficients and 
partial correlation where applicable. 
• 
Binary endpoints such as “responder status” at a certain visit will be analysed using SAS 
PROC GENMOD with the logit as link function for the responder probability. An 
unstructured covariance matrix will be assumed for the repeated responder status which will 
be adjusted for baseline value as covariate and treatment, visit and treatment-by-visit 
interaction as factors. (Associated with e.g., responder analysis in terms of reduction in 
number of voids, cumulative distritubtion function plots of percentage change from baseline 
by treatment may be produced.)  
Table 9-4 presents the planned analyses. 
Illustration of the therapeutic window is described separately in Section 9.7.3.1 and safety related 
endpoints are further described in Section 9.10. 
Explorative gender analyses are planned for all endpoints. For these the following are noted: 
• 
Estimates of the gender specific dose-response during 12 weeks of treatment will follow the 
analysis described in Section 9.7.2.3 by conducting separate analysis for each gender. 
Possible differences between the gender specific models will be investigated. 
• 
Regression models will include gender and gender-by-treatment as factors. (Possible 
differences between the treatment effects on gender will be evaluated by the interaction term 
gender-by-treatment.)  
Correlation analyses will be done separately for each gender.

desmopressin. Tables and figures will be produced as appropriate. This analysis will also be 
repeated by gender

Safety 
9.10.1 
General Considerations 
Safety analyses with respect to the enrichment period will be based on the Safety Analysis Set 
defined for the enrichment period, while analysis with respect to the randomised period will be 
performed using the safety analysis set. 
Safety will be assessed by analysis of adverse events, vital signs, clinical chemistry, haematology, 
urinalysis and physical examination. 
Missing values will be treated as missing, except for causality, intensity, seriousness and outcome 
of adverse events. A worst-case approach will be used: if causality is missing, the adverse event 
will be regarded as related to the IMP; if the intensity of an adverse event is missing, the adverse 
event will be regarded as severe; if seriousness is missing the adverse event will be regarded as 
serious; if onset date is missing it will be assumed to be the first day of dosing; if outcome is 
missing and no date of outcome is present the outcome is regarded as ‘ongoing’. 
Data will be presented in summary tables and listings. Categorical data will be summarised by 
treatment group using the number and percentage of subjects in each category. For calculation of 
percentages, the denominator will be the total number of subjects in the respective treatment group

Adverse Events 
Adverse events will be summarised overall and tabulated by SOC and preferred term using 
MedDRA. The version of MedDRA will be documented. The total number of subjects reporting an 
adverse event, the percentage of subjects (%) with an adverse event and the number of events 
reported will be presented.

Adverse Events of Special Interest: Hyponatraemia Episodes 
Observed serum sodium levels and the change from baseline will be tabulated by (planned) visit 
and treatment group. Similar tables will be produced for both trial periods (enrichment and 
randomised). 
The prevalence of worst-case hyponatraemic episodes, as defined in Table 9-6 will be presented by 
treatment group and visit for the randomised treatment period.  
During the enrichment period (active run-in and washout) hyponatraemic episodes will be 
presented in the same ranges, but here the definition requires only one observation below the upper 
limit (≥135 mmol/L) to yield a hyponatraemic episode.

9.10.3.1 
Hyponatraemia during the Randomised Treatment Period 
These analyses are restricted to the Safety Analysis Set only. 
The incidence of the post-baseline worst-case hyponataemia episode for each subject will be 
summarised as described in Table 9-6.  
Graphs will plot the serum sodium levels by treatment group and the profiles of the subjects who at 
any time (Visit 1 and onwards) have a serum sodium level <135 mmol/L will be highlighted.  
Kaplan-Meier plots of time from randomisation (Visit 4) to hyponatraemic serum sodium levels 
(<135, <130 and ≤125 mmol/L) per treatment group will be produced. For the thresholds <135 and 
<130 mmol/L at least 3 and 2 consecutive observations, respectively, have to be below the 
threshold to yield a hyponatraemic event (Table 9-6). For both cases the time is from randomisation 
until first observation below the respective limit that counts. 
The associated relative hazards of treatment and gender will be analysed using Cox proportional 
hazards model adjusting for baseline serum sodium and age (<65, ≥65 years). Possible 
heterogeneity between the genders in the relative treatment hazards will be explored by the 
inclusion of a treatment-by-gender interaction term. 
9.10.4 
Safety Laboratory Variables 
Laboratory test results and their change from baseline to end-of-trial will be summarised by 
treatment group for the Safety Analysis Set. The number and percent of subjects with clinically 
significant laboratory abnormalities will be presented. Shift tables from baseline to end-of-trial visit 
(categorised as low, normal and high) will be presented by treatment group. 
9.11 
Interim Analyses 
Two kinds of interim analyses are planned in the trial. One is safety-oriented and concerns the 
monitoring of the serum sodium levels observed during the active run-in period. As described in

Section 3.4, a DMC will be established for the trial and make recommendations based on review of 
safety data, e.g., increased rates of clinically significant serums sodium levels observed during the 
active run-in period, as described in Section 9.11.1. The second kind concerns the pre-planned 
efficacy analyses upon which the trial may be stopped due to futility, or allocation probabilities to 
FE201836 doses may be adjusted based on estimated dose-response curve, as described in 
Section 9.11.2. 
9.11.1 
Serum Sodium Monitoring during the Active Run-In Period 
The risk of subjects developing hyponatraemia will be mitigated by a serum sodium monitoring 
plan (Section 7.1.3.1), including a 1-week active run-in period to identify subjects at increased risk 
for developing acute hyponatraemia prior to randomisation. If the incidence of serum sodium levels 
<130 mmol/L is statistically significantly >10% during the active run-in, the DMC (Section 3.4) 
will be notified and further action will be discussed, e.g., the DMC may recommend that the highest 
dose of FE 201836 may be replaced by a lower dose. 
The number of cases of serum sodium levels <130 mmol/L resulting in an estimated rate that is 
statistically significantly >10% depends on the number of subjects who have completed the active 
run-in, examples are presented in Table 9-7.

Thus, the present trial has been designed with the option to decrease the maximal dose of 
FE 201836 from 500 µg to 350 µg if recommended by the DMC. If this decision is made, 
randomisation to the 500 µg FE 201836 treatment group will be closed, the trial will continue with 
350 µg FE 201836 as the highest dose for the active run-in and the highest dose of FE 201836 that 
any subject can be randomised to. In the case where subjects have already been randomised to 
500 µg FE 201836 and have not completed the trial the DMC will recommend whether or not, these 
subjects may be permitted to remain on 500 µg FE 201836 treatment for the remainder of the trial. 
If the decision to close randomisation to 500 µg FE 201836 occurs prior to the first interim analysis 
(when the first 125 subjects are randomised) the remaining subjects will be randomised to the 
following treatment groups: placebo, desmopressin (25 µg for females and 50 µg for males) or 
350 µg FE 201836. After the interim analysis subjects may be randomised to one of 7 treatment 
groups: placebo, 50 µg FE 201836, 100 µg FE 201836, 150 µg FE 201836, 250 µg FE 201836, 
350 µg FE 201836, or desmopressin (25 µg for females and 50 µg for males).

The dose-response model will be fitted across all doses, i.e., 0-500 µg, but inference will be made 
only on the doses that remain open to randomisation e.g., 0-350 µg. That is, the MED and ED85 
doses and the inferences with regards to proof-of-concept and futility will be limited to the dose 
range (i.e., with a maximum dose of 350 µg FE 201836).  
9.11.2 
Interim Efficacy Analyses 
The planned interim analyses will be conducted by an internal DMC (Section 3.4) according to a 
separate DMC charter, which will be established before the first interim analysis. The interim 
analyses will use unblinded efficacy data to infer whether to stop early for futility or to continue the 
trial as planned.  
At the first interim analysis the trial may be stopped due to futility if there is a low probability (less 
than 10%) that 500 µg FE 201836 is at least 0.3 voids more efficacious than placebo:  
Pr(𝜇𝑀𝐴𝑋−𝜇𝑃𝑙𝑏< −0.3) < 10%. 
Up to the first interim analysis (conducted when 125 subjects have been randomised) the allocation 
ratio is 2:2:1 for placebo, 500 µg FE 201836 and desmopressin. Should the trial continue, the 
allocation ratios will be changed to 2:7:1, where all doses of FE 201836 (50-500 µg) are opened for 
response-adaptive allocation. The randomisation probabilities for each dose of FE 201836 will be 
proportional to the average of I(dose is MED) and I(dose is ED85), where I(target) is the square root 
of the probability that “dose is target” scaled by the standard error at that dose. 
The remaining interim analyses are planned to occur every 8 weeks as depicted in the decision 
tree (Figure 9-2).  
These interim analyses will re-iterate the (overall) futility criteria at the 5% threshold: 
Pr(𝜇𝑀𝐴𝑋−𝜇𝑃𝑙𝑏< −0.3) < 5% (see Table 9-2 for interpretation). 
At the final analysis (when all subjects have had their 12-week visit, or discontinued prior to this 
visit) Proof-of-Concept is established if Pr(𝜇𝑀𝐴𝑋< 𝜇𝑃𝑙𝑏) > 97.5%.

DATA HANDLING 
10.1 
Source Data and Source Documents 
Source Data – International Conference on Harmonisation (ICH) Definition 
Source data are defined as all information in original records and certified copies of original records 
of clinical findings, observations, or other activities in a clinical trial necessary for the 
reconstruction and evaluation of the trial. Source data are contained in source documents (original 
records or certified copies). 
Source Documents - ICH Definition 
Source documents are defined as original documents, data and records (e.g., hospital records, 
clinical and office charts, laboratory notes, memoranda, subject diaries or evaluation checklists, 
pharmacy dispensing records, recorded data from automated instruments, copies or transcriptions 
certified after verification as being accurate copies, microfiches, photographic negatives, microfilm 
or magnetic media, x-rays, subject files and records kept at the pharmacy, at the laboratories and at 
medico-technical departments involved in the clinical trial). 
Trial-specific Source Data Requirements - The Sponsor 
No specific protocol data can be recorded directly in the e-CRF without a prior written or electronic 
record. The data entered in the eCRF that are transcribed from source documents must be consistent 
with the source documents or the discrepancies must be explained. The e-Diary data is part of a 
process where the subject uses the e-Diary to transmit data to the service provider’s database, hence 
the service provider’s database is considered to be the source data. The investigator may need to 
request previous medical records or transfer records, current medical records must also be 
available.  
For each subject enrolled, the investigator must document in the subject’s medical record, that the 
subject participates in this trial and at least the following information must be recorded: 
• 
Documentation of signed and dated informed consent 
• 
Subject’s name and date of birth 
• 
Confirmation of participation in the trial (trial identification, screening/randomisation 
[subject] number) 
• 
Eligibility of participation in the trial (inclusion/exclusion) 
• 
Relevant medical history 
• 
Nocturia medical history or subject-reported nocturia symptoms  
• 
Visit Dates 
• 
Results of any examinations/tests and assessment performed 
• 
Details of any concomitant medication/therapy

10.2 
Electronic Case Report Form 
An eCRF system provided by 
 an independent third-party Contract Research 
Organisation (CRO) will be used for data capture. The system is validated and access at all levels to 
the system is granted/revoked following sponsor and vendor procedures, in accordance with 
regulatory and system requirements. 
Trial data should be entered into the eCRF in a timely manner preferably within 3 working days 
after the subject visit.  
The investigator will approve/authorise the eCRF entries for each subject with an electronic 
signature which is equivalent to a handwritten signature.  
The eCRF system and the database will be hosted at 
. After the trial database is 
declared clean and released to the statistician, a final copy of the database will be stored at the 
sponsor. The investigator will also receive a copy of the trial site’s final and locked data (including 
audit trail, electronic signature and queries) as write-protected PDF-files produced by 
 
. The PDF-files will be stored electronically and will be provided by 
 to the 
investigator before access to the eCRF is revoked. 
Entry errors occurring in the eCRF will be corrected electronically. Such corrections/modifications 
will be automatically tracked by an audit trail detailing the date and time of the correction, the name 
of the person making the correction and the reason for the correction. 
10.3 
Use of Patient Reported Outcomes 
The PRO questionnaires to be used in the trial are described in Section 7.1.1.3.

All PROs will be captured in the 3-day e-Diary and completed by the subject, either at the trial site 
(ISI, Bother) or at home just prior to the trial visit (PGI-I, PGI-S), as outlined in Figure 3-2 and 
Figure 3-3. For PROs completed at home, subjects will be reminded in due time. The 3-day 
e-Diary, including the PROs will be reviewed for completeness (via the web-portal) by the trial site 
personnel throughout the trial (Section 6). 
In case of missing ISI and Bother assessments, the reason(s) should be recorded by the trial 
personnel in the eCRF, e.g., subject refusal, lack of time from subject or functional limitation from 
subject to complete the questionnaire. Handling of missing assessments and missing data will be 
detailed in the SAP. 
10.3.1 
Validation of the Nocturia Impact Diary 
10.3.1.1 
Psychometric Validation 
In connection with this trial, the NI Diary will be further tested and validated through anchor-based 
analyses including the PRO questionnaires PGI-I and PGI-S (Section 7.1.1.3.1) and subjects’ 
perception of change in NI Diary Total Score as captured in exit interviews (Section 10.3.1.2). 
Details of these analyses are described in a separate PAP. The order of these three e-Diary 
assessments, all completed at home, should therefore be NI Diary first, PGI-S second and PGI-I 
last, as described in Section 7.1.1.3. 
10.3.1.2 
Validation through Exit Interviews 
A sample of subjects (from trial sites in the USA) who have completed the trial will be invited to 
participate in an exit interview within 14 days of attending the end-of-trial visit (Visit 8). Signed 
informed consent must have been obtained through the ICF for the trial, as appropriate, before 
participation in the exit interview. 
The exact size of the sample will depend on when saturation has been reached. The subjects 
included will be proportionate to the clinical trial sample distribution with respect to demographic 
and clinical characteristics. The investigator at the trial site will be asked to complete a Case Report 
Form that includes specific requirements for recruiting subjects to ensure the correct mix of 
subjects. 
The exit interview is designed to examine the impact of living with nocturia and to assess what a 
meaningful positive change would be from the subject’s perspective in terms of this impact. In the 
exit interviews, subjects’ ratings and perceptions of changes will be collected using qualitative and 
quantitative methods. These data will be used to aid in understanding what is, from a subject’s 
perspective, a meaningful change threshold for indicating positive improvement in the impact of 
nocturia on a subject’s life, as measured by the NI Diary. 
A detailed description of the exit interview is provided in the Exit Interview Protocol, enclosed in 
Appendix 1. 
All exit interviews will be conducted over the telephone by a trained interviewer from
.

MONITORING PROCEDURES 
11.1 
Periodic Monitoring 
The monitor will contact and visit the investigator periodically to ensure adherence to the protocol, 
International Conference of Harmonisation-Good Clinical Practice (ICH-GCP), standard operating 
procedures and applicable regulatory requirements, maintenance of trial-related source records, 
completeness, accuracy and verifiability of eCRF entries compared to source data, verification of 
drug accountability and compliance to safety reporting instructions.  
The investigator will permit the monitor direct access to all source data, including electronic 
medical records and/or documents in order to facilitate data verification. The investigator will co-
operate with the monitor to ensure that any discrepancies that may be identified are resolved. The 
investigator is expected to be able to meet the monitor during these visits.  
Risk based monitoring will be applied for this trial. The frequency of the on-site monitoring visits 
will be adapted depending on the risk level of the site and workload. Site risk is based on multiple 
factors including, but not limited to, the quantity of data generated, quality of the source 
documents, unreported adverse events or SAEs and number of protocol deviations. 
The risk-based monitoring and adaptive monitoring strategy, source data verification process and 
definition of key variables to be monitored will be described in detail in the Monitoring Plan for the 
trial.  
11.2 
Audit and Inspection 
The investigator will make all the trial-related source data and records available at any time to 
quality assurance auditor(s) mandated by the sponsor, or to domestic/foreign regulatory inspectors 
or representatives from IECs/IRBs/REBs who may audit/inspect the trial. 
The main purposes of an audit or inspection are to assess compliance with the trial protocol and the 
principles of ICH-GCP including the Declaration of Helsinki (World Medical Association 
Declaration of Helsinki, 2013) and all other relevant regulations. 
The subjects must be informed by the investigator and in the Informed Consent Documents that 
authorised sponsor representatives and representatives from regulatory authorities and 
IECs/IRBs/REBs may wish to inspect their medical records. During audits/inspections the 
auditors/inspectors may copy relevant parts of the medical records. No personal identification apart 
from the screening/randomisation number will appear on these copies. 
The investigator should notify the sponsor without any delay of any inspection by a regulatory 
authority or IEC/IRB/REB.

11.3 
Confidentiality of Subject Data 
The investigator will ensure that the confidentiality of the subjects’ data will be preserved. In the 
eCRF or any other documents submitted to the sponsor, the subjects will not be identified by their 
names, but by an identification system, which consists of an assigned number in the trial. 
Documents that are not for submission to the sponsor, e.g., the confidential subject identification 
code and the signed Informed Consent Documents, will be maintained by the investigator in strict 
confidence. 
11.4 
Centralised Statistical Monitoring 
Centralised statistical monitoring will be conducted on (but not limited to) the following key 
aspects of the trial: 
• 
The incidence rate of hyponatraemia throughout the trial 
• 
Key inclusion criteria (number of voids, voided volumes, NI Diary and Bother)  
• 
The number of voids and NI Diary data as collected in the e-Diary throughout the trial 
• 
Monitoring at trial site level will focus on the accumulated trial site data and comparisons 
across trial sites will be performed

CHANGES IN THE CONDUCT OF THE TRIAL 
12.1 
Protocol Amendments 
Any change to this protocol will be documented in a protocol amendment, issued by the sponsor 
and agreed upon by the investigator and the sponsor prior to its implementation.  
Amendments may be submitted for consideration to the approving IECs/IRBs/REBs and regulatory 
authorities, in accordance with local regulations. Changes to the protocol to eliminate immediate 
hazards to trial subjects may be implemented prior to IECs/IRBs/REBs approval/favourable 
opinion. 
12.2 
Deviations from the Protocol 
Deviations from the protocol should not occur. If deviations occur, the investigator must inform the 
monitor and the implications of the deviation must be reviewed and discussed. Any deviation must 
be documented, either as answer to a query in the eCRF, in a protocol deviation report or a 
combination of both. A log of protocol deviation reports will be maintained by the sponsor. 
Deviation reports and supporting documentation must be kept in the Investigator’s File and in the 
Trial Master File. 
12.3 
Premature Trial Termination 
Both the investigator (with regard to his/her participation) and the sponsor reserve the right to 
terminate the trial at any time. Should this become necessary, the procedures will be agreed upon 
after consultation between the two parties. In terminating the trial, the sponsor and the investigator 
will ensure that adequate consideration is given to the protection of the best interests of the 
subjects. Regulatory authorities and IECs/IRBs/REBs will be informed. 
In addition, the sponsor reserves the right to terminate the participation of individual trial sites. 
Conditions that may warrant termination include, but are not limited to, insufficient adherence to 
protocol requirements and failure to enter subjects at an acceptable rate.

The data and information collected during this trial will be reported in a clinical trial report 
prepared by the sponsor and submitted for comments and signature to the signatory investigators. 
13.2 
Confidentiality and Ownership of Trial Data 
Any confidential information relating to the IMP or the trial, including any data and results from 
the trial will be the exclusive property of the sponsor. The investigator and any other persons 
involved in the trial will protect the confidentiality of this proprietary information belonging to the 
sponsor. 
13.3 
Publications and Public Disclosure 
13.3.1 
Publication Policy 
At the end of the trial, one or more manuscripts for joint publication may be prepared in 
collaboration between the investigator(s) offered authorship and the sponsor. In a multi-site trial 
based on the collaboration of many sites, any publication of results must acknowledge all sites. 
Results from multi-site trials must be reported in entirety in a responsible and coherent manner and 
results from subsets should not be published in advance or without clear reference to the primary 
publication of the entire trial. 
Authorship is granted based on the International Committee of Medical Journal Editors (ICMJE) 
criteria (see current official version: http://www.icmje.org). The total number of authors is based on 
the guideline from the relevant journal or congress. In the event of any disagreement in the content 
of a publication, both the investigator’s and the sponsor’s opinion will be fairly and sufficiently 
represented in the publication. 
Any external CRO or laboratory involved in the conduct of this trial has no publication rights 
regarding this trial. 
If the investigator wishes to independently publish/present any results from the trial, the draft 
manuscript/presentation must be submitted in writing to the sponsor for comments prior to 
submission. Comments will be given within 4 weeks from receipt of the draft manuscript. This 
statement does not give the sponsor any editorial rights over the content of a publication, other than 
to restrict the disclosure of the sponsor’s intellectual property. If the matter considered for 
publication is deemed patentable by the sponsor, scientific publication will not be allowed until 
after a filed patent application is published. Under such conditions the publication will be modified 
or delayed at the investigator’s discretion, to allow sufficient time for the sponsor to seek patent 
protection of the invention.

Public Disclosure Policy  
ICMJE member journals have adopted a trials-registration policy as a condition for publication. 
This policy requires that all clinical trials be registered in a public, clinical trials registry. Thus, it is 
the responsibility of the sponsor to register the trial in an appropriate public registry, i.e. 
www.ClinicalTrials.gov; a website maintained by the National Library of Medicine (NLM) at the 
U.S. National Institutes of Health (NIH). The trial will also be made publicly available at the 
European Union (EU) Clinical Trials Register at www.clinicaltrialsregister.eu. Trial registration 
may occur in other registries in accordance with local regulatory requirements. A summary of the 
trial results is made publicly available in accordance with applicable regulatory requirements.

recruitment. The IEC/IRB/REB will review the subject information sheet and the ICF, their updates 
(if any) and any written materials given to the subjects. A list of all IECs/IRBs/REBs to which the 
protocol has been submitted and the name of the committee chairmen will be included in the 
clinical trial report. 
14.2 
Regulatory Authorities Approval 
The regulatory permission to perform the trial will be obtained in accordance with applicable 
regulatory requirements. All ethical and regulatory approvals must be available before a subject is 
exposed to any trial-related procedure, including screening tests for eligibility. 
14.3 
End-of-Trial and End-of-Trial Notification 
The end of this trial is defined as the date of the last visit (Visit 8) of the last subject undergoing the 
trial. An end-of-trial declaration will be prepared when the trial has ended and will be submitted to 
the IECs/IRBs/REBs and regulatory authorities. 
14.4 
Ethical Conduct of the Trial 
This trial will be conducted in accordance with the ethical principles that have their origins in the 
Declaration of Helsinki (World Medical Association Declaration of Helsinki, 2013), in compliance 
with the approved protocol, ICH-GCP and applicable regulatory requirements. 
14.5 
Subject Information and Consent 
The investigator (or the person delegated by the investigator) will obtain a freely given written 
consent from each subject after an appropriate explanation of the aims, methods, sources of 
funding, any possible conflicts of interest, anticipated benefits, potential risks of the trial and the 
discomfort it may entail, post-trial provisions and any other aspects of the trial which are relevant to 
the subject’s decision to participate. The trial subject must be given ample time to consider 
participation in the trial, before the consent is obtained. The Informed Consent Documents must be 
signed and dated by the subject and the investigator who has provided information to the subject 
regarding the trial before the subject is exposed to any trial-related procedure, including screening 
tests for eligibility. Subjects must be given the option of being informed about the general outcome 
and the results of the trial. 
The investigator (or the person delegated by the investigator) will explain that the subject is 
completely free to refuse to enter the trial or to withdraw from it at any time, without any 
consequences for his/her further care and without the need to justify his/her decision. 
The subject will receive a copy of the subject information and his/her signed ICF.

ARCHIVING 
16.1 
Investigator File 
The investigator is responsible for maintaining all the records, which enable the conduct of the trial 
at the site to be fully understood, in compliance with ICH-GCP. The trial documentation including 
all the relevant correspondence should be kept by the investigator for at least 15 years after the 
completion or discontinuation of the trial, if no further instructions are given by the sponsor. 
The investigator is responsible for the completion and maintenance of the confidential subject 
identification code which provides the sole link between named subject source records and 
anonymous eCRF data for the sponsor. The investigator must arrange for the retention of this 
subject identification log and signed informed consent documents for at least 15 years after the 
completion or discontinuation of the trial. 
No trial site document may be destroyed without prior written agreement between the investigator 
and the sponsor. Should the investigator elect to assign the trial documents to another party, or 
move them to another location, the sponsor must be notified in advance. If the investigator retires 
and the documents can no longer be archived by the site, the sponsor can arrange having the 
Investigator File archived at an external archive. 
16.2 
Trial Master File 
The sponsor will archive the Trial Master File in accordance with ICH-GCP and applicable 
regulatory requirements.
