Synopsis
Rationale:
The prevalence of obesity has reached epidemic proportions in most countries around the world and 
the prevalence is still increasing at an alarming rate1-7. The medical and societal impacts are 
considerable and obesity is one of the most significant public health challenges worldwide1-7.
Obesity is associated with increased risk of a variety of comorbidities, affects physical and mental 
health and reduces health related quality of life8, 9.
Pharmacotherapy may serve as a valuable adjunct to lifestyle intervention for individuals with 
obesity in order to achieve and sustain a clinically relevant weight loss, to improve comorbid 
conditions and to facilitate a healthier lifestyle. Few anti-obesity medications are currently available 
and there is a need for more effective and safe therapeutic options for treatment of obesity. The 
present trial is a 68-week trial designed to show reduction in body weight and compare the effect 
and safety of semaglutide subcutaneous (s.c.) 2.4 mg once-weekly versus semaglutide placebo as an 
adjunct to a reduced-calorie diet and increased physical activity in subjects with overweight or 
obesity.
Objectives and endpoints:
Primary objective
To compare the effect of semaglutide s.c. 2.4 mg once-weekly versus semaglutide placebo as an 
adjunct to a reduced-calorie diet and increased physical activity in subjects with overweight or 
obesity on body weight
Key secondary objectives
To compare the effect of semaglutide s.c. 2.4 mg once-weekly versus semaglutide placebo as an 
adjunct to a reduced-calorie diet and increased physical activity in subjects with overweight or 
obesity on:
!
Cardiovascular risk factors 
!
Clinical Outcome Assessments (COAs)
To compare the safety and tolerability of semaglutide s.c. 2.4 mg once-weekly versus semaglutide 
placebo as an adjunct to a reduced-calorie diet and increased physical activity in subjects with 
overweight or obesity
Primary estimand
The estimand will quantify the average treatment effect of semaglutide relative to semaglutide 
placebo after 68 weeks, as an adjunct to a reduced-calorie diet and increased physical activity, in all 
randomised subjects regardless of adherence to treatment and regardless of starting rescue

interventions (weight management drugs or bariatric surgery) (“effectiveness”/“treatment policy” 
estimand). The estimand will cover all effect-related objectives.
Primary endpoint
The primary endpoints addressing the primary objective:
!
Change from baseline at week 0 to week 68 in body weight (%)
!
Subjects who after 68 weeks achieve (yes/no): 
!
Body weight reduction ≥ 5% from baseline at week 0
Confirmatory secondary endpoints
!
Subjects who after 68 weeks achieve (yes/no):
!
Body weight reduction ≥ 10% from baseline at week 0
!
Body weight reduction ≥ 15% from baseline at week 0
!
Change from baseline at week 0 to week 68 in:
!
Waist circumference (cm)
!
Systolic blood pressure (mmHg)
!
Physical functioning score (SF-36)
!
Physical function domain (5-items) score (IWQoL-Lite for CT)
Overall design:
This is a 68-week, randomised, double-blind, placebo-controlled, two-armed, parallel group, multi-
centre, multinational clinical trial comparing semaglutide s.c. 2.4 mg once-weekly with semaglutide 
placebo once-weekly in subjects with overweight or obesity.
Key inclusion criteria
!
Male or female, age ≥ 18 years at the time of signing informed consent
!
Body mass index (BMI) ≥ 30 kg/m2 or ≥ 27 kg/m2 with the presence of at least one of the 
following weight-related comorbidities (treated or untreated): hypertension, dyslipidaemia, 
obstructive sleep apnoea or cardiovascular disease 
!
History of at least one self-reported unsuccessful dietary effort to lose body weight
Key exclusion criteria
!
HbA1C ≥ 48 mmol/mol (6.5%) as measured by the central laboratory at screening 
!
A self-reported change in body weight > 5 kg (11 lbs) within 90 days before screening 
irrespective of medical records
Number of subjects:
Approximately 2294 subjects will be screened to achieve 1950 subjects randomly assigned to trial 
product.

Treatment groups and duration:
Eligible subjects fulfilling all randomisation criteria at visit 2 will be randomised in a 2:1 manner to 
receive either semaglutide s.c 2.4 mg once-weekly or semaglutide placebo once-weekly as an 
adjunct to a reduced-calorie diet and increased physical activity. 
The trial includes a screening visit to assess the subject’s eligibility followed by visits/phone 
contacts every 2nd week for the first 20 weeks. For the remaining maintenance period until end of 
treatment (week 68), visits/phone contacts will take place every 4th week. A follow-up visit (‘End of 
trial’) for safety assessments is scheduled 7 weeks after end of treatment to account for the exposure 
and the long half-life of semaglutide.
The following trial products will be supplied by Novo Nordisk A/S:
!
Semaglutide B 1.0 mg/mL PDS290 and semaglutide placebo, solution for injection, 3 mL 
PDS290 pre-filled pen-injector
!
Semaglutide B 3.0 mg/mL PDS290 and semaglutide placebo, solution for injection, 3 mL

Introduction
3.1
Trial rationale
The prevalence of obesity has reached epidemic proportions in most countries around the world and 
the prevalence is still increasing at an alarming rate1-7. The medical and societal impacts are 
considerable and obesity is one of the most significant public health challenges worldwide1-7.
Obesity is associated with increased risk of a variety of comorbidities including hyperglycaemia, 
type 2 diabetes (T2D), hypertension, dyslipidaemia, obstructive sleep apnoea, atherosclerosis, 
osteoarthritis, urinary incontinence, non-alcoholic steatohepatitis, cardiovascular diseases, certain 
types of cancer, and risk of early death10-24. Moreover, obesity adversely affects physical and mental 
health and reduces health related quality of life8, 9. Obesity is also associated with decreased 
cardiorespiratory fitness, which also increases the risk of cardiovascular diseases and all-cause 
mortality25.
The risk of obesity-related complications and comorbidities increases with increasing BMI, and a 
weight loss of 5−10 % has significant health benefits in terms of slowing progression to T2D26-29.
Furthermore, a weight loss of 5−10% improves many other obesity related comorbidities as well as 
physical symptoms and quality of life30-37. Finally, studies suggest a beneficial impact of weight 
loss on cardiovascular risk and mortality in both people with diabetes and obesity38-40.
Lifestyle intervention in the form of diet and exercise is first line treatment for obesity, but most 
people with obesity struggle to achieve and maintain their weight loss41-50. Surgical treatments offer 
an effective alternative for some people with severe obesity, but surgery carries a risk in connection 
with the procedure and is not without complications. Furthermore, surgery requires close follow-up 
of the individual which can be cumbersome and costly41-46, 51, 52. Pharmacotherapy may therefore 
serve as a valuable adjunct to lifestyle intervention for individuals with obesity in order to achieve 
and sustain a clinically relevant weight loss, to improve comorbid conditions and to facilitate a 
healthier lifestyle. Few anti-obesity medications are currently available and there is a need for more 
safe and effective therapeutic options for treatment of obesity, especially treatments that also target 
weight maintenance, prevention and treatment of comorbidities41-45, 53, 54.
3.2
Background
3.2.1
Semaglutide
Semaglutide is the next generation glucagon-like peptide -1 receptor agonist (GLP-1 RA) currently 
under development by Novo Nordisk for the treatment of weight management (NN9536). 
Semaglutide has been optimised resulting in a longer half-life of approximately 160 hours, making 
it suitable for once-weekly dosing55. GLP-1 RA is a physiological regulator of appetite and GLP-1
receptors are present in several areas of the brain involved in appetite regulation56.

A 52-week phase 2 dose-finding trial within weight management (NN9536-4153) has recently been 
completed. A total of 957 randomised subjects with obesity (without diabetes) were exposed to 
semaglutide (n=718), liraglutide 3.0 mg (n=103) or placebo (n=136). In this trial, an overall 
monotone dose-dependent weight loss was observed across the 5 semaglutide doses tested (0.05 to 
0.4 mg once-daily). The estimated weight loss at week 52 was 13.8 % at the highest dose tested (0.4 
mg once-daily) compared to the weight loss of 2.3% achieved by diet, exercise and placebo alone.57
Clinical58-62 and non-clinical data63 indicate that the body weight-reducing effect of semaglutide is 
mainly mediated by a reduced energy intake. No unexpected safety findings were identified and the 
tolerability and safety profile was overall consistent with previous findings in the T2D development 
programme and the GLP-1 RA class in general.
A comprehensive review of results from the non-clinical and clinical studies of semaglutide can be 
found in the current edition of the investigator’s brochure (IB)57 and any updates hereof.
3.2.2
Trial population 
The trial population will consist of subjects with obesity (BMI > 30 kg/m2) or with overweight 
(BMI > 27 kg/m2) and weight-related comorbidities. These subjects represent a clinically relevant 
population for pharmacotherapeutic weight management as they are at significant risk for weight-
related morbidities and mortality, and are likely to benefit from weight reduction. Information about 
weight-related comorbidities, including hypertension, dyslipidaemia, obstructive sleep apnoea or 
cardiovascular disease, will be collected systematically at screening by the investigators as part of 
the medical history.
Subjects with T2D are excluded from the trial. Subjects with overweight or obesity and T2D will be 
addressed in a dedicated trial.
First line treatment in weight management should always be lifestyle modification through a 
reduced-calorie diet and increased physical activity. Thus only subjects who have tried but failed a 
dietary weight loss intervention will be included in accordance with regulatory guidelines64, 65.
3.3
Benefit-risk assessment
3.3.1
Benefits
Subjects will be treated with a regimen anticipated to be better than or equal to the weight 
management they receive at the time of entry into the trial. Results from the phase 2 trial 
(NN9536-4153) demonstrated that semaglutide s.c. once-daily as an adjunct to a reduced-calorie 
diet and increased physical activity was effective for weight loss in subjects with obesity, while 
displaying a satisfactory tolerability profile. Overall, a monotone dose-dependent weight loss was 
observed across all tested doses of semaglutide (0.05 to 0.4 mg once-daily). The weight loss was 
11.55 percentage points larger for the 0.4 mg group compared with placebo. Weight loss was

accompanied by a consistent improvement in weight-related comorbidities, indicated by 
cardiovascular risk factors, lipid profile and glycaemic factors, as well as improvements in clinical 
outcome assessments.
In addition, it is expected that all subjects will benefit from participation through close contact with 
the trial site and counselling by a dietician or a similar qualified healthcare professional, all of 
which will most likely result in intensified weight management. 
3.3.2
Risks and precautions
The sections below describe identified and potential risks associated with semaglutide treatment. 
The identified/potential risks are based on findings in non-clinical studies and clinical trials with 
semaglutide as well as other GLP-1 RAs. For each of these risks, mitigating actions have been 
implemented to minimise the risks for subjects enrolled in this trial.
Identified risks
!
Gastrointestinal adverse events
!
Consistent with findings with other GLP-1 RAs, the most frequently reported adverse 
events (AE) in clinical trials with semaglutide were gastrointestinal AEs. A low starting 
dose and dose escalation steps will be implemented in the trial to mitigate the risk of 
gastrointestinal AEs.
!
Cholelithiasis
!
Events of cholelithiasis were the most frequently reported gallbladder events in the 
phase 2 weight management trial (NN9536-4153) and were in a few instances co-
reported with the event adjudication committee (EAC) confirmed acute pancreatitis. As 
a precaution, if cholelithiasis is suspected, appropriate clinical follow-up is to be 
initiated at the investigator’s discretion. 
!
Acute pancreatitis
!
Acute pancreatitis has been observed with the use of GLP-1 RA drug class. As a 
precaution, subjects with a history of chronic pancreatitis or recent acute pancreatitis
will not be enrolled in the trial. In addition, trial product should be discontinued in case 
of suspicion of acute pancreatitis in accordance to Section 8.1. 
Potential risks
!
Medullary thyroid cancer (MTC) (based on non-clinical data)
!
Expected proliferative thyroid C-cell changes were seen in the mouse and rat 
carcinogenicity studies after daily exposure to semaglutide for 2 years. No hyperplasia 
was observed in monkeys after 52 weeks exposure up to 13-fold above the clinical 
plasma exposure at 2.4 mg/week. In clinical trials with semaglutide, there have been no 
reports of MTC or clinically relevant changes in calcitonin levels. The C-cell changes in 
rodents are mediated by the GLP-1 receptor, which is not expressed in the normal

human thyroid. Accordingly, the risk of GLP-1 receptor-mediated C-cell changes in 
humans is considered to be low. However, as a precaution, exclusion and 
discontinuation criteria related to medical history of multiple endocrine neoplasia type 2 
(MEN2) or MTC and elevated plasma levels of calcitonin (biomarker for MTC) have 
been implemented in the trial. 
!
Pancreatic cancer 
!
There is currently no support from non-clinical studies, clinical trials or post-marketing 
data that GLP-1 RA based therapies increase the risk of pancreatic cancer, but pancreatic 
cancer has been classified as a potential class risk of GLP-1 RAs by European Medicines 
Agency. As a precaution, subjects with a history of malignant neoplasms within the past 
5 years prior to screening will be excluded from the trial. 
!
Allergic reactions
!
As is the case with all protein-based pharmaceuticals, subjects treated with semaglutide 
are at risk of developing immunogenic and allergic reactions. As a precaution, subjects 
with known or suspected hypersensitivity to semaglutide or related products will not be 
enrolled in this trial. 
Other risks
!
Pregnancy and fertility (based on non-clinical data)
!
Studies in animals have shown reproductive toxicity. There are limited data from the use 
of semaglutide in pregnant women. Therefore, semaglutide should not be used during 
pregnancy. Exclusion and discontinuation criteria related to pregnancy have been 
implemented in the trial.
3.3.3
Conclusion on benefit-risk profile
Necessary precautions have been implemented in the design and planned conduct of the trial in 
order to minimise the risks and inconveniences of participation in the trial. The safety profile for 
semaglutide generated from the clinical and non-clinical development programme has not revealed 
any safety issues that would prohibit administration of semaglutide s.c. 2.4 mg once-weekly. The 
results of the phase 2 trial (NN9536-4153) indicate that semaglutide will provide a clinically 
meaningful weight loss.
In conclusion, the potential risk to the subjects in this trial is considered low and outweighed by the 
anticipated benefits that semaglutide would provide subjects included in this trial.
More detailed information about the known and expected benefits and risks and reasonably 
expected adverse events of semaglutide s.c. may be found in the IB57 and any updates hereof.

Trial design
5.1
Overall design
This is a 68-week, randomised, double-blind, placebo-controlled, two-armed, parallel group, multi-
centre, multinational clinical trial comparing semaglutide s.c. 2.4 mg once-weekly with semaglutide 
placebo once-weekly in subjects with overweight or obesity.
The trial includes a screening visit to assess the subject’s eligibility followed by visits/phone 
contacts every 2nd week during dose escalation. From week 20, visits/phone contacts will take place 
every 4th week for the remaining maintenance period until end of treatment (week 68). A follow-up 
visit (‘End of trial’) for safety assessments is scheduled 7 weeks after end of treatment to account 
for the exposure and the long half-life of semaglutide.
The trial design is outlined in Figure 5-1.

Eligible subjects fulfilling all randomisation criteria at visit 2 will be randomised in a 2:1 manner to 
receive either semaglutide s.c 2.4 mg once-weekly or semaglutide placebo once-weekly as an 
adjunct to a reduced-calorie diet and increased physical activity. 
A sub-population of approximately 135 randomised subjects; corresponding to~3% of the subjects 
in the phase 3a programme will have their body composition assessed by DEXA at screening and 
end-of-treatment to demonstrate that weight loss is primarily caused by reduction in fat mass, in 
accordance with the EMA and FDA guidelines66, 67.

End of trial definition
The end of the trial is defined as the date of the last visit of the last subject in the trial. 
5.4
Scientific rationale for trial design
The treatment duration of the trial is 68 weeks with an additional 7 weeks follow-up (without 
treatment). A 68-week treatment duration (including 52 weeks on target dose) is considered 
sufficient to assess weight loss, safety and tolerability in the phase 3 weight management 
development programme in accordance with regulatory guidelines64, 65. The 7 weeks follow-up 
period is included to account for the exposure and long half-life of semaglutide. 
A randomised, double-blinded, placebo-controlled, multi-centre trial design is chosen to minimise 
bias in the assessment of the effect and safety of semaglutide s.c. 2.4 mg once-weekly versus 
semaglutide placebo, as an adjunct to a reduced calorie diet and increased physical activity.
5.5
Justification for dose
Results from the phase 2 dose-finding trial (NN9536-4153) showed that the semaglutide s.c. 0.4 mg 
once-daily dose was most effective in terms of weight loss while displaying an acceptable 
tolerability profile. Using population pharmacokinetic (PK) modelling, it was estimated that a once-
weekly maintenance dose of 2.4 mg semaglutide s.c. will result in similar Cmax at steady-state as 
that obtained by the once-daily 0.4 mg semaglutide s.c. dose in trial NN9536-4153.
A maintenance dose of 2.4 mg semaglutide s.c. once-weekly has been chosen for the phase 3 weight 
management development programme. The once-weekly dosing is anticipated to ease the burden of 
drug administration in clinical practice. Subjects will be initiated at a once-weekly dose of 0.25 mg 
and follow a fixed-dose escalation regimen, with dose increases every 4 weeks (to doses of 0.5, 1.0, 
1.7 and 2.4 mg/week), until the target dose is reached after 16 weeks.
It is well known that to mitigate GI side effects with GLP-1 RA treatment, dose escalation to the 
target dose is required. Based on experience from the semaglutide T2D development programme, a 
similar fixed-dose escalation regimen was selected, with dose escalation every 4 weeks until the 
target dose of 2.4 mg is reached after 16 weeks.
Please refer to Section 7.1 for more details on treatment doses.

recommended target dose of 2.4 mg semaglutide once-weekly or the corresponding volume of 
placebo. 
!
If a subject does not tolerate the recommended target dose of 2.4 mg once-weekly, the subject 
may stay at the lower dose level of 1.7 mg once-weekly. This should only be allowed if the 
subject would otherwise discontinue trial product completely and if considered safe to continue 
on trial product, as per the investigator’s discretion. It is recommended that the subject makes at 
least one attempt to re-escalate to the recommended target dose of 2.4 mg once-weekly, as per 
the investigator’s discretion.

Injections may be administered in the thigh, abdomen or upper arm, at any time of day 
irrespective of meals. Subjects should be encouraged to inject in the same area throughout the 
trial, but changing between left and right side is allowed.
!
If a single dose of trial product is missed, it should be administered as soon as noticed, provided 
the time to the next scheduled dose is at least 2 days (48 hours). If a dose is missed and the next 
scheduled dose is less than 2 days (48 hours) away, the subject should not administer a dose 
until the next scheduled dose. A missed dose should not affect the scheduled dosing day of the 
week.
!
If ≥ 2 consecutive doses of trial product are missed, the subject should be encouraged to re-
commence the treatment if considered safe as per the investigator’s discretion and if the subject 
does not meet any of the discontinuation criteria (Section 8.1). The trial product should be 
continued as early as the situation allows. The missed doses should not affect the scheduled 
dosing day of the week. The start dose for re-initiation of trial product is at the investigator’s 
discretion. In case of questions related to re-initiation of trial product, the investigator should 
consult Novo Nordisk global medical expert.

The investigator must document that training in the DFU has been given to the subjects orally and
in writing at the first dispensing visit. Training must be repeated,, during the trial at regular intervals 
in order to ensure correct use of the medical device. Training is the responsibility of the investigator 
or a delegate.
7.1.2
Diet and physical activity counselling
All subjects in both treatment arms will receive counselling with regards to diet (500 kcal deficit per 
day relative to the estimated total energy expenditure (TEE) calculated once at randomisation) and 
physical activity (150 min of physical activity per week is encouraged, e.g. walking or use the 
stairs). Counselling should be done by a dietician or a similar qualified healthcare professional 
every 4th week via visits/phone contacts. Subjects will be instructed to record their food intake and 
physical activity daily (via paper diary, app or similar tool) in order to assist and evaluate their 
lifestyle intervention.
After randomisation the subjects can use a tool of their own choices (paper/app/other tool) for 
recording, ensuring it can be reviewed for content and number of entries during diet and physical 
activity counselling. Subjects must receive instructions in how to capture their physical activity and 
food intake. The subjects should keep diary of physical activity and food intake on a daily basis.
Calculation of estimated TEE
The TEE is calculated by multiplying the estimated Basal Metabolic Rate (BMR) (Table 7-4) with a 
Physical Activity Level value of 1.3.70

Discontinuation/Withdrawal criteria 
The subject may be discontinued at any time during the trial at the discretion of the investigator for 
safety, behavioural, compliance or administrative reasons. 
Efforts must be made to have the subjects, who discontinue trial product, to continue in the trial. 
Subjects must be educated about the continued scientific importance of their data, even if they 
discontinue trial product. Only subjects who withdraw consent will be considered as withdrawn 
from the trial. 
8.1
Discontinuation of trial treatment
!
Discontinuation of treatment can be decided by either the investigator or the subject.
!
Subjects who discontinue trial product should continue with the scheduled visits and 
assessments to ensure continued counselling and data collection.
!
If the subject does not wish to attend the scheduled clinic visits, efforts should be made to 
have the visits converted to phone contacts. However all efforts should be made to have the 
subject attend at least the ‘end of treatment’ clinic visit containing the final data collection of 
primary and confirmatory secondary efficacy endpoints, and the ‘end of trial’ visit.
!
The ‘end of trial’ visit is scheduled approximately 7 weeks after the final data collection to 
ensure the safety of the subject.
!
If the subject refuses to attend the ‘end of treatment’ and/or ‘end of trial’ visit, information 
about the attempts to follow up with the subject must be documented in the subject’s 
medical record.
The subject must be discontinued from trial product, if any of the following applies:
1. Included in the trial in violation of the inclusion and/or exclusion criteria and/or randomisation
criteria
2. Safety concern as judged by the investigator
3. Calcitonin ≥ 100 ng/L (see Appendix 8)
4. Suspicion of pancreatitis
5. Pregnancy
6. Intention of becoming pregnant
7. Simultaneous participation in another clinical trial of an approved or non-approved 
investigational medicinal product.
If acute pancreatitis is suspected, appropriate actions should be initiated, including local 
measurement of amylase and lipase (see Appendix 4 for reporting).
Subjects meeting discontinuation of trial product criterion no. 4 are allowed to resume trial product 
if the Atlanta criteria71 are not fulfilled and thus the suspicion of acute pancreatitis is not confirmed.

Trial product may be resumed for subjects with a gallstone-induced pancreatitis in case of 
cholecystectomy.
Subjects meeting discontinuation of trial product criteria no. 2, 5 and 6 are allowed to resume trial 
product, if the criteria are no longer met (see Section 8.1.1).
A subject who does not fulfil the eligibility criteria must not be randomised. If a subject is 
randomised in violation of inclusion, exclusion or randomisation criteria, this will be handled as an 
important protocol deviation, and the IEC/IRB and regulatory authorities must be notified according 
to local requirements. 
The primary reason for discontinuation of trial product must be specified in the source data at the 
time of discontinuation, and subject should continue to follow the visit and assessment schedule. A 
change in ‘treatment status’ must be made in IWRS to discontinue trial product. If subject is not 
allowed to resume trial product, the reason for discontinuation will be recorded in the ‘end of
treatment’ form in the CRF, and final drug accountability must be performed. 
8.1.1
Temporary discontinuation of trial treatment
If a subject has discontinued trial product due to temporary safety concern not related to trial 
product and is allowed to resume, the subject should follow the guide for missed doses (Section 
7.1). Similarly, a subject who discontinues trial product on their own initiative should be 
encouraged to resume trial product (Section 7.1). 
Each missed dose should be recorded in the CRF, as per subject’s recollection. If a ‘treatment 
status’ session previously has been made in IWRS to indicate discontinuation of trial product, a new 
“treatment status” session must be made to resume trial product.
8.2
Withdrawal from the trial
A subject may withdraw consent at any time at his/her own request.
If a subject withdraws consent, the investigator must ask the subject if he/she is willing, as soon as 
possible, to have assessments performed according to the ‘end of treatment’ visit. See the flowchart 
for data to be collected. 
Final drug accountability must be performed even if the subject is not able to come to the trial site. 
The investigator must make a ‘treatment status’ session in IWRS to discontinue trial product.
If a subject withdraws from the trial, he/she may request destruction of any samples taken and not 
tested, and the investigator must document this in the medical record.
If the subject withdraws consent, Novo Nordisk may retain and continue to use any data collected 
before such a withdrawal of consent.

Although a subject is not obliged to give his/her reason(s) for withdrawing, the investigator must 
make a reasonable effort to ascertain the reason(s), while fully respecting the subject's rights. Where 
the reasons are obtained, the primary reason for withdrawal must be specified in the ‘end of trial’
form in the CRF.
8.2.1
Replacement of subjects
Subjects who discontinue trial product or withdraw from trial will not be replaced.
8.3
Lost to follow-up
A subject will be considered lost to follow-up if he or she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the trial site. 
The following actions must be taken if a subject fails to return to the trial site for a required visit:
!
The site must attempt to contact the subject and reschedule the missed visit as soon as possible 
and counsel the subject on the importance of maintaining the assigned visit schedule and 
ascertain whether or not the subject wishes to and/or should continue in the trial.
!
Before a subject is deemed lost to follow-up, the investigator must make every effort to regain 
contact with the subject (where possible, at least three telephone calls and, if necessary, a 
certified letter to the subject's last known mailing address or local equivalent methods). If 
attempts have failed, family members or other contacts consented by the subject can be 
contacted for alternative contact details. These contact attempts should be documented in the 
subject's source document.
!
Should the subject continue to be unreachable at 'end of treatment' visit, he/she will be 
considered to have withdrawn from the trial with a primary reason of 'lost to follow-up'. 
9
Trial assessments and procedures
!
Trial procedures and their timing are summarised in the flowchart. 
!
Informed consent must be obtained before any trial related activity, see Appendix 3.
!
All screening evaluations must be completed and reviewed to confirm that potential subjects 
meet all eligibility criteria. 
!
The investigator will maintain a screening log to record details of all subjects screened and to 
confirm eligibility or record reason for screen failure, as applicable.
!
At screening, subjects will be provided with a card stating that they are participating in a trial 
and giving contact details of relevant trial site staff. 
!
Adherence to the trial design requirements, including those specified in the flowchart, is 
essential and required for trial conduct. 
!
Assessments should be carried out according to the clinic’s standard of practice unless 
otherwise specified in the current section. Efforts should be made to limit the bias between 
assessments. The suggested order of the assessments:

3. Patient reported outcome questionnaires (see Section 9.1.2) and mental health assessment 
instruments (see Section 9.4.1)
4. Other assessments 
!
Source data of clinical assessments performed and recorded in the CRF must be available and 
will usually be the subject’s medical records. Additional recording to be considered source data 
includes, but is not limited to laboratory reports, ECG, diary recordings, clinical outcome 
assessments. Ensure to transcribe into the CRF :
!
Diary:
o
Compliance with diet from screening to randomisation according to the 
randomisation criteria 
o
Dosing information prior to PK sampling
o
Number of active minutes per week from physical activity diary
o
Number of days per week with at least one entry in the food diary
!
Evaluations of ECG
!
Subject must receive instructions in how to capture their daily food intake in the handed out 
food dairy from screening to randomisation. Entries must be evaluated in accordance with the 
randomisation criteria. 
!
Subjects must receive training in how to collect dosing information prior to PK sampling in a 
designated paper diary.
!
Only the subject can make entries and corrections in the diaries, unless the section is specified 
for site staff.
!
The barriers and motivation interview identifies barriers to and motivation for lifestyle change 
and compliance with the protocol. The interview will be conducted at screening to assist in 
identifying subjects who are unable or unwilling to comply with protocol procedures as per the 
exclusion criteria. In addition, the interview will ensure that any minor barriers are addressed 
during lifestyle counselling.
!
The results of the interview will not be entered into the CRF. It will be at the 
investigator’s discretion to evaluate the motivation of the subject and related eligibility.
!
Subject’s weight history must be recorded in the subject’s medical record. 
!
Review of diaries, mental health assessment instruments, ECG, and laboratory reports must be 
documented either on the documents or in the subject's medical record. If clarification of entries 
or discrepancies is needed, the subject must be questioned and a conclusion made in the 
subject's source documents. Care must be taken not to bias the subject.
!
Repeat laboratory samples may be taken for technical issues and unscheduled samples or 
assessments may be taken for safety reasons. Please refer to Appendix 2 for further details on 
laboratory samples.

For subjects receiving antihypertensive or lipid-lowering treatment, the investigator should 
evaluate changes in the subject’s treatment intensity within each therapeutic area. The 
evaluation should be based on whether an overall change from randomisation until the time of 
the evaluation has occurred (i.e., either increase, decrease or no change) after reviewing all 
available relevant information e.g., changes in drug dose, drug class, number of drugs or a 
combination of these.
!
The investigator will evaluate the subject’s glycaemic status periodically during the trial as 
detailed in the flowchart based on all available relevant information e.g. medical records, 
concomitant medication, blood glucose parameters (HbA1c, FPG) and AEs. The subject’s 
glycaemic status will be categorised as normo-glycaemia, prediabetes or diagnosed with type 2 
diabetes according to the American Diabetes Association’s definitions72.
!
For subjects in the DEXA sub-population, DEXA scan must be performed according to the 
manual from the supplier.

Efficacy assessments 
Planned time points for all efficacy assessments are provided in the flowchart.
9.1.1
Body measurements
!
Body weight should be measured at all site visits without shoes, on an empty bladder and only 
wearing light clothing. It should be measured on a digital scale and recorded in kilograms or 
pounds (one decimal) using the same scale throughout the trial. 
!
The scale must be calibrated yearly as a minimum.
!
Height is measured without shoes in centimetres or inches (one decimal). BMI will be 
calculated by the CRF from screening data and must be in agreement with inclusion criterion 
no. 3.
!
Waist circumference is defined as the abdominal circumference located midway between the 
lower rib margin and the iliac crest. 
!
Measures must be obtained in standing position with a non-stretchable measuring tape and to 
the nearest cm or inch. 
!
The tape should touch the skin but not compress soft tissue and twists in the tape should be 
avoided. The subject should be asked to breathe normally. The same measuring tape should be 
used throughout the trial. The measuring tape will be provided by Novo Nordisk to ensure 
standardisation.
9.1.2
Clinical outcome assessments
Subjects should be given the opportunity to complete the questionnaires by themselves without 
interruption. Each of the questionnaires takes approximately 10 minutes to complete.
The following patient reported outcome questionnaires will be used:

The definitions of AEs and SAEs can be found in Appendix 4.
The investigator is responsible for detecting, documenting, recording and following up on events 
that meet the definition of an AE or SAE.
9.2.1
Time period and frequency for collecting AE and SAE information
All AEs will be collected from the first trial-related activity after obtaining informed consent and 
until ‘end of trial’ visit, at the time points specified in the flowchart. 
All SAEs will be recorded and reported to Novo Nordisk or designee within 24 hours, as indicated 
in Appendix 4. The investigator must submit any updated SAE data to Novo Nordisk within 24 
hours of it being available.

Investigators are not obligated to actively seek for AE or SAE in former trial subjects. However, if 
the investigator learns of any SAE, including a death, at any time after a subject has been 
discontinued from/completed the trial, and the investigator considers the event to be 
possibly/probably related to the investigational trial product or trial participation, the investigator 
must promptly notify Novo Nordisk.
The method of recording, evaluating and assessing causality of AE and SAE and the procedures for 
completing and transmitting SAE reports are provided in Appendix 4.
Timelines for reporting of AEs including events for adjudication, Section 9.2.1.1, are listed in
Figure 9-1.
Some AEs require additional data collection via a specific event form. This includes medication 
errors observed during the trial. The relevant specific events are listed in Table 9-1 and the 
reporting timelines in Figure 9-1.

Events for adjudication
Event adjudication will be performed for adverse events in randomised subjects.
These events are reviewed by an independent external event adjudication committee in a blinded 
manner, refer to Appendix 3 for further details.
There are 4 ways to identify events relevant for adjudication as described below:
!
Investigator-reported events for adjudication: When reporting AEs, the investigator must select 
the appropriate AE category based on pre-defined criteria (see Table 9-1 and Appendix 4)
!
Death
!
AE Search (standardised screening): All AEs not directly reported by the investigator as 
requiring adjudication, will undergo screening to identify potential events for adjudication. The 
investigator can be queried to provide additional information related to the reported AE, e.g. 
alternative aetiology, underlying cause(s) and/or clinical details.
!
EAC-identified events: When reviewing source documents provided for another event for 
adjudication, the EAC can identify additional events in scope for adjudication that were not 
initially reported by the investigator. In these instances, the investigator will be notified of the 
newly identified event and has the option to report the EAC-identified event. Regardless of 
whether the investigator decides to report the event, it will undergo adjudication. Occasionally, 
EAC-identified events may require the investigator to collect additional source documents, 
which should be provided by uploading to the event adjudication system (EAS).
With the exception of EAC-identified events, an event-specific adjudication form for the event in 
question should be completed in the CRF within 14 calendar days of the investigator's first 
knowledge of the event.

Copies of collected source documents should be labelled with trial ID, subject and AE number, 
redacted (anonymised of personal identifiers) and uploaded to the EAS within 4 weeks according to 
instructions outlined in the event adjudication site manual. If no, or insufficient source documents 
are provided to the adjudication supplier, the investigator can be asked to complete a clinical 
narrative to be uploaded to the EAS. 
If new information becomes available for an event sent for adjudication, it is the responsibility of 
the investigator to ensure the new information is uploaded to the EAS.
9.2.2
Method of detecting AEs and SAEs
Care should be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and 
non-leading verbal questioning of the subject is the preferred method to inquire about events.
9.2.3
Follow-up on AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each subject at 
subsequent visits/contacts. All SAEs will be followed until resolution, stabilization, or if the event 
is otherwise explained (e.g. chronic condition) or the subject is lost to follow-up (as defined in 
Section 8.3). Further information on follow-up procedures is given in Appendix 4.
9.2.4
Regulatory reporting requirements for SAEs
Prompt notification by the investigator to Novo Nordisk of a SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of subjects and the safety of a trial 
product under clinical investigation are met. 
Novo Nordisk has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a trial product under clinical investigation. Novo Nordisk 
will comply with country-specific regulatory requirements relating to safety reporting to the 
regulatory authority, IRB/IEC, and investigators.
Investigator safety reports must be prepared for SUSARs according to local regulatory requirements 
and Novo Nordisk policy and forwarded to investigators as necessary.
An investigator who receives an investigator safety report describing a SAE or other specific safety 
information (e.g. summary or listing of SAEs)from Novo Nordisk, will review and then file it along 
with the IB and will notify the IRB/IEC, if appropriate according to local requirements.

Treatment of overdose
Overdoses of up to 4 mg in a single dose, and up to 4 mg in a week have been reported in clinical 
trials. The most commonly reported AE was nausea. All subjects recovered without complications. 
There is no specific antidote for overdose with semaglutide. In the event of an overdose, appropriate 
supportive treatment should be initiated according to subject’s clinical signs and symptoms.
The overdose must be reported as a medication error (Appendix 4) and for reporting timeline see 
Section 9.2.1.
In the event of an overdose, the investigator should closely monitor the subject for overdose-related 
AE/SAE and laboratory abnormalities. A prolonged period of observation and treatment may be 
necessary, taking into account the long half-life of semaglutide of approximately one week. 
Decisions regarding dose interruptions or modifications will be made by the investigator based on 
the clinical evaluation of the subject.

A concomitant illness is any illness that is present at the start of the trial (i.e. at the first visit) or 
found as a result of a screening procedure or other trial procedures performed before exposure to 
trial product. 
Medical history is a medical event that the subject has experienced in the past. Only relevant and 
significant medical history as judged by the investigator should be recorded. Findings of specific 
medical history should de described in designated forms.
As part of the medical history, information related to history of gallbladder disease, breast 
neoplasm, colon neoplasm, skin cancer, and psychiatric disorder will be recorded. Follow-up 
questions will be asked at the end of trial related to breast neoplasm and colon neoplasm
In case of an abnormal and clinically significant finding, the investigator must record the finding on 
the Medical History/Concomitant Illness form if it is present at screening. Any new finding 
fulfilling the AE definition (see Appendix 4) during the trial and any clinically significant 
worsening from baseline must be reported as an AE (see Section 9.2).
9.4.1
Mental health assessment instruments
!
PHQ-977 is a 9-item depression module of the patient health questionnaire, which is a self -
administered diagnostic tool used for assessment of mental disorders. The questionnaire will be 
available in a linguistically validated translated version. 
!
C-SSRS78 is a detailed questionnaire assessing both suicidal behaviour and suicidal ideation. 
The questionnaire will be administered as an interview by the investigator or a qualified 
delegate. The questionnaire (C-SSRS Baseline and C-SSRS Since Last Visit) will be available 
in a linguistically validated translated version.
!
Prior to administering the C-SSRS questionnaire, the investigator or qualified delegate 
must complete sufficient training.
If a subject has a PHQ-9 score of 10-14 (both inclusive) the subject should be referred to a mental 
health professional (MHP) if judged relevant by the investigator. If referral is not deemed relevant 
this along with the reason why must be documented in the subject’s medical records.
A subject must be referred to a MHP if:
!
the subject has a PHQ-9 score ≥15 or
!
the subject has any suicidal behaviour or
!
the subject has any suicidal ideation of type 4 or type 5 on any C-SSRS assessment or
!
in the opinion of the investigator, it is necessary for the safety of the subject
If one or more of the referral criteria are met, the investigator should explain to the subject why the 
referral and psychiatric evaluation by a MHP is needed. If the subject refuses to be referred to a 
MHP, the subject’s decision should be documented in subject’s medical record and the investigator

must assess if it is safe for the subject to continue in the trial or if the subject should be discontinued 
from trial product.
If a subject’s psychiatric disorder can be adequately treated with psychotherapy and/or 
pharmacotherapeutic treatment, then the subject, at the discretion of the investigator (and in 
agreement with the MHP), may continue in the trial. Otherwise, the subject must be discontinued 
from trial product due to safety concern as judged by the investigator.
9.4.2
Physical examinations
!
A physical examination will include assessments of the general appearance, thyroid gland, 
breast (females), and abdomen, as well as the cardiovascular and respiratory systems.
!
Investigators should pay special attention to clinical signs related to previous serious illnesses.
9.4.3
Vital signs
!
The method for measuring systolic and diastolic blood pressure needs to follow the standard 
clinical practice at site.
!
Blood pressure (diastolic and systolic) and pulse measurements should be preceded by at least 5 
minutes of rest for the subject in a quiet setting without distractions (e.g. television, cell 
phones).
!
Blood pressure and pulse measurements will be assessed in a sitting position with a completely 
automated device. Manual techniques will be used only if an automated device is not available.
9.4.4
Electrocardiograms
!
12-lead ECG will be obtained as outlined in the flowchart using an ECG machine that 
automatically calculates the heart rate and measures PR, QRS, QT, and QTc intervals.
!
In a sub-population, ECGs will be collected for central storage at randomisation and ‘end of 
treatment’ visit for potential future assessment.
9.4.5
Clinical safety laboratory assessments
All protocol-required laboratory assessments, as defined in Appendix 2, must be conducted in 
accordance with the flowchart and the laboratory manual.

Immunogenicity assessments
Blood samples for determination of serum antibodies against semaglutide, including cross reactivity 
to endogenous GLP-1 will be taken during the trial at visits specified in the flowchart. Samples 
taken at the ‘end of trial’ visit which are positive for anti-semaglutide antibodies will be further 
characterised for in vitro neutralising effect towards semaglutide. In addition, if samples taken at the 
‘end of trial’ visit are also positive for cross-reactivity against endogenous GLP-1, the samples will 
be analysed for in vitro neutralising effect towards endogenous GLP-1.The results of the analysis 
will only be disclosed after completion of the clinical trial report (CTR) if required by local 
regulation.

Pharmacokinetics
!
Single blood samples for measuring plasma concentration of semaglutide will be drawn for both 
semaglutide and semaglutide placebo subjects on visits specified in the flowchart.
!
Subject must be instructed to withhold their trial product dose in the morning of the clinic visit
until blood sampling has been performed.
!
The PK dosing information should be transcribed into the CRF for the last 2 doses of trial 
product, including time, date and injection site.
!
The exact timing of obtaining the PK sample must be recorded on the laboratory form.
!
The dual purpose of measuring plasma semaglutide levels is to perform population PK (Pop-
PK) analyses and to assess the level of drug interference in the anti-semaglutide antibody 
analysis. 
Samples will be used to evaluate the pharmacokinetics of semaglutide. Each plasma sample will be 
divided into 2 aliquots (e.g. one for pharmacokinetics and a backup,) and may also be used to 
evaluate safety or efficacy aspects that address concerns arising during or after the trial. Residual 
sample material may be used for exploratory investigation of metabolites a nd bioanalysis assay 
development and troubleshooting in relation to the pharmacokinetic assay.

Severe hypersensitivity
In the event of a severe immediate hypersensitivity reaction to trial product, blood sampling for 
assessment of anti-semaglutide IgE and binding antibodies should be conducted after 1–2 weeks 
and 7 weeks of trial product wash-out (i.e. after the subject had the last dose of the trial product). 
In these cases, it is also recommended to test for tryptase (total and/or mature tryptase) within 3 
hours of the hypersensitivity reaction. In case a tryptase sample was collected within 3 hours of the 
event of hypersensitivity reaction, a baseline tryptase sample should be taken at the same time as 
the IgE sample is obtained (after 1-2 weeks of trial product wash-out). Tryptase concentrations (if 
measured) as well as results of anti-semaglutide antibody and IgE isotype anti-semaglutide 
antibodies will be collected by Novo Nordisk and the results will be reported in the CTR.
10 Statistical considerations 
Taxonomy of week 68 assessments
For each subject a given assessment at week 68 may be available or missing and Table 10-1
describes the taxonomy for this. Note, this is done per assessment and per subject; subjects may be 
a different type for different assessments (a subject may have “available on randomised treatment 
(AT)” for body weight but “missing on randomised treatment (MT)” for waist circumference).

10.1
Sample size determination 
The sample size and thereby the power for this trial is primarily defined to support safety. However,
no formal statistical inference is planned based on number of adverse events. Given the trial sample 
size, the power of statistical tests for effect endpoints is described below.
The tests of superiority of semaglutide 2.4 mg to semaglutide placebo for the primary and 
confirmatory secondary endpoints are performed using the fixed-sequence statistical strategy. This 
strategy tests the endpoints using a predefined hierarchical order, all at the significance level of 5%, 
moving to test the next endpoint only after a statistically significant superiority result (p-value < 
5%) on the previous endpoint. The test hierarchy is given in Table 10-2 with underlying 
assumptions, marginal power and effective power. The effective power is calculated under the 
assumption of independence of endpoints by multiplying the respective marginal powers 
successively. As the two primary endpoints are included in the statistical testing hierarchy, 
significant superiority of semaglutide 2.4 mg vs. semaglutide placebo must be demonstrated for 
each of the primary endpoints.
In the analysis approach addressing the primary estimand, week 68 assessments from retrieved 
subjects (AD) are used. These data are also used to impute missing measurements at week 68 for 
non-retrieved subjects (MD). The imputation is done separately within each treatment arm (see 
description below). However, for the power calculations missing values (MT and MD), regardless 
of treatment arm, are assumed to be similar to semaglutide placebo subjects. These assumptions are 
likely conservative with respect to the power, and correspond to the jump to reference sensitivity 
analysis planned below.
Assumptions
The common assumptions for the power calculations are:

20% of subjects discontinue permanently and

60% of these are retrieved (AD) at week 68 
!
All subjects in the semaglutide placebo arm are assumed to have same effect as subjects who 
complete the trial on semaglutide placebo (AT)
!
Retrieved subjects (AD) in the semaglutide 2.4 mg arm are assumed to have an effect 
corresponding to half the treatment difference (compared to semaglutide placebo) of subjects 
who complete the trial on semaglutide 2.4 mg (AT)
!
Non-retrieved subjects (MD) in the semaglutide 2.4 mg arm are assumed to have an effect 
corresponding to semaglutide placebo
Further assumptions made to calculate the power for each of the primary and confirmatory 
secondary endpoints are based on findings from other projects conducted by Novo Nordisk 
(NN8022 (SCALE), NN9535 (SUSTAIN), NN9924 (PIONEER)), and trial NN9536-4153 and are 
presented in Table 10-2.
Given these assumptions, the sample size of 1950 subjects (1300 in the semaglutide 2.4 mg once-
weekly and 650 in the semaglutide placebo arm), gives an effective power (marginal powers 
multiplied) of 99% for the first seven endpoints in the hierarchical testing procedure. As sample size 
is primarily driven by safety, additional scenarios for assumptions are not included due to the 
overall high power.

Definition of analysis sets
Two analysis sets are defined:
!
The full analysis set (FAS) includes all randomised subjects according to the intention-to-treat 
principle.
!
The safety analysis set (SAS) includes all randomised subjects exposed to at least one dose of 
randomised treatment. 
Any observation excluded from the analysis will be documented before database lock with the 
reason for exclusion provided.
Two observation periods are defined for each subject
!
In-trial: The in-trial period is defined as the uninterrupted time interval from date of 
randomisation to date of last contact with trial site.
!
On-treatment (with trial product): A time-point is considered as ‘on-treatment’ if any dose of 
trial product has been administered within the prior 2 weeks (14 days). The on-treatment period
is defined as all times which are considered on-treatment.
!
In general, the on-treatment period will therefore be from the date of first trial product 
administration to date of last trial product administration excluding potential off-treatment 
time intervals triggered by at least two consecutive missed doses.

For the evaluation of adverse events the lag time for each on-treatment time interval is 7 
weeks (49 days).
The in-trial and on-treatment periods define the patient years of observation (PYO) and patient 
years of exposure (PYE), respectively, as the total time duration in the periods.
10.3
Statistical analyses
If necessary, a statistical analysis plan (SAP) may be written in addition to the protocol, including a 
more technical and detailed elaboration of the statistical analyses. The SAP will be finalised before 
database lock.
Effect endpoints will be analysed using the FAS; safety endpoints will be analysed using the SAS. 
Results from statistical analyses will generally be accompanied by two-sided 95% confidence 
intervals and corresponding p-values. Superiority will be claimed if p-values are less than 5% and 
the estimated treatment contrasts favours semaglutide 2.4 mg. 
Handling of missing baseline data
The last available and eligible observation at or before randomisation is used as the baseline value. 
If no assessments are available, the mean value at randomisation across all subjects is used as the 
baseline value.
10.3.1
Primary endpoint
Definition of primary endpoint: % weight change
Change from baseline (week 0) to week 68 in body weight (%) is defined as
% weight change = (body weight at week 68 – body weight at baseline)
body weight at baseline
×100.
Definition of primary endpoint: 5% responders
A body weight reduction of at least 5% from baseline (week 0) to week 68 is defined as 
5% responder = 1 if  % weight change ≤ – 5%
0 if  % weight change > – 5%
Analyses addressing the primary estimand
The following statistical analyses and imputation methods are designed to address the primary 
estimand, i.e. to assess the effectiveness of semaglutide 2.4 mg.

The analysis model for % weight change is a linear regression (ANCOVA) of % weight change 
with randomised treatment as a factor and baseline body weight (kg) as covariate. The estimated 
treatment difference between semaglutide 2.4 mg and semaglutide placebo will be reported together 
with the associated two-sided 95% confidence interval (CI) and corresponding p-value.
The analysis model for the 5% responder endpoint is a logistic regression using randomised 
treatment as a factor and baseline body weight (kg) as covariate. The estimated odds ratio (OR) 
between semaglutide 2.4 mg and semaglutide placebo will be reported together with the associated 
two-sided 95% CI and corresponding p-value.
The superiority tests of semaglutide 2.4 mg vs. semaglutide placebo will be carried out as follows 
for the two analysis models.
Let μsemaglutide and μsemaglutide placebo denote the true mean of % weight change for semaglutide 2.4 mg 
and semaglutide placebo group, respectively. The null and alternative hypotheses tested are

$:  <   !.
The hypothesis will be rejected and superiority claimed, if the upper limit of the estimated two-
sided 95% CI is below 0.
Let ORsemaglutide/semaglutide placebo denote the true odds ratio between semaglutide 2.4 mg and 
semaglutide placebo. The null and alternative hypotheses tested are
: &'/  ! ≤1 "#
$: &'/  ! > 1.
The hypothesis will be rejected and superiority claimed, if the lower limit of the estimated two-
sided 95% CI is above 1.
Handling of missing week 68 values for the primary estimand
All available data at week 68 (AT and AD) are used and missing values (MT and MD) at week 68 
will be imputed and the endpoints will be derived from the imputed values. Several approaches for 
imputation will be applied. First, a description of the primary imputation approach to address the 
primary estimand for the primary endpoints is given followed by a description of the sensitivity 
analyses used to assess the robustness of the primary analysis results. The sensitivity analyses 
investigate how assumptions on body weight development after discontinuation of randomised 
treatment impact the estimated treatment contrasts between semaglutide 2.4 mg and semaglutide 
placebo. An illustration of all imputation approaches for the effectiveness estimand is given in 
Figure 10-1.

Multiple imputation approach using retrieved subjects (RD-MI): The primary imputation approach 
for the primary estimand is a multiple imputation similar to the one described by McEvoy 79. 
Missing body weight measurement at week 68 for non-retrieved subjects (MD) are imputed using 
assessments from retrieved subjects (AD) in each randomised treatment arm. This will be done 
according to the timing of last available observation (LAO) of body weight. Missing body weight 
measurements at week 68 for subjects on randomised treatment (MT) are imputed by sampling from 
available measurements at week 68 from subjects on randomised treatment (AT) in the relevant 
randomised treatment arm. The multiple imputation approach is done in three steps:
1. Imputation: Defines an imputation model using retrieved subjects (AD) from FAS and done 
within groups defined by randomised treatment and the timing of the LAO of body weight. 
The model will be a linear regression of body weight (kg) at week 68 with gender 
(male/female), baseline BMI (kg/m2) (in categories 27-<35, 35-<40, ≥40) as factors and 
baseline body weight (kg) and LAO of body weight (kg) as covariates. No interactions will be 
included. The grouping of timing will be done by quarters (intervals of 17 weeks). If timing 
by quarters is too restrictive, halves (intervals of 34 weeks) or excluding timing will be used. 
If any subjects are MT, an imputation model for missing body weight measurements at week 
68 for MT subjects will also be defined using AT subjects in a similar way. The estimated 
posterior distribution for the parameters (regression coefficients and variances) in the 
imputation models are then used to impute missing week 68 body weight values for each 
randomised treatment arm. This will be done 1,000 times and results in 1,000 complete data 
sets.
2. Analysis: Analysis of each of the 1,000 complete data sets, using the analysis models 
(ANCOVA and logistic regression) results in 1,000 times 2 estimations.
3. Pooling: Integrates the 1,000 times 2 estimation results into two final results using Rubin’s 
formula.
Based on NN9536-4153 phase 2 results 1,000 copies should be sufficient to establish stable results.
If 1,000 copies are insufficient, 10,000 copies will be used. The multiple imputations will be 
generated using Novo Nordisk trial number 95364373 as seed number.
Sensitivity analyses
Jump to reference multiple imputation approach (J2R-MI): Missing values of body weight at week 
68 (MT and MD) for both the semaglutide 2.4 mg and semaglutide placebo group are imputed by 
sampling among all available assessments at week 68 in the semaglutide placebo group (AT and 
AD). This approach makes the assumption that subjects instantly after discontinuation lose any 
effect of randomised treatment beyond what can be expected from semaglutide placebo treatment as 
adjunct to reduced-calorie diet and increased physical activity80. The multiple imputation approach 
is done as above with the first step replaced by

1. Imputation: Defines an imputation model using semaglutide placebo subjects from FAS with 
a week 68 measurement (AT and AD). The model will be a linear regression of body weight 
(kg) at week 68 with gender (male/female), BMI (kg/m2) (in categories 27-<35, 35-<40, ≥40
as factors and baseline body weight (kg) as covariate. No interactions will be included. The 
estimated posterior distribution for the parameters (regression coefficients and variances) in 
the imputation models are then used to impute missing week 68 body weight values for each 
randomised treatment arm. This will be done 1,000 times and results in 1,000 complete data 
sets.
The jump to reference approach is the basis for the sample size calculations. 
A single imputation approach as done by Sacks81 (S1-SI and S2-SI): Missing weight measurements
at week 68 for non-retrieved subjects (MD) are imputed using a weight regain rate of 0.3 kg/month 
after LAO but truncated at no change from baseline whenever the extrapolation would lead to a 
positive weight gain relative to baseline. If a subject's weight at drug discontinuation represented a 
gain in weight relative to baseline, no additional gain will be imputed, and the unfavourable gain is 
carried forward to week 68. The weight regain imputation will be done for both randomised arms
(S1-SI). Additionally, a version where only the semaglutide 2.4 mg arm uses the regain rate while 
the semaglutide placebo arm uses last available observation (corresponding to a weight regain rate 
of 0 kg/month) will be performed (S2-SI). For both versions, missing weight measurements at week 
68 for subjects on randomised treatment (MT) are imputed by using LAO.
Tipping-point multiple imputation analysis (TP-MI): First, missing data are imputed according to 
the primary multiple imputation approach. Second, for the semaglutide 2.4 mg treatment arm a 
penalty will be added to the imputed values at week 68. The approach is to gradually increase this 
penalty until all confirmed conclusions from the primary analysis are reversed. For each hypothesis 
tested the specific value of the penalty that reverses the conclusion will be used to evaluate the 
robustness of the primary analysis results. This sensitivity analysis evaluates the robustness of the 
superiority conclusions.
Mixed model for repeated measurements (MMRM): This ‘MMRM for effectiveness’ will use all 
assessments regardless of adherence to randomised treatment, including assessments at week 68 for 
retrieved drop-outs (AD). The MMRM for effectiveness will be fitted using the same factor and 
covariate as for the primary analyses all nested within visit. An unstructured covariance matrix for 
measurements within the same subject will be employed, assuming that measurements for different 
subjects are independent.
Non-retrieved subjects as non-responders: For the 5% responder analysis an analysis using non-
retrieved subjects as non-responders in the logistic regressions will be done.

Analysis addressing the secondary estimand
The secondary estimand for % weight change addresses the efficacy of semaglutide 2.4 mg and will 
be assessed using a ‘MMRM for efficacy’. Week 68 assessments for retrieved drop-outs (AD) are 
not used in this analysis. The MMRM for efficacy will use assessments only from subjects who are 
taking the randomised treatment until end of treatment or until first discontinuing of randomised 
treatment. The derived date of the second consecutive missed dose will be used as the latest date for 
using assessments in this MMRM. The assessment closest in time and before the derived date of the 
second consecutive missed dose will be used as last assessment on randomised treatment. For 
subjects who initiate rescue interventions before completion or first discontinuing of randomised 
treatment, the date of starting weight management drugs or undergoing bariatric surgery will be 
used as latest date for using assessments in this MMRM. Similarly, the assessment closest in time 
and before the date of starting weight management drugs or undergoing bariatric surgery will be 
used as last assessment on randomised treatment. The MMRM for efficacy will be fitted using % 
weight change and the same factor and covariate as for the primary analyses all nested within visit. 
An unstructured covariance matrix for measurements within the same subject will be employed, 
assuming that measurements for different subjects are independent. 
The secondary estimand for 5% responders will be assessed using the same MMRM for efficacy. 
From the MMRM individually predicted values for % weight change at week 68 will be used to 
classify each subject as 5% responder or not. This classification will then be analysed using a 
logistic regression model with treatment as the only factor.
An overview of all analysis and imputation methods to address the effectiveness and efficacy 
estimands for the primary endpoints is given in Table 10-3.

Secondary endpoints
10.3.2.1
Confirmatory secondary endpoints
Confirmatory secondary endpoints are listed in Section 4 and are all included in the fixed-sequence 
statistical strategy, see above. All tests are tests of superiority of semaglutide 2.4 mg to semaglutide 
placebo. 
Analyses addressing the primary estimand
All confirmatory secondary endpoints will be analysed using the same imputation approach as used 
for the primary endpoints and to address the primary estimand. The imputation model is the same as 
for the primary endpoints with body weight replaced by assessments of the endpoint to be analysed. 
The statistical model for continuous endpoints will be ANCOVA with factor and covariate as for 
the primary endpoint % weight change with baseline body weight replaced by the baseline

assessment of the endpoint to be analysed. The statistical model for body weight responder 
endpoints will be logistic regression with factor and covariate as for the primary endpoint 5% 
responders. 
Analyses addressing the secondary estimand
The confirmatory secondary endpoints which relate to the primary objective will be analysed to 
address the secondary estimand using the same MMRM for efficacy described for the primary 
endpoints.
Sensitivity analyses for confirmatory secondary endpoints
For all continuous confirmatory secondary endpoints a sensitivity analysis using jump to reference 
as imputation approach will be carried out. For all binary confirmatory secondary endpoints a 
sensitivity analysis using non-retrieved subjects as non-responders will be carried out.
An overview of all analysis and imputation methods to address the effectiveness and efficacy 
estimands for confirmatory secondary endpoints is given in Table 10-3.
10.3.2.2
Supportive secondary endpoints
Supportive secondary endpoints are listed in Section 4. All tests are tests of superiority of 
semaglutide 2.4 mg to semaglutide placebo. 
Analyses addressing the primary estimand
The effect-related supportive secondary endpoints will be analysed using the same imputation 
approach as used for the primary endpoints and to address the primary estimand. The imputation 
model is the same as for the primary endpoints with body we ight replaced by assessments of the 
endpoint to be analysed. The statistical model for continuous endpoints will be ANCOVA with 
factor and covariate as for the primary endpoint % weight change with baseline body weight 
replaced by the baseline assessment of the endpoint to be analysed.
The statistical model for responder endpoints relating to COAs will be logistic regression with 
randomised treatment as a factor and the baseline assessment of the endpoint to be analysed as 
covariate.
For body composition endpoints assessed by DEXA, missing data at week 68 will be imputed using 
jump to reference due to the low number of expected retrieved subjects in this subset. The analysis 
method will be ANCOVA with randomised treatment as a factor and the baseline assessment of the 
endpoint to be analysed as covariate. For all DEXA derived endpoints two-sided p-values for test of 
no difference between the two treatment groups will be presented.

For lipids and biomarkers a multiplicative model will be used, i.e. the ratio between post 
randomisation measurements and baseline will be calculated instead of differences, and both the 
dependent variable and covariate will be log-transformed.
Analyses addressing the secondary estimand
The supportive secondary endpoints which relate to the primary objective will be analysed to 
address the secondary estimand using the same MMRM for efficacy described for the primary 
endpoints.
Sensitivity analyses for supportive secondary endpoints
For supportive secondary endpoints no sensitivity analysis will be carried out.
Analysis of safety endpoints
The safety endpoint pulse will be analysed using an MMRM for efficacy as described in Section
10.3.1. For amylase, lipase and calcitonin descriptive statistics will be provided. The analysis of 
calcitonin will be stratified by gender.
Adverse events will be defined as “treatment-emergent” (TEAE), if the onset of the event occurs in 
the on-treatment period (see definition in Section 10.2). TEAEs and SAEs will be summarised by 
descriptive statistics, such as frequencies and rates. No formal statistical inference will be carried 
out based on the number of TEAEs and SAEs.
An overview of all analysis and imputation methods to address the effectiveness and efficacy 
estimands for supportive secondary endpoints is given in Table 10-4.

10.4
Pharmacokinetic and/or pharmacodynamic modelling
Population PK and exposure-response analyses will be used as supportive evidence for the 
evaluation of efficacy and safety and further to support the recommended dose of semaglutide in 
subjects with obesity. First, plasma semaglutide concentrations will be analysed using a population 
pharmacokinetic model, quantifying covariate (such as baseline body weight, age, gender, race, 
ethnicity, and injection site) effects on semaglutide exposure. Second, model based estimates of 
steady-state average concentrations will be derived for each subject, in order to facilitate subsequent 
exposure-response analyses. Relevant efficacy and safety endpoints will be related to steady-state 
average concentrations and subjected to model based analysis. 
The analyses will be conducted separately for each trial and be combined into a meta-analysis, 
including the phase 2 trial and phase 3a trials with PK sampling. A modelling analysis plan will be 
prepared before first database lock in the semaglutide phase 3a programme for weight management, 
outlining details of the analyses. The modelling will be performed by Quantitative Clinical 
Pharmacology at Novo Nordisk and will be reported separately from the clinical trial reports.

Clinical laboratory tests
Appendix 2
!
The tests detailed in Table 11-1 and Table 11-2 will be performed by the central laboratory.
!
Laboratory samples specified in the protocol should be sent to the central laboratory for 
analysis.
!
Additional tests may be performed at local laboratory at any time during the trial as determined 
necessary by the investigator or required by local regulations. 
!
The laboratory equipment may provide analyses not requested in the protocol but produced 
automatically in connection with the requested analyses according to specifications in the 
laboratory standard operating procedures. Such data will not be transferred to the trial database, 
but abnormal values will be reported to the investigator. 
!
The investigator must review all laboratory results for concomitant illnesses and AEs.
!
Laboratory samples will be destroyed no later than at finalisation of the clinical trial report 
except, antibody samples which will be stored until marketing authorisation or destroyed at the 
latest 15 years from end of trial. 
!
For haematology samples (differential count) where the test result is not normal, then a part of 
the sample may be kept for up to 2 years or according to local regulations.

Subjects will be required to sign and date a statement of informed consent that meets the 
requirements of local regulations, ICH guidelines83, Declaration of Helsinki82 and the IRB/IEC 
or trial site.
!
The medical record must include a statement that written informed consent was obtained before 
any trial related activity and the date when the written consent was obtained. The authorised 
person obtaining the informed consent must also sign and date the informed consent form before 
any trial related activity.
!
The responsibility of seeking informed consent must remain with the investigator, but the 
investigator may delegate the task of informing to a medically qualified person, in accordance 
with local requirements.
!
Subjects must be re-consented to the most current version of the informed consent form(s) 
during their participation in the trial
!
A copy of the informed consent form(s) must be provided to the subject.
4) Information to subjects during trial
The site will be offered a communication package for the subject during the conduct of the trial. 
The package content is issued by Novo Nordisk. The communication package will contain written 
information intended for distribution to the subjects. The written information will be translated and 
adjusted to local requirements and distributed to the subject at the discretion of the investigator. 
All written information to subjects must be sent to IRB/IEC for approval/favourable opinion and to 
regulatory authorities for approval or notification according to local regulations.
Different initiatives for subject retention will be implemented throughout this trial. Site retention 
activities may include cooking classes, group meetings, fitness memberships and others. Materials 
and items will be supplied if locally acceptable. The retention items will be relevant for the 
subjects’ participation in the trial and/or their obesity and will not exceed local fair market value.
The initiatives for subject retention must be sent to IRB/IEC for approval/favourable opinion and to 
regulatory authorities for approval or notification according to local regulations.
5) Data protection
!
Subjects will be assigned a 6-digit unique identifier, a subject number. Any subject records or 
datasets that are transferred to Novo Nordisk will contain the identifier only; subject names or 
any information which would make the subject identifiable will not be transferred.
!
The subject and any biological material obtained from the subject will be identified by subject 
number, visit number and trial ID. Appropriate measures such as encryption or leaving out

certain identifiers will be enforced to protect the identity of subjects as required by local, 
regional and national requirements. 
!
The subject must be informed that his/her personal trial related data will be used by Novo 
Nordisk in accordance with local data protection law. The disclosure of the data must also be 
explained to the subject. 
!
The subject must be informed that his/her medical records may be examined by auditors or 
other authorised personnel appointed by Novo Nordisk, by appropriate IRB/IEC members, and 
by inspectors from regulatory authorities.
6) Committee structure
Novo Nordisk safety committee
Novo Nordisk will constitute an internal Semaglutide s.c. safety committee to perform ongoing 
safety surveillance. The Semaglutide s.c. safety committee may recommend unblinding of any data 
for further analysis, and in this case an independent ad hoc group will be established in order to 
maintain the blinding of the trial personnel.
Event adjudication committee
An independent external EAC is established to perform ongoing blinded adjudication of selected 
types of events and deaths (see Table 9-1 and Appendix 4). The EAC will evaluate events sent for 
adjudication using pre-defined definitions and guidelines in accordance with the EAC Charter. The 
evaluation is based on review of pre-defined clinical data collected by the trial sites. 
The EAC is composed of permanent members covering all required medical specialities. EAC 
members must disclose any potential conflicts of interest and must be independent of Novo 
Nordisk. The EAC will have no authorisations to impact on trial conduct, trial protocol or 
amendments.
The assessment made by both the EAC and the investigator will be presented in the clinical trial 
report. 
In this trial, cardiovascular events will be adjudicated in order to adequately characterize the 
cardiovascular safety profile, since cardiovascular disease is an important and serious comorbidity 
of obesity84. In addition, events of acute pancreatitis will be adjudicated because Novo Nordisk 
monitors these events closely, as treatment with GLP-1 RAs has been associated with acute 
pancreatitis. 
7) Publication policy
The information obtained during the conduct of this trial is considered confidential, and may be 
used by or on behalf of Novo Nordisk for regulatory purposes as well as for the general 
development of the trial product. All information supplied by Novo Nordisk in connection with this 
trial shall remain the sole property of Novo Nordisk and is to be considered confidential 
information.

No confidential information shall be disclosed to others without prior written consent from Novo 
Nordisk. Such information shall not be used except in the performance of this trial.
The information obtained during this trial may be made available to other investigators who are 
conducting other clinical trials with the trial product, if deemed necessary by Novo Nordisk. 
Provided that certain conditions are fulfilled, Novo Nordisk may grant access to information 
obtained during this trial to researchers who require access for research projects studying the same 
disease and/or trial product studied in this trial.
Novo Nordisk may publish on its clinical trials website a redacted clinical trial report for this trial.
One (or two) investigator(s) will be appointed by Novo Nordisk to review and sign the clinical trial 
report (signatory investigator) on behalf of all participating investigators. The signatory 
investigator(s) will be appointed based upon the criteria defined by the International Committee of 
Medical Journal Editors for research publications.85
Communication of results
Novo Nordisk commits to communicate and disclose results of trials regardless of outcome. 
Disclosure includes publication of a manuscript in a peer-reviewed scientific journal, abstract 
submission with a poster or oral presentation at a scientific meeting or disclosure by other means. 
The results of this trial will be subject to public disclosure on external web sites according to 
international and national regulations. Novo Nordisk reserves the right to defer the release of data 
until specified milestones are reached, for example when the clinical trial report is available. This 
includes the right not to release the results of interim analyses, because the release of such 
information may influence the results of the entire trial.
At the end of the trial, one or more scientific publications may be prepared collaboratively by the 
investigator(s) and Novo Nordisk. Novo Nordisk reserves the right to postpone publication and/or 
communication for up to 60 days to protect intellectual property.
In all cases the trial results will be reported in an objective, accurate, balanced and complete 
manner, with a discussion of the strengths and limitations. In the event of any disagreement on the 
content of any publication, both the investigators’ and Novo Nordisk opinions will be fairly and 
sufficiently represented in the publication.
Authorship
Novo Nordisk will work with one or more investigator(s) and other experts who have contributed to 
the trial concept or design, acquisition, analysis or interpretation of data to report the results in one 
or more publications.
Authorship of publications should be in accordance with the Recommendations for the Conduct, 
Reporting, Editing and Publication of Scholarly Work in Medical Journals by the International 
Committee of Medical Journal Editors85.

All authors will be provided with the relevant statistical tables, figures, and reports needed to 
evaluate the planned publication. 
Where required by the journal, the investigator from each trial site will be named in an 
acknowledgement or in the supplementary material, as specified by the journal. 
Site-specific publication(s) by investigator(s)
For a multicentre clinical trial, analyses based on single-site data usually have significant statistical 
limitations and frequently do not provide meaningful information for healthcare professionals or 
subjects, and therefore may not be supported by Novo Nordisk. Thus, Novo Nordisk may deny a 
request or ask for deferment of the publication of individual site results until the primary manuscript 
is accepted for publication. In line with Good Publication Practice, such individual reports should 
not precede the primary manuscript and should always reference the primary manuscript of the trial.
Investigator access to data and review of results
As owner of the trial database, Novo Nordisk has the discretion to determine who will have access 
to the database.
Individual investigators will have their own subjects' data, and will be provided with the 
randomisation code after results are available.
8) Dissemination of clinical trial data
Information of the trial will be disclosed at clinicaltrials.gov and novonordisk-trials.com. It will also 
be disclosed according to other applicable requirements such as those of the International 
Committee of Medical Journal Editors86, the Food and Drug Administration Amendment Act 
(FDAAA)87, European Commission Requirements88, 89and other relevant recommendations or 
regulations. If a subject requests to be included in the trial via the Novo Nordisk e-mail contact at 
these web sites, Novo Nordisk may disclose the investigator’s contact details to the subject. As a 
result of increasing requirements for transparency, some countries require public disclosure of 
investigator names and their affiliations.
The Primary Completion Date (PCD) is the last assessment of the primary endpoint, and is for this 
trial Last Subject First Treatment + 68 weeks corresponding to ‘end of treatment’ visit. If the last 
subject is withdrawn early, the PCD is considered the date when the last subject would have 
completed ‘end of treatment’ visit. The PCD determines the deadline for results disclosure at 
clinicaltrials.gov according to FDAAA.

All subject data relating to the trial will be recorded on electronic CRFs unless transmitted 
electronically to Novo Nordisk or designee (e.g. laboratory data). The investigator is responsible 
for verifying that data entries are accurate and correct by physically or electronically signing the 
CRF. 
!
For some data both electronic and paper CRFs are used.
!
The following will be provided as paper CRFs:
!
Pregnancy forms
!
The following will be provided as paper CRFs to be used when access to the electronic CRF is 
revoked or temporarily unavailable: 
!
AE forms 
!
Safety information forms
!
Technical complaint forms (also to be used to report complaints that are not subject 
related, e.g. discovered at trial site before allocation)
!
Corrections to the CRF data may be made by the investigator or the investigator’s delegated 
staff. An audit trail will be maintained in the CRF application containing as a minimum: the old 
and the new data, identification of the person entering the data, date and time of the entry and 
reason for the correction. If corrections are made by the investigator’s delegated staff after the 
date when the investigator signed the CRF, the CRF must be signed and dated again by the 
investigator.
!
The investigator must ensure that data is recorded in the CRF as soon as possible, preferably 
within 5 working days after the visit. Once data has been entered, it will be available to Novo 
Nordisk for data verification and validation purposes.
Monitoring
!
The investigator must permit trial-related monitoring, audits, IRB/IEC review, and regulatory 
agency inspections and provide direct access to source data documents (original documents, 
data and records). Direct access includes permission to examine, analyse, verify and reproduce 
any record(s) and report(s) that are important to the evaluation of the trial. If the electronic 
medical record does not have a visible audit trail, the investigator must provide the monitor with 
signed and dated printouts. In addition the relevant trial site staff should be available for 
discussions at monitoring visits and between monitoring visits (e.g. by telephone). 
!
Trial monitors will perform ongoing source data verification to confirm that data entered into 
the CRF by authorised site personnel are accurate, complete and verifiable from source 
documents; that the safety and rights of subjects are being protected, to monitor drug 
accountability and collect completed paper CRF pages, if applicable, and that the trial is being 
conducted in accordance with the currently approved protocol and any other trial agreements, 
ICH GCP, and all applicable regulatory requirements.

Monitoring will be conducted using a risk based approach including risk assessment, monitoring 
plans, centralised monitoring (remote assessment of data by Novo Nordisk) and visits to trial 
sites. 
!
Monitors will review the subject’s medical records and other source data e.g. the diaries and 
mental health assessment instruments, to ensure consistency and/or identify omissions 
compared to the CRF. 
Protocol compliance
Deviations from the protocol should be avoided. If deviations do occur, the investigator must 
inform the monitor and the implications of the deviation must be reviewed and discussed.
Deviations must be documented and explained in a protocol deviation by stating the reason, date, 
and the action(s) taken. Some deviations, for which corrections are not possible, can be 
acknowledged and confirmed via edit checks in the CRF or via listings from the trial database. 
10) Source documents
!
All data entered in the CRF must be verifiable in source documentation other than the CRF.
!
The original of the completed diaries must not be removed from the trial site, unless they form 
part of the CRF and a copy is kept at the site. For food- and physical activity diary, if the subject 
uses an app or a tool other than the paper diaries, the medical record or dietician’s notes from 
the diet and physical activity counselling can be used as source document.
!
Source documents provide evidence for the existence of the subject and substantiate the 
integrity of the data collected. Source documents are filed at the trial site.
!
Data reported in the CRF that are transcribed from source documents must be consistent with 
the source documents or the discrepancies must be explained. The investigator may need to 
request previous medical records or transfer records. Also, current medical records must be 
available. 
!
It must be possible to verify subject’s medical history in the source documents such as subject’s 
medical record. 
!
Subjects completing electronic patient reported outcomes instruments are the data originators. 
Data will be transmitted to a technology service provider database, thus the service provider 
database is the source.
!
The investigator must document any attempt to obtain external medical information by noting 
the date(s) when information was requested and who was contacted.
!
Definition of what constitutes source data can be found in a source document agreement at each 
trial site. There will only be one source document defined at any time for any data element.

11) Retention of clinical trial documentation
!
Records and documents, including signed informed consent forms, pertaining to the conduct of 
this trial must be retained by the investigator for 15 years after end of trial unless local 
regulations or institutional policies require a longer retention period. No records may be 
destroyed during the retention period without the written approval of Novo Nordisk. No records 
may be transferred to another location or party without written notification to Novo Nordisk. 
!
The investigator must be able to access his/her trial documents without involving Novo Nordisk 
in any way. If applicable, electronic CRF and other subject data will be provided in an 
electronic readable format to the investigator before access is revoked to the systems and/or 
electronic devices supplied by Novo Nordisk. Site-specific CRFs and other subject data (in an 
electronic readable format or as paper copies or prints) must be retained by the trial site. If the 
provided electronic data (e.g. the CD-ROM) is not readable during the entire storage period, the 
investigator can request a new copy. A copy of all data will be stored by Novo Nordisk.
!
Subject’s medical records must be kept for the maximum period permitted by the hospital, 
institution or private practice
12) Trial and site closure
Novo Nordisk reserves the right to close the trial site or terminate the trial at any time for any 
reason at the sole discretion of Novo Nordisk. If the trial is suspended or terminated, the 
investigator must inform the subjects promptly and ensure appropriate therapy and follow-up. The 
investigator and/or Novo Nordisk must also promptly inform the regulatory authorities and 
IRBs/IECs and provide a detailed written explanation.
Trial sites will be closed upon trial completion. A trial site is considered closed when all required 
documents and trial supplies have been collected and a trial site closure visit has been performed.
The investigator may initiate trial site closure at any time, provided there is reasonable cause and 
sufficient notice is given in advance of the intended termination.
Reasons for the early closure of a trial site by Novo Nordisk or investigator may include but are not 
limited to:
!
failure of the investigator to comply with the protocol, the requirements of the IRB/IEC or local 
health authorities, Novo Nordisk procedures or GCP guidelines
!
inadequate recruitment of subjects by the investigator
!
discontinuation of further trial product development.
13) Responsibilities
The investigator is accountable for the conduct of the trial at his/her site and must ensure adequate 
supervision of the conduct of the trial at the trial site. If any tasks are delegated, the investigator 
must maintain a log of appropriately qualified persons to whom he/she has delegated specified trial-
related duties. The investigator must ensure that there is adequate and documented training for all

staff participating in the conduct of the trial. It is the investigator’s responsibility to supervise the 
conduct of the trial and to protect the rights, safety, and well-being of the subjects. 
A qualified physician, who is an investigator or a sub-investigator for the trial, must be responsible 
for all trial-related medical decisions. 
The investigator is responsible for filing essential documents (i.e. those documents which 
individually and collectively permit evaluation of the conduct of a trial and the quality of the da ta 
produced) in the investigator trial master file. The documents, including the subject identification 
code list must be kept in a secure locked facility so that no unauthorized persons can get access to 
the data. 
The investigator will take all necessary technical and organisational safety measures to prevent 
accidental or wrongful destruction, loss or deterioration of data. The investigator will prevent any 
unauthorised access to data or any other processing of data against applicable law. The investigator 
must be able to provide the necessary information or otherwise demonstrate to Novo Nordisk that 
such technical and organisational safety measures have been taken.
During any period of unavailability, the investigator must delegate responsibility for med ical care of 
subjects to a specific qualified physician who will be readily available to subjects during that time.
If the investigator is no longer able to fulfil the role as investigator (e.g. if he/she moves or retires) a 
new investigator will be appointed in consultation with Novo Nordisk. 
The investigator and other site personnel must have sufficient English skills according to their 
assigned task(s).
14) Indemnity statement 
Novo Nordisk carries product liability for its products, and liability as assumed under the special 
laws, acts and/or guidelines for conducting clinical trials in any country, unless others have shown 
negligence. 
Novo Nordisk assumes no liability in the event of negligence or any other liability of the sites or 
investigators conducting the trial or by persons for whom the said site or investigator are 
responsible. 
Novo Nordisk may pay additional costs incurred in relation to assessments relevant for following 
the safety of the subject. Investigator must contact Novo Nordisk on a case by case basis for 
whether the costs will be covered.

Adverse events: definitions and procedures for 
Appendix 4
recording, evaluation, follow-up, and reporting
AE definition
!
An AE is any untoward medical occurrence in a clinical trial subject that is temporally associated with the use of a 
medicinal product, whether or not considered related to the medicinal product.
!
An AE can be any unfavourable and unintended sign, including an abnormal laboratory finding, symptom or 
disease (new or exacerbated) temporally associated with the use of a medicinal product.
Events meeting the AE definition
!
Any abnormal laboratory test results or safety assessments, including those that worsen from baseline, considered 
clinically significant in the medical and scientific judgment of the investigator.
!
A CLAE: a clinical abnormal laboratory finding which is clinically significant, i.e. an abnormality that suggests a 
disease and/or organ toxicity and is of a severity that requires active management. Active management includes 
active treatment or further investigations, for example change of medicine dose or more frequent follow-up due to 
the abnormality.
!
Exacerbation of a chronic or intermittent pre-existing condition including either an increase in frequency and/or
intensity of the condition.
!
Signs, symptoms or the clinical sequelae of a suspected drug-drug interaction.
!
Signs, symptoms or the clinical sequelae of a suspected overdose of trial product regardless of intent.
!
A "lack of efficacy" or "failure of expected pharmacological action" per se will not be reported as an AE or SAE. 
Such instances will be captured in the efficacy assessments. However, the signs, symptoms and/or clinical sequelae 
resulting from lack of efficacy will be reported as AE or SAE if they fulfil the definition.
Events NOT meeting the AE definition 
!
Pre-existing conditions, anticipated day-to-day fluctuations of pre-existing conditions, including those identified 
during screening or other trial procedures performed before exposure to trial product. 
Note: pre-existing conditions should be recorded as medical history/concomitant illness.
!
Pre-planned procedures, unless the condition for which the procedure was planned has worsened from the first trial 
related activity after the subject has signed the informed consent.
Definition of an SAE
An SAE is an AE that fulfils at least one of the following criteria:
!
Results in death
!
Is life-threatening
!
The term 'life-threatening' in the definition of 'serious' refers to an event in which the subject was at risk of death at 
the time of the event. It does not refer to an event which hypothetically might have caused death, if it were more 
severe.
!
Requires inpatient hospitalisation or prolongation of existing hospitalisation
!
Hospitalisation signifies that the subject has been detained at the hospital or emergency ward for observation and/or 
treatment that would not have been appropriate in the physician’s office or outpatient setting. Complications that 
occur during hospitalisation are AEs. If a complication prolongs hospitalisation or fulfils any other serious criteria, 
the event is serious. When in doubt as to whether “hospitalisation” occurred or was necessary, the AE should be 
considered serious.
!
Hospitalisation for elective treatment of a pre-existing condition that did not worsen from baseline is not considered 
an AE.
Note:

Hospitalisations for administrative, trial related and social purposes do not constitute AEs and should therefore 
not be reported as AEs or SAEs.


Hospital admissions for surgical procedures, planned before trial inclusion, are not considered AEs or SAEs.
!
Results in persistent disability/incapacity
!
The term disability means a substantial disruption of a person’s ability to conduct normal life functions.
!
This definition is not intended to include experience of relatively minor medical significance such as 
uncomplicated headache, nausea, vomiting, diarrhoea, influenza, and accidental trauma (e.g. sprained ankle), which 
may interfere with or prevent everyday life functions but do not constitute a substantial disruption.
!
Is a congenital anomaly/birth defect
!
Important medical event:
!
Medical or scientific judgment should be exercised in deciding whether SAE reporting is appropriate in other 
situations. This includes important medical events that may not be immediately life-threatening or result in death or 
hospitalisation, but may jeopardise the subject or may require medical or surgical intervention to prevent one of the 
other outcomes listed in the above definition. These events should usually be considered serious and reported as 
SAEs using the important medical event criterion.
!
The following AEs must always be reported as SAEs using the important medical event criterion, if no other 
seriousness criteria are applicable:

suspicion of transmission of infectious agents via the trial product. 

risk of liver injury defined as ALT or AST >3 x UNL and total bilirubin >2 x UNL, where no alternative 
aetiology exists (Hy's law).
Description of AEs requiring additional data collection (via specific event form) and events for adjudication. 
AEs requiring additional data collection
AEs requiring additional data collection are AEs where the additional data will benefit the evaluation of the safety of 
the trial product (see Table 9-1). The selection of these events is based on the non-clinical and clinical data with 
semaglutide, knowledge from the GLP-1 RA drug class as well as regulatory requirements.
Event type
Description
Acute gallbladder disease
Events of symptomatic acute gallbladder disease (including gallstones and 
cholecystitis)
Acute pancreatitis
The diagnosis of acute pancreatitis requires two of the following three 
features:
1.
abdominal pain consistent with acute pancreatitis (acute onset of a 
persistent, severe, epigastric pain often radiating to the back)
2.
serum lipase activity (and/or amylase activity) at least three times 
greater than the upper limit of normal
3.
characteristic findings of acute pancreatitis on imaging.

UNL and total bilirubin > 2 x UNL, where no alternative aetiology exists 
(Hy's law), this must be reported as an SAE using the important medical 
event criterion if no other seriousness criteria are applicable.
Medication error: 
A medication error concerning trial products is defined as:
!
Administration of wrong drug.
!
Note: Use of wrong dispensing unit number (DUN) is not 
considered a medication error unless it results in a confirmed 
administration of wrong drug. 
!
Wrong route of administration, such as intramuscular instead of 
subcutaneous. 
!
Accidental administration of more than 2.4 mg/week or a higher dose 
than intended during dose escalation, however, the administered dose 
must deviate from the intended dose to an extent where clinical 
consequences for the trial subject were likely to happen as judged by 
the investigator, although they did not necessarily occur.

AE and SAE recording
!
The investigator will record all relevant AE/SAE information in the CRF.
!
The investigator will attempt to establish a diagnosis of the event based on signs, symptoms, and/or other clinical 
information. In such cases, the diagnosis (not the individual signs/symptoms) will be documented as the AE/SAE.
!
When an AE/SAE occurs, it is the responsibility of the investigator to review all documentation (e.g. hospital 
progress notes, laboratory and diagnostics reports) related to the event.
!
There may be instances when copies of source documents (e.g. medical records) for certain cases are requested by 
Novo Nordisk. In such cases, all subject identifiers, with the exception of the subject number, will be redacted on 
the copies of the source documents before submission to Novo Nordisk.
!
For all non-serious AEs the applicable forms should be signed when the event is resolved or at the end of the trial at 
the latest. For sign-off of SAE related forms refer to “SAE reporting via paper CRF” later in this section.
!
Novo Nordisk products used as concomitant medication: if an AE is considered to have a causal relationship with a 
Novo Nordisk marketed product used as concomitant medication in the trial, it is important that the suspected 
relationship is reported to Novo Nordisk, e.g. in the alternative aetiology section on the safety information form. 
Novo Nordisk may need to report this AE to relevant regulatory authorities.
Assessment of severity
The investigator will assess intensity for each event reported during the trial and assign it to one of the following 
categories: 
!
Mild: An event that is easily tolerated by the subject, causing minimal discomfort and not interfering with everyday 
activities.
!
Moderate: An event that causes sufficient discomfort and interferes with normal everyday activities.
!
Severe: An event that prevents normal everyday activities. 
Note: Severe is a category used for rating the intensity of an event; and both an AE and SAE can be assessed as 
severe. An event is defined as ‘serious’ when it meets at least one of the outcomes described in the definition of an 
SAE and not when it is rated as severe.

Assessment of causality
The investigator is obligated to assess the relationship between trial product and the occurrence of each AE/SAE.
Relationship between an AE/SAE and the relevant trial product(s) should be assessed as:
!
Probable - Good reason and sufficient documentation to assume a causal relationship.
!
Possible - A causal relationship is conceivable and cannot be dismissed.
!
Unlikely - The event is most likely related to aetiology other than the trial product.
Alternative aetiology, such as underlying disease(s), concomitant medication, and other risk factors, as well as the 
temporal relationship of the event to trial product administration will be considered and investigated.
The investigator should use the IB for the assessment. For each AE/SAE, the investigator must document in the medical 
records that he/she has reviewed the AE/SAE and has provided an assessment of causality.
There may be situations in which an SAE has occurred and the investigator has minimal information to include in the 
initial report. However, it is important that the investigator always makes an assessment of causality for every 
event before the initial transmission of the SAE data.
The investigator may change his/her opinion of causality in light of follow-up information and send a follow-up report 
with the updated causality assessment.
The causality assessment is one of the criteria used when determining regulatory reporting requirements.
Final outcome
The investigator will select the most appropriate outcome:
!
Recovered/resolved: The subject has fully recovered, or by medical or surgical treatment the condition has 
returned to the level observed at the first trial-related activity after the subject signed the informed consent.
!
Recovering/resolving: The condition is improving and the subject is expected to recover from the event. This term 
is only applicable if the subject has completed the trial or has died from another AE.
!
Recovered/resolved with sequelae: The subject has recovered from the condition, but with lasting effect due to a 
disease, injury, treatment or procedure. If a sequelae meets an SAE criterion, the AE must be reported as an SAE.
!
Not recovered/not resolved: The condition of the subject has not improved and the symptoms are unchanged or 
the outcome is not known.
!
Fatal: This term is only applicable if the subject died from a condition related to the reported AE. Outcomes of 
other reported AEs in a subject before he/she died should be assessed as “recovered/resolved”, 
“recovering/resolving”, “recovered/resolved with sequelae” or “not recovered/not resolved”. An AE with a fatal 
outcome must be reported as an SAE.
!
Unknown: This term is only applicable if the subject is lost to follow-up.
Follow-up of AE and SAE
The investigator is obligated to perform or arrange for the conduct of supplemental measurements and/or evaluations as 
medically indicated or as requested by Novo Nordisk to elucidate the nature and/or causality of the AE or SAE as fully 
as possible (e.g. severe hypersensitivity reactions). This may include additional laboratory tests (e.g. skin prick test) or 
investigations, histopathological examinations, or consultation with other health care professionals.
If a subject dies during participation in the trial or during a recognised follow-up period, the investigator should provide 
Novo Nordisk with a copy of autopsy report including histopathology.
New or updated information will be recorded in the CRF.

SAE reporting via electronic CRF
!
Relevant forms (AE and safety information form) must be completed in the CRF. 
!
For reporting and sign-off timelines (see box below). 
!
If the CRF is unavailable for more than 24 hours, then the site will use the paper AE form and if the CRF is 
unavailable for more than 5 calendar days then the site will use the paper safety information form (see box below).
!
The site will enter the SAE data into the CRF as soon as it becomes available, see Section 9.2.1.
!
After the trial is completed at a given site, the CRF will be decommissioned to prevent the entry of new data or 
changes to existing data. If a site receives a report of a new SAE from a subject or receives updated data on a 
previously reported SAE after CRF decommission, then the site can report this information on a paper AE and 
safety information form (see box below) or to Novo Nordisk by telephone.
SAE reporting via paper CRF
!
Relevant CRF forms (AE and safety information form) must be forwarded to Novo Nordisk either by fax, e-mail or 
courier.
!
Initial notification via telephone is acceptable, although it does not replace the need for the investigator to complete 
the AE and safety information form within the designated reporting time frames (as illustrated in Figure 9-1)
!
AE form within 24 hours.
!
Safety information form within 5 calendar days. 
!
Both forms must be signed within 7 calendar days.
Contact details for SAE reporting can be found in the investigator trial master file.

Appendix 5
information
It must be recorded in the CRF whether female subjects are of childbearing potential. 
Definitions
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming postmenopausal unless 
permanently sterile. 
Women in the following categories are not considered WOCBP
1. Premenarcheal 
2. Premenopausal female with one of the following:
!
Documented hysterectomy
!
Documented bilateral salpingectomy
!
Documented bilateral oophorectomy
Note: Documentation can come from the site personnel’s review of subject’s medical records, 
medical examination or medical history interview.
3. Postmenopausal female
!
. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal A 
postmenopausal state is defined as no menses for 12 months without an alternative medical 
cause. A high Follicle Stimulating Hormone (FSH) level in the postmenopausal range may 
be used to confirm a postmenopausal state in women not using hormonal contraception or 
Hormonal Replacement Therapy (HRT). However, in the absence of 12 months of 
amenorrhea, a single FSH measurement is insufficient. 
!
Females on HRT and whose menopausal status is in doubt will be required to use one of the 
non-hormonal highly effective contraception methods if they wish to continue their HRT 
during the trialstatus before trial enrolment.
Contraception guidance
Male subjects 
No contraception measures are required for male subjects as the risk of teratogenicity/fetotoxicity 
caused by transfer of semaglutide in seminal fluid is unlikely.
Female subjects
Female subjects of childbearing potential are eligible to participate if they agree to use methods of 
contraception consistently and correctly as described in table(s) below:

Vasectomised partner 
A vasectomised partner is a highly effective contraception method provided that the partner is the sole male sexual 
partner of the WOCBP and the absence of sperm has been confirmed. If not, an additional highly effective method of 
contraception should be used.
Sexual abstinence 
Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse 
during the entire period of risk associated with the trial product. The reliability of sexual abstinence needs to be 
evaluated in relation to the duration of the trial and the preferred and usual lifestyle of the subject.
Notes: 
aTypical use failure rates may differ from those when used consistently and correctly. Use should be consistent with 
local regulations regarding the use of contraceptive methods for subjects participating in clinical trials. 
bContraception should be utilised during the treatment period and for at least 49 days after the last dose of trial 
product.
In certain cases, it is accepted to use double barrier methods (a condom combined with an occlusive 
cap (e.g. diaphragm) with/without the use of spermicide). This should only be allowed in females 
with:
1) known intolerance to the highly effective methods mentioned in Table 11-5 or where the use of 
any of the listed highly effective contraceptive measures are contraindicated in the individual 
subject, and/or  
2) if the risk of initiating treatment with a specific highly effective method outweighs the benefit for 
the female.
Justification for accepting double barrier method should be at the discretion of the investigator 
taking into consideration his/hers knowledge about the female’s obesity history, concomitant

Pregnancy testing
!
WOCBP should only be included after a negative highly sensitive urine pregnancy test.
!
Urine pregnancy testing should be performed at every site visit every 4 or 8 weeks during the 
treatment period, at end of treatment and after the 7 weeks off-drug follow-up period according 
to the flowchart.
!
Additional urine pregnancy testing should be performed at monthly intervals during the 
treatment period, if required locally (Appendix 9).
!
Pregnancy testing should be performed whenever a menstrual cycle is missed or when 
pregnancy is otherwise suspected.
Collection of pregnancy information 
Female subjects who become pregnant 
!
Investigator will collect pregnancy information on any female subject, who becomes pregnant 
while participating in this trial.
!
Information will be recorded on the appropriate form and submitted to Novo Nordisk within 14 
calendar days of learning of a subject's pregnancy.
!
Subject will be followed to determine the outcome of the pregnancy. The investigator will 
collect follow-up information on subject and neonate, which will be forwarded to Novo 
Nordisk. Generally, follow-up will not be required for longer than 1 month beyond the delivery 
date.
!
Any termination of pregnancy will be reported, regardless of foetal status (presence or absence 
of anomalies) or indication for procedure.
!
While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication or 
elective termination of a pregnancy will be reported as an AE or SAE. 
!
A spontaneous abortion is always considered to be an SAE and will be reported as such.
!
Any SAE occurring as a result of a post-trial pregnancy which is considered possibly/probably 
related to the trial product by the investigator will be reported to Novo Nordisk as described in 
Appendix 4. While the investigator is not obligated to actively seek this information in former 
subjects, he or she may learn of an SAE through spontaneous reporting. 
Any female subject who becomes pregnant while participating in the trial will discontinue trial 
product.

Technical complaints: Definition and procedures for 
Appendix 6
recording, evaluation, follow-up and reporting
Technical complaint definition
A technical complaint is any written, electronic or oral communication that alleges product (medicine or device) 
defects. The technical complaint may be associated with an AE, but does not concern the AE itself.
Examples of technical complaints:
!
Problems with the physical or chemical appearance of trial products (e.g. discoloration, particles 
or contamination).
!
Problems with packaging material including labelling.
!
Problems related to medical devices (e.g. to the injection mechanism, dose setting mechanism,
dose button or interface between the pen-injector and the needle).
Time period for detecting technical complaints 
All technical complaints, which occur from the time of receipt of the product at trial site until the time of the last usage 
of the product, must be collected for products predefined on the technical complaint form. 
Reporting of technical complaints to Novo Nordisk
Contact details (fax, e-mail and address) for Customer Complaint Center – refer to Attachment I
Technical complaints must be reported on a separate technical complaint form:
1.
One technical complaint form must be completed for each affected DUN
2.
If DUN is not available, a technical complaint form for each batch, code or lot number must be completed
Timelines for reporting of technical complaints to Novo Nordisk
The investigator must complete the technical complaint form in the CRF within the timelines specified in Figure 9-3. 
If the CRF is unavailable or when reporting a technical complaint that is not subject related, the information must be 
provided on a paper form by fax, e-mail or courier to Customer Complaint Center, Novo Nordisk, within the same 
timelines as stated above. When the CRF becomes available again, the investigator must enter the information on the 
technical complaint form in the CRF.
Follow-up of technical complaints 
The investigator is responsible for ensuring that new or updated information will be recorded on the originally 
completed form. 
Collection, storage and shipment of technical complaint samples
The investigator must collect the technical complaint sample and all associated parts that were packed in the same DUN 
and notify the monitor within 5 calendar days of obtaining the sample at trial site. The sample and all associated parts 
must be sent as soon as possible to Customer Complaint Center, Novo Nordisk, together with a copy of the completed 
technical complaint form. The technical complaint sample should contain the batch, code or lot number and, if 
available, the DUN. If the technical complaint sample is unobtainable, the reason must be stated on the technical 
complaint form. If several samples are shipped in one shipment, the sample and the corresponding technical complaint 
form should be kept together.

Retention of human biosamples
Appendix 7
Antibody samples
!
Antibody samples will be retained for potential later analysis for further characterisation of 
antibody responses towards drug, if required by health authorities or for safety reasons.
!
Only Novo Nordisk staff and personnel from the specialised laboratory will have access to the 
stored specimens. 
!
The samples will be stored at the specialised laboratory or Novo Nordisk after end of trial and 
until marketing authorisation approval or until the research project terminates, but no longer 
than 15 years from end of trial after which they will be destroyed. 
!
Samples might be transferred to other countries, if not prohibited by local regulations. 
!
The subject’s identity will remain confidential and the samples will be identified only by subject 
number, visit number and trial identification number. No direct identification of the subject will 
be stored together with the samples. The analyses will not have any medical consequences for 
the subjects or their relatives. 
!
Subjects can contact the investigator if they wish to be informed about results derived from 
stored biosamples obtained from their own body.
Biosamples for future analysis
!
The trial will involve collection of human biosamples to be stored in a central archive.
!
Subjects must sign and date a separate informed consent form before biosamples are collected to 
be stored for future analysis.
!
The material to be collected is serum collected at baseline and end of treatment. A total of 5 
aliquots will be stored for each subject at both time points.
!
As new biomarkers related to the disease and/or safety, efficacy or mechanism of action of
semaglutide may evolve during the conduct of the trial, the analyses of the stored biosamples 
may also include biomarkers that are unknown at present or have not been included in the 
scientific hypotheses at initiation of the trial. 
!
The biosamples will be stored at a central laboratory for 6 months and at a central storage 
facility contracted by Novo Nordisk up to 15 years after end of trial. Only Novo Nordisk and 
storage facility employees will be able to access the stored biosamples. The biosamples may be 
transferred to other countries for analysis and will be destroyed at the latest 15 years after end of 
trial.
!
The subject may request the stored biosamples to be destroyed by withdrawing the designated
informed consent. 
!
The results obtained from any already performed analyses of the samples will still be used.
!
In the event that the collected biosamples (serum) will be used in the future, the investigator will 
become directly informed by Novo Nordisk about the results if the findings are deemed 
clinically relevant and analytically valid and quantifiable. In such case, a written summary of

Monitoring of calcitonin
Appendix 8
Background
Treatment with GLP-1 RAs has been shown to be associated with thyroid C-cell changes in rodents 
but not in non-human primates. The human relevance of this finding is unknown. However, based 
on the findings in rodents, monitoring of serum calcitonin (a sensitive biomarker for C-cell 
activation) is currently being performed in clinical trials with semaglutide.
While there is general agreement on the clinical interpretation of substantially elevat ed calcitonin 
levels (> 100 ng/L) as likely indicative of C-cell neoplasia, the interpretation of values between 
upper normal range (5.0 and 8.4 ng/L for women and men, respectively) and 100 ng/L is less clear 
with regards to indication of disease.
There are several known confounding factors affecting calcitonin levels, e.g.:
!
renal dysfunction
!
tobacco use
!
autoimmune thyroiditis
!
several drug classes (e.g. proton pump inhibitors, beta-blockers, H2-blockers and 
glucocorticoids)
Physiology of C-cell activation in various clinical conditions and in different patient populations 
(i.e. with various comorbidities) is poorly understood. There may be various clinical conditions not 
identified so far which mildly or moderately affect calcitonin secretion by C-cells.
Calcitonin monitoring
A blood sample will be drawn at pre-specified trial visits for measurement of calcitonin.
In case a subject has a calcitonin value ≥ 10 ng/L, the algorithm outlined in Figure 11-1 and 
described below should be followed. The algorithm applies for all calcitonin values in the trial.

Flow of calcitonin monitoring
Calcitonin ≥ 100 ng/L  
Action: The subject (even if a screen failure) must immediately be referred to a thyroid specialist 
for further evaluation and the trial product must be discontinued (see Section 8.1). The subject 
should remain in the trial; however, all medications suspected to relate to this condition must be 
discontinued until diagnosis has been established.
Background: These values were found in 9 (0.15%) of a population of 5817 patients with thyroid 
nodular disease90. All of these patients were diagnosed with MTC, resulting in a p ositive predictive 
value of 100%.
Diagnostic evaluation should include:

potentially, surgery with neck dissection
In case a subject is diagnosed with MTC, it is common clinical practice to explore the family 
history of MTC or MEN2 and perform a genetic test for RET proto-oncogene mutation.
Calcitonin ≥ 50 and < 100 ng/L
Action: The subject (even if a screen failure) should be referred to a thyroid specialist for further 
evaluation. The subject should remain in the trial and can continue on trial product.  
Background: These values were found in 8 (0.14%) of the population of 5817 patients with thyroid 
nodular disease90. Two of these subjects were diagnosed with MTC and two were diagnosed with C 
cell hyperplasia, resulting in a positive predictive value of a C-cell anomaly of 50%.
Diagnostic evaluation should include: 
!
thyroid ultrasound examination 
!
if available, and if there are no contraindications, a pentagastrin stimulation test should be done. 
For subjects with positive pentagastrin stimulation test, surgery should be considered. 
!
if pentagastrin stimulation test is not available, thyroid ultrasound and fine needle aspiration 
biopsy may add important clinical information about the need for surgery.
Calcitonin ≥ 10 and < 50 ng/L
Action: The subject can continue in the trial on trial product. Continue sampling of calcitonin 
according to the protocol.
If the subject is a screen failure, or if the value is from the last sample taken in the trial, the subject 
should be referred to a thyroid specialist for further evaluation.
Background: Calcitonin values from 20–50 ng/L were found in up to 1% of subjects of the 
population of 5817 patients with thyroid nodular disease 90. The predictive value of a C-cell anomaly 
for this calcitonin level was 8.3%. However, the likelihood of having a medullary carcinoma >1 cm 
with calcitonin in this range is extremely low.
For calcitonin values between 10-20 ng/L Costante et al.90 identified 216 (3.7%) patients. One 
patient out of the 216 had a subsequent basal (unstimulated) calcitonin value of 33 ng/L, and had C-
cell hyperplasia at surgery. Two other studies used a cut-off of calcitonin > 10 ng/L to screen for C-
cell disease, but they do not provide sufficient information on patients with basal CT > 10 and < 20 
ng/L to allow conclusions91, 92.

For Japan and Taiwan: age ≥ 20 years at the time of signing informed consent
Section 6.2 Exclusion criterion no. 29
Female who is pregnant, breast-feeding or intends to become pregnant or is of child-bearing 
potential and not using adequate contraceptive methods (highly effective contraceptive measures as 
required by local regulation or practice) 
For Belgium: highly effective methods of birth control are defined as those, alone or in 
combination, that result in a low failure rate (i.e., less than 1% per year) when used consistently and 
correctly; such as implants, injectables, combined oral contraceptives, some IUDs, true sexual 
abstinence (i.e. refraining from heterosexual intercourse during the entire period of risk associated 
with the study treatments) or vasectomised partner.
For Denmark: Contraceptive measures considered adequate include intrauterine devices or 
hormonal contraception (oral contraceptive pills, implants, transdermal patches, vaginal rings or 
long-acting injections).
For Argentina: the following contraceptive measures are considered adequate: barrier methods 
(condoms or diaphragm) with spermicide, contraceptive pills or intrauterine device (IUD). The 
contraceptive methods will be reimbursed by the sponsor.
Section 7.5 Preparation/Handling/Storage/Accountability
For Japan: according to Japanese GCP, storage and drug accountability of the trial products at the 
study site is not in charge of Investigator, but in charge of the head of study site. 
The head of study site should assign some or all of the responsibilities for accountability of the trial 
products at the sites to a trial product storage manager (a pharmacist in principle). The trial product 
storage manager should control and take accountability of the trial products in accordance with 
procedures specified by the sponsor. The head of study site or the trial product storage manager 
must ensure the availability of proper storage conditions, and record and evaluate the temperature.
For India: In-use conditions will be available on the Trial Material Manual.

Introduction including rationale for the protocol amendment
This protocol is amended for the following reasons:
!
To implement genetic biosamples for future analysis for those countries where it will be 
applicable.
The rationale for implementation is to ensure a better characterisation of the population in 
scope as new technologies and hypothesis develops. The collection of whole blood at 
baseline (visit 2) and end of treatment (visit 24) will allow for future genetic analysis 
thereby increasing the understanding of obesity, obesity treatment and related diseases in the 
future.
!
As the scope of the biosampling for future analysis has broadened to cover obesity and -
related diseases with this amendment, some paragraphs in appendix 7 have been revised. 
Furthermore, the informed consent has been updated to reflect the broader scope. A separate 
protocol will be developed before the biosamples from NN9536-4373 can be analysed in the 
future. This will include rationale for the analysis as well as reporting requirements.
!
Removal of criteria for discontinuation of trial treatment for subjects included in the trial in 
violation of the inclusion and/or exclusion criteria and/or randomisation criteria. Subjects 
will not be discontinued from trial product if considered safe to continue. However, 
prospective approval of protocol deviations to recruitment and enrolment criteria, also 
known as protocol waivers or exemptions, is not permitted and deviations from the protocol 
should be avoided.
!
Classifications of risks have been removed from the protocol and instead a reference to the 
IB or any updates hereof has been added for further details of the risks associated with 
semaglutide treatment.
!
Minor clarification of content and correction of minor errors and typos.

Section 3.2 
Background
2.2.1
Section 3.2.1 Semaglutide
GLP-1 RA is a physiological regulator of appetite and GLP-1 receptors are present in several areas 
of the brain involved in appetite regulation56.
Clinical58-623 and non-clinical data 6364 indicate that the body weight-reducing effect of semaglutide 
is mainly mediated by a reduced energy intake. No unexpected safety findings were identified and 
the tolerability and safety profile was overall consistent with previous findings in the T2D 
development programme and the GLP-1 RA class in general.
2.2.2
3.2.2 
Trial population
The trial population will consist of subjects with obesity (BMI > ≥30 kg/m2) or with overweight
(BMI > ≥27 kg/m2) and weight-related comorbidities.
2.3
3.3 Benefit-risk assessment
2.3.1
3.3.2 
Risks and precautions
The sections below describe identified and potential risks associated with semaglutide treatment. 
For classification and further details of the risks, please refer to the current version of the IB or any 
updates hereof. The identified/potential risks are based on findings in non-clinical studies and 
clinical trials with semaglutide as well as other GLP-1 RAs. For each of these risks, mitigating 
actions have been implemented to minimise the risks for subjects enrolled in this trial.
Identified risks
Gastrointestinal adverse events
!
Consistent with findings with other GLP-1 RAs, the most frequently reported adverse
events (AE) in clinical trials with semaglutide were gastrointestinal AEs. A low starting 
dose and dose escalation steps will be implemented in the trial to mitigate the risk of 
gastrointestinal AEs.
Potential risks
Medullary thyroid cancer (MTC) (based on non-clinical data)
!
Expected proliferative thyroid C-cell changes were seen in the mouse and rat
carcinogenicity studies after daily exposure to semaglutide for 2 years. No hyperplasia was 
observed in monkeys after 52 weeks exposure up to 13-fold above the clinical plasma
exposure at 2.4 mg/week. In clinical trials with semaglutide, there have been no reports of 
MTC or clinically relevant changes in calcitonin levels. The C-cell changes in rodents are 
mediated by the GLP-1 receptor, which is not expressed in the normal human thyroid.

Accordingly, the risk of GLP-1 receptor-mediated C-cell changes in humans is considered 
to be low. However, as a precaution, exclusion and discontinuation criteria related to 
medical history of multiple endocrine neoplasia type 2 (MEN2) or MTC and elevated 
plasma levels of calcitonin (biomarker for MTC) have been implemented in the trial.
Other risks
Pregnancy and fertility (based on non-clinical data)
!
Studies in animals have shown reproductive toxicity. There are limited data from the use of 
semaglutide in pregnant women. Therefore, semaglutide should not be used during 
pregnancy. Exclusion and discontinuation criteria related to pregnancy have been
implemented in the trial.
2.4
Section 7.1 
Treatments administered
!
Injections may be administered in the thigh, abdomen or upper arm, at any time of day
irrespective of meals. Subjects should be encouraged to inject in the same area throughout 
the trial, but changing between left and right side is allowed.

Section 8 
Discontinuation/Withdrawal criteria
2.5.1
Section 8.1 
Discontinuation of trial treatment
The subject must be discontinued from trial product, if any of the following applies:
1. Included in the trial in violation of the inclusion and/or exclusion criteria and/or randomisation
criteria
2 1. Safety concern as judged by the investigator
3.2. Calcitonin ≥ 100 ng/L (see Appendix 8)
4 3. Suspicion of pancreatitis
5.4. Pregnancy
6.5. Intention of becoming pregnant
7.6. Simultaneous participation in another clinical trial of an approved or non-approved
Investigational medicinal product.
Subjects meeting discontinuation of trial product criterion no. 4 3 are allowed to resume trial 
product if the Atlanta criteria71 are not fulfilled and thus the suspicion of acute pancreatitis is not 
confirmed.
Trial product may be resumed for subjects with a gallstone-induced pancreatitis in case of 
cholecystectomy.
Subjects meeting discontinuation of trial product criteria no. 2 1, 5 4 and 6 5 are allowed to resume 
trial product, if the criteria are no longer met (see Section 8.1.1).

Genetics
Not applicable for this trial.
A blood sample for genetic analysis will be collected from subjects who have consented to

further details.
2.7
Section 9.8 
Biomarkers and biosamples for future analysis
Collection of samples for biomarker research is part of this trial to support the efficacy objectives. 
The following samples must be collected in accordance with the laboratory manual and the 
flowchart:
Biomarkers linked to cardiovascular risk:
!
Plasminogen Activator Inhibitor-1 (PAI-1) Activity will be analysed by activity assay.
!
High sensitive C-reactive protein (hsCRP)
Collection of biosamples for future analysis (stored in a biobank) is a component of this trial. 
Participation in the biobank component is optional. Subjects who do not wish to participate in the 
biobank component may still participate in the trial. For the biobank, samples will be collected 
according to the flowchart and stored for future use.
The samples are collected for the purpose of allowing future analyses of biomarkers, both genetic 
and circulating, at a later point in time when new knowledge or improved measurement techniques 
may have become available. The analyses may include biomarkers currently known or discovered 
in the future.
Genetic analyses may include analysis of candidate genes or genetic markers throughout the 
genome with the purpose of understanding and predicting response to semaglutide as well as to 
understand obesity or other related diseases.
Analyses of circulating biomarkers will measure hormones, metabolites or other non-genetic  serum 
entity with the purpose of understanding and predicting response to semaglutide as well as 
understanding obesity or other related diseases.
These samples need to be frozen and should be sent in batches to the central laboratory. The 
analyses are likely to be performed after the trial has come to an end, and results will therefore not 
be part of the clinical trial report. The biobank samples may be stored up to 15 years after end of 
trial at a central laboratory (see Appendix 7).

Biosamples for future analysis
In countries where applicable, the trial will involve collection of human biosamples to be stored in 
a central archive for future use.
The material to be collected is serum collected at baseline (visit 2) and end of treatment (visit 24) is:
A total of 5 aliquots will be stored for each subject at both time points.
!
Whole blood (for genetic analysis)
!
Serum (for analyses of circulating biomarkers)
The results obtained from any already performed analyses of the samples will still be used.
In the event that the collected biosamples (serum) will be used in the future, the investigator will
become directly informed by Novo Nordisk about the results if the findings are deemed clinically 
relevant and analytically valid and quantifiable. In such case, a written summary of the findings, 
including listings of subject specific values, will be provided once a firm conclusion from the 
results has been drawn by Novo Nordisk.
Potentially, observations of neoplastic diseases, serious hereditary diseases, other un-treatable
diseases, or any other abnormal findings could be part of the observations. Subjects can contact the 
investigator if they wish to be informed about results derived from stored biosamples obtained from 
their own body.
In case the subject withdraws his/her informed consent for biosamples for future analysis and 
genetics, the monitor must contact the trial manager at Novo Nordisk as soon as possible in order 
to have the samples withdrawn from storage.

Introduction including rationale for the protocol amendment
This protocol is amended for the following reasons:
!
To implement genetic biosamples for future analysis for those countries where it will be 
applicable.
The rationale for implementation is to ensure a better characterisation of the population in scope as 
new technologies and hypothesis develops. The collection of whole blood at baseline (visit 2) and 
end of treatment (visit 24) will allow for future genetic analysis thereby increasing the 
understanding of obesity, obesity treatment and related diseases in the future.
!
As the scope of the biosampling for future analysis has broadened to cover obesity and -
related diseases with this amendment, some paragraphs in appendix 7 have been revised. 
Furthermore, the informed consent has been updated to reflect the broader scope. A separate 
protocol will be developed before the biosamples from NN9536-4373 can be analysed in the 
future. This will include rationale for the analysis as well as reporting requirements.

GLP-1 RA is a physiological regulator of appetite and GLP-1 receptors are present in several areas 
of the brain involved in appetite regulation56.
Clinical58-623 and non-clinical data 6364 indicate that the body weight-reducing effect of semaglutide 
is mainly mediated by a reduced energy intake. No unexpected safety findings were identified and

Risks and precautions
The sections below describe identified and potential risks associated with semaglutide treatment. 
For classification and further details of the risks, please refer to the current version of the IB or any 
updates hereof. The identified/potential risks are based on findings in non-clinical studies and 
clinical trials with semaglutide as well as other GLP-1 RAs. For each of these risks, mitigating 
actions have been implemented to minimise the risks for subjects enrolled in this trial.
Identified risks
Gastrointestinal adverse events
!
Consistent with findings with other GLP-1 RAs, the most frequently reported adverse 
events (AE) in clinical trials with semaglutide were gastrointestinal AEs. A low starting 
dose and dose escalation steps will be implemented in the trial to mitigate the risk of 
gastrointestinal AEs.
Potential risks
Medullary thyroid cancer (MTC) (based on non-clinical data)
!
Expected proliferative thyroid C-cell changes were seen in the mouse and rat 
carcinogenicity studies after daily exposure to semaglutide for 2 years. No hyperplasia 
was observed in monkeys after 52 weeks exposure up to 13-fold above the clinical 
plasma exposure at 2.4 mg/week. In clinical trials with semaglutide, there have been no 
reports of MTC or clinically relevant changes in calcitonin levels. The C-cell changes in 
rodents are mediated by the GLP-1 receptor, which is not expressed in the normal 
human thyroid. Accordingly, the risk of GLP-1 receptor-mediated C-cell changes in 
humans is considered to be low. However, as a precaution, exclusion and 
discontinuation criteria related to medical history of multiple endocrine neoplasia type 2 
(MEN2) or MTC and elevated plasma levels of calcitonin (biomarker for MTC) have 
been implemented in the trial.

Pregnancy and fertility (based on non-clinical data)
!
Studies in animals have shown reproductive toxicity. There are limited data from the use 
of semaglutide in pregnant women. Therefore, semaglutide should not be used during 
pregnancy. Exclusion and discontinuation criteria related to pregnancy have been 
implemented in the trial.

Section 9.8 
Biomarkers and biosamples for future analysis
Collection of samples for biomarker research is part of this trial to support the efficacy objectives. 
The following samples must be collected  in accordance with the laboratory manual and the 
flowchart:
Biomarkers linked to cardiovascular risk:
Plasminogen Activator Inhibitor-1 (PAI-1) Activity will be analysed by activity assay.
High sensitive C-reactive protein (hsCRP)
Collection of biosamples for future analysis (stored in a biobank) is a component of this trial. 
Participation in the biobank component is optional. Subjects who do not wish to participate in the 
biobank component may still participate in the trial. For the biobank, samples will be collected 
according to the flowchart and stored for future use.
The samples are collected for the purpose of allowing future analyses of biomarkers, both genetic 
and circulating, at a later point in time when new knowledge or improved measurement techniques 
may have become available. The analyses may include biomarkers currently known or discovered 
in the future.
Genetic analyses may include analysis of candidate genes or genetic markers throughout the 
genome with the purpose of understanding and predicting response to semaglutide as well as to 
understand obesity or other related diseases.

Analyses of circulating biomarkers will measure hormones, metabolites or other non-genetic  serum 
entity with the purpose of understanding and predicting response to semaglutide as well as 
understanding obesity or other related diseases.
These samples need to be frozen and should be sent in batches to the central laboratory. The 
analyses are likely to be performed after the trial has come to an end, and results will therefore not 
be part of the clinical trial report. The biobank samples may be stored up to 15 years after end of

Biosamples for future analysis
In countries where applicable, the trial will involve collection of human biosamples to be stored in 
a central archive for future use.
The material to be collected is serum collected at baseline (visit 2) and end of treatment (visit 24) is:
A total of 5 aliquots will be stored for each subject at both time points.
Whole blood (for genetic analysis)
Serum (for analyses of circulating biomarkers)
The results obtained from any already performed analyses of the samples will still be used.
In the event that the collected biosamples (serum) will be used in the future, the investigator will 
become directly informed by Novo Nordisk about the results if the findings are deemed clinically 
relevant and analytically valid and quantifiable. In such case, a written summary of the findings, 
including listings of subject specific values, will be provided once a firm conclusion from the 
results has been drawn by Novo Nordisk. 
Potentially, observations of neoplastic diseases, serious hereditary diseases, other un-treatable 
diseases, or any other abnormal findings could be part of the observations. Subjects can contact the 
investigator if they wish to be informed about results derived from stored biosamples obtained from 
their own body.
In case the subject withdraws his/her informed consent for biosamples for future analysis and 
genetics, the monitor must contact the trial manager at Novo Nordisk as soon as possible in order 
to have the samples withdrawn from storage.

Introduction including rationale for the protocol amendment
This protocol is amended for the following reasons:
!
To implement genetic biosamples for future analysis for those countries where it will be 
applicable.
The rationale for implementation is to ensure a better characterisation of the population in 
scope as new technologies and hypothesis develops. The collection of whole blood at 
baseline (visit 2) and end of treatment (visit 24) will allow for future genetic analysis 
thereby increasing the understanding of obesity, obesity treatment and related diseases in the 
future.
!
As the scope of the biosampling for future analysis has broadened to cover obesity and -
related diseases with this amendment, some paragraphs in appendix 7 have been revised. 
Furthermore, the informed consent has been updated to reflect the broader scope. A separate 
protocol will be developed before the biosamples from NN9536-4373 can be analysed in the 
future. This will include rationale for the analysis as well as reporting requirements.
!
Classifications of risks have been removed from the protocol and instead a reference to the 
IB or any updates hereof has been added for further details of the risks associated with 
semaglutide treatment.
!
Minor clarification of content and correction of minor errors and typos.

Risks and precautions
The sections below describe identified and potential risks associated with semaglutide treatment. 
For classification and further details of the risks, please refer to the current version of the IB or any 
updates hereof. The identified/potential risks are based on findings in non-clinical studies and 
clinical trials with semaglutide as well as other GLP-1 RAs. For each of these risks, mitigating 
actions have been implemented to minimise the risks for subjects enrolled in this trial.
Identified risks
Gastrointestinal adverse events
!
Consistent with findings with other GLP-1 RAs, the most frequently reported adverse
events (AE) in clinical trials with semaglutide were gastrointestinal AEs. A low starting 
dose and dose escalation steps will be implemented in the trial to mitigate the risk of 
gastrointestinal AEs.
Potential risks
Medullary thyroid cancer (MTC) (based on non-clinical data)
!
Expected proliferative thyroid C-cell changes were seen in the mouse and rat
carcinogenicity studies after daily exposure to semaglutide for 2 years. No hyperplasia was 
observed in monkeys after 52 weeks exposure up to 13-fold above the clinical plasma
exposure at 2.4 mg/week. In clinical trials with semaglutide, there have been no reports of 
MTC or clinically relevant changes in calcitonin levels. The C-cell changes in rodents are 
mediated by the GLP-1 receptor, which is not expressed in the normal human thyroid. 
Accordingly, the risk of GLP-1 receptor-mediated C-cell changes in humans is considered 
to be low. However, as a precaution, exclusion and discontinuation criteria related to 
medical history of multiple endocrine neoplasia type 2 (MEN2) or MTC and elevated 
plasma levels of calcitonin (biomarker for MTC) have been implemented in the trial.

Introduction including rationale for the protocol amendment
This protocol is amended for the following reasons:
!
To extend the trial for an additional 45-weeks off-treatment period after the last visit in the 
main phase (i.e. V25) without structured lifestyle intervention in the following countries 
only: Canada, Germany, the UK and selected sites in the US and Japan. 
The rationale for extending the trial is to obtain a better understanding of how the weight, 
cardiovascular risk factors and glucose metabolism develops after completed 
pharmacotherapy intervention in people living with overweight or obesity. The extension of 
this trial mimics a real world setting and can thereby provide better guidance to health care 
professionals in the future management of people living with obesity as well as to these
people. 
Separate Clinical Trial Reports (CTR) will be prepared for the main and the extension phase 
of the trial.
!
Addition of “Main phase” and “Extension phase” throughout the protocol to highlight 
which sections are related to the “main phase” and which are related to the “extension 
phase”. The protocol described the main phase in all sections unless it is explicitly 
described as referring to the extension phase.
!
Minor clarification of content and correction of minor errors and typos.
In the following, the changes related to all countries are listed first in Section 2 followed by the 
changes related to the countries participating in the extension phase in Section 3.

2.2.1
Section 3.2
Background
2.2.1.1
Section 3.2.1 
Semaglutide 
Clinical589-634 and non-clinical data645 indicate that the body weight-reducing effect of semaglutide 
is mainly mediated by a reduced energy intake. No unexpected safety findings were identified and 
the tolerability and safety profile was overall consistent with previous findings in the T2D 
development programme and the GLP-1 RA class in general.

characterised for in vitro neutralising effect towards semaglutide. In addition, if samples taken at the 
‘end of trial’ visit are also positive for cross-reactivity against endogenous GLP-1, the samples will 
be analysed for in vitro neutralising effect towards endogenous GLP-1. Samples which are positive 
for anti-semaglutide antibodies will also be titrated. The results of the analysis will only be 
disclosed after completion of the clinical trial report (CTR) if required by local regulation.

Section 9.8
Biomarkers and biosamples for future analysis
Collection of samples for biomarker research is part of this trial to support the effect objectives. The 
following samples must be conducted in accordance with the laboratory manual and the flowchart:
Biomarkers linked to cardiovascular risk:
!
Plasminogen Activator Inhibitor (PAI-1) Activity will be analysed by activity assay.
!
High sensitive C-reactive protein (hsCRP)
Biomarkers linked to hunger and satiety:
!
Leptin 
!
Soluble leptin receptor
Collection of biosamples for future analysis (stored in a biobank) is a component of this trial. 
Participation in the biobank component is optional. Subjects who do not wish to participate in the 
biobank component may still participate in the trial. For the biobank, samples will be collected 
according to the flowchart and stored for future use.
The samples are collected for the purpose of allowing future analyses of biomarkers, both genetic 
and circulating, at a later point in time when new knowledge or improved measurement techniques 
may have become available. The analyses may include biomarkers currently known or discovered 
in the future.
Genetic analyses may include analysis of candidate genes or genetic markers throughout the 
genome with the purpose of understanding and predicting response to semaglutide as well as to 
understand obesity or other related diseases.
Analyses of circulating biomarkers will measure hormones, metabolites or other non-genetic serum 
entity with the purpose of understanding and predicting response to semaglutide as well as 
understanding obesity or other related diseases.
These samples need to be frozen and should be sent in batches to the central laboratory. The 
analyses are likely to be performed after the trial has come to an end, and results will therefore not 
be part of the clinical trial report. The biobank samples may be stored up to 15 years after end of 
trial at a central laboratory (see Appendix 7).

Medication error: 
A medication error concerning trial products is defined as:
!
Administration of wrong drug.
!
Note: Use of wrong dispensing unit number (DUN) is not 
considered a medication error unless it results in a confirmed 
administration of wrong drug. 
!
Wrong route of administration, such as intramuscular instead of 
subcutaneous. 
!
Accidental administration of more than 2.4 mg/week or a higher dose 
than intended during dose escalation, however, the administered dose 
must deviate from the intended dose to an extent where clinical 
consequences for the trial subject were likely to happen as judged by 
the investigator, although they did not necessarily occur.
!
Administration of an overdose with the intention to cause harm, 
misuse or abuse of trial product.
Misuse or abuse of trial 
product*
!
Misuse is when the trial product is intentionally and inappropriately 
used. Abuse of trial product is persistent or sporadic, intentional 
excessive use, which is accompanied by harmful physical or 
psychological effects (e.g. overdose with the intention to cause harm).
*Additional data for misuse or abuse of trial product is reported on the medication error event 
form.

Contraceptive guidance and collection of pregnancy information
2.7.1
Women in the following categories are not considered WOCBP 
2.7.1.1
3. Postmenopausal female
!
. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal A 
postmenopausal state is defined as no menses for 12 months without an alternative medical 
cause. A high Follicle Stimulating Hormone (FSH) level in the postmenopausal range may 
be used to confirm a postmenopausal state in women not using hormonal contraception or 
Hormonal Replacement Therapy (HRT). However, in the absence of 12 months of 
amenorrhea, a single FSH measurement is insufficient. 
!
Females on HRT and whose menopausal status is in doubt will be required to use one of the 
non-hormonal highly effective contraception methods if they wish to continue their HRT 
during the trialstatus before trial enrolment. Otherwise, they must discontinue HRT to allow 
confirmation of postmenopausal status before trial enrolment.

Collection of pregnancy information
2.7.3.1
Female subjects who become pregnant
!
Investigator will collect pregnancy information on any female subject, who becomes pregnant 
while participating in this trial.
!
Information will be recorded on the appropriate form and submitted to Novo Nordisk within 14 
calendar days of learning of a subject's pregnancy.
!
Subject will be followed to determine the outcome of the pregnancy. The investigator will 
collect follow-up information on subject and neonate, which will be forwarded to Novo 
Nordisk. Generally, follow-up will not be required for longer than 1 month beyond the delivery 
date.
!
Any termination of pregnancy will be reported, regardless of foetal status (presence or absence 
of anomalies) or indication for procedure.
!
While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication or 
elective termination of a pregnancy for medical reasons will be reported as an AE or SAE. 
!
A spontaneous abortion is always considered to be an SAE and will be reported as such.
!
Any SAE occurring as a result of a post-trial pregnancy which is considered possibly/probably 
related to the trial product by the investigator will be reported to Novo Nordisk as described in 
Appendix 4. While the investigator is not obligated to actively seek this information in former
subjects, he or she may learn of an SAE through spontaneous reporting

The local requirement on 
contraceptive methods in Appendix 9 
in the protocol is less strict than the
global requirements in Appendix 5, 
i.e. barrier methods are not allowed 
in this trial, therefore the local 
requirement is deleted and Appendix 
5 must be followed in Argentina.
Required by local regulation
The amendment was superseded by commitment letter from the Sponsor.

Section 1 
Synopsis
3.1.1
Rationale
Extension phase 
The rationale for extending the trial is to obtain a better understanding of how the weight, 
cardiovascular risk factors and glucose metabolism develops after completed pharmacotherapy 
intervention in people living with overweight or obesity. The extension of this trial mimics a real 
world setting and can thereby provide better guidance to health care professionals in the future 
management of people living with obesity as well as to these people. Focus in the off-treatment 
extension phase is change in body weight, cardiovascular risk factors and glucose metabolism in a 
subset of subjects who have completed the main phase on the target dose of 2.4 mg semaglutide 
once-weekly or semaglutide placebo as an adjunct to a reduced-calorie diet and increased physical 
activity. 
The 2.4 mg dose has been selected as an inclusion criterion in the extension phase as this is the 
target dose in the main phase of NN9536-4373 as outlined in Section 5.5. 
3.1.2
Overall design
Extension phase 
The extension phase is a 45-week off-treatment period after the last visit in the main phase (i.e. 
V25) without structured lifestyle intervention. Subjects on the target dose of 2.4 mg semaglutide 
once-weekly or semaglutide placebo at the End of Treatment visit (V24) are considered eligible and 
will be offered continued follow-up at the investigational site for an additional 45 weeks. For 
subjects continuing in the extension phase, the total trial duration will be approximately 122 weeks 
(2 weeks screening, 68 weeks treatment and 52 weeks observation). The extension phase includes 5 
visits to the clinic (week 68, 75, 80, 104 and week 120); the first two visits of the extension phase 
(V24ext and V25ext) coincide with the visits (V24 and V25) in the main phase of the trial.

Benefits
Extension phase
Subjects who continue in the extension phase are expected to benefit from the continued contact 
with the trial site focusing on general health, including body weight, cardiovascular risk factors 
and glucose metabolism parameters. As the extension is an off-treatment period, there are no risks 
considered to the subjects’ participation.

phase and the Subject Information and Informed Consent will be presented to the subject, followed 
by the week 75 visit where the first extension parameters will be collected (if subject has accepted 
participation). The first two visits in the extension phase (V24ext and V25ext) coincide with the visits 
(V24 and V25) in the main phase of the trial. For subjects continuing in the extension phase, the 
total trial duration will be approximately 122 weeks (2 weeks screening, 68 weeks treatment, 52

Lost to follow-up
Extension phase
Efforts must be made to have the subjects, who agree to participate in the extension phase, also to 
continue in the extension phase. Subjects must be educated about the continued scientific 
importance of their data. Only subjects who withdraw consent will be considered as withdrawn 
from the extension phase of the trial. 
A subject may withdraw consent at any time during the extension phase at his/her own request as 
described for the main phase in Section 8.2. If a subject is lost to follow-up all efforts should be 
made as described in Section 8.3 for the main phase.

Adverse events
Extension phase
No systematic collection of AEs or SAEs will be performed, meaning investigators are not obliged 
to actively seek for AE or SAEs in trial subjects after the week 75 visit (V25); 7 weeks after last trial 
product administration. 
If the investigator learns of any SAE, including death, at any time after week 75, and the 
investigator considers the event to be possibly/probably related to the investigational product or 
trial participation, the investigator must promptly notify Novo Nordisk by completing a paper AE-
and Safety Information Form as described in Appendix 4; SAE reporting via paper CRF. 
Adverse reactions associated with other products, including marketed Novo Nordisk products, 
should be reported via the national spontaneous reporting system to either the local competent 
authority or the marketing authorisation holder directly.
