Summary
Objectives and endpoints:
Primary objective
To compare the effect of once-daily dosing of 14 mg oral semaglutide versus placebo, both in 
combination with metformin and/or sulfonylurea, basal insulin alone or metformin in combination 
with basal insulin on glycaemic control in subjects with type 2 diabetes mellitus and moderate renal 
impairment.
Secondary objectives
To compare the effect of once-daily dosing of 14 mg oral semaglutide versus placebo, both in 
combination with metformin and/or sulfonylurea, basal insulin alone or metformin in combination 
with basal insulin on body weight in subjects with type 2 diabetes mellitus and moderate renal 
impairment.
To compare the safety and tolerability of once-daily dosing of 14 mg oral semaglutide versus 
placebo, both in combination with metformin and/or sulfonylurea, basal insulin alone or metformin 
in combination with basal insulin in subjects with type 2 diabetes mellitus and moderate renal 
impairment.
Primary endpoint
Change from baseline to week 26 in glycosylated haemoglobin (HbA1c).
Key secondary endpoints
Change from baseline to week 26 in body weight (kg).
Change from baseline to week 26 in fasting plasma glucose.
If a subject after week 26 achieves (yes/no):
!
HbA1c < 7.0% (53 mmol/mol) American Diabetes Association target.
Number of treatment-emergent adverse events during exposure to trial product, assessed up to 
approximately 31 weeks.
Number of treatment-emergent severe or blood glucose-confirmed symptomatic hypoglycaemic 
episodes during exposure to trial product, assessed up to approximately 31 weeks.

Trial design:
This is a 26-week, randomised, double-blind, placebo-controlled, parallel-group, multicentre, 
multinational trial with 2 arms comparing the efficacy and safety of oral semaglutide with placebo 
in subjects with type 2 diabetes mellitus and moderate renal impairment.
Subjects will be randomised 1:1 to receive one of the following treatments:
!
14 mg oral semaglutide once-daily
!
placebo once-daily
The total trial duration for the individual subject will be approximately 33 weeks. The trial includes 
a 2-week screening period, followed by a 26-week randomised treatment period and a follow-up 
period of 5 weeks.
Trial population:
Number of subjects planned to be randomised: 324
Inclusion criteria:
!
Informed consent obtained before any trial-related activities. Trial-related activities are any 
procedures that are carried out as part of the trial, including activities to determine suitability for 
the trial.
!
Male or female, age above or equal to 18 years at the time of signing informed consent. 
!
Diagnosed with type 2 diabetes mellitus ≥ 90 days prior to day of screening.
!
HbA1c of 7.0-9.5% (53-80 mmol/mol) (both inclusive).
!
Moderate renal impairment defined as estimated glomerular filtration rate of 
30-59 mL/min/1.73 m2 as per Chronic Kidney Disease Epidemiology Collaboration formula.
!
Stable daily dose(s) within 90 days prior to the day of screening of any of the following 
treatment regimens:
–
1-2 of the following oral anti-diabetic drugs:
- Metformin ≥ 1500 mg or maximum tolerated dose documented in the subject medical 
record), 
- Sulfonylurea (≥ half of the maximum approved dose according to local label or maximum 
tolerated dose as documented in subject medical record)
–
Basal insulin alone (20% change in total daily dose of insulin glargine, insulin detemir, 
insulin degludec or NPH insulin)
or
–
Metformin (≥ 1500 mg or maximum tolerated dose documented in the subject medical 
record) in combination with basal insulin (20% change in total daily dose of insulin 
glargine, insulin detemir, insulin degludec or NPH insulin)

Background information and rationale for the trial
The trial will be conducted in compliance with this protocol, ICH GCP1 and applicable regulatory 
requirements, and in accordance with the Declaration of Helsinki2.
In this document, the term investigator refers to the individual responsible for the overall conduct of 
the clinical trial at a trial site.
3.1
Background information
3.1.1
Type 2 diabetes mellitus
Type 2 diabetes mellitus (T2DM) is a progressive metabolic disease primarily characterised by 
abnormal glucose metabolism. The pathogenesis is heterogeneous involving environmental, 
lifestyle and genetic factors leading to chronic hyperglycaemia caused by peripheral tissue insulin 
resistance, impaired insulin secretion due to abnormal beta-cell function and abnormal glucose 
metabolism in the liver3.
Optimal glycaemic control is the treatment goal in subjects with T2DM in order to prevent long-
term complications associated with chronic hyperglycaemia4. Despite the availability of several 
anti-diabetic drugs, a significant proportion of subjects with T2DM do not achieve the 
recommended targets for glycaemic control5, 6.
3.1.2
Glucagon-like peptide-1
Glucagon-like peptide-1 (GLP-1) is an incretin hormone with a glucose-dependent stimulatory 
effect on insulin and inhibitory effect on glucagon secretion from the pancreatic islets7, 8. 
Subjects with T2DM have a decreased incretin effect9-12. However, the insulinotropic action of 
GLP-1 and thus, the ability to lower blood glucose levels, is preserved when GLP-1 is administered 
at supraphysiological levels13. In addition, supraphysiological levels of GLP-1 induce reduction in 
body weight14. GLP-1 is a physiological regulator of appetite and food intake and GLP-1 receptors 
are present in several areas of the brain involved in appetite regulation15, 16. 
Physiologically, GLP-1 also has a pronounced inhibitory effect on gastric emptying; however this 
effect seems to diminish upon chronic exposure14-16. These mechanisms of action make glucagon-
like peptide-1 receptor agonists (GLP-1 RAs) an attractive pharmacological treatment for T2DM17-
19.
3.1.3
Oral semaglutide
Semaglutide is a long-acting GLP-1 RA structurally similar to liraglutide (Victoza®), a once-daily 
GLP-1 RA developed by Novo Nordisk and approved worldwide for the treatment of T2DM. 
Compared to human native GLP-1, which has a short half-life, the semaglutide molecule has three

minor but important modifications ensuring protraction of its action: amino acid substitutions at 
position 8 (alanine to alfa-aminoisobutyric acid, a synthetic amino acid) and position 34 (lysine to 
arginine) and acylation of the peptide backbone with a spacer and C-18 fatty di-acid chain to lysine 
in position 2620. The fatty di-acid side chain and the spacer mediate strong binding to albumin, 
thereby reducing renal clearance. The amino acid substitution at position 8 makes semaglutide less 
susceptible to degradation by dipeptidyl peptidase-4 (DPP-4). The change in position 34 from a 
lysine to an arginine is included to have only one lysine in the sequence whereto a spacer can be 
attached.
Semaglutide is in development for oral once-daily treatment of T2DM. As the bioavailability of 
GLP-1 RAs is low when administered orally, semaglutide has been co-formulated with the 
absorption-enhancing excipient sodium N-[8-(2-hydroxybenzoyl) amino]caprylate (SNAC) to 
increase the bioavailability of semaglutide. The absorption-enhancing properties of SNAC co-
formulation is based on the 
 concept developed by 
SNAC facilitates the absorption of semaglutide in a strictly time- and size-dependent manner, 
primarily via the transcellular route. The available data for semaglutide co-formulated with SNAC 
support that the absorption takes place in the stomach in a localised, buffered environment in close 
proximity of the tablet erosion. The absorption process is hampered if dosed with food, liquid or in 
the presence of significant stomach content. 
The absorption enhancement requires co-formulation between semaglutide and SNAC. Throughout 
this document “oral semaglutide” will refer to the drug product, that is, semaglutide co-formulated 
with 300 mg SNAC.
3.1.4
Nonclinical data
3.1.4.1
Semaglutide
The nonclinical programme for semaglutide was designed according to the ICH M3 guideline21 to 
support the clinical development. The standard nonclinical data package required to support phase 3 
clinical trials has been completed. In addition, 2-year carcinogenicity studies and a pre- and 
postnatal development toxicity study have been completed. Semaglutide was generally well 
tolerated in animals (mice, rats and cynomolgus monkeys). Two potential safety issues have been 
identified and these are detailed below.
Thyroid C-cell tumours in rodents
Treatment-related non-genotoxic proliferative changes in the thyroid C-cells of mice and rats were 
observed in 2-year carcinogenicity studies with semaglutide; thyroid hyperplasia was preceded by 
an increase in serum calcitonin. C-cell changes have not been observed in long-term studies in non-
human primate. The observed pattern of effects in mice and rats and lack of these effects in the non-
human primate and in man suggest that the mechanism by which semaglutide acts on the thyroid C-

cells in rodents is the same as has been demonstrated for other GLP-1 RAs, including liraglutide. 
According to this mechanism, C-cell hyperplasia is mediated by the GLP-1 receptor and is not 
associated with RET (re-arranged during transfection) gene activation and rodents appear to be 
particularly sensitive, whereas humans are not. The relevance for human subjects is currently 
unknown, but considered to be low22.
Embryo−foetal development toxicity
Semaglutide caused embryo-foetal development toxicity in the rat through a GLP-1 receptor 
mediated effect on the inverted yolk sac placenta leading to impaired nutrient supply to the 
developing embryo. Primates do not have an inverted yolk sac placenta which makes this 
mechanism unlikely to be of relevance to humans and cynomolgus monkeys. In the developmental 
toxicity studies in cynomolgus monkey, a marked maternal body weight loss associated with the 
pharmacological effect of semaglutide coincided with increased early foetal loss; however, there 
was no indication of a teratogenic potential of semaglutide in this species.
A review of the results from the nonclinical studies can be found in the Investigator’s Brochure for 
subcutaneous (s.c.) administration of semaglutide (NN9535), edition 1023 and the Investigator’s
Brochure for oral administration of semaglutide (NN9924), edition 624, or any updates of these
documents.
3.1.4.2
SNAC
SNAC was developed as an absorption-enhancing excipient for the oral route of administration. The 
nonclinical programme to support clinical phase 3 development and marketing authorisation 
application submission has been conducted including a 26-week carcinogenicity study in transgenic 
rasH2 mice and a 2-year carcinogenicity study in Sprague-Dawley rats.

The carcinogenicity studies demonstrated that SNAC was not carcinogenic to the transgenic rasH2 
mouse or the Sprague-Dawley rat. The doses tested covered total exposures of SNAC in plasma (in 
terms of area under the curve [AUC]) of 2-fold in the mouse and up to 44-fold in the rat when 
compared to the mean total exposure of SNAC in humans following a clinical dose of 300 mg 
SNAC/day.
A review of the SNAC results from the nonclinical studies can be found in the Investigator’s 
Brochure for oral administration of semaglutide (NN9924), edition 624, or any updates hereof.
3.1.5
Clinical data for oral semaglutide
A comprehensive clinical pharmacology programme including 12 trials has been completed, as well 
as a 26-week phase 2 dose-finding trial involving more than 600 subjects with T2DM.
For details on the individual trials, please see the Investigator’s Brochure for oral administration of 
semaglutide (NN9924) edition 624, or any updates hereof.
3.1.5.1
Pharmacokinetics
In the multiple-dose trial (NN9924-3991), oral semaglutide has demonstrated a long mean terminal 
half-life (t½) ranging from 153 to 161 hours (~1 week) and a median time to reach maximum 
observed concentration (tmax) ranging from 1 to 2 hours in healthy subjects. 
In multiple-dose pharmacokinetics (PK) trials, the exposure to oral semaglutide increased with 
increasing dose. Overall, the pharmacokinetic properties of semaglutide appeared similar in healthy 
subjects and in subjects with T2DM.
Exposure of semaglutide exhibits a substantially greater dose-to-dose variation following oral 
administration compared to s.c. administration. However, when administered orally once-daily the
PK properties of semaglutide, i.e. low clearance and long half-life, will limit the variation in 
exposure at steady state.
Data obtained following investigation of different dosing conditions for oral semaglutide have 
demonstrated that subjects should take the oral semaglutide tablet in the morning in a fasting state 
and at least 30 minutes before the first meal of the day. 
Drug-drug interaction investigations have explored the effect of oral semaglutide on the exposure to 
lisinopril, warfarin, metformin and digoxin as well as the effect of omeprazole on oral semaglutide 
and SNAC. It was demonstrated that oral semaglutide did not change the exposure to lisinopril, 
warfarin or digoxin, but increased the exposure to metformin when taken simultaneously. The 
increase in exposure to metformin may be related to delayed gastric emptying caused by 
semaglutide as observed for other GLP-1 RAs. Further, it was demonstrated that the exposure to

semaglutide appeared to be slightly higher when administered with omeprazole in comparison to 
semaglutide alone, but the effect was not statistically significant or considered clinically relevant.
In subjects with mild to end-stage renal impairment, the exposure to semaglutide appeared similar 
in subjects with normal and impaired renal function, whereas the exposure to SNAC was greater in 
subjects with impaired renal function than in subjects with normal renal function. The maximum 
concentration (Cmax) of SNAC appeared similar in subjects with normal and impaired renal 
function. The renal clearance of all SNAC metabolites was decreased in subjects with renal 
impairment.
In subjects with mild to severe hepatic impairment, the exposure to semaglutide appeared to be 
unaffected by the degree of hepatic impairment, whereas the exposure to SNAC (in terms of both 
AUC and Cmax) was increased for subjects with hepatic impairment as compared to subjects with 
normal hepatic function.
All tablets of oral semaglutide contain 300 mg of SNAC regardless of the semaglutide dose. SNAC 
is rapidly absorbed with a median tmax ranging from 0.35−0.5 hours in healthy subjects and from 
0.52−1.43 hours in subjects with T2DM. It is extensively metabolised and no accumulation of 
SNAC has been observed in clinical trials.
3.1.5.2
Efficacy
The efficacy of oral semaglutide in adult subjects with T2DM was investigated in a 26-week phase 
2 dose-finding trial (NN9924-3790). In this trial, placebo or one of the following doses of oral 
semaglutide were administered once-daily: 2.5, 5, 10, 20 and 40 mg.
Results from the trial showed that oral semaglutide effectively lowered glycosylated haemoglobin 
(HbA1c) and body weight. Placebo-adjusted reductions in HbA1c were dose-dependent and
statistically significant for all oral semaglutide treatment arms at week 26 (range: -0.40% to -
1.59%). Placebo-adjusted reductions in body weight were dose-dependent and statistically 
significant for oral semaglutide treatment doses of 10 mg and above at week 26 (range: -3.61 kg 
to -6.98 kg).
3.1.5.3
Safety
In the clinical trials completed so far, no unexpected safety findings have been identified for oral 
semaglutide administered up to 40 mg once daily. Consistent with other GLP-1 RAs, commonly 
reported AEs included nausea and vomiting, most of them were mild to moderate in severity. In line 
with findings for other GLP-1 RAs, an increase in heart rate and serum levels of lipase and amylase 
has also been observed in subjects exposed to oral semaglutide.

In addition to the 13 completed clinical trials with oral semaglutide, SNAC has been investigated in 
the programme of orally administrated heparin in combination with SNAC (heparin/SNAC). The 
heparin/SNAC programme (
.) included 29 phase 1 trials (SNAC doses 
ranged from 0.172-10.5 g). In three of these trials, SNAC alone was investigated (to a maximum 
dose of 10.5 g). The trials covered formulation development, food effect, hepatic and renal 
impairment, age-effect and drug-drug interaction. The programme also included a total of three 
phase 2 and 3 trials in which the effects of orally delivered heparin solution (with >1.5 g SNAC 
three times a day) was investigated. The overall safety profile of oral semaglutide and 
heparin/SNAC indicates that SNAC is safe and well-tolerated.

(NN9924) edition 624, or any updates hereof.

3.2
Rationale for the trial
Many patients with T2DM are not in glycaemic control with the currently marketed oral anti-
diabetic drugs. Nevertheless, treatment with more efficacious injectable therapies such as GLP-1 
RAs and insulin are rarely added during the early stages of the disease. Oral semaglutide is the first 
GLP-1 RA in development in a tablet formulation and it has the potential of becoming a new 
attractive treatment option early in the treatment cascade due to its effects on both hyperglycaemia 
and body weight.
Considering that T2DM is often associated with renal impairment, anti-diabetic treatment options 
for this group of patients are limited. Chronic renal impairment is a slowly progressing condition 
and has multiple causes. The most common cause of chronic kidney disease (CKD) is diabetes 
mellitus and is found in about 40% of all patients with T2DM, and the second most common cause 
is hypertension.25, 26
A useful and recommended estimate of renal function can be obtained by estimated glomerular 
filtration rate (eGFR) and it can be categorised based on the Chronic Kidney Disease Epidemiology 
Collaboration (CKD-EPI) equation27. A normal glomerular filtration rate (GFR) varies according to 
many factors, including sex, age, body size and race. A number of formulas to estimate GFR on the 
basis of serum creatinine levels and the above factors have been developed. CKD is divided into 
five stages using a patient’s GFR28. Stage 1 is characterised by kidney damage with normal or 
increased GFR (≥ 90 mL/min/1.73 m2). Stage 2 is characterised by mild reduction in GFR 
(60-89 mL/min/1.73 m2) and stage 3 is characterised by moderate reduction in GFR 
(30-59 mL/min/1.73 m2). Guidelines distinguish between stage 3A (45-59 mL/min/1.73 m2) and 
stage 3B (30-44 mL/min/1.73 m2)29, 30. Stage 4 is characterised by severe reduction in GFR

(15-29 mL/min/1.73 m2) and stage 5 is characterised by end-stage renal disease (GFR 
< 15 mL/min/1.73 m2, or permanent renal replacement therapy).
In many countries metformin is contraindicated in patients with moderate, severe or end-stage renal 
impairment due to concerns of increased risk of lactic acidosis, despite current data indicate that the 
overall risk of lactic acidosis associated with metformin is low. Most treatment guidelines propose 
that metformin should be used with caution at eGFR below 45 mL/min/1.73 m2 and discontinued 
when eGFR is below 30 mL/min/1.73 m2 or in clinical situations in which there is an increased risk 
of lactic acidosis31, 32. Sodium-glucose co-transporter-2 (SGLT-2)-inhibitors have compromised 
efficacy and restricted use, and dose reductions are required for all DPP-4 inhibitors except for 
linagliptin in subjects with renal impairment. Sulfonylurea (SU) may have an increased risk of 
hypoglycaemia in case of renal impairment and thiazolidinediones can cause fluid retention, which 
implies that these drugs should be used with caution in this population31, 32. Therefore, there is a 
need for additional treatment options and to establish the efficacy and safety of novel anti-diabetic 
treatments such as oral semaglutide in patients with T2DM and moderate renal impairment.
The purpose of this 26-week phase 3a trial is to establish efficacy and safety data of the highest 
dose (14 mg) of oral semaglutide versus placebo as add on to metformin and/or SU, basal insulin 
alone or metformin in combination with basal insulin in subjects with T2DM and moderate renal 
impairment. The safety and efficacy of oral semaglutide in subjects with mild renal impairment will 
be established based on data from other PIONEER trials.

Trial design
5.1
Type of trial
This is a 26-week, randomised, double-blind, placebo-controlled, parallel-group, multicentre,
multinational trial with 2 arms comparing the efficacy and safety of oral semaglutide with placebo 
in subjects with T2DM and moderate renal impairment.
Subjects inadequately controlled on metformin and/or SU, basal insulin alone or metformin in 
combination with basal insulin will be randomised 1:1 to receive one of the following treatments:
!
14 mg oral semaglutide once-daily
!
placebo once-daily
as add-on to their background medication.
Randomisation will be stratified according to renal function and antidiabetic background 
medication at screening (see Section 11) to ensure an even distribution of the two treatment arms 
within each stratum.
To maintain the blinding of the trial, all tablets containing oral semaglutide or placebo will be
identical with regards to visual appearance.
The total trial duration for the individual subject will be approximately 33 weeks. The trial includes 
a 2-week screening period, followed by a 26-week randomised treatment period and a follow-up 
period of 5 weeks.
The trial design is illustrated in Figure 5–1.

5.2
Rationale for trial design
The trial has been designed as a parallel-group, 2-armed trial to ensure a direct comparison between
oral semaglutide and placebo. The placebo arm has been chosen to ensure assay sensitivity by 
demonstrating glycaemic effect of oral semaglutide compared to placebo and to establish safety of 
oral semaglutide versus placebo in subjects with T2DM and moderate renal impairment.
Subjects will be randomised between the two treatment arms and the trial will be double-blinded. 
The randomisation will be stratified based on renal function and anti-diabetic background 
medication at screening to ensure an even distribution of the two treatment arms within strata.
The 26-week treatment duration is considered sufficient to ensure adequate time to compare the full 
effect on glycaemic control and body weight after dose escalation of oral semaglutide and 
adjustment of the basal insulin dose in a placebo-controlled trial.
The 5-week follow-up period is included to allow for wash-out of semaglutide and to prevent 
interference in the antibody assay.

fixed 4-week dose escalation intervals. The dose must not be changed during the course of the trial 
once the 14 mg dose of oral semaglutide has been reached.
Placebo treatment
Subjects randomised to placebo will follow the same directions as outlined for the oral semaglutide 
treatment.
5.3.1
Dosing instructions
Oral semaglutide/semaglutide placebo
Absorption of oral semaglutide is significantly affected by food and fluid in the stomach, hence 
dosing should be once-daily in the morning in a fasting state and at least 30 minutes before the first 
meal of the day. The tablets can be taken with up to half a glass of water (approximately 
120 mL/4 fluid oz). The tablets must be swallowed whole by the subject and must not be broken or 
chewed (see Table 9–2). Furthermore, other oral medication can be taken 30 minutes after 
administration of trial product.
5.3.2
Background medication
After signing the informed consent, subjects must continue their anti-diabetic background 
medication (metformin alone, SU alone or in combination with metformin, basal insulin alone or in 
combination with metformin) throughout the entire trial. Metformin and SU must be maintained at 
the same dose level as given at trial entrance and with the same frequency during the entire
treatment period. For subjects on basal insulin (insulin glargine, insulin detemir, insulin degludec or 
NPH insulin) the dose should be reduced at randomisation to minimise the risk of hypoglycaemic
episodes when introducing an additional anti-diabetic agent (see Section 5.3.2.1). However, if a
subject has unacceptable hypoglycaemia on a background medication of SU or basal insulin during 
the trial, the dose of SU or basal insulin can be reduced. Finally, the background medication may be 
adjusted if rescue medication (see Section 6.4) is needed or a safety concern related to the 
background medication arises. If a subject experience persistent decline in renal function (eGFR 
available at randomisation, week 4, 8, 14, 26 and at the follow-up visit) on a background medication 
of metformin the treatment with metformin should be adjusted/discontinued according to the current 
approved local label or guideline due to the risk of lactic acidosis.
In addition, all background medication:

5.3.2.1
Basal insulin dose adjustment
Subjects on basal insulin should have the total daily insulin dose reduced by 20% at randomisation. 
Further reductions may be needed during the trial and in particular during escalation of oral 
semaglutide. After having reached the maximum dose of oral semaglutide (14 mg), basal insulin 
can be up-titrated by the investigator from week 10 to week 16 (P6 to P11) based on the lowest of 
three fasting (for at least 6 hours) pre-breakfast self-measured plasma glucose (SMPGs) values; 
preferably measured on three consecutive days prior to each phone contact/site visit (please see 
Table 5–2). However, the basal insulin dose should not be increased above the dose taken prior 
to randomisation. Increasing the basal insulin dose before week 10 should be avoided, unless 
required to control acute hyperglycaemia or to prevent acute diabetic complications (see Section 6.4
for further details).
In case of hypoglycaemia please see Table 5–3 for guidance on basal insulin dose reduction.
The basal insulin dose should otherwise remain stable during the trial.

product, GLP-1 RAs are not allowed before completion of the follow-up visit 5 weeks after the last 
date on trial product (to avoid interference with the antibody assay for oral semaglutide).
Throughout the protocol, last date on trial product is defined as date of the subject’s last dosage of 
trial product.
As this trial is a phase 3a trial, oral semaglutide will not be available for prescription until after 
marketing authorisation.
5.5
Rationale for treatment
For phase 3 development of oral semaglutide, the three dose levels (3, 7 and 14 mg), treatment 
initiation with the lowest dose and the 4-week dose escalation steps have been chosen based on data 
from the phase 2 dose-finding trial. This regimen is expected to have the optimal benefit-risk profile 
for further development for treatment of T2DM in the PIONEER programme.
In this trial oral semaglutide will be dose escalated to the highest dose (14 mg) to investigate and 
establish the efficacy and safety of the highest dose of oral semaglutide in subjects with moderate 
renal impairment.
Placebo has been selected as comparator as most other oral anti-diabetic drugs approved for 
treatment of T2DM have restrictions or limitations for use in subjects with impaired renal function, 
and in order to establish the safety and efficacy of oral semaglutide vs placebo.
The duration of randomised treatments is considered adequate to collect sufficient data on efficacy 
and safety in accordance with the trial objectives.

photography or dilated fundoscopy performed within 90 days prior to randomisation.
18. History or presence of malignant neoplasms within the last 5 years (except basal and squamous 
cell skin cancer and carcinoma in situ).
6.4
Rescue criteria
Subjects with persistent and unacceptable hyperglycaemia should be offered treatment 
intensification. To allow time for dose escalation to maximum dose of trial product, dose
adjustment of basal insulin, and to observe the expected effect of treatment on glycaemic 
parameters, rescue criteria will be applied from week 12 and onwards. If any of the FPG values 
(including fasting SMPG) exceed the limits outlined below and no intercurrent cause of the 
hyperglycaemia can be identified, a confirmatory FPG value (at the central laboratory) should be 
obtained by calling the subject for a re-test. If the confirmatory FPG value also exceeds the value 
described below, the subject should be offered rescue medication (i.e. intensification of anti-
diabetic background medication and/or initiation of new anti-diabetic medication):
!
13.3 mmol/L (240 mg/dL) from week 12 to end of week 16
!
11.1 mmol/L (200 mg/dL) from week 17 to end of treatment
It is important for trial integrity that only subjects actually needing treatment intensification (as 
defined above) are started on rescue medication. Subjects that are started on rescue medication 
should continue to follow the protocol-specified visit schedule. Rescue medication should be 
prescribed at the investigator’s discretion as add-on to randomised treatment and according to 
ADA/European Association for the Study of Diabetes guidelines31, 32 (excluding GLP-RAs, 
DPP-4 inhibitors and amylin analogues). For subjects with basal insulin as part of their background 
medication, increase of basal insulin dose should be first choice.
Rescue medication and any changes hereto should be captured on the concomitant medication form 
in the electronic case report form (eCRF), see Section 8.2.4. Rescue medication is considered to be
non-investigational medicinal product and will not be provided by Novo Nordisk.

6.5
Criteria for premature discontinuation of trial product 
All efforts should be made to keep the subject on trial product. However, the subject may be 
prematurely discontinued from trial product at the discretion of the investigator due to a safety 
concern.
The subject must be prematurely discontinued from trial product if the following applies:
1. Safety concern related to trial product or unacceptable intolerability
2. Included in the trial in violation of the inclusion and/or exclusion criteria
3. Pregnancy
4. Intention of becoming pregnant
5. Simultaneous participation in another clinical trial of an approved or non-approved 
investigational medicinal product
6. Calcitonin ≥ 100 ng/L
If a criterion for premature discontinuation of trial product is met, trial product should not be re-
initiated but subjects should continue with the scheduled site contacts.
See Section 8.1.5 for procedures to be performed for subjects discontinuing trial product 
prematurely.
6.6
Withdrawal from trial
The subject may withdraw consent at will at any time. The subject’s request to withdraw from the 
trial must always be respected. Only subjects who withdraw consent should be considered as 
withdrawn from trial.
See Section 8.1.6 for procedures to be performed for subjects withdrawing consent.
6.7
Subject replacement
Subjects who withdraw consent or discontinue trial product prematurely will not be replaced.
6.8
Rationale for trial population 
The trial population will include subjects with T2DM and moderate renal impairment treated with 
stable doses of metformin and/or SU, basal insulin alone or metformin in combination with basal 
insulin for at least 90 days prior to screening as changes in the background medication shortly 
before trial participation may potentially impact the data interpretation. The HbA1c limits of 
7.0-9.5% (53-80 mmol/mol) have been chosen to include subjects needing intensification of their 
anti-diabetic treatment. The upper limit will ensure that subjects with severely dysregulated T2DM 
are not enrolled in this placebo-controlled trial. In addition, FPG and HbA1c will be monitored
throughout the trial and rescue medication should be initiated in subjects with persistent, 
unacceptable hyperglycaemia. Subjects with moderate renal impairment (eGFR of

or blood pressure restrictions will be applied. Subjects with liver test abnormalities (ALT > 2.5 x 
UNL) will be excluded to avoid potential confounding of liver safety assessments. Subjects with 
hypoglycaemia unawareness will be excluded due to the increased risk of hypoglycaemia for 
subjects with moderate renal impairment treated with SU or basal insulin. Overall, the eligibility 
criteria will allow for enrolment of a relatively broad trial population resembling the target 
population in common practice.

Methods and assessments
8.1
Visit procedures
The following sections describe the assessments and procedures. These are also included in the flow 
chart (see Section 2). Informed consent must be obtained before any trial related activity, see 
Section 18.2.
Refer to flowchart (Section 2) for number and timing of visits and specific assessments to be 
performed.
Each subject will attend 8 site visits and 1 phone contact. Subjects taking basal insulin as 
background medication will have to attend 5 additional phone contacts (P6, P7, P8, P9 and P11) 
during the treatment period to adjust their basal insulin (see Section 5.3.2.1). It is the responsibility 
of the investigator to ensure that all visits/contacts occur according to the flow chart (see Section 2).
Planned visits can be conducted and re-scheduled within the allowed visit window. If a visit is 
missed and it is not possible to re-schedule, every effort should be made to ensure information is 
collected at a phone contact (within the visit window) and entered into the eCRF. Subjects will be 
invited for the next scheduled visit according to the visit schedule.
The investigator must keep a log of staff and a delegation of task(s) list at site. Investigator must 
sign the log of staff and the delegation of task(s) at site prior to the delegation of tasks.
The investigator must keep a subject screening log, a subject identification code list and a subject 
enrolment log. Only subjects who have signed the informed consent form should be included on the 
logs. The subject screening log and subject enrolment log may be combined in one log.
8.1.1
Screening, visit 1
At screening, subjects will be provided with a card stating that they are participating in a trial and 
giving contact address(es) and telephone number(s) of relevant trial site staff. Subjects should be 
instructed to return the card to the investigator at the last trial visit or to destroy the card after the 
last visit.
A screening session must be made in the IWRS. Each subject will be assigned a unique 6-digit 
subject number which will remain the same throughout the trial.
Once all data relating to V1 have been obtained, these must be reviewed, dated and signed by the 
investigator and/or documented in medical records to assess that the subject is eligible to continue 
in the trial.

Screening failures: For screening failures the screening failure form in the eCRF must be 
completed with the reason for not continuing in the trial. Serious adverse events (SAEs) from 
screening failures must be transcribed by the investigator into the eCRF. Follow-up on SAEs must 
be carried out according to Section 12.
A screening failure session must be made in the IWRS. The case book must be signed.
Re-screening is NOT allowed if the subject has failed one of the inclusion or exclusion criteria; this 
includes re-sampling if the subject has failed one of the inclusion or exclusion criteria related to 
laboratory parameters. However, in case laboratory samples are lost (e.g. haemolysed or displaced),
re-sampling is allowed.
8.1.2
Fasting visits
The subjects must attend several visits in a fasting state (see Section 2).
Fasting for blood sampling is defined as no food or liquid within the last 8 hours prior to blood 
sampling, however water is allowed up until 2 hours prior to blood sampling.
Trial product must be taken after blood sampling (see Section 5.3.1 for dosing instructions). Other 
oral medication can be taken 30 minutes after trial product. Injectable medications can be 
administered after blood sampling. Note that for all subjects, the required fasting period is longer at 
visits with PK sampling (see Section 8.6.1).
In case a subject attends a fasting visit in a non-fasting state, all non-fasting measurements should 
be performed. The subject should return to the site in a fasting state to have the fasting blood 
samples done within the visit window for the relevant visit.
Fasting samples:
!
FPG
!
fasting lipid profile (total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides)
!
SNAC PK
!
semaglutide PK
8.1.3
Randomisation and trial product administration
Eligible subjects will be randomised into one of two treatment arms. The randomisation session 
must be performed in the IWRS which will allocate the dispensing unit number (DUN) of trial 
product to be dispensed to the subject.
All V2 assessments must be performed before administration of first dose of trial product.

Trial product (see Section 9) will be dispensed to the subject by the site, hospital pharmacy or 
equivalent at each site visit during the trial from randomisation to last visit before the end-of-
treatment visit (see Section 2). The investigator must document that subjects are trained in the 
dosing instructions at every dispensing visit, please see Section 5.3.1.
Date of first administration of trial product will be captured in the eCRF.
8.1.4
End-of-treatment (visit 13) and Follow-up (visit 14)
Subjects, who stay on trial product throughout the trial, must attend the end-of-treatment visit (V13) 
26 weeks after randomisation and the follow-up visit (V14) 5 weeks after the last date on trial 
product (+3 days visit window). A completion call must be performed in the IWRS after completion 
of V13 (see Section 10).
In case the subject cannot be reached (by clinic visit or phone contact) at the scheduled V14, the site 
should consult the contacts provided by the subject (e.g. close relatives), relevant physicians, 
medical records and locator agencies (if allowed according to local law) to collect health status. If 
no health status can be collected, the subject should be considered lost to follow-up and this should 
be specified in the end-of-trial form.
8.1.5
Premature discontinuation of trial product and follow-up (visit 13A and visit 14A)
Subjects, who discontinue trial product prematurely, should attend V13A scheduled to take place on 
the day of discontinuation of trial product (+3 days visit window). V14A should be scheduled 5 
weeks (+3 days visit window) after the last date on trial product. The primary reason for premature 
discontinuation of trial product must be specified in the end-of-trial form in the eCRF, and final 
drug accountability must be performed. A treatment discontinuation session must be made in the 
IWRS at V13A (see Section 10).
If premature discontinuation of trial product is decided during a scheduled visit, the visit will be 
converted into a V13A and trial procedures must be performed accordingly.
Subjects should continue with the originally scheduled site contacts after V14A and up to and 
including V13. If necessary, in order to retain the subject in the trial, site visits can be replaced by 
phone contacts after V14A. However, if a subject is unable or unwilling to attend all subsequent 
visit(s), the investigator should at least aim to have the subject attend V13 (end-of-treatment) as this 
visit should be performed for all subjects, if at all possible (except subjects who withdraw informed 
consent, see Section 8.1.6).
Subjects, who only agree to attend or provide health status at the planned V13, should not be 
considered withdrawn from the trial. In case the subject cannot be reached (by clinic visit or phone 
contact) at the scheduled V13, the site should consult the contacts provided by the subject (e.g. 
close relatives), relevant physicians, medical records and locator agencies (if allowed according to

local law) to collect health status. If no health status can be collected, the subject should be 
considered lost to follow-up and this should be specified in the end-of-trial form.
In summary, subjects should stay in the trial irrespective of lack of adherence to randomised 
treatment, lack of adherence to visit schedule, missing assessments or trial product discontinuation 
for any reason. Only subjects who decline any further contact with the site in relation to the trial 
should be considered as withdrawn from the trial (for withdrawal procedures see Section 8.1.6).
8.1.6
Withdrawal from trial
If a subject considers withdrawing from the trial, the investigator must aim to undertake procedures 
for V13A as soon as possible and V14A should be scheduled 5 weeks (+3 days visit window) after 
the last date on trial product, if the subject agrees to it.
The end-of-trial form must be completed, and final drug accountability must be performed even if 
the subject is not able to come to the trial site. A treatment discontinuation session must be made in 
the IWRS (see Section 10). The case book must be signed.
Although a subject is not obliged to give his/her reason(s) for withdrawing consent, 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 withdrawing consent must be specified in 
the end-of-trial form in the eCRF.
8.1.7
Investigator assessments
Review of diaries, PROs, laboratory reports, ECGs and fundus photography/dilated fundoscopy
must be documented either on the documents or in the subject’s medical record.
If clarification of entries or discrepancies in the diary or PROs is needed, the subject must be 
questioned and a conclusion made in the subject’s medical record. Care must be taken not to bias 
the subject.
The documents must be retained at the site as source documentation.
For ECGs, physical examinations and eye examinations, the evaluations must follow the categories:
!
Normal
!
Abnormal
–
Was the result clinically significant? (yes/no)
The evaluation should be based on investigator’s judgement.
For laboratory report values outside the reference range, the investigator must specify whether the 
value is clinically significant or not clinically significant. All laboratory printouts must be signed

The blood glucose meters use test strips calibrated to plasma values. Therefore, all measurements 
performed with capillary blood are automatically calibrated to plasma equivalent glucose values, 
which will be shown on the display.
Only the blood glucose meter provided by Novo Nordisk should be used for the measurements 
required in the protocol.
All subjects should use the provided blood glucose meter for SMPG measurements in relation to 
hypoglycaemic episodes. For subjects with basal insulin as background medication fasting SMPG 
values should also be measured prior to insulin adjustment as outlined in Section 5.3.2.1 and 
Section 8.3.2.1.

Subjects should be instructed in how to record the results of the SMPG values in the diaries. The 
record of each SMPG value should include date, time and value. All data from the diary must be 
transcribed into the eCRF during or following the contact. If obtained via phone and a discrepancy 
is later detected between the diary and the SMPG data obtained at the phone contact, the values in 
the eCRF must be corrected.
Occasional review by the investigator of the values stored in the memory of the blood glucose meter 
and correct reporting of these in the diary is advised in order to ensure adequacy of the data reported 
in the trial database.
8.3.2.1
Basal insulin dose adjustment
For subjects on basal insulin as background medication the investigator should at V2 record the 
subject’s total daily dose of basal insulin prior to the visit and after dose reduction in the eCRF.
The investigator should from week 10 to week 16 (P6 to P11) review the subject’s basal insulin 
dose as specified in Section 2 and Section 5.3.2. Results of the subject’s SMPG measurements and 
total daily dose of basal insulin prior to each contact will be transcribed into the eCRF and based on 
these, dose adjustment guidance will be provided. Reason for deviation from dose adjustment 
guidance will be recorded in the eCRF. All adjustments of basal insulin dose level will be captured 
in the eCRF. From V12 and until follow-up the investigator should record the subject’s total daily 
dose of basal insulin prior to each visit in the eCRF.
8.3.3
Body weight and height
Body weight must be measured and recorded in the eCRF in kilogram or pound (kg or lb), with one 
decimal (with an empty bladder, without shoes and only wearing light clothing). The body weight 
should be assessed on the same calibrated weighing scale equipment throughout the trial, if 
possible.
Height is measured without shoes in centimetres or inches and recorded in the eCRF to nearest 
½ cm or ¼ inch.
8.3.4
Waist circumference
The waist circumference is defined as the minimal abdominal circumference located midway 
between the lower rib margin and the iliac crest.
The measurement of waist circumference must be performed and recorded in the eCRF. Waist 
circumference is measured in the horizontal plane and rounded up or down to the nearest ½ cm or 
¼ inches using a non-stretchable measuring tape. The same measuring tape should be used 
throughout the trial.

The circumference should be measured when the subject is in a standing position, with an empty 
bladder and wearing light clothing. The subject should be standing, feet together with arms down 
their side and waist accessible. 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 and the 
measurement should be taken when the subject is breathing out gently.

Patient reported outcomes questionnaires
PROs will be assessed using the questionnaires:
!
Short Form (SF)-36v2™(acute version) health survey38-40
!
Diabetes Treatment Satisfaction Questionnaire – status version (DTSQs)41
The questionnaires must be completed by the subject as specified in the flow chart, see Section 2, 
preferably before any other trial-related activities for that visit. It takes approximately ten minutes 
to complete the two questionnaires. Subjects should be given the opportunity to complete the 
questionnaires by themselves without interruption. The completed questionnaires must be reviewed 
for potential AEs and missing data while the subject is still at the site. All results from the PRO 
questionnaires must be transferred into the eCRF.
All the questionnaires will be translated to local languages, and also be linguistically validated 
before being handed out to the subjects participating in the trial. 
Short Form (SF)-36v2TM (acute version) health survey
The Short Form (SF)-36v2™(acute version) health survey measures the individual overall health 
related quality of life on 8 domains; Physical functioning, Role physical, Bodily pain, General 
health, Vitality, Social functioning, Role emotional and Mental health. The acute version’s 
questions are based on a recall period of one week. The Short Form (SF)-36v2™(acute version) 
health survey contains 36 items.
Diabetes Treatment Satisfaction Questionnaire – status version
The Diabetes Treatment Satisfaction Questionnaire – status version (DTSQs) questionnaire will be 
used to assess subject’s treatment satisfaction. This questionnaire contains 8 items that measures the 
treatment satisfaction for subjects’ diabetes treatment in terms of convenience, flexibility and 
general feelings regarding treatment.

8.4.5
Electrocardiogram (12-lead)
12-lead ECG will be performed as per flow chart (see Section 2) and the assessment must be 
reviewed as described in Section 8.1.7 by the investigator. The ECGs will also undergo central 
assessment and the investigator must forward the ECGs to the central ECG reader as soon as 
possible.
If the central ECG evaluation of a baseline ECG is suggestive of a prior myocardial infarction, the 
investigator will be notified. The investigator should consider if an update of the History of 
cardiovascular disease form is required.
If the central ECG evaluation of a post-baseline ECG is suggestive of new myocardial infarction, 
the investigator will be notified and a confirmatory ECG should be performed. Unless already done, 
the investigator should report this as an AE or a SAE at investigator’s discretion and according to 
Section 12. 
Additional ECG recordings can be performed at the investigator’s site at investigator’s discretion at 
other visits than the planned ECG visits. All these ECGs will undergo central assessment. The 
reason for additional ECG assessments should be documented and an AE should be reported if 
applicable.
All findings suggestive of new myocardial infarction detected by the central ECG reading will be 
adjudicated by the event adjudication committee (EAC) (see Section 12.7.2).

antibodies will be further characterised for in vitro neutralising effect towards semaglutide. In 
addition, samples which are positive for antibodies cross-reacting with native GLP-1 will be further 
analysed for in vitro neutralising effect towards native GLP-1.
Furthermore, samples drawn at randomisation may be used for calculations of the neutralising effect 
in the in vitro neutralising antibody assays. The in vitro neutralising assays will be performed by 
Novo Nordisk.
At randomisation, the antibody sampling must be done pre-dose.

All plasma glucose values:
!
≤ 3.9 mmol/L (70 mg/dL) or 
!
> 3.9 mmol/L (70 mg/dL) occurring in conjunction with hypoglycaemic symptoms
should be reported in the diary according to the instructions below throughout the trial from V1 to 
end of trial.
Upon onset of a hypoglycaemic episode the subject is recommended to measure plasma glucose
every 15 minutes until the SMPG value is > 3.9 mmol/L (70 mg/dL) and/or symptoms have been 
resolved in accordance to current guidelines43.
A SMPG value ≤ 3.9 mmol/L (70 mg/dL) or hypoglycaemic symptoms must trigger a 
hypoglycaemic episode form to be completed by the subject. Repeated SMPG measurements and/or 
symptoms will per default be considered as one hypoglycaemic episode until a succeeding SMPG 
value is > 3.9 mmol/L (70 mg/dL) and/or symptoms have been resolved. One hypoglycaemic 
episode form is to cover these measurements and/or symptoms.
In case of several low SMPG values within the hypoglycaemic episode, the lowest value is the one 
that will be reported as the SMPG value for the hypoglycaemic episode but the start time of the 
episode will remain as the time for the first SMPG value and/or symptom.
The record should include the following information: 
!
Start date and time of the hypoglycaemic episode.
!
Stop date and time of the hypoglycaemic episode (stop time is the first time the plasma glucose 
value is > 3.9 mmol/L (70 mg/dL) and/or symptoms have been resolved).
If a stop date and time is not reported, a hypoglycaemic episode will cover a period of 60 
minutes.
!
The plasma glucose level before treating the episode (if available) and any follow up 
measurements. 
The lowest value measured during the hypoglycaemic episode will be reported as the plasma 
glucose value for the episode, the remaining values will be kept as source data in the diary.
!
Whether the episode was symptomatic (Yes/No).
A hypoglycaemic episode starting without symptoms should be updated to symptomatic if the 
subject experiences symptoms later during the episode.
!
Whether the subject was able to treat him/herself.
If the severity of a hypoglycaemic episode aggravates, only one hypoglycaemic episode should 
be reported reflecting the most severe degree of hypoglycaemia.
!
Date and time of last trial product administration, and for selected anti-diabetic medications 
administered prior to the episode, date and time as well as dose must be collected.
!
Date and time of last main meal (not including snacks) prior to the episode.

The answer to the question: "Was the subject able to treat him/herself?" must be answered "No" for 
an episode requiring assistance of another person to actively administer carbohydrate, glucagon, or 
take other corrective actions. Plasma glucose concentrations may not be available during an event, 
but neurological recovery following the return of plasma glucose to normal is considered sufficient 
evidence that the event was induced by a low plasma glucose concentration43.
Oral carbohydrates must not be given if the subject is unconscious.
If the question "Was the subject able to treat him/herself?" is answered "No", the following 
information should be recorded by the subject:
!
Who assisted in the treatment of the hypoglycaemic episode (i.e. medical person or non-medical 
person)?
!
Where the treatment was administered (in clinic/emergency room/hospital or other. If the 
subject was treated in clinic/emergency room/hospital, whether they were transported in an 
ambulance or not)
!
Type of treatment provided by another person (i.e. oral carbohydrates, glucagon, IV glucose or 
other)
!
Were symptoms alleviated after administration of treatment?
!
Factors contributing to the episode (i.e. physical activity, missed meal, diet change, medication 
error (i.e. overdose, mix-up between products, incorrect use of device), other factors not listed 
or unknown)
!
Did the subject experience seizure?
!
Was the subject unconscious/comatose?
!
Did the subject experience any of the following symptoms44 (layman term used in the diary is 
specified in brackets if different from the protocol term)?
–
Autonomic: sweating, trembling, hunger or palpitations (rapid or irregular heart beat)
–
Neuroglycopenic: confusion, drowsiness, speech difficulty, visual disturbances, odd 
behaviour, impaired balance or incoordination (reduced ability to coordinate movement)
–
General malaise: headache or malaise (feeling discomfort/unease)
!
Other symptoms
The Investigator must review the diary for low SMPG values not reported as hypoglycaemic 
episodes (only applicable for subjects on basal insulin as background medication; see Section 2 for 
relevant visits). The subject must be questioned whether any of the low values were severe, i.e.

whether the subject was able to self-treat or not. If the subject was not able to self-treat, it has to be 
reported as a severe hypoglycaemic episode on a hypoglycaemic episode form.
Low SMPG values for non-severe hypoglycaemic episodes not having a hypoglycaemic episode 
form completed within 7 days since the SMPG measurement should be reported on a 
hypoglycaemic episode form with as much information as possible. Novo Nordisk will not query 
for additional data except for the start date, SMPG value and whether the subject was able to self-
treat due to decreased validity of such data45, 46
The subject must be re-trained in how to report hypoglycaemic episodes if the investigator identifies 
low SMPG values not reported as hypoglycaemic episodes.
If the hypoglycaemic episode fulfils the criteria for an SAE then an AE form and a safety 
information form must also be filled in, see Section 12.

Laboratory assessments
The laboratory analyses will mainly be performed by a central laboratory. Anti-semaglutide 
antibodies, in vitroneutralising effectto semaglutide and GLP-1, IgE anti-semaglutide antibodies 
and PK samples will be analysed by a special laboratory and Novo Nordisk(see Sections 8.4.8and 
Section8.6.1). For some of the analyses related to suspicion of acute pancreatitis and 
hypersensitivity reactions, a local laboratory must be used (see appendix B).
The handling, transportation and storage of biological samples are described in the laboratory 
manual (for central and special laboratory details see Attachment I).
Samples will be coded in order to keep subject identity anonymous.
Laboratory samples not drawn on the day of the actual visit should preferably be drawn on another 
day within the visit window stated in the flow chart (see Section2). Please note that a laboratory 
sample pertaining to a specific visit must always be reported to that visit.
For some of the samples drawn during the trial, subjects will be asked to attend the site visits fasting 
(fasting for blood sampling is defined in Section8.1.2).
The central laboratory will provide laboratory results to the investigator on an on-going basis.
However, anti-semaglutide antibodyresults,semaglutideand SNACplasma concentration results 
will not be available to the investigator during the trial. These results will be provided to the 
investigator upon request after the completion of the clinical trial report.
The laboratory provides results to the trial sites in the units preferred by the trial sites while the 
results that are transferred to the trial database will always be in SI units.

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 and report 
these according to Section 8.2.3 and Section 12.
Laboratory samples will be destroyed no later than at finalisation of the clinical trial report, or 
according to local regulations, except samples obtained for antibody analysis. Antibody samples 
will be stored as described in Section 24.2.

Other assessments
8.6.1
Pharmacokinetics
Blood samples will be drawn for assessment of plasma concentration of semaglutide and SNAC at 
selected visits (see Section 2). The semaglutide concentrations will be used for population PK 
analysis.
Blood samples for PK assessments must be collected, handled and shipped according to the 
description in the laboratory manual supplied by the central laboratory (see Attachment I).
The PK responsible laboratory will be provided with the randomisation list and only samples from 
subjects treated with oral semaglutide will be analysed for semaglutide and SNAC plasma 
concentrations.
Semaglutide PK and SNAC PK samples will be stored at the specialised laboratory until final 
clinical trial report in case Novo Nordisk request further analysis of the PK samples.
8.6.1.1
Semaglutide PK sampling
Samples for semaglutide PK can be drawn at any time during the visit. For simplicity it is 
recommended to take the sample for semaglutide PK together with biochemistry samples at all 
visits requiring semaglutide PK.
The date and exact time of the latest trial product administration prior to semaglutide PK sampling 
must be recorded in the diary and entered into the eCRF. The date and time of sampling must be 
recorded on the laboratory requisition form.

to what was dispensed at the last dispensing visit and, in case of discrepancies, question the subject.
If a subject is found to be non-compliant, the investigator will remind the subject of the importance 
of following the instructions given including taking the trial products as prescribed and should 
document this discussion in the subject’s medical record.

Trial supplies
Trial supplies comprise trial products and auxiliary supplies. Additional details regarding trial 
supplies can be found in the Trial Materials Manual.
Trial products must not be dispensed to any person not included in the trial.
9.1
Trial products
The following trial products are considered as investigational medicinal products and will be 
provided by Novo Nordisk A/S, Denmark:

Metformin, SU, basal insulin (insulin glargine, insulin detemir, insulin degludec or NPH insulin) 
and rescue medication are considered non-investigational medicinal products and will not be 
supplied by Novo Nordisk. However, metformin, SU and basal insulin (insulin glargine, insulin 
detemir, insulin degludec or NPH insulin) will be reimbursed if required by the country’s regulatory 
authority or institutional review board (IRB)/independent ethics committee (IEC).
“For Russia only: Maintaining subjects on the basal insulin subjects were using at trial entry is 
important for the integrity of the trial. Therefore, if governmental supply of the subjects basal 
insulin ceases, leaving subjects without the option to continue on background basal insulin, then 
Novo Nordisk may reimburse the cost of maintaining the subject on the trial entry basal insulin for 
the time the subject is included in the trial, or until supply of the basal insulin is re-instituted, if this 
occurs earlier. Novo Nordisk will only reimburse the basal insulin as long as the subject is included 
in the trial.”
For semaglutide, the active drug tablets and the corresponding placebo tablets are identical with 
regard to visual appearance; and all semaglutide tablets are visually identical to each other, 
irrespective of dose levels.

11 Randomisation procedure and breaking of blinded codes
The trial is a double-blinded trial. A randomisation session will be carried out for all subjects using
the IWRS.
At the randomisation visit (V2) subjects meeting all eligibility criteria will be randomised to one of 
two parallel treatment arms as described in Section 5.1.
Randomisation will be stratified based on two factors; renal function including two levels and 
antidiabetic background medication at screening including 3 levels:
!
Renal function (eGFR 30 - 44 mL/min/1.73 m2 and eGFR 45 - 59 mL/min/1.73 m2 as per CKD-
EPI)
!
Antidiabetic background medication at screening (metformin alone, SU alone or in combination 
with metformin, basal insulin alone or in combination with metformin)
to ensure an even distribution of the two treatment arms within the six strata.
At least 40% of the subjects must be randomised to the low eGFR strata.
Centralised treatment allocation will be applied for this trial.
11.1
Breaking of blinded codes
The IWRS will notify Novo Nordisk (monitor and the Global Safety department) immediately after 
the code is broken.
The code for a particular subject may be broken in a medical emergency if knowing the actual 
treatment would influence the treatment of the subject. Whenever a code is broken the person 
breaking the code must print the Code Break Confirmation Notification generated by the IWRS, 
record the reason, and sign and date the document.
When the code is broken, the treatment allocation will be accessible to the investigator and the 
Novo Nordisk Global Safety department. If IWRS is not accessible at the time of code break the 
IWRS helpdesk should be contacted. Contact details are listed in Attachment I. If the code has been 
broken, the subject must discontinue treatment with trial product but be asked to continue in the 
trial (see Section 8.1.5). A treatment discontinuation session must be completed in IWRS.
The laboratory responsible for antibody and pharmacokinetic analysis and the responsible 
development bioanalysis scientist in Novo Nordisk will have access to the unblinding report in the 
IWRS.

12 Adverse events, technical complaints and pregnancies
12.1
Definitions
12.1.1
Adverse event
An AE is any untoward medical occurrence in a subject administered a medicinal product, and 
which does not necessarily have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory 
finding), symptom or disease temporally associated with the use of a product, whether or not 
considered related to the product.
An AE includes:
!
A clinically significant worsening of a concomitant illness.
!
A CLAE: a clinical laboratory abnormality 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.
The following should not be reported as AEs:
!
Pre-existing conditions, including those found as a result of screening or other trial procedures 
performed before exposure to trial product (pre-existing conditions should be reported as 
medical history or 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.
!
Non-serious hypoglycaemia is an AE, but is reported on a hypoglycaemic episode form instead 
of on an AE form, see Section 8.4.9.
The following three definitions are used when assessing an AE:
!
Severity
–
Mild - no or transient symptoms, no interference with the subject’s daily activities.
–
Moderate - marked symptoms, moderate interference with the subject’s daily activities.
–
Severe - considerable interference with the subject’s daily activities; unacceptable.
!
Causality
Relationship between an AE and the relevant trial product(s): 
–
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.

Final 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 sequela 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 fatal outcome must be reported as an 
SAE.
–
Unknown - This term is only applicable if the subject is lost to follow-up.
12.1.2
Serious adverse event
A serious adverse event (SAE) is an experience that at any dose results in any of the following:
!
Death.
!
A life-threateninga experience.
!
In-patient hospitalisationb or prolongation of existing hospitalisation.
!
A persistent or significant disability or incapacityc.
!
A congenital anomaly or birth defect.
!
Important medical events that may not result in death, be life threateninga or require 
hospitalisationb may be considered an SAE when - based on appropriate medical judgement -
they may jeopardise the subject and may require medical or surgical intervention to prevent one 
of the outcomes listed in the definition of SAEd.
a
The term "life threatening" in the definition of SAE refers to an event in which the subject was 
at risk of death at the time of the event. It does not refer to an event which hypothetically might 
have caused death if it was more severe.
b
The term "hospitalisation" is used when a subject:
–
Is admitted to a hospital or in-patient, irrespective of the duration of physical stay, or 
–
Stays at the hospital for treatment or observation for more than 24 hours

Medical judgement must always be exercised, and when in doubt, the hospital contact should be 
regarded as a hospitalisation. 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.
c
A substantial disruption of a subject’s ability to conduct normal life functions (e.g. following the 
event or clinical investigation the subject has significant, persistent or permanent change, 
impairment, damage or disruption in his/her body function or structure, physical activity and/or 
quality of life).
d
For example intensive treatment in an emergency room or at home of allergic bronchospasm, 
blood dyscrasia or convulsions that do not result in hospitalisation, or development of drug 
dependency or drug abuse.
The following AEs must always be reported as an SAE 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).
Additional assessments should be made for events meeting the criterion of Hy’s law as stated above 
(see appendix B).

12.1.4
Medication errors
A medication error concerning trial products is defined as:
!
Administration of wrong drug.
Note: Use of wrong DUN is not considered a medication error.
!
Wrong route of administration.
!
Administration of an overdose with the intention to cause harm (e.g. suicide attempt), misuse or 
abuse of trial product.
!
Accidental administration of a higher dose than intended. A higher dose is a dose of at least one 
tablet more than the intended dose; 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.
Medication errors must be reported on an AE form and a specific event form, see Section 8.4.1.1, 
Section 12.1.5 and appendix B.
12.1.5
Adverse events requiring additional data collection
AEs requiring additional data collection are AEs where the additional data will benefit the 
evaluation of the product safety. A number of AEs that always require additional data collection 
have been pre-specified. See appendix B for details about these events and the additional 
information to report.
Some events in this trial will be adjudicated by an independent external committee as described in 
Section 12.7.2.
Table 12–1 lists AEs that require completion of specific event forms in the eCRFs and/or are 
subject to event adjudication.

Only technical complaints related to AEs will be reported in the clinical trial report.
12.2
Reporting of adverse events
All events meeting the definition of an AE must be collected and reported. This includes events 
from the first trial-related activity after the subject has signed the informed consent until the end of 
the post-treatment follow-up period (V14) for subjects on trial product or until the end of trial (V13
or V14A, whichever comes last) for the subjects who have discontinued trial product prematurely.
Events for withdrawn subjects will be collected and reported until last trial related contact with the 
subject. The events must be recorded in the applicable eCRF forms in a timely manner, see 
timelines below and Figure 12–1.
During each contact with the trial site staff, the subject must be asked about AEs and technical 
complaints, for example by asking: ”Have you experienced any problems since the last contact?”
All AEs, either observed by the investigator or subject, must be reported by the investigator and 
evaluated.
All AEs must be recorded by the investigator on an AE form. The investigator should report the 
diagnosis, if available. If no diagnosis is available, the investigator should record each sign and 
symptom as individual AEs using separate AE forms.
For SAEs, a safety information form must be completed in addition to the AE form. A safety 
information form is a form to collect supplementary clinical information. If several symptoms or 
diagnoses occur as part of the same clinical picture, one safety information form can be used to 
describe all the SAEs.
AEs requiring additional data collection must be reported using both the AE form and the specific 
event form. A specific event form is a form tailored to collect specific information related to the 
individual event. See appendix B for details about the events and the additional information to 
report.
In case any of these events fulfil the criteria for seriousness in Section 12.1 then the event should be 
reported as serious.

Some events will undergo event adjudication by the EAC, please refer to Section 12.7.2. For AEs 
qualifying for event adjudication, the adjudication form will also have to be completed in the eCRF. 
The adjudication form is a checklist of clinical data to be provided from the site.
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.
Timelines for initial reporting of AEs:
The investigator must complete the following forms in the eCRF within the specified timelines:
!
SAEs: The AE form within 24 hours and the safety information form within 5 calendar days 
of the investigator's first knowledge of the SAE.
Both forms must be signed within 7 calendar days from the date the information was entered in 
the eCRF.
For SAEs requiring reporting on a specific event form: In addition to the above, the specific 
event form within 14 calendar days from the investigator’s first knowledge of the AE.
!
Events for adjudication: The adjudication form should be completed within 14 calendar days 
of the investigator’s first knowledge of the AE, see Section 12.7.2. The investigator should 
preferably provide the medical documentation within 4 weeks of event identification according 
to instructions in the event adjudication site manual.
If the eCRF is unavailable, the concerned AE information must be reported on a paper AE form and 
sent to Novo Nordisk by fax, e-mail or courier within the same timelines as stated above. When the 
eCRF becomes available again, the investigator must enter the information on the form into the 
eCRF.
Contact details (fax, telephone, e-mail and address) are provided in the investigator trial master file.

Reporting of AEs
Novo Nordisk assessment of AE expectedness:
Novo Nordisk assessment of expectedness is performed according to the following reference 
document: Investigator’s Brochure, oral semaglutide (NN9924), edition 624, or any updates hereof.
Reporting of trial product-related SUSARs by Novo Nordisk:
Novo Nordisk will notify the investigator of trial product-related suspected unexpected serious 
adverse reactions (SUSARs) in accordance with local requirements and ICH GCP1. In addition, the 
investigator will be informed of any trial-related SAEs that may warrant a change in any trial 
procedure.
In accordance with regulatory requirements, Novo Nordisk will inform the regulatory authorities, 
including European Medicines Agency, of trial product-related SUSARs. In addition, Novo Nordisk 
will inform the IRBs/IECs of trial product-related SUSARs in accordance with local requirement 
and ICH GCP1, unless locally this is an obligation of the investigator.
Novo Nordisk products used as concomitant medication or non-investigational medicinal 
product:
If an AE is considered to have a causal relationship with a Novo Nordisk marketed product used as 
non-investigational medicinal product or 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.
12.3
Follow-up of adverse events
The investigator must record follow-up information by updating the medical records and the forms 
in the eCRF.
Follow up information must be reported to Novo Nordisk according to the following:
!
SAEs: All SAEs must be followed until the outcome of the event is “recovered/resolved”, 
“recovered/resolved with sequelae” or “fatal”, and until all queries have been resolved. Cases of 
chronic conditions, cancer or AEs ongoing at time of death (where death is due to another AE) 
may be closed with the outcome “recovering/resolving” or “not recovered/not resolved”. Cases 
can be closed with the outcome of “recovering/resolving” when the subject has completed the 
follow-up period and is expected by the investigator to recover.
The SAE follow-up information should only include new (e.g. corrections or additional) 
information and must be reported within 24 hours of the investigator’s first knowledge of the 
information. This is also the case for previously non-serious AEs which subsequently become 
SAEs.
!
Non-serious AEs: Non-serious AEs must be followed until the outcome of the event is 
“recovering/resolving”, “recovered/resolved” or “recovered/resolved with sequelae” or until the 
end of the follow-up period stated in the protocol, whichever comes first, and until all queries 
related to these AEs have been resolved. Cases of chronic conditions, cancer or AEs ongoing at 
time of death (where death is due to another AE) may be closed with the outcome 
“recovering/resolving” or “not recovered/not resolved”. Cases can be closed with the outcome 
of “recovering/resolving” when the subject has completed the follow-up period and is expected 
by the investigator to recover.
The investigator must ensure that the recording of the worst case severity and seriousness of an 
event is kept throughout the trial. A worsening of an unresolved AE must be reported as follow up 
with re-assessment of severity and/or seriousness of the event.
Queries or follow-up requests from Novo Nordisk must be responded to within 14 calendar days
from the date of receipt of the request, unless otherwise specified in the follow-up request.
SAEs after end of trial: If the investigator becomes aware of an SAE with a suspected causal 
relationship to the investigational medicinal product occurring to a subject after the subject has

Technical complaints and technical complaint samples
12.4.1
Reporting of technical complaints
All technical complaints on any of the following products: 
!
semaglutide 3 mg/7 mg/14 mg or placebo tablets
which occur from the time of first usage of the product until the time of the last usage of the 
product, must be collected and reported to Customer Complaint Center, Novo Nordisk.
Contact details (fax, e-mail and address) are provided in Attachment I to the protocol.
The investigator must assess whether the technical complaint is related to any AEs or SAEs.
Technical complaints must be reported on a separate technical complaint form:
!
One technical complaint form must be completed for each affected DUN
!
If DUN is not available, a technical complaint form for each code number must be completed.
The investigator must complete the technical complaint form in the eCRF within the following 
timelines of the trial site obtaining knowledge of the technical complaint:
!
Technical complaint assessed as related to an SAE within 24 hours
!
All other technical complaints within 5 calendar days
If the eCRF 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 eCRF becomes 
available again, the investigator must enter the information on the technical complaint form in the 
eCRF.
12.4.2
Collection, storage and shipment of technical complaint samples
The investigator must collect the technical complaint sample and notify the monitor within 5 
calendar days of obtaining the sample at trial site. The monitor must coordinate the shipment to 
Customer Complaint Center, Novo Nordisk (the address is provided in Attachment I) and ensure 
that the sample is sent as soon as possible. A copy of the technical complaint form must be included 
in the shipment of the sample. If several samples are returned in one shipment, the individual 
sample and the corresponding technical complaint form must be clearly separated.
The investigator must ensure that the technical complaint sample contains the code number and, if 
available, the DUN. All parts of the DUN should be returned.

If the technical complaint sample is unobtainable, the investigator must specify on the technical 
complaint form why it is unobtainable.
Storage of the technical complaint sample must be done in accordance with the conditions 
prescribed for the product.
12.5
Pregnancies in female subjects
Female subjects must be instructed to notify the investigator immediately if they become pregnant 
during the trial. The investigator must report any pregnancy in subjects who have received trial 
product(s).
The investigator must follow the pregnancy until the pregnancy outcome and the newborn infant is 
one month of age.
The investigator must report information about the pregnancy, pregnancy outcome and health of the 
newborn infant(s), as well as AEs in connection with the pregnancy and AEs in the foetus and 
newborn infant.
The following must be collected and reported by the investigator to Novo Nordisk - electronically 
(e.g. in PDF format), or by fax or courier:
1. Reporting of pregnancy information
Information about the pregnancy and pregnancy outcome/health of the newborn infant(s) has to 
be reported on Maternal Form 1A and 1B, respectively. 
When the pregnancy outcome is abnormal (i.e. congenital anomalies, foetal death including 
spontaneous abortion and/or any anomalies of the foetus observed at gross examination or 
during autopsy), and/or when a congenital anomaly is diagnosed within the first month, further 
information has to be reported for the female subject on Maternal Form 2. In addition, 
information from the male partner has to be reported on the Paternal Form, after an informed 
consent has been obtained from the male partner.
Initial reporting and follow-up information must be reported within 14 calendar days of the 
investigator’s first knowledge of initial or follow-up information.

2. Reporting of AE information
The investigator has to report AEs in connection with the pregnancy as well as in the foetus and 
newborn infant(s). The SAEs that must be reported include abnormal outcome, such as foetal 
death (including spontaneous abortion), and congenital anomalies (including those observed at 
gross examination or during autopsy of the foetus), as well as other pregnancy complications 
fulfilling the criteria of an SAE.
Forms and timelines for reporting AEs:
Non-serious AEs: 
–
AE forma within 14 calendar days of the investigator's first knowledge of the initial or 
follow-up information to the non-serious AE.
SAEs: 
–
AE forma within 24 hours of the investigator's first knowledge of the SAE.
–
Safety information form within 5 calendar days of the investigator's first knowledge of the 
SAE.
–
SAE follow-up information to the AE form and/or safety information form within 24 
hours of the investigator's first knowledge of the follow-up information.
a
It must be clearly stated in the AE diagnosis field on the AE form if the event occurred in 
the subject, foetus or newborn infant. If the AE occurred in the foetus or newborn infant, the 
AE can only be reported on paper AE and safety information form.
Any queries or follow-up requests from Novo Nordisk to non-serious AEs, SAEs and pregnancy 
forms must be responded to by the investigator within 14 calendar days from the date of receipt of 
the request, unless otherwise specified in the follow-up request.
12.6
Precautions and/or overdose
There are no specific antidotes to semaglutide. Treatment of an overdose should be symptomatic.
There is a potential risk of hypoglycaemia during dosing with semaglutide. The typical signs and 
symptoms of a non-severe hypoglycaemia include: hunger, slight headache, nausea, light-
headedness, palpitations and sweating. Symptoms of non-severe hypoglycaemia should be treated 
by ingestion of carbohydrates.
Severe hypoglycaemia resulting in loss of consciousness should be treated according to best 
available medical practise.
One case of accidental overdose of oral semaglutide was reported in the NN9924-3692 trial. The 
subject accidentally took the trial product 
 and was thus treated with 
 mg of

oral semaglutide. The subject did not report any symptoms and treatment was continued without 
any change.
One case of accidental overdose has been reported in subjects treated with s.c. semaglutide once 
weekly. The subject inadvertently injected  mg of semaglutide instead of 0.4 mg, which 
corresponds to a 
-fold higher dose than the maximum dose included in that trial. After 
 hours 
the subject felt nauseated, vomited and had a headache. The subject was instructed to drink 
sufficient amounts of fluids. 
 the subject 
wished to continue in the trial. No symptoms of hypoglycaemia or any other symptoms or signs 
were noted.
For further details please see the current edition of the Investigator’s Brochure for oral 
administration of semaglutide (NN9924), edition 624, and any updates hereof.
12.7
Committees related to safety
12.7.1
Novo Nordisk safety committee
Novo Nordisk will constitute an internal oral semaglutide safety committee to perform ongoing 
safety surveillance. The oral semaglutide 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.
12.7.2
Event adjudication committee
An independent external event adjudication committee (EAC) is established to perform validation 
of selected AEs according to pre-defined diagnostic criteria. The validation is based on review of 
pre-defined clinical data related to the specific AE. Pre-defined clinical data consist of copies of 
source documents collected and delivered by the investigational sites.
The EAC is composed of permanent members covering required medical specialities. EAC 
members must disclose any potential conflicts of interest and must be independent of Novo 
Nordisk.
The events are reviewed by the EAC in a blinded manner. The EAC will have no authorisations to 
impact on trial conduct, trial protocol or amendments.
The EAC works in accordance with written guidelines included in the EAC Charter describing in 
details the composition, tasks, responsibilities and work processes of the committee.
The events outlined in Table 12–2 have been selected for adjudication in order to obtain an external 
independent validation of the diagnosis. In addition, cardiovascular events are being adjudicated 
according to U.S. Food and Drug Administration (FDA) requirements48.

*Death is not a separate event, but an outcome
There are different processes for capturing events for adjudication:
!
Direct reporting by investigator:
–
All AEs need to be assessed by the investigator if any AE category is applicable. If the AE 
category selected is in scope for adjudication, the event specific adjudication form in the 
eCRF will be populated for sites to complete
–
AEs with fatal outcome
!
Screening: 
–
All AEs will be screened by Novo Nordisk for potential missed events for adjudication and 
if needed, the investigator will be asked to provide additional information such as an 
alternative aetiology, underlying cause(s) and/or clinical details.
–
All ECGs will be centrally read. If the central reading conclusion is suggestive of new 
myocardial infarction, the ECG adjudication form will be populated for sites to complete for 
all post-baseline ECGs.
!
EAC identified events:
–
The EAC can decide to have an AE adjudicated even if not initially reported as an event for 
adjudication by the investigator.

Event adjudication will be performed for AEs in randomised subjects including AEs with an onset 
date during the screening period. Event adjudication will not be performed for AEs in screening 
failures.
AEs for adjudication must be reported according to Section 12.2. In addition, the specific

knowledge of the AE and all relevant predefined documents provided within 4 weeks according to 
instructions in the event adjudication site manual.
The assessment made by the EAC will be included in the clinical trial report as well as the 
assessments made by the investigator. However, the adjudication made by the EAC, given its

13 Case report forms 
Novo Nordisk will provide a system for the eCRF. This system and support services to the system 
will be provided by an external supplier.
Ensure that all relevant questions are answered and that no empty data field exists. If a test or an 
assessment has not been done and will not be available, or if the question is irrelevant (e.g. is not 
applicable), indicate this according to the data entry instructions.
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 eCRF is revoked or if 
the eCRF is 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)).
On the paper CRF forms print legibly, using a ballpoint pen. Ensure that all questions are answered 
and that no empty data blocks exist. Ensure that no information is recorded outside the data blocks. 
If a test/assessment has not been done and will not be available, indicate this by writing "ND" (not 
done) in the appropriate answer field in the CRF. If the question is irrelevant (e.g. is not applicable) 
indicate this by writing "NA" (not applicable) in the appropriate answer field. Further guidance can 
be obtained from the instructions in the CRF.
The investigator must ensure that all information is consistent with the source documentation. By 
electronically signing the case book in the eCRF, the investigator confirms that the information in 
the eCRF and related forms is complete and correct.
13.1
Corrections to case report forms 
Corrections to the eCRF data may be made by the investigator or the investigator's delegated staff. 
An audit trail will be maintained in the eCRF 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 the investigator has signed 
the case book, the case book must be signed and dated again by the investigator.

data verification and validation purposes.
At the end of the trial, the investigator must ensure that all remaining data have been entered into 
the eCRF no later than 3 days after LSLV at the site in order to ensure the planned lock of the 
database.
Site specific eCRF data (in an electronic readable format) will be provided to the trial site before 
access to the eCRF is revoked. This data must be retained at the trial site. When the final clinical 
trial report is available, the data will be archived by Novo Nordisk.

14 Monitoring procedures
Monitoring will be conducted under a risk based approach.
During the course of the trial, the monitor will visit the trial site to ensure that the protocol is 
adhered to, that all issues have been recorded, to perform source data verification and to monitor 
drug accountability. The first monitoring visit will be performed as soon as possible after FSFV at 
the trial site and no later than 4 weeks after. The monitoring visit intervals will depend on the 
outcome of the remote monitoring of the eCRFs, the trial site's recruitment rate and the compliance 
of the trial site to the protocol and GCP, but will not exceed 12 weeks until LSLV at the trial site, 
for trial sites with active subjects (defined as subjects in screening, treatment or follow-up).
The monitor must be given direct access to all source 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).
All data must be verifiable in source documentation other than the eCRF.
For all data recorded the source document must be defined in a source document agreement at each 
trial site. There must only be one source defined at any time for any data element.
Source data generated by the trial site can be corrected by another person than the person entering 
the source data if accepted by local regulations; any correction must be explained, signed and dated 
by the person making the correction.
The original of the completed diaries and/or PROs must not be removed from the trial site, unless 
they form part of the eCRF and a copy is kept at the site.
The monitor will ensure that the eCRFs are completed and that paper CRFs are collected.
The following data will be source data verified for screening failures:
!
Date for obtaining informed consent.
!
Reason for screening failure
Monitors will review the subject’s medical records and other source data (e.g. the diaries and PROs) 
to ensure consistency and/or identify omissions compared to the eCRF. If discrepancies are found, 
the investigator must be questioned about these.

15 Data management
Data management is the responsibility of Novo Nordisk. Data management may be delegated under 
an agreement of transfer of responsibilities to a Contract Research Organisation.
Appropriate measures, including encryption of data files containing person identifiable data, will be 
used to ensure confidentiality of subject data, when they are transmitted over open networks.
Data from central laboratories will be transferred electronically. In cases where data is transferred 
via non-secure electronic networks, data will be encrypted during transfer.
The subject and any biological material obtained from the subject will be identified by subject 
number and trial ID. Appropriate measures such as encryption or leaving out certain identifiers will 
be enforced to protect the identity of subjects in all presentations and publications as required by 
local, regional and national requirements.

17 Statistical considerations
General considerations
If necessary, a statistical analysis plan may be written in addition to the protocol, including a more 
technical and detailed elaboration of the statistical analyses. The statistical analysis plan will be 
finalised before database lock.
The blinding of the randomised treatments will be maintained until the database has been released 
for statistical analysis.
Data from all sites will be analysed and reported together.
In statistical analyses where stratification is included, the three levels of antidiabetic background 
medication at screening (metformin, SU +/-metformin, basal insulin +/- metformin) and the two 
levels of renal function (eGFR 30 - 44 mL/min/1.73 m2 and eGFR 45 - 59 mL/min/1.73 m2 as per 
CKD-EPI) will be included based on the actual information collected through the eCRF. In case of 
missing eCRF information the information collected from the IWRS system will be used.
The latest available measurement, at or prior to the randomisation visit, will be used as the baseline 
measurement. If no measurement(s) have been obtained, at or prior to randomisation, the baseline 
value will be left missing.
Laboratory values below the lower limit of quantification (LLoQ) will be set to ½LLoQ. Number of 
values below LLoQ by treatment and visit will be summarised if deemed relevant.
Results from a statistical analysis will as a minimum be presented by the estimated treatment 
contrasts for oral semaglutide 14 mg vs. placebo with associated two-sided 95% confidence 
intervals and p-values corresponding to two-sided tests of no difference.
If no statistical analysis is specified, data will be presented using relevant summary statistics.
Primary and secondary estimands
Two estimands addressing different aspects of the trial objective will be defined; a primary de-facto 
(effectiveness) estimand and a secondary de-jure (efficacy) estimand:
!
Primary estimand
–
de-facto treatment difference (oral semaglutide versus placebo) at week 26 for all 
randomised subjects regardless of adherence to randomised treatment and initiation of 
rescue medication
The primary de-facto estimand assesses the expected glycaemic benefit in a future population that 
results from subjects initiating treatment with oral semaglutide including potential rescue

medication(s). Generalisation of this estimand depends among other things on the extent to which 
the use of rescue medication in this trial reflects clinical practice and the adherence to trial product 
administration in this trial reflects the behaviour of the target population. Accordingly, data 
collected regardless of discontinuation of trial product or initiation of rescue medication(s) will be 
used to draw inference.
!
Secondary estimand
–
de-jure treatment difference (oral semaglutide versus placebo) at week 26 for all 
randomised subjects if all subjects adhered to treatment and did not initiate rescue 
medication
The secondary de-jure estimand assesses the glycaemic benefit a future subject is expected to 
achieve if initiating and continuing treatment with oral semaglutide. It is considered a clinically 
relevant estimand as it provides information to treating clinicians about the expected glycaemic 
efficacy of oral semaglutide for purposes of treating individual subjects. Generalisation of this 
estimand depends among other things on the extent to which the adherence to trial product 
administration in this trial reflects the behaviour of the target population. Accordingly, only data 
collected prior to discontinuation of trial product or initiation of rescue medication will be used to 
draw inference. This will avoid confounding from rescue medication.
Missing data considerations at week 26
When estimating the primary estimand, the proportion of missing data, i.e., data that do not exist 
even though subjects are intended to stay in the trial regardless of treatment status and initiation of 
rescue medication(s), is expected to be maximum 10% based on the oral semaglutide phase 2 trial 
(NN9924-3790). Thus, missing data will mainly be due to withdrawal from trial or lost to follow-
up.
When estimating the secondary estimand, the proportion of missing data is expected to be higher 
(20%) since data collected after discontinuation of trial product or initiation of rescue medication(s) 
will be set to missing. The 20% of missing data is based on the oral semaglutide phase 2 trial 
(NN9924-3790) that indicates that a low starting dose with gradual dose escalation diminishes 
gastrointestinal AEs compared with more aggressive dosing regimens. Across treatment arms the 
main reasons for missing data are expected to be early treatment discontinuation due to 
gastrointestinal AEs and eventually initiation of rescue medication. Initiation of rescue medication 
is expected to be more frequent in the placebo arm. Whereas a higher proportion of subjects are 
expected to discontinue treatment due to AEs in the oral semaglutide arm. So overall the frequency 
of missing data is expected to be similar across treatment arms.
Descriptive summaries and graphical representation of extent, reason(s) for and pattern of missing 
data will be presented by treatment arm.

Sample size calculation
Both the primary endpoint, change from baseline to week 26 in HbA1c and the confirmatory
secondary endpoint, change from baseline to week 26 in body weight are planned to be tested for
superiority of oral semaglutide vs. placebo.
The sample size calculation is made to ensure a power of at least 90% for testing HbA1c superiority
of oral semaglutide vs. placebo out of the two pre-specified confirmatory hypotheses shown in 
Figure 17–1. The hierarchical testing procedure is used to control the overall type I error at a 
nominal two-sided 5% level. The statistical testing strategy is built on the principle that glycaemic 
effect will have to be established in terms of HbA1c superiority before testing for added benefits in 
terms of body weight superiority.
The sample size is calculated using the calcPower function in the R package, gMCP50, using 10000 
simulations. The two pre-specified confirmatory tests are assumed to be independent. Since some of 
the tests are positively correlated, the assumption of independence is viewed as conservative.
The sample size assumptions for treatment effects (TE), adjusted treatment effects and the standard 
deviation (SD) are given in Table 17–1. These are based on the oral semaglutide phase 2 results 
(NN9924-3790) and supported by results from the s.c. semaglutide phase 2 trial (NN9535-1821).
Subjects are allowed to be on metformin and/or SU, basal insulin alone or metformin in 
combination with basal insulin as background medication; if they need rescue medication it is 
expected to have an effect on glycaemic control and the treatment effect compared to oral 
semaglutide will therefore be equalised. Furthermore a conservative approach for handling of 
missing data will be performed. An adjustment in treatment effect will be implemented for the 10% 
of subjects who are expected to discontinue trial product or initiate rescue medication and for the 
10% of subjects who are expected to have actual missing data. The treatment effects used in the 
sample size calculation will be adjusted according to no effect in these subjects. The adjusted 
treatment effect for testing superiority is defined as:

With the above assumptions, allocating 162 subjects to each of the oral semaglutide and placebo 
arms provides at least 90% power to confirm HbA1c superiority of oral semaglutide vs. placebo. In 
total 2×162 = 324 subjects are planned to be randomised.
Calculated powers for individual hypotheses are presented in Table 17–2.

Data selections and observation periods
Unless subjects withdraw their informed consent, data collection will continue for the full duration 
of the trial. The full duration of the trial is defined as up to and including:
!
the follow-up visit (V14) for subjects on trial product
!
the latest occurring visit of the end-of-treatment visit (V13) or the follow-up premature 
discontinuation visit (V14A), for subjects who have discontinued trial product prematurely.
Subjects and data to be used in an analysis will be selected in a two-step manner:
!
Firstly, subjects will be selected based on the specified analysis set
!
Secondly, data points on the selected subjects from the first step will be selected based on the 
specified observation period
Definition of the observation periods:
In-trial: This observation period represents the time period where subjects are considered to be in 
the trial, regardless of discontinuation of trial product or initiation of rescue medication. The in-trial 
observation period starts at randomisation (as registered in the IWRS) and ends at the date of:
!
the last direct subject-site contact, which is scheduled to take place 5 weeks after planned last 
dose of trial product at the follow-up visit
!
withdrawal for subjects who withdraw their informed consent
!
the last subject-investigator contact as defined by the investigator for subjects who are lost to 
follow-up
!
death for subjects who dies before any of the above
On-treatment: This observation period represents the time period where subjects are considered 
treated with the trial product. The observation period is a subset of the in-trial observation period. It 
starts at the date of first dose of trial product. Two slightly different end dates will be needed to 
cover all assessments appropriately.
For adjudicated events, ECGs, anti-semaglutide antibodies, and AEs including hypoglycaemic 
episodes, the observation period ends at the first date of any of the following:
!
the follow-up visit (V14)
!
the follow-up prematurely discontinuation visit (V14A)
!
the last date on trial product +38 days
!
the end-date for the in-trial observation period
The follow-up visit is scheduled to take place 5 weeks after the last date on trial product 
corresponding to approximately five half-lives of oral semaglutide. The visit window for the 
follow-up visit is +3 days.

For efficacy and other safety assessments (laboratory assessments, physical examination and vital 
signs) the observation period ends at the last date on trial product +3 days. This will be used in 
order to ensure specificity to reversible effects of treatment.
On-treatment without rescue medication: This observation period is a subset of the on-treatment 
observation period, where subjects are considered treated with trial product, but have not initiated 
any rescue medications. Specifically it starts at date of first dose of trial product and the observation 
period ends at the first date of any of the following:
!
the last dose of trial product +3 days
!
initiation of rescue medication
The in-trial observation period will be the primary observation period when estimating the primary 
estimand. The on-treatment without rescue medication observation period will be the primary 
observation period when estimating the secondary estimand. The on-treatment observation period 
will be considered supportive for evaluating efficacy. Safety will be evaluated based on the in-trial 
and the on-treatment observation periods.
Data points collected outside an observation period will be treated as missing in the analysis. 
Baseline data will always be included in an observation period. For adjudicated events, the onset 
date will be the EAC adjudicated onset date.
Before data are locked for statistical analysis and the randomisation code is broken, a review of all 
data will take place. Any decision to exclude either a subject or single observations from the 
statistical analysis is the joint responsibility of the members of the Novo Nordisk study group. 
Exclusion of data from analyses will be used restrictively, and normally no data should be excluded 
from the FAS. The subjects or observations to be excluded, and the reasons for their exclusion must 
be documented and signed by those responsible before database lock. The subjects and observations 
excluded from analysis sets, and the reason for this, will be described in the clinical trial report.
Confirmatory hypotheses 
For the primary HbA1c endpoint and the secondary confirmatory body weight endpoint, the 
following one-sided hypotheses are planned to be tested for oral semaglutide versus placebo. Let 
the mean treatment difference be defined as μ = (oral semaglutide minus placebo):
!
HbA1c superiority
–
H0: μ ≥0.0%-point against Ha: μ < 0.0%-point
!
Body weight superiority
–
H0: μ ≥0.0 kg against Ha: μ < 0.0 kg
Operationally the hypotheses will be evaluated by two-sided tests at the 5% significance level.

Multiplicity and criteria for confirming hypotheses
The type I error for testing the two confirmatory hypotheses related to the HbA1c and body weight 
endpoints will be preserved in the strong sense at 5% (two-sided) using the hierarchical testing 
strategy as outlined in Figure 17–1.
Superiority will be considered confirmed if the mean treatment difference is supporting the 
corresponding alternative hypothesis and the two-sided p-value from the primary analysis of the 
primary estimand is strictly below the 5% two-sided significance level. This is equivalent to using a 
one-sided p-value (nominal α = 0.025) and a one-sided 2.5% overall significance level.
17.3
Primary endpoint
The primary endpoint is change from baseline to week 26 in HbA1c.
17.3.1
Primary analysis for the primary estimand
The primary estimand will be estimated based on the FAS using week 26 measurements from the 
in-trial observation period. The primary statistical analysis will be a pattern mixture model using 
multiple imputation to handle missing data assuming that the missing data mechanism is missing at 
random (MAR) within the groups used for imputation. Imputation of missing data at week 26 will 
be done within 4 groups of subjects defined by randomised treatment arm, and whether subjects at 
week 26; (i) have discontinued treatment or initiated rescue medication or (ii) are still on treatment 
and have not initiated rescue medication. It is hereby assumed that the likely values of what the 
missing data would have been if available are best described by information from subjects who at 
week 26 are similar in terms of randomised treatment arm and treatment adherence/rescue 
medication status.
Missing values for each group will be imputed as follows:
!
An analysis of covariance (ANCOVA) with region, stratification factors and the interaction 
between the two stratification factors as categorical fixed effects and baseline HbA1c
measurement as a covariate will be fitted to observed values of the change from baseline in 
HbA1c at week 26.
!
The estimated parameters for location and dispersion will be used to impute 100 values for each 
subject with missing week 26 data based on region, stratification factors, the interaction 
between the two stratification factors and baseline HbA1c. Thus, 100 complete data sets will be 
generated including observed and imputed values.
Analysis used for confirming superiority versus placebo at week 26:
For each of the 100 (now complete) imputed data sets, the change in HbA1c from baseline to week 
26 will be analysed using an ANCOVA with treatment, stratification factors, the interaction 
between the two stratification factors and region as categorical fixed effects and baseline HbA1c as

covariate. The results obtained from analysing the datasets will be combined using Rubin’s rule51 to 
draw inference.
17.3.2
Primary analysis for the secondary estimand
The secondary estimand will be estimated based on the FAS using post-baseline measurements up 
to and including week 26 from the on-treatment without rescue medication observation period. The 
primary analysis for the secondary estimand will be a Mixed Model for Repeated Measurements 
(MMRM). A restricted maximum likelihood (REML) will be used. The model will include all post 
baseline HbA1c measurements collected at scheduled visits up to and including week 26 as 
dependent variables. The independent effects included in the model will be treatment, stratification 
factors, the interaction between the two stratification factors and region as categorical fixed effects 
and baseline HbA1c as a covariate, all nested within visit. An unstructured covariance matrix for 
HbA1c measurements within the same subject will be employed, assuming measurements from 
different subjects are independent.
The MMRM is a well-established method that accounts for the uncertainty pertaining to missing 
data. This analysis assumes that the missing data mechanism is MAR. Under this assumption the 
statistical behaviour of the missing data (given the observed responses and model fixed effects and 
covariates) is assumed to be same as the observed data.
17.3.3
Sensitivity analyses
To investigate the sensitivity of the primary analysis results, complementary and separate analyses 
will be performed for the primary and secondary estimand. In line with European Medicines 
Agency recommendations52 and with a report from the US National Research Council53, these 
analyses will primarily evaluate the sensitivity of the results due to the impact of missing data.
The evaluation of the robustness of the primary analysis results will primarily be based on a pattern 
mixture model approach using multiple imputation. An overview of the sensitivity analyses for each 
of the estimands are specified below followed by a more detailed description of the three different 
pattern mixture models used. Finally, one additional sensitivity analysis will be described that are 
not based on the pattern mixture model approach, see Section 17.3.3.2.

17.3.3.1
Pattern mixture models
Common for the three pattern mixture model sensitivity analyses is that they all aim to stress-test 
the primary HbA1c results by changing the assumptions for part or all missing data in the oral 
semaglutide treatment arms, while maintaining the missing at random data assumption for the 
placebo arm:
!
Comparator multiple imputation analysis: In this sensitivity analysis missing data at week 26 
for all subjects will be imputed to resemble the distribution of the week 26 values observed in 
the placebo treatment arm. In effect, this imputation approach removes the treatment difference 
between oral semaglutide and placebo for all subjects randomised to oral semaglutide, given 
that oral semaglutide is better than placebo.
!
Comparator multiple imputation analysis differentiating between reasons for discontinuing 
treatment prematurely: In this sensitivity analysis only missing data at week 26 for subjects who 
discontinue oral semaglutide treatment due to treatment related AE(s) will be imputed to 
resemble the distribution of the week 26 values observed in the placebo treatment arm. 
Treatment related AEs are defined as AEs classified as possible or probable related to trial 
product as reported by the investigator. In effect this imputation approach removes the treatment 
difference between oral semaglutide and placebo for this selected group of subjects randomised

to oral semaglutide. This sensitivity analysis is less conservative as compared to the first 
sensitivity analysis.
!
Tipping-point multiple imputation analysis: In this sensitivity analysis, missing data will first be 
imputed according to the primary analysis. Secondly, for the oral semaglutide treatment arm a 
penalty will be added to the imputed values at week 26. The approach is to gradually increase 
this penalty until a confirmed HbA1c conclusion from the primary analysis is changed. The 
specific value of the penalty that changes the conclusion will be used to evaluate the robustness 
of the primary analysis result.
17.3.3.2
Other sensitivity analyses
!
Last observation carried forward (LOCF) analysis: This sensitivity analysis will be based on 
the FAS using the on-treatment without rescue medication observation period. The change from 
baseline to week 26 in HbA1c will be analysed by a linear normal model (ANCOVA) with 
treatment, stratification factors, the interaction between the two stratification factors and region 
as categorical fixed effects and baseline HbA1c as a covariate.
17.3.3.3
Assessment of sensitivity analyses
The results from the sensitivity analyses will be collectively used to interpret the robustness of the 
trial results for HbA1c. Due to the sensitivity analyses inherent conservative nature, it will not be a 
requirement that all confirmatory hypotheses are consistently confirmed across the sensitivity 
analyses. Thus, no absolute success criteria will be pre-defined for each sensitivity analysis. The 
sensitivity results in totality will be used to substantiate the credibility of the trial results.
17.4
Secondary endpoints
17.4.1
Confirmatory secondary endpoints
Change from baseline to week 26 in body weight (kg) will be a confirmatory secondary endpoint.
The primary and secondary estimands will be estimated using the same approaches as described for 
the primary HbA1c endpoint. Body weight will only be tested for superiority. Baseline body weight 
will be used as a covariate instead of baseline HbA1c in both the multiple imputation and MMRM 
analysis models.
Superiority will be considered confirmed if the mean treatment difference is supporting the 
corresponding hypothesis and the two-sided p-value from the analysis of the primary estimand is 
strictly below its updated local two-sided significance level resulting from the closed testing
procedure in Figure 17–1. Sensitivity analyses similar to the ones pre-specified for testing 
superiority for the primary HbA1c endpoint will be made to evaluate the robustness of the body 
weight results.

Efficacy endpoints
The below supportive secondary efficacy endpoints will be evaluated for
!
the primary estimand based on FAS using the in-trial observation period
!
the secondary estimand based on FAS using the on-treatment without rescue medication 
observation period
No sensitivity analyses are planned for the supported secondary endpoints.
Continuous efficacy endpoints
Change from baseline to week 26 in:
!
Fasting plasma glucose (FPG)
!
Body weight (%)
!
Body mass index (BMI)
!
Waist circumference
!
Fasting lipid profile (total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density 
lipoprotein (HDL) cholesterol and triglycerides)
!
C-reactive protein (CRP)
BMI will be calculated based on body weight and height based on the formulae:
BMI kg/m2 = body weight (kg)/(height (m) x height (m)) or (kg/m2 = [lb/in2 x 703])
The above continuous endpoints will be analysed separately using similar model approaches as for 
the primary endpoint with the associated baseline response as a covariate. Fasting lipid profile 
endpoints will be log-transformed prior to analysis with the associated log-transformed baseline 
value as a covariate.
For evaluation of the primary estimand, the analyses will be performed at week 26. This will result 
in imputation of missing data within 4 groups as described for the week 26 evaluation in Section
17.3.1.
For evaluation of the secondary estimand, the MMRM based primary analysis will include all 
scheduled post-baseline measurement up to and including week 26. From this model the estimated 
treatment differences (ratios) will be presented at week 26 with 95% confidence intervals and 
two-sided p-values for test of no difference.

Binary efficacy endpoints
If a subject after week 26 achieves (yes/no):

HbA1c < 7.0% (53 mmol/mol) (ADA) target
!
HbA1c ≤ 6.5% (48 mmol/mol) (AACE) target

HbA1c < 7.0% (53 mmol/mol) without hypoglycaemia (treatment-emergent severe or blood 
glucose-confirmed symptomatic hypoglycaemia) and no weight gain
!
HbA1c reduction ≥ 1%-point (10.9 mmol/mol) and weight loss ≥ 3%
The above eight binary endpoints will be analysed using a logistic regression model with treatment 
and region as fixed effects and baseline response as covariate (i.e. baseline HbA1c for binary HbA1c
endpoints, baseline weight for weight endpoints and both baseline HbA1c and baseline weight for 
the binary endpoints that combines both parameters). To account for missing data, the analysis will 
be made using a sequential multiple imputation approach as described below:
!
Multiple imputed data sets (100) will be created in which missing values for the underlying 
continuous assessments are imputed by treatment group and treatment adherence/rescue status 
assuming MAR and as described in Section 17.3.1 for the primary estimand and by treatment 
group assuming MAR and as described in Section 17.3.2 for the secondary estimand.

Each of the created complete data set will be analysed with the logistic model and inference will 
be drawn using Rubin’s rule51.
Time to event endpoint

Time to rescue medication
The endpoint will be analysed based on FAS using both the on-treatment observation period and the 
in-trial observation period. For the analysis based on the on-treatment observation period, subject 
without need for rescue medication during the on-treatment observation period will be censored at 
the time point of the date of last trial product. For the in-trial period subject without need for 
addition of glucose-lowering medication during the in-trial observation period, will be censored at 
the time point of the date of end of the in-trial observation period. For this analysis, the follow-up 
period will be excluded from the in-trial observation period, since subjects will have to stop

observation periods in Section 17.2).
TEAEs will be summarised in terms of the number of subjects with at least one event (N), the 
percentage of subjects with at least one event (%), the number of events (E) and the event rate per 
100 patient years of observation time (R) for the on-treatment observation period. Supportive

the episode occurs within the on-treatment observation period (see definition of observation periods 
in Section 17.2).
Nocturnal hypoglycaemic episodes: episodes occurring between 00:01 and 05.59 both inclusive.
Hypoglycaemic episodes are classified according to the Novo Nordisk classification of 
hypoglycaemia and the ADA classification of hypoglycaemia (see Figure 17–2).
Novo Nordisk classification of hypoglycaemia
In normal physiology, symptoms of hypoglycaemia occur below a plasma glucose level of 
3.1 mmol/L (56 mg/dL)54. Therefore, Novo Nordisk has included hypoglycaemia with plasma 
glucose (PG) levels below this cut-off point in the definition of blood glucose (BG) confirmed 
hypoglycaemia.
Novo Nordisk uses the following classification in addition to the ADA classification:
!
Severe or BG-confirmed symptomatic hypoglycaemia: An episode that is severe according to 
the ADA classification43 or BG-confirmed by a plasma glucose value < 3.1 mmol/L (56 mg/dL) 
with symptoms consistent with hypoglycaemia.

ADA classification43 of hypoglycaemia
!
Severe hypoglycaemia: An episode requiring assistance of another person to actively administer 
carbohydrate, glucagon, or take other corrective actions. Plasma glucose concentrations may not 
be available during an event, but neurological recovery following the return of plasma glucose 
to normal is considered sufficient evidence that the event was induced by a low plasma glucose 
concentration.
!
Asymptomatic hypoglycaemia: An episode not accompanied by typical symptoms of 
hypoglycaemia, but with a measured plasma glucose concentration ≤3.9 mmol/L (70 mg/dL).
!
Documented symptomatic hypoglycaemia: An episode during which typical symptoms of 
hypoglycaemia are accompanied by a measured plasma glucose concentration 
≤3.9 mmol/L (70 mg/dL).
!
Pseudo-hypoglycaemia: An episode during which the person with diabetes reports any of the 
typical symptoms of hypoglycaemia with a measured plasma glucose concentration 
> 3.9 mmol/L (70 mg/dL) but approaching that level.
!
Probable symptomatic hypoglycaemia: An episode during which symptoms of hypoglycaemia 
are not accompanied by a plasma glucose determination but that was presumably caused by a 
plasma glucose concentration ≤3.9 mmol/L (70 mg/dL).

Data on treatment-emergent hypoglycaemic episodes will be presented in terms of the number of 
subjects with at least one episode, the percentage of subjects with at least one episode (%), the total 
number of episodes and the episode rate per 100 patient years of observation time.
Analysis of severe or BG-confirmed symptomatic hypoglycaemic endpoints
The number of treatment-emergent severe or BG-confirmed symptomatic hypoglycaemic episodes 
will be evaluated for the on-treatment period using a negative binomial regression model with a log-
link function and the logarithm of the duration of the subject’s on-treatment observation period as 
offset. The model will include treatment, stratification factors, the interaction between the two 
stratification factors and region as fixed factors and baseline HbA1c as covariate.
The binary endpoint showing whether a subject has at least one treatment emergent severe or BG-
confirmed symptomatic hypoglycaemic episode will be analysed using a logistic regression model 
with treatment, stratification factors, the interaction between the two stratification factors and region 
as fixed factors and baseline HbA1c as covariate.

18.1
Benefit-risk assessment of the trial
18.1.1
Risks and precautions
The nonclinical safety programme of oral semaglutide has not revealed any safety issues precluding 
use in humans.
The sections below describe the important identified and potential risks and precautions associated 
with oral semaglutide treatment. These are based on findings in nonclinical studies and clinical 
trials with oral semaglutide as well as other GLP-1 RAs. For each of these risks and precautions, 
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 AEs in clinical trials 
with oral semaglutide have been gastrointestinal disorders (nausea, vomiting, diarrhoea, dyspepsia 
and constipation). Clinical trials have indicated that a low starting dose and gradual dose escalation 
mitigates the risk of gastrointestinal AEs. Consequently, a low starting dose and dose escalation 
with 4 week dose-escalation steps have been implemented in the trial.
Potential risks
Medullary thyroid cancer
The human relevance of the proliferative C-cell changes found in rodents treated with GLP-1 RAs 
is unknown, but data suggest that rodents are more sensitive to the mode of action of GLP-1 RAs 
for induction of C-cell tumours. However, as a precaution, subjects with a family or personal 
history of Multiple Endocrine Neoplasia Type 2 or Medullary Thyroid Carcinoma will not be 
enrolled in the trial. During the trial, calcitonin will be measured on a regular basis, and the 
guidance for investigators on further evaluation and action on elevated calcitonin concentrations is 
included in appendix A.
Acute pancreatitis
Acute pancreatitis has been reported in subjects treated with GLP-1 RAs including oral 
semaglutide. As a precaution, subjects with a history of acute or chronic pancreatitis will not be 
enrolled in the trial. Also, subjects will be informed about the symptoms of acute pancreatitis and 
serum levels of lipase and amylase will be monitored throughout the trial.

Pancreatic cancer
Patients with T2DM have an increased risk of certain types of cancer such as pancreatic cancer. 
There is currently no support from nonclinical studies or clinical trials or post-marketing data that 
GLP-1-based therapies increase the risk of pancreatic cancer. However, pancreatic cancer has been 
included as a separate potential risk due to the scientific debate surrounding a potential association 
to GLP-1-based therapies and the unknown long-term effects of stimulation of β-cells and 
suppression of α-cells. Pancreatic cancer has been classified as a potential class risk of GLP-1 RAs 
by the European Medicines Agency.
Allergic reactions
As in the case with all protein-based pharmaceuticals, treatment with oral semaglutide may evoke 
allergic reactions. These may include urticaria, rash, pruritus as well as anaphylactic reactions. As a 
precaution, subjects with known or suspected hypersensitivity to trial product(s) or related products 
will not be enrolled in the trial. In addition, subjects will be instructed to contact the site staff as 
soon as possible for further guidance if suspicion of a hypersensitivity reaction to the trial product 
occurs.
Hypoglycaemia
Based on current knowledge about the GLP-1 RA drug class, there is a risk of hypoglycaemic 
episodes. Hypoglycaemic episodes have mainly been observed when a GLP-1 RA is combined with 
SU or insulin. The risk for development of hypoglycaemia with oral semaglutide in combination 
with SU and insulin is currently unknown.
Acute renal impairment
In subjects treated with GLP-1 RAs including oral semaglutide, gastrointestinal AEs such as 
nausea, vomiting and diarrhoea may lead to significant dehydration and secondary acute renal 
impairment. Subjects with gastrointestinal AEs are recommended to drink plenty of fluids to avoid 
volume depletion. Also, serum creatinine and other markers of kidney function will be monitored 
throughout the trial.
Impaired renal function may increase the risk of metformin-associated lactic acidosis when GLP-1 
RAs are co-administered with metformin. As a precaution, serum creatinine will be measured 
regularly. In subjects treated with metformin who experience prolonged or severe nausea and 
vomiting, the investigator should monitor serum creatinine, and if clinically indicated, withhold 
metformin until resolution of renal dysfunction.
The use of the background medication should be in accordance with the current approved labels.

Other safety considerations
Teratogenicity (embryo-foetal development toxicity)
Semaglutide caused embryo-foetal malformations in the rat through a GLP-1 receptor mediated 
effect on the inverted yolk sac placenta leading to impaired nutrient supply to the developing 
embryo. Primates do not have an inverted yolk sac placenta which makes this mechanism unlikely 
to be of relevance to humans. However, as a precaution, females who are pregnant, breast-feeding 
or intend to become pregnant or are of childbearing potential and not using an adequate 
contraceptive method will not be enrolled in the trial. In addition, pregnancy tests will be performed 
at all visits, including screening and follow-up and at any time during the trial if a menstrual period 
is missed, or as required by local law.
General precautions
All subjects will be included after a thorough evaluation with regards to in- and exclusion criteria
defined in order to ensure that subjects are eligible for trial treatment. 
There are also strict glyacemic rescue criteria in place to ensure acceptable glycaemic control 
during the trial. If rescue medication is required, it should be in accordance with ADA/European 
Association for the Study of Diabetes31, 32 (excluding GLP-1 RAs, DPP-4 inhibitors, amylin 
analogues and SGLT-2 inhibitors).
It is the responsibility of the investigator to ensure the best possible care according to the principles 
outlined in Diabetes Care 2016 Standards of Medical Care in Diabetes.55
Further details with regards to safety of trial product are described in the current edition of the 
Investigator’s Brochure for oral semaglutide (NN9924)24, or any updates thereto.
18.1.2
Benefits
In this trial, subjects will be randomised in a 1:1 manner to either oral semaglutide or placebo as 
add on to their current background medication (metformin and/or SU, basal insulin alone or 
metformin in combination with basal insulin). Subjects will therefore, for the majority of the trial 
periode, be treated with a regime anticipated to be better than or equal to the treatment they received 
at the time of entry into the trial. Based on the results of the phase 2 dose finding trial, oral 
semaglutide is expected to provide clinically relevant improvements in glycaemic control and body 
weight in subjects with type 2 diabetes.
In addition, it is expected that all subjects, including subjects randomised to placebo, will benefit 
from participation through close contact with the trial site, with close follow-up of their T2DM and 
a careful medical examination; all of which will most likely result in an intensified management of 
their T2DM.

18.1.3
Risk and benefit conclusion
The safety profile for oral semaglutide generated from the clinical and nonclinical development 
programme has not revealed any safety issues that would prohibit administration of oral 
semaglutide in accordance with the planned clinical trial. The phase 2 results indicate that oral 
semaglutide will provide clinically relevant improvements in glycaemic control and body weight.
Safety and efficacy will be monitored regularly and acceptable glycaemic control will be reinforced
at all times during the trial.
In conclusion, the potential risk to the subjects in this trial is considered low and acceptable in view 
of the anticipated benefits oral semaglutide will provide to subjects with T2DM.
18.2
Informed consent
In seeking and documenting informed consent, the investigator must comply with applicable 
regulatory requirements and adhere to ICH GCP1 and the requirements in the Declaration of 
Helsinki2.
Before any trial-related activity, the investigator must give the subject verbal and written 
information about the trial and the procedures involved in a form that the subject can read and 
understand.
The subjects must be fully informed of their rights and responsibilities while participating in the 
trial as well as possible disadvantages of being treated with the trial products.
The investigator must ensure the subject ample time to come to a decision whether or not to 
participate in the trial.
A voluntary, signed and personally dated informed consent must be obtained from the subject 
before any trial-related activity.
The responsibility for seeking informed consent must remain with the investigator, but the 
investigator may delegate the task to a medically qualified person, in accordance with local 
requirements. The written informed consent must be signed and personally dated by the person who 
seeks the informed consent before any trial-related activity.
If information becomes available that may be relevant to the subject’s willingness to continue 
participating in the trial, the investigator must inform the subject in a timely manner and a revised 
written subject information must be provided and a new informed consent must be obtained.

In order to avoid missing data, the subjects will be informed about the importance of completing the 
trial also if the subjects discontinue from trial product.
18.3
Data handling
If the subject withdraws from the trial or is lost to follow-up, then the subject’s data will be handled 
as follows:
!
Data already collected and any data collected at the end-of-trial visit including follow-up visits
will be retained by Novo Nordisk, entered into the database and used for the clinical trial report.
!
Safety events will be reported to Novo Nordisk and regulatory authorities according to 
local/national requirements.
If data is used, it will always be in accordance with local regulations and IRBs/IECs.
18.4
Information to subjects during trial
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.
18.5
Premature termination of the trial and/or trial site
Novo Nordisk, the IRBs/IECs or a regulatory authority may decide to stop the trial, part of the trial 
or a trial site at any time, but agreement on procedures to be followed must be obtained.
If the trial is suspended or prematurely 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. 
If, after the termination of the trial, the benefit-risk analysis changes, the new evaluation must be 
provided to the IRBs/IECs in case it has an impact on the planned follow-up of subjects who have 
participated in the trial. If it has an impact, the actions needed to inform and protect the subjects 
should be described.

19 Protocol compliance
19.1
Protocol deviations
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 eCRF or via listings from the trial database.
Documentation on protocol deviations must be kept in the investigator trial master file and sponsor 
trial master file.
19.2
Prevention of missing data
The importance of subject retention will be addressed by Novo Nordisk in the training and 
communication with the trial sites.
The subjects will be carefully informed about the trial procedures before signing informed consent, 
so that they know the implications of participating in the trial.
Close surveillance of subject retention will be performed throughout the trial by Novo Nordisk with 
focus on reasons for premature discontinuation of trial product or withdrawal of consent to secure 
early mitigations in collaboration with the trial sites. 
The investigator will make every effort to ensure that all assessments are performed and data is 
collected. If missing data does occur the reason will be collected via the protocol deviation process, 
see Section 19.1. Novo Nordisk will monitor protocol deviations on an on-going basis throughout 
the trial followed by appropriate actions (e.g. re-training of site staff).

22 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 will follow instructions from Novo Nordisk when processing data.
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 data 
produced) in the investigator trial master file. The documents including the subject identification 
code list must be kept in a secure locked facility, so 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 medical 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).

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. All authors will be given the relevant 
statistical tables, figures and reports needed to evaluate the planned publication. 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.
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.
Novo Nordisk maintains the right to be informed of plans by any investigator to publish and to 
review any scientific paper, presentation, communication or other information concerning the 
investigation described in this protocol. Any such communication must be submitted in writing to 
Novo Nordisk before submission for comments. Comments will be given within four weeks from 
receipt of the planned communication.
23.1.1
Authorship
Authorship of publications should be in accordance with the Uniform Requirements of the 
International Committee of Medical Journal Editors56 (sometimes referred to as the Vancouver 
Criteria). Novo Nordisk will appoint investigator(s) to prepare publications in collaboration with 
Novo Nordisk.
23.1.2
Site-specific publication(s) by investigator(s)
For a multi-centre 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. It is a Novo Nordisk policy that 
such individual reports do not precede the primary manuscript and should always reference the 
primary manuscript of the trial.
Novo Nordisk reserves the right to prior review of such publications. Further to allow for the 
primary manuscript to be published as the first, Novo Nordisk asks for deferment of publication of 
individual site results until the primary manuscript is accepted for publication. As Novo Nordisk 
wants to live up to the industry publication policy, submission of a primary publication will take 
place no later than 18 months after trial completion.
23.2
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 research subjects' data, and will be provided with the 
randomisation code after results are available.

24 Retention of clinical trial documentation and human biosamples
24.1
Retention of clinical trial documentation
Subject’s medical records must be kept for the maximum period permitted by the hospital, 
institution or private practice.
The investigator must agree to archive the documentation (this includes both electronic and paper-
based records) pertaining to the trial in an archive after completion or discontinuation of the trial if 
not otherwise notified. The investigator should not destroy any documents without prior permission 
from Novo Nordisk. If the investigator cannot archive the documents at the trial site, Novo Nordisk 
can refer the investigator to an independent archive provider that has a system in place to allow only 
the investigator to access the files.
The investigator must be able to access his/her trial documents without involving Novo Nordisk in 
any way. Site-specific CRFs and other subject data (in an electronic readable format or as paper 
copies or prints) will be provided to the investigator before access is revoked to the systems and/or 
electronic devices supplied by Novo Nordisk. These data must be retained by the trial site. If the 
provided 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.
Novo Nordisk will maintain Novo Nordisk documentation pertaining to the trial for at least 20 years 
after discontinuation of the marketing authorisation, termination of the trial or cancellation of the 
research project whichever is longest. 
The files from the trial site/institution must be retained for 15 years after end of trial as defined in 
Section 7, or longer if required by local regulations or Novo Nordisk. In any case trial files cannot 
be destroyed until the trial site/institution is notified by Novo Nordisk. The deletion process must 
ensure confidentiality of data and must be done in accordance with local regulatory requirements.
24.2
Retention of human biosamples
Antibody samples may be retained for later analysis for further characterisation of antibody 
responses towards drug if required by health authorities or for safety reasons.
The samples will be stored at a central bio-repository 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.
The subject’s identity will remain confidential and the antibody 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.

25 Institutional Review Boards/Independent Ethics Committees and 
regulatory authorities
IRB/IEC:
Written approval or favourable opinion must be obtained from IRB/IEC prior to commencement of 
the trial.
During the trial, the investigator or Novo Nordisk, as applicable, must promptly report the 
following to the IRB/IEC, in accordance with local requirements: updates to Investigator´s 
Brochure, unexpected SAEs where a causal relationship cannot be ruled out, protocol amendments 
according to local requirements, deviations to the protocol implemented to eliminate immediate 
hazards to the subjects, new information that may affect adversely the safety of the subjects or the 
conduct of the trial (including new benefit-risk analysis in case it will have an impact on the 
planned follow-up of the subjects), annually written summaries of the trial status, and other 
documents as required by the local IRB/IEC.
The investigator must ensure submission of the clinical trial report synopsis to the IRB/IEC.
Protocol amendments must not be implemented before approval or favourable opinion according to 
local regulations, unless necessary to eliminate immediate hazards to the subjects.
The investigator must maintain an accurate and complete record of all submissions made to the 
IRB/IEC. The records must be filed in the investigator trial master file and copies must be sent to 
Novo Nordisk.
Regulatory Authorities:
Regulatory authorities will receive the clinical trial application, protocol amendments, reports on 
SAEs and the clinical trial report according to national requirements.

Background
Treatment with GLP-1 receptor agonists has 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 elevated calcitonin 
levels (greater than 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
!
smoking
!
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 co-morbidities) 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 1 and described 
below should be followed. The algorithm applies for all calcitonin values in the trial.
Calcitonin < 10ng/L
Calcitonin  ≥ 10 ng/L and 
< 50 ng/L
Calcitonin  ≥ 50 ng/L and 
< 100 ng/L
Calcitonin  ≥ 100 ng/L
Evaluation of 
calcitonin results
Calcitonin  ≥ 10 ng/L and 
last measurement in the 
trial
No action
●Investigate potential confounding 
factors
●Continue sampling of calcitonin 
according to protocol
●Refer to thyroid specialist
●Discontinue trial product
●Refer to thyroid specialist
●Refer to thyroid specialist

Flow of calcitonin monitoring
2.1
Calcitonin ≥ 100 ng/L
Action: The subject must immediately be referred to a thyroid specialist for further evaluation and 
the trial product must be discontinued (see protocol Section 6.5 premature discontinuation of trial 
product). 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 disease.1 All of these patients were diagnosed with medullary thyroid carcinoma resulting 
in a positive predictive value of 100%.
Diagnostic evaluation should include:
!
thyroid ultrasound examination
!
fine needle aspiration of any nodules > 1 cm 
!
potentially surgery with neck dissection
In case a subject is diagnosed with medullary thyroid carcinoma, it is common clinical practice to 
explore the family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2 
and perform a genetic test for RET proto-oncogene mutation.
2.2
Calcitonin ≥ 50 and < 100 ng/L
Action: The subject should be referred to a thyroid specialist for further evaluation. The subject 
should remain in the trial and continuation on trial product should be based on the evaluation done 
by the thyroid specialist. 
Background: These values were found in 8 (0.14%) of the population of 5817 patients with thyroid 
nodular disease1. Two of these subjects were diagnosed with medullary thyroid carcinoma 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 there are no contraindication, 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

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 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 disease1. 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 al1 identified 216 (3.7%) patients. One patient 
out of the 216 had a subsequent basal (unstimulated) calcitonin 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 calcitonin > 10 and < 
20 ng/L to allow conclusions.2, 3

1.4.1
Assessments in case of suspicion of acute pancreatitis
Most patients with acute pancreatitis experience severe abdominal pain that is located generally in 
the epigastrium and radiates to the back. The onset of the pain may be swift reaching maximum 
intensity within 30 min, it is frequently unbearable and characteristically persists for more than 
24 hours without relief1. The pain is often associated with nausea and vomiting. Physical 
examination usually reveals severe upper abdominal tenderness at times associated with guarding.
In general, both amylase and lipase are elevated during the course of acute pancreatitis. The serum 
lipase may remain elevated slightly longer than amylase. The level of the serum amylase and/or 
lipase does not correlate with the severity of acute pancreatitis1. In general, serum lipase is thought 
to be more sensitive and specific than serum amylase in the diagnosis of acute pancreatitis.
In case of suspicion of acute pancreatitis, the trial product should promptly be interrupted (no 
treatment discontinuation call should be made in the interactive web response system (IWRS)
before diagnosis of acute pancreatitis is confirmed). Appropriate additional examinations must be 
performed, including local measurement of amylase and lipase.
The diagnosis of acute pancreatitis requires two of the following three features2:
!
abdominal pain consistent with acute pancreatitis (acute onset of a persistent, severe, epigastric 
pain often radiating to the back)
!
serum lipase activity (and/or amylase activity) at least three times greater than the upper limit of 
normal
!
characteristic findings of acute pancreatitis on imaging.
If acute pancreatitis is ruled out, trial product should be re-initiated.
If acute pancreatitis is confirmed, appropriate treatment and careful monitoring of the subject 
should be initiated. The subject must be discontinued from trial product (treatment discontinuation 
call), but should remain in the trial (see protocol Section 6.5 and 8.1.5).

1.8.1
Assessments in case of suspicion of hypersensitivity reaction
In case of suspicion of a severe immediate systemic hypersensitivity reaction3 to the trial product, 
the subject must be discontinued from trial product but should remain in the trial (see protocol 
Section 6.5 and 8.1.5).
If suspicion of a hypersensitivity reaction occurs, the subjects should be instructed to contact the 
site staff as soon as possible for further guidance.
To assist in the diagnostic evaluation it is recommended to draw a blood sample for measurement of 
tryptase (total and/or mature tryptase, local assessment) within 3 hours of onset of the 
hypersensitivity reaction, and if this is achieved, a tryptase sample should also be drawn at V14A.
Furthermore, a blood sample for assessment of anti-semaglutide IgE antibodies should be drawn as 
soon as possible after the event and at V14A and sent to central laboratory. Tryptase concentrations, 
if available, should be included in the specific event form when reporting the AE.
In case of suspicion of immune complex disease3, the subject must be discontinued from trial 
product but should remain in the trial (see protocol Section 6.5 and 8.1.5). It is recommended to 
draw a blood sample for local assessment of complement levels (C3 and C4) to assist in the 
diagnostic evaluation. Complement level results should be included in the specific event form when 
reporting the AE.

Introduction including rationale for the protocol amendment
This protocol amendment introduces:
1. Additional eye examinations and additional data collection on diabetic retinopathy 
2. Investigator’s responsibility in ensuring evaluation and management of certain risk factors and 
complications
3. Clarification of the criteria for completion, withdrawal and lost to follow-up
4. Alignment of rescue medication not allowed
5. Other minor corrections and clarifications
1.1
Additional eye examinations and additional data collection on diabetic retinopathy
Updated protocol Sections: 2, 4.2.2.2, 8.4.1.2, 8.4.4, 12.1.5, 17.4.2.2, 18.1 and Appendix B, section 
1, 1.14.
Transient worsening of diabetic retinopathy is a recognised complication in selected patients with 
diabetes after initiation of intensive antidiabetic treatment. Risk factors for these events include 
long-standing poor glycaemic control and presence of proliferative retinopathy, and initial large 
improvements in blood glucose may be an additional aggravating factor123. In a recently completed 
cardiovascular outcomes trial with s.c. semaglutide, results indicate an increased risk of events 
related to diabetic retinopathy in subjects treated with semaglutide compared to placebo4 . The 
majority of the related adverse events were moderate in severity and did not lead to premature 
discontinuation of trial product. 
, additional eye examinations 
have been implemented in all trials in the PIONEER program. Also, to further understand this  
safety signal, additional information will be collected  for all diabetic retinopathy events reported 
during the trial. The information will be collected not only from new subjects enrolled by the time 
of this amendment, but also from already enrolled subjects to the extent that the information is 
available. Furthermore, information to the investigators and subjects related to diabetic retinopathy 
has been added to the protocol (see Section 18) and the subject information.

1.2
Investigator’s responsibility in ensuring evaluation and management of certain risk 
factors and complications
Updated protocol Section: 8.4.2 and 18.1.
, text is added to highlight the investigator’s responsibility in 
relation to further evaluation of potential incidental thyroid nodules discovered at the physical 
examination.
In addition, text is added to highlight the investigator’s responsibility in ensuring evaluation and 
management of cardiovascular risk factors and microvascular complications such as diabetic kidney 
disease and diabetic retinopathy.
1.3
Clarification of the criteria for completion, withdrawal and lost to follow-up
Updated protocol Sections: 6.6, 8.1.4, 8.1.5 and 8.1.6.1.
The criteria for subject completion, -withdrawal and -lost to follow-up respectively are clarified and 
have been made consistent across sections. Lost to follow-up is considered a subcategory to 
withdrawal from trial. In addition, it is emphasised that as soon as contact to a subject is lost, efforts 
must be made to regain contact and the efforts must continue until the subjects last planned visit. 
Only if contact is not regained at that time point can the subject be considered lost to follow up. 
Because this trial is not an outcome trial the terminology ‘health status’ is replaced with “relevant 
safety information” - the purpose of which is to follow up on any adverse events or pregnancy, and 
not to determine if a subject completes the trial or not.
1.4
Alignment of rescue medication not allowed
Updated protocol Section: 18.1.1.
The section 181.1 of the protocol has been updated as there was a discrepancy between the rescue 
medication which is not allowed are listed in 6.4 and in section 18 in order to avoid any mistakes in 
the use of rescue medication. The products which are not allowed as rescue medication are;
GLP-RAs, DPP-4 inhibitors and amylin analogues. 
1.5
Other minor adjustments, clarifications and correction of typographical errors
1.5.1
Laboratory analysis
Updated protocol Sections: 8.4.8 
The protocol currently specifies that the in vitro neutralising antibody assays will be performed by 
Novo Nordisk, however, it may be decided by Novo Nordisk that the laboratory currently 
responsible for antibody binding analysis (Celerion) will perform the assay.

Adverse events for Adjudication
Updated protocol Section: 12.7.2
Table 12-2 has been aligned with Table 12-1 reflecting that unstable angina pectoris (UAP) requires 
hospitalisation to qualify for Event Adjudication.
1.5.3
Statistical considerations
Updated protocol Sections: 17.2, 17.3.1 and 17.4.2.1
The eye examination category has been added to the list of assessments where the follow-up period 
is included in the “on-treatment” observation period. This is due to the inclusion of the fundus 
photography or dilated fundoscopy at the end of trial visit or within 5 weeks thereafter for subjects 
completing treatment.
For the pattern mixture model using multiple imputations, the number of imputations will be 
increased from 100 to 1000 data sets, to ensure a greater precision of the estimates. In addition, an 
error in the number of groups used for imputation is corrected.

Withdrawal from trial
The subject may withdraw consent at will at any time. The subject’s request to withdraw from the 
trial must always be respected.  Only subjects who withdraw consent should be considered as 
withdrawn from trial.  A subject who does not complete the trial is also considered withdrawn from 
the trial. Hence a subject is considered withdrawn if the following applies: 
!
Subject withdrew consent 
!
Subject was lost to follow up (only to be used if there was no contact with the subject by the 
time of the subject’s last scheduled visit, see sections 8.1.4 -  8.1.6.1)

At V13 the subject should be reminded about the importance of attending the follow-up visit (V14). 
If the subject, nonetheless, does not attend V14, the site should make efforts to obtain contact with 
the subject within the visit window.

A trial completer is defined as a subject who attends, or is in contact with the site, at the subject’s 
last scheduled visit. For subjects who complete treatment, the last scheduled visit is V14. (For 
subjects who discontinue trial product, see section 8.1.5). 
In case the subject cannot be reached (by clinic visit or phone contact) at the scheduled V14, the site 
should consult the contacts provided by the subject (e.g. close relatives), relevant physicians, 
medical records and locator agencies (if allowed according to local law) to collect health status. If 
no health status can be collected, the subject should be considered lost to follow-up and this should 
be specified in the end-of-trial form.
2.5
Section 8.1.5 
Premature discontinuation of trial product and follow-up (visit 13A 
and visit 14A)
…
Subjects should continue with the originally scheduled site contacts after V14A and up to and 
including V13. If necessary, in order to retain the subject in the trial, site visits can be replaced by 
phone contacts after V14A. However, if a subject is unable or unwilling to attend all subsequent 
visit(s), the investigator should at least aim to have the subject attend V13 (end-of-treatment) as this 
visit should be performed for all subjects, if at all possible (except subjects who withdraw informed
consent, see Section 8.1.6).
Subjects, who only agree to attend or provide health status at the planned V13, should not be 
considered withdrawn from the trial. In case the subject cannot be reached (by clinic visit or phone 
contact) at the scheduled V13, the site should consult the contacts provided by the subject (e.g. 
close relatives), relevant physicians, medical records and locator agencies (if allowed according to 
local law) to collect health status. If no health status can be collected, the subject should be 
considered lost to follow-up and this should be specified in the end-of-trial form. 
A subject who prematurely discontinued trial product is still considered a trial completer if the 
subject attends or is in contact with the site, at the subject’s last scheduled visit. For subjects who 
prematurely discontinue trial product, the last scheduled visit is V13 (or V14A if it is scheduled 
after V13). The site should in due time prepare for establishing contact with the subject within the 
visit window of the scheduled V13, if the subject has agreed to attend this visit. 
In summary, subjects should stay in the trial irrespective of lack of adherence to randomised 
treatment, lack of adherence to visit schedule, missing assessments or trial product discontinuation 
for any reason. Only subjects who decline any further contact with the site in relation to the trial 
should be considered as having withdrawn consent from the trial (for withdrawal procedures see 
Section 8.1.6).

Lost to follow-up
In case contact to the subject is lost during the trial, the site should immediately undertake efforts to 
re-establish contact. If the subject cannot be reached (by clinic visit or phone contact) and the 
subject has consented to it, the site should consult the contacts provided by the subject (e.g. close 
relatives), relevant physicians, medical records and locator agencies (if allowed according to local 
law) in an attempt to regain contact with the subject or to obtain relevant safety information from 
other sources. Efforts to regain contact should continue until the end of the subject’s last scheduled 
visit: V14 for subjects who have completed treatment, whereas for subjects who have discontinued 
trial product prematurely the last visit is V13 (or V14A, if it is scheduled after V13). Only if contact 
with the subject is not regained by the end of the visit window of the last scheduled visit can the 
subject be considered lost to follow up (see Section 6.6).

An analysis of covariance (ANCOVA) with region, stratification factors and the interaction 
between the two stratification factors as categorical fixed effects and baseline HbA1c 
measurement as a covariate will be fitted to observed values of the change from baseline in 
HbA1c at week 26.
!
The estimated parameters for location and dispersion will be used to impute 100 1000 values 
for each subject with missing week 26 data based on region, stratification factors, the 
interaction between the two stratification factors and baseline HbA1c. Thus, 100 1000 
complete data sets will be generated including observed and imputed values.
Analysis used for confirming superiority versus placebo at week 26:
For each of the 100 1000 (now complete) imputed data sets, the change in HbA1c from baseline to 
week 26 will be analysed using an ANCOVA with treatment, stratification factors, the interaction 
between the two stratification factors and region as categorical fixed effects and baseline HbA1c as 
covariate. The results obtained from analysing the datasets will be combined using Rubin’s rule52 to 
draw inference.

The above eight binary endpoints will be analysed using a logistic regression model with treatment, 
stratification factors, the interaction between the two stratification factors and region as fixed 
effects and baseline response as covariate (i.e. baseline HbA1c for binary HbA1c endpoints, baseline 
weight for weight endpoints and both baseline HbA1c and baseline weight for the binary endpoints 
that combines both parameters). To account for missing data, the analysis will be made using a 
sequential multiple imputation approach as described below:
!
Multiple imputed data sets (100 1000) will be created in which missing values for the 
underlying continuous assessments are imputed by treatment group and treatment 
adherence/rescue status assuming MAR and as described in Section 17.3.1 for the primary 
estimand and by treatment group assuming MAR and as described in Section 17.3.2 for the 
secondary estimand.

Other safety considerations
Diabetic retinopathy complications
A transient worsening of diabetic retinopathy is a recognised complication in selected patients with 
diabetes after initiation of intensive antidiabetic treatment56,57,58. Risk factors for these events 
include long-standing poor glycaemic control and presence of proliferative retinopathy, and initial 
large improvements in blood glucose may be an additional aggravating factor. Several studies 
have, however, documented long-term beneficial effects of intensive glycaemic treatment in 
reducing retinopathy progression59,60 even in intensively treated patients who experienced early 
worsening57. In a cardiovascular outcomes trial with s.c. semaglutide, results indicate an increased 
risk of events related to diabetic retinopathy in subjects treated with semaglutide compared to 
placebo61. As a precaution in this trial, all subjects are required to have a fundus photography or 
dilated fundoscopy performed before enrolment into the trial; moreover, subjects with proliferative 
retinopathy or maculopathy requiring acute treatment will be excluded. As part of good diabetes 
management the investigator is encouraged to ensure adequate monitoring and treatment of 
diabetic retinopathy in subjects enrolled into the trial62. 
…
General precautions
…
There are also strict glyacemic rescue criteria in place to ensure acceptable glycaemic control 
during the trial. If rescue medication is required, it should be in accordance with ADA/European 
Association for the Study of Diabetes31.32 (excluding GLP-1 RAs, DPP-4 inhibitors, and amylin 
analogues and SGLT-2 inhibitors).

It is the responsibility of the investigator to ensure the best possible care of the subject. This 
includes adequate glycaemic control, appropriate risk factor modification such as optimal 
treatment of hypertension, dyslipidaemia and other cardiovascular risk factors, as well as regular 
monitoring and treatment of diabetic kidney disease and diabetic retinopathy according to the 
principles outlined in (Diabetes Care 2016 Standards of Medical Care in Diabetes)62.
