Summary
Objectives and endpoints:
Primary Objective
To compare the effects of three dose levels of once-daily oral semaglutide (3, 7 and 14 mg) versus 
once-daily placebo on glycaemic control in subjects with type 2 diabetes mellitus treated with diet 
and exercise only.
Secondary Objectives
To compare the effects of three dose levels of once-daily oral semaglutide (3, 7 and 14 mg) versus 
once-daily placebo on body weight in subjects with type 2 diabetes mellitus treated with diet and 
exercise only.
To compare the safety and tolerability of three dose levels of once-daily oral semaglutide (3, 7 and 
14 mg) versus once-daily placebo in subjects with type 2 diabetes mellitus treated with diet and 
exercise only. 
Primary endpoint
Change from baseline to week 26 in HbA1c.
Key secondary endpoints
Change from baseline to week 26 in:
!
Body weight (kg)
!
Fasting plasma glucose
If a subject after week 26 achieve (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-blinded, placebo-controlled, four-armed, parallel-group, 
multi-centre, multi-national trial comparing the efficacy and safety of three dose levels of once-
daily oral semaglutide and placebo in subjects with type 2 diabetes mellitus treated with diet and 
exercise only.

Background information and rationale for the trial
The trial will be conducted in compliance with this protocol, International Conference on 
Harmonisation (ICH) Good Clinical Practice (GCP)1 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.
For Mexico only: the above will include the following responsibilities for the head of the 
Institution/Health Care Establishment, Ethics, Research and, when applicable, Biosafety 
Committees and sponsor within their scope of responsibility: a) Investigation follow-up b) Damages 
to health arising from the investigation development; as well as those arising from interruption or 
advanced suspension of treatment due to non-attributable reasons to the Subject; c) Timely 
compliance of the terms in which the authorization of a research for health in human beings had 
been issued; d) To present in a timely manner the information required by the Health Authority.
3.1
Background information
For an assessment of benefits and risks of the trial, see Section 18.1.
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 (BG) 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 GLP-1 receptor agonists (GLP-1 
RA) 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), 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 where to 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
Non-clinical data
3.1.4.1
Semaglutide
The non-clinical programme for semaglutide was designed according to the ICH M3 guideline21 to 
support the clinical development. The standard non-clinical 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 monkeys, 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 non-clinical studies can be found in the investigator’s brochure (IB)
for semaglutide (subcutaneous administration), edition 1023 and the IB 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 
non-clinical 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.
 
 
 
 
 
Measurements of lactate levels have been 
included at selected time points around peak concentrations of SNAC in two of the phase 3a trials

in the PIONEER programme (NN9924-4223 and this trial) with the intention to document that 
SNAC does not impair cellular respiration in humans. In addition, events of lactic acidosis must be 
reported as an adverse event (AE) requiring additional data collection, please refer to section 
8.4.1.2, section 12.1.5 and appendix B.
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 non-clinical studies can be found in the IB 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 IB 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 subcutaneous (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.

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. 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 adverse events (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.
For further details, please see the IB for oral administration of semaglutide (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. 
The aim of this 26-week, confirmatory phase 3a trial is to demonstrate superiority with three doses 
of oral semaglutide versus placebo on HbA1c and body weight in T2DM subjects treated with diet 
and exercise only, and to evaluate the efficacy and safety of oral semaglutide in a monotherapy 
setting.

Trial design
5.1
Type of trial
This is a 26-week, randomised, double-blinded, placebo-controlled, four-armed, parallel-group, 
multi-centre, multi-national trial comparing the efficacy and safety of three dose levels of once-
daily oral semaglutide and placebo in subjects with T2DM treated with diet and exercise only.
Subjects will be randomised 1:1:1:1 to receive one of the following treatments:
!
3 mg oral semaglutide once daily
!
7 mg oral semaglutide once daily 
!
14 mg oral semaglutide once daily 
!
Placebo once daily
The randomisation will be stratified based on descent (Japanese subjects/non-Japanese subjects). 
The total trial duration for the individual subject will be approximately 33 weeks, including a 2-
week screening period followed by a 26-week randomised treatment period and a 5-week follow-up 
period. The trial design is illustrated in Figure 5–1.
Figure 5–1
Trial design
5.2
Rationale for trial design
The trial has been designed as a parallel-group, 4-armed superiority trial to compare three doses of 
oral semaglutide with placebo in a monotherapy setting. Subjects will be randomised and the trial 
will be double blinded. 
There will be strict rescue criteria in place to ensure acceptable glycaemic control during the trial 
for all treatment arms, including the placebo arm (see Section 6.4).

The treatment duration of 26 weeks is considered adequate to evaluate the efficacy of semaglutide 
versus placebo, and furthermore, for the assessment of safety and tolerability. 
The follow-up period is 5 weeks to allow for wash-out of semaglutide and to prevent interference in 
the antibody assay.
5.3
Treatment of subjects
Subjects will be randomised to oral semaglutide or placebo. Subjects randomised to oral 
semaglutide will initiate treatment with 3 mg once daily. Subjects randomised to a treatment dose of 
7 or 14 mg, will follow a fixed 4-week dose-escalation regimen until reaching the maximum 
randomised dose, as illustrated in Table 5–1. All dose levels, including the dose-escalation, will be 
blinded. To mitigate the risk of gastrointestinal AEs, it is important to follow the fixed 4-week dose 
escalation intervals.

Dosing instructions
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. Trial product can be taken with up to half a glass of water (approximately 120 
mL/4 fluid oz). The tablet 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
As the present trial is a monotherapy trial no anti-diabetic medications are allowed 90 days before 
visit 1 and during the trial. Please see Section 6.4 with regards to rescue medication.

5.4
Treatment after discontinuation of trial product
When discontinuing trial products, either at the scheduled end-of-treatment visit (see Section 8.1.4)
or if trial product is discontinued prematurely (see Section 8.1.5), the subject should be switched to 
a suitable marketed product at the discretion of the investigator. After discontinuation of 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. 
Oral semaglutide will not be available for prescription until after marketing authorisation.
5.5
Rationale for treatment
For oral semaglutide, the three dose levels (3, 7 and 14 mg), treatment initiation with the lowest 
dose and 4-week dose escalation step have been chosen based on the data from the phase 2 dose-
finding trial NN9924-3790. The regimen is expected to have the optimal benefit risk profile for 
further development for treatment of T2DM in the PIONEER programme.
Subjects randomised to 14 mg oral semaglutide will be dose escalated to the highest dose level to 
investigate and establish maximum efficacy and safety in subjects in a monotherapy setting. 
The duration of randomised treatments is considered adequate to collect sufficient data on efficacy 
and safety in accordance with the trial objectives.

6.4
Rescue criteria
Subjects with persistent and unacceptable hyperglycaemia should be offered treatment 
intensification. To allow time for dose escalation and to observe the expected effect of treatment on 
glycaemic parameters, rescue criteria will be applied from week 8 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 (at the central laboratory) should be obtained 
by calling the subject for a re-test. If the confirmatory FPG also exceeds the values described below, 
the subject should be offered rescue medication (i.e. initiation of anti-diabetic medication):
!
13.3 mmol/L (240 mg/dL) from week 8 to the end of week 13
!
11.1 mmol/L (200 mg/dL) from week 14 to the end-of-treatment
It is important for the integrity of the trial that only subjects actually needing treatment 
intensification (as defined above) are started on rescue medication. Subjects who are started on 
rescue medication should continue to follow the protocol-specified visit schedule. Rescue 
medication should be prescribed at investigator’s discretion as add-on to randomised treatment and 
according to ADA/European Association for the Study of Diabetes guidelines25, 26 (excluding GLP-
RAs, DPP-4 inhibitors and amylin analogues).  
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.

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:
!
Safety concern related to the trial product or unacceptable intolerability
!
Included in the trial in violation of the inclusion and/or exclusion criteria
!
Pregnancy
!
Intention of becoming pregnant
!
Simultaneous participation in another clinical trial of an approved or non-approved 
investigational medicinal product (IMP)
!
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 
withdrawn from trial.
See Section 8.1.6 for procedures to be performed for subjects withdrawing consent. 
For Mexico only: should the subject, his/her family members, parents or legal representative decide 
to withdraw the consent for participation in the trial, the subject will be entitled to receive 
appropriate, free of charge medical care and/or trial drug during the follow-up period of the 
protocol when it will be established with certainty that no untoward medical consequences of the 
subject´s participation in the research occurred.

6.8
Rationale for trial population
The trial population will include subjects with T2DM treated with only diet and exercise for at least 
30 days prior to screening in order to evaluate the efficacy and safety of oral semaglutide in a 
monotherapy setting. Furthermore, no anti-diabetic medication are allowed at least 90 days prior to 
screening as changes in background treatment shortly before trial participation may potentially 
impact the data interpretation. The upper HbA1c limit of 9.5% (80 mmol/mol) has been chosen as 
this is a placebo-controlled trial. FPG will be monitored throughout the trial and rescue medication 
should be initiated in subjects with persistent, unacceptable hyperglycaemia. Subjects with liver test 
abnormalities (ALT > 2.5 x UNL) will be excluded to avoid potential confounding of liver safety 
assessments. Overall, the eligibility criteria will allow for enrolment of a relatively broad trial 
population resembling the target population in common clinical 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. It is the responsibility of the investigator 
to ensure that all visits occur according to the flow chart.
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 telephone 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 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. 
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.
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 visit 1 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 
misplaced), 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 and injectable medications can be 
administered after blood sampling. Exceptions are visits were samples for SNAC PK and lactate are 
taken. At these visits, other oral medication must be taken after last blood samples are taken. Note 
that for all subjects, the required fasting period is longer at visits with PK sampling and lactate 
assessments (see Section 8.6).
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 fasting blood samples
done within the visit window for the relevant visit.
Fasting samples:

Randomisation and trial product administration
Eligible subjects will be randomised into one of 4 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. It is important to dispense the exact allocated DUNs to the subject. 
When DUNs are dispensed, please confirm the dispensed date in the IWRS.
All visit 2 assessments must be performed before administration of first dose of trial product.

Trial products (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 dosing instruction visit, please see Section 2 and 5.3.1.
Date of first administration of trial product will be captured in the eCRF.
8.1.4
End-of-treatment (visit 8) and Follow-up (visit 9)
Subjects, who stay on trial product throughout the trial, must attend the end-of-treatment visit (V8) 
26 weeks after randomisation (±3 days visit window) and the Follow-up visit (V9) 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 visit 8 (see Section 10).
In case the subject cannot be reached (by site visit or phone contact) at the scheduled visit 9, 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 (visits 8A and 9A)
Subjects, who discontinue trial product prematurely, should attend visit 8A, scheduled to take place 
on the day of discontinuation of trial product (+ 3 days visit window). Visit 9A 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 visit 8A (see Section 10).
If premature discontinuation of trial product is decided during a scheduled visit, the visit will be 
converted into a V8A and trial procedures must be performed accordingly.
Subjects should continue with the originally scheduled site contacts after visit 9A and up to and 
including visit 8. After visit 9A, samples for antibodies, PK and lactate assessment should not be 
taken. If necessary, in order to retain the subject in the trial, site visits can be replaced by phone 
contacts after visit 9A. However, as a minimum, these subjects should be asked to attend the 
scheduled end-of-treatment visit (V8) at week 26 as these visits 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 scheduled V8, should not be 
considered withdrawn from the trial. In case the subject cannot be reached (by site visit or phone 
contact) at the scheduled V8, 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

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.
8.1.6
Withdrawal from trial
If a subject considers withdrawing from the trial, the investigator must aim to undertake procedures 
for visit 8A as soon as possible and visit 9A should be scheduled 5 weeks (+3 days visit window) 
after the last date on trial product, if the subject agrees to it.
Subjects who agree to attend or provide health status at the planned V8 should not be considered 
withdrawn from the trial.
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.
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.

chronic gastritis)
Any change to a concomitant illness should be recorded during the trial. A clinically significant 
worsening of a concomitant illness must be reported as an AE (see Section 12).
It must be possible to verify the subject’s medical history and a valid fundus photography/dilated 
fundoscopy if previous assessment is used in source documents such as subject’s medical record. If 
a subject is not from the investigators own practice, the investigator must make reasonable effort to 
obtain a copy of subject’s medical record from relevant party e.g. primary physician. The 
investigator must document any attempt to obtain external medical information by noting the 
date(s) when information was requested and who has been contacted.

Self-measured plasma glucose (SMPG)
At visit 1, subjects will be provided with a BG meter including auxiliaries as well as instructions for 
use. The subjects will be instructed in how to use the device, and the instruction will be repeated as 
necessary during the trial. In case a hypoglycaemic episode is suspected, the provided BG meter 
should be used for SMPG measurement.
The BG 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 BG meters provided by Novo Nordisk should be used for the 
measurements required in the protocol.
For Japan only: The trial sites are allowed to purchase and supply themselves with BG meters, if 
possible. BG meters must be the same model as supplied by Novo Nordisk.
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 BG meter and 
correct reporting of these in the diary is advised in order to ensure adequacy of the data reported in 
the trial database. 
The subject will be instructed to perform a 7-point SMPG profile two times during the trial period 
(see Section 2) using the BG meter provided for the trial. The 7-point SMPG profile should be 
performed on a day where the subject does not anticipate unusual strenuous exercise. The 7-point 
profile should preferably be taken within a week prior to the visit.
The record of each SMPG measurement should include the following seven time points:
!
Before breakfast
!
90 minutes after start of breakfast
!
Before lunch
!
90 minutes after start of lunch
!
Before dinner

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 
inch 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
PRO will be assessed using the questionnaires:
!
SF-36v2™ (acute version) health survey32-34
!
IWQOL-Lite Clinical Trial Version35, 36
!
PGI-S items
!
PGI-C items
The questionnaires SF-36v2™ and IWQOL-Lite Clinical Trial Version are commonly used 
instruments to evaluate the PROs, also in the T2DM area. The PGI-S items are designed to assess 
patients’ impression of their health status and the PGI-C items are designed to assess patients’ 
impression of change of their health. 
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 fifteen 
minutes to complete the four questionnaires. Subjects should be given the opportunity to complete 
the questionnaires by themselves without interruption. The completed questionnaires must be 
reviewed for potential adverse events 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.
SF-36 acute version
SF-36v2™ acute version 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. SF-36v2™ contains 36 items.
Impact of Weight on Quality of Life Clinical Trial Version
The IWQOL-Lite for Clinical Trials was adapted from the IWQOL-Lite and measures the health-
related quality of life. The IQWOL-Lite Clinical Trial Version contains 22 items.
Patients Global Impression of Status Items
The PGI-S assesses patients’ impression of physical functioning and mental health status during the 
clinical trial. The PGI-S contains two items.
Patients Global Impression of Change items
The PGI-C assesses patients’ impression of change in physical functioning and mental health during 
the clinical trial compared to when they entered the trial. Hence, the PGI-C should not be answered 
at V2. The PGI-C contains two items.

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 (MI), 
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 MI, 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 in 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 MI detected by the central ECG reading will be adjudicated by the 
Event Adjudication Committee (EAC) (see Section 12.7.2).

Anti-semaglutide antibodies
Blood samples will be drawn for measurement of serum antibodies against semaglutide at selected 
visits (see Section 2). Positive anti-semaglutide binding antibody samples will be further 
characterised for cross reactivity to native GLP-1. Samples which are positive for anti-semaglutide 
binding 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. 
Antibody samples will be stored as described in Section 24.2.

Hypoglycaemic episodes
Plasma glucose (PG) should always be measured and recorded when a hypoglycaemic episode is 
suspected.
All PG 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 visit 1 
to end of trial.
Upon onset of a hypoglycaemic episode the subject is recommended to measure PG 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 guidelines38.
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 PG 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 PG 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 PG
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 experience 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 date, time and dose of other anti-
diabetic medication prior to the episode.
!
Date and time of last main meal (not including snacks) prior to the episode.
!
Whether the episode occurred in relation to physical activity.
!
Change in any concomitant illness.
!
Any sign of fever and/or other acute disease.
!
Whether the subject was asleep when the episode occurred.
–
If yes, whether the symptoms of the episode woke up the subject.
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. PG concentrations may not be available during an event, but 
neurological recovery following the return of PG to normal is considered sufficient evidence that 
the event was induced by a low PG concentration38.
Oral carbohydrates must not be given if the subject is unconscious.

Did the subject experience any of the following symptoms39
–
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 (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 data 40, 41.
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 (SIF) 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 (semaglutide and SNAC) will be analysed by a special laboratory and Novo

Nordisk A/S (see Sections 8.4.8 and 8.6.2). 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).
For Mexico only: Descriptions of assay methods, laboratory supplies and procedures for obtaining 
samples, handling, transportation and storage of biological samples and information regarding 
who will perform the assessments, will be described in a trial specific laboratory manual, provided 
by the central laboratory (for central laboratory details, see attachment 1). 
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.
The central laboratory will provide laboratory results to the investigator on an on-going basis. 
However, anti-semaglutide antibody, 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. 
8.5.1
Fasting plasma glucose
FPG is measured at central laboratory in order to evaluate glycaemic control. The subject must 
attend these visits fasting (see Section 8.1.2).
A central FPG result ≤3.9 mmol/L (70 mg/dL) in relation to planned fasting visits should not be 
reported as a hypoglycaemic episode but as a clinical laboratory adverse event (CLAE) at the 
discretion of the investigator (see Section 12.1.1).

Other assessments
8.6.1
Lactate
Assessment of lactate levels will be included in this trial as a biomarker for impaired cellular 
respiration (see Section 18). At selected visits (see flow chart, Section 2) three samples should be 
drawn for lactate assessment at the following time points in relation to dosing of trial product:
!
Pre-dose
!
25 (+/- 5) minutes post-dosing
!
40 (+/- 5) minutes post-dosing
At visits with lactate sampling trial product must be taken at site. The subject must be fasting and 
not take any other oral medication until last sample has been taken, that is, at least 40 minutes after 
dosing (see Section 8.1.2 in case the subject attends the visit in a non-fasting state). Also, the 
subject should have rested for at least 30 minutes in a sitting position prior to sampling. During 
sampling, use of tourniquet should be avoided (if possible) and if blood pressure measurement has 
been performed prior to sampling, blood should preferably be drawn from the opposite arm.
Correct pre-analytical handling of these samples is extremely important to ensure valid results. The 
blood samples must be kept on ice and centrifuged within 15 minutes of collection. Further 
handling and transportation of the samples are described in the laboratory manual.
The date and exact time of dosing of trial product must be recorded in the medical record and 
entered into the eCRF. The date and exact time of sampling must be recorded at the laboratory 
requisition form.
8.6.2
Pharmacokinetics
Blood samples for the semaglutide and SNAC PK will be drawn at selected visits (see flow chart, 
Section 2) and must be collected, handled and shipped according to the description in the laboratory 
manual. 
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.

SNAC PK sampling
Samples for SNAC PK should be drawn at the following time points in relation to dosing of trial 
product:
!
25 (+/- 5) minutes post-dosing
!
40 (+/- 5) minutes post-dosing
At visits with sampling of SNAC PK trial product must be taken at site. The subject must be fasting 
and not take any other oral medication until last sample has been taken (see section 8.1.2 in case the 
subject attends the visit in a non-fasting state).
The date and exact time of dosing of trial product must be recorded in the medical record and

requisition form.
8.6.2.2
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 at the laboratory requisition form.

8.7
Subject compliance
Throughout the trial, the investigator will remind the subjects to follow the trial procedures and 
requirements to ensure subject compliance.
Treatment compliance: will be assessed by monitoring of drug accountability. Prior to visits 
where drug accountability is performed, the subject will be asked to return all used, partly used and 
unused trial products and dosepacks. The investigator must assess the amount of trial products 
returned compared 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.

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. The randomisation will be stratified based on descent (Japanese subjects/non-Japanese 
subjects) to ensure an even distribution of the four treatment arms (see Section 17).
At the randomisation visit (V2) subjects meeting all eligibility criteria will be randomised to one of 
four parallel treatment arms as described in Section 5.1.
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 the IWRS.
The laboratory responsible for antibody and PK (semaglutide and SNAC) 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 adverse event (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 clinical laboratory adverse event (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 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 adverse events 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). 
12.1.3
Non-serious adverse event
A non-serious AE is any AE which does not fulfil the definition of an SAE.
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,
12.1.5 and appendix B.

12.1.6
Technical complaints
A technical complaint is any written, electronic, or oral communication that alleges product 
(medicine) defects. The technical complaint may be associated with an AE, but does not concern 
the AE itself.
Examples of technical complaints:
!
The physical or chemical appearance of trial products (e.g. discoloration, particles or 
contamination)
!
All packaging material including labelling
Only technical complaints related to adverse events 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 
occurring from the first trial-related activity after the subject has signed the informed consent until 
the end of the post-treatment follow-up period (V9) for subjects on trial product, or until the end of 
trial (V8 or V9A, 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 SIF must be completed in addition to the AE form. A SIF is a form to collect 
supplementary clinical information. If several symptoms or diagnoses occur as part of the same 
clinical picture, one SIF 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 event adjudication committee (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 SIF 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 investigators first knowledge of the 
AE.
!
Events for adjudication: adjudication form should be completed within 14 calendar days 
of 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 adverse events
Novo Nordisk assessment of AE expectedness: 
Novo Nordisk assessment of expectedness is performed according to the following reference 
documents: IB for oral administration of 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 (EMA), 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 
SIF. 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 on-going 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 
on-going 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 
ended the trial, the investigator should report this SAE within the same timelines as for SAEs 
during the trial.

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.

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.
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), 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.

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 SIF.
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 
 day and was thus treated with 20 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. 
 and the subject 
wished to continue in the trial. No symptoms of hypoglycaemia or any other symptoms or signs 
were noted.

Committees related to safety
12.7.1
Novo Nordisk safety committee
Novo Nordisk will constitute an internal oral semaglutide safety committee to perform on-going 
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 source 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 FDA requirements43.
The EAC will review copies in English (translated if necessary) of medical documentation received 
in the adjudication packages (e.g. x-ray, ECGs, ultrasound images, discharge summaries, pathology 
reports and death certificates). The investigator must provide medical documentation as soon as 
possible, when they receive the request from Novo Nordisk or the event adjudication vendor. The 
AEs for adjudication are listed in Table 12–2:

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.
The assessments made by the EAC will be included in the clinical trial report as well as assessments 
made by the investigator. However, the adjudication made by an EAC, given its independent 
analysis of each event, will be attributed with greater importance of the two. The outcome of 
adjudication will be kept in the clinical trial database.
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 case report forms (CRF):
!
Pregnancy forms
The following will be provided as paper CRFs to be used when access to the eCRF is revoked of if 
the eCRF is unavailable:
!
AE forms 
!
SIFs
!
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.
13.2
Case report form flow 
The investigator must ensure that data is recorded in the eCRF as soon as possible, preferably 
within 5 days after the visit. Once data has been entered, it will be available to Novo Nordisk for 
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 and 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 diaries and/or PROs must not be removed from the trial site, unless they form part of 
the CRF 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.
A follow-up letter (paper or electronic) will be sent to the investigator following each monitoring 
visit. This should address any action to be taken.
15 Data management
Data management is the responsibility of Novo Nordisk. Data management may be delegated under 
an agreement of transfer of responsibilities to another data management unit within Novo Nordisk 
or an external 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.

16 Computerised systems
Novo Nordisk will capture and process clinical data using computerised systems that are described 
in Novo Nordisk Standard Operating Procedures and IT architecture documentation. The use and 
control of these systems are documented.
Investigators working on the trial may use their own electronic systems to capture source data.
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.
The randomisation is stratified based on descent (Japanese subjects/non-Japanese subjects). The 
information regarding descent will be included based on country details from the IWRS. Descent
(Japanese subjects/non-Japanese subjects) will be included in the statistical analyses as part of 
region.
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 the below three comparisons with associated two-sided 95% confidence intervals and 
p-values corresponding to two-sided tests of no difference:
!
Oral semaglutide 14 mg vs. placebo
!
Oral semaglutide 7 mg vs. placebo
!
Oral semaglutide 3 mg vs. placebo
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 treatment adherence 
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, 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 and in the oral semaglutide 3 mg arm than for 
the two highest dose levels of oral semaglutide. A higher proportion of subjects are expected to 
discontinue treatment due to AEs in the oral semaglutide 14 mg arm, compared to the other 
treatment arms. 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.
17.1
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 at each dose level (3 mg, 7 mg, and 14 mg).
The sample size calculation is made to ensure a power of at least 90% to jointly confirm HbA1c
superiority of oral semaglutide vs. placebo at each dose level out of the six pre-specified 
confirmatory hypotheses shown in Figure 17–1. The closed testing procedure described in Bretz et 
al.45 is used to control the overall type I error at a nominal two-sided 5% level. The statistical testing 
strategy is built on the following two principles:
!
Within a dose level, glycaemic effect must be established in terms of HbA1c superiority 
before testing for added benefits in terms of body weight superiority.
!
Glycaemic effect in terms of HbA1c superiority must be established on all higher dose levels 
before continuing testing hypotheses on lower dose levels.
The sample size is calculated using the calcPower function in the R package, gMCP46 using 10000 
simulations. All of the six 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 common 
standard deviations used across dose levels are given in Table 17–1. These are primarily based on 
the oral semaglutide phase 2 results (NN9924-3790) and supported by results from the s.c. 
semaglutide phase 2 trial (NN9535-1821).
Since the equalising effect of rescue medication will be included in the primary analysis as well as 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 a 75%

Full analysis set (FAS): Includes all randomised subjects. Subjects in the FAS will contribute to 
the evaluation “as randomised”.
Safety analysis set (SAS): Includes all subjects exposed to at least one dose of trial product. 
Subjects in the SAS will contribute to the evaluation based on the trial product received for the 
majority of the period where they were on treatment. This will be referred to as contributing to the 
evaluation “as treated”.
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 (V9) for subjects on trial product
!
The latest occurring visit of the end-of-treatment visit (V8) or the follow-up premature 
discontinuation visit (V9A), 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 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 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 a 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 (V9)
!
The follow-up prematurely discontinuation visit (V9A)
!
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 end date is 
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 for 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 should 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 confirmatory secondary body weight endpoint the 
following confirmatory one-sided hypotheses are planned to be tested at each dose level of oral 
semaglutide versus placebo. Let the mean treatment difference be defined as μ = (oral semaglutide 
minus placebo):

Body weight superiority

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 six confirmatory hypotheses related to the HbA1c and body weight 
endpoints will be preserved in the strong sense at 5% (two-sided) using the weighted Bonferroni-
based closed testing procedure described in Bretz et al.45 and outlined in Figure 17–1.
The first hypothesis to be tested is superiority of HbA1c at the highest dose level. It will be tested at 
the overall significance level (5%) while allocating 0% local significance level to the remaining of 
the hypotheses. For this hypothesis, and in general, if a hypothesis is confirmed, then the 
significance level will be reallocated according to the weight and the direction of the edges going 
from the confirmed hypothesis to the next hypotheses as specified in Figure 17–1. Each of the 
following hypotheses will be tested at their updated local significance level (α-local). This process 
will be repeated until no further hypotheses can be confirmed.
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 its local two-sided significance level as defined by the closed 
testing procedure in Figure 17–1. This is equivalent to using a one-sided p-value (nominal α = 
0.025) and a one-sided 2.5% overall significance level in the closed testing procedure.
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 8 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 as a categorical fixed effect 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 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 from baseline to week 26 in 
HbA1c will be analysed using an ANCOVA with treatment and region as categorical fixed effects 
and baseline HbA1c as covariate. The results obtained from analysing the datasets will be combined 
using Rubin’s rule47 to draw inference.
From this analysis the estimated treatment differences between each of the oral semaglutide dose 
levels and placebo together with associated two-sided 95% confidence intervals and unadjusted 
two-sided p-values for testing no difference from zero will be presented.
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 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 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 EMA recommendations48
and with a report from the US National Research Council49, 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 for the primary analysis 
will be described that is not based on the pattern mixture model approach, see Section 17.3.3.2.
Sensitivity analyses for the primary estimand
The estimation of the primary estimand will be repeated using the following sensitivity analyses:
!
A comparator multiple imputation analysis based on FAS using the in-trial observation
period
!
A comparator multiple imputation analysis differentiating between reasons for discontinuing 
treatment prematurely based on FAS using the in-trial observation period
!

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:

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 AEs 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.
!
Tipping-point multiple imputation analysis: In this sensitivity analysis, missing data will 
first be imputed according to the primary analysis. Secondly, for all oral semaglutide 
treatment arms a penalty will be added to the imputed values at week 26. The approach is to 
gradually increase this penalty until all confirmed HbA1c conclusions from the primary 
analysis are changed. For each hypothesis tested the specific value of the penalty that 
reverses the conclusion will be used to evaluate the robustness of the primary analysis 
results. 
17.3.3.2
Other sensitivity analyses
The following additional sensitivity analysis will be specified:
!
Last observation carried forward 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 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. 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 local two-sided significance level resulting from the closed testing procedure in

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 8 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 reduction ≥ 1 %-point (10.9 mmol/mol)
!
Body weight loss ≥ 3 %
!
Body weight loss ≥ 5 %
!
Body weight loss ≥ 10 %
!
HbA1c < 7.0 % (53 mmol/mol) without hypoglycaemia (treatment-emergent severe or BG-
confirmed symptomatic hypoglycaemic episodes) 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.
!
The binary endpoint will be created for each of the 100 complete data sets
!
Each of the created complete data set will be analysed with the logistic model and inference 
will be drawn using Rubin’s rule47.

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 
treatment at the end-of-treatment visit and therefore might need addition of glucose-lowering 
medication during the follow-up period.
The endpoint will be described and compared for oral semaglutide versus placebo using likelihood 
ratio tests obtained from a Cox proportional hazards model with treatment, stratification factors, the 
interaction between the two stratification factors and region as categorical fixed effects and baseline 
HbA1c as a covariate. From this analysis the estimated Hazard ratios between oral semaglutide 
versus placebo will be presented together with 95% confidence intervals and two sided p values for 
test of no difference.

Safety endpoints
The safety endpoints will be evaluated based on SAS using the on-treatment observation period and 
based on SAS using the in-trial observation period unless otherwise stated. The following endpoints 
are used to support the safety objectives.
Adverse events 
!
Number of TEAEs during exposure to trial product, assessed up to approximately 31 weeks
All AEs will be coded using the most recent version of the Medical Dictionary for Regulatory 
Activities (MedDRA) coding. 
A treatment-emergent AE is defined as an AE with onset in the on-treatment observation period 
(see definition of 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 
summaries of AEs will be made for the in-trial observation period. The development over time in 
gastrointestinal AEs will be presented graphically.

episodes during exposure to trial product, assessed up to approximately 31 weeks
!
Treatment-emergent severe or BG-confirmed symptomatic hypoglycaemic episodes during 
exposure to trial product, assessed up to approximately 31 weeks (yes/no)
Classification of hypoglycaemia
Hypoglycaemic episodes will be summarised for the SAS and the on-treatment observation period 
only.
Treatment-emergent: hypoglycaemic episodes will be defined as treatment-emergent if the onset of 
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 PG level of 3.1 mmol/L 
(56 mg/dL)50. Therefore, Novo Nordisk has included hypoglycaemia with PG levels below this cut-
off point in the definition of 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 classification38 or BG-confirmed by a PG value < 3.1 mmol/L (56 mg/dL) with
symptoms consistent with hypoglycaemia.
ADA classification38 of hypoglycaemia
!
Severe hypoglycaemia: An episode requiring assistance of another person to actively 
administer carbohydrate, glucagon, or take other corrective actions. PG concentrations may 
not be available during an event, but neurological recovery following the return of PG to 
normal is considered sufficient evidence that the event was induced by a low PG
concentration.
!
Asymptomatic hypoglycaemia: An episode not accompanied by typical symptoms of 
hypoglycaemia, but with a measured PG concentration ≤ 3.9 mmol/L (70 mg/dL).
!
Documented symptomatic hypoglycaemia: An episode during which typical symptoms of 
hypoglycaemia are accompanied by a measured PG concentration ≤ 3.9 mmol/L 
(70 mg/dL).

Pharmacokinetic and/or pharmacodynamic modelling
Data from this trial will be evaluated using population pharmacokinetic analysis and exposure-
response for semaglutide. The purpose of the population pharmacokinetic analysis will be: 
!
To describe the covariate factors (such as weight, age, gender, race and ethnicity) that 
influence semaglutide exposure
!
To estimate a steady-state exposure level for each subject with pharmacokinetic data, in 
order to facilitate subsequent exposure-response analyses
The purpose of the exposure-response analyses will be to support the recommended dose, by 
investigating response and potentially side effects across the exposure range. 
The population pharmacokinetic and exposure-response analyses will be conducted as a meta-
analysis, including all relevant oral semaglutide phase 3a trials with PK assessments. A separate 
modelling analysis plan will be prepared before first database lock in the oral semaglutide phase 3a 
programme, outlining details of the analyses. The modelling will be performed by Quantitative 
Clinical Pharmacology at Novo Nordisk A/S and will be reported separately from the clinical trial 
report.

18.1
Benefit-risk assessment of the trial
Risks and precautions
The non-clinical 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 non-clinical 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 MEN 2 or MTC 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 non-clinical 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 EMA.
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 
sulphonylurea or insulin. The risk for development of hypoglycaemia with oral semaglutide in 
combination with sulphonylurea 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.
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 glycaemic 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 Diabetes 25, 26 (excluding GLP-1 RAs, DPP-4 inhibitors and amylin 
analogues).
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 Diabetes51.
Further details with regards to safety of trial product are described in the current edition of the IB 
for oral administration of semaglutide (NN9924)24, or any updates thereto.
18.1.1
Benefits 
In this trial, subjects in the semaglutide arms will be treated with a regimen anticipated to be a 
beneficial and efficient supplement to the treatment they receive at the time of entry into the trial 
being diet and exercise. 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 T2DM. 
In addition, it is expected that all subjects including those randomised to placebo will benefit from 
participation through close contact with the study 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.
All subjects in this trial will receive trial products and auxiliary supplies free of charge.

18.1.2
Risk and benefit conclusion 
The safety profile for the investigational medicinal product generated from the clinical and non-
clinical development programme has not revealed any safety issues that would prohibit 
administration of oral semaglutide in accordance with the planned clinical trial.  
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 requirement(s) 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.

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 
visit 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.

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).
20 Audits and inspections
Any aspect of the clinical trial may be subject to audits conducted by Novo Nordisk or inspections 
from domestic or foreign regulatory authorities or from IRBs/IECs. Audits and inspections may 
take place during or after the trial. The investigator and the site staff as well as Novo Nordisk staff 
have an obligation to cooperate and assist in audits and inspections. This includes giving auditors 
and inspectors direct access to all source documents and other documents at the trial site relevant to 
the clinical trial. This includes permission to examine, analyse, verify and reproduce any record(s)

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).

23 Reports and publications
The information obtained during the conduct of this trial is considered confidential and may be used 
by or on behalf of Novo Nordisk for regulatory purposes as well as for the general development of 
the trial product. All information supplied by Novo Nordisk in connection with this trial shall 
remain the sole property of Novo Nordisk and is to be considered confidential information.
No confidential information shall be disclosed to others without prior written consent from Novo 
Nordisk. Such information shall not be used except in the performance of this trial. The information 
obtained during this trial may be made available to other physicians who are conducting other 
clinical trials with the trial product, if deemed necessary by Novo Nordisk. Provided that certain 
conditions are fulfilled, Novo Nordisk may grant access to information obtained during this trial to 
researchers who require access for research projects studying the same disease and/or trial product 
studied in this trial.
Novo Nordisk may publish on its clinical trials website a redacted clinical trial report for this trial.
Two investigators will be appointed by Novo Nordisk to review and sign the clinical trial report 
(signatory investigator) on behalf of all participating investigators. The signatory investigators will 
be appointed based upon the criteria defined by the International Committee of Medical Journal 
Editors for research publications52.
23.1
Communication of results
Novo Nordisk commits to communicating and otherwise making available for public disclosure, 
results of trials regardless of outcome. Public disclosure includes publication of a paper in a 
scientific journal, abstract submission with a poster or oral presentation at a scientific meeting, or 
disclosure by other means.
The results of this trial will be subject to public disclosure on external web sites according to 
international and national regulations, as reflected in the Novo Nordisk Code of Conduct for 
Clinical Trial Disclosure27.
Novo Nordisk reserves the right to defer the release of data until specified milestones are reached, 
for example when the clinical trial report is available. This includes the right not to release the 
results of interim analyses, because the release of such information may influence the results of the 
entire trial.
At the end of the trial, one or more scientific publications may be prepared collaboratively by the 
investigator(s) and Novo Nordisk. Novo Nordisk reserves the right to postpone publication and/or 
communication for up to 60 days to protect intellectual property.

In all cases the trial results will be reported in an objective, accurate, balanced and complete 
manner, with a discussion of the strengths and limitations. 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 Editors52 (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.

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

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 disease1. All of these patients were diagnosed with MTC 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 MTC, it is common clinical practice to explore the family 
history of MTC or MEN2 and perform a genetic test for RET (re-arranged during transfection) 
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 MTC and two were diagnosed with 
C-cell hyperplasia, resulting in a positive predictive value of a C-cell anomaly of 50%.
Diagnostic evaluation should include: 
!
Thyroid ultrasound examination 
!
If available and 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 
biopsy may add important clinical information about the need for surgery
2.3
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 CT > 10 ng/L to screen for C-cell 
disease, but they do not provide sufficient information on patients with basal CT > 10 and < 20 ng/L 
to allow conclusions2,3.

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 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 UNL
!
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). 
1.5
Neoplasm
All events of neoplasms (excluding thyroid neoplasms, which will be reported under thyroid 
disease) must be reported during the trial and the following additional information must be reported

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).
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 V9A. 
Furthermore, a blood sample for assessment of anti-semaglutide IgE antibodies should be drawn as 
soon as possible after the event and at V9A 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.

Thereafter, repeat testing (at central laboratory) of ALT, AST, ALP and total bilirubin should be 
done regularly until the abnormalities return to normal or baseline state. Additional clinical 
information such as related symptoms, risk factors and contributing conditions (e.g. viral hepatitis, 
autoimmune hepatitis, alcoholic hepatitis, hepatobiliary or pancreatic disorders) should be gathered 
to seek a possible cause of the observed laboratory test abnormalities.
*Please note that risk of liver injury defined as ALT or AST > 3x UNL and total bilirubin > 2x 
UNL, where no alternative aetiology exits (Hy’s law), should also be reported as a SAE (important 
medical event, according to protocol Section 12.1.2).

condom (by the partner), intrauterine device, sponge, spermicide or oral contraceptives.
For Czech Republic only: Adequate contraceptive measures are always one highly reliable method 
(such as intrauterine device, sterilisation of one of the partners, hormonal birth control methods) 
plus one supplementary barrier method (such as condom, diaphragm) with a spermicide. In 
justified cases, this combination may be replaced with a double-barrier method with a spermicide. 
Total sexual abstinence may also be considered contraception. (Please note: hormonal 
contraception should always be discussed with a gynaecologist).

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. Other minor corrections and clarifications 
1.1
Additional eye examinations and additional data collection on diabetic retinopathy
Updated sections in the protocol: 2, 4.2.2.2, 8.4.1.2, 8.4.4, 12.1.5, 17.4.2.2, 18.1, 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 treatment123. 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. 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 programme. 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 sections in the protocol: 8.4.2, 18.1
, text is added to highlight the investigators 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 sections in the protocol: 6.6, 8.1.4, 8.1.5, 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
Other minor adjustments, clarifications and correction of typographical errors
Updated sections in the protocol: 8.4.8, 12.7.2, 17.2, 17.3.1, 17.4.2.1
Laboratory analysis
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
Table 12-2 has been aligned with Table 12-1 reflecting that unstable angina pectoris (UAP) require 
hospitalisation to qualify for Event Adjudication.
Statistical considerations
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 imputation, 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.
In the section “Time to event endpoint” stratification factors have been added in error and will be

2.4
Section 8.1.4 
End-of-treatment (visit 8) and Follow-up (visit 9)
At V8 the subject should be reminded about the importance of attending the follow-up visit (V9). If
the subject, nonetheless, does not attend V9, 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 V9. (For 
subjects who discontinue trial product, see Section 8.1.5) 
In case the subject cannot be reached (by site visit or phone contact) at the scheduled visit 9, 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 (visits 8A 
and 9A)
Subjects should continue with the originally scheduled site contacts after visit V9A and up to and 
including visit V8. After visit V9A, samples for antibodies, PK and lactate assessment should not be 
taken. If necessary, in order to retain the subject in the trial, site visits can be replaced by phone 
contacts after visit V9A. However, as a minimum, these subjects should be asked to attend the 
scheduled end-of-treatment visit (V8) at week 26 as these visits 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 scheduled V8, should not be 
considered withdrawn from the trial. In case the subject cannot be reached (by site visit or phone 
contact) at the scheduled V8, 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 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 V8 (or V9A if it is scheduled after 
V8). The site should in due time prepare for establishing contact with the subject within the visit 
window of the scheduled V8 if the subject has agreed to attend these visits. 
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).
2.6
8.1.6.1
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: V9 for subjects who have completed treatment, whereas for subjects who have discontinued 
trial product prematurely the last visit is V8 (or V9A if it is scheduled after V8). 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).

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, eye examination category, 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 (V9)
!

Section 17.3.1
Primary analysis for the primary estimand
Missing values for each group will be imputed as follows:
!
An analysis of covariance (ANCOVA) with region as a categorical fixed effect 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 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 from baseline to week 26 in 
HbA1c will be analysed using an ANCOVA with treatment and region as categorical fixed effects 
and baseline HbA1c as covariate. The results obtained from analysing the datasets will be combined 
using Rubin’s rule47 to draw inference.
2.15
Section 17.4.2.1
Efficacy endpoints (Binary efficacy endpoints)
!
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.
!
The binary endpoint will be created for each of the 100 1000 complete data sets
!
Each of the created complete data set will be analysed with the logistic model and inference 
will be drawn using Rubin’s rule47.
Time to event endpoint
The endpoint will be described and compared for oral semaglutide versus placebo using likelihood 
ratio tests obtained from a Cox proportional hazards model with treatment, stratification factors, the 
interaction between the two stratification factors and region as categorical fixed effects and baseline 
HbA1c as a covariate. From this analysis the estimated Hazard ratios between oral semaglutide 
versus placebo will be presented together with 95% confidence intervals and two sided p values for 
test of no difference.

diabetes after initiation of intensive antidiabetic treatment52,53,54. 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 progression55,56 even in intensively treated patients who experienced early 
worsening53. 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 
placebo57. 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 trial58.

Section 18.1
General precautions
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)58

Changes
2.1
Changes to section 6.4 Rescue Criteria
6.4 Rescue criteria
Subjects with persistent and unacceptable hyperglycaemia should be offered treatment
intensification. To allow time for dose escalation and to observe the expected effect of treatment on
glycaemic parameters, rescue criteria will be applied from week 8 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 (at the central laboratory) should be obtained
by calling the subject for a re-test. If the confirmatory FPG also exceeds the values described below,
the subject should be offered rescue medication (i.e. initiation of anti-diabetic medication):
!
13.3 mmol/L (240 mg/dL) from week 8 to the end of week 13
!
11.1 mmol/L (200 mg/dL) from week 14 to the end-of-treatment
Guidance text requested by Serbian Health Authorities: The safety of the individual subject always 
has the highest priority. Thus, the rescue criteria represent the minimum criteria for when rescue 
medication should be initiated. At the investigator’s discretion, rescue medication can be initiated 
in case of FPG values lower than those stated in the rescue criteria or before week 8 in case of a 
specific safety concern.
It is important for the integrity of the trial that only subjects actually needing treatment
intensification (as defined above) are started on rescue medication. Subjects who are started on
rescue medication should continue to follow the protocol-specified visit schedule. Rescue
medication should be prescribed at investigator’s discretion as add-on to randomised treatment and
according to ADA/European Association for the Study of Diabetes guidelines25, 26 (excluding 
GLPRAs, DPP-4 inhibitors and amylin analogues).

Introduction
1.1
Trial information
This is a 26-week, randomised, double-blinded, placebo-controlled, four-armed, parallel-group, 
multi-centre, multi-national trial comparing the efficacy and safety of three dose levels of once-
daily oral semaglutide and placebo in subjects with type 2 diabetes mellitus treated with diet and 
exercise only.
Primary objective
To compare the effects of three dose levels of once-daily oral semaglutide (3, 7 and 14 mg) versus 
once-daily placebo on glycaemic control in subjects with type 2 diabetes mellitus treated with diet 
and exercise only.
Secondary objectives
To compare the effects of three dose levels of once-daily oral semaglutide (3, 7 and 14 mg) versus 
once-daily placebo on body weight in subjects with type 2 diabetes mellitus treated with diet and 
exercise only.
To compare the safety and tolerability of three dose levels of once-daily oral semaglutide (3, 7 and 
14 mg) versus once-daily placebo in subjects with type 2 diabetes mellitus treated with diet and 
exercise only.
Trial design
Subjects with type 2 diabetes treated with diet and exercise only will after approximately 2 weeks 
screening period be randomised in a 1:1:1:1 manner to receive either a dose of 3, 7, or 14 mg of oral 
semaglutide or placebo once daily. After the treatment period of 26 weeks, all subjects enter a 
follow-up period of 5 weeks ended by a follow-up visit. The total trial duration for the individual 
subject will be approximately 33 weeks. For further details, see the trial protocol.
1.2
Scope of the statistical analysis plan
This statistical analysis plan (SAP) is based on the protocol for trial NN9924-4233 “Efficacy and 
safety of oral semaglutide versus placebo in subjects with type 2 diabetes mellitus treated with diet 
and exercise only”, version 3.0 (18 November 2016), and includes more detailed procedures for 
executing the statistical analyses of the primary and secondary endpoints. Statistical analyses and a 
number of clarifications additional to those specified in the trial protocol are pre-specified with this 
SAP. All changes to the statistical analyses planned in the trial protocol are documented in section
3.
Novo Nordisk will be responsible for the statistical analyses and reporting.

Statistical considerations
General considerations
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.
1. The randomisation is stratified based on descent (Japanese subjects/non-Japanese subjects).
The information regarding descent will be included based on country details from the IWRS.
Descent (Japanese subjects/non-Japanese subjects) will be included in the statistical analyses
as part of region. The regions are: Europe (Bulgaria, Czech Republic, Russian Federation,
Serbia, and Turkey), North America (United States), South America (Mexico), Africa
(Algeria), and Asia (Japan).
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 the below three comparisons with associated two-sided 95% confidence intervals and 
p-values corresponding to two-sided tests of no difference:
!
Oral semaglutide 14 mg vs. placebo
!
Oral semaglutide 7 mg vs. placebo
!
Oral semaglutide 3 mg vs. placebo
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 primary trial objective will be defined as follow: 
!
Primary estimand – ‘Treatment policy’
–
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 treatment policy 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 treatment adherence 
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 – ‘Hypothetical’
–
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 hypothetical 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.
Analogously, two estimands will be pre-defined for the remaining secondary endpoints addressing 
the secondary objective. 
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, 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 potential initiation of rescue medication. Initiation of rescue medication is 
expected to be more frequent in the placebo arm and in the oral semaglutide 3 mg arm than for the 
two highest dose levels of oral semaglutide. A higher proportion of subjects are expected to 
discontinue treatment due to AEs in the oral semaglutide 14 mg arm, compared to the other 
treatment arms. 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.
2.1
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 at each dose level (3 mg, 7 mg, and 14 mg).
The sample size calculation is made to ensure a power of at least 90% to jointly confirm HbA1c
superiority of oral semaglutide vs. placebo at each dose level out of the six pre-specified 
confirmatory hypotheses shown in Figure 2–1. The closed testing procedure described in Bretz et 
al.1 is used to control the overall type I error at a nominal two-sided 5% level. The statistical testing 
strategy is built on the following two principles:
!
Within a dose level, glycaemic effect must be established in terms of HbA1c superiority 
before testing for added benefits in terms of body weight superiority.
!
Glycaemic effect in terms of HbA1c superiority must be established on all higher dose levels 
before continuing testing hypotheses on lower dose levels.
The sample size is calculated using the calcPower function in the R package, gMCP2 using 10000 
simulations. All of the six 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 common 
standard deviations used across dose levels are given in Table 2–1. These are primarily based on the 
oral semaglutide phase 2 results (NN9924-3790) and supported by results from the s.c. semaglutide 
phase 2 trial (NN9535-1821).
Since the equalising effect of rescue medication will be included in the primary analysis as well as 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 a 75% 
smaller effect in these subjects. The adjusted treatment effects for testing superiority are defined as 
0.8×TE + 0.2×TE×0.25.

Definition of analysis sets
The following analysis sets will be defined:
Full analysis set (FAS): Includes all randomised subjects. Subjects in the FAS will contribute to 
the evaluation “as randomised”.
Safety analysis set (SAS): Includes all subjects exposed to at least one dose of trial product. 
Subjects in the SAS will contribute to the evaluation based on the trial product received for the 
majority of the period where they were on treatment. This will be referred to as contributing to the 
evaluation “as treated”.
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 (V9) for subjects on trial product
!
The latest occurring visit of the end-of-treatment visit (V8) or the follow-up premature 
discontinuation visit (V9A), 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 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 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 a 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, eye examination category, 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 (V9)
!
The follow-up prematurely discontinuation visit (V9A)
!
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 end date is 
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 for estimating the primary 
estimand. The on-treatment without rescue medication observation period will be the primary 
observation period when estimating the secondary estimand. 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 event adjudication committee (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 should 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 (CTR).

Confirmatory hypotheses
For the primary HbA1c endpoint and the confirmatory secondary body weight endpoint the 
following confirmatory one-sided hypotheses are planned to be tested at each dose level of 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 six confirmatory hypotheses related to the HbA1c and body weight 
endpoints will be preserved in the strong sense at 5% (two-sided) using the weighted Bonferroni-
based closed testing procedure described in Bretz et al.1 and outlined in Figure 2–1.
The first hypothesis to be tested is superiority of HbA1c at the highest dose level. It will be tested at 
the overall significance level (5%) while allocating 0% local significance level to the remaining of 
the hypotheses. For this hypothesis, and in general, if a hypothesis is confirmed, then the 
significance level will be reallocated according to the weight and the direction of the edges going 
from the confirmed hypothesis to the next hypotheses as specified in Figure 2–1. Each of the 
following hypotheses will be tested at their updated local significance level (α-local). This process 
will be repeated until no further hypotheses can be confirmed.
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 its local two-sided significance level as defined by the closed 
testing procedure in Figure 2–1. This is equivalent to using a one-sided p-value (nominal α = 0.025) 
and a one-sided 2.5% overall significance level in the closed testing procedure.

Primary endpoint
The primary endpoint is change from baseline to week 26 in HbA1c.

Primary analysis for the primary estimand

random (MAR) within the groups used for imputation. Imputation of missing data at week 26 will 
be done within 8 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 as a categorical fixed effect 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 1000 values for 
each subject with missing week 26 data based on region and baseline HbA1c. Thus, 1000 
complete data sets will be generated including observed and imputed values.
The number of subjects in the groups who at week 26 have discontinued trial product or initiated 
rescue medication are expected to be relatively low. Therefore the region variable included in the 
imputation model will be reduced in levels avoiding estimation problems due to sparse data. The 
regions to be used in these imputations are defined as North America and Other. 
Analysis used for confirming superiority versus placebo at week 26:
For each of the 1000 (now complete) imputed data sets the change from baseline to week 26 in 
HbA1c will be analysed using an ANCOVA with treatment and region as categorical fixed effects 
and baseline HbA1c as covariate. The results obtained from analysing the datasets will be combined 
using Rubin’s rule3 to draw inference.
From this analysis the estimated treatment differences between each of the oral semaglutide dose 
levels and placebo together with associated two-sided 95% confidence intervals and unadjusted 
two-sided p-values for testing no difference from zero will be presented.
2.3.2
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 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 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. 
For subjects who do not have post-baseline assessments for planned visits available in the on-
treatment without rescue medication period, the baseline value will be carried forward to the first 
planned visit to ensure that all randomised subjects will contribute to the statistical analysis. 
2.3.3
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 EMA recommendations4
and with a report from the US National Research Council5, these analyses will evaluate the 
sensitivity of the results due to the impact of missing data. 
The evaluation of the robustness of the primary analysis results will 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. 
Sensitivity analyses for the primary estimand
The estimation of the primary estimand will be repeated using the following sensitivity analyses:
!
A comparator multiple imputation analysis based on FAS using the in-trial observation 
period
!
A comparator multiple imputation analysis differentiating between reasons for discontinuing 
treatment prematurely based on FAS using the in-trial observation period
!
A tipping-point multiple imputation analysis based on FAS using the in-trial observation 
period
Sensitivity analyses for the secondary estimand
The estimation of the secondary estimand will be repeated using the following sensitivity analyses:

A tipping-point multiple imputation analysis based on FAS using the on-treatment without 
rescue medication observation period.

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 AEs 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.
!
Tipping-point multiple imputation analysis: In this sensitivity analysis, missing data will 
first be imputed according to the primary analysis for the treatment policy estimand. For the 
hypothetical estimand imputation will be done as described below for the binary endpoints 
(see section 2.4.2.1). Secondly, for all oral semaglutide treatment arms a penalty will be 
added to the imputed values at week 26. The approach is to gradually increase this penalty 
until all confirmed HbA1c conclusions from the primary analysis are changed. For each 
hypothesis tested the specific value of the penalty that reverses the conclusion will be used 
to evaluate the robustness of the primary analysis results. 
2.3.3.2
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.
2.4
Secondary endpoints
2.4.1
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. 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 local two-sided significance level resulting from the closed testing procedure in 
Figure 2–1. Sensitivity analyses similar to the ones pre-specified for the primary HbA1c endpoint 
will be made to evaluate the robustness of the body weight results.

The above continuous endpoints will be analysed separately using similar model approaches as for 
the primary endpoint with the associated baseline value as a covariate. The following endpoints will
be log-transformed prior to analysis with the associated log-transformed baseline value as a 
covariate: Fasting C-peptide, fasting insulin and proinsulin, fasting glucagon, insulin resistance, 
CRP, and fasting lipid profile.
For evaluation of the primary estimand the analyses will be performed at week 26. This will result 
in imputation of missing data within 8 groups as described for the week 26 evaluation in section 
2.3.1. 
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. The baseline will not be carried forward to first planned 
visit if the first planned visit falls later than 8 weeks after randomisation.
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)
!
Body weight loss ≥ 5 %
!
Body weight loss ≥ 10 %
!
HbA1c < 7.0 % (53 mmol/mol) without hypoglycaemia (treatment -emergent severe or BG-
confirmed symptomatic hypoglycaemic episodes) and no weight gain
!
HbA1c reduction ≥ 1 %-point (10.9 mmol/mol) and weight loss ≥ 3 %
Missing data for the above six binary endpoints will be accounted for using multiple imputation 
techniques. For the treatment policy estimand the binary endpoints will be calculated as 
dichotomisations of the 1000 multiple imputations underlying the primary MI analysis. For the 
hypothetical estimand the model will be implemented using a sequential imputation approach
assuming MAR. The imputation will be done as described below:
!
Intermittent missing values in the on-treatment without rescue observation period are 
imputed using a Markov Chain Monte Carlo (MCMC) method, in order to obtain a 
monotone missing data pattern. This imputation is done for each treatment group separately 
and 1000 copies of the dataset will be generated.
!
A sequential regression approach for imputing monotone missing values at planned visits 
will be implemented starting with the first visit after baseline and sequentially continuing to 
the planned end of treatment visit. For each treatment group an analysis of covariance model

will be used to impute missing values at each planned visit. The model will include region 
as categorical effects and baseline and post-baseline values prior to the visit in question as 
covariates.
The binary endpoints will be derived as dichotomisations of the 1000 multiple imputations from the 
sequential imputation.
For both estimands, each of the 1000 datasets will be analysed using a logistic regression model 
with treatment and region as fixed effects and baseline value as covariate (i.e. baseline HbA1c for 
binary HbA1c endpoints, baseline body weight for body weight endpoints and both baseline HbA1c
and baseline body weight for the composite binary endpoints that comprise both parameters). The 
results will be combined using Rubin’s rule to draw inference.
Only observed data within the corresponding observation period will be included for the ‘without 
hypoglycaemia’ component of the composite endpoint. Because the number of hypoglycaemic 
episodes are expected to be very low in this trial, the observed data is considered sufficient when 
addressing both estimands.
For the composite endpoints involving both HbA1c and body weight the imputed datasets will be 
combined by imputation number.
Time to event endpoints
!
Time to additional anti-diabetic medication (to support the treatment policy estimand)
!
Time to rescue medication (to support the hypothetical estimand)
Definition of additional anti-diabetic medication: New anti-diabetic medication initiated at or 
after randomisation and before (planned) end-of-treatment.
Definition of rescue medication: New anti-diabetic medication initiated at or after randomisation 
and before last date on trial product. This is a subset of the additional anti-diabetic medication.
The following rule will be applied based on the concomitant medication data reported by the 
investigator, to determine whether or not the recorded anti-diabetic medication can be considered an
new anti-diabetic medication:
1. New anti-diabetic medication: Anti-diabetic medication (4 th level ATC code) that is 
initiated at or after randomisation and with a dosing duration of more than 21 days 
More than 21 days are chosen as a minimum duration for the medication to be considered as ‘anti-
diabetic medication’. This threshold is set to ensure that short-term durations (i.e., ≤21 days) of 
anti-diabetic medication (e.g., in connection with concurrent illnesses) are not included because 
such intensifications are not likely to affect the effect endpoints.

The analysis supporting the treatment policy estimand is addressed for the FAS using the in-trial 
observation period and additional anti-diabetic medication will be considered an event regardless of 
whether or not subjects prematurely discontinued treatment. Time from randomisation to additional 
anti-diabetic medication will be analysed using a Cox proportional hazards model with treatment 
and region as categorical fixed effects and the baseline HbA1c value as a covariate. From this 
analysis the estimated hazard ratios between each of the oral semaglutide dose levels and placebo 
together with associated two-sided 95% CIs and unadjusted two-sided p-values will be presented. 
The endpoint aims to address the need of additional anti-diabetic medication regardless of whether 
this is due to lack of effect or related to tolerability of the trial product. Switching to another anti-
diabetic treatment is therefore also considered an event and withdrawn subjects or subject lost to 
follow-up will be considered as having an event (started on additional anti-diabetic medication) on 
the day of withdrawal. Subjects will be censored on the day before the planned end-of-treatment 
visit. 
The analysis supporting the hypothetical estimand is addressed for the FAS using the on-treatment 
without rescue medication observation period. Time from first dose of trial product to initiation of 
rescue medication will be analysed using the same model as described above. The endpoint aims to 
address a lack of effect of treatment with trial product. Only initiation of rescue medication as add-
on to randomised treatment is considered an event; switching to another anti-diabetic treatment is 
not considered an event (initiation of rescue medication) and as a consequence subjects will be 
censored on the day before date of last trial product. Potential events occurring between 
randomisation and first date on trial product will be included in the analysis as events on first date 
of trial product, in order to account for all events of rescue medication initiation. 
2.4.2.2
Safety endpoints and safety assessments
The safety endpoints and safety assessments will be evaluated based on SAS using the on-treatment 
observation period and based on SAS using the in-trial observation period unless otherwise stated. 
The following endpoints and assessments are used to support the safety objectives.
Adverse events 
!
Number of treatment-emergent adverse events (TEAEs) during exposure to trial product,

All AEs will be coded using version 20.1 of the Medical Dictionary for Regulatory Activities

A treatment-emergent AE is defined as an AE with onset in the on-treatment observation period 
(see definition of observation periods in section 2.2).

Classification of hypoglycaemia
Hypoglycaemic episodes will be summarised for the SAS and the on-treatment observation period 
only.
Treatment-emergent: hypoglycaemic episodes will be defined as treatment-emergent if the onset of 
the episode occurs within the on-treatment observation period (see definition of observation periods 
in section 2.2).
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 2–2).
Novo Nordisk classification of hypoglycaemia
In normal physiology, symptoms of hypoglycaemia occur below a PG level of 3.1 mmol/L 
(56 mg/dL)6. Therefore, Novo Nordisk has included hypoglycaemia with PG levels below this cut-
off point in the definition of 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 classification7 or BG-confirmed by a PG value < 3.1 mmol/L (56 mg/dL) with
symptoms consistent with hypoglycaemia.

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

Pharmacokinetic and/or pharmacodynamic modelling
Data from this trial will be evaluated using population pharmacokinetic analysis and exposure-
response for semaglutide. The purpose of the population pharmacokinetic analysis will be: 
!
To describe the covariate factors (such as weight, age, gender, race and ethnicity) that 
influence semaglutide exposure
!
To estimate a steady-state exposure level for each subject with pharmacokinetic data, in 
order to facilitate subsequent exposure-response analyses
The purpose of the exposure-response analyses will be to support the recommended dose, by 
investigating response and potentially side effects across the exposure range. 
The population pharmacokinetic (PK) and exposure-response analyses will be conducted as a meta-
analysis, including all relevant oral semaglutide phase 3a trials with PK assessments. A separate 
modelling analysis plan will be prepared before first database lock in the oral semaglutide phase 3a 
programme, outlining details of the analyses. The modelling will be performed by Quantitative 
Clinical Pharmacology at Novo Nordisk A/S and will be reported separately from the clinical trial 
report.

A more detailed description of the handling of the four patient reported outcomes (PRO) 
questionnaires used in the trial is provided in the following sections.
No multiplicity adjustments will be done for the PRO questionnaires.
2.7.1
SF-36v2® (acute version) health survey
The SF-36v2® Health Survey (SF-36v2) (acute version) instrument is a commonly used generic 
instrument measuring health-related quality of life (HRQoL)/general health status across disease 
areas including diabetes. The SF-36v2 is a PRO questionnaire for adults and contains 36 items (see 
Table 2–3).
A total of 35 items measure eight domains of functional health and well-being as well as two 
summary domains with a 1-week recall period: physical functioning (10 items), role limitation due 
to physical health problems (4 items), bodily pain (2 items), general health perceptions (5 items), 
vitality (4 items), social functioning (2 items), role limitations due to emotional problems (3 items) 
and general mental health (5 items), mental component score (MCS), physical component score 
(PCS). There is an additional single item giving information on health change o ver the past week.
Domain scores
Norm-based scores (NBS) will be derived using the QualityMetric Health Outcomes™ Scoring 
Software8 including the 2009 US general population norm used for all the oral semaglutide phase 3a 
programme trials. Version 4.5 of the QualityMetric Health Outcomes™ Scoring Software available 
at time of licensing will be used. Table 2–3 provides an overview of the domains. NBS standardises 
domain and component scores into T-scores using the means and standard deviations from the US 
general population. Higher scores on all domains and component summary measures (PCS and 
MCS) indicate better HRQoL/general health status. Item 2 (i.e. Question 2 in the eCRF) is not 
included in any score.

Mental component summary (MCS)
NA
The MCS score is also a weighted 
average of the 8 domain scores. 
Weights differ from PCS to MCS. 
Missing data at instrument level will be handled using the Maximum Data Recovery method: The 
method applies a value to a domain item rendered missing if at least one of the items in that domain 
has valid data. A domain score is considered missing if all item values in the domain are missing. 
PCS and MCS are calculated when at least seven of the eight domains have valid data, either actual 
or estimated. However, to calculate PCS, the PF domain must be one of the seven domains having 
valid data. Also, to calculate MCS, the MH domain must be one of the seven domains having valid 
data.
The domains will be evaluated using the primary analysis for the treatment policy estimand for the 
CTR. The domains will be evaluated using the primary analysis for the hypothetical estimand in a 
report separate from the CTR.
Responder threshold values
The responder threshold values, see section 2.7.4, in terms of T-score points for change from 
baseline are defined in Table 2–48.

Impact of Weight on Quality of Life Clinical Trials Version (IWQOL-Lite-CT)
The IWQOL-Lite-CT is designed to assess the impact of changes in weight on patients' quality of 
life within the context of clinical trials. The items of the IWQOL-Lite-CT pertain to physical 
functioning and psychosocial domains and all items employ a 5-point graded response scale (never, 
rarely, sometimes, usually, always; or not at all true, a little true, moderately true, mostly true, 
completely true). 
Composite scores
All IWQOL-Lite-CT composite scores range from 0 to 100, with higher scores reflecting better 
levels of functioning. Table 2–5 provides an overview of domains.

Missing data at instrument level will be handled in the following way. Raw scores for each subscale 
are computed if a minimum of 50% of the items for that subscale are non-missing, and for the 
IWQOL-Lite-CT total score if a minimum of 75% of all items are non-missing.
The scoring is done in three steps:

1. If the minimum number of items are answered for a composite, compute the average of the 
valid item responses for that composite where 1 = ”never” or “not at all true” and 5 = ”always” 
or “completely true.” This average must be a number between 1 and 5, inclusive.
2. Multiply that average by the total number of items in that composite. The total number of items 
in each IWQOL-Lite-CT composite is as follows: Psychosocial = 13, Physical = 7, Physical 
Function = 5, Pain/Discomfort = 2, IWQOL-Lite-CT Total = 20. Round to the nearest integer.
3. To convert the IWQOL-Lite-CT raw score (as calculated above) to the 0 (worst) to 100 (best) 
metric:
a.
Subtract the raw score from the maximum raw score for each composite. The maximum 
raw scores are as follows: Psychosocial = 13x5 = 65, Physical = 7x5 = 35, Physical 
Function = 5x5 = 25, Pain/Discomfort = 2x5 = 10, IWQOL-Lite-CT Total = 20x5 = 100.
b. Divide the difference in (a) by the raw score range for each composite. The ranges of the 
raw scores are as follows: Psychosocial = 65-13 = 52, Physical = 35-7 = 28, Physical 
Function = 25-5 = 20, Pain/Discomfort = 10-2 = 8, IWQOL-Lite-CT Total = 100-20 = 80.
c.
Multiply the total in (b) by 100.
Responder threshold values
The data from this trial is used as part of the confirmation of the psychometric properties of 
IWQOL-Lite-CT in patients with type 2 diabetes mellitus. To estimate potential responder threshold 
values, see section 2.7.4, for the composite scores in IWQOL-Lite-CT anchor-based and 
distribution-based methods are applied to data in this trial. 
As a consequence, it is not possible to specify responder threshold values before database lock for 
this trial. 
IWQOL-Lite-CT data will be presented using summary statistics at the item level. Scoring and 
analyses will be reported after the CTR. These analyses will be done for all domains in Table 2–5. 
The domains will be evaluated using the primary analysis for the both the treatment policy estimand 
and the hypothetical estimand in a report separate from the CTR.
2.7.3
Patient Global Impression of Status (PGI-S) and Patient Global Impression of 
Change (PGI-C)
PGI-S assesses patients’ impression of physical functioning and mental health status during the 
clinical trial. The PGI-S contains two items evaluated on a 5-point graded response scale.

PGI-C assesses patients’ impression of change in physical functioning and mental health during the 
clinical trial compared to when they entered the trial. The PGI-C contains two items evaluated on a 
7-point graded response scale.
Descriptive statistics (frequencies of answers per response scale point) will be given for PGI-S and 
PGI-C item level data. No scores will be derived and as a consequence scores will not be analysed.
2.7.4
Responder analyses for PRO to be reported in a separate report
Responder analyses will be reported in a report separate from the CTR for SF-36v2® and IWQOL-
Lite-CT. These additional analyses were not in scope during the development process of the 
protocols for the NN9924 phase 3a programme. Responder analyses will be conducted for both 
estimands, for the same time points that are defined for the analyses of PRO endpoints and 
separately for each domain.
For descriptive statistics the following subject responder categorisation is applied for all relevant 
time points and domains:
!
Responder (improvement): Individual change from baseline in score ≥ positive responder 
threshold
!
Non-responder (no change): Individual change from baseline in score > negative responder 
threshold value and < positive responder threshold value
!
Non-responder (worsening): Individual change from baseline in score ≤ negative responder 
threshold value
The following binary subject responder definition is applied for all relevant time points and scores:
!
Responder: Individual change from baseline in score ≥ positive responder threshold
!
Non-responder: Individual change from baseline in score < positive responder threshold
The binary responder endpoints will be analysed as the other supportive secondary binary effect
endpoints (section 2.4.2.1). Estimated proportions and differences in proportions will be reported in 
addition to odds and odds ratios.

Changes to the statistical analyses planned in the protocol
The main analyses were described in the protocol for trial NN9924-4233. However, clarifications, 
more detailed descriptions of endpoints and analyses are provided in this SAP. The changes from 
protocol NN9924-4233 are summarised below:
!
It has been specified which countries belong to which regions.
!
The primary and secondary estimand has changed name from de-facto and de-jure to
treatment policy and hypothetical, respectively.
!
The MMRM sensitivity analysis of the primary estimand has been omitted in section 2.3.3.
It is considered sufficient to keep the two current sensitivity analyses to stress test the
primary results.
!
For the MMRM analyses, it is specified that for subjects who do not have post-baseline
assessments for planned visits available in the on-treatment without rescue medication
period, the baseline value will be carried forward to the first planned visit, if the first
planned visit do not fall later than 8 weeks after randomisation, to ensure that all randomised
subjects will contribute to the statistical analyses.
!
The three MI sensitivity analyses of the secondary estimand have been omitted in section
2.3.3. It is considered sufficient to keep the tipping point sensitivity analysis for the
secondary hypothetical estimand as it can be considered as a progressive stress-testing to
assess how severe departures from missing at random must be in order to reverse the
conclusions from the primary MMRM analysis used to address the hypothetical estimand.
!
The LOCF sensitivity analysis specified in the trial protocol (section 17.3.3.2) has been
omitted, as it is not realistic that subjects with missing data would have had stable results
from the point of dropout to trial completion.
!
The statistical analysis of the two binary effect endpoints: HbA1c reduction ≥1 %-point
(10.9 mmol/mol); and body weight loss ≥ 3 %, have been omitted, because they are being
analysed as a part of the two composite binary effect endpoints.
!
For the binary efficacy endpoints, it has been specified how missing data in the analyses for
the hypothetical estimand will be imputed using a sequential imputation approach assuming
MAR.
!
It has been specified which assessments will be analysed on the logarithmic scale.

The definitions of initiation of rescue medication and additional anti -diabetic medication 
used for the time-to-event endpoints as well as the accompanying statistical analyses have 
been further clarified.
!
It has been specified that all safety laboratory results (except amylase and lipase) are safety 
assessments and not safety endpoints as written in the trial protocol.
!
The pre-specified analyses of severe or BG-confirmed symptomatic hypoglycaemic 
episodes will not be performed due to sparse data.
!
Only one of the four PRO questionnaires, SF-36v2® Health Survey (SF-36v2) (acute 
version), will be analysed statistically, and only for the primary analysis of the primary 
estimand. 
The responder analyses, and the primary analysis for the secondary estimand of SF-36v2® 
will be presented in a report separate from and after finalisation of the CTR. The three other 
PRO questionnaires, IWQOL-Lite-CT and PGI-S/PGI-C, will be presented using summary 
statistics in the CTR. 
Statistical analysis of the IWQOL-Lite-CT questionnaires will be presented in a report 
separate from and after finalisation of the CTR.
