Summary
Objectives and endpoints:
Primary objective
To compare the effect of once-daily dosing of three dose levels (3 mg, 7 mg and 14 mg) of oral 
semaglutide versus sitagliptin 100 mg once-daily, both in combination with metformin with or 
without sulfonylurea (SU), on glycaemic control in subjects with type 2 diabetes mellitus (T2DM).
Secondary objectives
To compare the effect of once-daily dosing of three dose levels (3 mg, 7 mg and 14 mg) of oral 
semaglutide versus sitagliptin 100 mg once-daily, both in combination with metformin with or 
without SU, on body weight in subjects with T2DM.
To compare the long-term safety and tolerability of once-daily dosing of three dose levels (3 mg, 
7 mg and 14 mg) of oral semaglutide versus sitagliptin 100 mg once-daily, both in combination 
with metformin with or without SU, in subjects with T2DM.

Trial design:
The trial is a 78 week, randomised, double-blind, double-dummy, active-controlled, parallel-group, 
multi-centre, multi-national, four-armed trial.
Subjects with T2DM inadequately controlled with metformin or metformin + sulfonylurea (SU) 
will be randomised in a 1:1:1:1 manner to receive either a dose of 3 mg, 7 mg or 14 mg of oral 
semaglutide once-daily or a dose of 100 mg sitagliptin once-daily.
Total trial duration for the individual subject will be approximately 85 weeks. The trial includes a 2 
week screening period, followed by a 78 week randomised treatment period and a follow-up period 
of 5 weeks. 
Trial population:
It is planned to randomise 1860 subjects.
Key inclusion criteria
!
Male or female, age ≥ 18 years at the time of signing informed consent.
For Japan only: Male or female, age ≥ 20 years at the time of signing informed consent.
!
Diagnosed with T2DM ≥ 90 days prior to day of screening.
!
HbA1c 7.0-10.5 % (53-91 mmol/mol) (both inclusive).
!
Stable daily dose of metformin (≥1500 mg or maximum tolerated dose as documented in 
subject medical record) alone or in combination with SU (≥ half of the maximum approved dose 
according to local label or maximum tolerated dose as documented in subject medical record) 
within 90 days prior to the day of screening.

3.1
Background information
3.1.1
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 liver.3
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 control.5,6
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 islets.7,8 Subjects 
with T2DM have a decreased incretin effect.9-12 However, the insulinotropic action of GLP-1 and 
thus, the ability to lower BG levels, is preserved when GLP-1 is administered at supra physiological 
levels.13 In addition, supra physiological levels of GLP-1 induces reduction in body weight 14. GLP-
1 is a physiological regulator of appetite and food intake and GLP-1receptors 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 exposure
14-16. These mechanisms of action make GLP-1 an attractive pharmacological treatment for 
T2DM.17-19
3.1.3
Oral semaglutide 
Semaglutide is a long-acting GLP-1 receptor agonist (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 very 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-aminoisobuztyric acid, a synthetic 
amino acid) and position 34 (lysine to arginine) and acylation of the peptide backbone with a spacer 
and C-18 fatty di-acid chain to lysine in position 26.20The 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 very low when administered orally, semaglutide has been co-formulated with the 
absorption enhancing excipient sodium N-(8-(2-hydroxybenzoyl) amino) caprylate (SNAC) in order 
to increase bioavailability based on the 
 concept developed by 
 
. When semaglutide is co-formulated with SNAC, SNAC has the capacity to 
augment the absorption of semaglutide across the gastrointestinal (GI) epithelium. The absorption 
enhancement by SNAC is dose, size and time-dependent and is believed to take place in close 
proximity of the tablet in the stomach. The absorption process is hampered if dosed with food, 
liquid or in the presence of significant stomach content. Throughout this document oral semaglutide 
will refer to the drug product, that is, semaglutide co-formulated with 300 mg SNAC. 
Novo Nordisk is currently also developing semaglutide for once-weekly subcutaneous (s.c.) 
administration in subjects with T2DM. 
3.1.4
Non-clinical data
3.1.4.1
Semaglutide
The non-clinical programme for semaglutide was designed according to the ICH M3 guideline 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 low21.
Embryo−foetal development toxicity
Semaglutide caused embryo-foetal development toxicity in the rat through a GLP-1 receptor 
mediated effect on the inverted yolk sac placenta leading to impaired nutrient supply to the 
developing embryo. Primates do not have an inverted yolk sac placenta which makes this 
mechanism unlikely to be of relevance to humans and cynomolgus monkeys. In the developmental 
toxicity studies in cynomolgus monkey, a marked pharmacology mediated maternal body weight 
loss coincided with increased early foetal loss; however, there was no indication of a teratogenic 
potential of semaglutide in this species. These data suggest an important species-dependent 
mechanism, whereby semaglutide is teratogenic in rats but not in primates.
A review of results from the non-clinical studies can be found in the investigator’s brochure (IB) for 
Semaglutide (subcutaneous administration), edition 1022 and the IB for Oral administration of 
semaglutide (NN9924), edition 623, 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 (MAA) submission has been conducted including a 26-week carcinogenicity study in 
transgenic rasH2 mice and a 2-year carcinogenicity study in Sprague-Dawley rats.

The carcinogenicity studies demonstrated that SNAC was not carcinogenic to the transgenic rasH2 
mouse or the Sprague-Dawley rat. The doses tested covered plasma exposures (AUC) of 2-fold in 
the mouse and up to 44-fold in the rat when compared to the mean human exposure following a 
clinical dose of 300 mg SNAC/day.
A review of results from the non-clinical studies can be found in the IB for Oral administration of

3.1.5
Clinical data 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 623, or any updates hereof.
3.1.5.1
Pharmacokinetics
In single dose trials, oral semaglutide has demonstrated a long mean terminal half-life (t½) ranging 
from 153 to 161 hours (~1 week) and a median time to reach maximum observed concentration 
(tmax) ranging from 1 to 2 hours in healthy subjects. 
In multiple-dose pharmacokinetics (PK) trials, the exposure to oral semaglutide increased with 
increasing dose. Overall, the pharmacokinetic properties of semaglutide appeared similar in healthy 
subjects and in subjects with T2DM.
Exposure of semaglutide exhibits a substantially greater dose-to-dose variation following oral 
administration compared to s.c. administration. However, when administered orally once-daily the 
PK properties of semaglutide, i.e. low clearance and long half-life, will limit the variation in steady 
state plasma exposure.
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. The tablet can be taken with up to half a 
glass of water (approximately 120mL/4 fluid oz).
Drug-drug interaction (DDI) investigations have explored the effect of oral semaglutide on the 
exposure to lisinopril, warfarin, metformin and digoxin as well as the effect of omeprazole on oral 
semaglutide and SNAC. It was demonstrated that oral semaglutide did not change the exposure to 
lisinopril, warfarin or digoxin, but increased the exposure to metformin when taken simultaneously. 
The increase in exposure to metformin may be related to delayed gastric emptying caused by 
semaglutide as observed for other GLP-1 RAs. Based on the wide therapeutic index of metformin, 
the increased exposure to metformin was however not considered clinically relevant. Further, it was

demonstrated that the exposure to semaglutide appeared to be slightly higher when administered 
with omeprazole in comparison to semaglutide alone, but the effect was not statistically significant 
or considered clinically relevant.  In subjects with mild to end-stage renal impairment, the exposure 
to semaglutide appeared similar in subjects with normal and impaired renal function, whereas the 
AUC for SNAC was greater in subjects with impaired renal function than in subjects with normal 
renal function. The Cmax of SNAC appeared similar in subjects with normal and impaired renal 
function. The renal clearance of all SNAC metabolites was decreased in subjects with renal 
impairment. 
In subjects with mild to severe hepatic impairment, the exposure to semaglutide appeared to be 
unaffected by the degree of hepatic impairment, whereas the exposure to SNAC (in terms of both 
AUC and Cmax) was increased for subjects with hepatic impairment as compared to subjects with 
normal hepatic function.
All tablets of oral semaglutide contain 300 mg of SNAC. 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 metabolized 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 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 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, common
adverse events (AEs) included nausea and vomiting, most of them of mild to moderate 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 studies 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.

3.1.6
Sitagliptin
The selected active comparator in this trial is sitagliptin, an oral antidiabetic drug (OAD) of the 
DPP-4 inhibitor (DPP-4i) class suitable for once-daily oral administration. Sitagliptin was 
developed by Merck & Co and has been marketed since 2006 under the trade name Januvia®. By 
inhibition of the enzyme DPP-4, which breaks down GLP-1 and gastric inhibitory polypeptide 
(GIP), secretion of insulin is increased and release of glucagon is suppressed. 
Further information can be obtained in the locally approved Januvia® label24.
For an assessment of benefits and risks of the trial, see Section 18.1.
3.2
Rationale for the trial
The rationale for the present trial is to compare the efficacy and safety of once-daily dosing with 
three dose levels (3 mg, 7 mg and 14 mg) of oral semaglutide with sitagliptin 100 mg once-daily in 
subjects with T2DM. Furthermore, the trial will ensure that long-term safety data are collected from 
subjects with T2DM exposed to oral semaglutide for a minimum of 18 months, as recommended by 
U.S. Food and Drug Administration (FDA)24.

Trial design
5.1
Type of trial
The trial is a 78 week, randomised, double-blind, double-dummy, active-controlled, parallel-group, 
multi-centre, multi-national trial with four arms comparing efficacy and safety of oral semaglutide 
3 mg, 7 mg and 14 mg once-daily with sitagliptin 100 mg once-daily. Subjects with T2DM 
inadequately controlled on metformin alone or in combination with SU will be randomised in a 
1:1:1:1-manner to receive either:
!
oral semaglutide 3 mg and sitagliptin placebo
!
oral semaglutide 7 mg and sitagliptin placebo
!
oral semaglutide 14 mg and sitagliptin placebo
!
sitagliptin 100 mg and oral semaglutide placebo
Randomisation will be stratified according to anti-diabetic pre-trial background medication 
(metformin or metformin + SU) to ensure even distribution of the four treatment arms within strata.
To maintain the blinding of the trial, the treatment will consist of two tablets daily as the sitagliptin 
tablet is not visually identical to the oral semaglutide tablets (see Section 9.1).
Total trial duration for the individual subject will be approximately 85 weeks. The trial includes a 
2 week screening period, followed by a 78 week randomised treatment period and a follow-up 
period of 5 weeks.
A schematic diagram of the trial design is shown in Figure 5–1.

efficacy endpoint will be evaluated at week 26 (see Section 17). No interim analysis will be done 
and the blinding will remain throughout the trial in order to assess long-term safety and tolerability 
in an un-biased manner (see Section 17). Supportive secondary efficacy endpoints are also included 
at week 52 and week 78.
5.3
Treatment of subjects
Treatment of subjects is summarised in Table 5–1.
Oral semaglutide treatment arms
All subjects randomised to semaglutide will initiate treatment with 3 mg once daily. Subjects 
randomised to maintenance doses of 7 mg or 14 mg will follow a fixed dose-escalation regimen 
with 4 weeks between the dose escalation steps. The maintenance dose of 7 mg once daily will be 
reached after 4 weeks on 3 mg once daily. The maintenance dose of 14 mg once daily will be 
reached after 4 weeks on 3 mg once daily, followed by 4 weeks on 7 mg once daily. In addition, all 
subjects randomised to oral semaglutide will receive sitagliptin placebo once daily. 
Sitagliptin treatment arm
Subjects randomised to sitagliptin will receive 100 mg once daily without dose escalation. In 
addition, all subjects randomised to sitagliptin will receive oral semaglutide placebo once daily.

5.3.1
Dosing instructions
Absorption of oral semaglutide is significantly affected by food and fluid in the stomach, hence 
dosing should be in the morning in fasting state and at least 30 minutes before the first meal of the 
day. Trial products can be taken with up to half a glass of water (approximately 120 ml/4 fluid oz). 
The tablets must be taken whole: do not break or chew (see Table 9–2). Furthermore, other oral 
medication can be taken 30 minutes after trial products.

5.3.2
Background medication
After inclusion (V1), subjects must continue anti-diabetic pre-trial background medication (i.e. 
metformin alone or in combination with SU) throughout the entire trial. The background medication 
must be maintained at the stable, pre-trial dose and at the same frequency during the whole 
treatment period unless rescue medication is needed (see Section 6.4) or if the subject has 
unacceptable hypoglycaemia on a background of SU in which case the dose of SU can be reduced.
In addition, all background medication:
!
is considered to be non-investigational medicinal product (NIMP)
!
will not be provided by Novo Nordisk A/S
!
should be used in accordance with standard of care or local label in the individual country 
!
must not exceed the maximum approved dose in the individual country
 
5.4
Treatment after discontinuation of trial product
When discontinuing trial products the subject should be switched to a suitable marketed product at 
the discretion of the investigator (for Brazil only: or it will be made available according to local 
regulations). After discontinuation of trial product, GLP-1 RAs are not allowed before completion 
of the follow-up visit (see Section 8.1.4 and 8.1.5) which is to take place 5 weeks after the last date 
on trial product (to avoid interference with the antibody analysis).
As this trial is a phase 3a trial, oral semaglutide will not be available for prescription until after 
marketing authorisation.
5.5
Rationale for treatment
The doses of oral semaglutide have been chosen based on the data from the phase 2 dose-finding 
trial. The selected doses are expected to have the optimal benefit risk profile for further 
development for treatment of T2DM. The duration and doses of randomised treatments are 
considered adequate to collect sufficient data on efficacy and safety in accordance with the trial 
objectives.
Sitagliptin has been chosen as comparator since it is an established OAD within the DPP-4i drug 
class.

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 central laboratory) should be obtained by 
calling the subject for a re-test:
!
14.4 mmol/L (260 mg/dL) from week 8 to end of week 13
!
13.3 mmol/L (240 mg/dL) from week 14 to end of week 25
!
11.1 mmol/L (200 mg/dL) from week 26 to end of trial
If the confirmatory FPG also exceeds the values described above, the subject should be offered 
rescue medication (i.e. intensification of existing anti-diabetic background medication and/or 
initiation of new anti-diabetic medication). 
In addition, subject should be offered rescue medication if:
!
HbA1c (at central laboratory) > 8.5% (69.4 mmol/mol) from week 26 to end of trial 
It is important for trial integrity that only subjects actually needing treatment intensification (as 
defined above) are started on rescue medication. Subjects that are started on rescue medication 
should continue to follow the protocol-specified visit schedule. Rescue medication should be 
prescribed 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. Rescue medication is considered to be 
NIMP and will not be provided by Novo Nordisk.

6.5
Premature discontinuation of trial product
All efforts should be made to keep the subject on trial product.
However, if necessary for safety concerns related to trial product, or unacceptable intolerability, as 
judged by the investigator, treatment with trial product must be discontinued (i.e. a treatment 
discontinuation call must be made in the interactive web response system (IWRS)) and in these 
cases trial product should not be re-initiated. In case the trial product is interrupted due to suspicion 
of acute pancreatitis, please see Section 8.7.1.
Furthermore, the subject must discontinue treatment with trial product if any of the following 
applies:
!
pregnancy
!
intention of becoming pregnant
!
included in the trial in violation of the inclusion and/or exclusion criteria
!
participation in another clinical trial with an investigational medicinal product (IMP)
!
calcitonin ≥ 100 ng/L
Subjects discontinuing treatment with trial product will not be withdrawn from trial and will be 
followed as described in Section 8.1.5.
The primary reason for discontinuation of trial product must be specified in the eCRF.
6.6
Withdrawal criteria
This section refers to withdrawal from the trial. 
The subject may withdraw at will at any time. The subject’s request to withdraw from trial must 
always be respected.
Subjects who agree to attend or provide health status at the planned V16 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.
Subjects who consider withdrawing informed consent should be encouraged to have procedures 
performed according to the V16A and V17A visits.
See Section 8.1.6 for procedures to be undertaken in case of withdrawal from trial.

A subject included in the trial in violation of the inclusion and/or exclusion criteria must 
discontinue treatment with trial product, but will not be withdrawn from the trial. The subject will 
be followed as described in Section 8.1.5.
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.

Subject replacement
Subjects who are withdrawn will not be replaced

Rationale for trial population
Subjects with T2DM inadequately controlled on metformin alone or in combination with SUs will 
be included in the trial. The eligibility criteria allow for enrolment of a relatively broad trial 
population. This will ensure that the trial population will resemble the target population in common 
practice. However, concomitant conditions which could jeopardise the safety of the subjects or 
compliance with the protocol will preclude subjects from participating (see Section 6.3).

Recruitment:
The screening and randomisation rate will be followed closely via the IWRS in order to estimate 
when to stop screening. All investigators will be notified immediately when the recruitment period 
ends, after which no further subjects may be screened and the IWRS will be closed for further 
screening.
Trial registration:
Information of the trial will be disclosed at clinicaltrials.gov, novonordisk-trials.com and the 
Clinical Trials Information JapicCTI site clinicaltrials.jp. According to the Novo Nordisk Code of 
Conduct for Clinical Trial Disclosure27, it will also be disclosed according to other applicable 
requirements such as those of the International Committee of Medical Journal Editors (ICMJE)28,
the Food and Drug Administration Amendment Act (FDAAA)29, European Commission 
Requirements30,31 and other relevant recommendations or regulations. If a subject requests to be 
included in the trial via the Novo Nordisk e-mail contact at these web sites, Novo Nordisk may 
disclose the investigator’s contact details to the subject. As a result of increasing requirements for 
transparency, some countries require public disclosure of investigator names and their affiliations.

Methods and assessments
8.1
Visit procedures
Each subject will attend 16 site visits and 1 phone visit. Subjects who prematurely discontinue trial 
product will also be asked to attend V16A and V17A, but will not be asked to attend V17.
For visit numbers, timing of site and phone visits and visit windows during the trial period, please 
refer to the flow chart, Section 2. Planned visits can be re-scheduled within the allowed visit 
window. It is the responsibility of the investigator to ensure that all site visits occur according to the 
flow chart.
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. Subjects will be invited for the next scheduled visit 
according to the visit schedule.
If a subject is unable or unwilling to attend all subsequent visit(s) the investigator should at least 
aim to have the subject attend the V8, V12 and the End-of-treatment visit (V16) as these visits
should be performed for all subjects (except subjects who withdraw informed consent, see 
Section 8.1.6).
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.
8.1.1
Screening, visit 1
The investigator must keep a subject screening log, a subject identification code list and a subject 
enrolment log. The subject screening log and subject enrolment log may be combined in one list. 
In addition, 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.
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 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 CRF 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 CRF. Follow-up of 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. However, in case any laboratory samples are not available (e.g. 
haemolysed/lost), 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 having consumed only water within the last 8 hours prior to the visit. Trial 
product must be taken after blood sampling and other oral medication can be taken 30 minutes after 
trial products.
Glucose lowering agents and trial product should not be taken until after blood sampling has been 
performed.
If subjects do not attend the visit in a fasting state they must be asked to attend a re-scheduled visit 
within the visit window to have all planned visit assessments performed. Only AEs should be 
captured in the eCRF at the original visit.
8.1.3
Randomisation and trial product administration
Eligible subjects will be randomised into one of four treatment arms. The randomisation session 
must be performed in the IWRS which will allocate the dispensing unit number (DUN) of trial 
product to be dispensed to the subject.
All visit 2 assessments should be performed before administration of first dose of trial product.
Trial product (see Section 9) will be dispensed to the subject by the site, hospital pharmacy or 
equivalent at each site visit during the trial from randomisation to last visit before the End-of-
treatment visit (see Section 2). The investigator must document that subjects are instructed in the 
dosing requirements at every dispensing visit, please see Section 5.3.1.
Date and time of first administration of trial product will be captured in the eCRF.

8.1.4
End-of-treatment (visit 16) and Follow-up (visit 17)
Subjects who stay on trial product throughout the trial, must attend the End-of-treatment visit (V16) 
78 weeks after randomisation and the Follow-up visit (V17) 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 16 (see Section 10).
In case the subject cannot be reached (by clinic visit or phone contact) at the scheduled visit 17 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) to collect health status. If no health status can be collected, the subject should be 
considered lost to follow up. 
8.1.5
Premature discontinuation of trial product and Follow-up (visits 16A and 17A)
Subjects who discontinue trial product prematurely should attend visit 16A, scheduled to take place 
shortly after discontinuation of trial product. Visit 17A should be scheduled 5 weeks (+3 days visit 
window) after the last date on trial product. A treatment discontinuation session must be performed
in the IWRS at visit 16A (see Section 10).
Subjects should continue with the originally scheduled site contacts after visit 17A and up to visit 
16. If necessary, in order to retain the subject in the trial, site visits can be replaced by phone 
contacts after V17A. However, as a minimum, these subjects should be asked to attend the 
scheduled V8 at week 26, V12 at week 52 and End-of-treatment (V16) at week 78.
In case the subject cannot be reached (by clinic visit or phone contact) at the scheduled visit 16 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) to collect health status. If no health status can be collected, the subject should be 
considered lost to follow up. 
8.1.6
Withdrawals
If a subject considers withdrawing from the trial, the investigator must aim to undertake procedures 
similar to those for visit 16A as soon as possible and visit 17A should be scheduled 5 weeks (+3
days visit window) after the last date on trial product, if the subject agrees to it.
The end-of-trial form must be completed and final drug accountability must be performed even if 
the subject is not able to come to the trial site. A treatment discontinuation session must be made in 
the IWRS (see Section 10). The case book must be signed. 
Although a subject is not obliged to give his/her reason(s) for withdrawing from a trial, the 
investigator must make a reasonable effort to ascertain the reason(s), while fully respecting the

must be specified on the end-of-trial form in the eCRF.
8.1.7
Investigator assessments
Review of diaries, PROs, laboratory reports, ECGs and fundoscopy/fundus photography must be 
documented either on the documents and/or in the subject’s medical record.
If clarification of entries or discrepancies in the diary or PROs is needed, the subject must be 
questioned and a conclusion made in the subject’s medical record. Care must be taken not to bias 
the subject.
The documents must be retained at the site as source documentation.
For ECGs, physical examinations and eye examinations the evaluations must follow the categories:
!
Normal
!
Abnormal
–
Was the result clinically significant? (yes/no)
The evaluation should be based on investigators judgement.
For laboratory report values outside the reference range, the investigator must specify whether the 
value is clinically significant or not clinically significant. All laboratory printouts must be signed 
and dated by the investigator prior to the following visit. The signed laboratory report is retained at 
the site as source documentation.
In case of abnormal clinically significant findings found as a result of screening procedures 
conducted at visit 1 or assessments revealing baseline conditions at visit 2 the investigator must 
state a comment in the subject’s medical record and record this in the medical history/concomitant 
illness form in the eCRF. 
The Investigator or his/her delegate must collect and review the PROs and diaries for completeness 
and to ensure that AEs are reported.

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.
The subject will be instructed to perform a 7-point SMPG profile four 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.
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, the values in the eCRF 
should be corrected.
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, height and BMI
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.
BMI will be calculated for the investigators convenience at visit 1 in the eCRF but will not be saved 
in the clinical database. The equation used in the eCRF is listed below:
BMI kg/m2 = body weight (kg)/(Height (m) x Height (m)) or (kg/m2 = [lb/in2 x 703])
All BMI calculations will subsequently take place in the clinical database using measurements of 
height and weight according to flowchart 2.

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 0.5 cm or 
0.2 inches using a non-stretchable measuring tape. The same measuring tape should be used 
throughout the trial (measuring tape will be provided to the sites).
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.
8.3.5
Patient reported outcomes questionnaires
PRO will be assessed using the questionnaires:
!
SF-36v2™ (acute version) health survey37-39
!
IWQoL-Lite Clinical Trial Version40,41
!
CoEQ42-45
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 three questionnaires. Subjects should be given the opportunity to complete 
the questionnaires by themselves without interruption. All results from the PRO questionnaires 
must be transferred into the eCRF.
The questionnaires SF-36v2™and IQWoL-Lite Clinical Trial Version are commonly used PRO 
instruments, also in the T2DM area. The Control of Eating questionnaire has not been developed to 
be used in clinical trials. However, it has previously been included in clinical trials on an item per 
item basis, among others in a T2DM population.
All the questionnaires will be translated to local language before being handed out to the subjects 
participating in the trial. 
SF-36 acute version

Eye examination 
Dilated fundoscopy/fundus photography will be performed as per flow chart (see Section 2) by the 
investigator or according to local practise. Results of the dilated fundoscopy/fundus photography 
will be interpreted by the investigator (see Section 8.1.7).
If dilated fundoscopy/fundus photography has been performed within 90 days prior to
randomisation the procedure does not need to be repeated, unless worsening of visual function since 
the last examination. The results must be available prior to randomisation.
If the dilated fundoscopy/fundus photography is performed before the subject has signed the 
informed consent form, it must be documented in the medical records that the reason for performing 
the procedure was not related to this trial.
8.4.4
Electrocardiogram – 12 –lead
12-lead ECG will be performed as per flowchart (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 post-baseline ECG is suggestive of new myocardial infarction 
(MI), the investigator will be notified and, unless already done, the investigator should report this as 
AE or SAE at investigator’s discretion (see Section 12.1).
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).

should be documented in medical records.
Contraceptive methods
Female subjects of childbearing potential must ensure using adequate contraceptive methods until 5 
weeks after the last date on trial product.
For Germany only: Only highly effective methods of birth control are accepted (i.e. one that results 
in less than 1% per year failure rate when used consistently and correctly such as implants, 
injectables, combined oral contraceptives, some intrauterine device), or sexual abstinence or 
vasectomised partner.
For United Kingdom only: Adequate contraceptive measures are defined as established use of oral, 
intravaginal, transdermal combined estrogen and progestogen hormonal methods of contraception; 
oral, injected or implanted progestogen only hormonal methods of contraception; placement of an 
intrauterine device or intrauterine hormone releasing system, bilateral tubal occlusion, barrier 
methods of contraception (condom or occlusive cap with spermicidal 
foam/gel/film/cream/suppository), female sterilisation, vasectomised partner (where partner is sole 
partner of subject), or true abstinence (when in line with preferred and usual lifestyle).
For Brazil only: For women who expressly declare free of the risk of pregnancy, either by not 
engaging in sexual activity or by having sexual activity with no birth potential risk, use of 
contraceptive method will not be mandatory.
For Japan only: Adequate contraceptive measures are abstinence (not having sex), diaphragm,
condom (by the partner), intrauterine device, sponge, spermicide or oral contraceptives.
For Argentina only: Birth control methods will be reimbursed by Novo Nordisk Pharma Argentina

Antibodies
Blood samples will be drawn for measurement of serum antibodies to 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 neutralising 
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

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) or symptoms have been resolved in 
accordance to current guidelines33.
An 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.

Stop date and time of hypoglycaemic episode (stop time is the first time the plasma glucose 
value is > 3.9 mmol/L (70 mg/dL and/or symptoms have been resolved)).
If a stop date and time is not reported a hypoglycaemic episode will cover a period of 60 
minutes.
!
The plasma glucose level before treating the episode (if available) and any follow up 
measurements. 
The lowest value measured during the hypoglycaemic episode will be reported as the plasma 
glucose value for the episode, the remaining values will be kept as source data.
!
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, time and dose of last trial product administration and other anti-diabetic treatments 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 or other acute disease.
!
Whether the subject was asleep when the episode occurred.
o
If yes, whether the symptoms of the episode woke up the subject.
The answer to the question: "Was 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 concentration33.
Oral carbohydrates should not be given if the subject is unconscious.

o
General malaise: headache or malaise (feeling discomfort/unease)
o
Other symptoms?
The Investigator must review the diary at each contact 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 date, SMPG value and whether the subject was able to self-treat 
due to decreased validity of such data 35,36.
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, IgE anti-semaglutide antibodies and PK samples will be 
analysed by a special laboratory and Novo Nordisk A/S (see Sections 8.4.7, 8.6.1 and 8.7.2. For
some of the analyses described in Section 8.7.1 and 8.7.1 a local laboratory must be used.
The handling, transportation and storage of biological samples are described in the laboratory 
manual (for central and special laboratory details see Attachment I).
Samples will be coded in order to keep subject identity anonymous.
Laboratory samples not drawn on the day of the actual visit should preferably be drawn on another 
day within the visit window stated in the flow chart (see Section 2). Please note that a laboratory 
sample pertaining to a specific visit must always be reported to that visit.
For some of the samples drawn during the trial, subjects will be asked to attend the site visits fasting 
(fasting for blood sampling is defined in Section 8.1.2).
The central laboratory will provide laboratory results to the investigator on an on-going basis and 
the investigator must review all laboratory results for signs of concomitant illness and AEs and 
report these according to Section 8.7 and 12). However, anti-semaglutide antibody and semaglutide 
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 
(CTR).
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. 
For Brazil only: All laboratory results will be communicated to the investigators.
All laboratory samples will be destroyed at the latest at the completion of the CTR, except samples 
obtained for anti-semaglutide antibody analysis. Antibody samples may be retained until drug 
approval by FDA and/or European Medicines Agency (EMA). The retained antibody samples may 
be used for further characterisation of antibody responses towards drug if required by health 
authorities or for safety reasons, see Section 24.2.
For Brazil only: Biological samples from Brazil will be destroyed at the end of the trial.

8.5.1
Fasting plasma glucose
FPG is measured in order to evaluate glycaemic control. The subject must attend these visits fasting
(see Section 8.1.2).
Low FPGs reported by a laboratory in connection to trial related visits, i.e. FPG results ≤ 3.9 
mmol/L (70 mg/dL), should not be reported as hypoglycaemic episodes but as an AE (e.g. a FPG 
result of 2.9 mmol/L (52 mg/dL) should be reported as “low plasma glucose of 2.9 mmol/L (52 
mg/dL)”). See Section 12 for reporting of AEs.

Other assessments
8.6.1
Pharmacokinetics
The blood samples for the population PK will be drawn in a sub population for bioanalysis of
semaglutide plasma concentrations (see Section 2). The sub population will include approximately 
50% of all randomised subjects and the selection of sites to participate will be done in collaboration 
with local Novo Nordisk affiliate. The investigator must record the exact date and time for sampling 
the blood for PK analysis in the eCRF. The date and time of the latest trial product administration 
prior to the visit must be recorded by the subject in the subject diary and transcribed to the eCRF by 
the investigator.
8.6.2
Subject diary
The diaries should be handed out at the visit described in the flow chart Section 2. The recordings 
must be reviewed as described in Section 8.1.7 and transcribed to the eCRF at the following visit.
Entries in the diaries are only to be made by the subject, unless otherwise specified.
The investigator should instruct the subject in recording the following data in the diary:
!
date and time of first trial product administration
!
date and time of last trial product administration prior to visits with PK sampling
!
hypoglycaemic episodes
!
changes in concomitant medication

8.7.1
Assessments in case of suspicion of acute pancreatitis
Most patients with acute pancreatitis experience 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 relief.46 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 pancreatitis.46 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 features47: 
!
abdominal pain consistent with acute pancreatitis (acute onset of a persistent, severe, epigastric 
pain often radiating to the back)
!
serum lipase activity (and/or amylase activity) at least three times greater than the upper limit of 
normal
!
characteristic findings of acute pancreatitis on imaging.
If acute pancreatitis is ruled out, trial product should be re-initiated.
If acute pancreatitis is confirmed, appropriate treatment and careful monitoring of the subject 
should be initiated. The subject must be discontinued from trial product (treatment discontinuation 
call), but should remain in the trial (see Section 6.5 and 8.1.5). The event should be reported as an 
AE requiring additional data collection (see Section 12.1) and Appendix B) and will undergo 
assessment by the EAC (see Section 12.7.2).
8.7.2
Assessments in case of suspicion of hypersensitivity reactions
In case of suspicion of a severe immediate systemic hypersensitivity reaction48 to the trial product, 
the subject must be discontinued from trial product but should remain in the trial (see 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 V17A.

Furthermore, a blood sample for assessment of anti-semaglutide IgE antibodies should be drawn as 
soon as possible after the event and at V17A and sent to central laboratory for analysis. Tryptase 
concentrations, if available, should be included in the specific event form when reporting the AE.
In case of suspicion of immune complex disease48, the subject must be discontinued from trial 
product but should remain in the trial (see 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.
The event should be reported as an AE requiring additional data collection (see Section 12.1 and 
Appendix B).
8.7.3
Assessments in case of increased levels of creatine kinase
In case of CK > 10x upper normal level (UNL) prompt repeat testing (at central laboratory) of CK 
should be done. Repeat testing (at central laboratory) should be done regularly until CK levels 
return to normal or baseline state. Additional clinical information should be gathered to seek 
possible cause of the observed CK elevation. 
The event should be reported as an AE requiring additional data collection (see Section 12.1 and 
Appendix B).
8.7.4
Assessments in case of increased levels of aminotransferases
In case of
1. ALT or AST >3x UNL and total bilirubin >2x UNL,
the event must be reported as an SAE (see Section 12.1). 
2. ALT or AST >10x UNL and total bilirubin ≤2x UNL, 
the event should be reported as an AE requiring additional data collection(see Section 12.1 and 
Appendix B).
For both events prompt repeat testing (at central laboratory) including ALT, AST, ALP and total 
bilirubin should be done and discontinuation of trial product considered. 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 should be gathered 
to seek a possible cause of the observed laboratory test abnormalities.

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 dose packs. 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 subjects 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 
IWRS. 
At the randomisation visit (visit 2) 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 should discontinue treatment with trial product but be asked to continue in the 
trial (see Section 8.1.5). A treatment discontinuation session must be completed in IWRS.

12 Adverse events, technical complaints and pregnancies
12.1
Definitions
Adverse event 
An adverse event (AE) is any untoward medical occurrence in a subject administered a 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 procedures (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 8.4.8. 
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.
Serious adverse event
An 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. 
Suspicion of transmission of infectious agents via the trial product must always be considered 
an SAE. 
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 dyscrasiasis or convulsions that do not result in hospitalisation, or development of drug 
dependency or drug abuse.
Trial specific serious adverse event
The following laboratory abnormalities must be reported as an SAE:
!
ALT or AST >3x UNL and total bilirubin >2x UNL
Additional assessments should be made for events meeting the above criterion (see Section 8.7.4).
Non-serious adverse event
A non-serious AE is any AE which does not fulfil the definition of an SAE.

Adverse events requiring additional data collection
Adverse events requiring additional data collection are events which, in the evaluation of safety, 
have a special focus (e.g. required by the health authorities). The AEs requiring additional data 
collection are:
!
Acute coronary syndrome (myocardial infarction or hospitalisation for unstable angina)

!
Medication error (concerning trial products):
o
Administration of wrong drug. 
Note: Use of wrong DUN is not considered a medication error.
o
Wrong route of administration.
o
Administration of an overdose with the intention to cause harm (e.g. suicide 
attempt).
o
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.
!
Lactic acidosis
!
Creatine kinase (CK) > 10x UNL
!
Hepatotoxicity events:
o
ALT or AST > 10x UNL and total bilirubin ≤ 2x UNL
o
Hepatotoxicity leading to trial product discontinuation 
Technical complaint
A technical complaint is any written, electronic, or oral communication that alleges product

Reporting of adverse events
All events meeting the definition of an AE must be collected and reported. This includes events 
from the first trial-related activity after the subject has signed the informed consent until the end of 
the post-treatment follow-up period (V17) for subjects on trial product OR until the end of trial 
(V16 or V17A, whichever comes last) for the subjects who have discontinued trial product 
prematurely. 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. Novo Nordisk assessment of expectedness is performed according to the following 
reference documents: 
!
IB for Oral administration of semaglutide (NN9924), edition 623 and any updates hereof. 
!
Summary of Product Characteristics (SmPC) for Januvia® (sitagliptin)50 and any updates hereof.
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 event specific forms and the additional 
information to report).
In case any of the above 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 Event Adjudication Form will

Initial reporting of AEs
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 GCP.1 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 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 GCP1, unless 
locally this is an obligation of the investigator.
Novo Nordisk products used as concomitant medication:
If an SAE is considered to have a causal relationship with a Novo Nordisk marketed product used 
as concomitant medication in the trial, it is important that the suspected relationship is reported to 
Novo Nordisk, e.g. in the alternative aetiology section on the 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 ongoing at time of death (where death is due to another AE) 
may be closed with the outcome “recovering/resolving” or “not recovered/not resolved”. Cases 
can be closed with the outcome of “recovering/resolving” when the subject has completed the 
follow-up period and is expected by the investigator to recover.
The SAE follow-up information should only include new (e.g. corrections or additional) 
information and must be reported within 24 hours of the investigator's first knowledge of the 
information. This is also the case for previously non-serious AEs which subsequently become 
SAEs.
!
Non-serious AEs: Non-serious AEs must be followed until the outcome of the event is 
“recovering/resolving”, “recovered/resolved” or “recovered/resolved with sequelae” or until the 
end of the follow-up period stated in the protocol, whichever comes first, and until all queries 
related to these AEs have been resolved. Cases of chronic conditions, cancer or AEs ongoing at 
time of death (where death is due to another AE) may be closed with the outcome 
“recovering/resolving” or “not recovered/not resolved”. Cases can be closed with the outcome 
of “recovering/resolving” when the subject has completed the follow-up period and is expected 
by the investigator to recover.
The investigator must ensure that the 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.

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 I tablets
!
Sitagliptin 100 mg or placebo II 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. A technical 
complaint form for each code number or for each DUN 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 print or copy of the technical complaint form must be 
sent with the sample.
The investigator must ensure that the technical complaint sample contains the code number and, if 
available, the DUN.
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(s).
The investigator must follow the pregnancy until the pregnancy outcome and the newborn infant is 
one month of age.
The investigator must report information about the pregnancy, pregnancy outcome and health of the 
newborn infant(s), as well as AEs in connection with the pregnancy and AEs in the foetus and 
newborn infant.
The following must be collected and reported by the investigator to Novo Nordisk - electronically 
(e.g. in PDF format), or by fax or courier:
1. Reporting of pregnancy information
Information about the pregnancy and pregnancy outcome/health of the newborn infant(s) has to 
be reported on Maternal Form 1A and 1B, respectively. 
When the pregnancy outcome is abnormal (i.e. congenital anomalies, foetal death including 
spontaneous abortion and/or any anomalies of the foetus observed at gross examination or 
during autopsy) and/or when a congenital anomaly is diagnosed within the first month, further 
information has to be reported for the female subject on Maternal Form 2. In addition, 
information from the male partner has to be reported on the Paternal Form, after an informed 
consent has been obtained from the male partner. 
Initial reporting and follow-up information must be reported within 14 calendar days of the 
investigator's first knowledge of initial or follow-up information. 
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.

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.
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 (mild/moderate) include: hunger, slight headache, 
nausea, light-headedness, palpitations and sweating. Severe hypoglycaemia may produce loss of 
consciousness. Symptoms of non-severe hypoglycaemia should be treated by ingestion of 
carbohydrates.
Severe hypoglycaemia resulting in loss of consciousness should be treated at the investigator’s 
discretion according to best available medical practise.
One case of accidental overdose of oral semaglutide was reported in the NN9924-3692 trial in a 
subject treated with 
 mg oral semaglutide once daily. The subject accidentally took the trial 
product 
. No AEs were reported at the same time. The medication error 
was discovered at the next scheduled visit. The subject did not report any symptoms and treatment 
was continued without any change.
One case of accidental overdose has been reported in s.c. semaglutide once weekly treated subjects. 
The case classified as moderate in severity and considered to be probably related to semaglutide 
was reported by a subject enrolled in the trial NN9535-1821. No hospitalisation was needed. 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

(NN9924), edition 623, and any updates hereof.
12.7
Committees related to safety
12.7.1
Novo Nordisk safety committee
Novo Nordisk will constitute an internal oral semaglutide safety committee to perform ongoing 
safety surveillance. The oral semaglutide safety committee may recommend unblinding of any data 
for further analysis and in this case an independent ad hoc group will be established in order to 
maintain the blinding of the trial personnel.
12.7.2
Event adjudication committee
An independent external event adjudication committee (EAC) is established to perform qualitative 
or quantitative 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 EACs 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 requirements51.
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 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 independence and 
in-depth analysis of each event, will be attributed with greater importance of the two. The outcome

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
In addition paper AE forms and paper SIFs will be provided. These must be used when access to the 
eCRF is revoked or if the eCRF is unavailable. The paper technical complaint form must also be 
used for complaints that are not subject specific.
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 CRF data may be made by the investigator or the investigator's delegated staff.
An audit trail will be maintained in the CRF application containing as a minimum: the old and the 
new data, identification of the person entering the data, date and time of the entry and reason for the 
correction.
If corrections are made by the investigator's delegated staff after the date 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.

14 Monitoring procedures 
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 CRFs, the trial site's recruitment rate and the compliance 
of the trial site to the protocol and GCP, but will not exceed 12 weeks for trial sites with active 
subjects (defined as subjects in screening, treatment or follow-up).
The monitor must be given direct access to 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 CRF (BMI and age are not 
source data verified as they are calculated in EDC).
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 CRFs 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 must 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 CRF. 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.

17 Statistical considerations
General considerations
The blinding of the randomised treatments will be maintained until the database has been released 
for statistical analysis. No interim analyses or other analyses of unblinded data will be performed 
before the database is locked.
If necessary, a statistical analysis plan (SAP) may be written in addition to the protocol, including a 
more technical and detailed elaboration of the statistical analyses. The SAP will be finalised before 
database lock.
Data from all sites will be analysed and reported together. 
In statistical analyses where stratification is included, the two combinations (metformin; 
metformin+SU) will be included based on the actual information collected through the eCRF. In 
case of missing eCRF information the information collected from IWRS system will be used.
The latest available measurement, at or prior to the randomisation visit, will be used as the baseline 
measurement. If no measurement(s) have been obtained, at or prior to randomisation, the baseline 
value will be left missing.
Laboratory values below the lower limit of quantification (LLoQ) will be set to ½LLoQ. Number of 
values below LLoQ by treatment and visit will be summarised if deemed relevant.
The primary and confirmatory efficacy endpoints will be confirmed at week 26. This approach will 
result in a lower proportion of missing data compared to the expected proportion of missing data at 
week 52 and week 78 and therefore a more reliable estimate of efficacy. 
Results from a statistical analysis will as a minimum be presented by the estimated treatment 
contrasts for the below three comparisons at week 26, week 52 and week 78 with associated two-
sided 95% confidence intervals and p-values corresponding to two-sided tests of no difference:
!
oral semaglutide 14 mg vs. sitagliptin 100 mg
!
oral semaglutide 7 mg vs. sitagliptin 100 mg
!
oral semaglutide 3 mg vs. sitagliptin 100 mg
If no statistical analysis is specified, data will be presented using relevant summary statistics.

Primary and secondary estimands
Two estimands adressing different aspect of the trial objective will be defined; a primary de-facto 
(effectiveness) estimand and a secondary de-jure (efficacy) estimand: 
!
Primary estimand
o
de-facto treatment difference at week 26 for all randomised subjects
!
Secondary estimand 
o
de-jure treatment difference at week 26 for all randomised subjects if all subjects 
adhered to treatment and did not initiate rescue medication
The primary de-facto estimand assesses the average effect in a future population that results from 
initiating treatment with oral semaglutide including potential rescue medication(s) as compared to 
initiating treatment with sitagliptin 100 mg including potential rescue medication(s). Generalisation 
of this estimand depends among other things on the extent to which the use of rescue medication 
and treatment adherence in this trial reflects clinical practice. All post-baseline scheduled visit data 
will be included in the analysis, including data collected after discontinuation of trial product or 
initiation of rescue medication(s).
The secondary de-jure estimand assesses the glycaemic benefit a future subject is expected to 
achieve if initiating and continuing treatment with oral semaglutide as compared to sitagliptin 100 
mg. It is considered a clinically relevant estimand as it provides information to treating clinicians 
about the expected glycaemic efficacy of oral semaglutide compared to sitagliptin 100 mg for 
purposes of treating individual subjects. Generalisation of this estimand depends among other 
things on the extent to which the compliance to trial product administration in this trial reflects 
clinical practice. Only post-baseline scheduled visit data collected prior to discontinuation of trial 
product or initiation of rescue medication will be included in the analysis. This will avoid 
confounding from rescue medication. 
Missing data considerations at week 26
The proportion of missing data i.e. data that do not exist even though subjects are intended to stay in 
the trial regardless of treatment status and initiation of rescue medication(s), when estimating the 
primary estimand , is expected to be maximum 10% based on the oral semaglutide phase 2 trial 
(NN9924-3790). Thus, missing data will be due to withdrawal from trial or lost to follow-up.
The proportion of missing data when estimating the secondary estimand 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 sitagliptin phase 3 trials50 the oral 
semaglutide phase 2 trial (NN9924-3790) and the indication that a low starting dose with gradual 
dose escalation diminishes GI 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 GI AEs and eventually initiation of rescue medication. Initiation of rescue medication is 
expected to be more frequent in the sitagliptin 100 mg 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
The primary endpoint is change from baseline to week 26 in HbA1c. For HbA1c both non-inferiority 
and superiority versus sitagliptin 100 mg are planned to be tested at each dose level. The 
confirmatory secondary endpoint is change from baseline to week 26 in body weight (kg). For body 
weight, superiority versus sitagliptin 100 mg is planned to be tested at each dose level. The sample 
size calculation is based on jointly meeting the below three out of the nine pre-specified 
confirmatory hypotheses shown in Figure 17–1. The closed testing procedure described in Bretz et 
al 201153 is used to control the overall type-1 error at a nominal two-sided 5% level. The three 
hypotheses are
!
HbA1c superiority of oral semaglutide 14 mg vs. sitagliptin 100 mg
!
HbA1c superiority of oral semaglutide 7 mg vs. sitagliptin 100 mg
!
HbA1c non-inferiority of oral semaglutide 3 mg vs. sitagliptin 100 mg (margin 0.3%) 
The statistical testing strategy is based on the following two principles:
!
Within a dose level, glycaemic efficacy must be established by HbA1c non-inferiority before 
testing for added benefits in terms of superiority for HbA1c and/or superiority of body weight. 
!
Glycaemic efficacy by HbA1c non-inferiority 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, gMCP54 using 10000 
simulations. All of the nine pre-specified confirmatory tests are assumed to be independent. Since 
positive correlations among the tests are expected, the assumption of independence is viewed as 
conservative.
The sample size assumptions for treatment effects (TE), adjusted treatment effects and the common 
standard deviation (SD) used across dose levels are given in Table 17–1. These are based on the 
oral semaglutide phase 2 results (NN9924-3790), sitagliptin phase 3a trial results50 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 discontinue trial product or initiate rescue 
medication and for the 10% of subjects with missing data. The treatment effects used in the sample

size calculation will be adjusted according to a 75% smaller effect in these subjects. In addition, the 
non-inferiority margin of 0.3 % for HbA1c is used, when testing for non-inferiority. The adjusted 
treatment effects for testing non-inferiority (HbA1c only) and superiority are as described below:

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 
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”.
Per protocol (PP) analysis set: includes all subjects in the full analysis set who fulfils the 
following criteria
!
have not violated any inclusion criteria
!
have not fulfilled any exclusion criteria
!
have a baseline HbA1cmeasurement
!
is exposed to trial product and have at least one HbA1c measurement at or after week 14
Subjects in the PP analysis set will contribute to the analysis “as treated”.
Before data are locked for statistical analysis and the randomisation code is broken, a review of all 
data will take place. Any decision to exclude either a subject or single observations from the 
statistical analysis is the joint responsibility of the members of the Novo Nordisk study group. 
Exclusion of data from analyses will be used restrictively and normally no subjects will be excluded 
from the FAS. If any subjects or observations are to be excluded from the analysis sets or the 
observation periods defined below, this, together with the reasons for their exclusion, will be 
documented and signed by those responsible before database lock. A description of these exclusions 
will be included in the clinical trial report.
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 (V17) for subjects on trial product
!
the End-of-treatment visit (V16) or the follow-up premature discontinuation visit (V17A), 
whichever comes last, 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.
!
First, subjects will be selected based on the specified analysis set
!
Next, data points on the selected subjects from first step will be selected based on the specified 
observation period

In this trial, three observation periods will be defined, as described below. 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, onset date will be the EAC adjudicated 
onset date.
Definition of the observation periods:
!
In-trial: This observation period will include information assessed at or after date of 
randomisation (as registered in the IWRS system) and up to and including the last direct 
subject-site contact, which is scheduled to take place 5 weeks (+3 days visit window) after the  
planned last dose on trial product at a follow-up visit. For subjects who withdraw their informed 
consent, the in-trial observation period ends at their date of withdrawal. If a subject is lost to 
follow-up, the end of the in-trial period is defined as the date of the last subject-investigator 
contact (site or phone visit). In the case a subject dies during the trial the date of death will be 
the end-date of the in-trial observation period regardless of the above defined end-dates. This 
observation period will be the primary observation period for estimating the primary estimand 
used for evaluating safety.
!
On-treatment: This observation period is a subset of the in-trial observation period and 
represents the time period in which a subject is considered exposed to trial product. For 
adjudicated events, ECGs, anti-semaglutide antibodies and AEs including hypoglycaemic 
episodes information collected on or after the first date of trial product up to and including the 
first date of (i) the follow-up visit V17, (ii) the follow-up prematurely discontinuation visit 
V17A, (iii) the last date on trial product +38 days or (iv) the end-date for the in-trial observation 
period will be used. 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. In addition, the 
ascertainment window includes the follow-up visit window of +3 days after last date on trial 
product. For efficacy and other safety assessments (laboratory assessments, physical 
examination and vital signs) information collected on or after the first date of trial product up to 
and including the last date on trial product +3 days will be used in order to ensure specificity to 
reversible effects of treatment. The end-date for all assessments in the on-treatment observation 
period will be before or the same date as the end-date for the in-trial observation period. This 
observation period will be considered supportive for evaluating efficacy and used for evaluating 
safety. 
!
On-treatment without rescue medication: This observation period is a subset of the on-
treatment observation period. To avoid potential confounding from rescue medications, 
information that is collected after initiation of rescue medication will be excluded from this 
observation period. Specifically, it includes information collected at or after date of first dose on 
trial product up to and including the first date of; (i) last date on trial product +3 days or 
(ii) initiation of rescue medication. Thus, an ascertainment window of 3 days for subjects not 
initiating rescue medication. This observation period will be the primary observation period for 
estimating the secondary estimand.

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). Imputation of missing data at week 26 will be done within 16 groups of subjects 
defined by randomised treatment arm, stratification factor and whether subjects at week 26; (i) have 
discontinued treatment or initiated rescue medication or (ii) 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 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 sitagliptin at week 26:
For each of the 100 (now complete) imputed data sets the change from baseline to week 26 will be 
analysed using an ANCOVA with treatment, stratification factor and region as categorical fixed 
effects and baseline HbA1c as covariate. The results obtained from analysing the datasets will be 
combined using Rubin’s rule55 to draw inference.
From this analysis the estimated treatment differences between each of the oral semaglutide dose 
levels and sitagliptin 100 mg together with associated two-sided 95 % CIs and unadjusted two-sided 
p-values for testing no difference from zero will be presented.
Analysis used for confirming non-inferiority versus sitagliptin at week 26:
Prior to analysing the data using the same model and approach as used for confirming superiority 
(see above) a value of 0.3 % (the non-inferiority margin) will be added to imputed values at week 
26 for the oral semaglutide treatment arms only (Koch 2008)56. For evaluating non-inferiority 
versus sitagliptin 100 mg unadjusted two sided p-values for testing no difference from the non-
inferiority margin 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 observation period. The primary 
analysis for the secondary estimand will be a Mixed Model for Repeated Measurements (MMRM). 
A restricted maximum likelihood (REML) will be used. The model will include all post baseline 
HbA1c measurements collected at scheduled visits up to and including week 26 as dependent 
variables. The independent effects included in the model will be treatment, stratification factor 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. For subjects who have no post-
baseline scheduled assessments available, the baseline value will be carried forward to the first 
scheduled visit to ensure that all randomised subjects will contribute to the statistical analysis.
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. Even if the assumption of MAR is not 
satisfied, this analysis is not expected to bias the estimated HbA1c treatment effect for the secondary 
estimand in favour of oral semaglutide to any important degree. This is supported by the oral 
semaglutide phase 2 results (NN9924-3790) that showed that subjects who discontinue oral 
semaglutide do not have better outcome on average than those who remain on treatment.
Primary hypotheses 
For the primary HbA1c endpoint the following two confirmatory one-sided hypotheses are planned 
to be tested at each dose level of oral semaglutide versus sitagliptin 100 mg. Let the mean treatment 
difference be defined as μ = (oral semaglutide minus sitagliptin 100 mg):
!
Non-inferiority, using a non-inferiority margin of 0.3 %
o
H0: μ ≥0.3 % against Ha: μ < 0.3 %
!
Superiority
o
H0: μ ≥0.0 % against Ha: μ < 0.0 %
Operationally the hypotheses will be evaluated by two-sided tests.
Multiplicity and criteria for confirming hypotheses
The Type-I error for testing the nine confirmatory hypotheses related to the HbA1c and body weight 
endpoints (see Section 17.1) will be preserved in the strong sense at 5 % (two-sided) using the 
weighted Bonferroni-based closed testing procedure described in Bretz et al 201153 and outlined in 
Figure 17–1. The first hypothesis to be tested is non-inferiority 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 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 local significance level (α-local). This process will be 
repeated until no further hypotheses can be confirmed.
Non-inferiority and/or 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 alpha = 0.025) and a one-sided 2.5 % overall significance level in the closed testing 
procedure.
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 recommendations57
and with a report from the US National Research Council58, these analysis will primary evaluate the 
sensitivity of the results due to the impact of missing data. Since conservatism, i.e. avoiding bias in 
favour of semaglutide, depends on the context, separate sensitivity analyses will be made for non-
inferiority and superiority testing.
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, three additional sensitivity analyses for the primary analysis 
will be described that are not based on the pattern mixture model approach.
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
(superiority).
!
A comparator multiple imputation analysis based on FAS using the on-treatment observation 
period (superiority). This sensitivity analysis aims to compare oral semaglutide versus 
sitagliptin 100 mg for subjects who adhere to treatment regardless of whether or not rescue 
medication has been initiated.
!
A comparator multiple imputation analysis differentiating between reasons for discontinuing 
treatment prematurely based on FAS using the in-trial observation period (superiority).
!
A tipping-point multiple imputation analysis based on FAS using the in-trial observation period
(non-inferiority and superiority).
!
A MMRM analysis (the primary for the secondary estimand) based on FAS using the in-trial 
observation period (non-inferiority and superiority).

17.3.3.1
Pattern mixture models
Common for the three pattern mixture model sensitivity analyses is that they all aim to stress-test 
the primary HbA1c results by changing the assumptions for part or all missing data in the oral 
semaglutide treatment arms, while maintaining the missing data assumption for the sitagliptin 100 
mg arm. The analyses will all be implemented using multiple imputation as described for the 
primary analysis of the primary estimand:
!
Comparator multiple imputation analysis: In this sensitivity analysis missing data at week 26 
for all subjects will be imputed to resemble in distribution the week 26 values observed in the 
sitagliptin 100 mg treatment arm. In effect this imputation approach removes the treatment 
difference between oral semaglutide and sitagliptin 100 mg for all subjects randomised to oral 
semaglutide, given that oral semaglutide is better than sitagliptin 100 mg. Due to the potential 
lack of sensitivity for testing non-inferiority this sensitivity analysis will only be used to 
evaluate the robustness of HbA1c superiority conclusions.
!
Comparator multiple imputation analysis differentiating between reasons for discontinuing 
treatment prematurely: In this sensitivity analysis missing data at week 26 for subjects who 
discontinue oral semaglutide treatment due to treatment related AE(s) will be imputed to 
resemble in distribution the week 26 values observed in the sitagliptin 100 mg 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 sitagliptin 100 mg for this selected group of subjects 
randomised to oral semaglutide. This sensitivity analysis is less conservative as compared to the 
first sensitivity analysis. Due to the potential lack of sensitivity for testing non-inferiority this 
sensitivity analysis will only be used to evaluate the robustness of HbA1c superiority 
conclusions.
!
Tipping-point multiple imputation analysis: In this sensitivity analysis, missing data will first be 
imputed according to the primary analysis. Second, 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 reversed. For 
each hypothesis tested the specific value of the penalty that reverses the conclusion will be used

Other sensitivity analysis
The following additional sensitivity analysis will be specified
!
Per-protocol analysis: This sensitivity will be based on the per-protocol analysis set. Data from 
the in-trial observation period will be analysed using the primary analysis approach for the 
primary estimand. This sensitivity analysis will be used to evaluate the robustness of the HbA1c 
non-inferiority conclusions.
!
Complete case analysis: This sensitivity analysis will be based on the on-treatment without 
rescue medication observation period and include subjects in the FAS who have a valid HbA1c 
measurement at week 26. The change from baseline to week 26 in HbA1c will be analysed by a 
linear normal model (ANCOVA) with treatment, stratification factor and region as categorical 
fixed effects and baseline HbA1c as a covariate. This sensitivity analysis will be used to evaluate 
the robustness of the HbA1c non-inferiority conclusions. 
!
Last observation carried forward (LOCF) analysis: This sensitivity analysis will be based on 
the FAS using the on-treatment without rescue medication observation period. The change from 
baseline to week 26 in HbA1c will be analysed by a linear normal model (ANCOVA) with 
treatment, stratification factor and region as categorical fixed effects and baseline HbA1c as a 
covariate. This sensitivity analysis will be used for evaluating the robustness of the HbA1c non-
inferiority and superiority conclusions.
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 and body weight. Due to the large number of sensitivity analyses and their 
inherent conservative nature, it will not be a requirement that all confirmatory hypotheses are 
consistently confirmed across the sensitivity analyses. Thus, no absolute success criteria will be pre-
defined for each sensitivity analysis. The sensitivity results in totality will be used to substantiate 
the credibility of the trial results. 
17.4
Secondary endpoints
17.4.1
Confirmatory secondary endpoints
Change from baseline to week 26 in body weight (kg) will be a confirmatory secondary endpoint. 
The primary and secondary estimands will be estimated using the same approaches as described for 
the primary HbA1c endpoint. Body weight will only be tested for superiority. Baseline body weight 
will be used as a covariate instead of baseline HbA1c in both the imputation and analysis model.

From the analyses the three estimated treatment differences between each of the oral semaglutide 
dose levels and sitagliptin 100 mg will be presented together with associated two-sided 95 % CIs

strictly below its local two-sided significance level resulting from the closed testing procedure in 
Figure 17–1.

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 analysis will be performed separately for week 26, 52 
and 78. For the analysis at week 52 and at week 78, the imputation of missing data will be further 
differentiated by whether subjects have discontinued trial product or initiated rescue medication 
prior to week 26 or at or after week 26. This will result in imputation of missing data within 32 
groups of subjects instead of the 16 groups as described for the week 26 evaluation in 
Section 17.3.1. The frequency of missing data is expected to be slightly larger at week 52 and week 
78 compared to week 26. The rate of missing data is expected to decline over time. 
For evaluation of the secondary estimand the MMRM based primary analysis will include all 
scheduled post-baseline measurement up to and including week 78. From this model the estimated 
treatment differences (ratios) will be presented at week 26 (except for HbA1c and body weight), 52 
and 78 with 95 % confidence intervals and two-sided p-values for test of no difference.
Binary efficacy endpoints
Subjects who after 26 weeks of treatment achieve (yes/no):

!
HbA1c ≤6.5 % (48 mmol/mol) (AACE) target
!
HbA1c reduction ≥1 %

Weight loss ≥3 %

Weight loss ≥5 %
!
Weight loss ≥10 %

HbA1c < 7.0 % (53 mmol/mol) without confirmed hypoglycaemia (treatment emergent severe or 
BG confirmed symptomatic hypoglycaemic episodes) and no weight gain
!
HbA1c reduction ≥1 % and weight loss ≥3 %
The above eight endpoints will be evaluated after week 52 and after week 78 as well.
Handling of missing data for the response status of the above categorical endpoints will be 
determined from the imputed continuous responses. A total of 100 imputed data sets will be created 
based on the same models as used to analyse HbA1c and body weight. For the secondary estimand 
the MMRM based analysis will be implemented in a MI setting. The imputed complete data sets 
will be analysed using a logistic regression model with treatment, stratification factor and region as 
categorical fixed effects and baseline response as covariate (i.e. baseline HbA1c for binary HbA1c 
endpoints, baseline weight for binary weight endpoints and both baseline HbA1c and body weight 
for the binary endpoint that combines both parameters). Inference comparing treatments will be
drawn using Rubin’s rule55.

A treatment emergent hypoglycaemic episode is defined as a hypoglycaemic episode with onset in 
the on-treatment observation period (see definition of observation periods in Section 17.2).
Nocturnal hypoglycaemic episodes: are 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)59. 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 classification33 or BG confirmed by a PG value < 3.1 mmol/L (56 mg/dL) with
symptoms consistent with hypoglycaemia. 
ADA classification33 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).
! 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.
Analysis of severe or BG confirmed symptomatic hypoglycaemic endpoints
The number of treatment emergent severe or BG confirmed symptomatic hypoglycaemic episodes 
will be analysed using a negative binomial regression model with a log-link function and the 
logarithm of the duration of the subject’s on-treatment observation period as offset. The model will 
include factors for treatment, stratification factor and region as fixed factors and baseline HbA1c as 
covariate.
The binary endpoint showing whether a subject has at least one treatment emergent severe or BG

18.1
Benefit-risk assessment of the trial
18.1.1
Risks and precautions
18.1.1.1
Oral Semaglutide
The non-clinical safety programme of oral semaglutide has not revealed any safety issues 
precluding use in humans (see Section 3.1.4).
The sections below describe identified and potential risks associated with oral semaglutide 
treatment. The identified/potential risks are based on findings in non-clinical and clinical trials with 
oral semaglutide as well as other GLP-1 RAs. For each of these risks, mitigating actions have been 
implemented to minimise the risks for subjects enrolled in this trial.
Thyroid C-cell tumours
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 guidance for investigators of further evaluation and action on 
elevated calcitonin concentrations is included in Appendix A. This will ensure appropriate and 
consistent handling of elevated calcitonin levels.
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 intends to become pregnant or are of childbearing potential and not using an adequate 
contraceptive method will not be enrolled in the trial. In addition, throughout the trial, pregnancy 
tests will be done at site visits.
Gastrointestinal adverse events
Consistent with findings with other GLP-1 RAs, the most frequently reported AEs in clinical trials 
with oral semaglutide have been GI disorders (nausea, vomiting, diarrhoea, dyspepsia and 
constipation). Clinical trials have indicated that a low starting dose with gradual dose escalation 
diminishes GI AEs compared with more aggressive dosing regimens. Consequently, a low starting 
dose and gradual dose escalation with 4 weeks between dose-escalation steps have been 
implemented in the trial in order to mitigate GI side effects.

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 occurs.
Hypoglycaemia
Based on current knowledge about the GLP-1 RA drug class, there is a risk of hypoglycaemic 
episodes. Hypoglycaemic episodes have mainly been observed when a GLP-1 RA is combined with 
SU or insulin. The risk for development of hypoglycaemia with oral semaglutide in combination 
with SU and insulin is unknown due to limited data. In this trial subjects can be on anti-diabetic 
background medication with SU, but not insulin (however, if rescue medication is needed insulin 
can be prescribed as add-on to randomised treatment). If a subject on SU develops unacceptable 
hypoglycaemia the dose of SU can be reduced.
Acute renal impairment
In subjects treated with GLP-1 RAs including oral semaglutide GI AEs such as nausea, vomiting 
and diarrhoea may lead to significant dehydration and secondary acute renal impairment. Subjects 
with adverse GI events should be recommended to drink plenty of fluids in order to avoid 
dehydration. Also serum creatinine and urea will be measured throughout the trial and eGFR will be 
calculated.
Impaired renal function may increase the risk of metformin associated lactic acidosis when GLP-1 
RAs are co-administered with metformin. As a precaution serum creatinine will be measured 
regularly. In subjects treated with metformin who experience prolonged or severe nausea and 
vomiting, the investigator should monitor serum creatinine and if clinically indicated, withhold 
metformin until resolution of the renal dysfunction.
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 measured throughout the trial.
General precautions 
All subjects will be included after a thorough evaluation in 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

Diabetes25,26 (excluding GLP-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 2014 Standards of Medical Care in Diabetes60.
18.1.1.2
Sitagliptin
The most commonly reported side effects are upper respiratory tract infection, nasopharyngitis and 
headache. Also acute pancreatitis, acute renal failure, hypersensitivity reactions and hypoglycaemia 
have been reported50. 
18.1.2
Benefits 
In this trial subjects will be randomised to one of four treatment arms involving a treatment regimen 
anticipated to be more efficacious than the treatment they receive at the time of entry into the trial. 
Based on the results of the phase 2 dose finding trial oral semaglutide is expected to provide 
clinically significant improvements in glycaemic control and body weight. 
Similarly treatment with sitagliptin is expected to provide clinically significant improvements in 
glycaemic control50.
In addition, it is expected that all subjects 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. 
18.1.3
Risk and benefit conclusion 
The safety profile of oral semaglutide generated from the non-clinical and clinical development 
programme has not revealed any safety issues that would prohibit administration of doses in 
accordance with the planned clinical trial. The phase 2 results indicate that oral semaglutide will 
provide clinically significant improvements in glycaemic control and body weight. Sitagliptin is 
already a marketed drug approved for the use in subjects with T2DM. In conclusion, the potential 
risk to the subjects in this trial is considered low and acceptable in view of the anticipated benefits 
oral semaglutide/sitagliptin 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.

22 Responsibilities
The investigator is accountable for the conduct of the trial at his/her 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 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 must ensure adequate supervision of the conduct of the trial at the trial site. 
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 should 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.
One or 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 
investigator(s) will be appointed based upon the criteria defined by the International Committee of 
Medical Journal Editors for research publications61.
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 Disclosure4.
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 Editors61 (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 biospecimens
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 as long as the 
product is on the market plus 20 years. 
The files from the trial site/institution must be retained for 15 years after the completion of the trial, 
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 biospecimens
Antibody samples may be stored at the special laboratory until market authorisation in case Health 
Authorities requests further characterisation of the antibody response (maximum up to 15 years 
from end of trial).
Semaglutide PK samples will be stored at the specialised laboratory until final CTR in case Novo 
Nordisk request further analysis of the PK samples.
None of the data will be identified by name. Antibody samples and semaglutide PK samples will be 
identified only by a subject number, a visit number and a trial identification number. The trial staff 
is responsible for maintaining a code list which links to the subject number. The code list must be 
kept for at least 15 years. The code list may be reviewed by Novo Nordisk staff including auditors

or representatives from regulatory authorities, but Novo Nordisk staff will not make any copies of 
this list if names are included.
In the event that the blood samples collected for antibody analysis will be used in the future, the 
investigator will become directly informed by Novo Nordisk about the results if the findings are 
deemed clinically relevant. In such case, a written summary of the findings, including listings of 
subject specific values, will be provided once a firm conclusion from the results has been drawn by 
Novo Nordisk. Subjects may at any time contact the investigator if they wish to be informed about 
results derived from stored antibody samples obtained from their own body.

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

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 disease.1 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 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 conclusions.2,3

Introduction including rationale for the protocol amendment
In addition to the below, minor inconsistencies and errors have been corrected.
1.1
Section 2 Flowchart
In the flowchart the timing of visit 16A (V16A) and the visit window of +3 days has been added for 
clarity. 
An ‘x’ at visit 2 (Randomisation) for drug accountability has been added as the site should enter the 
date of dispensing the trial product in the interactive web response system (IWRS).
1.2
Section 4.2.2.2 Supportive secondary endpoints
Time to rescue medication will only be analysed at the end of the trial and the text describing 
different time points for assessment has  been deleted.
1.3
Section 8.1.5 Premature discontinuation of trial product and Follow-up (visits 16A 
and 17A)
The timing of V16A and visit window of +3 days has been added for clarity. 
1.4
Section 8.4.4 Electrocardiogram – 12 -lead
A confirmatory ECG is required for all post-baseline ECGs suggestive of a new myocardial 
infarction (MI), as assessed by the central ECG reader. The rationale for this confirmatory ECG is 
to confirm that the ECG findings suggestive of a new MI are valid.
1.5
Section 8.4.7 Antibodies
Anti-semaglutide neutralising antibodies has been changed to anti-semaglutide binding antibodies
in Section 8.4.7 as it does not make sense to characterise neutralising antibodies for neutralising 
effect, however, it does make sense to characterise binding antibodies for neutralising effect. 
Binding antibodies should be seen as all antibodies binding to the drug (semaglutide), a fraction of 
these antibodies may be neutralising.
1.6
Sections 8.7.4 Assessments in case of increased levels of aminotransferases, 12.1
definitions, Appendix B Section 1 Adverse Events requiring additional data collection 
and Appendix B Section 1.13 Hepatotoxicity events
The cut off level for repeat testing of increased levels of aminotransferases has been updated from 
ALT/AST >10x UNL to >5x UNL in section 8.7.4. The rationale is to prompt follow-up of potential 
clinical significant aminotransferase levels.

Definition of elevated liver enzymes to be reported as adverse events (AEs) requiring additional 
data collection has been updated in section 12.1 and appendix B to align with 8.7.4 and ensure that 
all potential hepatotoxicity events are captured and can be assessed appropriately.
Suspicion of transmission of infectious agents via the trial product and events fulfilling Hy’s law 
are included underneath the defined seriousness criteria in section 12.1 to clarify that these are 
specific AEs that always fulfil the seriousness criteria. 
The definition of Hy’s law in section 12.1 has been updated to align with the FDA guidance 
document “Guidance for Industry Drug-Induced Liver Injury: Premarketing Clinical Evaluation”.
1.7
Section 9.4 Drug accountability and destruction
To ensure proper trial product accountability sites are requested to account for non-allocated trial 
product as well.
1.8
Section 12.2 Reporting of adverse events
Figure 12-1 has been updated as the previous AE flow did not contain the full AE process flow as 
described in the protocol text.
1.9
Sections 17 Statistical considerations, 17.3.1 Primary analysis for the primary 
estimand, 17.4.2.1 Efficacy endpoints and 17.4.2.2 Safety endpoints
The text regarding stratification factors in the statistical section 17 has been updated to make it
more clear how these are included in the statistical analyses.
Two wrong units have been corrected and irrelevant data removed from Table 17.1.
For the primary analysis to the primary estimand, missing data will not be imputed based on the 
stratification factor, but only treatment and treatment adherence/rescue status  i.e. 16 groups are 
change to 8 groups. In the analysis after 52 weeks 32 groups has been changed to 16 due to the 
same decision. The stratification factor has instead been added as a categorical fixed effect in the 
ANCOVA analysis.
The text below the time to event endpoint has been removed from the statistical section as well, 
since the endpoint will only be analysed at the end of the trial.
In Section 17.4.2.2 treatment emergent hypoglycaemic events are defined twice by mistake, thus the 
second paragraph on the definition is deleted.

2.4
Section 8.4.4 Electrocardiogram – 12 – Lead
12-lead ECGs will be performed as per flowchart (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 myocardial infarction 
(MI), the investigator will be notified and a confirmatory ECG should be performed., uUnless
already done, the investigator should report this as AE or SAE at investigator’s discretion (see 
Section 12.1).

For some of the analyses described in Section 8.7.1 and 8.7.1 8.7.2 a local laboratory must be used.
2.7
Section 8.7.4 Assessments in case of increased levels of aminotransferases
In case of
1. ALT or AST >3x UNL and total bilirubin >2x UNL,
the event must be reported as an SAE (see Section 12.1). 
2. ALT or AST >105x UNL and total bilirubin ≤2x UNL, 
the event should be reported as an AE requiring additional data collection (see Section 12.1 and 
Appendix B).
For both events prompt repeat testing (at central laboratory) including ALT, AST, ALP and total 
bilirubin should be done and discontinuation of trial product considered. 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.
2.8
Section 9.4 Drug accountability and destruction
Drug accountability is the responsibility of the investigator.
Subjects must be instructed to return all used, partly used and unused trial products including empty 
packaging material at each dispensing visit.
Returned trial product (used/partly used or unused including empty packaging material) can be 
stored at room temperature and must be stored separately from non-allocated trial product. Non-
allocated trial product (expired, damaged and available) must be accounted as unused at the latest 
at closure of the trial site.
Drug accountability is performed by using the IWRS. Only dispensed DUNs returned by the subject 
(used/partly used or unused) are accounted for. Drug accountability should be done on tablet level.

Serious adverse event
An 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.
!

prevent one of the outcomes listed in the definition of SAEd. 
Suspicion of transmission of infectious agents via the trial product must always be 
considered an SAE. 
[…]
Trial specific serious adverse event
The following laboratory abnormalities must be reported as an SAE:
!
ALT or AST >3x UNL and total bilirubin >2x UNL
Additional assessments should be made for events meeting the above criterion (see Section 8.7.4).

Section 17 Statistical considerations
General considerations
[…]
The randomisation is stratified based on pre-trial therapy at screening (metformin or 
metformin+SU) and descent (Japanese subjects/non-Japanese subjects). In the statistical analyses 
descent is a part of region and pre-trial therapy at screening is referred to as stratification factor.
In statistical analyses where stratification is included,tThe two combinations (metformin;
metformin+SU) in the stratification factor will be included based on the actual information
collected through the eCRF. In case of missing eCRF information the information collected from 
IWRS system will be used.

Section 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). Imputation of missing data at week 26 will be done within 16 8 groups of subjects
defined by randomised treatment arm, stratification factor and whether subjects at week 26; (i) have
discontinued treatment or initiated rescue medication or (ii) 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 status.
Missing values for each group will be imputed as follows:
!
An analysis of covariance (ANCOVA) with region and stratification factor as a categorical 
fixed effects and baseline HbA1c measurement as a covariate will be fitted to observed 
values of the change from baseline in HbA1c at week 26.
!
The estimated parameters for location and dispersion will be used to impute 100 values for 
each subject with missing week 26 data based on region, stratification factor and baseline 
HbA1c. Thus, 100 complete data sets will be generated including observed and imputed 
values.
Analysis used for confirming superiority versus sitagliptin at week 26:
For each of the 100 (now complete) imputed data sets the change from baseline to week 26 will be
analysed using an ANCOVA with treatment, region and stratification factor as categorical fixed 
effects and baseline HbA1c as covariate. The results obtained from analysing the datasets will be 
combined using Rubin’s rule to draw inference.
2.13
Section 17.4.2.1 Efficacy endpoints
[…]
For evaluation of the primary estimand the analysis will be performed separately for week 26, 52
and 78. For the analysis at week 52 and at week 78, the imputation of missing data will be further
differentiated by whether subjects have discontinued trial product or initiated rescue medication
prior to week 26 or at or after week 26. This will result in imputation of missing data within 16 32  
groups of subjects instead of the 16 8 groups as described for the week 26 evaluation in
Section 17.3.1. The frequency of missing data is expected to be slightly larger at week 52 and week
78 compared to week 26. The rate of missing data is expected to decline over time.

Subjects completing the study without need for rescue medication will be censored at the time point
of actual date of last trial product. Start time is date of first trial product. Time to rescue medication
will be described and compared for each of the oral semaglutide dose level versus sitagliptin 100
mg using likelihood ratio tests obtained from a proportional Cox hazards model. From this analysis
the estimated Hazard ratios between each dose levels and sitagliptin will be presented together with
95 % confidence intervals and two-sided p-values for test of no difference. This endpoint will be
evaluated after week 26, after week 52 and after week 78. Furthermore, the endpoint will be 
presented by a Kaplan-Meier plot.

Treatment emergent: hypoglycaemic episode 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).
A treatment emergent hypoglycaemic episode is defined as a hypoglycaemic episode with onset in 
the on-treatment observation period (see definition of observation periods in Section 17.2).

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 
Protocol sections updated: 2, 4.2.2.2, 8.4.3, 12.1, 12.2, 17.2, 17.4.2.2, 18.1.1.1, 27; Appendix B 
section 1 and 1.14 (new).
Transient worsening of diabetic retinopathy is a recognised complication in selected patients with 
diabetes after initiation of intensive antidiabetic treatment1-3. 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. As recruitment has been completed, the information will be collected for all 
subjects retrospectively as well as going forward, 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
Protocol sections updated: 8.4.1, 18.1.1.1, 27.
, 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
Protocol sections updated: 6.6, 8.1, 8.1.4, 8.1.5, 8.1.6.1 (new).
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
Laboratory analysis
Protocol sections updated: 8.4.7, 8.5, 8.7.1.
The protocol is updated to reflect that on suspicion of acute pancreatitis the investigator has the 
option of performing measurement of lipase and amylase not only via local laboratory but also via 
central lab in accordance with the specific clinical situation.
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.
Statistical considerations
Protocol sections updated: 17.3.1, 17.4.2.1.
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. Furthermore, the description of the 
Cox hazard model used for the time to event endpoint has been clarified.
Adverse events for Adjudication
Protocol sections updated: 12.7.2.
Table 12-2 has been aligned with Table 12-1 reflecting that unstable angina pectoris (UAP) requires
hospitalisation to qualify for Event Adjudication.

which is now interpreted as “less than”.
Background medication
Protocol sections updated: 5.3.2.
Section has been updated to specify that dose changes of background medication is allowed in case 
of a safety concern.
Rescue criteria
Protocol sections updated: 6.4.
The section has been updated to specify that rescue medication should be offered until end of 
treatment and not end of trial as previously specified. After end of treatment, the protocol section 
5.4 applies.

2.3
Section 5.3.2
Background medication
After inclusion (V1), subjects must continue anti-diabetic pre-trial background medication (i.e. 
metformin alone or in combination with SU) throughout the entire trial. The background medication 
must be maintained at the stable, pre-trial dose and at the same frequency during the whole 
treatment period unless rescue medication is needed (see Section 6.4),or if the subject has 
unacceptable hypoglycaemia on a background of SU in which case the dose of SU can be reduced 
or if another safety concern related to the background medication arises.
2.4
Section 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 central laboratory) should be obtained by 
calling the subject for a re-test:
!
14.4 mmol/L (260 mg/dL) from week 8 to end of week 13
!
13.3 mmol/L (240 mg/dL) from week 14 to end of week 25
!
11.1 mmol/L (200 mg/dL) from week 26 to end of trialtreatment 
If the confirmatory FPG also exceeds the values described above, the subject should be offered 
rescue medication (i.e. intensification of existing anti-diabetic background medication and/or 
initiation of new anti-diabetic medication). 
In addition, subject should be offered rescue medication if:
!
HbA1c (at central laboratory) > 8.5% (69.4 mmol/mol) from week 26 to end of trialtreatment
2.5
Section 6.6
Withdrawal criteria
The subject may withdraw consent at will at any time. The subject’s request to withdraw from the 
trial must always be respected.
A subject who does not complete the trial is also considered withdrawn from the trial. Hence, a 
subject is considered withdrawn from trial if the following applies:
!
Subject withdrew consent
!
Subject is lost to follow up (only to be used if there is no contact with the subject by the time of 
the subject’s last scheduled visit, see Sections 8.1.4 - 8.1.6.1)
!
Other (subject deceased or closure of trial site)

Section 8.1
Visit procedures
[…]
If a subject is unable or unwilling to attend all subsequent visit(s) the investigator should at least 
aim to have the subject attend the V8, V12 and the End-of-treatment visit (V16) as these visits 
should be performed for all subjects (except subjects who withdraw informed consent, see 
Section 8.1.6).
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.
2.7
Section 8.1.4
End-of-treatment (visit 16) and Follow-up (visit 17)
At V16 the subject should be reminded about the importance of attending the follow-up visit (V17). 
If the subject, nonetheless, does not attend V17, 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 are in contact with the site, at the subject’s 
last scheduled visit. For subjects who complete treatment, the last scheduled visit is V17. (For 
subjects who discontinue trial product, see Section 8.1.5).
In case the subject cannot be reached (by clinic visit or phone contact) at the scheduled visit 17 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) to collect health status. If no health status can be collected, the subject should be 
considered lost to follow.
2.8
Section 8.1.5
Premature discontinuation of trial product and follow-up (visits 16A 
and 17A)
Subjects who discontinue trial product prematurely should attend visit 16A, scheduled to take place 
after discontinuation of trial product (+3 days visit window). Visit 17A should be scheduled 5 
weeks (+3 days visit window) after the last date on trial product. A treatment discontinuation 
session must be performed in the IWRS at visit 16A (see Section 10).
Subjects should continue with the originally scheduled site contacts after visit 17A and up to and 
including visit 16. If necessary, in order to retain the subject in the trial, site visits can be replaced 
by phone contacts after V17A. However, as a minimum, these subjects should be asked to attend 
the scheduled V8 at week 26, V12 at week 52 and End-of-treatment (V16) at week 78. if a subject 
is unable or unwilling to attend all subsequent visit(s), the investigator should at least aim to have 
the subject attend V8 (week 26), V12 (week 52) and End-of-treatment (V16) (week 78) as these

visits should be performed for all subjects, if at all possible (except subjects who withdraw consent, 
see Section 8.1.6). 
In case the subject cannot be reached (by clinic visit or phone contact) at the scheduled visit 17 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) to collect health status. If no health status can be collected, the subject should be 
considered lost to follow up. 
A subject who prematurely discontinues 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 V16 (or V17A if it 
is scheduled after V16). (For subjects completing treatment, see Section 8.1.4). The site should in 
due time prepare for establishing contact with the subject within the visit window of the scheduled 
V8, V12 and V16 respectively, if the subject has agreed to attend these visits.
2.9
Section 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: V17 for subjects who have completed treatment, whereas for subjects who have discontinued 
trial product prematurely the last scheduled visit is V16 (or V17A if it is scheduled after V16). Only 
if contact with the subject is not regained by the end of the visit window of the subject’s last 
scheduled visit, can the subject be considered lost to follow up (see Section 6.6).

Section 17.2
Definition of analysis sets
On-treatment: This observation period is a subset of the in-trial observation period and represents 
the time period in which a subject is considered exposed to trial product. For adjudicated events, 
ECGs, eye examination category, anti-semaglutide antibodies and AEs including hypoglycaemic 
episodes information collected on or after the first date of trial product up to and including the first 
date of (i) the follow-up visit V17, (ii) the follow-up prematurely discontinuation visit V17A, (iii) 
the last date on trial product +38 days or (iv) the end-date for the in-trial observation period will be 
used.
2.19
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, stratification factor as categorical fixed 
effects and baseline HbA1c measurement as a covariate will be fitted to observed values of 
the change from baseline in HbA1c at week 26.
!
The estimated parameters for location and dispersion will be used to impute 100 1000 values 
for each subject with missing week 26 data based on region, stratification factor 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, stratification factor and region as 
categorical fixed effects and baseline HbA1c as covariate. The results obtained from analysing the 
datasets will be combined using Rubin’s rule55 to draw inference.
2.20
Section 17.4.2.1
Efficacy endpoints
Continuous efficacy endpoints 
[…]
For evaluation of the primary estimand the analysis will be performed separately for week 26, 52 
and week 78. For the analysis at week 52 and at week 78, the imputation of missing data will be 
further differentiated by whether subjects have discontinued trial product or initiated rescue 
medication prior to week 26 or at/or after week 26. This will result in imputation of missing data 
within 1612 groups of subjects instead of the 8 groups as described for the week 26 evaluation in 
Section 17.3.1. If less than five subjects have available data in one of the 12 groups, the imputation 
will be made within the 8 groups specified for the primary evaluation. The frequency of missing 
data is expected to be slightly larger at week 52 and week 78 compared to week 26. The rate of 
missing data is expected to decline over time.

Handling of missing data for the response status of the above categorical endpoints will be 
determined from the imputed continuous responses. A total of 1001000 imputed data sets will be 
created based on the same models as used to analyse HbA1c and body weight. For the secondary 
estimand the MMRM based analysis will be implemented in a MI setting. The imputed complete 
data sets will be analysed using a logistic regression model with treatment, stratification factor and 
region as categorical fixed effects and baseline response as covariate (i.e. baseline HbA1c for binary 
HbA1c endpoints, baseline weight for binary weight endpoints and both baseline HbA1c and body 
weight for the binary endpoint that combines both parameters). Inference comparing treatments will 
be drawn using Rubin’s rule55.

Time to rescue medication
Subjects completing the study without need for rescue medication will be censored at the time point 
of actual date of last trial product. Start time is date of first trial product. Time to rescue medication 
will be described and compared for each of the oral semaglutide dose level versus sitagliptin 100 
mg using likelihood ratio tests obtained from a proportional Cox hazards model with treatment, 
stratification factor and region as categorical fixed effects and baseline HbA1c as a covariate. From 
this analysis the estimated Hazard ratios between each dose levels and sitagliptin will be presented 
together with 95 % confidence intervals and two-sided p-values for test of no difference. 
Furthermore, the endpoint will be presented by a Kaplan-Meier plot.

Section 18.1.1.1
Oral Semaglutide
Diabetic retinopathy complications
A transient worsening of diabetic retinopathy is a recognised complication in selected patients with 
diabetes after initiation of intensive antidiabetic treatment63-65. 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 progression66,67even in intensively treated patients who experienced early worsening64. 
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 placebo68. 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 trial69.
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 
Diabetes25,26 (excluding GLP-1 RAs, DPP-4 inhibitors, amylin analogues and SGLT-2 inhibitors). 
It is the responsibility of the investigator to ensure the best possible care 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 retinopathy69.
