Summary
Objectives and endpoints:
Primary objective
To compare the safety and tolerability of once-daily dosing of three dose levels (3, 7 and 14 mg) of 
oral semaglutide versus once-weekly 0.75 mg dulaglutide subcutaneously both in combination with 
one oral anti-diabetic drug (sulphonylurea, glinide, thiazolidinedione, alpha-glucosidase inhibitor or 
sodium-glucose cotransporter-2 inhibitor) in Japanese subjects with type 2 diabetes mellitus.
Secondary objective
To compare the effect of once-daily dosing of three dose levels (3, 7 and 14 mg) of oral semaglutide 
versus once-weekly 0.75 mg dulaglutide subcutaneously both in combination with one oral anti-
diabetic drug (sulphonylurea, glinide, thiazolidinedione, alpha-glucosidase inhibitor or sodium-
glucose cotransporter-2 inhibitor) on glycaemic control and body weight in Japanese subjects with 
type 2 diabetes mellitus.
Primary endpoint
Number of treatment-emergent adverse events during exposure to trial product, assessed up to 
approximately 57 weeks
Key secondary endpoints
Number of treatment-emergent severe or blood glucose-confirmed symptomatic hypoglycaemic 
episodes during exposure to trial product, assessed up to approximately 57 weeks
Change from baseline to week 26 and 52 in:

Body weight (kg)
Trial design:
This is a 52-week, randomised, open-label, active-controlled, parallel-group, multi-centre, single 
country trial with 4 treatment arms.
Japanese subjects with type 2 diabetes mellitus inadequately controlled on one oral anti-diabetic 
drug (OAD) will be randomised in a 2:2:2:1 manner to receive one of the following treatments as 
add-on to their pre-trial background OAD medication:
!
Oral semaglutide 3 mg once-daily
!
Oral semaglutide 7 mg once-daily
!
Oral semaglutide 14 mg once-daily 
!
Dulaglutide 0.75 mg s.c. once-weekly

The background OAD medication must consist of one of sulphonylurea (SU), glinide, 
thiazolidinedione (TZD), alpha-glucosidase inhibitor (α-GI) or sodium-glucose cotransporter-2
(SGLT-2) inhibitor as monotherapy.
Total trial duration for the individual subject will be approximately 59 weeks. The trial includes a 2-
week screening period and a 52-week randomised treatment period, followed by a 5-week follow-
up period. 
Trial population:
Number of subjects planned to be randomised: 455
Inclusion criteria
!
Informed consent obtained before any trial-related activities. Trial-related activities are any 
procedures that are carried out as part of the trial, including activities to determine suitability for 
the trial.
!

Description
a
Screening assessments should be performed up to 2 weeks prior to randomisation and the subject can be randomised as soon as all inclusion and exclusion 
criteria are confirmed. The screening assessment must not exceed 3 weeks prior to randomisation (V2).
b
The follow-up visit (V14) should be scheduled 5 weeks after the last date on trial product (+3 days visit window).
Subjects, who have discontinued trial product prematurely, are not required to attend V14.
c
V13A and V14A are only applicable for subjects who have discontinued trial product prematurely
d
Fundus photography/dilated fundoscopy performed within 90 days prior to randomisation is acceptable if results are available for evaluation at V2, unless 
worsening of visual function since last examination. Fundus photography/dilated fundoscopy for V13 is allowed to be performed between V12 and V13 
(preferably as close to V13 as possible).
e
For women of child-bearing potential: Urine pregnancy test should also be performed at any time during the trial if a menstrual period is missed.
f
At V1, only ALT, creatinine and eGFR will be assessed as part of Biochemistry.
g
Adverse events reporting includes events from the first trial-related activity after the subject has signed the informed consent, however, pre-existing 
conditions identified as a result of the screening procedures should be reported as medical history or concomitant illness.
h
Fasting for blood sampling is defined as no food or liquid within the last 8 hours prior to blood sampling, however, water is allowed up until 2 hours prior 
to blood sampling. Trial product must be taken after blood sampling (see Section 8.1.2 for detail, including reminders for any other antidiabetic 
medication).
i
The investigator must document that direction for use is given to the subject verbally and in writing at the first dispensing visit (V2). Directions for use 
should be given to the subject at subsequent visits when judged necessary by the investigator. 
The subjects allocated to dulaglutide must be trained in how to handle the pre-filled pen when handed out the first time and at subsequent visits when 
judged necessary by the investigator.

Background information and rationale for the trial
The trial will be conducted in compliance with this protocol, International Conference on 
Harmonisation (ICH) Good Clinical Practice (GCP)1 and applicable regulatory requirements, and in 
accordance with the Declaration of Helsinki2. 
In this document, the term investigator refers to the individual responsible for the overall conduct of 
the clinical trial at a trial site.
3.1
Background information
For an assessment of benefits and risks of the trial, see Section 18.1.
3.1.1
Type 2 diabetes mellitus 
Type 2 diabetes mellitus (T2DM) is a progressive metabolic disease primarily characterised by 
abnormal glucose metabolism. The pathogenesis is heterogeneous involving environmental, 
lifestyle and genetic factors leading to chronic hyperglycaemia caused by peripheral tissue insulin 
resistance, impaired insulin secretion due to abnormal beta-cell function and abnormal glucose 
metabolism in the liver3.
Optimal glycaemic control is the treatment goal in subjects with T2DM in order to prevent long-
term complications associated with chronic hyperglycaemia4. Despite the availability of several 
anti-diabetic drugs, a significant proportion of subjects with T2DM do not achieve the 
recommended targets for glycaemic control5,6.
3.1.2
Glucagon-like peptide-1
Glucagon-like peptide-1 (GLP-1) is an incretin hormone with a glucose-dependent stimulatory 
effect on insulin and inhibitory effect on glucagon secretion from the pancreatic islets7,8. Subjects 
with T2DM have a decreased incretin effect9,10,11,12. However, the insulinotropic action of GLP-1 
and thus, the ability to lower blood glucose (BG) levels, is preserved when GLP-1 is administered at 
supraphysiological levels13. In addition, supraphysiological levels of GLP-1 induce reduction in 
body weight14. GLP-1 is a physiological regulator of appetite and food intake and GLP-1 receptors 
are present in several areas of the brain involved in appetite regulation15,16. Physiologically, GLP-1 
also has a pronounced inhibitory effect on gastric emptying; however this effect seems to diminish 
upon chronic exposure14,15,16. These mechanisms of action make GLP-1RA an attractive 
pharmacological treatment for T2DM17,18,19.
3.1.3
Oral semaglutide
Semaglutide is a long-acting GLP-1 RA structurally similar to liraglutide (Victoza®), a once-daily 
GLP-1 RA developed by Novo Nordisk and approved worldwide for the treatment of T2DM. 
Compared to human native GLP-1, which has a short half-life, the semaglutide molecule has three 
minor but important modifications ensuring protraction of its action: amino acid substitutions at

position 8 (alanine to alpha-aminoisobutyric acid, a synthetic amino acid) and position 34 (lysine to 
arginine) and acylation of the peptide backbone with a spacer and C-18 fatty di-acid chain to lysine 
in position 2620,21. The fatty di-acid side chain and the spacer mediate strong binding to albumin, 
thereby reducing renal clearance. The amino acid substitution at position 8 makes semaglutide less 
susceptible to degradation by dipeptidyl peptidase-4 (DPP-4). The change in position 34 from a 
lysine to an arginine is included to have only one lysine in the sequence where to a spacer can be 
attached.
Semaglutide is in development for oral once-daily treatment of T2DM. As the bioavailability of 
GLP-1 RAs is low when administered orally, semaglutide has been co-formulated with the 
absorption-enhancing excipient sodium N-[8-(2-hydroxybenzoyl) amino] caprylate (SNAC) to 
increase the bioavailability of semaglutide. The absorption-enhancing properties of SNAC co-
formulation are based on the
concept developed by 
SNAC facilitates the absorption of semaglutide in a strictly time and size dependent manner, 
primarily via the transcellular route. The available data for semaglutide co-formulated with SNAC 
support that the absorption takes place in the stomach in a localised, buffered environment in close 
proximity to the tablet erosion. The absorption process is hampered if dosed with food, liquid or in 
the presence of significant stomach content. 
The absorption enhancement requires co-formulation between semaglutide and SNAC. Throughout 
this document “oral semaglutide” will refer to the drug product, that is, semaglutide co-formulated 
with 300 mg SNAC. 
3.1.4
Nonclinical data
3.1.4.1
Semaglutide
The nonclinical programme for semaglutide was designed according to the ICH M3 guideline to 
support the clinical development22. The standard nonclinical data package required to support phase 
3 clinical trials has been completed. In addition, 2-year carcinogenicity studies and a pre- and 
postnatal development toxicity study have been completed. Semaglutide was generally well 
tolerated in animals (mice, rats and cynomolgus monkeys). Two potential safety issues have been 
identified and these are detailed below.
Thyroid C-cell tumours in rodents
Treatment-related non-genotoxic proliferative changes in the thyroid C-cells of mice and rats were 
observed in 2-year carcinogenicity studies with semaglutide; thyroid hyperplasia was preceded by 
an increase in serum calcitonin. C-cell changes have not been observed in long-term studies in non-
human primate. The observed pattern of effects in mice and rats and lack of these effects in the non-
human primate and in man suggest that the mechanism by which semaglutide acts on the thyroid C-
cells in rodents is the same as has been demonstrated for other GLP-1 RAs, including liraglutide.

According to this mechanism, C-cell hyperplasia is mediated by the GLP-1 receptor and is not 
associated with RET (re-arranged during transfection) gene activation and rodents appear to be 
particularly sensitive, whereas humans are not. The relevance for human subjects is currently 
unknown, but considered to be low23.
Embryo−foetal development toxicity
Semaglutide caused embryo-foetal development toxicity in the rat through a GLP-1 receptor 
mediated effect on the inverted yolk sac placenta leading to impaired nutrient supply to the 
developing embryo. Primates do not have an inverted yolk sac placenta which makes this 
mechanism unlikely to be of relevance to humans and cynomolgus monkeys. In the developmental 
toxicity studies in cynomolgus monkey, a marked maternal body weight loss associated with the 
pharmacological effect of semaglutide coincided with increased early foetal loss; however, there 
was no indication of a teratogenic potential of semaglutide in this species.
A review of the results from the nonclinical studies can be found in the investigator’s brochure (IB) 
for semaglutide (subcutaneous administration), edition 1124 and the IB for oral administration of 
semaglutide (NN9924), edition 725, or any updates of these documents.
3.1.4.2
SNAC
SNAC was developed as an absorption-enhancing excipient for the oral route of administration. The 
nonclinical programme to support clinical phase 3 development and marketing authorisation 
application submission has been conducted including a 26-week carcinogenicity study in transgenic 
rasH2 mice and a 2-year carcinogenicity study in Sprague-Dawley rats.
 
 
 
 
 
 Measurements of lactate levels have 
been included at selected time points around peak concentrations of SNAC in two of the phase 3a 
trials in the PIONEER programme (PIONEER 1 and 2) with the intention to document that SNAC 
does not impair cellular respiration in humans. In addition, events of lactic acidosis must be 
reported as an adverse event(AE)requiring additional data collection, please refer to Section 
8.4.1.2, Section 12.1.5and appendix B.
The carcinogenicity studies demonstrated that SNAC was not carcinogenic to the transgenic rasH2 
mouse or the Sprague-Dawley rat. The doses tested coveredtotal exposures of SNAC in plasma (in

terms of AUC) of 2-fold in the mouse and up to 44-fold in the rat when compared to the mean total 
exposure of SNAC in humans following a clinical dose of 300 mg SNAC/day.
A review of the SNAC results from the nonclinical studies can be found in the IB for oral 
administration of semaglutide (NN9924), edition 725 or any updates hereof.
3.1.5
Clinical data for oral semaglutide
A comprehensive clinical pharmacology programme including 12 trials has been completed, as well 
as a 26-week phase 2 dose-finding trial involving more than 600 subjects with T2DM.
For details on the individual trials, please see the IB for oral administration of semaglutide 
(NN9924) edition 725, or any updates hereof.
3.1.5.1
Pharmacokinetics
In the multiple-dose trial (NN9924-3991), oral semaglutide has demonstrated a long mean terminal 
half-life (t½) ranging from 153 to 161 hours (~1 week) and a median time to reach maximum 
observed concentration (tmax) ranging from 1 to 2 hours in healthy subjects. 
In multiple-dose pharmacokinetics (PK) trials, the exposure to oral semaglutide increased with 
increasing dose. Overall, the pharmacokinetic properties of semaglutide appeared similar in healthy 
subjects and in subjects with T2DM.
Exposure to semaglutide exhibits a substantially greater dose-to-dose variation following oral 
administration compared to subcutaneous (s.c.) administration. However, when administered orally 
once-daily the PK properties of semaglutide, i.e. low clearance and long half-life, will limit the 
variation in exposure at steady state.
Data obtained following investigation of different dosing conditions for oral semaglutide have 
demonstrated that subjects should take the oral semaglutide tablet in the morning in a fasting state 
and at least 30 minutes before the first meal of the day.

In subjects with mild to severe hepatic impairment, the exposure to semaglutide appeared to be 
unaffected by the degree of hepatic impairment, whereas the exposure to SNAC (in terms of both 
AUC and Cmax) was increased for subjects with hepatic impairment as compared to subjects with 
normal hepatic function.
All tablets of oral semaglutide contain 300 mg of SNAC regardless of the semaglutide dose. SNAC 
is rapidly absorbed with a median tmax ranging from 0.35−0.5 hours in healthy subjects and from 
0.52−1.43 hours in subjects with T2DM. It is extensively metabolised and no accumulation of 
SNAC has been observed in clinical trials. 
3.1.5.2
Efficacy
The efficacy of oral semaglutide in adult subjects with T2DM was investigated in a 26-week phase 
2 dose-finding trial (NN9924-3790). In this trial, placebo or one of the following doses of oral 
semaglutide were administered once daily: 2.5, 5, 10, 20 and 40 mg.
Results from the trial showed that oral semaglutide effectively lowered glycosylated haemoglobin 
(HbA1c) and body weight. Placebo-adjusted reductions in HbA1c were dose-dependent and 
statistically significant for all oral semaglutide treatment arms at week 26 (range: -0.40% to -1.59%). 
Placebo-adjusted reductions in body weight were dose-dependent and statistically significant for 
oral semaglutide treatment doses of 10 mg and above at week 26 (range: -3.61 kg to -6.98 kg). 
3.1.5.3
Safety
In the clinical trials completed so far, no unexpected safety findings have been identified for oral 
semaglutide administered up to 40 mg once daily. Consistent with other GLP-1 RAs, commonly 
reported AEs included nausea and vomiting, most of which were mild to moderate in severity. In 
line with findings for other GLP-1 RAs, an increase in heart rate and serum levels of lipase and 
amylase has also been observed in subjects exposed to oral semaglutide.
In addition to the 13 completed clinical trials with oral semaglutide, SNAC has been investigated in 
the programme of orally administrated heparin in combination with SNAC (heparin/SNAC). The 
heparin/SNAC programme (
) included 29 phase 1 trials (SNAC doses 
ranged from 0.172-10.5 g). In three of these trials, SNAC alone was investigated (to a maximum 
dose of 10.5 g). The trials covered formulation development, food effect, hepatic and renal 
impairment, age-effect and drug-drug interaction. The programme also included a total of three 
phase 2 and 3 trials in which the effects of orally delivered heparin solution (with >1.5 g SNAC 
three times a day) was investigated. The overall safety profile of oral semaglutide and 
heparin/SNAC indicates that SNAC is safe and well-tolerated.

3.1.6
Dulaglutide
Dulaglutide is a GLP-1 RA with prolonged action developed and marketed by Eli Lilly and 
Company under the trade name Trulicity®. Dulaglutide has been approved in Japan since 2015 for 
use as once-weekly s.c. injection for treatment of T2DM. Dulaglutide belongs to the same class of 
drugs as semaglutide and as such they share many of the same efficacy and safety characteristics. 
As dulaglutide is a marketed drug its characteristics are described in the EU summary of product 
characteristics (SmPC)26 and the local prescribing information27.
3.2
Rationale for the trial
Many patients with T2DM are not in glycaemic control with the currently marketed OADs. 
Nevertheless, treatment with more efficacious injectable therapies such as GLP-1 RAs and insulin 
are rarely added during the early stages of the disease. Oral semaglutide is the first GLP-1 RA in 
development in a tablet formulation and it has the potential of becoming a new attractive treatment 
option early in the treatment cascade due to its effects on both hyperglycaemia and body weight. 
The “Draft Guideline for Clinical Evaluation of Oral Hypoglycaemic Agents”28 (hearafter, draft AD 
guideline) provided by Ministry of Health, Labour and Welfare (MHLW), Japan, specifies that in 
order to obtain the indication “T2DM” long-term safety and efficacy of an investigational drug 
should be evaluated  in combination with any approved OAD that is supposed to be used in 
combination with the investigational drug in clinical practice in a sufficient number of Japanese 
patients. 
This trial will evaluate the long-term safety and efficacy of oral semaglutide in combination with 
each one of the already approved OADs (SU, glinide, TZD, α-GI and SGLT-2 inhibitor) in 
Japanese subjects with T2DM.

Trial design
5.1
Type of trial
This is a 52-week, randomised, open-label, active-controlled, parallel-group, multi-centre, single 
country trial with 4 treatment arms comparing the safety and efficacy of once-daily dosing of 3 dose 
levels of oral semaglutide (3, 7 and 14 mg) to once-weekly dosing of 0.75 mg dulaglutide 
subcutaneously in Japanese subjects with T2DM inadequately controlled on one OAD. The trial is 
with blinded dose allocation with regard to 3 dose levels of oral semaglutide.
Japanese subjects with T2DM inadequately controlled on one OAD will be randomised in a 2:2:2:1
manner to receive one of the following treatments as add-on to their background OAD medication: 
!
Oral semaglutide 3 mg once-daily
!
Oral semaglutide 7 mg once-daily
!
Oral semaglutide 14 mg once-daily
!
Dulaglutide 0.75 mg s.c. once-weekly
The background OAD medication must consist of one of the following: SU, glinide, TZD, α-GI or 
SGLT-2 inhibitor as monotherapy.
Randomisation will be stratified based on the type of background OAD medication 
(SU/glinide/TZD/α-GI/SGLT-2 inhibitor).
Total trial duration for the individual subject will be approximately 59 weeks. The trial includes a 2-
week screening period, followed by a 52-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.

5.2
Rationale for trial design
The trial was designed in accordance with the draft AD guideline28 and is in accordance with the 
advice of Pharmaceuticals and Medical Devices Agency (PMDA) obtained at the End of Phase 2 
meeting.
The number of subjects has been set based on the agreement with PMDA for the long-term safety 
evaluation as combination therapy with OADs based on the draft AD guideline.
The parallel treatment groups and a randomised design have been chosen to assess the safety and 
efficacy of once-daily dosing of oral semaglutide (3, 7 and 14 mg) compared to once-weekly dosing 
of 0.75 mg dulaglutide subcutaneously, both in combination with one OAD (either of SU, glinide, 
TZD, α-GI or SGLT-2 inhibitor). An open label design (between the oral semaglutide arms and the 
dulaglutide arm) has been chosen in accordance with the draft AD guideline as it clearly states the 
trial design of long-term combination trial (except for insulin combination) is open-labelled. 
Randomisation will be stratified based on the type of background OAD medication 
(SU/glinide/TZD/α-GI/SGLT-2 inhibitor) to ensure a 2:2:2:1 distribution of the 4 treatment arms 
(see Section 5.1) within each stratum.
There will be strict rescue criteria in place to ensure acceptable glycaemic control during the trial 
for all treatment arms.
The treatment duration of 52 weeks have been chosen according to the draft AD guideline and is 
considered adequate for the purpose of the trial. 
The follow-up period is 5 weeks to allow for wash-out of semaglutide.
5.3
Treatment of subjects
Treatment of subjects is summarised in Table 5–1.
Oral semaglutide treatment arms
Oral semaglutide is a long-acting GLP-1 RA to be administered orally once-daily. All subjects 
randomised to oral semaglutide will initiate treatment with 3 mg once-daily. Subjects randomised to 
a treatment dose of 7 and 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, followed by 4 weeks on 7 mg once daily (Table 5–1). All dose levels, including the dose-
escalation, will be blinded. To mitigate the risk of gastrointestinal AEs, it is important to follow the 
fixed 4-week dose escalation intervals. The dose must not be changed once the randomised dose of 
oral semaglutide has been reached.

Dulaglutide treatment arm
Dulaglutide is a GLP-1 RA to be administered subcutaneously once-weekly. Treatment with 
dulaglutide injections will be initiated at 0.75 mg once-weekly without dose escalation. The dose 
must not be changed during the course of the trial.

Dosing instructions
Oral semaglutide dosing
Absorption of oral semaglutide is significantly affected by food and fluid in the stomach, hence 
dosing should be once-daily in the morning in a fasting state and at least 30 minutes before the first 
meal of the day. The tablet can be taken with up to half a glass of water (approximately 120 mL). 
The tablet must be swallowed whole by the subject and must not be broken or chewed (see Table 9–
2). Furthermore, other oral medication can be taken 30 minutes after administration of the oral trial 
product.
Dulaglutide dosing
The administration of dulaglutide should be in accordance with the current approved label26,27.
Dulaglutide should be administered once-weekly, on the same day of the week and it can be given 
at any time of day independent of meals. Dulaglutide is injected subcutaneously in the abdomen, 
thigh or upper arm. When administered in the same region, the injection site should be changed by 
every injection.

5.3.2
Background medication
After signing the informed consent, subjects must continue their background OAD medication 
(either of SU, glinide, TZD, α-GI or SGLT-2 inhibitor) throughout the entire trial. The background 
OAD 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 a safety concern 
related to the background medication arises, e.g. if the subject has unacceptable hypoglycaemia on a 
background of SU in which case the dose of SU can be reduced. The type of the background OAD 
medication must not be changed during the trial.
In addition, all background medication:
!
is considered to be non-investigational medicinal product (NIMP)
!
will not be provided by Novo Nordisk. 
!
should be used in accordance with standard of care and current approved label in Japan
!
should not exceed the maximum approved dose in Japan
5.4
Treatment after discontinuation of trial product
When discontinuing trial products, either at the scheduled end of treatment visit (see Section 8.1.5) 
or if trial product is discontinued prematurely (see Section 8.1.6), the subject should be switched to 
a suitable marketed product at the discretion of the investigator while taking into consideration the 
long half-life of semaglutide. Throughout the protocol, last date on trial product is defined as date of 
the subject’s last dosage of trial product.
As this trial is a phase 3a trial, oral semaglutide will not be available for prescription until after 
marketing authorisation.
5.5
Rationale for treatment  
For phase 3 development of oral semaglutide, the three dose levels (3, 7 and 14 mg), treatment 
initiation with the lowest dose and the 4-week dose escalation steps have been chosen based on data 
from the global phase 2 dose-finding trial (NN9924-3790). This regimen is expected to have the 
optimal benefit-risk profile for further development for treatment of T2DM in the PIONEER 
programme. 
Dulaglutide has been chosen as active comparator since it is an important comparator within the 
same drug-class as semaglutide. Treatment with dulaglutide injection will be in accordance with the 
current approved label26,27.
The duration of randomised treatments is considered adequate to collect sufficient data on safety 
and efficacy in accordance with the trial objectives.

6.4
Rescue criteria
Subjects with persistent and unacceptable hyperglycaemia should be offered treatment 
intensification. To allow time for dose escalation to maximum dose 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. If the confirmatory FPG also 
exceeds the value described below, the subject should be offered rescue medication. In this trial, 
rescue medication means intensification of existing background OAD medication and/or initiation 
of new anti-diabetic medication:
!
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 treatment
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 treatment

It is important for trial integrity that only subjects actually needing treatment intensification (as 
defined above) are started on rescue medication. Subjects that are started on rescue medication 
should continue to follow the protocol-specified visit schedule. Rescue medication should be 
prescribed at investigator’s discretion as add-on to randomised treatment and according to clinical 
practice in Japan or ADA/European Association for the Study of Diabetes guidelines29,30 (excluding 
GLP-1 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 NIMP and will not be provided by Novo Nordisk A/S. 
6.5
Criteria for premature discontinuation of trial product
All efforts should be made to keep the subject on trial product. However, the subject may be 
prematurely discontinued from trial product at the discretion of the investigator due to a safety 
concern. For additional guidance, refer to appendix B.
The subject must be prematurely discontinued from trial product, if the following applies: 
1. Safety concern related to trial product or unacceptable intolerability
2. Included in the trial in violation of the inclusion and/or exclusion criteria
3. Pregnancy
4. Intention of becoming pregnant
5. Simultaneous participation in another clinical trial of an approved or non-approved IMP
6. Calcitonin ≥ 100 ng/L
If a criterion for premature discontinuation of trial product is met, trial product should not be re-
initiated but subjects should continue with the scheduled site contacts.
See Section 8.1.6 for procedures to be performed for subjects discontinuing trial product 
prematurely.
6.6
Withdrawal from trial
The subject may withdraw consent at will at any time. The subject’s request to withdraw from the 
trial must always be respected. Only subjects who withdraw consent should be considered as 
withdrawn from trial.
See Section 8.1.7 for procedures to be performed for subjects withdrawing consent.

Rationale for trial population 
The trial population will include Japanese subjects with T2DM treated with stable doses of SU, 
glinide, TZD, α-GI or SGLT-2 inhibitor as monotherapy for at least 60 days prior to screening as 
changes in background OAD medication shortly before trial participation may potentially impact 
data interpretation. The HbA1c limits 7.0%–10.5% (53–91 mmol/mol) have been chosen to include 
subjects needing intensification of anti-diabetic medication. The upper limit will secure that 
subjects with severely dysregulated T2DM are not enrolled in the trial. In addition, FPG and HbA1c
will be monitored throughout the trial and rescue medication may be initiated in subjects with 
persistent, unacceptable hyperglycaemia. No BMI or blood pressure restrictions will be applied. 
Subjects with liver test abnormalities (ALT>2.5 x UNL) will be excluded to avoid potential 
confounding of liver safety assessments. In addition, subjects with severe or end-stage renal 
impairment will be excluded due to restrictions in the SmPC of dulaglutide26 which is comparator in 
this trial, and the label of SGLT-2 inhibitors that are one of the allowed background OAD 
medications. As SGLT-2 inhibitors have been associated with euglycaemic diabetic ketoacidosis, 
subjects with a history of diabetic ketoacidosis will also be excluded from this trial. Overall, the 
eligibility criteria allow for enrolment of a relatively broad trial population resembling the target 
population in common practice. Finally, the trial population was selected on the basis of the “draft
AD guideline”28 and the advice from the PMDA.

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. All subjects screened during the recruitment period and found eligible for randomisation 
can be randomised within the timelines specified in the flow chart (see Section 2).
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 Disclosure31, it will also be disclosed according to other applicable 
requirements such as those of the International Committee of Medical Journal Editors (ICMJE)32, 
the U.S. Food and Drug Administration Amendment Act (FDAAA)33, European Commission 
Requirements34,35 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
The following sections describe the assessments and procedures. These are also included in the flow 
chart (see Section 2). 
Informed consent must be obtained before any trial related activity, see Section 18.2.
Refer to flowchart (Section 2) for number and timing of visits and specific assessments to be 
performed. 
Each subject will attend 12 site visits and 2 phone contacts. It is the responsibility of the 
investigator to ensure that all site visits and phone contacts occur according to the flow chart.
Planned visits can be conducted and re-scheduled within the allowed visit window. If a visit is 
missed and it is not possible to re-schedule, every effort should be made to ensure information is 
collected at a telephone contact (within the visit window) and entered into the eCRF. Subjects will 
be invited for the next scheduled visit according to the visit schedule.
The investigator must keep a subject screening log, a subject identification code list and a subject 
enrolment log. Only subjects who have signed the informed consent form should be included on the 
logs. The subject screening log and subject enrolment log may be combined in one log. 
The investigator must keep a log of staff and a delegation of task(s) list at site. Investigator must 
sign the log of staff and the delegation of task(s) at site prior to the delegation of tasks.
8.1.1
Screening (visit 1)
At screening, subjects will be provided with a card stating that they are participating in a trial and 
giving contact address(es) and telephone number(s) of relevant trial site staff. Subjects should be 
instructed to return the card to the investigator at the last trial visit or to destroy the card after the 
last visit.
A screening session must be made in the IWRS. Each subject will be assigned a unique 6-digit 
subject number which will remain the same throughout the trial.
Once all data relating to visit 1 have been obtained, these must be reviewed, dated and signed by the
investigator and/or documented in medical records to assess that the subject is eligible to continue 
in the trial.

Screening failures: 
For screening failures the screening failure form in the eCRF must be completed with the reason for 
not continuing in the trial. Serious adverse events (SAEs) from screening failures must be 
transcribed by the investigator into the eCRF. Follow-up on SAEs must be carried out according to 
Section 12.
A screening failure session must be made in the IWRS. The case book must be signed.
Re-screening is NOT allowed if the subject has failed one of the inclusion or exclusion criteria; this 
includes re-sampling if the subject has failed one of the inclusion or exclusion criteria related to 
laboratory parameters. However, in case laboratory samples are lost (e.g. haemolysed/displaced), 
re-sampling is allowed. 
8.1.2
Fasting visits
The subjects must attend several visits in a fasting state (see Section 2). 
Fasting for blood sampling is defined as no food or liquid within the last 8 hours prior to blood 
sampling, however water is allowed up until 2 hours prior to blood sampling.
For the subjects allocated to oral semaglutide, trial product must be taken after blood sampling (see 
Section 5.3.1 for dosing instructions). Other oral medication can be taken 30 minutes after trial 
product. Injectable medications can be administered after blood sampling.
For the subjects allocated to dulaglutide, if the day of fasting visit falls on the day of his/her 
dulaglutide dosing, the trial product and/or other oral and injectable medications must be taken after 
the blood sampling has been performed.
In case a subject attends a fasting visit in a non-fasting state, all non-fasting measurements should 
be performed. The subject should return to the site in a fasting state to have the fasting blood 
samples done within the visit window for the relevant visit.
For fasting samples, see Section 8.3.1.
8.1.3
Randomisation and trial product administration (visit 2)
Eligible subjects will be randomised into one of 4 treatment arms. The randomisation session must 
be performed in the IWRS which will allocate the dispensing unit number (DUN) of trial product to 
be dispensed to the subject.
All visit 2 assessments must be performed before administration of first dose of trial product.
Trial products (see Section 9) will be dispensed to the subject by the site, hospital pharmacy or 
equivalent at each site visit during the trial from randomisation to last visit before the End-of-

Phone contacts
The planned phone contacts 3 and 5 should be conducted 2 and 6 weeks (±3 days) after 
randomisation respectively (see Section 2). 
8.1.5
End-of-treatment (visit 13) and Follow-up (visit 14)
Subjects, who stay on trial product throughout the trial, must attend the End-of-treatment visit 
(visit 13) 52 weeks after randomisation (±3 days visit window) and the Follow-up visit (visit 14) 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 13 (see Section 10).
In case the subject cannot be reached (by clinic visit or phone contact) at the scheduled visit 14, the 
site should consult the contacts provided by the subject (e.g. close relatives), relevant physicians
and medical records to collect health status. If no health status can be collected, the subject should 
be considered lost to follow up and this should be specified in the end-of-trial form. 
8.1.6
Premature discontinuation of trial product and follow-up (visits 13A and 14A)
Subjects, who discontinue trial product prematurely, should attend visit 13A scheduled to take place 
on the day of discontinuation of trial product (+3 days visit window). Visit 14A should be 
scheduled 5 weeks (+3 days visit window) after the last date on trial product. The primary reason 
for premature discontinuation of trial product must be specified in the end-of-trial form in the eCRF, 
and final drug accountability must be performed. A treatment discontinuation session must be made 
in the IWRS at visit 13A (see Section 10).
If premature discontinuation of trial product is decided during a scheduled visit, the visit will be 
converted into a visit 13A and trial procedures must be performed accordingly.
Subjects should continue with the originally scheduled site contacts after visit 14A and up to and 
including visit 13. If necessary, in order to retain the subject in the trial, site visits can be replaced 
by phone contacts after visit 14A. However, if a subject is unable or unwilling to attend all 
subsequent visit(s), the investigator should at least aim to have the subject attend the scheduled visit 
9 (week 26) and visit 13 (week 52) as these visits should be performed for all subjects, if at all 
possible (except subjects who withdraw informed consent, see Section 8.1.7). 
Subjects, who only agree to attend or provide health status at the planned visit 13, should not be 
considered withdrawn from the trial. In case the subject cannot be reached (by clinic visit or phone 
contact) at the scheduled visit 13, the site should consult the contacts provided by the subject (e.g.

be collected, the subject should be considered lost to follow-up and this should be specified in the 
end-of-trial form. 
In summary, subjects should stay in the trial irrespective of lack of adherence to randomised 
treatment, lack of adherence to visit schedule, missing assessments or trial product discontinuation 
for any reason. Only subjects who decline any further contact with the site in relation to the trial 
should be considered as withdrawn from the trial (for withdrawal procedures, see Section 8.1.7). 
8.1.7
Withdrawals
If a subject considers withdrawing from the trial, the investigator must aim to undertake procedures 
for visit 13A as soon as possible and visit 14A should be scheduled 5 weeks (+3 days visit window) 
after the last date on trial product, if the subject agrees to it.
The end-of-trial form must be completed and final drug accountability must be performed even if 
the subject is not able to come to the trial site. A treatment discontinuation session must be made in 
the IWRS (see Section 10). The case book must be signed. 
Although a subject is not obliged to give his/her reason(s) for withdrawing consent, the investigator 
must make a reasonable effort to ascertain the reason(s), while fully respecting the subject’s rights. 
Where the reasons are obtained, the primary reason for withdrawing consent must be specified in 
the end-of-trial form in the eCRF.
8.1.8
Investigator assessments
Review of diaries, PROs, laboratory reports, ECGs and fundus photography/dilated fundoscopy 
must be documented either on the documents or in the subject’s medical record.
If clarification of entries or discrepancies in the diary or PROs is needed, the subject must be 
questioned and a conclusion made in the subject’s medical record. Care must be taken not to bias 
the subject.
The documents must be retained at the site as source documentation.
For ECGs, physical examinations and eye examinations, the evaluations must follow the categories:
!
Normal

A central FPG result ≤3.9 mmol/L (70 mg/dL) in relation to planned fasting visits should not be 
reported as a hypoglycaemic episode but as a clinical laboratory adverse event (CLAE) at the 
discretion of the investigator (see Section 12.1.1).
8.3.2
Self-measured plasma glucose (SMPG)
At visit 1, subjects will be provided with a blood glucose meter (BG meter) including auxiliaries as 
well as instructions for use. The subjects will be instructed in how to use the device, and the 
instruction will be repeated as necessary during the trial. In case a hypoglycaemic episode is 
suspected, the provided BG meter should be used for SMPG measurement.
The BG meters use test strips calibrated to plasma values. Therefore, all measurements performed 
with capillary blood are automatically calibrated to plasma equivalent glucose values, which will be 
shown on the display. 
Only the BG meters provided by Novo Nordisk or the same model purchased by the trial site should 
be used for the measurements required in the protocol.
Subjects should be instructed in how to record the results of the SMPG values in the diaries. The 
record of each SMPG value should include date, time and value. All data from the diary must be 
transcribed into the eCRF during or following the contact. If obtained via phone and a discrepancy 
is later detected between the diary and the SMPG data obtained at the phone contact, the values in 
the eCRF must be corrected.
Occasional review by the investigator of the values stored in the memory of the BG meter and 
correct reporting of these in the diary is advised in order to ensure adequacy of the data reported in 
the trial database. 
7-point self-measured plasma glucose profile
The subject will be instructed to perform a 7-point SMPG profile 3 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
SMPG profile should preferably be taken within a week prior to the visit.
The record of each SMPG measurement should include the following seven time points:
!
before breakfast
!
90 minutes after start of breakfast
!
before lunch
!
90 minutes after start of lunch
!
before dinner

Body weight and height
Body weight must be measured and recorded in the eCRF in kilogram (kg), 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 and recorded in the eCRF to nearest ½ cm.
8.3.4
Waist circumference
The waist circumference is defined as the minimal abdominal circumference located midway 
between the lower rib margin and the iliac crest.
The measurement of waist circumference must be performed and recorded in the eCRF. Waist 
circumference is measured in the horizontal plane and rounded up or down to the nearest ½ cm 
using a non-stretchable measuring tape. The same measuring tape should be used throughout the 
trial.
The circumference should be measured when the subject is in a standing position, with an empty 
bladder and wearing light clothing. The subject should be standing, feet together with arms down 
their side and waist accessible. The tape should touch the skin but not compress soft tissue and 
twists in the tape should be avoided. The subject should be asked to breathe normally and the 
measurement should be taken when the subject is breathing out gently.

Diabetes Therapy-Related QOL (DTR-QOL) questionnaire39
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 15 minutes to 
complete the two questionnaires. Subjects should be given the opportunity to complete the 
questionnaires by themselves without interruption. The completed questionnaires must be reviewed 
for potential adverse events and missing data while the subject is still at the site. All results from the 
questionnaires must be transferred into the eCRF.
SF-36 acute version
SF-36v2™ is a commonly used instrument to evaluate PROs, also in the T2DM area. 
SF-36v2™ acute version measures the individual overall health related quality of life on 8 domains; 
Physical functioning, Role physical, Bodily pain, General health, Vitality, Social functioning, Role 
emotional and Mental health. The acute version’s questions are based on a recall period of one

methods, see Section 8.2.5.
In case a menstrual period is missed or if pregnancy is suspected between the scheduled visits, a 
urine pregnancy test should be performed. Investigator should instruct the subject to contact the site 
in case the pregnancy test is positive. At visit 2, females of childbearing potential will be provided 
with urine dip-sticks for pregnancy test at home.
8.4.8
Hypoglycaemic episodes
Plasma glucose (PG) should always be measured and recorded when a hypoglycaemic episode is 
suspected.
All PG values:
!
≤ 3.9 mmol/L (70 mg/dL) or
!
> 3.9 mmol/L (70 mg/dL) occurring in conjunction with hypoglycaemic symptoms
should be reported in the diary according to the instructions below throughout the trial from visit 1 
to end of trial.
Upon onset of a hypoglycaemic episode the subject is recommended to measure PG every 15 
minutes until the SMPG value is > 3.9 mmol/L (70 mg/dL) and/or symptoms have been resolved in 
accordance to current guidelines41.
A SMPG value ≤ 3.9 mmol/L (70 mg/dL) or hypoglycaemic symptoms must trigger a 
hypoglycaemic episode form to be completed by the subject. Repeated SMPG measurements and/or 
symptoms will per default be considered as one hypoglycaemic episode until a succeeding SMPG 
value is > 3.9 mmol/L (70 mg/dL) and/or symptoms have been resolved. One hypoglycaemic 
episode form is to cover these measurements and/or symptoms. 
In case of several low SMPG values within the hypoglycaemic episode, the lowest value is the one 
that will be reported as the SMPG value for the hypoglycaemic episode but the start time of the 
episode will remain as the time for the first SMPG value and/or symptom.
The record should include the following information: 
!
Start date and time of the hypoglycaemic episode.
!
Stop date and time of the hypoglycaemic episode (stop time is the first time the PG value is >
3.9 mmol/L (70 mg/dL) and/or symptoms have been resolved).
If a stop date and time is not reported, a hypoglycaemic episode will cover a period of 60
minutes.

If the severity of a hypoglycaemic episode aggravates, only one hypoglycaemic episode should
be reported reflecting the most severe degree of hypoglycaemia.
!
Date and time of last trial product administration and date, time and dose of selected anti-
diabetic medications prior to the episode.
!
Date and time of last main meal (not including snacks) prior to the episode.
!
Whether the episode occurred in relation to physical activity.
!
Change in any concomitant illness.
!
Any sign of fever and/or other acute disease.
!
Whether the subject was asleep when the episode occurred.
–
If yes, whether the symptoms of the episode woke up the subject.
The answer to the question: "Was the subject able to treat him/herself?" must be answered "No" for 
an episode requiring assistance of another person to actively administer carbohydrate, glucagon, or 
take other corrective actions. PG concentrations may not be available during an event, but 
neurological recovery following the return of PG to normal is considered sufficient evidence that 
the event was induced by a low PG concentration42.
Oral carbohydrates must not be given if the subject is unconscious.
If the question "Was the subject able to treat him/herself?" is answered "No", the following 
information should be recorded by the subject:
!
Who assisted in the treatment of the hypoglycaemic episode (i.e. medical person or non-medical
person)?
!
Where the treatment was administered (in clinic/emergency room/hospital or other. If the
subject was treated in clinic/emergency room/hospital, whether they were transported in an
ambulance or not)
!
Type of treatment provided by another person (i.e. oral carbohydrates, glucagon, IV glucose or
other)
!
Were symptoms alleviated after administration of treatment?
!
Factors contributing to the episode (i.e. physical activity, missed meal, diet change, medication
error [i.e. overdose, mix-up between products, incorrect use of device], other factors not listed
or unknown)
!
Did the subject experience seizure?

–
General malaise: headache or malaise (feeling discomfort/unease)
!
Other symptoms
The Investigator must review the diary for low SMPG values not reported as hypoglycaemic 
episodes (see Section 2 for relevant visits). The subject must be questioned whether any of the low 
values were severe i.e. whether the subject was able to self-treat or not. If the subject was not able 
to self-treat it has to be reported as a severe hypoglycaemic episode on a hypoglycaemic episode 
form.
Low SMPG values for non-severe hypoglycaemic episodes not having a hypoglycaemic episode 
form completed within 7 days since the SMPG measurement should be reported on a 
hypoglycaemic episode form with as much information as possible. Novo Nordisk will not query 
for additional data except for the start date, SMPG value and whether the subject was able to self-
treat due to decreased validity of such data43,44.
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.
8.5
Laboratory assessments
The laboratory analyses will mainly be performed by a central laboratory. IgE anti-semaglutide 
antibodies and anti-semaglutide binding antibodies(see appendix B) will be analysed by Novo 
Nordisk A/S. For some of the analyses related to suspicion of acute pancreatitis and 
hypersensitivity, a local laboratory must be used (see appendix B).
The handling, transportation and storage of biological samples are described in the laboratory 
manual (for central and special laboratory details see Attachment I).
Samples will be coded in order to keep subject identity anonymous.
Laboratory samples not drawn on the day of the actual visit should preferably be drawn on another 
day within the visit window stated in the flow chart (see Section 2). Please note that a laboratory 
sample pertaining to a specific visit must always be reported to that visit.

For some of the samples drawn during the trial, subjects will be asked to attend the site visits fasting 
(fasting for blood sampling is defined in Section 8.1.2).
The central laboratory will provide laboratory results to the investigator on an ongoing basis. 
The laboratory provides results to the trial sites in the units preferred by the trial sites while the 
results that are transferred to the trial database will always be in SI units.
The laboratory equipment may provide analyses not requested in the protocol but produced 
automatically in connection with the requested analyses according to specifications in the laboratory 
standard operating procedures. Such data will not be transferred to the trial database, but abnormal 
values will be reported to the investigator. The investigator must review all laboratory results for 
concomitant illnesses and AEs and report these according to Section 8.2.3 and Section 12.
Laboratory samples will be destroyed at the latest at the completion of the CTR, except samples 
obtained for hypersensitivity. Hypersensitivity samples will be stored as described in Section 24.2.

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

11 Randomisation procedure and breaking of blinded codes
The trial is an open label trial (between oral semaglutide arms and a dulaglutide arm), but partly 
double-blinded with regard to three dose levels of oral semaglutide (3, 7 and 14 mg). A 
randomisation session will be carried out for all subjects using the 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.
Randomisation will be stratified by background OAD medication with the following levels:
!
SU
!
glinide
!
TZD
!
α-GI
!
SGLT-2 inhibitor
to ensure a 2:2:2:1 distribution of the four treatment arms (see Section 5.1) within strata.
The aim is to randomise a minimum of 455 Japanese subjects, i.e. 147 subjects in the strata of SU 
monotherapy and 77 subjects in the strata of each of the remaining OAD monotherapy (glinide, 
TZD, α-GI and SGLT-2 inhibitor). 
11.1
Breaking of blinded codes
Since the trial is partly double-blinded with regard to three dose levels of semaglutide, the blinded 
codes may possibly be broken for the subjects allocated to oral semaglutide arms. The IWRS will 
notify Novo Nordisk (monitor and the Global Safety department) immediately after the code is 
broken.
The code for a particular subject allocated to oral semaglutide arm may be broken in a medical 
emergency if knowing the actual dose level 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 dose level allocation will be accessible to the investigator and the 
Novo Nordisk Global Safety department. If the IWRS is not accessible at the time of code break the 
IWRS helpdesk should be contacted. Contact details are listed in Attachment I. If the code has been 
broken, the subject must discontinue treatment with trial product but be asked to continue in the 
trial (see Section 8.1.6). A treatment discontinuation session must be completed in the IWRS.

12 Adverse events, and technical complaints and pregnancies
12.1
Definitions
12.1.1
Adverse event 
An adverse event (AE) is any untoward medical occurrence in a subject administered a medicinal 
product, and which does not necessarily have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory 
finding), symptom or disease temporally associated with the use of a product, whether or not 
considered related to the product. 
An AE includes:
!
A clinically significant worsening of a concomitant illness.
!
A clinical laboratory adverse event (CLAE): a clinical laboratory abnormality which is
clinically significant, i.e. an abnormality that suggests a disease and/or organ toxicity and is of a
severity that requires active management. Active management includes active treatment or
further investigations, for example change of medicine dose or more frequent follow-up due to
the abnormality.
The following should not be reported as AEs:
!
Pre-existing conditions, including those found as a result of screening or other trial procedures
performed before exposure to trial product (pre-existing conditions should be reported as
medical history or concomitant illness).
!
Pre-planned procedures unless the condition for which the procedure was planned has worsened
from the first trial related activity after the subject has signed the informed consent.
!
Non-serious hypoglycaemia is an AE, but is reported on a hypoglycaemic episode form instead
of on an AE form, see Section 8.4.8.
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.
12.1.2
Serious adverse event
A serious adverse event (SAE) is an experience that at any dose results in any of the following:
!
Death.
!
A life-threateninga experience.
!
In-patient hospitalisationb or prolongation of existing hospitalisation.
!
A persistent or significant disability or incapacityc.
!
A congenital anomaly or birth defect.
!
Important medical events that may not result in death, be life threateninga or require
hospitalisationb may be considered an SAE when - based on appropriate medical judgement -
they may jeopardise the subject and may require medical or surgical intervention to prevent one
of the outcomes listed in the definition of SAEd.
a.
The term “life threatening” in the definition of SAE refers to an event in which the subject
was at risk of death at the time of the event. It does not refer to an event which hypothetically
might have caused death if it was more severe.
b.
The term “hospitalisation” is used when a subject:
o
Is admitted to a hospital or in-patient, irrespective of the duration of physical stay, or
o
Stays at the hospital for treatment or observation for more than 24 hours
Medical judgement must always be exercised, and when in doubt, the hospital contact should 
be regarded as a hospitalisation. Hospitalisations for administrative, trial related and social

purposes do not constitute AEs and should therefore not be reported as AEs or SAEs. Hospital 
admissions for surgical procedures, planned before trial inclusion, are not considered AEs or 
SAEs.
c.
A substantial disruption of a subject’s ability to conduct normal life functions (e.g. following
the event or clinical investigation the subject has significant, persistent or permanent change,
impairment, damage or disruption in his/her body function or structure, physical activity
and/or quality of life).
d.
For example intensive treatment in an emergency room or at home of allergic bronchospasm,
blood dyscrasia or convulsions that do not result in hospitalisation, or development of drug
dependency or drug abuse.
The following adverse events must always be reported as an SAE using the important medical event 
criterion if no other seriousness criteria are applicable:
!
suspicion of transmission of infectious agents via the trial product
!
risk of liver injury defined as ALT or AST >3 x UNL and total bilirubin >2 x UNL, where no
alternative aetiology exists (Hy's law).
Additional assessments should be made for events meeting the criterion of Hy’s law as stated above 
(see appendix B).
12.1.3
Non-serious adverse event
A non-serious AE is any AE which does not fulfil the definition of an SAE.
12.1.4
Medication errors
A medication error concerning trial products is defined as:
!
Administration of wrong drug or use of wrong device.
Note: Use of wrong DUN is not considered a medication error unless it results in administration
of wrong drug.
!
Wrong route of administration, such as intramuscular instead of s.c.
!
Administration of an overdose with the intention to cause harm (e.g. suicide attempt), misuse or
abuse of trial product.
!
Accidental administration of a higher dose than intended. A higher dose of semaglutide is a dose
of at least one tablet more than the intended dose, and for dulaglutide a higher dose than
0.75 mg/day; however, the administered dose must deviate from the intended dose to an extent
where clinical consequences for the trial subject were likely to happen as judged by the
investigator, although they did not necessarily occur.
Medication errors must be reported on an AE form and a specific event form, see Section 8.4.1.1, 
12.1.5 and appendix B.

12.1.6
Technical complaints
A technical complaint is any written, electronic, or oral communication that alleges product 
(medicine or device) defects. The technical complaint may be associated with an AE, but does not 
concern the AE itself.
Examples of technical complaints:
!
The physical or chemical appearance of trial products (e.g. discoloration, particles or 
contamination)
!
All packaging material including labelling
!
Problems related to devices (e.g. to the injection mechanism, dose setting mechanism or push 
button)
12.2
Reporting of adverse events
All events meeting the definition of an AE must be collected and reported. This includes events 
occurring from the first trial-related activity after the subject has signed the informed consent until 
the end of the post-treatment follow-up period (visit 14) for subjects on trial product OR until the 
end of trial (visit 13 or 14A, whichever comes last) for the subjects who have discontinued trial 
product prematurely. Events for withdrawn subjects will be collected and reported until last trial 
related contact with the subject. The events must be recorded in the applicable eCRF forms in a 
timely manner, see timelines below and Figure 12–1.
During each contact with the trial site staff, the subject must be asked about AEs and technical 
complaints, for example by asking: "Have you experienced any problems since the last contact?"
All AEs, either observed by the investigator or subject, must be reported by the investigator and 
evaluated.
All AEs must be recorded by the investigator in the eCRF 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 in the eCRF.
For SAEs, a safety information form (SIF) must be completed in addition to the AE form. A SIF is 
a form to collect supplementary clinical information. If several symptoms or diagnoses occur as part 
of the same clinical picture, one SIF can be used to describe all the SAEs.
AEs requiring additional data collection must be reported using both the AE form and the specific 
event form. A specific event form is a form tailored to collect specific information related to the 
individual event. See appendix B for details about the events and the additional information to 
report. In case any of these events fulfil the criteria for seriousness in Section 12.1.2, then the event 
should be reported as serious.

Some events will undergo event adjudication by the EAC, please refer to Section 12.7.2. For AEs 
qualifying for event adjudication, the adjudication form will also have to be completed in the eCRF. 
The adjudication form is a checklist of clinical data to be provided from the site.
For an overview of AEs requiring additional data collection and AEs that will undergo event 
adjudication, please see Table 12–1.
For all non-serious AEs, the applicable forms should be signed when the event is resolved or at the 
end of the trial at the latest.
Timelines for initial reporting of AEs:
The investigator must complete the following forms in the eCRF within the specified timelines:
!
SAEs: The AE form within 24 hours and the SIF within 5 calendar days of the investigator's 
first knowledge of the SAE.
Both forms must be signed within 7 calendar days from the date the information was entered in 
the eCRF.
For SAEs requiring reporting on a specific event form: In addition to the above, the specific 
event form within 14 calendar days from the investigator’s first knowledge of the AE.
!
Events for adjudication: The adjudication form should be completed within 14 calendar days 
of the investigator’s first knowledge of the AE, see Section 12.7.2. The investigator should 
preferably provide the medical documentation within 4 weeks of event identification according 
to instructions in the event adjudication site manual. 
If the eCRF is unavailable, the concerned AE information must be reported on a paper AE form and 
sent to Novo Nordisk by fax, e-mail or courier within the same timelines as stated above. When the 
eCRF becomes available again, the investigator must enter the information on the form into the 
eCRF.
Contact details (fax, telephone, e-mail and address) are provided in the investigator trial master file.

Reporting of AEs 
Novo Nordisk assessment of AE expectedness: 
Novo Nordisk assessment of expectedness is performed according to the following reference 
documents: 
!
IB for oral Semaglutide (NN9924)25; current version and any updates thereto.
!
Summary of Product Characteristics (SmPC) for Trulicity® (dulaglutide)26; current version and
any updates thereto.
Reporting of trial product-related SUSARs by Novo Nordisk:
Novo Nordisk will notify the investigator of trial product-related suspected unexpected serious 
adverse reactions (SUSARs) in accordance with local requirements and ICH GCP1. In addition, the 
investigator will be informed of any trial-related SAEs that may warrant a change in any trial 
procedure.
In accordance with regulatory requirements, Novo Nordisk will inform the regulatory authorities, 
including European Medicines Agency (EMA), of trial product-related SUSARs. In addition, Novo 
Nordisk will inform the institutional review boards (IRBs) of trial product-related SUSARs in 
accordance with local requirement and ICH GCP1, unless locally this is an obligation of the 
investigator.

Novo Nordisk products used as concomitant medication or non-investigational medicinal 
product:
If an AE is considered to have a causal relationship with a Novo Nordisk marketed product used as 
non-investigational medicinal product or concomitant medication in the trial, it is important that the 
suspected relationship is reported to Novo Nordisk, e.g. in the alternative aetiology section on the 
SIF. Novo Nordisk may need to report this AE to relevant regulatory authorities.
12.3
Follow-up of adverse events
The investigator must record follow-up information by updating the medical records and the forms 
in the eCRF.
Follow-up information must be reported to Novo Nordisk according to the following:
!
SAEs: All SAEs must be followed until the outcome of the event is “recovered/resolved”,
“recovered/resolved with sequelae” or “fatal”, and until all queries have been resolved. Cases of
chronic conditions, cancer or AEs 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.
!
Events for adjudication: If new information becomes available for events in scope of
adjudication, this must be uploaded to the adjudication database in order for the EAC to
evaluate if re-adjudication is needed.
The investigator must ensure that the recording of the worst case severity and seriousness of an 
event is kept throughout the trial. A worsening of an unresolved AE must be reported as follow up 
with re-assessment of severity and/or seriousness of the event.

Dulaglutide 0.75 mg/0.5 mL, pre-filled pen
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 the Customer Complaint Center, Novo Nordisk.
Contact details (fax, e-mail and address) are provided in Attachment I to the protocol.
The investigator must assess whether the technical complaint is related to any AEs or SAEs.
Technical complaints must be reported on a separate technical complaint form: 
!
One technical complaint form must be completed for each affected DUN
!
If DUN is not available, a technical complaint form for each batch, code or lot number must be
completed.
The investigator must complete the technical complaint form in the eCRF within the following 
timelines of the trial site obtaining knowledge of the technical complaint:
!
Technical complaint assessed as related to an SAE within 24 hours
!
All other technical complaints within 5 calendar days
If the eCRF is unavailable or when reporting a technical complaint that is not subject related, the 
information must be provided on a paper form by fax, e-mail or courier to the 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

sample and the corresponding technical complaint form must be clearly separated.
The investigator must ensure that the technical complaint sample contains the code or lot number 
and, if available, the DUN. All parts of the DUN should be returned.
If the technical complaint sample is unobtainable, the investigator must specify on the technical 
complaint form why it is unobtainable. 
Storage of the technical complaint sample must be done in accordance with the conditions 
prescribed for the product.
12.5
Pregnancies
12.5.1
Pregnancies in female subjects 
Female subjects must be instructed to notify the investigator immediately if they become pregnant 
during the trial. The investigator must report any pregnancy in subjects who have received trial 
product(s).
The investigator must follow the pregnancy until the pregnancy outcome and the newborn infant is 
one month of age.
The investigator must report information about the pregnancy, pregnancy outcome and health of the 
newborn infant(s), as well as AEs in connection with the pregnancy and AEs in the foetus and 
newborn infant.
The following must be collected and reported by the investigator to Novo Nordisk - electronically 
(e.g. in PDF format), or by fax or courier:
1. Reporting of pregnancy information
Information about the pregnancy and pregnancy outcome/health of the newborn infant(s) has to 
be reported on Maternal Form 1A and 1B, respectively.
When the pregnancy outcome is abnormal (i.e. congenital anomalies, foetal death including 
spontaneous abortion and/or any anomalies of the foetus observed at gross examination or 
during autopsy), and/or when a congenital anomaly is diagnosed within the first month, further 
information has to be reported for the female subject on Maternal Form 2. In addition, 
information from the male partner has to be reported on the Paternal Form, after an informed 
consent has been obtained from the male partner. 
Initial reporting and follow-up information must be reported within 14 calendar days of the 
investigator's first knowledge of initial or follow-up information.

2. Reporting of AE information
The investigator has to report AEs in connection with the pregnancy as well as in the foetus and 
newborn infant(s). The SAEs that must be reported include abnormal outcome, such as foetal 
death (including spontaneous abortion), congenital anomalies (including those observed at gross 
examination or during autopsy of the foetus), as well as other pregnancy complications fulfilling 
the criteria of an SAE.
Forms and timelines for reporting AEs:
Non-serious AEs:

It must be clearly stated in the AE diagnosis field on the AE form if the event occurred in 
the subject, foetus or newborn infant. If the AE occurred in the foetus or newborn infant, 
the AE can only be reported on paper AE and safety information form.
Any queries or follow-up requests from Novo Nordisk to non-serious AEs, SAEs and pregnancy 
forms must be responded to by the investigator within 14 calendar days from the date of receipt of 
the request, unless otherwise specified in the follow-up request.
12.6
Precautions and/or overdose – Oral semaglutide
There are no specific antidotes to semaglutide. Treatment of an overdose should be symptomatic.
There is a potential risk of hypoglycaemia during dosing with semaglutide. The typical signs and 
symptoms of a non-severe hypoglycaemia include: hunger, slight headache, nausea, light-
headedness, palpitations and sweating. Symptoms of non-severe hypoglycaemia should be treated 
by ingestion of carbohydrates. 
Severe hypoglycaemia resulting in loss of consciousness should be treated according to best 
available medical practise. 
One case of accidental overdose of oral semaglutide was reported in the NN9924-3692 trial. The 
subject accidentally took the trial product 
 day and was thus treated with 20 mg of 
oral semaglutide.  The subject did not report any symptoms and treatment was continued without 
any change.

One case of accidental overdose has been reported in subjects treated with s.c. semaglutide once 
weekly. The subject inadvertently injected  mg of semaglutide instead of 0.4 mg, which 
corresponds to a 
-fold higher dose than the maximum dose included in that trial. After 
 hours 
the subject felt nauseated, vomited and had a headache. The subject was instructed to drink 
sufficient amounts of fluids. 
 and the subject 
wished to continue in the trial. No symptoms of hypoglycaemia or any other symptoms or signs 
were noted.  
For further details please see the current edition of the IB for oral administration of semaglutide 
(NN9924), edition 725, and any updates hereof.
For dulaglutide, see Section 18.1.2.
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 EAC is established to perform validation of selected AEs according to pre-
defined diagnostic criteria. The validation is based on review of pre-defined clinical data related to 
the specific AE. Pre-defined clinical data consist of copies of source documents collected and 
delivered by the investigational sites.
The EAC is composed of permanent members covering required medical specialities. EAC 
members must disclose any potential conflicts of interest and must be independent of Novo Nordisk. 
The events are reviewed by the EAC in a blinded manner. The EAC will have no authorisations to 
impact on trial conduct, trial protocol or amendments.
The EAC works in accordance with written guidelines included in the EAC Charter describing in 
details the composition, tasks, responsibilities and work processes of the committee.
The events outlined in Table 12–2 have been selected for adjudication in order to obtain an external 
independent validation of the diagnosis. In addition, cardiovascular events are being adjudicated 
according to U.S. Food and Drug Administration (FDA) requirements46.
The EAC will review copies in English (translated if necessary) of medical documentation received 
in the adjudication packages (e.g. x-rays, ECGs, ultrasound images, discharge summaries,

All AEs need to be assessed by the investigator if any AE category is applicable. If 
the AE category selected is in scope for adjudication, the event specific adjudication 
form in the eCRF will be populated for sites to complete
o
AEs with fatal outcome
!
Screening: 
o
All AEs will be screened by NN for potential missed events for adjudication and if 
needed, the investigator will be asked to provide additional information such as an 
alternative aetiology, underlying cause(s) and/or clinical details.
o
All ECGs will be centrally read. If the central reading conclusion is suggestive of 
new MI, the ECG adjudication form will be populated for sites to complete for all 
post-baseline ECGs.
!
EAC identified events:
o
The EAC can decide to have an AE adjudicated even if not initially reported as an 
event for adjudication by the investigator.
Event adjudication will be performed for AEs in randomised subjects including AEs with an onset 
date during the screening period. Event adjudication will not be performed for AEs in screening 
failures.
AEs for adjudication must be reported according to Section 12.2. In addition, the specific 
adjudication form should be completed within 14 calendar days of the investigator's first knowledge

13 Case report forms 
Novo Nordisk will provide a system for the eCRF. This system and support services to the system 
will be provided by an external supplier.
Ensure that all relevant questions are answered and that no empty data field exists. If a test or an 
assessment has not been done and will not be available, or if the question is irrelevant (e.g. is not 
applicable), indicate this according to the data entry instructions.
The following will be provided as paper case report forms (CRF):
!
Pregnancy forms
The following will be provided as paper CRFs to be used when access to the eCRF is revoked or if 
the eCRF is unavailable:
!
AE forms 
!
SIFs
!
Technical complaint forms (also to be used to report complaints that are not subject related [e.g. 
discovered at trial site before allocation]).
On the paper CRF forms print legibly, using a ballpoint pen. Ensure that all questions are answered 
and that no empty data blocks exist. Ensure that no information is recorded outside the data blocks. 
If a test/assessment has not been done and will not be available, indicate this by writing "ND" (not 
done) in the appropriate answer field in the CRF. If the question is irrelevant (e.g. is not applicable) 
indicate this by writing "NA" (not applicable) in the appropriate answer field. Further guidance can 
be obtained from the instructions in the CRF.
The investigator must ensure that all information is consistent with the source documentation. By 
electronically signing the case book in the eCRF, the investigator confirms that the information in 
the eCRF and related forms is complete and correct.
13.1
Corrections to case report forms 
Corrections to the eCRF data may be made by the investigator or the investigator's delegated staff. 
An audit trail will be maintained in the eCRF application containing as a minimum: the old and the 
new data, identification of the person entering the data, date and time of the entry and reason for the 
correction.
If corrections are made by the investigator's delegated staff after the date the investigator has signed 
the case book, the case book must be signed and dated again by the investigator.

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

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 eCRFs, the trial site's recruitment rate and the compliance 
of the trial site to the protocol and GCP, but will not exceed 12 weeks until LSLV at the trial site 
(for trial sites with active subjects [defined as subjects in screening, treatment or follow-up]).
The monitor must be given direct access to all source documents (original documents, data and 
records). Direct access includes permission to examine, analyse, verify and reproduce any record(s) 
and report(s) that are important to the evaluation of the trial. If the electronic medical record does 
not have a visible audit trail, the investigator must provide the monitor with signed and dated 
printouts. In addition the relevant trial site staff should be available for discussions at monitoring 
visits and between monitoring visits (e.g. by telephone).
All data must be verifiable in source documentation other than the eCRF.
For all data recorded the source document must be defined in a source document agreement at each 
trial site. There must only be one source defined at any time for any data element.
Source data generated by the trial site can be corrected by another person than the person entering 
the source data; any correction must be explained, signed and dated by the person making the 
correction.
The original of the completed diaries and/or PROs must not be removed from the trial site, unless 
they form part of the eCRF and a copy is kept at the site.
The monitor will ensure that the eCRFs are completed and that paper CRFs are collected.
The following data will be source data verified for screening failures:
!
Date for obtaining informed consent.
!
Reason for screening failure
Monitors will review the subject's medical records and other source data (e.g. the diaries and PROs) 
to ensure consistency and/or identify omissions compared to the eCRF. If discrepancies are found, 
the investigator must be questioned about these.
A follow-up letter (paper or electronic) will be sent to the investigator following each monitoring 
visit. This should address any action to be taken.

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

17 Statistical considerations
General considerations
If necessary, a statistical analysis plan (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.
The blinding of the randomised dose level for semaglutide arms will be maintained until the 
database has been released for statistical analysis. No interim analyses will be performed before the 
database is locked.
Data from all sites will be analysed and reported together.
In statistical analyses where stratification is included, the background OAD medication at screening 
(SU, glinide, TZD, α-GI or SGLT-2 inhibitor) will be included based on the actual information 
collected through the eCRF. In case of missing eCRF information the information collected from 
the IWRS system will be used. In the statistical analyses the stratification factor will refer to 
background OAD medication at screening.
The latest available measurement, at or prior to the randomisation visit, will be used as the baseline 
measurement. If no measurement(s) have been obtained, at or prior to randomisation, the baseline 
value will be left missing.
Laboratory values below the lower limit of quantification (LLoQ) will be set to ½LLoQ. Number of 
values below LLoQ by treatment and visit will be summarised if deemed relevant.
Results from a statistical analysis will as a minimum be presented by the estimated treatment 
contrasts for the below three comparisons with associated two-sided 95% confidence intervals and
p-values corresponding to two-sided tests of no difference with no multiplicity adjustments:
!
oral semaglutide 14 mg vs. dulaglutide 0.75 mg
!
oral semaglutide 7 mg vs. dulaglutide 0.75 mg
!
oral semaglutide 3 mg vs. dulaglutide 0.75 mg
If no statistical analysis is specified, data will be presented using relevant summary statistics.
The two different estimands defined below will be used for the evaluation of the efficacy endpoints.

Primary and secondary estimands
Two estimands addressing different aspects of the trial objective will be defined; a primary de-facto
(effectiveness) estimand and a secondary de-jure (efficacy) estimand:
!
Primary estimand
o
de-facto treatment difference (oral semaglutide versus dulaglutide) at week 26 for all 
randomised subjects regardless of adherence to randomised treatment and initiation 
of rescue medication
The primary de-facto estimand assesses the expected glycaemic benefit in a future population that 
results from subjects initiating treatment with oral semaglutide including potential rescue 
medication(s). Generalisation of this estimand depends among other things on the extent to which 
the use of rescue medication in this trial reflects clinical practice and the treatment adherence 
reflects the behaviour of the target population. Accordingly, data collected regardless of 
discontinuation of trial product or initiation of rescue medication(s) will be used to draw inference.
!
Secondary estimand
o
de-jure treatment difference (oral semaglutide versus dulaglutide) at week 26 for all 
randomised subjects if all subjects adhered to treatment and did not initiate rescue 
medication
The secondary de-jure estimand assesses the glycaemic benefit a future subject is expected to 
achieve if initiating and continuing treatment with oral semaglutide. It is considered a clinically 
relevant estimand as it provides information to treating clinicians about the expected glycaemic 
efficacy of oral semaglutide for purposes of treating individual subjects. Generalisation of this 
estimand depends among other things on the extent to which the adherence to trial product 
administration in this trial reflects the behaviour of the target population. Accordingly, only data 
collected prior to discontinuation of trial product or initiation of rescue medication will be used to 
draw inference. This will avoid confounding from rescue medication.
Missing data consideration
Based on the results from similar Japanese phase 3 trials investigating liraglutide and s.c. 
semaglutide in combination with one OAD (NN2211-3924 and NN9535-4091) and the oral 
semaglutide phase 2 trial (NN9924-3790), it is expected that maximum 20% of the subjects will 
discontinue trial product or withdrawal from the trial at week 52. 
The primary efficacy results will be evaluated at week 26. This approach will result in a lower 
proportion of missing data, use of rescue medication and premature treatment discontinuation, 
compared to the expected proportion at week 52. For the primary estimand, data collected 
regardless of discontinuation of trial product or initiation of rescue medication(s) will be used to 
draw inference, missing data will therefore mainly be due to withdrawal from trial or lost to follow-

up. When estimating the secondary estimand, the proportion of missing data is expected to be 
higher compared to the primary estimand, since data collected after discontinuation of trial product 
or initiation of rescue medication(s) will be set to missing as well. 
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 sample size of this trial was determined based on a requirement of the draft AD guideline28.
A total of 455 subjects will be randomised in a 2:2:2:1 manner to receive either a dose of 3, 7 or 14 
mg of oral semaglutide or of 0.75 mg dulaglutide. Randomisation will be stratified by background 
OAD medication at screening (SU, glinide, TZD, α-GI or SGLT-2 inhibitor) with the additional 
requirement of 147 subjects on SU and 77 subjects on each of the other four background OAD 
medications. It is expected that maximum 20% of the subjects will discontinue trial product or 
withdrawal from the trial at week 52. Therefore, at least 100 completers in combination with SU 
and 50 completers in combination with each of other OAD monotherapies (glinide, TZD, α-GI or 
SGLT-2 inhibitor) on oral semaglutide (3, 7 or 14 mg) are expected.
17.2
Definition of analysis sets
The following analysis sets will be defined:
Full analysis set (FAS): Includes all randomised subjects. Subjects in the FAS will contribute to 
the evaluation “as randomised”.
Safety analysis set (SAS): Includes all subjects exposed to at least one dose of trial product. 
Subjects in the SAS will contribute to the evaluation based on the trial product received for the 
majority of the period where they were on treatment. This will be referred to as contributing to the 
evaluation “as treated”.
Data selections and observation periods
Unless subjects withdraw their informed consent, data collection will continue for the full duration 
of the trial. The full duration of the trial is defined as up to and including:
!
the follow-up visit (V14) for subjects on trial product
!
the latest occurring visit of the end-of-treatment visit (V13) or the follow-up premature 
discontinuation visit (V14A), for subjects who have discontinued trial product prematurely
Subjects and data to be used in an analysis will be selected in a two-step manner:
!
Firstly, subjects will be selected based on the specified analysis set
!
Secondly, data points on the selected subjects from first step will be selected based on the 
specified observation period

Definition of the observation periods
In-trial: This observation period represents the time period where subjects are considered to be in 
the trial, regardless of discontinuation of trial product or initiation of rescue medication. The in-trial 
observation period starts at randomisation (as registered in IWRS) and ends at the date of:
!
the last direct subject-site contact, which is scheduled to take place 5 weeks after planned last 
dose of trial product at a follow-up visit
!
withdrawal for subjects who withdraw their informed consent
!
the last subject-investigator contact as defined by the investigator for subjects who are lost to 
follow-up
!
death for subjects who dies before any of the above
On-treatment: This observation period represents the time period where subjects are considered 
treated with trial product. The observation period is a subset of the in-trial observation period. It 
starts at the date of first dose of trial product. Two slightly different end dates will be needed to 
cover all assessments appropriately. For adjudicated events, ECGs and AEs including 
hypoglycaemic episodes, the observation period ends at the first date of any of the following:
!
the follow-up visit (V14)
!
the follow-up prematurely discontinuation visit (V14A)
!
the last date on trial product + 38 days
!
the end-date for the in-trial observation period
The follow-up visit is scheduled to take place 5 weeks after the last date on trial product 
corresponding to approximately five half-lives of oral semaglutide. The visit window for the follow-
up visit is +3 days.
For efficacy and other safety assessments (laboratory assessments, physical examination and vital 
signs) the observation period ends at the last date on trial product +3 days. This will be used in 
order to ensure specificity to reversible effects of treatment.
On-treatment without rescue: This observation period is a subset of the on-treatment observation 
period, where subjects are considered treated with trial product, but have not initiated any rescue 
medications. Specifically it starts at date of first dose of trial product and the observation period 
ends at the first date of:
!
the last dose of trial product + 3 days
!
initiation of rescue medication
The in-trial observation period will be the primary observation period for estimating the primary 
estimand. The on-treatment without rescue medication observation period will be the primary 
observation period when estimating the secondary estimand. The on-treatment observation period 
will be considered supportive for evaluating efficacy. Safety will be evaluated based on the in-trial 
and the on-treatment observation periods.

Data points collected outside an observation period will be treated as missing in the analysis. 
Baseline data will always be included in an observation period. For adjudicated events, the onset 
date will be the EAC adjudicated onset date.
Before data are locked for statistical analysis and the randomisation code is broken, a review of all 
data will take place. Any decision to exclude either a subject or single observations from the 
statistical analysis is the joint responsibility of the members of the Novo Nordisk study group. 
Exclusion of data from analyses should be used restrictively, and normally no data should be 
excluded from the FAS. The subjects or observations to be excluded, and the reasons for their 
exclusion must be documented and signed by those responsible before database lock. The subjects 
and observations excluded from analysis sets, and the reason for this, will be described in the 
clinical trial report.
17.3
Primary endpoint
The primary endpoint is number of TEAEs during exposure to trial product, assessed up to 
approximately 57 weeks
All AEs will be coded using the most recent version of the Medical Dictionary for Regulatory 
Activities (MedDRA) coding.
A treatment-emergent AE is defined as an AE with onset in the on-treatment observation period 
(see definition of observation periods in Section 17.2). The evaluation will be based on SAS.
TEAEs will be summarised in terms of the number of subjects with at least one event (N), the 
percentage of subjects with at least one event (%), the number of events (E) and the event rate per 
100 patient years of observation time (R) for the on-treatment observation period. Supportive 
summaries of AEs will be made for the in-trial observation period. The development over time in 
gastrointestinal AEs will be presented graphically. 
Furthermore summary tables based on system organ class and preferred term are made for

Efficacy endpoints
The below supportive secondary efficacy endpoints will be analysed based on FAS using:
!
The in-trial observation period
!
The on-treatment without rescue medication observation period.
Change from baseline to week 26 in HbA1c
The primary estimand will be estimated based on the FAS using week 26 measurements from the 
in-trial observation period. The primary statistical analysis will be a pattern mixture model using 
multiple imputation to handle missing data assuming that the missing data mechanism is missing at 
random (MAR) within the groups used for imputation. Imputation of missing data at week 26 will 
be done within 8 groups of subjects defined by randomised treatment arm, and whether subjects at 
week 26 (i) have discontinued treatment or initiated rescue medication or (ii) are still on treatment 
and have not initiated rescue medication. It is hereby assumed that the likely values of what the 
missing data would have been if available are best described by information from subjects who at 
week 26 are similar in terms of randomised treatment arm and treatment adherence/rescue status.
Missing values for each group will be imputed as follows:
!
An analysis of covariance (ANCOVA) with stratification factor 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 stratification factor as categorical and baseline 
HbA1c. Thus, 100 complete data sets will be generated including observed and imputed values.
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 and stratification factor as categorical fixed effects and 
baseline HbA1c as a covariate. The results obtained from analysing the datasets will be combined 
using Rubin’s rule48 to draw inference.
The secondary estimand will be estimated based on the FAS using post-baseline measurements up 
to and including week 26 from the on-treatment without rescue medication observation period. The 
secondary analysis 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 and stratification factor as categorical 
fixed effects and baseline HbA1c as a covariate, all nested within visit. An unstructured covariance

matrix for HbA1c measurements within the same subject will be employed, assuming measurements 
from different subjects are independent.
The MMRM is a well-established method that accounts for the uncertainty pertaining to missing 
data. This analysis assumes that the missing data mechanism is MAR. Under this assumption the 
statistical behaviour of the missing data (given the observed responses and model fixed effects and 
covariates) is assumed to be same as the observed data.

Change from baseline to week 26 and week 52 in the below derived endpoints from the 7-point 
SMPG profile:
!
Mean 7-point profile,defined as the area under the profile, calculated using the trapezoidal 
method, divided by the measurement time

Mean postprandial increment over all meals
The above continuous endpoints will be analysed separately using similar model approaches as for 
change from baseline to week 26 in HbA1c with the associated baseline response as a covariate. 
Fasting lipid profile endpoints will be log-transformed prior to analysis with the associated log-
transformed baseline value as a covariate.
For evaluation of the primary estimand the analysis will be performed separately for week 26 and 
52. For the analysis at week 52, 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 groups of subjects 
instead of the 8 groups as described for the week 26 evaluation above. If less than 5 subjects have

available data in one of the 16 groups, the imputation will be made within the 8 groups specified for 
the primary evaluation.
For evaluation of the secondary estimand the MMRM will include all scheduled post-baseline 
measurement up to and including week 52. From this model the estimated treatment differences 
(ratios) will be presented at week 26 and week 52 with 95% confidence intervals and two-sided p-
values for test of no difference.
The frequency of missing data is expected to be slightly larger at week 52 compared to week 26. 
The rate of missing data is expected to decline over time.
Binary efficacy endpoints
If a subjects after week 26 and 52 achieves (yes/no):
!
HbA1c < 7.0% (53 mmol/mol) (ADA target)
!
HbA1c ≤ 6.5% (48 mmol/mol) (AACE target)
!
HbA1c reduction ≥ 1%-point (10.9 mmol/mol)
!
Body weight loss ≥ 3% 
!
Body weight loss ≥ 5% 
!
Body weight loss ≥ 10% 
!
HbA1c < 7.0% (53 mmol/mol) without hypoglycaemia (treatment-emergent severe or BG-
confirmed symptomatic hypoglycaemic episodes) and no body weight gain 
!
HbA1c reduction ≥ 1%-point (10.9 mmol/mol) and body weight loss ≥ 3%
The above eight binary endpoints will be analysed separately using a logistic regression model with 
treatment and stratification factor as fixed effects and baseline response as covariate (i.e. baseline 
HbA1c for binary HbA1c endpoints, baseline weight for weight endpoints and both baseline HbA1c
and baseline weight for the binary endpoints that combines both parameters). To account for 
missing data, the analysis will be made using a sequential multiple imputation approach as 
described below:
!
Multiple imputed data sets (100) will be created in which missing values for the underlying 
continuous assessments are imputed by treatment group and treatment adherence/rescue status 
assuming MAR and as described above for the primary analysis for change in HbA1c and by 
treatment group assuming MAR and as described above for the secondary analysis for change in 
HbA1c.

The binary endpoint will be created for each of the 100 complete data sets

Each of the created complete data set will be analysed with the logistic model and inference will

The endpoint will be analysed based on FAS using both the on-treatment observation period and the 
in-trial observation period. For the analysis based on the on-treatment observation period, subject 
without need for rescue medication during the on-treatment observation period will be censored at 
the time point of the date of last trial product. For the in-trial period subject without need for 
addition of glucose-lowering medication during the in-trial observation period, will be censored at 
the time point of the date of end of the in-trial observation period. For this analysis, the follow-up 
period will be excluded from the in-trial observation period, since subjects will have to stop 
treatment at the end-of-treatment visit and therefore might need addition of glucose-lowering 
medication during the follow-up period.
The endpoint will be described and compared for each of the oral semaglutide dose level versus 
dulaglutide 0.75 mg using likelihood ratio tests obtained from a Cox proportional hazards model. 
From this analysis the estimated hazard ratios between each dose levels and versus dulaglutide 0.75 
mg will be presented together with 95% confidence intervals and two-sided p-values for test of no 
difference.

Treatment-emergent severe or BG-confirmed symptomatic hypoglycaemic episodes during

Classification of hypoglycaemia: 
Hypoglycaemic episodes will be summarised for the SAS and the on-treatment observation period 
only.
Treatment emergent: hypoglycaemic episodes will be defined as treatment-emergent if the onset of 
the episode occurs within the on-treatment observation period (see definition of observation periods 
in Section 17.2).
Nocturnal hypoglycaemic episodes: episodes occurring between 00:01 and 05.59 both inclusive.
Hypoglycaemic episodes are classified according to the Novo Nordisk classification of 
hypoglycaemia and the ADA classification of hypoglycaemia (see Figure 17–1).
Novo Nordisk classification of hypoglycaemia
In normal physiology, symptoms of hypoglycaemia occur below a PG level of 3.1 mmol/L 
(56 mg/dL)49. 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 classification41 or BG confirmed by a PG value < 3.1 mmol/L (56 mg/dL) with 
symptoms consistent with hypoglycaemia.

ADA classification41 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.

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

Benefit-risk assessment of the trial
18.1.1
Risks and precautions with oral semaglutide
The nonclinical safety programme of oral semaglutide has not revealed any safety issues precluding 
use in humans. 
The sections below describe the important identified and potential risks and precautions associated 
with oral semaglutide treatment. These are based on findings in nonclinical studies and clinical 
trials with oral semaglutide as well as other GLP-1 RAs. For each of these risks and precautions, 
mitigating actions have been implemented to minimise the risks for subjects enrolled in this trial.
Identified risks
Gastrointestinal adverse events
Consistent with findings with other GLP-1 RAs, the most frequently reported AEs in clinical trials 
with oral semaglutide have been gastrointestinal disorders (nausea, vomiting, diarrhoea, dyspepsia 
and constipation). Clinical trials have indicated that a low starting dose and gradual dose escalation 
mitigates the risk of gastrointestinal AEs. Consequently, a low starting dose and dose escalation 
with 4 week dose-escalation steps have been implemented in the trial. 
Potential risks
Medullary thyroid cancer
The human relevance of the proliferative C-cell changes found in rodents treated with GLP-1 RAs 
is unknown, but data suggest that rodents are more sensitive to the mode of action of GLP-1 RAs 
for induction of C-cell tumours. However, as a precaution, subjects with a family or personal 
history of MEN 2 or MTC will not be enrolled in the trial. During the trial, calcitonin will be 
measured on a regular basis, and the guidance for investigators on further evaluation and action on 
elevated calcitonin concentrations is included in appendix A. 
Acute pancreatitis
Acute pancreatitis has been reported in subjects treated with GLP-1 RAs including oral semaglutide. 
As a precaution, subjects with a history of acute or chronic pancreatitis will not be enrolled in the 
trial. Also, subjects will be informed about the symptoms of acute pancreatitis and serum levels of 
lipase and amylase will be monitored throughout the trial.
Pancreatic cancer
Patients with T2DM have an increased risk of certain types of cancer such as pancreatic cancer. 
There is currently no support from nonclinical studies or clinical trials or post-marketing data that

GLP-1-based therapies increase the risk of pancreatic cancer. However, pancreatic cancer has been 
included as a separate potential risk due to the scientific debate surrounding a potential association 
to GLP-1-based therapies and the unknown long-term effects of stimulation of β-cells and 
suppression of α-cells. Pancreatic cancer has been classified as a potential class risk of GLP-1 RAs 
by EMA.
Allergic reactions
As in the case with all protein-based pharmaceuticals, treatment with oral semaglutide may evoke 
allergic reactions. These may include urticaria, rash, pruritus as well as anaphylactic reactions. As a 
precaution, subjects with known or suspected hypersensitivity to trial product(s) or related products 
will not be enrolled in the trial. In addition, subjects will be instructed to contact the site staff as 
soon as possible for further guidance if suspicion of a hypersensitivity reaction to the trial product 
occurs.
Hypoglycaemia
Based on current knowledge about the GLP-1 RA drug class, there is a risk of hypoglycaemic 
episodes. Hypoglycaemic episodes have mainly been observed when a GLP-1 RA is combined with 
sulphonylurea or insulin. The risk for development of hypoglycaemia with oral semaglutide in 
combination with sulphonylurea and insulin is currently unknown. 
Acute renal impairment
In subjects treated with GLP-1 RAs, including oral semaglutide, gastrointestinal AEs such as 
nausea, vomiting and diarrhoea may lead to significant dehydration and secondary acute renal 
impairment. Subjects with gastrointestinal AEs are recommended to drink plenty of fluids to avoid 
volume depletion. Also, serum creatinine and other markers of kidney function will be monitored 
throughout the trial.
SGLT-2 inhibitors, an allowed background OAD medication, have also been associated with 
volume depletion. It is recommended to monitor renal function and for signs and symptoms of fluid 
loss during therapy. Severe dehydration may be a risk factor for ketoacidosis.
Impaired renal function may increase the risk of metformin-associated lactic acidosis when GLP-1 
RAs are co-administered with metformin. In case subject is treated with metformin as a rescue 
medication and experiences prolonged or severe nausea and vomiting, the investigator should 
monitor serum creatinine, and if clinically indicated, withhold metformin until resolution of renal 
dysfunction.
If a subject experiences persistent decline in renal function on background OAD medication and/or 
rescue medication, the background OAD medication and/or rescue medication should be
adjusted/discontinued at invetigator’s discretion and in accordance with the current apporoved label
or guideline.

Other safety considerations
Diabetic retinopathy
A transient worsening of diabetic retinopathy is a recognised complication in selected patients with 
diabetes after initiation of intensive antidiabetic treatment50,51,52. 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 progression4,53 even in intensively treated patients who experienced early worsening51. 
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 placebo. 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.
Teratogenicity (embryo-foetal development toxicity)
Semaglutide caused embryo-foetal malformations in the rat through a GLP-1 receptor mediated 
effect on the inverted yolk sac placenta leading to impaired nutrient supply to the developing 
embryo. Primates do not have an inverted yolk sac placenta which makes this mechanism unlikely 
to be of relevance to humans. However, as a precaution, females who are pregnant, breast-feeding 
or intend to become pregnant or are of childbearing potential and not using an adequate 
contraceptive method will not be enrolled in the trial. In addition, pregnancy tests will be performed 
at all visits, including screening and follow-up and at any time during the trial if a menstrual period 
is missed.
General precautions
All subjects will be included after a thorough evaluation with regards to in- and exclusion criteria 
defined in order to ensure that subjects are eligible for trial treatment. There are also strict 
glyacemic rescue criteria in place to ensure acceptable glycaemic control during the trial. If rescue 
medication is required, it should be in accordance with ADA/European Association for the Study of 
Diabetes29,30 (excluding GLP-1 RAs, DPP-4 inhibitors and amylin analogues).
It is the responsibility of the investigator to ensure the best possible care according to clinical 
practice in Japan and/or the principles outlined in Diabetes Care 2016 Standards of Medical Care in 
Diabetes54.
Further details with regards to safety of trial product are described in the current edition of the IB 
for oral semaglutide (NN9924)25, or any updates theretof.

Being a GLP-1 RA dulaglutide shares many of the same potential risks for the subject as oral
semaglutide. Please consult the EU SmPC26 and the local prescribing information for dulaglutide 
for the following information on warnings and precautions/risks gathered under clinical trials and 
from post marketing data: thyroid C-cell tumours, acute pancreatitis, hypoglycaemia, 
hypersensitivity, severe gastrointestinal disease.
Overdoses have been reported in clinical studies. Effects associated with these overdoses were 
primarily mild or moderate gastrointestinal events (e.g., nausea, vomiting) and nonsevere
hypoglycaemia. In the event of overdose, appropriate supportive care (including frequent plasma 
glucose monitoring) should be initiated according to the subject’s clinical signs and symptoms.
18.1.3
Benefits
In this trial subjects will be randomised to one of four treatment arms involving an active add-on
treatment regimen anticipated to be more efficacious than the treatment they receive at the time of 
trial entry (background OAD medication). 
Based on the results of the phase 2 dose finding trial, oral semaglutide is expected to provide 
clinically relevant improvements in glycaemic control and body weight in subjects with T2DM.
In addition, it is expected that all subjects will benefit from participation through close contact with 
the trial site, with close follow-up of their T2DM and a careful medical examination; all of which 
will most likely result in an intensified management of their T2DM.
All subjects in this trial will receive trial products and auxiliary supplies free of charge.
18.1.4
Risk and benefit conclusion 
The safety profile for oral semaglutide generated from the clinical and nonclinical development 
programme has not revealed any safety issues that would prohibit administration of oral 
semaglutide in accordance with the planned clinical trial.
The phase 2 results indicate that oral semaglutide will provide clinically relevant improvements in 
glycaemic control and body weight.
Dulaglutide is already a marketed drug approved for the use in subjects with T2DM.
Safety and efficacy will be monitored regularly and acceptable glycaemic control will be reinforced 
at all times during the trial.
In conclusion, the potential risk to the subjects in this trial is considered low and acceptable in view 
of the anticipated benefits oral semaglutide/dulaglutide would provide to subjects with T2DM.

19 Protocol compliance
19.1
Protocol deviations
Deviations from the protocol should be avoided.
If deviations do occur, the investigator must inform the monitor and the implications of the 
deviation must be reviewed and discussed.
Deviations must be documented and explained in a protocol deviation by stating the reason, date 
and the action(s) taken. Some deviations, for which corrections are not possible, can be 
acknowledged and confirmed via edit checks in the eCRF or via listings from the trial database. 
Documentation on protocol deviations must be kept in the investigator trial master file and sponsor 
trial master file.
19.2
Prevention of missing data
The importance of subject retention will be addressed by Novo Nordisk in the training and 
communication with the trial sites. 
The subjects will be carefully informed about the trial procedures before signing informed consent, 
so that they know the implications of participating in the trial.  
Close surveillance of subject retention will be performed throughout the trial by Novo Nordisk with 
focus on reasons for premature discontinuation of trial product or withdrawal of consent to secure 
early mitigations in collaboration with the trial sites. 
The investigator will make every effort to ensure that all assessments are performed and data is 
collected. If missing data does occur the reason will be collected via the protocol deviation process, 
see Section 19.1. Novo Nordisk will monitor protocol deviations on an on-going basis throughout 
the trial followed by appropriate actions (e.g. re-training of site staff).

22 Responsibilities
The investigator is accountable for the conduct of the trial at his/her site and must ensure adequate 
supervision of the conduct of the trial at the trial site. If any tasks are delegated, the investigator 
must maintain a log of appropriately qualified persons to whom he/she has delegated specified trial-
related duties. The investigator must ensure that there is adequate and documented training for all 
staff participating in the conduct of the trial. It is the investigator’s responsibility to supervise the 
conduct of the trial and to protect the rights, safety, and well-being of the subjects.
A qualified physician, who is an investigator or a sub-investigator for the trial, must be responsible 
for all trial-related medical decisions.
The investigator will follow instructions from Novo Nordisk when processing data.
The investigator is responsible for filing essential documents (i.e. those documents which 
individually and collectively permit evaluation of the conduct of a trial and the quality of the data 
produced) in the investigator trial master file. The documents including the subject identification 
code list must be kept in a secure locked facility, so no unauthorized persons can get access to the 
data. 
The investigator will take all necessary technical and organisational safety measures to prevent 
accidental or wrongful destruction, loss or deterioration of data. The investigator will prevent any 
unauthorised access to data or any other processing of data against applicable law. The investigator 
must be able to provide the necessary information or otherwise demonstrate to Novo Nordisk that 
such technical and organisational safety measures have been taken.
During any period of unavailability, the investigator must delegate responsibility for medical care of 
subjects to a specific qualified physician who will be readily available to subjects during that time.
If the investigator is no longer able to fulfil the role as investigator (e.g. if he/she moves or retires), 
a new investigator will be appointed in consultation with Novo Nordisk. 
The investigator and other site personnel must have sufficient English skills according to their 
assigned task(s).

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 publications55.
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 Disclosure31.
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 Editors55 (sometimes referred to as the Vancouver 
Criteria). Novo Nordisk will appoint investigator(s) to prepare publications in collaboration with 
Novo Nordisk.
23.1.2
Site-specific publication(s) by investigator(s)
For a multi-centre clinical trial, analyses based on single-site data usually have significant statistical 
limitations and frequently do not provide meaningful information for healthcare professionals or 
subjects, and therefore may not be supported by Novo Nordisk. It is a Novo Nordisk policy that 
such individual reports do not precede the primary manuscript and should always reference the 
primary manuscript of the trial.
Novo Nordisk reserves the right to prior review of such publications. Further to allow for the 
primary manuscript to be published as the first, Novo Nordisk asks for deferment of publication of 
individual site results until the primary manuscript is accepted for publication. As Novo Nordisk 
wants to live up to the industry publication policy, submission of a primary publication will take 
place no later than 18 months after trial completion.
23.2
Investigator access to data and review of results
As owner of the trial database, Novo Nordisk has the discretion to determine who will have access 
to the database. 
Individual investigators will have their own research subjects' data, and will be provided with the 
randomisation code after results are available.

24 Retention of clinical trial documentation and human biosamples
24.1
Retention of clinical trial documentation
Subject’s medical records must be kept for the maximum period permitted by the hospital, 
institution or private practice.
The investigator must agree to archive the documentation (this includes both electronic and paper-
based records) pertaining to the trial in an archive after completion or discontinuation of the trial if 
not otherwise notified. The investigator should not destroy any documents without prior permission 
from Novo Nordisk. If the investigator cannot archive the documents at the trial site, Novo Nordisk 
can refer the investigator to an independent archive provider that has a system in place to allow only 
the investigator to access the files.
The investigator must be able to access his/her trial documents without involving Novo Nordisk in 
any way. Site-specific CRFs and other subject data (in an electronic readable format or as paper 
copies or prints) will be provided to the investigator before access is revoked to the systems and/or 
electronic devices supplied by Novo Nordisk. These data must be retained by the trial site. If the 
provided data (e.g. the CD-ROM) is not readable during the entire storage period, the investigator 
can request a new copy. A copy of all data will be stored by Novo Nordisk.
Novo Nordisk will maintain Novo Nordisk documentation pertaining to the trial for at least 20 years 
after discontinuation of the marketing authorisation, termination of the trial or cancellation of the 
research project whichever is longest.
The files from the trial site/institution must be retained for 15 years after end of trial as defined in 
Section 7, or longer if required by local regulations or Novo Nordisk. In any case trial files cannot 
be destroyed until the trial site/institution is notified by Novo Nordisk. The deletion process must 
ensure confidentiality of data and must be done in accordance with local regulatory requirements.
24.2
Retention of human biosamples
Hypersensitivity samples (anti-semaglutide IgE antibodies and anti-semaglutide binding antibodies; 
see appendix B) may be retained for later analysis for further characterisation of antibody responses 
towards drug if required by health authorities or for safety reasons.
The samples will be stored at a central bio-repository after end of trial and until marketing 
authorisation approval or until the research project terminates, but no longer than 15 years from end 
of trial after which they will be destroyed.
The subject’s identity will remain confidential and the antibody samples will be identified only by 
subject number, visit number and trial identification number. No direct identification of the subject 
will be stored together with the samples.

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

Background
Treatment with GLP-1 receptor agonists has shown to be associated with thyroid C-cell changes in 
rodents but not in non-human primates. The human relevance of this finding is unknown. However, 
based on the findings in rodents, monitoring of serum calcitonin (a sensitive biomarker for C-cell 
activation) is currently being performed in clinical trials with semaglutide.
While there is general agreement on the clinical interpretation of substantially elevated calcitonin 
levels (greater than 100 ng/L) as likely indicative of C-cell neoplasia, the interpretation of values 
between upper normal range (5.0 and 8.4 ng/L for women and men, respectively) and 100 ng/L is 
less clear with regards to indication of disease.
There are several known confounding factors affecting calcitonin levels, e.g.:
!
Renal dysfunction
!
Smoking
!
Autoimmune thyroiditis
!
Several drug classes (e.g. proton pump inhibitors, beta-blockers, H2-blockers and 
glucocorticoids)
Physiology of C-cell activation in various clinical conditions and in different patient populations 
(i.e. with various co-morbidities) is poorly understood. There may be various clinical conditions not 
identified so far which mildly or moderately affect calcitonin secretion by C-cells.

Calcitonin monitoring
A blood sample will be drawn at pre-specified trial visits for measurement of calcitonin.
In case a subject has a calcitonin value ≥ 10 ng/L the algorithm outlined in Figure 1 and described 
below should be followed. The algorithm applies for all calcitonin values in the trial.
Calcitonin < 10ng/L
Calcitonin  ≥ 10 ng/L and 
< 50 ng/L
Calcitonin  ≥ 50 ng/L and 
< 100 ng/L
Calcitonin  ≥ 100 ng/L

discontinuation of trial product). The subject should remain in the trial, however, all medications 
suspected to relate to this condition must be discontinued until diagnosis has been established.
Background: These values were found in 9 (0.15%) of a population of 5817 patients with thyroid 
nodular disease1. All of these patients were diagnosed with medullary thyroid carcinoma (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 multiple endocrine neoplasia type 2 (MEN2) and perform a genetic test for RET 
(re-arranged during transfection) proto-oncogene mutation.
2.2
Calcitonin ≥ 50 and < 100 ng/L
Action: The subject should be referred to a thyroid specialist for further evaluation. The subject 
should remain in the trial and continuation on trial product should be based on the evaluation done 
by the thyroid specialist. 
Background: These values were found in 8 (0.14%) of the population of 5817 patients with thyroid 
nodular disease1. Two of these subjects were diagnosed with MTC and two were diagnosed with 
C-cell hyperplasia, resulting in a positive predictive value of a C-cell anomaly of 50%.
Diagnostic evaluation should include: 
!
Thyroid ultrasound examination 
!
If available and there are no contraindication, a pentagastrin stimulation test should be done. For 
subjects with positive pentagastrin stimulation test, surgery should be considered
!
If pentagastrin stimulation test is not available, thyroid ultrasound and fine needle aspiration 
biopsy may add important clinical information about the need for surgery
2.3
Calcitonin ≥ 10 and < 50 ng/L
Action: The subject can continue in the trial on trial product. Continue sampling of calcitonin 
according to the protocol.
If the value is from the last sample taken in the trial, the subject should be referred to a thyroid 
specialist for further evaluation.

Background: Calcitonin values from 20-50 ng/L were found in up to 1% of subjects of the 
population of 5817 patients with thyroid nodular disease1. The predictive value of a C-cell anomaly 
for this calcitonin level was 8.3%. However, the likelihood of having a medullary carcinoma > 1 cm 
with calcitonin in this range is extremely low.
For calcitonin values between 10-20 ng/L Costante et al1 identified 216 (3.7%) patients. One patient 
out of the 216 had a subsequent basal (unstimulated) calcitonin of 33 ng/L, and had C-cell 
hyperplasia at surgery. Two other studies used a cut-off of calcitonin > 10 ng/L to screen for C-cell 
disease, but they do not provide sufficient information on patients with basal calcitonin > 10 and 
< 20 ng/L to allow conclusions2,3.

Medication error (concerning trial products):
!
Administration of wrong drug or use of wrong device.
Note: Use of wrong dispensing unit number (DUN) is not considered a medication error
unless it results in administration of wrong drug.
!
Wrong route of administration, such as intramuscular instead of s.c.
!
Administration of an overdose with the intention to cause harm (e.g. suicide attempt), 
misuse or abuse of trial product
!
Accidental administration of a higher dose than intended. A higher dose of semaglutide is a 
dose of at least one tablet more than the intended dose, and for dulaglutide a higher dose 
than 0.75 mg/day; 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 upper normal limit (UNL)
!
Hepatic event defined as:
!
alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 5x UNL and total 
bilirubin ≤ 2x UNL
!
ALT or AST > 3x UNL and total bilirubin > 2x UNL*
!
Hepatic event leading to trial product discontinuation 
*Please note that in case of a hepatic event defined as ALT or AST >3 x UNL and total bilirubin 
>2x UNL, where no alternative aetiology exists (Hy's law), this must be reported as a serious 
adverse event (SAE) using the important medical event criteria if no other seriousness criteria are

1.4.1
Assessments in case of suspicion of acute pancreatitis
Most patients with acute pancreatitis experience severe abdominal pain that is located generally in 
the epigastrium and radiates to the back. The onset of the pain may be swift reaching maximum 
intensity within 30 min, it is frequently unbearable and characteristically persists for more than 24 
hours without relief1. The pain is often associated with nausea and vomiting. Physical examination 
usually reveals severe upper abdominal tenderness at times associated with guarding. 
In general, both amylase and lipase are elevated during the course of acute pancreatitis. The serum 
lipase may remain elevated slightly longer than amylase. The level of the serum amylase and/or 
lipase does not correlate with the severity of acute pancreatitis1. In general, serum lipase is thought 
to be more sensitive and specific than serum amylase in the diagnosis of acute pancreatitis. 
In case of suspicion of acute pancreatitis, the trial product should promptly be interrupted (no 
treatment discontinuation call should be made in the interactive web response system (IWRS)
before diagnosis of acute pancreatitis is confirmed). Appropriate additional examinations must be 
performed, including local measurement of amylase and lipase. 
The diagnosis of acute pancreatitis requires two of the following three features2: 
!
abdominal pain consistent with acute pancreatitis (acute onset of a persistent, severe, epigastric 
pain often radiating to the back)
!
serum lipase activity (and/or amylase activity) at least three times greater than the UNL
!
characteristic findings of acute pancreatitis on imaging
If acute pancreatitis is ruled out, trial product should be re-initiated.
If acute pancreatitis is confirmed, appropriate treatment and careful monitoring of the subject 
should be initiated. The subject must be discontinued from trial product (treatment discontinuation 
call), but should remain in the trial (see protocol Section 6.5 and 8.1.6).

1.8.1
Assessments in case of suspicion of hypersensitivity reaction
In case of suspicion of a severe immediate systemic hypersensitivity reaction3 to the trial product, 
the subject must be discontinued from trial product but should remain in the trial (see protocol
Section 6.5 and 8.1.6).
If suspicion of a hypersensitivity reaction occurs, the subjects should be instructed to contact the 
site staff as soon as possible for further guidance.
To assist in the diagnostic evaluation it is recommended to draw a blood sample for measurement of 
tryptase (total and/or mature tryptase, local assessment) within 3 hours of onset of the 
hypersensitivity reaction, and if this is achieved, a tryptase sample should also be drawn at V14A. 
Furthermore, a blood sample for assessment of anti-semaglutide IgE antibodies and anti-
semaglutide binding antibodies should be drawn as soon as possible after the event and at V14A 
and sent to central laboratory. Tryptase concentrations, if available, should be included in the 
specific event form when reporting the AE.
In case of suspicion of immune complex disease, the subject must be discontinued from trial 
product but should remain in the trial (see protocol Section 6.5 and 8.1.6). It is recommended to 
draw a blood sample for local assessment of complement levels (C3 and C4) to assist in the 
diagnostic evaluation. Complement level results should be included in the specific event form when 
reporting the AE.

Thereafter, repeat testing (at central laboratory) of ALT, AST, ALP and total bilirubin should be 
done regularly until the abnormalities return to normal or baseline state. Additional clinical 
information such as related symptoms, risk factors and contributing conditions (e.g. viral hepatitis, 
autoimmune hepatitis, alcoholic hepatitis, hepatobiliary or pancreatic disorders) should be gathered 
to seek a possible cause of the observed laboratory test abnormalities.

Introduction including rationale for the protocol amendment
This protocol amendment introduces:
1. Change in allowance for eye examinations and additional data collection on diabetic retinopathy
2. Addition of bicarbonate as a part of the biochemistry laboratory assessment
3. Investigator’s responsibility in ensuring evaluation and management of certain risk factors and 
complications
4. Clarification of the criteria for completion, withdrawal and lost to follow-up
5. Other minor corrections and clarifications
1.1
Additional data collection on diabetic retinopathy
Transient worsening of diabetic retinopathy is a recognised complication in selected patients with 
diabetes after initiation of intensive antidiabetic treatment1,2,3. 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. To further understand this safety signal, additional information will 
be collected and for all diabetic retinopathy events reported during the trial. Furthermore, 
information to the investigators and subjects related to diabetic retinopathy has been added to the 
protocol (see Section 18). 
The timepoint of the Eye examination taken at end of trial (EoT) has been moved for subjects 
completing treatment to ensure the treatment period is completed as for other assessments 
performed at EoT. The Eye examination at the EoT must be performed at visit 13 or within 5 weeks 
thereafter for subjects completing treatment, and at visit 13A or within 5 weeks thereafter and again 
within 5 weeks prior to visit 13 for subjects who have prematurely discontinued trial product. This 
has been clarified as a footnote of the flowchart.

1.2
Addition of bicarbonate as a part of the biochemistry laboratory assessment
 that bicarbonate is added as a routine laboratory test in trials where SGLT2-
inhibitors are used as background medication, because SGLT2-inhibitors have been associated with 
a risk for metabolic acidosis.
1.3
Investigator’s responsibility in ensuring evaluation and management of certain risk 
factors and complications
 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 cardiovascular risk factors and microvascular complications such as diabetic kidney 
disease and diabetic retinopathy.
1.4
Clarification of the criteria for completion, withdrawal and lost to follow-up
The criteria for subject completion, -withdrawal and -lost to follow-up respectively is clarified and 
has 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 the subject can be considered lost to follow up. 
Since 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.
1.5
Other minor adjustments, clarifications and correction of typographical errors
Statistical considerations
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. Explanation on Cox proportional 
hazards model has also been added.

Section 8.1.5
End-of-treatment (visit 13) and Follow-up (visit 14)
Subjects, who stay on trial product throughout the trial, must attend the End-of-treatment visit 
(visit 13) 52 weeks after randomisation (±3 days visit window) and the Follow-up visit (visit 14) 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 13 (see Section 10).
At visit 13 the subject should be reminded about the importance of attending the follow-up visit 
(visit 14). If the subject, nonetheless, does not attend visit 14, the site should make efforts to obtain 
contact with the subject within the visit window. 
A trial completer is defined as a subject who attends, or is in contact with the site, at the subject’s
last scheduled visit. For subjects who complete treatment, the last scheduled visit is visit 14. (For 
subjects who discontinue trial product, see Section 8.1.6).
In case the subject cannot be reached (by clinic visit or phone contact) at the scheduled visit 13, the 
site should consult the contacts provided by the subject (e.g. close relatives), relevant physicians
and medical records to collect health status. If no health status can be collected, the subject should 
be considered lost to follow-up and this should be specified in the end-of-trial form. 
2.5
Section 8.1.6
Premature discontinuation of trial product and follow-up (visits 13A 
and 14A)
…
Subjects should continue with the originally scheduled site contacts after visit 14A and up to and 
including visit 13. If necessary, in order to retain the subject in the trial, site visits can be replaced 
by phone contacts after visit 14A. However, if a subject is unable or unwilling to attend all 
subsequent visit(s), the investigator should at least aim to have the subject attend the scheduled 
visit 9 (week 26) and visit 13 (week 52) as these visits should be performed for all subjects, if at all 
possible (except subjects who withdraw informed consent, see Section 8.1.7).
Subjects, who only agree to attend or provide health status at the planned visit 13, should not be 
considered withdrawn from the trial. In case the subject cannot be reached (by clinic visit or phone 
contact) at the scheduled visit 13, the site should consult the contacts provided by the subject (e.g. 
close relatives), relevant physicians, medical records to collect health status. If no health status can

be collected, the subject should be considered lost to follow-up and this should be specified in the 
end-of-trial form. 
A subject who prematurely discontinued trial product is still considered a trial completer if the 
subject attends or is in contact with the site, at the subject’s last scheduled visit. For subjects who 
prematurely discontinue trial product, the last scheduled visit is visit 13 (or visit 14A if it is 
scheduled after visit 13). The site should in due time prepare for establishing contact with the 
subject within the visit window of the scheduled visit 9 and visit 13, respectively if the subject has 
agreed to attend these visits.
In summary, subjects should stay in the trial irrespective of lack of adherence to randomised 
treatment, lack of adherence to visit schedule, missing assessments or trial product discontinuation 
for any reason. Only subjects who decline any further contact with the site in relation to the trial 
should be considered as having withdrawn consent from the trial (for withdrawal procedures, see 
Section 8.1.7).
2.6
Section 8.1.7.1 
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 and medical records 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: visit 14 for subjects who have completed 
treatment, whereas for subjects who have discontinued trial product prematurely the last visit is 
visit 13 (or visit 14A if it is scheduled after visit 13). Only if contact with the subject is not regained 
by the end of the visit window of the last scheduled visit can the subject be considered lost to follow 
up (see Section 6.6).

starts at the date of first dose of trial product. Two slightly different end dates will be needed to
cover all assessments appropriately. For adjudicated events, ECGs, eye examination category and 
AEs including hypoglycaemic episodes, the observation period ends at the first date of any of the 
following:

Efficacy Endpoints (Change from baseline to week 26 in HbA1c)
…
Missing values for each group will be imputed as follows:
!
An analysis of covariance (ANCOVA) with stratification factor as a categorical fixed effect and 
baseline HbA1c measurement as a covariate will be fitted to observed values of the change from 
baseline in HbA1c at week 26.
!
The estimated parameters for location and dispersion will be used to impute 100 1000 values 
for each subject with missing week 26 data based on stratification factor and baseline HbA1c. 
Thus, 100 1000 complete data sets will be generated including observed and imputed values.
For each of the 100 1000 (now complete) imputed data sets, the change from baseline to week 26 
will be analysed using an ANCOVA with treatment and stratification factor as categorical fixed 
effects and baseline HbA1c as a covariate. The results obtained from analysing the datasets will be 
combined using Rubin’s rule49 to draw inference.

Section 17.4.1.1
Efficacy endpoints (Continuous efficacy endpoints)

For evaluation of the primary estimand the analysis will be performed separately for week 26 and 
52. For the analysis at week 52, 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 12 groups of subjects 
instead of the 8 groups as described for the week 26 evaluation above. If less than 5 subjects have 
available data in one of the 16 12 groups, the imputation will be made within the 8 groups specified 
for the primary evaluation.

Risks and precautions with oral semaglutide (Diabetic retinopathy

A transient worsening of diabetic retinopathy is a recognised complication in selected patients with 
diabetes after initiation of intensive antidiabetic treatment51, 52, 53. 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 progression4, 54 even in intensively treated patients who experienced early worsening52. 
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 placebo[ref-2]. 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 trial[ref-3].

Section 18.1.1
Risks and precautions with oral semaglutide (General precautions)
All subjects will be included after a thorough evaluation with regards to in- and exclusion criteria 
defined in order to ensure that subjects are eligible for trial treatment. There are also strict 
glyacemic rescue criteria in place to ensure acceptable glycaemic control during the trial. If rescue 
medication is required, it should be in accordance with ADA/European Association for the Study of 
Diabetes29, 30 (excluding GLP-1 RAs, DPP-4 inhibitors and amylin analogues).
It is the responsibility of the investigator to ensure the best possible care of the subject. This 
includes adequate glycaemic control, appropriate risk factor modification such as optimal 
treatment of hypertension, dyslipidaemia and other cardiovascular risk factors, as well as regular 
monitoring and treatment of diabetic kidney disease and diabetic retinopathy(Diabetes Care 2016

Medication error (concerning trial products):
o
Administration of wrong drug or use of wrong device.
Note: Use of wrong dispensing unit number (DUN) is not considered a medication error
unless it results in administration of wrong drug.
o
Wrong route of administration, such as intramuscular instead of s.c.
o
Administration of an overdose with the intention to cause harm (e.g. suicide attempt),
misuse or abuse of trial product
o
Accidental administration of a higher dose than intended. A higher dose of semaglutide is a
dose of at least one tablet more than the intended dose, and for dulaglutide a higher dose
than 0.75 mg/day; 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.
