Clinical trial NCT05259033
Conditions: Diabetes Mellitus, Type 2
Sponsor: Novo Nordisk A/S
Start date: 2022-04-11; Completion date: 2024-01-16
Enrollment: 683 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

Brief summary:
This study will compare the new medicine IcoSema, which is a combination of insulin icodec and semaglutide, taken once a week, to semaglutide taken once a week in people with type 2 diabetes.

The study will look at how well IcoSema controls blood sugar level in people with type 2 diabetes compared to semaglutide.

Participants will either get IcoSema or semaglutide. Which treatment participants get is decided by chance. IcoSema is a new medicine that doctors cannot prescribe. Doctors can already prescribe semaglutide in many countries.

Participants will get IcoSema or semaglutide, which they must inject once a week with a pen, which has a small needle, in a skin fold in the thigh, upper arm, or stomach.

The study will last for about 1 year and 1 month. Participants will have 18 clinic visits, 34 phone/video calls with the study doctor, and 4 contacts with the site that can either be clinic visits or phone/video calls.

At 11 clinic visits participants will have blood samples taken. At 7 clinic visits participants cannot eat or drink (except for water) for 8 hours before the visit.

Women cannot take part if pregnant, breast-feeding or plan to get pregnant during the study period.

Detailed description:

Arms: arm 1: Participants will get once weekly dose arm 2: Participants will get once weekly dose
Interventions: intervention 1: IcoSema intervention 2: Semaglutide 1 mg
Intervention descriptions: intervention 1: IcoSema once weekly subcutaneously (s.c., under the skin) using a needle and a pen.

For about 1 year and 1 month. intervention 2: Semaglutide once weekly subcutaneously (s.c., under the skin). Dose titrated to 1mg over 8 weeks (0.25 mg for 4 weeks, 0.5 mg for 4 weeks). For about 1 year and 1 month.

Protocol version 8.0 (23-Mar-2023) 
This amendment is considered to be non-substantial based on the criteria set forth in Article 10(a) of 
Directive 2001/20/EC of the European Parliament and the Council of the European Union,1 because 
it neither significantly impacts the safety nor physical/mental integrity of participants nor the 
scientific value of the study. 
Overall rationale for preparing protocol, version 8.0: 
The protocol has been amended to correct below errors detected, in addition to further changes 
shown below:  
Section # and name Description of change 
Brief rationale 
Section 2 
Introduction 
Detailed information about the insulin icodec 
molecule has been deleted. 
Alignment with phase 3b protocol. The 
information is not relevant for trial conduct 
Section 2.3 Benefit-
rsik assessment 
Text crossed out was deleted as follows:  
The risks of IcoSema presented in this section 
are a combination of important and 
non-important risks for IcoSema and for the 
mono-components insulin icodec and 
semaglutide. All risks for mono-components 
that have not been identified for IcoSema 
directly, are classified as potential risks for 
IcoSema, although these may be classified as 
identified risks for the mono-components.  
New risks from the mono-components are now 
evaluated using clinical data for IcoSema 
Section 2.3.1 Risk 
assessment 
The IcoSema IB is added as reference for 
benefits and risks of insulin icodec and 
semaglutide instead of the IBs of the mono-
components.    
Alignment with updated IBs 
Section 4.3 
Justification for dose 
Text in italics was added, and text crossed out 
was deleted as follows: 
The maximum dose and the ratio of IcoSema 
is based on the clinical findings [reference to 
IcoSema IB] from the mono-components 
insulin icodec4 and semaglutide s.c.6 
Alignment with updated IBs

eCRF correctly collects injection site area 
collected in both arms, while protocol 
erroneously only described it for IcoSema. 
Injection site area in both arms is required for 
originally planned population PK analysis to 
assess a potential differential effect of injection 
region between IcoSema and the mono-
component 
Section 8.2.4. Eye 
examination 
Text in italics was added, and text crossed out 
was deleted as follows: For participants who 
discontinue randomised treatment, eye 
examination can be performed up to 2 weeks 
after the visit at week 52 visit 54A.  
Clarification of visit number to 54A 
Appendix 2: Clinical 
laboratory tests 
Text and footnotes in italics were added to 
table 10.2: 
Hypersensitivity data will not be shared with 
investigators until after CSR finalisation. 
c Samples collected from Chinese participants 
will be analysed by a central lab in China. 
Samples collected from participants in the 
rest of the world will be analysed by Novo 
Nordisk Måløv, Denmark  
d Samples will be analysed by Novo Nordisk 
Måløv, Denmark for all countries except 
China, where these tests will not be done (see 
Appendix 11, Section 10.11. 
e Samples collected from Chinese participants 
will be analysed in a special lab in China. 
Samples collected from participants in the 
rest of the world will be analysed by a special 
lab designated by Novo Nordisk. 
To clarify which hypersensitivity tests will be 
performed by which laboratories

Added text in italics:  
The following hypersensitivity analytes are 
not possible to be tested in China, see 
Appendix 2 (Section 10.2), and will not be 
included in the hypersensitivity case 
assessment: 
 
Anti-human insulin IgE 
 
Anti-insulin icodec IgE 
 
Anti-semaglutide IgE 
The following hypersensitivity analytes will 
be tested by the Central lab in China: 
 
Tryptase 
 
Total IgE antibodies 
The following hypersensitivity analytes will 
be tested by special lab in China: 
 
Anti-insulin icodec binding antibodies 
 
Anti-semaglutide binding antibodies 
To clearly reflect which hypersensitivity tests 
will be conducted in China due to local 
unavailability of some test and the impossibility 
of exporting samples outside China

1.1 
Synopsis 
This is an interventional, multi-national, multi-centre, randomised, 52-week, open label, parallel 
group, treat-to-target/dose escalation, confirmatory study with two treatment arms.  
Rationale 
This study is designed to investigate the efficacy and safety of once weekly IcoSema, which is a 
combination product of insulin icodec and semaglutide. IcoSema will be compared to once weekly 
1 mg semaglutide s.c., both treatment arms with or without oral anti-diabetic drugs, in participants 
with type 2 diabetes inadequately controlled with a GLP-1 receptor agonist. The purpose is to show 
that there is an added benefit of the combination product compared to the once weekly semaglutide 
mono-component according to regulatory guidelines on clinical development of fixed combination 
products. 
Overall, the results of the present study will be important for evaluating the efficacy and safety of 
IcoSema in GLP-1 receptor agonist experienced participants with type 2 diabetes when 
intensification is needed. Furthermore, once weekly IcoSema is developed to provide a simple 
treatment regimen. 
Objectives, endpoints and estimand 
Primary objective 
To confirm superiority of once weekly IcoSema compared with once weekly semaglutide, both 
treatment arms with or without oral anti-diabetic drugs, in terms of glycaemic control measured by 
change in HbA1c from baseline after 52 weeks in participants with type 2 diabetes inadequately 
controlled with a GLP-1 receptor agonist.

 
Diabetes mellitus is a metabolic disorder characterised by the presence of hyperglycaemia due to 
defective insulin secretion, insulin action or both. Chronic hyperglycaemia of diabetes mellitus is 
associated with significant long-term complications, particularly tissues damage and dysfunction or 
organ failure - especially the kidney, eye, and nerves.2 Diabetes is generally classified according to 
aetiological factors, where type 1 diabetes and type 2 diabetes (T2D) constitutes the vast majority of 
cases. In the Internati76)41)*-<-;-,-:)<176J;1)*-<-;<4);
	<0--;<15)<-,?7:4,?1,-
diabetes prevalence was 463 million, with a prediction that by 2045, the number of people with 
diabetes will have increased to 700 million.3 
T2D is a progressive disease, and the need for treatment intensification over time can be covered in 
a simple setting by a titratable fixed ratio combination product as IcoSema. IcoSema is a 
combination product of insulin icodec and the glucagon-like peptide 1 (GLP-1) receptor agonist 
semaglutide, which is developed to provide an effective and convenient, once weekly treatment 
regimen for people with T2D.  
Insulin icodec is a novel long-acting insulin analogue which is under development (global phase 3a 
programme initiated during the fourth quarter of 2020) to safely cover the basal insulin 
requirements for a full week with a single subcutaneous (s.c.) injection. Insulin icodec has a 
terminal half-life of approximately 196 hours. Insulin icodec is a recombinant protein produced 
using yeast.  
Semaglutide is a GLP-1 receptor agonist with a half-life of 149 to 164 hours, suitable for once 
weekly s.c. administration.4 The long half-life was obtained by applying the fatty acid acylation 
technology that provides specific high-affinity albumin binding. Furthermore, semaglutide has full 
stability against DPP-4 degradation. Semaglutide exhibits GLP-1 receptor mediated effects, leading 
to lowering of glucose and decreased appetite through physiologically relevant mechanisms. As a 
result, semaglutide provides strong glycaemic control and weight loss. In addition, the 
cardiovascular safety of semaglutide has been confirmed. The mechanism of action of semaglutide 
was characterized in extensive non-clinical and clinical studies.5, 6 Semaglutide (Ozempic®) is 
currently approved in more than 60 countries for the treatment of T2D. In addition, semaglutide is 
approved for use in combination with insulin.5 
IcoSema is expected to provide an effect on HbA1c reduction through actions on both fasting and 
prandial glycaemic control. IcoSema is also expected to reduce the risk of hypoglycaemic episodes 
and to provide weight loss compared to basal insulin and basal-bolus insulin treatment, and to show 
a comparable or better gastrointestinal adverse event (AE) profile as compared to semaglutide. 
2.1 
Study rationale 
The present study is a 52-week, parallel study, with two treatment arms designed to investigate the 
efficacy and safety of once weekly IcoSema in comparison to once weekly 1 mg semaglutide s.c. 
(referred to as semaglutide in this document), both treatment arms with or without oral anti-diabetic 
drugs (OADs), in participants with T2D inadequately controlled with a GLP-1 receptor agonist. The 
purpose is to show that there is an added benefit of the combination product compared to the once 
weekly semaglutide mono-component according to regulatory guidelines on clinical development of 
fixed combination products.7

Overall, the results of the present study will be important for evaluating the efficacy and safety of 
IcoSema in GLP-1 receptor agonist experienced participants with T2D when intensification is 
needed. Furthermore, once weekly IcoSema is developed to provide a simple treatment regimen.  
2.2 
Background 
Diabetes mellitus  
T2D is characterised by insulin resistance, impaired insulin secretion, increased hepatic glucose 
output due to glucagon dysregulation resulting in chronic hyperglycaemia.8 The pathogenesis is not 
fully understood but seems to be heterogeneous, involving environmental, lifestyle, and genetic 
factors leading to chronic hyperglycaemia caused by peripheral tissue insulin resistance, impaired 
insulin secretion due to abnormal beta-cell function and abnormal glucose metabolism in the liver.9 
Treatment of type 2 diabetes mellitus  
The current treatment cascade recommended by the American Diabetes Association and the 
European Association for the Study of Diabetes follows a stepwise approach comprising lifestyle 
changes in combination with pharmacological intervention.10 Metformin is recommended as initial 
therapy, followed by combination therapy with other OADs, GLP-1 receptor agonists and insulin as 
the disease progresses.10 
Despite the development of new treatments, a substantial proportion of people with T2D fail to 
achieve the recommended glycaemic targets. This clinical inertia prolongs the duration of people;J
hyperglycaemia, which consequently puts them at an increased risk of diabetes-associated 
complications and reduced life expectancy. Specifically, there is an unmet medical need for 
products with the potential to improve clinical outcomes through reduced treatment burden, i.e. 
fewer injections, and increased treatment adherence and persistence11 compared to other treatment 
regimens requiring daily or several weekly injections. 
For people with advanced T2D in need of improved fasting and prandial glycaemic control, 
combined treatment with a GLP-1 receptor agonist and a basal insulin can provide improved 
glycaemic outcomes.12 Experiences with fixed ratio combination products e.g. insulin 
degludec/liraglutide (Xultophy®) has shown improved treatment effect whilst reducing the side 
effects compared to the mono-components.13 However, market research has shown that people with 
diabetes would prefer fewer injections14 and increased flexibility15 than currently provided by once 
daily treatment. 
IcoSema  
IcoSema is a once weekly injectable fixed ratio combination product comprising the novel insulin 
icodec and the GLP-1 receptor agonist semaglutide and is developed for late stage treatment 
intensification for people with advanced T2D. The development of IcoSema is based on learnings 
from other fixed ratio combination products e.g. insulin degludec/liraglutide (Xultophy®), showing 
that combination products benefit from the complementary actions of both mono-components on 
glycaemic control. Hence, IcoSema benefits from both insulin icodec and the potent GLP-1 receptor 
agonist semaglutide. IcoSema has been investigated in a clinical pharmacology study 
(NN1535-4359) in participants with T2D. Data from NN1535-4359 has contributed to development 
of the IcoSema titration guidelines included in the phase 3a development programme. A

semaglutide 0.5 and 1.0 mg demonstrated a safety profile in line with the GLP-1 receptor agonist 
class, and clinically relevant and superior glycaemic control and weight loss versus placebo and 
active comparators, both as monotherapy, in drug-naïve people with T2D, and in combination with 
other anti-hyperglycaemic agents, including basal insulin, in people with T2D with inadequate

IcoSema 
Identified risk  
Gastrointestinal AEs (Nausea, 
vomiting and diarrhoea) 
Gastrointestinal AEs is a class risk 
for all GLP-1 receptor agonist 
products. The precise mechanism 
remains unclear but involves a 
GLP-1 receptor-mediated activation 
and it is therefore considered a class 
risk for all GLP-1 receptor agonist 
products. In general, these reactions 
are mild or moderate in severity, of 
short duration, and dose dependent.   
In the phase 1 single dose study 
!!	N57:-participants 
experienced gastrointestinal AEs, 
predominantly nausea and vomiting, 
following administration of IcoSema 
compared to the mono-components. 
This was likely due to the relatively 
higher maximum concentration of 
semaglutide following IcoSema 
administration of 175 units / 0.5 mg 
compared to separate dose 
administration of 0.5 mg 
semaglutide. 
Gastrointestinal AEs have also been 
observed in non-clinical studies as 
well as the clinical studies with 
semaglutide. The most frequently 
reported AEs across the semaglutide 
clinical programmes were 
gastrointestinal AEs (e.g., nausea, 
vomiting and diarrhoea).   
 
To mitigate the risk of 
gastrointestinal AEs, once weekly 
IcoSema will be initiated at a low 
starting dose of 40 dose steps 
(equivalent to 40 units of insulin 
icodec and 0.114 mg of semaglutide, 
i.e. half the semaglutide starting dose 
of 0.25 mg) and titrated with 
±10 dose steps (equivalent to 
10 units of insulin icodec and 
0.029 mg of semaglutide) to a 
maximum dose of 350 dose steps 
(equivalent to 350 units of insulin 
icodec and 1 mg of semaglutide). 
Participants who experience 
vomiting and/or diarrhoea will be 
instructed to maintain adequate fluid 
intake to compensate for the volume 
depletion. 
Identified risk  
Hypoglycaemia 
 
Hypoglycaemia is an anticipated 
undesirable effect related to the 
pharmacological mechanism of 
insulin. 
In the phase 1 single dose study 
!!	N0A87/4A+)-51+
episodes were reported in ~33% 
participants in the IcoSema arm and 
32% of the participants in the insulin 
icodec arm. No severe 
hypoglycaemic episodes were 
reported. Most hypoglycaemic 
episodes were asymptomatic.  
Hypoglycaemia has been observed 
in clinical studies with insulin 
icodec. There is a low risk of 
hypoglycaemic episodes when 
semaglutide is used as 
mono-therapy. 
Frequent blood glucose 
measurements are encouraged 
throughout drug exposure by means 
of a blood glucose (BG) meter. The 
participant will receive written 
information describing 
hypoglycaemic symptoms and how 
to manage low blood glucose levels. 
Prevention or worsening of 
hypoglycaemia will be sought by 
early detection and administration of 
carbohydrates and medical treatment, 
if needed.  
When adjusting IcoSema dose, 
recommended titration schemes 
should be followed.

One non-serious type-1 
drug-induced hypersensitivity 
reaction was reported in the IcoSema 
phase 1 single dose study NN1535-
4359. 
No systemic hypersensitivity 
reactions have been observed in 
clinical studies with insulin icodec.  
Hypersensitivity is an adverse 
reaction identified in phase 3a 
studies for semaglutide in 
participants with T2D. 
randomised treatment will not be 
enrolled in this study.  
Participants and investigators will be 
instructed about the signs and 
symptoms of allergic reactions and 
instructed to contact the site 
immediately in case of signs of 
hypersensitivity. 
 
 
Potential risk:  
Serious allergic reactions 
As with all protein-based drugs, 
treatment with IcoSema may evoke 
allergic reactions, including severe 
systemic hypersensitivity reactions 
and angioedema.  
No serious allergic reactions have 
been observed with IcoSema in the 
phase 1 single dose study 
NN1535-4359. 
No systemic hypersensitivity 
reactions have been observed in 
studies with insulin icodec.  
Events of allergic reactions 
(generally mild and non-serious) 
have been reported in participants 
with T2D treated with semaglutide. 
Few events of anaphylactic reaction 
were reported; however, none of 
these events were related to the 
treatment with semaglutide. Events 
of angioedema were also reported 
from post marketing sources. 
As a precaution, participants with 
suspected hypersensitivity to 
randomised treatment will not be 
enrolled in this study.  
Participants and investigators will be 
instructed about the signs and 
symptoms of allergic reactions and 
instructed to contact the site 
immediately in case of signs of 
hypersensitivity. 
 
 
Potential risk:  
Medication error due to potential 
mix-up  
Despite the open-label study design, 
medication error is still an applicable 
risk for participants treated with 
multiple insulins. Medication errors 
can have clinical consequences such 
as hypoglycaemia or 
hyperglycaemia.  
No information is available from 
completed clinical studies with 
IcoSema. Very few medication 
errors have been observed in the 
completed clinical studies with 
insulin icodec, none associated with 
AEs. 
Participants will be instructed to 
visually verify the dialled units on 
the dose counter of the pen. In 
studies involving different pens, 
participants must be instructed to 
always check the pen label before 
each injection to avoid potential 
mix-ups. 
 
Potential risk:  
Injection site reactions 
Injection site reactions may occur 
with all injectable peptide-based 
treatments.  
In the phase 1 single dose study 
NN1535-4359 with IcoSema, one 
event of injection site haematoma 
was reported after administration of 
the mono-component semaglutide. 
Participants will be instructed to 
monitor for signs and symptoms of 
injection site reactions. Participants 
should be instructed to contact the 
site immediately in case of signs of 
worsening of injection site reactions 
for further action.

Risk of clinical significance 
Summary of data/rationale for 
risk 
Mitigation strategy 
Injection site reactions were 
observed in participants with T2D 
treated with insulin icodec.  
In the studies with semaglutide s.c. 
for T2D, injection site reactions 
were reported by a low 
(approximately 1%) proportion of 
participants with semaglutide and 
were not recurrent in those 
individuals.  
Participants will be instructed on the 
most appropriate injection 
techniques. Recommendations on 
rotation of the site of injection are 
included in Table 6-1. 
Potential risk 
Diabetic retinopathy complications  
 
The risk of diabetic retinopathy 
complications has been observed in 
T2D treated with semaglutide in 
clinical studies.  
In a 2-year clinical study with. 
semaglutide s.c (NN9535-3744) 
involving 3,297 participants with 
T2D, high cardio vascular risk, long 
duration of diabetes and poorly 
controlled blood glucose, 
EAC-confirmed events of diabetic 
retinopathy complications occurred 
in more participants treated with 
semaglutide s.c (3.0%) compared to 
placebo (1.8%). The absolute risk 
increase for diabetic retinopathy 
complications was larger among 
participants with a history of diabetic 
retinopathy at baseline. In the 
participants who did not have a 
documented history of diabetic 
retinopathy the number of events 
was similar for semaglutide s.c and 
placebo. In the other clinical studies 
up to 1 year involving 4,807 
participants with T2D, AEs related 
to diabetic retinopathy were reported 
in similar proportions of participants 
treated with semaglutide s.c (1.7%) 
and comparators (2.0%). 
Rapid improvement in glucose 
control has been associated with a 
temporary worsening of diabetic 
retinopathy, but other mechanisms 
cannot be excluded. Long-term 
glycaemic control decreases the risk 
of diabetic retinopathy. These 
participants should be monitored 
closely and treated according to 
clinical guidelines.  
Participants will have an eye 
examination performed at baseline 
and at week 52. Diagnostic artificial 
intelligence algorithms may possibly 
be used as screening tool. If 
diagnostic artificial intelligence 
algorithms are used and in case of 
changes indicated by the algorithm, 
an additional eye examination must 
be performed, see section 8.2.4. 
Uncontrolled and potentially 
unstable diabetic retinopathy or 
maculopathy is an exclusion 
criterion in this study.  
Potential risk:  
Acute pancreatitis  
Acute pancreatitis has been observed 
with the use of GLP-1 receptor 
agonists. In the completed phase 3 
studies with semaglutide s.c. and 
oral semaglutide, both the event rate 
and the proportion of participants 
experiencing confirmed pancreatitis 
were similar with semaglutide and 
comparator. Few events were 
confirmed; the events occurred 
throughout the study periods and the 
overall rates were similar to the rates 
reported in background populations. 
Participants should be informed of 
the characteristic symptoms of acute 
pancreatitis and if pancreatitis is 
suspected, IcoSema or semaglutide 
should be discontinued. If 
confirmed, IcoSema or semaglutide 
should not be restarted.

Risk of clinical significance 
Summary of data/rationale for 
risk 
Mitigation strategy 
Potential risk:  
Neoplasms (malignant and non-
malignant) 
Participants with T2D, as well as 
participants with overweight or 
obesity, have an increased risk of 
certain types of cancer. There is no 
evidence from clinical studies that 
GLP-1-based therapies increase the 
risk of neoplasms. However, in the 
semaglutide s.c. as well as oral 
semaglutide phase 3a studies, the 
proportion of participants with 
neoplasms (malignant and non-
malignant) were slightly higher with 
semaglutide than with comparator. 
The number of participants exposed 
to semaglutide s.c. or oral 
semaglutide for a longer period is 
considered insufficient for a 
thorough assessment of the risk of 
neoplasms. 
 
Participants with presence or history 
of malignant neoplasm within 
5 years prior to the day of screening 
will not be enrolled in this study. 
Basal and squamous cell skin cancer 
and any carcinoma in-situ is allowed. 
 
 
Potential risk:  
Pancreatic cancer 
Participants with T2D have an 
increased risk of certain types of 
cancer such as pancreatic cancer. 
There is currently no support from 
non-clinical studies, clinical studies 
or post-marketing data that GLP-1 
based therapies increase the risk of 
pancreatic cancer. However, 
pancreatic cancer has been classified 
as a potential class risk for all 
marketed GLP-1 receptor agonists 
by regulatory agencies. There is no 
indication of an increased relative 
risk in the semaglutide treatment 
groups vs. comparator, including 
placebo. The rates of EAC-
confirmed events of pancreatic 
cancer were consistently low across 
studies. 
Participants with history of 
malignant neoplasm within 5 years 
prior to the day of screening will not 
be enrolled in this study. 
 
Potential risk:  
Medullary thyroid cancer 
Thyroid C-cell tumours were seen in 
mouse and rat carcinogenicity 
studies after daily exposure to 
semaglutide for 2 years. The rodent 
C-cell tumours are caused by a non-
genotoxic, specific GLP-1 receptor 
mediated mechanism to which 
rodents are particularly sensitive. No 
C-cell tumours were observed in 
monkeys after 52 weeks exposure up 
to 52-fold above the clinical plasma 
exposure at 14 mg/day. The GLP-1 
receptor is not expressed in the 
normal human thyroid, and therefore 
the clinical relevance of the findings 
is considered to be low. 
Exclusion criteria related to personal 
or first-degree relative(s) history of 
multiple endocrine neoplasia type 2 
or medullary thyroid carcinoma.

Study procedures 
Risk of COVID-19 infection in  
relation to participation in study  
Participants may be exposed to the 
risk of COVID-19 transmission and 
infection in relation to site visits if 
an outbreak is ongoing in the given 
country.  
 
 
The risk of COVID-19 transmission 
in relation to site visits is overall 
considered to be low, however this 
may vary between geographical 
areas. 
To minimize the risk as much as 
possible, the following measures 
have been taken: 
 Cautious participant 
recruitment planning ensures 
controlled participant 
enrolment in countries where 
the COVID-19 pandemic is 
evaluated to be sufficiently 
under control, and at sites 
where health care resources are 
evaluated to be adequate. 
 Study procedures including the 
number and frequency of study 
procedures and assessments 
have been critically evaluated 
to limit the number of on-site 
visits to the extent possible. 
Remote visits can be performed 
either by phone or by video call 
depending on the preference of 
the participant and the 
investigator.  
 Guidance is provided to site 
staff to request that on-site 
visits are planned to be as short 
as possible. Physical contact 
between participants and site 
staff will be limited to the 
extent possible, and protective 
measures will be implemented 
(describe e.g. use of masks, 
sanitizers, no 
aerosol-generating procedures 
etc.). 
 Please refer to Appendix 10 
(Section 10.10) which lists the 
additional actions to be taken 
in case a site or country are 
locked down and it is not 
possible for participants to visit 
the site. 
Other 
Device medication error  
If the pen-injector is damaged or 
used differently than described in the 
directions for use, a risk of overdose 
or underdose of randomised 
treatment exists. This may cause 
hypoglycaemia due to overdose or 
hyperglycaemia due to underdose. 
Training in injections and use of 
devices and guidance materials for 
investigator, site staff and 
participants will be provided.

Studies in animals have shown 
reproductive toxicity in studies with 
semaglutide. There are limited data 
from the use of semaglutide in 
pregnant women. 
The randomised treatment should not 
be used during pregnancy. Women 
of childbearing potential are required 
to use highly effective contraceptive 
methods when participating in the 
study, see Appendix 4 (Section 10.4, 
Table 10-3). If a participant wishes 
to become pregnant, or pregnancy 
occurs, the randomised treatment 
should be discontinued, please refer 
to Section 8.3.5 for further 
guidance). The effect of IcoSema on 
fertility in humans is unknown.  
 
Risk assessment has been conducted for the PDS290 pen-injector for IcoSema in accordance with 
ISO 14971:2019 when using the PDS290 pen-injector in people with T2D. All identified risks (i.e. 
injection site reactions, see Table 2-1) associated with using the PDS290 pen-injector for IcoSema 
according to the clinical procedures specified in this protocol have been reduced as far as possible 
and are acceptable, taking into account the current state of the art. The use of the PDS290 
pen-injector for IcoSema, in this study is therefore considered to be of non-significant risk. 
2.3.2 
Benefit assessment 
Based on experience from the mono-components and on the learnings from insulin 
degludec/liraglutide as described in the introduction, we expect at positive benefit of the 
combination product IcoSema. This benefit assessment section is based on clinical data available 
for the mono-components insulin icodec and semaglutide in the T2D population. 
Insulin icodec is currently in development and has been shown to have a long and stable 
pharmacokinetic and pharmacodynamic profile supporting a once weekly treatment. Market 
research has shown that people with diabetes mellitus would prefer fewer injections and greater 
flexibility than those provided by the current once daily treatment regimen.14 Therefore, the 
compliance and quality of life are expected to increase by introducing a once weekly basal insulin 
treatment.

Clinical data on once weekly semaglutide have demonstrated superior glycaemic control, superior 
reductions in body weight versus placebo and active comparators, and reduced cardiovascular risk 
compared to placebo in participants with T2D. Further, once weekly dosing offers flexibility and 
fewer injections as opposed to current therapy.  
Based on these data, the combination of semaglutide and insulin icodec in a once weekly fixed ratio 
combination product is expected to provide superior efficacy on HbA1c lowering compared to the 
mono-components.  
IcoSema is also expected to show a comparable or better gastrointestinal AE profile as compared to 
semaglutide. 
For all participants, the anticipated benefits include improved glycaemic control. To ensure all 
participants receive adequate treatment, investigators are encouraged to optimise glycaemic control 
every week throughout the study in accordance with the titration guidelines, see Appendix 8 
(Section 10.8). Participants will receive intense medical care by means of weekly contact with the 
sites.  
2.3.3 
Overall benefit-risk conclusion 
No new significant safety information that changes the current benefit-risk profile of IcoSema 
emerged from the completed phase 1 single dose IcoSema study NN1535-4359 or safety profile 
generated from clinical and non-clinical development programme for the mono-components. 
Necessary precautions have been implemented in the design and planned conduct of the study in 
order to minimise the risks and inconveniences of participation in the study. 
IcoSema is expected to provide an effect on HbA1c reduction through actions on both fasting and 
prandial glycaemic control. IcoSema is also expected to reduce the risk of hypoglycaemic episodes 
and to provide weight loss compared to basal insulin and basal-bolus insulin treatment, and to show 
a comparable or better gastrointestinal AE profile as compared to semaglutide. 
Considering the measures taken to minimise risk to participants, the potential risks identified in 
association with IcoSema are justified by the anticipated benefits that may be afforded to people 
with T2D. 
More detailed information about the known and expected benefits and risks of IcoSema can be 
found in the current i6>-;<1/)<7:J;brochure16 or any updates hereof.

Primary estimand 
The primary clinical question of interest 
What is the treatment effect between once weekly IcoSema and once weekly semaglutide in change 
in HbA1c from baseline to week 52 in participants with T2D inadequately controlled with a GLP-1 
receptor agonist regardless of discontinuation of randomised treatment for any reason and 
regardless of initiation of non-randomised insulin treatment or additional anti-diabetic treatments 
for more than 2 weeks?  
The primary estimand is described by the following 5 attributes: 
 Treatment condition: The effect of randomised treatment (titration of once weekly IcoSema 
versus fixed dose escalation of once weekly semaglutide 1 mg) with or without OAD(s),  
regardless of initiation of non-randomised insulin treatment or additional anti-diabetic 
treatments for more than 2 weeks and adherence to randomised treatment 
 Population: T2D inadequately controlled with a GLP-1 receptor agonist 
 Endpoint: Change in HbA1c from baseline to week 52 
 Remaining ICEs: None. The two intercurrent events are captured under treatment condition and 
handled as follows:  
o Initiation of non-randomised insulin treatment or additional anti-diabetic treatments 
for more than 2 weeks by the treatment policy strategy 
o Discontinuation of randomised treatment for any reason by the treatment policy 
strategy 
 Population-level summary: Difference in mean changes from baseline 
The rationale for the primary estimand is that this estimand captures both the efficacy and safety of 
the randomised treatment with and without additional anti-diabetic/glucose-lowering medication 
and thus aim at reflecting clinical practice.

Overall design
This is an interventional, multi-national, multi-centre, randomised, 52-week, open label, parallel 
group, treat-to-target/dose escalation, confirmatory study with two treatment arms. The study 
investigates the efficacy and safety of treatment with once weekly IcoSema compared to once 
weekly semaglutide, both treatment arms with or without OADs, in participants with T2D 
inadequately controlled with a GLP-1 receptor agonist. 
The study duration is approximately 59 weeks and consists of:

an up to 2 weeks screening period

a 52-week treatment period

a 5-week follow-up period
The study includes a screening visit (V1) to assess participantJ;-41/1*141<A.<-:;+:--616/)44
eligible participants will be randomised (1:1) at visit 2 (V2). The overall study design and visit 
schedule are outlined in Figure 4-1 and the study flowchart (Section 1.2), respectively.
Figure 4-1
Study design
680 participants will be randomised (1:1) to receive once weekly IcoSema or once weekly 
semaglutide. With the exception of oral GLP-1 receptor agonists, sulfonylureas, glinides and DPP-4 
inhibitors that must be discontinued at randomisation (V2), the dose and dosing frequency of any 
pre-study OADs should not be changed during the study, unless due to safety concerns. 
During the study, participants will measure daily self-measured plasma glucose (SMPG). The 
SMPG measurements will be evaluated by the investigator at the weekly contact either as site visits, 
by phone or video call. At the weekly contacts, the dosing will be adjusted in accordance with the

The treatment period is followed by a 5-week follow-up period to ensure safety data collection. 
During the follow-up period, two follow-up visits (V55 and V56) will be performed, 2 and 5 weeks 
after the visit at week 52 (V54), respectively. Hence, the last follow-up visit (V56) will take place 
6 weeks after the last dose of once weekly IcoSema or once weekly semaglutide. The last follow-up 
visit (V56) is scheduled to allow for appropriate wash-out of randomised treatment, following at 
least 5 half-lives of once weekly IcoSema or once weekly semaglutide. 
In case of persistent and unacceptable hyperglycaemia as judged by the investigator based on the 
daily SMPGs, and in accordance with local standard of care, treatment with non-randomised insulin 
(basal or bolus) limited to up to 14 consecutive days can be considered to be added to the 
randomised treatment at the discretion of the investigator to safeguard the participants. Initiation of 
new anti-diabetic medication and any changes hereto must be recorded on the concomitant 
medication form in the eCRF. 
Event adjudication will be performed for acute coronary syndrome events (acute myocardial 
infarction and unstable angina pectoris requiring hospitalisation), cerebrovascular events (stroke 
and transient ischemic attack), heart failure (requiring hospitalisation and urgent heart failure visit) 
and all-cause death. All AEs will be collected from visit 2 and recorded from visit 3. 
Overall, the measures taken to ensure participantJs safety, includes weekly contacts with site staff, a 
5-week follow-up period, training of investigators and other site staff, safety surveillance including 
event adjudication and titration surveillance. In addition, in accordance with GCP, it is the 
investigators responsibility to assess participant's safety and at their discretion act accordingly. 
4.2 
Scientific rationale for study design 
The study is designed in alignment with the estimand (Section 3) to investigate the efficacy and 
safety of once weekly IcoSema compared to once weekly semaglutide during 52 weeks. 
In order to confirm the superiority of the fixed ratio combination of IcoSema to its GLP-1 receptor 
agonist mono-component, once weekly semaglutide is the comparator. The treatment arms will be 
open label in order to avoid the risk of pen-mix-up in a double-blind, double dummy study. 
Furthermore, the open label design has also been chosen due to the different titration/escalation of 
the two different regimens; treat-to-target for the IcoSema arm with a max allowed weekly dose of 
IcoSema of 350 dose steps (equivalent to 350 units insulin icodec and 1 mg semaglutide), and fixed 
dose/dose escalation treatment of semaglutide with a maximal recommended weekly dose of 1 mg, 
see also Appendix 8 (Section 10.8). Blinding of the study would increase the treatment complexity 
and hence increase the burden on the participants. 
The treatment duration of 52 weeks is evaluated to be adequate for assessing efficacy on glycaemic 
control as well as safety. This duration will also ensure sufficient time to reach the maintenance 
dose of IcoSema for the broad study population and allow adequate time in maintenance phase. The 
treat-to-target approach has been chosen to ensure optimal titration of the IcoSema arm based on 
SMPG values with the aim of improving HbA1c in the treatment period. The dose escalation of the 
fixed dose treatment of semaglutide to obtain a maximal recommended weekly dose of 1 mg is in 
accordance with the current EMA summary of product characteristics for semaglutide (Ozempic®),5 
the US prescribing information for semaglutide (Ozempic®),6 or any locally approved label.

Participants entering the study will be insulin naïve and inadequately controlled with a daily or 
weekly GLP-1 receptor agonist with or without OADs ensuring a study population representative of 
a broad and advanced T2D population.  
Risk of hypoglycaemia increases when insulin secretagogues like sulfonylureas and glinides are 
used in association with insulin and combination injectable anti diabetic therapy.10, 18 Hence, to 
minimise the risk, sulfonylureas and glinides are discontinued at randomisation (V2). DPP-4 
inhibitors must likewise be discontinued since the combined use of a GLP-1 receptor agonist 
(semaglutide component of IcoSema) and a DPP-4 inhibitor is not currently recommended.19 
To safeguard participants, the inclusion and exclusion criteria defined in this study will limit the 
study population to participants not suffering from advanced underlying diseases other than T2D 
and related diseases. This is to avoid compromising the safety of the participants, and to strengthen 
the conclusions regarding the efficacy and safety of IcoSema. 
For more information on the study population, see the inclusion and exclusion criteria, Sections 5.1 
and 5.2, respectively. 
4.3 
Justification for dose 
The IcoSema pen is developed with one ratio and one titration algorithm for the phase 3a 
programme in order to simplify the treatment regiments for patients and physicians.  
Once weekly IcoSema will be switched from the pre-study daily or weekly GLP-1 receptor 
agonists. IcoSema will be initiated at 40 dose steps (equivalent to 40 units of insulin icodec and 
0.114 mg of semaglutide), and titrated to target according to the principles outlined in the titration 
guideline in Appendix 8 (Section 10.8).  
The starting dose of 40 dose steps (equivalent to 40 units of insulin icodec and 0.114 mg of 
semaglutide) is selected based on pharmacokinetics (PK) findings from the development 
programme of IcoSema. The combination of the starting dose and the titration algorithm of ±10 
dose step increments (equivalent to 10 units of insulin icodec and 0.029 mg of semaglutide) is 
considered to be safe, due to the combined action of the two mono-components on both fasting and 
prandial glycaemic control. Furthermore, the selected starting dose and titration algorithm are 
expected to ensure a comparable or better gastrointestinal adverse event (AE) profile as compared 
to semaglutide s.c.  
The maximum dose of 350 dose steps is equivalent to 350 units insulin icodec and 1 mg 
semaglutide, which is the currently approved maximum dose for semaglutide s.c. in treatment of 
T2D  (as of 21 June 2021).5,6 The maximum dose and the ratio of IcoSema is based on the clinical 
findings16 and learnings from the once daily fixed ratio combination product, insulin 
degludec/liraglutide (Xultophy®).13The ratio is selected with the focus on balancing the benefits 
from semaglutide and the expected durability of treatment with the insulin component. Providing 
350 units of insulin icodec to 1 mg of semaglutide, is expected to meet the clinical needs for the 
majority of the target population, while their safety is also ensured.  
Once weekly semaglutide will be switched from the pre-study daily or weekly GLP-1 receptor 
agonist. Semaglutide will be initiated at a dose of 0.25 mg and follow a fixed dose escalation

regimen. After 4 weeks of treatment with 0.25 mg, the dose should be increased to 0.5 mg once 
weekly. After at least 4 more weeks the dose should be increased to 1 mg once weekly. See the 
titration guideline in Appendix 8 (Section 10.8). 
After randomisation, participants should start once weekly injections of IcoSema or semaglutide on 
the same day as randomisation. Due to the long half-life of the IcoSema and semaglutide, the last 
once weekly injections must be taken 51 weeks after randomisation.

End of study definition 
The end of the study is defined as the date of the last visit of the last participant in the study 
globally. 
A participant is considered to have completed the study if he/she has completed all periods of the 
study including the visit at week 52 (V54) and the last follow-up visit (V56). 
The primary endpoint is evaluated at the visit at week 52 (V54). The primary completion date is 
defined as the date of visit at week 52 (V54) on which the last participant in the clinical study has 
an assessment for the primary endpoint. If the last participant is withdrawn early from the study, the 
primary completion date is considered the date when the second-to-last participant completes the 
visit at week 52 (visit 54).

The investigator or designee must instruct the participant on how to manage and record the in-use 
time of the dispensed products. The in-use time can be found in the Trial Materials Manual. 
 
Destruction of trial products can be performed on an ongoing basis and will be done according to 
local procedures after accountability is finalised by the site and reconciled by the monitor. 
All returned (used or un-used), expired or damaged trial products (for technical complaint samples, 
see Appendix 5 [Section 10.5]) must be stored separately from non-allocated trial products. No 
temperature monitoring is required. 
Non-allocated trial products, including expired or damaged products, must be accounted as unused, 
at the latest at closure of the site. 
Acceptable temperature ranges and conditions for storage and handling of each trial product when 
not in use and when in use are described in the Trial Materials Manual and trial product label. 
Each single pen should be accounted for. 
6.3 
Measures to minimise bias: Randomisation and blinding 
All participants will be screened and centrally randomised using an RTSM and assigned to the next 
available treatment according to the randomisation schedule. Trial product will be allocated by the 
RTSM and dispensed by the investigator at the study visits summarised in the flowchart 
(Section 1.2). 
This is an open-label study; however, the specific trial products for a participant will be assigned 
using an RTSM. The site will access the RTSM before the start of trial product administration for 
each participant. Potential bias will be reduced by central randomisation and adjudication. 
6.4 
Drug treatment compliance 
Throughout the study, the investigator will remind the participants to follow the study procedures 
and requirements to encourage participant compliance.

When participants self-administer trial product at home, compliance with trial product 
administration will be assessed, and the assessment documented in source documents at each visit 
where information is available. If any suspicion of non-compliance arises, the site must enter into a 
dialogue with the participant, re-emphasizing the importance of compliance and uncover barriers to 
compliance. This dialogue must be documented. Compliance will be assessed by cross checking the 
following sources and comparing these to the expected use:  
 Drug accountability information  
 Review of eDiaries including SMPG profiles, dosing and hypoglycaemia reporting 
 Evaluating glycaemic control and adherence to the visit schedule 
6.5 
Dose modification 
IcoSema doses are adjusted according to blood/plasma glucose values as described in Appendix 8 
(Section 10.8)  
6.6 
Continued access to randomised treatment after end of study 
Randomised treatment will not be accessible after end of study. When discontinuing randomised 
treatment, the participant should be transferred to a suitable marketed product at the discretion of 
the investigator, please see the titration guideline in Appendix 8 (Section 10.8). The medication 
should be recorded in the concomitant medication form, as described in Section 6.8.  
6.7 
Treatment of overdose 
Accidental overdose must be reported as a medication error. Intentional overdose must be reported 
as misuse and abuse, please refer to Section 8.3 and Appendix 3 (Section 10.3) for further details. 
In the event of an overdose, the investigator should closely monitor the participant for overdose-
related AEs/serious adverse events (SAEs). 
A specific overdose for IcoSema cannot be defined; however, hypoglycaemia may develop over 
sequential stages if the doses administered are too high relative to the participantJ;:-9=1:-5-6<; 
Mild hypoglycaemia can be treated by oral administration of glucose or sugary products.  
Severe hypoglycaemia where the participant is not able to treat him/herself, can be treated by 
glucagon (0.5 to 1 mg) given intramuscularly or subcutaneously by a trained person, by other drugs 
for the indication of treatment hypoglycaemia in accordance with local guidelines or by glucose 
given intravenously by a medical professional. Glucose must also be given intravenously, if the 
participant does not respond to glucagon within 10-15 minutes. If the participant has been 
unconscious, administration of oral carbohydrates is recommended for the participant upon 
regaining consciousness, in order to prevent a relapse. 
Decisions regarding dose interruptions or modifications will be made by the investigator based on 
the clinical evaluation of the participant and in accordance with local standard of care.

Discontinuation of specific sites or of the study as a whole is detailed in Appendix 1 
(Section 10.1.11). 
7.1 
Discontinuation of study intervention 
Study intervention may be discontinued at any time during the study at the discretion of the 
participant or at the discretion of the investigator for safety, behavioural, compliance or 
administrative reasons. 
7.1.1 
Discontinuation of randomised treatment 
Discontinuation of randomised treatment corresponds to discontinuation of IcoSema or 
semaglutide. 
If a participant discontinues randomised treatment, the participant should as soon as possible attend 
the discontinuation visit (V54A).  
The investigator should change participant status in the healthcare professional (HCP) web portal to 
'follow-up' at the discontinuation visit (V54A) to ensure that the participant should no longer report 
randomised treatment dose. 
The participant should also complete the two follow-up visits (V55 and V56).  
 
Hypoglycaemic episodes will not be collected after the last follow-up visit (V56). 
Efforts must be made to have the participants who discontinue randomised treatment attend the visit 
at week 52 (V54) to collect: 
 Data for primary endpoint (HbA1c). 
 Data for secondary endpoint for body weight. 
AEs, medication related to SAEs, and anti-diabetic medication should be collected and recorded in 
the eCRF until the visit at week 52 (V54). No other concomitant medication than medication related 
to SAEs and anti-diabetic medication will be collected and reported in the eCRF for participants 
who discontinue randomised treatment.  
Please, refer to Section 6.6 for treatment after discontinuation of randomised treatment. 
The site should stay in contact with the participants who discontinue randomised treatment by 
phone, video call and/or site visits to motivate the participants to attend the follow-up visits (V55 
and V56) and the visit at week 52 (V54). Site contacts should be documented in the medical record. 
In case of any uncertainty regarding the scheduling of the visits after discontinuation of randomised 
treatment or questions to said visits, the investigator should consult Novo Nordisk for further 
guidance

Only participants who withdraw consent will be considered as withdrawn from the study. 
Participants must be informed about the continued scientific importance of their data, even if they 
discontinue randomised treatment. 
The randomised treatment must be discontinued, if any of the following applies for the participant: 
1. Safety concern related to randomised treatment or unacceptable intolerability 
2. Pregnancy 
3. Intention of becoming pregnant 
4. Simultaneous use of an approved or non-approved investigational medicinal product in another 
clinical study 
Note:  Simultaneous participation in a study with the primary objective of evaluating an 
approved or non-approved investigational medicinal product for prevention or treatment of 
COVID-19 disease or post-infectious conditions is allowed at the investigatorJ;,1;+:-<176
without discontinuation of randomised treatment if simultaneous participation is allowed by 
local authorities.  
5. Lack of efficacy, defined as fulfilment of ALL criteria (a, b and c) below after week 8 and 
onwards: 
a. Mean of pre-breakfast SMPG values (on the two days before and on the day of visit) 
of 3 consecutive weeks after week 8 are above 15 mmol/L (270 mg/dL), AND  
b. no treatable intercurrent cause for the hyperglycaemia (e.g. non-compliance) has 
been identified.  
c. In such case, the participant must be called for a confirmatory fasting plasma glucose 
(FPG) measurement as soon as possible. A confirmatory FPG must be obtained and 
analysed by the central laboratory. If this FPG exceeds 15 mmol/L (270 mg/dL), 
participant fulfils the lack of efficacy criteria. 
To allow time for up-titration of the randomised treatment and to observe the expected effect of 
randomised treatment on glycaemic parameters, lack of efficacy criteria will be applied on week 8 
and onwards. 
The primary reason for discontinuation of randomised treatment must be specified in the CRF, and 
final trial product accountability must be performed. A discontinuation session must be made in the 
RTSM.  
7.1.2 
Temporary discontinuation of randomised treatment 
The participant should adhere to the randomised treatment to the extent possible, with the exception 
of any AEs such as hospitalisation or safety concerns, at the discretion of the investigator. If a 
participant due to an AE or safety concern temporarily has discontinued randomised treatment, 
she/he is allowed to restart randomised treatment, unless any of the discontinuation criteria 
specified in Section 7.1 applies.

7.2 
Participant withdrawal from the study 
A participant may withdraw consent at any time at his/her own request. 
If a participant withdraws consent prior to randomisation, he/she will not be asked to have any 
follow-up assessments performed. The following data must be collected: Demography, completed

participation ended. The end of study form must be completed. 
If a participant withdraws consent after randomisation, the investigator must ask the participant if 
he/she is willing, as soon as possible, to have assessments performed according to discontinuation 
visit V54A. The investigator should also ask the participant if he/she is willing to attend the two 
follow-up visits V55 and V56 (see Section 7.1 regarding the scheduling of the follow-up visits). See 
the flowchart for data to be collected. 
Final trial product accountability must be performed even if the participant is not able to come to 
the site. A discontinuation session must be made in the RTSM. 
If the participant withdraws consent, Novo Nordisk may retain and continue to use any data 
collected before such a withdrawal of consent for the purpose of the study or scientific research. 
If a participant withdraws from the study, he/she may request destruction of any samples taken and 
not tested, and the investigator must document this in the medical record. 
Although a participant is not obliged to give his/her reason(s) for withdrawing, the investigator

7.2.1 
Replacement of participants 
If a participant discontinues randomised treatment, withdraws consent or is withdrawn from the 
study by the investigator, he/she will not be replaced. 
7.3 
Lost to follow-up 
A participant will be considered lost to follow-up if he/she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the site. 
The following actions must be taken if a participant fails to return to the site for a required visit: 
 The site must attempt to contact the participant and reschedule the missed visit as soon as 
possible and counsel the participant on the importance of maintaining the assigned visit 
schedule and ascertain whether the participant wishes to and/or should continue in the study. 
 Before a participant is deemed lost to follow-up, the investigator or designee must make every 
effort to regain contact with the participant  (where possible, at least three telephone calls and, if 
necessary, a certified letter to the par<1+18)6<J;4);<367?65)1416/),,:-;;7:47+)4-9=1>)4-6<

The following sections describe the assessments and procedures, while their timing is summarised 
in the flowchart (Section 1.2). 
Informed consent must be obtained before any study-related activity, see Appendix 1 
(Section 10.1.3). 
All screening evaluations must be completed and reviewed to confirm that potential participants 
meet all inclusion criteria and none of the exclusion criteria. 
The investigator will maintain a screening log to record details of all participants screened and to 
confirm eligibility or record reason for screen failure, as applicable. 
At screening, participants will be provided with a card stating that they are participating in a study 
and giving contact details of relevant site staff that can be contacted in case of emergency.  
Adherence to the study design requirements, including those specified in the flowchart 
(Section 1.2), is essential and required for study conduct.

the current section. Efforts should be made to limit the bias between the assessments. The suggested 
order of the assessments at randomisation visit (V2) is as follows: 
 Blood sample collection 
 Other assessments to confirm eligibility 
 Randomisation in RTSM 
 The investigator should create a participant profile and record administrative information (e.g. 
subject ID, year of birth and gender) and treatment arm in the HCP web portal  
 Participants should be provided with an eDiary and instructed in how to use it  
 The BG meter should be connected with the eDiary  
 A fasting SMPG should be measured using the BG meter 
 Dispensing and dosing of randomised treatment. 
For information regarding the eDiary and HCP web portal please refer to the site guide.  
Please refer to Section 6.4 for drug treatment compliance. 
All data entered in the eDiary is considered source data. The investigator should review all the data 
for the participants through the HCP web portal, before or during each visit/phone contact.

taken for safety reasons. Please refer to Appendix 2 (Section 10.2) for further details on laboratory 
samples. 
8.1 
Efficacy assessments  
Planned time points for all efficacy assessments are provided in the flowchart (Section 1.2) and in 
appendix 2 (10.2). 
8.1.1 
Self-measured glucose  
Participants will be provided with a blood glucose meter (BG meter) including auxiliaries. The BG 
meters use test strips calibrated to plasma values. Therefore, all measurements performed with 
capillary blood are automatically calibrated to plasma equivalent glucose values, which will be 
shown on the display. 
The BG meter provided by Novo Nordisk should be used for the measurements required in the 
protocol. 
Participants must be instructed in how to transfer the results of the SMPG values daily into the 
eDiary.  
A baseline SMPG value, in fasting condition, should be collected using the BG meter at V2. 
Pre-breakfast daily self-measured plasma glucose  
Participants should be instructed to measure their pre-breakfast SMPG daily from week 0 (V2) to 
last follow-up visit (V56) and to transfer the measured SMPG values into the eDiary.  
Selected titration data (e.g. certain SMPGs and dose data) from the eDiary will be used during the 
study for central titration surveillance, to ensure compliance with the titration guideline in 
Appendix 8 (Section 10.8). All data will be stored by Novo Nordisk, see Appendix 1 (Section 10.1). 
8.1.2 
Clinical efficacy 
All protocol-required laboratory assessments, as defined in Appendix 2 (Section 10.2), must be 
conducted in accordance with the flowchart (Section 1.2) and the laboratory manual. 
8.2 
Safety assessments  
Planned time points for all safety assessments are provided in the flowchart (Section 1.2) and in 
appendix 2 (10.2).  
Medical history is a medical event that the participant experienced prior to the time point from 
which AEs are collected. All relevant medical history as judged by the investigator will be recorded 
in the eCRF.

As part of the medical history, information on the following will be collected: 
 History of diabetes 
 History of cardiovascular disorder and procedure  
 History of (non-alcoholic fatty liver disease) NAFLD 
 COVID-19 vaccines 
A concomitant illness is any illness that is already present at the time point from which AEs are 
collected or found as a result of a screening procedure or other study procedures performed before 
exposure to study intervention under clinical investigation. 
In case of an abnormal and clinically significant finding fulfilling the definition of medical history 
or concomitant illness, the investigator must record the finding on the medical history/concomitant 
illness form. 
8.2.1 
Dose  
The prescribed IcoSema and semaglutide doses will be determined by the investigator in 
accordance with the titration guideline, see Appendix 8 (Section 10.8). 
The investigator must record the first and last date of trial product in the eCRF.  
During the study, starting at randomisation (V2), participants must be instructed to report date, 
actual dose applied and time of once weekly IcoSema or once weekly semaglutide in the eDiary. 
The injection site area of IcoSema and semaglutide must be reported in the eCRF.  
Please refer to Appendix 8 (Section 10.8) for more information. 
8.2.2 
Physical examinations 
A physical examination will include assessments of: 
 Head, ears, eyes, nose, throat, neck 
 Respiratory system 
 Cardiovascular system 
 Gastrointestinal system including mouth 
 Musculoskeletal system 
 Central and Peripheral Nervous System 
 Skin 
Investigators should pay special attention to clinical signs related to previous serious illnesses. 
Abnormal, clinically significant findings at screening should be recorded as concomitant illness in 
the eCRF. At the following visits, any new abnormal, clinically significant findings or clinically 
significant deteriorations after randomisation should be reported as an AE, see Appendix 3 
(Section 10.3).

flowchart (Section 1.2). Waist circumference will be measured and recorded at visits V2, V28, V54 
and V54A (if applicable). 
 Fasting body weight should be measured in kilogram (kg) or pounds (lb) without coat and shoes 
wearing only light clothing. Body weight will be recorded to one decimal.  
 Body weight should be assessed with the same equipment throughout the study, if possible. 
 Height should be measured in centimetres (cm) or inches (in) without shoes. Height will be 
recorded to the nearest whole number. 
 The waist circumference is defined as the minimal abdominal circumference located midway 
between the lower rib margin and the iliac crest and will be measured using a non-stretchable 
measuring tape. The measurement of waist circumference should be performed and recorded in 
the eCRF to the nearest ½ cm or ¼ in using the same measuring tape throughout the study. The 
waist circumference should be measured in a standing position with an empty bladder and 
wearing light clothing with accessible waist. The participant should be standing with arms down 
their side and feet together. The tape should touch the skin but not compress soft tissue. The 
participant should be asked to breathe normally, and the measurement should be taken when the 
subject is breathing out gently. 
From the body weight and height measured at V1, the body mass index (BMI) should be calculated 
to evaluate inclusion criteria no. 8 and recorded in the participantJ;5-,1+)4:-+7:,;. 
8.2.3 
Vital signs 
Pulse rate as well as systolic and diastolic blood pressure will be assessed. 
Blood pressure and pulse rate measurements should be preceded by at least 5 minutes of rest for the 
participant in a quiet setting without distractions (e.g., no use of television, cell phones). 
Blood pressure and pulse rate measurements will be assessed sitting with a completely automated 
device. Manual techniques must be used only if an automated device is not available. 
Blood pressure and pulse rate are collected at screening (V1), randomisation (V2), V12, V20, V28, 
V38, V46, V54, and V54A. 
Blood pressure will consist of 3 systolic and diastolic blood pressure measurements with intervals 
of at least 1-2 minutes. An additional fourth blood pressure measurement must be performed if the 
first two readings on systolic or diastolic blood pressure differ by >10 mmHg. No more than four 
measurements should be performed. 
 
 The last 2 systolic and last 2 diastolic blood pressure measurements should be recorded in the 
CRF. 
 
Pulse rate will be measured in connection to the blood pressure measurements. 
 
 The pulse rate for the last 2 measurements should be recorded in the CRF.

8.2.4 
Eye examination 
Participants with uncontrolled and potentially unstable diabetic retinopathy or maculopathy are not 
eligible as this indicates retinopathy that has recently progressed to a level that requires intervention 
or is approaching intervention but has yet to be brought under control. 
Results of an eye examination performed by an ophthalmologist or another suitably qualified health 
care provider (e.g., optometrist) possibly aided by diagnostic artificial intelligence algorithms 
approved by FDA and/or CE-marked must be available and evaluated by the investigator before 
randomisation to assess eligibility. The eye examination should be performed as a fundus 
photography (e.g., 2-field 60 degree or better, colour or red-free) or by slit-lamp biomicroscopy 
examination (e.g., using a pre-corneal or corneal contact lens examination). Pharmacological pupil-
dilation is a requirement unless using a digital fundus photography camera specified for non-dilated 
examination. If diagnostic artificial intelligence algorithms are used an additional eye examination 
may be necessary if indicated so by the algorithm. 
If the participant had such an eye examination performed within 90 days prior to screening, the 
investigator may base his/her evaluation upon the results of that examination. The examination must 
be repeated before randomisation if the participant has experienced worsening of visual function 
since the last examination. If the applicable eye examination was performed before the participant 
signed the informed consent form, it must be documented that the reason for performing the 
examination was not related to this study. 
It is recommended that high risk T2D patients (individuals with T2D d=:)<1767.E	A-):;)
baseline HbA1c >8% and confirmed diabetic retinopathy at baseline) will have an additional eye 
examination in accordance with local standard of care , i.e. every 6-month performed by an 
ophthalmologist or another suitably qualified health care provider (e.g., optometrist) possibly aided 
by diagnostic artificial intelligence algorithms approved by FDA and/or CE-marked. 
Eye examinations required at the visit at week 52 (V54) can be performed within 2 weeks before 
the visit, if results are available for evaluation at the visit. For participants who discontinue 
randomised treatment, eye examination can be performed up to 2 weeks after the visit V54A. The 
investigator should examine the outcome of each eye examination. Relevant findings before 
randomisation must be recorded as concomitant illness/medical history. While relevant findings 
occurring after randomisation should be reported as an AE, please refer to Section 8.3 and 
Appendix 3 (Section 10.3).  
8.2.5 
Electrocardiograms 
The ECG should be preceded by at least 5 minutes of rest for the participant in a supine/sitting 
position in a quiet setting without distractions (e.g. no use of television, cell phones). 
The ECG must be interpreted, signed and dated by the investigator to verify that the data has been 
reviewed. 
The ECG required at screening can be obtained within two weeks before randomisation (V2) but at 
the latest at randomisation (V2). The results must be interpreted by the investigator before 
randomisation in order to determine the eligibility of the participant.

The ECG required at the visit at week 52 (V54) can be obtained within two weeks before the visit. 
The results must be available for evaluation at the visit. 
Abnormal, clinically significant findings at screening should be recorded as concomitant illness in 
the eCRF. At the following visits, any new abnormal, clinically significant findings or clinically 
significant deteriorations after randomisation should be reported as an AE, see Appendix 3 
(Section 10.3). 
8.2.6 
Clinical safety laboratory assessments 
All protocol-required laboratory assessments, as defined in Appendix 2 (Section 10.2), must be 
conducted in accordance with the protocol flowchart (Section 1.2) and the laboratory manual. 
8.2.7 
Pregnancy testing  
Woman of childbearing potential (WOCBP) should only be included after a negative, highly 
sensitive urine pregnancy test (refer to Appendix 2 (Section 10.2)). 
Pregnancy testing should be performed whenever a menstruation is missed or when pregnancy is 
otherwise suspected. 
Additional pregnancy testing should be performed during the treatment period, if required locally, 
refer to Appendix 11 (Section 10.11). 
8.3 
Adverse events and other safety reporting 
The investigator is responsible for detecting, documenting, recording and following up on events 
that meet the definition of an AE or SAE. 
 
The definition of AEs and SAEs can be found in Appendix 3 (Section 10.3), along with a 
description of AEs requiring additional data collection. The definition and description of events for 
adjudication can be found in Appendix 9 (Section 10.9). 
Some AEs require additional data collection on a specific event form. The relevant event(s) are 
listed below in Table 8-1, together with event(s) for adjudication and other events requiring 
collection of additional information. 
Events for adjudication require completion of an adjudication form, please refer to Appendix 9 
(Section 10.9).

Appendix 9 (Section 10.9) for events requiring adjudication. 
8.3.1 
Time period and frequency for collecting adverse event information 
All AEs and SAEs must be collected from first administration of randomised treatment and until the 
last follow-up visit in accordance with the flowchart (Section 1.2) or whenever, within the above 
time period, the site becomes aware of an AE or SAE.  
 
Conditions present prior to the timepoint from which AEs are collected and anticipated day-to-day 
fluctuations of these conditions, including those identified during screening or during other study-
related procedures performed before exposure to randomised treatment, will be recorded as medical 
history/concomitant illness. 
AE and SAE reporting timelines can be found in Appendix 3 (Section  10.3). All SAEs must be 
recorded and reported to Novo Nordisk within 24 hours, and the investigator must submit any 
updated SAE data to Novo Nordisk within 24 hours of it being available. 
Investigators are not obligated to actively seek for AE or SAE in former study participants. 
However, if the investigator learns of any SAE, including a death, at any time after a participant has 
been discontinued from/completed the study, and the investigator considers the event to be related

to the randomised treatment or related to study participation, the investigator must promptly notify 
Novo Nordisk. 
8.3.2 
Method of detecting adverse events  
The method of recording, evaluating, and assessing causality of AE and SAE and the procedures for 
completing and transmitting SAE reports are provided in Appendix 3 (Section 10.3). 
Care should be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and non-
leading verbal questioning of the participant is the preferred method to inquire about events. 
8.3.3 
Follow-up of adverse events  
After the initial AE/SAE report, the investigator is required to proactively follow each participant at 
subsequent visits/contacts. All SAEs should be followed until final outcome of the event or until the 
participant is lost to follow-up as described in Section 7.3. Further information on follow-up and 
final outcome of events is given in Appendix 3 (Section 10.3). 
8.3.4 
Regulatory reporting requirements for serious adverse events 
Prompt notification by the investigator to Novo Nordisk of an SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of a study 
intervention under clinical investigation are met. 
Novo Nordisk has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study intervention under clinical investigation. Novo 
Nordisk will comply with country-specific regulatory requirements relating to safety reporting to 
the regulatory authority, IRB/IEC, and investigators. This also includes suspected unexpected 
serious adverse reactions (SUSARs). 
An investigator who receives an investigator safety report describing an SAE or other specific 
safety information (e.g., summary or listing of SAEs) from Novo Nordisk will review and then file 
it )476/?1<0<0-16>-;<1/)<7:J;*:7+0=:-)6,?14467<1.A<0-$1.)88:78:1)<-)++7:,16/<7

Pregnancy  
Details of pregnancies in female participants will be collected after first exposure to IMP and until 
the new-born infant is one month of age. For details regarding collection and reporting of pregnancy 
information, please refer to Appendix 4 (Section 10.4). 
8.3.6 
Technical complaints  
Technical complaints will be collected for all products listed on the technical complaint form. 
Instructions for reporting technical complaints can be found in Appendix 5 (Section 10.5). 
In order for Novo Nordisk to perform a complete investigation of reported SAEs, Novo Nordisk 
might ask the investigator to complete a technical complaint form.

The statistical analysis plan (SAP) will be finalised prior to first participant first visit and it will 
include a more technical and detailed description of the statistical analyses described in this section. 
This section is a summary of the planned statistical analyses of the most important endpoints 
including the primary endpoint. 
9.1 
Statistical hypotheses 
The primary objective is to show that IcoSema is superior to semaglutide in terms of change in 
HbA1c (%) from baseline week 0 (V2) to week 52 (V54).

The on-treatment data points set represent data collected in the period in which a participant is 
considered exposed to randomised treatment. 
Baseline assessments are always included in the in-study and on-treatment data points sets. 
The full analysis set and the in-study data points set will be used to estimate the primary estimand. 
9.3 
Statistical analyses 
9.3.1 
General considerations 
Baseline is defined as information collected at week 0 (V2). In case a measurement is not available 
at week 0 (V2) the most recent measurement prior to week 0 (V2) will be used as baseline. 
Presentation of results from a statistical analysis will include the estimated mean treatment 
difference (or ratio) presented together with the two-sided 95% confidence interval and the 
corresponding two-sided p-value. 
In the statistical models, explanatory factors will be coded as follows:  
 Randomised treatment: Once weekly IcoSema, Once weekly semaglutide  
 Region: Asia, Europe, North America, Other 
The regions will be defined as follows: 
 Asia: Japan, China, Taiwan 
 Europe: France, Greece, Slovakia, Switzerland, Sweden, Hungary 
 North America: United States, Canada 
 Other: Russia, Israel, Brazil 
9.3.2 
Primary estimand analysis 
The primary endpoint is change in HbA1c from baseline week 0 (V2) to week 52 (V54). 
The estimand (see Section 3), will be estimated based on the full analysis set using the in-study data 
points set which includes all HbA1c measurements obtained at week 52 (V54) especially 
measurements from participants experiencing intercurrent events. The imputation approach for the 
primary estimand is a multiple imputation similar to the one described by McEvoy.21 
 Missing HbA1c measurements at week 52 (V54) for participants experiencing intercurrent 
events will be imputed from participants experiencing intercurrent events and have a 
measurement at week 52 (V54) in each treatment arm. 
 Missing HbA1c measurements at week 52 (V54) for participants not experiencing intercurrent 
events are imputed from available measurements at week 52 (V54) from participants not 
experiencing intercurrent events in each treatment arm.

The multiple imputation approach will be done the following way:  
 Imputation: An ANCOVA model for change in HbA1c from baseline week 0 (V2) to week 52 
(V54) for participants experiencing intercurrent events and have a measurement at week 52 
(V54) with randomised treatment as fixed factor, last available planned on-treatment HbA1c 
observation without initiation of non-randomised insulin treatment or additional anti-diabetic 
treatments for more than 2 weeks, the time point (study day) of last available planned on-
treatment HbA1c observation without initiation of non-randomised insulin treatment or 
additional anti-diabetic treatments for more than 2 weeks and baseline HbA1c as covariate. If 
participants not experiencing intercurrent events are missing measurements at week 52 (V54) an 
ANCOVA model will be defined in a similar way using available data from participants not 
experiencing intercurrent events. The estimated parameters, and their variances, from the 
imputation models will be used to impute missing HbA1c measurements at week 52 (V54). This 
will be done 1000 times and results in 1000 complete datasets.  
 For each of the complete data sets, the primary endpoint will be analysed using an ANCOVA 
model with region and randomised treatment as fixed factors, and baseline HbA1c as covariate. 
The estimates and standard deviations for the 1000 data sets will be pooled to one estimate and 
);;7+1)<-,;<)6,):,,->1)<176=;16/$=*16J;:=4-22 
 From the pooled estimate and standard deviation the 95% confidence interval for the treatment 
difference will be calculated. The corresponding two-sided p-value will also be calculated. 
This analysis has the underlying assumption that participants with missing data behave similarly as 
comparable participants within the same treatment arm i.e. that participants experiencing 
intercurrent events with missing data at week 52 (V54) behave like participants experiencing 
intercurrent events with data at week 52 (V54) within the same treatment arm and similar for 
participants not experiencing intercurrent events. 
9.3.2.1 
Sensitivity analysis 
The following sensitivity analysis will evaluate the robustness of the results towards the missing 
data assumption. 
For the primary endpoint, a two-dimensional tipping point analysis will be performed where 
participants having imputed HbA1c measurement at week 52 (V54) are assumed to have a worse 
outcome in the IcoSema arm and a better outcome in the semaglutide arm compared to what was 
imputed in the primary analysis. This is done by addi6/7:;=*<:)+<16/>)4=-;Mi to the imputed

Other analyses 
9.3.6.1 
Pharmacokinetic modelling 
Insulin icodec serum concentration data and semaglutide plasma concentration data will be used for 
population PK analysis. The objective of the population PK analysis is to evaluate the effects of 
relevant covariates on insulin icodec and semaglutide exposure. 
The population PK analysis will be performed by Quantitative Clinical Pharmacology, Novo 
Nordisk. A more technical and detailed elaboration of the population PK analysis will be given in a 
modelling analysis plan, which will be prepared before database lock. In brief, previously 
developed PK models for insulin icodec and semaglutide will be applied. The absorption rate 
constants in the models will be fixed, and the apparent clearance and volume of distribution 
parameters will be re-estimated. The covariates of interest will be incorporated into the PK models 
using criteria which will be specified in the modelling analysis plan. 
The population PK analysis will be reported in a separate modelling report, which will not be part 
of the clinical study report. The individual insulin icodec serum concentration data and the 
individual semaglutide plasma concentration data will be tabulated in the bioanalytical report. 
9.4 
Interim analysis 
Not applicable for this study. 
9.5 
Sample size determination 
The sample size is determined in order to have at least 90% power for meeting the primary 
hypothesis. 
It is assumed that the amount of participants experiencing an intercurrent event will be similar to 
what was observed in the subcutaneous semaglutide for T2D development program, and that the 
intercurrent events will have the same impact on effect size and are equally distributed between 
treatment arms. The amount of participants experiencing an intercurrent event ranged from 14.1% 
to 25.7% in open-label studies with various durations except for semaglutide 0.5 mg in the Japan 
studies, see Table  9-1. Based on this the percentage of participants experiencing an intercurrent 
event is expected to be 17%.

CI: Confidence interval, ETD: Estimated treatment difference, Lira: Liraglutide 1.8 mg, IDegLira: insulin 
degludec/liraglutide, SD: Standard deviation. Data from after participants discontinuing randomised treatment were not 
collected in the studies. Change from baseline in HbA1c were analysed using a mixed-effect model for repeated 
measurements. 
However, the current study and the IDegLira studies in Table 9-2 are different in key study design 
asperts such as: in the IDegLira studies the duration was shorter in some of the studies, the 
population was different e.g. in the DUAL I studies previous anti-diabetic treatment was only 
OADs, in study 3851 participants in the GLP-1 comparator arm were asked to continue as their 
prior treatment without adjustment and for participants discontinuing randomised treatment data 
were not collected after discontinuation and hence not included. In addition the statistical method to 
be used in the current study also differs. The differences across development programmes are 
expected to impact the expected treatment differences. Based on these considerations it is 
considered reasonable to be able to detect a treatment difference of at least a -0.33%-point in 
change in HbA1c between the treatment arms for participants not experiencing intercurrent events 
and no treatment difference for participants experiencing intercurrent events. Thus, with 17% of 
participants expected to experience any of the specified intercurrent events before week 52 (V54)

this leads to a mean treatment difference of (1-	K-0.33% = -0.274%-point for the specified 
primary estimand in the overall population. The standard deviation (SD) is assumed to be 1.1%-
point based on the IDegLira studies. 
To be able to detect a treatment difference of -0.274%-point with the above considerations it 
requires 680 participants to ensure 90% power. 
The sample size calculation above is sensitive to the assumptions made for the mean treatment 
difference and standard deviation for superiority for change from baseline in HbA1c, and in 
Table 9-3 the power is presented with different assumptions.

Adjusted treatment difference is adjusted for 17% of participants experiencing intercurrent events. 
From the above assumptions and requirements for the primary analysis, 680 participants will be 
randomly assigned to treatment. This will ensure sufficient marginal power of at least 90% for 
confirming superiority for the primary endpoint.

Partial database lock 
A partial database lock may be performed at the end of the treatment period for all participants, i.e. 
after the date of the last participant last treatment visit. The database will be updated after the partial 
database lock to include remaining safety information. The full database lock will be performed 
after the date of the last participant last visit. 
The analysis of the primary endpoint and all other efficacy endpoints will be performed based on 
the data from the partial database lock. Analysis of safety data will be performed after the full 
database lock. This approach is implemented to allow earlier availability of IcoSema to a T2D 
patient population in need of treatment intensification expected to benefit from an insulin and 
GLP-1 combination product. A detailed plan for data handling and operational aspects of the partial 
database lock and the database update will be finalised before the partial database lock.

study documentation along with an explanation of why it was required. 
10.1.6 
Committees structure 
10.1.6.1 
Novo Nordisk safety committee 
Novo Nordisk will perform ongoing safety surveillance. If new safety signals are identified, these 
will be evaluated by an internal safety committee. The safety committee may recommend 
unblinding of any data for further analysis, and in this case an internal study-independent ad hoc 
group may be established in order to maintain the blinding of the study personnel. 
10.1.6.2 
Event adjudication committee 
An independent external EAC is established to perform ongoing blinded adjudication of selected 
AEs and deaths (see Table 8-1 and Appendix 9 (Section 10.9)). 
The EAC will evaluate events sent for adjudication using pre-defined definitions and guidelines in 
accordance with the EAC charter. The evaluation is based on review of pre-defined clinical data 
collected by the sites. The EAC is composed of permanent members covering all required medical 
specialities. EAC members must disclose any potential conflicts of interest and must be independent 
of Novo Nordisk. The EAC will have no authority to impact study conduct, study protocol or 
amendments. The assessments made by both the event adjudication committee and the investigator 
will be evaluated and included in the CSR. 
10.1.7 
Dissemination of clinical study data 
Study information will be disclosed at clinicaltrials.gov and novonordisk-trials.com and, if 
applicable, also on other national or regional study registries. It will be disclosed according to 
applicable requirements, relevant recommendations or regulations, such as the Declaration of 
Helsinki,23 the International Committee of Medical Journal Editors (ICMJE),25 the Food and Drug 
Administration Amendment Act (FDAAA),26 European Commission Requirements1, 27, 28 and in 
accordance with Novo Nordisk commitment to clinical transparency. If a participant requests to be

Data quality assurance 
10.1.8.1 
Case report forms 
Novo Nordisk or designee is responsible for the data management of this study including quality 
checking of the data. 
To demonstrate his/her oversight of the collected data, the investigator should sign the eCRF on a 
regular basis during the conduct of the study as well as at the end of the study, as described in the 
eCRF completion guideline, and review the HCP web portal. 
All participant data relating to the study will be recorded on CRFs and eDiary unless transmitted 
electronically to Novo Nordisk or designee (e.g., laboratory and eDiary data). The investigator is 
responsible for verifying that data entries are accurate and correct by physically or electronically 
signing the CRF. 
The following will be provided as paper CRFs:

printouts. In addition, the relevant site staff should be available for discussions at monitoring visits 
and between monitoring visits (e.g., by telephone). 
Study monitors will perform ongoing source data verification of critical data points to confirm that 
data entered into the CRF by authorised site personnel are accurate, complete and verifiable from 
source documents. Study monitors will perform ongoing source data review to ensure that the study 
is being conducted in accordance with the current approved protocol and any other study 
agreements, ICH GCP24, and all applicable regulatory requirements, evaluating the adequacy of 
critical processes at site for the execution of the protocol, collection of study data, to ensure that the 
safety and rights of participants are being protected. 
Monitoring will be conducted using a risk-based approach including risk assessment, monitoring 
plans, centralised monitoring (remote assessment of data by Novo Nordisk) and visits to sites. 
Quality tolerance limits (QTLs) will be predefined in the relevant monitoring plan to identify 
systematic issues that can impact participant safety and/or reliability of study results. These 
predefined parameters will be monitored during the study, and important deviations from the QTLs 
and remedial actions taken will be summarised in the clinical study report. 
Monitors will review the participantJ;5-,1+)4:-+7:,;)6,7<0-:;7=:+-,)<)<7-6;=:-+76;1;<-6+A
and/or identify omissions compared to the eCRF.  
10.1.8.3 
Protocol compliance 
Deviations from the protocol should be avoided. If deviations do occur, the investigator must 
inform the monitor without delay and the implications of the deviation must be reviewed and 
discussed. 
Deviations must be documented and explained in a protocol deviation by stating the reason, date, 
and the action(s) taken. Some deviations, for which corrections are not possible, can be 
acknowledged and confirmed via edit checks in the CRF or via listings from the study database.

10.1.11 Study and site closure 
Novo Nordisk reserves the right to close the site or terminate the study at any time for any reason at 
the sole discretion of Novo Nordisk. If the study is suspended or terminated, the investigator must 
inform the participants promptly and ensure appropriate therapy and follow-up. The investigator 
and/or Novo Nordisk must also promptly inform the regulatory authorities and IRBs/IECs and 
provide a detailed written explanation. 
Sites will be closed upon study completion. A site is considered closed when all required documents 
and study supplies have been collected and a site closure visit has been performed. 
The investigator may initiate site closure at any time, provided there is reasonable cause and 
sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of a site by Novo Nordisk or investigator may include but are not 
limited to: 
 failure of the investigator to comply with the protocol, the requirements of the IRB/IEC or local 
health authorities, Novo Nordisk procedures or GCP guidelines 
 inadequate recruitment of participants by the investigator 
 discontinuation of further study intervention development.

conduct of the study and to protect the rights, safety, and well-being of the participants. 
A qualified physician, who is an investigator or a sub investigator for the study, must be responsible 
for all study-related medical decisions. 
The investigator is responsible for filing essential documents (i.e., those documents which 
individually and collectively permit evaluation of the conduct of a study and the quality of the data 
produced) in the investigator trial master file. The documents, including the participant 
identification code list must be kept in a secure locked facility so that no unauthorised 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. This also 
includes ensuring that no indirect sharing of user credentials for IT systems used in this study takes 
place (e.g., by not sharing IT equipment with others in a way where user credentials have the 
possibility of being shared). 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 
participants to a specific qualified physician who will be readily available to participants 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). 
10.1.13 Indemnity statement 
Novo Nordisk carries product liability for its products, and liability as assumed under the special

Authorship of publications should be in accordance with the Recommendations for the Conduct, 
Reporting, Editing and Publication of Scholarly Work in Medical Journals by the International 
Committee of Medical Journal Editors.29 
All authors will be provided with the relevant statistical tables, figures, and reports needed to 
evaluate the planned publication. 
Where required by the journal, the investigator from each site will be named in an 
acknowledgement or in the supplementary material, as specified by the journal.  
10.1.14.3 
Site-specific publication(s) by investigator(s) 
For a multicentre clinical study, analyses based on single-site data usually have significant 
statistical limitations and frequently do not provide meaningful information for healthcare 
professionals or participants, and therefore may not be supported by Novo Nordisk. Thus, Novo 
Nordisk may deny a request or ask for deferment of the publication of individual site results until 
the primary manuscript is accepted for publication. In line with Good Publication Practice, such 
individual reports should not precede the primary manuscript and should always reference the 
primary manuscript of the study. 
10.1.14.4 
Investigator access to data and review of results 
As owner of the study database, Novo Nordisk has the discretion to determine who will have access 
to the database. 
Individual investigators will have their own research participa6<;J,)<))6,?144*-8:7>1,-,?1<0

Appendix 2: Clinical laboratory tests 
The tests detailed in Table 10-1 and Table 10-2 will be performed by the central laboratory and by 
the special laboratories. 
Additional tests may be performed at any time during the study as determined necessary by the 
investigator or required by local regulations. Only laboratory samples specified in the protocol 
should be sent to the central laboratory for analysis; if additional laboratory sampling is needed, 
e.g., to follow-up on AEs, this must be done at a local laboratory. 
The central laboratory will communicate to the investigator abnormal values of parameters not 
requested in the protocol but identified by the laboratory equipment and/or their processes 
according to their laboratory Standard Operating Procedures. These data will not be transferred to 
the study database. The investigator should review such values for AEs and report these according 
to this protocol. 
The investigator must review all laboratory results for concomitant illnesses and AEs,with the 
exception of the pharmacokinetics and antibodies (sections 8.4 and 8.7.1), as these results will not 
be available to the investigator until after finalisation of the clinical study report. 
The investigator must keep an overview, e.g. a log, of laboratory samples not handled according to 
the laboratory manual. In addition, the investigator must keep an overview, e.g. a log, of laboratory 
samples stored at site. 
Laboratory samples will be destroyed no later than at the end of the study or no later than at 
finalisation of the CSR. 
Human bio samples will be stored as described in Appendix 6 (Section 10.6).

Appendix 3: Adverse Events and Serious Adverse Events: Definitions and procedures 
for recording, evaluating, follow-up, and reporting 
10.3.1 
Definition of adverse event 
An AE is any untoward medical occurrence in a clinical study participant that is temporally 
associated with the use of IMP, whether or not considered related to the IMP. An AE can therefore 
be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom or 
disease (new or exacerbated) temporally associated with the use of an IMP. 
Events to be reported as AEs: 
 Any abnormal laboratory test results or safety assessments considered clinically significant in 
the medical and scientific judgment of the investigator, including events that have worsened 
from prior to the time point from which AEs are collected 
 Conditions detected or diagnosed after IMP administration even though it may have been 
present prior to the time point from which AEs are collected 
 Exacerbation/worsening of a chronic or intermittent condition including either an increase in 
frequency and/or intensity of the condition 
 Signs, symptoms or the clinical sequelae of a suspected drug-drug interaction 
 Signs, symptoms or the clinical sequelae of a suspected overdose of IMP regardless of intent

AE or SAE. Such instances will be captured in the efficacy assessments. However, the signs, 
symptoms and/or clinical sequelae resulting from lack of efficacy will be reported as AE or SAE if 
they fulfil the definition. 
Events NOT to be reported as adverse events: 
 Conditions present prior to the time point from which AEs are collected and anticipated day-to-
day fluctuations of these conditions. This includes those conditions identified during screening 
or identified during other study procedures performed before exposure to IMP.  
Note: Conditions present or occurring prior to the time point from which AEs are collected 
should be recorded as concomitant illness/medical history. 
 Medical or surgical procedures (e.g., endoscopy, appendectomy). The condition that leads to the 
procedure is the AE. 
 Medical or surgical procedures not preceded by an AE or worsening of a known condition. 
10.3.2 
Definition of a serious adverse event 
An SAE is any untoward medical occurrence that fulfils at least one of the following criteria:

 Hospitalisation for elective treatment (e.g., elective medical or surgical procedures) 
of a condition that was present prior to the time point from which AEs are collected, 
and that did not worsen, is not considered an AE.

constitute AEs and should therefore not be reported as AEs or SAEs. Hospital admissions for 
medical or surgical procedures, planned before study inclusion, are not considered AEs or SAEs

vomiting, diarrhoea, influenza, and accidental trauma (e.g., sprained ankle), that may 
interfere with or prevent everyday life functions but do not constitute a substantial 
disruption.

 Important medical event: 
 Medical or scientific judgment should be exercised by the investigator in deciding 
whether SAE reporting is appropriate in other situations. This includes important 
medical events that may not be immediately life-threatening or result in death or 
hospitalisation but may jeopardise the participant or may require medical or surgical 
intervention to prevent one of the other outcomes listed in the above definition. 
These events should usually be considered serious and reported as SAEs using the 
important medical event criterion. 
 The following must be reported as an SAE using the important medical event 
criterion if no other seriousness criteria are applicable:

10.3.3 
Description of adverse events requiring additional data collection and other events 
requiring collection of additional information  
Adverse events requiring additional data collection 
An AE requiring additional data collection is an AE where Novo Nordisk has evaluated that 
additional data is needed in the evaluation of safety. A specific event form needs to be completed 
for these events.  
Medication error: 
 A medication error is an unintended failure in the IMP treatment process that leads to, or has the 
potential to lead to, harm to the participant, such as: 
 administration of wrong drug 
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 subcutaneous 
 accidental administration of a lower or higher dose than intended. The administered dose 
must deviate from the intended dose to an extent where clinical consequences for the study 
participant were likely to happen as judged by the investigator, although they did not 
necessarily occur. 
Misuse and abuse: 
 Situations where the IMP is intentionally and inappropriately used not in accordance with the 
protocol (e.g., overdose to maximise effect) 
 Persistent or sporadic, intentional excessive use of an IMP which is accompanied by harmful 
physical or psychological effects (e.g., overdose with the intention to cause harm) 
Note: Medication error, misuse and abuse must always be reported on an AE form and a specific 
event form must be completed. The AE diagnosis on the AE form must reflect what occurred (e.g., 
accidental overdose, intentional overdose or other). If the medication error and/or misuse and abuse 
resulted in a clinical consequence, this must be reported on an additional AE form. 
Hypersensitivity: 
Systemic hypersensitivity can be manifested as isolated symptoms such as urticaria, angioedema, 
conjunctivitis, rhinitis, bronchospasm, gastrointestinal symptoms (nausea, vomiting, diarrhoea, 
abdominal pain), or as anaphylaxis or anaphylactic shock. 
Anaphylaxis is an acute, potentially lethal, multisystem syndrome resulting from the sudden release 
of mast cell- and basophil-derived mediators into the circulation.30 It most often results from 
immunologic reactions to foods, medications, and insect stings, although it can also be induced 
through nonimmunologic mechanisms by any agent capable of producing a sudden, systemic 
degranulation of mast cells or basophils31. Characteristic symptoms and signs, occurring minutes to 
a few hours after exposure to potential triggering agents or events may include: flushing, urticaria, 
angioedema, hoarseness, throat tightness, stridor, wheezing, coughing, shortness of breath, 
abdominal pain, vomiting, and/or hypotension, dizziness or collapse.

Local hypersensitivity reactions, including rash, redness, pruritus and oedema, may occur at the site 
of investigational drug injection. 
Drug hypersensitivity reactions are the adverse effects of pharmaceutical formulations (including 
active drugs and excipients) that clinically resemble allergy.32 They can be allergic and non-allergic. 
If a hypersensitivity event is suspected, the participants must contact the site staff as soon as 
possible for further guidance. All events must be reported, and in case of systemic hypersensitivity, 
additional information must be provided on a separate form.  
Injection site reactions: 
If an event of injection site reaction is observed, additional information must be obtained if 
available on a separate form. 
 
Acute gallbladder diseases: 
Events of symptomatic acute gallbladder disease (including gallstones and cholecystitis) 
Malignant neoplasms: 
Confirmed malignant neoplasm by histopathology or other substantial clinical evidence 
Other events requiring collection of additional information 
Hypoglycaemic episodes  
All hypoglycaemic episodes must be recorded by the participant in the eDiary. Instructions on how 
to transfer SMPG values to the eDiary will be given to the participants. If the hypoglycaemic 
episode fulfils the criteria for an SAE the investigator/site must report it as such. One AE form and 
safety information form can cover several hypoglycaemic episodes, if the participant has not 
recovered between the episodes. For more information on hypoglycaemic episodes, please refer to 
Appendix 10.7. 
10.3.4 
Recording and follow-up of adverse event and/or serious adverse event 
10.3.4.1 
Adverse event and serious adverse event recording 
The investigator will record all relevant AE/SAE information in the CRF. 
The investigator will attempt to establish a diagnosis of the event based on signs, symptoms, and/or 
other clinical information. In such cases, the diagnosis (not the individual signs/symptoms) will be 
documented as the AE/SAE. 
When an AE/SAE occurs, it is the responsibility of the investigator to review all documentation 
(e.g., hospital progress notes, laboratory and diagnostics reports) related to the event. 
There may be instances when copies of source documents (e.g., medical records) for certain cases 
are requested by Novo Nordisk. In such cases, all participant identifiers, with the exception of the 
subject ID, must be redacted on the copies of the source documents before submission to Novo 
Nordisk.

Novo Nordisk products used as concomitant medication or NIMP: if an AE is considered to have a 
causal relationship with a Novo Nordisk marketed product used as NIMP or concomitant 
medication in the study, it is important that the suspected relationship is reported to Novo Nordisk, 
e.g., in the alternative aetiology section on the safety information form. Novo Nordisk may need to 
report this AE to relevant regulatory authorities. 
10.3.4.2 
Assessment of severity 
The investigator will assess severity for each event reported during the study and assign it to one of 
the following categories: 
 Mild: An event that is easily tolerated by the participant, causing minimal discomfort and not 
interfering with everyday activities. 
 Moderate: An event that causes sufficient discomfort and interferes with normal everyday 
activities. 
 Severe: An event that prevents normal everyday activities.  
Note: An AE that is assessed as severe should not be confused with an SAE. Both AEs and 
SAEs can be assessed as severe. 
10.3.4.3 
Assessment of causality 
The investigator is obligated to assess the relationship between IMP and the occurrence of each 
AE/SAE. The investigator will use clinical judgment to determine the relationship.  
Relationship between an AE/SAE and the relevant IMP should be assessed as:  
 Probable - Good reason and sufficient documentation to assume a causal relationship. 
 Possible - A causal relationship is conceivable and cannot be dismissed. 
 Unlikely - The event is most likely related to aetiology other than the IMP. 
Alternative aetiology, such as underlying disease(s), concomitant medication, and other risk factors, 
as well as the temporal relationship of the event to IMP administration, should be considered and 
investigated.

products, for the assessment. For each AE/SAE, the investigator must document in the medical 
records that he/she has reviewed the AE/SAE and has provided an assessment of causality. 
There may be situations in which an SAE has occurred, and the investigator has minimal 
information to include in the initial report. However, it is important that the investigator always 
makes an assessment of causality for every event before the initial transmission of the SAE 
data. 
The investigator may change his/her opinion of causality, in light of follow-up information, and 
update the causality assessment in the CRF.

The causality assessment is one of the criteria used when determining regulatory reporting 
requirements 
10.3.4.4 
Final outcome 
The investigator will select the most appropriate outcome: 
 Recovered/resolved: The participant has fully recovered, or by medical or surgical treatment 
the condition has returned to the level observed when first documented 
 Recovering/resolving: The condition is improving, and the participant is expected to recover 
from the event.  This term may also be applicable for AEs ongoing at the time of death (where 
death was due to another AE). 
Note: For SAEs, this term is only applicable if the participant has completed the follow-up 
period and is expected to recover. 
 Recovered/resolved with sequelae: The participant 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 participant has not improved, and the 
symptoms are unchanged, or the outcome is not known. This term may be applicable in cases of 
chronic conditions, cancer or AEs ongoing at time of death (where death is due to another AE). 
 Fatal: This term is only applicable if the participant died from a condition related to the 
reported AE. Outcomes of other reported AEs in a participant before he/she died should be

Follow-up of adverse event and serious adverse event 
The investigator is obligated to perform or arrange for the conduct of supplemental measurements

investigator should, upon request, provide Novo Nordisk with a copy of the autopsy report 
including histopathology.

For SAEs, initial notification via telephone is acceptable, although it does not replace the need for 
the investigator to complete the AE and safety information forms within the designated reporting 
timelines (see Figure 10-1): 
 AE form within 24 hours 
 Safety information form within 5 calendar days 
 AE form and safety information form must be signed within 7 calendar days after first 
knowledge by the investigator. 
 Specific event form within 14 calendar days. 
 For timelines related to events for adjudication, refer also to Appendix 9 (Section 10.9) and 
Figure 10-1. 
If the eCRF is unavailable for more than 24 hours, then the sites will use the paper AE form, and if 
the eCRF is unavailable for more than 5 calendar days, then the site will use the paper safety 
information form. The site should enter the SAE data in the eCRF as soon as it becomes available. 
The relevant CRF forms (AE and safety information forms) must be forwarded to Novo Nordisk in 
accordance with Section 10.1.5. 
After the study is completed, the study database will be locked, and the CRF will be 
decommissioned to prevent the entry of new data or changes to existing data.  If a site receives a 
report of a new SAE from a participant or receives updated information on a previously reported 
SAE after CRF decommission, the site can report this information on a paper AE and safety 
information form (see below) or to Novo Nordisk by telephone.

Appendix 4: Contraceptive guidance and collection of pregnancy information 
10.4.1 
Definitions 
Woman of childbearing potential (WOCBP) 
A woman is considered fertile following menarche and until becoming postmenopausal unless 
permanently sterile. 
If fertility is unclear (e.g., amenorrhea in adolescents or athletes), and a menstrual cycle cannot be 
confirmed before first dose of study intervention, additional evaluation should be considered. 
Females in the following categories are not considered WOCBP 
1. Premenarcheal 
2. Females with one or more of the following: 
 
Documented total hysterectomy 
 
Documented bilateral salpingectomy 
 
Documented bilateral oophorectomy 
For females with permanent infertility due to an alternate medical cause other than the above 
(e.g., Müllerian agenesis, androgen insensitivity), investigator discretion should be applied in 
determining study enrolment. 
3. Postmenopausal female: 
 A postmenopausal state is defined as amenorrhoea for at least 12 months without an 
alternative medical cause in a female > 45 years of age.  Alternative medical causes for 
amenorrhoea include, but are not limited to, hormonal contraception or hormonal 
replacement therapy.  
 -5)4-;EA-):;7.)/-+)6*-+76;1,-:-,87;<5-678)=;)4 
Females on hormone replacement therapy and whose menopausal status is in doubt are considered 
of childbearing potential and will be required to use one of the highly effective contraception 
methods.

Contraceptive guidance 
Male participants 
No contraception measures are required as the risk of teratogenicity/fetotoxicity caused by transfer 
of insulin icodec or semaglutide in seminal fluid is unlikely.33   
Female participants  
Female participants of childbearing potential are eligible to participate if they agree to use methods 
of contraception consistently and correctly. Table 10-3 lists the highly effective methods of 
contraception allowed. Local regulations may apply, see Appendix 11 (Section 10.11). 
Highly effective contraception should be utilised until the end of treatment.

Highly effective contraception should be utilised for a least 35 days after last dose of IMP 
(corresponding to time during treatment and until the end of relevant systemic exposure). 
Table 10-3 
Highly effective contraceptive methods allowed34

 oral 
 injectable 
 implantable 
 Intrauterine device (IUD)

 Bilateral tubal occlusion 
 Vasectomized partner 
Vasectomized partner is a highly effective contraceptive method provided that the partner is the sole sexual partner 
of the woman of childbearing potential, and the absence of sperm has been confirmed. If not, an additional highly 
effective method of contraception should be used. Spermatogenesis cycle is approximately 90 days. 
 Sexual abstinence 
Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual 
intercourse during the entire period of risk associated with the study intervention. The reliability of sexual 
abstinence needs to be evaluated in relation to the duration of the study and the preferred and usual lifestyle of the 
participant. 
NOTES 
a. Contraceptive use by men or women should comply with local regulations regarding the use of contraceptive 
methods for those participating in clinical studies. 
b. If locally required, in accordance with Clinical Trial Facilitation Group guidelines, acceptable contraceptive 
methods are limited to those which inhibit ovulation as the primary mode of action. 
The following methods are not acceptable methods of contraception: Periodic abstinence (calendar, 
symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and 
lactational amenorrhoea method (LAM).

collect follow-up information on participant and neonate which will be forwarded to Novo Nordisk 
within 14 calendar days. Generally, follow-up will not be required for longer than 1 month beyond 
the delivery date. 
Any termination of pregnancy will be reported, regardless of foetal status (presence or absence of 
anomalies) or indication for procedure.

Appendix 5: Technical complaints: Definition and procedures for recording, 
evaluation, follow-up and reporting 
10.5.1 
Definition of technical complaint 
A technical complaint is any written, electronic or oral communication that alleges product 
(medicine or device) defects. The technical complaint may be associated with an AE but does not 
concern the AE itself.  
Examples of technical complaints: 
 Problems with the physical or chemical appearance of IMPs or auxiliary supplies (e.g., 
discoloration, particles or contamination) 
 Problems with packaging material including labelling 
 Problems related to devices (e.g., to the injection mechanism, dose setting mechanism, push 
button or interface between the pen-injector and the needle) 
Time period for detecting technical complaints 
All technical complaints which occur from the time of receipt of the product at site until the time of 
the last usage of the product must be collected for products predefined on the technical complaint 
form. 
10.5.2 
Recording and follow-up of technical complaints 
Reporting of technical complaints to Novo Nordisk 
For contact details for Customer Complaint Center, please refer to Attachment I. 
Technical complaints on products allocated to a participant must be reported on a separate technical 
complaint form: 
1. For products with DUN: One technical complaint form must be completed for each affected 
DUN. 
2. For products without DUN: One technical complaint form must be completed for each batch, 
code or lot number. 
Timelines for reporting technical complaints to Novo Nordisk 
The investigator must complete the technical complaint form in the CRF within: 
 24 hours if related to an SAE 
 5 days calendar for all other technical complaints  
If the CRF is unavailable, or when reporting a technical complaint on a product that is not yet 
allocated to a participant, the information must be provided on a paper form to Customer Complaint 
Center, Novo Nordisk, within the same timelines as stated above. When the CRF becomes available 
again, the investigator must enter the information on the technical complaint form in the CRF.

originally completed form. 
Collection, storage and shipment of technical complaint samples  
The investigator must collect the technical complaint sample and all associated parts and notify the 
monitor within 5 calendar days of obtaining the sample at site. The sample and all associated parts 
must be sent as soon as possible to Customer Complaint Center, Novo Nordisk, together with a 
copy of the completed technical complaint form. The technical complaint sample should contain the 
batch, code or lot number and, if available, the DUN. If the technical complaint sample is 
unobtainable, the reason must be stated on the technical complaint form. If several samples are 
shipped in one shipment, the sample and the corresponding technical complaint form should be kept 
together. 
Storage of the technical complaint sample must be done in accordance with the conditions 
prescribed for the study intervention.

Appendix 6: Retention of human biosamples 
Hypersensitivity reaction samples 
In case of a systemic hypersensitivity reaction, the additional blood samples taken in relation to the 
reaction (Section 8.7 and 10.2)  may be retained to follow-up on the hypersensitivity reaction. If 
deemed relevant by Novo Nordisk, relevant exploratory tests may be performed, e.g. histamine 
release (basophil activation). If measured, such data will be reported in a separate report. 
The samples will be stored at a central laboratory, at a central storage facility, and/or at an analysing 
laboratory contracted by Novo Nordisk. The samples might be transferred to other countries, if not 
prohibited by local regulations. Only Novo Nordisk staff and bio-repository personnel will have 
access to the stored samples. The samples may be shipped to a contract research organisation for 
analysis. 
The samples will be anonymised (identified only by a unique sample ID, visit number, study 
identification number and sampling date). Confidentiality and personal data protection will be 
ensured during storage after the end of the study and no direct identification of the participant will 
be stored together with the samples.  
Potential further analyses of the samples will not have any consequences for the participant and 
their relatives. Participants can contact the investigator if they wish to be informed about results 
derived from stored antibody samples obtained from their own body. 
The samples will be stored at Novo Nordisk or a Novo Nordisk designated referral central 
bio-repository after the end of the study and until marketing authorisation approval or until the 
research project terminates, but no longer than 15 years from the end of the study, after which they 
will be destroyed. 
Antibody samples  
Antibody samples may be retained for later analysis for further characterisation of antibody 
responses towards drug, if required by health authorities or for safety reasons. A fraction of the 
individual participant samples may be pooled and used for further development of antibody assays, 
or for generating reagents for in study validation and control of future assay performance. 
The antibody samples will be stored at Novo Nordisk or at a designated referral central 
bio-repository after the end of the study and until marketing authorisation approval or until the 
research project terminates, but no longer than 15 years from the end of the study after which they 
will be destroyed. 
Metabolism samples (PK samples) 
Samples for metabolism analysis may be retained for later analysis of metabolites if needed. The 
samples will be stored at Novo Nordisk or at a designated referral central bio-repository after end of 
study and until marketing authorisation approval or until the research project terminates, but no 
longer than 15 years from end of study after which they will be destroyed.

defined by Seaquist40 and ISPAD.37 
 
Severe hypoglycaemia 
1Severe hypoglycaemia is an event requiring assistance of another person to actively administer 
carbohydrates, glucagon, or take other corrective actions. Plasma glucose concentrations may not be 
available during an event, but neurological recovery following the return of plasma glucose to 
normal is considered sufficient evidence that the event was induced by a low plasma glucose 
concentration.40 
Nocturnal hypoglycaemia 
Nocturnal hypoglycaemic episodes: episodes occurring between 00:01 and 05:59 both inclusive. 
Reporting of hypoglycaemic episodes 
 
Reporting of hypoglycaemic episodes by BG meters: 
Plasma glucose (PG) should always be recorded in the (e)diary when a hypoglycaemic episode is 
suspected. 
 
When a participant experiences a hypoglycaemic episode, the participant should record the general 
information in relation to the hypoglycaemia (timing, PG measurements, symptoms, etc.) as 
described in the e-diary. The investigator should ensure correct reporting of the hypoglycaemic 
episode. In case a participant is not able to fill in the e-diary (e.g., in case of hospitalisation), the 
investigator should still report the hypoglycaemic episode on the hypoglycaemic episodes form. 
Upon onset of a hypoglycaemic episode the participant is recommended to measure PG every 15

value for the hypoglycaemic episode, but the start time of the episode will remain as the time for the 
first low PG value and/or symptom. The remaining values will be kept as source data. 
If the severity of a hypoglycaemic episode changes, only one hypoglycaemic episode will be 
reported, reflecting the most severe degree of hypoglycaemia.

the event was induced by a low PG concentration.40 
Please refer to Section 10.3.3 for information regarding reporting of hypoglycaemia in the eDiary. 
Diary review 
At each contact the investigator must review the diary data for correct reporting of PG values and 
hypoglycaemic episodes. In case of incomplete or incorrect data in the diary, the participant must be 
questioned whether there have been any severe hypoglycaemic episodes since the last visit and 
report accordingly. 
Re-training of participants 
The participant must be re-trained in how to report hypoglycaemic episodes if the investigator 
identifies low PG values not reported as hypoglycaemic episodes. The training should be 
documented by the investigator in source documents.

Appendix 8: Titration guideline 
Titration guidelines have been developed, providing recommended dose adjustments at different PG 
levels to ensure that participants receive an optimal treatment. However, it is recognised that 
treatment with insulin and combination products containing insulin should be individualised, and 
the specific titration algorithms may not be applicable in certain clinical situations. Hence, it is 
important that other information, such as symptoms of hypo/hyperglycaemia, previous response to 
dose adjustments, other glucose measurements and other indicators of the participantJ;4->-47.
glycaemic control, is taken into consideration when decisions on dosing are made. In addition, since 
this is a superiority study, it is important that the semaglutide is dose optimised. The investigator is 
responsible for the treatment of the participants and can therefore overrule the guidelines to avoid 
safety hazards. 
Initiation of trial products 
At randomisation eligible participants will be randomised to receive IcoSema or semaglutide. 
IcoSema should be taken once weekly at the same day of the week. The starting dose at 
randomisation (V2) will be 40 dose steps, which is equivalent to 40 units of insulin icodec and 
0.114 mg of semaglutide. 
Semaglutide should be taken once weekly at the same day of the week. The starting dose should be 
0.25 mg.  
The first dose of IcoSema or semaglutide should be administered at least 5 days after the last dose 
of pre-trial weekly GLP-1 receptor agonist. The first dose of IcoSema or semaglutide can be 
administered the following day after the last dose of pre-trial daily GLP-1 receptor agonist. 
IcoSema dose adjustment during the study 
After randomisation IcoSema should be adjusted once weekly by the investigator in connection 
with the visits/phone contacts. 
The dose adjustment will be based on the three pre-breakfast SMPG values measured on two days 
prior to the dose adjustment and on the day of the contact. 
If one or more pre-breakfast SMPG values are missing, the dose adjustment should be performed on 
the remaining SMPG value(s). 
Adjustment of IcoSema will be done in accordance with Table 10-5.

Semaglutide dose adjustment during the study 
After 4 weeks of treatment with 0.25 mg, the dose should be increased to 0.5 mg once-weekly. 
After at least 4 more weeks the dose should be increased to 1 mg once-weekly.  
If adverse events occur, the escalation to 1 mg can be extended up to 26 weeks after randomisation.  
Dose reductions of semaglutide from 1 mg to 0.5 mg is allowed in case of safety concern or 
unacceptable intolerability. 
Novo Nordisk should follow up every four weeks (from V2) to ensure that the maximum tolerated 
dose is reached for the individual participant. 
Deviations from the algorithm 
It is recommended that the algorithm is followed. However, it is also important that the decision to 
adjust doses is based on all relevant information. A reason for deviating from the algorithm should 
be entered into the HCP portal by the investigator, as applicable.

inject the planned dose. If the dose is missed for > 3 days, the participants should await the next 
planned day of injection. Please note that the visit window is +/- 3 days. 
Missing semaglutide dose guidance 
If a semaglutide dose is missed, it should be administered as soon as possible and within 5 days 
after the missed dose. If more than 5 days have passed, the missed dose should be skipped, and the 
next dose should be administered on the regularly scheduled day. In each case, participant can then 
resume their regular once weekly dosing schedule. 
Dose recommendation from end of treatment and during follow-up 
IcoSema treated participants 
If it is decided that the participant should continue basal insulin treatment after end of study it is 
recommended that the participant is switched from IcoSema to any available basal insulin at the 
discretion of the investigator. Regarding switch from IcoSema to post-study basal insulin the 
following should be considered: 
 Calculate the new daily basal insulin dose by dividing the latest IcoSema dose in dose step 
by 7. 
 Initiate the new daily basal insulin two weeks after the last injection of IcoSema. 
 Continue to measure pre-breakfast SMPG daily in the follow-up period. If pre-breakfast 
SMPG exceeds 10.0 mmol/L (180 mg/dL), it should be considered to initiate the daily basal 
insulin dose earlier than two weeks after the last dose of IcoSema. 
 Consider titrating the basal insulin once or twice weekly according to the pre-breakfast 
SMPG values and the local label of the chosen insulin.

If it is decided that the participant is switched to a GLP-1 receptor agonist, the start should also 
await two weeks off IcoSema. Thereafter, the treatment can be initiated in accordance with local 
label for the individual product. 
Semaglutide treated participants 
If it is decided to continue semaglutide treatment, the participant can continue with the same 
semaglutide dose as during the study. If it is decided to continue with another GLP-1 analogue, the 
initiation should be in accordance with the local label of said GLP-1 analogue.

 Hypoglycaemia information 
 
It is important that titration data are entered into the eDiary and into the eCRF in a timely manner, 
as the aim is to reduce the time in which the participant may receive inadequate treatment. 
The titration data should be reviewed by Novo Nordisk within 24 hours (on workdays). Novo 
Nordisk may contact the investigator by phone or via an online portal (CONNECT) after e-mail 
notification to clarify reasons for deviation or to request entry of missing data. When the 
investigator receives an inquiry, a response should be received at Novo Nordisk within 24 hours (on 
workdays). 
Novo Nordisk will also monitor changes in HbA1c!7>7!7:,1;3J;5-,1+)4;<)..5)A>1:<=)44A
visit at regular intervals to discuss progress in glycaemic control and titration of individual 
participants.

Appendix 9:  Events requiring adjudication 
Event adjudication will be performed in randomised participants. An event for adjudication is a 
selected AE or death evaluated by an independent external Event adjudication committee (EAC) in 
a blinded manner, please refer to Table 10-6 for event types in scope.  
For details on the EAC, refer to Appendix 1 (Section 10.1.6.2). 
Table 10-6 
Adverse events requiring event adjudication 
Event type (AE category) 
(serious and non-serious AEs) 
Description  
Death 
 All cause death  
Acute coronary syndrome (acute myocardial 
infarction and unstable angina pectoris requiring 
hospitalisation) 
 All types of acute myocardial infarction and unstable angina 
pectoris requiring hospitalisation 
Cerebrovascular event (stroke and transient 
ischemic attack) 
 Episode of focal or global neurological dysfunction that could be 
caused by brain, spinal cord, or retinal vascular injury as a result 
of haemorrhage or ischemia, with or without infarction 
Heart failure (requiring hospitalisation and 
urgent heart failure visits) 
 New episode or worsening of existing heart failure leading to an 
urgent, unscheduled hospital admission or 
clinic/office/emergency department visit 
 
There are four ways to identify events relevant for adjudication as described below: 
1. Investigator-reported events for adjudication: investigator selects the appropriate AE category 
relevant for adjudication (see Table 10-6). 
2. AEs reported with fatal outcome 
3. AE search (standardised screening): All AEs not reported with an AE category relevant for 
adjudication will undergo screening to identify potential events for adjudication. Investigators 
will be notified of these events in the CRF. 
4. EAC-identified events: Unreported events relevant for adjudication identified by the EAC 
during review of source documents provided for another event for adjudication. Investigators 
will be notified of these events in the CRF and has the option to report the EAC-identified 
event. 
For each event relevant for adjudication, an event type specific adjudication form should be 
completed in the CRF within 14 days (Figure 10-1). 
Copies of source documents should be uploaded to the EAS as soon as possible and preferably 
within 4 weeks (Figure 10-1). In cases where the EAS is not accessible for document upload, the 
investigator should ensure that the relevant source documents are collected and saved locally until 
the EAS is available. If no, or insufficient source documents are provided to the adjudication 
supplier, the investigator can be asked to complete a clinical narrative to be uploaded to the EAS. 
If new information becomes available for an event sent for adjudication, it is the responsibility of 
the investigator to ensure the new information is uploaded to the EAS.

10.10 Appendix 10: Mitigations to ensure participant safety and data integrity during an 
emergency situation 
10.10.1 Definition and scope of appendix 
A major emergency is defined as a situation that causes substantial restrictions to study site access 
for participants and/or sponsor representatives. 
In case local restrictions due to a major emergency, e.g. due to a COVID-19 outbreak, lead to lock-
down of a site, the site must contact Novo Nordisk to allow for implementation of mitigations 
mentioned in this appendix based on mutual agreement. 
According to local regulation, health authorities and independent ethics committees should be 
notified in case elements of the emergency appendix are activated. 
Table 10-7 indicates the minimum requirements for assessments that should be performed during a 
lock-down, but sites should always try to follow the assessments outlined in the original flowchart 
(Section 1.2) to the extent possible. Implementation of specific mitigations should be based on 
assessment of feasibility at the individual site.  
Alternative visit formats are examples of the mitigations that can be implemented: 
 Home visits: visits to be performed at the participant´s home  
 Off-site visits: visits to be performed at a place other than the site or the participant´s home  
Alternative visit formats and all other mitigations mentioned in this appendix can be implemented 
only if allowed and deemed feasible according to local regulations, requirements and/or guidelines 
at the sites and countries and should be performed by the site-staff. As a pre-requisite, sites need to 
ensure that the study site staff is covered by workers' compensation insurance, also when 
performing home and off-site visits. 
Sites should comply with local regulations, requirements and/or guidelines if they are issued. 
10.10.2 Visits 
Screening (V1) and randomisation/baseline (V2) should always be performed as on-site visits. If a 
site is unable to perform these visits on-site, screening and randomisation of new participants at that 
site should be on hold until on-site visits are possible. 
Visits 4 and 8 should always be performed as on-site visits to ensure collection of, at least, 
antibodies and PK samples.  
The visit at week 52 (V54) should always be performed as on-site visit. The visit window can be 
extended for up to 28 days. Participants should continue randomised treatment until the visit at 
week 52 (V54) takes place.  
The last follow-up visit (V56) should always be performed as on-site visit to ensure, at least, 
collection of antibodies and PK samples.

On-site visits (visits V3, V5, V6, V10, V12, V16, V20, V24, V28, V30, V34, V38, V42, V46, V50, 
V55) can be converted to remote visits (video, phone or similar) or home or off-site visits.  
At each visit, the investigator must indicate in the CRF how the visit was performed and specify the 
reason for the preferred assessment method. 
10.10.3 Assessments 
Assessments used for safety or the confirmatory endpoints (i.e., HbA1c) should be prioritised, as 
well as antibodies and PK. The preferred order for the method of assessment is shown in 
Table 10-7): 
HbA1c should be prioritised and be performed on-site at least at V1, V2 and V54. 
Antibodies and PK should be prioritised and be performed on-site at least at V2 (antibodies only), 
V4, V8, V54 and V56.  
Specifications regarding how to perform these assessments using remote visits (phone visits or 
video contact) or as home visits or off-site visits will be provided by Novo Nordisk or the vendor.  
All laboratory samples should be analysed at the central and special laboratories.  In case of lock 
down of the site, samples of V1, V2, V4, V8, V54 and V56 should be prioritised, and the Lack of 
Efficacy Criteria 5, Section 7.1.1 would be evaluated based on the SMPG only (instead of 
evaluating based on SMPG and FPG).  
Home measurements of pregnancy tests and vital signs (other than the ones to be collected at V1, 
V2 and V54) can be performed if on-site visits are not possible and if deemed feasible for the 
participant. Only findings meeting the definition for an AE (refer to Appendix 3 [Section 10.3]) 
should be reported in the CRF. Pregnancy tests and equipment to perform vital signs can be 
delivered to the participants if on-site visits are not possible. The site is responsible for contracting a 
suitable courier and costs will be reimbursed by Novo Nordisk. Participants´ own home scales 
cannot be used for measuring body weight.  
If the assessments indicated in Table 10-7 cannot be performed as on-site visits, home-visits or 
remote visits (video, phone or similar), they should be performed at the first possible timepoint 
following the originally scheduled visit in agreement with Novo Nordisk. 
10.10.4 Study intervention 
Alternative dispensing methods of study intervention may be implemented, and details will be 
communicated and documented. The dispensing options will be provided by Novo Nordisk A/S and 
will be based on options and requirements at country level and if permitted by local regulations.

Minimum assessments following randomisation 
Please refer to Section 1.2 for the full flowchart. 
Procedures marked with a X should be prioritised and be performed on-site.  
Procedures marked with an X can be performed at the participant´s home, off-site, via the phone or video call if deemed necessary because of the lockdown. 
Procedures marked with a red X can subsequently be cancelled.

This SAP is based on the protocol: A 52-week study comparing the efficacy and safety of once 
weekly IcoSema and once weekly semaglutide, both treatment arms with or without oral 
anti-diabetic drugs, in participants with type 2 diabetes inadequately controlled with a GLP-1 
receptor agonist. COMBINE 2. This SAP include details on analysis of secondary estimands related 
to supportive secondary endpoints. There are no changes to the analyses described in the protocol, 
however additional information has been included in case of insufficient data for meaningful 
imputation of missing data for the primary analysis. The SAP also contains specification of 
additional derivations and analyses. 
1.1 
Objectives, Endpoints, and Estimands 
1.1.1 
Objectives 
1.1.1.1 
Primary objective 
To confirm superiority of once weekly IcoSema compared with once weekly semaglutide, both 
treatment arms with or without OADs, in terms of glycaemic control measured by change in HbA1c 
from baseline after 52 weeks in participants with T2D inadequately controlled a GLP-1 receptor 
agonist.  
1.1.1.2 
Secondary objectives 
To compare parameters of glycaemic control and safety of once weekly IcoSema with once weekly 
semaglutide, both treatment arms with or without OADs, in participants with T2D inadequately 
controlled with a GLP-1 receptor agonist.

General Considerations 
Baseline is defined as information collected at week 0 (V2). In case a measurement is not available 
at week 0 (V2) the most recent measurement prior to week 0 (V2) will be used as baseline. 
Presentation of results from a statistical analysis will include the estimated mean treatment 
difference (or ratio) presented together with the two-sided 95% confidence interval and the 
corresponding two-sided p-value. 
In the statistical models, explanatory factors will be coded as follows:  
 Randomised treatment: Once weekly IcoSema, Once weekly semaglutide  
 Region: Asia, Europe, North America, Other 
The regions will be defined as follows: 
 Asia: Japan, China, Taiwan 
 Europe: France, Greece, Slovakia, Switzerland, Sweden, Hungary 
 North America: United States, Canada

Primary Estimand Analysis 
4.2.1 
Definition of Endpoint 
The primary endpoint is change in HbA1c from baseline week 0 (V2) to week 52 (V54). 
4.2.2 
Main Analytical Approach 
The primary endpoint is change in HbA1c from baseline week 0 (V2) to week 52 (V54). 
The estimand (see Section 1.1.3.1), will be estimated based on the full analysis set using the in-
study data points set which includes all HbA1c measurements obtained at week 52 (V54) especially 
measurements from participants experiencing intercurrent events. The imputation approach for the 
primary estimand is a multiple imputation similar to the one described by McEvoy.1 
 Missing HbA1c measurements at week 52 (V54) for participants experiencing intercurrent 
events will be imputed from participants experiencing intercurrent events and have a 
measurement at week 52 (V54) in each treatment arm.

 Missing HbA1c measurements at week 52 (V54) for participants not experiencing intercurrent 
events are imputed from available measurements at week 52 (V54) from participants not 
experiencing intercurrent events in each treatment arm.  
The multiple imputation approach will be done the following way:  
 Imputation: An ANCOVA model for change in HbA1c from baseline week 0 (V2) to week 52 
(V54) for participants experiencing intercurrent events and have a measurement at week 52 
(V54) with randomised treatment as fixed factor, last available planned on-treatment HbA1c 
observation without initiation of non-randomised insulin treatment or additional anti-diabetic 
treatments for more than 2 weeks, the time point (study day) of last available planned on-
treatment HbA1c observation without initiation of non-randomised insulin treatment or 
additional anti-diabetic treatments for more than 2 weeks and baseline HbA1c as covariate. If 
participants not experiencing intercurrent events are missing measurements at week 52 (V54) an 
ANCOVA model will be defined in a similar way using available data from participants not 
experiencing intercurrent events. The estimated parameters, and their variances, from the 
imputation models will be used to impute missing HbA1c measurements at week 52 (V54). This 
will be done 1000 times and results in 1000 complete datasets.  
 For each of the complete data sets, the primary endpoint will be analysed using an ANCOVA 
model with region and randomised treatment as fixed factors, and baseline HbA1c as covariate. 
The estimates and standard deviations for the 1000 data sets will be pooled to one estimate and 
))&!*)*%(,!*!&%+)!%+!%5)(+#2 
 From the pooled estimate and standard deviation the 95% confidence interval for the treatment 
difference will be calculated. The corresponding two-sided p-value will also be calculated. 
This analysis has the underlying assumption that participants with missing data behave similarly as 
comparable participants within the same treatment arm i.e. that participants experiencing 
intercurrent events with missing data at week 52 (V54) behave like participants experiencing 
intercurrent events with data at week 52 (V54) within the same treatment arm and similar for 
participants not experiencing intercurrent events. 
In case the amount of data for the described imputation model is insufficient for meaningful 
imputation, the first alternative will be the following: 
1. Simplifying the imputation model by removing the following covariates from the imputation 
model: Last available planned on-treatment HbA1c observation without initiation of non-
randomised insulin treatment or additional anti-diabetic treatments for more than 2 weeks and 
the time point (study day) of last available planned on-treatment HbA1c observation without 
initiation of non-randomised insulin treatment or additional anti-diabetic treatments for more 
than 2 weeks. 
 
If the amount of data for this reduced model is still insufficient for meaningful imputation, the 
following imputation strategy will be applied instead: 
2. Missing values at week 52 (V54) will be imputed with baseline value adding a random error 
term. This imputation method also includes measurements collected after intercurrent events but 
is otherwise similar to the imputation method for endpoints where there is no data collection

Sensitivity Analysis 
The following sensitivity analysis will evaluate the robustness of the results towards the missing 
data assumption. 
For the primary endpoint, a two-dimensional tipping point analysis will be performed where 
participants having imputed HbA1c measurement at week 52 (V54) are assumed to have a worse 
outcome in the IcoSema arm and a better outcome in the semaglutide arm compared to what was

Supplementary Analysis 
The following supplementary analysis addressing a attributable estimand similar to the one 
described by Darken3 will be prepared. This estimand aims at estimating the effect of randomised 
treatment had all participants stayed on the randomised treatment for the entire 52 weeks treatment 
period. Intercurrent events that are considered adversely related to randomised treatment are 
considered attributable and are handled with a composite estimand strategy and a hypothetical 
estimand strategy is used for the remainder intercurrent events and data missing e.g. due to 
participants being lost to follow-up.  
The supplementary analysis will be done the following way: 
 Participants experiencing intercurrent events that are considered attributable are identified, 
see Appendix 3 (section 6.36.3) for split into attributable and none attributable intercurrent 
events. 
 Outcome after intercurrent events which are deemed attributable to randomised treatment 
are assigned the same unfavourable value in the following way: 
o A mixed-effect model for repeated measurements (MMRM) for change from 
baseline in HbA1c is fitted to data obtained before experiencing intercurrent events. 
The model include treatment, visit and interaction between treatment and visit as 
fixed effects, and subject as random effect. 
o The unfavourable value is assigned as the estimated change from baseline from the 
comparator arm at week 52 (V54) plus the standard deviation of the random 
intercept multiplied by the 90th percentile of the standard normal distribution. 
 The remaining missing data is imputed using a similar approach as for the primary analysis.

Supportive Secondary Efficacy Estimands 
The following subsections describe how the supportive secondary estimands related to supportive 
secondary efficacy endpoints (see section 1.1.3.2) will be estimated. The subsections refer to the 
corresponding supportive secondary endpoint. For calculation of endpoints please see appendix 2, 
section 6.2. 
4.3.1.1.1 
Change in body weight from baseline week 0 (V2) to week 52 (V54) 
The supportive secondary estimand regarding change in body weight from baseline week 0 (V2) to 
week 52 (V54) will be estimated using a model similar to the primary analysis above substituting 
body weight for HbA1c. 
4.3.1.1.2 
Change in fasting plasma glucose (FPG) from baseline week 0 (V2) to week 52 
(V54) 
The supportive secondary estimand regarding change in FPG from baseline week 0 (V2) to week 52 
(V54) will be estimated using a multiple imputation model as described below. 
Missing FPG values at week 52 (V54) (regardless of treatment completion status) for both treatment 
arms will be imputed with baseline value adding a random error term. The random error term is 
normally distributed with a standard deviation set equal to the estimated residual standard deviation 
of an ANCOVA analysis on the last available observation before experiencing intercurrent events. 
Specifically, the imputations and analyses will be carried out as follows: 
 First, an ANCOVA model with region and randomised treatment as fixed factors, and a baseline 
value as a covariate will be fitted to the last available observation before experiencing 
intercurrent events. 
 Second, the estimated residual standard deviation, s, from this model will be used to impute 
missing values by the baseline value, adding a random normally distributed term with mean 
zero and standard deviation s. This will be done 1000 times. 
 For each of the complete data sets, the endpoint will be analysed using an ANCOVA model 
with region and randomised treatment as fixed factors, and a baseline value as a covariate. The 
estimates and SDs for the 1000 data sets will be pooled to one estimate and associated SD using

 Number of clinically significant hypoglycaemic episodes (level 2) (<3.0 mmol/L [54 mg/dL],

 Number of severe hypoglycaemic episodes (level 3) from baseline week 0 (V2) to week 57 
(V56) 
 
For participants who discontinued randomised treatment, the number of episodes in the period 
where hypoglycaemic episodes are not collected (the period from time of follow-up 2 visit (V56) to 
planned end of the on-treatment data point set) will be imputed using a multiple imputation 
technique, assuming that the episode rate pre-follow-up 2 (V56) follows the respective treatment 
arms rate whilst post-follow-up 2 (V56) episode rate is the rate of the comparator arm. The 
imputation will be done as follows:  
 First, a Bayes negative binomial model with log-link function is fitted to the number of episodes 
data for participants in the comparator arm to obtain the posterior distribution of model 
parameters. The model will include region as fixed factor and the logarithm of the time period 
in which a participant is considered exposed to randomised treatment as offset. 
 Second, based on the estimated parameters for the comparator arm in this model, the number of 
episodes in the missing period will be imputed for participants having discontinued randomised 
treatment. One thousand (1000) complete dataset are generated by sampling from the estimated 
distribution. 
 For each of the complete datasets, the number of episodes will be analysed using a negative 
binomial model with log-link function, treatment and region fixed factors and offset as 
described in step 1 plus the missing period for which the number of episodes have been 
imputed. The estimates and standard errors for the 1000 data sets will be pooled to one estimate

4.6.2 
Pharmacokinetic modelling 
Insulin icodec serum concentration data and semaglutide plasma concentration data will be used for 
population PK analysis. The objective of the population PK analysis is to evaluate the effects of 
relevant covariates on insulin icodec and semaglutide exposure. 
The population PK analysis will be performed by Quantitative Clinical Pharmacology, Novo 
Nordisk. A more technical and detailed elaboration of the population PK analysis will be given in a 
modelling analysis plan, which will be prepared before database lock. In brief, previously 
developed PK models for insulin icodec and semaglutide will be applied. The absorption rate 
constants in the models will be fixed, and the apparent clearance and volume of distribution 
parameters will be re-estimated. The covariates of interest will be incorporated into the PK models 
using criteria which will be specified in the modelling analysis plan. 
The population PK analysis will be reported in a separate modelling report, which will not be part 
of the clinical study report. The individual insulin icodec serum concentration data and the 
individual semaglutide plasma concentration data will be tabulated in the bioanalytical report.

Interim Analysis 
Not applicable for this study.

Changes to Protocol-planned Analysis 
There are no changes to the protocol-planned analysis.

Partial database lock 
A partial database lock may be performed at the end of the treatment period for all participants, i.e. 
after the date of the last participant last treatment visit. The database will be updated after the partial 
database lock to include remaining safety information. The full database lock will be performed 
after the date of the last participant last visit. 
The analysis of the primary endpoint and all other efficacy endpoints will be performed based on 
the data from the partial database lock. Analysis of safety data will be performed after the full 
database lock. This approach is implemented to allow earlier availability of IcoSema to a T2D 
patient population in need of treatment intensification expected to benefit from an insulin and 
GLP-1 combination product. A detailed plan for data handling and operational aspects of the partial 
database lock and the database update will be finalised before the partial database lock.
