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 Union1, because 
it neither significantly impacts the safety nor physical/mental integrity of subjects nor the scientific 
value of the trial. 
Overall rationale for preparing protocol, version 3.0: 
The protocol has been amended to correct typos and exclude Japan and Germany from 
co-participation in clinical trials evaluating medicinal products for prevention or treatment of 
COVID-19 disease or postinfectious conditions as per local health authority request.

Protocol summary 
1.1 
Synopsis 
Rationale: 
Insulin icodec is a novel long-acting insulin analogue which is developed to safely cover the basal 
insulin requirements for a full week with a single subcutaneous injection. The present trial is a 26-
week trial designed to investigate effect and safety of once weekly insulin icodec in comparison to 
once daily insulin degludec, both with or without non-insulin anti-diabetic drugs, in basal insulin 
treated subjects with type 2 diabetes (T2D). 
Objectives and endpoints: 
Primary objective 
The objective of this trial is to demonstrate the effect on glycaemic control of once weekly insulin 
icodec, with or without non-insulin anti-diabetic drugs, in subjects with T2D treated with basal 
insulin. This includes comparing the difference in change from baseline in HbA1c between insulin 
icodec and insulin degludec after 26 weeks of treatment to a non-inferiority limit of 0.3%. 
Estimand 
The estimand is the ‘treatment policy estimand’ defined as the treatment difference between insulin 
icodec and insulin degludec of the change in HbA1c from baseline to week 26 for all randomised 
subjects, irrespective of adherence to randomised treatment and changes to anti-diabetic background 
medication. The following intercurrent events will be handled by the treatment policy strategy: 
initiation of bolus insulin treatment for more than 2 weeks, discontinuation of randomised insulin 
treatment, and withdrawal from the trial (measurements collected after these intercurrent events are 
used in the primary analysis).

Overall design: 
This is a 26-week randomised, open label, active-controlled, parallel-group, multicentre, 
multinational, treat-to-target trial with two treatment arms.  
Subjects will be randomised (1:1) to receive once weekly insulin icodec or once daily insulin 
degludec.

Key inclusion criteria: 
1. Male or female aged above or equal to 18 years at the time of signing informed consent. 
2. Diagnosed with T2D ≥ 180 days prior to the day of screening. 
3. HbA1c from 7.0-10.0% (53.0-85.8 mmol/mol) both inclusive at screening confirmed by central 
laboratory analysis. 
4. Treated with once daily or twice daily basal insulin (Neutral Protamine Hagedorn insulin, 
insulin degludec, insulin detemir, insulin glargine 100 units/mL, or insulin glargine 300 
units/mL): ≥ 90 days prior to the day of screening with or without any of the following anti-
diabetic drugs/regimens with stable doses ≥ 90 days prior to screening: 
• Metformin 
• Sulfonylureas 
• Meglitinides (glinides) 
• DPP-4 inhibitors 
• SGLT2 inhibitors 
• Thiazolidinediones 
• Alpha-glucosidase inhibitors 
• Oral combination products (for the allowed individual oral anti-diabetic 
drugs) 
• Oral or injectable GLP-1-receptor agonists 
5. Body mass index (BMI) ≤ 40.0 kg/m2. 
Key exclusion criteria: 
1. Any episodesa of diabetic ketoacidosis within 90 days prior to the day of screening. 
2. Myocardial infarction, stroke, hospitalisation for unstable angina pectoris or transient ischaemic 
attack within 180 days prior to the day of screening. 
3. Chronic heart failure classified as being in New York Heart Association Class IV at screening. 
4. Anticipated initiation or change in concomitant medications (for more than 14 consecutive days) 
known to affect weight or glucose metabolism (e.g. treatment with orlistat, thyroid hormones, or 
corticosteroids). 
5. Uncontrolled and potentially unstable diabetic retinopathy or maculopathy. Verified by a fundus 
examination performed within the past 90 days prior to screening or in the period between 
screening and randomisation. Pharmacological pupil-dilation is a requirement unless using a 
digital fundus photography camera specified for non-dilated examination. 
a as declared by the subject or in the medical records.  
Number of subjects: 
Approximately 693 subjects will be screened to achieve 520 subjects randomly assigned to trial 
product.

Introduction 
Diabetes mellitus is a metabolic disorder characterised by the presence of hyperglycaemia due to 
defective insulin secretion, insulin action or both. The chronic hyperglycaemia of diabetes mellitus 
is associated with significant long-term complications, particularly damage, dysfunction and failure 
of various tissues – especially the kidney, eye, nerves, heart and blood vessels.2 Diabetes is 
generally classified according to aetiological factors, where type 1 diabetes (T1D) and type 2 
diabetes (T2D) constitute the vast majority of cases. In the latest edition of the International 
Diabetes Federation’s Diabetes Atlas (2019), the estimated worldwide diabetes prevalence was 463 
million, with a prediction that by 2045, the number of people with diabetes will have increased to 
700 million.3  
Insulin icodec (proposed INN) is a novel long-acting insulin analogue which is developed to safely 
cover the basal insulin requirements for a full week with a single subcutaneous injection. Insulin 
icodec has a terminal elimination half-life of approximately 196 hours. For subjects with diabetes 
there is still an unmet medical need for products with the potential to improve clinical outcomes 
through reduced treatment burden and increased treatment adherence and persistence4 compared to 
once or twice daily basal insulin administration. The aim of the development programme for insulin 
icodec is to improve clinical outcomes for subjects with diabetes by limiting the burden associated 
with insulin treatment. 
2.1 
Trial rationale 
The present trial is a 26-week trial designed to investigate effect and safety of once weekly insulin 
icodec in comparison to once daily insulin degludec 100 units/mL (referred to as insulin degludec in 
this document), both with or without non-insulin anti-diabetic drugs, in basal insulin treated 
subjects with T2D.  
The long-acting basal insulin products currently approved for treatment of diabetes are administered 
once or twice daily. Development of sustained release formulations or compounds with prolonged 
action has in several treatment areas been demonstrated to improve subject compliance and 
treatment outcomes. The once weekly treatment regimen for insulin icodec is expected to represent 
a more convenient basal insulin, with significantly fewer injections over time, which could improve 
treatment adherence4 as compared to once daily or twice daily basal insulin for subjects with T2D. 
Overall, the results of the present trial will be important for evaluating the effect and safety of 
insulin icodec in insulin experienced subjects with T2D and will be used to support the marketing 
authorisation approval of insulin icodec. The trial will also generate data for guidance on transfer 
from once or twice daily basal insulin to once weekly insulin icodec, data on dosing flexibility, 
treatment satisfaction, and insulin preference.

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.5 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.6 
The current treatment cascade follows a stepwise approach comprising lifestyle changes in 
combination with pharmacological intervention. In many countries, metformin is recommended as 
initial pharmacological therapy, followed by combination therapy with other oral anti-diabetic 
drugs, glucagon-like peptide 1 receptor agonists (GLP-1 RA) and/or insulin as the disease 
progresses.7 On average, after failure of diet and exercise alone, subjects require a new intervention 
with glucose-lowering agents every 3-4 years in order to obtain/retain good glycaemic control.8 
Clinical inertia, often resulting from a resistance to insulin initiation and intensification, is a major 
contributing factor to subjects with T2D who are not achieving recommended glycaemic targets.9, 10 
Increased convenience is believed to support timely insulin initiation in the treatment for T2D and 
thereby overcoming the clinical inertia associated with insulin initiation. 
Insulin icodec  
Insulin icodec is a novel long-acting insulin analogue which is developed to safely cover the basal 
insulin requirements for a full week with a single subcutaneous injection. Insulin icodec has a 
terminal elimination half-life of approximately 196 hours. The molecule consists of a peptide 
backbone and a fatty acid-containing side-chain. The peptide backbone is more resistant towards 
proteolytical degradation compared to human insulin and the side chain gives a strong binding to 
albumin. Both features contribute to the long action of insulin icodec.  
The development programme for insulin icodec is currently ongoing. Three clinical pharmacology 
trials, NN1436-4314 [T2D], NN1436-4226 [renal impaired] and NN1436-4422 [T1D] have been 
completed. No unexpected safety concerns were identified. Two clinical pharmacology trials 
(NN1436-4462 [T2D] and NN1436-4225 [T1D]) are ongoing. 
Three phase 2 trials in subjects with T2D have recently been completed (NN1436-4465, NN1436-
4383 and NN1436-4466). Once weekly insulin icodec was shown to provide comparable glucose 
lowering effects and similar safety profile to insulin glargine in subjects with T2D. Results from 
these trials were used in the development of the insulin icodec titration guideline, see Appendix 8 
(Section 10.8). 
A comprehensive review of results from the non-clinical and clinical studies of insulin icodec can 
be found in the current edition of the investigator’s brochure11 and any updates hereof.

Summary of data/ 
rationale for risk 
Mitigation strategy 
Trial treatment: insulin icodec 
Identified risk:  
Hypoglycemia  
Hypoglycemia is an 
anticipated undesirable 
effect related to the 
pharmacological 
mechanism of insulin. 
Exclusion criteria in clinical trials with subjects at 
increased risk of hypoglycaemia: 
• Known hypoglycaemic unawareness as indicated 
by the investigator according to Clarke’s 
questionnaire question 8 (Section 5.2), 
• Recurrent severe hypoglycaemic episodes within 
the last year as judged by the investigator. 
Frequent blood glucose measurements will be made 
throughout drug exposure and will prevent worsening 
of hypoglycaemia by early detection and 
administration of carbohydrates and medical treatment, 
if necessary. 
The risk of hypoglycaemia is addressed in the SI-IC 
and IB11. Subjects are provided with a guidance on 
hypoglycaemia awareness and rescue actions. 
Identified risk:  
Injection site reactions 
Injection site reactions 
may occur with all 
injectable drugs. Injection 
site reactions were 
reported in trials NN1436-
4422, NN1436-4383, 
NN1436-4465, NN1436-
4466, NN1436-4226. All 
were mild and resolved 
during continued treatment 
with insulin icodec. 
Subjects are instructed by the investigators on the most 
appropriate injection techniques.  
Recommendations on rotation of the site of injection 
are included in the trial protocol and SI-IC.  
Investigators and subjects will be instructed to monitor 
for injection site reactions at the place of injection for 
early detection. Investigators should ensure careful 
monitoring and medical evaluation in case of injection 
site reaction occurrence. The risk of injection site 
reactions is described in the IB11 and the SI-IC. 
For further information on injection site reactions, 
please refer to Appendix 3 (Section 10.3.3). 
Potential risk: 
Hypersensitivity  
Severe systemic 
hypersensitivity reactions 
may potentially occur 
following injection of 
therapeutic proteins. No 
systemic hypersensitivity 
reactions were observed in 
trials NN1436-4314, 
NN1436-4383, NN1436-
4465, NN1436-4466, 
NN1436-4226 and 
NN1436-4422.  
Known or suspected hypersensitivity to trial product(s) 
or related products is an exclusion criterion in the 
clinical trial.  
Subjects and investigators will be instructed in signs 
and symptoms of hypersensitivity reactions and 
subjects will be instructed to contact the site 
immediately in case of signs of systemic 
hypersensitivity. 
Blood sampling for assessment of antibodies against 
insulin icodec, as well as other assessments will be 
conducted in the case of systemic hypersensitivity 
reaction. Confirmed anti-insulin icodec antibody 
positive samples will have an antibody titer value 
determined and will be further tested for cross-
reactivity to endogenous insulin. 
The risk of hypersensitivity reactions is described in 
the IB11 and SI-IC.   
For further information on hypersensitivity reactions, 
please refer to Section 8.9.2 and Appendix 3 (Section 
10.3.3).

Potential risks:  
Antibody formation leading 
to changes in clinical effect 
Antibodies to exogenously 
delivered insulin are 
common with insulin 
treatment but are not often 
clinically significant. 
In NN1436-4383 clinical 
trial, the proportion of 
subjects with anti-insulin 
antibodies was higher with 
insulin icodec (82.1%) 
than insulin glargine 
(35.0%). 
Maximum level of 
antibody response was 
higher against insulin 
icodec than insulin 
glargine.  
No apparent relationship 
between antibody titres 
and change in HbA1c or 
weekly insulin dose was 
observed.   
Blood samples will be taken for analysis of serum 
antibodies against insulin icodec at pre-first dose time 
point. Then at appropriate time points during the trial 
and at the end of trial visit. Confirmed anti-insulin 
icodec antibody positive samples will have an antibody 
titer value determined and will be further tested for 
cross-reactivity to endogenous insulin. There will be a 
close monitoring of the glycemic control on subject 
level during the trial. In case lack of clinical effect is 
observed, rescue medication will be provided if 
deemed necessary. 
In the case of systemic hypersensitivity reaction blood 
sampling for assessment of antibodies against insulin 
icodec, as well as other assessments will be conducted. 
For more information, please refer to Section 8.9.2 and 
Appendix 3 (Section 10.3.3). 
Trial procedures 
Potential risk:  
COVID-19 infection in 
relation to participation in 
trial 
Subjects 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 area. To minimize the risk 
as much as possible, the following measures have been 
taken: 
• 
Cautious subject recruitment planning ensures 
controlled subject 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. 
• 
On-site visits will be well-prepared and as short as 
possible. Physical contact between subjects and 
site staff will be limited to the extent possible, and 
protective measures will be implemented (e.g. use 
of masks, sanitizers, no aerosol-generating 
procedures etc. according to the local practice). 
• 
A COVID-19 mitigation plan has been developed 
for this trial which lists the additional actions to 
consider in case a site or country are locked down 
and subjects cannot attend on-site visits.

2.3.2 
Benefit assessment 
Insulin icodec is currently in development for treatment of diabetes mellitus. In both clinical and 
non-clinical trials, insulin icodec has shown to have a long and stable PK and PD profile, supporting 
a once weekly treatment. Currently available long-acting basal insulin products need to be 
administered once daily to provide 24-hour coverage. Market research has shown that people with 
diabetes, put value in reducing the number of insulin injections15. Therefore, the treatment 
adherence and quality of life are expected to increase by introducing a once weekly basal insulin 
treatment. 
The trial population will consist of basal insulin treated subjects with T2D. For all subjects 
participating in this 26-week trial, the anticipated benefits include improved glycaemic control. The 
titration algorithm in Appendix 8 (Section 10.8), which specifies recommended adjustments of 
basal insulin dose at different plasma glucose levels, will be used to ensure that subjects receive 
optimal treatment. Subjects will receive intense medical care by means of contact with the sites 
weekly. 
2.3.3 
Overall benefit-risk conclusion 
Insulin icodec is efficacious at clinically relevant doses. Titration guidance for phase 3a trials aims 
to achieve good glycaemic control without increasing the risk of hypoglycaemic events.  
No new significant safety information that changes the current benefit–risk profile of insulin icodec 
emerged from the ongoing and completed clinical trials. The safety profile of insulin icodec remains 
in line with the cumulative experience. 
As an overall assessment, Novo Nordisk evaluates that the benefit–risk balance of insulin icodec 
remains favourable.  
Considering the measures taken to minimise risk to subjects participating in this trial, the potential 
risks identified in association with insulin icodec are justified by the anticipated benefits that may 
be afforded to subjects with diabetes mellitus.

Objectives and endpoints 
3.1 
Primary, secondary and exploratory objective and estimand 
3.1.1 
Primary objective 
To demonstrate the effect on glycaemic control of once weekly insulin icodec, with or without non-
insulin anti-diabetic drugs, in subjects with T2D treated with basal insulin. This includes comparing 
the difference in change from baseline in HbA1c between insulin icodec and insulin degludec after 
26 weeks of treatment to a non-inferiority limit of 0.3%. 
3.1.2 
Secondary objective 
To compare safety and patient reported outcomes with once weekly insulin icodec versus once daily 
insulin degludec, both with or without non-insulin anti-diabetic drugs, in subjects with T2D treated 
with basal insulin. 
3.1.3 
Estimand 
The estimand is the ‘treatment policy estimand’ defined as the treatment difference between insulin 
icodec and insulin degludec of the change in HbA1c from baseline to week 26 for all randomised 
subjects, irrespective of adherence to randomised treatment and changes to anti-diabetic background 
medication. The following intercurrent events will be handled by the treatment policy strategy: 
initiation of bolus insulin treatment for more than 2 weeks, discontinuation of randomised insulin 
treatment, and withdrawal from the trial (measurements collected after these intercurrent events are 
used in the primary analysis).

Trial design 
4.1 
Overall design 
This is a 26-week randomised, open label, active-controlled, parallel-group, multicentre, 
multinational, treat-to-target trial with two treatment arms. The trial investigates the effect on 
glycaemic control, safety and electronic patient reported outcomes (PROs) of treatment with once 
weekly insulin icodec compared to once daily insulin degludec, both with or without non-insulin 
anti-diabetic drugs, in basal insulin treated subjects with inadequately controlled T2D on once or 
twice daily insulin. 
The trial duration is approximately 33 weeks, consisting of a 2-week screening period, followed by 
a 26-week randomised treatment period and a 5-week follow-up period. The overall trial design and 
visit schedule are outlined in Figure 4-1 and trial flowchart (Section 1.2), respectively. 
 
Figure 4-1 
Trial design 
Subjects will be randomised (1:1) to receive once weekly insulin icodec or once daily insulin 
degludec. The dose and dosing frequency of any pre-trial non-insulin anti-diabetic treatment should 
not be changed during the trial unless due to safety concerns; except for treatment with 
sulfonylureas and glinides that must be discontinued at randomisation. During the 26-week

treatment period, subjects will have contact with the site weekly either at site visits or by phone. 
The end of treatment visit (V28) will be one week after the last dose of insulin icodec and on the 
day of or the day after the last dose of insulin degludec. Two follow-up visits (V29 and V30) will be 
performed 2 and 5 weeks, respectively, after the end of treatment visit. This will allow for 
appropriate wash-out of trial drug, following at least 5 half-lives of insulin icodec. After the end of 
treatment subjects will be transferred to a marketed product at the discretion of the investigator. 
To evaluate the effect on glycaemic control, subjects will have continuous glucose monitoring 
(CGM) profiles collected, as specified in the flowchart (Section 1.2). The CGM data will be blinded 
for both subjects and investigators. 
Event adjudication will be performed for acute coronary syndrome events (acute myocardial 
infarction or unstable angina pectoris requiring hospitalisation), cerebrovascular events (stroke or 
transient ischemic attack), heart failure (requiring hospitalisation or urgent heart failure visit) and 
all-cause death. 
4.2 
Scientific rationale for trial design 
The trial is designed to investigate the effect on glycaemic control, safety and PROs of once weekly 
insulin icodec versus once daily insulin degludec during 26 weeks of treatment. 
Currently, basal insulins are dosed once or twice daily. In order to compare to well established and 
widely used basal insulin analogues with once daily dosing, insulin degludec has been chosen as 
comparator. 
The treatment arms will be open label as it was not considered feasible to blind the two treatments 
due to assessment of treatment satisfaction and preference. Patient reported outcome questionnaires 
are used in the trial to investigate the subjects’ experience of the impact on treatment burden. The 
treatment burden is expected to be reflected in treatment satisfaction and patient preference. 
The treatment duration of 26 weeks is evaluated to be adequate time for assessing effect on 
glycaemic control and safety. This duration will also allow for up-titrating the basal insulin. The 
treat-to-target approach has been chosen in order to ensure optimal titration of insulin based on self-
measured plasma glucose (SMPG) values with the aim of improving HbA1c in the period. 
Titration of insulin icodec and insulin degludec will be based on pre-breakfast SMPG values and 
follow the principles outlined in the titration guideline, see Appendix 8 (Section 10.8). CGM values 
will be used during the reporting phase to generate profiles for evaluating the effect on glycaemic 
control during initiation of trial product, steady state and follow-up. To avoid influence on titration 
and the glycaemic control, the CGM data will be blinded for both study subjects and investigator. 
Subjects included in the trial will already be on basal insulin analogue treatment with or without 
non-insulin anti-diabetic drugs ensuring a trial population representative of a broad T2D population.

To minimise the risk of hypoglycaemia sulfonylureas and glinides must be discontinued at 
randomisation. 
To safeguard subjects, the inclusion and exclusion criteria defined in this trial will limit the trial 
population to subjects not suffering from advanced underlying diseases other than T2D and related 
diseases. This is to avoid compromising the safety of the subjects participating in the trial and to 
strengthen conclusions regarding the effect and safety of once weekly insulin icodec. 
The end of trial visit is planned six weeks after the last weekly dose of insulin icodec, allowing 
enough time for wash-out of trial drug, following at least five half-lives of insulin icodec. 
A sufficient assay-sensitivity for the non-inferiority evaluation will be ensured by the treat-to-target 
trial design, the applied titration target/algorithm together with close titration surveillance and by 
having focus on adherence and discontinuation.

Subject input into design 
Not applicable for this trial. 
4.3 
Justification for dose 
Insulin degludec will be switched from the pre-trial basal insulin analogues according to local label 
and insulin icodec will be initiated according to the principles outlined in the titration guideline in 
Appendix 8 (Section 10.8). A 50% loading dose will be applied to avoid glycaemic slip during the 
first few weeks of treatment. No safety concerns have been identified in subjects with T2D, 
including vulnerable subjects, using a loading dose when initiating insulin icodec (trial NN1436-
4466). 
One unit of insulin icodec has similar glucose lowering effect to one unit of insulin degludec, and 
therefore once weekly dosing corresponds to seven times the daily dose of the once daily 
comparator.  
The PK/PD properties of insulin icodec following five weeks of once weekly dosing in subjects 
with T2D (trial NN1436-4314) showed that insulin icodec exposure was well distributed across the 
dosing interval, with a PK profile suitable for once weekly dosing. Insulin icodec was well tolerated 
in subjects with T2D and no unexpected safety concerns were identified after multiple once weekly 
dosing in the dose range of 12−24 nmol/kg (2-4 units/kg). 
After randomisation, subjects should start once daily insulin degludec or once weekly insulin icodec 
injections on the same day. Due to the longer half-life of insulin icodec, the last dose of insulin 
icodec will be administered 25 weeks after randomisation, while the last dose of once daily insulin 
degludec will be administered 26 weeks after randomisation. The follow-up period for both insulin 
icodec and insulin degludec will be the 5 weeks from end of treatment (V28) until end of trial 
(V30).

Preparation/handling/storage/accountability 
Only subjects randomised to treatment may use trial product and only delegated site staff may 
supply trial product. 
• 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 material manual and trial product 
label. 
• Each site will be supplied with sufficient trial product for the trial on an ongoing basis. Trial 
product will be distributed to the sites according to screening and randomisation. 
• The investigator or designee must confirm that appropriate temperature conditions have been 
maintained during transit for all trial products received, and that any discrepancies are reported 
and resolved before use of the trial products. 
• All trial products must be stored in a secure, controlled, and monitored (manual or automated) 
area in accordance with the labelled storage conditions with access limited to the investigator 
and delegated site staff. 
• The investigator must inform Novo Nordisk immediately if any trial product has been stored 
outside specified conditions. The trial product must not be dispensed to any subject before it 
has been evaluated and approved for further use by Novo Nordisk. Additional details 
regarding handling of temperature deviations can be found in the trial material manual. 
• The investigator or designee is responsible for drug accountability and record maintenance (i.e. 
receipt, accountability and final disposition records). 
• The investigator or designee must instruct the subject in what to return at next visit. 
• Each single pen should be accounted. 
• 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, un-used, expired or damaged trial products (for technical complaint samples, see 
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. 
6.3 
Measures to minimise bias: Randomisation and blinding 
• This is an open label trial; however, the specific treatment for a subject will be assigned using 
an IWRS. The site will access the IWRS before the start of trial product administration for 
each subject. Potential bias will be reduced by central randomisation and adjudication. 
• All subjects will be centrally screened and randomised using an IWRS and assigned to the next 
available treatment according to randomisation schedule. Trial product will be 
dispensed/allocated at the trial visits summarised in the flowchart (Section 1.2).

Treatment compliance 
Drug treatment compliance 
Throughout the trial, the investigator will remind the subjects to follow the trial procedures and 
requirements to encourage subject compliance. 
When subjects self-administer trial product at home, compliance with trial product administration 
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, insulin dose and hypoglycaemia reporting 
• Evaluating glycaemic control and adherence to the visit schedule 
• If any suspicion of non-compliance arises the site must enter into a dialogue with the subject, 
re-emphasizing the importance of compliance and uncover barriers to compliance. This 
dialogue must be documented in the medical record.  
6.5 
Concomitant medication 
Any medication other than the trial product and anti-diabetic medication that the subject receives 
from screening (V1) until end of trial visit (V30) must be recorded along with: 
• Generic name or trade name  
• Indication  
• Dates of administration including start and stop date. 
Concomitant medication (diabetes) 
Any anti-diabetic medication other than the trial product that the subject receives from screening 
(V1) until end of trial visit (V30) must be recorded in a separate concomitant medication (diabetes) 
form in the electronic case report form (eCRF).  
The following information must be recorded for oral anti-diabetic drugs, GLP-1 RAs, insulin 
products including pre-trial insulin and post-treatment insulin in the follow-up period: 
• Generic name or trade name (for insulin products: only trade name). 
• Dates of administration including start and stop date. 
• Doses and frequency (e.g. once daily, twice daily). 
Until end of treatment (V28) only randomised treatment (trial products and pre-trial non-insulin 
anti-diabetic background medication except for sulfonylureas and glinides which must be 
discontinued at randomisation) are allowed, unless due to safety reasons at the discretion of the 
investigator. If the investigator chooses to initiate anti-diabetic medication or change dose of pre-
trial anti-diabetic background medication prior to end of treatment (V28), this should be registered 
in the eCRF as change in concomitant medication (diabetes).

Not applicable for this trial. 
6.7 
Treatment after end of trial 
When discontinuing trial products, the subject should be transferred to a suitable marketed product 
at the discretion of the investigator. If the switch to post-trial treatment includes a new insulin 
treatment, please refer to the titration guideline in Appendix 8 (Section 10.8).  
7 
Discontinuation of trial treatment and subject 
discontinuation/withdrawal 
Treatment of a subject may be discontinued at any time during the trial at the discretion of the 
investigator for safety, behavioural, compliance or administrative reasons. 
Efforts must be made to have the subjects who discontinue trial product attend the end of treatment 
visit (V28) as soon as possible to collect the required data for the analysis of the primary endpoint. 
Two follow-up visits, V29 and V30, must be performed after discontinuation of the trial product. 
Visits V29 and V30 must be conducted 3 and 6 weeks respectively after discontinuation of once 
weekly insulin icodec and 2 and 5 weeks respectively after discontinuation of once daily insulin 
degludec. It is stressed that the visit window is plus 3 days for both visits V29 and V30. 
Further, it is important that discontinued subjects come in for discontinuation follow-up visit V28A, 
26 weeks after the randomisation visit. V28A will be the last visit for discontinued subjects. 
Subjects who prematurely discontinue trial product should keep and use the eDiary, and return it at 
the follow-up visit 2 (V30).

The investigator should change subject status in the HCP web portal to 'Follow-up' at the end of 
treatment visit to ensure that the subject should no longer report insulin dose. 
Continue to collect, record and report AEs as described in Section 8.3. AEs and anti-diabetic 
medication should be collected and recorded in the eCRF until the discontinuation follow-up visit 
(V28A) for discontinued subjects, no other concomitant medication will be collected. Please, refer 
to Section 6.7 for treatment after end of trial. 
In case of any uncertainty regarding the scheduling of the visits after discontinuation or questions to 
said visits, the investigator should consult Novo Nordisk for further guidance. 
Only subjects who withdraw consent will be considered as withdrawn from the trial. Subjects must 
be educated about the continued scientific importance of their data, even if they discontinue trial 
product. Further, the site should stay in contact with discontinued subjects by phone and/or site 
visits to motivate subjects to attend the visits until the discontinuation follow-up visit (V28A). Site 
contact with discontinued subjects should be documented in the medical record. 
7.1 
Discontinuation of trial treatment 
The trial product must be discontinued, if any of the following applies for the subject: 
1. Safety concern related to trial product 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 triala 
5. Lack of efficacy, defined as fulfilment of ALL 4 criteria below: 
a. No reduction in HbA1c measured by central laboratory from randomisation (V2) to 
V12, or to V20, AND 
b. The pre-breakfast SMPG readings on 3 consecutive days higher than 240 mg/dL 
(13.3 mmol/L) within the last two weeks period despite appropriate dose adjustments 
AND  
c. A confirmatory fasting plasma glucose exceeding 240 mg/dL (13.3 mmol/L) 
measured by central laboratory. The subject should come in for an unscheduled visit

d. No treatable intercurrent cause (e.g. non-compliance) for the hyperglycaemia at the 
investigator’s judgment. 
a Simultaneous participation in a trial with the primary objective of evaluating an approved or non-approved 
investigational medicinal product for prevention or treatment of COVID-19 disease or postinfectious conditions is 
allowed at the investigator discretion without discontinuing trial product. 
The primary reason for discontinuation of trial product must be specified in the end-of-treatment-
form in the eCRF, and final drug accountability must be performed. A treatment status session must 
be made in the IWRS. 
A subject, who does not fulfil the eligibility (inclusion/exclusion) criteria, must not be randomised. 
Randomisation in violation of any of the eligibility criteria is good clinical practice (GCP) non-
compliance and must be reported to the sponsor without delay. This will be handled as an important 
protocol deviation, and the independent ethics committee/institutional review board (IEC/IRB) and 
regulatory authorities must be notified according to local requirements.  
Subjects that are randomised in violation of inclusion and exclusion criteria can be allowed to 
continue in the trial and receive trial product if there are no safety concerns as evaluated by the 
investigator and Novo Nordisk medical specialist. 
7.1.1 
Temporary discontinuation of trial treatment 
The subject should adhere to the treatment to the extent possible, with the exception of any adverse 
events such as hospitalisation or safety concerns, at the discretion of the investigator. Subjects who 
have temporarily discontinued trial product are allowed to restart trial product, unless any of the 
discontinuation criteria specified in Section 7.1 applies.

Rescue criteria 
Not applicable for this trial. 
7.2 
Subject discontinuation/withdrawal from the trial 
A subject may withdraw consent at any time at his/her own request. If a subject withdraws consent, 
the investigator must ask the subject if he/she is willing, as soon as possible, to have assessment 
performed according to the end of treatment visit (V28). See the flowchart (Section 1.2) for data to 
be collected. 
Final drug accountability must be performed even if the subject is not able to come to the site. A 
treatment status session must be made in the IWRS.

If the subject withdraws consent, Novo Nordisk may retain and continue to use any data collected 
before such a withdrawal of consent. 
If a subject withdraws from the trial, he/she may request destruction of any samples taken and not 
tested, and the investigator must document this in the medical record. 
Although a subject is not obliged to give his/her reason(s) for withdrawing, the investigator must 
make a reasonable effort to ascertain the reason(s), while fully respecting the subject's rights. Where 
the reasons are obtained, the primary reason for withdrawal must be specified in the end of trial 
form in the eCRF. 
7.2.1 
Replacement of subjects 
Subjects who discontinue trial product or withdraw from trial will not be replaced. 
7.3 
Lost to follow-up 
A subject 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 subject fails to return to the site for a required visit: 
• The site must attempt to contact the subject and reschedule the missed visit as soon as possible 
and counsel the subject on the importance of maintaining the assigned visit schedule and 
ascertain whether or not the subject wishes to and/or should continue in the trial. 
• Before a subject is deemed lost to follow-up, the investigator or designee must make every 
effort to regain contact with the subject (where possible, at least three telephone calls and, if 
necessary, a certified letter to the subject's last known mailing address or local equivalent 
methods). These contact attempts should be documented in the subject's source document. 
• Should the subject continue to be unreachable, he/she will be considered to have withdrawn 
from the trial with a primary reason of `lost to follow-up'. 
8 
Trial assessments and procedures 
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 trial related activity, see 
Appendix 1 (Section 10.1.3). 
• All screening evaluations must be completed and reviewed to confirm that potential subjects 
meet all inclusion criteria and none of the exclusion criteria. 
• The investigator will maintain a screening log to record details of all subjects screened and to 
confirm eligibility or record reason for screen failure, as applicable. 
• At screening, subjects will be provided with a card stating that they are participating in a trial 
and giving contact details of relevant site staff that can be contacted in case of emergency.

• Adherence to the trial design requirements, including those specified in the flowchart, is 
essential and required for trial conduct.  
• Assessments should be carried out according to the clinic’s standard of practice unless specified 
in 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: 
o Blood sample collection  
o Other assessments to confirm eligibility 
o Randomisation in IWRS 
o Continuous glucose monitoring fitting and training 
o The investigator should create a subject profile and record administrative 
information (e.g. subject ID, year of birth and gender and treatment arm in the HCP 
web portal  
o Subjects should be provided with an eDiary and instructed in how to use it.  
o The BG meter should be connected with the eDiary  
o A fasting SMPG should be measured using the BG meter 
o Dosing of trial product 
• 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 subjects through the HCP web portal, before or during each visit/phone contact. 
• Review of eDiary, ECG, laboratory reports, eye- and physical examinations must be 
documented either on the documents or in the subject's source documents. If clarification of 
entries or discrepancies in the eDiary is needed, the subject must be questioned, and a 
conclusion made in the subject's source documents, the eDiary should be updated 
retrospectively if applicable. Care must be taken not to bias the subject. 
• Source data of clinical assessments performed and recorded in the eCRF must be available and 
will usually be in the subject’s medical records. Additional recording to be considered source 
data includes, but is not limited to; laboratory reports, BG meter, CGM, pictures and ECG 
recordings.  
• The investigator should ensure that the electronic patient reported outcome questionnaires are 
completed by the subject in the eDiary. 
• Repeat samples may be taken for technical issues and unscheduled samples or assessments may 
be taken for safety reasons. Please refer to Appendix 2 (Section 10.2) for further details on 
laboratory samples.

8.1.1 
Self-measured plasma glucose (SMPG) 
Subjects will be provided with a blood glucose 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 plasma glucose measurements 
required in the protocol, as described in the flowchart (Section 1.2). 
A baseline SMPG value, in fasting condition, should be collected using the BG meter at V2.  
Pre-breakfast daily SMPG  
Subjects should be instructed to measure their pre-breakfast SMPG daily from week 0 (V2) to end 
of trial (V30) 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 
trial for central titration surveillance, to ensure compliance with the titration guideline in 
Appendix 8 (Section 10.8) and will not be reported in the clinical trial report. All data will be stored 
by Novo Nordisk (see Appendix 1, Section 10.1). 
8.1.2 
Continuous glucose monitoring  
Subjects will be equipped with a CGM device during the treatment periods from week 0 (V2) to 
week 4 (V6), and from week 22 (V24) to week 26 (V28) and during the follow-up period from 
week 26 (V28) to week 31 (V30). 
The CGM system used in this trial will be the Dexcom G6®. 
The CGM readings will be blinded to both the subject and investigator and will not be used for any 
insulin dose titration or hypoglycaemic episode reporting. 
If a subject withdraws consent during the trial, a site visit should be scheduled in order to remove 
the CGM sensor and upload the data from the receiver. 
CGM fitting and training  
The site staff will closely supervise and assist on fitting of the sensor and transmitter on the subject 
during the site visits. Training in the CGM is the responsibility of the investigator or site staff at the 
relevant visits. For information on fitting, and changing of the CGM parts, please refer to the 
manufacturer’s manual and subject guide provided. 
CGM Sensor Check  
The site staff should ensure that the subject has fitted the sensor correctly and that the CGM 
receiver is working. This will be done in person during the clinic visit, as specified in the flowchart

(Section 1.2). At the end of treatment visit (V28), the site should ensure the subject can change the 
sensor at home weekly during the follow-up period.  
CGM Upload 
Data stored on the CGM receiver must be uploaded at the site by the site staff to the CGM software 
following the instruction provided to the sites. The upload will be documented by the system 
directly. 
The serial number of the CGM receiver must be recorded in the eCRF at the start of each CGM 
period. In case the CGM receiver is being replaced, the serial number should be updated. 
8.1.3 
Clinical outcome assessments  
The patient reported outcome questionnaires are to be completed by the subject without assistance 
of the site personnel and should preferably be completed after all fasting-related activities are 
completed, but before any other visit related procedures are conducted. It takes approximately five 
minutes to complete the questionnaires. 
The following patient reported outcome questionnaires will be supplied in the eDiary in a 
linguistically validated version in all languages relevant for this trial: 
• Diabetes Treatment Satisfaction Questionnaire (DTSQs)  
o The questionnaire has been designed to measure satisfaction with diabetes treatment 
regimens in people with diabetes. The DTSQs questionnaire will be measured at 
baseline (V2) and end of treatment (V28).  
• Insulin preference questionnaire version 1.0 (IPQ)  
o The instrument assesses the preferences for specific insulin treatment in the trial 
setting and asks about the preference of a once weekly insulin (taken in the trial) 
compared with daily insulin (that was taken before the trial). The questionnaire will 
be measured at end of treatment (V28) in subjects treated with once weekly insulin 
icodec.  
• Diabetes Pen Experience Measure version 3.0 (DPEM)  
o The questionnaire is designed to measure subjects' experience of insulin injection 
pen in terms of easiness, convenience and satisfaction. The DPEM questionnaire will 
be measured at baseline (V2) and end of treatment (V28). 
8.1.4 
Clinical efficacy laboratory assessments 
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.

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 trial procedures performed before 
exposure to trial product.  
Medical history is a medical event that the subject experienced prior to the time point from which 
AEs are collected. Only relevant medical history as judged by the investigator will be recorded in 
the eCRF. 
In case of an abnormal and clinically significant finding fulfilling the definition of a concomitant 
illness or medical history, the investigator must record the finding on the Medical 
History/Concomitant Illness form. 
With regard to exclusion criteria 12 (Section 5.2), information on hypoglycaemia unawareness will 
be recorded according to Clarke's questionnaire, question 817. The investigator must ask the subject 
in the following way: "To what extent can you tell by your symptoms that your blood glucose is 
low?" Subjects answering 'never, rarely or sometimes' are considered to have impaired awareness of 
hypoglycaemia, whereas those answering “often or always” are not. 
8.2.1 
Insulin dose  
The prescribed insulin doses will be determined by the investigator in accordance with the titration 
guideline (Appendix 8, Section 10.8). 
During the trial, starting at randomisation (V2), subjects must be instructed to report date, dose and 
time of once weekly insulin or once daily insulin in the eDiary. In the follow-up period if the 
subject switches to a new basal insulin, the subject should also report date, dose and time of the new 
basal insulin in the eDiary. 
Please refer to Appendix 8 (Section 10.8) for more information. 
The investigator must record the following in the eCRF 
• 
First and last date on trial product 
• 
First and last dose of trial product 
For dosing of anti-diabetic medication prescribed in the follow-up period please see Section 6.5

Investigators should pay special attention to clinical signs related to previous serious illnesses.  
The physical examination will be recorded in the eCRF as either ‘normal’ or ‘abnormal’. If 
‘abnormal’, a comment must be given together with an assessment of clinical significance (yes/no).  
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 from baseline should be reported as an adverse event 
(Appendix 3, Section 10.3). 
Body measurements (height and weight) will also be measured and recorded. Height will be 
measured and recorded at screening visit (V1). Weight will be measured and recorded throughout 
the trial as specified in the flowchart (Section 1.2). 
o 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.  
o Body weight should be assessed with the same equipment throughout the trial, if 
possible. 
o Height should be measured in centimetres (cm) or inches (in) without shoes. Height 
will be recorded to the nearest whole number. 
o From the body weight and height, the BMI should be calculated and recorded in the 
subject’s medical records.  
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 subject in a quiet setting without distractions (e.g. no use of television, mobile 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 at screening (V1), V16, and end of treatment (V28) 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. Systolic blood pressure will be 
calculated as the mean of the last 2 systolic blood pressure readings, and diastolic blood 
pressure as the mean of the last 2 diastolic blood pressure readings. Only the last 2 systolic and 
last 2 diastolic blood pressure readings must be recorded in the eCRF.

8.2.4 
Electrocardiograms 
• A 12-lead ECG must be performed by the investigator or delegated staff as outlined in the 
flowchart (Section 1.2). 
• The ECG should be preceded by at least 5 minutes of rest for the subject in a supine/sitting 
position in a quiet setting without distractions (e.g. no use of television, mobile 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 2 weeks prior to V2 but at the latest at 
V2. The results must be interpreted by the investigator prior to randomisation in order to 
determine the eligibility of the subject. 
• The ECG required at the end of treatment visit can be obtained within 2 weeks prior to the end 
of treatment visit. The results must be available for evaluation at the end of treatment 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 from baseline should be reported as an adverse event 
(Appendix 3, Section 10.3).  
8.2.5 
Eye examination  
Subjects 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) 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 the subject 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 subject has experienced worsening of visual function since 
the last examination. Eye examinations performed prior to randomisation visit (V2) are acceptable 
if results are available for evaluation before randomisation. If the applicable eye examination was

performed before the subject signed the informed consent form, it must be documented that the 
reason for performing the examination was not related to this trial. 
Eye examinations required at the end of treatment (V28) visit can be performed within 2 weeks 
prior to the visit, if results are available for evaluation at the visit. For discontinued subjects, eye 
examination can be performed up to 2 weeks after the end of treatment visit. The investigator

Adverse events and serious adverse events 
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 events for adjudication and AEs requiring additional data collection. 
Some AEs require additional data collection on a specific event form. This always includes 
medication, misuse and abuse of IMP. The relevant events are in Table 8-1, together with events for 
adjudication. 
Hypoglycaemic episodes 
Hypoglycaemic episodes require data collection on a hypoglycaemic episode form in the eDiary. 
Non-serious hypoglycaemic episodes do not require an AE form to be filled in. If the 
hypoglycaemic episode fulfils the criteria for an SAE, then, in addition to the hypoglycaemic 
episodes form, an AE form and a safety information form must be filled in in the eCRF, please refer 
to Appendix 3. For more information on hypoglycaemic episodes, please refer to 
Appendix 7 (Section 10.7).

a All cerebrovascular events are to be reported and sent for adjudication, however the EAC will only confirm strokes. 
A detailed description of the events mentioned in the above table can be found in 
Appendix 3 (Section 10.3.3). 
Events for Adjudication 
Event adjudication will be performed in randomised subjects and will be evaluated by an 
independent external EAC in a blinded manner, please refer to Section 10.1.6.4. 
There are four ways to identify events relevant for adjudication as described below:  
• 
Investigator-reported events for adjudication: investigator selects the appropriate AE 
category relevant for adjudication (Appendix 3, Section 10.3.3). 
• 
AEs reported with fatal outcome.  
• 
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 eCRF.  
• 
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 eCRF 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 eCRF within 14 days. 
Copies of source documents should be uploaded to the event adjudication system (EAS) as soon as 
possible and preferably within 4 weeks. In cases where the EAS is not accessible the investigator 
should ensure that the relevant source documents are collected and saved locally until the EAS is 
ready. 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. 
An event adjudication site manual will be provided to each site detailing which source documents 
are relevant and how these should be provided to the adjudication supplier. The anonymization and 
labelling requirements are also described in the event adjudication site manual. 
8.3.1 
Time period and frequency for collecting AE and SAE information 
All AEs and SAEs must be collected from the randomisation visit and until the end of trial visit as 
specified in the flowchart (Section 1.2). For subjects discontinuing trial product prematurely AEs 
must be collected until the discontinuation follow-up visit (V28A). 
Medical occurrences that take place or have onset prior to the time point from which AEs are 
collected will be recorded as concomitant illness/medical history. 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 trial subjects. However, if 
the investigator learns of any SAE, including a death, at any time after a subject has been 
discontinued from/completed the trial, and the investigator considers the event to be 
possibly/probably related to the trial product or related to trial participation, the investigator must 
promptly notify Novo Nordisk. 
8.3.2 
Method of detecting AEs and SAEs 
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 subject is the preferred method to inquire about events. 
8.3.3 
Follow-up of AEs and SAEs 
After the initial AE/SAE report, the investigator is required to proactively follow each subject at 
subsequent visits/contacts. All SAEs should be followed until final outcome of the event or the 
subject 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 SAEs 
Prompt notification by the investigator to Novo Nordisk or designee of a SAE is essential so that 
legal obligations and ethical responsibilities towards the safety of subjects and the safety of a trial 
product 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 trial product 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 (SUSAR). 
An investigator who receives an investigator safety report describing a SAE or other specific safety 
information (e.g. summary or listing of SAEs) from Novo Nordisk will review and then file it along 
with the investigator's brochure and will notify the IRB/IEC, if appropriate according to local 
requirements.

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 10.3.3) for further details. 
In the event of an overdose, the investigator should closely monitor the subject for overdose-related 
AE/SAE and laboratory abnormalities until the blood glucose is normalised and (or) 
signs/symptoms have been relieved. 
A specific overdose for insulin icodec cannot be defined; however, hypoglycaemia may develop 
over sequential stages if the doses administered are too high relative to the subject’s requirements.  
• 
Mild hypoglycaemia can be treated by oral administration of glucose or sugary products.  
• 
Severe hypoglycaemia, where the subject 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, or by 
glucose given i.v. by a medical professional. Glucose must also be given i.v., if the subject 
dose not respond to glucagon within 10-15 minutes. If the subject has been unconscious, 
administration of oral carbohydrates is recommended for the subject 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 subject. 
For more information on overdose, also consult the current version of the insulin icodec 
investigator’s brochure11 or insulin degludec investigator’s brochure12. 
8.5 
Pharmacokinetics 
Blood samples will be used to evaluate the pharmacokinetics (PK) of insulin icodec. PK samples 
will be collected at the visits outlined in the flowchart (Section 1.2) for subjects randomised to 
insulin icodec. The date and exact clock time for blood sampling must be recorded. 
Bioanalysis of insulin icodec samples will be performed at a special laboratory using a validated 
luminescent oxygen channelling immunoassay. The exact method will be described in a 
bioanalytical report. 
Residual PK samples may be used for exploratory metabolite analysis. Potential metabolite analysis 
will be reported separately from the clinical trial report.  
Genetic analyses will not be performed on these plasma/serum/whole blood samples. Subject 
confidentiality will be maintained.  
Procedures for sampling, handling, storage, labelling and shipments of the specimens must be 
performed in accordance with the laboratory manual. A randomisation list will be provided to the

8.9.1 
Anti-drug antibodies  
Anti-drug antibody samples will be collected according to the flowchart (Section 1.2) for subjects 
randomised to insulin icodec. All samples must be drawn prior to trial product administration if trial 
product administration is planned on the sampling day. Assessment of antibodies against insulin 
icodec (anti-drug antibodies) in serum will be performed at a Novo Nordisk appointed laboratory. 
For details on blood sampling, serum preparation and storage, please refer to the laboratory manual. 
Analysis for anti-drug antibody will be done as listed in flowchart with a binding anti-drug antibody 
assay. Positive samples will be further characterised for titre, and cross-reactivity to endogenous 
human insulin. 
Detailed description of the assay methods will be included in an analytical report. Antibody assays 
will be validated according to international guidelines and recommendations. 
At the end of the trial, the following data will be electronically transferred to the Novo Nordisk 
database: Anti-insulin icodec binding antibodies (pos/neg) and titre of anti-drug antibody positive 
samples, and anti-insulin icodec binding antibodies cross-reacting with endogenous human insulin 
status (pos/neg). 
The investigator will not be able to review the results of antibody measurements in relation to AEs 
as the samples are often analysed after last subject last visit. Results from the binding anti-drug 
antibody analyses from visit randomisation (V2), V4, V8, V12, V20, end of treatment (V28) and 
end of trial visit (V30) will be available after the completion of the trial.

8.9.2 
Hypersensitivity  
Subjects and investigators will be instructed to detect signs and symptoms of systemic 
hypersensitivity.  
For subjects randomised to insulin icodec: In the event of a systemic hypersensitivity (not locally at 
the injection site), the subject should be called in as soon as possible to have additional blood 
samples taken in order to analyse the following parameters: 
• 
Tryptase (optimal 0.5-2 hours post the hypersensitivity reaction) 
• 
Total immunoglobulin E (IgE) antibodies 
• 
Anti-insulin icodec IgE antibodies 
• 
Anti-insulin icodec binding antibodies 
• 
Anti-human insulin IgE antibodies 
The blood sampling should be repeated 2-4 weeks following onset of the systemic hypersensitivity 
reaction. If possible, the tests should also be performed on samples drawn prior to first 
administration of trial drug. 
For details related to blood sampling, plasma preparation and storage, please refer to the laboratory 
manual. 
Analysis will be performed by Novo Nordisk or a Novo Nordisk appointed special laboratory 
(please refer to Attachment I). The results will be reported in a separate report and attached to the 
clinical trial report. 
If the reaction is classified as a SAE, the results from the hypersensitivity tests will also be reported 
to Novo Nordisk Safety Operations for inclusion in the ARGUS database and included in the 
narratives of the clinical trial report. 
For retention of residual hypersensitivity samples, please refer to Section 10.6. 
Digital pictures 
The investigator or the subject must take digital pictures of the affected area at time of 
identification, using any device available (mobile phone, camera etc.) and thereafter as often as 
judged necessary by the investigator. The pictures should include subject identification number, 
date and time, time after dosing and a ruler for scaling. All pictures must be stored as part of source 
documentation at site.

Statistical considerations  
9.1 
Statistical hypotheses 
The primary hypothesis to be tested is that insulin icodec is non-inferior to insulin degludec in terms 
of change from baseline to week 26 in HbA1c. 
Formally, let D be the treatment difference ‘insulin icodec’ minus ‘insulin degludec’ of the change 
in HbA1c from baseline to week 26. The null-hypothesis will be tested against the alternative 
hypothesis of non-inferiority as given by  
H0: D≥0.30% against HA: D <0.30% 
The non-inferiority margin of 0.3%-point is chosen based on the recommendation in the FDA 
guidance for industry on developing drugs for treatment of diabetes.18 Also, this margin is 
considered to provide sufficient assay sensitivity based on the below considerations: 
• 
The margin does not represent an unacceptable loss of efficacy with insulin icodec relative 
to treatment with a basal insulin analogue 
• 
It represents less than 50% of a suitably conservative estimate of insulin degludec’s 
treatment effect on HbA1c in a placebo-controlled trial in a basal insulin treated population; 
The treatment effect of degludec versus placebo in a basal insulin treated population is 
unknown but in a similar progressed T2D population of subjects already treated with 
liraglutide, degludec was shown to be superior to placebo (estimated treatment difference: -
0.92%-point [-1.00; -0.75] 95%CI).19 
The following describe the secondary confirmatory hypothesis. In order to control the overall Type 
I error at a 5% level, two sided, a hierarchical testing procedure will be used. If non-inferiority in 
glycaemic control is concluded in the primary analysis, confirmatory testing proceeds to the 
following hypothesis: 
• Insulin icodec is superior to insulin degludec in terms of change from baseline to week 26 in 
HbA1c. 
Formally, let D be the mean treatment difference ‘insulin icodec’ minus ‘insulin degludec’ of the 
change in HbA1c from baseline to week 26. The null-hypothesis of insulin icodec not superior will 
be tested against the alternative hypothesis of superiority as given by 
H0: D≥0% against HA: D<0%

9.2 
Sample size determination  
The sample size is determined in order to have 90% power for declaring non-inferiority with a non-
inferiority margin of 0.3%-point with respect to change in HbA1c for the specified estimand and the 
full analysis set (primary analysis set). 
Based on recent studies with basal insulins (NN9068-4185 and 4229) the percent experiencing an 
intercurrent event as specified above is expected to be 5% per 6 months in an open label study in 
subjects with T2D treated with basal insulin. 
It is assumed that there is no difference in HbA1c between the treatment arms for subjects 
completing randomised treatment without initiation of treatment with bolus insulin for more than 2 
weeks and a treatment difference of 0.3%-point in favour of the comparator for subjects either 
discontinuing treatment prematurely, initiating treatment with bolus insulin for more than 2 weeks 
or withdrawing from trial. Thus, with 5% expected to experience any of the specified intercurrent 
events before week 26, this leads to an assumption of a mean treatment difference of 0.015%-point 
for the specified estimand in the overall population.  
The SD is assumed to be 1.0%-point based on results from studies with insulin degludec in subjects 
treated with basal insulin (NN1250-3998).  
From the above assumptions and requirements, 520 subjects will be randomly assigned to trial 
product. This will ensure sufficient power (90%) of confirming non-inferiority. 
Assuming 25% screening failures, approximately 693 subjects will be screened to achieve 520 
subjects randomly assigned to trial product.  
This sample size appears to be reasonable also under deviations from the assumed treatment 
difference as illustrated in Table 9-1 displaying power for various alternative treatment differences 
and SD. 
For the hypothesis of superiority of insulin icodec compared to insulin degludec in terms of change 
from baseline to week 26 in HbA1c, there will be 49% marginal power and also 49% combined 
power to detect if the true treatment difference in HbA1c is 0.18%-point with the sample size of 520.

Populations for analyses 
The following populations are defined: 
Population 
Description 
Randomised 
All subjects randomised 
Full analysis set  
Full analysis set: All subjects randomised. Subjects will be analysed according to 
the randomised treatment.  
Safety analysis set 
All subjects randomly assigned to trial treatment and who take at least 1 dose of 
trial product. Subjects are analysed according to the treatment they actually 
received.  
In exceptional cases, subjects or observations may be eliminated from the full analysis set. In such 
case the reasons for their exclusion will be documented before unblinding. The subjects and 
observations excluded from analysis sets, and the reason for this, will be described in the clinical 
trial report. 
The following periods will be considered for the data collected: 
In-trial period 
The in-trial period starts at randomisation and ends at the date of: 
• The last direct subject-site contact 
• Withdrawal for subjects who withdraw their informed consent 
• The last subject-investigator contact as defined by the investigator for subjects who are lost to 
follow-up (i.e. possibly an unscheduled phone visit) 
• Death for subjects who die before any of the above 
For subjects not randomised but exposed to trial product the in-trial period starts at the date of first 
dose of trial product. The end date is as defined as above.  
On-treatment period 
The on-treatment period starts at the date of first dose of trial product as recorded on the eCRF, and 
ends at the first date of any of the following: 
• The end of trial visit (V30) 
• The last date on trial product + 5 weeks for once daily insulin and + 6 weeks for once weekly 
insulin (corresponding to 5 weeks after the end of the dosing interval for both treatment arms) 
• The end-date for the in-trial observation period 
The on-treatment period represents the time period in which a subject is considered exposed to trial 
product. 
All efficacy endpoints will be summarised and analysed using the full analysis set and the ‘in-trial’ 
period. Safety endpoints will be evaluated using the on-treatment period with descriptive statistics

Statistical analyses 
The statistical analysis plan (SAP) will be finalised prior to first subject 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 primary and secondary endpoints. 
9.4.1 
General considerations 
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: 
• Treatment: Once weekly insulin icodec, insulin degludec  
• Region: Asia, Europe, North America, Africa  
The regions will be defined as follows:  
• Asia: Japan, South Korea 
• Europe: Bulgaria, Germany, Poland, Portugal, Ukraine 
• North America: United States 
• Africa: South Africa 
The last available assessment made prior to the first dose will be used as the baseline value. 
All endpoints based on CGM measurements will be derived the following way. The percentage of 
time spent in a given glycaemic range will be calculated as 100 times the number of recorded 
measurements in the given glycaemic range, divided by the total number of recorded measurements. 
Following international consensus criteria it will be required that at least 70% of the planned CGM 
measurements during the last four weeks of treatment are available for endpoint data to be included 
in the analysis.20 
9.4.2 
Primary endpoint 
The primary endpoint is change in HbA1c from baseline to week 26. 
The ‘treatment policy’ estimand, will be estimated based on the full analysis set using all HbA1c 
measurements obtained at the week 26 visit, especially including measurements from subjects 
discontinuing their randomised treatment or initiating treatment with bolus insulin for more than 2 
weeks. Missing HbA1c values at the week 26 visit (regardless of treatment completion status) will 
be imputed from trial participants, who have discontinued their randomised treatment or initiated

treatment with bolus insulin for more than 2 weeks prior to the week 26 visit and have a 
measurement at the week 26 visit in the following way: 
• First, one thousand (1000) copies of the dataset will be generated for HbA1c.  
• Second, for subjects who discontinued their randomised treatment or initiated treatment with 
bolus insulin for more than 2 weeks at any time prior to the week 26 visit and have an HbA1c 
measurement at the week 26 visit, the change in HbA1c from last available planned on-
treatment without initiation of treatment with bolus insulin for more than 2 weeks (LAOT-
WOB) value to the week 26 visit will be analysed for each dataset copy using an analysis of 
covariance (ANCOVA) model with randomised treatment as fixed factor and LAOT-WOB 
value and the time point (study day) of this assessment as covariates. The estimated 
parameters, and their variances, from the model will be used to impute missing HbA1c values 
for the change from LAOT-WOB to the week 26 visit and subsequently the missing HbA1c 
value at the week 26 visit. 
• 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 a 
covariate. The estimates and SDs for the 1000 data sets will be pooled to one estimate and 
associated SD using Rubin’s rule.21 
This analysis has the underlying assumption that subjects with missing data behave similarly as 
subjects that discontinue randomised treatment or initiate treatment with bolus insulin for more than 
2 weeks. 
If non-inferiority is confirmed, i.e. if the 95% CI is strictly below 0.3%, then the primary endpoint 
will further be tested for superiority. Superiority for change in HbA1c will be considered confirmed 
if the 95% CI is strictly below zero. 
The following sensitivity analysis evaluating the robustness of the assumptions about the missing 
data will be carried out: 
For the primary endpoint, a two-dimensional tipping point analysis will be performed where 
subjects having imputed HbA1c measurement at the week 26 visit are assumed to have a worse 
outcome in the insulin icodec arm and a better outcome in the insulin degludec arm compared to 
what was imputed in the primary analysis. This is done by adding or subtracting values Δi to the 
imputed HbA1c values before analysing the data. The value of Δi will be varied independently in the

The plausibility of the values of Δi where the conclusion of the primary analysis change will be

Supportive secondary endpoints 
Supportive secondary endpoints will be evaluated in the framework of the primary estimand. 
Efficacy endpoints 
Change in fasting plasma glucose (FPG) from baseline week 0 (V2) to week 26 (V28) 
Missing FPG values at the week 26 visit (regardless of treatment completion status) will be imputed 
from trial participants who are from the insulin degludec group, and who have completed and 
adhered to their randomised insulin treatment without initiation of bolus insulin treatment for more 
than 2 weeks at any time prior to the week 26 visit – i.e., data will be imputed based on the 
assumption that subjects with missing endpoint data will behave like subjects completing the insulin 
degludec treatment without initiation of bolus insulin treatment for more than 2 weeks at any time 
prior to the week 26 visit. Specifically, the imputations and analyses will be carried as follows: 
• First, one thousand (1000) copies of the dataset will be generated for FPG. 
• Second, for each dataset copy, an analysis of covariance (ANCOVA) model with a baseline 
value as a covariate will be fitted to FPG values for subjects who completed their randomised 
treatment without initiation of bolus insulin treatment for more than 2 weeks at any time prior 
to the week 26 visit in the insulin degludec group. The estimated mean, and variances, from 
the model will be used to impute missing values in both treatment groups. 
• For each of the completed 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 Rubin’s rule.21 
Time in target range 3.9-10.0 mmol/L (70-180 mg/dL), from week 22 (V24) to week 26 (V28) 
Time in target range 3.9-10.0 mmol/L (70-180 mg/dL) from week 22 to week 26 will be analysed 
using the same model as specified for change in FPG, but without using the baseline value as a 
covariate. 
Change in DTSQs (Diabetes Treatment Satisfaction Questionnaire) in total treatment 
satisfaction from baseline week 0 (V2) to week 26 (V28) 
The change in DTSQs in total treatment satisfaction from baseline to week 26 will be analysed 
using the same model as specified for change in FPG, but the corresponding baseline value will be 
used as a covariate.

Safety endpoints 
Hypoglycaemic episodes 
The following hypoglycaemic endpoints will be analysed separately using the method described 
below: 
• Number of severe hypoglycaemic episodes (level 3) from baseline week 0 (V2) to week 31 
(V30) 
• Number of clinically significant hypoglycaemic episodes (level 2) (<3.0 mmol/L (54 mg/dL), 
confirmed by BG meter) from baseline week 0 (V2) to week 31 (V30) 
• Number of clinically significant hypoglycaemic episodes (level 2) (<3.0 mmol/L (54 mg/dL), 
confirmed by BG meter) or severe hypoglycaemic episodes (level 3) from baseline week 0 
(V2) to week 31 (V30) 
For subjects who discontinued their randomised treatment, the number of episodes in the missing 
period (time of follow-up 2 (V30) to planned end of the on-treatment period) will be imputed using 
a multiple imputation technique, assuming that the event rate pre follow-up 2 (V30) follows the 
respective treatment groups rate whilst post follow-up 2 (V30) event rate is the rate of the insulin 
degludec group. The imputation will be done as follows: 
• First, a Bayes negative binomial model with log-link function will be fitted to the event rate 
data to obtain the posterior distribution of model parameters. The model will include region 
and randomised treatment as fixed factors and the logarithm of the on-treatment period as 
offset. 
• Second, based on the estimated parameters for the insulin degludec group in this model, the 
number of episodes in the missing period will be imputed for subjects who discontinued their 
randomised treatment. Multiple copies (1000 copies) of a complete data set will be generated 
by sampling from the estimated distribution.  
• For each of the complete data sets, the number of episodes will be analysed using a negative 
binomial model with log-link, fixed factors and offset as described in step 1. The estimates and 
SDs for the 1000 data sets will be pooled to one estimate and associated SD using Rubin’s 
rule.21 
For the definition and classification of hypoglycaemic episodes refer to Appendix 7 (Section 10.7). 
Time spent < 3.0 mmol/L (54 mg/dL) and time spent > 10 mmol/L (180 mg/dL) from week 22 
(V24) to week 26 (V28) 
Time spent < 3.0 mmol/L (54 mg/dL) (below range) and time spent > 10 mmol/L (180 mg/dL) 
(above range) from week 22 to week 26 will be analysed separately using the same model as 
specified for change in FPG, but without using the baseline value as a covariate. This model will be 
used if deemed appropriate, i.e. if data can be considered normally distributed. However, if a large 
number of subjects have 0% time spent, then an alternative analysis will be performed either

considering the endpoint as a dichotomous endpoint or by applying a censored analysis of the log-
transformed values. Further details will be provided in the SAP. 
Mean weekly insulin dose from week 24 (V26) to week 26 (V28) 
Mean weekly insulin dose during the last 2 weeks of treatment (from week 24 to 26) will be log-
transformed and analysed using the same model as specified for change in FPG, but with using the 
log-transformed weekly insulin dose at screening as a covariate. 
Change in body weight from baseline week 0 (V2) to week 26 (V28) 
Change in body weight from week 0 to week 26 will be analysed using the same statistical model as 
specified for the primary endpoint, but with the corresponding baseline value as a covariate.

Pharmacokinetic modelling  
Insulin icodec serum concentration data will be used for population PK analysis. The objective of 
the population PK analysis is to evaluate the effects of pre-specified covariates on serum 
concentrations of insulin icodec. 
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, a previously 
developed PK model for insulin icodec will be applied. The absorption rate constant (Ka) in the 
model will be fixed, and the apparent clearance (CL/F) and the apparent volume of distribution 
(V/F) will be re-estimated. The covariates of interest will be incorporated into the PK model using 
criteria which will be specified in the modelling analysis plan.

Data quality assurance 
10.1.8.1 
Case report forms 
• Novo Nordisk or designee is responsible for the data management of this trial including quality 
checking of the data. 
• All subject data relating to the trial will be recorded on electronic CRFs (eCRFs) unless 
transmitted electronically to Novo Nordisk (e.g. laboratory and eDiary data) or when 
applicable on paper CRF. 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:  
o Pregnancy forms 
• The following will be provided as paper CRFs to be used when access to the eCRF is revoked 
or the eCRF is temporarily unavailable: 
o Adverse event forms  
o Safety information forms 
o Technical complaint forms (also to be used to report complaints on trial product not 
yet allocated to a subject)  
• Corrections to the CRF data may be made by the investigator or the investigator’s delegated 
staff. An audit trail will be maintained in the CRF application containing as a minimum: the 
old and the new data, identification of the person entering the data, date and time of the entry 
and reason for the correction. If corrections are made by the investigator’s delegated staff after 
the date when the investigator signed the CRF, the CRF must be signed and dated again by the 
investigator. 
• The investigator must ensure that data is recorded in the CRF as soon as possible, preferably 
within 5 working days after the visit. Once data has been entered, it will be available to Novo 
Nordisk for data verification and validation purposes.  
10.1.8.2 
Monitoring 
• The investigator must permit trial-related monitoring, audits, IRB/IEC review, and regulatory 
agency inspections and provide direct access to source data documents (original documents,

any record(s) and report(s) that are important to the evaluation of the trial. If the electronic 
medical record does not have a visible audit trail, the investigator must provide the monitor 
with signed and dated printouts. In addition, the relevant site staff should be available for 
discussions at monitoring visits and between monitoring visits (e.g. by telephone).  
• Trial monitors will perform ongoing source data verification to confirm that data entered into 
the eCRF by authorised site personnel are accurate, complete and verifiable from source 
documents; that the safety and rights of subjects are being protected, to monitor drug 
accountability and collect completed paper CRF pages, if applicable, and that the trial is being 
conducted in accordance with the currently approved protocol and any other trial agreements, 
ICH GCP, and all applicable regulatory requirements. 
• 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.  
• Monitors will review the subject’s medical records and other source data to ensure consistency 
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 eCRF or via listings from the trial database. 
10.1.9 
Source documents 
All data entered in the eCRF must be verifiable in source documentation, except for the following 
data that has been transferred directly into the database and will be considered source data: 
• For e.g. electronic patient reported outcomes, eDiary, data in the service providers’ database is 
considered source data. 
• Source documents provide evidence for the existence of the subject and substantiate the 
integrity of the data collected. Source documents are filed at the site. 
• Data reported on the paper CRF or entered in the eCRF that are transcribed from source 
documents must be consistent with the source documents, or the discrepancies must be 
explained. The investigator may need to request previous medical records or transfer records. 
Also, current medical records must be available.  
• It must be possible to verify subject’s medical history in source documents, such as subject’s 
medical record.  
• The investigator must document any attempt to obtain external medical information by noting 
the date(s) when information was requested, and who was contacted.

in any way. If applicable, electronic CRF (eCRF) and other subject data will be provided in an 
electronic readable format to the investigator before access is revoked to the systems supplied 
by Novo Nordisk. Site-specific CRFs and other subject data (in an electronic readable format 
or as paper copies or prints) must be retained by the site. A copy of all data will be stored by 
Novo Nordisk. 
• Subject’s medical records must be kept for the maximum period permitted by the hospital, 
institution or private practice. 
10.1.11 
Trial and site closure 
Novo Nordisk reserves the right to close the site or terminate the trial at any time for any reason at 
the sole discretion of Novo Nordisk. If the trial is suspended or terminated, the investigator must 
inform the subjects promptly and ensure appropriate therapy and follow-up. The investigator and/or 
Novo Nordisk must also promptly inform the regulatory authorities and IRBs/IECs and provide a 
detailed written explanation. 
Sites will be closed upon trial completion. A site is considered closed when all required documents 
and trial 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 subjects by the investigator 
• discontinuation of further trial product development.

Novo Nordisk commits to communicate and disclose results of trials regardless of outcome. 
Disclosure includes publication of a manuscript in a peer-reviewed scientific journal, abstract 
submission with a poster or oral presentation at a scientific meeting or disclosure by other means. 
The results of this trial will be subject to public disclosure on external web sites according to 
international and national regulations. Novo Nordisk reserves the right to defer the release of data 
until specified milestones are reached, for example when the clinical trial report is available. This 
includes the right not to release the results of interim analyses, because the release of such 
information may influence the results of the entire trial. 
At the end of the trial, one or more scientific publications may be prepared collaboratively by the 
investigator(s) and Novo Nordisk. Novo Nordisk reserves the right to postpone publication and/or 
communication for up to 60 days to protect intellectual property. 
In all cases, the trial results will be reported in an objective, accurate, balanced and complete 
manner, with a discussion of the strengths and limitations. In the event of any disagreement on the 
content of any publication, both the investigators’ and Novo Nordisk opinions will be fairly and 
sufficiently represented in the publication.

Authorship 
Novo Nordisk will work with one or more investigator(s) and other experts who have contributed to 
the trial concept or design, acquisition, analysis or interpretation of data to report the results in one 
or more publications. 
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.28 
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 trial, analyses based on single-site data usually have significant statistical 
limitations and frequently do not provide meaningful information for healthcare professionals or 
subjects, and therefore may not be supported by Novo Nordisk. 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 trial. 
10.1.14.4 
Investigator access to data and review of results 
As owner of the trial database, Novo Nordisk has the discretion to determine who will have access 
to the database. 
Individual investigators will have their own research subjects’ data and will be provided with the 
randomisation code after results are available.

Appendix 2: Clinical laboratory tests 
• The tests detailed in Table 10-1 and Table 10-2 will be performed by the central laboratory. 
• Additional tests may be performed at any time during the trial 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 lab 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 lab SOPs. These data will not be transferred to the trial 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. 
• Laboratory samples will be destroyed no later than at finalisation of the clinical trial report, 
except the following:  
• 
For haematology samples (differential count) where the test result is not normal, then a part 
of the sample may be kept for up to two years or according to local regulations.  
• 
Human biosamples for retention will be stored as described in Appendix 6 (Section 10.6).

Appendix 3: Adverse events: Definitions and procedures for recording, evaluation, 
follow-up, and reporting 
10.3.1 
Definition of AE 
AE definition 
An AE is any untoward medical occurrence in a clinical trial subject that is temporally associated 
with the use of an investigational medicinal product (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 meeting the AE definition 
• 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 
A "lack of efficacy" or "failure of expected pharmacological action" per se will not be reported as 
an 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 meeting the AE definition  
• Conditions present prior to the time point from which AEs are collected and anticipated day-
to-day fluctuations of these conditions, including those identified during screening or other 
trial 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 an SAE 
An SAE is an AE that fulfils at least one of the following criteria: 
a. Results in death 
b. Is life-threatening 
The term 'life-threatening' in the definition of 'serious' refers to an event in which the subject was 
at risk of death at the time of the event. It does not refer to an event which hypothetically might 
have caused death, if it were more severe. 
c. Requires inpatient hospitalisation or prolongation of existing hospitalisation 
• Hospitalisation signifies that the subject has been detained at the hospital or emergency ward 
for observation and/or treatment that would not have been appropriate in the physician’s 
office or outpatient setting. Complications that occur during hospitalisation are AEs. If a 
complication prolongs hospitalisation or fulfils any other seriousness criteria, the event is 
serious. When in doubt as to whether “hospitalisation” occurred or was necessary, the AE 
should be considered serious. 
• 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. 
Note:  
• Hospitalisations for administrative, trial related, social and convenience reasons do not 
constitute AEs and should therefore not be reported as AEs or SAEs.  
• Hospital admissions for medical or surgical procedures, planned before trial inclusion, are not 
considered AEs or SAEs.  
d. Results in persistent or significant disability/incapacity 
• The term disability means a substantial disruption of a person’s ability to conduct normal life 
functions. 
• This definition is not intended to include experience of relatively minor medical significance, 
such as uncomplicated headache, nausea, vomiting, diarrhoea, influenza, and accidental 
trauma (e.g. sprained ankle), which may interfere with or prevent everyday life functions but 
do not constitute a substantial disruption. 
e. Is a congenital anomaly/birth defect 
f. Important medical event: 
• Medical or scientific judgment should be exercised 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 
subject 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 adverse events must always be reported as SAEs using the important medical 
event criterion if no other seriousness criteria are applicable: 
• Suspicion of transmission of infectious agents via the IMP  
• Risk of liver injury defined as alanine aminotransferase or aspartate 
aminotransferase >3 x UNL and total bilirubin >2 x UNL where no alternative aetiology 
exists (Hy's law)

Description of events for adjudication and AEs requiring additional data collection  
Description of events for adjudication and AEs requiring additional data collection (on

Events for adjudication 
An event for adjudication is a selected AE or death evaluated by an independent external EAC in 
a blinded manner, please refer to Table 8-1 Appendix 1 (Section 10.1.6.4) and Figure 10-1. 
• Death 
• All cause death 
• Acute coronary syndrome 
• All types of acute myocardial infarction and unstable angina pectoris requiring 
hospitalisation 
• Cerebrovascular event (stroke or 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 or urgent heart failure visit) 
• New episode or worsening of existing heart failure leading to an urgent, unscheduled 
hospital admission or clinic/office/emergency department visit 
Adverse events requiring additional data collection 
AEs requiring additional data collection on a specific event form. 
Injection site reaction 
If an event of injection site reaction is observed, additional information must be obtained if 
available on a separate form. 
Hypersensitivity 
Systemic hypersensitivity can be manifested as isolated symptoms such as urticaria, angioedema, 
conjunctivitis, rhinitis, bronchospasm, gastrointestinal symptoms (nausea, vomiting, diarrhea, 
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 circulation29. 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 basophils30. 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 (DHRs) are the adverse effects of pharmaceutical formulations 
(including active drugs and excipients) that clinically resemble allergy31. They can be allergic and 
non-allergic. 
If a hypersensitivity event is suspected, the subjects 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. 
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 subject, 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 trial 
subject were likely to happen as judged by the investigator, although they did not 
necessarily occur. 
• missed doses or drug pauses are not to be reported as a medication error. 
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) 
Medication error, misuse and abuse must always be reported as an AE (e.g. accidental overdose, 
intentional overdose or other) on a separate AE form, and a medication error, misuse and abuse 
form must be completed. In case of a medication error and/or misuse and abuse resulting in a 
clinical consequence, this must be reported on an additional AE form.

Recording and follow-up of AE and/or SAE 
AE and SAE 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 subject identifiers, with the 
exception of the subject number, will be redacted on the copies of the source documents 
before submission to Novo Nordisk. 
• For all non-serious AEs, the applicable forms should be signed when the event is resolved or 
at the end of the trial at the latest. For sign-off of SAE related forms, refer to “AE and SAE 
reporting via paper CRF” later in this section. 
• 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 or NIMP or 
concomitant medication in the trial, it is important that the suspected relationship is reported 
to Novo Nordisk, e.g. in the alternative aetiology section on the safety information form. 
Novo Nordisk may need to report this adverse event to relevant regulatory authorities. 
 
Assessment of severity 
The investigator will assess severity for each event reported during the trial and assign it to one of 
the following categories:  
• Mild: An event that is easily tolerated by the subject, 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 a SAE. Both AEs and 
SAEs can be assessed as severe.

Assessment of causality 
• The investigator is obligated to assess the relationship between IMP and the occurrence of 
each AE/SAE. 
• Relationship between an AE/SAE and the relevant IMP(s) 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, will be 
considered and investigated. 
• The investigator should use the Investigator’s Brochures for insulin icodec and insulin 
degludec 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. 
Final outcome 
The investigator will select the most appropriate outcome: 
• Recovered/resolved: The subject 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 subject is expected to recover 
from the event. 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).  
• Note: For SAEs, this term is only applicable if the subject has completed the follow-up 
period and is expected to recover. 
• Recovered/resolved with sequelae: The subject has recovered from the condition but with 
lasting effect due to a disease, injury, treatment or procedure. If a sequela meets an SAE 
criterion, the AE must be reported as an SAE. 
• Not recovered/not resolved: The condition of the subject has not improved, and the 
symptoms are unchanged, or the outcome is not known.  
Note: 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 subject died from a condition related to the reported 
AE. Outcomes of other reported AEs in a subject before he/she died should be assessed as 
“recovered/resolved”, “recovering/resolving”, “recovered/resolved with sequelae” or “not 
recovered/not resolved”. An AE with a fatal outcome must be reported as an SAE. 
• Unknown: This term is only applicable if the subject is lost to follow-up.

Follow-up of AE and SAE 
The investigator is obligated to perform or arrange for the conduct of supplemental measurements 
and/or evaluations as medically indicated or as requested by Novo Nordisk to elucidate the nature 
and/or causality of the AE or SAE as fully as possible (e.g. severe hypersensitivity reactions). 
This may include additional laboratory tests (e.g. skin prick test) or investigations, 
histopathological examinations, or consultation with other health care professionals. 
If a subject dies during participation in the trial or during a recognised follow-up period, Novo 
Nordisk may request a copy of the autopsy report including histopathology. 
New or updated information will be recorded in the CRF. 
 
10.3.5 
Reporting of SAEs 
SAE reporting via electronic CRF 
• Relevant forms (AE and safety information form) must be completed in the CRF.  
• For reporting and sign-off timelines, see Figure 10-1. 
• If the CRF is unavailable for more than 24 hours, then the site will use the paper AE form, 
and if the CRF is unavailable for more than 5 calendar days, then the site will use the paper 
safety information form (see box below). 
• The site will enter the SAE data into the CRF as soon as it becomes available. 
• After the trial is completed, the trial 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 subject or receives updated data on a previously 
reported SAE after CRF decommission, then the site can report this information on a paper 
AE and safety information form (see box below) or to Novo Nordisk by telephone. 
 
AE and SAE reporting via paper CRF 
• Relevant CRF forms (AE and safety information form) must be forwarded to Novo Nordisk 
in accordance with Section 10.1.5. 
• 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 form within the 
designated reporting timelines (as illustrated in Figure 10-1): 
• AE form within 24 hours 
• Safety information form within 5 calendar days 
• Both forms must be signed within 7 calendar days after first knowledge by the 
investigator. 
• The specific event form for AEs requiring additional data collection within 14 calendar days

Appendix 4: Contraceptive guidance and collection of pregnancy information 
Definitions 
Woman of childbearing potential (WOCBP) 
A woman is considered fertile following menarche and until becoming postmenopausal unless 
permanently sterile. If fertility is unclear and a menstrual cycle cannot be confirmed before first 
dose of trial treatment, 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 
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 
trial enrolment. 
3. Postmenopausal female: 
• A postmenopausal state is defined as amenorrhoea for 12 months without an alternative medical 
cause.  
• Females ≥ 50 years of age can be considered postmenopausal (irrespective of treatment with a 
hormonal contraception or hormone replacement therapy (HRT)) if they have both: 
o Amenorrhoea and 
o Documentation of 2 high follicle stimulating hormone (FSH) measurements in the 
postmenopausal range and one of these was observed ≥1 year prior to screening. 
• Females ≥ 60 years of age can be considered postmenopausal. 
Females on HRT and whose menopausal status is in doubt are considered of childbearing potential 
and will be required to use at least an acceptable effective contraception methods as described in 
Table 10-3. 
Note: Documentation regarding categories 1-3 can come from the site staff’s review of subject’s 
medical records, medical examination or medical history interview. 
Contraception guidance 
Male subjects  
No contraception measures are required as the risk of teratogenicity/fetotoxicity caused by transfer 
of insulin icodec or insulin degludec in seminal fluid is unlikely32.

Female subjects 
Female subjects of childbearing potential are eligible to participate if they agree to use at least an 
acceptable effective methods of contraception consistently and correctly as described in Table 10-3. 
As a minimum, contraception should be maintained until treatment discontinuation33. 
Table 10-3 
Acceptable contraceptive methods 
CONTRACEPTIVESa ALLOWED DURING THE TRIAL INCLUDE: 
ACCEPTABLE METHODSb 
• Progestogen-only oral hormonal contraception where inhibition of ovulation is not the primary 
mode of action 
• Male or female condom with or without spermicidec 
• Cervical cap, diaphragm, or sponge with spermicide 
• A combination of male condom with either cervical cap, diaphragm, or sponge with 
spermicide (double-barrier methods). 
NOTES 
a) Contraceptive use by men or women should be consistent with local regulations regarding the 
use of contraceptive methods for those participating in clinical trials. 
b) Considered effective, but not highly effective - failure rate of ≥1% per year. Periodic 
abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), 
spermicides only, and lactational amenorrhoea method (LAM) are not acceptable methods of 
contraception. 
c) Male condom and female condom should not be used together (due to risk of failure with 
friction). 
 
Pregnancy testing 
• Additional pregnancy testing should be performed during the treatment period, if required 
locally. Please refer to the Appendix 9 (Section 10.9). 
• WOCBP should only be included after a negative highly sensitive urine pregnancy test (refer to 
Appendix 2 (Section 10.2) and the trial flowchart (Section 1.2). 
• As a minimum, pregnancy test should be performed at the end of relevant systemic exposure 
(refer to Appendix 2 and the trial flowchart). 
• Pregnancy testing should be performed whenever a menstruation is missed or when pregnancy 
is otherwise suspected.

Collection of pregnancy information  
Female subjects who become pregnant 
• Investigator will collect pregnancy information on any female subject who becomes pregnant 
while participating in this trial. 
• Information will be recorded on the appropriate form and submitted to Novo Nordisk within 14 
calendar days of learning of subject’s pregnancy (see Figure 10-2). 
• Subject will be followed to determine the outcome of the pregnancy. The investigators will 
collect follow-up information on subject 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 the foetal status (presence or 
absence of anomalies) or indication for procedure. 
• While pregnancy itself is not considered to be an AE or SAE, any adverse event in connection 
with pregnancy or elective termination of a pregnancy for medical reasons will be reported as 
an AE or SAE. If relevant, consider adding “gestational”, “pregnancy related” or similar term 
when reporting the AE/SAE. 
• Pregnancy outcome should be documented in the subject’s medical record. Abnormal 
pregnancy outcome (e.g. spontaneous abortion, foetal death, stillbirth, congenital anomalies 
and ectopic pregnancy) is considered an SAE. 
• Any SAE occurring as a result of a post-trial pregnancy which is considered possible/probably 
related to the IMP by the investigator will be reported to Novo Nordisk as described in 
Appendix 3 (Section 10.3) . While the investigator is not obligated to actively seek this 
information in former subjects, he/she may learn of an SAE through spontaneous reporting.

Appendix 5: Technical complaints: Definition and procedures for recording, 
evaluation, follow-up and reporting 
10.5.1 
Definition of technical complaint 
Technical complaint definition  
• 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 trial products (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 
Contact details for Customer Complaint Center, please refer to Attachment I. 
Technical complaints must be reported on a separate technical complaint form: 
1. One technical complaint form must be completed for each affected DUN. 
2. If DUN is not available, a technical complaint form for each batch, code or lot number must 
be completed. 
 
Timelines for reporting of 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 trial product that is not 
yet allocated to subject, 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.

Follow-up of technical complaints  
The investigator is responsible for ensuring that new or updated information will be recorded on 
the originally completed form. 
 
Collection, storage and shipment of technical complaint samples 
The investigator must collect the technical complaint sample and all associated parts that were 
packed in the same DUN 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 product. 
 
10.5.3 
Reporting of technical complaints 
Reporting of technical complaints for Novo Nordisk products not included in technical 
complaint form

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 8.9.2) 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 Novo Nordisk or a Novo Nordisk designated referral central bio-
repository. 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 (CRO) for analysis. 
The samples will be anonymised (identified only by a unique sample ID, visit number, trial 
identification number and sampling date). Confidentiality and personal data protection will be 
ensured during storage after the end of trial and no direct identification of the subject will be stored 
together with the samples.  
Potential further analyses of the samples will not have any consequences for the subject and their 
relatives. Subjects 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 after end of trial and until marketing authorisation approval or until the 
research project terminates, but no longer than 15 years from end of trial after which they will be 
destroyed. 
Antibody samples 
Antibody samples may be retained for further characterisation of antibody responses towards drug, 
if required by health authorities or for safety reasons. The samples may also be used for further 
development of anti-insulin antibody assays, or for exploratory investigation of antibodies. 
The antibody samples will be stored after end of trial and until marketing authorisation approval or 
until the research project terminates, but no longer than 15 years from end of trial after which they 
will be destroyed. 
Metabolism samples (PK samples) 
Samples for metabolism analysis may be retained for later analysis of metabolites if needed. If 
samples are selected for metabolite analysis, they will be stored at Novo Nordisk after end of trial 
and until marketing authorisation approval or until the research project terminates, but no longer 
than 15 years from end of trial after which they will be destroyed.

1Hypoglycaemia associated with severe cognitive 
impairment requiring external assistance for recovery 
Notes: The Novo Nordisk terms are adapted from IHSG34, ADA35, ISPAD36, type 1 diabetes outcomes program37, 
ATTD20. Severe hypoglycaemia as defined by Seaquist38 and ISPAD36. 
 
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 
concentration38. 
In case of recurrent severe hypoglycaemia, the treatment of the subject is the responsibility of the 
investigator and the titration guidelines can be overruled at his/her discretion35.  
Nocturnal hypoglycaemia 
Nocturnal hypoglycaemic episodes: episodes occurring between 00:01 and 05:59 both inclusive. 
Reporting of hypoglycaemic episodes in the eDiary 
Plasma glucose (PG) should always be measured by the trial BG meter and hypoglycaemic episodes 
should be recorded in the eDiary.  
The following should be reported in the eDiary as hypoglycaemic events: 
- PG values < 3.9 mmol/L (70 mg/dL) 
- Severe hypoglycaemic episodes without confirmed PG values  
The investigator should ensure correct reporting of the hypoglycaemic episode. Confirmation of the 
hypoglycaemic episode review must be documented in the web portal. In case a subject is not able 
to fill in the eDiary (e.g. in case of hospitalisation) at time of episode, the subject can report the 
episode in the eDiary retrospectively.

If the hypoglycaemic episode fulfils the criteria for an SAE then in addition to the above patient 
reported data, an eCRF AE form and a safety information form must also be filled in. One AE form 
and safety information form can cover several hypoglycaemic values, if the subject has not 
recovered between them and has reported them as one episode in the eDiary. 
Upon onset of a hypoglycaemic episode the subject is recommended to measure PG every 15 
minutes until the PG value is ≥ 3.9 mmol/L (70 mg/dL) and/or symptoms have been resolved in 
accordance with current guidelines38. 
Repeated low PG measurements can be reported by the subject as one hypoglycaemic episode until 
a succeeding PG value is ≥ 3.9 mmol/L (70 mg/dL). In case of several low PG values within the 
hypoglycaemic episode, the lowest value is the one that will be reported as the PG value for the 
hypoglycaemic episode, but the start time of the episode will remain as the time for the first low PG 
value. 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. 
Regarding the question: “To feel better, did you need help to get a sugary drink, food, or 
medicine?” the investigator must instruct the subjects to answer “Yes”, if the episode was an event 
that required assistance of another person to actively administer carbohydrate, glucagon, or take 
other corrective actions. PG concentrations may not be available during an event, but neurological 
recovery following the return of PG to normal is considered sufficient evidence that the event was 
induced by a low PG concentration38. 
eDiary review 
At each contact the investigator should review the eDiary data for correct reporting of PG values 
and hypoglycaemic episodes. In case of incomplete or incorrect data in the eDiary, the subject must 
be questioned whether there have been any severe hypoglycaemic episodes since the last visit. The 
subject shall update the reported data in the eDiary accordingly. 
Re-training of subjects 
The subject 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  
Introduction 
Titration guidelines have been developed, providing recommended dose adjustments at different PG 
levels to ensure that subjects receive an optimal treatment. However, it is recognised that insulin 
treatment 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 subject’s level of glycaemic control, is taken into consideration when decisions on 
dosing are made. The investigator is responsible for the treatment of the subjects and can therefore 
overrule the guidelines to avoid safety hazards. 
Initiation of trial products 
At randomisation eligible subjects will be randomised to receive insulin icodec or insulin degludec. 
• Insulin icodec should be taken once weekly on the same day of the week. All subjects should 
receive a loading dose at randomisation (V2), which consist of total daily basal insulin dose 
before randomisation x 7 + 50% of their total daily basal insulin dose x 7. The following 
weekly dose (V3) should be the total daily dose x 7. In the following table the weekly V2 and 
V3 doses for subjects receiving from 10U to 100U per day have been calculated. Please, note 
that the displayed values are round off to the nearest dose that is dividable by 10.

• Insulin degludec should be taken once daily anytime of the day the same time every day. 
Switching from previous basal insulin should be in accordance with local label. 
• The treat-to-target approach will be applied to both treatment arms to optimise glycaemic 
control throughout the trial. 
• There are no maximum or minimum insulin doses. 
Dose adjustment of trial products during the trial 
After randomisation the investigator should adjust the trial products once weekly in connection with 
the scheduled visits/phone contacts as described below. 
• The dose adjustment will be based on the three pre-breakfast SMPG values measured on two 
days prior to titration and on the day of the contact. 
• If one or more SMPG values are missing, the dose adjustment should be performed on the 
remaining SMPG value(s). 
• The prescribed dose should be determined by the investigator and recorded in the HCP web 
portal.

Deviations from the algorithm 
It is recommended that the algorithm is followed. However, it is also important that the decision to 
adjust insulin doses is based on all relevant information. A reason for deviating from the algorithm 
should be entered the into the HCP web portal by the investigator as applicable. 
Missing insulin icodec dose guidance: 
If an insulin icodec dose is missed for ≤ 3 days after the planned dosing day, subjects should inject 
the planned dose as soon as possible and perform control SMPG measurement. If the missing dose 
is missed for > 3 days, the subject should await the next planned day-of-injection. 
Dose recommendation from end of treatment and during follow up (insulin icodec) 
If it is decided that the individual subject should continue basal insulin after end of treatment, it is 
recommended that the subject is switched from insulin icodec to any available basal insulin at the 
discretion of the investigator. The investigator should instruct the subject in how to switch at the 
“end of treatment” visit (V28).

Regarding the switch from insulin icodec to post-trial basal insulin the following should be 
considered: 
• Calculate the new daily basal insulin dose dividing the latest insulin icodec dose by 7 
• Initiate the new daily basal insulin two weeks after the last injection of insulin icodec 
• 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 insulin icodec 
• Consider titrating the basal insulin once or twice weekly according to the pre-breakfast SMPG 
values and the local label of the chosen insulin. 
Data collection 
The subject should be instructed to report the following in the eDiary: 
• Date, dose and time of insulin degludec or insulin icodec injections 
• Ensure transfer of SMPG values with an indication of “pre-breakfast” or “other” (Section 8.1.1) 
• Hypoglycaemic episodes as described in Appendix 7 (Section 10.7). 
While using the HCP web portal for titration the following will be entered by investigator: 
• Insulin degludec or insulin icodec doses prescribed at this contact. 
• Reasons for deviation from the titration algorithms, if applicable. 
Data surveillance 
Surveillance of titration data will be performed centrally by Novo Nordisk in an unbiased or, if 
possible, a blinded manner. The data will be reviewed and significant deviations from the titration 
algorithm will be followed up.  
It is important that data regarding dose titration is entered into the eDiary and into the HCP web 
portal. Timely registration is crucial in order to take appropriate actions before the subject’s next 
site visit/phone contact. The aim is to reduce the time periods in which a subject may receive 
suboptimal treatment. 
The titration data should be reviewed by Novo Nordisk within 24 hours (on workdays). The 
reviewer may contact the investigator by e-mail or phone 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). 
In addition, Novo Nordisk will monitor changes in HbA1c. Novo Nordisk may visit or phone sites to 
discuss progress in glycaemic control and titration of individual subjects.

10.11 Appendix 11: Protocol amendment history 
The Protocol amendment summary of changes table for the current protocol version is located 
directly before the table of contents. 
Protocol version 2.0 (30 November 2020) 
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 Union1, because 
it neither significantly impacts the safety nor physical/mental integrity of subjects nor the scientific 
value of the trial. 
Overall rationale for preparing protocol, version 2.0: 
The protocol has been amended to allow subjects to co-participate in clinical trials evaluating 
medicinal products for prevention or treatment of COVID-19 disease or postinfectious conditions.  
Section # and name 
Description of change 
Brief rationale

concentration)” and “(anti-insulin 
icodec antibodies)” have been added. 
To make it clear that PK and antibody 
testing are only conducted in the 
insulin icodec arm. 
1.2 Flowchart 
Deleted randomisation visit ”X” for 
hypo-reporting.  
Correction of error (hypo-reporting 
should follow AE reporting). 
2.3.1 Risk assessment 
Added a further COVID-19 related 
mitigation strategy. 
To provide guidance in case of 
COVID-19 related lock down of a site 
or country.
