1. BACKGROUND AND SIGNIFICANCE: 
 
Patients with type-2 diabetes mellitus (T2D) are often overweight or obese. In order to 
obtain adequate glycemic control, many of these patients require intensive therapy with 
multiple daily injections of insulin (referred to as MDI, basal/bolus regimen), using a rapid- 
acting/bolus insulin at each meal in combination with a once- or twice-daily long- 
acting/basal insulin. Unfortunately, intensive insulin therapy can result in undesired weight 
gain, which may, in part, result in further insulin resistance. In addition, weight gain may 
adversely affect the control of comorbid health conditions (hypertension, hyperlipidemia, 
congestive heart failure, sleep apnea, etc.). The burden of disease management with 
multiple daily injections of insulin also serves as a barrier to A1C goal attainment as 
maintaining compliance with such complex regimens is often challenging in the real-world 
setting. 
 
Once patients with T2D require multiple daily injections of insulin to obtain glycemic 
control, it is generally considered to be a permanent/life-long therapy. However, reports 
have demonstrated the safety and effectiveness of adding once-daily glucagon-like peptide- 
1 receptor agonist (GLP-1RA) liraglutide to basal insulin therapy in order to obtain 
glycemic control (1, 2), and in clinical practice, the addition of liraglutide (or other FDA- 
approved GLP-1RAs) to basal insulin often negates or delays the need to initiate prandial 
insulin. Subsequently, a newer form of anti-diabetic therapy, a once-daily injectable 
combination of GLP-1RA and basal insulin, became available and demonstrated promise 
that perhaps glycemic control may even be obtained with less complex regimens (i.e., less 
daily injections). There are currently two GLP-1RA/basal insulin combination therapies 
that are FDA approved: iGlarLixi (Soliqua®), and iDegLira (Xultophy®) (3, 4). While 
these observations with iGlarLixi and iDegLira demonstrating an improvement in A1C 
while avoiding prandial insulin injections are very exciting, what remains unclear is if 
patients with reasonable glycemic control (A1C ≤ 7.5%) currently receiving MDI 
(basal/bolus, 3-4 injections per day) could potentially maintain or even improve glycemic 
control by switching to a once-daily injectable product like Xultophy® or Soliqua®. 
Currently, there are no studies available (or planned) that have answered this clinical 
question. One limitation of these combination products in the clinical setting is the inability 
to independently titrate the GLP-1RA and basal insulin components. If a patient begins to 
experience hypoglycemia, and/or their fasting BG values are currently within the goal 
range, the dose of these combination products cannot be further titrated, limiting one’s 
ability to further improve glycemic control in patients with a residual A1C elevation. 
 
What also remains unclear is if some of the newer formulations of GLP-1RA may also be 
able to reduce the burden of disease management and maintain glycemic control in patients 
who are currently well-controlled on a regimen of MDI. Recently, subcutaneous (sc) once- 
weekly semaglutide has been demonstrated to be capable of improving glycemic control in 
patients with T2D in combination with insulin therapy. In SUSTAIN-5 (5), at week 30, 
subcutaneous semaglutide 0.5 and 1.0 mg was demonstrated to reduce A1C by 1.4% and 
1.8%, respectively, vs 0.1% with placebo [mean baseline A1C value, 8.4%] in a population 
of T2D patients receiving stable therapy with basal insulin with or without metformin. 
Moreover, mean body weight (kg) decreased with semaglutide 0.5 and 1.0 mg vs placebo 
from baseline to end of treatment: 3.7, 6.4, and 1.4 kg, respectively. Premature treatment 
discontinuation due to adverse events was higher for semaglutide 0.5 and 1.0 mg vs placebo

(4.5%, 6.1%, and 0.8%), mainly due to gastrointestinal disorders. Even if the transition 
from MDI to once-daily sc semaglutide in combination with basal insulin were successful 
in only a minority of patients, the clinical advantage and reduction in burden of disease 
management that would be associated with transitioning from 3-4 injections of insulin per 
day to a regimen of once- weekly sc semaglutide and a once-daily injection of basal insulin 
would be a rather dramatic and remarkable transformation for patients, and one that would 
likely improve patients’ diabetes treatment satisfaction. It would also help to solidify the 
effectiveness and safety of semaglutide in yet another population of patients with T2D. 
What cannot be minimized is the tremendous impact that a successful transition to once-
weekly semaglutide and once- daily basal insulin could have on patients in terms of 
reducing their insulin requirements, assisting with weight loss (or mitigating further weight 
gain), and reducing the frequency and burden of hypoglycemia. In my clinical experience, 
once patients are titrated to full dose GLP-1RA therapy and attain adequate glycemic 
control, insulin doses (particularly prandial insulin) can often be further reduced or 
eliminated without negatively impacting glycemic control. Continuing the insulin therapy 
at higher doses in these patients simply suppresses the glucose-dependent secretion of 
endogenous insulin being promoted by the GLP-1RA therapy. Often, only an abrupt 
cessation of prandial insulin, or a step-wise down- titration of insulin therapy in these 
patients, will reveal that insulin therapy is no longer required at higher doses to maintain 
glycemic control. When this does successfully occur, the impact on patients is 
transformational. 
 
In a recent treat-to-target trial utilizing albiglutide (6), patients with T2D and A1C ≥ 7.0% 
to ≤ 9.5% receiving basal plus prandial insulin (≤ 140 units total daily dose of insulin and 
≤ 70 units of prandial insulin per day) were optimized over 4 weeks before participants 
were randomized (1:1) to albiglutide + optimized basal insulin glargine and lispro (dose 
reduced by 50% at randomization; subsequently, lispro injections were fully discontinued 
4 weeks later) (n=402) or to continued optimized lispro plus optimized glargine (n=412).  
The mean ± SD A1C at baseline was 7.8% ± 0.6% in the albiglutide + glargine group and 
7.7% ± 0.6% in the lispro + glargine group.  The A1C was reduced at week 26 to 6.7% ± 
0.8% and 6.6% ± 0.8%, respectively (least squares [LS] difference 0.06% [95% CI 20.05 
to 0.17]; non-inferiority P < 0.0001).  In the albiglutide + glargine group, 218 participants 
(54%) replaced all prandial insulin without reintroducing lispro up to week 26. Total daily 
prandial insulin dose was similar at baseline but was lower by 62 units/day (95% CI -65.9 
to -57.8; P<0.0001) at week 26 in the albiglutide + glargine group, and the total number of 
weekly injections was also reduced from 29 to 13 per week.  Less severe/documented 
symptomatic hypoglycemia (57.2% vs. 75.0%) occurred in the albiglutide + glargine group 
with meaningful weight differences (LS ± mean SE -2.0 ± 0.2 vs. + 2.4 ± 0.2 kg; P < 
0.0001) vs. lispro + glargine. Gastrointestinal adverse events were higher with albiglutide 
+ glargine (26% vs. 13%). 
 
The results obtained with the transition of uncontrolled patients with T2D receiving MDI 
with albiglutide are encouraging, but would likely have been more robust had a modern 
and more effective long-acting GLP-1RA been utilized.  Unfortunately, 46% of the patients 
randomized to receive albiglutide had to resume prandial insulin prior to week 26 because 
of inadequate glycemic control.  The number of patients that would have been able to fully 
discontinue prandial insulin would have likely been much higher had the patient’s level of 
glycemic control been at target for a longer period of time prior to the transition of the

patient’s prandial insulin to GLP-1RA (i.e., resolution of glucose toxicity), and if a more 
potent and efficacious GLP-1RA, such as once-weekly sc semaglutide, were utilized.  
 
The purpose of this study is to investigate the ability of once-weekly sc semaglutide (in 
combination with once-daily basal insulin) to maintain or improve glycemic control in 
patients currently receiving MDI, while providing the patients with a significant reduction 
in the burden of disease management. In addition, this approach may also furnish a positive 
effect on weight management, a reduction in hypoglycemic episodes, and improvement in 
diabetes treatment satisfaction, when substituted for basal/bolus therapy in patients with 
T2D who currently have adequate glycemic control (A1C ≤ 7.5%) with a regimen of MDI 
(requiring a total of ≤ 80 units of insulin per day). The A1C cut-point of ≤ 7.5% was chosen 
because many patients on complex treatment regimens (MDI) with reasonable control, i.e., 
7-7.5%, would be expected to have a realistic chance of success by switching from MDI to 
sc semaglutide and basal insulin combination therapy. Also, many patients taking complex 
insulin regimens (MDI) fall in the close to A1C goal range of 7-7.5%, so using this cut- 
point, vs. < 7%, would make recruitment easier. Lastly, patients receiving MDI who are 
older and/or with heart disease also have higher individual A1C goal/targets around 7.5%. 
This study will also assess the impact that a successful substitution may have on the 
patients’ diabetes treatment satisfaction, an important, yet under-appreciated aspect of 
diabetes management.

2. SPECIFIC OBJECTIVES: 
 
2.1 The primary overall objectives and specific aims of this project include:  
To determine the ability of once-weekly sc semaglutide in combination with once-daily 
insulin degludec to replace/negate the need for MDI (basal-bolus regimen) in patients 
with T2D under adequate glycemic control (A1C ≤ 7.5%) with MDI, while 
simultaneously providing the patients with a significant reduction in the burden of 
disease management. 
 
2.2 Secondary objectives and specific aims of this project include: 
1) To determine the effect on weight in patients with T2D on MDI transitioned 
from MDI to once-weekly sc semaglutide in combination with once-daily 
insulin degludec. 
2) Record the frequency and severity of hypoglycemia 
3) Assess the impact that a successful substitution may have on a patients’ diabetes 
treatment satisfaction. 
 
3. RESEARCH DESIGN AND METHODS 
 
Study Hypothesis (hypotheses): 
Therapy with once-weekly sc semaglutide in combination with once-daily insulin degludec 
will be capable of maintaining (or improving) glycemic control, when substituted for MDI, 
in patients with T2D with adequate glycemic control (≤ 7.5%) on MDI-based regimens (≤ 
80 units of insulin per day), vs. further titration of insulin therapy in those continuing MDI. 
 
Transitioning MDI to once-weekly sc semaglutide in combination with once-daily insulin 
degludec will be associated with weight loss, less blood glucose confirmed hypoglycemic 
episodes, as well as a reduction the frequency of severe hypoglycemic events, and an 
improvement in diabetes-treatment satisfaction, when compared to continued therapy with 
MDI.

3.2 Study type: 
Study Type: Interventional 
Study Design: Allocation: Prospective, Randomized 
Endpoint Classification: Safety/Efficacy Study 
Intervention Model: Parallel Assignment, Active Comparator 
Masking: Open Label 
Primary Purpose: Treatment 
Number of Treatment Arms: Two 
Duration of Study Period: 26 week active comparator 
 
3.3 Rationale for study Design 
The proposed study design allows for evaluation of glycemic control rates within the 
once-weekly sc semaglutide in combination with once-daily insulin degludec arm, and 
allows for comparison against a control arm. The planned unbalanced randomization 
allows for more precise estimation of these control rates in the primary intervention 
group and also then allows for further evaluation of predictors of glycemic control within 
this group. Randomization provides improved balance on both observed and unobserved 
demographic and clinical factors, minimizing the need to control for covariates in the 
primary analysis. 
 
3.4 Study population:

3.7 Withdrawal Criteria 
The subject may withdraw at will at any time. If a subject has withdrawn their consent, 
the investigator will attempt to bring in the subject for a final study visit to help ensure a 
safe exit from the study. If a subject is difficult to reach for their study visits, three 
attempts will be made to contact the subject (i.e. two phone calls and one written contact). 
If the attempts to contact the subject are unsuccessful, the subject will be withdrawn from 
the study and noted as “lost to follow up”.  
 
Female subjects will be instructed to notify the investigator immediately if they become 
pregnant while participating in the study. Subjects randomized to the once-weekly sc 
semaglutide in combination with once-daily insulin degludec arm that become pregnant 
must discontinue treatment. Following discontinuation of study treatment, subjects will 
be requested to maintain adherence to the study visits. 
3.8 Subject Replacement 
Subjects who have withdrawn their consent to participate will not be replaced. The 
investigator will attempt to bring subjects in for a final study visit. 
 
3.9 Rationale for Study Population 
The rationale used for the selection of the study population was to identify a group of 
patients that would have a reasonable chance of being switched from MDI to once-daily 
sc semaglutide in combination with once-daily insulin degludec without a dramatic 
deterioration in glycemic control. Thus, a population of patients on MDI, with good 
glycemic control on their current regimen was chosen. Good glycemic control is defined 
here as ≤7.5% at baseline (screening). The rationale for selecting ≤ 120 units/day of 
total insulin requirements as an eligibility criterion at baseline was as follows:  
 
  
• At week 26 in the study by Rosenstock et al (6), the patients randomized to 
receive albiglutide + insulin glargine vs. insulin lispro + glargine were receiving 
9.8 ± 17.3 units of prandial insulin vs 71.9 ± 40.1 units, respectively, in addition 
to their basal insulin doses of 59.3 ± 24.1 and 58.6 ± 25.9 units, respectively.  
• The basal and bolus components yielded total daily insulin doses in the 
albiglutide + insulin glargine group of 69.0 ± 33.2 units and 130.4 ± 61.1 units in 
the insulin lispro + insulin glargine group.   
• The prandial insulin dose at week 26 was lower by 62 units/day in the 
albiglutide + insulin glargine group.   
• Thus, one would expect a group of well-controlled patients receiving MDI, ≤ 
120 units of insulin per day, could be controlled on a basal insulin dose on the 
order of 0.5 units/kg (a physiologic approach), and prandial dose ≤ 0.5 
unit/kg/day, plus a highly effective GLP-1RA that could substitute/replace 62 or 
more units of prandial insulin while maintaining glycemic control.  
• Allowing higher doses of insulin, up to 140 units/day, and up to 70 units of 

Version 12: 27 April 2021  
13 
 
prandial insulin per day, as was allowed by Rosenstock et al, may result in a 
failure rate on the order of 50%, as noted in their study where ~50% of patients 
in the albiglutide arm had to resume some prandial insulin prior to week 26.   
• As the primary objective of this study is to demonstrate the ability to maintain 
good glycemic control via switch to sc semaglutide and insulin degludec vs. 
continuing a regimen of MDI, while reducing the patient’s burden of diabetes 
management, a more conservative approach is necessary to avoid the need to 
resume prandial insulin in many of the study subjects prior to week 26.   
 
3.10 Visit Procedures 
The duration of the study visits is anticipated to last 18 months. All visits include a 
window of +/- 7 days. 
 
3.10.1 Screening Visit 
Potential subjects will be screened against the inclusion and exclusion criteria. 
Potentially eligible subjects will be contacted by the study team to introduce the study. 
The screening encounter may occur during a routine visit with their provider or subjects 
may be contacted by telephone. If subjects agree to voluntarily participate, signed 
informed consent will be obtained. 
 
Physical examination will be performed by the study investigator. Gender, age, ethnicity, 
blood pressure, pulse, height, weight, BMI, total daily insulin dose (total, basal and bolus 
components, both in daily units, and as units/kg/day for each component), metformin 
therapy status, SGLT-2 inhibitor therapy status, and the subject’s self-reported duration of 
Type II diabetes will be recorded. 
 
Blood samples will be collected to obtain the following laboratory values: HbA1C, GAD- 
65, serum creatinine and AST/ALT. GAD-65 positive subjects will be excluded from 
continuing in the study. 
 
Subjects can withdraw from the study at any time by notifying their study doctor to 
ensure a safe transition to standard of care therapy. 
 
3.10.2 Randomization Visit 
The randomization visit will occur within 3 weeks of the screening visit. 
 
Weight, BMI, blood pressure, pulse, and total daily insulin dose (basal and bolus) will be 
collected. The study investigator will review screening labs and confirm eligibility of each 
subject before randomization. 
 
To assess the impact that a successful substitution may have on a subject’s diabetes 
treatment satisfaction, the subject will complete the Diabetes Treatment Satisfaction 
Questionnaire Status Version (DTSQs). 
 
Eligible subjects will be randomized 2:1 to either switch to once-weekly sc semaglutide 
in combination with once-daily insulin degludec or continue MDI. Block 
randomization will occur to ensure equal distribution of patients between arms that are 
receiving <80 units of insulin per day and between 80-120 units of insulin per day. 

Version 12: 27 April 2021  
14 
 
Study medications will be dispensed through the Cleveland Clinic Investigational 
Pharmacy. 
 
Patients randomized to continue with MDI will be transitioned from their existing 
regimen to the rapid-acting insulin product insulin aspart and their basal insulin 
switched to once-daily insulin degludec (both provided by the study). This will allow 
for treatment uniformity, and to avoid gaps in treatment that often occur in the real- 
world setting (secondary to insurance copays, deductibles, donut-hold coverage gaps in 
Medicare patients, etc.). Patients randomized to MDI will be allowed to continue 
correction rapid-acting insulin, in addition to their prandial doses of rapid-acting 
insulin, throughout the duration of the study. 
 
In patients randomized to MDI, basal insulin will be adjusted to 0.5 units/kg/day (if their 
pre-trial daily dose of basal insulin is >0.5 units/kg/day, otherwise, if it is ≤ 0.5 
units/kg/day, their current dose will be continued), and the dose of basal insulin will 
continue to be titrated to obtain fasting glucose levels of 70-90 mg/dL as outlined in the 
table below. 
 
 
Their existing doses of prandial insulin, and number of injections, will be continued. Pre- 
meal glucose values of < 130 mg/dL will be targeted, in accordance with the 
recommendations outlined in the ADA Standards of Medical Care in Diabetes-2020 
Position Statement (7). Prandial insulin doses will be increased by 2 unit increments every 
three days (using lowest pre-meal glucose value over the preceding three day period) until 
goal attainment is reached. For example, if the pre-lunch glucose values are consistently 
above range (> 130 mg/dL), the breakfast dose of prandial/rapid-acting insulin will be 
increased by 2 units. The lower limit for pre-prandial blood glucose will be 70 mg/dL. If a 
patient’s lowest pre-meal glucose value over the preceding three days is < 70 mg/dL, the 
prandial insulin dose will be lowered by 2 units. For example, if the pre-lunch glucose 
value is < 70 mg/dL, the breakfast dose of prandial/rapid-acting insulin will be decreased 
by 2 units. See below table. 
 
 
Patients will be asked to check their blood sugar four times daily via point-of-care (POC) 
measures at meals (AC: pre-breakfast, pre-lunch, pre-dinner) and bedtime (HS). These 
values will be used to adjust their insulin regimen, guide dosing of corrective insulin aspart 
and monitor the degree of glycemic control between physician encounters and lab 
assessments. 

Version 12: 27 April 2021  
15 
 
 
 
If hypoglycemia is noted to occur the daily basal insulin degludec dose and total daily 
insulin aspart dose will both be reduced by 10% by the investigator. 
 
The patients randomized to once-weekly sc semaglutide in combination with once-daily 
insulin degludec will start at 0.25 mg of sc semaglutide and adjustment of their dose of 
basal insulin to 0.5 units/kg/day of basal insulin degludec (if their pre-trial daily dose of 
basal insulin is >0.5 units/kg/day, otherwise, if it is ≤ 0.5 units/kg/day, their current dose 
will be continued). Their doses of prandial insulin therapy will be stopped. The dose of 
insulin degludec will be administered once-daily at bedtime, and the dose of once-weekly 
sc semaglutide will be administered on a weekly day of choice determined by the patient. 
Participants assigned to 0.25 mg once-weekly sc semaglutide will undergo dose escalation 
to 0.5 mg at 4 weeks and to the maintenance dose of 1 mg at 8 weeks. The insulin degludec 
dose will remain stable until the patients reach their maximum tolerated dose of sc 
semaglutide. If hypoglycemia is noted to occur during this period, the daily basal insulin 
degludec dose will be reduced by 10% by the investigator. Subsequently, after week 8-12 
(depending on when the patients reach their maximum tolerated dose of once weekly sc 
semaglutide), the lowest fasting blood glucose value over the preceding three day period 
will be used for insulin degludec titration purposes. The target fasting plasma glucose will 
be 70-90 mg/dL. Patients will be instructed on how to self-titrate the insulin degludec and 
will follow the same basal insulin titration algorithm described above. 
 
3.10.3 Semaglutide Dose Titration in Setting of Intolerability/Side Effects 
If a subject does not tolerate (and is unwilling to continue) the 0.25 mg weekly dose of sc 
semaglutide initiated at the randomization visit, it will be stopped until their next study visit. 
If the patient is willing, it will be reinitiated at that the week 4 study visit.  If they once again 
report intolerance that precludes them from continuing, at that time, the sc semaglutide will 
be stopped, and the subject monitored to determine the need for rescue therapy, per protocol.  
 
If a subject does not tolerate the sc semaglutide dose increase from 0.25 mg weekly to 0.5 
mg weekly at week 4 study visit, they will resume the 0.25 mg weekly dose until their week 
8 study visit.  If the subject is tolerating the 0.25 mg weekly dose at the time of the week 8 
study visit, their dose will be increased to 0.5 mg weekly.  If they are tolerating the 0.5 mg 
weekly dose at week 12 study visit, the patient would then continue that dose of sc 
semaglutide and initiate insulin degludec titration.  Further dose escalation of the sc 
semaglutide to 1.0 mg at the week 12 study visit will not be attempted.   
 
If the patient reports not tolerating the 0.5 mg dose (at any point in time after the reattempt 
to increase the dose at the week 8 visit) the subject will be instructed to resume 0.25 mg 
weekly and commence titrating the insulin degludec at that point in time.  They will then 
continue 0.25 mg weekly through the remainder of the study period.   
 
 If a subject does not tolerate the sc semaglutide dose increase from 0.5 to 1.0 mg, initiated 

Version 12: 27 April 2021  
16 
 
at the week 8 study visit, they will be placed back on 0.5 mg weekly and the titration of 
insulin degludec will commence at that point in time (rather than waiting until week 12 
study visit).  
 
At the 12 week follow-up appointment/assessment, the number of daily POC blood glucose 
assessments will be reduced to 1-2 daily measures, per the discretion of the investigator. 
Additional POC assessments may be requested if the investigator feels they are warranted. 
 
The group of patients randomized to sc semaglutide in combination with once-daily basal 
insulin will be allowed to continue correction rapid-acting insulin as described in the table 
above up until the time of their 12 week follow-up appointment/assessment, or until 
achieving their maximum tolerated dose of sc semaglutide, whichever comes first, to help 
address uncontrolled post-prandial hyperglycemia until the dose of sc semaglutide can be 
adequately titrated and maintained. 
 
A failure of once-weekly sc semaglutide in combination with once-daily insulin degludec 
will be defined as a mean daily glucose level consistently > 180 mg/dL despite the 
maximum tolerated dose of sc semaglutide in combination with once-daily insulin degludec 
at a dose greater than 1 unit/kg/day or per the discretion of the investigator. At this point, 
the patients will continue semaglutide but resume prandial insulin for the remaining duration 
of study and titrate according to protocol.

5 ASSESSMENTS: 
 
5.1 Assessments for Efficacy 
Laboratory testing for the protocol indicated HbA1C, GAD-65, serum creatinine and 
AST/ALT will be performed through Cleveland Clinic laboratories. The laboratory 
values will be assessed by the investigator and/or designated study team members. All 
laboratory values will be recorded in the subject’s electronic medical record. All blood 
samples will be collected by the designated study team members and transported to the 
Cleveland Clinic laboratory consistent with clinical procurement and processing methods. 
 
5.2 Assessments for Safety 
All protocol indicated laboratory values will be assessed for clinical significance by the 
investigator and/or designated study team members. 
 
Subject safety and adverse event assessment will occur during each study visit. 
Following randomization, the frequency and severity of hypoglycemia will be assessed at 
each visit. All severe hypoglycemia episodes self-reported by the subject will be 
documented and reported to the Cleveland Clinic Institutional Review Board (IRB) 
consistent with IRB policies and procedures. 
 
A severe hypoglycemic episode is defined as an episode requiring assistance of another 
person to actively administer carbohydrate, glucagon or other corrective action. 
 
In order to ensure participant safety upon completion of the clinical trial, a telephone 
encounter will be conducted on all study subjects, 30 days after study completion. This 
encounter will attempt to ensure patient safety and identify any issues regarding the 
patient’s level of glycemic control post-trial. Any identifiable issues will be addressed by 
the study investigator, in collaboration with the patients other healthcare providers 
(primary care provider, diabetologist, or endocrinologist. 
 
5.3 Other Assessments 
Treatment Satisfaction will also be assessed using the Diabetes Treatment Satisfaction 
Questionnaire Status and Change Versions (8-10). The patients will complete a 
diabetes treatment satisfaction questionnaire DTSQ(s) survey at baseline, and a 
DTSQ(s) and DTSQ(c) at the 26 week visit. 
5.4 Subject Compliance 
Treatment compliance will be assessed by monitoring study medication utilization. 
Subjects will be asked to bring along all used, partially used and unused study 

Version 12: 27 April 2021  
20 
 
medication including empty packaging at each visit. The study team member will assess 
the amounts of study medication used compared to expected usage since the last 
dispensing visit and, in case of discrepancies, question the subject. If a subject is found 
to be non-compliant, the study team member will remind the subject of the importance of 
following the instructions given including taking the study medications as prescribed. 
 
6 STATISTICAL CONSIDERATIONS: 
 
6.1 Sample Size Calculation 
  
We plan to randomize patients 2:1 to sc semaglutide in combination with basal insulin 
degludec or MDI, and anticipate a total sample size of 60 patients.  Sample size 
calculations were performed based on the precision with which differences in control 
rates between groups could be estimated, as well as the within group control rate 
precision. Since the exact glycemic control rate is unknown, calculations were performed 
based on data from Rosenstock et al (2020) where 60% of patients achieved HbA1c 
levels below 7.0% and an estimated 85% achieved levels below 7.5% (under the 
assumption that HbA1c levels were normally distributed).  Based on these assumptions 
and use of a two-sided 95% confidence interval, with 60 patients randomized 2:1, the 
difference in control rates will be able to be estimated to within ± 19% (for pooled 
control rate of 85%) to 26% (with pooled control rate of 60%). With this sample size, the 
control rate with sc semaglutide in combination with basal insulin can be estimated to 
within ±11% to ±15% under the same assumptions for glycemic control rate as above.  
We feel that the gains in precision seen with extra enrollment (>60) do not justify the 
extra resources required to obtain these numbers.

Although identification of risk factors for control with sc semaglutide and once-daily 
basal insulin is an exploratory aim, with this sample size, univariable analyses can be 
performed that will allow for identification of patient characteristics that are associated 
with HbA1c control with sc semaglutide and basal insulin and may warrant future study.   
 
6.2 Statistical Methods 
The primary analysis will be performed using the intent-to-treat cohort. Given the early 
stage of this research, per-protocol analyses among those continuing therapy will also be 
performed to assess efficacy among those who tolerate the therapy. This will help to 

Version 12: 27 April 2021  
21 
 
measure efficacy, in an optimal setting and also perhaps identify subjects where the 
regimen might be most useful in future research. Categorical factors will be described using 
frequencies and percentages, while continuous measures will be summarized using means, 
standard deviations, and percentiles of interest. For the primary outcome, control rates will 
be calculated as proportions, and the difference in control rates with 95% confidence limits 
will be estimated. Categorical variables, including the frequency and severity of 
hypoglycemia, will be compared between groups using Poisson regression models, chi- 
square tests or Fisher exact tests, as appropriate. Relative rates and odds ratios with 95% 
confidence limits will be presented as appropriate. Changes in continuous measures 
between initial and follow-up assessments will be compared using analysis of covariance 
models that include baseline levels of these variables as a covariate. Results will be 
presented as mean levels with 95% confidence limits. If necessary, transformations of 
continuous measures will be performed prior to analysis to meet assumptions of the models. 
The primary endpoint, and all secondary endpoints will be tested assuming an overall 0.05 
significance level. If missing data exists, patterns of missing data will be explored, and if 
appropriate, alternate methods including the use of maximum likelihood estimation in 
mixed effect models or multiple imputation will be explored. Missing data is not expected 
among the primary endpoint, as patients that withdraw from active treatment and do not 
present at the last visit will be classified as failure to control, however assessment of 
missing data patterns will be performed regardless. Frequency tables will be provided to 
identify the reason for control failure (e.g. side effect, lack of efficacy, etc.). Exploratory 
analyses will also be performed to measure the association between patient characteristics 
and glycemic control overall, within assigned groups, and within per protocol groups using 
Pearson chi-square and t-tests to better understand efficacy within the population. 
 
6.3 Interim Analysis 
No interim analysis is planned, as complete enrolment will be necessary for evaluation of 
exploratory goals of the study. 
 
6.4. Explorative Statistical Analysis for Pharmacogenetics and Biomarkers 
Not planned for this study. 
 
7 DATA HANDLING AND RECORD KEEPING: 
 
A file database will be created for data collection accessible only by authorized study 
personnel. Information will be entered into the database as it is collected and patients finish 
the study. Each patient will be assigned a study number consecutively as they are enrolled. 
Only the study number will be used to identify all study-related documents such as case 
report forms. A master list of study numbers linked to patient identifiers will be maintained 
by the study coordinator in a secured location. Study data will be collected and managed 
using REDCap (Research Electronic Data Capture); this will include patient identification 
number, medical record number, age, gender, and ethnicity. 
 
If a subject withdraws from the trial or is lost to follow-up, then the subject’s data which 
has already been collected will be retained by the investigator, entered into the database 
and used for the study reporting. 
 
8 ETHICS:

11. CONCOMITANT ILLNESSES AND MEDICATIONS: 
 
Definitions: 
Concomitant illness: any illness that is present at the start of the trial (i.e. at the first visit). 
Concomitant medication: any medication other than the trial product(s) that is taken during 
the trial, including the screening period will be recorded. Details of all concomitant 
illnesses and medication will be recorded at trial entry (i.e. at the first visit). Any changes in 
concomitant medication will be recorded at each visit. If the change 
influences the subject’s eligibility to continue in the trial, the Sponsor will be informed. 
 
The information collected for each concomitant medication will include start date, stop 
date or continuing, and indication. For each concomitant illness, date of onset, date of 
resolution or continuing, will be recorded

Version 12: 27 April 2021  
24 
 
 
12. ADVERSE EVENTS: 
 
The investigator will be responsible for reporting of all adverse events including serious 
adverse events (SAE), suspected unexpected serious adverse reactions (SUSARs), serious 
adverse drug reactions (SADRs) to the Cleveland Clinic institutional review board based 
upon federal regulations and local/IRB policies and procedures. The sponsor-investigator 
will also report to Novo Nordisk all SAEs, SUSARs, and SADRs at the same time such 
events are reported to regulatory authorities or within 15 days from the sponsor- 
investigator becoming aware of such adverse events, whichever comes first. 
 
12.1 Definitions 
 
12.1.1 Adverse Event (AE): 
An AE is any undesirable medical event occurring to a subject in a clinical trial, whether 
or not related to the trial product(s). This includes events reported from the first trial 
related activity after the subject has signed the informed consent and until post treatment 
follow-up period as defined in the protocol. The following should not be recorded as AEs, 
if recorded as medical history/concomitant illness on the CRF at screening: 
• Pre-planned procedure, unless the condition for which the procedure was planned has 
worsened from the first trial related activity after the subject has signed the informed 
consent 
• Pre-existing conditions found as a result of screening procedures 
 
12.1.2 Clinical Laboratory Adverse Event: 
A clinical laboratory AE is any clinical laboratory abnormality regarded as clinically 
significant i.e. an abnormality that suggests a disease and/or organ toxicity and is of a 
severity, which requires active management, (i.e. change of dose, discontinuation of trial 
product, more frequent follow-up or diagnostic investigation). 
 
12.1.3 Serious Adverse Event (SAE): 
A serious AE is an experience that at any dose results in any of the following: 
• Death 
• A life-threatening* experience 
• In-patient hospitalisation or prolongation of existing hospitalization 
• A persistent or significant disability/incapacity 
• A congenital anomaly/birth defect 
• Important medical events that may not result in death, be life-threatening*, or require 
hospitalization may be considered an SAE when, based upon appropriate medical 
judgement, they may jeopardise the subject and may require medical or surgical 
intervention to prevent one of the outcomes listed in this definition 
• Suspicion of transmission of infectious agents 
*The term life-threatening in the definition of SAE refers to an event in which the subject 
was at risk of death at the time of the event. It does not refer to an event which 
hypothetically might have caused death if it was more severe. 
 
12.1.4 Serious Adverse Drug Reaction (SADR): 

Version 12: 27 April 2021  
25 
 
An adverse drug reaction (ADR) is an adverse event (AE) for which a causal relationship 
to the trial product is at least possible i.e. causal relationship is conceivable and cannot be 
dismissed. Serious adverse reaction (SAR): Adverse event which fulfils both the criteria 
for a Serious Adverse Event and the criteria for an Adverse Reaction. 
 
12.1.5 Suspected Unexpected Serious Adverse Reaction (SUSAR): 
An SAE which is unexpected and regarded as possibly or probably related to the 
trial/study product by the investigator. The current approved summary of 
product characteristics (package insert) for Ozempic® will be used for 
assessment of expectedness. 
 
12.1.6 Medical Events of Special Interest (MESI): A MESI is (1) a medication error 
(e.g. wrong drug administration or wrong route of administration) or (2) a suspected 
transmission of an infectious agent via the product 
 
12.1.7 Non-Serious Adverse Event: 
A non-serious AE is any AE which does not fulfil the definition of an SAE. 
 
12.1.8 Severity Assessment Definitions: 
• Mild: Transient symptoms, no interference with the subject’s daily activities 
• Moderate: Marked symptoms, moderate interference with the subject’s daily activities 
• Severe: Considerable interference with the subject’s daily activities, unacceptable 
 
12.1.9 Relationship to study medication Assessment Definitions: 
• Probable: Good reasons 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 an etiology other than the trial product 
 
12.1.10 Outcome Categories and Definitions: 
• Recovered: Fully recovered or by medical or surgical treatment the condition has 
returned to the level observed at the first trial related activity after the subject signed the 
informed consent 
• Recovering: The condition is improving and the subject is expected to recover from the 
event. This term should only be used when the subject has completed the trial 
• Recovered with sequelae: As a result of the AE, the subject suffered persistent and 
significant disability/incapacity (e.g. became blind, deaf, paralysed). Any AE recovered 
with sequelae should be rated as an SAE 
• Not recovered 
• Fatal 
• Unknown 
 
12.1.11 Collection, Recording and Reporting of Adverse Events 
All events meeting the definition of an adverse event must be collected and reported from 
the first trial related activity after the subject has signed the informed consent and until 
the end of the posttreatment follow-up period as stated in the protocol. At a minimum, 
the following information will be collected: study name, subject study ID number, age, 
sex, event (diagnosis), trial drug, causality, outcome, and reporter.

12.1.12 Follow-up of Adverse Events 
During and following a subject’s participation in a clinical trial, the sponsor-investigator 
and institution will provide adequate medical care to the study subject for any study- 
related adverse events, including clinically significant laboratory values related to the 
study. Medical care for study subjects will be provided regardless of their insurance 
status. 
 
All adverse events classified as serious or severe or possibly/probably related to the trial 
product must be followed until the subject has recovered and all queries have been 
resolved. For cases of chronic conditions follow-up until the outcome category is 
“recovered” is not required, as these cases can be closed with an outcome of “recovering” 
or “not recovered”. 
 
All other adverse events must be followed until the outcome of the event is “recovering” 
(for chronic conditions), or “recovered” or until the end of the post-treatment follow-up 
stated in the protocol, whichever comes first, and until all queries related to these AEs 
have been resolved. 
 
12.1.13 Pregnancy 
 
Female subjects of childbearing potential must use adequate contraceptive methods until 
4 weeks after the last dosage of Ozempic®. 
 
Study subjects will be instructed to notify the investigator immediately if they become 
pregnant. 
 
The investigator will report to Novo Nordisk any pregnancy occurring during the trial 
period. Reporting of pregnancy by the investigator will occur within the same timelines 
described above for reporting of Adverse Events. 
 
Pregnancy complications should be recorded as adverse event(s). If the infant has a 
congenital anomaly/birth defect this must be reported and followed up as a serious 
adverse event. 
 
12.1.14 Precautions/Over-dosage 
Include information concerning precautions and procedures to be observed in the event of 
overdose by any trial product provided during the study. 
13. LIABILITY AND SUBJECT INSURANCE: 
During and following a subject’s participation in trial, the sponsor-investigator and 
his/her institution will provide adequate medical care to the study subject for any study- 
related adverse events, including clinically significant laboratory values related to the 
study. Medical care for study subjects will be provided regardless of their insurance 
status. 
 
The Cleveland Clinic will indemnify, defend and hold harmless Novo Nordisk, including 
its affiliates or subsidiaries, and their respective officers, directors and employees for any 
claims, suits, actions, proceedings and related costs and expenses, and all damages, costs, 

Version 12: 27 April 2021

penalties, and expenses, including reasonable attorneys’ fees directly related to The 
Cleveland Clinic’s negligence, willful misconduct or illegal activity in the conduct of the 
study, except to the extent that such covered claims are due to the negligence or willful 
misconduct of Novo Nordisk or its agents in performing Novo Nordisk’s obligations 
under this study and/or claims arising from a personal injury to a study subject to the 
extent directly caused by a manufacturing defect of Novo Nordisk’s study products. 
 
14. PREMATURE TERMINATION OF STUDY: 
Novo Nordisk, the sponsor-investigator, the Cleveland Clinic IRB or a regulatory 
authority may decide to stop the trial or part of the trial, but an agreement from all parties 
on the procedures to be followed will first be obtained. 
 
If the trial is suspended or prematurely terminated, the sponsor-investigator will inform 
the study subjects to ensure a safe withdrawal. The sponsor-investigator will promptly 
inform Novo Nordisk, the Cleveland Clinic IRB and regulatory authorities. 
 
15. PUBLICATION PLAN: 
Upon study completion, the data generated will be submitted in abstract form to the next 
eligible session of the annual American Diabetes Association National Meeting, and 
subsequently submitted to Diabetes Care for publication consideration. 
 
The sponsor-investigator will plan to register the study with clinicaltrials.gov.
