This amended protocol (amendment 02) is considered to be substantial based on the criteria set 
forth in Article 10(a) of Directive 2001/20/EC of the European Parliament and the Council of the 
European Union.
OVERALL RATIONALE FOR THE AMENDMENT
The protocol is being amended to add an electrocardiogram (ECG) assessment at Week 12, when 
steady state has been achieved, to allow Investigators to assess the effects of efpeglenatide on the 
heart earlier in the study.

and Name
Description of Change
Brief Rationale
Section 1.3 
Schedule of 
Activities (SOA)
An additional ECG assessment will be performed 
at the on-site visit at Week 12
Efpeglenatide is titrated in 2 mg steps every 4 weeks, so 
that the 4 mg dose will be achieved after 4 weeks and the 
6 mg dose after 8 weeks of treatment. Therefore, the 
steady state level of the 6 mg dose will be reached around 
Week 12

PROTOCOL SUMMARY
1.1
SYNOPSIS
Protocol title: A Randomized, Double-blind, Placebo-controlled, Parallel-group, Multicenter 
Study to Evaluate the Effect of Efpeglenatide on Cardiovascular Outcomes in 
Type 2 Diabetes Patients at High Cardiovascular Risk
Short title:
Effect of Efpeglenatide on Cardiovascular Outcomes (AMPLITUDE-O)
Rationale:
The Food and Drug Administration (FDA) requires new therapies for Type 2 Diabetes Mellitus 
(T2DM) to demonstrate that they do not result in an unacceptable increase in cardiovascular (CV) 
risk.  The European Medicines Agency (EMA) reflection paper on assessment of CV safety of 
medical products recommends assessment of CV risk by either a meta-analysis of Phase 3 studies 
or a dedicated cardiovascular outcome trial (CVOT). The present study is a CVOT that has been 
designed to demonstrate the CV safety of efpeglenatide by assessing the noninferiority (NI) of 
efpeglenatide over placebo on 3-point major adverse cardiac events (MACE). If NI is established, 
superiority will also be tested.

Overall design:
This study is a Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group 
study in approximately 4000 T2DM patients at High CV Risk. 
To be eligible for the study, patients must have T2DM with high CV risk and a glycated 
hemoglobin A1c (HbA1c) >7% at screening, and the antihyperglycemic treatment must have been 
stable for 12 weeks prior to randomization, in the opinion of the Investigator.

Prior to randomization, the Investigator will be asked to pre-specify which therapeutic approach 
will be implemented should intensification of the background antihyperglycemic treatment be 
considered necessary during the study.
Patients who meet all eligibility criteria will come back for the randomization visit (Visit 3) and, 
if they are still eligible for the study, they will be randomized 1:1:1 to efpeglenatide 4 mg, 
efpeglenatide 6 mg or placebo. Randomization will be stratified by the current or potential future 
use of a sodium-glucose linked transporter-2 (SGLT2) inhibitor (Current use, Potential future use, 
Neither current nor potential future use). 
Any antihyperglycemic treatment is allowed as background therapy (with the exception of 
glucagon-like peptide-1 [GLP-1] receptor agonists [RAs] and dipeptidyl peptidase-4 [DPP4]
antagonists). For participants with HbA1c <7.5% at time of Screening, and who are treated with 
either insulin, glinide, or sulfonylurea, the doses of the glucose-lowering medications may be 
decreased at Randomization in order to prevent possible hypoglycemia. Antihyperglycemic 
therapy must not be modified for the first 12 weeks after randomization (other than for medical 
necessity). After the first 12 weeks post randomization and during the remaining double-blind 
treatment period, the management of glycemia will be left to the Investigator’s and/or treating 
provider’s judgment, informed by clinical guidelines and local/regional standards of care. 
Investigators will monitor the glycemic status and potassium levels of participants throughout the 
study. If treatment intensification is still considered necessary after dose increase of the 
background antihyperglycemic treatment, the Investigator can prescribe any other 
antihyperglycemic medication (according to its labeling), with the exception of a GLP-1 RA or a 
DPP4 inhibitor, that must not be used during the study.
Participants with a suspected renal event (reduction of eGFR) should have a repeat assessment of 
renal function 30 to 45 days following the onset of the event to confirm it is sustained.
If a participant discontinues treatment with investigational medicinal product (IMP) prematurely, 
the participant will undergo a premature End-of-Treatment (pEOT) Visit, but every effort will be 
made to have the participants return to the site at the time corresponding to their scheduled visits, 
until the end of study. There must be at least 6 weeks of post-treatment safety follow-up between 
the last IMP administration and the Study Closeout Visit for participants who discontinue IMP 
prematurely.
Participants will continue taking IMP after a CV or renal outcome has occurred. If the participant
does not agree to continue taking IMP or to attend site visits, they will be contacted by telephone 
to inquire about safety status (including outcomes).
The study is event driven and will continue until 330 participants have at least one primary event 
(3-point MACE) positively adjudicated by the CEC. At that point all randomized patients have to 
be scheduled to return to the site for a Study Closeout Visit (timing and window will be 
communicated to the sites).
All randomized participants, including those who prematurely discontinued from IMP, will be 
followed from Randomization until the Study Closeout Visit or death, whichever comes first. A

post-treatment safety follow-up visit 6 weeks after the last dose of IMP will be implemented for 
patients still on study treatment at the Study Closeout Visit.
An independent Data Monitoring Committee (DMC) will review clinical study safety data and an 
independent CEC will review, assess and/or adjudicate all events of deaths, selected CV events 
(non-fatal MI, stroke, unstable angina leading to hospitalization, and heart failure leading to 
hospitalization), pancreatic events, and other selected AEs. An independent ophthalmologist 
expert will review in a treatment-blinded manner all reported AEs suspected to be diabetic 
retinopathy to assess the presence of retinopathy and the relationship of reported AE to IMP. See 
Appendix 1 (Section 10.1) for further details of study committees.
Number of participants:
Approximately 4000 patients will be randomly assigned to study intervention to end up with an 
estimated total of 330 participants with at least one positively adjudicated 3-point MACE event.
All randomized participants will be evaluable. See Section 9.2 for details.
Intervention groups and duration:
The study will consist of 3 periods: 

A 2- to 3-week screening period 

A double-blind, placebo-controlled, multiple dose treatment period, including up to 
8 weeks for dose titration 
-
If, at any time during the study, a participant does not tolerate the study treatment, the 
IMP may be temporarily discontinued or if medically necessary, permanently 
discontinued. 
-
If a maximum of 2 (two) consecutive doses are missed, the IMP can be restarted with 
the latest dose given; if 3 or more consecutive doses are missed, the IMP will be 
restarted using a new titration kit. 
-
All IMP discontinuation should initially be considered as temporary unless permanent 
discontinuation is mandated by the protocol.

A follow-up period of 6 weeks after the last dose of IMP
The estimated study treatment duration will be approximately 24 to 36 months, assuming 
approximately 12 months of recruitment, and approximately 24 months of treatment and follow-
up after the last randomized participant.

Analysis of primary objective:
The primary analysis population will be the intent-to-treat (ITT) population that includes all 
randomized participants irrespective of compliance with the study protocol and procedures. 
Participants will be analyzed in the treatment group to which they are randomized.
The time to the first occurrence of the primary composite CV endpoint event (CV death, non-fatal 
MI, or non-fatal stroke) will be analyzed using Cox proportional hazards model with treatment 
(efpeglenatide 4 mg, efpeglenatide 6 mg, placebo), region, and randomization strata of current or 
potential future use of a SGLT2 inhibitor (Current use, Potential future use, Neither current nor 
potential future use) as the covariates. Participants who receive either 4 mg or 6 mg of 
efpeglenatide will be combined as one efpeglenatide treatment group when making comparisons 
using the appropriate contrast for the purposes of the primary analysis. The hazard ratio between

The NI with the 1.8 and 1.3 margin will be demonstrated on the primary endpoint if the upper 
bound (UB) of the two-sided 95% CI is <1.8 and <1.3, respectively.
Kaplan-Meier curves of the cumulative incidence rate will also be provided by treatment groups.
All participants will be followed up to the Study Closeout Visit or death, whichever comes first. 
The primary analysis will be based on the ITT approach that includes events occurring from 
randomization to the end of study, even after the participant has discontinued the study treatment. 
In the ITT approach, all randomized participants will be included and analyzed as randomized. 
The analysis will be based on the positively-adjudicated CV endpoint events. Participants who 
have not experienced any of these primary CV outcomes as positively adjudicated by the CEC 
during the study will be censored at the last date with available information on the CV outcomes 
on or before the study end date for the participant.

Analysis of secondary objectives:
If the NI with the 1.8 and 1.3 margin is demonstrated on the primary endpoint, the superiority of 
pooled efpeglenatide group (4 and 6 mg) vs placebo for the 3-point MACE will be tested in a 
hierarchical fashion.
The two other secondary efficacy endpoints will be analyzed using the same Cox proportional 
hazards model used for the analysis of primary endpoint with treatment (efpeglenatide 4 mg, 
efpeglenatide 6 mg, placebo), region, and randomization strata as the covariates.
The safety analysis will be conducted on the safety population that includes all randomized 
participants who have received at least 1 dose of double-blind treatment, regardless of the amount 
of treatment administered. Participants will be analyzed for safety analyses according to the 
treatment actually received.
All safety summaries will be descriptive; no statistical significance tests will be performed on 
safety data. These analyses will be based on the Safety Population. Treatment-emergent adverse 
events (TEAEs) are defined as AEs that developed or worsened or became serious during the 
period from the administration of first double-blind IMP dose treatments up to 30 days after the 
last administration. 
Each of the two efpeglenatide treatment groups will be compared with the placebo group.
A pre-specified safety analysis will be performed in the subsets of participants on the background 
therapy of metformin + SGLT2, and on metformin + sulfonylurea. Safety summaries will be 
provided by treatment group for each of the subsets, including the summaries for AEs, SAEs, 
deaths, hypoglycemia, AESIs, and AEs requiring specific monitoring.

INTRODUCTION
Efpeglenatide (LAPS-exendin-4, SAR439977, previous code HM11260C), a glucagon-like 
peptide-1 receptor agonist, is a novel long-acting form of CA exendin-4 (an exendin-4 analogue) 
that is being developed for the treatment of adults with T2DM.
2.1
STUDY RATIONALE
In 2008, the FDA issued a guidance requiring new therapies for T2DM to demonstrate that they 
do not result in an unacceptable increase in CV risk (1).  The 2016 EMA reflection paper on 
assessment of CV safety of medical products recommends assessment of CV risk by either a 
meta-analysis of Phase 3 studies or a dedicated CVOT (2).  In this CVOT, CV safety of 
efpeglenatide will be assessed by demonstrating NI of efpeglenatide over placebo on 3-point 
MACE (CV death, non-fatal MI, or non-fatal stroke) at the 1.8 and 1.3 NI margins (UB of the 
2-sided 95% CI) as specified by the 2008 FDA Guidance discussed above.  If NI is established, 
superiority will also be tested.
2.2
BACKGROUND
In recent years, the GLP-1 RA class of pharmacotherapy for T2DM has evolved as an effective 
treatment option from multiple daily injections to daily and then to weekly injections. Glucagon-
like peptide-1 is an endogenous enteroendocrine hormone secreted by L-cells of the distal 
intestine in response to oral nutrient ingestion, and it has multiple physiologic effects that 
contribute to ameliorating hyperglycemia. These effects include enhancing insulin secretion from 
pancreatic β-cells in a glucose dependent manner, suppressing glucagon secretion, and slowing 
gastric emptying. Due to its glucose-dependent mechanism of action, GLP-1 RAs are generally 
associated with a low risk of hypoglycemia.
Glucagon-like peptide-1 RAs exhibit multiple effects across several organ systems, including the 
gastrointestinal (GI), CV, renal and central nervous systems that could decrease the CV risk of 
patients with diabetes. Cardioprotective mechanisms of GLP-1 RAs include weight loss, 
improvement of glucose metabolism, blood pressure (BP) reduction, antiatherogenic properties 
and lipid lowering effects. Glucagon-like peptide-1 RAs are associated with clinically relevant 
weight loss, perhaps via early satiety and delayed gastric emptying, resulting in decreased food 
intake and appetite, without an increase in energy expenditure (3, 4). The adipocyte releases 
regulators of BP and vascular tone, which may influence vasculature, and also myocardial 
ischemia, infarction and contractility. With an injured heart, metabolism shifts toward greater 
oxidation of glucose, rather than free fatty acids (normally 60-90%), due to less oxygen 
consumption. Glucagon-like peptide-1 RAs may increase glucose uptake and facilitate this 
metabolic shift (5). 
Glucagon-like peptide-1 RAs decrease both systolic and diastolic blood pressure (SBP and DBP)
perhaps via a natriuretic/diuretic effect on the kidney, vasodilation and/or decreased sympathetic 
nervous system activity. Glucagon-like peptide-1 receptors are expressed in endothelial cells

vascular smooth muscle cells, monocytes, macrophages and lymphocytes, and therefore, may 
directly affect atherosclerosis, inflammation and may reduce vascular endothelial dysfunction 
(which precedes atherosclerosis) (3, 4). Finally, GLP-1 RAs can lower total cholesterol, LDL, 
fatty acid and triglyceride levels (5).
2.3
BENEFIT/RISK ASSESSMENT
Efpeglenatide is a long-acting GLP-1 RA; it is being developed as an adjunct to diet and exercise 
to improve glycemic control in adults with T2DM.
In 2 Phase 1 and 5 Phase 2 studies, efpeglenatide at doses ranging from 1 to 6 mg weekly and 8 to 
16 mg monthly has been shown to lower blood glucose in participants with T2DM in comparison 
with placebo. A Phase 2 study in obese subjects without diabetes (HM-EXC-205) provided 
evidence for a benefit of efpeglenatide in combination with a hypocaloric diet in terms of body 
weight loss.
HM-EXC-203 and HM-EXC-204, both Phase 2 studies, showed administration of efpeglenatide 
to patients (n=254 and n=209, respectively) with T2DM improved several metabolic parameters 
including HbA1c levels, proportion of patients who had a goal HbA1c level of <7%, LS mean 
changes from baseline in the levels of certain 7-point blood glucose profile parameters, glycated 
albumin levels, and LDL C levels. In addition, decreases from baseline in body weight were 
statistically significantly greater (at least p<0.049 for both) compared to placebo. 
Study HM-EXC-205 was conducted in 295 overweight/obese patients without T2DM.  The 
primary objective of this study was to evaluate the efficacy of efpeglenatide in reducing body 
weight. In this study, 6 mg efpeglenatide administered once weekly for 20 weeks resulted in 
slightly greater weight reduction than what was observed for the 4 mg weekly dose (LS mean 
change from baseline of -7.32 kg [SE 0.63] versus -6.63 kg (SE 0.62), for the 6 and 4 mg weekly 
dose groups, respectively). 
The non-clinical toxicological data and the safety data from clinical studies with efpeglenatide to 
date suggest a safety profile consistent with the known AE profile of currently marketed GLP-1 
RAs, with the exception of potential liver toxicity. Below is a summary of safety findings in all 
Phase I and 2 studies with a data lock date of 22 June 2017.

No major safety concerns were found in the Phase 1 and 2 program of efpeglenatide.

Gastrointestinal AEs, in particular, nausea, were the most common. The trend over time 
for nausea and vomiting events appeared dose related with an increase after the first 
injection, and generally decreasing thereafter. In studies where a titration phase (ie, where 
a schedule of gradual dose escalation up to the randomized dose) occurred, the effect was 
less pronounced during the titration phase. The percent of TEAEs, discontinuations and 
nausea and vomiting appeared to be dose dependent.

There were no reports of pancreatitis.


TEAEs leading to discontinuation in the GI disorders system organ class (SOC) for 
efpeglenatide in Studies HM-EXC-203, HM-EXC-204 and HM-EXC-205 (the large 
Phase 2 studies) were 2.2%, 8.3% and 9.8%, respectively. 

There was one case of medullary thyroid cancer and one case of pancreatic cancer reported 
in the Phase 1 and 2 programs. They were considered by the investigators to be unrelated 
or unlikely related to efpeglenatide respectively.

No serious or severe immunogenicity events (eg, allergic reactions or immune complex 
disease and injection site reactions) were reported. 

No severe hypoglycemia was reported.

No fetal toxicity was reported.

Elevated ALT levels ≥3 x upper limit of normal (ULN) post-baseline were seen in 15 of 
754 subjects in the large Phase 2 studies (HM-EXC-203 and HM-EXC-204 in patients 
with T2DM and HM-EXC-205 in obese subjects); 2 of 147 subjects on placebo, 12 of
571 subjects on efpeglenatide, and 1 of 36 subjects on liraglutide. There were several 
confounding factors such as acetaminophen (paracetamol) used and elevated levels at 
either baseline or screening. None of these subject experienced increased bilirubin 
>2 x ULN. Four of the 15 subjects discontinued study medication due to abnormal liver 
function tests. There were no cases of ALT increase ≥3 x ULN in the Phase 1 studies 
(HM-EXC-101 and HM-EXC-102) and the Phase 2 studies (HM-EXC-201 and 
HM-EXC-202).

Diabetic retinopathy complications have been reported for one of GLP-1 RAs (as of 
05 December 2017). No case has been reported for efpeglenatide. 

The 24-hour ECG performed in Study HM-EXC-102 showed that the increase of heart rate 
(HR) seen with 6 mg efpeglenatide was in the range of liraglutide 1.8 mg.

There were no deaths in the studies.

The SAEs considered related to efpeglenatide included severe dehydration and renal 
failure, in a single subject (6 days after starting efpeglenatide 6 mg QW), possibly caused 
by GI complications (vomiting); and constipation in another patient.
Overall, the potential benefits of efpeglenatide therapy for patients with T2DM, including 
improvement in glycemic control and reduction in body weight, outweigh the potential risks. The 
favorable benefit-risk assessment to date supports the further development. 
The risks to the study participants will be minimized by careful participant selection according to 
appropriate inclusion and exclusion criteria based on existing nonclinical and clinical data. 
During the study participants will be closely monitored at the regular visits, including physical 
examinations and laboratory tests to early detect eventual adverse reactions.
More detailed information about the known and expected benefits and risks and reasonably 
expected adverse events of efpeglenatide may be found in the Investigator’s Brochure (IB) (6).

STUDY DESIGN
4.1
OVERALL DESIGN
This study is a Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group 
study in approximately 4000 T2DM patients at High CV Risk. The study will consist of 3 periods:

A 2- to 3-week screening period 

A double-blind, placebo-controlled, multiple dose treatment period, including up to 
8 weeks for dose titration 
-
If, at any time during the study, a participant does not tolerate the study treatment, the 
IMP may be temporarily discontinued or if medically necessary, permanently 
discontinued. 
-
If a maximum of 2 (two) consecutive doses are missed, the IMP can be restarted with 
the latest dose given; if 3 or more consecutive doses are missed, the IMP will be 
restarted using a new titration kit. 
-
All IMP discontinuation should initially be considered as temporary unless permanent 
discontinuation is mandated by the protocol.

A follow-up period of 6 weeks after the last dose of IMP
The study is event driven and will continue until 330 participants have at least one primary event 
(3-point MACE) positively adjudicated by the CEC.  
To be eligible for the study, patients must have T2DM with high CV risk and an HbA1c >7% at 
screening, and the antihyperglycemic treatment must have been stable for 12 weeks prior to 
randomization, in the opinion of the investigator.
Prior to randomization, the Investigator will be asked to pre-specify which therapeutic approach 
will be implemented should intensification of the background antihyperglycemic treatment be 
considered necessary during the study.
Patients who meet all eligibility criteria will come back for the randomization visit (Visit 3) and, 
if they are still eligible for the study, they will be randomized 1:1:1 to efpeglenatide 4 mg, 
efpeglenatide 6 mg or placebo. Randomization will be stratified by the current or potential future 
use of an SGLT2 inhibitor:

Current use

Potential future use

Neither current nor potential future use
Any antihyperglycemic treatment is allowed as background therapy with the exception of GLP-1 
agonists and DPP4 inhibitors. For participants with HbA1c <7.5% at time of Screening, and who

are treated with either insulin, glinide, or sulfonylurea, the doses of the glucose-lowering 
medications may be decreased at Randomization in order to prevent possible hypoglycemia.
Antihyperglycemic therapy must not be modified for the first 12 weeks after randomization (other 
than for medical necessity). After the first 12 weeks post randomization and during the remaining 
double-blind treatment period, the management of glycemia will be left to the Investigator’s 
and/or treating provider’s judgment, informed by clinical guidelines and local/regional standards 
of care. Investigators will monitor the glycemic status and potassium levels of participants
throughout the study. If treatment intensification is still considered necessary after dose increase 
of the background antihyperglycemic treatment, the Investigator can prescribe any other 
antihyperglycemic medication (according to its labeling), with the exception of a GLP-1 RA or a 
DPP4 inhibitor, that must not be used during the study.
Participants with a suspected renal event (reduction of eGFR) should have a repeat assessment of 
renal function 30 to 45 days following the onset of the event to confirm it is sustained.
If a participant discontinues treatment with IMP prematurely, the participant will undergo a pEOT 
Visit, but every effort will be made to have the participants return to the site at the time 
corresponding to their scheduled visits, until the end of study. There must be at least 6 weeks of 
post-treatment safety follow-up between the last IMP administration and the Study Closeout Visit 
for participants who discontinue IMP prematurely.
Participants will continue taking IMP after a CV or renal outcome occurs. If the participant does 
not agree to continue taking IMP or to attend site visits, they will be contacted by telephone to 
inquire about safety status (including outcomes).
When 330 participants will have at least one primary event (3-point MACE) positively 
adjudicated by the CEC, all randomized participants will be scheduled to return to the site for a 
Study Closeout Visit (timing and window will be communicated to the sites). 
All randomized participants, including those who prematurely discontinued from IMP, will be 
followed from Randomization until the Study Closeout Visit or death, whichever comes first. A 
post-treatment safety follow-up visit 6 weeks after the last dose of IMP will be implemented for 
participants still on study treatment at the Study Closeout Visit.
An independent DMC will review clinical study safety data and an independent CEC will review, 
assess and/or adjudicate all events of deaths, selected CV events (non-fatal MI, stroke, unstable 
angina leading to hospitalization, and heart failure leading to hospitalization), pancreatic events,
and selected AEs. An independent ophthalmologist expert will review in a treatment-blinded 
manner all reported AEs suspected to be diabetic retinopathy to assess the presence of retinopathy 
and the relationship of reported AE to IMP. See Appendix 1 (Section 10.1) for further details of 
study committees.

SCIENTIFIC RATIONALE FOR STUDY DESIGN
Results from 4 CVOTs with GLP-1 agonists (LEADER, ELIXA, SUSTAIN-6 and EXSCEL) 
showed varying effects on cardiovascular outcomes (7, 8, 9, 10). In the LEADER trial liraglutide

significantly reduced the risk of the composite primary endpoint of CV death, non-fatal MI or 
non-fatal stroke by 13% vs placebo (95%CI: 0.78 to 0.97, p=0.01), when added to standard of 
care in patients with T2DM at high CV risk (7). ELIXA showed NI of lixisenatide to placebo 
(hazard ratio=1.02; 95%CI, 0.89 to 1.17) (p for NI <0.001) for the primary outcome of 
cardiovascular death, MI, stroke, or hospitalization for unstable angina after a recent acute 
coronary event (8). SUSTAIN-6 showed that semaglutide was noninferior to placebo on the 
composite primary endpoint of CV death, non-fatal MI (heart attack) or non-fatal stroke (hazard 
ratio=0.74; 95% CI:  0.58 to 0.95; p <0.001) in patients with T2DM at high CV risk. The study 
also showed superiority with p=0.02; however, this analysis was not prespecified in the 
hierarchical testing plan (9).  EXSCEL showed that exenatide was noninferior to placebo on the 
composite primary endpoint of CV death, non-fatal MI or non-fatal stroke in patients with T2DM 
with or without cardiovascular disease (CVD) (hazard ratio, 0.91; 95% CI, 0.83 to 1.00; p <0.001 
for NI) and was not superior (p=0.06 for superiority) (10). The CV effects of the various GLP-1 
RAs in the 4 CVOTs discussed above cannot be directly compared due to differences in study 
design, duration of follow-up, and enrolled patient populations. The ELIXA trial, for example, 
was the only CVOT that investigated the CV effect of a GLP-1 RA in patients with a recent acute 
coronary syndrome. This population with very high CV risk was selected because it should be
ideally suitable for demonstration of CV safety. However, the short duration of follow-up likely 
decreased the ability to detect potential cardioprotective effects of Lixisenatide (8).
In 2015, the EMPA-REG OUTCOME trial showed that the SGLT2 inhibitor empagliflozin, 
reduced the risk of 3-point MACE (CV death, non-fatal MI, or non-fatal stroke) compared to 
placebo (hazard ratio=0.86, p <0.001 NI and p=0.04 for superiority) in patients with T2DM and 
established CV disease (CVD). The CV benefit was primarily driven by a reduction of CV death 
(hazard ratio=0.62, p <0.001) (11). In 2017, the CANVAS program showed that another SGLT2 
inhibitor, canagliflozin, also reduced the risk of 3-point MACE (CV death, non-fatal MI or non-
fatal stroke) by approximately 14% (hazard ratio=0.86; p <0.001 for NI and p=0.02 for 
superiority) in patients with T2DM and established CVD or at high risk for CV events (12). 
Of note, FDA recently approved a new indication for empagliflozin for reducing the risk of CV 
death in adult patients with T2DM and established CVD, and liraglutide for reducing the risk of 
non-fatal stroke, non-fatal MI and CV death in patients with T2DM and established CVD (13, 14).
The EU Summaries of Product Characteristics (SmPCs)  have also been updated to include the 
findings from the empagliflozin and liraglutide CVOT studies (15, 16).
This study is designed to assess the CV effects of efpeglenatide in patients with T2DM and high 
CV risk (see Section 5.1). Therefore it is important to mitigate any potential imbalance between 
the treatment arms in the use of concomitant medications that have been shown to affect the CV 
risk of the patient population. Therapies belonging to two classes of antihyperglycemic 
medications have been shown to be cardioprotective: the GLP1-RAs and the SGLT2 inhibitors. 
Since efpeglenatide is a GLP1-RA, treatment with other GLP1-RA will not be allowed during this
study. Patients will be allowed to participate in this study even if they currently use an SGLT2 
inhibitor, if deemed appropriate based on their comorbid profile. In order to mitigate an imbalance 
in the use of SGLT2 inhibitors, the Investigators will be asked to pre-specify before 
randomization whether they will consider starting an SGLT2 inhibitor should intensification of 
the background antihyperglycemic treatment be considered necessary for a specific patient during 
the study. Both the use at baseline and potential future use of SGLT2 inhibitor will be considered

in the randomization stratification, using the following 3 levels: Current use, Potential future use, 
Neither current nor potential future use. 
The primary analysis will be performed in the ITT population, and all data from randomization to 
the Study Closeout Visit will be included. Patients who start or stop a SGLT2 inhibitor during the 
trial will continue study treatment, will remain in the study and their data will be included in the 
primary analysis. The supportive analysis will include the ITT population with censoring of 
patients at the time of starting or stopping a SGLT2 inhibitor. 
4.3
JUSTIFICATION FOR DOSE
The selection of efpeglenatide 4 and 6 mg once-weekly doses is based on the results of early 
phase studies. Efpeglenatide Phase 2 studies have been conducted in both patients with T2DM as 
well as obese non-diabetic individuals, using a variety of dose regimens including weekly doses 
up to 4 mg (in patients with T2DM) and 6 mg (in non-diabetic overweight/obese patients) as well 
as monthly doses up to 16 mg (T2DM). These studies have demonstrated efpeglenatide’s effect in 
glycemic improvement and weight reduction, with an overall favorable safety and tolerability 
profile.
The once-weekly doses of 4 and 6 mg were chosen for further evaluation based on their HbA1c 
lowering effects and the overall safety observed at these doses. The initial dose will be 2 mg, and 
dose increases to achieve maximum of 6 mg (in the corresponding arm) will be in 2-mg step 
interval every 4 weeks in order to minimize the GI adverse effects. 
Please refer to the IB (6) for more details.
4.4
END OF STUDY DEFINITION
A participant is considered to have completed the study if he/she has completed the Study 
Closeout Visit (in person or by phone) or has died prior to the Study Closeout Visit.
The study is event driven and will continue until it is projected that 330 participants will have at 
least one primary event (3-point MACE) positively adjudicated by the CEC.
All randomized patients will be asked to return to the study site for a Study Closeout Visit when 
approximately 330 participants have at least one primary event (3-point MACE) positively 
adjudicated by the CEC. The timing and window of this visit will be communicated to sites once 
the date on which the required number of events is projected to be positively adjudicated has been 
determined.
For patients who previously prematurely permanently discontinued IMP, the Study Closeout 
Visit, planned at least 6 weeks after the pEOT visit for post-treatment follow-up, will be the final 
study visit. Participants still taking the IMP at the time of the Study Closeout Visit will have their 
final study visit (Follow-up Visit) 6 weeks after their Study Closeout Visit.

SCREEN FAILURES
Screen failures are defined as participants who consent to participate in the clinical study but are 
not subsequently randomly assigned to study intervention. A minimal set of screen failure 
information is required to ensure transparent reporting of screen failure participants to meet the 
Consolidated Standards of Reporting Trials (CONSORT) publishing requirements and to respond 
to queries from regulatory authorities. Minimal information includes demography, screen failure 
details, eligibility criteria, and any SAE.
In cases where a patient fails Screening due to reasons expected to change upon rescreening based 
on the Investigator’s clinical judgment, the patient can be rescreened once. In these cases, the 
patient should be registered as a screen failure in IRT. The patient will then need to sign a new 
ICF, be registered as a rescreen in IRT and assigned a new patient number, and again complete 
Screening Visit procedures/assessments.

SC Injection
Dosing instructions
The injection interval of the IMP is once weekly on the same week day (eg, each 
Monday) at any time of the day.  Injections should be administered SC to the 
abdomen.  Within this region, the site of the injection should be changed 
(rotated) at each time to prevent skin reactions.
Packaging and labeling
Study intervention will be provided in different types of kit boxes. Each kit will be 
labeled as required per country requirement.
INVESTIGATIONAL MEDICINAL PRODUCTS
The appropriate number of kits will be dispensed for the period until the next dispensing visit 
(please refer to SoA in Section 1.3). Storage conditions and use-by-end date (when required by 
country regulations) are part of the label text.
Participants will be trained on the use of the PFS by the study staff at Visit 2 (Week -1) and 
provided with an “instructions for use” leaflet which will describe the handling procedures for the 
PFS and administration technique. The injection training pads can be used, if needed. Initial 
injection technique training at Visit 2 will include mandatory self-injection with a training PFS 
and assessment of participant’s skills and understanding by observing teach-back. If needed, an 
additional training PFS can be used for self-injection technique training any time prior to the day 
of randomization. In some cases, Visit 2 might be combined with Visit 3 (Randomization), as per 
Investigator’s judgement, according to the patient’s medical profile.

Review of injection technique can be done at any other visit as needed. Review of injection sites 
will be performed at all onsite visits. Injections should be administered SC to the abdomen. 
Within this region, the site of injection should be changed (rotated) at each time to prevent skin 
reactions.
Prefilled syringe related issues (malfunctions) should be reported to the Sponsor by the means of a 
procedure on Product Technical Complaint forms, which are described in a separate manual.
Between the protocol-scheduled on-site visits, interim visits may be required for IMP dispensing.

PREPARATION/HANDLING/STORAGE/ACCOUNTABILITY
Investigators or other authorized persons (eg, pharmacists) are responsible for storing the IMP in a 
secure and safe place in accordance with local regulations, labeling specifications, policies, and 
procedures.
Control of IMP storage conditions, especially control of temperature (eg, refrigerated storage) and 
information on in-use stability and instructions for handling the Sanofi compound should be 
managed according to the rules provided by the Sponsor.
The expiry date is mentioned on the IMP labels (when required by country regulation), and 
storage conditions are written on the IMP labels and in the instruction leaflet.
1. The Investigator or designee must confirm appropriate temperature conditions have been 
maintained during transit for all study intervention received and any discrepancies are 
reported and resolved before use of the study intervention.
2. Only participants enrolled in the study may receive study intervention and only authorized 
site staff may supply or administer study intervention. All study intervention must be 
stored in a secure, environmentally controlled, and monitored (manual or automated) area 
in accordance with the labeled storage conditions with access limited to the Investigator
and authorized site staff.
3. The Investigator, institution, or the head of the medical institution (where applicable) is 
responsible for study intervention accountability, reconciliation, and record maintenance 
(ie, receipt, reconciliation, and final disposition records).
4. Further guidance and information for the final disposition of unused study interventions
are provided in a separate study document.
The Investigator, the hospital pharmacist, or other personnel allowed to store and dispense the 
IMP will be responsible for ensuring that the IMP used in the clinical trial is securely maintained 
as specified by the Sponsor and in accordance with applicable regulatory requirements. All IMPs 
will be dispensed in accordance with the Investigator's prescription and it is the Investigator's 
responsibility to ensure that an accurate record of IMP issued and returned is maintained.
Any quality issue noticed with the receipt or use of an IMP/device (deficiency in condition, 
appearance, pertaining documentation, labeling, expiration date, etc) must be promptly notified to

the Sponsor. Some deficiencies may be recorded through a complaint procedure (see 
Section 8.3.8).
A potential defect in the quality of IMP/device may be subject to initiation of a recall procedure 
by the Sponsor. In this case, the Investigator will be responsible for promptly addressing any 
request made by the Sponsor, in order to recall the IMP/device and eliminate potential hazards.
Under no circumstances will the Investigator supply IMP to a third party (except for direct to 
patient shipment, for which a courier company has been approved by the Sponsor), allow the IMP 
to be used other than as directed by this clinical trial protocol, or dispose of IMP in any other 
manner.
6.3
MEASURES TO MINIMIZE BIAS: RANDOMIZATION AND BLINDING
The randomization will be stratified by the current or potential future use of SGLT2 inhibitor 
(Current use, Potential future use, Neither current nor potential future use).
All participants will be centrally assigned to randomized study intervention using IRT. Before the 
study is initiated, instructions on how to access IRT will be provided to each site.
A randomized participant is a participant who has been allocated to a randomized intervention 
regardless whether the intervention kit was used or not. A participant cannot be randomized more 
than once in the study.
Study intervention will be dispensed at the study visits summarized in SoA. 
Returned study intervention should not be re-dispensed to the participants.
The IRT will be programmed with blind-breaking instructions. In case of an emergency, the 
Investigator has the sole responsibility for determining if unblinding of a participant’s treatment 
assignment is warranted. Participant safety must always be the first consideration in making such 
a determination. If a participant’s treatment assignment is unblinded, the Sponsor must be notified 
within 24 hours after breaking the blind. The date and reason that the blind was broken must be 
recorded in the source documentation and case report form, as applicable. When documenting the 
reason for unblinding, the Investigator must not provide any detail regarding the nature of the 
IMP. The Investigator should not divulge IMP detail to the Sponsor’s representative or to any 
staff members until database (DB) closure. Furthermore, when completing forms (eg, AE, SAE, 
adjudication information), the study treatment should not be disclosed on the forms. If the blind is 
broken by the Investigator, the patient must be permanently withdrawn from IMP administration 
but shall continue to be followed in the study.
Methods of blinding
During the double-blind treatment period, which includes titration, Investigators and participants 
will be blinded to the allocation of active or placebo treatment arms. Efpeglenatide and placebo 
will be provided in indistinguishable PFSs, in identical kits. Titration kits differ from treatment 
kits by the number of PFSs inside the kits. Each titration and treatment kit (and the corresponding

syringes) will be labeled with a unique number. The list of kit numbers will be generated by 
Sanofi.
In accordance with the double-blind design, Investigators will remain blinded to study treatment 
and will not have access to the randomization (treatment) codes except under exceptional medical 
circumstances. 
Randomization code breaking will also be performed during the analysis of the ADA samples. 
Only the Project manager and lead scientist at the Bioanalytical laboratory will have access to the 
randomization code to allow for the sorting of the efpeglenatide blood samples. The Bioanalytical 
laboratory and responsible personnel will follow the standard procedures to ensure the protection 
of the blind within the Sponsor’s clinical team. The randomization code or the individual 
analytical results will not be disclosed to any clinical team personnel prior to the DB lock.
Members of the CEC will review and adjudicate events in a blinded manner (please also refer to 
Appendix 1 [Section 10.1]).
The DMC receives unblinded safety data from an independent statistician for review, which will 
be handled strictly confidentially. None of these reports may be delivered to unauthorized persons 
(Appendix 1 [Section 10.1]).
Refer to Section 8.3.4 for suspected unexpected serious adverse drug reaction unblinding by the 
Sponsor.
6.4
STUDY INTERVENTION COMPLIANCE
Measures taken to ensure and document treatment compliance and IMP accountability include:

Proper recording of treatment kit number as required on appropriate electronic case report 
form (e-CRF) page for accounting purposes

All medication treatment kits (whether empty or unused) are returned by the participant at 
each visit when a treatment dispensing is planned

The Investigator or his/her delegate tracks treatment accountability/compliance comparing 
the treatment kit number with the treatment kit number of returned treatment kits (whether 
empty or unused) and fills in the participant treatment log

The monitor in charge of the study then checks the data entered on the IMPs 
administration page of the e-CRF by comparing them with the IMPs that has been 
retrieved and the participant treatment log form
6.5
CONCOMITANT THERAPY
Any medication or vaccine (including over-the-counter or prescription medicines, vitamins, 
and/or herbal supplements) that the participant is receiving at the time of enrollment or receives 
during the study must be recorded along with dates of administration including start and end 
dates.

During the study, the following treatments are prohibited:

Any GLP-1 RA product alone (eg, exenatide, liraglutide, lixisenatide, albiglutide, 
dulaglutide, semaglutide) or in combination

Any DPP-4 inhibitor

Any investigational drug other than IMP for this study
Other medications which are unlikely to interfere with the IMP and the study procedures are 
allowed as needed and have to be recorded in the source data and in the e-CRF. However, doses 
of chronically administered medicines should be kept fixed during the trial if at all possible. 
Glucagon-like peptide-1 receptor agonists are known to decelerate gastric emptying. The delay of 
gastric emptying may impact absorption of concomitantly administered oral medicinal products. 
As drug-drug interaction data are not yet available for efpeglenatide, caution should be exercised. 
Drug levels of oral medications with narrow therapeutic index should be adequately monitored.
During the double-blind study treatment period, the management of glycemia will be left to the 
Investigator’s judgment, informed by clinical guidelines. Investigators will monitor the glycemic 
status and potassium levels of patients throughout the study. For patients with HbA1c <7.5% at 
time of Screening, and who are treated with either insulin, glinide, or sulfonylurea, the doses of 
the glucose-lowering medications may be decreased at Randomization in order to prevent possible 
hypoglycemia. If treatment intensification is still considered necessary after dose increase of the 
background antihyperglycemic treatment, the Investigator can prescribe any other 
antihyperglycemic medication (according to its labeling), with the exception of a GLP-1 RA or a 
DPP4 inhibitor as mentioned above.
6.6
DOSE MODIFICATION
Up-titration of IMP from Randomization to Week 8 is described in Table 1. From Week 8
throughout the rest of the entire double-blind treatment period, participants will remain on the 
randomized IMP dose or placebo until the end of study, except in case of temporary treatment 
discontinuation if, at any time during the study, a participant does not tolerate the study treatment. 
If a maximum of 2 consecutive doses are missed, the IMP can be restarted with the latest dose 
given. In cases of 3 or more missed consecutive doses, the participant will restart treatment using 
a new titration kit (see Section 7.1.2.1). 
6.7
INTERVENTION AFTER THE END OF THE STUDY
The IMPs will not be provided after the end of the treatment period.
When a participant’s participation in the trial ends, the subject will consult with his/her 
Investigator to decide on the best available treatment.

DISCONTINUATION OF STUDY INTERVENTION AND 
PARTICIPANT DISCONTINUATION/WITHDRAWAL 
Withdrawal of consent for treatment (ie, treatment discontinuation at patient request) should be 
distinguished from (additional) withdrawal of consent for follow-up visits and from withdrawal of 
consent for non-patient contact follow-up (eg, medical record checks) follow-up. The site should 
document any case of withdrawal of consent.
7.1
DISCONTINUATION OF STUDY INTERVENTION
The IMP should be continued whenever possible. Patients who report a CV or renal endpoint as 
described in Section 3 should remain on IMP until the end of the study, unless there is a safety 
concern. 
In case the IMP is stopped, it should be determined whether the stop can be made temporarily; 
permanent IMP discontinuation should be a last resort. Any IMP discontinuation must be fully 
documented in the eCRF. In any case, the participant should remain in the study as long as 
possible and followed until study end to collect vital safety status and endpoint data.
7.1.1
Permanent discontinuation of study intervention
Permanent intervention discontinuation is any intervention discontinuation associated with the 
definitive decision from the Investigator not to re-expose the participant to the IMP at any time 
during the study, or from the participant not to be re-exposed to the IMP whatever the reason.
The participants may withdraw from treatment with IMP if they decide to do so, at any time and 
irrespective of the reason. Patients should discuss stopping study medication with the site before
doing so in order that questions can be addressed, concomitant therapy can be adjusted if needed,
and a follow-up assessment arranged. All efforts should be made to document the reasons for
treatment discontinuation and this should be documented in the e-CRF.
A participant should withdraw from treatment with IMP in case of the following:

Intercurrent condition that requires discontinuation of IMP including: 
-
laboratory abnormalities (see decision tree and general guidance for the follow up of 
laboratory abnormalities in Appendix 5 [Section 10.5])
-
diagnosis of acute pancreatitis confirmed by gastroenterologic evaluation and imaging, 
unless a clear cause unrelated to IMP is confirmed and the participant has recovered 
from pancreatitis (see Appendix 6 [Section 10.6])
-
calcitonin value ≥50 pg/mL (see Appendix 6 [Section 10.6])

If, in the Investigator's opinion, continuation with the administration of IMP would be 
detrimental to the participant's well-being


Pregnancy (in female patients)

Confirmed intolerance to the allocated dose of IMP

Any code breaking requested by the Investigator

At the specific request of the Sponsor
See the SoA (Section 1.3) for data to be collected at the time of intervention discontinuation and 
follow-up and for any further evaluations that need to be completed.
Any abnormal laboratory value or ECG parameter will be immediately rechecked for 
confirmation (as soon as possible, preferably within 24 hours) before making a decision of 
permanent discontinuation of the IMP for the concerned participant.
Handling of participants after permanent intervention discontinuation
Every effort should be made to maintain patients in the study. Participants will be followed-up 
according to the study procedures specified in this protocol up to the scheduled date of study 
completion, or up to recovery or stabilization of any AE to be followed-up as specified in this 
protocol, whichever comes last.
If possible, and after the permanent discontinuation of intervention, the participant will undergo a 
pEOT Visit as soon as possible. Participants will then continue in the study with all study 
procedures/visits except those associated with IMP administration. Patients will continue to be 
followed after a CV or renal endpoint occurs irrespective of their treatment status. If the patient 
does not agree to site visits, he/she will be contacted by telephone to inquire about safety status 
(including hospitalizations and endpoints). See the SoA (Section 1.3) for data to be collected at 
the time of intervention discontinuation and follow-up and for any further evaluations that need to 
be completed. 
As all data until the scheduled date of study completion will be used in statistical analyses, it is 
important to collect data for all participants, under treatment or not, during the whole duration of 
the study. A high rate of missing data could jeopardize efficacy results of the study. The 
Investigators should discuss with the participant key visits to attend. The value of critical study 
data collected during the participant’s continued involvement will be emphasized as important to 
the public health value of the study. Site personnel will receive training regarding strategies for 
patient retention, and access to tools to assist with this during the study.
Participants who withdraw from the study intervention should be explicitly asked about the 
contribution of possible AEs to their decision, and any AE information elicited must be 
documented.
All cases of permanent intervention discontinuation must be recorded by the Investigator in the 
appropriate pages of the e-CRF when considered as confirmed.
If after permanent treatment discontinuation, a participant who has discontinued from treatment 
has reconsidered the decision to permanently discontinue treatment and wishes to later resume 
IMP, and if the Investigator has determined there is no safety reason prohibiting the patient from

resuming IMP and the selection criteria for the study are still met, the participant may resume 
IMP with Sponsor approval.
7.1.2
Temporary discontinuation of study intervention
Temporary intervention discontinuation corresponds to at least 1 dose not administered to the 
patient.
If, at any time during the study, a participant does not tolerate the study treatment, the IMP may 
be discontinued. All IMP discontinuation should initially be considered as temporary unless 
permanent discontinuation is mandated by the protocol (see Section 7.1.1), and the Investigator 
should make best effort to resume IMP treatment as early as practically possible. There is no 
defined limit to the duration of temporary discontinuation.
Temporary intervention discontinuation may be considered by the Investigator because of 
suspected AEs. For all temporary intervention discontinuations, duration should be recorded by
the Investigator in the appropriate pages of the eCRF.
7.1.2.1
Rechallenge
Participants who temporarily discontinue IMP should be reassessed at every visit to determine 
whether it is possible to safely resume IMP. Reinitiation of intervention with the IMP will be done 
under close and appropriate clinical/and or laboratory monitoring once the Investigator will have 
considered according to his/her best medical judgment that the responsibility of the IMP(s) in the 
occurrence of the concerned event was unlikely.
If a maximum of 2 consecutive doses are missed, the IMP can be restarted with the latest dose 
given. In cases of 3 or more missed consecutive doses, a new titration kit will be allocated to the 
participant (see Section 6.6).
7.2
PARTICIPANT DISCONTINUATION/WITHDRAWAL FROM THE STUDY
A participant may withdraw from the study at any time at his/her own request, or may be 
withdrawn at any time at the discretion of the Investigator for safety, behavioral, compliance, or 
administrative reasons.
If the participant withdraws consent for disclosure of future information, the Sponsor may retain 
and continue to use any data collected before such a withdrawal of consent.
If a participant withdraws from the study, he/she may request destruction of any samples taken 
and not tested, and the Investigator must document this in the site study records.
See SoA (Section 1.3) for data to be collected at the time of study discontinuation and follow-up 
and for any further evaluations that need to be completed.

If participants no longer wish to take the IMP, they will be encouraged to remain in the study and 
attend the remaining visits (see Section 7.1).
All study withdrawals should be recorded by the Investigator in the appropriate screens of the 
eCRF and in the patient’s medical records. In the medical record, at least the date of the 
withdrawal and the reason should be documented.
If a participant withdraws consent for follow-up, the Investigator should still make best efforts to 
determine the patient’s health status, including at least his/her vital status (including time of 
death), where permitted by local regulations. The patient’s final vital status will be confirmed at 
the time of the study close-out visit.
Participants who have withdrawn from the study cannot be re-randomized (treated) in the study. 
Their inclusion and intervention numbers must not be reused.
7.3
LOST TO FOLLOW UP
A participant will be considered as potential lost to follow-up if he or she repeatedly fails to return 
for scheduled visits and is unable to be contacted by the study site. 
The following actions must be taken if a participant fails to return to the clinic for a required study 
visit:

The site must attempt to contact the participant and reschedule the missed visit as soon as 
possible and counsel the participant on the importance of maintaining the assigned visit 
schedule and ascertain whether or not the participant wishes to and/or should continue to 
take IMP or permanently discontinue IMP while still continuing attend study visits.

Before a participant is deemed potential lost to follow up, the Investigator or designee 
must make every effort to regain contact with the participant (where possible, at least 
3 telephone calls and, if necessary, a certified letter to the participant’s last known mailing 
address or local equivalent methods, contact patient’s family or private physician, review 
available registries, or health care DBs). These contact attempts should be documented in 
the participant’s medical record and continue until DB lock.
The patient informed consent should mention that the study organization including the Sponsor
will make every possible effort to determine this vital status during the scheduled duration of the 
study.

STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarized in the SoA (Section 1.3). Protocol 
waivers or exemptions are not allowed.

Immediate safety concerns should be discussed with the Sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or discontinue 
study intervention.

Adherence to the study design requirements, including those specified in the SoA
(Section 1.3), is essential and required for study conduct.

All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The Investigator will maintain a screening log to 
record details of all participants screened and to confirm eligibility or record reasons for 
screening failure, as applicable. 

Procedures conducted as part of the participant’s routine clinical management (eg, blood 
count) and obtained before signing of the ICF may be utilized for screening or baseline 
purposes provided the procedures met the protocol-specified criteria and were performed 
within the time frame defined in the SoA (Section 1.3).
8.1
EFFICACY ASSESSMENTS
8.1.1
Primary endpoint: 3-point MACE
Cardiovascular death, non-fatal MI and non-fatal stroke events will be adjudicated by the CEC 
(see Appendix 1 [Section 10.1.4.3]).
8.1.2
Secondary efficacy endpoints
All cardiac events (see Section 3) will be adjudicated by the CEC (see Appendix 1 
[Section 10.1.4.3]). 
Renal events (see Section 3) will be reported by the Investigator in the eCRF. Participants with a 
suspected renal event (reduction of eGFR) should have a repeat assessment of renal function 30 to 
45 days following the onset of the event to confirm it is sustained.
8.1.3
Exploratory efficacy endpoint
HbA1c will be measured at different time points during study by a certified level I “National 
Glycohemoglobin Standardization Program” central laboratory.

8.2.1
Physical examinations

A complete physical examination will be performed as per clinical practice in order to 
assess the health status of the participant at Screening and evaluate the inclusion/exclusion 
criteria.

Investigators should pay special attention to clinical signs related to previous serious 
illnesses.

Any new finding or worsening of previous finding should be reported as a new adverse 
event.

Height and body weight will be measured as described in the SoA (see Section 1.3).
8.2.2
Vital signs

Blood pressure and pulse measurements will be assessed in a seated position using the 
same device (automated BP monitor or a manual sphygmomanometer) for each 
participant. 
At the Screening Visit (Visit 1), BP will be measured on both arms to identify and select 
the appropriate arm for future measurements. Seated BP should be measured in both arms 
after at least a 5-minute rest period, and then again after 1 minute in both arms in seated 
position. The arm with the highest systolic BP will be determined at this visit, and BP 
should be measured in this arm throughout the study. This highest value will be recorded in 
the e-CRF.

At subsequent visits, BP and pulse measurements are to be done at participants’ identified 
appropriate arm and should be preceded by at least 5 minutes of rest for the participant in a 
quiet setting without distractions (eg, television, cell phones).

Heart rate will be measured at the time of the measurement of seated BP.
8.2.3
Electrocardiograms

The 12-lead ECG should be performed after at least 10 minutes in supine position and 
prior to other study procedures at that visit (eg, blood collection, IMP administration, etc). 
The Investigator should review the ECG and document the interpretation, sign and date it 
on the ECG print out and report it in the e-CRF. Each ECG trace is analyzed in 
comparison with the Screening ECG. All original ECG traces are kept as source data. The 
ECG assessment of “normal” or “abnormal” will be analyzed.
Note: Any new ECG abnormality should be rechecked for confirmation and reported as an 
AE if considered clinically significant by the Investigator.
8.2.4
Clinical safety laboratory assessments


The Investigator must review the laboratory report, document this review, and record any 
clinically relevant changes occurring during the study in the AE section of the CRF. The 
laboratory reports must be filed with the source documents. Clinically significant 
abnormal laboratory findings are those which are not associated with the underlying 
disease, unless judged by the Investigator to be more severe than expected for the 
participant's condition.

All laboratory tests with values considered clinically significantly abnormal during 
participation in the study should be repeated until the values return to normal or baseline 
or are no longer considered clinically significant by the Investigator or medical monitor.
-
If such values do not return to normal/baseline within a period of time judged 
reasonable by the Investigator, the etiology should be identified and the Sponsor
notified.
All protocol-required laboratory assessments, as defined in Appendix 2 (Section 10.2), must be 
conducted in accordance with the laboratory manual and the SoA.

If local laboratory results are used to make a study treatment decision, for response 
evaluation, or to diagnose/follow-up an AE, then the results must be recorded in the eCRF.

Recommended decision trees for the management of certain laboratory abnormalities are 
provided in Appendix 5 (Section 10.5).
8.2.5
Severe hypoglycemia
The definition of severe hypoglycemia is based on the American Diabetes Association workgroup
on hypoglycemia classification (17, 18): severe hypoglycemia is an event requiring assistance of 
another person to actively administer carbohydrate, glucagon, or other resuscitative actions. These 
episodes may be associated with sufficient neuroglycopenia to induce seizure, unconsciousness or 
coma. Plasma glucose measurements may not be available during such an event, but neurological 
recovery attributable to the restoration of plasma glucose to normal is considered sufficient 
evidence that the event was induced by a low plasma glucose concentration. The definition of 
severe symptomatic hypoglycemia includes all episodes in which neurological impairment was 
severe enough to prevent self-treatment and which were thus thought to place participants at risk 
for injury to themselves or others. Note that “requiring assistance of another person” means that 
the participant could not help himself or herself. Assisting a participant out of kindness, when 
assistance is not required, should not be considered a “requiring assistance” incident.
Severe hypoglycemia will be reported as an AE. Additional information will be recorded 
including symptoms and/or signs, associated glucose value (if available), whether assistance was 
required and the treatment.
Severe hypoglycemia will be qualified as an SAE only if it fulfills SAE criteria (see Appendix 3 
[Section 10.3]). For example, events of seizure, unconsciousness or coma must be reported as 
SAEs.

ADVERSE EVENTS AND SERIOUS ADVERSE EVENTS
Adverse event of special interest
An AESI is an AE (serious or nonserious) of scientific and medical concern specific to the 
Sponsor’s product or program, for which ongoing monitoring and immediate notification by the 
Investigator to the Sponsor is required. Such events may require further investigation in order to 
characterize and understand them. Adverse events of special interest may be added, modified or 
removed during a study by protocol amendment.

Pregnancy of a female subject entered in a study as well as pregnancy occurring in a 
female partner of a male subject entered in a study with IMP (see Section 8.3.5); 

Symptomatic overdose (serious or nonserious) with IMP
-
An overdose (accidental or intentional) with the IMP is an event suspected by the 
Investigator or spontaneously notified by the participant and defined as at least twice 
the planned dose (e.g. two or more injections) if given within 3 days (72 hours).
-
Of note, asymptomatic overdose has to be reported as a standard AE.

ALT ≥3 ULN (if baseline ALT <ULN) Or ALT ≥2 times the baseline value (if baseline 
ALT ≥ULN) (Please refer to related flowchart in Appendix 5 [Section 10.5])
Adverse events requiring specific monitoring
An AE requiring specific monitoring is a serious or non-serious AE of scientific and medical 
concern specific to the Sponsor’s product or program, for which ongoing monitoring may be 
appropriate. Such events may require further investigation to characterize and understand them. 
These events should be reported on the AE page and additional information required on specific 
e-CRF page (where applicable) and will only qualify for expedited reporting when serious 
(fulfilling SAE criteria).
The AE requiring specific monitoring for this study are: 

Severe GI events

Severe hypoglycemia (see Section 8.2.5)

Pancreatic events (including abnormal values of pancreatic enzymes [see Appendix 6, 
Section 10.6])

Calcitonin increase >5.9 pmol/L (20 pg/mL) and thyroid C-cell neoplasm (see Appendix 6, 
[Section 10.6])

Acute renal failure (see Appendix 7 [Section 10.7])

Diabetic retinopathy complications (will be reviewed by an independent ophthalmologist 
expert, see Appendix 1 [Section 10.1.4.4]); a written report from professional eye care 
provider will be required

Severe injection site reactions

Severe allergic reactions


Severe immune complex disease
The definitions of an AE or SAE can be found in Appendix 3 (Section 10.3).
AE will be reported by the participant (or, when appropriate, by a caregiver or surrogate). 
The Investigator and any qualified designees are responsible for detecting, documenting, and 
recording events that meet the definition of an AE or SAE and remain responsible for following 
up AEs that are serious, considered related to the study intervention or study procedures, or that 
caused the participant to discontinue the study intervention (see Section 7). 
Expedited reporting of AE for primary or secondary endpoint is waived (see Section 8.3.7).
8.3.1
Time period and frequency for collecting AE and SAE information 
All SAEs and AEs will be collected from the signing of the ICF until the follow-up visit at the 
time points specified in the SoA (Section 1.3).
All SAEs and AESI will be recorded and reported to the Sponsor or designee within 24 hours, as 
indicated in Appendix 3 (Section 10.3). The Investigator will submit any updated SAE data to the 
Sponsor within 24 hours of it being available.
Investigators are not obligated to actively seek AE or SAE after conclusion of the study 
participation. However, if the Investigator learns of any SAE, including a death, at any time after 
a participant has been discharged from the study, and he/she considers the event to be reasonably 
related to the study intervention or study participation, the Investigator must promptly notify the 
Sponsor.
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).
8.3.2
Method of detecting AEs and SAEs
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and 
non-leading verbal questioning of the participant is the preferred method to inquire about 
AE occurrences. 
8.3.3
Follow-up of AEs and SAEs
After the initial AE/SAE report, the Investigator is required to proactively follow each participant 
at subsequent visits/contacts. At the pre-specified study end-date, all SAEs, non-serious AEs of 
special interest (as defined in Section 8.3), and AEs requiring specific monitoring (as defined in 
Section 8.3) will be followed until resolution, stabilization, the event is otherwise explained, or 
the participant is lost to follow-up (as defined in Section 7.3). Moreover, the ADA levels of 
subjects tested positive at the end of study associated with severe injection site reaction, or 
systemic allergic reaction will be monitored adequately over time up to 6 months from the last 
dose of IMP (see Section 8.8.1).

8.3.4
Regulatory reporting requirements for SAEs

Prompt notification by the Investigator to the Sponsor of a SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of 
a study intervention under clinical investigation are met. 

The Sponsor has a legal responsibility to notify both the local regulatory authority and 
other regulatory agencies about the safety of a study intervention under clinical 
investigation. The Sponsor will comply with country-specific regulatory requirements 
relating to safety reporting to the regulatory authority, Institutional Review Boards 
(IRB)/Independent Ethics Committees (IEC), and Investigators.

Investigator safety reports must be prepared for suspected unexpected serious adverse 
reactions (SUSAR) according to local regulatory requirements and Sponsor policy and 
forwarded to Investigators as necessary.

An Investigator who receives an Investigator safety report describing a SAE or other 
specific safety information (eg, summary or listing of SAEs) from the Sponsor will review 
and then file it along with the IB and will notify the IRB/IEC, if appropriate according to 
local requirements.
8.3.5
Pregnancy

Details of all pregnancies in female participants and female partners of male participants
will be collected after the start of study intervention and until the follow-up visit.

The Investigator may perform additional pregnancy tests at their discretion or as required 
by local regulations.

If a pregnancy is reported, the Investigator should inform the Sponsor within 24 hours of 
learning of the pregnancy and should follow the procedures outlined in Appendix 4 
(Section 10.4).

Pregnancy will be qualified as an SAE only if it fulfills one of the seriousness criteria (see 
Appendix 3 [Section 10.3]).

In the event of pregnancy in a female participant, IMP should be discontinued. 

Follow-up of the pregnancy in a female participant or in a female partner of a male 
participant is mandatory until the outcome has been determined (See Appendix 4 
[Section 10.4])

Abnormal pregnancy outcomes (eg, spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) are considered SAEs.
8.3.6
Cardiovascular and death events
Cardiovascular and death events that are endpoints for the primary and secondary efficacy 
analysis will not be reported according to the standard process for expedited reporting of SAEs 
even though the event may meet the definition of a SAE (see Section 8.3.7).

8.3.7
Disease-related events and other events not qualifying as AEs or SAEs
This study is designed to ascertain whether the following events (primary and secondary 
endpoints) are affected by efpeglenatide:

CV death

Non-fatal MI

Non-fatal stroke

Unstable angina requiring hospitalization

New onset or progression to macro albuminuria (>300 mg/g) accompanied by a UACR 
value increase of ≥30% from Baseline

Sustained ≥40% decrease in eGFR from Baseline (for ≥30 days)

Chronic dialysis (for ≥90 days)

Renal transplant

Sustained eGFR <15 mL/min/1.73 m² (for ≥30 days)
Because these events will be reported and analyzed as efficacy endpoints, they will not be 
reported according to the standard process for expedited reporting of SAEs even though the event 
may meet the definition of a SAE. They are waived from expedited regulatory reporting to Health 
Authorities and they will not be reported to pharmacovigilance except if the Investigator, 
according to his/her best medical judgment, considers these events as related to the IMP taking 
into consideration the patient’s underlying disease. In that case, the Investigator will report it 
within 24 hours to the Sponsor. These events will be recorded on the corresponding CRF page in 
the participant’s CRF within the appropriate time frame. An independent CEC will review and 
adjudicate all events of death, MACE, other selected CV events and other selected AEs. In 
addition, an independent DMC will collect, track and monitor information regarding the 
endpoints. The members, roles and responsibilities of the CEC and DMC will be described in a 
separate charter.
8.3.8
Guidelines for reporting product complaints
Any defect in the IMP/device must be reported as soon as possible by the Investigator to the 
monitoring team that will complete a Product Complaint Form within required timelines.
Appropriate information (eg, samples, labels or documents like pictures or photocopies) related to 
product identification and to the potential deficiencies may need to be gathered. The Investigator
will assess whether or not the quality issue has to be reported together with an AE or SAE.

TREATMENT OF OVERDOSE
Overdose is defined in Section 8.3. 
In the event of an overdose, the Investigator should:
1. Contact the Medical Monitor immediately.
2. Blood glucose levels, HR (telemetry) and liver enzymes should be monitored and 
appropriate supportive treatment should be initiated according to the patient’s clinical 
signs and symptoms.
3. Closely monitor the participant for any AE/SAE and laboratory abnormalities.
4. Document the quantity of the excess dose as well as the duration of the overdose in the 
CRF.
Decisions regarding dose interruptions or modifications will be made by the Investigator in 
consultation with the Medical Monitor based on the clinical evaluation of the participant.

according to the SoA (see Section 1.3). These samples will be tested by the Sponsor or Sponsor's 
designee.
Serum samples will be screened for antibodies binding to efpeglenatide and the titer of confirmed 
positive samples will be reported. Cross-reactivity of confirmed positive samples to endogenous 
GLP-1 (positive/negative), endogenous glucagon (positive/negative), neutralizing capacity of 
ADAs, and presence of anti-polyethylene glycol (PEG) antibodies (positive/negative) will also be

STATISTICAL CONSIDERATIONS 
9.1
STATISTICAL HYPOTHESES
The statistical hypothesis for the primary endpoint of 3-point MACE is to test that efpeglenatide is 
noninferior (1.8 and 1.3 margin) to placebo at the two-sided 5% alpha level:

H0: Hazard ratio of efpeglenatide versus placebo ≥1.8 vs. Ha: Hazard ratio of 
efpeglenatide versus placebo <1.8
and 

H0: Hazard ratio of efpeglenatide versus placebo ≥1.3 vs. Ha: Hazard ratio of 
efpeglenatide versus placebo <1.3
9.2
SAMPLE SIZE DETERMINATION 
It is estimated that approximately 4000 participants are needed to obtain approximately 
330 participants with a positively adjudicated event for the primary composite cardiovascular 
endpoint (3-point MACE), based on the following trial design characteristics assumptions:

a recruitment period of approximately 12 months 

Study duration is estimated to be approximately 24 months of  follow-up after the last 
randomized patient, estimated follow-up ranging from 24 to 36 months

2% annual early study discontinuation

Yearly event rate in placebo group: 4.4% for participants not  using a SGLT2 inhibitor, 
and 3.7% for participants using a SGLT2 inhibitor 

Treatment effect of efpeglenatide compared to placebo: 15% risk reduction for participants 
not using a SGLT2 inhibitor, and  a neutral effect for participants using a SGLT2 inhibitor

20% of participants using a SGLT2 inhibitor at baseline, and additional 10% participants 
in placebo group and 5% participants in efpeglenatide group adding a SGLT2 inhibitor 
during the study period
This will provide:

90% power to demonstrate NI of efpeglenatide vs placebo with a 1.3 NI margin {UB of 
the 95% CI of the estimated hazard ratio <1.3} for the 3-point MACE (CV death, non-fatal 
MI or non-fatal stroke)

>99% power to demonstrate NI with a 1.8 margin

9.4
STATISTICAL ANALYSES
The statistical analysis plan will be developed and finalized before DB lock and will describe the 
participant populations to be included in the analyses, and procedures for accounting for missing, 
unused, and spurious data. This section is a summary of the planned statistical analyses of the 
primary and secondary endpoints.
9.4.1
Efficacy analyses
All efficacy analyses will be performed on the ITT population, unless otherwise specified.
Table 7 - Efficacy analyses
Endpoint
Statistical Analysis Methods
Primary
Time to the first occurrence of any of the 
following clinical events, positively 
adjudicated by the CEC:

CV death

Non-fatal MI

Non-fatal stroke
The time to the first occurrence of the primary composite CV endpoint event (CV 
death, non-fatal MI, or non-fatal stroke) will be analyzed using Cox proportional 
hazards model with treatment (efpeglenatide 4 mg, efpeglenatide 6 mg, placebo), 
region and randomization strata of current or potential future use of a SGLT2 
inhibitor (Current use, Potential future use, Neither current nor potential future 
use) as the covariates. Participants who receive either 4 mg or 6 mg of 
efpeglenatide will be combined as one efpeglenatide treatment group when 
making comparisons using appropriate contrast for the purposes of the primary 
analysis. The hazard ratio between pooled efpeglenatide and placebo will be 
estimated along with the associated two-sided 95%CI.
The NI with the 1.8 and 1.3 margin will be demonstrated on the primary endpoint 
if the UB of the two-sided 95% CI is <1.8 and 1.3, respectively.

Endpoint
Statistical Analysis Methods
Kaplan-Meier curves of the cumulative incidence rate will also be provided by 
treatment groups.
All participants will be followed up to the Study Closeout Visit or death, whichever 
comes first. The primary analysis will be based on the ITT approach that includes 
events occurring from randomization to the end of study, even after the participant
has discontinued the study treatment. In the ITT approach, all randomized 
participants will be included and analyzed as randomized. 
The analysis will be based on the positively-adjudicated CV endpoint events. 
Time to the first occurrence of the primary CV event is the time from 
randomization to the first occurrence of cardiovascular death, non-fatal MI, or 
non-fatal stroke over the duration of the study (ie, randomization to the study end 
date inclusive). Participants who have not experienced any of these primary 
cardiovascular outcomes as positively adjudicated by the CEC during the study 
will be censored at the last date with available information on the CV outcomes on 
or before the study end date for the participant.
If the NI with the 1.8 and 1.3 margin is demonstrated on the primary endpoint, the 
superiority of pooled efpeglenatide vs placebo for the primary endpoint will be 
tested in a hierarchical fashion. The superiority will be claimed if the UB of the 
2-sided 95% CI of hazard ratio is less than 1. The p-value using the log-rank test 
will also be calculated.
Sensitivity analysis:
Sensitivity analyses will also be performed for the primary CV endpoint as 
appropriate, including the analyses that censor the events at the time a participant
starts treatment with a SGLT2 inhibitor (for participants who were not receiving an 
SGLT2 inhibitor at baseline) or stops treatment with a SGLT2 inhibitor (for 
participants who were already receiving an SGLT2 inhibitor at baseline).
Assessment of treatment effect by subgroup:
For the primary composite cardiovascular endpoint, the treatment effects across 
the following subgroup factors will be examined based on ITT population:

Gender (Male, Female)

Age group (<65 and ≥65 years of age).

Race (White, Black or African American, Asian/Oriental, and Other) 
(any race groups with fewer than 5 participants may be combined with 
"Other" category as appropriate).

Ethnicity (Hispanic, Not Hispanic) 

Duration of diabetes categories.

Use of SGLT2 inhibitor at baseline (Yes, No)
The Cox proportional hazards model will be used to estimate the treatment effect 
across the above subgroups, with treatment (efpeglenatide 4 mg, efpeglenatide 
6 mg, placebo), region, randomization strata of current or potential future use of a 
SGLT2 inhibitor (Current use, Potential future use, Neither current nor potential 
future use), subgroup factor, and treatment by subgroup factor interaction as the 
covariates. Hazard ratios between pooled efpeglenatide and placebo for 
categories from a subgroup factor in question will be estimated from this Cox 
model. The corresponding 95% CIs will be provided. Additional subgroups and 
analysis details will be provided in the statistical analysis plan.

The two secondary endpoints will be analyzed using the same Cox proportional 
hazards model as used for the analysis of primary endpoint.  The Cox model will 
include treatment (efpeglenatide 4mg, efpeglenatide 6 mg, placebo), region, and 
randomization strata of current or potential future use of a SGLT2 inhibitor 
(Current use, Potential future use, Neither current nor potential future use) as the 
covariates. The hazard ratio between pooled efpeglenatide and placebo will be 
estimated along with the associated two-sided 95%CI.

9.4.1.1
Multiplicity adjustments
A hierarchical testing procedure will be used for adjustment of multiplicity for the testing of NI 
and superiority on the primary endpoint and in the analysis of the secondary endpoints to strongly 
control the overall Type-1 error rate at 0.05, with the hierarchy defined as:

Non-inferiority (1.8 and 1.3 margin) of efpeglenatide versus placebo on 3-point MACE 
(CV death, non-fatal MI or non-fatal stroke), and then Superiority of efpeglenatide versus 
placebo on 3-point MACE (CV death, non-fatal MI or non-fatal stroke)

Superiority of efpeglenatide versus placebo on time to the first occurrence of the expanded
cardiovascular outcome of cardiovascular death, non-fatal MI, non-fatal stroke, coronary 
revascularization, or  unstable angina

Superiority of efpeglenatide versus placebo on time to the first occurrence of any of the 
following clinical events: new onset or progression to macro albuminuria (>300 mg/g) 
accompanied by a UACR value increase of ≥30% from Baseline, sustained ≥40% decrease
in eGFR from Baseline (for ≥30 days), chronic dialysis (for ≥90 days) , renal transplant,

Safety analyses
All safety analyses will be performed on the Safety Population. 
The observation period of safety data is divided into 3 main segments:

The pre-treatment period is defined as the time from informed consent up to the time of 
the first injection of IMP

The on-treatment period is defined as the time from the first injection of IMP up to 
30 days after the last injection of IMP

The post-treatment period is defined as the time starting 31 days after the last injection of 
IMP (after the on-treatment period)
The AE observations will be classified per the observation periods of safety data as defined above 
into:

Pre-treatment AEs are AEs that developed or worsened or became serious during the 
pre-treatment period

Treatment-emergent AEs are AEs that developed or worsened or became serious during 
the on-treatment period

Post-treatment AEs are AEs that developed or worsened or became serious during the 
post-treatment period.
The primary focus of AE reporting will be on TEAEs. Pre-treatment and post-treatment AEs will 
be described separately.
In addition to the on-treatment period, all AEs, SAEs, AEs leading to permanent treatment 
discontinuation, and AEs leading to death will be summarized for the on-study period, which is 
defined as the time from randomization up to the day of recorded end of study or last contact.

the time of DB lock.
Adverse event incidence tables will be presented by primary SOC (sorted by internationally agreed order), 
HLGT, HLT and PT (sorted in alphabetical order) for each treatment group, showing the number (n) and 
percentage (%) of participants experiencing an AE.
Adverse event incidence table will be provided by treatment group for all types of TEAEs: all TEAEs, all 
treatment emergent SAEs, all TEAEs leading to permanent treatment discontinuation, all TEAEs leading to 
death, all AESI, and AE requiring specific monitoring.
Adverse event incidence table for all types of TEAE will also be provided by treatment group in the subsets 
of participants on the background therapy of metformin + SGLT2, and on metformin + sulfonylurea.

The DMC reviews and analyzes, on a regular basis, unblinded safety data throughout the study, as 
well as safety data from the other ongoing clinical studies conducted with efpeglenatide (a single 
DMC for the whole efpeglenatide program). Details describing the DMC processes and 
procedures are outlined in the DMC Charter. To maintain continuous blinding and study integrity, 
the analysis will be conducted by an independent statistician who will directly transfer data to 
DMC members, and measures will be taken to ensure the validity of the data.
10.1.4.3 Clinical Endpoint Committee
An independent CEC will be composed of experts in the field of cardiology, neurology, and 
gastroenterology (and other appropriate medical specialties as needed). This committee will be 
independent from the Sponsor and the Investigators, and will be implemented to review, assess 
and/or adjudicate all events of death, selected CV events (non-fatal MI, stroke, unstable angina 
leading to hospitalization, and heart failure leading to hospitalization), pancreatic events and other 
selected AEs (to be defined in the CEC charter). This review will be conducted in a blinded 
manner with regard to study treatment.
10.1.4.4 Independent Expert 
An independent ophthalmologist expert will review in a treatment-blinded manner all reported 
AEs suspected to be diabetic retinopathy to assess the presence of retinopathy and the relationship 
of reported AE to IMP.
Investigators are reminded that all patients should have eye examinations based on their 
retinopathy status, performed by a professional eye care provider according to International 
Council of Ophthalmology (ICO) guidelines (19) or local standards. Especially for patients at high 
risk, this should occur at minimum quarterly.
10.1.5 Dissemination of Clinical Study Data
Sanofi shares information about clinical trials and results on publically accessible websites, based 
on company commitments, international and local legal and regulatory requirements, and other 
clinical trial disclosure commitments established by pharmaceutical industry associations. These 
websites include clinicaltrials.gov, European Union clinicaltrialregister (eu.ctr), and sanofi.com, 
as well as some national registries.
In addition, results from clinical trials in patients are required to be submitted to peer-reviewed 
journals following internal company review for accuracy, fair balance and intellectual property. 
For those journals that request sharing of the analyzable data sets that are reported in the

10.1.8 Study and Site Closure
The Sponsor designee reserves the right to close the study site or terminate the study at any time 
for any reason at the sole discretion of the Sponsor. Study sites will be closed upon study 
completion. A study site is considered closed when all required documents and study supplies 
have been collected and a study-site closure visit has been performed.
The Investigator may initiate study-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 study site by the Sponsor 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, the Sponsor's procedures, or GCP guidelines

Inadequate recruitment of participants by the Investigator

Discontinuation of further study intervention development
10.1.9 Publication Policy

The results of this study may be published or presented at scientific meetings. If this is 
foreseen, the Investigator agrees to submit all manuscripts or abstracts to the Sponsor
before submission. This allows the Sponsor to protect proprietary information and to 
provide comments.

The Sponsor will comply with the requirements for publication of study results. In 
accordance with standard editorial and ethical practice, the Sponsor will generally support 
publication of multicenter studies only in their entirety and not as individual site data. In 
this case, a coordinating Investigator will be designated by mutual agreement.

Authorship will be determined by mutual agreement and in line with International 
Committee of Medical Journal Editors authorship requirements.
10.2
APPENDIX 2: CLINICAL LABORATORY TESTS
The tests detailed in Table 9 will be performed by the central laboratory. 


not available in time for either study intervention administration and/or response 
evaluation. If a local sample is required, it is important that the sample for central analysis 
is obtained at the same time. Additionally, if the local laboratory results are used to make 
either a study intervention decision or response evaluation, the results must be entered into 
the CRF.

Protocol-specific requirements for inclusion or exclusion of participants are detailed in 
Section 5 of the protocol.

Additional tests may be performed at any time during the study as determined necessary 
by the Investigator or required by local regulations.

APPENDIX 3: ADVERSE EVENTS: DEFINITIONS AND PROCEDURES FOR 
RECORDING, EVALUATING, FOLLOW-UP, AND REPORTING
DEFINITION OF AE
AE definition

An AE is any untoward medical occurrence in a patient or clinical study participant, 
temporally associated with the use of study intervention, whether or not considered related 
to the study intervention.

NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of study intervention.
Events meeting the AE definition

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or 
other safety assessments (eg, ECG, radiological scans, vital signs measurements), 
including those that worsen from baseline, considered clinically significant in the medical 
and scientific judgment of the Investigator (ie, not related to progression of underlying 
disease).

Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition.

New conditions detected or diagnosed after study intervention administration even though 
it may have been present before the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
intervention or a concomitant medication.

“Lack of efficacy” or “failure of expected pharmacological action” per se will not be 
reported as an AE or SAE. 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 of 
an AE or SAE.
Events NOT meeting the AE definition

Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
Investigator to be more severe than expected for the participant’s condition.

The disease/disorder being studied or expected progression, signs, or symptoms of the 
disease/disorder being studied, unless more severe than expected for the participant’s 
condition.


Medical or surgical procedure (eg, endoscopy, appendectomy): the condition that leads to 
the procedure is the AE.

Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital).

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or 
detected at the start of the study that do not worsen
DEFINITION OF SAE
If an event is not an AE per definition above, then it cannot be an SAE even if serious conditions 
are met (eg, hospitalization for signs/symptoms of the disease under study, death due to 
progression of disease).
A SAE is defined as any untoward medical occurrence that, at any dose:
a) Results in death
b) Is life-threatening
The term 'life-threatening' in the definition of 'serious' refers to an event in which the 
participant 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 hospitalization or prolongation of existing hospitalization
In general, hospitalization signifies that the participant has been detained (usually 
involving at least an overnight stay) 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 hospitalization are AEs. If a 
complication prolongs hospitalization or fulfills any other serious criteria, the event is 
serious. When in doubt as to whether “hospitalization” occurred or was necessary, the AE 
should be considered serious.
Hospitalization for elective treatment of a pre-existing condition that did not worsen from 
baseline is not considered an AE.
d) Results in persistent 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 experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, 
influenza, and accidental trauma (eg, 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)
Other situations:
-
Medical or scientific judgment should be exercised in deciding whether SAE reporting 
is appropriate in other situations such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize

the participant or may require medical or surgical intervention to prevent one of the 
other outcomes listed in the above definition. These events should usually be 
considered serious.
Examples of such events include invasive or malignant cancers, intensive treatment
in an emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug 
dependency or drug abuse.
RECORDING AND FOLLOW-UP OF AE AND/OR SAE
AE and SAE recording

When an AE/SAE occurs, it is the responsibility of the Investigator to review all
documentation (eg, hospital progress notes, laboratory reports, and diagnostics reports) 
related to the event.

The Investigator will then record all relevant AE/SAE information in the CRF.

It is not acceptable for the Investigator to send photocopies of the participant’s medical 
records to the Sponsor’s representative in lieu of completion of the AE/SAE CRF page.

There may be instances when copies of medical records for certain cases are requested by 
the Sponsor’s representative. In this case, all participant identifiers, with the exception of 
the participant number, will be redacted on the copies of the medical records before 
submission to the Sponsor’s representative.

The Investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information. Whenever possible, the diagnosis (not the 
individual signs/symptoms) will be documented as the AE/SAE.
Assessment of intensity
The Investigator will make an assessment of intensity for each AE and SAE reported during the 
study and assign it to 1 of the following categories:

Mild: An event that is easily tolerated by the participant, causing minimal discomfort and 
not interfering with everyday activities.

Moderate: An event that causes sufficient discomfort and interferes with normal everyday 
activities.

Severe: An event that prevents normal everyday activities. An AE that is assessed as 
severe should not be confused with a SAE. Severe is a category utilized for rating the 
intensity of an event; and both AEs and SAEs can be assessed as severe.
An event is defined as ‘serious’ when it meets at least 1 of the predefined outcomes as described 
in the definition of an SAE, NOT when it is rated as severe.
Assessment of causality

The Investigator is obligated to assess the relationship between study intervention and 
each occurrence of each AE/SAE.


A "reasonable possibility" of a relationship conveys that there are facts, evidence, and/or 
arguments to suggest a causal relationship, rather than a relationship cannot be ruled out.

The Investigator will use clinical judgment to determine the relationship.

Alternative causes, such as underlying disease(s), concomitant therapy, and other risk 
factors, as well as the temporal relationship of the event to study intervention
administration will be considered and investigated.

The Investigator will also consult the IB and/or Product Information, for marketed 
products, in his/her assessment.

For each AE/SAE, the Investigator must document in the medical notes 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 to the Sponsor’s representative. However, it is 
very important that the Investigator always make an assessment of causality for 
every event before the initial transmission of the SAE data to the Sponsor’s 
representative.

The Investigator may change his/her opinion of causality in light of follow-up information 
and send a SAE follow-up report with the updated causality assessment.

The causality assessment is one of the criteria used when determining regulatory reporting 
requirements.
Follow-up of AEs and SAEs

The Investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by the Sponsor’s 
representative to elucidate the nature and/or causality of the AE or SAE as fully as 
possible. This may include additional laboratory tests or investigations, histopathological 
examinations, or consultation with other health care professionals.

New or updated information will be recorded in the originally completed CRF.

The Investigator will submit any updated SAE data to the the Sponsor’s representative
within 24 hours of receipt of the information.

Please refer to Section 8.3.3 for more details.
REPORTING OF SAES
SAE reporting to the Sponsor’s representative via an electronic data collection tool

The primary mechanism for reporting an SAE to the Sponsor’s representative will be the 
electronic data collection tool.

If the electronic system is unavailable for more than 24 hours, then the site will use the 
paper SAE data collection tool (see next section).

The site will enter the SAE data into the electronic system as soon as it becomes available.

Page 70

After the study is completed at a given site, the electronic data collection tool will be taken 
off-line to prevent the entry of new data or changes to existing data.

If a site receives a report of a new SAE from a study participant or receives updated data 
on a previously reported SAE after the electronic data collection tool has been taken off-
line, then the site can report this information on a paper SAE form (see next section) or to 
the Sponsor’s representative by telephone.
-
Contacts for SAE reporting can be found in a separate study document.

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 post-menopausal unless 
permanently sterile (see below).
Women in the following categories are not considered WOCBP
1. Premenarchal
2. Premenopausal female with 1 of the following:
-
Documented hysterectomy
-
Documented bilateral salpingectomy
-
Documented bilateral oophorectomy
Note:  Documentation can come from the site personnel’s: review of the participant’s 
medical records, medical examination, or medical history interview.
3. Postmenopausal female
-
A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal 
range may be used to confirm a postmenopausal state in women not using hormonal 
contraception or hormonal replacement therapy (HRT). However, in the absence of 
12 months of amenorrhea, a single FSH measurement is insufficient. 
-
Females on HRT and whose menopausal status is in doubt will be required to use one 
of the non-estrogen hormonal highly effective contraception methods if they wish to 
continue their HRT during the study. Otherwise, they must discontinue HRT to allow 
confirmation of postmenopausal status before study enrollment.

CONTRACEPTION GUIDANCE
Female participants
Female participants of childbearing potential are eligible to participate if they agree to use a 
highly effective method of contraception consistently and correctly as described in Table 10
during the treatment period and for at least 5 weeks after the last dose of study treatment.
In addition, WOCBP must refrain from donating ova for the duration of the study and at least 
5 weeks after last dose of study treatment.


Bilateral tubal occlusion
Vasectomized partner 
A vasectomized partner is a highly effective contraception method provided that the partner is the sole male sexual partner of the 
WOCBP and the absence of sperm has been confirmed. If not, an additional highly effective method of contraception should be 
used.
Sexual abstinence 
Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the 
entire period of risk associated with the study intervention. The reliability of sexual abstinence needs to be evaluated in relation to 
the duration of the study and the preferred and usual lifestyle of the participant.
NOTES: 
a
Typical use failure rates may differ from those when used consistently and correctly. Use should be consistent with local regulations 
regarding the use of contraceptive methods for participants participating in clinical studies. 
b
Pharmacokinetic drug interaction potential of oral hormonal contraception with the study treatment is low, but still unknown. Therefore, if the 
oral contraceptive cannot be replaced by another highly effective method of contraception, with a different route of administration, the 
hormonal contraception method must be supplemented with a male condom (for partner) during the treatment period and for at least 5 
weeks after the last dose of study treatment..

PREGNANCY TESTING:

WOCBP should only be included after a confirmed menstrual period and a negative highly 
sensitive serum pregnancy test.

Additional pregnancy testing should be performed as displayed in the SoA in Section 1.3
and as required locally.

Pregnancy testing will be performed whenever a menstrual cycle is missed or when 
pregnancy is otherwise suspected
COLLECTION OF PREGNANCY INFORMATION:
Male participants with partners who become pregnant 

The Investigator will attempt to collect pregnancy information on any male participant’s 
female partner who becomes pregnant while the male participant is in this study. This 
applies only to male participants who receive IMP.

After obtaining the necessary signed informed consent from the pregnant female partner 
directly, the Investigator will record pregnancy information on the appropriate form and 
submit it to the Sponsor within 24 hours of learning of the partner’s pregnancy. The 
female partner will also be followed to determine the outcome of the pregnancy. 
Information on the status of the mother and child will be forwarded to the Sponsor. 
Generally, the follow-up will be for at least one year following the estimated delivery date. 
Any termination of the pregnancy will be reported regardless of fetal status (presence or 
absence of anomalies) or indication for the procedure. 
Female participants who become pregnant 

The Investigator will collect pregnancy information on any female participant who 
becomes pregnant while participating in this study. Information will be recorded on the 
appropriate form and submitted to the Sponsor within 24 hours of learning of a 
participant's pregnancy. The participant will be followed to determine the outcome of the 
pregnancy. The Investigator will collect follow-up information on the participant and the 
neonate and the information will be forwarded to the Sponsor. Generally, follow-up will 
be for at least one year beyond the estimated delivery date. Any termination of pregnancy 
will be reported, regardless of fetal status (presence or absence of anomalies) or indication 
for the procedure.

Any pregnancy complication or elective termination of a pregnancy will be reported as an 
AE or SAE. A spontaneous abortion is always considered to be an SAE and will be 
reported as such. Any post-study pregnancy related SAE considered reasonably related to
the study intervention by the Investigator will be reported to the Sponsor as described in
Section 8.3.4. While the Investigator is not obligated to actively seek this information in 
former study participants, he or she may learn of an SAE through spontaneous reporting. 

Any female participant who becomes pregnant while participating in the study will
discontinue study intervention

APPENDIX 6: MONITORING AND MANAGEMENT OF PARTICIPANTS WITH 
INCREASED LIPASE AND/OR AMYLASE, OR CALCITONIN
10.6.1 Monitoring of participants with increased lipase and/or amylase >2 ULN
GLP-1 RAs stimulate pancreatic beta-cell and suppress alpha-cell function. Some cases of acute 
pancreatitis have been reported with marketed GLP-1 RAs. Therefore participants enrolled in this 
study should be closely monitored for any suspected pancreatitis, eg, with symptoms and/or signs 
of acute abdominal distress or abnormal levels of pancreatic enzymes. Serum amylase and lipase 
concentrations are monitored routinely at Screening, Baseline and periodically during the study 
treatment period. 
In the presence of clinical signs and/or symptoms evocative of pancreatitis, eg, persistent 
abdominal pain, which can radiate to the back, often with characteristic positional features, with 
possible occurrence of nausea, vomiting, fever and leucocytosis, further measurement of amylase 
and lipase should be performed. The clinical signs and/or symptoms should be documented in the 
source data.
10.6.2 Elevation of amylase and/or lipase >2 x ULN without clinical signs and/or symptoms
In any case where amylase and/or lipase are >2 x ULN, a retest (centrally assessed as far as 
possible) must be performed as follows:

If value(s) is/are >2 to 3 x ULN: retest within 7 days,

If value(s) is/are >3 x ULN: retest within 48 hours,

If the value(s) remain(s) >2 x ULN upon retesting: amylase and/or lipase levels should be 
retested weekly until values are <2 x ULN.
In case a retest is >2 x ULN a gastroenterological evaluation and imaging (ultrasound and/or 
computed tomography [CT] or magnetic resonance imaging [MRI] with contrast, as appropriate) 
must be performed. The absence of clinical signs and/or symptoms should be documented in the 
source documents (if clinical signs and/or symptoms develop, please see Section 10.6.3 below).
Best clinical judgment is to be used when interpreting elevated serum amylase and lipase levels in 
asymptomatic participants. Temporary discontinuation of the IMP may be considered in these 
cases if deemed necessary by the Investigator.
10.6.3 Elevation of amylase and/or lipase >2 x ULN with clinical signs and/or symptoms.
In the presence of clinical signs and/or symptoms evocative of pancreatitis (as described above) 
associated with elevated amylase and/or lipase, treatment with the IMP should be promptly and at 
least temporarily discontinued pending further clinical evaluation and diagnosis confirmation. 
Clinical signs and/or symptoms are to be documented in the source data. A laboratory 
determination of amylase and lipase must be obtained at the time of the event and again within 
48 hours or earlier as clinically indicated. If the value(s) remain(s) >2 x ULN, then amylase and/or

lipase levels should be retested as described in Section 10.6.2 above, or more often if clinically 
indicated.
A gastroenterologic evaluation and imaging (ultrasound and/or CT or MRI with contrast, as 
appropriate) must be performed as clinically indicated and as per clinical practice and local 
guidelines. If a diagnosis of pancreatitis is confirmed, IMP should not be restarted and should be 
permanently discontinued. In both cases as described above under (1) and (2), all laboratory or 
clinical documentations are to be collected. If the retest confirms lipase and/or amylase values are 
>2 ULN , the event must be reported in the e-CRF on the AE form  and the specific 
complementary forms, using the appropriate verbatim: eg, “increased amylase and/or lipase” in 
case of isolated enzyme elevation, “suspected pancreatitis” in the presence of clinical signs 
evocative of pancreatitis if the diagnosis is suspected but cannot be confirmed or excluded, and 
“pancreatitis” if the diagnosis has been confirmed.
10.6.4 Management of participants with increased calcitonin values
During the course of the study if calcitonin value is found ≥20 pg/mL (5.9 pmol/L): 

A retest should be performed by the central laboratory within 7 days. 

The following is to be collected and recorded as soon as possible:
-
Conditions other than C cell disease which may increase calcitonin levels, such as: 
smoking status, treatment with proton-pump inhibitor (eg, omeprazole), autoimmune 
thyroid diseases (Hashimoto’s thyroiditis or Grave’s disease), differentiated thyroid 
cancer, hypercalcemia, hypergastrinemia, chronic renal insufficiency (not on dialysis), 
other neuro-endocrine tumors (lung small cell carcinoma, intestinal carcinoid), acute 
pulmonary inflammatory conditions, or sepsis
-
Personal and/or familial medical history in relation with thyroid or other endocrine 
diseases
-
Specific physical examination (neck, thyroid gland)
If the retest confirms that calcitonin value is ≥20 pg/mL: 

The event must be reported in the e-CRF on the AE form with all appropriate clinical and 
laboratory documentations. 

An ultrasound scan of thyroid should be performed and the participant may be referred to 
a Specialist if judged necessary.

The participant should continue to be followed according to protocol schedule (including 
planned calcitonin measurements). The AE form  should be updated with any new 
information collected during the follow up.

If calcitonin value ≥50 pg/mL (14.75 pmol/L) is found at any time during further follow 
up, the participant should be permanently discontinued from IMP and referred to a 
specialist. As far as possible, blood should be collected 1 to 2 weeks after IMP 
discontinuation and sent to the central laboratory for calcitonin measurement. As per

protocol, the participant should be followed according to study procedures up to the 
scheduled end of the study.
If at any time during follow-up calcitonin value ≥20 pg/mL increases by 20% or more between 
2 assessments (while remaining below 50 pg/mL), a repeated measurement should be performed 
earlier than scheduled in the protocol, ie, 1 month later. Once results are available, discussion with 
Sponsor representative should be initiated without delay for further guidance.
10.7
APPENDIX 7: GUIDANCE FOR THE FOLLOW-UP OF ACUTE WORSENING OF 
RENAL FUNCTION
Rapid change in renal function of greater than 30% as compared with the mean of the prior two 
study visits 

Evaluate if the patient is taking medications which alter serum creatinine such as: 
trimethoprim, fenofibrate, non-steroidal anti-inflammatory agents, cimetidine, 
cephalosporins, probenecid, aminoglycosides, amphotericin, ketoconazole, clofibrate, 
contrast agents

Evaluate if any of the following conditions are present that may alter serum creatinine:
-
Significant increase or decrease in BP due to changes in antihypertensive therapy or 
diuretic treatment
-
Plasma volume depletion or expansion
-
Flu-like symptoms
-
Infected urine
-
Obstructive uropathy
-
New onset or exacerbation of heart failure

If any of the above conditions are met, the Investigator should take corrective measures to 
resolve and schedule an interim visit to evaluate the serum creatinine/GFR and the 
patient’s clinical status 1 week from the institution of corrective measures. Patients with a 
suspected renal event (reduction of eGFR) should have a repeat assessment of renal 
function 30 to 45 days following the onset of the event to confirm it is sustained. If acute 
renal failure is suspected, further clinical evaluation should be performed as per local 
standard of care, including confirmation of renal laboratory parameters, and consideration 
should be given to a nephrology referral. 

Permanent discontinuation of IMP should be a last resort, and if IMP needs to be withheld, 
it should be done so temporarily when possible.

APPENDIX 10: PROTOCOL AMENDMENT HISTORY
The Protocol Amendment Summary of Changes Table for the current amendment is located 
directly before the Table of Contents (TOC).
Amended protocol 01 (28 May 2018)
This amended protocol (amendment 01) is considered to be substantial based on the criteria set 
forth in Article 10(a) of Directive 2001/20/EC of the European Parliament and the Council of the 
European Union.
OVERALL RATIONALE FOR THE AMENDMENT
Health Authorities’ in Canada and Germany requested to update sections related to women of 
childbearing potential (WOCBP) participation, follow-up, and contraception. In addition, Sanofi 
uses this opportunity to edit other sections of the protocol, to update text with new available 
information, to align the procedures with those in other studies within the program and/or for 
better clarity. Main changes are listed below.

Brief Rationale
Section 5.1 
Inclusion 
Criteria and 
Section 10.4 
Appendix 4 
Contraceptive 
guidance and 
collection of 
pregnancy 
information
Clarification of the contraception requirements for 
male and woman of childbearing potential 
(WOCBP): contraception for male participants not 
required, ova donation restrictions added, change 
in contraceptive methods to be used for WOCBP, 
follow-up of pregnancy extended to one year
Efpeglenatide was not genotoxic, and a fertility and early 
embryonic development study in rats revealed no effect 
on male and female fertility and mating performance. 
Furthermore exposure at risk to induce embryo-fetal 
toxicity in female partners of male subjects taking 
efpeglenatide after transfer via seminal fluid can be 
excluded based on an exposure assessment performed 
according to methods proposed by Banholzer et al. (20) 
and an FDA guidance of 2015 (21) based on numerous 
parameters such as exposure at no observed adverse 
effect level (NOAEL) in embryo-fetal studies in two animal 
species, cumulated dose administered vaginally and 
resulting female exposure.  
Using worst case assumptions for these factors a safety 
margin of approximately 1800 between exposure at 
NOAEL in the most sensitive species and estimated 
exposure in females after contamination with 
efpeglenatide via seminal fluid was calculated. Therefore 
use of condoms to avoid this contamination of female 
partners of male subjects taking efpeglenatide is 
considered as not required in clinical trials.
WOCBP use contraception for the duration of the study 
and at least 5 weeks after last dose of study treatment, 
based on the reproductive toxicity profile of efpeglenatide. 
Since the potential fetal toxicity of efpeglenatide can 
extend to ova, WOCBP must refrain from donating ova for 
the duration of the study and at least 5 weeks after last 
dose of study drug (based on half-life of efpeglenatide). 
Contraceptive methods in Table 11 were updated based 
on the clarification that hormonal contraception drug 
interaction potential with the study treatment is low, but 
still unknown. Therefore, if the oral contraceptive cannot 
be replaced by another highly effective method of 
contraception, with a different route of administration, the 
hormonal contraception method must be supplemented 
with a male condom (for partner) during the treatment 
period and for at least 5 weeks after the last dose of study 
treatment. 
The section entitled, “Collection of pregnancy information” 
the duration of follow- up for the pregnancy was extended 
to one year to be consistent with the informed consent 
form (ICF)
Section 8.3.7 
Disease-
related events 
and other 
events not 
qualifying as 
AEs or SAEs
Clarification was added on reporting rules for the 
endpoints when they are considered per 
Investigators as Investigational Medicinal Product

Exclusion 
Criteria
Clarifications on Inclusion Criterion I03 and 
Exclusion Criteria E09, E10, E12, and E14:
I03. Typo error corrected: 9 cardiovascular disease 
criteria instead of 8
E09. Exclusion of patients with hypersensitivity to 
any glucagon-like peptide-1 (GLP-1) receptor 
agonist (RA)
E10. Wording correction, as should state “…within 
6 months prior to randomization” rather than 
“screening”
E12. Clarifications added 
E14. Clarification that prior treatment with GLP1 
RAs is not allowed either alone or in combination
E17 and E21 were removed 
Clarifications for I03 and E10.
E09. Clarification added to exclude the hypersensitivity to 
any GLP-1 RA as well
E12 was amended to provide more details and clarify the
patients’ eligibility criteria.
E14 was amended to clarify that GLP-1 RAs either alone 
or in combination are forbidden as prior treatment. 
E17 was removed since this cardiovascular outcome trial 
(CVOT) is not a glycemic control trial: the addition of 
glucocorticoids will not affect a primary or secondary 
endpoint and therefore is not needed as an exclusion 
criterion. 
E21 was redundant with E24
