Objective 
The objective of this trial is to evaluate safety of 3-month dual 
antiplatelet therapy (DAPT) in subjects at high risk of bleeding 
(HBR) undergoing percutaneous coronary intervention (PCI) with 
XIENCE.  
 
Primary Objective: to show non-inferiority of the primary endpoint 
of all death or all MI (modified ARC) from 3 to 12 months following 
XIENCE implantation in HBR subjects treated with 3-month DAPT 
compared to a historical control after propensity score adjustment.  
Secondary Objective:  
• To show superiority of the major secondary endpoint of major 
bleeding (Bleeding Academic Research Consortium [BARC] 
type 2-5) from 3 to 12 months following XIENCE implantation 
in HBR subjects treated with 3-month DAPT compared to a 
historical control after propensity score adjustment.  
• To evaluate stent thrombosis (ARC definite/probable) from 3 to 
12 months following XIENCE implantation in HBR subjects 
treated with 3-month DAPT against a performance goal (PG). 
Targeted Number 
of Subjects  
Approximately 2,000 subjects from approximately 100 sites 
globally, with at least 50% of subjects in the United States. Subject 
registration is capped at 300 per site.  
Clinical Trial 
Design 
A prospective, single arm, multi-center, open label, non-randomized 
trial to evaluate the safety of 3-month DAPT in HBR subjects 
undergoing PCI with XIENCE.  
Primary Endpoint The primary endpoint is a composite rate of all death or all 
myocardial infarction (modified 4Academic Research Consortium 
[ARC]) from 3 to 12 months. 
Major Secondary 
Endpoints  
• Major bleeding rate (BARC type 2-5) from 3 to 12 months. 
• Stent thrombosis (ARC definite/probable) from 3 to 12 months 
Secondary 
Endpoints 
The following endpoints will be assessed from 3 to 12 months: 
• All death, cardiac death, vascular death, non-cardiovascular death 
 
 
 
 
 
4 Patients present any of the following clinical or imaging evidence of ischemia (symptoms of ischemia;  ECG 
changes  indicative of new ischemia -  [new ST-T changes or new LBBB],  development of pathological Q 
waves;  or  imaging evidence of a new loss of  viable myocardium or a new regional wall  motion abnormality), 
AND confirmed with elevated cardiac biomarkers  per ARC criteria  (periprocedural MI: CK-MB > 3x URL or 
Troponin > 3x URL within 48 hours after PCI; CK-MB > 5x URL or Troponin > 5x URL within 72 hours after 
CABG; Assessment of CK-MB is preferred over troponin for the diagnosis of periprocedural MI, if possible. 
For spontaneous MI: CK-MB > URL or Troponin > URL) (Circulation 2007; 116: 2344-2351)  

Abbott Vascular 
Version 3.0

• All myocardial infarction (MI) and MI attributed to target vessel 
(TV-MI, modified ARC) 
• Composite of cardiac death or MI (modified ARC) 
• All stroke, ischemic stroke and hemorrhagic stroke  
• Clinically-indicated target lesion revascularization (CI-TLR)  
• Clinically-indicated target vessel revascularization (CI-TVR)  
• Target lesion failure (TLF, composite of cardiac death, TV-MI 
and CI-TLR)  
• Target vessel failure (TVF, composite of cardiac death, TV-MI 
and CI-TVR)  
• Major bleeding defined by the Bleeding Academic Research 
Consortium (BARC) type 3-5  
Point of 
Registration  
Subject registration will occur after the index procedure but prior to 
discharge and up to 3 days post index procedure, upon confirmation 
of the following:  
• Signed informed consent has been obtained;  
• Subject has met all the inclusion and none of the exclusion 
criteria (including both general and angiographic criteria). 
Planned staged procedures are allowed (recommend to be performed 
within 30 days). The site may consent the subject after the initial 
procedure. Subject registration will occur once the last staged 
procedure is performed and the last staged procedure is considered 
as the index procedure.  
Subject Follow-
Up 
Subjects registered in the trial will receive the following clinical 
follow-up: 
• 3 months (90 ± 7 days): office visit (Note: A formal office visit is 
required at 3-month follow-up to ensure a thorough clinical 
evaluation. A telephone contact is an option only for subjects 
who would otherwise be lost to follow-up due to being unable to 
complete an office visit, but a formal follow-up visit is still 
preferred at 3 months.) 
• 6 months (180 ± 14 days): office visit/ telephone contact (office 
visit is strongly recommended whenever possible) 
• 12 months (365 ± 28 days): office visit/ telephone contact (office 
visit is strongly recommended whenever possible)  
Primary Analysis 
Sample Size 
Justification 
To evaluate the safety of the 3-month DAPT, non-inferiority (NI) 
will be tested comparing 3-month DAPT to XIENCE V USA 
historical control for the primary endpoint of all death or all 
myocardial infarction (modified ARC) from 3- to 12-month follow-
up in a “3-month clear” population (defined as subjects who are free 

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
from myocardial infarction [modified ARC], repeat coronary 
revascularization, stroke, or stent thrombosis [ARC 
definite/probable] within 3 months (prior to 3-month visit but at least 
90 days) after stenting AND have been compliant with 3-month 
DAPT without interruption of either aspirin and/or P2Y12 receptor 
inhibitor for > 7 consecutive days).  
This analysis will be stratified by propensity score with the following 
assumptions: 
 
• True event rate for the primary endpoint is assumed to be 
approximately 6.1% for both arms 
• One-sided alpha = 0.025 
• Attrition rate of 15% due to using “3-month clear” population for 
the XIENCE 90 3-month DAPT arm  
• Sample size: ~2,000 for the XIENCE 90 3-month DAPT arm and 
~1,150 for the XIENCE V USA control arm  
• Non-inferiority margin = 2.8% 
• Approximately 87% power  
Major Secondary 
Analysis  
Given the success of the primary analysis for the primary endpoint, 
the following major secondary analyses will be performed:  
• Superiority test for major bleeding rate (BARC type 2-5) from 3- 
to 12-month follow-up will be tested between XIENCE 90 and 
the XIENCE V USA historical control stratified by propensity 
scores. 
 
• Stent thrombosis (ARC definite/probable) from 3- to 12-month 
follow-up of XIENCE 90 will be evaluated against a pre-
specified PG.  
 
Details of the above major secondary analyses could be found in the 
Statistical Analysis Plan (SAP). 
Antiplatelet 
Medication  
Antiplatelet Medication Loading Dose: 
• Subjects must receive a loading dose of aspirin AND a P2Y12 
inhibitor (Clopidogrel, Prasugrel or Ticagrelor). The dosages of 
aspirin and P2Y12 inhibitor shall be determined by physician per 
standard of care and label indication for loading dose usage. The 
choice of P2Y12 inhibitor is per site standard of care, but 
clopidogrel is strongly recommended for HBR subjects.  Per 
physician’s discretion, a loading dose of P2Y12 inhibitor may be 
omitted if the subject was on chronic usage for ≥ 7 days.   

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
 
Antiplatelet Medication Post-Procedure Daily Dose: 
• All subjects must receive ≥75 to ≤100 mg of aspirin daily 
throughout the study. All subjects must maintain a minimum of 
75 mg of clopidogrel daily or 5 or 10 mg of prasugrel daily (10 
mg preferred in most subjects*) or 90 mg twice daily of 
ticagrelor for at least 3 months following the procedure.  
­ The choice of P2Y12 inhibitor is per site standard of care, 
but clopidogrel is strongly recommended for HBR 
subjects. 
­ For subjects taking chronic anticoagulants, dual therapy 
(oral anticoagulant and a P2Y12 inhibitor, clopidogrel 
preferred) may be considered for the first 3 months after 
index procedure per investigator’s discretion.  
• At 3-month follow up, subject will be assessed for their 
eligibility of P2Y12 inhibitor discontinuation. Eligible subjects 
will discontinue P2Y12 inhibitor and receive ≥75 to ≤100 mg of 
aspirin daily through 1-year follow-up during the study if they 
are “3-month clear”, defined as subjects who are free from 
myocardial infarction (modified ARC), repeat coronary 
revascularization, stroke, or stent thrombosis (ARC 
definite/probable) within 3 months (prior to 3-month visit but at 
least 90 days) after stenting AND have been compliant with 3-
month dual antiplatelet therapy (DAPT) without interruption of 
either aspirin and/or P2Y12 receptor inhibitor for > 7 consecutive 
days.  
­ Peri-procedural MI (occurred within 48 hours post index 
procedure) without any clinical symptoms will not be 
considered exclusionary event for the definition of “3-
month clear”.  
­ Dual therapy (oral anticoagulant and a P2Y12 inhibitor, 
clopidogrel is preferred) within the first 3 months post 
index procedure for subjects who are on chronic 
anticoagulants is acceptable for the definition of “3-
month clear”.  
• Subjects who are not “3-month clear” are NOT eligible for 
P2Y12 inhibitor discontinuation at 3-month. These subjects will 
be treated per the investigator's discretion and will continue to be 
followed up through 12 months. 
*For prasugrel subjects < 60 kg in weight or ≥ 75 years of age, a 
maintenance dose of 5 mg per day for 12 months is allowable.

Note: Female patients of childbearing potential should be 
instructed to use safe contraception (e.g., intrauterine devices, 
hormonal contraceptives: contraceptive pills, implants, 
transdermal patches, hormonal vaginal devices, injections with 
prolonged release.) It is accepted, in certain cases, to include

double barrier contraceptive method. However, this should be 
explicitly justified in special circumstances arising from the 
study design, product characteristics and/or study population 
10. Subject is part of a vulnerable population, defined as subject 
whose willingness to volunteer in a clinical investigation could 
be unduly influenced by the expectation, whether justified or 
not, of benefits associated with participation or of retaliatory 
response from senior members of a hierarchy in case of refusal 
to participate.  Examples of populations which may contain 
vulnerable subjects include: individuals with lack of or loss of 
autonomy due to immaturity or through mental disability, 
persons in nursing homes, children, impoverished persons, 
subjects in emergency situations, ethnic minority groups, 
homeless persons, nomads, refugees, and those incapable of 
giving informed consent. Other vulnerable subjects include, for 
example, members of a group with a hierarchical structure such 
as university students, subordinate hospital and laboratory 
personnel, employees of the sponsor, members of the armed 
forces, and persons kept in detention. 
11. Subject is currently participating in another clinical trial that has 
not yet completed its primary endpoint. 
  
Angiographic Exclusion Criteria  
1. Target lesion is in a left main location.  
2. Target lesion is located within an arterial or saphenous vein 
graft. 
3. Target lesion is restenotic from a previous stent implantation. 
4. Target lesion is a total occluded lesion (TIMI flow 0).

5. Target lesion contains thrombus as indicated in the angiographic 
images (per SYNTAX score thrombus definition). 
6. Target lesion is implanted with overlapping stents, whether 
planned or for bailout. 
 
Note: If there is more than one target lesion, all target lesions must 
satisfy the angiographic eligibility criteria. Non-target lesion (i.e., 
lesions that do not meet the angiographic criteria listed above) 
treatments are not allowed during the index procedure. 
Primary Analysis 
Population 
The primary analysis population is “3-month clear” population,

INTRODUCTION 
1.1 
Trial Design 
XIENCE 90 study is a prospective, single arm, multi-center, open label trial to evaluate the 
safety of 3-month dual antiplatelet therapy (DAPT) in subjects at high risk of bleeding (HBR) 
undergoing percutaneous coronary intervention (PCI) with the approved XIENCE family of 
coronary drug-eluting stents. 
The XIENCE family stent systems include commercially approved5 XIENCE Xpedition 
Everolimus Eluting Coronary Stent System (EECSS), XIENCE Alpine EECSS, XIENCE 
PROX EECSS (OUS only)6, XIENCE PROA EECSS (OUS only)7, and XIENCE Sierra 
EECSS, which are all manufactured by Abbott Vascular, Inc., Santa Clara, USA.  The above 
XIENCE family stent systems will hereinafter be called “XIENCE” in this study.  
Approximately 2,000 subjects from approximately 100 sites globally will be registered in this 
study, with at least 50% of subjects in the United States (US). Study population consists of 
non-complex HBR subjects with up to three native coronary artery lesions (a maximum of 
two lesions per epicardial vessel) with reference vessel diameter between 2.25 mm and 4.25 
mm. Eligibility of P2Y12 receptor inhibitor discontinuation will be assessed at 3-month 
follow-up. Subjects who are free from myocardial infarction (modified ARC), repeat 
coronary revascularization, stroke, or stent thrombosis (ARC definite/probable) within 3 
months (prior to 3-month visit but at least 90 days) after stenting AND have been compliant 
with 3-month DAPT without interruption of either aspirin and/or P2Y12 receptor inhibitor for 
> 7 consecutive days are considered as “3-month clear”, and will discontinue P2Y12 receptor 
inhibitor and continued with aspirin monotherapy after 3-month follow-up.   
All registered subjects will be followed at 3, 6 and 12 months post index procedure.  
The data collected from the XIENCE 90 study will be compared with the historical control of 
non-complex HBR subjects treated with standard DAPT duration of up to 12 months from the 
XIENCE V USA study, which is a US post-approval study to evaluate the safety of XIENCE 
V EECSS in “all-comer” population under real-world setting.

BACKGROUND INFORMATION 
2.1 
Background and Rationale 
Although drug-eluting stents (DES) have been shown to effectively reduce restenosis 
compared with bare-metal stents (BMS), there was a concern that DES might lead to an 
increased risk of stent thrombosis based on data from first-generation DES1-4.  This increased 
risk has been attributed, in part, to polymer hypersensitivity reactions, delayed arterial 
healing, endothelial dysfunction, and late acquired stent malapposition.  Stent thrombosis 
generally will manifest in serious clinical outcomes of MI and/or death. As a result of this 
concern, the previous 2011 ACCF/AHA/SCAI guidelines recommend a prolonged duration 
of DAPT, a continuation of at least 1 year of DAPT following DES implantation as compared 
to a minimum of 1 month of DAPT following BMS implantation for patients without acute 
coronary syndrome (ACS)5.  However, these recommendations were based primarily on 
observational data with the first generation DES. Compared with first-generation DES, 
currently used second-generation DES have a lower risk of stent thrombosis. Data from five 
RCTs 6-10of primarily low-risk patients (non-ACS) treated with DES comparing shorter-
duration (3 to 6 months) DAPT with 12 months of DAPT, as well as several meta-analyses 
and data review11-16, did not find an increased risk of stent thrombosis with shorter duration 
of DAPT. Therefore, the most recently published 2016 ACC/AHA guideline updated their 
recommendations to decrease the minimum DAPT duration from 12 months to 6 months after 
DES implantation in patients with stable ischemic heart disease (SIHD)17. 
Long-term DAPT is known to increase the risk of bleeding. Multiple studies have 
demonstrated the relationship between bleeding and an increased risk for short- and long-
term mortality18,19, with major bleeding being identified as an independent predictor of 
mortality with a weight similar to or event greater than MI20. This was confirmed in a recent 
meta-analysis by Palmerini with 12 trials comprising > 34,000 patients randomized to 
different duration strategies of DAPT21. In this meta-analysis (including patient level data of 
11,473 patients from 6 of those 12 RCT trials), bleeding was an independent predictor of 
mortality occurring within 1 year of the bleeding episode (hazard ratio: 6.93; 95% CI: 4.53 to 
10.60; p < 0.0001). More importantly, shorter DAPT was associated with lower rates of all-
cause mortality compared with longer DAPT, which was driven by lower rates of bleeding-
related deaths with shorter DAPT duration. This important finding may underlie the potential 
mortality benefit with shorter DAPT, which is especially relevant for patients who are at high 
risk of bleeding (HBR). 
HBR patients represent approximately 15% or more of patients undergoing PCI22,23.  This 
patient population is of a significant size but is usually excluded from traditional DES 
approval trials.   The traditional standard treatment for HBR patients who undergo 
percutaneous coronary intervention (PCI) is often stenting with BMS followed by 1 month of 
DAPT. While this strategy aims to minimize the risk of bleeding in such patients, the use of 
BMS poses a higher risk of restenosis and re-intervention. Therefore, stenting with DES 
followed by a shortened course of DAPT may represent a more favourable treatment option 
providing that the potential risk of stent thrombosis can be addressed.  With advances in stent 
technology, second-generation DES is equipped with novel stent materials and designs,

polymers, and anti-proliferative agents, which may modify the propensity of DES for 
ischemic events.  It is possible that the same level of safety may be maintained for second-
generation DES even if combined with a significantly shortened course of DAPT. In fact, the 
European ESC/EACTS guidelines have recommended 3 months of DAPT with second-
generation DES for HBR patients undergoing PCI24.  Consistent with the European guideline, 
the updated 2016 ACC/AHA guideline also provided a class IIb recommendation of 3-month 
DAPT in SIHD patients with high risk of bleeding following DES implantation17.  
The second generation everolimus-eluting stent (EES) has been the subject of extensive 
clinical studies across multiple geographies. A consistently low late and very late stent 
thrombosis rate has been demonstrated with EES from randomized controlled studies 25-30 as 
well as real-world registry studies 31,32. The XIENCE family of stents has consistently been 
shown to have the best safety profile among coronary stents, including second-generation 
DES.   
To investigate whether there are any major differences in the risk of stent thrombosis between 
first- and second-generation DES, or between DES and BMS, Palmerini et al. conducted a 
comprehensive network meta-analysis involving 50,844 patients from 49 RCTs implanted 
with DES or BMS33.  This meta-analysis demonstrated that XIENCE V had the lowest rate of 
stent thrombosis within 2 years of implantation compared with other stents.  Not only was 
XIENCE V associated with significantly lower 1-year rate of definite stent thrombosis than 
the other first- and second-generation DES, including Cypher, Taxus, Endeavor, and 
Resolute, XIENCE V was also associated with significantly lower rates of definite stent 
thrombosis than BMS at both 1 year (odds ratio [OR]: 0.23, 95% confidence interval [CI]: 
0.13-0.41) and 2 years (OR: 0.35, 95% CI: 0.17-0 .69), a result not duplicated by other DES.  
The reduction in stent thrombosis with XIENCE V compared with BMS was apparent both 
early (0-30 days) and late (31 days-1 year), suggesting the reduction was not caused by the 
difference in DAPT durations between XIENCE V and BMS as the reduction was already 
evident as early as 30 days when all patients should be treated with DAPT regardless of 
device types.    
Another recent large meta-analysis involving 106,427 patients from 126 RCTs was conducted 
to compare the safety and efficacy of these biodegradable polymer DES (BP-DES) with those 
of durable polymer DES and BMS34.  Among all the stents compared, XIENCE V was the 
safest with a lower risk of clinical events when compared to DES, including BP-DES and 
other first and second generation DES. Even when compared to BMS, XIENCE V was still 
associated with significant reductions in the rates of definite stent thrombosis (rate ratio: 0.35, 
95% CI: 0.21 to 0.53), MI (rate ratio: 0.65, 95% CI: 0.55 to 0.75), and death (rate ratio: 0.72, 
95% CI: 0.58 to 0.90).   
Even in the setting of elevated risk for thrombosis such as acute coronary syndrome, 
XIENCE V still demonstrated a favourable safety outcome as reported in the 
EXAMINATION trial, which was an all-comer trial randomizing 1,504 subjects with ST-
segment elevation myocardial infarction (STEMI) in a 1: 1 ratio to XIENCE V or BMS 
(Vision).  This study demonstrated that XIENCE V was associated with reduced rates of stent 
thrombosis compared with BMS at 1 year and 2 years, with the rates becoming comparable 
between the two groups at 3, 4, and 5 years with similar DAPT usage at 5-year follow-up 
35,36.  It suggests that the risk of stent thrombosis with XIENCE V, if not lower, is at least 
comparable to that of BMS even in this high risk STEMI population. 
The excellent safety profile of XIENCE in terms of stent thrombosis is likely attributed to the 
unique combination of its thin struts (81 µm), the thromboresistant nature of the 
biocompatible fluoropolymer37, and a low loading dose and release kinetics of the anti-

proliferative agent, everolimus. Autopsy studies in humans have suggested that incomplete 
endothelialization of strut surface is a pathologic substrate for late stent thrombosis38,39.  In a 
pre-clinical study conducted in rabbit iliac arteries, areas between struts showed most 
complete coverage (90.4%) for EES compared with other stents at 14 days40.  The rapid strut 
coverage by endothelium with XIENCE V was confirmed in humans in an optical coherence 
tomography (OCT) cohort of the MECHANISM-Elective study41, which showed 93.6% strut 
coverage at 1 month (N=49) and 98% strut coverage at 3 months (N=46) in subjects with 
stable coronary artery disease receiving XIENCE V.   
The XIENCE family of stents is unique from other currently marketed stents in featuring a 
fluorinated co-polymer coating [poly (vinylidene fluoride-co-hexafluoropropylene)] (PVDF-
HFP). This polymer coating not only serves as the vehicle for the controlled elution of 
everolimus, but just as importantly the fluorinated co-polymer offers a non-thrombogenic 
surface through a mechanism known as fluoropassivation42. Pre-clinical models comparing 
inflammation and platelet adhesion among XIENCE V, BMS and Resolute showed that 
XIENCE V had a lower propensity for inflammation and platelet adhesion43,44.  In a series of 
ex vivo studies using porcine arterio-venous shunt model to assess and compare the 
thrombogenicity of XIENCE to different stent platforms, XIENCE showed a significant 
reduction in acute thrombus formation (measured as platelet adhesion) in comparison to BMS 
as well as new generation of bioresorbable polymer-coated stent (Synergy) and polymer-free 
stent (BioFreedom)8. The high degree of stent coverage within 1 and 3 months of implant, 
together with the results of ex vivo studies which consistently showed low thrombogenic 
potential of XIENCE through the unique properties of its fluorinated co-polymer coating, 
provides further evidence to support the safety of shorter DAPT with XIENCE.   
Short-term DAPT has been recently studied in HBR patients. The ZEUS study is a 
randomized, single-blind trial evaluating Endeavor DES vs. BMS combined with a tailored 
course of DAPT for treating subjects who were considered uncertain DES candidates, 
including HBR patients, patients at high risk for thrombosis, and patients at low risk for 
restenosis45.  A total of 1,606 subjects were randomized in a 1:1 ratio to either Endeavor or 
thin-strut BMS (strut thickness < 100 µm).  DAPT duration was prescribed based on patient 
characteristics, rather than stent characteristics, and a personalized regimen of 1-month 
DAPT was allowed.  The primary endpoint of the study was MACE (death, MI, or target 
vessel revascularization [TVR]) at 1 year.  In this study, approximately half of the enrolled 
subjects were HBR patients (51.6%), who were qualified for 1-month DAPT. In the pre-
specified HBR subgroup analysis from ZEUS trial, MACE occurred in 22.6% of the 
Endeavor group and 29% of the BMS group with a hazard ratio 0.75 (p=0.033)46.  The 
definite or probable ST was also significantly reduced in the Endeavor group (2.6% vs. 6.2%, 
p=0.016). 
The LEADERS FREE study is a randomized, double-blind trial evaluating BioFreedom 
combined with 1 month of DAPT for treating HBR patients undergoing PCI as compared to 
BMS47.  A total of 2,466 HBR patients were randomized in a 1:1 ratio to BioFreedom or a 
very similar BMS (Gazelle). All patients received 1 month of DAPT and were to be followed 
at 1, 2, and 4 months, and 1 and 2 years.  The primary safety endpoint, tested for both non-
inferiority and superiority, was a composite of cardiac death, MI, or stent thrombosis

(definite/probable).  The primary efficacy endpoint was clinically driven target lesion 
revascularization (CD-TLR).  At 1 year, the rate of the composite of cardiac death, MI, or 
stent thrombosis was significantly lowered in the BioFreedom group than in the BMS group 
(9.4% (112/1221) vs. 12.9% (154/1211); P < 0.001 for noninferiority and P=0.005 for 
superiority).  The 1-year rate of CD-TLR was also significantly lower in the BioFreedom 
group than in the BMS group (5.1% (59/1221) vs. 9.8% (113/1211), P <0.001).  There was 
also a significant reduction in the 1-year rate of MI with BioFreedom compared with BMS 
(6.1% vs. 8.9%, p = 0.01), whereas no differences in the 1-year rates of stent thrombosis were 
observed between the two groups (2.0% vs. 2.2%, p = 0.75). 
Results from both ZEUS and LEADER FREE suggest that DES can be as safe or even safer 
choice for HBR patients than BMS with short duration of DAPT. The confirmed safety of 
Endeavor and BioFreedom with short-term DAPT for HBR patients in the ZEUS and 
LEADERS FREE studies are of particular relevance to the safety of the proposed study of 
XIENCE.  XIENCE V has consistently been shown to have a better safety profile than 
Endeavor based on results from several meta-analyses33,34.  Pre-clinical studies of 
endothelialization also demonstrate that XIENCE V had a faster rate of strut coverage 
following stent implantation than Endeavor 40, and was equivalent to BioFreedom48.  
Additionally, XIENCE showed a significant reduction in platelet adherence compared to 
BioFreedom stents in ex vivo studies9. Taken together, these clinical data of Endeavor and 
BioFreedom indirectly support the safety to evaluate short-term DAPT with XIENCE.  
There is also clinical data exclusively evaluating short DAPT duration with XIENCE.  
STOPDAPT trial is a prospective multi-center, single-arm study evaluating 3-month DAPT 
duration after XIENCE implantation in 1,525 patients49 . Using the XIENCE group in the 
RESET trial as a historical comparison group, where nearly 90% of patients were on DAPT 
at 1 year, the cumulative incidence of the primary endpoint (a composite of cardiovascular 
death, myocardial infarction, stroke, definite stent thrombosis and TIMI major/minor 
bleeding) at 1 year tended to be lower in the STOPDAPT than in the RESET (2.8% vs. 4.0%, 
p = 0.06). The difference is driven by the significantly lower rate of the composite major 
secondary endpoint of cardiovascular death, myocardial infarction, stroke and definite stent 
thrombosis rate (2.1% vs. 3.2%, p = 0.045) while the TIMI major/minor bleeding rates were 
similar between the two groups (1.0% vs. 1.3%, p = 0.4). The cumulative incidence of 
definite/probable stent thrombosis was also lower in the STOPDAPT (0% vs. 0.3%, p = 
0.03). The STOPDAPT trial data support the safety of short-term DAPT following XIENCE 
V implantation.   
To assess the relationship between stent thrombosis and DAPT usage, a patient-level pooled 
analysis was conducted on a total of 11,219 patients who had complete DAPT usage data 
through the 2-year follow-up period from seven Abbott Vascular-sponsored XIENCE V trials 
(including three pre-approval trials: SPIRIT II, III, IV, and four post-approval single-arm 
registry studies: XIENCE V USA, XIENCE V India, SPIRIT V and SPIRIT Women)50 .  
DAPT requirement varied among these studies.  For the three randomized pre-approval trials, 
at least 6 months of DAPT was required in the protocol.  In the four single-arm registry 
studies, DAPT usage was recommended as per standard of care. The large sample size in this 
pooled analysis allows for a more robust evaluation of stent thrombosis and its association

with DAPT interruption/discontinuation for patients implanted with XIENCE V.  In this 
pooled analysis, the overall rate of definite/probable stent thrombosis at 2 years was 0.75%, 
with 0.36% for early stent thrombosis (within 1 month), 0.29% for late stent thrombosis (1-12 
months) and 0.11% for very late stent thrombosis (after 1 year).  The risk of stent thrombosis 
with permanent DAPT discontinuation after 3 months was low, with similar ST rate through 
2 years compared to those without permanent DAPT discontinuation (0.78% vs. 0.83%, 
respectively).  By propensity and DAPT usage adjusted multivariable analysis, permanent 
DAPT discontinuation in any interval after 90 days was not associated with the occurrence of 
ST.     
The optimal duration of DAPT remains a dilemma for clinicians with the current clinical 
practice. The possible benefits of extended DAPT therapy to prevent late stent thrombosis 
and the progression of atherosclerotic disease need to be weighed against the increased risk of 
bleeding in an individual patient based on stent type. The optimal duration of DAPT is of 
particular interest to HBR patients, in whom it is believed that the benefit of reduced bleeding 
with shorter DAPT outweighs the potential risk of thrombosis and ischemic events. There is 
clearly an unmet medical need to be addressed for this patient population. XIENCE has 
consistently been shown to have the best safety profile among the coronary stents, even when 
compared to BMS and biodegradable polymer DES. The benefit/risk ratio of a shorter 
duration of DAPT following XIENCE implantation in this population has not been 
thoroughly evaluated. Therefore, the XIENCE 90 study is designed to prospectively evaluate 
the safety of XIENCE followed with 3-month DAPT in HBR patients.

Subject Screening and Informed Consent  
5.2.1 Subject Screening 
Subjects admitted for a percutaneous coronary artery revascularization procedure must be 
screened for clinical trial eligibility by a member of the clinical trial team (physician and/or 
research coordinator) previously trained to the clinical trial protocol and if applicable will be 
entered into a site specific screening log.  
Subjects meeting the general inclusion and exclusion criteria will be asked to sign an 
informed consent. Pre-procedure (or baseline) imaging will be used for the final assessment 
of subject eligibility (details are described in Section 5.3). Subjects who do not satisfy the 
angiographic inclusion and exclusion criteria are considered screen failures and will not be 
registered and proceed further in the trial. These subjects will be entered into the screening 
log. Also, the reason for screen failure as well as supporting data will be entered into the log. 
Patient data will be collected following registration into the trial/investigation. 
5.2.2 Informed Consent 
The Investigator or designee, who has been trained on the Protocol, will explain the nature 
and scope of the trial, potential risks and benefits of participation, and answer questions for 
the subjects. All subjects (or legally authorized subjects’ representatives if applicable) must 
sign and date (and time, as per applicable local standards) the Institutional Review Board 
(IRB)/Ethics Committee (EC) approved informed consent (ICF) prior to any clinical 
trial/investigation-specific procedures. All efforts should be made to consent a subject prior 
to index procedure. However, it is acceptable for the subject to provide consent prior to 
hospital discharge and up to 3 days after the index procedure, only if the site confirms that the 
protocol required DAPT regimen is site’s standard of care.  If staged procedures are needed 
for a subject, the site may consent the subject after the initial procedure. 
Obtaining the consent and provisioning of a copy to the subject, along with the date and time 
must be documented in the subject’s medical records. The ICF must be signed by the 
investigator or designate (if allowed per country specific regulations). In addition, the signed 
informed consent must be kept in the subject’s medical records/research chart and a copy 
must be given to the subject or the legally authorized representative. 
In addition, an authorization for use and disclosure of the subject’s protected health 
information, in accordance with the Health Insurance Portability and Accountability Act 
(HIPAA), must be obtained from the subject or their legally authorized representative (US 
only). 
For Live cases at congresses the patients need to sign a specific Live Case ICF, approved by 
the IRB/EC. The investigator must notify Abbott Vascular prior to performing a Live Case.  
FDA approval is also required for a live case conducted in US.

9. Pregnant or nursing subjects and those who plan pregnancy in the period up to 1 year 
following index procedure. Female subjects of child-bearing potential must have a 
negative pregnancy test done within 7 days prior to the index procedure per site standard 
test.  
Note: Female patients of childbearing potential should be instructed to use safe 
contraception (e.g., intrauterine devices, hormonal contraceptives: contraceptive pills, 
implants, transdermal patches, hormonal vaginal devices, injections with prolonged 
release.) It is accepted, in certain cases, to include subjects having a sterilised regular 
partner or subjects using a double barrier contraceptive method. However, this should be 
explicitly justified in special circumstances arising from the study design, product 
characteristics and/or study population. 
10. Subject is part of a vulnerable population, defined as subject whose willingness to 
volunteer in a clinical investigation could be unduly influenced by the expectation, 
whether justified or not, of benefits associated with participation or of retaliatory response 
from senior members of a hierarchy in case of refusal to participate.  Examples of 
populations which may contain vulnerable subjects include: individuals with lack of or 
loss of autonomy due to immaturity or through mental disability, persons in nursing 
homes, children, impoverished persons, subjects in emergency situations, ethnic minority 
groups, homeless persons, nomads, refugees, and those incapable of giving informed 
consent. Other vulnerable subjects include, for example, members of a group with a 
hierarchical structure such as university students, subordinate hospital and laboratory 
personnel, employees of the sponsor, members of the armed forces, and persons kept in 
detention. 
11. Subject is currently participating in another clinical trial that has not yet completed its 
primary endpoint. 
5.3.2 Angiographic Eligibility Criteria 
All angiographic eligibility criteria are based on visual assessment. 
5.3.2.1 
Angiographic Inclusion Criteria 
1. Up to three target lesions with a maximum of two target lesions per epicardial vessel. 
Note: 
• The definition of epicardial vessels means left anterior descending coronary artery 
(LAD), left circumflex coronary artery (LCX) and right coronary artery (RCA) and 
their branches. For example, the patient must not have >2 lesions requiring treatment 
within both the LAD and a diagonal branch in total. 

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
• If there are two target lesions within the same epicardial vessel, the two target lesions 
must be at least 15 mm apart per visual estimation; otherwise this is considered as a 
single target lesion. 
2. Target lesion ≤ 32 mm in length by visual estimation. 
3. Target lesion must be located in a native coronary artery with visually estimated reference 
vessel diameter between 2.25 mm and 4.25 mm.  
4. Exclusive use of XIENCE family of stent systems during the index procedure. 
5. Target lesion has been treated successfully, which is defined as achievement of a final in-
stent residual diameter stenosis of <20% with final TIMI-3 flow assessed by online 
quantitative angiography or visual estimation, with no residual dissection NHLBI grade ≥ 
type B, and no transient or sustained angiographic complications (e.g., distal 
embolization, side branch closure), no chest pain lasting > 5 minutes, and no ST segment 
elevation > 0.5 mm or depression lasting > 5 minutes. 
5.3.2.2 
Angiographic Exclusion Criteria  
1. Target lesion is in a left main location.  
2. Target lesion is located within an arterial or saphenous vein graft. 
3. Target lesion is restenotic from a previous stent implantation.  
4. Target lesion is a total occluded lesion (TIMI flow 0). 
5. Target lesion contains thrombus as indicated in the angiographic images (per SYNTAX 
score thrombus definition).  
6. Target lesion is implanted with overlapping stents, whether planned or for bailout. 
Note: If there is more than one target lesion, all target lesions must satisfy the angiographic 
eligibility criteria. Non-target lesion (i.e., lesions that do not meet the angiographic criteria 
listed above) treatments are not allowed during the index procedure. 
5.4 
Subject Registration  
Subject registration will occur after the index procedure but prior to discharge and up to 3 
days post index procedure, upon confirmation of the following:  
• Signed informed consent has been obtained;  
• Subject has met all the inclusion and none of the exclusion criteria (including both 
general and angiographic criteria). 
Planned staged procedures are allowed (recommend to be performed within 30 days). The 
site may consent the subject after the initial procedure. Subject registration will occur once 
the last staged procedure is performed, and the last staged procedure is considered as the 
index procedure. 
5.5 
Subject Discontinuation 
All registered subjects will be considered to have completed the study upon study completion 
of the 12-month follow-up.  

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
Each registered subject shall remain in the trial until completion of the required follow-up 
period; however, a subject’s participation in any clinical trial is voluntary and the subject has 
the right to withdraw at any time without penalty or loss of benefit. Conceivable reasons for 
discontinuation may include, but not be limited to, the following: 
• Subject death 
• Subject voluntary withdrawal  
• Subject withdrawal by physician as clinically-indicated 
• Subject lost-to follow-up as described below  
• Subject’s follow-up is terminated according to Section 3.4 Early termination of the 
Clinical Trial 
The Sponsor must be notified of the reason(s) for subject discontinuation. The site will record 
this information on the eCRF and source documents and provide this information to the 
Sponsor. Investigators must also report this to their respective IRB/EC as defined by their 
institution’s procedure(s).  
No additional follow–up will be required or data recorded from subjects once withdrawn 
from the trial, except for the status (deceased/alive). 
However, if a subject withdraws from the study due to problems related to the investigational 
device safety or performance, the investigator shall ask for the subject's permission to follow 
his/her status/condition outside of the clinical investigation. 
Lost-to-Follow-up:   
If the subject misses two consecutive scheduled follow up time points and the attempts at 
contacting the subject detailed below are unsuccessful, then the subject is considered lost-to 
follow-up. Site personnel shall make all reasonable efforts to locate and communicate with 
the subject (and document these efforts in the source documents), including the following, at 
each contact time point: 
• A minimum of 2 telephone calls on different days over the specified follow-up windows to 
contact the subject should be recorded in the source documentation, including date, time 
and initials of site personnel trying to make contact. 
• If these attempts are unsuccessful, a letter (certified if applicable) should be sent to the 
subject. 
• If a subject misses one or more non-consecutive follow-up contact time points it will be 
considered a missed visit. The subject may then return for subsequent visits. If the subject 
misses two consecutive time points and the above-mentioned attempts at communicating 
with the subject are unsuccessful, the subject will be considered lost-to-follow-up.  
Note: Telephone contact with General Practitioner, non-study cardiologist or relative without 
presence of subject or indirect documentation obtained via discharge letters will not be 
considered as subject contact. 
Missed Visits: 
• If a subject misses one or more non-consecutive follow-up contact time points, the visit 
will be considered a missed visit and subject is not lost-to-follow-up.   

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
• If subject responds via written communication (including email correspondence), 
providing the protocol required data, these data will be collected in the case report form 
and the visit will not be considered a missed visit.   
5.6 
Total Expected Duration of the Clinical Investigation 
The total expected duration of the clinical investigation is approximately 30 months. 
5.7 
Expected Duration of Each Subject’s Participation 
The expected duration of each subject’s participation in this clinical investigation is 
approximately 12 months. 
5.8 
Number of Subjects Required to be Included in the Clinical Investigation 
Approximately 2,000 subjects are required to be included in the clinical investigation. 
5.9 
Estimated Time Needed to Register this Number  
The estimated time needed to register 2,000 subjects is approximately 18 months. 
5.10 
Trial Completion 
A Trial Completion eCRF must be completed when: 
• the subject is considered lost to follow-up per the above definition or  
• the subject withdraws from the Clinical Trial or 
• the investigator withdraws the subject from the Clinical Trial or 
• the subject has died or 
• upon Clinical Trial completion or 
• sponsor termination of trial. 
Sponsor must be notified of the reason for subject discontinuation. The site will provide this 
information on the eCRF. Investigators must also report this to their EC/IRB as defined by 
their institution’s procedure. Subjects will not be replaced. 
6.0 
TREATMENT AND EVALUATION  
6.1 
Baseline and Pre-procedure 
6.1.1 Laboratory Assessments  
Baseline 12-lead electrocardiogram (ECG) and laboratory assessments (such as blood counts, 
chemistry panel and lipid panel, cardiac enzymes, etc.) should be obtained per site’s standard 
of care. Baseline laboratory results related to inclusion/exclusion criteria should be available 
and reviewed prior to the index procedure for screening. 
6.1.2 Clinical Assessments 
Subject demographics (age, gender, race), height, weight, family history of coronary artery 
disease (CAD), smoking status, cardiac history (myocardial infarction, diabetes mellitus, 
hypertension, hypercholesterolemia, and previous PCI/CABG information), subject’s current 
cardiac status (presentation of CAD and multivessel disease) and indication of high bleeding 
risk (per criteria specified in Section 5.3.1.1) will be obtained and recorded in electronic case 
report form (eCRF).   
6.1.3 Pre-procedure Antiplatelet Medication 
Antiplatelet loading dose is required in this trial: 

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
• Subjects must receive a loading dose of aspirin AND a P2Y12 inhibitor (Clopidogrel, 
Prasugrel or Ticagrelor). The dosages of aspirin and P2Y12 inhibitor shall be 
determined by physician per standard of care and label indication for loading dose 
usage. The choice of P2Y12 inhibitor is per site standard of care, but clopidogrel is 
strongly recommended for HBR subjects.  Per physician’s discretion, a loading dose 
of P2Y12 inhibitor may be omitted if the subject was on chronic usage for ≥ 7 days.  
The details of the antiplatelet loading dose, including type of drug, dosage, date and time, 
will be recorded in eCRF.  
6.2 
Index Procedure 
Only XIENCE stent can be used for target lesion(s). Stent implantation procedure should be 
performed according to the instruction for use (IFU) of the XIENCE family stent used. If 
XIENCE stent is delivered beyond the guide catheter but not implanted, the subject should 
not be registered in the study. If other DES was implanted, the subject should not be 
registered in the study.  
In this study, a maximum of three target lesions may be treated with a maximum of two target 
lesions per epicardial vessel. Non-target lesion (i.e., lesions that do not meet the angiographic 
eligibility criteria) treatments are not allowed during the index procedure.  
Planned staged procedures are allowed (recommend to be performed within 30 days). The 
site may consent the subject after the initial procedure. Subject registration will occur once 
the last staged procedure is performed and the last staged procedure is considered as the 
index procedure. Post-procedure DAPT duration will be measured from the last staged 
procedure.  Any planned stenting procedure must be done prior to subject registration. The 
subject must not have any additional stenting procedure planned after the index procedure.    
Subjects may receive appropriate anticoagulation and other therapy according to standard 
hospital practice.  
Overlapping stents are not allowed in the study, whether planned or for bailout. Subjects who 
received overlapping stents should not be registered in this study.  
Lesion characteristics (lesion location, % diameter stenosis, TIMI flow, RVD, lesion length, 
thrombus presence, bifurcation or not, lesion complexity), device (device name, size, number 
of device implanted, bailout usage, overlapping stent) and procedural information (procedure 
time, access site, procedural anticoagulant and anti-thrombotic medications, any procedure 
complications) will be collected and recorded in eCRF.  
6.3 
Post–procedure  
6.3.1 Post-procedure Laboratory and Clinical Tests 
Post-procedure ECG and cardiac enzymes are not mandatory in the study, and shall be 
performed per site’s standard care. CK and CK-MB are preferred. If CK and CK-MB are not 
available, troponin should be collected. 
6.3.2 Antiplatelet Medications during Follow-up  
• All subjects must receive ≥75 to ≤100 mg of aspirin daily throughout the study. All 
subjects must maintain a minimum of 75 mg of clopidogrel daily or 5 or 10 mg of 
prasugrel daily (10 mg preferred in most subjects*) or 90 mg twice daily of ticagrelor for 
at least 3 months following the procedure.  
­ The choice of P2Y12 inhibitor is per site standard of care, but clopidogrel is 
strongly recommended for HBR subjects. 

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
­ For subjects taking chronic anticoagulants, dual therapy (oral anticoagulant and a 
P2Y12 inhibitor, clopidogrel preferred) may be considered for the first 3 months 
after index procedure per investigator’s discretion. 
• At 3-month follow up, subject will be assessed for their eligibility of P2Y12 inhibitor 
discontinuation. Eligible subjects will discontinue P2Y12 inhibitor and receive ≥75 to 
≤100 mg of aspirin daily through 1-year follow-up during the study if they are “3-month 
clear”, defined as subjects who are free from myocardial infarction (modified ARC), 
repeat coronary revascularization, stroke, or stent thrombosis (ARC definite/probable) 
within 3 months (prior to 3-month visit but at least 90 days) after stenting AND have been 
compliant with 3-month dual antiplatelet therapy (DAPT) without interruption of either 
aspirin and/or P2Y12 receptor inhibitor for > 7 consecutive days.  
­ Peri-procedural MI (occurred within 48 hours post index procedure) without any 
clinical symptoms will not be considered exclusionary event for the definition of 
“3-month clear”. 
­ Dual therapy (oral anticoagulant and a P2Y12 inhibitor, clopidogrel preferred) 
within the first 3 months post index procedure for subjects who are on chronic 
anticoagulants is acceptable for the definition of “3-month clear”. 
• Subjects who are not “3-month clear” are NOT eligible for P2Y12 inhibitor 
discontinuation at 3-month. These subjects will be treated per the investigator's discretion 
and will continue to be followed up through 12 months. 
*For prasugrel subjects < 60 kg in weight or ≥ 75 years of age, a maintenance dose of 5 mg 
per day for 12 months is allowable.   
The use of the above antiplatelet medications, including the start and stop date, any changes, 
as well as the reason to stop, will be documented in the eCRF. 
6.3.3 Other Chronic Concomitant Medications 
Administration of concomitant medications other than any approved P2Y12 inhibitors and 
aspirin are not required in this protocol. Subjects may receive other medications as needed 
per physician’s discretion.  
6.4 
Clinical Follow-up for All Subjects 
Subjects registered in the trial will receive the following clinical follow-up: 
• 3 months (90 ± 7 days): office visit (Note: A formal office visit is required at 3-month 
follow-up to ensure a thorough clinical evaluation. A telephone contact is an option 
only for subjects who would otherwise be lost to follow-up due to being unable to 
complete an office visit, but a formal follow-up visit is still preferred at 3 months.) 
• 6 months (180 ± 14 days): office visit/ telephone contact (office visit is strongly 
recommended whenever possible) 
• 12 months (365 ± 28 days): office visit/ telephone contact (office visit is strongly 
recommended whenever possible) 
 
Clinical follow-up visits should be conducted by the investigator or study personnel who 
have been trained to the protocol. At 3-month follow-up visit, the investigator or designee 

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
will assess whether the subject is “3-month clear” and eligible for P2Y12 inhibitor 
discontinuation per criteria defined in Section 6.3.2.  
All registered subjects will be followed up through 12 months, regardless of eligibility to 
discontinue P2Y12 inhibitor. 
The following information will be collected at each of the time points: 
• Any adverse events  
• Use and compliance of protocol required antiplatelet medication 
• Details of any subsequent coronary interventions (e.g., repeat PCI or CABG) 
Note that information obtained through indirect contacts with a subject’s healthcare provider 
or immediate family member will NOT be considered as a study visit. 
6.5 
Additional Follow-up Visits for All Subjects  
Additional subject visits, such as unscheduled visits, may occur as clinically warranted. The 
following information will be collected and recorded in eCRF:  
• Any adverse events  
• Use and compliance of protocol required antiplatelet medication 
• Details of any subsequent coronary interventions (e.g., repeat PCI or CABG) 
If an unscheduled visit is conducted due to a suspected ischemic cardiac event, cardiac 
enzymes and ECG may be performed per site’s standard care. CK and CK-MB are preferred. 
If CK and CK-MB are not available, troponin should be collected. 
All efforts must be made to obtain follow-up information on subjects who have undergone 
procedures or have been treated for adverse events in a non-trial-related hospital(s). 
7.0 
ADVERSE EVENTS 
To comply with worldwide standards and guidelines on clinical trial adverse event reporting, 
AV has developed uniform and worldwide applicable standard definitions and reporting 
timelines to be used and adhered to by the investigators. 
7.1 
Definition  
7.1.1 Adverse Event 
An adverse event (AE) is any untoward medical occurrence, unintended disease or injury, or 
untoward clinical signs (including abnormal laboratory findings) in subjects, users or other 
persons, whether or not related to the investigational medical device. 
Note 1: This definition includes events related to the investigational medical device or the 
comparator. 
Note 2: This definition includes events related to the procedures involved. 
Note 3: For users or other persons, this definition is restricted to events related to 
investigational medical devices. 
An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
(investigational) product, whether or not related to the medicinal (investigational) product.  

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
7.1.2 Serious Adverse Event 
If the AE meets any of the criteria below, it is regarded as a serious adverse event (SAE).  
a) Led to a death, 
b) Led to a serious deterioration in health that either: 
1) Resulted in a life-threatening illness or injury, or 
2) Resulted in a permanent impairment of a body structure or a body function, or 
3) Required in-patient hospitalization or prolongation of existing hospitalization, or 
4) Resulted in medical or surgical intervention to prevent life threatening illness or 
injury or permanent impairment to a body structure or a body function. 
c) Led to fetal distress, fetal death or a congenital abnormality or birth defect. 
d) An important medical event that may not result in death, be life-threatening, or require 
hospitalization but may be considered serious when, based upon appropriate medical 
judgment, may jeopardize the subject and/or may require intervention to prevent one of the 
outcomes listed in this definition. 
Note 1: This includes device deficiencies that might have led to a serious adverse event if a) 
suitable action had not been taken or b) intervention had not been made or c) if circumstances 
had been less fortunate. These are handled under the SAE reporting system. 
Note 2: A planned hospitalization for pre-existing condition, or a procedure required by the 
Clinical Investigation Plan, without a serious deterioration in health, is not considered to be a 
serious adverse event. 
7.1.3 Device Deficiency/Device Malfunction 
Device deficiency (DD) is defined as an inadequacy of a medical device related to its 
identity, quality, durability, reliability, safety or performance, such as malfunction, misuse or 
use error and inadequate labeling. This includes the failure of the device to meet its 
performance specifications or otherwise perform as intended. Note: Performance 
specifications include all claims made in the labeling of the device. 
A device malfunction (DM) is the failure of a device to meet its performance specifications 
or otherwise perform as intended, when used in accordance with the instructions for use or 
the study protocol. 
7.2 
Device Relationship 
Determination of whether there is a reasonable possibility that an investigational product or 
device caused or contributed to an AE is to be determined by the Investigator and recorded 
on the appropriate eCRF form. Determination should be based on assessment of temporal 
relationships, evidence of alternative etiology, medical/biologic plausibility, and patient 
condition (pre-existing condition). 
7.2.1 Unanticipated (Serious) Adverse Device Effect  
Unanticipated (serious) adverse device effect [U(S)ADE] refers to any serious adverse effect 
on health or safety or any life-threatening problem or death caused by, or associated with, a 
device, if that effect, problem, or death was not previously identified in nature, severity, or 
degree of incidence in the investigational plan or application (including a supplementary plan 
or application), or any other unanticipated serious problem associated with a device that 
relates to the rights, safety, or welfare of subjects.

7.3 
Adverse Event Reporting 
7.3.1 Adverse Event Reporting 
For all registered subjects, AE reporting starts when the guiding catheter enters the subject’s 
vasculature. All AEs will be collected through 12-month follow-up visit.   
Unchanged, chronic, non-worsening or pre-existing conditions are not AEs and should not be 
recorded on the AE eCRF page.  
Non-cardiac related abnormal laboratory values will not be considered AEs unless:  
1) the investigator determined that the value is clinically significant,  
2) the abnormal lab value required intervention, or  
3) the abnormal lab value required subject termination from the study. 
The Investigator will monitor the occurrence of AEs for each subject during the course of the 
clinical trial and report as required by this protocol in Section 7 per AE and SAE definitions. 
AEs need to be collected as of the time point of guiding catheter enters the subject’s 
vasculature on the appropriate AE eCRF form. Additional information with regards to an 
adverse event should be updated within the appropriate case report form.  
A fax form will be made available to allow the investigator to report SAEs in the event the 
entry cannot be made in the EDC. This does not replace the EDC reporting system. All 
information must still be entered in the EDC system as soon as feasible.  
The investigator should report all SAEs to the Sponsor as soon as possible but no later than 
outlined below.  
Study site 
Reporting timelines 
All Study Sites 
SAEs must be reported no later than 3 calendar days from the day the 
study personnel became aware of the event or as per the investigative 
site’s local requirements, if the requirement is more stringent than 
those outlined. 
The date the site staff became aware that the event met the criteria of a serious adverse event 
must be recorded in the source document.  
Serious adverse events that occurred in the user or persons other than the study subject should 
not be entered in the EDC system, however need to be reported via the SAE Notification 
Form.   
The Investigator will further report the SAE to the local IRB/EC according to the institution’s 
IRB/EC reporting requirements.    
7.3.2 Unanticipated Serious Adverse Device Effect Reporting to Sponsor and IRB 
Abbott Vascular requires the Investigator to report any USADE to the sponsor within 3 
calendar days of the investigator’s knowledge of the event, unless local requirements are 
more stringent, and to the IRB/EC per IRB/EC requirements.  
7.3.3 Device Deficiency/Device Malfunction Reporting  
 
All device deficiencies/malfunctions should be reported within the EDC System on the 
appropriate eCRF form. A fax form will be made available to allow the investigator to report 
device deficiencies/malfunctions in the event that the entry cannot be made in the EDC. This 

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
does not replace the EDC reporting system. All information must still be entered in the EDC 
system as soon as feasible.  
In case a device deficiency/malfunction occurred before the patient ID has been assigned, the 
device deficiency should be reported to the Sponsor via the fax form. 
The investigator should report all DDs/DMs to the Sponsor as soon as possible but no later 
than outlined below:  
Study sites 
Reporting timelines 
All Study Sites 
DDs/DMs must be reported no later than 3 calendar days from the 
day the study personnel became aware of the event or as per the 
investigative site’s local requirements, if the requirement is more 
stringent than those outlined. 
The device, if not implanted or not remaining in the subject, should be returned to Abbott 
Vascular.   
Device deficiencies/malfunctions should be reported to the IRB/EC per the investigative 
site’s local requirements.  
 
If there is a device deficiency/malfunction related to other AV products, please contact the 
Product Performance Group (PPG) by e-mail: qahotline@av.abbott.com or contact AV Sales 
person to complete a Product Experience Form (PER Form). 
7.3.4 Adverse Event Reporting to Country Regulatory Authorities by the Sponsor  
The Sponsor or designee will report the SAEs and DDs/product experiences (PEs) to the 
country regulatory authority, per local requirements.  
7.4 
Safety Monitoring by Data Safety Monitoring Board (DSMB) 
The DSMB will serve in an advisory role to Abbott Vascular to ensure safety by reviewing 
cumulative data from the clinical trial at prescribed intervals for the purpose of safeguarding 
the interests of trial participants.  
The DSMB may consider a recommendation for modifications or termination of the trial 
based on any perceived safety concerns regardless of statistical significance. The 
recommendations of the DSMB are not binding, and all final decisions related to trial 
modifications rest with Abbott Vascular. 
8.0 
ADJUDICATION OF EVENTS 
The Clinical Events Committee (CEC) is comprised of qualified physicians who are not 
investigators in the trial. The CEC will review and adjudicate pre-specified events reported 
by trial investigators or identified by the Clinical Safety personnel/designate for the trial as 
documented in CEC Manual of Operations (MOPs).  
9.0 
STATISTICAL ANALYSIS  
9.1 
Statistical Overview  
The XIENCE 90 trial is powered based on primary endpoint of all death or all myocardial 
infarction [modified ARC] (Death/MI) from 3- to 12-month follow-up.  
Primary endpoint analysis for 3-month DAPT 

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
The primary endpoint of Death/MI between 3-month and 12-month follow-up will be 
evaluated based on the “3-month clear” population (as defined in section 9.2). The hypothesis 
test is designed for non-inferiority of 3-month DAPT from XIENCE 90 compared to standard 
DAPT duration up to 12 months from XIENCE V USA historical control for the primary 
endpoint with one-sided alpha of 0.025 after propensity score stratification. The null (H0) and 
alternative (HA) hypothesis are of the following form: 
                        H0: Death/MI3m-DAPT  -  Death/MIXience V USA   ≥ δ 
HA: Death/MI3m-DAPT  -  Death/MIXience V USA  < δ 
A stratified statistical method through propensity score will be performed to test non-
inferiority (NI) of 3-month DAPT to XIENCE V USA historical control. 
The trial success is defined as passing the non-inferiority test on the primary endpoint 
Death/MI for the “3-month clear” population.  
Major secondary endpoint analyses for 3-month DAPT  
If the hypothesis testing for the primary endpoint is successful, the following major 
secondary analyses will be performed. 
A superiority test for the major secondary endpoint of BARC type 2-5 bleeding. Stratified 
propensity score method will be applied for the analysis of the major secondary endpoint as 
well. This test will be based on one-sided alpha of 0.025. The null (H0) and alternative (HA) 
hypotheses are of the following form: 
                  H0: B3m-DAPT –BXience V USA  ≥ 0 
HA: B3m-DAPT –BXience V USA  < 0 
B3m-DAPT and BXience V USA are major bleeding rates (BARC type 2-5) between 3-month and 12-
month follow-up for XIENCE 90 and XIENCE V USA historical control, respectively.  
Major secondary endpoint of stent thrombosis (ARC definite/probable) from 3 to 12 months 
of XIENCE 90 will be evaluated against a pre-specified performance goal (PG). 
Other secondary clinical endpoints will be descriptively analyzed.   
9.2 
Analysis Populations  
The primary analysis population is “3-month clear” population, defined as subjects who are 
free from myocardial infarction (modified ARC), repeat coronary revascularization, stroke, or 
stent thrombosis (ARC definite/probable) within 3 months (prior to 3-month visit but at least 
90 days) after stenting AND have been compliant with 3-month dual antiplatelet therapy 
(DAPT) without interruption of either aspirin and/or P2Y12 receptor inhibitor for > 7 
consecutive days. 
9.3 
Sample Size Calculations and Assumptions  
9.3.1 Primary Endpoint  
To evaluate the safety of the 3-month DAPT, the non-inferiority test will be performed on the 
primary endpoint of Death/MI between 3-month and 12-month follow-up for XIENCE 90 
against XIENCE V USA historical control after propensity score stratification with the 
following assumptions: 
True event rate for the primary endpoint is assumed to be 6.1% for both arms    
Non-inferiority margin: 2.8%  
Attrition rate of 15% due to using “3-month clear” population for the XIENCE 90 3-month 
DAPT arm  
One-sided alpha = 0.025 
Sample size in the control arm: ~1,150 
Approximately 87% power 
Sample size of 2,000 subjects in XIENCE 90 will be required for this test.  
The sample size calculations were performed using NCSS PASS 11 (Hintze, J., 2011, NCSS, 
LLC. Kaysville, Utah).

9.3.2 Major Secondary Endpoint  
Given the success of the primary analysis for the primary endpoint, the following major 
secondary analyses will be performed: 
Superiority test for the major bleeding rate (BARC type 2-5) from 3- to 12-month follow-up 
will be tested between XIENCE 90 and the XIENCE V USA historical control stratified by 
propensity scores. 
Stent thrombosis (ARC definite/probable) from 3- to 12-month follow-up of XIENCE 90 will 
be evaluated against a pre-specified performance goal (PG).  
Details of the above major secondary analyses could be found in the Statistical Analysis Plan 
(SAP). 
 
9.4 
Statistical Analyses  
A stratified statistical method through propensity score will be used to test non-inferiority of 
3-month DAPT in XIENCE 90 to XIENCE V USA historical control for the primary 
endpoint of death/MI at a 0.025 significant level.  
Major secondary analyses will be performed only if the primary hypothesis testing is 
successful. 
Analyses of other secondary endpoints and additional endpoints will be descriptive in nature. 
For binary variables such as TLR, TVR, counts, percentages and 95% confidence intervals 
will be calculated, and p-values may be presented for hypothesis generating purposes. 
Pearson’s Chi-squared test of Fisher’s exact test will be performed when appropriate. 
For continuous variables such as age, means, standard deviation, and 95% confidence 
intervals for the mean will be calculated and p-values may be presented for hypothesis 
generating purposes. For time-to-event variables, such as time to Death/MI, survival curves 
will be constructed using Kaplan-Meier estimates, and log rank test results will be displayed. 
Unless specified, analyses will be performed with pooled data across all study sites. 
For further details, refer to the Statistical Analysis Plan (SAP). 
9.4.1 Primary Endpoint Analysis  
A non-inferiority test will be performed on the primary endpoint of Death/MI between 3-
month and 12-month follow up for the “3-month clear” population of XIENCE 90 3-month 
DAPT arm and the XIENCE V USA historical control stratified by propensity scores. 
Details of the analyses for the powered primary endpoint can be found in the Statistical 
Analysis Plan (SAP). 
9.4.2 Major Secondary Endpoint Analysis 
• Superiority will be tested for the major secondary endpoint of major bleeding (BARC 
type 2-5) between 3-month and 12-month follow up for the “3-month clear” 
population of XIENCE 90 3-month DAPT arm and the XIENCE V USA historical 
control stratified by propensity scores.   
• Stent thrombosis (ARC definite/probable) from 3 to 12 months for the “3-month 
clear” population of XIENCE 90 will be evaluated against a pre-specified 
performance goal (PG).  
9.4.3 Secondary Endpoint Analyses  
Other secondary and additional clinical endpoints will be descriptively analyzed.

9.4.4 Subgroup Analysis 
Analyses will be performed for subgroups such as gender (male versus female), diabetes 
(diabetes versus non-diabetes), ethnicity (white versus non-white), age (age ≥ median versus 
< median), clinical presentation (ACS NSTEMI, ACS unstable angina, non-ACS), and the 
subgroup of US elderly patient with age ≥ 65 years old.  
9.4.5 Procedures for Accounting for Missing, Unused or Spurious Data 
The primary and secondary endpoint analyses will be evaluated after propensity score 
stratification. To handle missing data, multiple imputation method will be performed to 
compute propensity scores from these datasets. For further details, refer to the SAP. 
All other analyses will be based on available data with missing data excluded. Any unused or 
spurious data will be noted as appropriate in the final report.

and to determine policy regarding any publications arising from data generated from the 
performance of the trial. 
11.7.2  Data Safety Monitoring Board (DSMB) 
 
The Data Safety Monitoring Board (DSMB) is an independent multidisciplinary group that is 
restricted to individuals free of apparent significant conflicts of interest. The source of these 
conflicts may be financial, scientific, or regulatory in nature. The DSMB is typically 
composed of at least two physicians with relevant interventional experience (e.g., vascular 
surgeon, interventional radiologist, interventional cardiologist) and a biostatistician and is 
responsible for making recommendations regarding endpoint analyses and any potentially 
significant patient safety-related observations. The composition of the DSMB, frequency of 
the DSMB sessions and the statistical monitoring guidelines are described in detail in the 
DSMB charter. DSMB meeting minutes and recommendations are forwarded to Abbott 
Vascular.    
In addition to an Abbott Vascular/designee safety monitor reviewing adverse events at 
regular intervals, a monthly listing of Adverse Events will be sent to the DSMB Chair or 
designee for review. If a safety signal is identified during this review, then the DSMB chair 
will call for an ad hoc full DSMB meeting. 
11.7.3 Clinical Events Committee (CEC)

15.0 
RISK ANALYSIS 
 
The optimal duration of DAPT remains a dilemma for clinicians with the current clinical 
practice, and is of particular interest to HBR patients which represent approximately 15% or 
more of patients undergoing PCI22,23. The default management of care for HBR patients who 
undergo PCI is often stenting with BMS followed by 1 month of DAPT. The European 
ESC/EACTS guidelines have recommended 3 months of DAPT with second-generation DES 
for HBR patients undergoing PCI24.  Consistent with the European guideline, the updated 
2016 ACC/AHA guideline also provided a class IIb recommendation of 3-month DAPT in 
SIHD patients with high risk of bleeding following DES implantation17. Studies with some 
DES (Endeavor, BioFreedom) have demonstrated safety of short-term DAPT for HBR 
patients45,47. 
 
XIENCE has consistently been shown to have the best safety profile among the coronary 
stents, even when compared to BMS, in both clinical trials and commercial data analysis. 
However, the benefit/risk ratio of a shorter duration of DAPT following XIENCE 
implantation in the HBR population has not been thoroughly evaluated. There is clearly an 
unmet medical need to be addressed for the HBR patient population as the possible benefits 
of extended DAPT therapy to prevent late stent thrombosis and the progression of 

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
atherosclerotic disease need to be weighed against the increased risk of bleeding in an 
individual patient. Therefore, the XIENCE 90 study is designed to prospectively evaluate the 
safety of XIENCE followed with 3-month DAPT in HBR patients. 
15.1 
Anticipated Clinical Benefits 
The excellent safety profile of XIENCE family of stents has been well demonstrated. Stent 
implantation and the following medical treatment are the same for subjects registered in this 
study as if they are not participating in this clinical study, except for DAPT duration. Short-
term DAPT may decrease the risk of bleeding in HBR subjects. Participation of this study 
contributes to defining the optimum duration of DAPT in HBR subjects treated with 
XIENCE. 
15.2 
Foreseeable Adverse Events and Anticipated Adverse Device Effects  
Observed and potential adverse events occurring with the XIENCE family of stents are listed 
in the IFUs. The incidence of these adverse events is comparable to other PCI devices. There 
may be risks related to the device that are unknown at present. 
Please refer to the drug labelling (most recent versions available at www.fda.gov – drugs - 
drugs@fda and www.ema.europa.eu – find medicine – human medicines), and published 
guidelines on PCI and DAPT use17,24 for information on bleeding and other risks associated 
with DAPT use. 
Short-term DAPT use may decrease the risk of bleeding in HBR subjects, but may increase 
the risk of late stent thrombosis and progression of atherosclerotic disease.  
15.3 
Residual Risks Associated with the Investigational Device, as Identified in the 
Risk Analysis Report 
The XIENCE Risk Assessment Report12 utilizes the Failure Modes and Effects Analysis 
(FMEA) tool to systematically identify potential hazards associated with the process, design, 
components, and use of the XIENCE product family. Based upon preclinical, clinical, bench 
data, and commercial post-production data, all residual risks are appropriate and acceptable. 
The benefit of treatment from the XIENCE outweighs the potential risks to the patient. 
Comprehensive analysis of product level clinical data, including clinical trial, post-marketing, 
and literature data, confirms that any undesirable risks identified are outweighed by the 
clinical benefits of the device13 . 
15.4 
Risks Associated with Participation in Clinical Investigation 
All procedures required by the protocol are routine standard of care. There are no additional 
risks to the subjects, except that short-term DAPT may increase the risk of stent thrombosis 
and ischemic events. 
15.5 
Possible Interactions with Protocol Required Concomitant Medications 
Other than DAPT, the study protocol does not require concomitant medications.

Steps that will be Taken to Control or Mitigate the Risks 
In-depth recommendations, special precautions and instructions regarding patient selection, 
vessel sizing, device handling, device placement and system removal are included in the IFU. 
It is also stated in the IFU that the devices can only be used by physicians who have received 
appropriate training on how to use the device. This statement is interpreted to mean that the 
physician users are expected to be aware of the known and foreseeable safety risks associated 
with the use of the devices including the surgical and/or non-surgical treatment of these 
conditions. 
Risks associated with the use of the device during this clinical study are minimized through 
device design, investigator selection and training, pre-specified patient eligibility 
requirements, study monitoring to ensure adherence to the protocol, clinical follow-up by 
investigator or designee at pre-specified time points and the use of a DSMB.  
All adverse events and device deficiencies observed in this study will be reported to Abbott 
Vascular, will be monitored internally for safety surveillance purposes, and will be reported 
to the regulatory authorities, as applicable (Refer to section 7.3 of this protocol ). 
Abbott Vascular updates the risk assessment reports and conducts comprehensive analysis of 
product level clinical data on a regular basis. 
The XIENCE family of stents has not been tested in pregnant women. Effects on the 
developing fetus and excretion of everolimus in breast milk have not been studied. Pregnant 
or nursing subjects and those who plan pregnancy in the period up to 1 year following index 
procedure are excluded from participation in the clinical study. Female subjects of child-
bearing potential must have a pregnancy test done within 7 days prior to the index procedure 
with negative results known to confirm eligibility prior to registration.  
15.7 
Risk to Benefit Rationale  
The XIENCE family of stent has consistently been shown to have the best safety profile 
among the coronary stents, in both clinical trials and commercial data analysis. The optimal 
duration of DAPT remains a dilemma for clinicians with the current clinical practice, and is 
of particular interest to HBR patients which represent approximately 15% or more of patients 
undergoing PCI. The XIENCE 90 study is designed to prospectively evaluate the safety of 
XIENCE followed with 3-month DAPT in HBR patients. Reduced DAPT treatment duration 
may decrease the risk of bleeding, but may increase the risk of late stent thrombosis and 
progression of atherosclerotic disease, although studies with other DES have demonstrated 
safety of short-term DAPT for HBR patients. Other than a reduction in the duration of DAPT, 
all procedures required by the protocol are routine standard of care and conducted according 
to the current IFU.

APPENDIX II: 
DEFINITIONS 
 
CLINICAL ENDPOINT DEFINITIONS 
 
DEATH (Per ARC Circulation 2007; 115: 2344-2351) 
All deaths are considered cardiac unless an unequivocal non-cardiac cause can be established. 
Specifically, any unexpected death even in patients with coexisting potentially fatal non-
cardiac disease (e.g. cancer, infection) should be classified as cardiac.  
 
Cardiac death:  
Any death due to proximate cardiac cause (e.g. MI, low-output failure, fatal arrhythmia), 
unwitnessed death and death of unknown cause, all procedure related deaths including those 
related to concomitant treatment. 
 
Vascular death: 
Death due to non-coronary vascular causes such as cerebrovascular disease, pulmonary 
embolism, ruptured aortic aneurysm, dissecting aneurysm, or other vascular cause. 
   
Non-cardiovascular death: 
Any death not covered by the above definitions such as death caused by infection, malignancy, 
sepsis, pulmonary causes, accident, suicide or trauma. 
 
MYOCARDIAL INFARCTION (MI) 
 
MI Definition (Modified ARC) 
 
Patients present any of the following clinical or imaging evidence of ischemia: 
• Clinical symptoms of ischemia;  
• ECG changes indicative of new ischemia - new ST-T changes or new left bundle branch 
block (LBBB), development of pathological Q waves*;  
• Imaging evidence of a new loss of viable myocardium or a new regional wall motion 
abnormality)  
 
AND confirmed with elevated cardiac biomarkers** per ARC criteria (Circulation 2007; 115: 
2344-2351): 
• Periprocedural MI: 
• Within 48h after PCI: CK-MB >3 x URL or Troponin > 3 x URL with baseline value 
< URL 
• Within 72h after CABG: CK-MB >5 x URL or Troponin > 5 x URL with baseline 
value < URL 
• Spontaneous MI (> 48h following PCI, > 72h following CABG): CK-MB > URL or 
Troponin > URL with baseline value < URL 
 
* Pathologic Q waves may be defined according to the Global Task Force, Minnesota code, or Novacode  
**The assessment of CK-MB is preferred over the assessment of troponin for the diagnosis of peri-procedural MI, if possible. 
Baseline biomarker value requiring before study procedure and presumes a typical rise and fall.  
 
Electrocardiographic Classification 
 
• Based on Q-Wave 
o Q-wave MI [QMI] 

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
 Development of new pathological Q waves in 2 or more contiguous 
leads with or without post- procedure CK or CK-MB levels elevated 
above normal. 
 
o Non Q-wave MI [NQMI] 
 All MIs not classified as Q waves. 
 
• Relation to the Target Vessel 
All infarcts that cannot be clearly attributed to a vessel other than the target vessel 
will be considered related to the target vessel. 
 
WHO MI Definition 
 Myocardial infarctions will also be adjudicated based on the following definition:  
 Q wave MI: Development of new, pathological Q wave on the ECG  
 
 Non-Q wave MI: Elevation of CK levels to ≥ two times the upper limit of normal (ULN) 
with elevated CK-MB in the absence of new pathological Q waves 
  
 
STENT THROMBOSIS (Per ARC Circulation 2007; 115: 2344-2351) 
 
Timing:  
Acute stent thrombosis*:  
 
0 - 24 hours post stent implantation  
Subacute stent thrombosis*:   
>24 hours . 30 days post stent implantation  
Late stent thrombosis†:  
 
30 days - 1 year post stent implantation  
Very late stent thrombosis†:   
>1 year post stent implantation  
 
*  
Acute/subacute can also be replaced by early stent thrombosis. Early stent thrombosis 
(0 - 30 days) - this definition is currently used in the community.  
† 
Including “primary” as well as “secondary” late stent thrombosis; “secondary” late 
stent thrombosis is a stent thrombosis after a target segment revascularization.  
 
Categories (Definite, Probable, and Possible): 
 
Definite stent thrombosis 
Definite stent thrombosis is considered to have occurred by either angiographic or 
pathologic confirmation. 
 
 
Angiographic confirmation of stent thrombosis* 
The presence of a thrombus† that originates in the stent or in the segment 5 mm 
proximal or distal to the stent and presence of at least 1 of the following criteria 
within a 48-hour time window:  
• Acute onset of ischemic symptoms at rest  
• New ischemic ECG changes that suggest acute ischemia  
• Typical rise and fall in cardiac biomarkers (refer to definition of spontaneous 
MI)  
• Non-occlusive thrombosis 
o Thrombus Intracoronary thrombus is defined as a (spheric, ovoid, or 
irregular) non-calcified filling defect or lucency surrounded by contrast 
material (on 3 sides or within a coronary stenosis) seen in multiple 

Abbott Vascular 
Version 3.0 
XIENCE 90 Protocol #16-308-Redacted 
 
May 25, 2018 
 
 
 
projections, or persistence of contrast material within the lumen, or a 
visible embolization of intraluminal material downstream.  
• Occlusive thrombus  
o TIMI 0 or TIMI 1 intrastent or proximal to a stent up to the most 
adjacent proximal side branch or main branch (if originates from the 
side branch).  
 
Pathological confirmation of stent thrombosis  
Evidence of recent thrombus within the stent determined at autopsy or via 
examination of tissue retrieved following thrombectomy.  
 
    * 
The incidental angiographic documentation of stent occlusion in the absence 
of clinical signs or symptoms is not considered a confirmed stent thrombosis 
(silent occlusion). 
 
    † 
Intracoronary thrombus. 
 
Probable stent thrombosis 
Clinical definition of probable stent thrombosis is considered to have occurred after 
intracoronary stenting in the following cases: 
• Any unexplained death within the first 30 days‡  
• Irrespective of the time after the index procedure, any MI that is related to 
documented acute ischemia in the territory of the implanted stent without 
angiographic confirmation of stent thrombosis and in the absence of any other 
obvious cause  
 
    ‡ 
For studies with ST-elevation MI population, one may consider the exclusion 
of unexplained death within 30 days as evidence of probable stent thrombosis. 
 
Possible stent thrombosis 
Clinical definition of possible stent thrombosis is considered to have occurred with any 
unexplained death from 30 days after intracoronary stenting until end of trial follow-up. 
 
STROKE 
 
An acute symptomatic episode of neurological dysfunction attributed to a vascular cause 
lasting more than 24 hours or lasting 24 hours or less with a brain imaging study or autopsy 
showing new infarction. 
• Ischemic Stroke: An acute symptomatic episode of focal cerebral, spinal, or retinal 
dysfunction caused by an infarction of central nervous system tissue. 
• Hemorrhagic Stroke: An acute symptomatic episode of focal or global cerebral or 
spinal dysfunction caused by a non-traumatic intraparenchymal, intraventricular, or 
subarachnoid hemorrhage. 
• Undetermined Stroke: A stroke with insufficient information to allow categorization 
as ischemic or hemorrhagic. 
 
Note: an event that last < 24 hours may be adjudicated as a stroke if the following treatments 
were used: 
• Pharmacologic, i.e., thrombolytic drug administration, or 
Non-pharmacologic, i.e., neurointerventional procedure (e.g., intracranial angioplasty)

BLEEDING (Per BARC, Circulation 2011; 123: 2736-2747) 
Bleeding will also be adjudicated per Bleeding Academic Research Consortium (BARC) 
definitions: 
• Type 0: no bleeding 
• Type 1: bleeding that is not actionable and does not cause the patient to seek 
unscheduled performance of studies, hospitalization, or treatment by a healthcare 
professional; may include episodes leading to self-discontinuation of medical therapy 
by the patient without consulting a healthcare professional 
• Type 2: any overt, actionable sign of hemorrhage (eg, more bleeding than would be 
expected for a clinical circumstance, including bleeding found by imaging alone) that 
does not fit the criteria for type 3, 4, or 5 but does meet at least one of the following 
criteria: (1) requiring nonsurgical, medical intervention by a healthcare professional, 
(2) leading to hospitalization or increased level of care, or (3) prompting evaluation 
• Type 3 
o Type 3a 
 Overt bleeding plus hemoglobin drop of 3 to < 5 g/dL* (provided 
hemoglobin drop is related to bleed) 
 Any transfusion with overt bleeding 
o Type 3b 
 Overt bleeding plus hemoglobin drop ≥ 5 g/dL*(provided hemoglobin 
drop is related to bleed) 
 Cardiac tamponade 
 Bleeding requiring surgical intervention for control (excluding 
dental/nasal/skin/hemorrhoid) 
 Bleeding requiring intravenous vasoactive agents 
o Type 3c 
 Intracranial hemorrhage (does not include microbleeds or hemorrhagic 
transformation, does include intraspinal) 
 Subcategories confirmed by autopsy or imaging or lumbar puncture 
 Intraocular bleed compromising vision 
• Type 4: CABG-related bleeding 
o Perioperative intracranial bleeding within 48 h 
o Reoperation after closure of sternotomy for the purpose of controlling 
bleeding 
o Transfusion of ≥ 5 U whole blood or packed red blood cells within a 48-h 
period† 
o Chest tube output ≥ 2L within a 24-h period 
• Type 5: fatal bleeding 
o Type 5a 
 Probable fatal bleeding; no autopsy or imaging confirmation but 
clinically suspicious 
o Type 5b 
 Definite fatal bleeding; overt bleeding or autopsy or imaging 
confirmation

CABG indicates coronary artery bypass graft. Platelet transfusions should be recorded 
and reported but are not included in these definitions until further information is obtained 
about the relationship to outcomes. If a CABG-related bleed is not adjudicated as at least 
a type 3 severity event, it will be classified as not a bleeding event. If a bleeding event 
occurs with a clear temporal relationship to CABG (i.e., within a 48-h time frame) but 
does not meet type 4 severity criteria, it will be classified as not a bleeding event. 
* Corrected for transfusion (1 U packed red blood cells or 1 U whole blood=1 g/dL 
hemoglobin). 
† Cell saver products are not counted. 
 
 
REVASCULARIZATION (Per ARC Circulation 2007; 115: 2344-2351) 
 
Target Lesion Revascularization (TLR)  
TLR is defined as any repeat percutaneous intervention of the target lesion or bypass surgery 
of the target vessel performed for restenosis or other complication of the target lesion. All 
TLR should be classified prospectively as clinically indicated [CI] or not clinically indicated 
by the investigator prior to repeat angiography. The target lesion is defined as the treated 
segment from 5 mm proximal to the stent and to 5 mm distal to the stent. 
Target Vessel Revascularization (TVR) 
TVR is defined as any repeat percutaneous intervention or surgical bypass of any segment of 
the target vessel. The target vessel is defined as the entire major coronary vessel proximal and 
distal to the target lesion which includes upstream and downstream branches and the target 
lesion itself  
Non Target Lesion Revascularization (Non-TLR) 
Any revascularization in the target vessel for a lesion other than the target lesion is 
considered a non-TLR. 
Non Target Vessel Revascularization (Non-TVR) 
Revascularization of the vessel identified and treated as the non-target vessel at the time of 
the index procedure.  
Clinically Indicated [CI] Revascularization (TLR/TVR) 
A revascularization is considered clinically indicated if angiography at follow-up shows a 
percent diameter stenosis ≥ 50% and if one of the following occurs:  
• A positive history of recurrent angina pectoris, presumably related to the target vessel;  
• Objective signs of ischemia at rest (ECG changes) or during exercise test (or 
equivalent), presumably related to the target vessel;  
• Abnormal results of any invasive functional diagnostic test (e.g., Doppler flow 
velocity reserve, fractional flow reserve);  
• A TLR/TVR with a diameter stenosis ≥70% in the absence of the above mentioned 
ischemic signs or symptoms. 
 
TARGET LESION FAILURE (TLF) 
TLF is defined as a composite of all cardiac death, myocardial infarction attributed to target 
vessel or clinically-indicated TLR.

TIMI (THROMBOSIS IN MYOCARDIAL INFARCTION) FLOW GRADES  
0. No contrast flow through the stenosis. 
 
 
1. A small amount of contrast flows through the stenosis but fails to fully opacify the 
artery beyond. 
2. Contrast material flows through the stenosis to opacify the terminal artery segment. 
However, contrast enters the terminal segment perceptibly more slowly than more 
proximal segments. Alternatively, contrast material clears from a segment distal to a 
stenosis noticeably more slowly than from a comparable segment not preceded by a 
significant stenosis. 
3. Anterograde flow into the terminal coronary artery segment through a stenosis is as 
prompt as anterograde flow into a comparable segment proximal to the stenosis. 
Contrast material clears as rapidly from the distal segment as from an uninvolved, 
more proximal segment.
