EVOLVE Short DAPT Study

The primary objective of the EVOLVE Short DAPT Study is to assess the safety of 3-month dual
antiplatelet therapy (DAPT) in subjects at high risk for bleeding undergoing percutaneous
coronary intervention (PCI) with the SYNERGY Stent System.

The study will be conducted up to 120 sites worldwide in the United States, Europe, Japan,
and Brazil with planned enrollment of up to 2,250 subjects. Clinical follow-up will be
required at the following time points: 3 months, 6 months, 12 months and 15 months post index
procedure.

Subjects must be treated with one of the following P2Y12 inhibitors (clopidogrel, prasugrel,
or ticagrelor) for 3 months following the index procedure. Subjects must be treated with
aspirin for the duration of the trial. The minimum daily maintenance dose of aspirin should
be 75-100 mg.

Subjects are eligible for discontinuation of P2Y12 inhibitor at 3 months if they meet both of
the following criteria: subject was treated with 3 months of study required antiplatelet
therapy post index procedure; and subject was free from events (stroke, MI, PCI, coronary
artery bypass graft [CABG], and stent thrombosis) between the index procedure and the 3 month
visit.

Subjects are not eligible for discontinuation of P2Y12 inhibitor at 3 months if any of the
following criteria are met: subject who experiences a stroke, MI, PCI, CABG and/or stent
thrombosis, during the 0-3 month period (between the date of the index procedure and the date
of the 3-month follow-up visit); or subject who is non-compliant with study required
antiplatelet therapy during the 0-3 month period (between the date of the index procedure and
the date of the 3-month follow-up visit); or subject judged inappropriate for discontinuation
from P2Y12 inhibitor use at 3 months due to another condition requiring chronic P2Y12
inhibitor use.

All enrolled subjects who receive a SYNERGY stent must be followed at all milestones through
15-months, regardless of eligibility to discontinue P2Y12 inhibitor. Following the 3-month
milestone, subjects who experience MI or stent thrombosis events should be treated per the
investigator's discretion and should be followed through the 15-month visit.

Inclusion Criteria:

1. Subject is considered at high risk for bleeding, defined as meeting one or more of the
following criteria at the time of enrollment:

- ≥ 75 years of age and, in the opinion of the investigator, the risk of major
bleeding associated with >3 months of DAPT outweighs the benefit,

- need for chronic or lifelong anticoagulation,

- history of major bleeding (severe/life threatening or moderate bleeding based on
the GUSTO classification) within 12 months of the index procedure,

- history of stroke (ischemic or hemorrhagic),

- renal insufficiency (creatinine ≥2.0 mg/dl) or failure (dialysis dependent),

- platelet count ≤100,000/μL

2. Subject must be at least 18 years of age

3. Subject must have had implantation of at least one SYNERGY stent within the preceding
3 calendar days

4. Subject must be able to take study required antiplatelet therapy (as required per
protocol)

5. Subject is willing to comply with all protocol requirements, including agreement to
stop taking P2Y12 inhibitor at the 3-month milestone, if eligible per protocol

6. Subject (or legal guardian) understands the trial requirements and the treatment
procedures and provides written informed consent before any study-specific procedures
are performed

7. For subjects less than 20 years of age enrolled at a Japanese site, the subject/ the
subject's legal representative must provide written informed consent before any
study-specific tests or procedures are performed

Exclusion Criteria:

1. Subject with an indication for the index procedure of acute ST elevation MI (STEMI)

2. Subject with an indication for the index procedure of Non ST elevation MI (NSTEMI),
based on the 3rd Universal MI definition

3. Subject with treatment with another coronary stent, other than SYNERGY, during the
index procedure

4. Subject with planned staged procedures. (Note: Planned staged procedures are allowed
if performed within 7 days and with only SYNERGY stents).

5. Subject has a known allergy to contrast (that cannot be adequately pre-medicated), the
SYNERGY stent system or protocol-required concomitant medications (e.g., everolimus or
structurally related compounds, polymer or individual components, all P2Y12 inhibitors
and aspirin)

6. Subject with implantation of a drug-eluting stent within 9 months prior to index
procedure

7. Subject previously treated at any time with intravascular brachytherapy

8. Subject has an active peptic ulcer or active gastrointestinal (GI) bleeding

9. Subject is participating in an investigational drug or device clinical trial that has
not reached its primary endpoint (Note: registry, observational, data collection
studies are not exclusionary)

10. Subject intends to participate in an investigational drug or device clinical trial
within 15 months following the index procedure (Note: registry, observational, data
collection studies are not exclusionary)

11. Subject judged inappropriate for discontinuation from P2Y12 inhibitor use at 3 months,
due to another condition requiring chronic P2Y12 inhibitor use

12. Subject with planned surgery or procedure necessitating discontinuation of P2Y12
inhibitor within 3 months following index procedure
