Assessment of the Carillon® Mitral Contour System® in Treating Functional Mitral Regurgitation Associated With Heart Failure - The CARILLON Trial

The objective of this prospective, multi-center, randomized, double-blind trial is to assess
the safety and efficacy of the CARILLON Mitral Contour System in treating subjects with
functional mitral regurgitation (FMR) associated with heart failure, compared to a randomized
Control group which is medically managed according to heart failure guidelines.

A total of 450 subjects will be randomized at up to 75 investigational sites in the United
States, Canada, Europe and Australia. Subjects will be randomized into one of two study
groups using a 2:1 (Intervention : Control) ratio.

Study subjects who are eligible for this clinical study will undergo a transthoracic
echocardiographic examination prior to randomization to evaluate the inclusion criteria
associated with the severity of mitral regurgitation. A coronary angiogram will also be
performed to evaluate the coronary artery anatomy as a final eligibility (screening)
assessment. Subjects who meet all eligibility criteria will be randomized into one of two
study groups (Intervention or Control).

Study subjects will undergo a venogram to assess the suitability of the coronary sinus/great
cardiac vein (CS/GCV) for placement of the CARILLON implant. If the subject meets the
anatomic requirements for device placement, the subject will be randomized.

Subjects randomized to the Intervention group will undergo the CARILLON implant procedure.
With the distal aspect of the device anchored, incremental tension will be applied to plicate
the peri-annular tissue. A transesophageal or transthoracic echocardiogram will be obtained
before, during and after device placement to quantitate the degree of functional mitral
regurgitation and to evaluate left ventricular function. After the proximal anchor of the
implant is locked in place, safety and efficacy will be reconfirmed prior to releasing the
CARILLON implant from the delivery system.

Subjects randomized to the Control group will experience an index procedure similar to the
Intervention group (without device placement) to ensure that they will not be able to deduce
the group assignment based on the type of intervention or time associated with the procedure.

After the study subjects are discharged, the subjects' primary care specialists
(cardiologist/heart failure physician) and clinical investigation site staff will coordinate
follow-up evaluations. Subjects will be evaluated at one (1), six (6), twelve (12), eighteen
(18) and twenty-four (24) months post-randomization, to assess long-term safety, and
functional and clinical status.

After the 12-month evaluation, all subjects will be unblinded. Control subjects and
Intervention subjects who were not implanted with CARILLON (e.g., due to venous dissection or
other procedural complication - "Non-Implanted"), may be offered the option to receive the
CARILLON device, as part of a Cross-Over Registry, at the discretion of the study physician
and patient.

All Intervention and Control subjects will be followed with an abbreviated annual contact for
an additional three (3) years, for a total of five (5) years.

Inclusion Criteria:

1. Diagnosis of ischemic or non-ischemic cardiomyopathy

2. Symptomatic functional (secondary) mitral regurgitation defined as both: - 2+
(Moderate), 3+ (Moderate/Severe), or 4+ (Severe).

Note: 4+ can only be included if multidisciplinary site assessment (including a
surgeon) determines that surgery is not necessary within the 1-year follow-up period
for this study.

5. Left Ventricular Ejection Fraction ≤ 50%

1. Subjects with LVEF ≤ 40% have no additional restrictions

2. Subjects with LVEF > 40% and ≤ 50%

- MR grade 3+ or 4+ can only be included if the baseline NYHA is class III or
IV

- MR grade 2+ (at rest) can only be included if the baseline NYHA is class III
or IV AND left atrial volume > 48mm/m2 (normalized to body surface area)

6. LVEDD ≤ 70 mm, or LVEDD / BSA ≤ 4.0 cm/m2 Note: As assessed by Imaging Core
Laboratory.

7. Guideline directed heart failure medication regimen. This minimally includes:

- On ACE inhibitor (ACE-I) for three (3) months with stable dosage for one (1)
month (with documentation as to why this is the maximally tolerated medication,
or achieving the mean dose as described in the ACCF/ AHA guidelines

1. This also includes an Angiotensin II Receptor Blocker (ARB) at stable doses
for one (1) month prior to subject registration in the trial, if tolerated,
when ACE-I is not tolerated.

(valsartan/sacubitril) is an acceptable Class I acceptable alternative for
use in patients with HFrEF.34

- On a beta-blocker for three (3) months with stable dosage for one (1) month (with
documentation as to why this is the maximally tolerated medication, or achieving
the mean dose as described in the ACCF/ AHA guidelines

- On a diuretic for three (3) months
