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

Brief description of study

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.

Detailed Study Description

A total of 352 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 1:1 (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 as well as a review by a Central Review Committee to determine appropriateness for the implant procedure. On the day of the procedure, a coronary angiogram will be performed to evaluate the coronary artery anatomy and 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 who meet all eligibility criteria will be randomized into one of two study groups (Intervention or Control).

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. 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 24-month evaluation, all subjects will be unblinded. 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. Any additional therapies which are required to treat symptomatic or advancing disease subjects will be reviewed by a Central Review Committee for endpoint evaluation as long as the subject was treated >6months after randomization so that all subjects may remain on the trial for the entire 5 years of follow up.
