MOre REsponse on Cardiac Resynchronization Therapy With MultiPoint Pacing (MORE-CRT MPP)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02006069
Recruitment Status : Terminated (The steering committee had decided to discontinue enrollment because the interim analysis showed a low probability that the study would meet the primary endpoint. The interim analysis did not demonstrate any safety concerns with activating MPP.)

Brief Summary:
The purpose of this Clinical investigation is to assess the impact of the Multi Point Pacing (MPP) feature at 12 months in the treatment of patients not responding to standard Cardiac Resynchronization Therapy (CRT) after 6 months.

Condition or disease Intervention/treatment Phase
Heart Failure Device: MPP Not Applicable

Detailed Description:
This study is designed as a prospective, randomized, multi-center trial. Data will be collected at enrollment, baseline, implant procedure, patient classification, 6 months and 12 months of follow-up. During the 6-month visit, the patient's response to CRT will be evaluated according to LVESV reduction. Patients with an LVESV reduction of at least 15% will be classified as responders. These patients will terminate their participation in the study and return to the center's standard practice. Patients with an LVESV reduction less than 15% will be classified as non-responders and the MPP feature will be activated according to randomization result and they will be followed until the 12-month visit.

Official Title: MOre REsponse on Cardiac Resynchronization Therapy (CRT) With MultiPoint Pacing (MPP)
Study Start Date : December 2013
Actual Primary Completion Date : May 30, 2021
Actual Study Completion Date : May 30, 2021

Arm Intervention/treatment
Experimental: MPP ON
MPP ON: feature is enabled
Device: MPP

All patients enrolled in the study will be implanted (according to current Guidelines) with an MPP compatible CRT device.

The MPP feature will be evaluated in two study phases. Patients randomized to MPP in Phase I will have MPP programmed per the physician's discretion ("no mandated MPP programming") and patients randomized to MPP in Phase II will have MPP programmed per protocol requirements ("mandated MPP programming").

No Intervention: MPP OFF
MPP OFF: feature not enabled

Primary Outcome Measures :
  1. CRT Response [ Time Frame: Response to CRT after 6 months of MPP ]
    The primary endpoint of this study is evaluated at 12 months after enrollment and it is defined as the percentage of non-responder patients converted to responders after 6 months of MPP feature turned ON compared to baseline, as measured by Left Ventricular End Systolic Volume (LVESV) reduction of at least 15%.

Secondary Outcome Measures :
  1. Reduction of LVESV in acute phase [ Time Frame: Baseline vs 6 Months ]
    Reduction of LVESV between baseline and 6 Months visit

  2. Clinical Composite Score evaluation [ Time Frame: Baseline vs 12 Months ]
    Packer's Clinical Composite Score evaluation between baseline and 12 months and between 6 and 12 months

  3. Reverse LV remodeling [ Time Frame: Baseline vs 12 Months ]
    Evaluation of Reverse LV remodeling, measured as changed in echo values LVESV, LVEDD and LVEF

  4. NYHA Class changes [ Time Frame: Baseline vs 12 Months ]
    Evaluation of NYHA Class changes between Baseline and 12 Months FU

  5. 6MWT changes [ Time Frame: Baseline vs 12 Months ]
    Evaluation of the patient's activity status using 6 Minutes Walking Test changes from baseline to 12 months FU

  6. Patient's QoL score changes (MLWHF, EQ-5D) [ Time Frame: Baseline vs 12 Months ]
    Evaluation of patient's Quality of Life score using Minnesota Living with Heart Failure (MLWHF) and EQ-5D Questionnaires
