Donors After Circulatory Death Heart Trial

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.
ClinicalTrials.gov Identifier: NCT03831048
Recruitment Status : Completed
First Posted : February 5, 2019

Brief Summary:
To evaluate the effectiveness of the OCS Heart System to resuscitate, preserve and assess hearts donated after circulatory death for transplantation to increase the pool of donor hearts available for transplantation.

Condition or disease Intervention/treatment Phase
Heart Transplant Device: OCS Heart System Other: Cold Storage Not Applicable

Detailed Description:
A prospective, randomized and concurrent controlled, non-inferiority pivotal trial in which subjects who receive a DCD donor heart transplant will be compared to subjects who receive a standard criteria donor heart transplant (Standard of Care 1 [SOC1] and Standard of Care 2 [SOC2] - from both randomized and concurrent control groups), adjusting for differences in risk factors.

Preserving and assessing donor after circulatory death hearts for transplant

Active Comparator: Standard of Care Heart Only Other: Cold Storage
Active comparator intervention

Primary Outcome Measures :
  1. Survival [ Time Frame: 6 months ]
    Patient survival 6 months post-transplant

Secondary Outcome Measures :
  1. Utilization rate [ Time Frame: Within 24 hours post-transplant ]
    Utilization Rate, defined as the number of eligible DCD donor hearts that met the warm ischemic time limit above and were instrumented on the OCS Heart System that meet the acceptance criteria for transplantation after OCS Heart preservation divided by the total number of eligible DCD donor hearts that met the warm ischemic time limit above and were instrumented on the OCS Heart System.

Other Outcome Measures:
  1. Patient and graft survival [ Time Frame: 30 days ]
    Patient and graft survival at 30 days post transplant

  2. Patient and graft survival [ Time Frame: 30 days or hospital discharge, if later than 30 days ]
    Patient and graft survival at 30 days and initial hospital discharge, if later than 30 days

  3. Severe heart primary graft dysfunction [ Time Frame: 24 hours post transplant ]
    Severe heart primary graft dysfunction of the left and/or right ventricle, not including rejection of cardiac tamponade

  4. Post transplant Mechanical Circulatory Support (MCS) [ Time Frame: >72 hours immediately post-transplant ]
    Use of post-transplant mechanical circulatory support (LVAD, RVAD, BiVAD) for > 72 hours immediately post-transplant.

  5. Patient survival at 1 year after transplant (collected post-approval) [ Time Frame: One year post-transplant. ]
    Patient survival at 1 year after transplant (collected post-approval); comparison of DCD Heart Transplanted Recipients and SOC Heart Transplant Recipients (SOC1 + SOC2) through UNOS/OPTN database.
