Trial to Compare the SherpaPak™ Device vs Cold Storage (SherpaPak)

February 1, 2025 updated by: Fardad Esmailian, Cedars-Sinai Medical Center

Randomized Trial to Compare the SherpaPak™ Device vs Cold Storage of Donor Hearts in Transplantation: A Pilot Study

The Investigator's are doing this study to see which method of organ preservation leads to better outcomes for donated hearts.

There are two methods of organ preservation. The first method is the use of cold storage. With this method, the donor heart is stored in preservation fluid within bags that are then placed on ice and transported in a cooler. This is the usual method for transporting donor hearts. This is also known as "standard of care."

The second method is the use of the SherpaPak™ Cardiac Transport System. With this method, the donor heart is kept at a steady, consistent temperature throughout transportation. This method is not typically used for transporting donor hearts.

The study will include up to 20 people in total.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a randomized study and has 2 study groups. Participants will be randomly assigned to a group in a 1:1 ratio.

  • 50% chance of receiving a donor heart using the SherpaPak™ method, or
  • 50% chance of receiving a donor heart using the cold storage method.

The research team will analyze data from the medical records from the heart transplant and clinic visits up to 30 days after the heart transplant. Participants will be in the study for about 30 days.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Absence of Moderate to Severe Primary Graft Dysfunction (Left or Right Ventricle)
Time Frame: 24 hours post-transplant
Percentage of subjects without moderate to severe primary graft dysfunction (left or right ventricle)

30-day Post-transplant Survival
Time Frame: 30 day post heart transplant (htx)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Vasoactive-Inotropic Score
Time Frame: 24 hours post-transplant

Vasoactive inotropic scores (VIS) are used to measure the amount of cardiovascular support a patient is receiving at certain time point, for our study it was at 24hrs post transplant. Below is the calculation for the score.

VIS = dopamine (µg/kg/min) + dobutamine (µg/kg/min) + 100 × epinephrine (µg/kg/min) + 100 × norepinephrine (µg/kg/min) + 10 × milrinone (µg/kg/min) + 10,000 × vasopressin (units/kg/min) + 50 × levosimendan (µg/kg/min).

The minimum score is 0 if the patient does not require any support but there really isn't a maximum score as theoretically patients can be on any range of support. Higher values indicates that a patient is requiring a higher cardiovascular support at 24 hrs.

VIS = dopamine (µg/kg/min) + dobutamine (µg/kg/min) + 100 × epinephrine (µg/kg/min) + 100 × norepinephrine (µg/kg/min) + 10 × milrinone (µg/kg/min) + 10,000 × vasopressin (units/kg/min) + 50 × levosimendan (µg/kg/min)
