TorEx Lung Perfusion System

Evaluation of the TorEx Lung Perfusion System in Clinical Lung Transplantation: A Safety Study

Lung transplantation is a life-saving and life-prolonging therapy for patients with end-stage lung disease. However, the number of patients listed for lung transplantation exceeds the number of available donor lungs, leading to long wait times, deterioration in health and death of some listed patients. One way to address this issue is to reduce the number of donor lungs that are deemed unusable (declined) for transplantation. Often, donor lungs are declined for transplantation based on questionable function or inability to fully assess the organ in the donor. Due to this reason, up to 80% of potentially suitable lungs may be discarded. As a result, ex vivo lung perfusion (EVLP) was developed.

EVLP is a technique that enables the donor lungs to function in near physiological conditions outside the body, allowing surgeons to evaluate the suitability of the donor lungs for transplantation. Using this technique, centers have reported the recovery of around 70% of donor lungs that would have otherwise been deemed unusable and discarded.

The first generation Toronto EVLP technique started as a clinical trial in 2008 and became a part of the clinical standard of care at Toronto General Hospital in 2011. Since then, many clinical studies have shown that short- and long-term outcomes of recipients who received donor lungs assessed by the Toronto EVLP system were similar to those who received donor lungs deemed suitable to go straight to transplantation.

In partnership with Traferox Technologies Inc., surgeons and research team members developed the second generation TorEx Lung Perfusion System, which addresses engineering design limitations of the original Toronto EVLP system. It optimizes the Toronto EVLP technique by combining all the necessary equipment required to perform the procedure, while placing their controls within a central location. The technique of perfusion and ventilation as well as the perfusate solution remain the same between the two EVLP systems. Prior to this study, the TorEx Lung Perfusion System has not been used in clinical human lung transplantation.

The first purpose of this study is to look at the safety of using the TorEx Lung Perfusion System in 20 consented recipients. The second purpose to compare post-transplant outcomes between recipients who received donor lungs assessed by the TorEx Lung Perfusion System and a historical cohort of recipients who received donor lungs that were assessed by the first generation Toronto EVLP system.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
20

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

14 years to 76 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Donor lungs assessed using TorEx Lung Perfusion System
Device: TorEx Lung Perfusion System
When donor lungs with clinical indication for EVLP are allocated to consented recipients, the lungs will be assessed using the second generation TorEx Lung Perfusion System rather than the first generation Toronto EVLP technique (standard of care).

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.
