About this study

The purpose of this project is to compare the effect of oxygenated preservation of the pancreas before transplantation using the "Two-Layer Method" (TLM) against outcomes previously experienced with organs preserved using only standard University of Wisconsin (UW) storage solution. It is our hypothesis that TLM preservation will reduce the frequency and severity of complications of pancreas transplantation, increase the number of organs acceptable for transplantation, and spare individual patients and their families suffering and hardship.

Read the detailed description

Two-Layer Method (TLM) preservation consists of a storage chamber containing a layer of highly oxygenated, water-immiscible liquid perfluorocarbon (perfluorodecalin, C10F18) surmounted by a layer of conventional UW (or similar) organ preservation solution. The perfluorocarbon is sufficiently dense (~2 g/ml) that the pancreas floats on top of it, in contact with both layers. The perfluorocarbon combines low toxicity with an oxygen content 75 times greater than the UW solution used in standard pancreas storage. When preserved under these conditions, the pancreas absorbs oxygen by diffusion and steadily consumes it, supporting sufficient aerobic metabolism to maintain tissue ATP concentrations at near-physiologic levels and prevent, or even reverse, pancreas anoxic injury. In animal models of pancreas ischemic and storage injury, TLM preservation has been strikingly successful at improving the outcome of both islet isolation and pancreas transplantation.

    Also called pancreas preservation

    Preserving the pancreas before transplantation in an oxygenated system containing highly oxygenated liquid perfluorocarbon (perfluorodecalin, C10F18.

When preserved under these conditions, the pancreas absorbs oxygen by diffusion and steadily consumes it, supporting sufficient aerobic metabolism to maintain tissue ATP concentrations at near-physiologic levels and prevent, or even reverse, pancreas anoxic injury.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Post-transplantation adverse event frequency

    Post-transplantation adverse event frequency (graft thrombosis, hemorrhage, peri-pancreatic abscess, re-laparotomy, cadaver duodenum leak, pseudo-aneurysm formation, rejection, graft failure, patient death)

    Measured: 1 year

Secondary outcomes (1)
  1. Standard post-transplantation morbidity endpoints

    Standard post-transplantation morbidity endpoints including fungal, bacterial, and viral infections, and incidence and rate of stroke and heart attack. Length of hospital stay and re-admission and re-operation rates will also be monitored.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Two-Layer Method pancreas preservation system drug and Two-Layer Method pancreas preservation system device in people with Graft Pancreatitis, run by University of Nebraska at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 4 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Logistic problems with adequately timely organ collection and transport). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Post-transplantation adverse event frequency (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00592280, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Dec 2023.
