Trial summary

In this study, the investigators hypothesize that the addition of antioxidant BMX-010 to perfusion solution, digestion solution and culture medium during islet isolation process, can lead to greater preservation of islet mass and metabolic function, such as improved islet yield, viability, and functional potency.

About this study

Official title: Manganese Porphyrin MnTE-2-PyP (BMX - 010) Preservation of Islet Cell Mass and Function for Clinical Islet Transplantation

In this study, the investigators hypothesize that the addition of antioxidant BMX-010 to perfusion solution, digestion solution and culture medium during islet isolation process, can lead to greater preservation of islet mass and metabolic function, such as improved islet yield, viability, and functional potency.

This pilot study will involve up to 10 participants from the islet transplant waiting list at the Clinical Islet Transplant Program. All participants will receive islets isolated with the medication BMX-010. This is to assess the primary safety of BMX-010 on pancreata and islets. BMX-010 will be used only in the islet isolation process, and will not be given to participants as medication.

Read the detailed description

Islet Transplantation is a procedure used in people with difficult to control Type 1 Diabetes. Insulin producing cells (islets) are isolated from a deceased donor pancreas. After the cells are carefully isolated from the donor pancreas, the islets are transplanted into the recipient's liver. These transplanted islets may produce insulin.

One of the challenges with islet transplant is the death of some of the islet cells during isolation and storage while awaiting transplant. This is caused, in part, by inflammation and "oxidization" of the islet tissue. Oxidization is a process that causes chemical stress on living cells. We are looking for medications that would reduce inflammation, reduce oxidization and minimize cell death during the isolation process.

BMX-010 is a new drug that we believe will help fight oxidization. It is an antioxidant that has been shown in lab studies to help islet cells survive isolation and keep them healthy and functioning. BMX-010 has not been used in human islet transplants in Canada before this study. BMX-010 has been used once in a patient who needed his pancreas removed - the islets were isolated and treated with BMX-010, then transplanted back into the patient (auto-islet transplant). These results are promising and there have been no significant side-effects reported. There have also been studies using human islets, treated with BMX-010, transplanted into mice.

In this study, 10 patients will receive islets treated with BMX-010. This is to assess the primary safety of BMX-010 on pancreata and islets. For pancreata and islets treated with BMX-010, BMX-010 will be added in the steps of pancreas perfusion, pancreas digestion and islet culturing. Participants in the study will receive their islet transplants under standard of care islet transplant for all aspects of peri- and post-transplant management including immunosuppression. Islet transplant patients are followed as part of their standard of care, therefore the data collected for this study will be measured as part of routine clinical care, requiring no extra study specific clinic visits. We will review data collected up to day 30 post-transplant and will include the following: patient and graft survival data, biochemical data from routine blood work, routine and for cause imaging, metabolic testing, initiation of interventions to treat complications, and reporting of any adverse or serious adverse events.

What is being measured

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

  1. Islet yield using BMX-010, compared to current standard islet isolation data

    To assess the safety of treating pancreata using BMX-010 prior to islet transplantation, treated islet isolation data will be measured and recorded, compared to current standard islet isolation data.

    Measured: Day -1 pre-transplant (Islet yield will be recorded as standard-of-care routine practice)

Secondary outcomes (2)
  1. Islet isolation quantity and quality using BMX-010, compared to current standard islet isolation data

    To demonstrate efficacy of BMX-010 to improve islet isolation quantity and quality prior to islet transplantation, treated islet isolation data will be measured and recorded, compared to current standard islet isolation data.

    Measured: Day -1 pre-transplant (Islet isolation quantity and quality will be recorded as standard-of-care routine practice)

  2. AE/SAE morbidity within 1 month post-transplant

    To demonstrate safety of BMX-010 in islet transplantation, Adverse Event/Serious Adverse Event morbidity within 1 month post-transplant will be recorded.

    Measured: up to 1 month post-transplant

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Islet isolation using BMX-010 in people with Type 1 Diabetes, run by University of Alberta at 1 site in Canada.

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 4 inclusion and 24 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: finished, as of the sponsor's last update on 11 May 2022. 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 Canada. 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?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Islet yield using BMX-010, compared to current standard islet isolation data (time frame: Day -1 pre-transplant (Islet yield will be recorded as standard-of-care routine practice)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 11 May 2022.
