About this study

Official title: An Open Label, Parallel Single Centre Trial of Wharton's Jelly Derived Allogeneic Mesenchymal Stromal Cells Repeated Treatment to Preserve Endogenous Insulin Production in Adult Patients Diagnosed with Type 1 Diabetes

An open label, parallel single centre trial of Wharton's Jelly derived allogenic mesenchymal stromal cells repeated treatment to preserve endogenous insulin production in adult patients diagnosed with type 1 diabetes

Read the detailed description

This is a phase (I)/II study, and the purpose of this study is to determine whether, in adult patients diagnosed for type 1 diabetes, a repeated allogeneic infusion of WJMSCs is safe and to study changes in beta-cell function, metabolic control and Diabetes Treatment Satisfaction. The study population will consist of 15 adult male patients, 18-41 years of age (inclusive at both ends) diagnosed (<3,5 years) with type 1 diabetes mellitus.

What is being measured

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

  1. The primary endpoint in this study is; safety parameters include adverse events and hypoglycemia, allergic reactions, ophthalmologic examination, ECG, vital signs, laboratory assessments.

    To investigate the safety and tolerance after a repeated allogeneic infusion of Whartons Jelly Mesenchymal Stromal Cells (WJMSCs) intravenously in adult patients diagnosed with type 1 diabetes after one year following the repeated treatment.

    Measured: 372 days

  2. Delta-change of C-peptide AreaUnder the Curve (AUC) (0-120 min) for Mixed Meal Tolerance Test (MMTT) at day 372 following WJMSC infusion when compared to test performed before start of treatment when compared to control patients.

    To study changes in insulin requirements during one year following treatment .

    Measured: 372 days

Secondary outcomes (9)
  1. Number of patients insulin independent (ADA criteria) at day 372.

    To study changes in insulin requirements during one year following treatment .

    Measured: 372 days

  2. Number of patients with daily insulin needs <0.25U/kg at day 372.

    To study changes in insulin requirements during one year following treatment .

    Measured: 372 days

  3. Insulin requirement/kg BW at day 372. HbA1c at day 372.

    To study changes in insulin requirements during one year following treatment .

    Measured: 372 days

  4. HbA1c at day 372

    To study changes in HbA1c during one year following treatment.

    Measured: 372 days

  5. Glucose variability (mean amplitude of glycaemic excursions and glycaemic lability index) duration derived from the continuous glucose monitoring system® at day 372

    To study changes in glucose levels during one year following treatment.

    Measured: 372 days

  6. Delta change of levels of fasting C-peptide at day 372 when compared to test before start of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing ProTrans in people with Type1diabetes, run by NextCell Pharma Ab at 1 site in Sweden.

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 6 inclusion and 16 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 7 Mar 2025. 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 Sweden. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

The primary endpoint in this study is; safety parameters include adverse events and hypoglycemia, allergic reactions, ophthalmologic examination, ECG, vital signs, laboratory assessments. (time frame: 372 days). The study lists 2 primary outcomes in all. 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 7 Mar 2025.
