About this study

Mesenchymal stromal cells (MSC) are multipotent cells which carry immunomodulatory, pro-angiogenic and anti-fibrotic properties, that can target Systemic Sclerosis (SSc) pathogenesis and its clinical manifestations. The increasing use of MSC, harvested from bone marrow (MSC(M)), adipose tissue (MSC(AT)), or umbilical cord (MSC(UC)) in a variety of indications, provides consistent evidence supporting their safety in humans. The efficacy of MSC(M) intravenous (IV) injection for treating acute graft versus host disease led to their marketing approval in 2012 and MSC(AT) (Alofisel) were approved for severe Crohn's fistula in 2018.

MSC represent a promising therapeutic approach for SSc. We previously a) showed disease-specific abnormalities in MSC(M) from SSc patients, providing strong rationale to use allogeneic MSC to treat SSc patients, b) completed the first phase I/II dose escalation trial using allogenic MSC(M) infusion in 20 severe SSc patients (ClinicalTrials.gov: NCT02213705, PHRC AOM 11-250) with no safety issues, significant improvement in skin fibrosis at 3 to 6 months after infusion which appeared lower thereafter, thereby supporting the need for repeated infusions.

In vitro, experimental and clinical studies suggest that MSC properties vary according to their tissue of origin/source. We demonstrated that compared to MSC(M), MSC(AT) are easier to harvest and display higher proliferative capability before entering senescence, higher genetic stability, and superior immunosuppressive properties.

The objective of the present research is the successful production of allogeneic MSC(AT) derived from selected healthy donors, with adequate phenotypic criteria according to the International Society for Cell \& Gene Therapy.

Considering the above rationale, these MSC(AT) will subsequently be used in a Phase I/II randomized clinical trial testing allogeneic MSC(AT) systemic infusion for treatment of severe systemic sclerosis.

Questions about this trial

What is this clinical trial studying?

A study testing Adipose tissue harvesting in people with Mesenchymal Stromal Cell and Systemic Sclerosis, run by Assistance Publique - Hôpitaux de Paris.

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 25 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: status not confirmed, as of the sponsor's last update on 17 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

Results are not available in the source record.

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

Contact Dominique Farge, Pr (+33142499768, dominique.farge-bancel@aphp.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Production of at least 3 batches of MSC(AT) derived from donors adipose tissue (time frame: Up to 2 months). 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 17 Jul 2023.
