About this study

Systemic sclerosis (SSc) is a rare, severe and chronic systemic autoimmune disease (AD) characterized by vasculopathy, immune dysregulation and fibrosis leading to multi-organ dysfunction (primarily skin, lungs, heart gastrointestinal tract and kidneys), with high morbidity and mortality, altered health-related quality of life, all at high cost for patients and society.

Treatment are mostly symptomatic and only autologous hematopoietic stem cell transplantation (AHSCT) has shown long term improvement in overall and event-free survival with disease-modifying properties. However, AHSCT is contra-indicated in case of advanced visceral involvement and in eligible patients, it is still associated with risk of toxicity. There is an urgent need to identify safe and effective treatments for severe SSc.

Read more

Mesenchymal stromal cells (MSC) are multipotent cells which carry immunomodulatory, pro-angiogenic and anti-fibrotic properties, that can target 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 have previously a) shown disease-specific abnormalities in MSC(M) from SSc patients, providing strong rationale to use allogeneic MSC to treat SSc patients, b) published 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.

Considering the above rationale, we hypothesize that use of healthy donors allogeneic MSC(AT) produced by Etablissement Français du Sang (EFS) will demonstrate a) no safety issues, b) an efficacy profile that will increase with repeated infusion of allogeneic MSC(AT) to treat SSc.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing 2 infusions of MSC and 1 infusion of MSC in people with Severe 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 15 inclusion and 14 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: opening soon, as of the sponsor's last update on 9 Dec 2024. 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. Some participants in this study may receive a placebo. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Dominique Farge, MD PhD (0142499764 ext. +33, 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?

Rate of treatment-related Serious Adverse Events (time frame: After each infusion). 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 9 Dec 2024.
