About this study
Official title: Safety of Cultured Allogeneic Adult Umbilical Cord Derived Mesenchymal Stem Cell Intravenous Infusion for the Treatment of Systemic Sclerosis
This trial will study the safety and efficacy of intravenous infusion of cultured allogeneic adult umbilical cord derived mesenchymal stem cells for the treatment of Systemic Sclerosis
Read the detailed description
Studies have shown that stem cell treatment is safe and efficacious for the treatment of Systemic Sclerosis. Patients with Systemic Sclerosis will receive a single intravenous infusion of cultured allogeneic adult umbilical cord derived mesenchymal stem cells. The total dose will be 100 million cells. Patients will be evaluated within one month pre treatment and at 1, 6, 12, 24, 36, and 48 months post treatment for safety and efficacy.
For patients with more severe disease requiring chemotherapeutic drugs such as methotrexate, an autologous T Cell vaccine will be utilized created from the patient's own T cells obtained by apheresis.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing AlloRx in people with Systemic Sclerosis, run by The Foundation for Orthopaedics and Regenerative Medicine at 2 sites in 2 countries.
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 2 inclusion and 10 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 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Antigua and Barbuda, Argentina. 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 was stopped early (reason given: Inadequate treatment response observed in preliminary data did not justify enrolling further study participants). 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?
Safety (adverse events) (time frame: Four year follow-up). 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 NCT05016804, which also lists 3 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 20 Oct 2026.
