Infusion of Allogeneic Stromal Mesenchymal Stem Cells From Wharton´s Jelly in Patients With Diffuse Cutaneous Systemic Sclerosis With Refractory Pulmonary Involvement to Treatment

Phase 1 NCT07542067 Kind: PHASE1 Apr 21, 2026

Abstract

Progressive SSc is an entity with limited therapeutic alternatives and a survival rate of less than 45% within the first 3 to 5 years. The disease causes severe limitations in quality of life, ranging from functional impairment to depression. Up to 20% of patients become refractory to conventional treatment with disease-modifying anti-rheumatic drugs (DMARDs) and cyclophosphamide therapy. This condition favors progression to visceral involvement, including gastrointestinal, pulmonary, and pulmonary hypertension manifestations. The latter, considered a poor prognostic factor, increases mortality in this patient population and drastically affects quality of life. For this reason, different therapeutic options have been considered, including cell transplantation and stem cell use.

Among the options studied to date are stromal mesenchymal cells derived from Wharton's jelly. These cells have been administered via intravenous infusion or direct application in various disease scenarios, ranging from vascular involvement to interstitial lung disease and pulmonary hypertension, with promising results in terms of clinical progression, quality of life improvement, and prognostic indices. This therapy has demonstrated a favorable safety profile at the time of administration and a low rate of adverse events, with self-limiting fever being the most frequent event.

Based on the above and considering the possibility of offering patients without therapeutic alternatives for the disease, ...
