“A procedure for Stem Cell Educator therapy in which a patient’s blood is circulated through a closed-loop system that separate lymphocytes from the whole blood and briefly co-cultures them with adherent CB-SCs before returning them to the patient’s circulation. In an open-label, phase1/phase 2 study, patients (n = 15) with T1D received one treatment with the Stem Cell Educator. Median age was 29 years (range, 15 to 41), and median diabetic history was 8 years (range, 1 to 21).”
Stem Cell Educator therapy was well tolerated and can markedly improve C-peptide levels, reduce the median glycated hemoglobin A1C (HbA1C) values, and decrease the median daily dose of insulin in patients with some residual beta cell function (n = 6) and patients with no residual pancreatic islet beta cell function (n = 6). Treatment also produced an increase in basal and glucose-stimulated C-peptide levels through 40 weeks.
