Background: Advanced cell therapies with autologous, homologous cells show promise to affect reparative and restorative changes in the chronic kidney disease (CKD) nephron. We present our protocol and preliminary analysis of an IRB-approved, phase I single-group, open-label trial that tests the safety and efficacy of Renal Autologous Cell Therapy (REACT; NCT 04115345) in adults with congenital anomalies of the kidney and urinary tract (CAKUT). Methods: Adults with surgically corrected CAKUT and CKD stages 3 and 4 signed an informed consent and served as their “own” baseline control. REACT is an active biological ingredient acquired from a percutaneous tissue acquisition from the patient’s kidney cortex. The specimen undergoes a GMP-compliant manufacturing process that harvests the selected renal cells composed of progenitors for renal repair, followed by image-guided locoregional reinjection into the patient’s renal cortex. Participants receive 2 doses at 6-month intervals. Primary outcomes are stable renal function and stable/improved quality of life. Additional exploratory endpoints include the impact of REACT on blood pressure, vitamin D levels, hemoglobin, hematocrit and kidney volume by MRI analysis. Results: Four men and 1 woman were enrolled and underwent 5 cell injections. Their characteristics were as follows: mean 52.8 years (SD 17.7 years), 1 Hispanic, 4 non-Hispanic, and 5 white. There were no renal tissue acquisition, cell injection, or cell product-related complications at baseline. Conclusion: REACT is demonstrating feasibility and patient safety in preliminary analysis. Autologous cell therapy treatment has the potential to stabilize or improve renal function in CAKUT-associated CKD to delay or avert dialysis. Patient enrollment and follow-up are underway.

AbstractDuchenne muscular dystrophy (DMD) is characterized by progressive degeneration of skeletal muscles. To date, there are no treatments available to slow or prevent the disease. Hence, it remains essential to identify molecular factors that promote muscle biogenesis since they could serve as therapeutic targets for treating DMD. While the muscle enriched microRNA, miR-133b, has been implicated in the biogenesis of muscle fibers, its role in DMD remains unknown. To assess the role of miR-133b in DMD-affected skeletal muscles, we genetically ablated miR-133b in the mdx mouse model of DMD. In the absence of miR-133b, the tibialis anterior muscle of juvenile and adult mdx mice is populated by small muscle fibers with centralized nuclei, exhibits increased fibrosis, and thickened interstitial space. Additional analysis revealed that loss of miR-133b exacerbates DMD-pathogenesis partly by altering the number of satellite cells and levels of protein-encoding genes, including previously identified miR-133b targets as well as genes involved in cell proliferation and fibrosis. Altogether, our data demonstrate that skeletal muscles utilize miR-133b to mitigate the deleterious effects of DMD.
