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.

Background: Mitochondrial dysfunction is increasingly recognized as an important feature of multiple sclerosis (MS) pathology and may be relevant for clinical disease progression. However, it is unknown whether mitochondrial DNA (mtDNA) levels in the cerebrospinal fluid (CSF) associate with disease progression and therapeutic response. Objectives: To evaluate whether CSF concentrations of mtDNA in MS patients can serve as a marker of ongoing neuropathology and may be helpful to differentiate between MS disease subtypes. To explore the effect of disease-modifying therapies on mtDNA levels in the CSF. Methods: CSF mtDNA was measured using a digital polymerase chain reaction (PCR) CSF mtDNA in two independent MS cohorts. The cohorts included 92 relapsing-remitting multiple sclerosis (RRMS) patients, 40 progressive multiple sclerosis (PMS) patients (27 secondary progressive and 13 primary progressive), 50 various neurologic disease controls, and 5 healthy controls. Results: Patients with PMS showed a significant increase in CSF mtDNA compared to non-inflammatory neurologic disease controls. Patients with higher T2 lesion volumes and lower normalized brain volumes showed increased concentration of mtDNA. Patients treated with fingolimod had significantly lower mtDNA copy levels at follow-up compared to baseline. Conclusion: Our results showed a non-specific elevation of concentration of mtDNA in PMS patients. mtDNA concentrations respond to fingolimod and may be used to monitor biological effect of this treatment.
