The primary goal of the open label study of Renadyl™ in stage 3 and 4 chronic kidney disease patients was to confirm the safety and tolerability of several doses of Renadyl™ (90, 180, 270 billion colony forming units). Secondary goals were to quantify quality of life improvement, to confirm efficacy in reducing commonly known uremic toxins, and to investigate the effects on several biomarkers of inflammation and oxidative stress. Participants underwent physical examinations and venous blood testing, and completed quality of life questionnaires. Data were analyzed with SAS V9.2. Of 31 subjects, 28 (90%) completed the study (2 lost to follow-up). The primary goal was met, as no significant adverse events were noted during the dose escalation phase. All patients tolerated the maximum dose (note: 1 subject reported nausea upon initial use). The escalation efficacy was shown in statistically significant changes of serum creatinine (months 2 to 6: -0.23 mg/dL, p<0.05), C-reactive protein (months 2 to 6: -0.28 mg/L, p<0.05), and hemoglobin (base to month 6: 0.35 mg/dL, p<0.01, months 1 to 6: 0.46 mg/dL, p<0.001, months 2 to 6: 0.58 mg/dL, p<0.0001). Trends, but not statistical significance, were noted in blood urea nitrogen (base to month 4: -3.56 mg/dL, p<0.09; months 1 to 4: -3.81 mg/dL, p<0.07). The secondary goal was also met, as QOL measure of physical functioning improved (base to month 6, p<0.05) and a strong trend in reduction of pain was observed (base to month 6, p<0.08).
