Summary Aims We assessed the potential efficacy and safety of propagermanium (PG), an organic compound that inhibits the C–C chemokine receptor type 2, administration in patients with type 2 diabetes and nephropathy. Furthermore, we assessed the feasibility of future studies. Materials and methods We recruited patients from nine medical institutions in Japan for this randomized, open‐label, parallel two‐arm pilot trial. Inclusion criteria were diagnosis of type 2 diabetes, age 30‐75 years, dipstick proteinuria of ≥1+ or urinary albumin‐to‐creatinine ratio (UACR) of ≥30 mg/g and estimated glomerular filtration rate of ≥30 mL/min/1.73 m 2 . Patients were randomly assigned (1:2) using a minimization algorithm to either continuing usual care or concomitant administration of 30 mg PG per day for 12 months. The primary outcome was the change in UACR from baseline to 12 months. We also collected safety information for all patients who received at least one dose of PG. Results We enrolled 29 patients, 10 were assigned to continue usual care and 19 to receive PG. Changes in UACR by PG in addition to the usual care were 25.0% (95% CI −20.4%, 96.5%, P  = .33). No severe adverse events or renal events were observed during the study. Conclusion Although the treatment with PG was generally well tolerated, the dosage of 30 mg/d for 12 months did not reduce albuminuria when used in addition to usual care in patients with type 2 diabetes and nephropathy. Efficacy of PG should be verified in future definitive trials.
