Introduction: Mitochondrial dysfunction plays an important role in the pathophysiology of kidney disease. Inhibitors of mitochondrial metabolism are being developed for the treatment of solid organ and hematologic malignancies. We describe the incidence and clinical features of acute kidney injury (AKI) in patients treated with the antimitochondrial drug CPI-613. Methods: We identified 33 patients with relapsed or refractory malignancy, previously enrolled in 3 open-label phase II studies, who received single-agent CPI-613 chemotherapy. AKI was defined by the Kidney Disease Improving Global Outcomes serum creatinine criteria. Participants were followed for a median (25th-75th percentile) of 120.0 (74.0-301.0) days. Risk factors for AKI were assessed by proportional hazards regression using univariate and multivariate analyses. Results: Participants had baseline mean (SD) age of 63.8 (11.6) years and serum creatinine 0.9 (0.3) mg/dl. AKI developed in 9 (27%) patients; chart review failed to identify a potential cause of AKI other than CPI-613 administration in 5 (15%) patients, of whom 1 had AKI stage 1, 1 had AKI stage 2, and 3 experienced AKI stage 3. Time from initiation of CPI-613 treatment to AKI was 51.0 (16.0-58.0) days. Age, per 5-year increase, was associated with higher risk of AKI ( adjusted hazard ratio 2.01, 95% confidence interval 1.06-3.79, P = 0.03). Follow-up serum creatinine was available in 4 participants 174.8 (139.6) days after the episode of AKI; 3 patients had complete recovery in kidney function and 1 had partial recovery. Conclusion: AKI is a possible complication during treatment with mitochondria-targeted chemotherapy.
