Ongoing Clinical Trials in AKI

AKI is an important public health issue. AKI is a common hospital complication associated with increased in-hospital and long-term mortality, extensive morbidity (including prolonged hospital length of stay), and an estimated annual cost of at least $10 billion in the United States. At present, no specific therapy has been developed to prevent AKI, hasten recovery of kidney function, or abrogate the deleterious systemic effects of AKI. However, recent progress includes establishing a consensus definition of AKI and discovery of novel biomarkers that may allow early detection of AKI. Furthermore, significant insights into the pathophysiology of AKI and its deleterious systemic effects have been gleaned from animal studies. Urgently needed are large, definitive randomized clinical trials testing interventions to prevent and/or treat AKI. This review summarizes and analyzes current ongoing clinical trials registered with clinicaltrials.gov that address prevention or management of AKI. The purpose of this review is to provide a resource for people interested in potential prophylactic and therapeutic approaches to patient care and investigators hoping to plan and execute the next round of randomized clinical trials. Finally, this review discusses research needs that are not addressed by the current clinical trials portfolio and suggests key areas for future research in AKI.
