Coronavirus Induced Acute Kidney Injury: Prevention Using Urine

Status Terminated

Clinical Trial Summary

Our overarching goal is to improve the outcomes of critically ill COVID-19 patients with or at risk for development of acute kidney injury (AKI). The objective of this study is to determine the role of a protocol to manage urine alkalization using a simple medication that has been used for a very long time, is safe, and without significant side-effects. We aim to determine the feasibility and safety of a urine alkalinization protocol for the prevention of AKI in patients testing positive for COVID-19.

Clinical Trial Description

Emerging evidence suggests that acute kidney injury (AKI) secondary to COVID-19 (COV-AKI) might result from direct infection of renal tubule epithelial cells (RTEC). A variety of epithelial cells express the ACE2 receptor which contains the receptor-binding domain (RBD) used by SARS-CoV-1 and SARS-CoV-2 to enter the cells. While direct infection of RTEC has not yet been proven data from multiple laboratories show virus in the kidney. It is this direct viral involvement of the RTEC that this proposal seeks to address. One relatively simple approach would be to perturb the ability of the RBD to bind to its cellular (hACE2) receptor. Changes in pH may cause each amino acid residue, in the RBD, to assume a slightly different 'microscopic' conformation-dependent pKa value. Urine pH is normally 5.5- 6.5 (not too dissimilar to alveolar fluid-6.4-6.86) and can be easily and safely manipulated. In fact, urine alkalinization protocols have been used for decades to reduce renal toxicity from various compounds (especially chemotherapy) and are recommended by US and European toxicology societies. Here, the strategy will be deployed not for ion trapping but to inhibit the virus from infecting RTEC. Alkalinizing the urine using IV sodium-bicarbonate solution to pH of 7.5 or more can be easily and safely achieved. While severe AKI does not appear to be a major part of the SARS-CoV-2 syndrome for most patients, when severe AKI does occur, mortality is very high and preventing early AKI may reduce AKI severity as the disease progresses. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
