What this trial studies

This clinical trial evaluates the effects of Camostat Mesylate, a serine protease inhibitor, on patients with chronic kidney disease (CKD) and proteinuria. The study is designed as a non-randomized, open-label pharmacodynamic trial, including both CKD patients and healthy controls to assess the drug's impact on kidney function. Participants will follow a standardized sodium diet and receive Camostat Mesylate for four days while their kidney function and protein levels are monitored. The goal is to determine if this treatment can reduce kidney injury and improve clinical outcomes in CKD patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with chronic kidney disease and significant proteinuria.

Not a fit: Patients currently undergoing treatment with certain diuretics or those with ongoing cancer treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could slow the progression of chronic kidney disease and reduce associated cardiovascular risks.

How similar studies have performed: While this approach is novel in the context of CKD, similar studies using serine protease inhibitors have shown promise in other conditions.
