Official title

Multicenter, Prospective, Randomized, Placebo-Controlled, Double-blind Dose Escalating Study of Safety, Tolerability and Pharmacodynamics of Zirconium Silicate in Chronic Kidney Disease and Moderate Kidney Dysfunction With Mild Hyperkalemia

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

It is hypothesized that zirconium silicate is safe and well tolerated and more effective than placebo (alternative hypothesis) in lowering serum potassium levels in subjects with serum potassium between 5 - 6.0 mmol/l versus no difference between zirconium silicate and placebo (null hypothesis). It is hypothesized that zirconium silicate even up to the top dose of 10g three times a day is well tolerated.
