What is it about?

This study reanalyzed data from a large clinical trial to reveal the stages of polycystic kidney disease at which tolvaptan, a drug developed to treat the disease, might have the greatest effect.

Why is it important?

There is currently no treatment for polycystic kidney disease. The large clinical trial lumped all of the treated patients together; the results were positive and statistically significant, however, some critics the outcome is not sufficiently robust. This reanalysis found that patients with the worst kidney function had the greatest response to therapy.

Perspectives

I think this study validates the use of tolvaptan to treat polycystic kidney disease.
