REduced-dose Steroid PrOtocol for Childhood Nephrotic SyndromE (RESPONSE): a Pilot Open-label Randomized, Controlled Trial
This is a pilot feasibility study for a proposed full-scale randomized controlled trial to evaluate the effectiveness and safety of a reduced-dose oral prednisone (steroids) regimen to treat childhood steroid-sensitive nephrotic syndrome relapses versus standard-dose prednisone (i.e., usual standard of care). This internal pilot study is a single-center, open-label, randomized controlled trial at The Hospital for Sick Children (Toronto, ON, Canada). The primary objective of this pilot study is to determine the feasibility, safety, and resources needed to conduct the future full-scale randomized controlled trial.
