Calliditas Announces Primary Endpoint Successfully Met in Phase 3 NefIgArd Trial Evaluating Nefecon[®] in IgA Nephropathy
Calliditas Therapeutics AB (Nasdaq: CALT, Nasdaq Stockholm: CALTX) (“Calliditas”) today announced positive topline results from the global, randomized, double-blind, placebo-controlled Phase 3 clinical trial NefIgArd, which investigated the effect of Nefecon (TARPEYO®/Kinpeygo® (budesonide) delayed release capsules) versus placebo in patients with primary IgA nephropathy (IgAN).
- The trial met its primary endpoint with Nefecon demonstrating a highly statistically significant benefit over placebo (p value < 0.0001) in estimated glomerular filtration rate (eGFR) over the two-year period of 9-months of treatment with Nefecon or placebo and 15-months of follow-up off drug.
- Supportive 2-year total slope analyses were statistically significant and clinically meaningful reflecting a sustained treatment benefit.
- The eGFR benefit was observed across the entire study population, irrespective of urine protein-to-creatinine ratio (UPCR) baseline, which the company believes supports a regulatory filing for full approval in the study population.
- UPCR reductions observed were durable, reflecting a long lasting treatment effect during the 15-month follow-up period off treatment.
