Sanofi has initiated a Phase 2a clinical trial evaluating three experimental drugs—Frexalimab, SAR442970, and Rilzabrutinib—for treating primary focal segmental glomerulosclerosis (FSGS) and minimal change disease (MCD) in patients aged 16 to 75 years.
The kidney disease study employs a randomized, double-blind, placebo-controlled design with quadruple masking to assess changes in proteinuria and remission rates of nephrotic syndrome.
Separately, Sanofi is conducting a Phase 2 dose-ranging study of SAR441566, an oral tablet, for moderate-to-severe ulcerative colitis to evaluate clinical remission rates.
Both studies utilize rigorous randomized, double-blind methodologies with placebo controls and could significantly impact Sanofi's competitive position in treating these challenging conditions.
