Rule Changes

Leading company through FDA review process

No FDA-approved treatment for focal segmental glomerulosclerosis (FSGS) has ever existed. For the 40,000 Americans with this rare kidney disease—which drives half of patients to kidney failure within a decade—the only options have been off-label immunosuppressants with mixed results. On January 13, 2026, that was supposed to change. Instead, the FDA extended its review of sparsentan by three months, requesting more data on clinical benefit. The announcement triggered a 33% intraday stock plunge and sparked multiple shareholder investigations into potential securities law violations. Two weeks later, CEO Eric Dube sold $1.56 million in company stock, a transaction drawing scrutiny given its timing.
