First treatment approved for deadly stem cell transplant complication

Leading company through first commercial launch

For decades, patients who developed transplant-associated thrombotic microangiopathy (TA-TMA) after stem cell transplants faced a grim reality: a life-threatening complication with no approved treatment. Mortality rates for high-risk cases reached 80-90%. In December 2025, the FDA approved Yartemlea, the first therapy for this condition, marking Seattle-based Omeros Corporation's first drug approval after 31 years. The company launched commercially on January 2, 2026, announced pricing at $36,000 per vial on January 7, and by late January both adult and pediatric patients were receiving treatment at transplant centers nationwide.
