September 29, 2026 7:12 AM EDT

~ In 12 high-dose patients at 48 months, both cUHDRS and TFC continued to demonstrate meaningful slowing of disease progression and clear dose-dependent response; the primary endpoint of cUHDRS showed 44% slowing of disease progression (non-significant p=0.144) and TFC showed a 61% slowing of disease progression (nominal p=0.008) ~ 

~ Updated data reflecting all 15 high-dose patients showed substantial treatment effect on both cUHDRS and TFC at 36 months, the timepoint that is the regulatory anchor for the submitted BLA and the confirmatory study; the new analysis demonstrated 80% slowing of disease progression based on cUHDRS (nominal p=0.005) and 67% based on TFC (nominal p=0.011)...
