N/A | 阿尔茨海默症 维持 | - | 壓顧鹽膚獵簾壓鑰築艱(鏇選選簾膚鹽壓願觸鹹) = Data supports that transitioning to a weekly 360 mg SC AI dose of lecanemab after 18 months of initiation dose (10 mg/kg IV biweekly) maintains clinical and biomarker benefits comparable to continued biweekly IV dosing. Clinical and biomarker responses at 48 months with monthly IV maintenance dosing are similar to the responses with ongoing biweekly dosing whether patients are amyloid positive (>30 CL) or negative (<30 CL) at 18 months. Data shows the 500 mg SC AI has equivalent exposure as the initial treatment regimen of 10 mg/kg IV biweekly up to 18 months for amyloid removal, efficacy, and ARIA-E. 醖襯顧鑰膚製製糧衊窪 (窪廠糧獵範衊壓鹹顧選 ) 更多 | 积极 | 2025-07-30 | ||
