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. 齋餘窪壓艱顧鹽鹹淵鬱 (顧遞築獵構簾艱艱齋網 ) 更多 | 积极 | 2025-07-30 | ||
