Scientific Trials Supporting Subcutaneous Maintenance Dosing Approval
- The BLA is based upon LEQEMBI subcutaneous (SC) sub-studies of the Phase 3 Clarity advertisement open-label extension (OLE) trial in people with early advertisement, which examined a series of subcutaneous dosages. Information reveals that transitioning to the weekly LEQEMBI IQLIK autoinjector after 18 months of the initiation dosage (10 mg/kg IV every 2 weeks) preserves scientific and biomarker advantages equivalent to ongoing IV dosing.
- The security of LEQEMBI IQLIK autoinjector was studied in over 600 clients at a variety of dosages as part of the Clarity Advertisement OLE.

- When benchmarked versus the anticipated decrease in the BioFINDER * 3 mate, lecanemab revealed a decrease of -2.17 points determined by CDR-SB at the four-year mark.
