A Pilot Study of Anselamimab in Patients With AL Amyloidoma and Measurable Tissue Involvement

2026年8月19日 更新者:Stanford University

A Pilot Study of CAEL-101/Anselamimab in Patients With AL Amyloidoma and Measurable Tissue Involvement

This is an exploratory study to assess the binding of CAEL-101/anselamimab to amyloid in vivo, recruitment of inflammatory cells and reduction of the amyloid mass.

武器和干预

参与者组/臂
干预/治疗
实验性的:Anselamimab
Participants will receive anselamimab (CAEL-101) 1000 mg/m² by IV infusion weekly for 4 infusions, then every 2 weeks thereafter for up to 48 weeks. Premedication for infusion reaction prophylaxis may be administered according to institutional standards.

Patients will receive anselamimab administered by intravenous infusion. The dose will be 1000 mg/m² based on body surface area (BSA) calculated from height and weight obtained during screening. BSA will not be recalculated unless body weight changes by ≥20% from screening.

Study drug will be administered over approximately 2 hours. Participants will receive infusions every 7 (±1) days for the first 4 infusions, followed by every 14 (±2) days thereafter for a total treatment duration of 48 weeks. The maximum single dose is 2700 mg.

Participants will be monitored for infusion-related reactions and overall tolerability for approximately 90 minutes following completion of the first 4 infusions, or longer at the investigator's discretion.

Premedication with diphenhydramine (25-50 mg PO/IV), acetaminophen/paracetamol (325-650 mg PO/IV), and/or similar agents may be administered per institutional standards to reduce the risk of infusion-related reactions.
