NCT07765524

Brief Summary

This Phase I study is designed to evaluate the safety and efficacy of FKC289 in subjects with relapsed/refractory primary light chain (AL) amyloidosis.The primary objectives are to assess the safety of FKC289 and to establish the recommended Phase II dose (RP2D). And this Phase II study is designed to evaluate the efficacy of FKC289.The primary objectives are to assess proportion of subjects with hematologically best complete response (CR) within 6 months.
