open-label extension study of neod001 in subjects with light chain (al) amyloidosis

Conditions: AL Amyloidosis

Summary: the rationale for this study is to provide additional treatment with neod001 for subjects who complete study neod001-001, and to continue to evaluate long term safety and tolerability. all subjects in the current neod001 trials are being dosed at 24 mg/kg, which will be continued in this study.

the rationale for this study is to provide additional treatment with neod001 for subjects who complete study neod001-001, and to continue to evaluate long term safety and tolerability. all subjects in the current neod001 trials are being dosed at 24 mg/kg, which will be continued in this study. the primary objective of the study is to evaluate long-term safety and tolerability of neod001 and the secondary objectives are to assess the immunogenicity of neod001 and to incorporate serum neod001 concentrations in a population pharmacokinetic (pk) analysis.
