Trial Outcomes & Findings for Study in Subjects With Light Chain (AL) Amyloidosis (NCT NCT03154047)

NCT ID: NCT03154047

Last Updated: 2019-03-26

Results Overview

AEs are defined as any unfavorable and unintended diagnosis, symptom, sign (including an abnormal laboratory finding), syndrome, or disease which either occurs during study, having been absent at baseline, or, if present at baseline, appears to worsen. Serious adverse events are any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization, cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgment of investigators represent significant hazards.
