Trial Outcomes & Findings for Darbepoetin Alfa MDS Companion Protocol (NCT NCT02175277)

NCT ID: NCT02175277

Last Updated: 2018-11-14

Results Overview

Adverse events (AEs) were graded for severity according to the Common Terminology Criteria for Adverse Events (CTCAE), version 4.0, where Grade 1 indicates a mild AE, Grade 2 indicates a moderate AE, Grade 3 indicates severe or medically significant but not immediately life-threatening and Grade 4 indicates life-threatening consequences; urgent intervention indicated. A serious adverse event was defined as an adverse event that met at least one of the following serious criteria: * fatal * life threatening * required in-patient hospitalization or prolongation of existing hospitalization * resulted in persistent or significant disability/incapacity * congenital anomaly/birth defect * other medically important serious event The investigator assessed whether each adverse events was related to darbepoetin alfa.
