Darbepoetin Alfa MDS Companion Protocol

Phase 3

Completed

Brief Summary: The primary objective of the study was to provide required access of investigational product (darbepoetin alfa) beyond the end of the active treatment period (EOATP) of the darbepoetin alfa MDS 20090160 (NCT01362140) study for patients who had continued demonstration of benefit from darbepoetin alfa treatment and to describe the safety of longer-term use in this patient population.

Detailed Description: This is a phase 3b, multi-centre, open-label, single-arm companion study to the MDS 20090160 study (NCT01362140) for the treatment of anaemic patients with MDS. Participants who completed the active-treatment period of the darbepoetin alfa MDS 20090160 study and met the eligibility criteria could be enrolled into this study to continue treatment of darbepoetin alfa for up to 73 weeks or until progression to acute myelogenous leukemia (AML), whichever occurs first.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Treatment-emergent Adverse Events	From first dose of darbepoetin alfa to 30 days after last dose; the maximum treatment duration was 73 weeks.	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.
