Methods
study design
eAQUA (NCT01444456) was a large, Phase IV, multicenter,
international, prospective, observational study of patients
who were receiving systemic chemotherapy for solid tumors
and who were receiving DA or another ESA to treat symptomatic CIA. Although DA is the focus of this study, local
regulations in some countries do not permit observational
study participation by only patients receiving a specifi
agent in a drug class. Therefore, enrollment of patients who
were receiving an ESA other than DA was permitted in these
countries. Target recruitment was ∼1,300 patients across
approximately ten countries and the enrollment period was
∼12 months. Data collection was from enrollment up to 4
weeks after the last recorded dose of ESA or current chemotherapy regimen, the date of withdrawal, or a maximum of 13
weeks after enrollment (whichever occurred fist).
The study protocol was approved by the relevant Independent Ethics Committee and the study was conducted in
compliance with International Conference on Harmonization Good Clinical Practice guidelines and with the ethical
standards laid down in the 1964 Declaration of Helsinki. All
patients provided informed consent before data collection
commenced.
