Visit Criteria

If you qualify and decide to participate, your study participation will last for about 14.5 months. You will be randomly assigned to receive either the study drug or placebo (which has no active ingredients) as an infusion every 2 weeks. About 1 out of 3 patients will receive placebo in the first part of the study, but everyone will have the option to receive the study medication later in the study.

You will be required to report to CHOP about every 2 weeks for receiving the study drug, blood tests and physical exams. You may benefit if the study drug lessens the symptoms associated with your anemia.
