Summary:

      This phase II trial studies how well deferasirox works in treating patients with very low,
      low, or intermediate-risk anemia or myelodysplastic syndrome that depends on red blood cell
      transfusions. Deferasirox may treat too much iron in the blood caused by blood transfusions.

                       without hysterectomy) or tubal ligation at least six weeks before taking
                       study treatment; in case of oophorectomy alone, only when the reproductive
                       status of the woman has been confirmed by follow up hormone level assessment

                    -  Male sterilization (at least 6 months prior to screening); for female
                       subjects on the study, the vasectomized male partner should be the sole
                       partner for that subject

               -  Women are considered post-menopausal and not of child bearing potential if they
                  have had 12 months of natural (spontaneous) amenorrhea with an appropriate
                  clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have
                  had surgical bilateral oophorectomy (with or without hysterectomy) or tubal
                  ligation at least six weeks ago; in the case of oophorectomy alone, only when the
                  reproductive status of the woman has been confirmed by follow up hormone level
                  assessment is she considered not of child bearing potential; sexually active

                  after stopping study medication and should not father a child in this period; a
                  condom is required to be used also by vasectomized men in order to prevent
                  delivery of the drug via seminal fluid
