The purpose of this study is to find out if treating Chronic Myelomonocytic Leukemia (CMML) with a study drug [ruxolitinib] can improve outcomes of patients with CMML. The first step of the study is to learn the dose of ruxolitinib that is tolerable (bearable). It has already been studied in a number of patients with different bone marrow diseases and is approved for the treatment of a disease called Myelofibrosis; however, it is not approved for treatment of CMML. It is given orally (by mouth). Most people tolerate it well but the tolerability has not been determined in patients with CMML. We will be testing different doses to determine how much of the medication people can tolerate (bear) before they develop side effects.
