• Patients with chronic GVHD that involves 3 or more organs or with a score of 2 or greater in any single organ based on NIH cGVHD grading

• Except for steroid refractory or intolerant cases, participants must be receiving baseline systemic glucocorticoid therapy for cGVHD at study entry. The dose of steroids must be stable for 14 days prior to starting study drug.
• At the time of trial enrollment, participants may be receiving one or two other immunosuppressive therapies in addition to glucocorticoids.

• Relapsed disease or development of other malignancies
• Laboratory parameters:

ANC <1 x 10^9/L Platelets < 50 x 10^9/L Bilirubin >1.5 upper limit of normal (ULN) when it is clearly not related to GVHD. EF <45% DLCO <45% Creatinine clearance <30 Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) > 5 × ULN

• Platelet count of <50 within 5 days before enrollment.
• Absolute neutrophil count of <1000 within 5 days before enrollment.
• Patient has > Grade 2 peripheral neuropathy
• Patient had myocardial infarction within 6 months prior to enrollment or has New York Heart Association (NYHA) Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities.
