This is an interventional treatment trial for Bone Marrow Transplant Failure Read More

Inclusion Criteria:5.1.1 Steroid dependent/refractory cGVHD defined as:

1. Dependent disease - Persistent cGVHD manifestations requiring a glucocorticoid dose >= prednisone 0.25 mg/kg/day (0.5 mg/kg po qod) for at least 12 weeks.
2. Refractory disease - Progressive cGVHD manifestations despite treatment with a glucocorticoid dose >= prednisone 0.5 mg/kg/day (1 mg/kg po qod) for at least 4 weeks.

8. Patients must have the following laboratory values within normal limits at the local institution lab or corrected to within normal limits with supplements prior to the first dose of study medication:

Potassium Magnesium Phosphorus Calcium

5.1.10 Oxygen saturation during exertion maintained at >= 88% on room air.

5.1.11 Ability to understand and willingness to sign a written informed consent form.

5.1.12 Females with reproductive potential must have a negative pregnancy test <= 7 days before starting nilotinib. Reproductive potential will be defined as having at least 1 menstrual period in the past 12 months. Male and female subjects with reproductive potential agree to the use of barrier contraception during their treatment and for up to 3 months after the last dose.

5.1.13 Careful rationalization of concomitant medications with the intent to discontinue or change to alternative medications when any concomitant medications are identified that have the potential to prolong the QTcB interval or are associated with an increased risk of torsades de pointes. (Appendix B)

5.1.14 . Careful rationalization of concomitant medications with the intent to discontinue or change to alternative medications if any concomitant medications are identified to be strong CYP3A4 inhibitors. (Appendix C)

5.1.15 Myeloablative or non-myeloablative allogeneic hematopoietic cell transplant.

Exclusion Criteria:5.2.1 Currently receiving or has received within 28 days of starting study drug nilotinib or any other tyrosine kinase inhibitor.

5.2.2 Received any anti-T or anti-B cell monoclonal antibody <= 28 days prior to the anticipated start of study drug.

5.2.3 Currently receiving > two immunosuppressants other than glucocorticoids.

5.2.4 Currently receiving a calcineurin inhibitor and sirolimus

5.2.5 Received any investigational agents <= 28 days before starting nilotinib.

5.2.6 Impaired cardiac function including any one of the following:

1. Clinically significant resting brachycardia (<50 beats per minute).
2. QTc > 450 msec on baseline ECG. If QTc >450 msec and electrolytes are not within normal ranges, electrolytes should be corrected and then the patient re-screened for QTc.
3. Myocardial infarction within 12 months prior to starting study.
4. Other clinically significant uncontrolled heart disease (e.g. unstable angina, congestive heart failure or uncontrolled hypertension).
5. History of or presence of clinically significant ventricular or atrial tachyarrhythmias. (including congenital long QT syndrome or a known family history of congenital long QT syndrome)

5.2.7 Allogeneic cell infusion within 100 days

5.2.8 Uncontrolled infections not responsive to antibiotics, antiviral medicines, or antifungal medicines.

5.2.9 Progressive malignant disease including post transplant lymphoproliferative disease.

5.2.10 Any secondary malignancy except basal and squamous cell carcinoma of the skin within the past five years.

5.2.11 Nilotinib intolerance or hypersensitivity. 5.2.12 Impaired gastrointestinal (GI) function or GI disease that may significantly alter the absorption of study drug (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, small bowel resection or gastric bypass surgery).

5.2.13 Acute or chronic pancreatic disease 5.2.14 Major surgery within 4 weeks prior to Day 1 of the study or who have not recovered from prior surgery.
