Brief summary
This clinical trial studies how well early stem cell transplantation works in treating patients with high-grade myeloid neoplasms that has come back after a period of improvement or does not respond to treatment. Drugs used in chemotherapy, such as filgrastim, cladribine, cytarabine and mitoxantrone hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before a donor peripheral blood cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells. Early stem cell transplantation may result in more successful treatment for patients with high-grade myeloid neoplasms.
Detailed description
OUTLINE: RE-INDUCTION CHEMOTHERAPY: Patients receive filgrastim subcutaneously (SC) on days 0-5, mitoxantrone hydrochloride intravenously (IV) over 60 minutes on days 1-3, cladribine IV over 2 hours on days 1-5, and cytarabine IV over 2 hours on days 1-5. CONDITIONING REGIMEN: Beginning 14-60 days after re-induction chemotherapy, patients receive fludarabine phosphate IV over 30 minutes on days -6 to -2, melphalan IV on days -3 to -2, cyclosporine orally (PO) twice daily (BID) starting on day -3. Sirolimus PO BID starting on day -3 will be given to patients who have matched unrelated donors or mismatched unrelated donors. Patients \>55 years or with significant co-morbidities will only receive melphalan IV on day -2 and will also receive total body irradiation (TBI) on day -1 or day 0. EARLY TRANSPLANT: Patients undergo allogeneic HCT after conditioning regimen on day 0. GVHD PROPHYLAXIS: Patients with matched donors will receive mycophenolate mofetil PO three times daily (TID) on days 0-30, then twice a day (BID) until day 40; and cyclosporine PO BID on days -3 to 96, with a taper until day 150. Patients with matched unrelated donors also receive sirolimus PO BID on days -3 to 150, with a taper until day 180. Patients with mismatched unrelated donors will receive mycophenolate mofetil PO TID on days 0-30, then BID until day 100, with a taper until day 150; cyclosporine PO BID on days -3 to 150, then taper until day 180; and sirolimus BID PO days -3 to 180, then a taper until day 365. After completion of study treatment, patients are followed up periodically.
