Early Allogeneic Hematopoietic Cell Transplantation in Treating Patients With Relapsed or Refractory High-Grade Myeloid Neoplasms

University of Washington30 enrolled

Overview

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.

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.

Factors That Distinguish Patients Who Received Early Transplant From Those Who Did Not - TREATMENT RELATED MORTALITY

Patients who receive early transplant will be compared to those that don't using the Wilcoxon rank sum test for the quantitative variable of treatment-related mortality (TRM). This outcome measure is intended to report a predicted TRM score assessed at the time of feasibility evaluation. The TRM score is used to measure "treatment-related mortality," or likelihood of death within 28 days of initiation of induction chemotherapy for patients with AML. The score is normalized from 0 to 100, so that a score of 0 demonstrates the patient has a very low likelihood of TRM and a score of 100 a very high likelihood of death. A calculation is used to predict TRM using age, performance status, if they have secondary AML, albumin, creatinine, platelet count, white blood cell count, and peripheral blood blast percentage. The higher the TRM score, the higher the risk of TRM. Calculator and table of relationship between TRM score and TRM probability found here: https://trmcalculator.fredhutch.org/.

Time frame: From time of subject's study enrollment to time of subject's feasibility success assessment (i.e. when subject received transplant within 60 days or when it was determined subject would not proceed with transplant on study)

Factors That Distinguish Patients Who Received Early Transplant From Those Who Did Not - GENDER

Patients who receive early transplant will be compared to those that don't using the Fisher's exact test for the categorical variables of gender.

Factors That Distinguish Patients Who Received Early Transplant From Those Who Did Not - AGE
