About
This phase I/II trial studies whether stopping cyclosporine before mycophenolate mofetil is better at reducing the risk of life-threatening graft-versus-host disease (GVHD) than the previous approach where mycophenolate mofetil was stopped before cyclosporine. The other reason this study is being done because at the present time there are no curative therapies known outside of stem cell transplantation for these types of cancer. Because of age or underlying health status, patients may have a higher likelihood of experiencing harm from a conventional blood stem cell transplant. This study tests whether this new blood stem cell transplant method can be made safer by changing the order and length of time that immune suppressing drugs are given after transplant.
Full description
PRIMARY OBJECTIVES:
I. To determine whether the incidence of life-threatening GVHD can be reduced after unrelated donor peripheral blood mononuclear cell (PBMC) hematopoietic cell transplantation (HCT) using nonmyeloablative conditioning with earlier discontinuation of cyclosporine (CSP) and extended administration of mycophenolate mofetil (MMF) in patients with hematologic malignancies and metastatic renal cell carcinoma.
SECONDARY OBJECTIVES:
I. To compare the incidence of acute and chronic GVHD to protocols 1463 and 1641.
II. To compare the utilization of corticosteroids to protocols 1463 and 1641.
III. To compare survival to that achieved under protocol 1463 and 1641.
OUTLINE:
CONDITIONING: Patients receive fludarabine phosphate intravenously (IV) over 30 minutes on days -4 to -2, and undergo total-body irradiation (TBI) on day 0.
TRANSPLANTATION: Patients undergo allogeneic PBMC transplant on day 0.
IMMUNOSUPPRESSION: Patients receive cyclosporine orally (PO) twice daily (BID) on days -3 to 80 with taper to day 150 and mycophenolate mofetil PO or IV thrice daily (TID) on days 0-30, BID on days 31-150, and then taper to day 180. Treatment continues in the absence of unacceptable toxicity.
After completion of study treatment, patients are followed up periodically for 24 months and then yearly for 5 years.

Volunteers
Inclusion criteria
Ages > 50 years with hematologic malignancies treatable by unrelated HCT
Ages =< 50 years of age with hematologic diseases treatable by allogeneic HCT who through pre-existing medical conditions or prior therapy are considered to be at high risk for regimen related toxicity associated with a conventional transplant (> 40% risk of transplant-related mortality [TRM]) or those patients who refuse a conventional HCT; transplants must be approved for these inclusion criteria by both the participating institution's patient review committee such as the Patient Care Conference (PCC at the Fred Hutchinson Cancer Research Center [FHCRC]) and by the principal investigator at the collaborating center; patients =< 50 years of age who have received previous high-dose transplantation do not require patient review committee approval; all children < 12 years must be discussed with the FHCRC primary investigator (PI) prior to registration
Patients with metastatic renal cell carcinoma with the histologic subtypes of clear cell, papillary and medullary may be accepted regardless of age
The following diseases will be permitted although other diagnoses can be considered if approved by PCC or the participating institution's patient review committees and the principal investigator:
DONOR: FHCRC matching allowed will be grade 1.0 to 2.1: Unrelated donors who are prospectively:
DONOR: A positive anti-donor cytotoxic crossmatch is an absolute donor exclusion
DONOR: Patient and donor pairs homozygous at a mismatched allele in the graft rejection vector are considered a two-allele mismatch, i.e., the patient is A*0101 and the donor is A*0201, and this type of mismatch is not allowed
DONOR: G-PBMC only will be permitted as a HSC source on this protocol
Exclusion criteria
Patients with rapidly progressive intermediate or high grade NHL
Renal cell carcinoma patients
Central nervous system (CNS) involvement with disease refractory to intrathecal chemotherapy
Fertile men or women unwilling to use contraceptive techniques during and for 12 months following treatment
Females who are pregnant
Patients with non-hematological tumors except renal cell carcinoma
Fungal infections with radiological progression after receipt of amphotericin B or active triazole for greater than 1 month
Cardiac ejection fraction < 35%; ejection fraction is required if there is a history of anthracycline exposure or history of cardiac disease
Diffusing capacity of the lung for carbon monoxide (DLCO) < 40% and/or receiving supplementary continuous oxygen
The FHCRC PI of the study must approve of enrollment of all patients with pulmonary nodules
Patients with clinical or laboratory evidence of liver disease would be evaluated for the cause of liver disease, its clinical severity in terms of liver function, and the degree of portal hypertension; patients will be excluded if they are found to have fulminant liver failure, cirrhosis of the liver with evidence of portal hypertension, alcoholic hepatitis, esophageal varices, a history of bleeding esophageal varices, hepatic encephalopathy, uncorrectable hepatic synthetic dysfunction evinced by prolongation of the prothrombin time, ascites related to portal hypertension, bridging fibrosis, bacterial or fungal liver abscess, biliary obstruction, chronic viral hepatitis with total serum bilirubin > 3 mg/dL, and symptomatic biliary disease
Karnofsky scores < 60 (except renal cell carcinoma [RCC])
Patients with > grade II hypertension by Common Toxicity Criteria (CTC)
Human immunodeficiency virus (HIV) positive patients
The addition of cytotoxic agents for "cytoreduction" with the exception of hydroxyurea and imatinib mesylate will not be allowed within two weeks of the initiation of conditioning
DONOR: Marrow donors
DONOR: Donors who are HIV-positive and/or, medical conditions that would result in increased risk for G-CSF mobilization and harvest of G-PBMC
