Gemcitabine Hydrochloride, Clofarabine, and Busulfan before Donor Stem Cell Transplant in Treating Patients with Refractory B-Cell or T-Cell Non-Hodgkin Lymphoma or Hodgkin Lymphoma

Status: complete

This phase I/II trial studies the side effects and best dose of gemcitabine hydrochloride, clofarabine, and busulfan before donor stem cell transplant and to see how well it works in treating patients with B-cell or T-cell non-Hodgkin lymphoma or Hodgkin lymphoma that does not respond to treatment. Giving chemotherapy before a donor bone marrow or peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem 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.

Inclusion Criteria

Patients with refractory B-cell or T-cell non-Hodgkin's lymphoma or Hodgkin's lymphoma who are eligible for allogeneic transplantation

Estimated serum creatinine clearance >= 50 ml/min (using the Cockcroft-Gault formula)
Serum creatinine =< 1.6 mg/dL
Serum bilirubin =< 2 x upper limit of normal
Serum glutamate pyruvate transaminase (SGPT) =< 2 x upper limit of normal
Able to sign informed consent

Exclusion Criteria

Active hepatitis B, either active carrier (hepatitis B virus surface antigen [HBsAg] +) or viremic (hepatitis B virus [HBV] deoxyribonucleic acid [DNA] >= 10,000 copies/mL, or >= 2,000 IU/mL)
Evidence of either cirrhosis or stage 3-4 liver fibrosis in patients with chronic hepatitis C or positive hepatitis C serology
Human immunodeficiency virus (HIV) infection
Active uncontrolled bacterial, viral or fungal infections
Exposure to other investigational drugs within 2 weeks before enrollment
Grade >= 3 non-hematologic toxicity from previous therapy that has not resolved to =< grade 1
Radiation therapy to head and neck (excluding eyes), and internal organs of chest, abdomen or pelvis in the month prior to enrollment
Prior whole brain irradiation
Prior autologous stem-cell transplant (SCT) in the prior 3 months

PRIMARY OBJECTIVES:

I. To define the maximum tolerated dose (MTD) of infusional gemcitabine (gemcitabine hydrochloride) combined with fixed doses of clofarabine and busulfan in patients with lymphoma receiving an allogeneic stem-cell transplant (alloSCT).

II. To estimate the day +100 success rate, defined as percentage of patients who are alive, engrafted and without grade 3-4 graft-versus (vs.)-host-disease (GVHD).

SECONDARY OBJECTIVES:

I. To estimate the day +100 success rate (defined as percentage of patients who are alive, engrafted and without grade 3-4 graft-vs.-host-disease [GVHD]).

II. To estimate the rate of event-free (EFS).

III. To estimate the rate of overall survival (OS).

IV. To estimate the response rate (RR) (defined as # of responses / # of patients with measurable tumors).

V. To estimate the complete response (CR) rate (defined as # of complete responses / # of patients with measurable tumors).

VI. To estimate the incidence of grade 2-4 and grade 3-4 acute GVHD.

VII. To estimate the incidence of limited and extensive chronic GVHD.

OUTLINE: This is a phase I, dose-escalation study of gemcitabine hydrochloride followed by a phase II study.

PREPARATIVE REGIMEN: Patients receive gemcitabine hydrochloride intravenously (IV) over 40-180 minutes on days -6 and -4, clofarabine IV over 1 hour on days -6 to -3, and busulfan IV over 3 hours on days -6 to -3. Patients with matched unrelated donors also receive antithymocyte globulin IV on days -3 to -1 and patients with cluster of differentiation (CD)20-positive disease also receive rituximab IV on days -14, -7, 1, and 8.

TRANSPLANT: Patients undergo allogeneic bone marrow (BMT) or peripheral blood stem cell transplant (PBSCT) on day 0.

GVHD PROPHYLAXIS: Patients receive tacrolimus IV continuously over 24 hours or orally (PO). Beginning on day 0, patients receive mycophenolate mofetil IV over 2 hours or PO thrice daily (TID).

After completion of study treatment, patients are followed up at 3, 6, and 12 months, and then every 6 months for 4 years.
