Allogeneic transplantation is used to treat many malignant and non-malignant diseases, though the potential toxicities of the procedure remain high. We and others have shown that a less toxic preparative regimen allows reliable allogeneic engraftment for allogeneic transplantation.
The primary purpose of this treatment trial is to follow subjects undergoing allogeneic transplantation for long term outcomes. The regimen used has been tested in our prior phase I / II trial which has completed accrual. The issues of engraftment and rate of graft versus host disease have been answered and our success has led to this regimen being a standard approach for less toxic allogeneic therapy.

Experimental: Campath Purged Non-myeloablative ASCT
Campath Purged Non-myeloablative Allo Stem Cell Transplant (ASCT) in lymphoma, myeloma, or marrow failure: leukemia or myelodysplasia; and solid tumors
Drug: Campath Purged Non-myeloablative ASCT
Preparative regimen: Begins on day -5 and consist of 4 days of daily fludarabine at 30 mg/m2/d infused over 30 minutes, cyclophosphamide 500 mg/m2/d infused over 1 hour, 5 days of Campath-1H at 20 mg/d in 250 ml of D5 normal saline or normal saline infused over 3 hours.
Subject Evaluation will occur 2-3 times per week by physical exam for toxicity through day 45.
Other Name: Allogeneic Stem Cell Transplant (ASCT)
- Toxicity [ Time Frame: 1 year ]Acute graft versus host disease (GVHD) was graded according to the consensus criteria and NCI common terminology criteria for adverse events (CTCAE) v2.0 or 3.0 was used for all other toxicities. Recognizing that acute GVHD pathology in the nonablative and donor lymphocyte infusion (DLI) setting may occur late, we tabulated skin, gut and liver toxicity consistent with acute GVHD (aGVHD) at anytime in the year following the infusion as aGVHD. Toxicities were formally recorded for all patients twice weekly for the first 100 days, at each follow up visit, and as needed intercurrently.
- Overall Survival (OS) [ Time Frame: Up to 12 years; participants were followed for the duration of the study, an average of 8 years ]Estimate overall survival rates in subjects treated with a non-myeloablative preparative regimen followed by matched related allogeneic stem cells for allogeneic transplantation.
- Response [ Time Frame: 1 year ]
Response Assessment included physical exam and evaluation of peripheral blood and bone marrow. There's no widely accepted criteria for response other than complete response (CR).
CR for malignant hematologic diseases is met if all the following are met for >/= 1 month:
- absence of pathologic lymphadenopathy by physical and radiographic exam
- absence of constitutional symptoms due to disease
- Polymorphonuclear leukocyte count > 1,500/uL; platelet count >50,000/uL; and hemoglobin >10.0 g/dL
- bone marrow aspirate/biopsy done after (a) through (c) have been met, >/= 30% cellularity and an absence of abnormal lymphoid nodules or cells by flow cytometry, cytogenetics, etc.
- molecular markers of disease must be negative by polymerase chain reaction, Fluorescence in situ hybridization, cytogenetics etc.
CR for solid tumors requires complete resolution of disease on physical exam and radiographs. CR for marrow failure is normal white cell, platelet and hematocrit values.
