Women of child bearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 7 days prior to beginning of treatment (drug). Post-menopausal women (surgical menopause or lack of menses ≥12 months) do not need to have a pregnancy test, please document status.
* Performance status ≤ 2 (or KPS 70)
Exclusion Criteria of Recipient (patient):
* Evidence of HIV infection.
* Any uncontrolled severe, concurrent illness which in the opinion of the treating physician would make this protocol treatment unreasonably hazardous for the patient.
* Oxygen dependent obstructive pulmonary disease.
* Failure to demonstrate adequate compliance with medical therapy and follow-up
* Significant medical or psychiatric illness that would impair the ability to participate in protocol therapy.
* Previous allogeneic stem cell transplant
* Patients who have had previous purine analog (fludarabine, pentostatin, 2-CDA) treatment or treatment with alemtuzumab within 1 year of entering the study
* Previous history of Veno-occlusive disease/Sinusoidal Obstruction Syndrome
* Active hepatitis B or C
* Patients with known active central nervous system leukemia
* Patients with prior treatment of Gemtuzumab ozogamicin
* Patients eligible for allogeneic stem cell transplant
Donor Eligibility Criteria \* donor eligibility must be documented and assessed by a separate participating physician other than the treating physician of the recipient.
* Donors agree to up to 3 donor leukocyte collections as documented by assessing physician (although it is not required that the same donor is used for all leukocyte infusions it is preferable, therefore agreement is important at screening). This must be documented in writing by treating physician.
* Typing is required at the following loci: HLA A, B, C, and DRB1.
* Patients with a HLA 0/6 to 3/6(using loci A, B, DR) donor match will be able to participate in this protocol.
* Donors must be a first or second degree relative.
* If the patient/recipient is CMV negative, only CMV negative donors are eligible. If the patient/recipient is CMV positive, CMV testing is not required for the donor.
* Although ABO blood type matching is not required given use of apheresis product preference will be made to ABO compatible donors
* Donors must be ≥18 years of age to donate.
* Donor with a history of malignancy other than non-melanoma skin cancers are eligible only if they had a history of a solid tumor malignancy more than five years prior to lymphocyte donation, and are considered to be in longstanding complete remission as documented by a physician. The donor must be healthy and have all testing criteria completed and meet all criteria for stem cell donation.
* The donor will also be assessed by physician who will document behavioral risk for exposure to infectious agents and diseases. Testing will include the following: Human transmissible spongiform encephalopathy, including Creutzfeldt-Jakob disease, communicable disease risks associated with xenotransplantation, Chlamydia trachomatis and for Neisseria gonorrhea, Treponema pallidum (syphilis).This will exclude the donor.
* The donor must be in good general health and not have significant cardiopulmonary, renal, endocrine, or hepatic disease as documented in writing by physician.
* B-HCG urine or serum negative if donor is of childbearing potential within 7 days of PBMC procurement. Not applicable for donors who are Post-menopausal (surgical menopause or lack of menses ≥12 months).
* Donors must have adequate venous access so leukapheresis can be performed via standard peripheral IV without the need for placement of a central venous catheter.
Donor Exclusion Criteria:
* Evidence of infection for HIV-1, HIV-2, syphilis, hepatitis B or C, HTLV 1 or 2, WNV, Chagas.
* Uncontrolled diabetes mellitus. If donor has controlled diabetes this must be documented by physician.
* Active or congestive heart failure syndrome from any cause per donor medical history. Approval for participation by Cardiologist required to be sent to BrUOG.
* Full cardiac workup by a Cardiologist is required for any history of congestive heart failure syndrome, conduction abnormalities or history of arrhythmia other than treated atrial fibrillation.
* Active angina pectoris. To be documented by physician
* Oxygen dependent pulmonary disease. To be documented by physician
* History of any lymphoid, myeloid or other non-solid malignancy. To be documented by physician
* Failure to receive full informed consent.
* Inadequate renal and/or hepatic function per medical history. To be documented by physician
* Known history of cirrhosis or active liver disease per medical history. To be documented by physician
* History of transplantation. To be documented by physician.
* A donor in whom plasma dilution sufficient to affect the results of communicable disease testing is suspected, unless: (A) You test a specimen taken from the donor before transfusion or infusion and up to 7 days before recovery of cells or tissue; or (B) You use an appropriate algorithm designed to evaluate volumes administered in the 48 hours before specimen collection, and the algorithm shows that plasma dilution sufficient to affect the results of communicable disease testing has not occurred.
* Clinical situations in which you must suspect plasma dilution sufficient to affect the results of communicable disease testing will exclude the donor. Such situations include, but are not limited to the following:(A) Blood loss is known or suspected in a donor over 12 years of age, and the donor has received a transfusion or infusion of any of the following, alone or in combination:
1. More than 2,000 milliliters (mL) of blood (e.g., whole blood, red blood cells) or colloids within 48 hours before death or specimen collection, whichever occurred earlier, or
2. More than 2,000 mL of crystalloids within 1 hour before death or specimen collection, whichever occurred earlier.
