What was measured

CML Acquisition of a new cytogenetic abnormality and/or development of accelerated phase or blast crisis. Criteria for accelerated phase: unexplained fever \>38.3° C, new clonal cytogenetic abnormalities in addition to a single Ph-positive chromosome, BM blasts and promyelocytes \>20%. AML, ALL, CMML \>30% BM blasts w/ deteriorating performance status, or worsening of anemia, neutropenia, or thrombocytopenia. CLL Progressive disease: ≥1 of: physical exam/imaging studies (nodes, liver, and/or spleen) ≥50% increase or new, circulating lymphocytes by morphology and/or flow cytometry ≥50% increase, and lymph node biopsy w/ Richter's transformation. NHL \>25% increase in the sum of the products of the perpendicular diameters of marker lesions, or the appearance of new lesions. MM ≥100% increase of the serum myeloma protein from its lowest level, or reappearance of myeloma peaks that had disappeared w/ tx; or definite increase in the size/number of plasmacytomas or lytic bone lesions.

Analysis population: No subjects were enrolled onto Group 2D because the dose escalation was not triggered before the study closed to accrual.

Groups in this outcome

Group 1A (Pentostatin, DLI Dose Level 1)

Patients receive pentostatin IV over 20-30 minutes on day -2 and DLI (1x10\^7 CD3+ cells/kg) over 15-30 minutes on day 0. Treatment may repeat once beginning with an escalated or same CD3-dose at least 4 weeks if persistent donor T-cells are documented, no GvHD has developed, and the chimerism status worsens or, if chimerism status is unchanged after at least 8 weeks with two subsequent tests of chimerism 4 weeks apart. Pentostatin: Given IV Therapeutic Allogeneic Lymphocytes: Given IV

Group 1B (Pentostatin, DLI Dose Level 2)

Patients receive pentostatin IV over 20-30 minutes on day -2 and DLI (3x10\^7 CD3+ cells/kg) over 15-30 minutes on day 0. Treatment may repeat once beginning with an escalated or same CD3-dose at least 4 weeks if persistent donor T-cells are documented, no GvHD has developed, and the chimerism status worsens or, if chimerism status is unchanged after at least 8 weeks with two subsequent tests of chimerism 4 weeks apart. Pentostatin: Given IV Therapeutic Allogeneic Lymphocytes: Given IV

Group 2C (Pentostatin, DLI Dose Level 1, Add'l IS)

Patients receive treatment as in group 1A. Patients also receive cyclosporine PO BID on days -3 to 56 and mycophenolate mofetil PO QD on days 0 to 27. Treatment continues in the absence of GvHD. Pentostatin: Given IV Therapeutic Allogeneic Lymphocytes: Given IV

Group 2D (Pentostatin, DLI Dose Level 2, Add'l IS)

Patients receive treatment as in group 1B. Patients also receive cyclosporine PO BID on days -3 to 56 and mycophenolate mofetil PO QD on days 0 to 27. Treatment continues in the absence of GvHD. Pentostatin: Given IV Therapeutic Allogeneic Lymphocytes: Given IV
