The immune reactivity of allogeneic lymphocytes plays a major role in the control of leukemia after bone marrow transplantation. In patients with recurrent leukemia after marrow transplantation, chimerism and tolerance provide ideal conditions for adoptive immunotherapy with donor lymphocytes. We studied the effect of donor lymphocyte transfusions on acute(More)
Between May 1989 and February 1994, we performed 48 volunteer unrelated donor BMTs for first chronic phase chronic myeloid leukemia using in vivo T cell depletion for acute graft-versus-host disease (aGvHD) prophylaxis. In 40 cases, adequate material was available to measure the frequency of antirecipient MHC cytotoxic T lymphocyte precursor (CTLp) cells in(More)
Bortezomib (V) was combined with thalidomide (T) and dexamethasone (D) in a phase I/II trial to determine dose-limiting toxicities (DLT's) and clinical activity of the VTD regimen in 85 patients with advanced and refractory myeloma. The starting dose of V was 1.0 mg/m(2) (days 1, 4, 8, 11, every 21 day) with T added from cycle 2 at 50 mg/day, with 50 mg(More)
We have assessed the molecular response of 30 consecutive patients with chronic myeloid leukaemia (CML) treated for relapse after allogeneic bone marrow transplantation (BMT) by donor leucocyte transfusions (DLT). Response was evaluated by qualitative nested and quantitative competitive RT-PCR for BCR-ABL mRNA at various time intervals before and after DLT.(More)
We designed a new semi-quantitative competitor-based PCR assay to assess the amount of p190 BCR-ABL mRNA in patients with Ph-positive ALL. Transcript numbers were compared in 29 paired specimens of blood and marrow collected contemporaneously from 18 patients at differing stages of disease. In general, the numbers of BCR-ABL transcripts detected in marrow(More)
Melphalan-based autologous stem cell transplant (Mel-ASCT) is a standard therapy for multiple myeloma, but is associated with severe oral mucositis (OM). To identify predictors for severe OM, we studied 381 consecutive newly diagnosed myeloma patients who received Mel-ASCT. Melphalan was given at 200 mg/m2 body surface area (BSA), reduced to 140 mg/m2 for(More)
Refractory acute lymphoblastic leukemia (ALL) is often incurable, and relapse rates following allogeneic bone marrow transplantation (BMT) remain high. We have reported that patients who develop increased numbers of gammadelta(+) T cells soon after BMT are significantly less likely to relapse. We now show in seven donor/recipient pairs that donor-derived(More)
Allogeneic transplantation is successful in a minority of patients with primary refractory acute leukemia (PRAL). An HLA-matched sibling donor (MSD) is available only in 30-40% of the patients, whereas a partially mismatched related donor (PMRD) is available for most. We compared the outcome of 24 MSD (median age 24 years) and 19 PMRD (median age 34 years;(More)
Carfilzomib is a novel, highly selective, tetrapeptide epoxyketone proteasome inhibitor that irreversibly binds to the N-terminal threonine-containing active sites of the 20S proteasome, which is the proteolytic core particle within the 26S proteasome, as compared with bortezomib, which reversibly inhibits the 20S proteasome. 1 In vitro, carfilzomib has(More)
Donor lymphocyte responses to minor histocompatibility antigen (mHA) differences are involved in allo-responses between HLA matched pairs causing GVHD and graft-versus-leukaemia (GVL). Since some mHA are tissue-restricted, GVHD and GVL responses may be separable. We studied donor lymphocyte responses to patients with CML in a series of 10 HLA-matched(More)
