Enhancement Of High-Dose Chemotherapy and Autologous SCT with the PARP Inhibitor Olaparib for Refractory Lymphoma.

Purpose: More active high-dose chemotherapy (HDC) regimens are needed for autologous stem-cell transplantation (ASCT) for refractory lymphomas. Seeking HDC enhancement with a poly(ADP-ribose) polymerase (PARP) inhibitor, we observed marked synergy between olaparib and vorinostat/gemcitabine/busulfan/melphalan (GemBuMel) against lymphoma cell lines, mediated by inhibition of DNA damage repair. Our preclinical work led us to clinically study olaparib/vorinostat/GemBuMel with ASCT.

Incidence of bacterial blood stream infections in patients with acute GVHD.

Bacterial bloodstream infections (BSI) can be a substantial contributor to complications of GVHD treatment. The aim of this study was to determine the risk for BSI from neutrophil engraftment through day 100 post transplant in patients with acute GVHD (AGVHD) based on organ involvement and severity. Patients (n = 4064) who underwent an allogeneic hematopoietic stem cell transplant (HCT) reported to the CIBMTR registry were analyzed.

High activity of the new myeloablative regimen of gemcitabine/clofarabine/busulfan for allogeneic transplant for aggressive lymphomas.

Refractory aggressive lymphomas can be treated with allo-SCT, pursuing a graft-vs-lymphoma effect. While reduced intensity conditioning is safe, tumors often progress rapidly, indicating the need for more active conditioning regimens. The preclinical synergy we saw between gemcitabine (Gem), clofarabine (Clo) and busulfan (Bu) against lymphoma cell lines led us to study Gem/Clo/Bu clinically.

Safety and long-term survival results of the addition of inotuzumab ozogamicin to the conditioning regimen of allogeneic stem cell transplantation: A single-center phase 1,2 trial.

Here we report on the first prospective study evaluating the safety and long-term survival when an escalating dose of inotuzumab ozogamicin (INO) (0.6, 1.2, or 1.

Myeloablative fractionated busulfan for allogeneic stem cell transplant in older patients or patients with comorbidities.

Traditional conditioning regimens for patients undergoing allogeneic hematopoietic cell transplantation (allo-HCT) provide suboptimal outcomes, especially for older patients and those with comorbidities. We hypothesized that a fractionated myeloablative busulfan dose delivered over an extended period would reduce nonrelapse mortality (NRM) while retaining antileukemic effects. Here, we performed a phase 2 trial for adults with hematological malignancies receiving matched related or unrelated allo-HCT.
