Active clinical trials for "Hematologic Neoplasms"

The purpose of this study is to evaluate whether C-myb Antisense (AS) Oligonucleotides (ODNs)is a possible treatment modality for advanced hematologic malignancies.

Prospective randomized study of allogeneic minitransplantation from HLA-identical family or unrelated donors comparing unmanipulated or CD8-depleted PBSC. The conditioning regimen will be 2 Gy TBI alone (related donor with low-risk of transplant rejection) or 2 Gy TBI and 3 x 30 mg/m2 fludarabine (unrelated donor or high risk of transplant rejection). Patients will receive a short but intensive immunosuppressive treatment (cyclosporine and mycophenolate mofetil) to ensure both graft-versus-host and host-versus-graft tolerance. The rationale for using PBSC instead of marrow transplant is to avoid general anesthesia of the donor and to minimize the risk of rejection. The rationale for CD8+ depletion is to diminish the risk of GVHD after PBSC transplantation or DLI.

The purpose of this study is to evaluate a multi-dose regimen of SGN-30, a novel chimeric monoclonal antibody (mAb), in patients with refractory or recurrent CD30+ hematologic malignancies. This is a single-arm, open-label phase I/II study designed to define the toxicity profile, pharmacokinetic (PK) profile, and anti-tumor activity of a multi-dose regimen of SGN-30 in patients with refractory or recurrent CD30+ hematologic malignancies. The phase I study will be a modified dose escalation of SGN-30. Based on preclinical pharmacology and toxicokinetics (TK) and the first use in human single-dose phase I study, SGN-30 will be administered on a weekly schedule. An initial dose of 2 mg/kg will escalate until the maximum tolerated dose (MTD) has been reached or until a weekly dose of 12 mg/kg is achieved.

This proposal aims to characterize biochemical and physiologic factors that contribute to changes in patient fitness and body composition during hematopoietic stem cell transplantation (HCT) for hematologic malignancies. The study group will consist of 60 patients with hematologic malignancies treated with HCT. Measurements of patient fitness, body composition, and inflammatory milieu will be performed at visits before HCT, and 30 days (+/- 10 days) after HCT. For patients that continue to receive care at the Seattle VA, additional visits (not exceeding 6 total) may be requested periodically for up to 2 years after HCT.

The goal of this observational study is to compare the immune function and infection mechanism of patients with hematologic tumors and those people without underlying diseases after infection with SARS-CoV-2. Clinical characteristics, treatment options and responses will be collected. Peripheral blood will be collected from patients with hematologic tumors infected with SARS-CoV-2 and those people without underlying diseases infected with SARS-CoV-2.

This phase II trial studies how well total-body irradiation, donor lymphocyte infusion, and cyclophosphamide before donor stem cell transplant works in treating patients with high-risk hematologic malignancies. Giving total-body irradiation, donor lymphocyte infusion, and chemotherapy before a donor stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Removing the T cells from the donor cells before transplant and giving tacrolimus and mycophenolate mofetil may stop this from happening.

The study investigates the time to engraftment of a mesenchymal expanded cord blood unit in patients with hematologic malignancies undergoing transplantation with myeloablative conditioning.

To reduce the number of donors treated with IV AMD3100 who require a second collection to obtain the minimum cells necessary for allogeneic stem cell transplant.

The purpose of this study is to study the feasibility and Toxicity of allogeneic haploidentical hematopoietic cell transplantation with CD3/CD19 depleted stem cells and a dose reduced conditioning.

The administration of high-dose chemotherapy followed by the infusion of blood or bone marrow stem cells (stem cell transplantation) from a matched donor has become standard treatment for patients with high-risk or relapsed hematological cancers. Currently, donors are found for approximately 80% of people who require such treatment, although the chance of finding a donor is much lower in some ethnic communities. In the current study the investigators will offer patients requiring transplantation, but for whom well matched donors cannot be identified either from within the family or on the donor registry, a transplant from a half-matched (haploidentical) family member. A myeloablative conditioning regimen and un-manipulated peripheral blood stem cells will be used. Post-transplant cyclophosphamide, tacrolimus and mycophenolate mofetil will be used to prevent graft versus host disease (GVHD). The primary outcome measure will be 6 month survival free from graft failure, relapse and grade 3-4 acute GVHD. Other outcomes of interest will include the frequency of Cytomegalovirus (CMV) or Epstein-Barr Virus (EBV) requiring treatment, overall survival and progression-free survival.
