Filter by:This Phase 1 clinical study is designed to examine the safety and feasibility of using anti-CD3/CD28 activated marrow infiltrating lymphocytes (MILs) as treatment of relapse after allogeneic hematopoietic cell transplantation (alloHCT) for patients with hematologic malignancies with bone marrow involvement of their relapsed disease. These MILs will be derived from the bone marrow of the relapsed patient who had previously received post-transplantation cyclophosphamide (PTCy) as graft-versus-host disease (GVHD) prophylaxis (PTCy-MILs). A bone marrow aspiration will be performed on the patient to collect ~200ml of marrow for ex vivo expansion. During this expansion process, T cells will be activated and expanded by co-stimulation with anti-CD3/anti-CD28 monoclonal antibodies covalently attached to super-paramagnetic microbeads. Patients will be treated with salvage therapy while this ex vivo expansion is ongoing. After the simultaneous salvage therapy and ex vivo expansion, the activated PTCy-MILs will be reinfused. Patients will be monitored with the primary objective being the feasibility of expanding to targeted dose levels activated PTCy-MILs that do not cause grade III-IV acute GVHD within the first 90 days after PTCy-MIL infusion.
Viral infections and reactivation during pediatric allogeneic hematopoietic stem cell transplantation (HSCT) are a common occurrence and significantly contribute to post-transplant morbidity and mortality. The risk is high due to prolonged periods of immune deficiency while awaiting immune reconstitution post-transplant. Current strategies to reduce complications from viral infections include prophylactic treatment, close monitoring for viral infections and prompt treatment at the first sign of symptoms or increasing viral load. However, the most definitive treatment for viral infections remains the host's cellular defenses. Improved understanding of the immune systems response to viral infections may lead to better treatment strategies. This study is being done to explore the relationships between T-cells and NK cells (infection fighting cells) and viral infections or reactivations in young allogeneic stem cell transplant patients. The investigators will be looking at how these cells react and function in young patients receiving allogeneic stem cell transplantation, as well as in healthy stem cell donors.
The investigators hypothesize that adding carfilzomib to standard conditioning regimen for allo-HCT for advanced or high-risk hematologic malignancies will decrease post-transplant relapse and treatment-related mortality by decreasing severe GVHD, leading to overall improvement in transplant outcomes.
No prospective randomized trials have evaluated the most efficacious dose of cyclophosphamide to mobilize autologous stem cells. We previously demonstrated that the time to collection of autologous hematopoietic stem cells is 10-12 days following the one dose of cyclophosphamide and daily G-CSF (granulocyte-colony stimulating factor).9 This prospective randomized trial is designed to determine if a lower dose of cyclophosphamide (1.5 gm/m2) will be as efficacious as the intermediate dose (3 gm/m2), based on cell number collected, number of apheresis required and resource utilization.
This phase I trial studies the side effects and best dose of targeted marrow irradiation when given with fludarabine phosphate and busulfan before donor progenitor cell transplant in treating patients with hematologic malignancies. Targeted marrow irradiation is a type of specialized radiation therapy that delivers a high dose of radiation directly to the cancer cells, which may kill more cancer cells and cause less damage to normal cells. Giving targeted marrow irradiation and chemotherapy drugs, such as fludarabine phosphate and busulfan, before a donor progenitor cell transplant may help stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's progenitor cells. When the healthy progenitor cells from a donor are infused into the patient they may help the patient's bone marrow make progenitor cells, red blood cells, white blood cells, and platelets.
This is a single institution, phase I dose escalation study of weekly romiplostim post umbilical cord blood transplantation in patients who fail to achieve platelet engraftment by day +30. Engraftment is defined as a platelet count ≥ 20 x 109/L on 3 consecutive measurements without transfusion for 7 days. Romiplostim is administered at the assigned dose as 6 weekly injections beginning by day +42 post transplant. Up to 4 dose levels (4, 6, 8, and 10 mcg/kg/dose) will be evaluated with the maximum tolerated dose (MTD) of romiplostim determined by using the Continual Reassessment Method (CRM). The goal of this CRM will be to identify 1 of the 4 dose levels which corresponds to the desired maximum toxicity rate of 20% or less.
The purpose of this study is to compare the safety and efficacy of carfilzomib, including measuring the amount of the study drug in the blood at certain times following dosing. This study is being done in people with varying degrees of liver function to see if they respond differently to the study drug.
We are interested in studying whether and how medical problems other than primary cancer before hematopoietic cell transplantation would impact the profiles of quality of life and toxicities post-transplantation for patients with blood cancers. We want to see if by assessing comorbidities (such as diabetes) early on, we can identify those patients who will have more toxicities or limitations in their quality of life after transplant. The generated information could set the stage for future intervention studies aiming to improve quality of life for patients with blood cancers after transplantation.
This is a phase 1, 2-part, pharmacokinetic study in patients with advanced solid tumors or hematologic malignancies and varying degrees of liver dysfunction (normal function, moderate or severe hepatic impairment) as defined by the National Cancer Institute (NCI) Organ Dysfunction Working Group.
The purpose of this study is to determine the pharmacokinetic and safety profiles of omacetaxine and its metabolites in patients with relapsed and/or refractory hematologic malignancies or advanced solid tumors following subcutaneous (sc) administration.
