Active clinical trials for "Hematologic Neoplasms"

Patients with blood cancers and those who received a bone marrow transplant frequently have low circulating white blood cell countS. Fever in patients with low white blood cell count requires early appropriate antibiotic treatment to prevent complications including death. Bacteria have increasingly become more resistant to existing antibiotic options. Ceftolozane-tazobactam is a newer type of antibiotic that has been shown to be safe and effective in infections caused by several types of resistant bacteria that can cause serious infections in individuals with low blood count. This study aims to examine the effectiveness of this antibiotic in these types of patients. Patients with blood cancer and those who have received a bone transplant will be offered the option to join this study if they develop unexplained fever. If informed consent is granted, they will receive ceftolozane-tazobactam on top of the usual care that such patients receive. The patients will then be followed very closely to check their response to the treatment and if they develop any untoward events. The study will include 164 patients over an estimated 2 year period. The study is funded by Merck & Co, the company that manufactures the study antibiotic. However, Merck & Co. will not be involved in the actual running of the study, the collection of the study results or their analysis and interpretation. The study protocol has been reviewed and approved by an independent research oversight committee.

The purpose of this study is to determine the safety and effectiveness of UCBT to treat patients with lymphoid hematological diseases and to see if this treatment can decrease the incidence of leukemia relapse, GVHD and infections. These patients have a type of blood cell disorder that is very hard to cure. This treatment that is being used in this trial is known as a stem cell transplant. This treatment might help the patient live longer without the disease. It uses much stronger doses of drugs and radiation to kill the diseased cells that could be given without the transplant. We also think that the healthy cells from the donor may help fight any diseased cells left after the transplant. For the transplant to take place, we will administer stem cells from a 'donor' whose cells best 'match' the patient's. In this study umbilical cords will be the source of the stem cells. Before the transplant, two very strong drugs plus total body irradiation will be given to as preconditioning. This treatment will kill most of your blood-forming cells in the bone marrow. The patient will then get then healthy stem cells. If the patient has the disease in the central nervous system (CNS), they will receive radiation to the head and spine before starting the conditioning. This is to try to get disease control in the CNS. Radiation will not be given for children under 2 yrs old. Currently, many umbilical cord blood units are available in public banks for transplantation in patients lacking bone marrow donors. UCB transplants (UCBT) may offer several advantages over adult bone marrow or peripheral blood stem cell transplants, including: rapid availability, absence of donor risk, low risk of transmissible infectious diseases, low risk of acute GvHD (Graft vs. Host Disease) The three main causes of death after umbilical cord blood transplantation for these kind of disorders are graft failure, infection and disease relapse. In this study we are trying to address these three problems: To help improve engraftment we will add the drug Fludarabine to Cytoxan and total body irradiation. Fludarabine is a very strong medicine. We will try to decrease infections and reduce leukemia relapse by using fludarabine instead of antithymocyte globulin (ATG).

The purpose of this trial is to determine if selectively removing only a small subset of T cells, called CD8+ T cells, is safe and if it can reduce the risk of graft versus host disease (GVHD) without losing the anti-cancer effects.

The primary objective of this phase 2, multicentric, placebo-controlled double-blind, randomized study is to evaluate the efficacy of the combination of hydroxychloroquine and azithromycine on the viral load drop at day 5 among patients with COVID-19 and hematological malignancies.

To evaluate the safety and tolerability of escalating doses of ERAS-007 or ERAS-601 in combination with other cancer therapies in study participants with hematologic malignancies. To determine the Maximum Tolerated Dose (MTD) and/or Recommended Dose (RD) of ERAS-007 or ERAS-601 administered in combination with other cancer therapies. To evaluate the preliminary efficacy of ERAS-007 or ERAS-601 in combination with other cancer therapies in study participants with hematologic malignancies. To evaluate the PK profiles of ERAS-007 or ERAS-601 and other cancer therapies when administered in combination.

This trial will study how safely the tazemetostat works with other therapies in various hematological malignancies. Hematologic malignancies are cancers that most often begin in the bone marrow or lymph nodes where blood precursors are produced. They are often called blood cancers and fall into three categories: leukemia, lymphoma and myeloma. Tazemetostat has been found to be a safe and effective drug that works in patients with follicular lymphoma where the disease has come back after treatment (known as relapsed) and when other treatment no longer works (known as refractory). Combining tazemetostat with other treatments may work better in treating patients with hematological malignancies and may improve disease response and durability of response.

This study is to evaluate the effect of leucovorin in preventing or reducing Folotyn-related Grade 2 or higher oral mucositis.

Therapeutic exploratory study to evaluate safety, open, nonrandomized, multicentre, prospective, of cohort of patients who will receive different doses of allo-depleted lymphocytes . This project joins in this pioneering worldwide initiative with its own technology based on the use of proteasome inhibitors in vitro, which advantages are, over other methods described, the continuing viability of regulatory T cells and the use of a product to generate allo-depletion that, contrary to those reported by other research groups, it does not pose problems from the point of view of its use or toxicity as we employ a drug widely used clinically by intravenous administration.

Two part study to evaluate the safety, tolerability, pharmacokinetics, and efficacy (in Part 2 only) of KRP203 in patients undergoing allogeneic hemopoietic stem cell transplant for hematological malignancies

The investigators propose a nonrandomized, Phase I study to assess the safety of infusion of NK cells that will be selected from sibling donors and infused to patients with hematological malignancies early following allogeneic stem cell transplantation.
