Active clinical trials for "Hematologic Neoplasms"

This pilot phase I trial studies the side effects and best dose of fructooligosaccharides in treating patients with blood cancer who are undergoing donor stem cell transplant. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Nutritional supplements such as fructooligosaccharides may reduce the incidence of graft-versus-host disease in patients with blood cancer undergoing donor stem cell transplant.

Phase II trial evaluating the safety & efficacy of Atorvastatin for prophylaxis of Acute Graft Versus Host Disease (GVHD) in patients with hematological malignances undergoing human leukocyte antigen (HLA)-Matched Related Donor Hematopoietic Stem Cell Transplant (HSCT).

The main purpose of this study is to examine techniques to help patients cope better with the stem cell/bone marrow transplant procedure.

Pneumocystis jiroveci pneumonia (PcP) increased in non HIV immunocompromised patients. Mortality remains high for those patients with comorbidities (50% for patients with the most severe Pneumocystis pneumonia). Physiopathology, characteristics and outcome of PcP in non-HIV patients remains different from those in HIV patients. Steroids in HIV patients with PcP has been associated with decreased mortality but in non-HIV patients, adjunctive steroids remains controversy. Some retrospective studies in that field did not find any beneficial effects of steroids ((1mg/kg/jour d'Equivalent Prednisone (EP)). However, all the studies were retrospective, non randomised studies including various underlying disease and severity of PcP was variable. Moreover, dosage and delay of steroids were variable leading difficult to interpret all the results. The investigators want to demonstrate the beneficial effect of steroid during PcP in non-HiV immunocompromised patients with a double blinded randomised clinical trials comparing adjunctive steroids to placebo.

Registry participants with advanced malignancy or myelodysplasia will have a sample of their tumor or tissue analysed for genetic alterations using next generation sequencing (NGS) performed in a lab that has been certified to meet a high quality standard. Treatments and outcomes will be reported to the registry to allow further understanding of how genetic differences can lead to better diagnosis and treatments.

This is a prospective study of the safety and efficacy of nivolumab for the treatment of relapsed or residual haematological malignancies after allogeneic stem cell transplantation (alloSCT). Eligible patients will receive nivolumab at a dose of 3mg/kg intravenously every 2 weeks. The primary objective is to evaluate the incidence, severity and treatment responsiveness of GVHD following nivolumab treatment post-alloSCT.

This study will evaluate the safety of infusing an anti-MiHA T cell line in patients suffering from an hematologic malignancy that has relapsed following hematopoietic stem cell transplantation from a matched donor.

Interventional, open label, Phase I/II, Safety and Proof-of-Concept Study, with a follow up period of 180 days after the transplantation of ApoGraft.

CD19 is expressed in most B malignant tumors, especially in the former B cells ALL. This makes CD19 a natural target of immunotherapy. In terms of safety, the lack of B cells caused by CD19 targeted therapy will not cause life-threatening side effects (of course, Ig supplementation is necessary in the long-term B cell inhibition therapy). Moreover, the number of B cells can be restored after removing anti-CD19 treatment measures (such as anti-CD19 CART cells). In addition, CD19 has been chosen as the target of B-ALL therapy for the following reasons: ① as the BCR signal "amplifier", CD19 plays a role in PAX-5-mediated tumor formation; ② by activating MYC (as the oncogene controlled by PAX-5, C-MYC plays a key role in promoting the malignant proliferation of B cells), CD19 can cause B-ALL formation. Based on the above reasons, CD19 has become an ideal target in the treatment of B-cell cancer.

Unmanipulated allogenic peripheral blood stem cell transplantation (allo-PBSCT) has been an established treatment to cure high-risk leukemia/lymphoma. Relapse is the main cause of treatment failure for patients with relapsed/refractory disease or with very high-risk gene mutations such as TP53, TET2 and DNMT3a. Donor lymphocyte infusion (DLI) is an option to reduce relapse after allo-PBSCT for very high-risk disease without effective targeted therapy. In this study, the investigators aimed to compare the safety and efficacy of prophylactic DLI with G-CSF-primed peripheral blood progenitors for prevention of relapse after allo-PBSCT in patients with very high-risk leukemia/lymphoma.
