Filter by:The purpose of this study is to compare the efficacy and safety of pirtobruitinib (LOXO-305) to ibrutinib in participants with CLL/SLL. Participants may or may not have already had treatment for their cancer. Participation could last up to six years.
AINV18P1 is a Phase 1 study where palbociclib will be administrated in combination with a standard re-induction platform in pediatric relapsed Acute Lymphoblastic Leukemia (ALL) and lymphoblastic lymphoma (LL). LL patients are included because the patient population is rare and these patients are most commonly treated with ALL regimens. The proposed palbociclib starting dose for this study will be 50 mg/m^2/day for 21 days.
The purpose of this study is to measure, in pilot/observational study, panels of circulating proteins in real time at the onset of neutropenic fever/infection in patients with acute or chronic leukemias undergoing chemotherapy or other biologic treatment. And to generate preliminary trend results in panels of circulating proteins longitudinally during the period of neutropenia and to correlate those values to clinical/laboratory data and patient outcomes.
The primary objective of this study is to see if enzastaurin affects the pGSK3 beta level in B-cell chronic lymphocytic leukemia (B-CLL) cells.
Pre-transplant conditioning will include Fludarabine and dose-escalated Busulfan on days -6, -5, -4, and -3. Daily treatment doses will be adjusted to achieve target AUCs (area under the plasma concentration time curve). Day 0 is the day of hematopoietic progenitor cell reinfusion. Supportive care will be based on institutional guidelines. Blood samples will be collected for dose modification based on the AUC levels. Dose escalation will proceed to determine the maximally tolerated level or AUC to evaluate the potential therapeutic benefit of higher doses of busulfan.
This study is a multicenter trial of treatment for young ALL patients. All ALL patients will receive the same steroid pre-phase in order to evaluate sensitivity or resistance. Then, patients will be included into 3 specific trials according to biological features (immunophenotype, cytogenetics, and molecular biology). Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL) 2005: - T ALL or B ALL non Ph (N=810 patients planned). - GRAALL 2005 R: B ALL non Ph CD20+ (N=220 patients planned). - GRAAPH 2005: ALL Ph+ (N=270 patients planned)
Bone marrow failure syndromes (BMFS) are rare disorders characterized by dysfunctional hematopoietic stem cells, which give rise to all red and white blood cells. The deficiency of blood cells, or cytopenia, caused by this malfunction leads to an assortment of diseases and disorders, all of which are characterized as BMFS. Because these diseases are rare, conducting research on them is difficult, and standards of treatment for most BMFS have yet to be developed. This study will collect clinical and laboratory data from people with BMFS to identify the characteristics and biological markers associated with these diseases over time. This information will assist doctors and researchers to develop better therapies and diagnostic tests that will help improve the management of BMFS and cytopenias.
A phase I trial in patients with relapsed or refractory leukemia of a human monoclonal antibody that kills B cell acute lymphoblastic leukemia. Trial will study safety, pharmacokinetics, and anti tumor activity of the antibody given as a single agent and with vincristine.
T-cell and B-cell depletion in allogeneic peripheral blood stem cell transplantation by using immunomagnetic negative and positive selection procedures Background: Removal of T-cells from the donor graft (T-cell depletion) offers the possibility for prevention of GVHD and subsequently less transplant related morbidity and mortality after allogeneic stem cell transplantation (SCT). There are several techniques to deplete T-cells from the stem cell grafts e.g. physical, immunological and combined physical / immunological separation methods. All these techniques result in a stem cell graft with sufficient CD34+ stem cells combined with an adequate depletion of T and B cells. CD34+ selected stem cell grafts are very pure and do not contain any additional cell populations. In contrast, CD3+/CD19+ depleted grafts still contain NK-cells, monocytes and dendritic cells that are part of the innate immune system. Theoretically,the presence of these cells may positively influence immunological reconstitution and the graft-versus-leukaemia (GVL) effect, respectively, resulting in improved outcome after SCT Objectives: To evaluate the differences in immunological reconstitution, transplant related mortality, disease-free survival and overall survival after T-cell depleted allogeneic SCT for haematological malignancies using either immunomagnetic CD34+ selection or immunomagnetic CD3+/CD19+ depletion using the CliniMACS system in approximately 270 consecutive patients. Additionally in this study in 20 consecutive patients the kinetics of NK-cel reconstitution and differences in NK-cell repertoire will be monitored. NK-cell mediated anti-tumor reactivity will be monitored in patients transplanted with and without NK-cells in the stem cell graft (CD3+/CD19+ depletion, versus CD34+ selection). Secondary objectives are to evaluate the clinical relevance of minor histocompatibility-specific cytotoxic T-cell responses for the GVL effect, the kinetics of NK-cell reconstitution and differences in NK-cell repertoire using the different T-cell depletion protocols. Design: Single center prospective randomised phase III study Population: Patients eligible for allogeneic SCT according to the standard criteria of our institution who will receive an allogeneic T- and B-cell depleted SCT with peripheral stem cells of an HLA-identical sibling donor or an HLA-identical unrelated voluntary (VUD) donor. Intervention: T-cell depletion will be conducted using two different techniques: either immunomagnetic CD34+ selection or immunomagnetic CD3+/CD19+ depletion. Endpoints: Primary endpoints are immunological reconstitution, relapse, disease free survival and overall survival. Secondary endpoints: NK-cell reconstitution and NK-cell mediated anti-tumour reactivity. Cytotoxic T-cell responses for the GVL effect. Estimated efforts and risks for participating patients: We don't expect any extra patient efforts or risks because T-cell depletion is a standard procedure in our clinic for many years. There is extensive experience with immunological T-cell depletion techniques. We hypothesize CD3+/CD19+ depletion will favour stem cell transplant outcome. Immunological and molecular biological studies will be performed on blood samples already obtained as part of the standard protocol.
The purpose of this study is to evaluate the effect of treatment with epoetin alfa versus placebo on the percentage of red blood cells in anemic patients with chronic lymphocytic (white blood cell) leukemia and its effect on the patients' quality-of-life. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production.
