Filter by:This phase III trial compares adding a new anti-cancer drug (venetoclax) to the usual treatment (ibrutinib plus obinutuzumab) in older patients with chronic lymphocytic leukemia who have not received previous treatment. The addition of venetoclax to the usual treatment might prevent chronic lymphocytic leukemia from returning. This trial also will investigate whether patients who receive ibrutinib plus obinutuzumab plus venetoclax and have no detectable chronic lymphocytic leukemia after 1 year of treatment, can stop taking ibrutinib. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Immunotherapy with obinutuzumab may induce changes in body's immune system and may interfere with the ability of cancer cells to grow and spread. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving ibrutinib and obinutuzumab with venetoclax may work better at treating chronic lymphocytic leukemia compared to ibrutinib and obinutuzumab.
This phase II trial studies the how well fractionated gemtuzumab ozogamicin works in treating measurable residual disease in patients with acute myeloid leukemia. Gemtuzumab ozogamicin is a monoclonal antibody, called gemtuzumab, linked to a chemotherapy drug, called ozogamicin. Gemtuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD33 receptors, and delivers a chemotherapy known as calicheamicin to kill them.
This phase Ib/II trial studies the side effects and best dose of venetoclax in combination with quizartinib and how well they work in treating patients with acute myeloid leukemia that has come back or does not respond to treatment, and who are FLT3-mutation positive. Venetoclax and quizartinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Descriptive study of acute leukemia patients. Bone marrow aspirate or peripheral blood samples will be analyzed by next-generation sequencing for novel gene signatures and variations in transcriptional and epigenetic regulatory elements such as ARID5B and SALL4 variants.
This research study is studying a targeted therapy combined with chemotherapy as a possible treatment for acute myeloid leukemia (AML) or high risk myelodysplastic syndrome (MDS). The drugs involved in this study are: - Prexasertib (LY2606368) - Mitoxantrone - Etoposide - Cytarabine
The purpose of this study is to evaluate whether addition of a low dose of total body irradiation (TBI) to a standard preparation for transplant [total lymphoid irradiation (TLI) and anti-thymocyte globulin (ATG)] conditioning will help to augment donor chimerism without reducing tolerability of this regimen or increasing the risk of graft-vs-host disease (GVHD)
Ibrutinib, a first-in-class Bruton Tyrosine kinase (BTK) inhibitor, has become an established treatment in relapsed/refractory chronic lymphocytic leukemia (CLL). However, despite a considerable improvement of Progression Free Survival (PFS) and Overall Survival (OS) in comparison with historical controls, the prognosis of patients with 17p deletion (del17p) remains a concern, as it is clearly much less favourable than that of patient without del17p. Again, TP53 mutations correlated to poorer prognostic in Relapsed/Refractory (R/R) CLL patients treated with ibrutinib (Brown JR et al,2018). Despite these therapeutic advances, the treatment of CLL with TP53 disruption thus remains a difficult issue that warrants evaluation of alternative treatment strategies, in particular the use of ibrutinib in combination with other agents. A body of evidence suggests that targeting the extracellular molecule CD38 might be an interesting option. CD38 is a transmembrane glycoprotein with multiple receptor and enzymatic functions. The interaction of CD38 with its ligand CD31 (also known as Platelet Endothelial Cell Adhesion Molecule (PECAM-1)) not only plays a role in the binding and the migration of leucocytes through the endothelial cells wall but also triggers the activation of intracellular pathways involved in the differentiation and activation of B cells. Previous results strongly suggest that CD38 favours the expansion of CLL clones not only directly by transducing a proliferation signal but also by directing them to anatomic sites where they find favourable conditions for proliferation and survival. Daratumumab is a first-in-class human IgG1ΔΈ monoclonal antibody (mAb) that binds CD38-expressing malignant cells with high affinity. Daratumumab induces tumor cell death through multiple mechanisms such as antibody-dependent cell-mediated cytotoxicity (ADCC), complement dependent cytotoxicity (CDC), antibody-dependent cellular phagocytosis (ADCP) and induction of apoptosis (de Weers et al, 2011). Recent data show that daratumumab may also display an immunomodulatory effect through depletion of a subset of immunosuppressive CD38+ Tregs (Krejcik et al, 2016). Early-stage clinical trials found daratumumab to be safe and to display encouraging clinical activity as a single agent in relapsed/refractory multiple myeloma (MM) patients (Lockhorst et al 2016, Lonial et al, 2016). Overall response rate was 31%, with rapid (median 1 month) and durable responses in this heavily pretreated MM population. Interestingly, no patient discontinued the treatment because of drug-related adverse events. These results led to approval of daratumumab in relapsed/refractory MM in December 2015. The clinical efficacy of daratumumab along with its very favourable safety profile supports its investigation in other lymphoproliferative malignancies. In particular, the expression of CD38 in poor prognosis CLL and the key role of CD38 in CLL biology provide a basis for examining the potential of daratumumab in this disease. In preclinical studies, (Matas-Céspedes et al, 2016; Manna et al, 2017) Daratumumab efficiently kills CLL cell lines and patient-derived CLL cells by ADCC and ADCP in vitro. Daratumumab modulates CLL-T reg levels and increase cytotoxic effector T cells. Rationale for combining ibrutinib with daratumumab: These data suggest that combining ibrutinib with daratumumab might have a synergistic or additive effect. Both drugs inhibit B cell receptor (BCR) signalling via two different converging pathways, i.e. BTK and CD38/ZAP70/ERK (Deaglio et al, 2007). In vitro, Manna et al have shown that daratumumab is able to modulate BCR signaling. Interestingly, the ibrutinib /daratumumab combination significantly enhanced mitochondrial-mediated apoptosis bth in CD38 high and CD38 low CLL cells (Manna et al, 2017). Altogether, this provides a rationale for evaluating the safety and efficacy of the association of daratumumab with ibrutinib in high-risk relapsed/refractory patients for whom the standard-of-care using ibrutinib as a single agent has demonstrated limitations in terms of long-term disease control. Primary objective of the study: to determine the efficacy of a treatment combining daratumumab and ibrutinib in a poor risk population of relapsed CLL patients with TP53 dysfunction. Secondary objectives of the study : to determine the safety profile of daratumumab in combination with ibrutinib in CLL patients. Inclusion period: 24 months Treatment duration (ibrutinib + daratumumab): continuous, until disease progression or unacceptable toxicity. Follow-up period: will begin once the subject discontinues study treatment, during 2 years.
This study is designed to compare the overall response rate of zanubrutinib versus ibrutinib in participants with relapsed/refractory chronic lymphocytic leukemia or small lymphocytic lymphoma.
This is a long-term follow up study evaluating the safety of BPX-501 T cells (rivogenlecleucel) and infused in pediatric patients previously enrolled on the BP-004 study.
The purpose of this study was to determine the safety and tolerability of gilteritinib given in combination with atezolizumab in participants with relapsed or treatment refractory FMS-like tyrosine kinase 3 (FLT3) mutated AML and to determine the composite complete remission (CRc) rate for participants who either discontinued the study or completed 2 cycles of gilteritinib given in combination with atezolizumab. This study also evaluated pharmacokinetics (PK), response to treatment, remission and survival. Adverse events (AEs), clinical laboratory results, vital signs, electrocardiograms (ECGs), and Eastern Cooperative Oncology Group (ECOG) performance status scores were also assessed.
