NCT ID: NCT05947851 Recruiting - Clinical trials for Leukemia, Lymphocytic, Chronic, B-Cell

A Study of Nemtabrutinib Plus Venetoclax vs Venetoclax + Rituximab (VR) in Second-line (2L) + Relapsed/Refractory (R/R) Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL) (MK-1026-010/BELLWAVE-010)

Phase: Phase 3
Study type: Interventional

The primary study hypotheses are that the combination of nemtabrutinib plus venetoclax is superior to VR with respect to progression-free survival (PFS) per 2018 International Workshop on Chronic Lymphocytic Leukemia (iwCLL) criteria as assessed by blinded independent central review (BICR).

Start date: December 1, 2023
Phase: Phase 1/Phase 2
Study type: Interventional

This is a single arm, open-label, multi-center, phase I/II study to determine the engraftment, safety and clinical activity of allogeneic CARCIK-CD19 cells in adult and pediatric patients with relapsed/refractory mature B-cell neoplasia expected to express CD19 i.e. B-cell NHL and CLL. CARCIK-CD19 will be produced from the peripheral blood of an at least haploidentical familial donor.

NCT ID: NCT05610228 Recruiting - CLL Clinical Trials

Study of the Metabolism in the Lymphatic Niche of CLL

Start date: November 7, 2018
Phase:
Study type: Observational

Chronic lymphoid leukemia (CLL) is the most common adult leukemia that is characterized by a malignant monoclonal accumulation of tumoral and quiescent B cells in the peripheral blood. In advanced stages of the disease (Binet stage C), this population invades the bone marrow (BM) and proliferate into the lymphoid organs that results in widespread adenopathy. Richter's transformation is a most aggressive serious complication of CLL (transformation of the disease into an aggressive lymphoma) detected based on TEP/CT (Positron Emission Tomography/ computerized tomography) that shows highly derived glucose consumption by cancer cells. Clinical data from CLL patients with disease acutisation showed hypermetabolic lymphadenopathy with high standardized uptake value (SUV) whereas there is low grade tracer uptake into BM. We supposed that the tumor microenvironment of the lymphatic niche promotes the proliferation and glycolytic activity of CLL cells which become particularly resistant to treatment. The development of an ex-vivo tumor model that reproduces the microenvironment of the lymph node niche appears essential to identify and validate new therapeutic targets because despite the therapeutic arsenal available some patients still relapse or are refractory to treatment. Our objectives are to i / Characterize this niche of resistance by the development of an ex-vivo tumor model and ii / Evaluate in-vitro the effectiveness of the association of current treatments (RFC, Ibrutinib or Venetoclax) with anti-metabolic therapies (inhibitors of glycolysis) Our lab is developing an ex-vivo models of the lymphatic niche in CLL based on co-cultures of leukemic cells from patients stimulated with CpG ODN and IL2 with primary human lymphatic fibroblasts (HLF) (EC 12PP15). This co-culture has never been described in the literature and allows us to study the lymphatic niche of CLL patients. Lymph node (LN) exploration in CLL requires invasive access and does not bring any additional information in initial diagnosis. Then, we validated our co-culture model using complementary approaches: increased viability, proliferation, and resistance to Ibrutinib, associated with increased production of anti-apoptotic proteins such as MCL1 and BCL2 after 48 hours of co-culture. Secondly, we studied the metabolism in this resistance niche. We find an increased production of lactate and an acute consumption of glucose, associated with a strong metabolic activation detected by SEAHORSE and by the production of glycolysis enzymes such as hexokinase 2. Our study constitutes an original project because it characterized the energy metabolism of the CLL lymphatic niche by developing an original ex-vivo model and enhanced our understanding of the contribution of the specific microenvironment in the dissociation of metabolic activity using SUV max in BM and lymphatic niche. Anti-metabolic therapies are efficient on co-culture CLL cells and could be an alternative for refractory or relapsed patients under current treatment.

NCT ID: NCT03868722 Recruiting - CLL Clinical Trials

Acalabrutinib and Venetoclax Treatment of Newly Diagnosed Patients With CLL at High Risk of Infection or Early Treatment

Start date: October 11, 2019
Phase: Phase 2/Phase 3
Study type: Interventional

Many patients with CLL have a weakened immune system due to their disease. It increases their risk of developing serious, treatment-requiring infections such as blood poisoning or pneumonia, which in the worst case may end with fatal outcomes. Serious infections due to CLL are responsible for one third of all deaths among CLL patients. PreVent-ACaLL study will investigate whether a combination of two known types of cancer drugs can reduce the risk of infection and thus mortality when given preventively to newly diagnosed CLL patients. A newly developed register-based computer model can predict which patients are at high risk in order to develop infections as a result of their CLL. A preventive treatment might be initiated before patients need chemotherapy. In this way, the cancer disease might be "reset" so that the immune system, which is inhibited by CLL, is restored and the risk of fatal infections is minimized.
