This trial is a single-center, single-arm, prospective clinical study to investigate the efficacy and safety of zanubrutinib maintenance therapy in patients with diffuse large B-cell lymphoma (DLBCL) in Initial remission. The patients were divided into two categories: 1) Zanubrutinib maintenance therapy was started after R-CHOP induction and consolidation therapy reached maximum efficacy; 2) Initiate zanubrutinib maintenance therapy after maximal response to induction and consolidation therapy with or without rituximab (R-chemo). Therefore, the data in this study will reflect the efficacy and safety of zanubrutinib in the maintenance treatment of DLBCL patients with initial remission, and will provide new insights into the clinical application of zanubrutinib.
To evaluate the safety and efficacy of mitoxantrone hydrochloride liposome in combination with rituximab and lenalidomide in the treatment of relapsed and refractory diffuse large B-cell lymphoma (DLBCL).
Immunotherapy became in recent years a major innovation in the care of cancer patients, with unprecedented improvement in complete response and survival, particularly in hematological cancers. Since 2018, patients with relapsed or refractory lymphoma can benefit from immunotherapy based on CAR-T cells (Chimeric Antigenic Receptor - T cells), drugs derived from gene therapy and products from the patient's own T cells. The efficacy of these drugs, their development in more and more indications and in continuous earlier lines of treatment, their unprecedented adverse effects and their very high cost justify the search for predictive factors of efficacy and tolerance in order to optimize their use and benefit the greatest number of eligible patients. A better understanding of quality of life and its determinants in patients who received CAR-T cells could play a major role in predicting efficacy and tolerance. Quality of life data have indeed been deemed insufficient in phase 1-2 trials which have demonstrated the benefit of CAR-T cells in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) in 3rd line of treatment or more and led to obtaining their marketing authorization. It is therefore necessary to assess the quality of life of patients treated in routine care with CAR-T cells. The European Qualitop project aims, from self-questionnaires, to explore the quality of life during the 2 years following the initiation of immunotherapy with a multidimensional approach integrating genetic factors, lifestyle habits and psychosocial determinants of patients. In this context, the Qualitop CAR-T study is a prospective non-comparative real-life study aimed at describing the multidimensional quality of life, its psychosocial determinants and drug consumption in patients with relapsed or refractory DLBCL treated with CAR -T cells.
Diffuse large B cell lymphoma is the most common malignant lymphoid hemopathy. More than half of the patients will be cured with an RCHOP-type immunochemotherapy protocol (Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, Prednisone). Monitoring of adverse effects, risk of relapse and quality of life are essential in overall management. Patients are the best candidates to report them. Managing these events should improve quality of life and reduce costs. The aim of this study is to assess the feasibility of monitoring these events by a web application (Oncolaxy©) and to compare it with a control population in the context of a randomized pilot study including 80 patients per arm with diffuse large cell B lymphoma in first-line treatment with R-CHOP.
This study is a phase I multicenter, single arm, open, dose increasing, single treatment clinical study. This study plans to recruit a total of about 10-16 adult patients with CD19 positive recurrent or refractory DLBCL for a single autologous car-t cell therapy. There are three dose groups in the study. The first dose group has one patient. If there is no dose limiting toxicity (DLT), it can be increased to the second dose group, otherwise it will continue to be enrolled according to the "3 + 3" method; The follow-up dose group is conducted according to the traditional "3 + 3" design, that is, three subjects are first enrolled in a dose group. If there is no dose limiting toxicity (DLT) in the three patients in the dose group, it can be increased to the next higher dose after completing the DLT observation period; If DLT occurs in 1 of the 3 patients in the dose group, it is necessary to continue to enroll 3 patients in the dose group for DLT observation. The highest dose level of DLT in less than or equal to 1 of the last 6 confirmed patients will be defined as MTD. The safety of car-t treatment was evaluated by observing the adverse events after cell therapy; Evaluate the effectiveness of car-t treatment compared with the results or historical data of the patient's own previous standard treatment regimen. Blood and bone marrow were collected before and 12 months after cell infusion, the number and activity of car-t cells were detected, and the pharmacokinetics (PK) of car-t cells was evaluated.
This study is a single-armed, open-label,multicenter Phase 1/2 study to evaluate the safety and efficacy of CT120 in subjects with relapsed/refractory B-cell non-Hodgkin's lymphoma.
This phase I trial evaluates the side effects and usefulness of axicabtagene clioleucel (a CAR-T therapy) and find out what effect, if any, it has on treating patients with HIV-associated aggressive B-cell non-Hodgkin lymphoma that has come back (relapsed) or not responded to treatment (refractory). T cells are infection fighting blood cells that can kill tumor cells. Axicabtagene ciloleucel consists of genetically modified T cells, modified to recognize CD-19, a protein on the surface of cancer cells. These CD-19-specific T cells may help the body's immune system identify and kill CD-19-positive B-cell non-Hodgkin lymphoma cells.
The specific immune response to SARS-CoV-2 includes a humoral response - specific IgM appearing 5 days after the onset of symptoms while IgG appears after 14 days - and a T lymphocyte component, with specific activated CD8 and CD4 T lymphocytes (Dan JM et al., Science 2021). Mortality from infection varies greatly depending on the age of the affected subjects and their comorbidities including a history of cancer (Liang W et al, 2020). Among these cancers, a history of malignant hemopathy in the 5 years preceding the onset of Covid-19 increases the risk of death by a factor of 3 (OpenSAFELY collaborative 2020). Among them, lymphoid hemopathies induce hypogammaglobulinemia and / or lymphopenia. These factors combined with chemotherapy and immunotherapy treatments promote the development of infections in affected individuals. Among these, are the anti-CD20 monoclonal antibodies, widely prescribed for treating B-cell non-Hodgkin lymphomas (B-NHL). They induce a deep and lasting B-cell lymphopenia, which can promote infections (Maschmeyer G et al, 2019). They reduce the production of antibodies and the constitution of memory responses to a new pathogen or to a vaccination. In addition, B lymphocytes likely have a key immunomodulatory role in the control of viral infections. We conducted a retrospective study in 89 patients with lymphoma and Covid-19 after the first phase of the epidemic in different centers in the Île-de-France and eastern France regions (Lamure S et al. , 2020). With a 6-month follow-up, we showed a pejorative prognostic impact of anti-CD20 monoclonal antibody treatment on Covid-19-related mortality (Duléry et al, 2021). Vaccination of these at-risk patients is therefore essential. A growing concern is how patients with B-NHL who have been vaccinated with a SARS-CoV-2 mRNA vaccine are protected against infection, depending on whether or not they have received anti-CD20 monoclonal drugs and / or chemotherapy. Knowing the medium-term immunological evolution after vaccination against SARS-CoV-2 in patients with B-cell NHL is necessary in order to be able to adapt the therapeutic and vaccine recommendations. The main objective of this study is to determine how recent treatment (in the year before vaccination) with anti-CD20 monoclonal antibody modifies the immune response after vaccination against SARS-CoV-2 in adults with B-NHL compared to patients who have not recently been exposed to this immunotherapy.
