Active clinical trials for "Lymphoma"

The purpose of this study is to find out whether people with CLL or SLL who are currently receiving treatment with ibrutinib can stop treatment and remain off-treatment for at least 12 months, if they have achieved complete or partial remission of their disease.

This study will help researchers learn more about non-Hodgkin's lymphoma and Hodgkin's lymphoma and how it is treated in Kenya. Researchers want to see if having certain viruses like Epstein Barr Virus (EBV), Human Immunodeficiency Virus (HIV), and Kaposi's Sarcoma Herpes Virus (KSHV) affects lymphoma. Patients in Kenya who agree to be in this study will let the resesarchers look at their medical record, follow their normal cancer care, and have blood drawn to look at different proteins and viruses. Researchers would also like to look at part of the original tumor that was taken out of each patient. Some of these samples will be stored at Kenyatta National Hospital and research will be done on them later. This study does not involve any change in treatment, but only allows the study team to follow how a patient in Kenya with lymphoma is treated.

Primary Objectives: To enroll and obtain, through questionnaires, risk factor information on all study participants to develop detailed demographic, epidemiologic and behavioral profiles. To assess the influence of relevant epidemiologic covariates such as age, gender, smoking and family history of cancer on the panel of susceptibility biomarkers. To evaluate the role of genomic instability in development of lymphomas.

France was gradually affected by SARS-Cov-2 from January 2020; it evolved in an epidemic mode in March and April 20. During the 1st phase of the epidemic, more than 250 000 cases of Covid-19 have been confirmed in France resulting in the death of more than 30,000 patients. Mortality from infection varies greatly depending on the age of the affected individuals and their comorbidities including a history of cancer. We conducted a retrospective study in 89 patients with lymphoma and Covid-19 during the first phase of the epidemic and showed a 30-day mortality of 29%. Mortality was higher in patients over 70 years of age and in a situation of relapsed or refractory disease. Lymphoma-induced hypogammaglobulinemia and / or lymphopenia as well as chemotherapy and immunotherapy treatments are known to promote the development of infections in affected individuals. Among these, anti-CD20 monoclonal antibodies, widely prescribed to treat B-cell non-Hodgkin lymphomas (B-NHL) induce a rapid depletion of over 95% of mature CD20 + B cells. This can alter the production of antibodies, and the constitution of memory responses to a new pathogen. Also, B lymphocytes have a key immunomodulatory role in the control of viral infections. The specific immune response to SARS-CoV -2 and its evolution remain under characterization. Regardless of their neutralizing capacity, specific IgM appear 5 days after the onset of symptoms while IgG appear after 14 days. The immune response to SARS-CoV-2 also includes a T lymphocyte component, with an increase, among circulating lymphocytes, of activated CD8 and CD4 T lymphocytes. Data are still lacking on the specific response of CD4 and CD8 T lymphocytes against SARS-CoV-2, but these responses probably play a crucial role in virus clearance as well as in the immunopathology associated with SARS-CoV-2. Therapeutic depletion of B lymphocytes before acute infection may alter the generation of primary and functional responses. Therefore, a growing concern is whether patients with B-NHL who have acquired an infection with SARS-CoV-2 are protected against re-infection in the same way when they have or have not received anti-CD20 monoclonal antibodies. Analyzing the clinical and immunological evolution of Covid-19 in patients with B-NHL is useful to adapt the treatment recommendations in their regard according to the risk of severe form of Covid-19 . This is a multicenter, prospective study to determine whether treatment with monoclonal anti-CD20 antibodies in patients with B-cell NHL modifies the clinical and immunological course of Covid-19.

The goal of this clinical research study is to learn if positron emission tomography (PET)/computed tomography (CT) scanning can be used to detect mantle cell lymphoma in the colon. Researchers want to learn if PET/CT scanning can produce good-quality images and/or find the exact locations of lymphoma in the body. Primary Objective is to determine if combined CT colonography and full body PET scan is technically feasible and can produce diagnostic scans as well as accurate anatomic coordination for detection of mantle cell lymphoma involvement of the colon.

Background: - Autoimmune lymphoproliferative syndrome (ALPS) is a genetic disorder of the lymph system. People with ALPS often have swollen lymph nodes, especially in the neck and armpit. They also have a much higher risk of developing lymphoma. It is not always easy to determine whether the swollen lymph nodes are caused by ALPS or by lymphoma. Researchers want to see whether different imaging studies can show the difference between ALPS and lymphoma. The studies used will be positron emission tomography (PET) and computed tomography (CT). Researchers will use a drug called fluorodeoxyglucose (FDG) to look at the lymph nodes. Objectives: - To see how well imaging studies can distinguish between swollen lymph nodes caused by ALPS or by lymphoma. Eligibility: Individuals must be 5 years of age or older and enrolled on the National Institutes of Health natural history study of ALPS. Participants should either have lymphoma or have symptoms that suggest possible lymphoma. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Participants will have an FDG-PET/CT scan. It will be performed according to standard procedures. If the results of the scan do not show lymphoma, participants will stay on the study for 1 year for clinical follow up. They may have a second FDG-PET/CT scan if there is a change in symptoms. Such changes include further enlargement of lymph nodes, unexplained fevers, or weight loss. If the results of the scan show evidence of new or worsening lymphoma, treatment on this study will end. Further tests based on clinical symptoms, including a lymph node biopsy, may be done under the ALPS natural history study to rule out or make a diagnosis of lymphoma.

To collect and store blood and biopsy samples obtained from CD or UC patients exposed to adalimumab and diagnosed with Hepatosplenic T-cell Lymphoma (HSTCL), for the purpose of identifying potential biomarkers and genetic mutations in patients who have developed HSTCL.

Provide compassionate use of odronextamab

The goal of this study is to provide access to axicabtagene ciloleucel for patients diagnosed with a disease approved for treatment with axicabtagene ciloleucel, that is otherwise out of specification for commercial release.

The primary objective of this protocol is to provide expanded access to tabelecleucel to participants with Epstein-Barr virus-associated diseases and malignancies for whom there are no other appropriate therapeutic options, and who are not eligible to enroll in clinical studies designed to support the development and registration of tabelecleucel.
