Active clinical trials for "Lymphoma, Non-Hodgkin"

The purpose of this study is to determine the optimal dose of subcutaneous CAMPATH when used in combination with rituximab for patients with relapsing or refractory, low-grade or follicular, CD-20-positive, B-Cell non-Hodgkin's Lymphoma. Safety will be the primary objective of phase I, while the primary objective of phase II will be to determine overall response.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective in treating non-Hodgkin's lymphoma. PURPOSE: Randomized phase II/III trial to compare the effectiveness of combination chemotherapy with or without etoposide in treating older patients who have non-Hodgkin's lymphoma that has not been previously treated.

MiRNAs are noncoding RNAs (ncRNAs) that drive post-transcriptional negative regulation of gene expression by promoting the degradation or translational blockade of their target mRNAs. MiRNAs are 21-24-nucleotide-long RNA molecules that are processed from longer RNA precursors (pri-miRNAs) , and either the 5' or the 3' strand of the mature miRNA duplex is loaded into the Argonaute (AGO) family of proteins to form a miRNA-induced silencing complex (miRISC) When bound to AGO proteins, mature miRNAs destabilize or inhibit the translation of partially complementary target mRNAsMiRNA-124 has been shown to be a tumor suppressor, and a decrease in its expression level is typical of tumors of various localization, but there is no evidence of the role of miRNA-124 in the development of NHL . There are a number of studies reflecting the involvement of miRNA-124 in hematopoiesis. Liu et al. showed that miRNA-124 regulates Tip110 that is involved in the differentiation of hematopoietic stem cellsThe let-7 family has been shown to influence the pathogenesis of a variety of hematological malignancies through the changing expression of a number of oncogenic pathways, particularly those related with MYC and that might affect hematopoietic carcinogenesis through the modulation of inflammatory pathways

The present project aims at evaluating the capacity of MSC to improve one-year overall survival of patients transplanted with HLA-mismatched PBSC from related or unrelated donors after non-myeloablative conditioning. Co-infusion of MSC has been shown to facilitate engraftment of hematopoietic stem cell (HSC) in an immunodeficient mouse model. In addition, it has been shown that infusion of third party MSC in HSC transplantation could be successfully used as treatment for grade II-IV steroid-refractory acute graft versus host disease. One hundred and twenty patients with HLA-mismatched donors will be included over 6 years at multiple centers across Belgium through the transplant committee of the Belgian Hematological Society. The conditioning regimen will consist of fludarabine and 2 Gy TBI, followed by the infusion of donor HSC. Patients will be randomized 1/1 in double-blind fashion to receive or not MSC (1.5-.3.0 x106/kg) from third-party (either haploidentical family members or unrelated volunteer) donors on day 0. Postgrafting immunosuppression will combine tacrolimus and MMF. Except for the collection, expansion and infusion of MSC, the clinical management of the patient will not differ from that of routine NM-HCT.

The purpose of this study is to determine the feasibility of treating relapsed follicular lymphoma with a combination of Bexxar and External Beam Radiotherapy (EBRT). Patients will receive EBRT (20 Gy in 10 fractions) followed by Bexxar.

Phase II study of rituximab plus MG4101 in patients with relapsed or refractory indolent CD20-positive non-Hodgkin lymphoma (NHL) Investigator-Initiated Trials

This study will collect tumor samples from people with cancers of the blood, bone marrow, or lymph glands for laboratory study of the biology of these conditions. Such studies contribute to a better understanding of cancer biology and to the development of new treatments. Planned studies include: Examination of individual cancer cells and to search for differences compared to other types of cancer and normal cells Examination of the chromosomes and genes in cancer cells and to search for differences compared to other types of cancer and normal cells Development of sensitive methods to detect small amounts of cancer that remain after treatment Search for new cancer proteins that might serve as targets for treatment Investigation of methods to develop cancer vaccines. Patients from >= 1 to 75 years of age with acute lymphocytic leukemia, acute myelogenous leukemia, myelodysplastic syndrome, chronic myelogenous leukemia, juvenile myelomonocytic leukemia, non-Hodgkin's lymphoma, Hodgkin's disease, and other hematologic malignancies may be eligible for this study. Blood or bone marrow samples will be collected when sampling is required for the patient's medical care. Cells from some individuals will be grown in test tubes, establishing cell lines or in animals, establishing xenograft models. (A xenograft is transplantation of cells of one species to another species.)

This study seeks to determine the maximum tolerated dose of bortezomib in combination with rituximab, ifosfamide, carboplatin, and etoposide for patients with relapsed or primary refractory aggressive B-Cell Non-Hodgkin's lymphoma (diffuse large B-cell, mantle cell, follicular grade III, transformed lymphoma). Subjects will be enrolled in cohorts of 3 at each bortezomib dose level, starting at 1 mg/m(2), and escalating to 1.3, 1.5, and 1.7 mg/m(2). Bortezomib will be given on days 1 (prior to rituximab) and 4, rituximab 375 mg/m(2)/day on days 2, 3, and 4 of a 21-day cycle. They will also receive filgrastim on days 6-13 or pegfilgrastim on day 6.

Lymphomas are a fairly common malignancy accounting for approximately half of all newly diagnosed hematological neoplasms, and they comprise the sixth most common group of malignancies worldwide in both men and women, With marked geographic variations and affecting more males than females within the age range of 1 to 85 years but peaking within the second decades of life (Oluwasola AO et al., 2011, Roman E et al., 2011 and Jemal A et al., 2010) . Lymphomas have traditionally been classified as either Hodgkin's lymphoma (HL) or non-Hodgkin's lymphoma (NHL) based on the presence or absence of the Reed-Sternberg (RS) cell on histology. (Fitzmaurice C et al., 2017). Non-Hodgkin's lymphoma (NHLs) comprise a wide class of lymphoid neoplasms that evolve from the clonal expansion of mature B, T and natural killer (NK) cells in different stages of development (Morton, L.M. et al., 2014 and Schmitz R et al., 2009). NHLs are the most prevalent hematopoietic neoplasms, accounting for approximately 4.3% of all cancer diagnoses (Sant, M. et al., 2010) , Of them, B cell NHL accounts for approximately 30% of all lymphoid neoplasms, followed by HL (8%) and T/NK neoplasms (5%) (Morton, L.M. et al., 2006). MicroRNAs (miRNAs) are a class of small, naturally occurring, noncoding and single-stranded RNA molecules (18, 22 nucleotides) that function as post-transcriptional regulators by directly cleaving target messenger RNA (mRNA) or translational repression (Bartel DP. Et al., 2004). The discovery of miRNA has exposed a new layer of gene expression regulation that affects many physiological and pathological processes of life (Lawrie CH. Et al., 2013). Many abnormal miRNA expression patterns are found in various human malignancies, and certain miRNAs play roles as oncogenes or tumor suppressors (Ling N et al., 2013). Certain miRNAs have been found to characterize various subtypes of NHL and have important roles in B-cell differentiation and lymphomagenesis (Zhang J et al., 2009, Malumbres R et al., 2009, Basso K et al., 2009 and Auer RL et al., 2011). Recently, many studies had shown that tumor cell-specific miRNAs were detectable in the plasma and serum of patients with cancer. Therefore, miRNAs may be served as good biomarkers for early detection, diagnosis, and follow up of patients with cancer (Cortez MA et al., 2012).

This study is for patients who have been treated before and either the treatment did not work or the lymphoma has come back.
