Filter by:MiRNAs are small (~19-25 nucleotides) non-coding RNA molecules that bind to mRNA in a sequence-specific manner. MiRNAs regulate gene expression at the post-transcriptional level. MiRNAs regulate critical cell processes such as metabolism, apoptosis, development, cell cycle, hematopoietic differentiation and have been implicated in the development and progression of several types of cancers, including hematological malignancies. Over-expression, amplification and/or deletion of miRNAs and miRNA-mediated modification of epigenetic silencing can all lead to oncogenic pathways. Hematologic cancers, which are caused by the malignant transformation of bone marrow cells and the lymphatic system, are usually divided into three major clusters: leukemia, lymphoma, and multiple myeloma. To date, some of the hematological malignancies are very aggressive that early diagnosis is essential for improving prognosis and increasing survival rates. However, current diagnostic methods have various limitations, such as insufficient sensitivity, specificity, it is also time-consuming, costly, and requires a high level of expertise, which limits its application in clinical contexts. Thus, development of new biomarkers for the early detection and relapse of hematological malignancies is desirable. Some of the innate properties of miRNAs make them highly attractive as potential biomarkers. MiRNAs can be readily detected in small volume samples using specific and sensitive quantitative real-time PCR; they have been isolated from most body fluids, including serum, plasma, urine, saliva, tears and semen and are known to circulate in a highly stable, cell-free form. They are highly conserved between species, allowing the use of animal models of disease for pre-clinical studies. Furthermore, tumor cells have been shown to release miRNAs into the circulation and profiles of miRNAs are altered in the plasma and/or serum of patients with cancer. A growing number of publications confirm that miRNAs can be a useful biomarker for hematological malignancies diagnosis and progression.
The primary objective of the study is to assess the efficiency of SCT400 plus CHOP versus Rituximab plus CHOP in untreated CD20-positive DLBCL Patients. The secondary objective of the study is to evaluate the safety of SCT400 plus CHOP, as well as the presence of human anti-chimeric antibodies (HACA).
Forty percent of patients with diffuse large B cell lymphoma (DLBCL) have primary refractory or relapsed disease (R/R). For these fit patients, standard treatment in second line therapy is high dose therapy with autologous stem cell transplantation (ASCT). In 48% of DLBCL no ASCT is possible due to progressive disease. For these patients or ineligible to transplantation patients, salvage therapy is often rituximab-gemcitabine-oxaliplatine regimen with an overall response rate (ORR) about 50%. Bendamustine in combination with rituximab, used as a single agent in the setting of R/R DLBCL patients, have shown an ORR of 62.7% and 45.8% with a good safety profile. Bendamustine and cytarabine (BAC) showed high synergy in inducing cell death in mantle cell lymphoma and DLBCL cell lines. In a recent phase II study, the combination of cytarabine with Rituximab and Bendamustine (R-BAC) in patients with mantle cell lymphoma who were previously untreated, refractory or relapsed was evaluated. The efficacy and safety of the R-BAC association will be evaluated in this phase II trial enrolling 78 patients with relapsed or refractory DLBCL.
NM-IL-12 is being evaluated as an immunotherapeutic with concomitant hematopoietic regenerating properties for treatment of relapsed/refractory DLBCL, an aggressive type of B-cell non-Hodgkin's lymphoma (NHL). Determination of the maximum tolerated dose (MTD) for NM-IL-12 is not planned in this study, rather, a pre-defined dose of 150 ng/kg will be explored; this dose is based on two safety and tolerability studies of NM-IL-12 in healthy volunteers.
