New Potential Therapeutic Approach for the Treatment of B-Cell Malignancies Using Chlorambucil/Hydroxychloroquine-Loaded Anti-CD20 Nanoparticles
2013
Current B-cell disorder treatments take advantage of dose-intensive chemotherapy regimens and immunotherapy via use of monoclonal antibodies. Unfortunately, they may lead to insufficient tumor distribution of therapeutic agents, and often cause adverse effects on patients. In this contribution, we propose a novel therapeutic approach in which relatively high doses of Hydroxychloroquine and Chlorambucil were loaded into biodegradable nanoparticles coated with an anti-CD20 antibody. We demonstrate their ability to effectively target and internalize in tumor B-cells. Moreover, these nanoparticles were able to kill not only p53 mutated/deleted lymphoma cell lines expressing a low amount of CD20…
Unraveling the T-B tangle in anti-CD20 multiple sclerosis therapy.
2019
Significance Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. CD8+ T cells have been strongly implicated in MS pathogenesis, but it is unclear whether myelin is a CD8+ T cell autoantigenic target in MS. This study demonstrated that while myelin-specific CD8+ T cells are present at similar frequencies in untreated MS patients and healthy subjects, the proportion of memory and CD20-expressing myelin-specific CD8+ T cells was increased in MS patients, suggesting prior antigen encounter. This activated phenotype was reversible as the memory and CD20-expressing populations of certain myelin-specific CD8+ T cells were reduced following anti-CD20 trea…
Efficacy and safety of rituximab with and without methotrexate in the treatment of rheumatoid arthritis patients: Results from the GISEA register
2014
Abstract Introduction Rituximab (RTX) is a monoclonal anti-CD20 antibody approved for the treatment of rheumatoid arthritis (RA) in association with methotrexate (MTX). Objectives To evaluate the efficacy and safety of RTX–MTX combination therapy compared with RTX alone in the treatment of RA. Methods We analyzed data from a prospective cohort study, the Italian biologic register GISEA, to investigate the efficacy and safety of rituximab. Moreover, the adverse events (AE) and the causes of discontinuation therapy were analyzed. Results We identified 338 RA patients, 162 treated with RTX and 176 with RTX–MTX. After 52 and 104 weeks of therapy the disease activity score in 28 joints and the H…
