Targeting B cells in relapsing–remitting multiple sclerosis: from pathophysiology to optimal clinical management
2017
Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease that is caused by an autoimmune response against central nervous system (CNS) structures. Traditionally considered a T-cell-mediated disorder, the contribution of B cells to the pathogenesis of MS has long been debated. Based on recent promising clinical results from CD20-depleting strategies by three therapeutic monoclonal antibodies in clinical phase II and III trials (rituximab, ocrelizumab and ofatumumab), targeting B cells in MS is currently attracting growing interest among basic researchers and clinicians. Many questions about the role of B and plasma cells in MS remain still unanswered, ranging from the role of…
BIOM-08. DNA METHYLATION-BASED SUBGROUPING PREDICTS SURVIVAL BENEFIT FROM LOMUSTINE/TEMOZOLOMID COMBINATION THERAPY IN MGMT PROMOTOR-METHYLATED GLIOB…

Abstract BACKGROUND The CeTeG/NOA-09 trial showed that lomustine/temozolomide chemotherapy prolongs survival for newly diagnosed MGMT-methylated glioblastoma patients. Previous reports on temozolomide monotherapy suggested, that the survival benefit of temozolomide in MGMT-methylated tumors may be restricted to the RTK II methylation subgroup and absent in RTK I and MES subgroups. To identify patients with a particularly strong benefit from CCNU/TMZ, we explored the association of methylation subgroups with outcome after lomustine/temozolomide therapy. METHODS All patients from the CeTeG/NOA-09 trial with sufficiently available tumor tissue (n = 98) underwent 850K methylation array analysis…

There is an urgent need for more effective therapies in glioblastoma (GBM). Data from the single arm UKT-03 trial (Glas et al., J Clin Oncol 27, 1257, 2009) suggested that combined lomustine/temozolomide (CCNU/TMZ) therapy might have superior activity in MGMT-methylated GBM. The phase III CeTeG/NOA-09 trial was set up to test this hypothesis in a randomized setting. Patients with MGMT-methylated GBM were randomized (1:1) for standard therapy with daily TMZ (75 mg/m2) during local radiotherapy (RT, 30 x 2 Gy) followed by 6 courses of TMZ (150–200 mg/m2/day for 5 days q4w) or experimental therapy with CCNU/TMZ in addition to local RT. Six 6-week courses of CCNU/TMZ (CCNU 100 mg/m2 d1, TMZ 100…

Summary Background There is an urgent need for more effective therapies for glioblastoma. Data from a previous unrandomised phase 2 trial suggested that lomustine-temozolomide plus radiotherapy might be superior to temozolomide chemoradiotherapy in newly diagnosed glioblastoma with methylation of the MGMT promoter. In the CeTeG/NOA-09 trial, we aimed to further investigate the effect of lomustine-temozolomide therapy in the setting of a randomised phase 3 trial. Methods In this open-label, randomised, phase 3 trial, we enrolled patients from 17 German university hospitals who were aged 18–70 years, with newly diagnosed glioblastoma with methylated MGMT promoter, and a Karnofsky Performance …
