The anti-CD20 monoclonal antibody rituximab (MabThera® /Rituxan® ) has been proven to improve outcomes in a range of B-cell malignancies. Initially developed as a formulation for intravenous infusion, administration times for rituximab can be prolonged and associated with infusion-related reactions, prompting a combined clinical development program investigating subcutaneous delivery in combination with recombinant human hyaluronidase. As this program comes to fruition, this article reviews the evidence demonstrating subcutaneous rituximab to have noninferior pharmacokinetics when delivered at a fixed-dose as well as equivalent clinical outcomes in the treatment of follicular lymphoma, chronic lymphocytic leukemia and diffuse large B-cell lymphoma...

ABO-incompatible (ABOi) kidney transplantation has become an established strategy to increase the number of available living donors. At our center, the conditioning protocol for ABOi patients is based on anti-A/B antibody removal and depletion of B cells with the anti-CD20 mAb rituximab (Mabthera®). It is known that even low amounts of remaining rituximab in serum of patients results in false positive B cell cross match results, masking detection of potentially harmful donor human leukocyte antigen (HLA) specific antibodies...

Rituximab (MabThera® /Rituxan® ), a chimeric murine/human monoclonal antibody that binds specifically to the transmembrane antigen CD20, was the first therapeutic antibody to enter clinical practice for the treatment of cancer. As monotherapy and in combination with chemotherapy, rituximab has been shown to prolong progression-free survival and, in some indications overall survival, in patients with various B-cell malignancies, while having a well-established and manageable safety profile and a wide therapeutic window...

AIMS: Production and release of injectable drug solutions are highly regulated since the administration of injectables bypasses natural body barriers. The sterility test is the last opportunity of product quality assessment. However, sterility is currently assessed by visual inspection (VI) that is time consuming and somewhat subjective. Therefore, we assessed isothermal microcalorimetry (IMC) as a replacement for the VI of the filtration based state-of-the-art sterility control. METHODS AND RESULTS: We used ATCC strains and house isolates to artificially contaminate frequently produced monoclonal antibodies (Avastin, Mabthera, Herceptin)...

BACKGROUND: The conventional frontline therapy for fit patients with chronic lymphocytic leukaemia (CLL) is fludarabine, cyclophosphamide and rituximab (FCR). Rituximab (Mabthera® , Roche Products Ltd) targets the CD20 antigen, which is expressed at low levels in CLL. The standard dose of rituximab in CLL (375 mg/m2 in cycle 1 and 500 mg/m2 in cycles 2-6) was selected based on toxicity data only. Small doses of rituximab (as low as 20 mg) have biological activity in CLL, with an immediate reduction in circulating CLL cells and down-regulation of CD20...

Traditional antibody dependent cellular cytotoxicity (ADCC) assays use donor derived natural killer (NK) or peripheral blood mononuclear cells, but donor genetic variability and the technically challenging nature of the assay means that alternative in vitro assay formats are required. We explored the utility of two reporter gene cell lines, the J2 and J9, as surrogate effector cells for ADCC assays. Both express the ADCC relevant Fcγ receptor CD16, crosslinking of which leads to firefly luciferase expression...

INTRODUCTION: Additional risk minimisation measures (aRMMs) for medicinal products are necessary to address specific important safety issues which may not be practically achieved through routine risk management measures alone. The implementation and determination of effectiveness for aRMMs can be a challenge as it involves multiple stakeholders. It is therefore important to have concise objectives to avoid undue burden on patients, healthcare professionals and the healthcare system. AIM: The aim of this study was to examine how aRMMs are implemented and how effectiveness is assessed in the European Union (EU) using practical examples from Roche Products Limited in the United Kingdom (UK) (referred to as the 'Company')...

BACKGROUND: A subcutaneous (SC) formulation of rituximab (MabThera(®)/Rituxan(®)) has been developed that could reduce administration time and improve patient satisfaction with treatment. The Rituximab Administration Satisfaction Questionnaire (RASQ) was created to assess patients' perceptions and satisfaction with rituximab SC (RASQ-SC) or rituximab intravenous (RASQ-IV). We assessed the content validity and psychometric properties of RASQ in patients with non-Hodgkin lymphoma. METHODS: Face and content validity of RASQ-SC and RASQ-IV were qualitatively assessed using 60-minute combined concept elicitation and cognitive debriefing interviews...

PURPOSE: Rituximab (MabThera™, Roche) is a chimeric IgG1 monoclonal antibody targeting the CD20 surface antigen on normal and neoplastic B cells. It revolutionized the treatment of non-Hodgkin's lymphoma with superior progression-free and overall survival. However, its prohibitively high cost makes it inaccessible to majority of patients in developing countries. Reditux™ (Dr. Reddy's Laboratories, India), a biosimilar, was introduced in India in 2007 at nearly half the price of the innovator...

Waldenströms macroglobulinemia which was manifested by muscle pain and anemia. The female patient had suffered from back pain for about 3 years before she came to our clinic. In the last year pain in the muscles of the upper and lower extremities developed in addition to back pain. This led to the suspicion of polymyositis. However this was not confirmed by a special examination. The patient was diagnosed with clearly established infiltration of lympho-plasmacytic lymphoma and 10.8 g/l of type IgM monoclonal immunoglobulin in the bone marrow...

Granulomatosis with polyangiitis (Wegener's granulomatosis) and microscopic polyangiitis are two types of rapidly fatal necrotizing vasculitis. The standard induction therapy consists of cyclophosphamide (an immunosuppressant) plus a corticosteroid. This treatment significantly prolongs survival but has burdensome adverse effects. After an induction phase lasting 3 to 6 months, cyclophosphamide is replaced by another immunosuppressant such as azathioprine for 2 to 5 years in order to prevent relapse. There is no consensus on an alternative treatment for patients who cannot receive cyclophosphamide...

In response to the successful use of monoclonal antibodies (mAbs) in the treatment of various diseases, systems for expressing recombinant mAbs using transgenic animals or plants have been widely developed. The silkworm (Bombyx mori) is a highly domesticated insect that has recently been used for the production of recombinant proteins. Because of their cost-effective breeding and relatively easy production scale-up, transgenic silkworms show great promise as a novel production system for mAbs. In this study, we established a transgenic silkworm stably expressing a human-mouse chimeric anti-CD20 mAb having the same amino acid sequence as rituximab, and compared its characteristics with rituximab produced by Chinese hamster ovary (CHO) cells (MabThera®)...
