The Importance of Accurate Determination of ADCC Activity During Biosimilar Development

19th August 2015

Category: Biosimilars

Tags: ,

By: Stefan Termen, Technical Services Scientist,

Cells infected with enveloped viruses will express viral proteins on their cell membranes, and many cancer cells will express specific surface antigens. These proteins are recognized by antibodies of the humoral immune system as targets for Antibody-Dependent Cell-mediated Cytotoxicity (ADCC). In this process, effector cells of the immune system recognize the bound antibodies through their More

Cost and Time Effective Approach to Early Stage Biosimilar Development: A Case Study of Tocilizumab

By: Dr Terry Gray, Field Marketing Manager,

Introduction to Tocilizumab (Actemra) Tocilizumab (Actemra (US)/RoActemra (EU)) is a therapeutic monoclonal antibody that targets the Interleukin-6 receptor (IL-6R).  Interleukin-6 (IL-6) is a multifunctional cytokine which is central to the regulation of the immune and nervous systems.  This molecule has been linked to pathogenesis of several autoimmune diseases including rheumatoid arthritis (RA) due to aberrations More

Psoriatic Arthritis treatment attracts attention for Biosimilar development

By: Dr Daniel Galbraith, CSO,

Like waiting for a bus, there was no effective treatment for psoriatic arthritis then three came along. The literature has been awash with the new treatments; anti-TNF α drugs such as Enbrel and Humira. Janssens anti-IL-12/23 drug Stelara and now the new IL-17 blocker Secukinumab from Novartis. These drugs have clinically demonstrated to be effective More

Current Challenges and Opportunities in Cost Effective and Affordable Biosimilars

27th October 2014

By: Dr Daniel Galbraith, CSO,

Biosimilars challenge us in many ways but for me these issues can be divided into those for a scientist, those for the industry and those for the patient. In my job, as a CSO working in Contract Research Organization, I have found Biosimilars have forced us to better understand the biological aspects of these drugs. More

Testing for Human Cytomegalovirus

Tags: ,

By: Dr Daniel Galbraith, CSO,

Human cytomegaloviruses (and simian) are members of a virus family that are specifically identified by the biologics safety guidelines as a specific concern. Most recently the 2010 FDA guidelines for testing of vaccine cell substrate included a recommendation that if there is the possibility of contamination with Human and Simian cytomegalovirus then the in vitro More

Top 10 problems encountered in IND or BLA submissions

During the Well Characterised Biological Congress an FDA reviewer gave us an insight into some of the common problems encountered in IND or BLA submissions with a list of the Top 10 inadequacies. Number 1 – The lack of procedural details contained within the submission. What was clear was that the FDA requires a working SOP More

Prospect of plant based production methodologies for Trastuzumab (Herceptin)

8th October 2013

Tags: , ,

By: Dr Daniel Galbraith, CSO,

The production of Biosimilar Monoclonal Antibodies often follows the same or similar production methodologies to the innovator product, Chinese Hamster Ovary Cells being the most common method. However there is nothing in the current guidelines to prevent the use of other production systems for these products. In the paper published by Grohs et al., 2010 More

Leptospira contamination – How to manage risk

27th September 2012

Category: Biosafety

Tags: ,

By: Dr Daniel Galbraith, CSO,

Vaccines and Biologics are recognized to be at high risk of contamination by bacteria and viruses. Over many years the risks have been determined and these products are recognized to be among the safest on the market. In the past there have been a number of viral contamination events which have resulted in increased vigilance More

Anti-TNF-alpha Biosimilars Humira, Remicade and Enbrel

Tags: , , , ,

By: Dr Daniel Galbraith, CSO,

Anti Tumor Necrosis Factor (Anti-TNF) drugs, Humira (adalimumab), Remicade (infliximab) and Enbrel (etanercept) are perhaps the most successful of all biologics both with respect to their turnover and the number of patients treated with these drugs. All have been shown in clinical trials to help with improving the clinical outcome of Rheumatoid Arthritis (RA) but More

Bovine Virus Contaminationin Cell Banks used in Biopharmaceuticals and Vaccines

25th November 2011

Tags: ,

By: Dr Daniel Galbraith, CSO,

The risk of contamination of biopharmaceuticals and vaccines by Bovine viruses has been well recognized. Calf serum was, and in some instances still is, commonly used to supplement the growth media for cells used in production of many vaccines and some biologics. Although “serum-free” media is frequently used today the risk of exposure to bovine More
