Control Testing of Biological Medicines
Biological substances used in healthcare
include viral and bacterial vaccines, products derived from human
blood, monoclonal antibodies, hormones, cytokines and growth
factors. They have made a major and increasingly important
contribution to medicine and public health and have brought radical
improvements in the prevention and treatment of disease throughout
the world..
Biological substances used in healthcare include bacterial and
viral vaccines against diseases such as diphtheria, whooping-cough,
meningitis, poliomyelitis, influenza, hepatitis, measles, mumps and
rubella, and therapeutic products derived from human blood such as
clotting factors and immunoglobulins. In addition to these
traditional products, an increasing number of new ’high-tech’
biological medicines are being produced by the latest techniques of
genetics and molecular biology.
Biological medicines and vaccines are usually very complex
materials. In order to ensure that these products are both safe and
effective it is necessary to thoroughly evaluate their quality and
biological activity. For many biologicals, there is a legal
requirement that each batch is examined and approved, independently
from the manufacturers, before release onto the market. Such
’control’ or ’batch release’ testing involves the review of
manufacturing documentation and laboratory tests on the product
itself. As the UK’s Official Medicines Control Laboratory (OMCL),
NIBSC performs this function through the EU Official Control
Authority Batch Release (OCABR) testing process. Other medicines
control activities include assessment of new products, non-EU batch
release, and product monitoring of released products. Products are
also evaluated under the Centrally Approved Products (CAP) testing
scheme organised by the European Directorate for the Quality of
Medicines and Healthcare. Control work conducted by NIBSC is
carried out in compliance to ISO/IEC 17025, with independent
accreditation by UKAS.
NIBSC works closely with the EU OMCL network and regulatory
authorities regarding development of policies and processes for
batch release assessment and related activities. Associated
research activities are conducted to underpin control work. These
allow rapid responses to unexpected safety and/or efficacy problems
which can sometimes occur with biological medicines.
Our aim is to maintain our position as a leading,
influential and respected member of the European OMCL network,
carrying out batch release testing of products in areas of major
public health impact.
