Investigations into adverse incidents during clinical trials of TGN1412
"An unpredicted biological action of the drug in humans is the most likely cause of the adverse reactions in the trial participants. Monoclonal antibodies are a relatively new type of biological drug although there are a number of them already licensed and in use. However, TGN1412 is a new class of monoclonal antibody which has a stimulatory mode of action affecting certain types of cell in the immune system. In this case the resulting activity seen in humans was not predicted from apparently adequate pre-clinical testing.
"This is a complex scientific issue which raises important scientific and medical questions about the potential risks associated with this type of drug and how to make the transition from pre-clinical testing to trials in humans."
