The MHRA has today released its interim report into the adverse incidents which occurred on 13th March 2006 during the clinical trials of TGN1412 (see report below).

It has found no evidence to suggest that there was any problem with the manufacturing of the product which was given to the trial volunteers – it appears not to have been contaminated, or to have contained anything other than the correct ingredients. Neither have we found anything in the way the trial was run which contributed to the adverse reactions experienced by the volunteers – it was run according to the agreed protocol, and the correct dose of the product was given to the patients.

“There are still further tests planned and until these are complete we cannot be firm about our conclusions.  However, if these findings were to be confirmed, it would indicate that this product showed a pharmacological effect in man which was not seen in pre-clinical tests in animals at much higher doses.  The Secretary of State for Health has therefore agreed to establish a group of leading international experts in the field to examine the issue further. The Group will need to review the evidence from the TGN1412 case and consider what necessary changes to clinical trials may be required”, says MHRA Chief Executive Professor Kent Woods.
