An update on TGN1412

In the last issue of ATLA, we assessed whether the existing methods for assessing the safety and efficacy of new candidate medicines was adequate for the testing of humanised therapeutic agents. We made specific reference to the failed TGN1412 first-in-man study that took place earlier this year. This paper was circulated to experts and those involved in the development or testing of TGN1412. More recently, the Focus on Alternatives group has made a submission to the Expert Working Group that is currently considering how such incidences can be avoided in the future. Here, we provide an update of the events relating to the TGN1412 clinical trial.
