Almost half of the participants had failed to respond to six or more AEDs.The participants were randomly divided into three groups and received either a low dose of everolimus, a high dose of everolimus or an identical-looking placebo.The results showed that in people who received a low dose of the drug, seizure frequency was reduced by more than 29%. This figure was nearly 40% in the high-dose group.Adverse side effects such as inflammation of the mouth and lips, diarrhoea, common cold, fever and upper respiratory tract infection occurred in 3% of subjects who received placebo and 14% of those who received a low dose or high dose of everolimus. Dr Franz notes that these figures are consistent with findings from previous everolimus trials.TSC is a genetic disease that causes malformations and tumours in the brain and other organs. It is estimated to affect approximately one million people around the world.Everolimus is a derivative of the drug sirolimus and works in a similar way by inhibiting a signalling complex called ‘mammalian target of rapamycin complex 1’ (mTORC1). There is evidence that this signalling pathway plays a role in both acquired forms of epilepsy and TSC.Author: Dr Özge ÖzkayaClick here to read about an ERUK-funded pilot study into TSC, led by Professor Alexander Hammers, at King’s College London.Click here for more articles about other treatments for epilepsy.
