Evotec expects the results from a second Phase II study in 135 elderly insomniacs to be available in October 2007.

Although certain aspects of insomnia are addressed by current treatments, there is no drug yet available which meets all the needs of insomnia patients.

About EVT 201

EVT 201 is a partial positive allosteric modulator (pPAM) of the GABAA receptor complex. Acting on GABAA receptors it addresses the gold standard mechanism for insomnia with more than 90% of current insomnia drugs using this mechanism. Importantly, however, its close to ideal half life of 3 to 4 hours and its partial agonist activity gives EVT 201 a differentiated preclinical profile and mechanism of action.

The headline results of the first Phase II study with EVT 201 were very positive in terms of all aspects of the problems faced by insomniacs, i.e. sleep onset and sleep maintenance and yet the patients didn't feel any drug hang-over effects after waking in the morning. Furthermore, in two previous Phase I/II proof-of-principle studies in subjects with induced insomnia, EVT 201 significantly reduced Wake After Sleep Onset (WASO) while significantly increasing the Total Sleep Time (TST) and quality of sleep with no subjective residual effects. The studies were conducted in a sleep laboratory setting using the traffic noise model of insomnia in healthy male volunteers. In this setting an average of 52 decibels of recorded traffic noise is played throughout the night thereby provoking insomnia. This model has been used to evaluate several insomnia treatments currently in development and on the market. EVT 201 showed no tolerance/dependence liabilities in pre-clinical studies and no interaction with alcohol.
