Successful completion of first-in-man study with EVT 103.
• Positive feedback from the FDA to initiate Phase II with EVT 101.

Evotec AG today announced two positive aspects that strengthen its integrated product development intreatment-resistant de-pression in its strategic alliance with Roche.

Evotec AG completed the clinical part of the first Phase I study with its NR2B-selective NMDA receptor antagonist EVT 103. EVT 103 is a small molecule drug candidate intended for oral use in conditions such as treat-ment-resistant depression, but potentially also other CNS indications.

The first-in-human Phase I study was a double-blind, placebo-controlled, randomised ascending dose study in 72 healthy young male subjects. The endpoints of the study were safety, tolerability and pharmacokinetic profile after oral single and multiple dose administration. In addition, the effect of food on the pharmacokinetics of EVT 103 was investigated. The compound was safe and very well tolerated, with excellent bioavailability and only a minimal effect of food on the kinetic profile.

In addition, for its NMDA receptor antagonist EVT 101, which is the lead compound in the strategic alliance with Roche in treatment-resistant de-pression, the FDA has allowed Evotec to proceed with the initiation of a Proof-of-Concept study. The study will start recruiting patients in Q2.

We are glad that we received positive feedback from the FDA regarding the toxicology and safety aspects of the planned Proof-of-Concept study with EVT 101. In addition, the Phase I results of EVT 103 now make this a very strong programme for a clinical product development in treatment-resistant depression”, said Dr Werner Lanthaler, Chief Executive Officer of Evotec.

About NMDA Receptors
NMDA receptors are involved in the pathology of depression. NR2B-selective antagonists bind preferentially to the activated form of the NMDA receptor containing the NR2B subunit and allosterically modulate, in an activity-dependent manner, channel activity by inhibiting channel opening probability. They show advantages over non-selective NMDA antagonists due to greater separation of efficacy from side effects.

About Roche & Evotec Development Alliance
Evotec has entered into an alliance with Roche with the potential value of this transaction exceeding USD 300 million. Evotec is responsible for conducting Phase II clinical development of EVT 101 in patients with treatment-resistant depression, a compound originally discovered by Roche and developed from discovery stages through clinical studies by Evotec. Within this alliance, Evotec has conducted Phase I safety and tolerability studies for EVT 103, a next generation compound to EVT 101. Roche fully funds these development programmes.

About Treatment-Resistant Depression
More than 120 million people are estimated to suffer from depression globally. According to the National Institute for Mental Health, some of the symptoms include persistent sad, anxious or “empty” mood, feelings of hopelessness or pessimism, feelings of guilt, worthlessness or helplessness, or loss of interest or pleasure in hobbies and activities that were once enjoyed.
According to European Neuropsychopharmacology (D. Souery, 1999) it has been recognised that about one third of patients treated for major depression disorder do not respond satisfactorily to the first antidepressant pharmacotherapy. Treatment-resistant depression is a term used in clinical psychiatry to describe cases of major depressive disorder that do not respond to adequate courses of at least two antidepressants. There is currently no approved monotherapy for treatment-resistant depression, and there are few new mechanisms in clinical development for depression.
