Efficacy and safety of agomelatine (10 or 25 mg/day) in non-depressed out-patients with generalized anxiety disorder: A 12-week, double-blind, placebo-controlled study.

Agomelatine is efficacious in reducing symptoms and preventing relapse in placebo-controlled trials in generalised anxiety disorder (GAD). Nevertheless, fixed dose studies of agomelatine in GAD have not been undertaken. To determine the minimally effective optimal dose of agomelatine in GAD, the efficacy of two doses of agomelatine (10 and 25mg/day) was investigated in a 12-week, placebo-controlled, double-blind, international study in patients with a primary diagnosis of GAD.

Agomelatine in generalized anxiety disorder: an active comparator and placebo-controlled study.

Background: Agomelatine was efficacious in reducing symptoms in a short-term placebo-controlled trial in generalized anxiety disorder (GAD) and in preventing relapse in a longer term placebo-controlled study. An additional short-term placebo-controlled study is required by regulatory agencies to confirm the efficacy of agomelatine in GAD.

Method: This 12-week, placebo-controlled, double-blind, randomized, parallel group, international, multicenter study was designed to confirm the efficacy of agomelatine 25-50 mg/d in the treatment of patients with a primary DSM-IV-TR diagnosis of GAD.

Activation of mGlu2/3 receptors as a new approach to treat schizophrenia: a randomized Phase 2 clinical trial.

Schizophrenia is a chronic, complex and heterogeneous mental disorder, with pathological features of disrupted neuronal excitability and plasticity within limbic structures of the brain. These pathological features manifest behaviorally as positive symptoms (including hallucinations, delusions and thought disorder), negative symptoms (such as social withdrawal, apathy and emotional blunting) and other psychopathological symptoms (such as psychomotor retardation, lack of insight, poor attention and impulse control). Altered glutamate neurotransmission has for decades been linked to schizophrenia, but all commonly prescribed antipsychotics act on dopamine receptors.
