Full description

Lu AA21004 was discovered by H. Lundbeck A/S, and is under co-development by H. Lundbeck A/S and Takeda for the treatment of major depressive disorder and general anxiety disorder. Major depressive disorder (MDD) is a chronic, recurring disease with considerable morbidity in the general population. The estimated lifetime prevalence of major depression in the adult population is 5 to 25%, with approximately 2-fold higher prevalence in women than in men. The hallmark of the disease is a depressed mood, with additional symptoms including sleep disturbances, psychomotor agitation or retardation, sexual dysfunction, weight loss, concentration difficulties and delusional ideas. In addition to direct ill effects, MDD causes suicide or job loss and exerts indirect influence on social economy. This study will assess the efficacy and the safety of Lu AA21004. This study consists of a 1-week screening period, an 8-week double-blind treatment period, 4-week safety follow-up.The duration of the study is 13 weeks in total. Blood samples will be collected from participants, and a safety follow-up contact (visit or phone call) will be made 4 weeks after completion of the 8-week double-blind treatment period. Subjects who complete the 8-week double-blind treatment period can successively enter a long-term extension study (Lu AA21004/OCT-001; NCT01395147; hereinafter, OCT-001), if they meet all inclusion criteria and none of exclusion criteria of the OCT-001 study and are willing to participate in the OCT-001 study. Subjects who will enter the OCT-001 will not be requested to safety follow-up after completion of the 8-week double-blind treatment period.
