Takeda and Lundbeck jointly announced the submission of a New Drug Application (NDA) to the FDA for the investigational agent vortioxetine (Lu AA21004) for the treatment of major depressive disorder (MDD) in adult patients.
The NDA includes data from six short-term placebo controlled studies, including one dedicated study in the elderly, which have been conducted in regions throughout the world and support statistically significant efficacy of vortioxetine in a dose range of 5–20mg per day. Efficacy of vortioxetine was also demonstrated in a long-term relapse-prevention study in MDD. The vortioxetine global clinical development program included more than 7,500 individuals exposed to the drug.
Vortioxetine is thought to work through a combination of two mechanisms of action: receptor activity modulations and reuptake inhibition. In vitro studies indicate that vortioxetine is a 5-HT3 and 5-HT7 receptor antagonist, 5-HT1B receptor partial agonist, 5-HT1A receptor agonist and inhibitor of the serotonin transporter (SERT). In vivo non-clinical studies have demonstrated that vortioxetine enhances levels of the neurotransmitters serotonin, noradrenaline, dopamine, acetylcholine and histamine in specific areas of the brain.
