In the recently completed phase III clinical trials, Lu AA21004 was tested in doses of 2.5, 5 and 10 mg. Results from two studies, which included the lower dosages, 2.5 and 5 mg, did not reach significance across studies when compared with placebo.
A third trial demonstrated mixed results, with the 2.5 mg dose not reaching statistical significance compared to placebo, and the 5 and 10 mg doses showing separation from placebo, although not in all analyses. These results also suggest that a higher dose may be more efficacious.
In all of these trials, Lu AA21004 was well tolerated and confirmed the previously observed favourable safety profile.
As a result, the most appropriate dose of Lu AA21004 needs to be established. It is anticipated that this work will postpone submission of the new drug application (NDA) in the US with approximately 18-24 months. Lundbeck and Takeda will continue to work with the U.S. Food and Drug Administration (FDA) and other regulatory agencies on the clinical development program and submission plans.
Lu AA21004 is also in phase III development for generalised anxiety disorder (GAD).
About depression
Depression is a very common, debilitating illness affecting around 121 million people worldwide. Depression is not at all recognised by society as the serious disorder it actually is. The symptoms of depression can be chronic or recurrent, and impact patients both mentally and physically. Depression has a significant impact on patient quality of life and imposes a considerable burden on society, yet it is still under-recognised and undertreated with less than 25 percent of those affected having access to effective treatment.
Symptoms include feelings of sadness, anxiety, loss of interest in activities, decreased energy, impaired sleep, impaired concentration, hopelessness, guilt, persistent physical symptoms such as pain and digestive disorders, and in more severe cases, suicidal thoughts and suicide attempts.
