Top-line results from Vanda's tasimelteon Phase IIb/III study on major depressive disorder

We know that, Tasimelteon (BMS-214,778) is a drug which is under development for the treatment of insomnia and other sleep disorders. It is a selective agonist for the melatonin receptors MT1 and MT2 in the suprachiasmatic nucleus of the brain, similar to older drugs such as ramelteon. It has been through Phase III trials successfully and was shown to improve both onset and maintenance of sleep, with few side effects.

A year-long (2011-2012) study at Harvard is testing the use of tasimelteon in blind subjects with non-24-hour sleep-wake disorder.
Now Vanda Pharmaceuticals Inc. (NASDAQ: VNDA),  announced top-line results of the Phase IIb/III clinical study (MAGELLAN) in Major Depressive Disorder (MDD), investigating the efficacy and safety of tasimelteon as a monotherapy in the treatment of patients with MDD.  The clinical study did not meet the primary endpoint of change from baseline in the Hamilton Depression Scale (HAMD-17) after 8 weeks of treatment as compared to placebo.  Both tasimelteon and placebo treated patients had an approximately 40% reduction of their MDD symptoms from baseline.  Tasimelteon was shown to be safe and well-tolerated, consistent with observations in prior studies.  Given these current proof of concept clinical study results, Vanda has decided to discontinue all activities in this indication.

"These results are disappointing, as there is still a significant unmet medical need for patients with Major Depression," said Mihael H. Polymeropoulos , M.D., President and CEO of Vanda.  "Tasimelteon's application in the treatment of blind individuals with Non-24 remains our top priority as we pursue our planned NDA submission this year."     

Vanda has recently reported positive results in two phase III clinical studies of tasimelteon in Non-24-Hour Disorder (Non-24) and plans to submit a New Drug Application to the U.S. Food and Drug Administration in mid-2013......

FDA Acceptance of New Drug Application for Vilazodone for the Treatment of Major Depressive Disorder..

Vilazodone(see structure) is an antidepressant which is currently under  development by Clinical Data for the treatment of major depressive disorder, and as of 2009 has completed two phase III clinical trials with positive results. An NDA was submitted on March 23rd, 2010 in the United States and is currently pending approval by the FDA which, if approved, will likely precede vilazodone's availability on the market by the end of 2010.

Now the company claims that FDA has accepted for filing the Company's New Drug Application (NDA) for vilazodone for the treatment of major depressive disorder (MDD).

Vilazodone is a dual-acting potent and selective serotonin reuptake inhibitor and a 5-HT1A receptor partial agonist. The NDA will be subject to a standard review. 

The acceptance of the NDA for review by the FDA is another positive step toward our goal of bringing vilazodone to market, and if approved, vilazodone will offer a novel treatment to the millions of people suffering from depression”  says Carol R. Reed, M.D., Executive Vice President and Chief Medical Officer of Clinical Data.....
