WASHINGTON, Jan. 31, 2013

WASHINGTON, Jan. 31, 2013 /PRNewswire/ --Vanda Pharmaceuticals Inc. (NASDAQ:
VNDA) today 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.


MAGELLAN was a proof of concept, two arm (tasimelteon 20mg and placebo),
8-week, double-masked, randomized, phase IIb/III clinical study in patients
with MDD. The study enrolled 507 patients in 43 sites in the U.S. The
primary endpoint of the study was the change from baseline in the Hamilton
Depression Scale (HAMD-17) at week 8.

About Tasimelteon

Tasimelteon is a circadian regulator in development for the treatment of
Non-24. Tasimelteon is a melatonin agonist of the human MT[1] and MT[2]
receptors, with greater specificity for MT[2].^ Tasimelteon's ability to
reset the master body clock in the suprachiasmatic nucleus (SCN), located in
the hypothalamus, results in the entrainment of the body's melatonin and
cortisol rhythms to align to the 24-hour day-night cycle. Tasimelteon is
currently in Phase III development for Non-24. A New Drug Application, is
expected to be submitted to the U.S. Food and Drug Administration in mid-2013
for Non-24.
