Paladin Labs Inc. (TSX:PLB) and Somaxon Pharmaceuticals, Inc. (Nasdaq: SOMX) today announced that Paladin has filed a New Drug Submission (NDS) that has been accepted for review by Health Canada for Silenor
(doxepin) for the treatment and symptomatic relief of insomnia.
“We are pleased that Health Canada has accepted to review our submission for Canadian regulatory approval for Silenor
,” said Mark Beaudet, interim President and Chief Executive Officer of Paladin Labs Inc. “We believe that Silenor
can fill a significant unmet need in the Canadian insomnia market. To date, the Canadian prescription sleep aid market has consisted mainly of zopiclone, an older medication that, despite its limitations, has driven the market to exceed $87 million in 2011
, an increase of 10% vs. 2010.”
If approved, Silenor
could be the first and only prescription product approved for the treatment of insomnia in Canada that is not a controlled substance.
Paladin received rights to commercialize Silenor
in Canada, South America and Africa from Somaxon in June 2011. Under the collaboration agreements, there is no payment due to Somaxon from Paladin as a result of the NDS filing. Once Silenor
is commercialized in the licensed territories, Somaxon will be eligible to receive sales-based milestone payments of up to US$128.5 million as well as a tiered double-digit percentage of net sales.
is a low-dose (3 mg and 6 mg) oral tablet formulation of doxepin. If approved, Silenor
is expected to be the first and only non-controlled prescription sleep medication in Canada indicated for the treatment and symptomatic relief of insomnia characterized by difficulty in falling asleep, frequent nocturnal awakening and/or early morning awakenings.
