AEterna Zentaris Inc. (USA) (AEZS) Stock Fires Up to the Roof; Here’s Why

AEterna Zentaris Inc. (USA)(NASDAQ:AEZS) investors are busy throwing a party today following the news that tiny drug maker has sold its U.S. and Canadian rights to MACRILEN™ (macimorelin), a drug designed to evaluate adults for growth hormone deficiency, to Strongbridge Biopharma (NASDAQ:SBBP).

Under the terms of the license and assignment agreement, Strongbridge will make an upfront payment of $24 million to Aeterna Zentaris within five days of the effective date of the agreement.  Strongbridge has agreed to pay tiered royalties in the mid-to-high teens as a percentage of net sales as well as milestone payments upon FDA approval of a pediatric indication and the achievement of pre-determined sales levels. The license and assignment agreement also provides Strongbridge with an exclusive license to manufacture and commercialize MACRILEN in the U.S. and Canada. Aeterna Zentaris will remain responsible for a pediatric development program to support regulatory submission for approval with Strongbridge sharing oversight and paying for 70 percent of the cost of the program, or approximately $4 million over a three-year period. Strongbridge expects to commercially launch MACRILEN in mid-year 2018.

AEterna Zentaris shares reacted to the news, skyrocketing over 30% in early trading Wednesday.

“We are extremely proud to acquire the U.S. and Canadian rights to MACRILEN, the first and only oral drug approved in the U.S. to diagnose adult growth hormone deficiency, or AGHD. MACRILEN has Orphan Drug Designation in the U.S. and was developed to address important unmet needs in the diagnosis and appropriate treatment of adult growth hormone deficiency, a condition that we believe is too often under-recognized or misdiagnosed, in part because of the lack of accurate, convenient and safe diagnostic procedures,” said Matthew Pauls, president and chief executive officer of Strongbridge Biopharma. “The acquisition of MACRILEN builds upon our rare endocrine disease franchise and establishes our commercial presence in the space, marking an important step forward for Strongbridge’s overall growth and evolution. Importantly, this transaction occurs prior to the potential regulatory approval and market introduction of RECORLEV™ (levoketoconazole), currently in Phase 3 for endogenous Cushing’s syndrome, a condition often treated by the same endocrinologists who diagnose and treat AGHD,” Pauls added.
