AMAG, Palatin Tech Strike $440 Million Female Sexual Disorder Pact
Two Phase 3 trials completed for Rekynda; co-primary endpoints met
Will address underserved medical condition with significant untapped market potential
Broadens AMAG’s presence in women’s health and leverages AMAG’s commercial capabilities and customer relationships
WALTHAM, Mass. and CRANBURY, N.J., Jan. 09, 2017 (GLOBE NEWSWIRE) -- AMAG Pharmaceuticals, Inc. (Nasdaq:AMAG) together with Palatin Technologies, Inc. (NYSE MKT:PTN) today announced they have entered into an agreement for exclusive North American rights to develop and commercialize RekyndaTM (bremelanotide), an investigational product designed for on-demand treatment of hypoactive sexual desire disorder (HSDD) in pre-menopausal women, that has successfully completed two Phase 3 trials. The anticipated filing date in the U.S. for a new drug application (NDA) for Rekynda is in early 2018, with an anticipated approval and launch by early 2019.
“AMAG is excited to expand its women’s health portfolio with a product that could address a compelling medical problem that currently is under-addressed,” said William Heiden, chief executive officer of AMAG. “Rekynda is a natural extension of our existing women’s health platform and offers us a compelling opportunity to create awareness and educate patients and providers about this condition. HSDD can significantly impact self-image, relationships and the general well-being of millions of women.”
HSDD, the most common type of female sexual dysfunction (FSD), is characterized by low sexual desire that causes marked distress or interpersonal difficulties. HSDD affects approximately 15 million women in the United States.1 Approximately 5.8 million of these women are pre-menopausal and have a primary diagnosis of HSDD.2,3,4 Despite one HSDD therapy on the market today for pre-menopausal women, patient awareness and understanding of the condition remain extremely low, and few women currently seek treatment.5 Recent market research indicates that 95 percent of pre-menopausal women suffering from HSDD are unaware that it is a treatable medical condition and that the majority of these women would try a product like Rekynda, if recommended by their doctor.6
“As a potentially safe, on-demand treatment with a fast onset of action, Rekynda could offer an important therapeutic alternative for pre-menopausal women suffering from HSDD,” said Carl Spana, Ph.D., chief executive officer of Palatin Technologies. “AMAG’s commercial capabilities are uniquely suited to raise awareness and understanding of HSDD and the potential benefits of Rekynda to both providers and patients. I am confident that AMAG will drive a successful approval and launch of Rekynda in early 2019.”
Under the terms of the license agreement, AMAG will pay to Palatin $60 million of total upfront consideration, up to $80 million contingent upon achieving certain regulatory milestones and up to $300 million contingent upon meeting certain sales milestones. The first sales milestone is $25 million and would be triggered when Rekynda annual net sales in North America exceed $250 million. Additionally, AMAG expects to reimburse Palatin for up to $25 million of ongoing development expenses incurred by Palatin in connection with the remaining development of Rekynda in 2017. AMAG will also pay Palatin tiered royalties on net sales ranging from high single-digit to low double-digit percentages. AMAG expects the transaction to close in the first quarter of 2017.
"We are excited about the potential value Rekynda will create for shareholders as we diversify our women’s health portfolio,” said Frank Thomas, president and chief operating officer of AMAG. “HSDD is an under-diagnosed medical condition with significant untapped market potential, and we believe our experience in raising awareness and building patient education programs that directly engage women creates a unique opportunity for AMAG and for millions of women across the country.”
About RekyndaTM (bremelanotide)
Rekynda (bremelanotide), an investigational product, is thought to possess a novel mechanism of action, activating endogenous melanocortin pathways involved in sexual desire and response.
The two Phase 3 studies for HSDD in pre-menopausal women consisted of double-blind placebo-controlled, randomized parallel group studies comparing a subcutaneous dose of 1.75 mg Rekynda delivered via an auto-injector pen to placebo. Each trial consisted of more than 600 patients randomized in a 1:1 ratio to either the treatment arm or placebo with a 24 week evaluation period. In both clinical trials, Rekynda met the pre-specified co-primary efficacy endpoints of improvement in desire and decrease in distress associated with low sexual desire as measured using validated patient-reported outcome instruments.
Women in the trials had the option, after completion of the trial, to continue in an ongoing open-label safety extension study for an additional 12 months. Nearly 80% of patients elected to remain in the open-label portion of the study, and all of these patients will continue to receive Rekynda.
In both Phase 2 and Phase 3 clinical trials, the most frequent adverse events were nausea, flushing, and headache (generally mild in nature).
Rekynda has no known alcohol interactions.
