AMAG And EndoCeutics Enter Into An Exclusive U.S. License Agreement For Intrarosa (Prasterone)

Recently approved first-of-its-kind, non-estrogen prescription therapy for a common symptom of menopause

Conference call scheduled for 8 a.m. ET today

WALTHAM, Mass. and QUEBEC, Feb. 14, 2017 (GLOBE NEWSWIRE) -- AMAG Pharmaceuticals, Inc. (Nasdaq:AMAG) and Endoceutics, Inc. today announced that they have entered into an exclusive license agreement that provides AMAG with U.S. commercial rights to Intrarosa™ (prasterone). Intrarosa is the only FDA-approved, locally administered, daily, non-estrogen product for the treatment of moderate-to-severe dyspareunia (pain during intercourse), a common symptom of vulvar and vaginal atrophy (VVA), due to menopause. Unlike conventional pharmacological estrogen-containing medications, Intrarosa does not carry a boxed safety warning in its label.

“AMAG is pleased to add another product to its expanding women’s health portfolio and to work with Endoceutics founder Dr. Fernand Labrie, a world-renowned endocrinologist who led the development of this innovative treatment approach,” said William Heiden, chief executive officer of AMAG. “Intrarosa will address a compelling unmet medical need for post-menopausal women suffering today from moderate-to-severe dyspareunia who are interested in alternatives to their current treatment or most of whom choose to go untreated due to safety concerns about conventional synthetic estrogen-containing therapies. We look forward to introducing this new, differentiated therapy to women and their healthcare providers.”

The transaction represents a further expansion into women’s health and is an important step in continuing to execute AMAG’s growth strategy. Earlier this month, AMAG announced the closing of a license agreement with Palatin Technologies, Inc., for the exclusive North American rights to develop and commercialize Rekynda™ (bremelanotide), a potential novel treatment for hypoactive sexual desire disorder, the most common form of female sexual dysfunction (FSD). The addition of these two products will allow AMAG to address key needs across the continuum of women’s healthcare, with three potential new product launches over the next two years, starting with Intrarosa in 2017, followed by the Makena subcutaneous auto-injector and Rekynda, if approved.

Intrarosa enters an existing billion dollar-plus market for intravaginal prescription therapies that treat VVA symptoms. There are an estimated 64 million post-menopausal women in the U.S., and as many as 32 million women suffer from VVA symptoms.1 Studies suggest that between 44 percent and 78 percent of women with VVA suffer from dyspareunia.2,3 According to patient survey data, more than half of women who report symptoms of dyspareunia are not currently being treated with a prescription therapy or seeking treatment.4

Intrarosa contains prasterone, a precursor of hormones that is converted locally inside the vaginal cells into androgens and estrogens with no meaningful increases detected in the blood. Intrarosa does not carry the boxed warnings currently included in the labels of conventional estrogen-containing medications which highlight the increased risk of certain types of cancers, such as endometrial cancer, as well as cardiovascular disorders and probable dementia. While Intrarosa is currently approved for the treatment of moderate-to-severe dyspareunia, Endoceutics and AMAG have agreed to co-develop the product as a potential treatment for FSD in post-menopausal women.

“As a non-estrogen containing treatment, Intrarosa is a novel vaginal prescription therapy that provides an important alternative for patients with moderate-to-severe dyspareunia, a common symptom of post-menopausal VVA,” said Dr. Fernand Labrie, founder and chief executive officer of Endoceutics. “Intrarosa stimulates the body’s natural ability to produce hormones locally and thus significantly reduces pain during intercourse. Because Intrarosa does not contain estrogen, patients may feel more comfortable seeking treatment than with synthetic traditional estrogen-containing hormone therapies.”

“Endoceutics is committed to ensuring that Intrarosa becomes the standard of care for the treatment of VVA. In addition to AMAG’s investments in the success of Intrarosa, Endoceutics plans to put an additional $20 million toward supporting educational programs in 2017,” Dr. Labrie continued.

AMAG will be expanding its women’s health sales force beyond the ?current? 100-person? ? Makena?- and CBR-focused team with approximately 150 additional sales representatives dedicated to the commercialization of Intrarosa. This expanded sales force will allow AMAG to call on a larger number of OB/GYNs, as well as provide AMAG with future sales force deployment flexibility in women’s health, such as the potential launch of Rekynda in early 2019. AMAG expects to launch Intrarosa in the U.S. in mid-2017.

“Three Orange Book-listed patents with terms out to 2031, a sizeable untapped market and overlap with our current physician call points make Intrarosa an excellent strategic opportunity for AMAG that will help drive growth and sustained shareholder value,” said Frank Thomas, president and chief operating officer of AMAG. “The additions of FDA-approved Intrarosa and recently licensed Rekynda will meaningfully add to our expanding women’s health portfolio. AMAG’s strong cash position, combined with the cash-generating potential of our current businesses, puts us in an excellent position to continue to pursue additional acquisition and licensing opportunities.”

Transaction Details
Under the terms of the license agreement, AMAG will receive the right to commercialize and develop Intrarosa in the U.S. for the treatment of VVA and FSD. At closing, AMAG will pay Endoceutics $50 million of total upfront consideration and issue Endoceutics 600,000 unregistered shares of AMAG common stock. In addition, AMAG will pay Endoceutics up to $10 million upon delivery of adequate launch quantities of Intrarosa and $10 million upon the first anniversary of the effective date of the agreement. Endoceutics will be entitled to certain sales milestone payments, including a first sales milestone payment of $15 million, which would be triggered when Intrarosa annual net U.S. sales exceed $150 million, and a second milestone payment of $30 million, which would be triggered when annual net U.S. sales exceed $300 million. Should annual net U.S. sales exceed $500 million, there are additional sales milestone payments of up to $850 million, which would be triggered at various sales thresholds. AMAG will also pay Endoceutics tiered royalties as a percent of Intrarosa net sales ranging from the mid-teens (for calendar year net sales up to $150 million) to the mid-twenties (for any calendar year net sales that exceed $1 billion). At closing, AMAG and Endoceutics will also enter into a supply agreement, under which Endoceutics will supply Intrarosa to AMAG.

AMAG has also committed to co-fund a Phase 3 clinical program, which would be conducted by Endoceutics to support regulatory approval of Intrarosa for the treatment of certain types of FSD in post-menopausal women. The direct costs of the potential FSD label expansion study will be shared equally by the parties and capped at up to $20 million for AMAG. The transaction does not include the transfer of any Endoceutics employees or facilities.

The license transaction is expected to close in the first half of 2017 and is subject to customary closing conditions, including U.S. antitrust approval.

EVOLUTION Life Science Partners LLC, a division of Gordian Investments, LLC acted as advisor to Endoceutics. Goodwin Procter LLP served as AMAG’s legal advisor on the transaction and Cooley LLP served as legal advisor to Endoceutics.

About Intrarosa™ (Prasterone)
Intrarosa is the only FDA-approved, locally administered, daily non-estrogen steroid for the treatment of moderate-to-severe dyspareunia (pain during intercourse), a symptom of vulvar and vaginal atrophy (VVA), due to menopause. Intrarosa contains prasterone, also known as dehydroepiandrosterone (DHEA). Prasterone is an inactive endogenous steroid, which is converted locally into androgens and estrogens to help restore the vaginal tissue as indicated by improvements in the percentage of superficial cells, parabasal cells, and pH. The mechanism of action is not fully established.

In two primary 12-week placebo-controlled efficacy trials, women taking Intrarosa experienced a significant reduction in dyspareunia, as well as significant improvements in the percentage of vaginal superficial cells and parabasal cells, as well as vaginal pH. In clinical trials, the most common adverse reactions were vaginal discharge and abnormal pap smear. Intrarosa has not been studied in women with a history of breast cancer.
