AMAG PHARMACEUTICALS ANNOUNCES FDA APPROVAL OF VYLEESI™ (BREMELANOTIDE INJECTION) FOR ACQUIRED, GENERALIZED HYPOACTIVE SEXUAL DESIRE DISORDER (HSDD) IN PREMENOPAUSAL WOMEN
The First FDA-Approved As-Needed Treatment for Premenopausal Women Experiencing Distress or Interpersonal Difficulty Due to Low Sexual Desire
1 in 10 Premenopausal Women in the U.S. (Approximately 6 Million Women) Suffer From HSDD
WALTHAM, Mass. June 21, 2019 – AMAG Pharmaceuticals, Inc. (NASDAQ:AMAG) announced today that the U.S. Food and Drug Administration (FDA) has approved Vyleesi™ (bremelanotide injection), a melanocortin receptor agonist, to treat acquired, generalized hypoactive sexual desire disorder (HSDD) in premenopausal women. The Vyleesi autoinjector is the first treatment for this patient population that can be self-administered as needed in anticipation of sexual activity.
HSDD is characterized by low sexual desire that causes distress or interpersonal difficulty and is not due to a co-existing medical or psychiatric condition, problems within the relationship, or the effects of a medication or other drug substance.
“HSDD has been recognized as a medical condition since the 1970s, yet it has been widely underdiagnosed and undertreated,” said Anita H. Clayton, M.D., Chair, Department of Psychiatry & Neurobehavioral Sciences, University of Virginia School of Medicine, VA. “Women with HSDD often avoid situations that could lead to intimacy, the impact of which goes far beyond the bedroom and can often result in anxiety, loss of vitality, self-esteem issues and relationship stress. It is important that women suffering with this condition have a choice of treatment options available to them.”
HSDD is thought to have a neurobiologic basis which is supported by brain imaging studies. When study participants were shown visual sexual stimuli, there was a difference in the brain activation patterns between women with HSDD compared to those women without HSDDi.
“Today's approval underscores AMAG’s commitment to women’s health and dedication to raising awareness and improving education about HSDD,” said Julie Krop, M.D., chief medical officer at AMAG. “While HSDD is the most common female sexual dysfunction condition, it is largely under-recognized. I want to thank the thousands of women who participated in the clinical trials to support the approval of Vyleesi. Their participation in the trials helped to pave the way for a novel treatment option that offers hope to the nearly six million premenopausal women who have suffered in silence from HSDD—empowering them to reclaim their sexual desire.”
The FDA approval of Vyleesi is based upon data from approximately 1,200 women in two pivotal, double-blind placebo controlled Phase 3 trials (RECONNECT). In both clinical trials, Vyleesi met the pre-specified co-primary efficacy endpoints of improvement in desire and reductions in distress as measured by validated patient-reported outcome instruments. Upon completion of the trial, women had the option to continue in a voluntary open-label safety extension study for an additional 12 months. Nearly 80 percent of patients who completed the
Phase 3 trials elected to remain in the open-label portion of the study, where all of these patients received Vyleesi.
In the pivotal trials, the most common adverse events were nausea, flushing, injection site reactions, and headache. The majority of events were reported to be transient and mild-to-moderate in intensity. In clinical trials, Vyleesi caused small, transient increases in blood pressure, and is contraindicated in women with uncontrolled high blood pressure or known cardiovascular risk.
AMAG is committed to working with payers and healthcare professionals to help ensure women with HSDD have access to Vyleesi. The product will be commercially available in September through select specialty pharmacies. To raise healthcare provider awareness of Vyleesi, AMAG will leverage its existing women’s and maternal health sales force of approximately 125 sales representatives calling on U.S. obstetrics, gynecologists and sexual medicine specialists, and will also offer patients the ability to connect with a physician through a telemedicine option. Patients and providers can learn more about HSDD and Vyleesi at www.vyleesi.com and sign up to receive information about how to obtain Vyleesi as soon as it is available.
AMAG in-licensed Vyleesi from Palatin Technologies, Inc. in February 2017. Under the terms of the agreement, the approval of Vyleesi by the FDA triggers a $60 million payment obligation to Palatin. In addition, AMAG will pay Palatin tiered royalties on annual net sales of Vyleesi ranging from the high-single digits to the low double-digits. AMAG will also pay Palatin sales milestones based on escalating annual net sales thresholds, the first of which is $25 million, triggered at annual net sales of $250 million.
About Vyleesi™ (bremelanotide injection)
Vyleesi is approved for the treatment of premenopausal women with acquired, generalized hypoactive sexual desire disorder (HSDD). The prefilled Vyleesi autoinjector pen is self-administered into a woman’s abdomen or thigh at least 45 minutes before anticipated sexual activity and can be taken at any time of day. Vyleesi is thought to possess a novel mechanism of action. While the exact mechanism of action is unknown, Vyleesi is believed to bind to melanocortin receptors in the central nervous system. Vyleesi has no known alcohol restrictions.
Vyleesi (bremelanotide injection) Important Safety Information
Contraindications
VYLEESI is contraindicated in patients who have uncontrolled hypertension or known cardiovascular disease.
Warnings and Precautions
Transient Increase in Blood Pressure and Decrease in Heart Rate: VYLEESI transiently increases blood pressure and reduces heart rate after each dose. Advise patients that these changes usually resolve within 12 hours. VYLEESI is not recommended in patients at high risk for cardiovascular disease. Consider the patient’s cardiovascular risk before initiating VYLEESI and periodically during treatment and ensure blood pressure is well-controlled. To minimize the risk of more pronounced blood pressure effects, patients should not take more than one VYLEESI dose within 24 hours. Patients should not use more than 8 VYLEESI doses per month.
Focal Hyperpigmentation: Reported by 1% of patients who received up to 8 doses per month, including involvement of the face, gingiva and breasts. Patients are at higher risk of developing focal hyperpigmentation if they have darker skin and with daily dosing. Resolution of the focal hyperpigmentation was not confirmed in all patients after discontinuation of VYLEESI. Consider discontinuing VYLEESI if hyperpigmentation develops.
Nausea: Reported by 40% of patients who received up to 8 monthly doses, requiring anti-emetic therapy in 13% of patients and leading to premature discontinuation for 8% of patients. Nausea improves for most patients with
the second dose. Consider discontinuing VYLEESI or initiating anti-emetic therapy for persistent or severe nausea.
Adverse Reactions
Most common adverse reactions (incidence >4%) are nausea, flushing, injection site reactions, headache, and vomiting.
Drug Interactions
VYLEESI may slow gastric emptying and impact absorption of concomitantly administered oral medications. VYLEESI may significantly decrease the systemic exposure of orally-administered naltrexone; avoid use with orally administered naltrexone-containing products intended to treat alcohol or opioid addiction.
Pregnancy
Advise patients to discontinue VYLEESI if pregnancy is suspected. Advise patients to use effective contraception while taking VYLEESI.
There will be a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to VYLEESI during pregnancy. Pregnant women exposed to VYLEESI and healthcare providers are encouraged to call the VYLEESI Pregnancy Exposure Registry at 1-877-411-2510.
