CAMBRIDGE, Mass., Jan. 12, 2015 (GLOBE NEWSWIRE) -- SAGE Therapeutics (Nasdaq:SAGE), a clinical-stage biopharmaceutical company developing novel medicines to treat life-threatening, rare central nervous system (CNS) disorders, today announced dose administration of the first patient in a Phase 2a clinical trial of SAGE-547, an allosteric modulator of GABAA receptors, in women with severe postpartum depression (PPD), a distinct and readily identified form of major depressive disorder estimated to affect 15 to 20 percent of women following childbirth. This trial is designed to evaluate the safety, tolerability, pharmacokinetics and efficacy of SAGE-547 for the treatment of severe PPD.
“Postpartum depression is a serious medical condition that can have a devastating effect on the patient and her family. Therapeutic options for PPD are extremely limited, and there is a great need for new medicines to aid patients suffering with this disorder,” said Steve Kanes, M.D., Ph.D., chief medical officer of SAGE Therapeutics. “This form of depression has been characterized by demonstrated abnormalities of allopregnanolone levels and has a stereotypical time of onset, allowing for the identification of a homogeneous patient population. Given preclinical data demonstrating that SAGE-547 impacts biological processes that are dysregulated in reproductive hormone-related mood disorders like PPD, we believe this represents an important opportunity to evaluate SAGE-547’s mechanism of action in this indication.”
This Phase 2a trial is an open-label study of SAGE-547 as an adjunctive therapy, or treatment given with current therapeutic approaches, in patients with severe PPD. This trial is expected to enroll at least 10 women with severe PPD who have experienced a major depressive episode within four weeks following delivery. This trial is designed to provide data regarding safety, tolerability and the acute effect of SAGE-547 on depressive symptoms as measured by the Hamilton Rating Scale for Depression (HAM-D) and Clinical Global Impression-Improvement Scale (CGI-I), respectively. Patients will be administered SAGE-547 intravenously for 48 hours and will be monitored for up to 30 days following treatment. The study is being conducted by Samantha Meltzer-Brody, M.D., Director of the Perinatal Psychiatry Program, University of North Carolina Center for Women’s Mood Disorders and Principal Investigator of the study.
“SAGE-547 is a potent and selective modulator of GABAA, a receptor that plays a role in many CNS disorders but has been difficult to target effectively without considerable accompanying side effects,” said Jeff Jonas, M.D., chief executive officer of SAGE Therapeutics. “Given the clinical data already available regarding the activity of SAGE-547, we believe this study will provide important insights into the potential for SAGE-547 and related compounds to impact the treatment of this disorder.”
About SAGE-547
SAGE-547 is an allosteric modulator of both synaptic and extra-synaptic GABAA receptors. GABAA receptors are widely regarded as validated drug targets for a variety of disorders, with decades of research and multiple approved drugs targeting these receptor systems. SAGE-547 is an intravenous agent in Phase 1/2 clinical development as an adjunctive therapy, a therapy combined with current therapeutic approaches, for the treatment of super-refractory status epilepticus (SRSE), as well as in exploratory Phase 2 clinical trials for the treatment of essential tremor and as an adjunctive therapy for the treatment of severe postpartum depression (PPD). In 2014, the U.S. Food and Drug Administration (FDA) granted both Fast Track and orphan drug designation to SAGE-547 for the treatment of SRSE.
About Postpartum Depression
Postpartum Depression (PPD) is a major depressive disorder that occurs in approximately 15 to 20 percent of women who have recently given birth, with up to 10 percent classified as suffering from severe PPD1,2. PPD may have devastating consequences for a woman and for her family, including depressed mood and/or loss of interest in her newborn, and associated symptoms of depression such as loss of appetite, difficulty sleeping, motor challenges, lack of concentration, loss of energy, poor self-esteem and suicidality. PPD is reported to be the most under-diagnosed obstetric complication in the U.S.3 and current therapeutic options for severe PPD are limited.
About SAGE Therapeutics
SAGE Therapeutics is a clinical-stage biopharmaceutical company committed to developing and commercializing novel medicines to treat life-threatening, rare central nervous system, or CNS, disorders. SAGE’s lead program, SAGE-547, is in clinical development for super-refractory status epilepticus, or SRSE, and is the first of several compounds the company is developing in its portfolio of potential seizure medicines. The active pharmaceutical ingredient has been contributed under agreement by the Regents of the University of California and the University of California, Davis. SAGE’s proprietary chemistry platform has generated multiple new compounds that target GABAA and NMDA receptors, which are broadly accepted as impacting many psychiatric and neurological disorders.
