– 2018 strategy focuses on continued R&D innovation, pipeline expansion and commercialization plans for new classes of CNS therapeutics –


CAMBRIDGE, Mass.--(BUSINESS WIRE)-- SAGE Therapeutics (NASDAQ: SAGE), a clinical-stage biopharmaceutical company developing novel medicines to treat life-altering central nervous system (CNS) disorders, today announced that in a corporate presentation at the 36th Annual J.P. Morgan Healthcare Conference in San Francisco, the Company’s Chief Executive Officer, Jeff Jonas, M.D., will discuss several components of the Company’s strategy to build the business for the long term by assembling the capabilities to fully develop and commercialize important medicines. His remarks will highlight three key areas of focus in the pursuit of new classes of CNS therapies: impacting novel, fundamental brain mechanisms; addressing treatment gaps with differentiated therapies; and discovering a potentially groundbreaking approach to depressive disorders.

“The lack of adequate treatments for CNS disorders is creating a global public health crisis due to limited innovation in neuroscience research and development until now,” said Dr. Jonas. “Sage is taking on this challenge with a deliberate, planned approach. By thinking differently about CNS drug development, we are originating differentiated medicines with the potential to exceed expectations, customizing the playbook of commercialization, and disrupting conventional wisdom by creating a potential new methodology of care. In 2018, we expect to build on our track record of success, with the potential to create significant value by maximizing patient benefit.”

Dr. Jonas will provide additional detail on the following development programs:

Sage is currently focused on launch readiness and building commercial infrastructure to ensure successful commercial execution, if Sage’s proprietary formulation brexanolone is approved to address postpartum depression (PPD), a common biological complication of childbirth.

  • Filing of New Drug Application (NDA) planned in 1H 2018
  • Buildout of commercial supply chain activities on track for launch
  • Buildout of commercial infrastructure underway in anticipation of potential 1H 2019 launch

SAGE-217 and SAGE-324
Sage's novel, oral, next-generation positive allosteric modulators of synaptic and extra-synaptic GABAA receptors.


  • Major Depressive Disorder (MDD): Initiation of additional clinical studies expected in 2018
  • Postpartum Depression: Increased Phase 2 trial size in PPD with anticipated data readout in 2Q 2018
    • Positive results from SAGE-217 Phase 2 trial in MDD and positive Phase 3 results with brexanolone in PPD support maximizing utility of ongoing Phase 2 trial for overall depression development program
  • Bipolar Depression: Initiation of development program planned for 2018
  • Parkinson’s Disease: Initiation of placebo-controlled Phase 2b study planned for 2018
  • Insomnia: Results from exploratory Phase 1 placebo-controlled study expected in 1Q 2018; results to inform potential development path
  • Essential Tremor: Completed Part C of exploratory Phase 2 trial in essential tremor
    • Open-label design initiated to study higher doses and extended dosing in 18 patients
    • Improved tremor symptoms, as assessed by the Kinesia Upper Limb Combined Score, by 16% on Day 15 following two weeks of dosing. Administration of SAGE-217 was generally well-tolerated
    • The most common adverse events were somnolence, dizziness, and sedation. There were no serious adverse events reported in the study
    • Reductions in kinetic tremor measures of up to 21% at 40mg suggest twice-daily dosing may be preferable for this indication
    • Planned development efforts in essential tremor to be moved from SAGE-217 to SAGE-324 based on respective compound profiles and anticipated twice-daily dosing requirements for essential tremor


  • Essential Tremor/Epileptiform Disorders: Continuation of IND-enabling studies; initiation of Phase 1 study anticipated in 1H 2018
    • Plans to explore SAGE-324 in essential tremor based on positive exploratory placebo-controlled clinical trial with SAGE-547 and open-label essential tremor studies with SAGE-217

GABA Discovery Programs

  • Evaluating a series of novel GABAA receptor modulators in pre-clinical development, including SAGE-689, SAGE-105, and others

NMDA Programs
Sage’s novel, oral, first-in-class oxysterol-based positive allosteric modulators of the NMDA receptor.

The Company recently selected SAGE-904 as its second NMDA receptor positive allosteric modulator product candidate for development. Positive modulation of NMDA receptors may have potential in the treatment of a range of neurological disorders associated with a variety of cognitive, neurological and behavioral symptoms.


  • Initiation of Phase 1 multiple ascending dose study anticipated in 1H 2018
  • Announcement of clinical development strategy, including lead indications, planned for 2018


  • Differentiated pharmacologic and pharmacokinetic profile from SAGE-718
  • Recently initiated IND-enabling studies

2017 Year-End Cash and Guidance
Sage ended 2017 with approximately $518 million of cash, cash equivalents and marketable securities, including $325.7 million in net proceeds from a public offering completed in November 2017. Based on its current operating plans, Sage expects that its operating expenses will increase year over year in 2018 to support continued pipeline advancement and potential product commercialization of brexanolone in PPD. Sage expects to provide specific 2018 financial guidance in its fourth quarter and full year 2017 financial results announcement in February 2018.
