Sage Therapeutics to Present 2025 Strategic Focus at 43rd Annual J.P. Morgan Healthcare Conference

Increased investment in ZURZUVAE to help accelerate market growth in postpartum depression with the goal of topline revenue growth in 2025

R&D and G&A expenses expected to decrease substantially in 2025

Company anticipates extended cash runway to mid-2027

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Sage Therapeutics, Inc. (Nasdaq: SAGE) today announced that Chief Executive Officer Barry Greene will discuss the Company’s strategic focus areas for 2025 at the 43rd Annual J.P. Morgan Healthcare Conference in San Francisco, California.

As part of this presentation, Mr. Greene will discuss the ongoing commercialization and strategic growth plans for ZURZUVAE® (zuranolone), the first and only once-daily 14-day oral treatment for adults with postpartum depression (PPD). Mr. Greene will also discuss the Company’s recalibrated R&D approach and its prioritized pipeline focused on neurodevelopmental disorders and neuropsychiatry. R&D and G&A expenses are expected to decrease substantially in 2025.

"ZURZUVAE's first year has demonstrated its potential to become the standard of care for postpartum depression, a condition with significant need where treatment options were once limited. We are building on this foundation with a strategic plan to scale and accelerate growth and ultimately help more women with PPD, which is our top priority,” said Barry Greene, Chief Executive Officer, Sage Therapeutics. “With the commercial momentum behind ZURZUVAE, a focused approach to R&D, and an extended cash runway to mid-2027, we believe Sage is well positioned for commercial growth and value creation.”

2025 Areas of Focus:

ZURZUVAE: Sage is focused on the goal of establishing ZURZUVAE as the first line therapy and standard of care for women with PPD. The current commercialization investment plan includes joint sales force expansions and planned digital marketing campaigns to help expand market growth in PPD, along with increased disease state awareness efforts to support improved PPD screening and diagnosis. The Company anticipates these investments will help support the goal of topline revenue growth in 2025.

SAGE-319: SAGE-319 is an extrasynaptic-preferring GABAA receptor positive allosteric modulator (PAM) designed to have a novel pharmacology and a differentiated clinical profile from other GABA_A PAMs in our portfolio. It is currently being investigated as a potential treatment for behavioral symptoms associated with certain neurodevelopmental disorders. The Company expects data from a Phase 1 multiple ascending dose (MAD) study by late 2025, and will evaluate next steps, if any, based on these data.

Areas In Evaluation:

SAGE-324: The Company is evaluating potential indications, including seizures in developmental and epileptic encephalopathies (DEEs), and expects to provide an update on next steps, if any, in mid-2025.

Early Discovery: The Company is continuing to explore targeted early discovery work within its NMDA NAMs platform.

Financial Guidance

Based upon the Company's current operating plan, Sage anticipates that its existing cash, cash equivalents and marketable securities as of September 30, 2024, together with anticipated funding from ongoing collaborations and estimated revenues, will support its operations to mid-2027.​ While ZURZUVAE joint commercialization investment with Biogen will increase in 2025, the Company anticipates overall operating expenses will substantially decrease relative to 2024, reflecting reductions in R&D and G&A with pipeline prioritization and the cost savings from the 2024 reorganization expected to be realized starting in Q1 2025.

the number of women with PPD, the unmet need for additional treatment options, and the potential market for ZURZUVAE for the treatment of women with PPD, may be significantly smaller than we expect; ZURZUVAE may not achieve the clinical benefit, clinical use or market acceptance for the treatment of PPD we expect or we may encounter reimbursement, market access, process-related or other issues, including competition in the market, that impact the success of our commercialization efforts; ZURZUVAE may never become the first line treatment and standard of care for women with PPD; our increased investment in the commercialization of ZURZUVAE for the treatment of women with PPD may not have the expected impacted; we may encounter delays in initiation, conduct, completion of enrollment or completion and reporting of data with respect to any of our ongoing clinical trials, such as the completion of the multiple ascending dose study for SAGE-319, including as a result of slower than expected site initiation, slower than expected enrollment, the need or decision to expand the trials or other changes, that may impact our ability to meet our expected timelines and may increase our costs; success in earlier clinical trials of any of our product candidates may not be repeated or observed in ongoing or future studies, and ongoing and future clinical trials may not meet their primary or key secondary endpoints, which may substantially impair development; unexpected concerns may arise from additional data, analysis or results from any of our completed studies; decisions or actions of the FDA or the timing of meetings with the FDA may affect the timing, design, size, progress and cost of clinical trials or the timing of data read-outs or our ability to proceed with further development or may impair the potential for successful development or the timing or success of filing for and gaining regulatory approval;

our business may be adversely affected and our costs may increase if any of our key collaborators fails to perform its obligations or terminates our collaboration; the internal and external costs required for our ongoing, planned and other future activities, and the resulting impact on expense and use of cash, may be higher than expected, which may cause us to use cash more quickly than we expect or change or curtail some of our plans or both; our expectations as to expenses, cash usage, potential revenue, funding from collaborations, including milestones, cash runway and cash needs may prove not to be correct for other reasons such as changes in plans or actual events being different than our assumptions; we may not achieve anticipated cost savings from our October 2024 reorganization and pipeline prioritization efforts at the levels we expect; we may be opportunistic in our future financing plans even if available cash is sufficient; we may not be successful in our efforts to gain regulatory approval of products beyond ZURZUVAE and ZULRESSO; we may not achieve revenues from our products that may be successfully developed in the future at levels we expect; additional funding may not be available on acceptable terms when we need it, which could hamper our development and commercialization activities; any of the foregoing events could impair the drivers and value creation opportunities for our business; and we may encounter technical and other unexpected hurdles in the development and manufacture of our product candidates or the commercialization of any current or future marketed product, which may delay our timing or change our plans, increase our costs or otherwise negatively impact our business;
