CAMBRIDGE, Mass., April 29, 2025--(BUSINESS WIRE)--Sage Therapeutics, Inc. (Nasdaq: SAGE), today reported business highlights and financial results for the first quarter ended March 31, 2025.

"We delivered strong growth in revenue and shipments of ZURZUVAE during the first quarter of 2025 through the team’s disciplined execution and unwavering commitment to bringing ZURZUVAE to more women with postpartum depression," said Barry Greene, Chief Executive Officer at Sage Therapeutics. "We remain focused on establishing ZURZUVAE as the standard of care for women with postpartum depression and driving our business strategy forward with the goal of creating value for shareholders."

First Quarter 2025 Portfolio Updates

ZURZUVAE

ZURZUVAE was approved by the FDA in August 2023 as the first-and-only oral treatment indicated for adults with postpartum depression (PPD). ZURZUVAE was made commercially available in the U.S. in December 2023. The current commercialization investment plan includes recent joint sales force expansions and marketing tactics intended to further accelerate ZURZUVAE growth in PPD, along with expanded disease state awareness efforts to support increased PPD screening and diagnosis. The Company anticipates these investments will help support the goal of significant topline revenue growth in 2025. As of the first quarter ended March 31, 2025, the following results had been achieved:

• Shipped greater than 3,000 prescriptions to women with PPD, representing a 22% increase from the fourth quarter.
• Generated $13.8 million in collaboration revenue from ZURZUVAE, representing a 21% increase from the fourth quarter of 2024. Collaboration revenue represents 50% of the net revenue recorded when Biogen ships ZURZUVAE to the distributors.

In terms of prescriber and patient trends:

• In the first quarter of 2025, OBGYNs accounted for almost 80% of all prescriptions.
• OBGYNs are, on average, increasing the number of women with PPD they treat once they have prescribed ZURZUVAE, which we believe reflects the high unmet need in PPD and potential value of ZURZUVAE.
• More than 70% of women prescribed ZURZUVAE are receiving it as their first new treatment for PPD.

SAGE-319

SAGE-319 is an extrasynaptic-preferring GABA_A receptor positive allosteric modulator (PAM) designed to have novel pharmacology and a differentiated clinical profile from other GABA_A receptor 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 based on these data.

Pre-Clinical

The Company is continuing to explore targeted work within its NMDA receptor negative allosteric modulator (NAM) platform, focusing on potential treatments for neurodevelopmental disorders, with SAGE-817 and SAGE-039.

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.

Strategic Alternatives Review Process

As previously announced, Sage’s Board of Directors is evaluating a broad range of strategic alternatives to maximize value for shareholders. The Board’s review process remains ongoing. The Company has not set a timetable for the review process and does not intend to disclose further developments until it determines that disclosure is appropriate or necessary.

FINANCIAL RESULTS FOR THE FIRST QUARTER 2025

• Cash Position: Cash, cash equivalents and marketable securities as of March 31, 2025, were $424 million compared to $504 million at December 31, 2024.

• Revenue: Collaboration revenue from sales of ZURZUVAE was $13.8 million in the first quarter of 2025 compared to $6.2 million for the same period in 2024. Reported collaboration revenue is 50% of the net revenue Biogen records for ZURZUVAE in the U.S. There was no net revenue from sales of ZULRESSO in the first quarter of 2025 compared to $1.7 million in the same period of 2024.

• Cost of Revenues: Cost of revenues were $0.7 million in the first quarter of 2025, which consisted of costs related to selling ZURZUVAE, compared to $1.3 million for the same period in 2024, which consisted of costs related to selling ZURZUVAE and ZULRESSO.

• R&D Expenses: Research and development expenses were $22.8 million, including $2.1 million of non-cash stock-based compensation expense, in the first quarter of 2025 compared to $71.7 million, including $5.0 million of non-cash stock-based compensation expense, for the same period in 2024. The decrease in R&D expenses in the first quarter of 2025 as compared to the same period in 2024 was primarily related to the 2024 and 2023 reorganization cost savings measures, including reduced headcount, budgeted expenditures, reprioritization of early-stage pipeline programs, and completion or cancellation of ongoing clinical trials. The reimbursement from Biogen to Sage for R&D expenses pursuant to the Sage/Biogen Collaboration and License Agreement was $0.2 million in the first quarter of 2025 compared to $5.7 million in the same period of 2024. The primary reason for the decrease in net reimbursement from Biogen to Sage was a decrease in the collaboration costs incurred by Sage for clinical trials.

• SG&A Expenses: Selling, general and administrative expenses were $57.6 million, including $4.9 million of non-cash stock-based compensation expense, in the first quarter of 2025 compared to $52.6 million, including $8.7 million of non-cash stock-based compensation expense, for the same period in 2024. The overall increase in SG&A expenses in the first quarter of 2025 as compared to the same period in 2024 was primarily related to increased collaboration commercialization efforts and legal expenses associated with the strategic alternatives review process. The reimbursement from Sage to Biogen for SG&A expenses pursuant to the Sage/Biogen Collaboration and License Agreement was $4.8 million in the first quarter of 2025 compared to $2.3 million in the same period of 2024. The primary reason for the increase in net reimbursement from Sage to Biogen was an increase in the collaboration costs incurred by Biogen in support of ongoing commercialization efforts for ZURZUVAE.
• Restructuring Expenses: Restructuring expenses were $0.5 million in the first quarter of 2025 due the October 2024 reorganization.

• Net Loss: Net loss was $62.2 million for the first quarter of 2025 compared to $108.5 million for the same period in 2024.

FINANCIAL GUIDANCE

• Based on the Company’s current operating plan, Sage anticipates that its existing cash, cash equivalents, and marketable securities as of March 31, 2025, together with anticipated funding from ongoing collaborations and estimated revenues, excluding any potential milestone payments the Company may receive under its collaboration agreements, will support operations to mid-2027.

• While ZURZUVAE joint commercialization investment will increase in 2025, the Company anticipates overall operating expenses will substantially decrease in 2025 relative to 2024.

These forward-looking statements are neither promises nor guarantees of future performance, and are subject to a variety of risks and uncertainties, many of which are beyond our control, which could cause actual results to differ materially from those contemplated in these forward-looking statements, including the risks that: our commercialization efforts in the U.S. with respect to ZURZUVAE for the treatment of women with PPD may not be successful, and we may be unable to generate revenues from sales of ZURZUVAE at the levels or on the timing we expect or at levels or on the timing necessary to support our goals; 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; early positive signs, including ZURZUVAE results in 2024 and the first quarter of 2025, may not be a signal of future success; ZURZUVAE may not achieve, or even if achieved, maintain, the clinical benefit, clinical use or market acceptance for the treatment of PPD that we expect, including among OBGYNs, or we may encounter reimbursement, market access, process-related, or other issues, including competition in the market, or issues with our distribution network that impact the success of our commercialization efforts; ZURZUVAE may never become the standard of care for women with PPD; we may encounter delays in initiation, conduct, completion of enrollment or completion and reporting of data with respect to any of our ongoing studies or 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 non-clinical or 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;

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 expenses and use of cash, may be higher than expected, which may cause us to use cash quicker than expected 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; we may not achieve revenues from our products that may be successfully developed in the future at levels we expect; our exploration of strategic alternatives could result in substantial costs and be a distraction to management and other employees, which could have an adverse effect on our business; the strategic alternatives review process may not result in any transaction or strategic outcome; if we determine to engage in a transaction as a result of our exploration and evaluation of strategic alternatives, our future business, prospects, financial position and operating results could be significantly different than those in historical periods or projected by our management; additional funding may not be available on acceptable terms when we need it, or at all, which could hamper our development and commercialization activities; any of the foregoing events could impair the drivers and value creation opportunities for our business;
