• Excitement over December 2023 launch of ZURZUVAE™ (zuranolone), the first and only oral treatment indicated for adults with postpartum depression (PPD)
• Continued progress on clinical pipeline, with topline data expected from multiple ongoing Phase 2 trials across 2024
• Catalyst rich year supported by strong financial foundation and focused execution

CAMBRIDGE, Mass. / Jan 08, 2024 / Business Wire / Sage Therapeutics, Inc. (Nasdaq: SAGE), a biopharmaceutical company leading the way to create a world with better brain health, today announced that Chief Executive Officer Barry Greene will discuss the Company’s key business drivers for 2024 at the 42nd Annual J.P. Morgan Healthcare Conference in San Francisco, California.

As part of this presentation, Mr. Greene will discuss commercialization of ZURZUVAE™ (zuranolone), the first and only once-daily 14-day oral treatment option for adults with postpartum depression (PPD) and will provide an update on the Company’s progress in advancing its brain health pipeline.

“The landmark FDA approval of ZURZUVAE has fueled additional momentum in recognizing the urgency to treat PPD, which reinforces our belief that all women with PPD who are prescribed ZURZUVAE should be able to access it. While early, we are encouraged by the positive engagement we have had in the initial launch weeks, and we believe we are off to a great start – patients are being prescribed ZURZUVAE by multiple specialties, including OBGYNs, and we are seeing enthusiasm from prescribers to learn more,” said Barry Greene, CEO at Sage Therapeutics. “We are also making progress across our pipeline and look forward to several clinical data milestones in the dalzanemdor (SAGE-718) and SAGE-324 programs this year. We head into 2024 poised for a catalyst-rich year further supported by a strong financial foundation and focused execution plans.”

Commercial availability of ZURZUVAE™ (zuranolone) underway to support women with PPD

Sage and its collaborator, Biogen, are focused on establishing ZURZUVAE as the first line therapy and standard of care for women with PPD. The companies recently announced commercial availability of ZURZUVAE and the specialty pharmacy distribution model by which ZURZUVAE is shipped directly to patients who are prescribed the treatment. Sage and Biogen field sales teams are engaging in promotional dialogues with health care professionals (HCPs) who actively identify and treat women with PPD. Since commercial availability, HCPs, including OBGYNs, psychiatrists, and primary care physicians have started to prescribe ZURZUVAE in this indication. The companies are continuing active discussions with national, regional and government payors to advocate for broad and equitable access to ZURZUVAE for women with PPD with minimal restrictions and expect formulary discussions to continue over the course of 2024.

Innovative brain health pipeline with potential for significant value creation

Sage is advancing a portfolio of early-stage and clinical programs featuring internally discovered novel chemical entities targeting the GABA_A and NMDA receptor systems. The Company expects several clinical data milestones in 2024 for dalzanemdor (SAGE-718) and SAGE-324.

Dalzanemdor (SAGE-718), the Company’s first-in-class NMDA receptor positive allosteric modulator (PAM), is in development as a potential oral therapy for cognitive disorders associated with NMDA receptor dysfunction, including Huntington’s disease (HD), Alzheimer’s disease (AD) and Parkinson’s disease (PD). In Q4 2023, the FDA granted Orphan Drug Designation to SAGE-718 for the treatment of HD, and the United States Adopted Name (USAN) Council assigned the nonproprietary name of “dalzanemdor” to this compound.

Topline data from ongoing Phase 2 studies are expected in 2024 across all indications, including the following anticipated read-outs:

- PRECEDENT study in people with mild cognitive impairment (MCI) associated with PD in early-2024

- SURVEYOR study in people with HD cognitive impairment in mid-2024

- LIGHTWAVE study in people with mild cognitive impairment and mild dementia due to AD in late-2024

- DIMENSION study in people with HD cognitive impairment in late-2024

SAGE-324, the Company’s next-generation PAM of GABA_A receptors, is in development as a potential oral therapy for movement disorders, such as essential tremor (ET). SAGE-324 is being developed in collaboration with Biogen Inc. Topline data from the Phase 2b KINETIC study in ET are expected in mid-2024.
