Sage Therapeutics and Biogen Announce SAGE-324 Phase 2 Placebo-Controlled KINETIC Study in Essential Tremor Met Primary Endpoint

Statistically significant reduction in tremor score compared to placebo at Day 29 in adults with essential tremor

SAGE-324 demonstrated a 36% reduction in upper limb tremor amplitude from baseline at Day 29 in the total studied population; in a more severe population (baseline TETRAS Upper Limb Item 4 >12), SAGE-324 demonstrated a 41% reduction in upper limb tremor amplitude compared to baseline

SAGE-324 demonstrated a safety profile generally consistent with previously reported data

Sage Therapeutics to host conference call today at 8 a.m. ET

CAMBRIDGE, Mass., April 12, 2021 – Sage Therapeutics, Inc. (Nasdaq: SAGE) and Biogen Inc. (Nasdaq: BIIB) today reported topline results from the Phase 2 KINETIC Study evaluating SAGE-324 in the treatment of people with essential tremor (ET). The study (n=67 full analysis set) achieved its primary endpoint of a statistically significant reduction from baseline compared to placebo in The Essential Tremor Rating Assessment Scale (TETRAS) Performance Subscale Item 4 upper limb tremor score on Day 29 (P=0.049), which corresponded to a 36% reduction from baseline in upper limb tremor amplitude in patients receiving SAGE-324 compared to a 21% reduction in patients receiving placebo. Activities of daily living (ADL) scores showed a statistically significant correlation with upper limb tremor score at all timepoints. While not powered to fully examine TETRAS ADL, SAGE-324 was numerically superior to placebo at all time points. Reported treatment-emergent adverse events (TEAEs) were generally consistent with the safety profile of SAGE-324 to date.

In the KINETIC Study, patients (n=47) with a more severe tremor at baseline (at or above the median TETRAS Performance Subscale upper limb tremor Item 4 score of 12) who received SAGE-324, demonstrated a statistically significant reduction (P=0.007) from baseline in TETRAS Performance Subscale Item 4 upper limb tremor score compared to placebo at Day 29, corresponding to a 41% reduction from baseline in upper limb tremor amplitude in patients receiving SAGE-324 compared to an 18% reduction for placebo. Study patients were not taking other medications for ET during the 28-day treatment period.

The collaboration partners are pleased with the progress to date and are planning next steps for development of SAGE-324.

“In the design of the KINETIC Study, we set a high bar and believe we exceeded it. SAGE-324 met the primary endpoint in the trial and demonstrated a safety profile generally consistent with previously reported data. The strong correlation observed in this study between TETRAS performance scale – measuring reduction of upper limb tremor, a disabling symptom experienced by more than 90% of people suffering from essential tremor — and improvement on the ADL score provides suggestive evidence that these findings have the potential to be truly impactful for people with essential tremor,” said Barry Greene, chief executive officer at Sage Therapeutics. “We believe the data announced today provide clear support and insights for the continued development of SAGE-324 in an area of significant unmet medical need. People with brain health disorders have been conditioned to accept the status quo due to limited innovation or the lack of truly transformative medicines in recent years – and that’s certainly been the case with essential tremor. However, at Sage, we believe that people suffering from brain health disorders deserve better and we aim to help achieve that.”

“We are encouraged by the positive results of the KINETIC Study, which indicate that SAGE-324 may provide relief in people suffering with essential tremor, a movement disorder that affects an estimated 6.4 million people – and is one of the most common movement disorders – in the United States,” said Alfred Sandrock, Jr., M.D., Ph.D., Head of Research and Development at Biogen. “For people with essential

tremor, uncontrollable shaking of the hands, head, voice, or legs can create difficulty eating, dressing, writing, and pursuing other day-to-day tasks. It is our hope that, in collaboration with Sage, we will be able to deliver an innovative and meaningful new treatment option for these patients. The positive results of the KINETIC Study represent one step further towards that goal, and also underscore Biogen’s commitment to delivering new therapeutic options to patients living with movement disorders that have high medical unmet need, including essential tremor.”

“There is an extraordinary unmet need for people suffering with essential tremor, a condition that can cause significant disability in patients,” said Dr. Rodger Elble, M.D., a neurologist at the Southern Illinois University School of Medicine. “The only approved medicine was developed more than 50 years ago, and most medicines used for ET were developed for other conditions, and their benefits to people with ET were only discovered serendipitously. Current investigational drugs like SAGE-324, if successful, may offer potential for new treatment options for tremor management, as more than 50% of people with ET do not respond optimally to the current standard of care.”

Full data from the KINETIC Study will be shared at future scientific forums and in publications.

Summary of Topline Results from KINETIC Study

In the KINETIC Study, SAGE-324 taken orally, once daily in the morning, showed a statistically significant reduction from baseline in upper limb tremor score as measured by Item 4 of TETRAS Performance Subscale on Day 29 compared to placebo. TETRAS Scale includes two subscales: the Performance Subscale and the Activities of Daily Living (ADL) Subscale. The TETRAS Performance Subscale is a validated, physician-administered scale designed to provide an accurate, comprehensive assessment of ET motor symptoms and has been shown to correlate with TETRAS ADL. The Performance Subscale includes Item 4, which measures upper limb tremor.

Primary Endpoint

Patients receiving SAGE-324 experienced a statistically significant reduction from baseline in TETRAS Performance Subscale Item 4 compared to placebo at Day 29 (P=0.049), corresponding to a 36% reduction in upper limb tremor amplitude from baseline in the SAGE-324 group compared to a 21% reduction in the placebo group. The analysis is based on the prespecified Full Analysis Set.

Safety and Tolerability

Patients were randomized 1:1 to receive SAGE-324 (60 mg) or matched placebo once daily in the morning. The trial evaluated treatment of SAGE-324 at the higher end of the dose range and the daily dose could be down-titrated to 45 mg or 30 mg if 60 mg was not well tolerated. Down-titration of dose occurred in 62% of patients who received SAGE-324 and discontinuations were noted in 38% of patients receiving SAGE-324. Adverse events were generally consistent with the safety profile of SAGE-324 seen to date. The most common TEAEs that occurred in ³10% of patients in the SAGE-324 treatment group and at a rate at least twice as high as that of patients in the placebo group were: somnolence 68%; dizziness 38%; balance disorder 15%; diplopia 12%; dysarthria 12%; and gait disturbance 12%.

Sage Therapeutics Conference Call Information

Sage will host a conference call and webcast today, Monday, April 12, at 8:00 a.m. ET to discuss the KINETIC Study topline results. The live webcast can be accessed on the investor page of Sage’s website at investor.sagerx.com.

About Essential Tremor

Essential Tremor (ET) is one of the most common movement disorders in the United States, affecting an estimated 6.4 million Americans. For ET patients, uncontrollable shaking of the hands, head, voice, or legs creates difficulty eating, dressing, writing, and pursuing other day-to-day tasks. While ET is often associated with aging populations, ET can begin much earlier in life, with a progressive disease course that can eventually necessitate a care partner. Social anxiety and depressive symptoms can manifest in patients with ET as tremor severity increases and may negatively impact a patient’s ability to work and engage in hobbies. The only U.S. Food and Drug Administration (FDA) approved pharmacological treatment for ET was approved more than 50 years ago, and more than 50% of patients with ET experience a sub-optimal response with standard-of-care treatments, highlighting a significant unmet need in care.

About SAGE-324

SAGE-324 is an investigational oral neuroactive steroid (NAS) GABAA receptor positive allosteric modulator (PAM). NAS GABAA receptor PAMs bind to both synaptic and extrasynaptic GABAA receptors, enhancing inhibitory activity of the GABAergic system, the major inhibitory neurotransmission system in the brain. GABA is the primary inhibitory neurotransmitter in the central nervous system and plays a critical role in maintaining balanced neuronal activity in the brain. GABA dysregulation has been implicated in the pathophysiology of ET.
