CAMBRIDGE, Mass.--(BUSINESS WIRE)--Sage Therapeutics, Inc. (NASDAQ: SAGE), a clinical-stage biopharmaceutical company developing novel medicines to treat life-altering central nervous system (CNS) disorders, today reported business highlights and financial results for the third quarter ended September 30, 2017.
“We are on the verge of important data readouts as we move into the last quarter of 2017, and as we continue to make progress in executing on our R&D strategy,” said Jeff Jonas, M.D., Chief Executive Officer of Sage. “Sage has focused on understanding the underlying mechanisms of CNS disorders and developing novel treatments that may address current treatment gaps. We are pleased that our open-label data in Parkinson’s disease and essential tremor demonstrate potential for further development. The upcoming months have the potential to be transformational for Sage as we seek to bring new treatments to patients impacted by life-altering CNS disorders.”
Sage is advancing a portfolio of novel CNS product candidates targeting the GABA and NMDA receptor systems. Dysfunction in these systems is known to be at the core of numerous psychiatric and neurological disorders. Sage is pursuing a data-driven approach to CNS drug development by employing efficient human proof-of-concept methodology studies both to uncover activity signals and to help understand future trial design, before investing in larger clinical programs.
“Enrollment in our Phase 3 PPD trials and in our Phase 2 placebo-controlled MDD study is complete, and we are excited by the potential opportunity to change patients’ options for treatment of these disorders,” said Steve Kanes, M.D., Ph.D., Chief Medical Officer of Sage. “In addition to data readouts in PPD and MDD, our Phase 2 open-label methodology studies in movement disorders allow us to follow clinical data and take a deliberate and disciplined approach to designing the next Phase 2 studies.”
Brexanolone in Postpartum Depression:
- Sage is currently developing brexanolone in a Phase 3 clinical program as an acute interventional treatment for postpartum depression (PPD), consisting of separate multi-center, double-blind, placebo-controlled, randomized trials in severe PPD patients (202B) and in moderate PPD patients (202C), collectively known as the Hummingbird Study.
- Sage recently completed enrollment in its Phase 3 Hummingbird clinical program, and currently expects top-line results from the Phase 3 clinical trials of brexanolone in PPD to be the company’s next data readout.
SAGE-217 in Major Depressive Disorder:
- Sage is currently conducting a multi-center, double-blind, placebo-controlled, randomized Phase 2 clinical trial of SAGE-217 in major depressive disorder (MDD).
- Sage recently completed enrollment in the study, and expects to report top-line results in 4Q 2017.
SAGE-217 in Postpartum Depression:
- Sage is currently conducting a multi-center, double-blind, placebo-controlled, randomized Phase 2 clinical trial of SAGE-217 in severe PPD.
- Completion of enrollment for the Phase 2 trial is expected in 4Q 2017 with top-line results expected in 1Q 2018.
SAGE-217 in Parkinson’s Disease:
- Sage today announced top-line results from an open-label Phase 2 clinical trial of SAGE-217 in patients with tremor-predominant Parkinson’s disease.
- Part B of the exploratory study evaluated SAGE-217 as an adjunctive treatment for seven days in 14 tremor-predominant Parkinson’s disease patients who were on stable doses of anti-Parkinsonian agents.
- SAGE-217 improved tremor symptoms, as assessed by the MDS-UPDRS - Part II/III tremor score, by a mean change of 7.7 points (40.0%) by Day 8 from a mean baseline score of 19.1 points, which was the primary efficacy endpoint in the Part B study.
- Additional secondary efficacy endpoints were consistent with the primary efficacy endpoint. SAGE-217 improved overall Parkinson’s disease motor symptoms, as assessed by the MDS-UPDRS Part III motor score, by a mean change of 18.6 points (36.3%) by Day 8 from a mean baseline score of 52.4 points.
- SAGE-217 also improved symptoms of sleep dysfunction in five patients with clear sleep dysfunction at baseline, as assessed by the Parkinson’s Disease Sleep Scale (PDSS-2) score, by a mean change of 12.2 points (41.2%) by Day 8 from a mean baseline score of 29.8 points.
- Administration of SAGE-217 in the evening was generally well-tolerated with no serious adverse events or discontinuations reported. The most common adverse events were dizziness, sedation, and somnolence, each occurring in two patients.
- Sage believes the results from this open-label Phase 2 trial support further clinical development, and that the data from this study will provide guidance on methodology, dosing, and design for a future placebo-controlled Phase 2 clinical trial in Parkinson’s disease.
SAGE-217 in Essential Tremor:
- Sage is currently conducting Part C of an exploratory Phase 2 clinical trial of SAGE-217 in essential tremor.
- Part A was an open-label trial with morning dosing of SAGE-217 for 7 days. Part A enrolled 16 patients diagnosed with essential tremor, defined as visible and persistent bilateral postural tremor and kinetic tremor, involving hands and forearms, with a duration greater than 5 years prior to screening. Part C is an open-label clinical trial that was initiated to study higher doses and extended evening dosing of SAGE-217. As a result of the change in design, enrollment in Parts A and B of the trial was discontinued prior to completion. The Part A data are summarized below.
- In Part A, SAGE-217 improved tremor symptoms, as assessed by the TETRAS upper limb combined kinetic score, by at least 30% on Day 7 in 8/12 patients (67%) who received SAGE-217 oral capsule in the study for 7 days, which was the pre-established success criteria for moving to the next part of the study.
- Administration of SAGE-217 in the morning was generally well-tolerated. The most common adverse events were somnolence, dizziness, and sedation. There were no serious adverse events reported in the 14 patients receiving SAGE-217 oral capsule. There was one serious adverse event (confusion) reported in one of the two patients who received oral solution.
- Top-line results from Part C of the SAGE-217 essential tremor study are expected in 4Q 2017.
- Sage is currently evaluating a series of novel GABAA receptor modulators in pre-clinical development, including SAGE-324, a novel, orally-active next-generation positive allosteric modulator of synaptic and extrasynaptic GABAA receptors.
- SAGE-324 is currently in IND-enabling studies, and is intended to be developed with a focus on orphan epilepsies and indications involving GABA hypofunction.
- Sage is also developing novel compounds that target the NMDA receptor. The first product candidate selected for development from this program is SAGE-718, a novel, oral, first-in-class oxysterol-based positive allosteric modulator of the NMDA receptor. 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.
- Sage today announced that it recently completed a Phase 1 single-ascending dose study of SAGE-718 in healthy volunteers. The primary objectives of the study were to assess the safety, tolerability, and pharmacokinetics of SAGE-718.
- SAGE-718 was well-tolerated with no serious adverse events reported in the single ascending dose study.
- SAGE-718 was administered as an oral solution in four double-blind placebo-controlled cohorts (randomized 6:2) enrolling a total of 32 healthy volunteers. The pharmacokinetics of SAGE-718 were highly predictable with low variability.
- Based on these results, Sage plans to initiate a Phase 1 multiple ascending dose trial along with further dose finding studies. Sage is also investigating the effects of SAGE-718 on pharmacodynamic biomarkers.
