Pipeline UpdateSage is advancing a portfolio of multiple, novel central nervous system (CNS) product candidates targeting the GABA A and NMDA receptor systems. Dysfunction in these systems are known to be at the core of numerous psychiatric and neurological disorders. Sage is employing an innovative development approach focused on indications where patient populations are easily identified, clinical endpoints are well-defined, and development pathways are feasible.
- SAGE-547: Sage is currently developing SAGE-547 in separate clinical programs for the treatment of SRSE and PPD:
- SRSE: Sage is enrolling the Phase 3 STATUS Trial, a global, randomized, double-blind, placebo-controlled trial, designed to evaluate the efficacy and safety of SAGE-547 as a treatment for SRSE.
- PPD: Based on positive results from the placebo-controlled 202A clinical trial in severe PPD, Sage expanded its development program evaluating SAGE-547 for PPD with the initiation of two additional multi-center, placebo-controlled trials, one of which is a dose-ranging study of SAGE-547 in severe PPD patients ( 202B) and the other is studying the efficacy of SAGE-547 in moderate PPD patients ( 202C). Both clinical trials are currently enrolling. In September, the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation to SAGE-547 for the treatment of PPD. Sage is currently in discussions with the FDA regarding the design of the program to support a possible New Drug Application (NDA) approval.
- SAGE-217: Sage plans to focus clinical development of SAGE-217, a novel, orally-active next generation GABA modulator, on both mood and movement disorders, with four Phase 2 clinical programs expected to begin by the end of 2016.
- Mood Disorders:
- PPD: Sage plans to initiate a Phase 2 clinical program for SAGE-217 in PPD based on positive results to date from the SAGE-547 PPD clinical program. The Phase 2a multi-center, double-blind, placebo-controlled, randomized trial will evaluate the efficacy, safety, tolerability, and pharmacokinetics of SAGE-217 in the treatment of patients with PPD.
- MDD: Sage plans to initiate a two-part Phase 2 clinical trial of SAGE-217 in MDD. Part A of the Phase 2 trial will be an open-label, proof-of-concept study which, if positive, may lead to a larger randomized, placebo-controlled Phase 2 trial.
- Movement Disorders:
- Essential tremor: Based on prior positive proof-of-concept data, Sage plans to initiate a Phase 2 clinical program for SAGE-217 in essential tremor. The Phase 2a multi-center, double-blind, placebo-controlled, randomized withdrawal trial will evaluate the efficacy, safety, tolerability, and pharmacokinetics of SAGE-217 in the treatment of patients with essential tremor.
- Parkinson's disease: Sage plans to initiate a two-part Phase 2 clinical trial of SAGE-217 in Parkinson's disease. Part A of the Phase 2 trial will be an open-label, proof-of-concept study which, if positive, may lead to a larger randomized, placebo-controlled Phase 2 trial.
- Other GABA Programs: Sage is currently evaluating a series of novel GABA modulators in pre-clinical development, including SAGE-105, SAGE-324 and SAGE-689. Sage is planning to initiate IND-enabling studies this year for a novel, orally active next generation GABA modulator, either SAGE-105 or SAGE-324, which is intended to be developed for GABA-related indications, such as orphan epilepsies.
- SAGE-718: Sage is also studying novel compounds that target the NMDA receptor. The lead NMDA product candidate is SAGE-718, a novel NMDA positive allosteric modulator, currently being tested in IND-enabling studies. Sage expects to initiate Phase 1 clinical development for SAGE-718 in 2017.

- Cash Position: Cash, cash equivalents and marketable securities as of September 30, 2016 were $431.3 million, compared with $186.8 million at December 31, 2015. The increase was primarily due to net proceeds of $189.2 million, after deducting commissions and underwriting discounts, from Sage's follow-on public offering completed in September 2016.
- R&D Expenses: Research and development expenses were $29.1 million, including $2.5 million of non-cash stock-based compensation expense, in the third quarter of 2016, compared to $17.5 million, including $1.5 million of non-cash stock-based compensation expense, for the same period of 2015. The increase in R&D expense was primarily due to the ongoing clinical development of SAGE-547 in SRSE and PPD, completion of Phase 1 development for SAGE-217 and preparation for initiation of the Phase 2 clinical programs, the ongoing IND-enabling studies for SAGE-718 and investments in R&D headcount to support the growth in Sage's pipeline and operations.
- G&A Expenses: General and administrative expenses were $9.0 million, including $2.2 million of non-cash stock-based compensation expense, in the third quarter of 2016, compared to $6.6 million, including $2.9 million of non-cash stock-based compensation expense, for the same period of 2015. The increase in G&A expenses was primarily due to the increase in personnel-related expenses and professional fees to support expanding operations, as well as early commercial planning.
- Net Loss: Net loss was $37.8 million for the third quarter of 2016 compared to net loss of $24.0 million for the same period of 2015.
- Financial Guidance: Sage expects that its existing cash, cash equivalents and marketable securities will fund operating expenses and capital expenditure requirements, based on its current operating plan, into the second quarter of 2018.
