Syndax Pharmaceuticals Reports Fourth Quarter 2018 Financial Results and Provides Clinical and Business Update
WALTHAM, Mass., March 7, 2019 /PRNewswire/ -- Syndax Pharmaceuticals, Inc. ("Syndax," the "Company" or "we") (Nasdaq: SNDX), a clinical stage biopharmaceutical company developing an innovative pipeline of cancer therapies, today reported its financial results for the fourth quarter ended December 31, 2018. In addition, the Company provided a clinical and business update. As of December 31, 2018, Syndax had $80.9 million in cash, cash equivalents and short-term investments.
"We expect the coming months to be a very exciting, milestone-rich time for Syndax as we continue to work towards our mission of realizing a future in which cancer patients live longer and better lives than previously possible," said Briggs W. Morrison, M.D., Chief Executive Officer of Syndax. "We remain highly encouraged by the potential for a positive overall survival readout in E2112, our Phase 3 registration trial of entinostat plus exemestane in HR+, HER2- breast cancer, and expect the next interim analysis in the second quarter. As a reminder, any positive overall survival result would allow us to file for full regulatory approval in an indication for which existing therapies have failed to show a survival benefit. In addition, we continue to expect to file an IND in the second quarter for our targeted therapy, SNDX-5613, an inhibitor of the Menin-MLL interaction. Preclinical data from our Menin inhibitor program has provided strong, consistent support for the therapeutic potential of this class in patients with genetically-defined acute leukemias, a disease area lacking effective options."
Syndax also today announced that both ENCORE 602, the Phase 1b/2 clinical trial evaluating the combination of entinostat plus Genentech's PD-(L)1 inhibitor, TECENTRIQ® (atezolizumab), in patients with triple negative breast cancer (TNBC), and ENCORE 603, the Phase 1b/2 trial evaluating entinostat in combination with BAVENCIO® (avelumab), an anti-PD-(L)1 co-developed and co-commercialized by Merck KGaA Darmstadt, Germany and Pfizer, in patients with ovarian cancer, failed to meet their respective primary endpoints of demonstrating an improvement in progression free survival (PFS).
With results across the entire ENCORE program now in hand, Syndax has decided to defer advancement of the entinostat-PD-1 combination program, including the previously announced ENCORE 607 registration trial in non-small cell lung cancer (NSCLC). Going forward, the Company will primarily focus its resources on advancing entinostat in HR+ breast cancer and SNDX-5613, a Menin inhibitor being developed for genetically-defined population of acute leukemias. Following availability of positive E2112 OS results, the Company will determine whether to advance its entinostat-PD-1 combination programs into one or more registration trials.
Dr. Morrison added, "While we are encouraged by ENCORE 601 entinostat-KEYTRUDA® combination data in NSCLC and melanoma which suggests that entinostat has the ability to overcome resistance in PD-1 refractory patients, we believe that it is in the best interest of our stakeholders to prioritize our resources ahead of the E2112 OS readout, at which time we will make a determination on next steps for the I-O combination program. We are highly committed to advancing the balance of our pipeline programs, with an emphasis on our targeted therapy, SNDX-5613, and the E2112 registrational trial for HR+ breast cancer."
- The Company continues to anticipate the next interim OS analysis for E2112, its NCI-sponsored, ECOG-ACRIN led Phase 3 registration trial of entinostat, a Class I selective HDAC inhibitor, plus exemestane in advanced hormone receptor positive, human epidermal growth factor receptor 2 negative (HR+, HER2-) breast cancer, in the second quarter of 2019. Additional interim analyses will be conducted by ECOG-ACRIN approximately every six months until either an OS benefit is observed, or the final target number of events occur. Any positive OS assessment would enable the Company to file for full regulatory approval. The E2112 trial design was informed by the Phase 2b ENCORE 301 trial, the results of which led to entinostat's Breakthrough Therapy designation in HR+, HER2- breast cancer, in which patients receiving the entinostat/exemestane combination demonstrated a statistically significant OS benefit.
- As previously announced, data from the NSCLC and melanoma cohorts of the ENCORE 601 trial will each be featured during oral presentations at the American Association of Cancer Research (AACR) Meeting later this month. Data to be presented will include the Company's most recent insights into the potential mechanisms that allow entinostat to enhance the benefit of immune checkpoint therapy.
- The Phase 1b/2 ENCORE 603 trial, which evaluated entinostat in combination with avelumab in patients with heavily pretreated advanced epithelial ovarian cancer, and the Phase 1b/2 ENCORE 602 trial, which evaluated entinostat in combination with atezolizumab in patients with PD-1 naïve, previously treated TNBC, each failed to meet its respective primary endpoint of a statistically significant improvement in PFS.
- Based on the activity observed to date, the Company has decided not to advance the ENCORE 601 cohort of patients with microsatellite stable colorectal cancer (MSS-CRC) to the second stage of the trial.
- Preclinical data supporting the Company's Menin-Mixed Lineage Leukemia (MLL) inhibitor program were presented during an oral session at the 60th American Society of Hematology (ASH) Annual Meeting in December 2018.
- The Company continues to expect to file an Investigational New Drug (IND) application with the U.S. Food and Drug Administration (FDA) for its Menin inhibitor, SNDX-5613, in the second quarter of 2019, with the initiation of a Phase 1 clinical trial in a defined subset of acute leukemias patients expected to follow.
- The Company continues to anticipate initial results from the Phase 1 dose escalation trial of SNDX-6352, the Company's anti-CSF-1R monoclonal antibody, in patients with chronic graft versus host disease (cGVHD) in the second half of the year. The objectives of this trial are to evaluate the safety and preliminary efficacy of SNDX-6352 in cGVHD and to identify a recommended Phase 2 dose and schedule.
- The Company continues to anticipate identifying a recommended Phase 2 dose and schedule for SNDX-6352 monotherapy and in combination with IMFINZI® (durvalumab), AstraZeneca's human monoclonal antibody directed against PD-L1, in the second quarter of 2019. The dose selections will be based on the results of the ongoing Phase 1/1b ascending dose trial evaluating the safety of SNDX-6352 alone or in combination with durvalumab.
Fourth Quarter 2018 Financial Results
As of December 31, 2018, Syndax had cash, cash equivalents and short-term investments of $80.9 million and 26.8 million shares issued and outstanding.
License fee revenue decreased to $0.4 million in the fourth quarter 2018 from $1.2 million for the prior year fourth quarter, and for 2018 decreased to $1.5 million compared to $2.1 million for the prior year. The decreases are due to the ratable recognition of a $5.0 million payment from KHK for the achievement of a development milestone in the fourth quarter of 2017.
Fourth quarter 2018 research and development expenses decreased to $15.8 million from $16.6 million, and for the full year increased to $60.1 million compared to $48.2 million for 2017. The fourth quarter decrease was primarily due to expensing a payment of $5.0 million to Allergan to acquire SNDX-5613 in the fourth quarter of 2017, offset by an increase in SNDX-6352 manufacturing expenses. The increase for the full year was primarily due to increased expenses for SNDX-6352 manufacturing, SNDX-5613 program expenses and increased headcount, offset by the payment of $5.0 million to Allergan in 2017.
General and administrative expenses for the fourth quarter 2018 decreased to $3.9 million from $4.1 million, and, for the year ended December 31, 2018 increased to $17.3 million compared to $15.9 million for the prior year. The full year increase was primarily due to increased pre-commercialization expenses.
For the three months ended December 31, 2018, Syndax reported a net loss attributable to common stockholders of $18.8 million or $0.70 per share compared to $19.1 million or $0.80 per share for the prior year period. For the year ended December 31, 2018, Syndax reported a net loss attributable to common stockholders of $74.0 million or $2.92 per share, compared to $60.8 million or $2.90 per share for the prior year.
Today the Company provided operating expense guidance for the first quarter and full year 2019. For the first quarter and full year 2019, research and development expenses are expected to be $11 to $13 million and $46 to $50 million, respectively, and total operating expenses are expected to be $15 to $17 million and $60 to $64 million, respectively.
