Initial Clinical Data on SY-1425 as Single Agent from Relapsed or Refractory AML and Higher-Risk MDS and Lower-Risk MDS Cohorts in Phase 2 Trial to be Presented at ASH

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Syros Pharmaceuticals (NASDAQ: SYRS), a biopharmaceutical company pioneering the discovery and development of medicines to control the expression of disease-driving genes, today reported financial results for the quarter ended September 30, 2017 and provided an update on recent accomplishments and upcoming events.

“Syros made significant progress in the third quarter, driving toward an initial clinical data readout at ASH from our ongoing Phase 2 clinical trial of SY-1425 as well as adding a combination arm with SY-1425 and an anti-CD38 therapy to the trial, and continuing to execute efficiently on the dose escalation phase of our Phase 1 trial of SY-1365,” said Nancy Simonian, M.D., Chief Executive Officer of Syros. “We presented key data on both programs, showing favorable PK and evidence of target engagement in patients from the clinical trial of SY-1425, as well as a significant correlation between the biomarker status of patients screened for the trial and differentiation of their cells treated ex vivo with SY-1425, supporting our platform’s ability to identify patients we believe may be most likely to respond to gene control therapies such as SY-1425. For SY-1365, we presented PK and PD data showing substantial anti-tumor activity in preclinical models of multiple cancers using a twice weekly dose consistent with the initial dosing regimen being used in the Phase 1 trial. We are at an exciting time in the company’s evolution, with multiple clinical data readouts for SY-1425 and SY-1365 expected between now and the end of 2018, a rich preclinical pipeline, and a leading gene control platform that we believe will continue to fuel our pipeline and fulfill our mission of improving patients’ lives.”

Upcoming Milestones

• Syros plans to report initial clinical data from the relapsed or refractory acute myeloid leukemia (AML) and higher-risk myelodysplastic syndrome (MDS) cohort, as well as the lower-risk transfusion-dependent MDS cohort, in its ongoing Phase 2 clinical trial of SY-1425, an oral first-in-class selective retinoic acid receptor alpha (RARα) agonist, at the 59^th American Society of Hematology (ASH) Annual Meeting and Exposition on Sunday, December 10, 2017. The presentation will include data on evidence of differentiation in patients’ bone marrow and initial assessments of clinical activity and safety of SY-1425 as a single agent. The Phase 2 trial is evaluating the safety and efficacy of SY-1425 as a single agent in four AML and MDS patient populations, as well as in combination with azacitidine in newly diagnosed AML patients who are not suitable candidates for standard chemotherapy. Syros recently amended the protocol of this trial to add a cohort evaluating the safety and efficacy of SY-1425 in combination with an anti-CD38 therapy in patients with relapsed or refractory AML or higher-risk MDS. The Company expects to begin enrolling patients in this cohort in early 2018. All patients enrolled or to be enrolled in the trial are prospectively selected using the Company’s RARA and IRF8 biomarkers.
• Syros expects to present additional clinical data from the ongoing Phase 2 trial, including data assessing the safety and efficacy of SY-1425 in combination with azacitidine and with an anti-CD38 antibody, in 2018.
• Syros plans to present new preclinical data at ASH showing significant anti-tumor activity of SY-1365, a first-in-class selective cyclin-dependent kinase 7 (CDK7) inhibitor, in multiple leukemia and lymphoma cell lines, as well as in vivo models of AML. The Company also plans to present preclinical data at ASH on its identification of a biomarker related to the mitochondrial apoptosis pathway that is predictive of sensitivity to SY-1365 in leukemia cell lines, as well as in vitro data showing synergy with the BCL2 inhibitor venetoclax.
• Syros expects to report initial clinical data from its ongoing Phase 1 trial of SY-1365 in patients with advanced solid tumors in 2018.

Recent Platform and Pipeline Highlights

• In October 2017, Syros presented preclinical PK and PD data on SY-1365 at the 2017 AACR-NCI-EORTC Molecular Targets and Cancer Therapeutics Conference. The data showed that SY-1365 has a prolonged PD effect and induces sustained tumor regressions in multiple preclinical models using intermittent dosing, supporting the twice weekly dosing regimen currently being used in the Phase 1 trial in patients with advanced solid tumors.
• In October 2017, Syros announced a publication co-authored by two of its scientific founders, Nathanael S. Gray, Ph.D., and Richard A. Young, Ph.D., in the peer-reviewed scientific journal Cancer Discovery that highlighted CDK7 inhibition in combination with targeted therapies as a promising new approach for combatting drug resistance. In multiple in vitro and in vivo models of treatment-resistant cancers, CDK7 inhibition enhanced tumor cell killing and impeded the emergence of drug-resistant cell populations when combined with targeted therapies, including MEK, BRAF, EGFR and ALK inhibitors, compared to either a CDK7 inhibitor or the targeted therapy alone.
• In October 2017, Syros’ drug discovery research in immuno-oncology was highlighted in an oral presentation at the American College of Surgeons 2017 Clinical Congress. As part of a research collaboration with the Lowy laboratory at the University of California San Diego Moores Cancer Center, Syros scientists identified alterations in regulatory regions of the genome in immune, tumor and stromal cells isolated from pancreatic cancer patient tumors. The goal of the Company’s immuno-oncology program is to discover and develop new drugs with the potential to reactivate the immune system to fight cancer.
• In October 2017, Syros presented biomarker data from its ongoing Phase 2 clinical trial of SY-1425 at the European School of Haematology’s 4^th International Conference on Acute Myeloid Leukemia “Molecular and Translational”: Advances in Biology and Treatment. The data showed that the biomarker status of patients screened for the trial was predictive of myeloid cell differentiation in the patients’ blood samples treated ex vivo with SY-1425, supporting the potential clinical utility of the Company’s biomarkers for patient selection. Data also showed that SY-1425 robustly induced CD38 in an in vivo model of biomarker positive AML. Syros also announced that approximately 40% of the 201 evaluable patients screened for the clinical trial through August were biomarker-positive, including one-third of relapsed or refractory AML and higher-risk MDS patients.
• In September 2017, Syros presented PK and PD data from its ongoing Phase 2 clinical trial of SY-1425 at the European Society of Medical Oncology (ESMO) 2017 Congress. The data showed that the dosing regimen being used in the trial achieves blood levels sufficient to elicit a PD response with evidence of RARα target engagement. Data also showed no significant accumulation or reduction in drug exposure after two weeks of continuous dosing, demonstrating favorable PK properties compared to historical data with ATRA, a non-selective retinoic acid receptor agonist. Syros also presented the design of its ongoing Phase 1 trial for SY-1365 at ESMO.
• In August 2017, Syros announced that the U.S. Food and Drug Administration granted orphan drug designation to SY-1425 for the treatment of AML. Orphan drug designation may provide certain benefits, including a seven-year period of market exclusivity if the drug is approved, tax credits for qualified clinical trials and an exemption from FDA application fees.

Third Quarter 2017 Financial Results

Cash, cash equivalents and marketable securities as of September 30, 2017 were $81.9 million, compared with $83.6 million on December 31, 2016. The decrease in cash, cash equivalents and marketable securities is primarily due to cash used to fund operations during the nine-months ended September 30, 2017, partially offset by gross proceeds of approximately $35.0 million from Syros’ April 2017 private placement.

For the third quarter of 2017, Syros reported a net loss of $13.8 million, or $0.53 per share, compared to a net loss of $14.2 million, or $0.65 per share, for the same period in 2016. Stock-based compensation included in the net loss was $1.1 million for the third quarter of 2017, compared to $1.7 million for the same period in 2016.

• Research and development (R&D) expenses were $10.4 million for the third quarter of 2017, as compared to $11.6 million for the same period in 2016. This decrease was primarily attributable to a $1.0 million milestone payment paid to TMRC Co., Ltd. in September 2016 upon the first dosing of a patient in the Phase 2 clinical trial of SY-1425 for which no comparable payment was made in 2017, a decrease in costs from third parties that conduct research and development and preclinical activities on the Company’s behalf that are primarily due to the completion of GLP toxicology studies for SY-1365 in 2016, and a decrease in stock-based compensation. These decreases were partially offset by increases in discovery expenses. Stock-based compensation included in R&D expenses was $0.4 million for the third quarter of 2017, compared to $1.2 million for the same period in 2016.
• General and administrative (G&A) expenses were $3.6 million for the third quarter of 2017, as compared to $2.6 million for the same period in 2016. This increase was primarily attributable to an increase in employee-related costs, including salary, benefits and stock-based compensation. Stock-based compensation included in G&A expenses was $0.7 million for the third quarter of 2017, compared to $0.5 million for the same period in 2016.

Financial Guidance

Syros expects that its operating expenses for 2017 will be approximately $55.0 million. This amount includes approximately $5.0 million in non-cash expenses, primarily consisting of stock-based compensation and depreciation, resulting in an estimated cash burn of approximately $50.0 million for the year.
