Syros Reports First Quarter 2018 Financial Results and Highlights Key Accomplishments and Upcoming Milestones

“Our priorities for 2018 are advancing our first-in-class drug candidates SY-1425 and SY-1365, leveraging our leading gene control platform to continue fueling our pipeline, and building on our strong financial position and company fundamentals,” said Nancy Simonian, M.D., Chief Executive Officer of Syros. “We have made terrific progress on all three fronts this year, presenting preclinical data that support the planned expansion of our Phase 1 trial of SY-1365 into ovarian cancer, entering into a collaboration with Incyte that applies our platform to diseases beyond our current areas of focus, and fortifying our financial position with a successful public offering. We continue to build momentum as we prepare for our planned data readouts in the fourth quarter of this year for both SY-1425 and SY-1365, and we remain focused on executing with excellence as we strive to build a great and enduring company with medicines that make a profound difference for currently underserved patients.”

Upcoming Milestones

• Syros plans to report initial clinical data in the fourth quarter of 2018 from cohorts in its Phase 2 trial evaluating SY-1425 in combination with azacitidine in RARA and IRF8 biomarker-positive newly diagnosed acute myeloid leukemia (AML) patients who are not suitable candidates for standard chemotherapy, and in combination with daratumumab in biomarker-positive relapsed or refractory AML and higher-risk myelodysplastic syndrome (MDS) patients. The primary objective of the trial is to evaluate the safety and efficacy of these combinations in biomarker-positive AML and higher-risk MDS patients. The Company announced today that it plans to add approximately 25 biomarker-negative newly diagnosed AML patients who are not suitable candidates for standard chemotherapy to its ongoing Phase 2 trial in order to support the development of a commercial companion diagnostic test for SY-1425. These patients will be treated with SY-1425 in combination with azacitidine.
• Syros plans to open expansion cohorts in mid-2018 in its ongoing Phase 1 trial of SY-1365 in multiple patient populations with ovarian and breast cancer to evaluate SY-1365 as a single agent and in combination with standard-of-care therapies.
• Syros plans to report clinical data in the fourth quarter of 2018 from the dose escalation portion of its ongoing Phase 1 trial of SY-1365 in advanced solid tumor patients.
• Syros plans to select a new development candidate from its preclinical pipeline by the end of 2018.

Recent Platform and Pipeline Highlights

• In April 2018, Syros and its collaborators at the Dana-Farber Cancer Institute presented new preclinical data on SY-1365 at the American Association for Cancer Research (AACR) Annual Meeting in Chicago. SY-1365 demonstrated potent anti-tumor activity in multiple models of heavily pretreated ovarian cancer, inhibiting tumor growth in 10 of the 17 patient-derived xenograft models studied, including inducing complete regressions. These responses were observed irrespective of BRCA status or sensitivity to a PARP inhibitor. Preclinical studies also pointed to potential biomarkers of response to SY-1365.

First Quarter 2018 Financial Results

Cash, cash equivalents and marketable securities as of March 31, 2018 were $121.7 million, compared with $72.0 million on December 31, 2017. This increase in cash reflects aggregate gross proceeds of approximately $46.0 million from Syros’ underwritten public offering of common stock that closed in February 2018, $1.4 million in proceeds from a private placement of stock to Incyte Corporation concurrent with this public offering, and a $10.0 million upfront payment and $10.0 million in proceeds from the sale of Syros common stock received in January 2018 in connection with Syros’ entry into its collaboration with Incyte.

For the first quarter 2018, Syros reported a net loss of $14.5 million, or $0.48 per share, compared to a net loss of $11.5 million, or $0.49 per share, for the same period in 2017. Stock-based compensation included in the net loss was $1.7 million for the first quarter 2018, compared to $0.9 million for the same period in 2017.

• Revenues were $0.4 million for the first quarter of 2018, as compared to $1.1 million for the same period in 2017. Revenues in the first quarter of 2018 were earned under Syros’ collaboration with Incyte, compared to revenues in the first quarter of 2017, which were earned from a research agreement with a multinational pharmaceutical company.
• Research and development (R&D) expenses were $11.1 million for the first quarter of 2018, as compared to $9.6 million for the same period in 2017. This increase was primarily attributable to increased external research and development costs associated with Syros’ ongoing clinical trials. Stock-based compensation included in R&D expenses was $0.6 million for the first quarter 2018, compared to $0.3 million for the same period in 2017.
• General and administrative (G&A) expenses were $4.1 million for the first quarter of 2018, as compared to $3.1 million for the same period in 2017. This increase was primarily attributable to an increase in employee-related costs, including salary, benefits and stock-based compensation, as well as legal and professional fees associated with entry into Syros’ collaboration with Incyte. Stock-based compensation included in G&A expenses was $1.1 million for the first quarter 2018, compared to $0.6 million for the same period in 2017.

Financial Guidance

Based on its current plans, Syros believes that its existing cash, cash equivalents and marketable securities will be sufficient to enable it to fund its planned operating expenses and capital expenditure requirements into 2020.

About Syros Pharmaceuticals

Syros is pioneering the understanding of the non-coding region of the genome to advance a new wave of medicines that control expression of genes. Syros has built a proprietary platform that is designed to systematically and efficiently analyze this unexploited region of DNA in human disease tissue to identify and drug novel targets linked to genomically defined patient populations. Because gene expression is fundamental to the function of all cells, Syros’ gene control platform has broad potential to create medicines that achieve profound and durable benefit across a range of diseases. Syros is currently focused on cancer and monogenic diseases and is advancing a growing pipeline of gene control medicines. Syros’ lead drug candidates are SY-1425, a selective RARα agonist in a Phase 2 clinical trial for genomically defined subsets of patients with acute myeloid leukemia and myelodysplastic syndrome, and SY-1365, a selective CDK7 inhibitor in a Phase 1 clinical trial for patients with advanced solid tumors. Led by a team with deep experience in drug discovery, development and commercialization, Syros is located in Cambridge, Mass.
