2016 Accomplishments Put Company on Track to Achieve Significant 2017 Clinical Milestones

Initial Data Readout from Ongoing Phase 2 Clinical Trial of SY-1425, Its First-in-Class Selective RARα Agonist, in Subsets of AML and MDS Patients Expected in Fall of 2017

SY-1365, Its First-in-Class Selective CDK7 Inhibitor, Expected to Advance into Phase 1 Clinical Trial in First Half of 2017

Company Also Reveals New Preclinical Program

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Syros Pharmaceuticals (NASDAQ: SYRS), a biopharmaceutical company pioneering the development of medicines to control the expression of disease-driving genes, today outlined its strategic plan and goals, including expected research and development milestones, for 2017. The plan outlines three strategic priorities:

  • Aggressively advancing its two lead programs, SY-1425, a first-in-class selective retinoic acid receptor alpha (RARα) agonist in genomically defined subsets of acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), and SY-1365, a first-in-class potent and selective cyclin-dependent kinase 7 (CDK7) inhibitor in solid tumors and acute leukemias;
  • Enhancing and leveraging its proprietary gene control platform to further expand its pipeline in cancer, including immuno-oncology and rare cancers, and in autoimmune and rare genetic diseases; and
  • Building on the Company’s strong financial, leadership and cultural fundamentals.

“2016 was a year of tremendous progress as we transitioned Syros to a clinical-stage and publicly listed company and continued to build our research platform and organization,” said Nancy Simonian, M.D., chief executive officer of Syros. “These accomplishments lay the groundwork for a breakthrough 2017, putting us on track to achieve an initial data readout for our first clinical program, advance our second program into clinical development, and expand our preclinical pipeline. Reaching these milestones, together with the experience of our team and our leadership in the rapidly advancing science of Genomics 3.0, will bring us closer to our aspiration of providing a profound and durable benefit for patients with diseases that have eluded other genomic-based approaches.”

The Company’s key 2017 goals include:


  • Presenting initial clinical data in the fall of 2017 from the ongoing Phase 2 clinical trial in AML and MDS patients with a novel RARA biomarker discovered by Syros;
  • Initiating combination dosing in the ongoing Phase 2 trial to explore the safety and efficacy of SY-1425 when combined with azacitidine, a standard-of-care therapy, in newly diagnosed AML patients 60 years of age or older who are not suitable candidates for standard chemotherapy; and
  • Expanding clinical development into Europe.


  • Initiating a Phase 1 clinical trial in patients with transcriptionally driven solid tumors, including ovarian, triple negative breast and small cell lung cancers, in the first half of 2017.

Platform and Early-Stage Pipeline

  • Advancing at least one of the Company’s four preclinical programs to support an IND filing in 2019, keeping the Company on track to achieve its goal of filing at least one IND every other year; and
  • Applying its gene control platform to offer a new approach in rare cancers and genetic diseases.

Company Building

  • Establishing at least one strategic collaboration around its platform or programs; and
  • Managing cash-based operating expenses on a non-GAAP1 basis to approximately $50 million, allowing the Company to invest across its programs and platform in order to reach key value-driving milestones.

In addition to announcing its 2017 goals, Syros also revealed for the first time today that it has advanced an oral CDK7 inhibitor program into preclinical development.

The Company’s 2016 accomplishments also include:


  • Receiving IND clearance and initiating the Phase 2 clinical trial in relapsed or refractory AML and high-risk MDS patients with the RARA biomarker.
  • Expanding the Phase 2 trial to include newly diagnosed AML patients 60 years of age and older who are not suitable candidates for standard chemotherapy and lower-risk transfusion-dependent MDS patients, following approval of an Investigational Device Exemption (IDE) for a laboratory-based blood test to detect proprietary biomarkers discovered using the Company’s platform.


  • Successfully completing IND-enabling studies, including Good Laboratory Practice (GLP) toxicology studies.

Platform and Early-Stage Pipeline

  • Advancing four preclinical programs, including the oral CDK7 inhibitor program and a previously disclosed cyclin-dependent kinase 12/13 (CDK12/13) inhibitor program.
  • Validating multiple new drug targets in breast cancer, AML, immuno-oncology and lupus.
  • Generating novel biological insights for drug discovery by applying its platform in additional cancers, immuno-oncology, and autoimmune and neurological diseases.

Company Building

  • Raising $97.5 million in gross proceeds from a private financing and initial public offering.
  • Ending the year with more than $83 million in cash, cash equivalents and marketable securities2, which the Company believes will be sufficient to fund its operating expenses and capital expenditure requirements into mid-2018.
  • Building out the Company’s chemistry, drug development and immunology teams.
  • Strengthening the leadership team and board of directors.

“In just three years, we’ve grown from a research-driven startup to a clinical-stage company with multiple programs in the pipeline,” said Dr. Simonian. “What we’ve achieved is a testament to the power of our platform and the commitment of our team as we strive to advance a new wave of medicines that control the expression of disease-driving genes and continue to create value for patients, employees and shareholders.”

About Syros Pharmaceuticals

Syros Pharmaceuticals is pioneering the understanding of the non-coding region of the genome to advance a new wave of medicines that control expression of disease-driving 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 immune-mediated 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 with potential in a range of solid tumors and blood cancers. Led by a team with deep experience in drug discovery, development and commercialization, Syros is located in Cambridge, Mass.
