Syros Announces Publication in Cell Highlighting Gene Control as Important and Rapidly Progressing Area of Research for Yielding New Medicines to Treat Cancer

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Feb. 9, 2017-- Syros Pharmaceuticals (NASDAQ:SYRS) today announced the publication of a paper in a special cancer-focused issue of the scientific journal Cell that highlights gene control as an important area for cancer drug discovery and development, underscoring the promise of Syros’ pioneering approach to advance a new wave of medicines that control the expression of disease-driving genes.

The paper, which was co-authored by two of Syros’ scientific founders James E. Bradner, M.D., and Richard Young, Ph.D., focuses on abnormal transcription, the process by which genes are expressed and produce proteins, as a fundamental driver of cancer. Many aggressive cancers are dependent on an unusually high and constant level of transcription of otherwise normal genes to fuel their development and growth, a phenomenon known as transcriptional addiction. Because targeted cancer drug discovery to date has focused on identifying genetic mutations, existing genomic-based approaches fail to detect these transcriptional addictions, which can potentially be exploited to thwart cancer’s growth. The paper points to transcription factors and transcriptional kinases as attractive drug targets for controlling the abnormal expression of genes because of their key role in transcription.1

“The inclusion of this paper in this special issue of Cell shows that gene control is gaining the attention of leaders in the scientific community as an important area for drug discovery and development,” said Eric Olson, Ph.D., Syros’ Chief Scientific Officer. “Syros is a pioneer in gene control, and a key focus of our platform is understanding and drugging transcriptional targets to control the expression of the critical set of genes driving a disease. By creating small molecules to modulate these historically difficult-to-drug targets, we believe we can provide a meaningful benefit for patients with a wide range of diseases that have eluded other genomic-based approaches.”

Syros has built the first proprietary platform to systematically and efficiently identify disease-causing alterations in gene expression and create medicines to selectively target transcription to control the expression of genes with the aim of treating cancer, as well as autoimmune and rare genetic diseases. Because gene expression is fundamental to the function of all cells, the Company’s platform has broad potential applicability across a range of diseases and therapeutic areas.

Using its platform, Syros is advancing a growing pipeline of gene control drug candidates. The Company’s lead drug candidate, SY-1425, is an oral first-in-class selective agonist of retinoic acid receptor alpha (RARα) in a Phase 2 clinical trial in defined subsets of acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) patients whose disease is driven by the over-expression of RARA, the gene that produces the RARα transcription factor. Syros’ second most advanced program is SY-1365, a first-in-class selective inhibitor of cyclin-dependent kinase 7 (CDK7), which has been shown in preclinical studies to lower the expression of cancer-driving transcription factors in a range of transcriptionally addicted solid tumors and blood cancers. SY-1365 is on track to begin a Phase 1 clinical trial in the first half of this year in patients with transcriptionally driven solid tumors, including triple negative breast, small cell lung and ovarian cancers.

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.
