CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Syros Pharmaceuticals (NASDAQ: SYRS), a biopharmaceutical company pioneering the development of medicines to control the expression of genes, today announced that the U.S. Patent and Trademark Office has issued two patents covering methods for stratifying patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) for treatment with SY-1425 (tamibarotene), the Company’s first-in-class selective retinoic acid receptor alpha (RARα) agonist.

The first patent, U.S. Patent 9,845,508, covers a method of diagnosing and treating AML patients by determining whether they have elevated levels of RARA messenger RNA (mRNA) and, if they do, administering SY-1425. The second patent, U.S. Patent 9,868,994, covers a method of treating AML and MDS by administering SY-1425 to patients known to have elevated levels of IRF8 mRNA. For purposes of these patents, AML does not include acute promyelocytic leukemia, or APL.

Using its gene control platform, Syros identified subsets of AML and MDS patients with a highly specialized regulatory region of DNA, known as a super-enhancer, associated with either the RARA or IRF8 gene, or both. The Company is using a clinical trial assay to identify AML and MDS patients with elevated levels of RARA and IRF8 mRNA for inclusion in a Phase 2 clinical trial assessing the safety and efficacy of SY-1425 in combination with azacitidine, a hypomethylating agent, and in combination with daratumumab, an anti-CD38 therapeutic antibody.

Syros continues to prosecute additional patent applications generally covering methods of stratifying patients for treatment with RARα agonists. The Company believes that each of its recently issued U.S. patents are eligible for listing in the U.S. Food and Drug Administration’s Orange Book and would expire no earlier than 2036.

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.
