Syros Announces Presentation of New Preclinical Data on SY-1365 in Treatment-Resistant HR-Positive Breast Cancer Cell Lines at San Antonio Breast Cancer Symposium

CAMBRIDGE, Mass.--()--Syros Pharmaceuticals (NASDAQ: SYRS), a leader in the development of medicines that control the expression of genes, today announced that new preclinical data on SY-1365, its first-in-class selective cyclin-dependent kinase 7 (CDK7) inhibitor, will be featured in a Spotlight poster discussion session at the San Antonio Breast Cancer Symposium taking place December 4-8 in San Antonio. The data show that SY-1365 has dose-dependent inhibitory activity in hormone receptor-positive breast cancer cell lines that are resistant to treatment with CDK4/6 inhibitors.

The abstract for this presentation is now available online on the SABCS website at https://www.sabcs.org.

Details on the presentation are as follows:

About Syros Pharmaceuticals
Syros is pioneering the understanding of the non-coding regulatory region of the genome to advance a new wave of medicines that control the expression of genes. Syros has built a proprietary platform that is designed to systematically and efficiently analyze this unexploited region of DNA 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 ovarian and breast cancers. Syros is also developing a deep preclinical and discovery pipeline, including SY-5609, an oral CDK7 inhibitor, as well as programs in immuno-oncology and sickle cell disease. Led by a team with deep experience in drug discovery, development and commercialization, Syros is located in Cambridge, Mass.
