Syros Pharmaceuticals (NASDAQ:SYRS), a leader in the development of medicines that control the expression of genes, today announced that it will present new data from the dose-escalation portion of the Phase 1 clinical trial of SY-5609, its highly selective and potent oral cyclin-dependent kinase 7 (CDK7) inhibitor, at the ESMO Congress 2021, taking place virtually September 16-21, 2021. The oral presentation will include safety, tolerability, and initial clinical activity data for SY-5609 in patients with breast, colorectal, lung, ovarian and pancreatic cancers, as well as in patients with solid tumors of any histology harboring Rb pathway alterations.
In separate poster presentations, Syros will present new preclinical data evaluating the antitumor and pharmacodynamic activity of intermittent dosing regimens for SY-5609 in ovarian cancer models, as well as new preclinical data evaluating antitumor activity of SY-5609 as a single agent and in combination with chemotherapy in KRAS-mutant models.
The abstracts for the two poster presentations are now available online on the ESMO conference website at: https://www.esmo.org/meetings/esmo-congress-2021/abstracts, and the presentations will become available for on-demand viewing starting September 16 at 08:30 CEST (September 16 at 2:30 a.m. ET).
