VANCOUVER, Feb. 21, 2018 /PRNewswire/ - Sierra Oncology, Inc. (Nasdaq: SRRA), a clinical stage drug development company focused on advancing next generation DNA Damage Response (DDR) therapeutics for the treatment of patients with cancer, today announced it has been accepted to present preclinical data demonstrating that its Chk1 inhibitor, SRA737, synergizes with niraparib, a poly ADP-ribose inhibitor (PARPi), in a poster at the American Association of Cancer Research (AACR) Annual Meeting 2018 being held in Chicago, Illinois from April 14-18.

"There is a strong biological rationale for synergy between SRA737 and PARP inhibition, which is further validated by these data. Notably, this combination was effective in homologous repair proficient tumor cell lines where PARP inhibitors are substantially less active in the clinical setting," said Dr. Christian Hassig, Chief Scientific Officer of Sierra Oncology. "Sierra is designing a potential clinical study to evaluate SRA737 in combination with a PARP inhibitor, including evaluation in comparable patient populations."

About Sierra OncologySierra Oncology is a clinical stage drug development company advancing next generation DNA Damage Response (DDR) therapeutics for the treatment of patients with cancer. Our lead drug candidate, SRA737, is a potent, highly selective, orally bioavailable small molecule inhibitor of Checkpoint kinase 1 (Chk1), currently being investigated in two Phase 1 clinical trials in patients with advanced cancer. Sierra Oncology is also advancing SRA141, a potent, selective, orally bioavailable small molecule inhibitor of Cell division cycle 7 kinase (Cdc7) undergoing preclinical development. Cdc7 is a key regulator of DNA replication and is involved in the DDR network, making it a compelling emerging target for the potential treatment of a broad range of tumor types.
