Sierra Oncology is a clinical stage drug development company advancing targeted therapeutics for the treatment of patients with unmet medical needs in hematology and oncology. Our lead drug candidate, momelotinib, is a potent, selective and orally-bioavailable JAK1, JAK2 & ACVR1 inhibitor with a differentiated therapeutic profile in myelofibrosis encompassing a range of meaningful anemia benefits, including eliminating or reducing the need for frequent blood transfusions, as well as achieving substantive spleen and constitutional symptom control. We are also advancing SRA737 and SRA141. SRA737, is a potent, highly selective, orally bioavailable small molecule inhibitor of Checkpoint kinase 1 (Chk1). We are ...

Sierra Oncology is a clinical stage drug development company advancing targeted therapeutics for the treatment of patients with unmet medical needs in hematology and oncology. Our lead drug candidate, momelotinib, is a potent, selective and orally-bioavailable JAK1, JAK2 & ACVR1 inhibitor with a differentiated therapeutic profile in myelofibrosis encompassing a range of meaningful anemia benefits, including eliminating or reducing the need for frequent blood transfusions, as well as achieving substantive spleen and constitutional symptom control. We are also advancing SRA737 and SRA141. SRA737, is a potent, highly selective, orally bioavailable small molecule inhibitor of Checkpoint kinase 1 (Chk1). We are pursuing an innovative development plan for SRA737, which is currently being evaluated in two Phase 1/2 clinical trials in patients with advanced cancer. SRA737-01 is intended to evaluate SRA737`s potential to induce synthetic lethality as monotherapy, while SRA737-02 is intended to evaluate the combination of SRA737 potentiated by subtherapeutic, low dose gemcitabine. Concurrently, we are conducting preclinical research evaluating SRA737 in combination with other DDR-targeted agents, including PARP inhibitors, as well as with immuno-oncology therapeutics, that may guide a potential next wave of clinical development for our asset, possibly further broadening its therapeutic utility. SRA141, a potent, selective, orally bioavailable small molecule inhibitor of cell division cycle 7 kinase (Cdc7). Cdc7 is a key regulator of DNA replication and is involved in the DDR network, making it a compelling emerging target for potential treatment across a broad range of tumor types. An Investigational New Drug Application (IND) submission to the U.S. Food and Drug Administration (FDA) is being prepared in order to commence clinical trials with this drug candidate.
