Edgewood Oncology, a clinical-stage biotechnology company focused on delivering BTX-A51 to patients with hematologic malignancies and genetically-defined solid tumors, emerged from stealth with $20 million in Series A financing backed by Alta Partners to advance the clinical development of BTX-A51 in acute myeloid leukemia (AML) and a precision medicine approach to breast cancer. BTX-A51 is a first-in-class, small molecule, multi-kinase inhibitor of casein kinase 1 alpha (CK1α), cyclin-dependent kinase 7 (CDK7) and CDK9 that synergistically co-targets master regulators of cancer to promote programmed cell death, or apoptosis.
