Its approach, known as translation control, is designed to interfere with the mechanisms cancer cells use to produce proteins needed for growth, survival and resistance to treatment. The company’s investigational pipeline has included zotatifin (eFT226), an inhibitor of the eukaryotic initiation factor 4A (eIF4A), and tomivosertib (eFT508), an inhibitor of mitogen-activated protein kinase-interacting kinases 1 and 2 (MNK1/2). These programs have been studied as potential treatments for solid tumors and other cancers, both as standalone therapies and in combination with existing treatments. Founded in 2012 and headquartered in San Diego, California, eFFECTOR has operated primarily as a research and development company serving the oncology biopharmaceutical market. The company was led by co-founder Steven A. Worland, who has served as president and chief executive officer. Its therapies remain investigational and are subject to clinical development and regulatory review. AI Generated. May Contain Errors.
