(NASDAQ: PHIO) is a clinical-stage biotechnology company focused on developing immuno-oncology therapies. The company’s research centers on RNA interference (RNAi), a biological process that can reduce the production of specific proteins involved in disease. Phio is developing treatments intended to activate and enhance the body’s immune response against cancer. The company’s proprietary INTASYL™ platform is designed to deliver small interfering RNA (siRNA) directly into cells without requiring traditional delivery vehicles. Phio has used the platform to develop investigational compounds that target immune-regulating proteins. Its lead program, PH-762, is designed to inhibit PD-1 in immune cells and is being studied as a potential treatment for solid tumors and other cancers. The company has also advanced additional preclinical and clinical-stage programs, including compounds directed at other targets relevant to tumor immunity. Phio Pharmaceuticals was formerly known as RXi Pharmaceuticals and adopted its current name in 2018 to reflect its focus on the INTASYL platform and immuno-oncology. The company is headquartered in Marlborough, Massachusetts, and primarily conducts research and clinical development activities in the United States. Its products remain investigational and are not approved for commercial sale.AI Generated. May Contain Errors.
