RQ Bio
RQ Bio is a biotechnology company that develops long-acting monoclonal antibodies against seasonal influenza with the goal of providing immediate, powerful, and long-lasting protection against severe viral disease in immunocompromised and high-risk subjects. The company's mission is to deliver "instant immunity" through passive immunization, helping protect vulnerable populations such as the elderly, newborns, and immunocompromised patients from severe infectious diseases. The company specializes in the discovery and development of broad-spectrum antiviral antibodies that are engineered to remain effective even as viruses evolve. Its scientific approach combines virology, antibody engineering, computational biology, and immune-directed discovery techniques to identify potent antibodies that target conserved regions of viral proteins, reducing the risk of resistance caused by viral mutations. RQ Bio's lead programs focus on infectious diseases such as influenza, COVID-19, respiratory syncytial virus (RSV), and cytomegalovirus (CMV). The company is currently developing long-acting monoclonal antibodies designed to provide once-yearly protection against seasonal influenza, particularly for individuals at high risk of severe disease.
