Publication number: 20240141061Abstract: The present disclosure relates to an antibody binding specifically to CD55 or an antigen-binding fragment thereof; and a composition for preventing, treating and/or diagnosing cancer containing the same. The antibody of the present disclosure may be used as an effective therapeutic composition for various CD55-mediated diseases since it shows high binding ability and inhibitory effect for the CD55 protein which promotes tumor growth by inhibiting the complement immune mechanism. In addition, the antibody of the present disclosure may be usefully used as an effective therapeutic adjuvant that fundamentally removes drug resistance and remarkably improves therapeutic responsiveness in various diseases in which resistance to therapeutic agents with CDC (complement-dependent cytotoxicity) as a mechanism of action has been induced due to overexpression of CD55.Type: ApplicationFiled: January 12, 2022Publication date: May 2, 2024Applicants: SG MEDICAL INC, KOREA UNIVERSITY RESEARCH AND BUSINESS FOUNDATION, KOREA ATOMIC ENERGY RESEARCH INSTITUTEInventors: Ji Chul LEE, Hye In PARK, Sung-Won MIN, Sung-Won MIN, Hyeong Sun KWON, Jae Cheong LIM, So Hee DOH, Eun Ha CHO, So-Young LEE, Sung Hee JUNG
