SRB5 is a humanized monoclonal antibody with enhanced ADCC properties, designed to selectively deplete CCR9+ cells involved in chronic intestinal inflammation. It is the latest advancement in SunRock’s anti-CCR9 platform and represents a significant advance in a selective therapeutic approach for treating diseases such as Crohn’s disease and ulcerative colitis. Through this partnership, SunRock will benefit from Chime Biologics’ global-standard GMP manufacturing platform to scale production and accelerate preclinical and regulatory milestones.
“We are proud to collaborate with SunRock Biopharma on this promising anti-CCR9 antibody (SRB5) for inflammatory bowel disease, a condition that significantly impacts patients worldwide. This partnership reflects our commitment to applying our global-standard quality and comprehensive experiences in manufacturing biologics to accelerate the development of innovative therapies. We look forward to contributing to the long-term mission of SunRock Biopharma to develop innovative antibodies against highly invasive tumors with an urgent clinical need in oncology,” said Dr.Jimmy Wei, President of Chime Biologics.
Dr. Laureano Simón, CEO of SunRock Biopharma, added “This collaboration with Chime Biologics reinforces our strategy of working with world-class partners across every stage of development. Chime’s technical expertise and industrial quality standards will help us scale SRB5 under optimal conditions. SRB5 has a distinctive biological profile that could transform the therapeutic landscape in IBD and potentially in highly aggressive CCR9-expressing tumors. This agreement is a critical step toward clinical validation.”
