SunRock Biopharma and Chime Biologics Announce Strategic Collaboration to Advance Development of Anti-CCR9 Antibody SRB5<\/strong><\/h1>\n

\"\"<\/p>\n

October 21<\/b><\/strong>, 2025<\/b><\/strong>, <\/b><\/strong>Santiago de Compostela, Spain and Wuhan, China <\/b><\/strong>\u2013\u00a0SunRock Biopharma, a biotechnology company focused on developing next-generation therapeutic antibodies, and Chime Biologics,\u00a0a leading global CDMO that enables its partners' success in biologics, today announced a strategic collaboration for the development of SRB5, a novel anti-CCR9 monoclonal antibody targeting inflammatory bowel disease (IBD), with potential expansion into other immune-mediated inflammatory indications.<\/p>\n

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\u2019s anti-CCR9 platform and represents a significant advance in a selective therapeutic approach for treating diseases such as Crohn\u2019s disease and ulcerative colitis. Through this partnership, SunRock will benefit from Chime Biologics\u2019 global-standard GMP manufacturing platform to scale production and accelerate preclinical and regulatory milestones.<\/p>\n

\u201cWe 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,\u201d said Dr.<\/b><\/strong>\u00a0Jimmy Wei<\/b><\/strong>, President of Chime Biologics<\/b><\/strong>.<\/p>\n

Dr. Laureano Sim\u00f3n, CEO of<\/b><\/strong>\u00a0SunRock Biopharma<\/b><\/strong>, added \u201cThis collaboration with Chime Biologics reinforces our strategy of working with world-class partners across every stage of development. Chime\u2019s 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.\u201d<\/p>\n
