NORTH CHICAGO, Ill., and SHANGHAI, Sept. 4, 2020 /PRNewswire/ -- AbbVie (NYSE:ABBV) and I-Mab (NASDAQ:IMAB) announced today that AbbVie and I-Mab have signed a broad, global collaboration agreement for the development and commercialization of lemzoparlimab (also known as TJC4), an innovative anti-CD47 monoclonal antibody internally discovered and developed by I-Mab for the treatment of multiple cancers. In addition, the two partners have the potential to expand the collaboration to additional transformative therapies. 

Lemzoparlimab is one of the leading drug candidates among I-Mab's proprietary and innovative pipeline. It is designed to minimize inherent binding to normal red blood cells while preserving its strong anti-tumor activity, a critical attribute in potentially differentiating lemzoparlimab from other antibodies of the same class currently in development. Topline results of the recent phase 1 clinical trial confirm possible differentiation of lemzoparlimab in drug safety and a more favorable pharmacokinetics profile in cancer patients. Results have shown that lemzoparlimab is well tolerated as a single agent at a dose range of up to 30 mg/kg without any priming dose. In all DLT-evaluable patients, no dose-limiting toxicities or severe hematologic adverse events were observed. Full data will be presented at an appropriate scientific conference later this year.

"Cancer is the second-leading cause of death globally and the need for novel cancer therapies has never been more acute. The addition of I-Mab's novel CD47 programs complements our global clinical strategy in hematology and immuno-oncology," said Thomas J. Hudson, M.D., senior vice president of R&D and chief scientific officer, AbbVie. "We have been impressed with what I-Mab has been able to accomplish in research and clinical development and we look forward to working together to make a meaningful difference in the lives of millions of patients globally."

"At the forefront of drug innovation, our goal at I-Mab has always been to bring transformational therapies to patients globally. This strategic collaboration reinforces I-Mab's leading position in immuno-oncology and enables us to realize the full potential of our innovation," said Jingwu Zang, M.D., Ph.D., Founder, Honorary Chairman and Director of I-Mab. "We are extremely proud to partner with AbbVie. By leveraging the combined development strength of our companies, we aim to speed lemzoparlimab to market for patients in need around the world."
