NORTH CHICAGO, Illinois and SHANGHAI, China, September 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.

“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.”

“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.”

Collaboration Details

The collaboration established today provides AbbVie with an exclusive global license, excluding greater China, to develop and commercialize lemzoparlimab.  Both companies will collaborate to design and conduct further global clinical trials to evaluate lemzoparlimab in multiple cancers.  I-Mab retains all rights to develop and to commercialize lemzoparlimab in mainland China, Macau and Hong Kong.  The collaboration also allows for potential collaboration on future CD47-related therapeutic agents. Each party will have the opportunity subject to further licenses to explore each other’s related programs in their respective territories.

The companies will share manufacturing responsibilities with AbbVie being the primary manufacturer for global supply. The collaboration will accelerate I-Mab’s establishment of commercial production operations in China.

Financial Terms

Under the terms of the agreement, AbbVie will pay I-Mab USD 180 million in an upfront payment to exclusively license lemzoparlimab, along with USD 20 million in a milestone payment based on the phase 1 results, for a total of USD 200 million. In addition, I-Mab will be eligible to receive up to USD 1.74 billion in success-based milestone payments for lemzoparlimab, of which USD 840 million are based on clinical development and regulatory approval milestones, with the remainder based on commercial milestones. Upon commercialization of lemzoparlimab, AbbVie will also pay tiered royalties from low-to-mid teen percentages on global net sales outside of greater China.

About CD47 and Lemzoparlimab

CD47 is a cell surface protein over-expressed in a wide variety of cancers and can act to protect tumors by delivering a “don’t eat me” signal to otherwise tumor-engulfing macrophages.  CD47 antibody blocks this signal and enables macrophages to attack tumor cells, making it a potentially promising cancer drug. However, development of CD47 antibody as a cancer therapy is hampered by its hematologic side effects, such as severe anemia, caused by natural binding of CD47 antibody to red blood cells. In a scientific breakthrough, scientists at I-Mab have discovered a unique CD47 antibody, lemzoparlimab, that works efficiently to target tumor cells while exerting a minimal untoward effect on red blood cells to avoid severe anemia. 

Lemzoparlimab’s hematologic safety advantage and superb anti-tumor activities have been demonstrated previously in a series of robust pre-clinical studies. Today, the results of phase 1 clinical trial provide further clinical validation of this differentiation in patients with cancer. I-Mab continues to advance a combination study of lemzoparlimab with Keytruda® for solid tumor and with Rituxan® for lymphoma in US, in addition to an on-going clinical trial in patients with AML in China.
