SHANGHAI and GAITHERSBURG, Md., Nov. 4, 2021 /PRNewswire/ -- I-Mab (the "Company") (Nasdaq: IMAB), a clinical stage biopharmaceutical company committed to the discovery, development and commercialization of novel biologics, today announced that an abstract summarizing the most recent clinical data from an ongoing clinical trial of its differentiated CD47 antibody lemzoparlimab (also known as TJC4), will be presented at the 63rd American Society of Hematology Annual Meeting (ASH 2021), taking place December 11 – 14, 2021.
The clinical data provide updates on the safety and efficacy of lemzoparlimab in combination with rituximab (Rituxan®) in relapsed or refractory non-Hodgkin's lymphoma (NHL). The trial (NCT03934814) is continuing to enroll more patients in the U.S., and has expanded to include clinical sites in China as an international multi-center clinical trial (IMCT). The study may potentially lead to the initiation of a registrational trial in 2022 in China .
The abstract is available online on the ASH 2021 website, and the presentation details are listed below.

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. 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. Scientists at I-Mab have discovered a novel CD47 antibody, lemzoparlimab, that is designed to target tumor cells while exerting a minimal untoward effect on red blood cells.
I-Mab continues to advance a combination study of lemzoparlimab with Keytruda® for solid tumors in the U.S. and with Rituxan® for lymphoma in the U.S. and China, in addition to an on-going clinical trial in patients with AML in China.
In September 2020, I-Mab and AbbVie entered into a global strategic collaboration to develop and commercialize lemzoparlimab. This includes the design and conduct of further clinical trials to evaluate lemzoparlimab in multiple cancers through global and China-specific trials. AbbVie has assumed sponsorship of the U.S. study as of April 2021.
