I-Mab Announces First Patient Dosed in Phase 1/2a Clinical Trial of Anti-CD47 Antibody,
SHANGHAI, China, and ROCKVILLE, MD., April 2, 2020 I-Mab
(the Company ) (Nasdaq: IMAB), a clinical stage biopharmaceutical company committed to the discovery, development and commercialization of novel or highly differentiated biologics to treat diseases with significant unmet medical needs,
particularly cancers and autoimmune disorders, today announced that the first patient was dosed with TJC4 in a Phase 1/2a clinical trial evaluating its use in treating patients with relapsed or refractory acute myeloid leukemia (r/r AML) or
myelodysplastic syndrome (MDS) in China. TJC4, also known as TJ011133, is an internally developed differentiated anti-CD47 monoclonal antibody that is designed to minimize inherent binding to normal red blood cells while preserving its strong
anti-tumor activity.
The clinical trial in China is a multi-center, open-label, single-arm study to evaluate the
safety, tolerability, pharmacokinetics/pharmacodynamics and preliminary efficacy of TJC4 as a monotherapy in patients with r/r AML and MDS (CXSL1900039; NCT04202003;). I-Mab is also conducting a Phase 1 trial
(NCT Number: NCT03934814) in the U.S. in patients with advanced solid tumors and lymphoma, with complete data from the dose escalation portion expected in the third quarter of 2020.
We have been at full speed conducting clinical development of TJC4 in both U.S. and China, said Dr. Joan Shen, CEO of I-Mab. Dosing the first patient in China represents another important milestone, both for our TJC4 program and for patients, as TJC4 stands out as a globally competitive, highly differentiated anti-CD47 asset
for cancer treatment. Together with the Phase 1 dose escalation study of TJC4 in the U.S., we continue to leverage our clinical development capabilities and expertise to facilitate clinical validation of TJC4 in China and the U.S.
CD47 is a glycoprotein
over-expressed in a wide variety of cancers and delivers a don t eat me signal to tumor-engulfing macrophages through its ligand SIRP , and is one of the most promising immuno-oncology targets after PD-1 and PDL1.
TJC4 is a differentiated anti-CD47 monoclonal antibody and designed to minimize inherent binding to
normal red blood cells by this class of monoclonal antibodies yet preserve its strong anti-tumor activities. Blockade of CD47 by TJC4 enables macrophages to engulf cancer cells. TJC4 recognizes a unique epitope on CD47 and exhibits minimal binding
to red blood cells. The hematologic safety advantage of TJC4 has been demonstrated in a series of robust pre-clinical and toxicological studies including those in cynomolgus monkeys, while it maintains superb
anti-tumor activities.
