GAITHERSBURG, MD, USA and SHANGHAI, China I July 22, 2022 I I-Mab (the “Company”) (Nasdaq: IMAB), a clinical-stage biopharmaceutical company committed to the discovery, development, and commercialization of novel biologics, today announced that the first patient in China has been treated with TJ-CD4B (also known as ABL111), a novel Claudin 18.2 x 4-1BB bispecific antibody, in a Phase 1 international multi-center clinical trial (IMCT) for patients with solid tumors, including gastric cancer, gastroesophageal junction carcinoma, esophageal adenocarcinoma, and pancreatic ductal carcinoma (NCT04900818).
TJ-CD4B is the first clinical-stage bispecific antibody of its drug class. It binds to Claudin 18.2-expressing cancer cells and co-stimulatory molecule 4-1BB on T cells to exert a tumor-killing effect. In March 2022, the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation for TJ-CD4B for the treatment of gastric cancer including cancer of gastroesophageal junction.
“Patients with gastric, esophageal and pancreatic cancers carry a poor prognosis with limited treatment options. TJ-CD4B has demonstrated its potential to become an effective treatment option in preclinical studies. In particular, TJ-CD4B is superior to other therapies targeting Claudin 18.2 and has a broader anti-tumor effect covering cancers expressing low levels of Claudin 18.2,” said Professor Lin Shen, Vice President of Clinical Oncology at the Beijing Cancer Hospital of Peking University, and leading principal investigator of the study. “The ongoing clinical testing of TJ-CD4B in cancer patients will help determine its treatment potential for a wide range of malignancies that currently lack effective therapies.”
“TJ-CD4B, powered by 4-1BB-activation platform, is a promising asset of the Company’s highly innovative bispecific antibody pipeline and represents the new generation of I-Mab’s continued innovation. This asset has the potential to treat highly challenging cancers, such as gastric cancer, one of the most prevalent cancer types in China and an illness that often suffers from poor prognosis,” said Dr. Andrew Zhu, President of I-Mab. “TJ-CD4B is being developed both in the U.S. and China. This is another important milestone in global clinical development of TJ-CD4B. We look forward to rapidly advancing the study to evaluate the key drug properties of TJ-CD4B for further development.”
About TJ-CD4B/ABL111
TJ-CD4B, also known as ABL111, is a Claudin 18.2 and 4-1BB bispecific antibody capable of binding to tumor cells expressing Claudin 18.2, i.e., gastric cancer and pancreatic cancer cells, and stimulating intra-tumoral T cells by the 4-1BB arm designed to be activated only upon tumor engagement while silent elsewhere. TJ-CD4B/ABL111 effectively maintains a strong tumor binding property and anti-tumor activity attributable to a synergistic effect of both Claudin 18.2 antibody and 4-1BB antibody while avoiding or minimizing liver toxicity and systemic immunotoxicity commonly seen with 4-1BB antibodies as a drug class. Being developed under collaboration between I-Mab and ABL Bio, a clinical-stage biotechnology company in South Korea, TJ-CD4B/ABL111 is currently being investigated in a phase 1 clinical study in the U.S. and China. In March 2022, the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation for TJ-CD4B/ABL111 for the treatment of gastric cancer, including cancer of gastroesophageal junction.
