A multicentre, phase IIa study of zolbetuximab as a single agent in patients with recurrent or refractory advanced adenocarcinoma of the stomach or l…

Abstract Background Claudin 18.2 (CLDN18.2) is physiologically confined to gastric mucosa tight junctions; however, upon malignant transformation, perturbations in cell polarity lead to CLDN18.2 epitopes being exposed on the cancer cell surface. The first-in-class monoclonal antibody, zolbetuximab (formerly known as IMAB362), binds to CLDN18.2 and can induce immune-mediated lysis of CLDN18.2-positive cells. Patients and methods Patients with advanced gastric, gastro-oesophageal junction (GEJ) or oesophageal adenocarcinomas with moderate-to-strong CLDN18.2 expression in ≥50% of tumour cells received zolbetuximab intravenously every 2 weeks for five planned infusions. At least three patients …
Preclinical evaluation of the anti-CLDN18.2 antibody, IMAB362, in pancreatic carcinoma

Characterization of zolbetuximab in pancreatic cancer models
2018
ABSTRACT In healthy tissue, the tight junction protein Claudin 18.2 (CLDN18.2) is present only in the gastric mucosa. Upon malignant transformation of gastric epithelial tissue, perturbations in cell polarity lead to cell surface exposure of CLDN18.2 epitopes. Moreover, CLDN18.2 is aberrantly expressed in malignancies of several other organs, such as pancreatic cancer (PC). A monoclonal antibody, zolbetuximab (formerly known as IMAB362), has been generated against CLDN18.2. In a phase 2 clinical trial (FAST: NCT01630083), zolbetuximab in conjunction with chemotherapy prolonged overall and progression-free survival over chemotherapy alone and improved quality of life. In this study, the mech…
Abstract 2903: IMAB362, a novel first-in-class monoclonal antibody for treatment of pancreatic cancer
2014
Abstract Pancreatic ductal adenocarcinoma (PDAC), the most frequent subtype (>80%) of pancreatic cancer (PC) is characterized by a generally lethal progress within a short period of time after primary diagnosis. Despite high efforts, the treatment options are very limited and mainly of palliative nature. Therefore, we investigated whether IMAB362 might represent a potential treatment option in this patient population. IMAB362 is a highly potent and tumor-cell selective therapeutic antibody which is currently in clinical development in gastro-esophageal cancer (in phase II and IIb trials). IMAB362 is directed against the tight junction molecule CLDN18.2, a proliferation-promoting tran…
Claudin 18.2 is a target for IMAB362 antibody in pancreatic neoplasms
2013
The majority of pancreatic neoplasms are characterized by a generally lethal progress within a short period of time after primary diagnosis and the mortality of patients is expected to increase further. Due to lack of efficient screening programs and moderate response to treatments, novel compounds for treatment are needed. We investigated the CLDN18.2 expression in affected patients as in vitro feasibility study for a potential treatment with the novel antibody IMAB362. Therefore, we analyzed the expression of CLDN18.2 in normal pancreatic tissues (N = 24), primary lesions (N = 202), metastases (N = 84) and intra-individually matched samples (N = 48) of patients with pancreatic ductal aden…
Comparison of Claudin 18.2 expression in primary tumors and lymph node metastases in Japanese patients with gastric adenocarcinoma.
2019
CLDN18.2 expression is highly prevalent in Japanese patients with gastric cancer, making it a targetable alteration, and supporting development of zolbetuximab as a therapeutic agent for this patient population.
