Patients and methods: Preliminary results from the phase II 'FAST' trial in June 2016 suggest it is helpful for advanced gastric cancer (and a phase III trial will be planned). 2011 May;15 Suppl 1:33-42. doi: 10.3310/hta15suppl1/04. IMAB362 binds to the tight junction protein Claudin-18.2 which is expressed in up to 80% of gastroesophageal adenocarcinomas, 60% of pancreatic tumors as well as in other various solid tumors. Safety/tolerability, including determination of maximum tolerated dose and recommended phase II dose, were the primary objectives; secondary objectives included assessment of the IMAB362 pharmacokinetic profile, immunogenicity, and antitumour activity (assessed by … The aim of this phase II study is to establish efficacy and safety of multiple doses of IMAB362 as monotherapy in patients suffering from metastatic, refractory or recurrent adenocarcinoma of the stomach or the lower esophagus. e15079 Background: IMAB362 is the first-in-class monoclonal antibody against the tight junction molecule claudin 18.2 (CLDN18.2) executing its antitumor activity via 4 highly potent modes of action (antibody-dependent cellular cytotoxicity [ADCC], complement-dependent cytotoxicity, proliferation inhibition, apoptosis). Online ahead of print. National Library of Medicine Background: Physiologically, the tight junction protein CLDN18.2 is present only in the gastric mucosa. CLDN18.2 is a tumour-specific marker in gastric or gastro-oesophageal junction cancers. Trastuzumab for the treatment of HER2-positive metastatic adenocarcinoma of the stomach or gastro-oesophageal junction. Upon malignant transformation, CLDN18.2 epitopes are exposed on the cell surface and accessible to targeted therapy. Zolbetuximab 800/600 mg/m2 is being evaluated in phase III studies based on clinical benefit observed in the overall population and in patients with moderate-to-strong CLDN18.2 expression in ≥70% of tumour cells.

A Phase 2 Study of Zolbetuximab (IMAB362) as Monotherapy or in Combination with mFOLFOX6 in Subjects with Metastatic or Locally Advanced Unresectable Gastric or Gastroesophageal Junction (GEJ) Adenocarcinoma whose Tumors have High or Intermediate Claudin (CLDN) 18.2 Expression A monoclonal antibody, zolbetuximab (formerly known as IMAB362), has been generated against CLDN18.2. For people ages 16 and 17, a parent or guardian must call their doctor’s office. In the overall population, both PFS [hazard ratio (HR) = 0.44; 95% confidence interval (CI), 0.29-0.67; P < 0.0005] and OS (HR = 0.55; 95% CI, 0.39-0.77; P < 0.0005) were significantly improved with zolbetuximab + EOX (arm 2) compared with EOX alone (arm 1). In Phase 3, the goal is to test the medicine compared to different treatments. The drug is in phase II clinical trials as of January 2013. Zolbetuximab, a chimeric monoclonal antibody, mediates specific killing of CLDN18.2-positive cells through immune effector mechanisms.
