Claudiximab is a monoclonal antibody specific for gastric and gastroesophageal adenocarcinomas. Preclinically, claudiximab was shown to inhibit tumor growth and to kill cancer cells by indirect (complement-dependent cytoxicity, antibody-dependent cellular cytotoxicity) and direct mechanisms (antiproliferative and proapoptotic effects). The aim of this phase I study is to establish safety, toxicity and maximal tolerable dose of a single infusion of claudiximab in patients suffering from relapsing, advanced gastroesophageal and gastric adenocarcinoma

Condition Intervention Phase
Solid Tumors
Drug: Claudiximab
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Official Title: Clinical First-in-human Single-dose Escalation Study Evaluating the Safety and Tolerability of Claudiximab (iMAB-362) in Hospitalized Patients With Advanced Gastroesophageal Cancer. A Multi-center, Phase I, Open-label, i.v. Infusion Study

Further study details as provided by Ganymed Pharmaceuticals AG:

Primary Outcome Measures:
  • Determination of maximum tolerated dose of claudiximab (Phase I: toxicities as assessed by NCI CTCAE version 3.0) [ Time Frame: Four weeks ]

Secondary Outcome Measures:
  • Determination of the safety profile [ Time Frame: Four weeks ]
  • Pharmacokinetic evaluation [ Time Frame: Four weeks ]
  • Overall tumor response as assessed by RECIST [ Time Frame: Four weeks ]
  • Evaluation of immunogenicity [ Time Frame: Four weeks ]
  • Determination of antitumoral efficacy [ Time Frame: Four weeks ]

Enrollment: 15
Study Start Date: May 2009
Study Completion Date: May 2010
Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Claudiximab Drug: Claudiximab

Patients receive Claudiximab as intravenous infusion over 2 hours on day 1. Cohorts of 3-6 patients receive escalating doses of Claudiximab until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no dose-limiting toxicity (DLT) is diagnosed in 3 patients or no more than 1 out of 6 patients exhibits a DLT.

After completion of study treatment, patients are followed for 4 weeks.
