Phase 1 Trial of IMAB027 in Patients With Recurrent Advanced Ovarian Cancer (OVAR)
Study Details
Study Description
Brief Summary
Advanced ovarian cancer is a high medical need indication. Cure is not available to these patients and treatment has palliative intent. A proportion of advanced stage ovarian cancer expresses substantial levels of Claudin 6 (CLDN6), a carcino-embryonic transmembrane protein, which is absent from normal adult human tissue. IMAB027 is a monoclonal antibody that binds to CLDN6. Preclinically IMAB027 was shown to inhibit tumor growth and to kill cancer cells by antibody-dependent cellular cytotoxicity and complement-dependent cytotoxicity. This trial is a first-in-human dose escalation and dose finding Phase 1 trial of IMAB027 in patients with recurrent advanced ovarian cancer to assess the safety and tolerability, the pharmacokinetics, the antitumoral activity and the immunogenicity of IMAB027.
