Title: Preliminary Safety, PK/PD, and Antitumor Activity of XmAb18087, an SSTR2 x CD3 Bispecific Antibody, in Patients with Advanced Neuroendocrine Tumors
Presenter: Bassel El-Rayes, M.D., Professor and Vice Chair for Clinical Research of the Department of Hematology and Medical Oncology at Emory University School of Medicine, as well as Director of the Gastrointestinal Oncology Program at Winship Cancer Institute
Session: Clinical Abstracts
Date & Time: Saturday, October 3, 2020, 2:00 p.m. ET
Tidutamab (XmAb®18087) is a tumor-targeted bispecific antibody that contains both an SSTR2 binding domain and a T-cell binding domain (CD3). An XmAb® bispecific Fc domain serves as the scaffold for the two antigen binding domains and confers long circulating half-life, stability and ease of manufacture on tidutamab. SSTR2 (somatostatin receptor 2) is an antigen highly expressed on some solid tumors, and engagement of CD3 by tidutamab activates T cells for highly potent and targeted killing of SSTR2-expressing tumor cells. Tidutamab is being evaluated in an ongoing Phase 1 study, which is enrolling patients with neuroendocrine tumors (NETs) and gastrointestinal stromal tumors (GISTs).
