CEA (carcinoembryonic antigen)

Description

ETBX-011 is a recombinant adenovirus type 5 (Ad5) based cancer vaccine that targets carcinoembryonic antigen (CEA) expressing tumors. This immunotherapy agent is designed as a therapeutic vaccine for patients with CEA-positive colorectal cancer and other solid tumors. The vaccine uses a modified adenoviral vector (E1-, E2b- deleted) to deliver CEA(6D), a modified version of the CEA antigen, to stimulate anti-tumor immune responses.

Mechanism of Action

ETBX-011 works by using a replication-defective adenoviral vector to deliver the CEA(6D) antigen to antigen-presenting cells, particularly dendritic cells. This presentation stimulates both CD4+ and CD8+ T-cell responses against CEA-expressing tumor cells, generating targeted cytotoxic T-lymphocyte activity. The vaccine aims to break immune tolerance to the CEA self-antigen and create lasting immunological memory against CEA-positive cancer cells.
