ACC-001 (Active Immunotherapeutic Conjugate) with Wyeth
ACC-001 is a novel beta amyloid immunoconjugate that leverages the innovative conjugate technology that Wyeth has used in some of its vaccine products. ACC-001 has also been granted fast track designation by the FDA and is in Phase 2 clinical trials. The ACC-001 approach is intended to induce a highly specific antibody response to beta amyloid. The goal is to clear beta amyloid while minimizing side effects such as inflammation of the central nervous system.
