May 18, 2026—The FDA has approved Natera’s Signatera CDx as a companion diagnostic for use with adjuvant atezolizumab (Tecentriq) immunotherapy in muscle-invasive bladder cancer to identify patients who are ctDNA molecular residual disease–positive and may benefit from treatment. Results from the global phase three IMvigor011 trial, sponsored by Genentech, demonstrated that Signatera MRD-positive patients treated with immunotherapy achieved significant improvements in disease-free and overall survival, while Signatera MRD-negative patients achieved 97 percent two-year overall survival with no adjuvant therapy (Powles T, et al. N Engl J Med. 2025;393[24]:2395–2408).
