FDA approves atezolizumab for adjuvant treatment of muscle invasive bladder cancer in patients with molecular residual disease

On May 15, 2026, the Food and Drug Administration approved atezolizumab (Tecentriq, Genentech, Inc.) and atezolizumab and hyaluronidase-tqjs (Tecentriq Hybreza, Genentech, Inc.) as adjuvant treatments for adults with muscle invasive bladder cancer (MIBC) after cystectomy who have circulating tumor DNA molecular residual disease (ctDNA MRD) as determined by an FDA-authorized test.

Today, the FDA also approved Signatera CDx (Natera, Inc.) as a companion diagnostic device to select patients with MIBC after cystectomy who have ctDNA MRD for adjuvant treatment with Tecentriq or with Tecentriq Hybreza.
