Excerpt:Tecentriq as monotherapy is indicated for the treatment of adult patients with locally advanced or metastatic urothelial carcinoma (UC):...after prior platinum containing chemotherapy, or...who are considered cisplatin ineligible, and whose tumours have a PD-L1 expression ≥ 5%.
Excerpt:TECENTRIQ is a programmed death-ligand 1 (PD-L1) blocking antibody indicated: Urothelial Carcinoma....for the treatment of adult patients with locally advanced or metastatic urothelial carcinoma who: are not eligible for cisplatin-containing chemotherapy and whose tumors express PD-L1 (PD-L1 stained tumor-infiltrating immune cells [IC] covering ≥ 5% of the tumor area), as determined by an FDA-approved test.

Excerpt:...the NCCN Panel recommends pembrolizumab, atezolizumab, nivolumab, durvalumab, avelumab, or erdafitinib as preferred second-line systemic therapy options after platinum-based therapy. Atezolizumab and pembrolizumab are also recommended as preferred first-line therapy options for patients who are not eligible for cisplatin-containing chemotherapy and whose tumors express PD-L1 or in patients who are not eligible for any platinum containing chemotherapy regardless of PD-L1 expression for locally advanced or metastatic disease.

Title:
Atezolizumab for untreated PD-L1-positive advanced urothelial cancer when cisplatin is unsuitable
Excerpt:Atezolizumab is recommended, within its marketing authorisation, as an option for untreated locally advanced or metastatic urothelial cancer in adults whose tumours express PD-L1 at a level of 5% or more and when cisplatin-containing chemotherapy is unsuitable.

658MO - Cisplatin (cis)-related immunomodulation and efficacy with atezolizumab (atezo) + cis- vs carboplatin (carbo)-based chemotherapy (chemo) in metastatic urothelial cancer (mUC)
Excerpt:PD-L1 IC 2/3 status is associated with longer OS in cis- but not carbo-treated pts with mUC...cis/gem induces immunogenic cell death and enhances antitumour immunity, particularly when combined with atezo.

Tumor, immune, and stromal characteristics associated with clinical outcomes with atezolizumab (atezo) + platinum-based chemotherapy (PBC) or atezo monotherapy (mono) versus PBC in metastatic urothelial cancer (mUC) from the phase III IMvigor130 study.
Excerpt:PD-L1 IC2/3 was associated with significantly longer OS for atezo mono vs placebo + PBC and a combination of PD-L1 IC2/3, and high TMB (> 10 muts/Mb) identified a pt subset (≈ 14% of BEP) with particularly favorable outcomes with atezo mono vs placebo + PBC; similar results for PD-L1 and TMB were not seen with atezo + PBC vs placebo + PBC.
