Enrique Grande, ESMO 2022: Post-hoc analysis investigating PD-L1 expression on immune cells, and improved OS with atezolizumab in patients with urothelial cancer

Published Online: September 13th 2022

PD-L1 assays use various methods to predict PD-L1/PD-1 blockade outcomes, recent data suggests clinically relevant PD-L1–expressing immune cells are dendritic cells. Dr Enrique Grande Pulido (MD Anderson Cancer Centre Madrid, Madrid, Spain) joins touchONCOLOGY to discuss a post-hoc analysis investigating PD-L1 expression on immune cells by SP142 co-localises with dendritic cells, and the associated improved overall survival with atezolizumab in patients with untreated metastatic urothelial cancer.

The abstract entitled ‘PD-L1 expression on immune cells by SP142 co-localises with dendritic cells and is associated with improved overall survival (OS) with atezolizumab in patients with untreated metastatic urothelial cancer (mUC)‘ Abstract 1735O, was presented at European Society for Medical Oncology (ESMO) 2022.

Questions:

  1. Could you give us a brief overview of PD-L1 assays to predict outcomes of PD-1/PD-L1 blockade, and their findings to date? (0:17)
  2. What did the IMvigor 130 trial teach us about the efficacy and safety of atezolizumab in patients with untreated metastatic urothelial cancer? (1:18)
  3. What were the aims and design of the post-hoc analysis you are presenting? (2:25)
  4. What were the findings of the analysis? (3:31)
  5. How can these findings be used to improve outcomes with PD-L1 inhibitors? (4:18)
