PD-L1 IHC 22C3 pharmDx for Urothelial Carcinoma

Image Description
PD-L1 IHC 22C3 pharmDx can help identify urothelial carcinoma patients for treatment with KEYTRUDA

PD-L1 is a proven biomarker for patient response to KEYTRUDA in urothelial carcinoma1,2

  • More than a third of all global incidences of urothelial carcinoma are reported in Europe, and few advancements in treatment have been made
  • Anti-PD-1 therapies are a promising new treatment class for many cancer types—the KEYNOTE-052 and KEYNOTE-045 clinical trials studied the efficacy of KEYTRUDA, an anti-PD-1 monotherapy, at first-line and second-line respectively, in specific urothelial carcinoma patient populations
  • IHC testing for PD-L1 expression levels enables identification of patients most likely to benefit from anti-PD-1 monotherapy

PD-L1 IHC 22C3 pharmDx:
Trust the ONE PD-L1 test CE-IVD–marked to determine PD-L1 expression in patients with urothelial carcinoma for KEYTRUDA treatment

Proven in KEYNOTE-052 and KEYNOTE-045 for PD-L1 results in urothelial carcinoma1,2

  • PD-L1 IHC 22C3 pharmDx was the only IHC assay used to assess PD-L1 expression in the KEYNOTE-052 and KEYNOTE-045 trials
    • KEYNOTE-052 evaluated objective response rate (ORR) in locally advanced or metastatic urothelial carcinoma patients ineligible for cisplatin-containing chemotherapy
    • KEYNOTE-045 evaluated overall survival in locally advanced or metastatic urothelial carcinoma patients previously treated with platinum-based chemotherapy

PD-L1 testing with PD-L1 IHC 22C3 pharmDx should be an integral part of patient care from day ONE

More than half of all patients with advanced urothelial carcinoma are ineligible for first-line cisplatin-based chemotherapy treatment

  • Renal dysfunction, poor performance status, or other comorbidities can cause patients to be ineligible for treatment
  • There is no standard of care for patients who can not receive cisplatin-based chemotherapy
  • Additionally, for patients who receive cisplatin-based chemotherapy and relapse, there is no standard of care and the median overall survival is reduced to 6–7 months
