PD-L1 IHC 22C3 pharmDx Testing for NSCLC

Image Description
PD-L1 is an essential first-line biomarker in NSCLC

In NSCLC, PD-L1 testing with PD-L1 IHC 22C3 pharmDx can help identify patients for first-line treatment with KEYTRUDA monotherapy1,2

  • Lung cancer is the leading cause of cancer-related mortality in Europe,3 and NSCLC accounts for ~85% of all lung cancer cases4
  • In 2017, KEYTRUDA became the first anti-PD-1 monotherapy EMA approved at first line for patients with metastatic NSCLC5
  • PD-L1 testing provides a direct assessment of PD-L1 expression, which is a biomarker for response to anti-PD-1 therapy in NSCLC1,2
  • PD-L1 testing with PD-L1 IHC 22C3 pharmDx was used to qualify patients with NSCLC for treatment with KEYTRUDA monotherapy in the KEYNOTE-024 and KEYNOTE-010* clinical trials1,2

PD-L1 IHC 22C3 pharmDx:
PD-L1 IHC 22C3 pharmDx is the ONE assay used to assess PD-L1 status across KEYTRUDA clinical trials

The only PD-L1 assay used in the KEYTRUDA KEYNOTE-024 and KEYNOTE-010 clinical trials in NSCLC1,2

PD-L1 IHC 22C3 pharmDx is CE-IVD–marked as the clinical trial-proven companion diagnostic for KEYTRUDA monotherapy, and was used to assess PD-L1 expression and select patients for treatment in in KEYNOTE-024 and KEYNOTE-0101

* KEYNOTE-010 evaluated the safety and efficacy of KEYTRUDA in patients with advanced NSCLC previously treated with platinum-containing chemotherapy. Patients were screened for enrollment using a clinical-trial assay, † Merck & Co., data on file, ‡ Patients screened for enrollment in KEYNOTE-024 NSCLC, § Patients screened for enrollment in KEYNOTE-010 NSCLC using the clinical-trial assay, ¶ Patients tested with PD-L1 IHC 22C3 pharmDx, ** 2 mg/kg every 3 weeks. For efficacy data on the 10 mg/kg treatment arm, review the Instructions for Use

Note: PD-L1 testing with PD-L1 IHC 22C3 pharmDx was used to qualify patients with NSCLC for first-line treatment with KEYTRUDA monotherapy in the KEYNOTE-042 clinical trial. For more information on the KEYNOTE clinical trials, review the Instructions for Use.
