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.
