The largest phase 3 trial in 1L metastatic ESCC1,7*
- Patients were also randomized to an experimental arm studying OPDIVO 3 mg/kg q2w in combination with ipilimumab 1 mg/kg q6w1§
- ||In patients who received OPDIVO in combination with chemotherapy and in whom either fluorouracil and/or cisplatin were discontinued, other components of the treatment regimen were allowed to be continued. Patients who discontinued combination therapy because of an adverse reaction attributed to ipilimumab were permitted to continue OPDIVO as a single agent1
- Tumor cell (TC), also called PD-L1 tumor proportion score (TPS), was evaluated using the PD-L1 IHC 28-8 pharmDx assay1
- The efficacy analysis in patients with TC PD-L1 ≥1% included 158 patients in the OPDIVO + chemotherapy arm, 158 patients in the OPDIVO + ipilimumab arm, and 157 patients in the chemotherapy arm1
- The trial excluded patients with brain metastasis that were symptomatic, had active autoimmune disease, used systemic corticosteroids or immunosuppressants, or patients at high risk of bleeding or fistula due to apparent invasion of tumor to organs adjacent to the esophageal tumor1
- Minimum follow-up at primary analysis was 12.9 months; minimum follow-up at extended follow-up analysis was 45.1 months1,3
*Checkmate 648 included a third arm: OPDIVO 3 mg/kg IV q2w + ipilimumab 1 mg/kg IV q6w; n=325. The trial was not designed to compare OPDIVO + chemotherapy to OPDIVO + ipilimumab. Please refer to the full U.S. Prescribing Information for further information.1,7
