CHECKMATE 227: IN A CROSS-HISTOLOGY TRIAL FOR PATIENTS WITH mNSCLC
Durable survival with OPDIVO® + YERVOY®:
24% of patients alive at 5 years2*
A chance for
OS FOR PD-L1 ≥1%
(EXTENDED FOLLOW-UP ANALYSIS)1-3
Between 2007 and 2013, prior to I-O approval,
the 5-year relative survival
rate for mNSCLC patients was 5%4†
Median follow-up of 66.7 months.2
The only I-O combination with mDOR of 24.5 months among responders2
vs chemo. In Checkmate 227, patients in the comparator arm received up to 4 cycles of platinum-doublet chemo q3w; NSQ: pemetrexed + carboplatin or cisplatin, with optional pemetrexed maintenance following chemo; SQ: gemcitabine + carboplatin or cisplatin.1,6

In Checkmate 227 Part 1a, PFS, ORR, and DOR were pre-specified descriptive analyses. The primary efficacy outcome measure was OS.1,6
Study design: Checkmate 227 was a randomized, open-label, phase 3 trial in patients with metastatic or recurrent NSCLC. Key eligibility criteria included patients 18 years or older, stage IV or recurrent NSCLC, ECOG PS 0/1, and no prior systemic anticancer therapy. Patients with known EGFR mutations or ALK translocations sensitive to available targeted inhibitor therapy, untreated brain metastases, carcinomatous meningitis, active autoimmune disease, or medical conditions requiring systemic immunosuppression were excluded from the study. Treatment continued until disease progression, unacceptable toxicity, or for up to 24 months. Tumor specimens were evaluated prospectively using the PD-L1 IHC 28-8 pharmDx assay at a central laboratory. In Part 1a (n=793), patients with PD-L1 ≥1% were randomized to either OPDIVO 3 mg/kg q2w* + YERVOY 1 mg/kg q6w (n=396) or platinum-doublet chemotherapy† (n=397). The primary endpoint in Part 1a was OS in patients with PD-L1 ≥1%. Pre-specified descriptive efficacy outcome measures included PFS, ORR, and DOR.1,2
The recommmended PI dose of OPDIVO is 360 mg q3w with YERVOY 1 mg/kg q6w.1
In Checkmate 227, patients in the comparator arm received up to 4 cycles of platinum-doublet chemo q3w; NSQ: pemetrexed + carboplatin or cisplatin, with optional pemetrexed maintenance following chemo; SQ: gemcitabine + carboplatin or cisplatin.1,6
