1 CheckMate 12: Safety and Efficacy of First Line Nivolumab and Ipilimumab in Advanced Non-Small Cell Lung Cancer Abstract 31 Hellmann MD, Gettinger SN, Goldman J, Brahmer J, Borghaei H, Chow LQ, Ready NE, Gerber DE, Juergens R, Shepherd FA, Laurie SA, Young T, Geese WJ, Agrawal S, Li X, Antonia SJ

2 Rationale for Combined Immune Checkpoint Blockade With Nivolumab and Ipilimumab in Non-Small Cell Lung Cancer Nivolumab and ipilimumab enhance T-cell antitumor activity through distinct and complementary mechanisms 1 The combination of nivolumab and ipilimumab is approved in the US and EU for metastatic melanoma and has demonstrated encouraging clinical benefit across a number of tumor types 2- PFS With Nivo or Nivo + Ipi vs Ipi Alone in Previously Untreated Advanced Melanoma Proportion Alive and Progression-Free Nivo + Ipi Nivo Ipi Months Nivolumab monotherapy is approved in the US and EU for adults with locally advanced/metastatic NSCLC with progression either during or after platinum-doublet chemotherapy 1.

Presented at: The 16 th World Conference on Lung Cancer, September 6-9, 21; Denver, CO, United States: ORAL2.. Ipi, ipilimumab; Nivo, nivolumab; NSCLC, non-small cell lung cancer; PFS, progression-free survival

3 Phase I CheckMate 12 Study Design: Nivolumab Plus Ipilimumab in First-Line NSCLC Stage IIIB/IV NSCLC (any histology), no prior chemotherapy for advanced disease, ECOG PS or 1 Previous cohorts: Nivo 1 + Ipi 3 q 3 w x 4 Nivo 3 + Ipi 1 q 3 w x 4 Nivo 1 + Ipi 1 q 3 w x 4 Nivo 1 q 2 w + Ipi 1 q 6 w Nivo 3 q 2 w + Ipi 1 q 12 w Nivo 3 q 2 w + Ipi 1 q 6 w Nivo 3 q 2 w until disease progression a or unacceptable toxicity Until disease progression a or unacceptable toxicity Primary endpoint: safety and tolerability Secondary endpoints: ORR (RECIST v1.1) and PFS rate at 24 weeks Exploratory endpoints: OS, efficacy by PD-L1 expression The safety and tolerability of the nivo ipi combination was improved with less frequent ipilimumab dosing Schedules with nivolumab 3 mg/kg also showed increased clinical efficacy in a previous analysis Here, we report longer follow-up on nivolumab 3 mg/kg plus ipilimumab schedules b ECOG PS, Eastern Cooperative Oncology Group performance status; ORR, overall response rate; OS, overall survival, PD-L1, programmed cell-death ligand 1; RECIST, response evaluation criteria in solid tumors.
