Abstract Background Nivolumab showed improvement in overall survival (OS) in ATTRACTION-2, the first phase 3 study in patients with gastric/gastroesophageal junction (G/GEJ) cancer treated with ≥ 2 chemotherapy regimens. The 2-year follow-up results of ATTRACTION-2 are presented herein. Methods ATTRACTION-2 was a randomized, double-blind, placebo-controlled, phase 3 trial (49 sites; Japan, South Korea, and Taiwan). The median (min–max) follow-up period was 27.3 (24.1–36.3) months. The primary endpoint was OS. A subanalysis of OS was performed based on best overall response and tumor-programmed death ligand-1 (PD-L1) expression status. Results Overall, 493 of 601 screened patients were randomized (2:1) to receive nivolumab (330) or placebo (163). OS (median [95% confidence interval; CI]) was significantly longer in the nivolumab group (5.26 [4.60–6.37] vs 4.14 [3.42–4.86] months in placebo group) at the 2-year follow-up (hazard ratio [95% CI], 0.62 [0.51–0.76]; P < 0.0001). A higher OS rate was observed in the nivolumab vs placebo group at 1 (27.3% vs 11.6%) and 2 years (10.6% vs 3.2%). The OS benefit was observed regardless of tumor PD-L1 expression. Among patients with a complete or partial response (CR or PR) in the nivolumab group, the median OS (95% CI) was 26.6 (21.65—not applicable) months; the OS rates at 1 and 2 years were 87.1% and 61.3%, respectively. No new safety signals were identified. Conclusions Nivolumab treatment resulted in clinically meaningful long-term improvements in OS in patients with previously treated G/GEJ cancer. The long-term survival benefit of nivolumab was most evident in patients with a CR or PR.

Checkmate 649: A randomized, multicenter, open-label, phase 3 study of nivolumab (Nivo) plus ipilimumab (Ipi) versus oxaliplatin plus fluoropyrimidine in patients (Pts) with previously untreated advanced or metastatic gastric (G) or gastroesophageal junction (GEJ) cancer.

TPS213 Background: The combination ofoxaliplatin and fluoropyrimidine is a standard-of-care (SOC) first-line treatment of pts with metastatic G/GEJ cancer, resulting in a median overall survival (OS) of 8–11 months and objective response rate (ORR) of 30%–50%. This is accompanied by up to 77% grade 3/4 toxicities. Therefore, new treatment options are needed to improve survival and decrease toxicity in G/GEJ cancer. Nivo, a fully human IgG4 monoclonal antibody (mAb) that targets programmed death 1 (PD-1) and ipi, a fully human IgG1 mAb that targets cytotoxic T-lymphocyte–associated protein 4, have demonstrated manageable safety profiles and efficacy in multiple tumor types and may have a synergistic effect. In a phase 1/2 study in chemotherapy-refractory pts with G/GEJ/esophageal cancer with or without PD-1 ligand 1 (PD-L1) expression, second-line nivo 1 mg/kg + ipi 3 mg/kg demonstrated a manageable safety profile and resulted in 26% ORR (44% ORR in pts with PD-L1+ tumors), median OS of 6.9 months, and a 34% OS rate at 12 months (Janjigian Y, et al. J Clin Oncol. 2016;34[suppl][abstract 4010]). This open-label, phase 3 trial will evaluate nivo + ipi as first-line therapy for pts with G/GEJ cancer (CheckMate 649; NCT02872116). Methods: In this study, 870 pts aged ≥ 18 years with untreated advanced or metastatic G/GEJ cancer with or without PD-L1 expression will be randomized to receive nivo + ipi (4 doses; followed by nivo monotherapy) or investigator’s choice of capecitabine/oxaliplatin (XELOX) or fluorouracil/leucovorin/oxaliplatin (FOLFOX). Tumor tissue for determination of PD-L1 status must be provided from ≤ 6 months before study treatment. Pts receiving chemotherapy or radiotherapy for G/GEJ cancer within the last 6 months or pts with suspected autoimmune disease, uncontrolled medical disorder, or active infection are excluded. Primary endpoint is OS in pts with PD-L1+ tumors. Secondary endpoints include OS in all pts and progression-free survival and time to symptom deterioration in all pts and pts with PD-L1+ tumors. Clinical trial information: NCT02872116.

TPS4132 Background: Pts with adv G/GEJ cancer have an OS of ≈ 1 y, indicating an unmet medical need for new first-line treatments (Tx). Expression of the PD-1 ligands PD-L1/PD-L2 is observed in up to 40% of pts with G/GEJ cancer and is associated with poor prognosis. In a phase 3 study of the PD-1 inhibitor nivo vs placebo in pts with adv CTX-refractory (CTX-R; ≥ 2 lines) G/GEJ cancer, nivo reduced the risk of death by 37% (HR, 0.63; P < 0.0001) and increased the OS rate at 12 mo (27% vs 11%; Kang YK, et al. J Clin Oncol. 2017;35 (suppl 4S) [abstract 2]). In a phase 1/2 study in pts with CTX-R G/GEJ/esophageal cancer (79% ≥ 2 prior Tx lines), nivo 1 mg/kg + ipi 3 mg/kg had a manageable safety profile and resulted in 26% ORR (44% ORR in pts with PD-L1+ tumors), a median OS of 6.9 mo, and a 34% OS rate at 12 mo (Janjigian Y, et al. ASCO, 2016 [abstract 4010]). In the phase 1 CheckMate 012 trial, nivo + CTX had clinical activity and manageable safety in pts with NSCLC (Rizvi NA, et al. J Clin Oncol. 2016;34:2969-2979). These positive results support investigation of nivo, nivo + ipi, and nivo + CTX in earlier lines of Tx for G/GEJ cancer. The open-label, phase 3 CheckMate 649 trial will evaluate nivo + ipi and nivo + CTX vs CTX alone as first-line Tx for pts with adv G/GEJ cancer (NCT02872116). Methods: 1266 pts aged ≥ 18 y with untreated, inoperable adv/metastatic G/GEJ cancer (histologically confirmed adenocarcinoma) regardless of PD-L1 status will be randomized to receive either nivo + ipi, nivo + CTX (capecitabine/oxaliplatin [XELOX] or fluorouracil/leucovorin/oxaliplatin [FOLFOX]), or investigator choice of XELOX or FOLFOX. Tumor tissue for determination of PD-L1 status (Dako assay) must be provided from ≤ 6 mo before study Tx. No prior systemic Tx, including HER2 inhibitors, are allowed. Pts with known HER2+ status, suspected autoimmune disease, grade > 1 peripheral neuropathy, or active infection are excluded. Primary endpoint is OS in pts with PD-L1+ (≥ 1%) tumors. Other endpoints include OS in all pts; PFS and time to symptom deterioration in all pts and in pts with PD-L1+ tumors; and safety. Clinical trial information: NCT02872116.
