    What is this summary about? This is a summary of the 1-year results of a clinical research study known as CheckMate 649 published in The Lancet in June 2021. The 2-year results on the participants' health and overall quality of life from the same study are in a second publication in Nature in March 2022. Until recently, chemotherapy was the only first treatment option for people with advanced or metastatic gastroesophageal adenocarcinoma who had not been treated before. Patients receiving chemotherapy lived on average for less than 1 year. Nivolumab is an immunotherapy that works by activating a person's immune system to fight back against cancer cells. The goal of CheckMate 649 was to find out if the combination of nivolumab and chemotherapy would help patients with advanced or metastatic gastroesophageal adenocarcinoma live longer and without their cancer getting worse.

    Background First-line chemotherapy for advanced or metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric or gastro-oesophageal junction adenocarcinoma has a median overall survival (OS) of less than 1 year. We aimed to evaluate first-line programmed cell death (PD)-1 inhibitor-based therapies in gastric, gastro-oesophageal junction, and oesophageal adenocarcinoma. We report the first results for nivolumab plus chemotherapy versus chemotherapy alone.

    Health-Related Quality of Life With Nivolumab Plus Chemotherapy Versus Chemotherapy in Patients With Advanced Gastric/Gastroesophageal Junction Cancer or Esophageal Adenocarcinoma From CheckMate 649
    (2023) Moehler, Markus; Xiao, Hong; Blum, Steven I.; Elimova, Elena; Cella, David; Shitara, Kohei; Ajani, Jaffer A.; Janjigian, Yelena Y.; Garrido, Marcelo; Shen, Lin; Yamaguchi, Kensei; Liu, Tianshu; Schenker, Michael; Kowalyszyn, Ruben; Bragagnoli, Arinilda Campos; Bruges, Ricardo; Montesarchio, Vincenzo; Pazo-Cid, Roberto; Hunter, Shannon; Davenport, Eric; Wang, Jinyi; Kondo, Kaoru; Li, Mingshun; Wyrwicz, Lucjan
    PURPOSE In CheckMate 649, first-line nivolumab plus chemotherapy prolonged overall survival versus chemotherapy in patients with advanced/metastatic non-human epidermal growth factor receptor 2 (HER2)-positive gastric/gastroesophageal junction cancer (GC/GEJC) or esophageal adenocarcinoma (EAC). We present exploratory patient-reported outcomes (PROs).METHODS In patients (N = 1,581) concurrently randomly assigned 1:1 to nivolumab plus chemotherapy or chemotherapy and in those with tumor PD-L1 expression at a combined positive score (CPS) of >= 5, health-related quality of life (HRQoL) was assessed using the EQ-5D and Functional Assessment of Cancer Therapy-Gastric (FACT-Ga), which included the FACT-General (FACT-G) and Gastric Cancer subscale (GaCS). The FACT-G GP5 item assessed treatment-related symptom burden. Longitudinal changes in HRQoL were assessed using mixed models for repeated measures in the PRO analysis population (randomly assigned patients with baseline and >= 1 postbaseline assessments). Time to symptom or definitive deterioration analyses were also conducted.RESULTS In the PRO analysis population (n = 1,360), PRO questionnaire completion rates were mostly >80% during treatment. Patient-reported symptom burden was not increased with nivolumab plus chemotherapy versus chemotherapy. Mean improved changes from baseline were greater with nivolumab plus chemotherapy versus chemotherapy for FACT-Ga total, GaCS, and EQ-5D visual analog scale in patients with a CPS of >= 5; results were similar for the overall PRO analysis population. In CPS >= 5 and all randomly assigned populations, nivolumab plus chemotherapy reduced the risk of symptom deterioration versus chemotherapy, on the basis of FACT-Ga total score and GaCS; time to definitive deterioration was longer, and the risk of definitive deterioration in HRQoL was reduced with nivolumab plus chemotherapy across EQ-5D and most FACT-Ga measures (hazard ratio [95% CI] <1).CONCLUSION Compared with chemotherapy alone, first-line nivolumab plus chemotherapy showed stable or better on-treatment HRQoL in patients with advanced/metastatic non-HER2-positive GC/GEJC/EAC and also showed decreased risk of definitive HRQoL deterioration.

    Nivolumab plus chemotherapy or ipilimumab in gastro-oesophageal cancer
    (2022) Shitara, Kohei; Ajani, Jaffer A.; Moehler, Markus; Garrido, Marcelo; Gallardo, Carlos; Shen, Lin; Yamaguchi, Kensei; Wyrwicz, Lucjan; Skoczylas, Tomasz; Bragagnoli, Arinilda Campos; Liu, Tianshu; Tehfe, Mustapha; Elimova, Elena; Bruges, Ricardo; Zander, Thomas; de Azevedo, Sergio; Kowalyszyn, Ruben; Pazo-Cid, Roberto; Schenker, Michael; Cleary, James M.; Yanez, Patricio; Feeney, Kynan; Karamouzis, Michalis, V; Poulart, Valerie; Lei, Ming; Xiao, Hong; Kondo, Kaoru; Li, Mingshun; Janjigian, Yelena Y.
    Standard first-line chemotherapy results in disease progression and death within one year in most patients with human epidermal growth factor receptor 2 (HER2)-negative gastro-oesophageal adenocarcinoma(1-4). Nivolumab plus chemotherapy demonstrated superior overall survival versus chemotherapy at 12-month follow-up in gastric, gastro-oesophageal junction or oesophageal adenocarcinoma in the randomized, global CheckMate 649 phase 3 trial(5) (programmed death ligand-1 (PD-L1) combined positive score >= 5 and all randomized patients). On the basis of these results, nivolumab plus chemotherapy is now approved as a first-line treatment for these patients in many countries(6). Nivolumab and the cytotoxic T-lymphocyte antigen-4 (CTLA-4) inhibitor ipilimumab have distinct but complementary mechanisms of action that contribute to the restoration of anti-tumour T-cell function and induction of de novo anti-tumour T-cell responses, respectively(7-)(11). Treatment combining 1 mg kg(-1) nivolumab with 3 mg kg(-1) ipilimumab demonstrated clinically meaningful anti-tumour activity with a manageable safety profile in heavily pre-treated patients with advanced gastro-oesophageal cancer(12). Here we report both long-term follow-up results comparing nivolumab plus chemotherapyversus chemotherapy alone and the first results comparing nivolumab plus ipilimumab versus chemotherapy alone from CheckMate 649. After the 24.0-month minimum follow-up, nivolumab plus chemotherapy continued to demonstrate improvement in overall survival versus chemotherapy alone in patients with PD-L1 combined positive >= 5 score (hazard ratio 0.70; 95% confidence interval 0.61, 0.81) and all randomized patients (hazard ratio 0.79; 95% confidence interval 0.71, 0.88). Overall survival in patients with PD-L1 combined positive score >= 5 for nivolumab plus ipilimumab versus chemotherapy alone did not meet the prespecified boundary for significance. No new safety signals were identified. Our results support the continued use of nivolumab plus chemotherapy as standard first-line treatment for advanced gastro-oesophageal adenocarcinoma.
