Opdivo showed better in overall survival versus chemotherapy in advanced esophageal Cancer
September 30, 2019Opdivo demonstrated a 23% reduction in the risk of death and 2.5-month improvement in median overall survival compared to chemotherapy, according to results from Phase 3 ATTRACTION-3 trial to be featured in a Presidential Symposium during the European Society for Medical Oncology 2019 Annual Congress.
PRINCETON, N.J.–(BUSINESS WIRE)–$BMY #BMS—Bristol-Myers Squibb Company (NYSE: BMY) and Ono Pharmaceutical Co., Ltd. today announced results from the Phase 3 ATTRACTION-3 trial evaluating Opdivo (nivolumab) versus chemotherapy (docetaxel or paclitaxel) for the treatment of patients with unresectable advanced or recurrent esophageal squamous cell carcinoma (ESCC) refractory or intolerant to combination therapy with fluoropyrimidine and platinum-based drugs. For the primary endpoint of overall survival (OS), Opdivo demonstrated a statistically significant improvement over chemotherapy, with a 23% reduction in risk of death [Hazard Ratio (HR) 0.77; 95% Confidence Interval (CI): 0.62 to 0.96; p=0.019] and a 2.5-month improvement in median OS [10.9 months (95% CI: 9.2 to 13.3)] compared to patients treated with chemotherapy [8.4 months (95% CI: 7.2 to 9.9)]. The safety profile of Opdivo in this trial was consistent with previously reported studies in ESCC and other solid tumors.
These data (Presentation #LBA11) will be featured in the Presidential Symposium on Monday, September 30 from 4:30-6:15 PM CEST at the European Society for Medical Oncology (ESMO) 2019 Annual Congress in Barcelona, Spain and simultaneously published in The Lancet Oncology.
Patients treated in the Opdivo arm showed 12- and 18-month OS rates of 47% (95% CI: 40 to 54) and 31% (95% CI: 24 to 37), respectively, versus 34% (95% CI: 28 to 41) and 21% (95% CI: 15 to 27) among patients in the chemotherapy arm. Survival benefit with Opdivo was observed regardless of tumor PD-L1 expression levels. An exploratory analysis of patient-reported outcomes showed significant overall improvement in quality of life with Opdivo versus chemotherapy.
“The significant survival benefit coupled with the favorable safety profile and patient-reported outcomes observed in this trial suggest Opdivo has the potential to represent an important new second-line treatment option for patients with advanced esophageal squamous cell carcinoma, offering the possibility to extend their survival and improve their quality of life during treatment,” said Dr. Byoung Chul Cho, Professor, Yonsei Cancer Center, Yonsei University College of Medicine.
The objective response rates (ORR) between the two arms were comparable at 19% (95% CI: 14 to 26) among patients receiving Opdivo versus 22% (95% CI: 15 to 29) among those receiving chemotherapy. However, the study showed Opdivo substantially increased the median duration of response (DoR) for patients [6.9 months (95% CI: 5.4 to 11.1) versus 3.9 months (95% CI: 2.8 to 4.2)]. Seven patients in the Opdivo arm had ongoing responses at data cutoff compared to two patients in the chemotherapy arm. An overall HR of 1.08 (95% CI: 0.87 to 1.34) suggested no meaningful difference in progression-free survival (PFS) between the Opdivo and chemotherapy arms.
“These are very promising results for patients with advanced esophageal squamous cell carcinoma for whom prognosis is typically poor and are particularly important given Opdivo improved survival regardless of PD-L1 status,” said Ian M. Waxman, M.D., development lead, Gastrointestinal Cancers, Bristol-Myers Squibb. “We are encouraged to see important progress being made in this tumor type and look forward to broadening our research in gastrointestinal tumors.”
Fewer treatment-related adverse events (TRAEs) were reported with Opdivo versus chemotherapy, with a rate of 66% of any grade TRAEs for patients receiving Opdivo compared to 95% for patients receiving chemotherapy. Patients in the Opdivo arm also experienced a lower incidence of Grade 3 or 4 TRAEs compared to those in the chemotherapy arm (18% versus 63%), and the percentage of patients experiencing TRAEs leading to discontinuation was the same in both arms (9%).
About ATTRACTION-3
ATTRACTION-3 (ONO-4538-24/CA209-473; NCT02569242) is a Phase 3, multi-center, randomized, open-label global study, evaluating Opdivo versus chemotherapy (docetaxel or paclitaxel) for patients with esophageal cancer refractory or intolerant to first-line combination therapy with fluoropyrimidine and platinum-based drugs. Patient enrollment occurred predominantly in Asia with 96% of patients in both treatment arms from Asia. Patients were treated until disease progression or unacceptable toxicity. The primary endpoint of the trial is OS. Secondary endpoints include investigator-assessed ORR, PFS, disease control rate, DoR and safety. This trial was sponsored by Ono Pharmaceutical Co. Ltd. of Japan, Bristol-Myers Squibb’s development partner for Opdivo.
About Esophageal Cancer
Esophageal cancer is the seventh most common cancer and the sixth most common cause of death from cancer worldwide. The five-year relative survival rate is 8% or less for patients diagnosed with metastatic disease. The two most common types of esophageal cancer are squamous cell carcinoma and adenocarcinoma, which account for approximately 90% and 10% of all esophageal cancers, respectively. Each year, an estimated 572,000 new cases are diagnosed and approximately half a million deaths are caused by esophageal cancer. The majority of cases are diagnosed in the advanced setting and impact a patient’s daily life, including their ability to eat and drink. The prevalence of esophageal cancer is highest in Asia, with over 444,000 cases diagnosed yearly, accounting for about 80% of all esophageal cancer cases worldwide.

About Opdivo
Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.
Opdivo’s leading global development program is based on Bristol-Myers Squibb’s scientific expertise in the field of Immuno-Oncology, and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has treated more than 35,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.
In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

IMPORTANT SAFETY INFORMATION
WARNING: IMMUNE-MEDIATED ADVERSE REACTIONS
YERVOY can result in severe and fatal immune-mediated adverse reactions. These immune-mediated reactions may involve any organ system; however, the most common severe immune-mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. The majority of these immune-mediated reactions initially manifested during treatment; however, a minority occurred weeks to months after discontinuation of YERVOY.
Assess patients for signs and symptoms of enterocolitis, dermatitis, neuropathy, and endocrinopathy, and evaluate clinical chemistries including liver function tests (LFTs), adrenocorticotropic hormone (ACTH) level, and thyroid function tests, at baseline and before each dose.
Permanently discontinue YERVOY and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions.
Immune-Mediated Pneumonitis
OPDIVO can cause immune-mediated pneumonitis. Fatal cases have been reported. Monitor patients for signs with radiographic imaging and for symptoms of pneumonitis. Administer corticosteroids for Grade 2 or more severe pneumonitis. Permanently discontinue for Grade 3 or 4 and withhold until resolution for Grade 2. In patients receiving OPDIVO monotherapy, fatal cases of immune-mediated pneumonitis have occurred. Immune-mediated pneumonitis occurred in 3.1% (61/1994) of patients. In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated pneumonitis occurred in 6% (25/407) of patients. In RCC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated pneumonitis occurred in 4.4% (24/547) of patients. In MSI-H/dMMR mCRC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated pneumonitis occurred in 1.7% (2/119) of patients.
In Checkmate 205 and 039, pneumonitis, including interstitial lung disease, occurred in 6.0% (16/266) of patients receiving OPDIVO. Immune-mediated pneumonitis occurred in 4.9% (13/266) of patients receiving OPDIVO: Grade 3 (n=1) and Grade 2 (n=12).
Immune-Mediated Colitis
OPDIVO can cause immune-mediated colitis. Monitor patients for signs and symptoms of colitis. Administer corticosteroids for Grade 2 (of more than 5 days duration), 3, or 4 colitis.

In a separate Phase 3 trial of YERVOY 3 mg/kg, severe, life-threatening, or fatal (diarrhea of ≥7 stools above baseline, fever, ileus, peritoneal signs; Grade 3-5) immune-mediated enterocolitis occurred in 34 (7%) patients. Across all YERVOY-treated patients in that trial (n=511), 5 (1%) developed intestinal perforation, 4 (0.8%) died as a result of complications, and 26 (5%) were hospitalized for severe enterocolitis.
Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Addition of an alternative immunosuppressive agent to the corticosteroid therapy, or replacement of the corticosteroid therapy, should be considered in corticosteroid-refractory immune-mediated colitis if other causes are excluded.
Immune-Mediated Hepatitis
OPDIVO can cause immune-mediated hepatitis. Monitor patients for abnormal liver tests prior to and periodically during treatment.
