Bristol-Myers Squibb Company (NYSE:BMY) today announced that Opdivo (nivolumab) is the first PD-1 inhibitor to demonstrate superior overall survival versus standard of care (docetaxel) in an open-label, randomized.
Phase III study (CheckMate -057) evaluating previously-treated patients with advanced, non-squamous non-small cell lung cancer (NSCLC). A 27% reduction in the risk of progression or death – the primary study endpoint – was reported for Opdivo (n=292) versus docetaxel (n=290) based upon a hazard ratio of 0.73 (96% CI, 0.59-0.89; P = 0.0015).
Opdivo was associated with a doubling of overall median survival across the continuum of PD-L1 expression, starting at 1% level of expression, in the trial. The safety profile of Opdivo in CheckMate -057 was favorable versus docetaxel with grade 3–5 treatment-related adverse events reported in 10% of patients who were treated with Opdivo versus 54% in the docetaxel arm. These data will be featured today, May 29, during the 51st Annual Meeting of the American Society of Clinical Oncology (ASCO) press briefing at 1:00 – 2:00 PM CDT and presented during a clinical science symposium on Saturday, May 30 from 8:51 – 9:03 AM CDT (Late Breaking Abstract #109).
“CheckMate -057 results reported today mark a milestone in the development of new treatment options for lung cancer, as Opdivo is the first PD-1 inhibitor to show a significant improvement in overall survival in a Phase III trial in non-squamous non-small cell lung cancer compared with the current standard of care, docetaxel,” said Luis Paz-Ares, MD, Hospital Universitario Doce de Octubre, Madrid, Spain. “Our goal with clinical cancer research is to always look for new options that may improve upon, or in some cases replace, current standard of care. The CheckMate -057 results represent progress toward establishing a new standard of care that may replace docetaxel in PD-L1 expressers.”
Lung cancer is the leading cause of cancer deaths globally, resulting in more than 1.5 million deaths each year, according to the World Health Organization. Lung cancer results in more deaths worldwide than colorectal, breast and prostate cancers combined. Non-small cell lung cancer is one of the most common types of the disease and accounts for approximately 85% of cases. Survival rates vary depending on the stage and type of the cancer when it is diagnosed.
“The survival results from this Phase III trial, as well as from CheckMate -017 in squamous NSCLC, validate the Bristol-Myers Squibb development strategy for Opdivo to improve survival expectations for patients with lung cancer,” said Michael Giordano, senior vice president, Head of Development, Oncology, Bristol-Myers Squibb. “The CheckMate -057 results defined the role for PD-L1 expression, based upon an overall survival endpoint and showed that patients whose tumor expressed PD-L1 at 1% or greater levels achieved a doubling of overall survival. This represents a significant scientific advance in non-small cell lung cancer.”
About CheckMate -057
CheckMate -057 is a landmark Phase III, open-label, randomized clinical trial that evaluated patients with advanced non-squamous NSCLC who had progressed during or after one prior platinum doublet-based chemotherapy regimen. The trial included patients regardless of their PD-L1 status. Secondary endpoints included objective response rate, progression-free survival and efficacy by tumor PD-L1 expression. Patients enrolled in the trial were administered Opdivo 3 mg/kg every two weeks versus standard of care, docetaxel, at 75 mg/m2 every three weeks.
In addition to improving overall survival, Opdivo demonstrated a superior objective response rate of 19% versus 12% for docetaxel (P = 0.0246). The median duration of response for Opdivo was 17.2 months versus 5.6 months for docetaxel, and median time to response of 2.1 months vs. 2.6 months, respectively.
Proven Efficacy Across Histologies in Lung Cancer
CheckMate -057 is the second positive Phase III trial to demonstrate superior overall survival for Opdivo in non-small cell lung cancer. Earlier this year, the Phase III CheckMate -017 trial was stopped early due to superior overall survival versus docetaxel in previously-treated advanced squamous non-small cell lung cancer and formed the basis of the company’s first indication in lung cancer from the U.S. Food & Drug Administration’s (FDA) approval for Opdivo. Trial results from CheckMate -017 will be presented at ASCO during an oral abstract session on Sunday, May 31 from 4:30 – 4:42 PM CDT (Abstract #8009).
Bristol-Myers Squibb has a broad, global development program to study Opdivo in multiple tumor types consisting of more than 50 trials – as monotherapy or in combination with other therapies – in which more than 8,000 patients have been enrolled worldwide.
Opdivo became the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world on July 4, 2014 when Ono Pharmaceutical Co. announced that it received manufacturing and marketing approval in Japan for the treatment of patients with unresectable melanoma. In the U.S., the FDA granted its first approval for Opdivo for the treatment of patients with unresectable or metastatic melanoma and disease progression following Yervoy (ipilimumab) and, if BRAF V600 mutation positive, a BRAF inhibitor. On March 4, 2015, Opdivo received its second FDA approval for the treatment of patients with metastatic squamous non-small cell lung cancer (NSCLC) with progression on or after platinum-based chemotherapy.
IMPORTANT SAFETY INFORMATION
• Severe pneumonitis or interstitial lung disease, including fatal cases, occurred with OPDIVO treatment. Across the clinical trial experience in 691 patients with solid tumors, fatal immune-mediated pneumonitis occurred in 0.7% (5/691) of patients receiving OPDIVO; no cases occurred in Trial 3. In Trial 3, immune-mediated pneumonitis occurred in 6% (7/117) of patients receiving OPDIVO including five Grade 3 and two Grade 2 cases. Monitor patients for signs and symptoms of pneumonitis. Administer corticosteroids for Grade 2 or greater pneumonitis. Permanently discontinue OPDIVO for Grade 3 or 4 and withhold OPDIVO until resolution for Grade 2.
• In Trial 3, diarrhea occurred in 21% (24/117) of patients receiving OPDIVO. Grade 3 immune-mediated colitis occurred in 0.9% (1/117) of patients. Monitor patients for immune-mediated colitis. Administer corticosteroids for Grade 2 (of more than 5 days duration), 3, or 4 colitis. Withhold OPDIVO for Grade 2 or 3. Permanently discontinue OPDIVO for Grade 4 colitis or recurrent colitis upon restarting OPDIVO.
• In Trial 3, the incidences of increased liver test values were AST (16%), alkaline phosphatase (14%), ALT (12%), and total bilirubin (2.7%). Monitor patients for abnormal liver tests prior to and periodically during treatment. Administer corticosteroids for Grade 2 or greater transaminase elevations. Withhold OPDIVO for Grade 2 and permanently discontinue OPDIVO for Grade 3 or 4 immune-mediated hepatitis.
Immune-Mediated Nephritis and Renal Dysfunction
• In Trial 3, the incidence of elevated creatinine was 22%. Immune-mediated renal dysfunction (Grade 2) occurred in 0.9% (1/117) of patients. Monitor patients for elevated serum creatinine prior to and periodically during treatment. For Grade 2 or 3 serum creatinine elevation, withhold OPDIVO and administer corticosteroids; if worsening or no improvement occurs, permanently discontinue OPDIVO. Administer corticosteroids for Grade 4 serum creatinine elevation and permanently discontinue OPDIVO.
Immune-Mediated Hypothyroidism and Hyperthyroidism
• In Trial 3, hypothyroidism occurred in 4.3% (5/117) of patients receiving OPDIVO. Hyperthyroidism occurred in 1.7% (2/117) of patients including one Grade 2 case. Monitor thyroid function prior to and periodically during treatment. Administer hormone replacement therapy for hypothyroidism. Initiate medical management for control of hyperthyroidism.
Immune-Mediated Adverse Reactions
• The following clinically significant immune-mediated adverse reactions occurred in <2% of OPDIVO-treated patients: adrenal insufficiency, uveitis, pancreatitis, facial and abducens nerve paresis, demyeliniation, autoimmune neuropathy, motor dysfunction and vasculitis. Across clinical trials of OPDIVO administered at doses 3 mg/kg and 10 mg/kg, additional clinically significant, immune-mediated adverse reactions were identified: hypophysitis, diabetic ketoacidosis, hypopituitarism, Guillain-Barré syndrome, and myasthenic syndrome. Based on the severity of adverse reaction, withhold OPDIVO, administer high-dose corticosteroids, and, if appropriate, initiate hormone- replacement therapy.
• Based on its mechanism of action, OPDIVO can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO and for at least 5 months after the last dose of OPDIVO.
• It is not known whether OPDIVO is present in human milk. Because many drugs, including antibodies, are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from OPDIVO, advise women to discontinue breastfeeding during treatment.
Serious Adverse Reactions
• In Trial 3, serious adverse reactions occurred in 59% of patients receiving OPDIVO. The most frequent serious adverse drug reactions reported in ≥2% of patients were dyspnea, pneumonia, chronic obstructive pulmonary disease exacerbation, pneumonitis, hypercalcemia, pleural effusion, hemoptysis, and pain.
Common Adverse Reactions
• The most common adverse reactions (≥20%) reported with OPDIVO in Trial 3 were fatigue (50%), dyspnea (38%), musculoskeletal pain (36%), decreased appetite (35%), cough (32%), nausea (29%), and constipation (24%).
