Bristol-Myers Squibb Announces Phase 3 CheckMate -498 Study Did Not Meet Primary Endpoint of Overall Survival with Opdivo (nivolumab) Plus Radiation in Patients with Newly Diagnosed MGMT-Unmethylated Glioblastoma Multiforme
May 9, 2019PRINCETON, N.J.–(BUSINESS WIRE)–lt;a href="https://twitter.com/search?q=%24BMY&src=ctag" target="_blank"gt;$BMYlt;/agt; lt;a href="https://twitter.com/hashtag/BMS?src=hash" target="_blank"gt;#BMSlt;/agt;–Bristol-Myers
Squibb Company (NYSE: BMY) today announced the Phase 3 CheckMate
-498 trial evaluating Opdivo (nivolumab) plus radiation versus
temozolomide plus radiation in patients with newly diagnosed
O6-methylguanine-DNA methyltransferase (MGMT)-unmethylated glioblastoma
multiforme (GBM) did not meet its primary endpoint of overall survival
(OS) at final analysis. The safety profile of Opdivo was
consistent with previously reported studies in solid tumors. The Company
will complete a full evaluation of the data from CheckMate -498 and work
with investigators on the future presentation and publication of the
results.
“While we are disappointed the CheckMate -498 trial did not meet its
primary endpoint, GBM is a notoriously aggressive cancer,” said Fouad
Namouni, M.D., head, oncology development, Bristol-Myers Squibb. “We are
grateful to all those who participated in this trial and remain
committed to researching the potential of immunotherapy to address the
important unmet medical need of patients who suffer from this
devastating disease.”
Opdivo is also being studied in patients with newly diagnosed
MGMT-methylated GBM in the Phase 3 CheckMate -548 (NCT02667587) study,
in which Opdivo is added to the current standard of care,
radiation plus temozolomide.
About CheckMate -498
CheckMate -498 (NCT02617589) is a Phase 3 randomized, multi-center study
evaluating Opdivo and radiation versus temozolomide and radiation
in patients with newly diagnosed MGMT-unmethylated GBM. After surgery,
patients in the experimental arm received Opdivo every two weeks
concurrent with radiation, followed by maintenance with Opdivo every
four weeks until disease progression or unacceptable toxicity. The
primary endpoint of the trial was OS. Secondary endpoints included
progression-free survival, and OS rate at two years.
About Glioblastoma Multiforme
Glioblastoma multiforme (GBM) is the most common and most aggressive
type of primary malignant tumor of the central nervous system. Globally,
an estimated 300,000 patients develop, and 241,000 patients die from,
brain or central nervous system cancer each year. Standard treatment for
patients with newly diagnosed GBM can include surgery followed by
radiation and chemotherapy, but treatment options are limited. The last
investigational medicine to improve survival for patients with newly
diagnosed GBM was approved by the U.S. Food and Drug Administration in
2005. The five year survival rate of patients with GBM is less than five
percent.
MGMT methylation status is the most commonly used biomarker in
GBM and, studies suggest, may be predictive of the likelihood of
patients with GBM to respond to alkylating chemotherapy such as
temozolomide. Patients with MGMT-unmethylated GBM are generally known to
have a worse prognosis than patients with MGMT-methylated GBM.

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 enrolled more than 25,000 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 a separate Phase 3 study 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 study (n=511), 5
(1%) developed intestinal perforation, 4 (0.8%) died as a result of
complications, and 26 (5%) were hospitalized for severe enterocolitis.
Immune-Mediated Hepatitis
OPDIVO can cause immune-mediated hepatitis. Monitor patients for
abnormal liver tests prior to and periodically during treatment.
Administer corticosteroids for Grade 2 or greater transaminase
elevations. For patients without HCC, withhold OPDIVO for Grade 2 and
permanently discontinue OPDIVO for Grade 3 or 4. For patients with HCC,
withhold OPDIVO and administer corticosteroids if AST/ALT is within
normal limits at baseline and increases to >3 and up to 5 times the
upper limit of normal (ULN), if AST/ALT is >1 and up to 3 times ULN at
baseline and increases to >5 and up to 10 times the ULN, and if AST/ALT
is >3 and up to 5 times ULN at baseline and increases to >8 and up to 10
times the ULN. Permanently discontinue OPDIVO and administer

with neurologic symptoms may include, but not be limited to,
consultation with a neurologist, brain MRI, and lumbar puncture.
Withhold OPDIVO in patients with new-onset moderate to severe neurologic
signs or symptoms and evaluate to rule out other causes. If other
etiologies are ruled out, administer corticosteroids and permanently
discontinue OPDIVO for immune-mediated encephalitis. In patients
receiving OPDIVO monotherapy, encephalitis occurred in 0.2% (3/1994) of
patients. Fatal limbic encephalitis occurred in one patient after 7.2
months of exposure despite discontinuation of OPDIVO and administration
of corticosteroids. Encephalitis occurred in one patient receiving
OPDIVO 1 mg/kg with YERVOY 3 mg/kg (0.2%) after 1.7 months of
exposure. Encephalitis occurred in one RCC patient receiving OPDIVO 3
mg/kg with YERVOY 1 mg/kg (0.2%) after approximately 4 months of
exposure. Encephalitis occurred in one MSI-H/dMMR mCRC patient (0.8%)
receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg after 15 days of exposure.
Other Immune-Mediated Adverse Reactions
Based on the severity of the adverse reaction, permanently discontinue
or withhold OPDIVO, administer high-dose corticosteroids, and, if
appropriate, initiate hormone-replacement therapy. Across clinical
trials of OPDIVO monotherapy or in combination with YERVOY, the
following clinically significant immune-mediated adverse reactions, some
with fatal outcome, occurred in <1.0% of patients receiving OPDIVO:
myocarditis, rhabdomyolysis, myositis, uveitis, iritis, pancreatitis,
facial and abducens nerve paresis, demyelination, polymyalgia
rheumatica, autoimmune neuropathy, Guillain-Barré syndrome,
hypopituitarism, systemic inflammatory response syndrome, gastritis,
duodenitis, sarcoidosis, histiocytic necrotizing lymphadenitis (Kikuchi
lymphadenitis), motor dysfunction, vasculitis, aplastic anemia,
pericarditis, and myasthenic syndrome.
If uveitis occurs in combination with other immune-mediated adverse
reactions, consider a Vogt-Koyanagi-Harada-like syndrome, which has been
observed in patients receiving OPDIVO and may require treatment with
systemic steroids to reduce the risk of permanent vision loss.
