Bristol-Myers Squibb and Incyte to Advance the Combination of Opdivo (nivolumab) and Epacadostat into First-line Registrational Trials

NEW YORK & WILMINGTON, Del.–(BUSINESS WIRE)– Bristol-Myers
Squibb Company (NYSE:BMY) and Incyte
Corporation (Nasdaq:INCY) today announced the companies have agreed
to advance their clinical development program evaluating the combination
of epacadostat, Incyte’s investigational oral selective IDO1 enzyme
inhibitor, with Opdivo
(nivolumab), Bristol-Myers Squibb’s PD-1 immune checkpoint inhibitor,
into phase 3 registrational studies in first-line non-small cell lung
cancer across the spectrum of PD-L1 expression and first-line head and
neck cancer. Additionally, the companies are expanding the ECHO-204
Phase 1/2 study, established under a collaboration between the companies
in 2014, to include anti-PD-1/PD-L1 relapsed/refractory melanoma
cohorts. The expanded clinical development program, including the phase
3 registrational studies, will be co-funded by the two companies.

“We are pleased to build upon our existing collaboration with Incyte and
advance the clinical development of epacadostat combined with Opdivo
into phase 3 registrational trials,” said Fouad Namouni, M.D., head of
Development, Oncology, Bristol-Myers Squibb. “Incyte shares our goal of
improving clinical outcomes for patients with some of the
hardest-to-treat cancers, and we look forward to working together on
studies evaluating the clinical outcomes of this therapeutic
combination.”

“We are very pleased to expand our partnership with Bristol-Myers Squibb
and move the combination of epacadostat plus Opdivo forward into
pivotal studies,” said Steven Stein, M.D., Chief Medical Officer,
Incyte. “We believe that further expanding the ECHO development program
for epacadostat, including the initiation of these new Phase 3 trials,
will bring us closer to our goal of providing new treatment options for
patients with certain cancers.”

About Epacadostat (INCB024360)

Indoleamine 2,3-dioxygenase 1 (IDO1) is a key immunosuppressive enzyme
that modulates the anti-tumor immune response by promoting regulatory T
cell generation and blocking effector T cell activation, thereby
facilitating tumor growth by allowing cancer cells to avoid immune
surveillance. Epacadostat is a first-in-class, highly potent and
selective oral inhibitor of the IDO1 enzyme that is designed to reverse
tumor-associated immune suppression and restore effective anti-tumor
immune responses. In single-arm studies, the combination of epacadostat
and immune checkpoint inhibitors has shown proof-of-concept in patients
with unresectable or metastatic melanoma.

About the Opdivo Clinical Development Program

Bristol-Myers Squibb’s global development program founded on scientific
expertise in the field of Immuno-Oncology includes a broad range of
clinical trials studying Opdivo, 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.

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 57 countries, including the United
States, the European Union and Japan. 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 47 countries, including the United States and the
European Union.

ulceration, or necrotic, bullous, or hemorrhagic manifestations; Grade
3-5) occurred in 13 (2.5%) patients. 1 (0.2%) patient died as a result
of toxic epidermal necrolysis. 1 additional patient required
hospitalization for severe dermatitis.

Immune-Mediated Encephalitis

OPDIVO can cause immune-mediated encephalitis. Evaluation of patients
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 with YERVOY (0.2%) after 1.7 months of exposure.

Other Immune-Mediated Adverse Reactions

Based on the severity of adverse reaction, permanently discontinue or
withhold treatment, administer high-dose corticosteroids, and, if
appropriate, initiate hormone-replacement therapy. Across clinical
trials of OPDIVO the following clinically significant immune-mediated
adverse reactions occurred in <1.0% of patients receiving OPDIVO:
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), myositis, myocarditis,
rhabdomyolysis, motor dysfunction, vasculitis, and myasthenic syndrome.

Infusion Reactions

OPDIVO can cause severe infusion reactions, which have been reported in
<1.0% of patients in clinical trials. Discontinue OPDIVO in patients
with Grade 3 or 4 infusion reactions. Interrupt or slow the rate of
infusion in patients with Grade 1 or 2. In patients receiving OPDIVO
monotherapy, infusion-related reactions occurred in 6.4% (127/1994) of
patients. In patients receiving OPDIVO with YERVOY, infusion-related
reactions occurred in 2.5% (10/407) of patients.

Complications of Allogeneic HSCT after OPDIVO

Complications, including fatal events, occurred in patients who received
allogeneic HSCT after OPDIVO. Outcomes were evaluated in 17 patients
from Checkmate 205 and 039, who underwent allogeneic HSCT after
discontinuing OPDIVO (15 with reduced-intensity conditioning, 2 with
myeloablative conditioning). Thirty-five percent (6/17) of patients died
from complications of allogeneic HSCT after OPDIVO. Five deaths occurred
in the setting of severe or refractory GVHD. Grade 3 or higher acute
GVHD was reported in 29% (5/17) of patients. Hyperacute GVHD was
reported in 20% (n=2) of patients. A steroid-requiring febrile syndrome,
without an identified infectious cause, was reported in 35% (n=6) of
patients. Two cases of encephalitis were reported: Grade 3 (n=1)
lymphocytic encephalitis without an identified infectious cause, and
Grade 3 (n=1) suspected viral encephalitis. Hepatic veno-occlusive
disease (VOD) occurred in one patient, who received reduced-intensity
conditioned allogeneic HSCT and died of GVHD and multi-organ failure.
Other cases of hepatic VOD after reduced-intensity conditioned
allogeneic HSCT have also been reported in patients with lymphoma who
received a PD-1 receptor blocking antibody before transplantation. Cases
of fatal hyperacute GVHD have also been reported. These complications
may occur despite intervening therapy between PD-1 blockade and
allogeneic HSCT.

Follow patients closely for early evidence of transplant-related
complications such as hyperacute GVHD, severe (Grade 3 to 4) acute GVHD,
steroid-requiring febrile syndrome, hepatic VOD, and other
immune-mediated adverse reactions, and intervene promptly.

Embryo-Fetal Toxicity

Based on their mechanisms of action, OPDIVO and YERVOY 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 an OPDIVO- or YERVOY-
containing regimen and for at least 5 months after the last dose of
OPDIVO.

Lactation

It is not known whether OPDIVO or YERVOY 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 an OPDIVO-containing regimen, advise women to discontinue
breastfeeding during treatment. Advise women to discontinue nursing
during treatment with YERVOY and for 3 months following the final dose.
