- Study to evaluate potential of
CB-839 plus Opdivo to target immune-suppressive cells in the tumor
microenvironment
Bristol-Myers Squibb Company (NYSE:BMY) and Calithera
Biosciences, Inc. (Nasdaq:CALA), a clinical stage biotechnology
company focused on discovering and developing novel small molecule
drugs directed against tumor metabolism and tumor immunology
targets for the treatment of cancer, today announced a clinical
trial collaboration to evaluate Bristol-Myers Squibb’s Opdivo in
combination with Calithera’s CB-839 in patients with clear cell
renal cell carcinoma (ccRCC). CB-839 is an orally administered
glutaminase inhibitor currently in Phase 1/2 clinical studies.
Preclinical data suggest that CB-839, which is designed to
target a pathway to starve tumor cells of the key nutrient
glutamine, may enhance the effects of checkpoint inhibitors and may
also reverse tumor resistance to checkpoint inhibitors by altering
the immune-suppressive microenvironment and promoting an anti-tumor
immune response. Opdivo is designed to overcome immune
suppression. The companies will explore the potential of combining
these two agents with the goal of achieving improved and sustained
efficacy in ccRCC patients with cancer that is stable or growing on
a PD-1 inhibitor therapy.
“Influencing the tumor microenvironment remains a key area of
focus of research, and we are excited to explore the potential
benefits of Opdivo plus CB-839 in an effort to advance new
combination therapies for difficult to treat cancers,” said Fouad
Namouni, M.D., senior vice president, head of Oncology Development,
Bristol-Myers Squibb.
“The combination with Opdivo follows our strategy to combine
CB-839 with therapies to improve outcomes for RCC patients,” said
Susan Molineaux, CEO of Calithera Biosciences. “We believe that by
blocking glutamine consumption in tumors, and redirecting this key
nutrient for cell growth and proliferation to T-cells, CB-839 could
enhance the effects of Opdivo. With support from Bristol-Myers
Squibb, Calithera is excited to advance this combination into the
Phase 2 portion of CX-839-004, our ongoing study in ccRCC
patients.”
Opdivo was the first PD-1 immune checkpoint inhibitor to receive
regulatory approval anywhere in the world in July 2014, and
currently has regulatory approval in 54 countries
including the United States, Japan, and in
the European Union.
Bristol-Myers Squibb &
Immuno-Oncology: Advancing Oncology Research
At Bristol-Myers Squibb, we have a vision for the future of
cancer care that is focused on Immuno-Oncology, now considered a
major treatment choice alongside surgery, radiation, chemotherapy
and targeted therapies for certain types of cancer.
We have a comprehensive clinical portfolio of investigational
and approved Immuno-Oncology agents, many of which were discovered
and developed by our scientists. Our ongoing Immuno-Oncology
clinical program is looking at broad patient populations, across
multiple solid tumors and hematologic malignancies, and lines of
therapy and histologies, with the intent of powering our trials for
overall survival and other important measures like durability of
response. We pioneered the research leading to the first regulatory
approval for the combination of two Immuno-Oncology agents and
continue to study the role of combinations in cancer.
We are also investigating other immune system pathways in the
treatment of cancer including CTLA-4, CD-137, KIR, SLAMF7, PD-1,
GITR, CSF1R, IDO and LAG-3. These pathways may lead to potential
new treatment options – in combination or monotherapy – to help
patients fight different types of cancers.
Our collaboration with academia, as well as small and large
biotech and pharmaceutical companies, to research the potential of
Immuno-Oncology and non-Immuno-Oncology combinations helps achieve
our goal of providing new treatment options in clinical
practice.
At Bristol-Myers Squibb, we are committed to changing survival
expectations in hard-to-treat cancers and the way patients live
with cancer.
About Opdivo
Cancer cells may exploit “regulatory” pathways, such as
checkpoint pathways, to hide from the immune system and shield the
tumor from immune attack. Opdivo is a PD-1 immune checkpoint
inhibitor that binds to the checkpoint receptor PD-1 expressed on
activated T-cells, and blocks the binding of PD-L1 and PD-L2,
preventing the PD-1 pathway’s suppressive signaling on the immune
system, including the interference with an anti-tumor immune
response.
Opdivo’s broad global development program is based on
Bristol-Myers Squibb’s understanding of the biology behind
Immuno-Oncology. Our company is at the forefront of researching the
potential of Immuno-Oncology to extend survival in hard-to-treat
cancers. This scientific expertise serves as the basis for the
Opdivo development program, which includes a broad range of Phase 3
clinical trials evaluating overall survival as the primary endpoint
across a variety of tumor types. The Opdivo trials have also
contributed toward the clinical and scientific understanding of the
role of biomarkers and how patients may benefit from Opdivo across
the continuum of PD-L1 expression. To date, the Opdivo clinical
development program has enrolled more than 18,000 patients.

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.
