The expanded collaboration now includes seven pivotal
studies:
- A Phase 3 study in metastatic melanoma
(trial underway);
- two Phase 3 studies in first-line
NSCLC, including both PD-L1 high-expressing and PD-L1 unselected
populations;
- two Phase 3 studies in bladder cancer,
including one in first-line bladder cancer and one in second-line
bladder cancer;
- a Phase 3 study in first-line RCC;
and
- a Phase 3 study in first-line
SCCHN.
Incyte and Merck will share responsibilities for funding these
pivotal studies, and Merck will be responsible for conducting the
trials.
“We are pleased to announce further details of our collaboration
with Merck and to be moving forward with multiple Phase 3 studies
in these four additional tumor types as quickly as possible,” said
Steven Stein, M.D., Chief Medical Officer, Incyte. “We look forward
to our continued clinical collaboration, the initiation of these
additional pivotal trials and to further exploring the potential of
this novel immune-therapy combination as a treatment for patients
with cancer.”
“Our clinical trial program with Incyte represents an important
part of our multi-pronged efforts to investigate the potential for
KEYTRUDA (pembrolizumab) in combination with promising compounds,
such as epacadostat,” said Dr. Roy Baynes, senior vice president,
head of clinical development, and Chief Medical Officer, Merck
Research Laboratories. “Through these trials, our long-term goal is
to help make a difference in the lives of people with a wide range
of cancers.”
About ECHO
The ECHO clinical trial program was established to investigate
the efficacy and safety of epacadostat as a core component of
combination therapy in oncology. Ongoing Phase 1 and Phase 2
studies evaluating epacadostat in combination with PD-1 and PD-L1
inhibitors collectively plan to enroll over 900 patients in a broad
range of solid tumor types as well as hematological malignancies.
ECHO-301 (NCT02752074), a Phase 3 randomized, double-blind,
placebo-controlled study investigating KEYTRUDA in combination with
epacadostat or placebo for the first-line treatment of patients
with advanced or metastatic melanoma, is also underway.
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 reverses tumor-associated immune suppression and
restores 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. In these studies, epacadostat combined with
the CTLA-4 inhibitor ipilimumab or the PD-1 inhibitor KEYTRUDA
improved response rates compared with studies of the immune
checkpoint inhibitors alone.
About KEYTRUDA® (pembrolizumab)
KEYTRUDA is a humanized monoclonal antibody that works by
increasing the ability of the body’s immune system to help detect
and fight tumor cells. KEYTRUDA blocks the interaction between PD-1
and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes
which may affect both tumor cells and healthy cells.
KEYTRUDA is administered as an intravenous infusion over 30
minutes every three weeks for the approved indications. KEYTRUDA
for injection is supplied in a 100 mg single-dose vial.
KEYTRUDA (pembrolizumab) Indications and
Dosing
Melanoma
KEYTRUDA is indicated for the treatment of patients with
unresectable or metastatic melanoma at a dose of 2 mg/kg every
three weeks until disease progression or unacceptable toxicity.
Lung Cancer
KEYTRUDA (pembrolizumab) is indicated for the first-line
treatment of patients with metastatic non-small cell lung cancer
(NSCLC) whose tumors have high PD-L1 expression [tumor proportion
score (TPS) ≥50%] as determined by an FDA-approved test, with no
EGFR or ALK genomic tumor aberrations.
KEYTRUDA is also indicated for the treatment of patients with
metastatic NSCLC whose tumors express PD-L1 (TPS ≥1%) as determined
by an FDA-approved test, with disease progression on or after
platinum-containing chemotherapy. Patients with EGFR or ALK genomic
tumor aberrations should have disease progression on FDA-approved
therapy for these aberrations prior to receiving KEYTRUDA.
In metastatic NSCLC, KEYTRUDA is administered at a fixed dose of
200 mg every three weeks until disease progression, unacceptable
toxicity, or up to 24 months in patients without disease
progression.
Head and Neck Cancer
KEYTRUDA is indicated for the treatment of patients with
recurrent or metastatic head and neck squamous cell carcinoma
(HNSCC) with disease progression on or after platinum-containing
chemotherapy. This indication is approved under accelerated
approval based on tumor response rate and durability of response.
Continued approval for this indication may be contingent upon
verification and description of clinical benefit in the
confirmatory trials. In HNSCC, KEYTRUDA is administered at a fixed
dose of 200 mg every three weeks until disease progression,
unacceptable toxicity, or up to 24 months in patients without
disease progression.
Classical Hodgkin Lymphoma
KEYTRUDA is indicated for the treatment of adult and pediatric
patients with refractory classical Hodgkin lymphoma (cHL), or who
have relapsed after three or more prior lines of therapy. This
indication is approved under accelerated approval based on tumor
response rate and durability of response. Continued approval for
this indication may be contingent upon verification and description
of clinical benefit in the confirmatory trials. In adults with cHL,
KEYTRUDA is administered at a fixed dose of 200 mg every three
weeks until disease progression or unacceptable toxicity, or up to
24 months in patients without disease progression. In pediatric
patients with cHL, KEYTRUDA is administered at a dose of 2 mg/kg
(up to a maximum of 200 mg) every three weeks until disease
progression or unacceptable toxicity, or up to 24 months in
patients without disease progression.
Selected Important Safety Information for
KEYTRUDA® (pembrolizumab)
KEYTRUDA can cause immune-mediated pneumonitis, including fatal
cases. Pneumonitis occurred in 94 (3.4%) of 2799 patients receiving
KEYTRUDA, including Grade 1 (0.8%), 2 (1.3%), 3 (0.9%), 4 (0.3%),
and 5 (0.1%) pneumonitis, and occurred more frequently in patients
with a history of prior thoracic radiation (6.9%) compared to those
without (2.9%). Monitor patients for signs and symptoms of
pneumonitis. Evaluate suspected pneumonitis with radiographic
imaging. Administer corticosteroids for Grade 2 or greater
pneumonitis. Withhold KEYTRUDA (pembrolizumab) for Grade 2;
permanently discontinue KEYTRUDA for Grade 3 or 4 or recurrent
Grade 2 pneumonitis.
KEYTRUDA can cause immune-mediated colitis. Colitis occurred in
48 (1.7%) of 2799 patients receiving KEYTRUDA, including Grade 2
(0.4%), 3 (1.1%), and 4 (<0.1%) colitis. Monitor patients for
signs and symptoms of colitis. Administer corticosteroids for Grade
2 or greater colitis. Withhold KEYTRUDA for Grade 2 or 3;
permanently discontinue KEYTRUDA for Grade 4 colitis.
KEYTRUDA can cause immune-mediated hepatitis. Hepatitis occurred
in 19 (0.7%) of 2799 patients receiving KEYTRUDA, including Grade 2
(0.1%), 3 (0.4%), and 4 (<0.1%) hepatitis. Monitor patients for
changes in liver function. Administer corticosteroids for Grade 2
or greater hepatitis and, based on severity of liver enzyme
elevations, withhold or discontinue KEYTRUDA.
KEYTRUDA can cause hypophysitis. Hypophysitis occurred in 17
(0.6%) of 2799 patients receiving KEYTRUDA, including Grade 2
(0.2%), 3 (0.3%), and 4 (<0.1%) hypophysitis. Monitor patients
for signs and symptoms of hypophysitis (including hypopituitarism
and adrenal insufficiency). Administer corticosteroids and hormone
replacement as clinically indicated. Withhold KEYTRUDA for Grade 2;
withhold or discontinue for Grade 3 or 4 hypophysitis.
KEYTRUDA can cause thyroid disorders, including hyperthyroidism,
hypothyroidism, and thyroiditis. Hyperthyroidism occurred in 96
(3.4%) of 2799 patients receiving KEYTRUDA, including Grade 2
(0.8%) and 3 (0.1%) hyperthyroidism. Hypothyroidism occurred in 237
(8.5%) of 2799 patients receiving KEYTRUDA, including Grade 2
(6.2%) and 3 (0.1%) hypothyroidism. The incidence of new or
worsening hypothyroidism was higher in patients with HNSCC,
occurring in 28 (15%) of 192 patients with HNSCC, including Grade 3
(0.5%) hypothyroidism. Thyroiditis occurred in 16 (0.6%) of 2799
patients receiving KEYTRUDA, including Grade 2 (0.3%) thyroiditis.
Monitor patients for changes in thyroid function (at the start of
treatment, periodically during treatment, and as indicated based on
clinical evaluation) and for clinical signs and symptoms of thyroid
disorders. Administer replacement hormones for hypothyroidism and
manage hyperthyroidism with thionamides and beta-blockers as
appropriate. Withhold or discontinue KEYTRUDA for Grade 3 or 4
hyperthyroidism.
KEYTRUDA can cause type 1 diabetes mellitus, including diabetic
ketoacidosis, which have been reported in 6 (0.2%) of 2799
patients. Monitor patients for hyperglycemia or other signs and
symptoms of diabetes. Administer insulin for type 1 diabetes, and
withhold KEYTRUDA and administer antihyperglycemics in patients
with severe hyperglycemia.
KEYTRUDA can cause immune-mediated nephritis. Nephritis occurred
in 9 (0.3%) of 2799 patients receiving KEYTRUDA, including Grade 2
(0.1%), 3 (0.1%), and 4 (<0.1%) nephritis. Monitor patients for
changes in renal function. Administer corticosteroids for Grade 2
or greater nephritis. Withhold KEYTRUDA for Grade 2; permanently
discontinue KEYTRUDA for Grade 3 or 4 nephritis.
KEYTRUDA can cause other clinically important immune-mediated
adverse reactions. For suspected immune-mediated adverse reactions,
ensure adequate evaluation to confirm etiology or exclude other
causes. Based on the severity of the adverse reaction, withhold
KEYTRUDA and administer corticosteroids. Upon improvement to Grade
1 or less, initiate corticosteroid taper and continue to taper over
at least 1 month. Based on limited data from clinical studies in
patients whose immune-related adverse reactions could not be
controlled with corticosteroid use, administration of other
systemic immunosuppressants can be considered. Resume KEYTRUDA
(pembrolizumab) when the adverse reaction remains at Grade 1 or
less following corticosteroid taper. Permanently discontinue
KEYTRUDA for any Grade 3 immune-mediated adverse reaction that
recurs and for any life-threatening immune-mediated adverse
reaction.
The following clinically significant immune-mediated adverse
reactions occurred in less than 1% (unless otherwise indicated) of
2799 patients: arthritis (1.5%), exfoliative dermatitis, bullous
pemphigoid, rash (1.4%), uveitis, myositis, Guillain-Barré
syndrome, myasthenia gravis, vasculitis, pancreatitis, hemolytic
anemia, and partial seizures arising in a patient with inflammatory
foci in brain parenchyma. In addition, myelitis and myocarditis
were reported in other clinical trials, including cHL, and
postmarketing use.
Solid organ transplant rejection has been reported in
postmarketing use of KEYTRUDA. Treatment with KEYTRUDA may increase
the risk of rejection in solid organ transplant recipients.
Consider the benefit of treatment with KEYTRUDA vs the risk of
possible organ rejection in these patients.
KEYTRUDA can cause severe or life-threatening infusion-related
reactions, which have been reported in 6 (0.2%) of 2799 patients.
Monitor patients for signs and symptoms of infusion-related
reactions, including rigors, chills, wheezing, pruritus, flushing,
rash, hypotension, hypoxemia, and fever. For Grade 3 or 4
reactions, stop infusion and permanently discontinue KEYTRUDA.
Immune-mediated complications, including fatal events, occurred
in patients who underwent allogeneic hematopoietic stem cell
transplantation (HSCT) after being treated with KEYTRUDA. Of 23
patients with cHL who proceeded to allogeneic HSCT after treatment
with KEYTRUDA on any trial, 6 patients (26%) developed
graft-versus-host-disease (GVHD), one of which was fatal, and 2
patients (9%) developed severe hepatic veno-occlusive disease (VOD)
after reduced-intensity conditioning, one of which was fatal. Cases
of fatal hyperacute GVHD after allogeneic HSCT have also been
reported in patients with lymphoma who received a PD-1
receptor-blocking antibody before transplantation. 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.
Based on its mechanism of action, KEYTRUDA can cause fetal harm
when administered to a pregnant woman. If used during pregnancy, or
if the patient becomes pregnant during treatment, apprise the
patient of the potential hazard to a fetus. Advise females of
reproductive potential to use highly effective contraception during
treatment and for 4 months after the last dose of KEYTRUDA.
In KEYNOTE-006, KEYTRUDA was discontinued due to adverse
reactions in 9% of 555 patients with advanced melanoma; adverse
reactions leading to discontinuation in more than one patient were
colitis (1.4%), autoimmune hepatitis (0.7%), allergic reaction
(0.4%), polyneuropathy (0.4%), and cardiac failure (0.4%). Adverse
reactions leading to interruption of KEYTRUDA occurred in 21% of
patients; the most common (≥1%) was diarrhea (2.5%). The most
common adverse reactions with KEYTRUDA vs ipilimumab were fatigue
(28% vs 28%), diarrhea (26% with KEYTRUDA), rash (24% vs 23%), and
nausea (21% with KEYTRUDA). Corresponding incidence rates are
listed for ipilimumab only for those adverse reactions that
occurred at the same or lower rate than with KEYTRUDA
(pembrolizumab).
KEYTRUDA was discontinued due to adverse reactions in 8% of 682
patients with metastatic NSCLC. The most common adverse event
resulting in permanent discontinuation of KEYTRUDA was pneumonitis
(1.8%). Adverse reactions leading to interruption of KEYTRUDA
occurred in 23% of patients; the most common (≥1%) were diarrhea
(1%), fatigue (1.3%), pneumonia (1%), liver enzyme elevation
(1.2%), decreased appetite (1.3%), and pneumonitis (1%). The most
common adverse reactions (occurring in at least 20% of patients and
at a higher incidence than with docetaxel) were decreased appetite
(25% vs 23%), dyspnea (23% vs 20%), and nausea (20% vs 18%).
KEYTRUDA was discontinued due to adverse reactions in 17% of 192
patients with HNSCC. Serious adverse reactions occurred in 45% of
patients. The most frequent serious adverse reactions reported in
at least 2% of patients were pneumonia, dyspnea, confusional state,
vomiting, pleural effusion, and respiratory failure. The most
common adverse reactions (reported in at least 20% of patients)
were fatigue, decreased appetite, and dyspnea. Adverse reactions
occurring in patients with HNSCC were generally similar to those
occurring in patients with melanoma or NSCLC, with the exception of
increased incidences of facial edema (10% all Grades; 2.1% Grades 3
or 4) and new or worsening hypothyroidism.
KEYTRUDA was discontinued due to adverse reactions in 5% of 210
patients with cHL and treatment was interrupted due to adverse
reactions in 26% of patients. Fifteen percent (15%) of patients had
an adverse reaction requiring systemic corticosteroid therapy.
Serious adverse reactions occurred in 16% of patients. The most
frequent serious adverse reactions (≥1%) included pneumonia,
pneumonitis, pyrexia, dyspnea, GVHD, and herpes zoster. Two
patients died from causes other than disease progression; one from
GVHD after subsequent allogeneic HSCT and one from septic shock.
The most common adverse reactions (occurring in ≥20% of patients)
were fatigue (26%), pyrexia (24%), cough (24%), musculoskeletal
pain (21%), diarrhea (20%), and rash (20%).
It is not known whether KEYTRUDA is excreted in human milk.
Because many drugs are excreted in human milk, instruct women to
discontinue nursing during treatment with KEYTRUDA and for 4 months
after the final dose.
There is limited experience in pediatric patients. In a study of
40 pediatric patients with advanced melanoma, PD-L1–positive
advanced, relapsed, or refractory solid tumors or lymphoma,
patients were treated with KEYTRUDA for a median of 43 days (range
1 to 414 days), with 24 patients (60%) receiving treatment for 42
days or more. The safety profile in pediatric patients was similar
to that seen in adults treated with KEYTRUDA. Toxicities that
occurred at a higher rate (≥15% difference) in these patients when
compared to adults under 65 years of age were fatigue (45%),
vomiting (38%), abdominal pain (28%), hypertransaminasemia (28%),
and hyponatremia (18%).
