April 23, 2018 3:30 pm ET

Merck (NYSE: MRK), known as MSD outside the United States and Canada,
today announced that following validation by the European Medicines
Agency (EMA), the centralized review process has begun for the company’s
Type II Variation, which seeks approval for KEYTRUDA, Merck’s anti-PD-1
therapy, in combination with pemetrexed (ALIMTA®) and
platinum chemotherapy (cisplatin or carboplatin) for the first-line
treatment of patients with metastatic nonsquamous non-small cell lung
cancer (NSCLC). The application was accepted for review based on overall
survival (OS) and progression-free survival (PFS) data from the Phase 3
KEYNOTE-189 trial, which were recently presented at the American
Association of Cancer Research (AACR) 2018 Annual Meeting and published
simultaneously in The New England Journal of Medicine. If
approved by the EMA, this would mark the third indication for KEYTRUDA
in metastatic NSCLC to be approved in Europe based on overall survival
data.

“EMA’s acceptance of our application for review is based on data from
the Phase 3 KEYNOTE-189 trial, which showed first-line treatment with
KEYTRUDA in combination with pemetrexed and platinum chemotherapy
significantly prolonged overall survival compared to chemotherapy alone
in patients with metastatic nonsquamous non-small cell lung cancer,
regardless of PD-L1 expression,” said Dr. Roger M. Perlmutter,
president, Merck Research Laboratories. “We are very pleased that the
centralized review process is underway, and are hopeful that this new
combination regimen will soon become available for appropriate patients
in Europe who have been diagnosed with metastatic lung cancer.”

About KEYTRUDA

® 

(pembrolizumab)
Injection 100mg


KEYTRUDA is an anti-PD-1 therapy that works by
increasing the ability of the body’s immune system to help detect and
fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that
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.

Merck has the industry’s largest immuno-oncology clinical research
program, which currently involves more than 750 trials studying KEYTRUDA
across a wide variety of cancers and treatment settings. The KEYTRUDA
clinical program seeks to understand the role of KEYTRUDA across cancers
and the factors that may predict a patient’s likelihood of benefitting
from treatment with KEYTRUDA, including exploring several different
biomarkers.

KEYTRUDA (pembrolizumab) Indications and Dosing in the U.S.

Melanoma

KEYTRUDA is indicated for the treatment of patients
with unresectable or metastatic melanoma at a fixed dose of 200 mg every
three weeks until disease progression or unacceptable toxicity.

Lung Cancer

KEYTRUDA, as a single agent, 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, as a single agent, 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.

KEYTRUDA, in combination with pemetrexed and carboplatin, is indicated
for the first-line treatment of patients with metastatic nonsquamous
NSCLC. This indication is approved under accelerated approval based on
tumor response rate and progression-free survival. Continued approval
for this indication may be contingent upon verification and description
of clinical benefit in the confirmatory trials.

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.

When administering KEYTRUDA in combination with chemotherapy, KEYTRUDA
should be administered prior to chemotherapy when given on the same day.
See also the Prescribing Information for pemetrexed and carboplatin.

Selected Important Safety Information for KEYTRUDA

®


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
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.

Immune-mediated rashes, including Stevens-Johnson syndrome (SJS), toxic
epidermal necrolysis (TEN) (some cases with fatal outcome), exfoliative
dermatitis, and bullous pemphigoid, can occur. Monitor patients for
suspected severe skin reactions and based on the severity of the adverse
reaction, withhold or permanently discontinue KEYTRUDA and administer
corticosteroids. For signs or symptoms of SJS or TEN, withhold KEYTRUDA
and refer the patient for specialized care for assessment and treatment.
If SJS or TEN is confirmed, permanently discontinue KEYTRUDA.

KEYTRUDA can cause other clinically important immune-mediated adverse
reactions. These immune-mediated reactions may occur in any organ
system. 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 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%), 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 classical Hodgkin lymphoma, 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, including hypersensitivity and anaphylaxis, 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.

In clinical trials in patients with multiple myeloma, the addition of
KEYTRUDA to a thalidomide analogue plus dexamethasone resulted in
increased mortality. Treatment of these patients with a PD-1 or PD-L1
blocking antibody in this combination is not recommended outside of
controlled clinical trials.

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.

In KEYNOTE-010, KEYTRUDA monotherapy 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%).

In KEYNOTE-021(G1), when KEYTRUDA was administered in combination with
carboplatin and pemetrexed (carbo/pem) in advanced nonsquamous NSCLC,
KEYTRUDA was discontinued in 10% of 59 patients. The most common adverse
reaction resulting in discontinuation of KEYTRUDA (≥2%) was acute kidney
injury (3.4%). Adverse reactions leading to interruption of KEYTRUDA
occurred in 39% of patients; the most common (≥2%) were fatigue (8%),
neutrophil count decreased (8%), anemia (5%), dyspnea (3.4%), and
pneumonitis (3.4%). The most common adverse reactions (≥20%) with
KEYTRUDA compared to carbo/pem alone were fatigue (71% vs 50%), nausea
(68% vs 56%), constipation (51% vs 37%), rash (42% vs 21%), vomiting
(39% vs 27%), dyspnea (39% vs 21%), diarrhea (37% vs 23%), decreased

dizziness (24% vs 16%), insomnia (24% vs 15%), pruritus (24% vs 4.8%),
peripheral edema (22% vs 18%), dysgeusia (20% vs 11%), alopecia (20% vs
3.2%), upper respiratory tract infection (20% vs 3.2%), and arthralgia
(15% vs 24%). This study was not designed to demonstrate a statistically
significant difference in adverse reaction rates for KEYTRUDA as
compared to carbo/pem alone for any specified adverse reaction.

In KEYNOTE-012, 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.

In KEYNOTE-087, 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%).

In KEYNOTE-052, KEYTRUDA was discontinued due to adverse reactions in
11% of 370 patients with locally advanced or metastatic urothelial
carcinoma. The most common adverse reactions (in ≥20% of patients) were
fatigue (38%), musculoskeletal pain (24%), decreased appetite (22%),
constipation (21%), rash (21%), and diarrhea (20%). Eighteen patients
(5%) died from causes other than disease progression. Five patients
(1.4%) who were treated with KEYTRUDA experienced sepsis which led to
death, and 3 patients (0.8%) experienced pneumonia which led to death.
Adverse reactions leading to interruption of KEYTRUDA occurred in 22% of
patients; the most common (≥1%) were liver enzyme increase, diarrhea,
urinary tract infection, acute kidney injury, fatigue, joint pain, and
pneumonia. Serious adverse reactions occurred in 42% of patients, the
most frequent (≥2%) of which were urinary tract infection, hematuria,
acute kidney injury, pneumonia, and urosepsis.

In KEYNOTE-045, KEYTRUDA was discontinued due to adverse reactions in 8%
of 266 patients with locally advanced or metastatic urothelial
carcinoma. The most common adverse reaction resulting in permanent
discontinuation of KEYTRUDA was pneumonitis (1.9%). Adverse reactions
leading to interruption of KEYTRUDA occurred in 20% of patients; the
most common (≥1%) were urinary tract infection (1.5%), diarrhea (1.5%),
and colitis (1.1%). The most common adverse reactions (≥20%) in patients
who received KEYTRUDA vs those who received chemotherapy were fatigue
(38% vs 56%), musculoskeletal pain (32% vs 27%), pruritus (23% vs 6%),
decreased appetite (21% vs 21%), nausea (21% vs 29%), and rash (20% vs
13%). Serious adverse reactions occurred in 39% of KEYTRUDA-treated
patients, the most frequent (≥2%) of which were urinary tract infection,
pneumonia, anemia, and pneumonitis.

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, 40
pediatric patients (16 children aged 2 years to younger than 12 years
and 24 adolescents aged 12 years to 18 years) with advanced melanoma,
lymphoma, or PD-L1–positive advanced, relapsed, or refractory solid
tumors were administered KEYTRUDA 2 mg/kg every 3 weeks. Patients
received KEYTRUDA for a median of 3 doses (range 1–17 doses), with 34
patients (85%) receiving KEYTRUDA for 2 doses or more. The safety
profile in these 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%).
