Data Supporting Application to Be Presented at 2017 ASCO Annual Meeting

KENILWORTH, N.J.–(BUSINESS WIRE)–Merck (NYSE:MRK), known as MSD outside the United States and Canada,
announced today that the U.S. Food and Drug Administration (FDA) has
accepted for review a supplemental Biologics License Application (sBLA)
for KEYTRUDA® (pembrolizumab), the company’s anti-PD-1
therapy, seeking approval for treatment of patients with recurrent or
advanced gastric or gastroesophageal junction adenocarcinoma who have
already received two or more lines of chemotherapy. The FDA granted
Priority Review with a PDUFA, or target action, date of Sept. 22, 2017.

“An estimated nearly one-hundred-thousand people are living with gastric
cancer in the U.S., yet little progress has been made in bringing
forward new treatment options to these patients for whom chemotherapy
has long been the standard of care,” said Dr. Roger Dansey, senior vice
president and therapeutic area head, oncology late-stage development,
Merck Research Laboratories. “We look forward to working with the FDA to
bring KEYTRUDA to people with gastric cancer who have progressed after
receiving chemotherapy and are in urgent need of another option.”

The application submitted to the FDA is seeking approval for KEYTRUDA
monotherapy in previously treated patients at a fixed dose of 200 mg
administered intravenously every three weeks. The application is based
on data from cohort one of the phase 2 KEYNOTE-059 trial investigating
KEYTRUDA in heavily pretreated patients with recurrent or advanced
gastric or gastroesophageal junction adenocarcinoma that has progressed
after two or more lines of chemotherapy. Data from cohort one of
KEYNOTE-059 will be presented at the 53rd Annual Meeting of the American
Society of Clinical Oncology (ASCO) in Chicago, June 2 – 6, 2017 during
an oral session on Sunday, June 4 at 9:00 a.m. – 9:12 a.m. CDT
(Location: Hall D2).

Merck is committed to investigating new approaches across the spectrum
of cancers with more than 500 clinical trials evaluating KEYTRUDA
(pembrolizumab) in more than 30 tumor types, including multiple
gastrointestinal cancers like gastric cancer. Specific to gastric
cancer, Merck’s broad clinical development program encompasses all
stages of advanced disease and is investigating KEYTRUDA as monotherapy
and in combination with other cancer treatments across multiple lines of
therapy. To date, the program includes four gastric cancer
registration-enabling studies and numerous other gastrointestinal cancer
studies are underway.

About Gastric Cancer

Gastric cancer, also called stomach cancer, is a type of cancer that
begins in the stomach and tends to develop slowly over many years. Most
gastric cancers are adenocarcinomas, which develop from the cells of the
innermost lining (mucosa) of the stomach. Risk factors for gastric
cancer include gender, age, ethnicity, geography and infection with Helicobacter
pylori
. Worldwide, gastric cancer is the fifth most common type of
cancer and the third leading cause of cancer death. Each year there are
approximately 952,000 newly diagnosed cases of gastric cancer resulting
in approximately 723,000 deaths worldwide. It is estimated that in 2017,
more than 10,000 people will die from gastric cancer in the U.S. alone.

About KEYTRUDA

®

(pembrolizumab) Injection

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.

Studies of KEYTRUDA – from the largest immuno-oncology program in the
industry with more than 500 trials – include a wide variety of cancers
and treatment settings. The KEYTRUDA clinical program seeks to
understand factors that predict a patient’s likelihood of benefitting
from treatment with KEYTRUDA, including the exploration of several
different biomarkers across a broad range of tumors.

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 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.

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
(pembrolizumab) 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.

Urothelial Carcinoma

KEYTRUDA is indicated for the treatment of patients with locally
advanced or metastatic urothelial carcinoma who are not eligible for
cisplatin-containing chemotherapy. This indication is approved under
accelerated approval based on tumor response rate and duration of
response. Continued approval for this indication may be contingent upon
verification and description of clinical benefit in the confirmatory
trials.

KEYTRUDA is also indicated for the treatment of patients with locally
advanced or metastatic urothelial carcinoma who have disease progression
during or following platinum-containing chemotherapy or within 12 months
of neoadjuvant or adjuvant treatment with platinum-containing
chemotherapy.

In locally advanced or metastatic urothelial carcinoma, 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.

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. 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 (pembrolizumab) 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 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 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 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.

Based on its mechanism of action, KEYTRUDA (pembrolizumab) 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

arthralgia (15% vs 24%). The study was not designed to demonstrate a
statistically significant difference in adverse reaction rates for
KEYTRUDA plus chemotherapy, as compared to chemotherapy alone, for any
specified adverse reaction.

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

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 (pembrolizumab) was discontinued due to adverse

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%),

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 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%).
