New and Long-term Overall Survival Data for KEYTRUDA ^® (pembrolizumab) in Lung Cancer and Melanoma, Plus New Data in Renal Cell, Cervical, Merkel Cell, and Other Cancers

First-Time Lynparza ^® (olaparib) Data in Combination with Abiraterone in Metastatic Prostate Cancer Under Merck and AstraZeneca Strategic Collaboration

New Data in Four Tumor Types Evaluating LENVIMA ^® (lenvatinib) in Combination with KEYTRUDA Under Merck and Eisai Strategic Collaboration

Merck (NYSE:MRK), known as MSD outside the United States and Canada,
today announced that new combination and monotherapy data from Merck’s
oncology portfolio, anchored by anti-PD-1 therapy KEYTRUDA, will be
presented at the 54^th Annual Meeting of the American Society
of Clinical Oncology (ASCO) in Chicago from June 1-5. More than 140
abstracts in over 25 tumor types have been accepted, including new and
long-term data for KEYTRUDA across multiple types of cancer.

“With more data and longer follow-up across tumors and treatment
settings, evidence continues to support the role of KEYTRUDA as a
foundational treatment for many types of cancer,” said Dr. Roger M.
Perlmutter, president, Merck Research Laboratories. “At ASCO, we will
present new and long-term overall survival data for KEYTRUDA in advanced
lung cancer and melanoma – as well as studies across our growing
oncology portfolio in a number of new tumor types where we have adduced
clinically meaningful results.”

The abstracts accepted for the 2018 ASCO Annual Meeting include data for
approved and investigational uses of KEYTRUDA, investigational uses of
PARP inhibitor Lynparza and MEK inhibitor selumetinib (in collaboration
with AstraZeneca), and investigational uses of kinase inhibitor LENVIMA
(in collaboration with Eisai). Highlights to be presented at ASCO
include:

Select Lung Cancer Presentations

• New overall survival (OS) data from the pivotal Phase 3 KEYNOTE-042
  trial with KEYTRUDA monotherapy compared to chemotherapy alone as
  first-line treatment in patients with locally advanced or metastatic
  nonsquamous or squamous non-small cell lung cancer (NSCLC) with a
  PD-L1 tumor proportion score (TPS) of ≥1 percent are to be presented
  in the ASCO opening plenary session and press program on Sunday, June
  3 (Abstract #LBA4). As previously announced, an interim
  analysis conducted by the independent Data Monitoring Committee (DMC)
  demonstrated that treatment with KEYTRUDA monotherapy resulted in
  significantly longer overall survival (OS) than that achieved with
  platinum-based chemotherapy (carboplatin plus paclitaxel or
  carboplatin plus pemetrexed) in patients with a PD-L1 TPS of ≥1
  percent.
• First-time data of an early patient cohort (n=204) from the
  randomized, double-blind, placebo-controlled, Phase 3 KEYNOTE-407
  trial investigating KEYTRUDA in combination with
  carboplatin-paclitaxel or nab-paclitaxel, compared with
  carboplatin-paclitaxel or nab-paclitaxel alone as first-line treatment
  in patients with metastatic squamous NSCLC (Abstract #105) are to be
  presented. An interim analysis of pre-specified secondary endpoints
  showed an alpha-controlled, overall response rate (ORR) of 58.4
  percent for KEYTRUDA plus chemotherapy (n=101) compared to 35 percent
  for chemotherapy alone (n=103) (p-value, 0.0004) [(7.7 months median
  follow-up (range 0.4, 13.9)]. The duration of response (DOR) was ≥6
  months in 65.8 percent of patients receiving KEYTRUDA plus
  chemotherapy compared to 45.6 percent receiving chemotherapy alone.
  Adverse events (grade ≥3) were 64.4 percent for KEYTRUDA plus
  chemotherapy and 74.5 percent for chemotherapy alone. No new safety
  concerns were reported. The primary endpoints of the study are OS and
  progression-free survival (PFS). As previously announced, based on
  these data, Merck has recently submitted a supplemental Biologics
  License Application (sBLA) to the U.S. Food and Drug Administration
  (FDA).

Select Combination Data Presentations

• First-time data from a Phase 2 trial in post-chemotherapy, metastatic
  castration-resistant prostate cancer with Lynparza in combination with
  standard of care, abiraterone, regardless of HRRm status (Abstract
  #5003) are to be featured as an oral presentation. This is the first
  data for a PARP inhibitor in combination with standard of care,
  abiraterone, in the treatment of prostate cancer.
• New and updated data for KEYTRUDA in combination with LENVIMA are to
  be presented including in advanced hepatocellular carcinoma (HCC),
  endometrial carcinoma, head and neck squamous cell carcinoma (HNSCC)
  and renal cell carcinoma (RCC) from the KEYNOTE-524 (Study 116) and
  Phase 1b/2 KEYNOTE-146 (Study 111) studies (Abstracts #4076, #5596,
  #6016 and #4560, respectively). KEYTRUDA in combination with LENVIMA
  was previously granted Breakthrough Therapy Designation for the
  potential treatment of advanced and/or metastatic RCC.

Select Monotherapy Data Presentations

• Long-term (four- and five-year) OS data from KEYNOTE-006 and
  KEYNOTE-001 in advanced melanoma with KEYTRUDA monotherapy (Abstracts
  #9503 and #9516, respectively) are to be presented.
• First-time and long-term data for KEYTRUDA monotherapy are to be
  presented in eight tumor types. These data are in esophageal cancer
  (KEYNOTE-180, Abstract #4049), HCC (KEYNOTE-224, Abstract #4020),
  Merkel cell carcinoma (KEYNOTE-017, Abstract #9506), RCC (KEYNOTE-427,
  Abstract #4500), prostate cancer (KEYNOTE-199, Abstract #5007),
  ovarian cancer (KEYNOTE-100, Abstract #5511), cervical cancer
  (KEYNOTE-158, Abstract #5522) and small cell lung cancer (KEYNOTE-158,
  Abstract #8506).

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 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
(pembrolizumab).

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 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 (pembrolizumab) 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.

Microsatellite Instability-High (MSI-H) Cancer

KEYTRUDA is indicated for the treatment of adult and pediatric patients
with unresectable or metastatic microsatellite instability-high (MSI-H)
or mismatch repair deficient (dMMR) solid tumors that have progressed
following prior treatment and who have no satisfactory alternative
treatment options, or colorectal cancer that has progressed following
treatment with fluoropyrimidine, oxaliplatin, and irinotecan.

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. The safety and
effectiveness of KEYTRUDA in pediatric patients with MSI-H central
nervous system cancers have not been established.

In adult patients with MSI-H cancer, 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. In
children with MSI-H cancer, 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.

Gastric Cancer

KEYTRUDA is indicated for the treatment of patients with recurrent
locally advanced or metastatic gastric or gastroesophageal junction
(GEJ) adenocarcinoma whose tumors express PD-L1 [Combined Positive Score
(CPS) ≥1] as determined by an FDA-approved test, with disease
progression on or after two or more prior lines of therapy including
fluoropyrimidine- and platinum-containing chemotherapy and if
appropriate, HER2/neu-targeted 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. The recommended dose of KEYTRUDA is 200 mg every
three weeks until disease progression, 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
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
appetite (31% vs 23%), headache (31% vs 16%), cough (24% vs 18%),
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%).

About Lynparza

^®

(olaparib) tablets, 150mg

Lynparza is a first-in-class poly ADP-ribose polymerase (PARP)
inhibitor and the first targeted treatment to potentially exploit tumor
DNA damage response (DDR)-pathway deficiencies to preferentially kill
cancer cells. Specifically, in vitro studies have shown that
Lynparza-induced cytotoxicity may involve inhibition of PARP enzymatic
activity and increased formation of PARP-DNA complexes, resulting in DNA
damage and cancer cell death.

Indications for Lynparza



in the U.S.

Lynparza is a poly (ADP-ribose) polymerase (PARP) inhibitor indicated:

For the maintenance treatment of adult patients with recurrent
epithelial ovarian, fallopian tube, or primary peritoneal cancer, who
are in complete or partial response to platinum-based chemotherapy.

For the treatment of adult patients with deleterious or suspected
deleterious germline BRCA-mutated (gBRCAm) advanced
ovarian cancer who have been treated with 3 or more prior lines of
chemotherapy. Select patients for therapy based on an FDA-approved
companion diagnostic for Lynparza.

In patients with deleterious or suspected deleterious gBRCAm, human
epidermal growth factor receptor 2 (HER2)-negative metastatic breast
cancer who have previously been treated with chemotherapy in the
neoadjuvant, adjuvant or metastatic setting. Patients with hormone
receptor (HR)-positive breast cancer should have been treated with a
prior endocrine therapy or be considered inappropriate for endocrine
treatment. Select patients for therapy based on an FDA-approved
companion diagnostic for Lynparza.

Important Safety Information for Lynparza

Contraindications

There are no contraindications for Lynparza.

Warnings and Precautions

Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML): Occurred
in <1.5% of patients exposed to Lynparza monotherapy, and the majority
of events had a fatal outcome. The duration of therapy in patients who
developed secondary MDS/AML varied from <6 months to >2 years. All of
these patients had previous chemotherapy with platinum agents and/or
other DNA-damaging agents, including radiotherapy, and some also had a
history of more than one primary malignancy or of bone marrow dysplasia.

Do not start Lynparza until patients have recovered from hematological
toxicity caused by previous chemotherapy (≤Grade 1). Monitor complete
blood count for cytopenia at baseline and monthly thereafter for
clinically significant changes during treatment. For prolonged
hematological toxicities, interrupt Lynparza and monitor blood count
weekly until recovery.

If the levels have not recovered to Grade 1 or less after 4 weeks, refer
the patient to a hematologist for further investigations, including bone
marrow analysis and blood sample for cytogenetics. Discontinue Lynparza
(olaparib) if MDS/AML is confirmed.

Pneumonitis: Occurred in <1% of patients exposed to Lynparza, and
some cases were fatal. If patients present with new or worsening
respiratory symptoms such as dyspnea, cough, and fever, or a
radiological abnormality occurs, interrupt Lynparza treatment and
initiate prompt investigation. Discontinue Lynparza if pneumonitis is
confirmed and treat patient appropriately.

Embryo-Fetal Toxicity: Based on its mechanism of action and
findings in animals, Lynparza can cause fetal harm. A pregnancy test is
recommended for females of reproductive potential prior to initiating
treatment.

Females

Advise females of reproductive potential of the potential risk to a
fetus and to use effective contraception during treatment and for 6
months following the last dose.

Males

Advise male patients with female partners of reproductive potential or
who are pregnant to use effective contraception during treatment and for
3 months following the last dose of Lynparza and to not donate sperm
during this time.

were: decrease in hemoglobin (82%), decrease in lymphocytes (73%),
decrease in leukocytes (71%), increase in mean corpuscular volume (71%),
decrease in absolute neutrophil count (46%), and decrease in platelets
(33%).

Drug Interactions

Anticancer Agents: Clinical studies of Lynparza in combination
with other myelosuppressive anticancer agents, including DNA-damaging
agents, indicate a potentiation and prolongation of myelosuppressive
toxicity.

CYP3A Inhibitors: Avoid concomitant use of strong or moderate
CYP3A inhibitors. If a strong or moderate CYP3A inhibitor must be
co-administered, reduce the dose of Lynparza. Advise patients to avoid
grapefruit, grapefruit juice, Seville oranges, and Seville orange juice
during Lynparza treatment.

CYP3A Inducers: Avoid concomitant use of strong or moderate CYP3A
inducers when using Lynparza (olaparib). If a moderate inducer cannot be
avoided, there is a potential for decreased efficacy of Lynparza.

Use in Specific Populations

Lactation: No data are available regarding the presence of
olaparib in human milk, its effects on the breastfed infant or on milk
production. Because of the potential for serious adverse reactions in
the breastfed infant, advise a lactating woman not to breastfeed during
treatment with Lynparza and for 1 month after receiving the final dose.

Pediatric Use: The safety and efficacy of Lynparza have not been
established in pediatric patients.

Hepatic Impairment: No adjustment to the starting dose is
required in patients with mild hepatic impairment (Child-Pugh
classification A). There are no data in patients with moderate or severe
hepatic impairment.

Renal Impairment: No adjustment to the starting dose is necessary
in patients with mild renal impairment (CLcr=51-80 mL/min). In patients
with moderate renal impairment (CLcr=31-50 mL/min), reduce the dose to
200 mg twice daily. There are no data in patients with severe renal
impairment or end-stage renal disease (CLcr ≤30 mL/min).

Dosing and Administration

To avoid substitution errors and overdose, do not substitute Lynparza
tablets with Lynparza capsules on a milligram-to-milligram basis
due to differences in the dosing and bioavailability of each
formulation. Recommended tablet dose is 300 mg, taken orally twice
daily, with or without food. Continue treatment until disease
progression or unacceptable toxicity. For adverse reactions, consider
dose interruption or dose reduction.

About LENVIMA

^® 

(lenvatinib)

LENVIMA^® (lenvatinib) is a kinase inhibitor that is indicated
for:

• Differentiated Thyroid Cancer (DTC): single agent for patients with
  locally recurrent or metastatic, progressive, radioactive
  iodine-refractory DTC.
• Renal Cell Cancer (RCC): in combination with everolimus for patients
  with advanced RCC following one prior anti-angiogenic therapy.

Lenvatinib, discovered and developed by Eisai, is a receptor tyrosine
kinase (RTK) inhibitor that inhibits the kinase activities of vascular
endothelial growth factor (VEGF) receptors VEGFR1 (FLT1), VEGFR2 (KDR),
and VEGFR3 (FLT4). Lenvatinib also inhibits other RTKs that have been
implicated in pathogenic angiogenesis, tumor growth, and cancer
progression in addition to their normal cellular functions, including
fibroblast growth factor (FGF) receptors FGFR1-4; the platelet derived
growth factor receptor alpha (PDGFRα), KIT, and RET

Important Safety Information

Warnings and Precautions

• In DTC, hypertension was reported in 73% of patients on LENVIMA vs 16%
  with placebo (44% vs 4% grade ≥3). In RCC, hypertension was reported
  in 42% of patients on LENVIMA + everolimus vs 10% with everolimus
  alone (13% vs 2% grade 3). Serious complications of poorly controlled
  hypertension, including aortic dissection, have been reported.
  Systolic blood pressure ≥160 mmHg occurred in 29% of patients, and 21%
  of patients had a diastolic blood pressure ≥100 mmHg in the LENVIMA +
  everolimus–treated group. Blood pressure should be controlled prior to
  treatment and monitored throughout. Withhold dose for grade 3
  hypertension despite optimal antihypertensive therapy; resume at
  reduced dose when controlled at grade ≤2. Discontinue for
  life-threatening hypertension
• In DTC, cardiac dysfunction was reported in 7% of patients on LENVIMA
  vs 2% with placebo (2% vs 0% grade ≥3). In RCC, decreased ejection
  fraction and cardiac failure were reported in 10% of patients on
  LENVIMA + everolimus vs 6% with everolimus alone (3% vs 2% grade 3).
  Monitor for signs/symptoms of cardiac decompensation. Withhold LENVIMA
  for development of grade 3 cardiac dysfunction until improvement to
  grade 0, 1, or baseline. Resume at reduced dose or discontinue based
  on severity and persistence of cardiac dysfunction. Discontinue for
  grade 4 cardiac dysfunction

  dose when diarrhea resolves to grade 1 or baseline. Permanently
  discontinue LENVIMA for grade 4 diarrhea despite medical management
• In DTC, events of renal impairment were reported in 14% of patients on
  LENVIMA vs 2% with placebo (3% vs 1% grade ≥3). In RCC, events of
  renal impairment were reported in 18% of patients on LENVIMA +
  everolimus vs 12% with everolimus alone (10% vs 2% grade ≥3). Withhold
  LENVIMA for grade 3 or 4 renal failure/impairment. Resume at reduced
  dose or discontinue, depending on severity/persistence of renal
  impairment. Active management of diarrhea and any other
  gastrointestinal (GI) symptoms should be initiated for grade 1 events
• In DTC, events of GI perforation or fistula were reported in 2% of
  patients on LENVIMA vs 0.8% with placebo. In RCC, events of GI
  perforation, abscess, or fistula (grade ≥3) were reported in 2% of
  patients on LENVIMA + everolimus vs 0% with everolimus alone.
  Discontinue in patients who develop GI perforation or life-threatening
  fistula
• In DTC, QT/QTc interval prolongation was reported in 9% of patients on
  LENVIMA vs 2% with placebo (2% vs 0% >500 ms). In RCC, QTc interval
  increases >60 ms were reported in 11% of patients on LENVIMA +
  everolimus (6% >500 ms) vs 0% with everolimus alone. Monitor
  electrocardiograms in patients with congenital long QT syndrome,
  congestive heart failure, bradyarrhythmias, or patients taking drugs
  known to prolong the QT interval. Monitor and correct electrolyte
  abnormalities in all patients. Withhold dose for QTc interval
  prolongation >500 ms. Resume at reduced dose when QTc prolongation
  resolves to baseline
• In DTC, hypocalcemia (grade ≥3) was reported in 9% of patients on
  LENVIMA vs 2% with placebo. In RCC, hypocalcemia (grade ≥3) was
  reported in 6% of patients on LENVIMA + everolimus vs 2% with
  everolimus alone. Monitor blood calcium levels at least monthly and
  replace calcium as necessary. Interrupt and adjust LENVIMA as necessary
• Across clinical studies in which 1,160 patients received LENVIMA
  monotherapy, reversible posterior leukoencephalopathy syndrome (RPLS)
  was reported in 4 patients. Withhold LENVIMA for RPLS until fully
  resolved. Resume at reduced dose or discontinue based on the severity
  and persistence of neurologic symptoms
• Across clinical studies in which 1,160 patients received LENVIMA
  monotherapy, hemorrhage (grade ≥3) was reported in 2% of patients. In
  DTC, hemorrhagic events occurred in 35% of patients on LENVIMA vs 18%
  with placebo (2% vs 3% grade ≥3). There was 1 fatal intracranial
  hemorrhage case among 16 patients who received LENVIMA and had central
  nervous system metastases at baseline. The most frequently reported
  hemorrhagic event was epistaxis (11% grade 1, 1% grade 2).
  Discontinuation due to hemorrhagic events occurred in 1% of patients
  on LENVIMA. In RCC, hemorrhagic events occurred in 34% of patients on
  LENVIMA + everolimus vs 26% with everolimus alone (8% vs 2% grade ≥3).
  The most frequently reported hemorrhagic event was epistaxis (23% for
  LENVIMA + everolimus vs 24% with everolimus alone). There was 1 fatal
  cerebral hemorrhage case. Discontinuation due to hemorrhagic events
  occurred in 3% of patients on LENVIMA + everolimus. Consider the risk
  of severe or fatal hemorrhage associated with tumor
  invasion/infiltration of major blood vessels (eg, carotid artery).
  Withhold LENVIMA for the development of grade 3 hemorrhage until
  resolved to grade 0 or 1. Resume at reduced dose or discontinue based
  on severity/persistence of hemorrhage. Discontinue for grade 4
  hemorrhage
• In DTC patients with normal baseline thyroid-stimulating hormone
  (TSH), elevation of TSH level above 0.5 mU/L was observed postbaseline
  in 57% of patients on LENVIMA vs 14% with placebo. In RCC, grade 1 or
  2 hypothyroidism occurred in 24% of patients on LENVIMA + everolimus
  vs 2% with everolimus alone. In RCC patients with normal or low TSH at
  baseline, elevation of TSH was observed postbaseline in 60% of
  patients on LENVIMA + everolimus vs 3% with everolimus alone. Monitor
  thyroid function before initiation of and at least monthly throughout
  treatment. Treat hypothyroidism according to standard medical practice
  to maintain a euthyroid state
• Impaired wound healing, including fistula formation, has been reported
  in patients receiving LENVIMA. Temporary interruption of LENVIMA
  therapy should be considered in patients undergoing major surgical
