Merck’s KEYTRUDA® (pembrolizumab) Approved in China for First-Line Treatment of Metastatic Nonsquamous Non-Small Cell Lung Cancer (NSCLC) in Combination with Chemotherapy
April 1, 2019
KEYTRUDA is First Anti-PD-1 Therapy to be Approved in Multiple Tumor
Types in China
KENILWORTH, N.J.–(BUSINESS WIRE)–lt;a href="https://twitter.com/search?q=%24MRK&src=ctag" target="_blank"gt;$MRKlt;/agt; lt;a href="https://twitter.com/hashtag/MRK?src=hash" target="_blank"gt;#MRKlt;/agt;–Merck (NYSE: MRK), known as MSD outside the United States and Canada,
today announced that KEYTRUDA, Merck’s anti-PD-1 therapy, has been
approved by the National Medical Products Administration (NMPA) in
combination with pemetrexed and platinum chemotherapy for the first-line
treatment of patients with metastatic nonsquamous non-small cell lung
cancer (NSCLC), with no EGFR or ALK genomic tumor aberrations. This new
indication was granted conditional approval based on overall survival
(OS) and progression-free survival (PFS) data from the pivotal Phase 3
KEYNOTE-189 trial in patients regardless of PD-L1 tumor expression
status. Continued approval may be contingent upon verification and
description of clinical benefit in Chinese patients in a confirmatory
trial. With this approval, KEYTRUDA is the first anti-PD-1 therapy
approved for more than one tumor type in China, following its initial
approval in July 2018 for advanced melanoma, and the first anti-PD-1
therapy approved in the first-line treatment setting for metastatic
nonsquamous NSCLC.
“Lung cancer is a deadly disease and the leading cause of cancer deaths
in China, claiming the lives of more than 626,000 people in our country
each year,” said Prof. Yi-Long Wu, honorary director of the Guangdong
Lung Cancer Research Institute, and tenured director of Guangdong
Provincial People’s Hospital. “The approval of KEYTRUDA in combination
with standard chemotherapy for the first-line treatment of metastatic
nonsquamous non-small cell lung cancer is an important milestone in the
treatment of advanced lung cancer in China.”
In KEYNOTE-189, KEYTRUDA in combination with pemetrexed and platinum
chemotherapy resulted in a statistically significant and clinically
meaningful improvement in OS (HR=0.49 [95% CI, 0.38-0.64]; p<0.00001),
reducing the risk of death by half compared to chemotherapy alone. The
study also showed a significant improvement in PFS compared to
chemotherapy alone (HR=0.52 [95% CI, 0.43-0.64]; p<0.00001).
“This approval represents a key advance in a country with a high
incidence of lung cancer, and where significant progress for the
first-line treatment of this devastating disease has been very limited
over a number of years,” said Dr. Roy Baynes, senior vice president and
head of global clinical development, chief medical officer, Merck
Research Laboratories. “This also means that, based on the results of
KEYNOTE-189, KEYTRUDA in combination with chemotherapy has now been
approved in the U.S., Europe, Japan and China, among other countries,
for the first-line treatment of appropriate patients with metastatic
nonsquamous non-small cell lung cancer.”
“We are committed to developing innovative therapies and introducing
them as quickly as possible to physicians and patients in China,” said
Joseph Romanelli, president of MSD in China. “Patients with metastatic
nonsquamous non-small cell lung cancer in China now have a new option
for the first-line treatment of their disease, and we will continue to
collaborate with the Chinese government, healthcare organizations and
our business partners to improve patient access to KEYTRUDA in 2019.”
About Lung Cancer in China
Lung cancer, which forms in the tissues of the lungs, usually within
cells lining the air passages, is the leading cause of cancer death in
China and worldwide. Each year, more than 782,000 new cases of lung
cancer are diagnosed in China and more than 626,000 deaths result from
the disease. The two main types of lung cancer are non-small cell and
small cell. Non-small cell lung cancer (NSCLC) is the most common type
of lung cancer, accounting for about 85 percent of all cases. There are
several subtypes of NSCLC, including adenocarcinoma (accounting for 40%
of lung cancers), squamous cell carcinoma (25 to 30%) and large cell
carcinoma (10 to 15%).
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. There are currently more than 900 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.

Selected Important Safety Information for KEYTRUDA
Immune-Mediated Pneumonitis
KEYTRUDA can cause immune-mediated pneumonitis, including fatal cases.
Pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA,
including Grade 1 (0.8%), 2 (1.3%), 3 (0.9%), 4 (0.3%), and 5 (0.1%),
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.
Immune-Mediated Colitis
KEYTRUDA can cause immune-mediated colitis. Colitis occurred in 1.7%
(48/2799) of patients receiving KEYTRUDA, including Grade 2 (0.4%), 3
(1.1%), and 4 (<0.1%). 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.
Immune-Mediated Hepatitis
KEYTRUDA can cause immune-mediated hepatitis. Hepatitis occurred in 0.7%
(19/2799) of patients receiving KEYTRUDA, including Grade 2 (0.1%), 3
(0.4%), and 4 (<0.1%). 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.
Immune-Mediated Endocrinopathies
KEYTRUDA can cause hypophysitis, thyroid disorders, and type 1 diabetes
mellitus. Hypophysitis occurred in 0.6% (17/2799) of patients, including
Grade 2 (0.2%), 3 (0.3%), and 4 (<0.1%). Hypothyroidism occurred in 8.5%
(237/2799) of patients, including Grade 2 (6.2%) and 3 (0.1%). The
incidence of new or worsening hypothyroidism was higher in patients with
HNSCC, occurring in 15% (28/192) of patients. Hyperthyroidism occurred
in 3.4% (96/2799) of patients, including Grade 2 (0.8%) and 3 (0.1%),
and thyroiditis occurred in 0.6% (16/2799) of patients, including Grade
2 (0.3%). Type 1 diabetes mellitus, including diabetic ketoacidosis,
occurred in 0.2% (6/2799) of patients.
Monitor patients for signs and symptoms of hypophysitis (including
hypopituitarism and adrenal insufficiency), thyroid function (prior to
and periodically during treatment), and hyperglycemia. For hypophysitis,
administer corticosteroids and hormone replacement as clinically
indicated. Withhold KEYTRUDA for Grade 2 and withhold or discontinue for
Grade 3 or 4 hypophysitis. Administer hormone replacement for
hypothyroidism and manage hyperthyroidism with thionamides and
beta-blockers as appropriate. Withhold or discontinue KEYTRUDA for Grade
3 or 4 hyperthyroidism. Administer insulin for type 1 diabetes, and
withhold KEYTRUDA and administer antihyperglycemics in patients with
severe hyperglycemia.
Immune-Mediated Nephritis and Renal Dysfunction
KEYTRUDA can cause immune-mediated nephritis. Nephritis occurred in 0.3%
(9/2799) of patients receiving KEYTRUDA, including Grade 2 (0.1%), 3
(0.1%), and 4 (<0.1%) nephritis. Nephritis occurred in 1.7% (7/405) of
patients receiving KEYTRUDA in combination with pemetrexed and platinum
chemotherapy. Monitor patients for changes in renal function. Administer
corticosteroids for Grade 2 or greater nephritis. Withhold KEYTRUDA for
Grade 2; permanently discontinue for Grade 3 or 4 nephritis.
Immune-Mediated Skin Reactions
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.
Other Immune-Mediated Adverse Reactions
Immune-mediated adverse reactions, which may be severe or fatal, can
occur in any organ system or tissue in patients receiving KEYTRUDA and
may also occur after discontinuation of treatment. 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, sarcoidosis, and
encephalitis. In addition, myelitis and myocarditis were reported in
other clinical trials, including cHL, and postmarketing use.
Treatment with KEYTRUDA may increase the risk of rejection in solid
organ transplant recipients. Consider the benefit of treatment vs the
risk of possible organ rejection in these patients.
Infusion-Related Reactions
KEYTRUDA can cause severe or life-threatening infusion-related
reactions, including hypersensitivity and anaphylaxis, which have been
reported in 0.2% (6/2799) of patients. Monitor patients for signs and
symptoms of infusion-related reactions. For Grade 3 or 4 reactions, stop
infusion and permanently discontinue KEYTRUDA.
Complications of Allogeneic Hematopoietic Stem Cell Transplantation
(HSCT)
Immune-mediated complications, including fatal events, occurred in
patients who underwent allogeneic HSCT after treatment with KEYTRUDA. Of
23 patients with cHL who proceeded to allogeneic HSCT after KEYTRUDA, 6
(26%) developed graft-versus-host disease (GVHD) (1 fatal case) and 2
(9%) developed severe hepatic veno-occlusive disease (VOD) after
reduced-intensity conditioning (1 fatal case). 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. Follow patients closely for early evidence of
transplant-related complications such as hyperacute graft-versus-host
disease (GVHD), Grade 3 to 4 acute GVHD, steroid-requiring febrile
syndrome, hepatic veno-occlusive disease (VOD), and other
immune-mediated adverse reactions.
In patients with a history of allogeneic HSCT, acute GVHD (including
fatal GVHD) has been reported after treatment with KEYTRUDA. Patients
who experienced GVHD after their transplant procedure may be at
increased risk for GVHD after KEYTRUDA. Consider the benefit of KEYTRUDA
vs the risk of GVHD in these patients.
Increased Mortality in Patients With Multiple Myeloma
In 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
trials.
Embryofetal Toxicity
Based on its mechanism of action, KEYTRUDA can cause fetal harm when
administered to a pregnant woman.
