First Overall Survival Analysis for KEYTRUDA
Plus LENVIMA Combination in a Phase 3 Study in Advanced Endometrial
Cancer
KEYTRUDA® (pembrolizumab) Plus LENVIMA®
(lenvatinib) Combination Demonstrated Statistically Significant
Improvement in Overall Survival, Progression-Free Survival and
Objective Response Rate Versus Chemotherapy in Patients With
Advanced Endometrial Cancer Following Prior Systemic Therapy in
Phase 3 Study
Merck (NYSE: MRK), known as MSD outside the United States and
Canada, and Eisai today announced that the pivotal Phase 3
KEYNOTE-775/Study 309 trial evaluating the investigational use of
KEYTRUDA, Merck’s anti-PD-1 therapy, plus LENVIMA, the orally
available multiple receptor tyrosine kinase inhibitor discovered by
Eisai, met its dual primary endpoints of overall survival (OS) and
progression-free survival (PFS) and its secondary efficacy endpoint
of objective response rate (ORR) in patients with advanced
endometrial cancer following at least one prior platinum-based
regimen. These positive results were observed in the mismatch
repair proficient (pMMR) subgroup and the intention-to-treat (ITT)
study population, which includes both patients with endometrial
carcinoma that is pMMR as well as patients whose disease is
microsatellite instability-high (MSI-H)/mismatch repair deficient
(dMMR). Based on an analysis conducted by an independent Data
Monitoring Committee, KEYTRUDA plus LENVIMA demonstrated a
statistically significant and clinically meaningful improvement in
OS, PFS and ORR versus chemotherapy (treatment of physician’s
choice [TPC] of doxorubicin or paclitaxel). The safety profile of
the KEYTRUDA plus LENVIMA combination was consistent with
previously reported studies. Merck and Eisai will discuss these
data with regulatory authorities worldwide, with the intent to
submit marketing authorization applications based on these results,
and plan to present these results at an upcoming medical
meeting.
“Women with advanced endometrial cancer are faced with high
mortality rates and limited treatment options following initial
systemic therapy,” said Dr. Gregory Lubiniecki, Associate Vice
President, Oncology Clinical Research, Merck Research Laboratories.
“These are the first results from a Phase 3 trial of a combination
regimen including immunotherapy in advanced endometrial carcinoma
that have shown a statistically significant improvement in overall
survival, progression-free survival and objective response rate
versus chemotherapy. Merck and Eisai are dedicated to continuing to
research the KEYTRUDA plus LENVIMA combination and discover new
approaches to address unmet needs for devastating diseases such as
endometrial carcinoma.”
“We are encouraged by the data observed in KEYNOTE-775/Study
309, which represent a possible step forward for patients impacted
by advanced endometrial carcinoma and support the results seen in
the advanced endometrial cancer cohort of KEYNOTE-146/Study 111,”
said Dr. Takashi Owa, Vice President, Chief Medicine Creation
Officer and Chief Discovery Officer, Oncology Business Group at
Eisai. “As more clinical data from the LEAP (LEnvatinib And
Pembrolizumab) program are revealed, we cannot help but be
energized by the trajectory of our collaboration with Merck and the
benefits we hope to provide to patients together. Most importantly,
we are grateful for the trust that the patients and healthcare
professionals who participated in this trial have shown us.”
KEYNOTE-775/Study 309 is the confirmatory trial for
KEYNOTE-146/Study 111, which supported the U.S. Food and Drug
Administration’s (FDA) 2019 accelerated approval of the KEYTRUDA
plus LENVIMA combination for the treatment of patients with
advanced endometrial carcinoma that is not MSI-H or dMMR, who have
disease progression following prior systemic therapy and are not
candidates for curative surgery or radiation. This accelerated
approval was based on tumor response rate and durability of
response and was the first approval granted under Project Orbis, an
initiative of the FDA Oncology Center of Excellence that provides a
framework for concurrent submission and review of oncology drugs
among its international partners. Under Project Orbis, Health
Canada and Australia’s Therapeutic Goods Administration (TGA)
granted conditional and provisional approvals, respectively, for
this indication.
Merck and Eisai are studying the KEYTRUDA plus LENVIMA
combination through the LEAP (LEnvatinib And Pembrolizumab)
clinical program in 13 different tumor types across 20 clinical
trials, including a Phase 3 trial evaluating the combination in the
first-line setting for patients with advanced endometrial carcinoma
(LEAP-001).
About KEYNOTE-775/Study 309
KEYNOTE-775/Study 309 is a multicenter, randomized, open-label,
Phase 3 trial (ClinicalTrials.gov, NCT03517449) evaluating KEYTRUDA
in combination with LENVIMA in patients with advanced endometrial
cancer following at least one prior platinum-based regimen. The
dual primary endpoints are OS and PFS, as assessed by Blinded
Independent Central Review (BICR) per Response Evaluation Criteria
in Solid Tumors Version (RECIST) v1.1. Select secondary endpoints
include objective response rate (ORR) by BICR per RECIST v1.1 and
safety/tolerability. Of the 827 patients enrolled, 697 patients had
tumors that were non-MSI-H or pMMR, and 130 patients had tumors
that were MSI-H or dMMR. Patients were randomized 1:1 to
receive:
- KEYTRUDA (200 mg intravenously [IV] every three weeks) for up
to 35 cycles (approximately two years) in combination with LENVIMA
(20 mg orally once daily); or
- Chemotherapy (Treatment of physician’s choice [TPC] of either
doxorubicin 60 mg/m2 IV every three weeks for up to a maximum
cumulative dose of 500 mg/m2 or paclitaxel 80 mg/m2 IV on a 28-day
cycle [three weeks of receiving weekly paclitaxel and one week of
not receiving paclitaxel])
About Endometrial Cancer
Endometrial cancer begins in the inner lining of the uterus,
which is known as the endometrium and is the most common type of
cancer in the uterus. In 2018, it was estimated there were more
than 382,000 new cases and nearly 90,000 deaths from uterine body
cancers worldwide (these estimates include both endometrial cancers
and uterine sarcomas; more than 90% of uterine body cancers occur
in the endometrium, so the actual numbers for endometrial cancer
cases and deaths are slightly lower than these estimates). In the
U.S., it is estimated there will be almost 66,000 new cases of
uterine body cancer and nearly 13,000 deaths from the disease in
2020. The five-year survival rate for advanced or metastatic
endometrial cancer (stage IV) is estimated to be approximately
17%.
About KEYTRUDA® (pembrolizumab) Injection, 100 mg
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 1,300 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
Severe and Fatal Immune-Mediated Adverse Reactions
KEYTRUDA is a monoclonal antibody that belongs to a class of
drugs that bind to either the programmed death receptor-1 (PD-1) or
the programmed death ligand 1 (PD-L1), blocking the PD-1/PD-L1
pathway, thereby removing inhibition of the immune response,
potentially breaking peripheral tolerance and inducing
immune-mediated adverse reactions. Immune-mediated adverse
reactions, which may be severe or fatal, can occur in any organ
system or tissue, can affect more than one body system
simultaneously, and can occur at any time after starting treatment
or after discontinuation of treatment.
Monitor patients closely for symptoms and signs that may be
clinical manifestations of underlying immune-mediated adverse
reactions. Early identification and management are essential to
ensure safe use of anti–PD-1/PD-L1 treatments. Evaluate liver
enzymes, creatinine, and thyroid function at baseline and
periodically during treatment. In cases of suspected
immune-mediated adverse reactions, initiate appropriate workup to
exclude alternative etiologies, including infection. Institute
medical management promptly, including specialty consultation as
appropriate.
Withhold or permanently discontinue KEYTRUDA depending on
severity of the immune-mediated adverse reaction. In general, if
KEYTRUDA requires interruption or discontinuation, administer
systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or
equivalent) until improvement to Grade 1 or less. Upon improvement
to Grade 1 or less, initiate corticosteroid taper and continue to
taper over at least 1 month. Consider administration of other
systemic immunosuppressants in patients whose adverse reactions are
not controlled with corticosteroid therapy.
Immune-Mediated Pneumonitis
KEYTRUDA can cause immune-mediated pneumonitis. The incidence is
higher in patients who have received prior thoracic radiation.
Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients
receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3
(0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were
required in 67% (63/94) of patients. Pneumonitis led to permanent
discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9%
(26) of patients. All patients who were withheld reinitiated
KEYTRUDA after symptom improvement; of these, 23% had recurrence.
Pneumonitis resolved in 59% of the 94 patients.
Pneumonitis occurred in 8% (31/389) of adult patients with cHL
receiving KEYTRUDA as a single agent, including Grades 3-4 in 2.3%
of patients. Patients received high-dose corticosteroids for a
median duration of 10 days (range: 2 days to 53 months).
Pneumonitis rates were similar in patients with and without prior
thoracic radiation. Pneumonitis led to discontinuation of KEYTRUDA
in 5.4% (21) of patients, 42% of these patients interrupted
KEYTRUDA, 68% discontinued KEYTRUDA, and 77% had resolution.
Immune-Mediated Colitis
KEYTRUDA can cause immune-mediated colitis, which may present
with diarrhea. Cytomegalovirus infection/reactivation has been
reported in patients with corticosteroid-refractory immune-mediated
colitis. In cases of corticosteroid-refractory colitis, consider
repeating infectious workup to exclude alternative etiologies.
Immune-mediated colitis occurred in 1.7% (48/2799) of patients
receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (1.1%),
and Grade 2 (0.4%) reactions. Systemic corticosteroids were
required in 69% (33/48); additional immunosuppressant therapy was
required in 4.2% of patients. Colitis led to permanent
discontinuation of KEYTRUDA in 0.5% (15) and withholding in 0.5%
(13) of patients. All patients who were withheld reinitiated
KEYTRUDA after symptom improvement; of these, 23% had recurrence.
Colitis resolved in 85% of the 48 patients.
Hepatotoxicity and Immune-Mediated
Hepatitis
KEYTRUDA as a Single Agent
KEYTRUDA can cause immune-mediated hepatitis. Immune-mediated
hepatitis occurred in 0.7% (19/2799) of patients receiving
KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.4%), and Grade 2
(0.1%) reactions. Systemic corticosteroids were required in 68%
(13/19) of patients; additional immunosuppressant therapy was
required in 11% of patients. Hepatitis led to permanent
discontinuation of KEYTRUDA in 0.2% (6) and withholding in 0.3% (9)
of patients. All patients who were withheld reinitiated KEYTRUDA
after symptom improvement; of these, none had recurrence. Hepatitis
resolved in 79% of the 19 patients.
KEYTRUDA with Axitinib
KEYTRUDA in combination with axitinib can cause hepatic
toxicity. Monitor liver enzymes before initiation of and
periodically throughout treatment. Consider monitoring more
frequently as compared to when the drugs are administered as single
agents. For elevated liver enzymes, interrupt KEYTRUDA and
axitinib, and consider administering corticosteroids as needed.
With the combination of KEYTRUDA and axitinib, Grades 3 and 4
increased alanine aminotransferase (ALT) (20%) and increased
aspartate aminotransferase (AST) (13%) were seen, which was at a
higher frequency compared to KEYTRUDA alone. Fifty-nine percent of
the patients with increased ALT received systemic corticosteroids.
In patients with ALT ≥3 times upper limit of normal (ULN) (Grades
2-4, n=116), ALT resolved to Grades 0-1 in 94%. Among the 92
patients who were rechallenged with either KEYTRUDA (n=3) or
axitinib (n=34) administered as a single agent or with both (n=55),
recurrence of ALT ≥3 times ULN was observed in 1 patient receiving
KEYTRUDA, 16 patients receiving axitinib, and 24 patients receiving
both. All patients with a recurrence of ALT ≥3 ULN subsequently
recovered from the event.
Immune-Mediated
Endocrinopathies
Adrenal Insufficiency
KEYTRUDA can cause primary or secondary adrenal insufficiency.
For Grade 2 or higher, initiate symptomatic treatment, including
hormone replacement as clinically indicated. Withhold KEYTRUDA
depending on severity. Adrenal insufficiency occurred in 0.8%
(22/2799) of patients receiving KEYTRUDA, including Grade 4
(<0.1%), Grade 3 (0.3%), and Grade 2 (0.3%) reactions. Systemic
corticosteroids were required in 77% (17/22) of patients; of these,
the majority remained on systemic corticosteroids. Adrenal
insufficiency led to permanent discontinuation of KEYTRUDA in
<0.1% (1) and withholding in 0.3% (8) of patients. All patients
who were withheld reinitiated KEYTRUDA after symptom
improvement.
Hypophysitis
KEYTRUDA can cause immune-mediated hypophysitis. Hypophysitis
can present with acute symptoms associated with mass effect such as
headache, photophobia, or visual field defects. Hypophysitis can
cause hypopituitarism. Initiate hormone replacement as indicated.
Withhold or permanently discontinue KEYTRUDA depending on severity.
Hypophysitis occurred in 0.6% (17/2799) of patients receiving
KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.3%), and Grade 2
(0.2%) reactions. Systemic corticosteroids were required in 94%
(16/17) of patients; of these, the majority remained on systemic
corticosteroids. Hypophysitis led to permanent discontinuation of
KEYTRUDA in 0.1% (4) and withholding in 0.3% (7) of patients. All
patients who were withheld reinitiated KEYTRUDA after symptom
improvement.
Thyroid Disorders
KEYTRUDA can cause immune-mediated thyroid disorders.
Thyroiditis can present with or without endocrinopathy.
Hypothyroidism can follow hyperthyroidism. Initiate hormone
replacement for hypothyroidism or institute medical management of
hyperthyroidism as clinically indicated. Withhold or permanently
discontinue KEYTRUDA depending on severity. Thyroiditis occurred in
0.6% (16/2799) of patients receiving KEYTRUDA, including Grade 2
(0.3%). None discontinued, but KEYTRUDA was withheld in <0.1%
(1) of patients.
Hyperthyroidism occurred in 3.4% (96/2799) of patients receiving
KEYTRUDA, including Grade 3 (0.1%) and Grade 2 (0.8%). It led to
permanent discontinuation of KEYTRUDA in <0.1% (2) and
withholding in 0.3% (7) of patients. All patients who were withheld
reinitiated KEYTRUDA after symptom improvement. Hypothyroidism
occurred in 8% (237/2799) of patients receiving KEYTRUDA, including
Grade 3 (0.1%) and Grade 2 (6.2%). It led to permanent
discontinuation of KEYTRUDA in <0.1% (1) and withholding in 0.5%
(14) of patients. All patients who were withheld reinitiated
KEYTRUDA after symptom improvement. The majority of patients with
hypothyroidism required long-term thyroid hormone replacement. The
incidence of new or worsening hypothyroidism was higher in 1185
patients with HNSCC, occurring in 16% of patients receiving
KEYTRUDA as a single agent or in combination with platinum and FU,
including Grade 3 (0.3%) hypothyroidism. The incidence of new or
worsening hypothyroidism was higher in 389 adult patients with cHL
(17%) receiving KEYTRUDA as a single agent, including Grade 1
(6.2%) and Grade 2 (10.8%) hypothyroidism.
Type 1 Diabetes Mellitus (DM), Which Can Present With Diabetic
Ketoacidosis
Monitor patients for hyperglycemia or other signs and symptoms
of diabetes. Initiate treatment with insulin as clinically
indicated. Withhold KEYTRUDA depending on severity. Type 1 DM
occurred in 0.2% (6/2799) of patients receiving KEYTRUDA. It led to
permanent discontinuation in <0.1% (1) and withholding of
KEYTRUDA in <0.1% (1). All patients who were withheld
reinitiated KEYTRUDA after symptom improvement.
Immune-Mediated Nephritis With Renal
Dysfunction
KEYTRUDA can cause immune-mediated nephritis. Immune-mediated
nephritis occurred in 0.3% (9/2799) of patients receiving KEYTRUDA,
including Grade 4 (<0.1%), Grade 3 (0.1%), and Grade 2 (0.1%)
reactions. Systemic corticosteroids were required in 89% (8/9) of
patients. Nephritis led to permanent discontinuation of KEYTRUDA in
0.1% (3) and withholding in 0.1% (3) of patients. All patients who
were withheld reinitiated KEYTRUDA after symptom improvement; of
these, none had recurrence. Nephritis resolved in 56% of the 9
patients.
Immune-Mediated Dermatologic Adverse
Reactions
KEYTRUDA can cause immune-mediated rash or dermatitis.
Exfoliative dermatitis, including Stevens-Johnson syndrome, drug
rash with eosinophilia and systemic symptoms, and toxic epidermal
necrolysis, has occurred with anti–PD-1/PD-L1 treatments. Topical
emollients and/or topical corticosteroids may be adequate to treat
mild to moderate nonexfoliative rashes. Withhold or permanently
discontinue KEYTRUDA depending on severity. Immune-mediated
dermatologic adverse reactions occurred in 1.4% (38/2799) of
patients receiving KEYTRUDA, including Grade 3 (1%) and Grade 2
(0.1%) reactions. Systemic corticosteroids were required in 40%
(15/38) of patients. These reactions led to permanent
discontinuation in 0.1% (2) and withholding of KEYTRUDA in 0.6%
(16) of patients. All patients who were withheld reinitiated
KEYTRUDA after symptom improvement; of these, 6% had recurrence.
The reactions resolved in 79% of the 38 patients.
Other Immune-Mediated Adverse
Reactions
The following clinically significant immune-mediated adverse
reactions occurred at an incidence of <1% (unless otherwise
noted) in patients who received KEYTRUDA or were reported with the
use of other anti–PD-1/PD-L1 treatments. Severe or fatal cases have
been reported for some of these adverse reactions.
Cardiac/Vascular: Myocarditis, pericarditis, vasculitis; Nervous
System: Meningitis, encephalitis, myelitis and demyelination,
myasthenic syndrome/myasthenia gravis (including exacerbation),
Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy;
Ocular: Uveitis, iritis and other ocular inflammatory toxicities
can occur. Some cases can be associated with retinal detachment.
Various grades of visual impairment, including blindness, can
occur. If uveitis occurs in combination with other immune-mediated
adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome,
as this may require treatment with systemic steroids to reduce the
risk of permanent vision loss; Gastrointestinal: Pancreatitis, to
include increases in serum amylase and lipase levels, gastritis,
duodenitis; Musculoskeletal and Connective Tissue:
Myositis/polymyositis, rhabdomyolysis (and associated sequelae,
including renal failure), arthritis (1.5%), polymyalgia rheumatica;
Endocrine: Hypoparathyroidism; Hematologic/Immune: Hemolytic
anemia, aplastic anemia, hemophagocytic lymphohistiocytosis,
systemic inflammatory response syndrome, histiocytic necrotizing
lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune
thrombocytopenic purpura, solid organ transplant rejection.
Infusion-Related Reactions
KEYTRUDA can cause severe or life-threatening infusion-related
reactions, including hypersensitivity and anaphylaxis, which have
been reported in 0.2% of 2799 patients receiving KEYTRUDA. Monitor
for signs and symptoms of infusion-related reactions. Interrupt or
slow the rate of infusion for Grade 1 or Grade 2 reactions. For
Grade 3 or Grade 4 reactions, stop infusion and permanently
discontinue KEYTRUDA.
Complications of Allogeneic Hematopoietic Stem Cell
Transplantation (HSCT)
Fatal and other serious complications can occur in patients who
receive allogeneic HSCT before or after anti–PD-1/PD-L1 treatment.
Transplant-related complications include hyperacute
graft-versus-host disease (GVHD), acute and chronic GVHD, hepatic
veno-occlusive disease after reduced intensity conditioning, and
steroid-requiring febrile syndrome (without an identified
infectious cause). These complications may occur despite
intervening therapy between anti–PD-1/PD-L1 treatment and
allogeneic HSCT. Follow patients closely for evidence of these
complications and intervene promptly. Consider the benefit vs risks
of using anti–PD-1/PD-L1 treatments prior to or after an allogeneic
HSCT.
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 an
anti–PD-1/PD-L1 treatment 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. Advise women of this
potential risk. In females of reproductive potential, verify
pregnancy status prior to initiating KEYTRUDA and advise them to
use effective contraception during treatment and for 4 months after
the last dose.
Adverse Reactions
In KEYNOTE-006, KEYTRUDA was discontinued due to adverse
reactions in 9% of 555 patients with advanced melanoma; adverse

About LENVIMA® (lenvatinib) Capsules
LENVIMA® (lenvatinib) is a kinase inhibitor that is
indicated:
- For the treatment of patients with locally recurrent or
metastatic, progressive, radioactive iodine-refractory
differentiated thyroid cancer (RAI-refractory DTC)
- In combination with everolimus, for the treatment of patients
with advanced renal cell carcinoma (RCC) following one prior
anti-angiogenic therapy
- For the first-line treatment of patients with unresectable
hepatocellular carcinoma (HCC)
- In combination with KEYTRUDA, for the treatment of patients
with advanced endometrial carcinoma that is not microsatellite
instability-high (MSI-H) or mismatch repair deficient (dMMR), who
have disease progression following prior systemic therapy, and are
not candidates for curative surgery or radiation. 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 trial
LENVIMA, discovered and developed by Eisai, is a kinase
inhibitor that inhibits the kinase activities of vascular
endothelial growth factor (VEGF) receptors VEGFR1 (FLT1), VEGFR2
(KDR), and VEGFR3 (FLT4). LENVIMA inhibits other kinases 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. In syngeneic mouse tumor models, lenvatinib decreased
tumor-associated macrophages, increased activated cytotoxic T
cells, and demonstrated greater antitumor activity in combination
with an anti-PD-1 monoclonal antibody compared to either treatment
alone.
Selected Safety Information
Warnings and Precautions
Hypertension. In DTC, hypertension occurred in 73% of
patients on LENVIMA (44% grade 3-4). In RCC, hypertension occurred
in 42% of patients on LENVIMA + everolimus (13% grade 3). Systolic
blood pressure ≥160 mmHg occurred in 29% of patients, and 21% had
diastolic blood pressure ≥100 mmHg. In HCC, hypertension occurred
in 45% of LENVIMA-treated patients (24% grade 3). Grade 4
hypertension was not reported in HCC.
Serious complications of poorly controlled hypertension have
been reported. Control blood pressure prior to initiation. Monitor
blood pressure after 1 week, then every 2 weeks for the first 2
months, and then at least monthly thereafter during treatment.
Withhold and resume at reduced dose when hypertension is controlled
or permanently discontinue based on severity.
Cardiac Dysfunction. Serious and fatal cardiac
dysfunction can occur with LENVIMA. Across clinical trials in 799
patients with DTC, RCC, and HCC, grade 3 or higher cardiac
dysfunction occurred in 3% of LENVIMA treated patients. Monitor for
clinical symptoms or signs of cardiac dysfunction. Withhold and
resume at reduced dose upon recovery or permanently discontinue
based on severity.
Arterial Thromboembolic Events. Among patients receiving
LENVIMA or LENVIMA + everolimus, arterial thromboembolic events of
any severity occurred in 2% of patients in RCC and HCC and 5% in
DTC. Grade 3-5 arterial thromboembolic events ranged from 2% to 3%
across all clinical trials. Permanently discontinue following an
arterial thrombotic event. The safety of resuming after an arterial
thromboembolic event has not been established and LENVIMA has not
been studied in patients who have had an arterial thromboembolic
event within the previous 6 months.
Hepatotoxicity. Across clinical studies enrolling 1,327
LENVIMA-treated patients with malignancies other than HCC, serious
hepatic adverse reactions occurred in 1.4% of patients. Fatal
events, including hepatic failure, acute hepatitis and hepatorenal
syndrome, occurred in 0.5% of patients. In HCC, hepatic
encephalopathy occurred in 8% of LENVIMA-treated patients (5% grade
3-5). Grade 3-5 hepatic failure occurred in 3% of LENVIMA-treated
patients. 2% of patients discontinued LENVIMA due to hepatic
encephalopathy and 1% discontinued due to hepatic failure.
Monitor liver function prior to initiation, then every 2 weeks
for the first 2 months, and at least monthly thereafter during
treatment. Monitor patients with HCC closely for signs of hepatic
failure, including hepatic encephalopathy. Withhold and resume at
reduced dose upon recovery or permanently discontinue based on
severity.
Renal Failure or Impairment. Serious including fatal
renal failure or impairment can occur with LENVIMA. Renal
impairment was reported in 14% and 7% of LENVIMA-treated patients
in DTC and HCC, respectively. Grade 3-5 renal failure or impairment
occurred in 3% of patients with DTC and 2% of patients with HCC,
including 1 fatal event in each study. In RCC, renal impairment or
renal failure was reported in 18% of LENVIMA + everolimus–treated
patients (10% grade 3).
Initiate prompt management of diarrhea or
dehydration/hypovolemia. Withhold and resume at reduced dose upon
recovery or permanently discontinue for renal failure or impairment
based on severity.
Proteinuria. In DTC and HCC, proteinuria was reported in
34% and 26% of LENVIMA-treated patients, respectively. Grade 3
proteinuria occurred in 11% and 6% in DTC and HCC, respectively. In
RCC, proteinuria occurred in 31% of patients receiving LENVIMA +
everolimus (8% grade 3). Monitor for proteinuria prior to
initiation and periodically during treatment. If urine dipstick
proteinuria ≥2+ is detected, obtain a 24-hour urine protein.
Withhold and resume at reduced dose upon recovery or permanently
discontinue based on severity.
Diarrhea. Of the 737 LENVIMA-treated patients in DTC and
HCC, diarrhea occurred in 49% (6% grade 3). In RCC, diarrhea
occurred in 81% of LENVIMA + everolimus–treated patients (19% grade
3). Diarrhea was the most frequent cause of dose
interruption/reduction, and diarrhea recurred despite dose
reduction. Promptly initiate management of diarrhea. Withhold and
resume at reduced dose upon recovery or permanently discontinue
based on severity.
Fistula Formation and Gastrointestinal Perforation. Of
the 799 patients treated with LENVIMA or LENVIMA + everolimus in
DTC, RCC, and HCC, fistula or gastrointestinal perforation occurred
in 2%. Permanently discontinue in patients who develop
gastrointestinal perforation of any severity or grade 3-4
fistula.
QT Interval Prolongation. In DTC, QT/QTc interval
prolongation occurred in 9% of LENVIMA-treated patients and QT
interval prolongation of >500 ms occurred in 2%. In RCC, QTc
interval increases of >60 ms occurred in 11% of patients
receiving LENVIMA + everolimus and QTc interval >500 ms occurred
in 6%. In HCC, QTc interval increases of >60 ms occurred in 8%
of LENVIMA-treated patients and QTc interval >500 ms occurred in
2%.
Monitor and correct electrolyte abnormalities at baseline and
periodically during treatment. Monitor electrocardiograms in
patients with congenital long QT syndrome, congestive heart
failure, bradyarrhythmias, or those who are taking drugs known to
prolong the QT interval, including Class Ia and III
antiarrhythmics. Withhold and resume at reduced dose upon recovery
based on severity.
Hypocalcemia. In DTC, grade 3-4 hypocalcemia occurred in
9% of LENVIMA-treated patients. In 65% of cases, hypocalcemia
improved or resolved following calcium supplementation with or
without dose interruption or dose reduction. In RCC, grade 3-4
hypocalcemia occurred in 6% of LENVIMA + everolimus– treated
patients. In HCC, grade 3 hypocalcemia occurred in 0.8% of
LENVIMA-treated patients. Monitor blood calcium levels at least
monthly and replace calcium as necessary during treatment. Withhold
and resume at reduced dose upon recovery or permanently discontinue
depending on severity.
Reversible Posterior Leukoencephalopathy Syndrome. Across
clinical studies of 1,823 patients who received LENVIMA as a single
agent, RPLS occurred in 0.3%. Confirm diagnosis of RPLS with MRI.
Withhold and resume at reduced dose upon recovery or permanently
discontinue depending on severity and persistence of neurologic
symptoms.
Hemorrhagic Events. Serious including fatal hemorrhagic
events can occur with LENVIMA. In DTC, RCC, and HCC clinical
trials, hemorrhagic events, of any grade, occurred in 29% of the
799 patients treated with LENVIMA as a single agent or in
combination with everolimus. The most frequently reported
hemorrhagic events (all grades and occurring in at least 5% of
patients) were epistaxis and hematuria. In DTC, grade 3-5
hemorrhage occurred in 2% of LENVIMA-treated patients, including 1
fatal intracranial hemorrhage among 16 patients who received
LENVIMA and had CNS metastases at baseline. In RCC, grade 3-5
hemorrhage occurred in 8% of LENVIMA + everolimus–treated patients,
including 1 fatal cerebral hemorrhage. In HCC, grade 3-5 hemorrhage
occurred in 5% of LENVIMA-treated patients, including 7 fatal
hemorrhagic events. Serious tumor-related bleeds, including fatal
hemorrhagic events, occurred in LENVIMA-treated patients in
clinical trials and in the postmarketing setting. In postmarketing
surveillance, serious and fatal carotid artery hemorrhages were
seen more frequently in patients with anaplastic thyroid carcinoma
(ATC) than other tumors. Safety and effectiveness of LENVIMA in
patients with ATC have not been demonstrated in clinical
trials.
Consider the risk of severe or fatal hemorrhage associated with
tumor invasion or infiltration of major blood vessels (e.g.,
carotid artery). Withhold and resume at reduced dose upon recovery
or permanently discontinue based on severity.
Impairment of Thyroid Stimulating Hormone Suppression/Thyroid
Dysfunction. LENVIMA impairs exogenous thyroid suppression. In
DTC, 88% of patients had baseline thyroid stimulating hormone (TSH)
level ≤0.5 mU/L. In patients with normal TSH at baseline, elevation
of TSH level >0.5 mU/L was observed post baseline in 57% of
LENVIMA-treated patients. In RCC and HCC, grade 1 or 2
hypothyroidism occurred in 24% of LENVIMA + everolimus–treated
patients and 21% of LENVIMA-treated patients, respectively. In
patients with normal or low TSH at baseline, elevation of TSH was
observed post baseline in 70% of LENVIMA-treated patients in HCC
and 60% of LENVIMA + everolimus–treated patients in RCC.
Monitor thyroid function prior to initiation and at least
monthly during treatment. Treat hypothyroidism according to
standard medical practice.
Impaired Wound Healing. Impaired wound healing has been
reported in patients who received LENVIMA. Withhold LENVIMA for at
least 1 week prior to elective surgery. Do not administer for at
least 2 weeks following major surgery and until adequate wound
healing. The safety of resumption of LENVIMA after resolution of
wound healing complications has not been established.
Embryo-fetal Toxicity. Based on its mechanism of action
and data from animal reproduction studies, LENVIMA can cause fetal
harm when administered to pregnant women. In animal reproduction
studies, oral administration of lenvatinib during organogenesis at
doses below the recommended clinical doses resulted in
embryotoxicity, fetotoxicity, and teratogenicity in rats and
rabbits. Advise pregnant women of the potential risk to a fetus;
and advise females of reproductive potential to use effective
contraception during treatment with LENVIMA and for at least 30
days after the last dose.

breastfed infants, advise women to discontinue breastfeeding during
treatment and for at least 1 week after last dose. LENVIMA may
impair fertility in males and females of reproductive
potential.
No dose adjustment is recommended for patients with mild (CLcr
60-89 mL/min) or moderate (CLcr 30-59 mL/min) renal impairment.
LENVIMA concentrations may increase in patients with DTC, RCC or EC
and severe (CLcr 15-29 mL/min) renal impairment. Reduce the dose
for patients with DTC, RCC, or EC and severe renal impairment.
There is no recommended dose for patients with HCC and severe renal
impairment. LENVIMA has not been studied in patients with end stage
renal disease. No dose adjustment is recommended for patients with
HCC and mild hepatic impairment (Child-Pugh A). There is no
recommended dose for patients with HCC with moderate (Child-Pugh B)
or severe (Child-Pugh C) hepatic impairment.
No dose adjustment is recommended for patients with DTC, RCC, or
EC and mild or moderate hepatic impairment. LENVIMA concentrations
may increase in patients with DTC, RCC, or EC and severe hepatic
impairment. Reduce the dose for patients with DTC, RCC, or EC and

About the Merck and Eisai Strategic Collaboration
In March 2018, Eisai and Merck, known as MSD outside the United
States and Canada, through an affiliate, entered into a strategic
collaboration for the worldwide co-development and
co-commercialization of LENVIMA. Under the agreement, the companies
will jointly develop, manufacture and commercialize LENVIMA, both
as monotherapy and in combination with Merck’s anti-PD-1 therapy
KEYTRUDA.
In addition to ongoing clinical studies evaluating the KEYTRUDA
plus LENVIMA combination across several different tumor types, the
companies have jointly initiated new clinical studies through the
LEAP (LEnvatinib And Pembrolizumab) clinical program and are
evaluating the combination in 13 different tumor types (endometrial
carcinoma, hepatocellular carcinoma, melanoma, non-small cell lung
cancer, renal cell carcinoma, squamous cell carcinoma of the head
and neck, urothelial cancer, biliary tract cancer, colorectal
cancer, gastric cancer, glioblastoma, ovarian cancer and
triple-negative breast cancer) across 20 clinical trials.
