Updated Findings with Longer Follow-Up in
Classical Hodgkin Lymphoma to be Featured in Oral
Presentations
Merck (NYSE:MRK), known as MSD outside the United States and
Canada, today announced that new data regarding the investigational
use of KEYTRUDA® (pembrolizumab), the company’s anti-PD-1 therapy,
in patients with a range of blood cancers including classical
Hodgkin lymphoma and primary mediastinal large B-cell lymphoma,
will be presented at the 58th Annual Meeting of the American
Society of Hematology (ASH) in San Diego, Dec. 3-6.
“There is an urgent need for new treatment approaches in blood
cancers, especially for those patients who have relapsed or not
responded to current therapies,” said Dr. Roger M. Perlmutter,
president, Merck Research Laboratories. “We hope to learn that
PD-1-directed immunotherapy may be used to help patients suffering
from these difficult to treat malignancies.”
The KEYTRUDA clinical development program includes more than 30
tumor types in more than 360 clinical trials, including over 200
trials that combine KEYTRUDA with other cancer treatments. For
hematologic malignancies specifically, Merck is conducting broad
immuno-oncology research assessing the role of monotherapy and
combination regimens with KEYTRUDA. The program includes nearly 40
ongoing studies – several of which are registration-enabling trials
– across more than 20 hematologic disease subtypes, including
leukemia, lymphomas, and myeloma.
Below is a select list of KEYTRUDA data to be featured in oral
presentations (all at the San Diego Convention Center):

About KEYTRUDA® (pembrolizumab)
KEYTRUDA is a humanized monoclonal antibody that works by
increasing the ability of the body’s immune system to help detect
and fight tumor cells. KEYTRUDA 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.
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 use vial.
KEYTRUDA Indications and Dosing
Melanoma
KEYTRUDA is indicated for the treatment of patients with
unresectable or metastatic melanoma at a dose of 2 mg/kg every
three weeks until disease progression or unacceptable toxicity.
Lung Cancer
KEYTRUDA 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 (pembrolizumab) 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.
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.
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.
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 (pembrolizumab) 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.
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 (pembrolizumab) 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.
KEYTRUDA can cause severe or life-threatening infusion-related
reactions, 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.
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-002, KEYTRUDA was discontinued due to adverse
reactions in 12% of 357 patients with advanced melanoma; the most
common (≥1%) were general physical health deterioration (1%),
asthenia (1%), dyspnea (1%), pneumonitis (1%), and generalized
edema (1%). Adverse reactions leading to interruption of KEYTRUDA
occurred in 14% of patients; the most common (≥1%) were dyspnea
(1%), diarrhea (1%), and maculopapular rash (1%). The most common
adverse reactions with KEYTRUDA (pembrolizumab) vs chemotherapy
were fatigue (43% with KEYTRUDA), pruritus (28% vs 8%), rash (24%
vs 8%), constipation (22% vs 20%), nausea (22% with KEYTRUDA),
diarrhea (20% vs 20%), and decreased appetite (20% with KEYTRUDA).
Corresponding incidence rates are listed for chemotherapy only for
those adverse reactions that occurred at the same or lower rate
than with KEYTRUDA.
KEYTRUDA 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%).
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.
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.
Safety and effectiveness of KEYTRUDA have not been established
in pediatric patients.
