By Year End, Data on KEYTRUDA in Seven Tumor
Types Will Have Been Presented
Merck (NYSE:MRK), known as MSD outside the United States and
Canada, announced today that in November and December, data will be
presented for the first time investigating the use of KEYTRUDA®
(pembrolizumab) – the company’s anti-PD-1 therapy – in advanced
melanoma in comparison to chemotherapy, and in relapsed/refractory
classical Hodgkin Lymphoma (cHL) as well as advanced triple
negative breast cancer (TNBC). These studies will be presented in
oral sessions at the Society for Melanoma Research (SMR) 2014
International Congress, Nov. 13 – 16, the 56th American Society of
Hematology (ASH) Annual Meeting, Dec. 6 – 9, and the San Antonio
Breast Cancer Symposium (SABCS), Dec. 9 – 13, respectively. By the
end of 2014, data on anti-tumor activity of KEYTRUDA as monotherapy
will have been presented in seven different tumor types.
“Our focus on evaluating KEYTRUDA as a monotherapy is enabling
Merck to rapidly advance the clinical development of our anti-PD-1
therapy,” said Dr. Roy Baynes, senior vice president, Global
Clinical Development, Merck Research Laboratories. “We look forward
to the first comparative data in advanced melanoma, and new data in
advanced triple negative breast cancer and classical Hodgkin
Lymphoma being presented. We continue to expand our immuno-oncology
clinical program with KEYTRUDA both as monotherapy and in
combination with other agents.”
KEYTRUDA is indicated in the United States at a dose of 2 mg/kg
every three weeks for the treatment of patients with unresectable
or metastatic melanoma and disease progression following ipilimumab
and, if BRAF V600 mutation positive, a BRAF inhibitor. This
indication is approved under accelerated approval based on tumor
response rate and durability of response. An improvement in
survival or disease-related symptoms has not yet been established.
Continued approval for this indication may be contingent upon
verification and description of clinical benefit in the
confirmatory trials.

About KEYTRUDA (pembrolizumab)
KEYTRUDA (pembrolizumab) is a humanized monoclonal antibody that
blocks the interaction between PD-1 and its ligands, PD-L1 and
PD-L2. By binding to the PD-1 receptor and blocking the interaction
with the receptor ligands, KEYTRUDA releases the PD-1
pathway-mediated inhibition of the immune response, including the
anti-tumor immune response.
Selected Important Safety Information for KEYTRUDA
Pneumonitis occurred in 12 (2.9%) of 411 patients with advanced
melanoma receiving KEYTRUDA (the approved indication in the United
States), including Grade 2 or 3 cases in 8 (1.9%) and 1 (0.2%)
patients, respectively. 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 pneumonitis.
Colitis (including microscopic colitis) occurred in 4 (1%) of
411 patients, including Grade 2 or 3 cases in 1 (0.2%) and 2 (0.5%)
patients respectively, receiving KEYTRUDA. 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.
Hepatitis (including autoimmune hepatitis) occurred in 2 (0.5%)
of 411 patients, including a Grade 4 case in 1 (0.2%) patient,
receiving KEYTRUDA. 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.
Hypophysitis occurred in 2 (0.5%) of 411 patients, including a
Grade 2 case in 1 and a Grade 4 case in 1 (0.2% each) patient,
receiving KEYTRUDA. Monitor for signs and symptoms of hypophysitis.
Administer corticosteroids for Grade 2 or greater hypophysitis.
Withhold KEYTRUDA for Grade 2; withhold or discontinue for Grade 3;
and permanently discontinue KEYTRUDA for Grade 4 hypophysitis.
Nephritis occurred in 3 (0.7%) patients receiving KEYTRUDA,
consisting of one case of Grade 2 autoimmune nephritis (0.2%) and
two cases of interstitial nephritis with renal failure (0.5%), one
Grade 3 and one Grade 4. 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.
Hyperthyroidism occurred in 5 (1.2%) of 411 patients, including
Grade 2 or 3 cases in 2 (0.5%) and 1 (0.2%) patients respectively,
receiving KEYTRUDA. Hypothyroidism occurred in 34 (8.3%) of 411
patients, including a Grade 3 case in 1 (0.2%) patient, receiving
KEYTRUDA. Thyroid disorders can occur at any time during treatment.
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 corticosteroids for Grade 3 or greater
hyperthyroidism. Withhold KEYTRUDA for Grade 3; permanently
discontinue KEYTRUDA for Grade 4 hyperthyroidism. Isolated
hypothyroidism may be managed with replacement therapy without
treatment interruption and without corticosteroids.
Other clinically important immune-mediated adverse reactions can
occur. The following clinically significant, immune-mediated
adverse reactions occurred in less than 1% of patients treated with
KEYTRUDA: exfoliative dermatitis, uveitis, arthritis, myositis,
pancreatitis, hemolytic anemia, partial seizures arising in a
patient with inflammatory foci in brain parenchyma, adrenal
insufficiency, myasthenic syndrome, optic neuritis, and
rhabdomyolysis.
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 of the adverse
reaction to Grade 1 or less, initiate corticosteroid taper and
continue to taper over at least 1 month. Restart KEYTRUDA if the
adverse reaction remains at Grade 1 or less. Permanently
discontinue KEYTRUDA for any severe or Grade 3 immune-mediated
adverse reaction that recurs and for any life-threatening
immune-mediated adverse reaction.
Based on its mechanism of action, KEYTRUDA may 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.
For the treatment of advanced melanoma, KEYTRUDA was
discontinued for adverse reactions in 6% of 89 patients who
received the recommended dose of 2 mg/kg and 9% of 411 patients
across all doses studied. Serious adverse reactions occurred in 36%
of patients receiving KEYTRUDA. The most frequent serious adverse
drug reactions reported in 2% or more of patients were renal
failure, dyspnea, pneumonia, and cellulitis.
The most common adverse reactions (reported in ≥20% of patients)
were fatigue (47%), cough (30%), nausea (30%), pruritus (30%), rash
(29%), decreased appetite (26%), constipation (21%), arthralgia
(20%), and diarrhea (20%).
The recommended dose of KEYTRUDA is 2 mg/kg administered as an
intravenous infusion over 30 minutes every three weeks until
disease progression or unacceptable toxicity. No formal
pharmacokinetic drug interaction studies have been conducted with
KEYTRUDA. 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. Safety and
effectiveness of KEYTRUDA have not been established in pediatric
patients.
