A Phase II Study of MK-3475 in Patients With Advanced Merkel Cell Carcinoma (MCC)

This phase II trial studies how well pembrolizumab works in treating patients with Merkel
cell cancer that cannot be removed by surgery or controlled with treatment, or has spread to
other parts of the body. Pembrolizumab may stimulate the immune system to identify and
destroy cancer cells.

PRIMARY OBJECTIVES:

I. To determine the clinical efficacy of MK-3475 (pembrolizumab) as the first systemic
intervention for patients with advanced Merkel cell carcinoma (MCC).

SECONDARY OBJECTIVES:

I. To determine the clinical activity of MK-3475 as the first systemic intervention for
patients with advanced MCC.

TERTIARY OBJECTIVES:

I. To determine the immune correlates of the clinical activity of MK-3475.

OUTLINE:

Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats
every 21 days for up to 24 months in the absence of disease progression* or unacceptable
toxicity.

* NOTE: Patients with confirmed disease progression may continue to receive treatment if they
are otherwise clinically stable until there is an increase in tumor burden of 25% or more
following initial confirmation of progression. Under exceptional circumstances, and with
protocol principal investigator (P.I.) and Cancer Immunotherapy Trials Network (CITN) P.I.
approval, patients may receive treatment beyond 2 years.

After completion of study treatment, patients are followed up at 30 days and then every 3
months for 1 year, every 6 months for 2 years, annually until the patient has completed 3
years of follow up for disease assessment, and then every 12 weeks.

control, or be surgically sterile, or abstain from heterosexual activity
beginning with the screening visit and for the duration of study participation,
through 120 days beyond last dose of MK-3475 administration; patients of

participation for the full duration of the trial, or is not in the best interest of
the patient to participate, in the opinion of the treating investigator

- Patient has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial

- Patient has uncontrolled intercurrent illness including, but not limited to, ongoing
or active infection, interstitial lung disease, non-infectious pneumonitis,

discontinued if the mother is treated with MK-3475

- Men and nonpregnant, non-breast-feeding women may be enrolled if they are willing
to use 2 methods of birth control or are considered highly unlikely to conceive;
highly unlikely to conceive is defined as (1) surgically sterilized, or (2)
postmenopausal (a woman who is >= 45 years of age and has not had menses for
greater than 1 year will be considered postmenopausal), or (3) not heterosexually
active for the duration of the study; the 2 birth control methods can be barrier

should start using birth control from the screening visit throughout the study
period up to 120 days after the last dose of study therapy

- The following are considered adequate barrier methods of contraception:
diaphragm, condom (by the partner), copper intrauterine device, sponge, or
spermicide; appropriate hormonal contraceptives will include any registered and
marketed contraceptive agent that contains an estrogen and/or a progestational
agent (including oral, subcutaneous, intrauterine, or intramuscular agents)

- Patients should be informed that taking the study medication may involve unknown
risks to the fetus (unborn baby) if pregnancy were to occur during the study; in
order to participate in the study, they must adhere to the contraception
requirement (described above) for the duration of the study and during the
follow-up period described above; if there is any question that a subject will
not reliably comply with the requirements for contraception, that subject should
not be entered into the study

- Pregnancy: if a patient inadvertently becomes pregnant while on treatment with
MK-3475, the patient will immediately be removed from the study; the site will
contact the patient at least monthly and document the patient's status until the
pregnancy has been completed or terminated; the outcome of the pregnancy will be
reported without delay and within 24 hours if the outcome is a serious adverse
experience (e.g., death, abortion, congenital anomaly, or other disabling or
life-threatening complication to the mother or newborn); the study investigator
will make every effort to obtain permission to follow the outcome of the
pregnancy and report the condition of the fetus or newborn; if a male patient
impregnates his female partner the study personnel at the site must be informed
immediately and the pregnancy reported and followed
