The incidence of cutaneous squamous cell carcinoma (CSCC) is increasing, and the estimated annual 
number of deaths due to CSCC is thought to be under reported.1 The major risk factor for development 
of CSCC is exposure to UV radiation, particularly for fair-skinned people in geographic locations with 
high levels of UV radiaton.2,3 In addition, chronic immunosuppression, advanced age, exposure to 
ionizing radiation, manufacturing chemicals, arsenic, chronic ulcers, and burn scars are also risk 
factors to develop CSCC.1,4 The majority of primary CSCC is treated surgically with or without post-
operative radiation therapy depending on the risk of recurrence, and more than 95% of the patients 
are cured.1,4,5  
 
Although it is a highly curable cancer, some patients present with metastasis or locally advanced 
CSCC that are no longer amenable to surgery or radiation therapy. Unfortunately these patients are 
no longer curable, and their only optieon is palliative therapy. Among these incurable patients, 
immunocompromised patients have even worse clinical outcomes. For example, the 2-year 
progression free survival of immunocompromised patients excluding solid organ transplantation is only 
27% in a retrospective study.6 In patients with no lymph node involvement but immunocompromised 
due to chronic lymphocytic leukemia, the locoregional failure rate is 36% even when they are treated 
aggressively with radiation postoperatively.7,8 Therefore, this patient population with an extremely poor 
prognosis needs improved treatment.   
 
While immunocompromised patients have the most need for novel treatment options, they are often 
excluded in clinical trials. Recently, the programmed cell death-1 (PD-1)/programmed cell death-ligand 
1 (PD-L1) axis was determined to play an important role as immune checkpoint. PD-1 is one of the 
clinically significant checkpoint molecules that has been shown to suppress T-cell function upon 
binding to its ligands, PD-L1 and PD-L2, which are expressed on tumor cells in both preclinical models 
and clinical settings of cancer patients undergoing immunotherapy.9,10 In addition to promising efficacy, 
PD-1 and PD-L1 inhibitors are overall safe and well tolerated in a subset of immunocompromised 
patients such as patients with HIV infection, and additional studies are currently ongoing.11,12 
Immunotherapy targeting PD-1 has become a promising therapeutic option in management of CSCC.4 
Cemiplimab-rwlc is one of the PD-1 inhibitors with the most efficacy and safety data in management 
of unresectable locally advanced or metastatic CSCC.4 With Cemiplimab-rwlc as a monotherapy in 
patients with metastatic CSCC, overall complete response rate is 7% and partial response rate is 41%. 
It also has a very favorable toxicity profile. Based on these efficacy and safety data, Cemiplimab-rwlc 
is now FDA approved for the treatment of patients with metastatic CSCC or locally advanced CSCC 
who are not amenable to curative surgery or curative radiation.13 However, immunocompromised 
patients were excluded in the Cemiplimab-rwlc trial, and the safety and efficacy of Cemiplimab-rwlc is 
unknown in this patient population with the most limited treatment options. 
 
Even though it is counter intuitive to use immunotherapeutic approaches to immunocompromised 
patients, the full mechanism of how PD-1 inhibitors exerts anti-tumor effects are still unknown. In 
addition, recent data suggest that tumors with high tumor mutation burden respond better to PD-1 
inhibitors because of increased presence of neoantigens.14,15 Chung, et al. evaluated 1,300 mucosal 
head and neck SCC, 2,386 lung SCC, and 289 CSCC for tumor mutation burden and found CSCC 
has the highest number of mutations per megabase among the squamous cell carcinomas from 
various organ sites.16 Therefore, it is important to evaluate the efficacy and toxicity of Cemiplimab-rwlc 
in immunocompromised CSCC patients.

INTRODUCTION: BACKGROUND INFORMATION AND 
SCIENTIFIC RATIONALE 
2.1 
BACKGROUND INFORMATION 


Cemiplimab-rwlc in immunocompromised CSCC 
MCC 20114 
 
12 
 
Version 4.0 
29 Oct 2020 
 
 
 
It suggests that CSCC is expected to be extremely sensitive to PD-1 inhibiting agents. However, there 
is no efficacy data in any immunocompromised population due to exclusion of these patients in clinical 
trials using PD-1 inhibitors. This population specific data are required to fulfill the unmet need. 
 
 
 
 
 
Cemiplimab-rwlc has not been tested in pregnant women, and there is no information available on 
patients receiving Cemiplimab-rwlc while pregnant. There is the possibility of unforeseeable risk to 
both the pregnant woman and unborn child if exposed to Cemiplimab-rwlc during pregnancy.  
The most common side effects related to Cemiplimab-rwlc treatment are as follows: 
Possible side effects: 
Very Common (10% or more of patients):  
o Fatigue  
o Rash 
o Nausea 
Common (1 to ≤10% of patients):  
o Arthraligia (joint pain) 
o Diarrhea  
o Decreased appetite 
o Asthenia (weakness or lack of energy) 
o Myalgia 
o Vomiting 
o Itching 
o Underactive or overactive thyroid gland (which can cause tiredness, constipation, hair 
loss, sensitivity to heat or cold temperatures, mood changes, sweating, muscle aches, a 
fast heartbeat or weight changes) 
o Damage to the liver (from inflammation) that does not cause symptoms, but does cause 
an abnormal result on a blood test of liver function 
o Fever 
o Anemia (low red blood cells that can cause tiredness, physical weakness or lack of 
energy) 
o Dry mouth 
o Headache 
o Flu-like illness 
o Swelling of an arm or leg 
o Constipation 
o Cough 
o Shortness of breath 
o Insomnia (trouble sleeping) 
o Pneumonitis (inflammation of the lung) which may be life-threatening or may lead to 
death

Version 4.0 
29 Oct 2020 
 
o Abdominal pain 
o Low white blood cells (that can make it more likely to get an infection)  
o Chills 
o Dry Skin 
o Stomatitis (inflammation of mouth and lips) 
o Decreased weight  
o Dehydration 
o Infusion reactions  
o Muscle spasms 
o Back pain 
o Dizziness 
o Low phosphate in the blood (that does not cause symptoms but causes an abnormal 
blood test) 
o Blurry vision 
Uncommon (≤ 1% of patients) but serious:  
o Encephalomyelitis (inflammation of the brain), which may result in severe memory loss 
and occasionally death.  
o Myasthenia gravis, a disease that causes muscle weakness  
o Colitis, an inflammation of the colon  
o Bronchospasm, a narrowing of air passages in the lungs causing shortness of breath 
o Diabetic ketoacidosis, a severe complication of diabetes (high blood sugar) where the 
body makes too much acid in the blood. 
As of January 2017, in all patients treated in all studies with Cemiplimab-rwlc, there were 5 deaths    
associated with Cemiplimab-rwlc. One patient died from encephalomyelitis (inflammation of the 
brain), one patient died from an unknown cause, two patients died from liver failure (including one 
with liver cancer), and one patient died from Toxic Epidermal Necrolysis (a type of severe skin 
reaction).   
There are additional potential immune-related side effects from Cemiplimab-rwlc that may be serious 
and require corticosteroid treatment and interruption or discontinuation of treatment. While some of 
these side effects have been seen in patients treated with Cemiplimab-rwlc (also listed above), these 
side effects have been observed with other drugs that act on the immune system in a similar way.  It 
is important to contact your doctor immediately if you experience any of these symptoms:  
o Pneumonitis (inflammation of the lung): new or worsening cough, chest pain, or 
shortness of breath. 
o Colitis (inflammation of the colon): diarrhea, blood in stool or severe abdominal 
pain  
o Hepatitis (inflammation of the liver):  jaundice (yellowing of skin, mucus 
membranes or whites of eyes), severe nausea or vomiting, or easy bruising or 
bleeding  
o Hypophysitis (inflammation of pituitary gland which secretes hormones to control 
several body processes): persistent or unusual headache, extreme weakness, 
dizziness or fainting, vision changes, or other changes due to an effect on your 
hormones

muscle aches, intolerance to heat or cold 
o Uveitis (inflammation of the eye):   eye  redness, eye pain, light sensitivity, blurred 
vision, floaters, decreased vision  
o Skin changes: peeling of the skin over large areas of the body, rash, itching, skin 
blistering. 
o Mucositis (painful inflammation and ulceration of mucous membranes lining the 
digestive tract): painful sores in the mouth, tongue, nose or throat which can make 
it hard to eat or drink 
o Encephalitis (inflammation of the brain): headache, fever, tiredness, confusion, 
memory problems, sleepiness, seeing or hearing things that are not really there, 
seizures, stiff neck 
ALLERGIC REACTION RISK: 
There is a chance of an allergic reaction to the study drug. Low levels of doxycycline, an 
antibiotic, are used early in the manufacturing process of Cemiplimab-rwlc. The possibility 
exists of an allergic reaction in patients allergic to doxycycline.  
 
 
 
 
Cemiplimab-rwlc is one of the PD-1 inhibitors with the most efficacy and safety data in management 
of unresectable locally advanced or metastatic cutaneous SCC.4 With Cemiplimab-rwlc as a 
monotherapy in patients with metastatic CSCC, overall complete response rate is 7% and partial 
response rate is 41%. Based on these efficacy and safety data, Cemiplimab-rwlc is now FDA approved 
for the treatment of patients with metastatic CSCC or locally advanced CSCC who are not amenable 
to curative surgery or curative radiation.13 However, there is no efficacy data in any 
immunocompromised population due to exclusion of these patients in clinical trials using PD-1 
inhibitors. This population specific data are required to fulfill the unmet need. 
 
 
 
 
Primary Objective: Determine the overall response rate of Cemiplimab-rwlc in immunocompromised 
patients with unresectable locally recurrent and/or metastatic CSCC. 
 
Secondary Objective:  
1. Evaluate progression-free survival 
2. Evaluate overall survival 
3. Evaluate acute and late toxicities 
 
Exploratory Objective: 
1. Identify potential biomarkers related to response to Cemiplimab-rwlc in immunocompromised 
patients with unresectable locally recurrent and/or metastatic CSCC.

This is a single arm phase II study to evaluate the efficacy of Cemiplimab-rwlc in immunocompromised 
patients with unresectable locally recurrent or metastatic CSCC.  
 
Eligible patients will be given Cemiplimab-rwlc 350 mg IV every 3 weeks. This will be administered 
until patients get severe side effects, disease progression, or for a period of 1 year (whichever point is 
reached first). 
 
A scan will be performed approximately every 9 weeks till the time that the patient is receiving the 
treatment. We plan to recruit 27 patients.

Version 4.0 
29 Oct 2020 
 
Administration: 
• 
Administer by intravenous infusion over 30 minutes through an intravenous line containing 
a sterile, in-line or add-on 0.2 micron to 5-micron filter. 
 
 
 
Cemiplimab-rwlc  will be administrated intravenously.  
 
 
 
 
Cemiplimab-rwlc is administered as a flat dose of 350 mg IV over approximately 30 minutes every 
21 days (+/- 3 days).  
 
 
 
Patients will remain on the dosage of Cemiplimab-rwlc throughout the course of study treatment.  
Dose reduction is not allowed. The dose will be held until the resolution of the adverse events as 
below.   
 
Adverse events (AEs) are to be reported according to the National Cancer Institute Common 
Terminology Criteria for Adverse Events (NCI-CTCAE) version 5. Patients who experience grade ≥3 
treatment-related toxicity (excluding laboratory abnormalities that are considered clinically 
insignificant) that is not otherwise specified in the protocol will be required to temporarily discontinue 
treatment with Cemiplimab-rwlc. Such patients may be considered for resumption of treatment once 
the toxicity resolves to grade 1 or baseline, or when the toxicity is stable and manageable through 
supportive/medical therapy (eg, grade 3 hypertension that can be controlled with addition of a second 
anti-hypertensive agent) per the CTCAE version 5. 
 
Holding of treatment due to an AE or a missed visit if a patient is hospitalized is not a violation. If a 
patient is able to come in for a study visit according to the visit schedule, but does not receive 
Cemiplimab-rwlc, the visit should be entered into the database. The protocol assessments required 
at the visit (ie, labs, physical exam) should still be completed as far as possible and the data entered 
at the appropriate visit in the electronic case report form (CRF). If the patient is not able to come in 
for a study visit, according to the study schedule, the visit should be skipped. If a scan was missed 
as part of the skipped visit, the response assessment will be performed prior to resuming treatment 
and subsequent scans will be performed in line with the original schedule. 
 
Upon occurrence of a study treatment-related event at any time on the study, resumption of treatment 
after resolution or stabilization of the condition is allowed at the discretion of the investigator if 
resuming treatment is thought to be in the best interest of the patient, with the exception of the 
following categories: 
 
• 
Patients with events that require Cemiplimab-rwlc to be discontinued for more than 84 days 
from last scheduled dose. 
• 
Patients with grade ≥2 uveitis. Patients with grade 2 uveitis will generally be discontinued from 
study treatment, unless there is resolution to grade ≤1 AND discussion with and approval by 
the site principal investigators. All patients with grade ≥3 uveitis will be permanently 
discontinued from study treatment. 
 
After other AEs, resumption of treatment may be at the initial dose level. A patient who does not

In all study participants, submission of archived diagnostic formalin fixed paraffin embedded (FFPE) 
tumors obtained at any time prior to Cemiplimab-rwlc treatment is required. Additionally, tumor tissue 
will be obtained from the most accessible locations for a biopsy prior to initiation and at the end of 
Cemiplimab-rwlc therapy. These biopsies for only research purposes are OPTIONAL. Any metastatic 
cancer tissue obtained during the study (including but not limited to excisional, core biopsies, surgical 
specimens, etc.) will be subject to additional molecular studies in the future. 
 
PROPOSED BIOMARKER EVALUATIONS  
 
7.2.2.1 
Determination of the genomic landscape to determine tumor mutation burden 
The archived FFPE primary tumors (and subsequent metastatic tumors if available) will be analyzed 
by whole exome sequencing, and the comprehensive genomic landscape and tumor mutation burden 
will be assessed.    
 
7.2.2.2 
Evaluation of the Tumor Immune Microenvironment 
Intact immune system is critical for tumor surveillance. Comprehensive evaluation of tumor immune 
microenvironment has not been fully characterized. An innovative methodology, multiplex immune-
histochemical (mIHC) staining, allows the analysis of an array of markers from limited sample 
specimens. The evaluation of a complex cellular microenvironment is best accomplished using mIHC 
which enables simultaneous detection and measurement of multiple protein antigens on the same 
tissue section allowing accurate classification of cells as well as enumeration and quantification of

protein signal. This is accomplished by using sequential steps of primary antibody application, 
scanning the image, and then antibody stripping. The process is repeated using each antibody target. 
The result is that up to 20 protein targets can be visualized. This complex staining can then be analyzed 
by imaging systems such as the Aperio scanning system. Image analysis software can then be applied 
to enumerate cells and quantify signal. Complex analysis can determine cellular densities and also 
measure co-localized targets. The multiplexing will encompass evaluation of antigen presenting cells, 
T cells, B cells, macrophages, and tumor cells. The goal is to link a comprehensive clinical 
characterization and immune microenvironment assessment and to correlate these with Cemiplimab-
rwlc treatment response and survival.  
 
7.2.2.3 
Detection of Circulating Tumor DNA in Plasma and Its Association With Cemiplimab-
rwlc response  
Determination of early response to Cemiplimab-rwlc by conventional imaging studies can be difficult. 
Circulating tumor DNA in pre- and post-treatment plasma has been shown to track with the disease 
burden.17 We will determine the presence of a unique genomic alteration found in each patient based 
on the whole exome sequencing of their tumor and identify the presence of the alterations in circulating 
tumor DNA. Quantity of circulating tumor DNA in the plasma compared with at pre-treatment and at 
end of treatment will be correlated with the response determined by the imaging studies.       
 
 
Tissue specimens will be handled and stored according to the Laboratory Manual. 
 
Tissue/Specimen Submission  
Tumor tissue samples will be collected at pre- and post-treatment. The tumor tissue samples will be 
submitted to the Moffitt Tissue Core for banking and translational research.  
 
Pre-treatment formalin-fixed paraffin-embedded (FFPE) archived tumor samples (MANDATORY) 
 
Any archived tumor tissue (except FNA cell blocks) obtained before Cemiplimab-rwlc is allowed. An 
FFPE tumor block should be submitted with the submission form. A Pathology Report and one 
hematoxylin and eosin-stained slide documenting that the submitted block or unstained slides contain 
tumor should also be submitted with the tissue. The report and hematoxylin and eosin-stained slide 
must include the protocol number and patient’s case number. The patient’s name and/or other 
identifying information should be removed from the report. The surgical pathology numbers and 
information must NOT be removed from the report.  
 
Pre- and post-treatment tumor biopsy (Day -21 to 0 before Cemiplimab-rwlc and at the End of 
Treatment visit; OPTIONAL) 
 
The pre- and post-treatment tumor biopsy can be obtained from the primary site, lymph node 
metastasis, or other safely accessible site metastases as a punch biopsy or a core needle biopsy: one 
punch or core in formalin and the second punch or core in liquid nitrogen (or dry ice/ethanol slurry). 
The biopsy sample should be prepared: 1) as a formalin-fixed paraffin-embedded tumor block and 2) 
as a flash frozen sample in liquid nitrogen (or dry ice/ethanol slurry). The frozen specimens can be 
stored at -80°C (-70°C to -90°C).  
 
CORRELATIVE WITH BLOOD 
Blood samples must be submitted with the submission form documenting the date of collection of the 
sample; the protocol number, the patient’s case number, time point of study, and method of storage 
(for example, stored at -80°C). The frozen specimens can be stored at -80°C (-70°C to -90°C).

The blood samples should be processed as detailed in the Laboratory Manual.  
 
In brief, 
 
1 x 10 ml Lavender EDTA tube and 1 x 8.5 ml LBgard tube of blood will be generated from each 
clinical event. The samples will be processed and shipped according to the Laboratory Manual. 
 
Clinical events: 
1. Pre-therapy (Anytime between Day -21 and Cycle 1 Day 1) 
2. Cycle 3 Day 1 +/- 7 days 
3. Cycle 6 Day 1 +/- 7 days 
4. Cycle 9 Day 1 +/- 7 days 
5. Cycle 12 Day 1 +/- 7 days 
6. End of treatment +/- 7 days 
7. End of study +/- 7 days 
 
Collection procedure:  
• 
Draw one 10 ml Lavender EDTA tube and one 8.5 ml LBgard Blood Tube. 
• 
Draw the EDTA tube first and then LBgard Blood Tube second. 
• 
Completely fill the LBgard Blood Tube. 
• 
When draw the LBgard Blood Tube, follow the steps below to avoid possible backflow of 
chemical additives from the tube. 
o Place the subject’s arm in a downward position. 
o Hold tube in vertical position, below the donor’s arm during blood collection. 
o Release tourniquet as soon as blood starts to flow into tube. 
o Ensure that tube additives do not contact stopper or end of needle during venipuncture. 
• 
Ensure that the blood has stopped flowing into the tube before removing the tube from the 
holder. 
• 
Immediately after blood draw, gently invert the LBgard Blood Tube ten times. 
• 
The blood samples should be processed within 2 hours from collection. 
• 
If the blood samples cannot be processed within 2 hours from collection due to lack of 
institutional facility, draw the second LBgard blood tube in place of the EDTA tube and 
ship without any processing within 24 hours in room temperature.

Diagnostic imaging of affected and suspected sites (CT, MRI and/or photographs) will be done at Day 
1 of cycles 3, 6, 9, 12, and 15 (or between Day 15-21 of the prior cycle) in all patients. Diagnostic 
imaging will continue to be done every 2 months thereafter or as clinically indicated otherwise. 
 
 
 
 
 
An End of Treatment (EOT) visit will be performed for all subjects.  At the end of treatment (30 days 
after last Cemiplimab-rwlc dose) the following data will be collected: 
 
• 
Obtain vital signs. 
• 
Record all concomitant medication use.  
•

an additional 30 days beyond the EOT visit). 
• 
Diagnostic imaging of affected and suspected sites (CT, MRI and/or photographs), if not 
performed within the last 8 weeks. 
• 
Collect research blood sample 
 
 
 
 
 
To assess for late toxicities, at 6 months and 12 months after EOT patients will return for a 
physical exam and labs, unless the patient has enrolled in hospice care or is otherwise 
unwilling/unable to return to clinic.   
 
For this protocol, all patients, including those who discontinue protocol therapy early, will be 
followed for response until progression and for survival for 2 years from the start of treatment. All 
patients must also be followed through completion of all protocol therapy. Patients removed from 
study for unacceptable adverse events will be followed until resolution or stabilization of the 
adverse event.  Follow-up for survival will be performed every 90 days (± 2 weeks) from the end of 
treatment visit.

Immuno-oncology agents are associated with AEs that can differ in severity and duration than AEs 
caused by other therapeutic classes. Cemiplimab-rwlc is considered an immune-oncology agent in 
this protocol. Early recognition and management of AEs associated with immuno-oncology agents 
may mitigate severe toxicity. Management Algorithms have been developed to assist investigators in 
assessing and managing the following groups of AEs: 
• 
Gastrointestinal 
• 
Renal 
• 
Pulmonary 
• 
Hepatic 
• 
Endocrinopathy 
• 
Skin 
• 
Neurological 
The above algorithms can be found in Appendix 1

Cemiplimab-rwlc is an FDA approved drug for treatment of CSCC. Study participant may choose to 
continue Cemiplimab-rwlc as per standard of care if indicated upon study closure.  
 
 
 
 
 
 
Study participants will be monitored closely based on clinical, laboratory and imaging studies as 
outlined in study calendar (Table 3).  Patients will be educated and encouraged to report any AEs 
and SAEs promptly.  All AEs and SAEs will be graded according to CTCAE v5.0 and recorded in 
patient’s charts and CRFs.  
 
 
 
 
An adverse event (AE) is defined as any untoward medical occurrence, including an exacerbation of 
a pre-existing condition, in a patient in a clinical investigation who received a pharmaceutical product.  
The event does not necessarily have to have a causal relation with this treatment.  Grade 1 toxicities 
and lab abnormalities not deemed clinically significant will not be collected.

A serious adverse event (SAE) is defined as any AE that results in death, is immediately life-
threatening, results in persistent or significant disability/incapacity, requires or prolongs patient 
hospitalization, is a congenital anomaly/birth defect, or is to be deemed serious for any other reason 
if it is an important medical event when based on appropriate medical judgement that may jeopardize 
the patient and may require medical or surgical intervention to prevent one of the other outcomes 
listed in the above definitions. 
 
In addition, all reports of spontaneous abortion, abuse, and/or drug dependency shall be considered 
as SAEs for regulatory reporting purposes. 
 
Patients may be hospitalized for administrative or social reasons during the study (e.g., days on which 
infusion takes place, long distance from home to site). These and other hospitalizations planned at the 
beginning of the study do not need to be reported as an SAE in case they have been reported at 
screening visit in the source data and have been performed as planned. 
 
 
 
Unanticipated adverse therapy effect, any serious adverse effect on health or safety, or any life-
threatening problem or death caused by, or associated with, if that effect, problem, or death was not 
previously identified in nature, severity, or degree of incidence or any other unanticipated serious 
problem associated with the therapy that relates to the rights, safety, or welfare of subjects.   
 
 
 
 
 
 
All AEs will be graded using the CTCAE 5.0 criteria.  
For AEs not included in the protocol-defined grading system, the following guidelines will be used to 
describe severity. 
 
Mild – Events require minimal or no treatment and do not interfere with the participant’s daily activities. 
Moderate – Events result in a low level of inconvenience or concern with the therapeutic measures. 
Moderate events may cause some interference with functioning. 
Severe – Events interrupt a participant’s usual daily activity and may require systemic drug therapy 
or other treatment. Severe events are usually potentially life-threatening or incapacitating. 
 
 
 
For all collected AEs, the clinician who examines and evaluates the participant will determine the AE’s 
causality based on temporal relationship and his/her clinical judgment. The degree of certainty about 
causality will be graded using the categories below. 
 
Related – The AE is known to occur with the study agent, there is a reasonable possibility that the 
study agent caused the AE, or there is a temporal relationship between the study agent and event. 
Reasonable possibility means that there is evidence to suggest a causal relationship between the 
study agent and the AE. 
Not Related – There is not a reasonable possibility that the administration of the study agent caused 
the event, there is no temporal relationship between the study agent and event onset, or an alternate

etiology has been established. 
 
 
 
 
The PI will be responsible for determining whether an AE is expected or unexpected. An AE will be 
considered unexpected if the nature, severity, or frequency of the event is not consistent with the risk 
information previously described for the study agent. 
 
 
 
The study participants will be monitored closely throughout the study for occurrence of AE or SAE. 
The patients will be educated regarding most comment AEs and SAEs and will be encouraged to 
report promptly.  
 
If AEs and SAEs occur, information to be collected includes event description, time of onset, clinician’s 
assessment of severity, relationship to study product, and time of resolution/stabilization of event. All 
AEs occurring during the study will be documented appropriately, regardless of relationship. All AEs 
will be followed to adequate resolution. 
 
Any medical condition that is present at the time that the participant is screened will be considered 
as baseline and not reported as an AE. However, if the study participant’s condition deteriorates 
at any time during the study, it will be recorded as an AE. Unanticipated problems will be recorded 
in the data collection system throughout the study. 
 
Events will be followed for outcome information until resolution or stabilization is achieved. 
 
 
 
 
 
 
All AEs occurring prior to initiation of Cemiplimab-rwlc therapy do not need to be reported. 
 
All AEs occurring after first administration of Cemiplimab-rwlc therapy and 30 days after last 
administration of Cemiplimab-rwlc will be considered as on treatment. All AEs will be collected and 
graded according to CTCAE v5.0, with the exception of Grade 1 laboratory abnormalities which will 
not be collected. All Grade 2 and above toxicities will be collected and documented by the investigator, 
but only Grade 3 toxicities deemed possibly, probably or definitely related to the study treatment will 
be reported on the appropriate CRFs/SAE reporting forms. Only SAEs will be reported to the PI and 
Regeneron Pharmaceuticals, Inc. All AEs, including those persisting after end of study treatment must 
be followed up until they have resolved or have been sufficiently characterized or the principal 
investigator decides to not further pursue them. 
 
Serious and non-serious AEs occurring later than 30 days after last administration of trial drugs will 
only be reported in case they are considered drug-related or trial (procedure) related. 
 
Deaths (unless they are considered drug-related or trial related) will not be reported as SAE when

Serious and non-serious AEs occurring after the subjects initiate subsequent treatment will only be 
collected if deemed related to cemiplimab-rwlc. 
 
 
 
 
All SAEs will be reported to the PI and Regeneron Pharmaceuticals, Inc. within 24 hours after 
identification and recorded in OnCore and Regeneron Pharmaceuticals, Inc. by the investigator. All 
deaths and immediately life-threatening events, whether related or unrelated to the study 
agent/procedure, will be recorded on the SAE Form and submitted to the PI and Regeneron 
Pharmaceuticals, Inc. within 24 hours of site awareness. All SAEs will be followed until satisfactory 
resolution or until the investigator deems the event to be chronic or the adherence to be stable. 
 
The reporting to Regeneron Pharmaceuticals will be done by email, medical.safety@regeneron.com. 
 
 
 
The study investigator will report to the PI unanticipated problems and it will be on the discretion of the 
PI whether to conduct an evaluation of an unanticipated problem and whether to report it to IRB.

Protocol Monitoring Committee (PMC): 
The PMC meets monthly and reviews accrual, patterns and frequencies of all adverse events, protocol 
violations and when applicable, internal audit results.  
 
The data and safety plan will define criteria for stopping the trial according to rules set forth by this 
protocol. This trial will be continuously monitored by the site PI and the research team at each 
participating institution. All participating sites will have a monthly teleconference calls to monitor any 
safely concerns. Safety and monitoring reports will be submitted to the PMC after completing the first 
2 cycles after the enrollment of initial 3 patients or more frequently if requested by the PMC.  No 
additional interim analyses will be conducted. A final safety and monitoring report including all 27 
patients will be submitted to the PMC within three months of completing the study enrollment. This 
protocol will be subject to periodic internal audits based on risk or as recommended by the PMC. 
 
 
 
Data will be captured in OnCore, Moffitt’s electronic Clinical Trials Database. For each participant 
enrolled, the electronic CRF must be completed by the assigned data manager or other authorized 
study staff. Any paper forms should be typed or filled out indelible ink and must be legible. Errors 
should be crossed out but not obliterated, the correction inserted, and the change initialed and dated 
by the investigator or his/her authorized delegate. This also applies to records for those patients who 
fail to complete the study. If a patient stops dosing or terminates from the study, the dates and reasons 
must be noted on the CRF. If a patient terminates from the study because of toxicity, thorough efforts 
should be made to clearly document the outcome. Regulatory documents and case report forms will 
be monitored internally according to Moffitt Cancer Center Monitoring Policies. Monitoring will be 
performed regularly by the MCC Clinical Monitoring Core for accuracy, completeness, and source 
verification of data entry, validation of appropriate informed consent process, reporting of SAEs, and 
adherence to the protocol, Good Clinical Practice (GCP) guidelines, and applicable regulatory 
requirements. The investigator should ensure the accuracy, completeness, legibility, and timeliness of 
the data reported to the Protocol Monitoring Committee. 
 
 
 
 
 
 
 
 
This is a single arm phase II clinical trial assessing the overall response rate of Cemiplimab-rwlc in 
immunocompromised patients with unresectable local recurrence and/or metastatic CSCC.   
 
 
 
We hypothesize that the response rate to Cemiplimab-rwlc in immunocompromised patients is 
clinically meaningful as observed in immunocompetent patients.

Cemiplimab-rwlc will be analyzed.   
 
 
 
 
 
 
The primary analysis of efficacy is based a one-sided exact test. 
 
 
 
The primary endpoint for efficacy analyses is the ORR. All response assessments are done by RECIST 
1.1 analysis of radiologic scans. In some patients, response assessments include photos and 
radiologic scans and evaluated by composite efficacy criteria (see Appendix 2). Clinical lesions will 
only be considered measurable when they are superficial (eg, skin nodules and palpable lymph nodes) 
and ≥10 mm (≥1 cm) diameter as assessed using calipers (e.g., skin nodules). In the case of skin 
lesions, documentation by color photography, including a ruler to estimate the size of the lesion, is 
recommended. Patients who are deemed as not evaluable according to RECIST 1.1 or inevaluable by 
the composite efficacy criteria will be considered as not reaching PR/CR for ORR. 
 
We expect to complete the accrual in 12 months and the total study duration will be 24 months. 
 
 
 
The secondary analyses of efficacy as measured by PFS and OS will be summarized by median 
and its 95% confidence interval using the Kaplan-Meier method. 
 
 
 
Safety observations and measurements including drug exposure, AEs, laboratory data, vital signs, 
and Eastern Cooperative Oncology Group (ECOG) performance status will be summarized and 
presented in tables and listings. 
 
 
 
A sample size of 27 achieves 83.8% power to detect a difference (P1-P0) of 0.18 using a one-sided 
exact test with a target significance level of 0.1000. The actual significance level achieved by this test 
is 0.0986. These results assume that the population proportion under the null hypothesis (P0) is 0.15. 
 
 
 
Medical and research records for this trial including but not limited to, hospital records, clinical and 
office charts, laboratory notes, will be maintained in compliance with regulatory and MCC (or 
participating) institutional requirements for the protection of confidentiality of participants. 
Investigators of the study will have access to records.

Data collection will be collected by investigators/clinical stuff under supervision of the PI. The 
investigator is responsible for ensuring the accuracy, completeness, legibility, and timeliness of the 
data reported. 
 
Copies of the electronic CRF (eCRF) will be provided for use as source documents and maintained 
for recording data for each participant enrolled in the study.  
 
Clinical data (including AEs and concomitant medications) and clinical laboratory data will be entered 
into Power Chart, a CFR Part 11-compliant data capture system provided by the Cerner. The data 
system includes password protection and internal quality checks, such as automatic range checks, to 
identify data that appear inconsistent, incomplete, or inaccurate. Clinical data will be entered directly 
from the source documents. 
 
 
 
 
Data will be captured in OnCore, Moffitt’s Clinical Trials Database. Regulatory documents and case 
report forms will be monitored internally according to Moffitt Cancer Center Monitoring Policies. 
Monitoring will be performed regularly to verify data is accurate, complete, and verifiable from source 
documents; and the conduct of the trial is in compliance with the currently approved 
protocol/amendments, Good Clinical Practice (GCP), and applicable regulatory requirements. 
 
To obtain access to OnCore, the External Site Coordination (ESC) office Coordinator will supply 
forms required to be completed by the site staff. Once the completed forms are received, the site 
coordinator will receive DUO access, logon/password, and information on how to access OnCore. 
The ESC office will provide OnCore training to the site once initial access is granted and on an 
ongoing basis, as needed. 
 
Following closure of the study, each participating center will maintain a copy of all site study records 
in a safe and secure location. The Coordinating Center will inform the investigator at each site at 
such time that the records may be destroyed. This will also follow each institution guidelines 
 
Study documents should be retained for a minimum of 10 years after the last approval of a marketing 
application in an International Conference on Harmonisation (ICH) region and until there are no 
pending or contemplated marketing applications in an ICH region or until at least 10 years have 
elapsed since the formal discontinuation of clinical development of the study intervention. These 
documents should be retained for a longer period, however, if required by local regulations. No 
records will be destroyed without the written consent of the sponsor, if applicable. It is the 
responsibility of the sponsor to inform the investigator when there is no longer a need for these 
documents to be retained. Permission must be acquired from the State of Florida for document 
destruction after the 10-year minimum record-retention period described above has elapsed.

29 Oct 2020 
 
The noncompliance may be either on the part of the participant, the investigator, or the study site 
staff. As a result of deviations, corrective actions are to be developed by the site and implemented 
promptly. 
 
These practices are consistent with ICH E6: 
• 
4.5 Compliance with Protocol, sections 4.5.1, 4.5.2, and 4.5.3 
• 
5.1 Quality Assurance and Quality Control, section 5.1.1 
• 
5.20 Noncompliance, sections 5.20.1, and 5.20.2. 
 
It is the responsibility of the site to use continuous vigilance to identify and report deviations within 7 
working days of identification of the protocol deviation, or within 7 working days of the scheduled 
protocol-required activity. Protocol deviations must be sent to the local IRB per their guidelines. The 
site PI/study staff is responsible for knowing and adhering to their IRB requirements. Further details 
about the handling of protocol deviations will be included in the MOP. 
 
 
 
 
This study will comply with the NIH Public Access Policy, which ensures that the public has access 
to the published results of NIH funded research. It requires scientists to submit final peer-reviewed 
journal manuscripts that arise from NIH funds to the digital archive PubMed Central upon 
acceptance for publication. 
 
The International Committee of Medical Journal Editors (ICMJE) member journals have adopted a 
clinical trials registration policy as a condition for publication. The ICMJE defines a clinical trial 
as any research project that prospectively assigns human subjects to intervention or concurrent 
comparison or control groups to study the cause-and-effect relationship between a medical 
intervention and a health outcome. Medical interventions include drugs, surgical procedures, 
devices, behavioral treatments, process-of-care changes, and the like. Health outcomes include 
any biomedical or health-related 
measures obtained in patients or participants, including 
pharmacokinetic measures and adverse events. The ICMJE policy, and the Section 801 of the 
Food and Drug Administration Amendments Act of 2007, requires that all clinical trials be 
registered in a public trials registry such as ClinicalTrials.gov, which is sponsored by the National 
Library of Medicine. Other biomedical journals are considering adopting similar policies. For 
interventional clinical trials performed under NIH IC grants and cooperative agreements, it is the 
grantee’s responsibility to register the trial in an acceptable registry, so the research results may 
be considered for publication in ICMJE member journals. The ICMJE does not review specific 
studies to determine whether registration is necessary; instead, the committee recommends that 
researchers who have questions about the need to register err on the side of registration or consult 
the editorial office of the journal in which they wish to publish. 
 
FDAAA mandates that a "responsible party" (i.e., the sponsor or designated principal 
investigator) register and report results of certain "applicable clinical trials": 
 
• 
Trials of Drugs and Biologics: Controlled, clinical investigations, other than Phase I 
investigations, of a product subject to FDA regulation; 
• 
Trials of Devices: Controlled trials with health outcomes of a product subject to FDA

regulation (other than small feasibility studies) and pediatric postmarket surveillance 
studies. 
 
NIH grantees must take specific steps to ensure compliance with NIH implementation of FDAAA. 
 
It is understood that any manuscript or releases resulting from the collaborative research will be 
circulated to all participating sites prior to submission for publication or presentation. The Protocol 
Chair will be the final arbiter of the manuscript content. 
 
 
 
 
 
 
Protocol Monitoring Committee (PMC) 
 
The PMC meets monthly and reviews accrual, patterns and frequencies of all adverse events, 
protocol violations and when applicable, internal audit results. 
 
The Protocol Chair is responsible for monitoring the study. Data must be reviewed to ensure the 
validity of data, as well as the safety of the participants. The Protocol Chair will also monitor the 
progress of the trial, review safety reports, and clinical trial efficacy endpoints and to confirm that 
the safety outcomes favor continuation of the study. 
 
The Protocol Chair will be responsible for maintaining the clinical protocol, reporting adverse events, 
ensuring that consent is obtained and documented, reporting of unexpected outcomes, and 
reporting the status of the trial in the continuing renewal report submitted to the IRB and to the trial 
monitoring review group. Content of the continuing renewal report at a minimum should include year-
to-date and full trial data on the following: accrual and eligibility, protocol compliance, treatment 
administration, toxicity and ADR reports, response, survival, regulatory compliance, and compliance 
with prearranged statistical goals. The report should be submitted in a timely manner according to 
the schedule defined by the Moffitt Cancer Center Institutional Review Board. 
 
Regulatory documents and case report forms will be monitored internally according to Moffitt Cancer 
Center Monitoring Policies. Monitoring will be performed regularly by the MCC Clinical Monitoring 
Core for accuracy, completeness, and source verification of data entry, validation of appropriate 
informed consent process, reporting of SAEs, and adherence to the protocol, Good Clinical Practice 
(GCP) guidelines, and applicable regulatory requirements. 
 
 
 
 
 
 
Before the study can be initiated at any site, the site will be required to provide regulatory 
documentation to the External Site Coordination (ESC) office at Moffitt Cancer Center. Sites must 
provide a copy of their informed consent to the ESC office for review and approval prior to 
submission of any documents to the site’s IRB. Any changes requested by the site’s IRB must be

APPENDIX 1: MANAGEMENT ALGORITHMS 
 
These general guidelines constitute guidance to the Investigator and may be supplemented at the 
discretion of the treating physician. The guidance applies to all immuno-oncology agents and 
regimens. 
 
A general principle is that differential diagnoses should be diligently evaluated according to standard 
medical practice. Non-inflammatory etiologies should be considered and appropriately treated. 
 
Corticosteroids are a primary therapy for immuno-oncology drug-related adverse events. The oral 
equivalent of the recommended IV doses may be considered for ambulatory patients with low-grade 
toxicity. The lower bioavailability of oral corticosteroids should be taken into account when switching 
to the equivalent dose of oral corticosteroids. 
 
Consultation with a medical or surgical specialist, especially prior to an invasive diagnostic or 
therapeutic procedure, is recommended. 
 
The frequency and severity of the related adverse events covered by these algorithms will depend on 
the immuno-oncology agent or regimen being used. 
 
Patients will not be able to resume treatment following events that require Cemiplimab-rwlc to be 
discontinued for more than 84 days (12 weeks) from last scheduled dose. Reference the Dose 
Adjustments/Modifications/Delays section for additional details.

• Colitis 
• Colitis 
microscopic 
• Enterocolitis 
hemorrhagic 
• GI perforation 
• Necrotizing 
colitis 
• Diarrhea:  
All patients who 
experience 
diarrhea should 
be advised to 
drink liberal 
quantities of clear 
fluids. If sufficient 
oral fluid intake is 
not feasible, fluid 
and electrolytes 
should be 
substituted via IV 
infusion. 
≤Grad
e 1 
No change in 
dose 
• For diarrhea, treat symptomatically (loperamide, oral 
hydration, electrolyte substitution and ADA colitis diet). 
Endoscopy is recommended if symptoms persist. 
• Grade 1 diarrhea that persist for >1 week should be treated 
with the addition of oral diphenoxylate hydrochloride and 
atropine sulfate four times daily and budesonide 9 mg daily. 
Grade 
2 
Hold until 
<Grade 1. 
Resume at 
same dose. 
• GI consultation and endoscopy is recommended to confirm 
or rule out colitis for grade 2 diarrhea that persists >1 week 
or grade 1-2 diarrhea with rectal bleeding (additional 
guidelines for the treatment of persistent colitis are provided 
below). 
• Grade 2 diarrhea should be treated with the addition of oral 
diphenoxylate hydrochloride and atropine sulfate four times 
daily and budesonide 9 mg daily. 
• Grade 2 diarrhea with diffuse ulceration and bleeding seen 
on endoscopy may require oral steroids with prolonged 
taper and represent an increased risk for the development 
of bowel perforation. Consider prophylactic antibiotics for 
opportunistic infections. 
• When symptoms improve to Grade 1 or less, steroid taper 
should be started and continued over no less than 4 weeks. 
• In patients with Grade 2 enterocolitis, cemiplimab should be 
withheld and antidiarrheal treatment should be started. If 
symptoms are persistent for more than one week, systemic 
corticosteroids should be initiated (eg, 0.5 mg/kg/day of 
prednisone or equivalent). When symptoms improve to 
Grade 1 or less, corticosteroid taper should be started and 
continued over at least 1 month.

• In patients with Grade 3 enterocolitis, cemiplimab will be 
permanently discontinued and treatment with systemic 
corticosteroids should be initiated at a dose of 1–2 
mg/kg/day of prednisone or equivalent. When symptoms 
improve to Grade 1 or less, corticosteroid taper should be 
started and continued over at least 1 month. Consider 
prophylactic antibiotics for opportunistic infections. 
For Grade 3–4 diarrhea (or Grade 2 diarrhea that persists 
after initial steroid treatment), 
• Rule out bowel perforation. Imaging with plain films or 
computed tomography (CT) can be useful.  
• Consider consultation with gastroenterologist and 
confirmation biopsy with endoscopy. 
• Treat with intravenous (IV) steroids (methylprednisolone 125 
mg) followed by high-dose oral steroids (prednisone 1–2 
mg/kg once per day or dexamethasone 4 mg every 4 hours). 
When symptoms improve to Grade 1 or less, steroid taper 
should be started and continued over no less than 4 weeks. 
Taper over 6–8 weeks in patients with diffuse and severe 
ulceration and/or bleeding.

• If IV steroids followed by high dose oral steroids does not 
reduce initial symptoms within 48–72 hours, consider 
treatment with infliximab at 5 mg/kg once every 2 weeks. 
Discontinue infliximab upon symptom relief and initiate a 
prolonged steroid taper over 45–60 days. If symptoms 
worsen during steroid reduction, initiate a retapering of 
steroids starting at a higher dose of 80 or 100 mg followed 
by a more prolonged taper and administer infliximab. 
CAUTION: infliximab is contraindicated in patients with 
bowel perforation or sepsis. 
• If symptoms persist despite the above treatment a surgical 
consult should be obtained.

APPENDIX 2: COMPOSITE RESPONSE CRITERIA FOR PATIENTS WITH LOCALLY ADVANCED 
CSCC 
 
These criteria are designed primarily for patients whose target lesions will be evaluated by 
clinical measurements (ie caliper or ruler measurements).  This appendix also provides composite 
response criteria for disease that is measurable by both clinical response criteria and radiographic 
images.  These patients will be followed by clinical measurements and will also undergo 
radiologic imaging at baseline, and this will also be performed serially at each response assessment 
unless the investigator deems that baseline radiologic imaging was uninformative.  Radiologic 
imaging will be essential in the evaluation of tumors that have subdermal components that cannot be 
adequately assessed by clinical measurements. 
 
A new cutaneous lesion consistent with CSCC will be considered as PD if the lesion is ≥10 mm in 
both maximal perpendicular diameters, and can be clearly documented as not being previously 
present, unless it is confirmed on biopsy not to be consistent with CSCC. If a new cutaneous lesion 
is not biopsied or if the histology is inconclusive, it should be considered CSCC and deemed PD. 
 
Composite Response Criteria 
These criteria are for patients who have locally advanced or metastatic CSCC that is measurable by 
BOTH clinical response criteria by clinical measurement and radiologic imaging.

You are being asked to take part in a research study.  The information in this document should 
help you to decide if you would like to participate. 
The purpose of this research study is to determine how people with weakened immune systems 
and unresectable (cannot be removed by surgery) locally recurrent and/or metastatic cutaneous 
squamous cell carcinoma (CSCC) respond to study treatment with Cemiplimab. Cemiplimab is 
approved for sale in United States by the U.S. Food and Drug Administration (FDA).  About 27 
participants will participate in this study. 
During the study, you will receive Cemiplimab study treatment that will be administered every 21 
days for approximately 1 year (17 cycles).  Each study treatment will be administered 
intravenously for approximately 30 minutes.  You will stop receiving study treatment prior to 1 
year if your disease progresses, you experience intolerable side effects, or you withdraw your 
consent for study participation.   
Some of the most common side effects of Cemiplimab include fatigue, nausea, diarrhea, 
constipation, decreased appetite, and rashes. Cemiplimab can also cause side effects called 
immune-related adverse reactions.  These side effects can be serious and require corticosteroid 
treatment or discontinuation of the study medication. Some examples of these immune-related

side-effects are pneumonitis (inflammation of the lung), colitis (inflammation of the colon), and 
hepatitis (inflammation of the liver).  Please see the “ARE THERE RISKS TO ME IF I AM IN 
THIS STUDY” section of this form for additional immune-related side effects.  Other potential 
serious side effects include, but are not limited to, diabetic ketoacidosis (a potentially dangerous 
buildup of acids in your blood), damage to the liver, infusion related reactions, and Guillain-
Barre Syndrome (damage to the nervous system).  Please review the “ARE THERE RISKS TO 
ME IF I AM IN THIS STUDY?” section of this form for additional information on Cemiplimab side 
effects.  
In addition to receiving the study drug, throughout the study you will visit the clinic and undergo 
the following procedures:  you will be asked questions about your medical history and any 
medications you are currently taking; you will be asked questions about any symptoms you may 
be experiencing; you will complete physical exams and your vital signs will be assessed; you 
will complete laboratory tests; you will complete a pregnancy test, if applicable; you will undergo 
imaging studies (CT/MRI); and you may provide an optional tumor biopsy.  Additional 
information about the study procedures can be found in the “WHAT WILL HAPPEN DURING 
THIS STUDY?” section of this form.  
Your participation is voluntary, and you may stop your participation at any time.  There will be no 
penalties or loss of benefits or opportunities if you do not participate or decide to stop once you 
start.  Any new important information that is discovered during the study which may influence 
your willingness to continue participation will be provided to you. 
We do not know if you will receive any benefit from your participation.  There is no cost to 
participate.  You will not be compensated for your participation.   
Even if we publish the findings from this study, we will keep your study information private and 
confidential.  Anyone with the authority to look at your records must keep them confidential. 
 
WHAT IS THIS STUDY ABOUT? 
You are being asked to participate in this research study because you have a weakened 
immune system and unresectable (cannot be removed by surgery) locally recurrent and/or 
metastatic cutaneous squamous cell carcinoma (CSCC).  
The purpose of this research study is to: 
• 
test the safety and effectiveness of the study drug, Cemiplimab.    
This research study will test the investigational drug, Cemiplimab.  Cemiplimab is approved by 
the United States Food and Drug Administration (FDA) for the treatment of patients with 
metastatic cutaneous squamous cell carcinoma (CSCC) or locally advanced CSCC who are not 
candidates for curative surgery or curative radiation.  This study is designed to test the safety of 
Cemiplimab and to see how your type of cancer responds to Cemiplimab study treatment in 
participants with weakened immune systems.

• 
You will be asked questions about your medical history 
• 
You will be asked questions regarding any symptoms you may be having  
• 
You will be asked questions about your daily activities  
• 
Your vital signs will be taken 
• 
You will complete a physical exam 
• 
Blood will be collected for laboratory tests 
• 
You will complete a pregnancy test, if applicable 
• 
You will complete a computed tomography (CT)/magnetic resonance imaging (MRI) 
scan of the head/neck/chest/abdomen/pelvis and other areas where your cancer is. You 
may also have photographs taken of your cancer, if visible. 
• 
You will provide an archived tumor sample (tissue from a previous biopsy or surgery) 
• 
You will be asked to provide an optional, new tumor biopsy sample 
• 
You will be asked about any medications you may be taking 
• 
You will provide demographic information (such as age, gender, etc.) 
If you qualify to take part in this study and go on to receive the study treatment then the 
following will happen: 
Study Treatment:  
You will receive Cemiplimab every 21 days for approximately 1 year (17 cycles).  Each study 
treatment will be administered intravenously (directly into your vein) for approximately 30 
minutes.  You will stop receiving study treatment prior to 1 year if your disease progresses, you 
experience intolerable side effects or you withdraw your consent for study participation.  
Because this is a research study, the study drug will be given to you only during this study and 
not after the study is over. 
During the study treatment portion of the study, you will continue to come to the clinic for study 
visits and undergo the following procedures: 
• 
You will complete physical exams 
• 
Your vital signs will be taken 
• 
Blood will be collected for laboratory tests 
• 
You will complete CTs/MRIs of the head/neck/chest/abdomen/pelvis and other areas 
where your cancer is. You may also have photographs taken of your cancer, if visible.  
• 
You will be asked about any medications you are taking 
• 
You will be asked about any symptoms you may be experiencing 
End of Study Treatment Visit: 
An end of study treatment visit will be performed once you end the study treatment period for 
any reason (your disease progresses, you have harmful side effects, or if you with withdraw 
your consent to participate in the study).  This visit will take place approximately 30 days after 
your last dose of Cemiplimab.  During this visit, the following procedures will be performed:

you have had these procedures performed recently, it may not be necessary to repeat. 
Final Study Visit: 
At the end of the study (about 24 months after your first dose of Cemiplimab) you will complete 
a final study visit.  During this visit, the following procedures will be performed: 
• 
Blood will be collected for research purposes 
Follow-Up Study Visits: 
You will return to the study clinic approximately 6 months and 12 months after your end of 
treatment visit for a physical exam and laboratory tests 
Additional information on the required study procedures can be found below: 
• 
Demographic Questions:  you will be asked to give personal information, such as your 
name, date of birth, and race. 
• 
Health and Medication Questions: you will be asked to answer questions about your 
health, your medical history, and the medications you take. 
• 
Physical Exam:  a comprehensive physical exam, including a neurological evaluation, 
will be performed.  You should ask you study doctor to explain what will happen during 
this exam. 
• 
Vital Signs:  the study team will check your blood pressure by putting a band around 
your arm (this will squeeze your arm for about a minute), check your pulse, listen to you 
breathe in and out, and will take your temperature.  Your height and weight will also be 
assessed. 
• 
Blood Testing:  blood will be collected for laboratory tests 
o Some of your blood will be used to check on your health. 
o Some of your blood will be used for research purposes. 
• 
Pregnancy Testing:  a blood or urine test will be performed to see if you are pregnant.  
You will only have pregnancy testing if you are a woman and can have children.  The 
study doctor or study staff will tell you if the pregnancy test results are positive.  The 
results of the pregnancy testing must be negative in order for you to be in the study. 
• 
CT Scan:  A CT scan uses radiation (x-rays) to make pictures of the inside of your body.  
The scan can show a cross-section (a thin “slice”) of your body, or can show the body 
tissues and structure in 3 dimensions (“3-D”).  The study doctor or study staff may give 
you a contrast dye, either by mouth or with a needle.  The study doctor can tell you more 
about contrast dye. 
• 
MRI:  An MRI uses powerful magnets and radio waves to make pictures of body tissues 
and structure.

• 
Optional Biopsies: If you agree, a tissue sample will be collected, prior to receiving the 
study drug (during the screening portion of the study) and at the end of the study. The 
information obtained from these samples will be used for future research of your 
disease.  You do not have to provide the samples in order to participate in this study.  
You will be asked to provide your consent to the optional biopsies at the end of this 
consent form.   
 
HOW WILL MY SAMPLES BE USED? 
In addition to the procedures outlined above, we are asking you to allow us to store your 
optional tumor biopsies and blood samples, collectively referred to as “tissue”, for use in 
future research.  These samples may be used for research on your disease or condition and 
others to assist in the development of new treatments. 
In addition to your samples being used for this study and future research, we would like to 
share them with other researchers.  We will code your samples so that the researcher who 
uses it for other purposes does not know your identity.  We will not release the code that 
links your sample to your personal identifying information for any reason. 
This study also involves genetic testing.  Genes control how your body grows and changes, and 
how your body reacts to certain things.  Genes are what we get from our parents that help make 
our bodies what they are.  For example, eye and hair color depend on the genes we received 
from our parents.  We want to find out how genes work in skin cancer.  It may be true that some 
people are more likely to have skin cancer because of their genes and we would like to learn 
more about this. 
As part of this study, a blood sample will be obtained and DNA from your blood sample will be 
purified.  DNA, or deoxyribonucleic acid, stores and transmits inherited traits, such as eye color 
or blood type.  As part of this research project, your DNA will be studied in an effort to find out if 
there are genes that contribute to medical conditions that are part of this study. 
We will not tell you what we find out about your genes.  For example, we might find out that you 
have a certain kind of gene.  We may know that if people have this gene, they sometimes get a 
certain disease or do not respond to treatment.  You could have a gene that makes it more likely 
that you will have a health problem.  However, that does not mean you will get that health 
problem.  You should ask the study team or a genetic counselor if you have any questions 
about genetic research. 
Your sample will be stored with your name or other identifying information and health 
information linked to it.  We will not share your name or other information that identifies you 
unless it is required by law.  Since your genetic sample is linked to identifying information, 
should you choose to withdraw your consent to use the sample at a later date, please contact 
the study team.  The study team will remove your sample from the research and immediately 
destroy it so that it can no longer be used.  Please understand that part of your sample may 
have been used prior to the withdrawal of your consent. 
Researchers can look closely at large amounts of your genetic information by sequencing, or 
“reading”, every letter in your DNA (your genome).  Reading a person’s entire genetic code is 
called whole genome sequencing.  The research will include whole genome sequencing (i.e.,

sequencing of a human germline or somatic specimen with the intent to generate the genome or 
exome sequence of that specimen). 
As part of the genetic study, a sample of your DNA may have Genome Wide Association 
Studies (GWAS) performed.  This analysis creates a very detailed picture of your DNA for 
researchers.  In addition, information regarding your DNA and clinical information about you will 
be sent to the National Institute for Health’s Genome Wide Association Study (GWAS) data 
repository, where it will undergo genome-wide analysis and be shared with other investigators 
for research purposes.  DNA and information sent to the GWAS database will help researchers 
better understand how genes affect the risk of developing diseases and may lead to better 
methods to select the best treatment options.  Before your information is sent to the GWAS data 
repository it will be de-identified, which means that we will remove any identifying information 
such as your name, date of birth, address, etc.  Thus, researchers using your DNA and clinical 
data will not be able to link this information back to you. 
Genetic Information Nondiscrimination Act (GINA) 
A Federal law, called the Genetic Information Nondiscrimination Act (GINA), generally makes it 
illegal for health insurance companies, group health plans, and most employers to discriminate 
against you based on your genetic information.  This law generally will protect you in the 
following ways: 
• 
Health insurance companies and group health plans may not request your genetic 
information that we get from this research. 
• 
Health insurance companies and group health plans may not use your genetic 
information when making decisions regarding your eligibility or premiums. 
• 
Employers with 15 or more employees may not use your genetic information that we get 
from this research when making a decision to hire, promote, or fire you or when setting 
the terms of your employment. 
All health insurance companies, group health plans, and employers as outlined above must 
follow this law.  Please note that this new Federal law does not protect you against genetic 
discrimination by companies that sell life insurance, disability insurance, or long-term care 
insurance. 
 
WHO IS PAYING FOR THIS STUDY? 
A company called Regeneron Pharmaceuticals, Inc., the manufacturer of the study drug, is 
paying for this study. 
 
WILL IT COST ANYTHING TO BE IN THIS STUDY? 
You and/or your insurance company will be financially responsible for hospital inpatient, 
outpatient and follow-up visits that would normally or routinely occur in the management of your 
disease.  Inpatient and outpatient visits could include charges for treatments, medications, 
physician visits, laboratory tests and procedures.   You and /or your insurance company will be 
responsible for paying for the charges which are considered routine, since you would have 
received these services even if you were not participating in this study.   You will be responsible 
for any costs not covered by your insurance company, including deductibles, co-payments and

all out-of-pocket expenses. Before you agree to be in this study, you should contact your health 
insurer to see if your plan will cover the costs required as part of your participation.   
 
You and/or your insurance company will not be responsible for paying for study related items 
and services that are specifically required for this research study and are not considered part of 
the routine management of your disease, if these procedures are performed at Moffitt Cancer 
Center.   
 
During your participation in this study, the study sponsor will be responsible for providing the 
study drug, Cemiplimab, at no additional charge to you. You and/or your insurance company will 
be responsible for the charges related to the administration of the study drug. 
If you would like more information on the costs of being on this study or have other insurance 
related questions then please let your clinical trial coordinator know or contact our Business 
Office at 813-745-8422. 
 
WILL BEING IN THIS STUDY HELP ME? 
You may benefit as a result of your participation in this study.  There is, however, no guarantee 
that you will benefit from your participation in this study.  Information learned from the study may 
help other people in the future. 
 
ARE THERE RISKS TO ME IF I AM IN THIS STUDY? 
The Cemiplimab might not help. 
Right now, we do not know for sure if Cemiplimab will help.  If it does not help, your 
condition/disease may get worse. 
You may have problems because of the Cemiplimab.  These problems are called side effects.  
Some side effects are just bothersome.  Others could harm you.  There may be some side 
effects that we do not know about yet.  The research might involve risks to you that are currently 
unforeseeable.  Your health care team may give you medicines to help lessen side effects.  
Many side effects go away soon after you stop taking the study drug.  In some cases, side 
effects can be serious, long lasting, or may never go away. There may also be the risk of death. 
 
HERE ARE THE KNOWN SIDE EFFECTS THAT COULD HAPPEN WITH CEMIPLIMAB

ALTERNATIVE TREATMENTS 
Some potential alternatives to participating in the study are palliative chemotherapy or 
cetuximab.  
As with any medication or chemotherapy treatment, there may be risks, known and unknown. 
The most common temporary side effects for some chemotherapy drugs may include nausea 
and vomiting, loss of appetite, hair loss, mouth sores, higher risk of infection (due to decreased 
white blood cells), bruising or bleeding, fatigue (feeling tired), and changes in your menstrual 
cycle if you are a woman, (such as, irregular periods or symptoms of menopause [end of 
menstruation]). 
A more complete listing of side effects for other therapies may be available for you to review if 
you wish.  Please talk with your study doctor about the risks of both this investigational drug and 
any alternative methods of treatment that are available. 
 
WHAT CAN HAPPEN IF I GET INFUSIONS? 
The study doctor will give you the study drug by sticking a needle in your skin.  Some problems 
you might have from this are: 
• 
Pain 
• 
Bruising 
• 
Dizziness 
• 
Infection 
You will receive the study drug intravenously, which means you will receive it directly into your 
vein.  This may cause the following problems: 
• 
Irritation of the vein; your skin near the vein could become warm, swell, hurt, or get red 
• 
Damage to your vein 
• 
Damage to the skin or tissue around the injection site 
• 
Too much of the study drug may be given to you 
• 
An increase or decrease in electrolyte levels (the amount of certain salts and other 
chemicals in your blood), could occur which could cause health problems 
• 
A blood clot or an air bubble could form, which could block a blood vessel in another part 
of your body 
Some of these problems could be very serious. 
Over time, getting a lot of injections can cause a vein to become hard or scar, which can make it 
difficult to put a needle into the vein to give you a shot or take blood. 
 
COULD I HAVE AN ALLERGIC REACTION? 
Occasionally, people have allergic reactions to medications which may require medical 
treatment.  A severe allergic reaction could be life-threatening.  Examples of an allergic reaction 
include: a rash; shortness of breath; wheezing; difficulty breathing; sudden drop in blood 
pressure; swelling around the mouth, throat, or eye; fast pulse; and sweating.  You should get

immediate medical help and contact the study doctor if you have any of these or any other side 
effects during the study. 
 
IS THERE ANY RISK TO YOUR UNBORN CHILDREN IF YOU TAKE PART IN THIS STUDY? 
FOR WOMEN: 
If you are pregnant, you cannot participate in this study, because there may be risks to you and 
your unborn baby that are currently unforeseeable; risks that we do not know about yet.  
Breastfeeding (nursing) mothers will not be included in this study, since it is not known whether 
the study drug will be passed on to the baby in mother’s milk.  If you are currently breastfeeding 
and wish to continue breastfeeding, your study doctor may recommend another treatment. 
If you are a woman of childbearing potential (able to become pregnant), you will be given a 
pregnancy test before beginning any study drug. 
Tell the study doctor right away if: 
• 
You are pregnant. 
• 
You become pregnant. 
• 
You are planning to become pregnant. 
• 
You are breastfeeding. 
FOR MEN AND WOMEN: 
Whether you are a man or a woman, there may be risks to your unborn children that we don’t 
know about ahead of time; they are unforeseeable. 
If you take part in this study, you must use an effective birth control method as discussed with 
your study doctor and continue to use it until at least 6 months after your last dose of study 
drug. 
Examples of birth control methods include: 
• 
Oral birth control pills 
• 
Birth control patch 
• 
Implanted (injectable contraceptive hormones or mechanical products such as 
intrauterine device) 
• 
Barrier methods (such as: diaphragm, condoms, or spermicides) 
• 
Tubal ligation or vasectomy 
• 
Abstinence (no sexual intercourse) 
You should discuss the method of birth control which is best for you to use both during study 
treatment and for a period of time after study treatment. 
Whether you are a woman or a man, you should tell your study doctor immediately if you 
become pregnant or if your partner becomes pregnant.  Women who become pregnant during 
the study will have to leave the study.   
The long-term effects of the study drug on fertility are unknown.  This means that it is unknown if 
the study drug will affect your ability to have children in the future.  If we find out that the study 
drug might harm your fertility, you will be informed.

Cancer treatment can affect fertility in both men and women, and it is important to understand 
the risks before starting study therapy.  Ask your study staff about fertility preservation before 
you begin study treatment.  However, once you have started study treatment you should not 
donate or sell your eggs or sperm. 
 
COULD I HAVE ANY OTHER PROBLEMS WITH MY HEALTH IF I DO THIS RESEARCH 
STUDY? 
It is possible that you could have problems and side effects of Cemiplimab that nobody knows 
about yet, which include your cancer getting worse or even death.  If the study doctor learns any 
new 
 information that might change your mind about continuing in the study, the study doctor or 
study staff will tell you about it.  The study doctor will also tell you if new treatments become 
available for your cancer. 
It is possible that taking Cemiplimab with your regular medications or supplements may change 
how, the study drug or your regular medications, or regular supplements work.  It is very 
important that you tell the study doctor about all medications or supplements you are taking 
during the study. 
 
WHAT ARE THE RISKS OF GIVING BLOOD FOR THIS STUDY? 
Risks associated with drawing blood from your arm include momentary discomfort and/or 
bruising.  Infection, excess bleeding, clotting, or fainting are also possible, although unlikely. 
You will give about 20 ml (4 teaspoons) of blood for research purposes at screening, at the start 
of cycles 3, 6, 9 and 12, at End of Study Treatment (EOST), and End of Study (2 years after 
your first study treatment).  In total, this will amount to approximately 140 ml (about 9 
tablespoons) of blood.  
 
WHAT ARE THE RISKS OF HAVING A BIOPSY DONE FOR THIS STUDY? 
Optional Tumor Biopsy 
Risks of a tumor biopsy are localized bleeding at the needle injection site or from the surgical 
incision, pain, inflammation, swelling, and infection.  The bleeding may cause discomfort and 
bruising.  In rare circumstances (less than 1%), this bleeding may be severe enough to require 
further care.  If you have a history of excessive bleeding, or if you are receiving medication that 
might increase your risk of bleeding (such as aspirin or blood thinners), you must notify the 
study doctor before the procedure.  Infection of the surgical site may require treatment with 
antibiotics. 
Tumors that are biopsied from the lungs may result in an additional risk of pneumothorax 
(collapsed lung).  Biopsies in or near other vital organs may result in bleeding that can be life-
threatening or may cause damage to the organs and affect their function.   
Depending on the site, the biopsy procedure may use local anesthetics (numbing medicine), 
sedatives, or general anesthesia to reduce the discomfort or pain.  All medicines have the 


MCC #: 20114 
 
 
 
 
 
 Version 3 version date: 07/23/2020

   Page 13 of 19 
 
possible risk of allergic reaction.  Please advise your study doctor if you have ever had an 
allergic reaction to latex, lidocaine, or any other anesthetic.   
Any complications arising from the biopsy may be treated with observation, additional 
medications, or in some cases, additional surgery.  The study doctor will discuss the specific 
risks of the biopsy with you at the time of the procedure. 
Liver Biopsy 
For participants undergoing an optional liver biopsy, there may be increased risk in certain 
circumstances.  When study doctors perform your liver biopsy, they do so by passing a needle 
into the liver usually through your side.  Doctors are usually able to get a large enough piece of 
liver to examine under the microscope by taking a single biopsy of the liver.  However, in some 
participants, only a small piece is retrieved (not enough to look at under the microscope) and in 
this case, a second specimen from the liver is taken for clinical diagnosis.  However, after the 
first attempt, if there is enough for clinical purposes, but not for research purposes, a second 
piece will be taken for research purposes.  Thus, by participating in this study, in a small fraction 
of participants undergoing liver biopsy (less than 5% of all participants), there will be a chance 
that a second piece of liver will be taken for research purposes.  The additional risk of an 
additional liver sampling is approximately 1 in 1,000 for increased bleeding, and 1 in 2,000 for 
other complications such as puncture of a lung or colon.  These complications are managed by 
observation and, in some circumstances, surgery. 
Skin Biopsy 
A skin biopsy is generally a non-hazardous procedure; however, possible hazards may include: 
1) reaction to anesthetic (numbing medicine), 2) excessive bleeding, 3) bruising, 4) infection and 
5) excessive scarring.  While the local numbing medicine xylocaine is almost entirely free from 
allergic properties (such as causing hives), an allergic reaction is possible, and you will not be 
given xylocaine if you have a history of such a reaction.  The xylocaine will be given by a small 
injection into the skin at the site of the skin biopsy.  To speed healing, one or two stitches (also 
known as sutures) will be placed, which will be removed 5 - 7 days later.  During the healing 
process, you will be asked to keep the biopsy site clean and dry, and to apply antibiotic 
ointment.  Infection rarely occurs and is largely prevented by the use of an aseptic (or sterile) 
biopsy technique and proper wound care. If infection does occur, you will be instructed to keep 
the wound clean and to apply warm, wet compresses for 15 minutes, three times a day, until the 
infection subsides.  If the infection persists, antibiotics may be prescribed. 
Only 10-15 minutes will be required for the biopsy procedure.  After the anesthesia wears off, 
there will be some soreness at the biopsy site that will last for a few hours.  A small scar will 
develop at the site of the biopsy. 
 
WHAT ARE THE RISKS OF OTHER STUDY PROCEDURES? 
MRI 
Magnetic resonance imaging (MRI) uses a magnet and radio waves to make diagnostic medical 
images of the body.  There have been no ill effects reported from exposure to the magnetism or 
radio waves used in this test.  However, it is possible that harmful effects could be recognized in 
the future.  A known risk is that the magnet could attract certain kinds of metal.  Therefore, we 
will ask you about metal within your body, including medical implants, devices such as

pacemakers and internal defibrillators, or certain dyes found in tattoos.  We will also keep the 
examining room locked so that no one carrying metal objects can enter while you are in the 
scanner. 
If there is any question about potentially hazardous metal within your body, you will not undergo 
the MRI.  This may exclude you from participation in this research study.  The MRI involves 
entering a large room in which a magnet is present.  You will be placed on a narrow bed and 
then slid into a small tunnel approximately 6 feet in length and 25 inches in diameter.  You will 
be asked to lie still for about one hour on this bed.  You will hear a loud machine-like noise.  You 
may be asked to have a harmless monitoring device applied during the MRI.  During the MRI, 
you can have voice contact and physical contact with someone in attendance if you desire.  Let 
the study doctor know if you have a fear of enclosed spaces. 
CT Scan 
Computed Tomography (CT) is a way to make x-ray images of the inside of the body.  The CT 
scanner is a doughnut-shaped machine that uses x-rays to create computer pictures that show 
structures inside your body more clearly than regular x-ray pictures.  During the procedure, a 
technologist will take you into the CT scan room where you will lie down on the table (usually on 
your back) inside of the CT machine.  You should get comfortable because it is very important 
that you not move during certain parts of the test. 
CT examinations differ depending on the part of your body being studied.  For example, if your 
abdomen is being studied, a series of pictures will be taken from your lower chest to your lower 
pelvis.  During the study, you will be asked to hold your breath so that the pictures will not be 
blurred.  The machine will make some noise, and the table will move during the scan.  Also, you 
may receive signals from the technologist or from the machine about your breathing.  Before or 
during the study, you may be given an injection of a contrast liquid in your vein to allow the 
radiologist to obtain clearer images of your organs.  If you have any discomfort during the test or 
after the injection, be sure to tell the technologist. 
Confidentiality 
There is a risk of loss of confidentiality of your information.  You will read more about the 
protection of your information later in this form.  Please ask the study doctor or study staff if you 
would like to know more about how your information will be protected while you are in this study.
