Phase II Trial of Pembrolizumab for Advanced Penile Squamous Cell Carcinoma Following Previous Chemotherapy

Penile squamous cell carcinoma (PSCC) is relatively rare but exhibits higher incidences in
less developed countries. PSCC is a highly aggressive malignancy characterized by early
spread. Pembrolizumab has recently been FDA-approved for the treatment of melanoma but will
serve as the investigational agent for this penile cancer study.

This is a multicenter trial to evaluate Pembrolizumab for patients with advanced penile
squamous cell carcinoma following prior chemotherapy. Participating institutions are the
University of Alabama at Birmingham (coordinating center), M.D. Anderson Cancer Center,
University of Michigan, University of Minnesota, and Emory University. Patients will receive
intravenous Pembrolizumab every 3 weeks and undergo a clinical exam. Radiographic scans will
be done at baseline and every 9 weeks. Therapy will continue until disease progression or
there are intolerable toxicities.

Inclusion Criteria:

1. Locally advanced unresectable or metastatic stage 4 (i.e. T4 or N3 or M1) PSCC

2. Radiologic evidence for progressive disease after ≥1 prior chemotherapy regimen

3. Be at least 18 years of age on day of signing informed consent.

4. Have measurable disease based on RECIST 1.1.

5. Have a performance status of 0-2 on the ECOG (Eastern Cooperative Oncology Group)
Performance Scale.

6. Demonstrate adequate organ function with all screening labs being performed within 14
days of treatment initiation.

- Absolute neutrophil count (ANC) ≥1,500 /mcL

- Platelets ≥100,000/mcL

- Hemoglobin ≥9 g/dL or ≥5.6 mmol/L without transfusion or erythropoietin
dependency (within 7 days of assessment)

- Serum creatinine ≤1.5 X upper limit of normal (ULN); alternately measured or
calculated creatinine clearance ≥30 mL/min with creatinine levels >1.5 X
institutional ULN (GFR can also be used in place of creatinine or CrCl)

- Serum total bilirubin ≤1.5 X ULN or direct bilirubin ≤ ULN for subjects with
total bilirubin levels >1.5 ULN

- AST (SGOT) and ALT (SGPT) ≤ 2.5 X ULN or ≤ 5 X ULN for subjects with liver
metastases

- Albumin >2.5 mg/dL

- International Normalized Ratio (INR) or Prothrombin Time (PT) ≤1.5 X ULN unless
subject is receiving anticoagulant therapy as long as PT or PTT is within
therapeutic range of intended use of anticoagulants

- Activated Partial Thromboplastin Time (aPTT) ≤1.5 X ULN unless subject is
receiving anticoagulant therapy as long as PT or PTT is within therapeutic range
of intended use of anticoagulants

7. Subjects should agree to use an adequate method of contraception starting with the
first dose of study therapy through 120 days after the last dose of study therapy

8. Formalin-fixed paraffin embedded (FFPE) tumor tissue from previous biopsy is
requested, but not mandatory.

9. Be willing and able to provide written informed consent/assent for the trial.

Exclusion Criteria:

1. Is currently participating and receiving study therapy or has participated in a study
of an investigational agent and received study therapy or used an investigational
device within 4 weeks of the first dose of treatment.

2. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any
other form of immunosuppressive therapy within 7 days prior to the first dose of trial
treatment.

3. Has a known history of active TB (Bacillus Tuberculosis)

4. Hypersensitivity to Pembrolizumab or any of its excipients.

5. Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study
Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events
due to agents administered more than 4 weeks earlier.

6. Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy
within 2 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at
baseline) from adverse events due to a previously administered agent.

- Note: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and
may qualify for the study.

- Note: If subject received major surgery, they must have recovered adequately from
the toxicity and/or complications from the intervention prior to starting
therapy.

7. Has a known additional malignancy that is progressing or requires active treatment.
Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the
skin that has undergone potentially curative therapy or in situ cervical cancer.

8. Has known active central nervous system (CNS) metastases and/or carcinomatous
meningitis. Subjects with previously treated brain metastases may participate provided
they are stable (without evidence of progression by imaging for at least four weeks
prior to the first dose of trial treatment and any neurologic symptoms have returned
to baseline), have no evidence of new or enlarging brain metastases, and are not using
steroids for at least 7 days prior to trial treatment. This exception does not include
carcinomatous meningitis which is excluded regardless of clinical stability.

9. Has active autoimmune disease that has required systemic treatment in the past 2 years
(i.e. with use of disease modifying agents, corticosteroids or immunosuppressive
drugs). Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid
replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a
form of systemic treatment.

10. Has known history of, or any evidence of active, non-infectious pneumonitis.

11. Has an active infection requiring systemic therapy.

12. Has a history or current evidence of any condition, therapy, or laboratory abnormality
that might confound the results of the trial, interfere with the subject's
participation for the full duration of the trial, or is not in the best interest of
the subject to participate, in the opinion of the treating investigator.

13. Has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial.

14. Is pregnant expecting to father children within the projected duration of the trial,
starting with the pre-screening or screening visit through 120 days after the last
dose of trial treatment.

15. Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.

16. Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies).

17. Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA
[qualitative] is detected).

18. Has known active Tuberculosis infection.

19. Has received a live vaccine within 30 days of planned start of study therapy. Note:
Seasonal influenza vaccines for injection are generally inactivated flu vaccines and
are allowed; however intranasal influenza vaccines (e.g., Flu-Mist®) are live
attenuated vaccines, and are not allowed.
