This is a multicenter, open-label, single-arm, phase II clinical trial to evaluate the
efficacy and safety of INCMGA00012 in Advanced Penile Squamous Cell Carcinoma
Men age ≥ 18 years with locally advanced unresectable or metastatic PSqCC stage 4 (i.e. T4 or
N3 or M1) that are presenting with radiologic progression of disease (PD) following or not
standard treatment with chemotherapy.
After signing the ICF and confirmed eligibility, patients will receive INCMGA00012 500 mg by
intravenous infusion on Day1 of each cycle, once every four weeks for up to 2 years.
Patients will receive treatment until disease progression, unacceptable toxicity, death, or
discontinuation from the study treatment for any other reason.
Patients discontinuing the study treatment period will enter a post-treatment follow-up
period during which survival and new anti-cancer therapy information will be collected every
3 months (± 14 days) from the last dose of investigational product until the end of study
(EoS).
Inclusion Criteria:
1. Patients have been informed about the nature of study, and have agreed to participate
in the study, and signed the informed consent form (ICF) prior to participation in any
study-related activities.
2. Male patients ≥ 18 years of age at the time of signing ICF.
3. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) 0-1.
4. Life expectancy ≥12 weeks.
5. Histologically-proven PSqCC.
6. Locally advanced unresectable or metastatic stage 4 PSqCC that is not amenable to
resection with curative intent (T4 or N3 or M1).
7. Radiological evidence of locally advanced or metastatic disease.
8. Patients must have measurable disease or evaluable disease according to Response
Evaluation Criteria in Solid Tumors (RECIST) version (v.)1.1 criteria.
9. Patients must agree to provide a tumor tissue sample from a metastatic site or the
primary tumor at the time of study entry, with the exception of patients whom tumor
biopsies cannot be obtained (e.g., inaccessible tumor or subject safety concern) that
may submit an archived tumor specimen only upon agreement from the Sponsor. If
feasible, patients will also be given the option of providing a tumor tissue sample at
disease progression from metastasis or primary tumor (if tumor biopsies cannot be
obtained for inaccessible lesion or subject safety concern).
10. Willingness and ability to provide blood samples (liquid biopsy) at the time of
inclusion, after 2 cycles of study treatment (C3D1), and upon PD or study termination.

count (ANC) ≥ 1.5 x 109/L, platelet count ≥ 75.0 x109/L, and hemoglobin > 9.0
g/dL.
2. Hepatic: Bilirubin ≤ 1.5 times the upper limit of normal (× ULN) (< 3 x ULN in
the case of Gilbert's disease); aspartate transaminase (AST), and alanine
transaminase (ALT) ≤ 2.5 times × ULN (in the case of liver metastases ≤ 5 × ULN);
Albumin > 2.5 mg/mL.
3. Renal: Serum creatinine ≤ 1.5 x ULN; alternately measured or calculated
creatinine clearance ≥30 mL/min with creatinine levels >1.5 × institutional ULN
(glomerular filtration rate [GFR] can also be used in place of creatinine or
creatinine clearance).
4. Coagulation: Activated Partial Thromboplastin Time (aPTT) ≤1.5 X ULN and
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.
12. Patients who are willing and able to comply with scheduled visits, treatment plan,
laboratory tests, and other study procedures.
13. Subjects should agree to use an adequate method of contraception starting with the
first dose of study therapy through 180 days after the last dose of study treatment.
14. Patients that have received prior chemotherapy regimens or radiotherapy for locally
recurrent and/or metastatic disease are not excluded but patients naïve of systemic
treatment can also be included.
15. For pretreated patients, last dose of chemotherapy administered ≥ 28 days from study
entry.
Exclusion criteria
1. Locally PSqCC candidate for curative treatment.
2. Prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.
3. Known hypersensitivity to any of the excipients of INCMGA00012.
4. Receipt of anticancer therapy or participation in another interventional clinical
study within 28 days before the first administration of study drug; 6 weeks for
mitomycin C.
5. Radiotherapy within 14 days of first dose of study treatment with the following
caveat: 28 days for pelvic radiotherapy.
6. Toxicity of prior therapy that has not recovered to ≤ Grade 1 or baseline (with the
exception of any grade of alopecia and anemia not requiring transfusion support).
Endocrinopathy, if well-managed, is not exclusionary and should be discussed with
Sponsor's medical monitor.
7. Major surgery (defined as requiring general anesthesia) or significant traumatic
injury within 4 weeks of start of study drug, or patients who have not recovered from
the side effects of any major surgery, or patients who may require major surgery
during the study.
8. Known active uncontrolled or symptomatic Central Nervous System (CNS) metastases,
carcinomatous meningitis, or leptomeningeal disease as indicated by clinical symptoms,
cerebral edema, and/or progressive growth. Patients with a history of CNS metastases
or cord compression are eligible if they have been definitively treated (e.g.,
radiotherapy, stereotactic surgery) and are clinically stable off anticonvulsants and
steroids for at least 4 weeks before randomization.

etc.) is not considered a form of systemic treatment.
