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.
9. Cardiovascular: patients that have any of the following within 6 months of
randomization: severe/unstable angina, myocardial infarction, symptomatic
pericarditis, symptomatic congestive heart failure (New York Heart Association
functional classification III-IV), cerebrovascular accident including transient
ischemic attack, or symptomatic pulmonary embolism, coronary/peripheral artery bypass
graft, ongoing cardiac dysrhythmias of National Cancer Institute-Common Terminology
Criteria for Adverse Events (NCI-CTCAE) v.5.0 grade =2, including, ventricular
arrhythmias -except for benign premature ventricular contractions-, supraventricular
and nodal arrhythmias requiring a pacemaker or not controlled with medication, any
conduction abnormality requiring a pacemaker or any cardiac arrhythmia not controlled
with medication.
10. Metabolic: Uncontrolled hyper/hypothyroidism or diabetes mellitus type 1 (T1DM).
Patients with hypothyroidism stable on hormone replacement will not be excluded from
the trial. Patients with controlled T1DM on a stable insulin regimen may be eligible
for this study.
11. Diagnosis of immunodeficiency or is receiving systemic steroid therapy or
immunosuppressive therapy within seven days prior to study treatment initiation.
12. Active autoimmune disease that has required systemic treatment in past 2 years (i.e.,
with use of disease modifying agents, corticosteroids, or immunosuppressive drugs).
Note: Replacement therapy (e.g., thyroxine, insulin, or physiologic steroid
replacement therapy (= 10 mg prednisone daily) for adrenal or pituitary insufficiency,
etc.) is not considered a form of systemic treatment.
13. Prior allogenic stem cell or solid organ transplantation.
14. Has received a live vaccine within 28 days of the planned start of study drug. Note:
Examples of live vaccines include, but are not limited to, the following: measles,
mumps, rubella, chicken pox/zoster, yellow fever, rabies, Bacillus Calmette-Guérin
(BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally
killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g.,
FluMist®) are live-attenuated vaccines and are not allowed.
15. Active/history of pneumonitis requiring treatment with steroids or active/history of
interstitial lung disease.
16. Active uncontrolled infection at the time of screening.
17. Latent tuberculosis determined by a positive TST followed by confirmation by

18. Participants who are known to be human immunodeficiency virus (HIV)-positive, unless
all of the following criteria are met:
1. CD4-positive count = 300/µL;
2. Undetectable viral load;
3. Receiving highly active antiretroviral therapy.
19. Active hepatitis A virus (HAV) (positivity for HAV IgM antibody), hepatitis B virus
(HBV) (patients with negative hepatitis B surface antigen [HBsAg] test and a positive
antibody to HBsAg [anti-HBsAg] test at screening are eligible) or hepatitis C virus
(HCV) (patients with a positive antibody to hepatitis C [anti-HCV] are eligible only
if polymerase chain reaction [PCR] is negative for virus hepatitis C ribonucleic acid
[RNA]).
