to registration and the subject must have recovered from all reversible acute toxic
effects of the regimen (other than alopecia or neuropathy) to =Grade 1 or baseline. If
subject underwent major surgery or radiation therapy of >30 Gy, they must have

to be obtained within 28 days prior to registration

- Hemoglobin (Hgb) =9 g/dL or =5.6 mmol/L
- Creatinine OR Measured or calculated creatinine clearance (CrCl) (glomerular
filtration rate [GFR] can also be used in place of CrCl) Creatinine clearance
should be calculated per institutional standard =1.5 x the upper limit of normal
(ULN) OR =60 mL/min for subject with creatinine levels >1.5 x institutional ULN
- Bilirubin =1.5 x ULN OR Direct bilirubin = ULN for subjects with total bilirubin
levels > 1.5 x ULN

- Alanine aminotransferase (ALT) =3 x ULN
- International Normalized Ratio (INR) or Prothrombin Time (PT) Activated Partial
Thromboplastin Time (aPTT) = 1.5 × ULN unless subject is receiving anticoagulant
therapy as long as PT/INR/PTT is within therapeutic range of intended use of
anticoagulants
- Women of childbearing potential (WOCBP) must have a negative serum pregnancy test
during screening and a negative urine pregnancy test within 3 days prior to first dose
of study drug. If the screening serum test is done within 3 days prior to receiving
the first dose of study drug, a urine test is not required.
- Women of childbearing potential must be willing to abstain from heterosexual
intercourse or to use an effective method of contraception from the time of informed
consent until 5 months after the last dose of study drug.
- Men who are sexually active with WOCBP must use any contraceptive method with a
failure rate of less than 1% per year. Men receiving study drugs and who are sexually
active with WOCBP will be instructed to adhere to contraception for a period of 3
months after the last dose of entinostat.
- As determined by the enrolling physician or protocol designee, ability of the subject
to understand and comply with study procedures for the entire length of the study.
- Life expectancy of at least 6 months per investigator discretion.
Exclusion Criteria:
- Subjects meeting any of the criteria below may not participate in the study:
- History or current evidence of any condition, therapy, or laboratory abnormality
that might confound the results of the study, interfere with the subject's
participation for the full duration of the study, or is not in the best interest
of the subject to participate, in the opinion of the treating investigator,
including, but not limited to:
- Myocardial infarction or arterial thromboembolic events within 6 months
prior to screening or severe or unstable angina, New York Heart Association
(NYHA) Class III or IV disease, or a corrected QT interval (QTc) interval >
470 msec.
- Uncontrolled hypertension or diabetes mellitus.
- Another known malignancy that is progressing or requires active treatment.
- Any prior history of other cancer within the prior 5 years with the
exception of adequately treated basal cell carcinoma or cervical
intraepithelial neoplasia [CIN]/cervical carcinoma in situ or melanoma in
situ).
- Active infection requiring systemic therapy.
- Known active central nervous system (CNS) metastases and/or carcinomatous
meningitis.
- Pregnant or breastfeeding. Note: breast milk cannot be stored for future use
while the mother is being treated on study.
- Any contraindication to oral agents or significant nausea and vomiting,
malabsorption, or significant small bowel resection that, in the opinion of the
investigator, would preclude adequate absorption.
- Allergy to benzamide or inactive components of entinostat.
- Hypersensitivity to nivolumab, ipilimumab, or any of their excipients.
- Treatment with any investigational drug or device within 4 weeks prior to
registration.
- Treatment with systemic steroids within 4 weeks prior to registration. Note:
adrenal replacement doses of steroids (for example prednisone 10mg daily) are
permitted while on study.
- Evidence of active autoimmune disease requiring systemic treatment within the
past 90 days or a documented history of clinically severe autoimmune disease, or
a syndrome that requires systemic steroids or immunosuppressive agents. Subjects
with vitiligo or resolved childhood asthma/atopy would be an exception to this
rule. Subjects that require intermittent use of bronchodilators or local steroid
injections would not be excluded from the study. Subjects with hypothyroidism
stable on hormone replacement or Sjogren's syndrome will not be excluded from the
study.
- Interstitial lung disease or history of pneumonitis requiring treatment with
corticosteroids.
- Diagnosis of immunodeficiency; or is receiving chronic systemic corticosteroid
therapy or other immunosuppressive therapy (excludes inhaled corticosteroids)
within 4 weeks prior to registration.
- Known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies). Testing
during screening is not required.
- Known active hepatitis B (e.g., hepatitis B surface antigen-reactive) or
hepatitis C (e.g., hepatitis C virus ribonucleic acid [qualitative]). Subjects
with past hepatitis B virus (HBV) infection or resolved HBV infection (defined as
the presence of hepatitis B core antibody [HBc Ab] and absence of HBsAg) are
eligible. HBV DNA test must be performed in these subjects prior to study
treatment, and results must be negative to be eligible. Subjects with a history
of hepatitis C must be tested for presence of hepatitis C virus (HCV) antibody.
If HCV antibody positive, subjects will only be eligible if polymerase chain
reaction is negative for HCV RNA.
- Has received a live vaccine within 30 days prior to planned start of study
therapy. Note: Seasonal influenza vaccines for injection are generally
