Patients can currently be on a checkpoint inhibitor or HDAC inhibitor, including one of the study drugs, at time of screening.
• Patient has at least one site of measurable disease (≥ 1.5 cm), which may be lymph node or extranodal lesion, which is seen on screening imaging studies within 28 days of start of study drug

  • Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 1.5 x ULN (or

    ≤3 x ULN if liver involved with disease

  • Total serum bilirubin or plasma bilirubin ≤ 1.5 x ULN ( ≤ 3 x ULN with direct bilirubin within normal range in patients with documented hepatic involvement, well documented Gilbert"s Syndrome)
  • International Normalized Ratio (INR) or Prothrombin
  • Time (PT) ≤1.5×ULN unless patient 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×ULN unless patient is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
  • Patients with GFR>45 ml/min. Patients with GFR 45-59 ml/min are eligible but will undergo dose adjustments as specified in section 9.0.1
• Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
• Female subjects of childbearing potential must be willing to use an adequate method of contraception. Subjects must adhere to the contraception requirement from the day of study medication initiation, (or 14 days prior to the initiation of study medication for oral contraception) throughout the entire study, and up 120 days after the last dose of trial therapy.

Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.

• Male subjects of childbearing potential (Section 9.8.2) must agree to use an adequate method of contraception as outlined in Section 9.8.2- Subjects must adhere to the contraception requirement from the day of study medication initiation, (or 14 days prior to the initiation of study medication for oral contraception) throughout the entire study, and up 120 days after the last dose of trial therapy.

Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.

Exclusion Criteria:

• Diagnosed or treated for malignancy other than the indication under study except for

  • Malignancy treated with curative intent and with no known active disease present for at least 2 years before the first dose of study treatment
  • Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
  • Adequately treated cervical carcinoma in situ without evidence of disease
• History of Human Immunodeficiency Virus (HIV)
• Active Hepatitis B or C infection
• History of active TB (Bacillus Tuberculosis)
• Concurrent enrollment in another therapeutic investigational clinical study 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 study drug
• Known CNS lymphoma involvement
• Any uncontrolled active systemic infection or any life-threatening illness, medical condition, or organ system dysfunction which, in the investigator"s opinion, could compromise the subject"s safety, interfere with the absorption or metabolism of entinostat capsules, or put the study outcomes at undue risk.
• Any history of (non-infectious) pneumonitis that required steroids, evidence of interstitial lung disease or active, non- infectious pneumonitis
• Myocardial infarction or arterial thromboembolic events within 6 months prior to baseline or severe or unstable angina, New York Heart Association (NYHA) Class III or IV disease, or a QTc interval > 470 msec.
• History of Torsades de pointes, ventricular tachycardia, or ventricular fibrillation within 6 months prior to screening

• Any active autoimmune disease or a documented history of autoimmune disease (excluded/exception to the rule: subjects with vitiligo or resolved childhood asthma/atopy, type I diabetes mellitus, subjects with hypothyroidisms stable on hormone replacement, Sjorgen"s syndrome, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger).
• Any syndrome that requires ongoing systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 7 days of study drug administration. Of note: Inhaled or topical steroids, and adrenal replacement doses are permitted
• Women who are pregnant or breast feeding
• Has received a live vaccine or live-attenuated vaccine within 30 days of planned start of study therapy. Administration of killed vaccines is allowed. 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
