Phase II Anti-PD1 Epigenetic Therapy Study in NSCLC.

Inclusion Criteria

• •Patients must have histologically proven stage IIIB, IV or recurrent non-small cell lung cancer. Patients must be willing to undergo a pre-treatment biopsy, either core needle biopsy or equivalent amount or via excisional specimen. (cytology specimen not acceptable for this purpose).
• •Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as \>20 mm with conventional techniques or as \>10 mm with spiral CT scan, MRI, or calipers by clinical exam. See Section 11 for the evaluation of measurable disease. A CT scan of the abdomen and pelvis is not required for patients with no disease in these areas.
• •Age \>18 years. Because no dosing or adverse event data are currently available on the use of azacitidine with entinostat, or of Nivolumab, in patients \<18 years of age, children are excluded from this study.
• •Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1.
• •Life expectancy of greater than 12 weeks.
• •Patients must have adequate organ and marrow function.
• •The effects of entinostat, azacitidine, and Nivolumab, on the developing human fetus are unknown. For this reason women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation and for up to 23 weeks after the last dose of nivolumab. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men who are sexually active with women of childbearing potential must also use an adequate contraceptive method for up to 31 weeks after fhe last dose of nivolumab.
• •Ability to understand and the willingness to sign a written informed consent document.
• •All adenocarcinoma patients must be tested for ALK rearrangements and EGFR (Exon 19 Deletion and Exon 21 L8585R Substitution) mutations and must have been treated with EGFR or ALK TKI therapy if found to have an actionable alteration. If patients are KRAS positive, testing for ALK rearrangements and EGFR mutations is not applicable.
• •All patients should have been offered a platinum-based chemotherapy. For EGFR/ALK wild type patients, no more than two prior chemotherapy-based lines of therapy for advanced or metastatic NSCLC is permitted. For EGFR mutated or ALK translocated patients, no more than three prior lines of therapy for advanced or metastatic NSCLC is permitted. Patients who refuse platinum based chemotherapy, may be allowed to enroll if they meet all other criteria.
• •* Patients who received adjuvant or neoadjuvant platinum-doublet chemotherapy (after surgery and/or radiation therapy) and developed recurrent or metastatic disease within 6 months of completing therapy are eligible and the adjuvant or neoadjuvant chemotherapy will count as a line of therapy as above.
• •* Subjects with recurrent disease \> 6 months after adjuvant or neoadjuvant platinum-based chemotherapy, who also subsequently progressed during or after a platinum-doublet regimen given to treat the recurrences, are eligible and do not count as another line of therapy for advanced disease.
• •* Subjects who received pemetrexed, bevacizumab, or erlotinib as maintenance therapy (nonprogressors with platinum-based doublet chemotherapy) and subsequently progressed after maintenance therapy, are eligible and do not count as a line of therapy. However, subject who received a tyrosine kinase inhibitor after failure of a prior platinum-based therapy, that tyrosine kinase inhibitor therapy would count as an additional line of therapy.
