Safety and Efficacy Study of CC-486 With MK-3475 to Treat Locally Advanced or Metastatic Non-small Cell Lung Cancer

Exclusion Criteria

• •1. Participants with non-squamous histology has known or unknown sensitizing epidermal growth factor receptor (EGFR) and/or anaplastic lymphoma kinase positive (ALK) mutation. Note: Participants with squamous histology and unknown EGFR and ALK mutational status are eligible.
• •2. Participant has received more than one line of therapy for stage IIIB or IV disease
• •3. Participant has been previously treated with azacitidine (any formulation), decitabine, or any other hypomethylating agent.
• •4. Particpant has received prior therapy with any other anti-PD-1, or PD-L1 or PD-L2 agent or an antibody targeting other immuno-regulatory receptors or mechanism, including participation in any other pembrolizumab trial and treatment with pembrolizumab.
• •a. Examples of such antibodies include (but are not limited to) antibodies against indoleamine 2,3-dioxygenase (IDO), PD-L1, IL-2R, glucocorticoid-induced tumor necrosis factor receptor (GITR).
• •5. Participant has had a prior monoclonal antibody within 4 weeks prior to study Day 1 or who has not recovered (i.e. ≤ Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.
• •6. Participant is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks prior to administration of pembrolizumab and CC-486
• •7. Participant has previous severe hypersensitivity reaction to another monoclonal antibody (mAb).
• •8. Participant has a known or suspected hypersensitivity to azacitidine, mannitol, or any other ingredient used in the manufacture of CC-486 (see the Azacitidine IB).
• •9. Participant has had radiotherapy ≤ 4 weeks or limited field radiation for palliation
• •10. Participant has received radiation therapy to the lung that is \> 30 Gy within 6 months of the first dose of trial treatment
• •11. Participant has received a live-virus vaccination within 30 days of planned treatment start. Seasonal flu vaccines that do not contain live virus are permitted.
• •12. Participant has not recovered from the acute toxic effects of prior anticancer therapy, radiation, or major surgery/significant trauma.
• •13. Participant has an active infection requiring therapy.
• •14. Participant has had an allogenetic tissue/solid organ ransplant.
• •15. Participant has active autoimmune disease that has required systemic treatment within the past 2 years (eg, with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
• •16. Participant has known active Hepatitis B, Hepatitis C or tuberculosis. Active Hepatitis B is defined as a known positive HBsAg result. Active Hepatitis C is defined by a known positive Hepatitis C antibody result and known quantitative Hepatitis C virus (HCV) ribonucleic acid (RNA) results greater than the lower limits of detection of the assay.
• •17. Participant has had any other malignancy within 5 years prior to randomization, with the exception of adequately treated in situ carcinoma of the cervix, uterus, or nonmelanomatous skin cancer (all treatment of which should have been completed 6 months prior to enrollment).
• •18. Participant has a history of inflammatory bowel disease (eg, Crohn's disease, ulcerative colitis), celiac disease (ie, sprue), prior gastrectomy or upper bowel removal, or any other gastrointestinal disorder or defect that would interfere with the absorption, distribution, metabolism, or excretion of the IP and/or predispose the participant to an increased risk of gastrointestinal toxicity.
• •19. Participant has persistent diarrhea or clinically significant malabsorption syndrome or known sub-acute bowel obstruction ≥ Grade 2, despite medical management
• •20. Participant has significant active cardiac disease within the previous 6 months including unstable angina or angina requiring surgical or medical intervention, significant cardiac arrhythmia, or New York Heart Association (NYHA) class 3 or 4 congestive heart failure.
• •21. Participant has history of interstitial lung disease (ILD) OR a history of pneumonitis that has required oral or IV steroids. Participants whose pneumonitis was solely as a result of radiation therapy for their NSCLC would not be excluded from the study unless they received oral/IV steroids to manage the pneumonitis.
• •22. Participant has a known history or current diagnosis of human immunodeficiency virus (HIV) infection, regardless of treatment status.
• •23. Participant has any other concurrent severe and/or uncontrolled medical condition that would, in the Investigator's judgment, contraindicate patient participation in the clinical study (eg, chronic pancreatitis, etc.).
• •24. Participant with uncontrolled or symptomatic central nervous system (CNS) metastases and/or carcinomatous meningitis Participants with controlled and asymptomatic CNS metastases may participate in this trial. The patient must have completed any prior treatment for CNS metastases (must include radiotherapy and/or surgery) ≥ 28 days (≥ 14 days for stereotactic radiosurgery) and, if on corticosteroid therapy, should be receiving a stable dose of no greater than 4 mg/d dexamethasone (or equivalent anti-inflammatory potency of another corticosteroid) for at least 14 days before start of study treatment). Patients must not be receiving corticosteroids for brain metastases.
• •25. Partcipant has not recovered from the acute toxic effects (Common Terminology Criteria for Adverse Events \[CTCAE\] grade ≤ 1) of prior anticancer therapy, radiation, or major surgery/significant trauma (except alopecia or other toxicities not considered a safety risk for the particiapants at the Investigator's discretion).
• •26. Participant has an impaired ability to swallow oral medication.
• •27. Participant is pregnant or breast feeding.
• •28. Participant has any condition that confounds the ability to interpret data from the study.
• •29. Participant is or has an immediate family member (spouse or children) who is investigational site or sponsor staff directly involved with this trial, unless prospective Institutional Review Board (IRB) approval (by chair or designee) is given allowing exception to this criterion for a specific participant.
