• A pretreatment biopsy of the primary site sufficient for immune studies is required.
• Age >/= 18 years
• ECOG PS 0-1

• Predicted life expectancy >/= 12 weeks
• Total bilirubin <2.5 x Upper limit of normal (ULN); AST (SGOT) < 2.5 x ULN; ALT (SGPT) < 2.5 x ULN; serum creatinine </= 1.5 x ULN (Gilbert's disease allowed with elevated bilirubin)
• Patients must be accessible for repeat dosing and follow-up
• Patients - both males and females - with reproductive potential must agree to practice effective contraceptive measures throughout the study. Women of childbearing potential must provide a negative pregnancy test at baseline and on Day 1
• Patients must provide verbal and written informed consent to participate in the study.
• A biopsy of the primary tumor or lymph node must be available for testing and immune evaluation

Exclusion criteria

• History of pneumonitis
• History of prior immunotherapy
• History of receiving PI3K inhibitors.
• Patients at 1.5mg or more a day of dexamethasone (or equivalent).
• History of significant cardiac disease unless the disease is well-controlled
