Patients with relapsed or refractory NHL for whom:

1. Standard of care treatment options no longer exist (Stage 1 only);
2. Standard of care treatment options no longer exist with the exception of PI3K-delta inhibitors (Stage 2 only);
3. Expected survival of more than 24 weeks.

Exclusion Criteria:

Patients who meet any of the following criteria will be excluded from study entry:

1. Primary central nervous system (CNS) lymphoma;
2. Any of the following laboratory abnormalities Absolute neutrophil count; <1.0×10^9/L, Hemoglobin <80 g/L Platelets <50 ×10^9/L

Inadequate organ function, defined by the following:

1. Total bilirubin ≥1.5 times the upper limit of normal (× ULN);
2. AST or ALT > 2.5 × ULN;
3. Estimated creatinine clearance (CrCl) per Cockcroft-Gault;
4. Dose Escalation stage of trial (Stage 1) - CrCl < 40 mL/min;
5. Dose Expansion stage of trial (Stage 2) - CrCl <30 mL/min;
6. International normalized ratio (INR) > 1.5 × ULN, activated partial thromboplastin time (aPTT) > 1.5 × ULN;
7. Serum amylase or lipase > ULN at screening or known medical history of serum amylase or lipase > ULN;
8. Patients with presence of second primary malignant tumors within the last 2 years;
9. Clinically significant history of liver disease;
10. Prior treatment with any PI3Kδ inhibitors;
11. Any prior use of the following: cancer therapy within 3 weeks of study treatment, GCSF within 7 days of screening, steroid therapy or targeted anti-neoplastic intent within 7 days of treatment, any use of strong CYP3A4 inducers within 2 weeks prior to initiation of study treatment, prior autologous transplant within 6 months of study treatment, prior allogenic stem cell transplant within 6 months of study treatment;
12. Clinically significant active infection or interstitial lung diseases (including drug induced pneumonitis);
13. Major surgical procedure within 4 weeks prior to initiation of study treatment;
14. Adverse events from prior anti-neoplastic therapy that have not resolved to Grade less than or equal to 1, except for alopecia;
15. New York Heart Association (NYHA) Class II or greater congestive heart failure;
16. Congenital long QT syndrome or QTc >470 msec;
17. Currently use medication known to cause QT prolongation or torsades de pointes;
18. History of myocardial infarction or unstable angina within 6 months prior to initiation of study treatment;
19. History of stroke or transient ischemic attack within 6 months prior to initiation of study treatment;
20. Inability to take oral medication, prior surgical procedures affecting absorption, or active peptic ulcer disease;
21. History of inflammatory bowel disease (e.g., Crohn's disease or ulcerative colitis);
22. Patients with ongoing chronic gastrointestinal diseases;
23. Any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding that, in the investigator's opinion, gives reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that may affect the interpretation of the results or renders the patient at high risk from treatment complications.
