Inclusion Criteria

  • 1. Signed informed consent.
  • 2. Age =18 years (or age of majority).
  • 3. Histologically confirmed diagnosis as defined in the World Health
  • Organization (WHO) classification (Swerdlow 2016) of:
  • a. Follicular lymphoma (FL) limited to Grade 1, 2, or 3a; or
  • b. Marginal zone lymphoma (MZL), including nodal, extranodal, and
  • splenic MZL (histopathological report confirming diagnosis must be
  • available during screening procedures).
  • 4. Subjects with relapsed or refractory FL or MZL who received =2 prior therapy regimens. A previous regimen is defined as one of the following:
  • at least two months of single-agent therapy or at least two consecutive cycles of polychemotherapy, autologous transplant, or
  • radioimmunotherapy. Prior therapy must include an anti-CD20
  • monoclonal antibody (mAb) and an alkylating agent(s). Relapsed or
  • refractory disease is defined as:
  • a. Relapsed disease: disease progression after a response (CR or PR)
  • lasting = 6 months
  • b. Refractory disease: no response to therapy (no CR or PR), or response lasting <6 months
  • 5. At least one bi-dimensionally measurable nodal lesion >1.5 cm or
  • extranodal lesions >1 cm in its longest diameter by computed
  • tomography (CT) scan as defined by the Modified Lugano
  • Classification(Appendix 5).
  • a. Previously irradiated lesions can be selected as target lesions only in cases of unequivocal evidence of progression.
  • b. For subjects with splenic MZL only: diffuse spleen involvement with splenomegaly, which is defined as the splenic vertical length greater than 13 cm.
  • 6. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 (Oken 1982; Appendix 6).
  • 7. Adequate hematologic parameters at screening unless abnormal
  • values are due to lymphoma per Investigator assessment:
  • a. Absolute neutrophil count (ANC) =1.0 × 109/L (= 1,000/mm3)
  • b. Platelet count =75.0 × 109/L (= 75,000/mm3)
  • 8. Adequate renal and hepatic function per local laboratory reference
  • range at screening as follows:
  • a. Aspartate aminotransferase (AST)/serum glutamic-oxaloacetic
  • transaminase (SGOT), alanine aminotransferase (ALT)/serum glutamicpyruvate transaminase (SGPT) =3.0 × upper limit of normal(ULN)
  • b. Total bilirubin =2.0 × ULN or =3 × ULN for subjects with Gilbert's
  • c. Serum creatinine =1.5 × ULN or estimated glomerular filtration rate
  • (eGFR) >50 mL/min using the Cockcroft-Gault equation (Appendix 2)
  • 9. QT-interval corrected according to Fridericia's formula (QTcF) =450
  • milliseconds (msec); subjects with QTc >450 msec but <480 msec may
  • be enrolled provided the QTc prolongation is due to a right bundle
  • branch block (RBBB), left bundle branch block (LBBB), or pacemaker and is confirmed stable by a cardiologist.
  • 10. Left ventricular ejection fraction (LVEF) = 45% as measured by
  • echocardiogram or multigated acquisition scan (MUGA). If LVEF <45%
  • by ECHO, a repeat measurement can be conducted within the screening period.
  • 11. Subjects must have completed any prior systemic anti-cancer
  • treatment within =4 weeks of Cycle 1 Day 1 (or =5 times the half-life
  • [t½], whichever is longer); =8 weeks for antibody agents; =2 weeks for radiation therapy; and =3 months for high dose therapy with stem cell transplantation or CAR T cell therapy or radioimmunotherapy.
  • 12. All adverse events and laboratory toxicities related to prior therapy must resolve to Grade =1 prior to the start of the study therapy (unless otherwise specified in eligibility criteria).
  • 13. For females of childbearing potential, a negative serum human
  • chorionic gonadotropin

Exclusion Criteria

  • 1. Histologically confirmed FL Grade 3b, or transformed disease
  • (assessed by the Investigator):
  • a. For patients with clinical (e.g., marked B-symptoms), laboratory (e.g., high lactate dehydrogenase [LDH]) or radiographic (e.g., high
  • standardized uptake value by positron emission tomography [PET])
  • signs of rapid disease progression, a fresh tumor biopsy prior to
  • enrollment is required to rule out transformed disease
  • 2. Known lymphomatous involvement of the central nervous system.
  • 3. Major surgical procedure within 4 weeks prior to study Day 1 (minor surgical procedures, [e.g., lymph node biopsy] performed within 1 day or with an overnight stay are allowed).
  • 4. Prior therapy with PI3K inhibitors.
  • 5. Any uncontrolled clinically significant illness including, but not limited to, active infections requiring systemic antimicrobial therapy,
  • hypertension, angina, arrhythmias, pulmonary disease, or autoimmune dysfunction.
  • 6. Subjects who have tested positive for hepatitis B surface antigen
  • and/or hepatitis B core antibody plus have a positive hepatitis B
  • polymerase chain reaction (PCR) assay; subjects who have previously
  • tested positive with a negative PCR assay are permitted with appropriate anti-viral prophylaxis.
  • 7. Positive hepatitis C virus antibody (HCV Ab); subjects with positive
  • HCV Ab are eligible if they are negative for HCV by PCR.
  • 8. Known history of, or active human immunodeficiency virus (HIV)
  • 9. Ongoing or history of drug-induced pneumonitis.
  • 10. Previous or concurrent cancer that is distinct in primary site or
  • histology from indolent B-cell NHL within 3 years before start of study
  • treatment except for curatively treated cervical cancer in situ, nonmelanoma skin cancer, superficial bladder tumors (Ta [non-invasive tumor], Tis [carcinoma in situ], and T1 [tumor invades lamina propria]), and asymptomatic localized prostate cancer with no requirement for systemic therapy (or requiring only hormonal therapy) and with normal prostate-specific antigen values within =12 months prior to enrollment.
  • 11. History of clinically significant cardiovascular abnormalities such as congestive heart failure (New York Heart Association classification = II [NYHA 1994]), myocardial infarction within 6 months of study entry.
  • 12. History of clinically significant gastrointestinal (GI) conditions,
  • particularly:
  • a. Known GI condition that would interfere with swallowing or the oral absorption or tolerance of study drug
  • b. Pre-existing malabsorption syndrome or other clinical situation that would affect oral absorption
  • 13. Females who are pregnant; females who plan to breastfeed during study treatment through 90 days after ending treatment.
  • 14. Psychiatric illness/social situations that would interfere with study
  • compliance.
  • 15. Hypersensitivity or other clinically significant reaction to the study drug or its inactive ingredients.
  • 16. Any other condition for which, in the opinion of the Investigator,
  • participation would not be in the best interest of the subject.
