1. Male or female subjects =18 years of age, =19 years in Korea, or =20 years for subjects in Japan and Taiwan, at time of signing informed consent
2. Histologically confirmed diagnosis of CD20 positive iNHL with histological subtype limited to:
a. FL Gr 1, Gr 2, or Gr 3a
b. MZL (splenic, nodal, or extra-nodal)
[Histopathological report confirming diagnosis must be available during screening procedures]
3. Subjects with relapsed or refractory disease who received =1 prior lines of therapy that must have included an anti-CD20 antibody in combination with cytotoxic chemotherapy or L, with or without subsequent maintenance therapy. [A line of therapy is defined as following: a minimum of 2 consecutive cycles of immunochemotherapy or R-L, at least 4 doses of anti-CD20 mAb (R) single agent therapy a minimum of 2 consecutive cycles of therapy with an investigational agent. Maintenance therapy given after an induction treatment (e.g., R maintenance) is considered as the same line of therapy]. [Please seeExclusion Criteria #2 for further clarification]. Relapsed or refractory disease defined as:
• Relapsed disease: disease progression after a response (complete response [CR] or partial response [PR]) lasting =6 months
• Refractory disease: no response to therapy (no CR or PR) or response lasting <6 months
4. Subjects must have at least one bi-dimensionally measurable lesion >1.5 cm (that has not been previously irradiated) according to the Lugano Classification
5. Adequate hematologic parameters at screening unless abnormal values are due to disease per Investigator assessment:
• Absolute neutrophil count (ANC) =1.0 × 109/L (=1,000/mm3)
• Platelet count =75.0 × 109/L (=75,000/mm3)
• Hemoglobin =9 g/dL
6. Adequate renal and hepatic function per local laboratory reference range at screening as follows:
• Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =1.5 × upper limit of normal (ULN)
• Total bilirubin =2.0 × ULN or =3 × ULN for subjects with Gilbert-Meulengracht syndrome
• Estimated glomerular filtration rate (eGFR) >50 mL/min using the Cockcroft-Gault equation (Appendix 2)
7. QT-interval corrected according to Fridericia’s formula (QTcF) =450 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.
8. Left ventricular ejection fraction (LVEF) =45% as measured by echocardiogram (ECHO) or multi-gated acquisition scan. [If LVEF <45% by ECHO, a repeat measurement can be conducted within the screening period.]
9. Subjects must have completed any prior systemic anti-cancer treatment =4 weeks (or =5 times the half-life [t½] of used therapeutics [including investigational therapy], whichever is longer) or radiation therapy =2 weeks before study D1, and =3 months before study D1 for high dose therapy with stem cell transplantation, radioimmunotherapy, and CAR T-cell therapy.
10. Eastern Cooperative Oncology Group (ECOG) performance status 0-1
11. Life expectancy of at least 3 months
12. All AEs and laboratory toxicities related to prior therapy must resolve to Gr =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 (hCG) pregnancy test within 28 days of study D1 and negative hCG result on study D1
14. Subjects mu
1. Histologically confirmed diagnosis of FL Gr 3b or transformed disease
• For subjects with clinical signs of rapid disease progression (e.g., marked B-symptoms), and laboratory or radiographic indication (e.g., high lactate dehydrogenase level or standardized uptake value by PET), a fresh biopsy is recommended to rule out transformed disease
2. Subjects who received both R/O-B and R/O-CHOP (or other anthracycline-containing regimen) as previous lines of therapy, and those who received only single agent anti-CD20 mAb therapy as prior line of treatment
3. Prior therapy with PI3K inhibitors
4. Ongoing or history of drug-induced pneumonitis
5. Known lymphomatous involvement of the central nervous system
6. Seropositive for or active viral infection with hepatitis B virus:
• HBsAg positive
• HBsAg negative, anti-HBs positive and/or anti-HBc positive and detectable viral DNA by PCR
[Note: Subjects who are HBsAg negative and viral DNA PCR negative are eligible. These subjects should receive prophylactic therapy for hepatitis as per institutional standards.]
7. Known seropositive for, or active infection with hepatitis C virus.
• Subjects with positive hepatitis C virus (HCV) antibodies are eligible with negative PCR test for HCV
8. Known seropositive for, or active infection with human immunodeficiency virus
9. Known seropositive for, or active infection with human T-cell leukemia virus type 1
10. Any uncontrolled clinically significant illness including, but not limited to, active infections requiring systemic antimicrobial therapy, hypertension, angina, arrhythmias, pulmonary disease, or autoimmune dysfunction
11. Hypersensitivity or other clinically significant reaction to the study drug or its inactive ingredients
12. Major surgical procedure within 4 weeks prior to study D1 (minor surgical procedures, e.g., lymph node biopsy, performed within 1 day or with an overnight stay are allowed)
13. 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, non-melanoma skin cancer, and 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 randomization
14. History of clinically significant cardiovascular abnormalities such as congestive heart failure (New York Heart Association (NYHA) classification = II
[NYHA 1994]), myocardial infarction within 6 months of study entry.
15. History of clinically significant gastrointestinal (GI) conditions, particularly:
• Known GI condition that would interfere with swallowing or the oral absorption or tolerance of study drug
• Pre-existing malabsorption syndrome or other clinical situation that would affect oral absorption
16. Females who are pregnant; females who plan to breastfeed during study treatment through 90 days after ending treatment
17. Substance abuse, medical, psychological or social conditions that may interfere with the subject’s participation in the study or evaluation of the study results.
18. Any illness or medical conditions that are unstable or could jeopardize the safety of the subjects and their compliance in the study. Inability to understand and sign informed cons
