Criteria

Inclusion Criteria MEI-401 Alone:

  • Diagnosis of relapsed/refractory CLL and/or relapsed/refractory SLL or FL
  • No prior therapy with PI3Kd inhibitors
  • No prior therapy with Bruton tyrosine kinase (BTK) inhibitors unless the subject was intolerant of BTK therapy or subject had disease progression
  • Subject must have failed at least 1 prior systemic therapy
  • QT-interval corrected according to Fridericia's formula (QTcF) ≤ 450 milliseconds (ms)
  • Left ventricular ejection fraction > 50%
  • For subjects, except those with CLL, must have at least one bi-dimensionally measurable nodal lesion >1.5 cm, as defined by Lugano Classification
  • Willingness to participate in collection of pharmacokinetic samples
  • A negative serum pregnancy test within 14 days of study Day 0, for females of childbearing potential

Inclusion Criteria ME-401 in Combination with Rituximab

  • Diagnosis of relapsed/refractory CLL SLL or FL, MZL, DLBCL and high-grade B-cell lymphoma. Subjects must meet the following criteria for relapsed or refractory disease:
  • No prior therapy with PI3Kδ inhibitors
  • No prior therapy with Bruton tyrosine kinase (BTK) inhibitors unless the subject was intolerant of BTK therapy or subject had disease progression
  • Subjects with CLL, SLL, FL, and MZL must have a failure of at least 1 prior systemic therapy and be considered by the investigator a candidate for therapy with a rituximab-based regimen; subjects with DLBCL and high-grade B-cell lymphoma must have a failure of at least 2 prior therapies.
  • QT-interval corrected according to Fridericia's formula (QTcF) ≤450 milliseconds (ms)
  • Left ventricular ejection fraction > 50%
  • For subjects, except those with CLL, must have at least one bi-dimensionally measurable nodal lesion >1.5 cm, as defined by Lugano Classification
  • Willingness to participate in collection of pharmacokinetic samples
  • A negative serum pregnancy test within 14 days of study Day 0 for females of childbearing potential

Inclusion Criteria ME-401 in Combination with Zanubrutinib

  • Diagnosis of relapsed/refractory CLL or histologically-confirmed relapsed/refractory SLL or FL, MZL, MCL, DLBCL NOS (germinal center B-cell type or activated B-cell type)
  • No prior therapy with PI3Kδ inhibitors
  • No prior therapy with BTK inhibitors
  • Subjects with CLL, SLL, FL, MCL, and MZL must have a failure of at least 1 prior systemic therapy, require treatment in the opinion of the investigator, and be considered by the investigator a candidate for therapy subjects with DLBCL and high-grade B-cell lymphoma must have a failure of at least 2 prior therapies
  • For subjects with SLL, FL, MZL, MCL, DLBCL: At least one bi dimensionally measurable nodal lesion > 1.5 cm in its longest diameter by CT scan or MRI
  • QT-interval corrected according to Fridericia's formula (QTcF) ≤ 450 milliseconds (msec)
  • Left ventricular ejection fraction > 50% as measured by echocardiogram or multigated acquisition (MUGA) scan
  • Willingness to participate in collection of pharmacokinetic samples
  • For females of childbearing potential, a negative serum pregnancy test within 14 days of study Day 0

Exclusion Criteria:

  • Known histological transformation from CLL to an aggressive lymphoma
  • Uncontrolled autoimmune hemolytic anemia or immune thrombocytopenia
  • Subjects who have tested positive for hepatitis B surface antigen and/or hepatitis B core antibody
  • Positive for hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus (HIV) antibody
  • Ongoing drug-induced pneumonitis
  • History of clinically significant cardiovascular abnormalities
  • History of severe bleeding disorders (ME-401 plus zanubrutinib arm only)
  • Known central nervous system (CNS) hemorrhage or stroke within 6 months prior to start of study drugs (ME-401 plus zanubrutinib arm only)
