Exclusion Criteria:
  1. - Richter's syndrome, Burkitt's lymphoma, or Burkitt-like Lymphoma (transformed DLBCL from follicular NHL are eligible) - Prior transplant with stem cell infusion within 90 days of Day 1 or active graft-versus-host treatment within 8 weeks of Day 1 - Prior therapy with Spleen Tyrosine Kinase (SYK) inhibitors - Chronic treatment with strong CYP3A4 inhibitor/inducer - Known lymphomatous involvement of the central nervous system (CNS) - Persistent, unresolved National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Events (CTCAE) version 5.0 ≥Grade 2, previous drug-related toxicity (except alopecia, erectile impotence, hot flashes, libido, neuropathy). - Prior monoclonal antibody (including alemtuzumab), radioimmunoconjugate, antibody drug conjugate, phototherapy, radiotherapy, chemotherapy, immunotherapy, immunosuppressive therapy, or any test agent within 3 weeks of Day 1 - For CTCL: (total skin electron beam therapy [TSEBT]) within 12 weeks, or initiation of topical steroid, nitrogen mustard, or topical retinoid within 2 weeks. Stable topical regimen for ≥4 weeks prior to Day 1 allowed. - Known carrier or infection for human immunodeficiency virus (HIV)/hepatitis B or C. If hepatitis C virus (HCV) antibody (ab)+, must be polymerase chain reaction (PCR)- to be eligible. If hepatitis B virus (HBV) ab+, must be hepatitis B surface antigen (HBsAg)- or undetectable HBV deoxyribonucleic acid (DNA) to be eligible. - Active infection requiring systemic treatment, - Significant gastrointestinal (GI) disease, previous major gastric/bowel surgery, difficulty swallowing, or malabsorption syndrome - Major surgery within 4 weeks - Previous malignancies within 2 years unless relapse risk is small (<5%). - Current use of systemic steroids >20 mg QD prednisone (or equivalent) - Breastfeeding or pregnant (intention to become) females or participation in other clinical trials
