allowed)
- Major surgical procedure within 28 days of start of protocol therapy. Note: If a
subject had major surgery, they must have recovered adequately from any toxicity
and/or complications from the intervention before the first dose of study drug
- Known history of hypersensitivity or anaphylaxis to study drug(s) including active
product or excipient components
- Concurrent participation in another therapeutic clinical trial
- Subjects for whom the goal of therapy is tumor debulking before stem cell transplant
- History of prior malignancy. Exceptions include malignancy treated with curative
intent and no known active disease present for >= 2 years prior to initiation of
protocol therapy; adequately treated non-melanoma skin cancer or lentigo maligna
(melanoma in situ) without evidence of disease; adequately treated in situ carcinomas

cancer managed with "watch and wait" strategy
- Uncontrolled AIHA (autoimmune hemolytic anemia) or ITP (idiopathic thrombocytopenic
purpura)
- Requires treatment with proton pump inhibitors (e.g., omeprazole, esomeprazole,
lansoprazole, dexlansoprazole, rabeprazole, or pantoprazole). Subjects receiving
proton pump inhibitors who switch to H2-receptor antagonists or antacids are eligible
for enrollment to this study
- Requires treatment with a strong cytochrome P450 3A4 (CYP3A4) inhibitor/inducer
- Requires or receiving anticoagulation with warfarin or equivalent vitamin K
antagonists
- Malabsorption syndrome, disease significantly affecting gastrointestinal function, or
resection of the stomach or small bowel that is likely to affect absorption,
symptomatic inflammatory bowel disease, partial or complete bowel obstruction, or
gastric restrictions and bariatric surgery, such as gastric bypass
- Presence of a gastrointestinal ulcer diagnosed by endoscopy within 3 months before
screening
- Known bleeding disorders (e.g., von Willebrand's disease or hemophilia)
- History of significant cerebrovascular disease/event, including stroke, myocardial
infarction or intracranial hemorrhage, within 6 months prior to start of protocol
therapy
- Known active central nervous system (CNS) involvement by lymphoma, including
leptomeningeal involvement
- Clinically significant cardiovascular disease such as symptomatic arrhythmias,
congestive heart failure, or myocardial infarction within 6 months of screening, or
any class III or IV cardiac disease as defined by the New York Heart Association
Functional Classification. Note: Subjects with controlled, asymptomatic atrial
fibrillation can enroll on study

months)

antibiotics
- Live virus vaccines within 4 weeks of start of protocol therapy or planned
administration of live virus vaccines during ublituximab therapy
- Evidence of chronic active hepatitis B (HBV, not including patients with prior
hepatitis B vaccination; or positive serum Hepatitis B antibody) or chronic active
hepatitis C infection (HCV), or active cytomegalovirus (CMV). If hepatitis B virus
core (HBc) antibody is positive, the subject must be evaluated for the presence of HBV
deoxyribonucleic acid (DNA) by polymerase chain reaction (PCR). If HCV antibody is
positive, the subject must be evaluated for the presence of HCV RNA by PCR. If the
subject is CMV IgG or CMV IgM positive, the subject must be evaluated for the presence
of CMV DNA by PCR. Subjects with positive HBc antibody and negative HBV DNA by PCR are
eligible. Subjects with positive HCV antibody and negative HCV RNA by PCR are
eligible. Subjects who are CMV IgG or CMV IgM positive but who are CMV DNA negative by
PCR are eligible. Patients with a prior known history of hepatitis B and those with a
positive anti-HBc with negative hepatitis B surface antigen (HBsAg) at screening must
be able to receive antiviral agents effective against hepatitis B
- Known history of human immunodeficiency virus (HIV) infection
- Females only: Pregnant or breastfeeding
- Any other condition that would, in the Investigator's judgment, contraindicate the
patient's participation in the clinical study due to safety concerns with clinical
study procedures
- Prospective participants who, in the opinion of the investigator, may not be able to
comply with all study procedures (including compliance issues related to
feasibility/logistics)
