Acalabrutinib, Umbralisib, and Ublituximab for the Treatment of Previously Untreated Mantle Cell Lymphoma
A Phase II Study of BTK Inhibitor Acalabrutinib and PI3Kδ Inhibitor Umbralisib in Combination With Ublituximab (AU2) in Patients With Previously Untreated Mantle Cell Lymphoma (MCL)
Source: ClinicalTrials.gov · Last updated 6 Oct 2026
Brief summary (registry, in English)
This phase II trial studies the effects of acalabrutinib, umbralisib, and ublituximab in treating previously untreated mantle cell lymphoma. Acalabrutinib and umbralisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Ublituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Giving acalabrutinib and umbralisib with ublituximab may work better in treating mantle cell lymphoma.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Chronic use of corticosteroids \>= 20 mg/day (short-term use of steroids \< 14 days is 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
- Concurrent participation in another therapeutic clinical trial
- Subjects for whom the goal of therapy is tumor debulking before stem cell transplant
- 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
- Presence of a gastrointestinal ulcer diagnosed by endoscopy within 3 months before screening
- History of significant cerebrovascular disease/event, including stroke, myocardial infarction or intracranial hemorrhage, within 6 months prior to start of protocol therapy
- Inability to swallow and retain an oral medication
- Live virus vaccines within 4 weeks of start of protocol therapy or planned administration of live virus vaccines during ublituximab therapy
Other illness
- Known history of hypersensitivity or anaphylaxis to study drug(s) including active product or excipient components
- Uncontrolled AIHA (autoimmune hemolytic anemia) or ITP (idiopathic thrombocytopenic purpura)
- 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
- Known bleeding disorders (e.g., von Willebrand's disease or hemophilia)
- 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
- Unstable angina (angina symptoms at rest), new-onset angina (begun within the last 6 months)
- History of or current progressive multifocal leukoencephalopathy (PML)
- Clinically significant uncontrolled illness, including active infection requiring antibiotics
- Known history of human immunodeficiency virus (HIV) infection
- 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
Lab values
- 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
Age
- 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 (e.g., cervical, esophageal, etc.) without evidence of disease; asymptomatic prostate cancer managed with "watch and wait" strategy
Other
- Known active central nervous system (CNS) involvement by lymphoma, including leptomeningeal involvement
- Females only: Pregnant or breastfeeding
- 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)
