Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Men and women ≥ 18 years of age on the day of signing the informed consent form (or the legal age of consent in the jurisdiction in which the study is taking place).
  • Patients must have histologic confirmation of large B-cell lymphoma (LBCL) defined by the World Health Organization (WHO) classification. All LBCL subtypes are acceptable. Note: Patients with prior treatment for indolent lymphoma are still eligible for participation as long as they did not receive anthracycline-based therapy.
  • Baseline 18-fluorodeoxyglucose (FDG)-positron emission tomography scan/computed tomography (PET/CT) must demonstrate FDG avid lesions compatible with CT-defined anatomical tumor sites (Note: FDG-PET/CT is not mandatory, and patients with CT scans only will be eligible for study entry as well). Patients should have at least 1 measurable site of disease per Lugano classification in FDG-PET/CT or CT scans.
  • Presence of systemic and CNS involvement (brain, cerebellum, brainstem, meninges, cranial nerves, eyes, spinal cord, or a combination of these) at presentation.
  • Determination of CNS involvement can be by brain biopsy, cerebrospinal fluid (CSF) evaluation by cytology and/or flow cytometry, neuroimaging, or strong clinical suspicion by Investigator for which CNS targeted therapy is recommended (ie, numb chin syndrome in patients with high CNS involvement risk).
  • Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≤ 2, except due to lymphoma involvement.
Show all 22Show fewer
  • Life expectancy of greater than ≥ 3 months.
  • Women should avoid becoming pregnant while taking zanubrutinib and for up to 90 days after ending treatment. Therefore, women of childbearing potential must use highly effective contraceptive measures while taking zanubrutininb and for up to 90 days after stopping treatment. It is currently unknown whether zanubrutinib may reduce the effectiveness of hormonal contraceptives, and therefore women using hormonal contraceptives should add a barrier method. Pregnancy testing is recommended for women of reproductive potential prior to initiating therapy.
  • Agreement to use contraception during study participation.
  • Female patients of childbearing potential must use highly effective methods of contraception. Recommended acceptable contraception methods are included in Section 5.12.
  • Patients using hormonal contraceptives (eg, birth control pills or devices) must use a barrier method of contraception (eg, condoms) as well.
  • A woman is considered of childbearing potential, ie, fertile, following menarche and until becoming postmenopausal unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy.
  • A post-menopausal state is defined as no menses for 12 months without an alternative medical cause.
  • Male patients with a female partner of childbearing potential are eligible if they abstained, are vasectomized or if they agree to the use of barrier contraception with other methods described above during the study treatment period and for 90 days after the last dose of zanubrutinib.
  • Patients must have normal organ and marrow function as defined below:
  • Absolute neutrophil count (ANC) > 1,000 cells/mm3 independent of growth factor support within 7 days of study entry (≥ 750 cells/mm3 if lymphoma involvement of the bone marrow or spleen).
  • Platelets ≥ 75,000 platelets/mm3 independent of transfusion support within 7 days of study entry (≥ 50,000/mm3 independent of transfusion support within 7 days of study entry if lymphoma involvement of the bone marrow or spleen).
  • Hemoglobin > 9 g/dL or > 8 g/dL in case of bone marrow involvement by lymphoma independent of transfusion support within 7 days of study entry.
  • Serum total bilirubin ≤ 2 x upper limit of normal (ULN; except patients with Gilberts syndrome).
  • Aspartate aminotransferase (AST; serum glutamic-oxaloacetic transaminase (SGOT)) and alanine transaminase (ALT); serum glutamic-pyruvic transaminase (SGPT)) ≤2.5 x institutional ULN (≤3x institutional ULN if lymphoma involvement of the liver).
  • Creatinine within normal institutional limits, or creatinine clearance ≥ 40 mL/min (as estimated by the Cockcroft-Gault equation or alternative formula according to institutional guidelines) for patients with creatinine levels above institutional normal.
  • Able to provide written informed consent and can understand and agree to comply with the requirements of the study and the schedule of assessments (SoA).

Who cannot join

  • Primary CNS lymphoma without evidence of systemic lymphoma.
  • Prior systemic lymphoma therapy (Note: 1 cycle of an anthracycline based regimen, such as rituximab, cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisone (R-CHOP), polatuzumab vedotin, rituximab, cyclophosphamide, doxorubicin, and prednisone (pola-R-CHP), dose-adjusted etoposide phosphate, prednisone, oncovin, cyclophosphamide, hydroxydaunorubicin, and rituximab (EPOCH-R), or rituximab, cyclophosphamide, vincristine, doxorubicin, and methotrexate (R-Codox-M), and/or 1 dose of intrathecal therapy, will be allowed before enrollment [Section 5.9]).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of participants experiencing dose-limiting toxicities (DLTs)

    The number of participants experiencing dose-limiting toxicities (DLTs) after starting study therapy. Toxicity will be assessed using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, per physician discretion.

    Measured: Up to 21 days

Secondary outcomes (6)
  1. Overall Response Rate (ORR)

    Overall response rate (ORR) is defined as the proportion of participants with complete response (CR) or partial response (PR) as the best response.

    Measured: Up to 5 years

  2. Number of Patients achieving conversion from PR to CR

    Conversion from PR to CR will be assessed by the number of patients achieving an initial PR followed by how many will achieve a subsequent CR by Lugano response criteria.

    Partial response (PR) will be calculated by a Deauville score of 4 or 5 with reduced uptake from baseline, and complete response (CR) is defined as a Deauville score of ≤ 3.

    Measured: Up to 5 years

  3. Progression-Free Survival (PFS)

    Progression-free survival (PFS) is defined as the elapsed time in years from the start of treatment until disease progression or death, whichever is earlier. Participants who remain alive without progression will be censored at the last documented disease assessment date.

    Measured: Up to 5 years

  4. Overall Survival (OS)

    Overall survival (OS) is defined as the elapsed time in years from the start of treatment until death from any cause. Alive participants will be censored at the last date known to be alive.

    Measured: Up to 5 years

  5. Number of participants experiencing treatment-related adverse events (AEs)

    The number of participants experiencing treatment-related adverse events (AEs). AEs will be assessed using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, per physician discretion.

    Measured: Up to 42 months

  6. Number of participants experiencing treatment-related serious adverse events (SAEs)

    The number of participants experiencing treatment-related serious adverse events (SAEs). SAEs will be assessed using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, per physician discretion.

    Measured: Up to 42 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Zanubrutinib, Methotrexate and Polatuzumab Vedotin in people with CNS Lymphoma, run by Juan P. Alderuccio, MD at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 22 inclusion and 31 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 14 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Juan P Alderuccio, MD (+1 (347) 9312272, jalderuccio@med.miami.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants experiencing dose-limiting toxicities (DLTs) (time frame: Up to 21 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 May 2026.
