Receives: Drug: Zanubrutinib; Drug: Tafasitamab

What is being measured

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

  1. Phase 1: Recommended Phase 2 Dose (RP2D) of Zanubrutinib

    Determination of the RP2D of Zanubrutinib, when used in combination with Tafasitamab, based on evaluation of dose limiting toxicity (DLT) in participants during the Phase 1 part of the study. DLT will be defined as the occurrence of specified adverse events (AEs) at least possibly related to the study therapy during the DLT review period.

    Measured: 4 weeks

  2. Phase 2: Rate of Complete Response (CR) to Zanubrutinib at RP2D

    The complete response (CR) rate among study participants in Phase 2 to Zanubrutinib at the RP2D in combination with Tafasitamab will be assessed. Response will be assessed using positron emission tomography (PET)/computerized tomography (CT) according to the Lugano 2014 criteria. CR will be defined by a Deauville score of less than or equal to (≤) 3.

    Measured: Up to 48 weeks

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

    The overall response rate (ORR) in study participants will be assessed. ORR will be defined at the percentage of participants achieving complete response (CR) or partial response to study therapy at at the end of early (cycles 1-3) and late induction (cycles 4-12). Response to treatment will be assessed using PET/CT according to Lugano 2014 criteria after weeks 12 and 48 of treatment. CR will be defined by a Deauville score of ≤ 3, and PR by a Deauville score of 4 or 5 with reduced uptake from baseline.

    Measured: Up to 48 weeks

  2. Progression-free Survival (PFS)

    Progression-free survival among study participants will be assessed during treatment and clinical follow-up. PFS is defined as the time from start of treatment until disease progression or death.

    Measured: Up to 48 months

  3. Overall Survival (OS)

    Overall survival (OS) among study participants will be assessed during treatment and clinical follow-up. OS is defined from start of treatment until death from any cause.

    Measured: Up to 48 months

  4. Number of Participants Experiencing Treatment-related Adverse Events (AEs) and Serious Adverse Events (SAEs)

    The dosing, safety, and feasibility of combination of Zanubrutinib and Tafasitamab will be assessed and reported among study participants in Phase 1 as the number of participants experiencing treatment-related toxicity after start of study therapy, including treatment-related adverse events (AEs) and serious adverse events (SAEs). AEs and SAEs will be assessed using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5, per physician discretion.

    Measured: Up to 27 months

  5. Phase 2: Duration of Response (DOR)

    The duration of response (DOR) among study participants will be assessed during treatment and clinical follow-up. DOR is defined as the time from randomization to disease progression or death in patients who achieve complete response (CR) or partial response (PR).

    Measured: Up to 48 months

  6. Phase 2: Time to Next Treatment (TTNT)

    Time to next treatment (TTNT) is defined as the time between the date of initiation of proposed treatment and the date of next subsequent systemic treatment initiation. For participants who do not have a subsequent treatment, the TTNT will be censored at last date known to be alive, except that death from any cause will be considered a competing risk event.

    Measured: Up to 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Zanubrutinib and Tafasitamab in people with Mantle Cell Lymphoma, run by Alvaro Alencar, 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 16 inclusion and 23 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 21 Sep 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 Alvaro Alencar, MD ((305) 243-4372, aalencar@med.miami.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1: Recommended Phase 2 Dose (RP2D) of Zanubrutinib (time frame: 4 weeks). The study lists 2 primary outcomes in all. 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 21 Sep 2026; AzTrials last refreshed its copy on 26 Oct 2026.
