About this study

Official title: Orelabrutinib for the Treatment of Marginal Zone Lymphoma: A Phase II, Multicenter, Open-label Study

This is a single-arm, multicenter, prospective, phase II study. The primary objective is to assess the efficacy and safety of orelabrutinib in treatment-naïve patients with marginal zone lymphoma.

Read the detailed description

Marginal zone lymphoma (MZL) is a group of indolent B-cell malignancies originating from B lymphocytes, primarily occurring in the marginal zones of the spleen, lymph nodes, and mucosa-associated lymphoid tissues. Its histological features are characterized by abnormal proliferation of marginal zone cells surrounding lymphoid follicles. The Bruton tyrosine kinase (BTK) signaling pathway plays a critical role in B-cell receptor-mediated signal transduction and is significant in the development and progression of various B-cell malignancies. Ibrutinib, as the first BTK inhibitor, has demonstrated remarkable efficacy in the treatment of B-cell lymphomas. However, its poor kinase selectivity leads to a high incidence of off-target toxicities, including thrombocytopenia, neutropenia, bleeding, fatigue, rash, and atrial fibrillation in clinical settings, which limits its long-term use. Orelabrutinib is a highly selective oral small-molecule BTK inhibitor belonging to the nicotinamide class of compounds. It covalently binds to BTK and represents a new generation of selective irreversible BTK inhibitors. Due to its higher selectivity for BTK and favorable safety profile observed in previous human studies, orelabrutinib holds promise as a superior therapeutic option for B-cell malignancies. To further improve clinical outcomes for MZL patients, there is an urgent need to explore treatment strategies with better efficacy and lower toxicity. This study aims to evaluate the efficacy and safety of orelabrutinib in previously untreated localized-stage MZL patients, providing new therapeutic evidence for this population.

This study is a multicenter, prospective trial involving previously untreated patients with MZL. During the induction phase (cycles 1-6), patients will receive orelabrutinib 150 mg, administered in 28-day treatment cycles. Following completion of the induction phase, patients will be followed during a post-treatment follow-up period.

What is being measured

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

  1. Overall response rate (ORR)

    The ORR is defined as the proportion of patients with a response of CR or PR.

    Measured: From the initiation of treatment to the end of induction therapy of cycle 6 (each cycle is 28 days)

Secondary outcomes (6)
  1. Complete response rate (CRR)

    Complete response rate is defined as the proportion of patients with a response of CR.

    Measured: From the initiation of treatment to the end of induction therapy of cycle 6 (each cycle is 28 days)

  2. Time to response (TTR)

    TTR is defined as the time from the start of therapy to the first response.

    Measured: 1years

  3. Duration of Response (DOR)

    DOR is defined as the time from documentation of response to treatment to the first documentation of tumor progression or death due to any cause, whichever comes first.

    Measured: From the first demonstration of response until disease progression/death, up to 1 years

  4. Progression-free survival (PFS)

    PFS is defined as the time from enrollment to disease progression or death from any cause. For patients who remain alive and progression-free at the data cutoff date, PFS will be censored at the last tumor assessment date.

    Measured: From the date of enrollment until the date of first documented progression, up to 2 years

  5. Overall survival (OS)

    OS is defined as the time from the initiation of treatment to death from any cause. Patients alive at the data cutoff date will have their OS censored at the date of the last follow-up.

    Measured: From the date of the initiation of treatment until the date of death, up to 2 years

  6. Adverse events (AEs)

    AEs will be graded according to the NCI-CTCAE Version 5.0.

    Measured: From the date of enrollment until the date of death, up to 1 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Orelabrutinib in people with Marginal Zone Lymphoma, run by Institute of Hematology & Blood Diseases Hospital, China at 14 sites in China.

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 9 inclusion and 15 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 2 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in China. 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 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 Shuhua Yi (022-23909035, yishuhua@ihcams.ac.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall response rate (ORR) (time frame: From the initiation of treatment to the end of induction therapy of cycle 6 (each cycle is 28 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 2 Mar 2026.
