Because the list of these agents is constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
  • Patients with known UGT1A1 genetic polymorphisms, such as UGT1A1*28, are excluded as they can have reduced UGTA1A activity and may be at risk for increased belinostat exposure

About this study

Official title: Phase 1/Expansion Study of Tazemetostat Plus Belinostat for the Treatment of Relapsed or Refractory Lymphoma

This phase I trial tests the safety, side effects, and best dose of combination therapy with tazemetostat and belinostat in treating patients with lymphoma that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). Tazemetostat is in a class of medications called EZH2 inhibitors. The EZH2 gene provides instructions for making a type of enzyme called histone methyltransferase which is involved in gene expression and cell division. Blocking EZH2 may help keep cancer cells from growing. Belinostat is in a class of medications called histone deacetylase inhibitors. Histone deacetylases are enzymes needed for cell division. Belinostat may kill cancer cells by blocking histone deacetylase. It may also prevent the growth of new blood vessels that tumors need to grow and may help make cancer cells easier to kill with other anticancer drugs. There is some evidence in animals and in living human cells that combination therapy with tazemetostat and belinostat can shrink or stabilize cancer, but it is not known whether this will happen in people. This trial may help doctors learn more about treatment of patients with relapsed or refractory lymphoma.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the maximum tolerated dose (MTD) and dose limiting toxicities (DLTs) of tazemetostat and belinostat in combination in patients with relapsed or refractory lymphoma. (Phase I: Dose escalation) II. Evaluate the safety and toxicity of the combination tazemetostat and belinostat. (Phase I: Dose escalation) III. Assess the safety and tolerability of tazemetostat and belinostat in patients with germinal-center derived B-cell lymphoma (follicular lymphoma, transformed disease, diffuse large B-cell lymphoma germinal center B-cell type [GC-DLBCL] defined by Hans criteria), and T-cell lymphomas. (Phase I: Dose expansion) IV. Assess the impact of EZH2, CREBBP, and EP300 mutations on response to dual epigenetic targeting. (Phase I: Dose expansion)

SECONDARY OBJECTIVES:

  1. To observe and record anti-tumor activity. II. To evaluate the pharmacokinetic profile for tazemetostat and belinostat when given as a combination.

III. Define the overall response rate (ORR), progression free survival (PFS), and duration of response (DOR) in patients with relapsed or refractory EZH2 mutated and EZH2 wild-type germinal-center derived B-cell lymphoma (follicular lymphoma, transformed disease, GC-DLBCL defined by Hans criteria), as well as T-cell lymphomas.

IV. To describe the maximum number of cycles received, the number of dose reductions and delays at the MTD.

EXPLORATORY OBJECTIVES:

  1. Determine a biomarker for response by assessing the basal mutation and gene expression status of key epigenetic regulators and correlating this signature with the response to the combination.

II. Determine the change in gene expression in tumor tissue following exposure the combined epigenetic therapy.

III. Determine the effect of combination epigenetic therapy on modulation of acetylation and methylation of histone K27.

IV. Determine the effect of combination epigenetic therapy on modulation of the immune response.

OUTLINE: This is a phase I dose-escalation study of tazemetostat and belinostat followed by a dose-expansion study.

Patients receive tazemetostat orally (PO) twice daily (BID) on days 2-21 of cycle 1 and days 1-21 of subsequent cycles, and belinostat intravenously (IV) over 30-180 minutes on days 1-5 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Patients may undergo a tumor biopsy during screening and on study (dose-expansion only). Patients undergo blood sample collection while on study and computed tomography (CT) or positron emission tomography (PET)/CT scan throughout the study.

After completion of study treatment, patients are followed up at 4 weeks, then every 3 months for a year or until they begin a new treatment for their disease.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Belinostat, Biopsy Procedure and Biospecimen Collection in people with Recurrent B-Cell Non-Hodgkin Lymphoma and Recurrent Diffuse Large B-Cell Lymphoma Germinal Center B-Cell Type, run by National Cancer Institute (NCI) at 11 sites 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 25 inclusion and 12 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: under way, not looking for participants, as of the sponsor's last update on 18 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 11 sites 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum tolerated dose (Dose escalation) (time frame: Up to end of cycle 1 (Cycles = 21 days)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05627245.

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 18 Sep 2026.
