NCT05627245

Brief Summary

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.

Study Arms (1)

Treatment (tazemetostat, belinostat)

EXPERIMENTAL

Patients receive tazemetostat PO BID on days 2-21 of cycle 1 and days 1-21 of subsequent cycles, and belinostat 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 CT or PET/CT scan throughout the study.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • DOSE ESCALATION PHASE: Patients with relapsed or refractory non-Hodgkin lymphoma including both B-cell non-Hodgkin lymphoma (NHL) and T-cell NHL. Refractory cutaneous T-cell lymphoma (CTCL) will be allowed if greater or equal to stage 1B and have previously failed two systemic therapies
  • DOSE EXPANSION PHASE: Patients with relapsed or refractory follicular, transformed lymphoma or germinal center B-cell diffuse large B-cell Lymphoma (GCB-DLBCL) as defined by Hans criteria, as well as T-cell lymphomas. For patients with B-cell lymphomas, equal numbers of patients will be enrolled onto one of 2 arms: (1) mutated EZH2 or (2) wild-type EZH2. EZH2 mutations will be identified by polymerase chain reaction (PCR)
  • Patients must not be eligible for, or have refused, stem cell transplantation or chimeric antigen receptor T-cell (CAR T-cell) therapy
  • Patients who have undergone 1-5 prior treatments of any type (progression after transplant/cellular therapy allowed) are eligible
  • Patients must have measurable disease according to the Lugano classification
  • Age \>= 18 years. Because no dosing or adverse event data are currently available on the use of tazemetostat in combination with belinostat in patients \< 18 years of age, children are excluded from this study
  • Eastern Cooperative Oncology Group (ECOG) performance status =\< 2 (Karnofsky \>= 60%)
  • Absolute neutrophil count \>= 1,000/mcL
  • If there is documented lymphomatous involvement of the bone marrow as assessed by bone marrow biopsy within 90 days prior to registration, participants should have: absolute neutrophil count (ANC) \>= 0.75 Ă— 10\^9/L
  • Platelets \>= 75,000/mcL
  • If there is documented lymphomatous involvement of the bone marrow as assessed by bone marrow biopsy within 90 days prior to registration, participants should have: platelets \>= 50 x 10\^9/L
  • Total bilirubin =\< 1.5 institutional upper limit of normal (ULN); unless due to Gilbert's disease, hemolysis, or lymphomatous involvement of liver, in which case total bilirubin should be =\< 5 x institutional ULN
  • Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 3 x institutional ULN; unless due to Gilbert's disease, hemolysis, or lymphomatous involvement of liver, in which case AST(SGOT)/ALT(SGPT) should be =\< 5 x institutional ULN
  • Glomerular filtration rate (GFR) \>= 30 mL/min/1.73 m\^2
  • Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial
  • +10 more criteria

You may not qualify if:

  • Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities \> grade 1) with the exception of alopecia
  • Patients who are receiving any other investigational agents
  • Patients with active central nervous system (CNS) metastases, including lymphomatous meningitis, as the study drugs are not known to effectively treat CNS disease
  • History of allergic reactions attributed to belinostat or tazemetostat, or to compounds of similar chemical or biologic composition to these agents
  • Patients receiving any medications or substances that are strong or moderate inhibitors or inducers of CYP3A4 within 14 days prior to study treatment are ineligible. Patients receiving strong UGT1A1 inhibitors are ineligible due to expected increased exposure to belinostat and potential for increased toxicity. 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
  • Patients with uncontrolled intercurrent illness
  • Pregnant women are excluded from this study because belinostat, as an HDAC inhibitor, and tazemetostat, as an EZH2 inhibitor, both have the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with belinostat and tazemetostat, breastfeeding should be discontinued if the mother is treated with belinostat and tazemetostat. Women of childbearing potential must have negative urine or serum pregnancy test to be eligible for this study
  • Systemic steroids that have not been stabilized to the equivalent of =\< 10 mg/day prednisone prior to the start of the study drugs and throughout the study. Patients are allowed to receive dexamethasone as premedication during belinostat infusion
  • Has thrombocytopenia, neutropenia, or anemia of grade \>= 3 (per Common Terminology Criteria for Adverse Events \[CTCAE\] 5.0 criteria) or any prior history of myeloid malignancies, including myelodysplastic syndrome (MDS)
  • Has abnormalities known to be associated with MDS (e.g. 5q deletion \[del 5q\], chromosome 7 abnormality \[chr 7 abn\]) and multiple primary neoplasms (MPN) (e.g. JAK2 V617F) observed in cytogenetic testing and deoxyribonucleic acid (DNA) sequencing
  • Has a prior history of T lymphoblastic lymphoma/T acute lymphoblastic leukemia (T-LBL/T-ALL)
