Study summary

This phase Ib/II trial evaluates the safety, optimal dose, and efficacy of the combination of epcoritamab and ibrutinib in treating patients with aggressive B-cell non-Hodgkin lymphoma that has come back (relapsed) or responded to previous treatment (refractory). Epcoritamab, a bispecific antibody, binds to two different types of receptors (proteins present on the cell surface) at the same time. The two receptors that epcoritamab binds to are called CD3 and CD20. CD3 is found on T cells, which are important cells of the immune system that help fight cancer and infections. CD20 is found on the surface of most types of aggressive B-cell non-Hodgkin lymphoma cells. By binding to both CD3 and CD20, epcoritamab brings the two cells close together so the T cells can fight and kill the lymphoma B cells. Ibrutinib, a Bruton's tyrosine kinase (BTK) inhibitor, binds to a protein on B cells, a type of white blood cell from which the lymphoma developed. By doing this it decreases the ability of the lymphoma B cells to survive and grow. Ibrutinib may also improve the health (or fitness) of T cells thus making epcoritamab safer and/or more effective.

Read the detailed description

PRIMARY OBJECTIVES:

I. Determine the recommended phase II dose (RP2D) and safety of epcoritamab plus ibrutinib.

II. Determine the rate and severity of cytokine release syndrome (CRS).

SECONDARY OBJECTIVES:

I. Determine the complete response (CR) rate (Lugano 2014) after cycle 12 or the last dose of treatment if stopped earlier.

II. Determine the overall response rate (ORR) (CR + partial response [PR]) (Lugano 2014), progression-free survival (PFS), duration of response (DOR), and overall survival (OS) of patients treated at the RP2D.

III. Determine the best ORR and CR rate (Lugano 2014).

EXPLORATORY OBJECTIVES:

I. Characterize cytokine profile following ibrutinib and epcoritamab and explore whether levels of cytokine production correlate with both the appearance of CRS and ORR.

II. Analyze peripheral blood mononuclear cells collected pre-ibrutinib, pre-epcoritamab, and throughout treatment using spectral flow cytometry to assess the effect of ibrutinib on T-cell numbers and function.

III. Examine tumor samples attained before starting treatment and at relapse and explore aspects of the microenvironment that may contribute to epcoritamab failure.

IV. Measure circulating tumor deoxyribonucleic acid (DNA) (ctDNA) to correlate its presence with response by positron emission tomography (PET) imaging and track the emergence of treatment-resistant clones.

OUTLINE:

Patients receive ibrutinib orally (PO) once daily (QD) on days -7 to 28 of cycle 1 and on days 1 to 28 of remaining cycles, as well as epcoritamab subcutaneously (SC) on days 1, 8, 15 and 22 of cycles 1-3, days 1 and 15 of cycles 4-9, and on day 1 of remaining cycles. Treatment repeats every 28 days for up to 6 cycles of ibrutinib and up to 12 cycles of epcoritamab in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo blood sample collection, computed tomography (CT) and PET/CT throughout the study. Patients may also undergo bone marrow aspiration and biopsy on study.

After completion of study treatment, patients are followed up every 3 months for 2 years then every 6 months for up to 5 years.

Terms in these criteria, in plain language(28)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

GVHD (graft-versus-host disease)

After a transplant from a donor, the donor’s immune cells attack the recipient’s body, often the skin, gut or liver.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

CYP3A (CYP3A4) inhibitors and inducers

CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

What researchers measure

Primary outcomes

  1. Incidence of adverse events (AEs)

    AEs will be tabulated by type and grade using the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 and displayed in summary form. The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns.

    Time frame: Up to 60 days after last dose of study drug

  2. Incidence of cytokine release syndrome (CRS)

    CRS severity will be graded using American Society for Transplantation and Cellular Therapy Cytokine Release Syndrome criteria. The CRS rate will be calculated together with 95% one-sided confidence intervals among evaluable patients.

    Time frame: Up to 60 days after last dose of study drug

Secondary outcomes

  1. Overall response rate (ORR)

    ORR will be defined as the proportion of patients achieving a complete or partial response and reported with a 95% binomial confidence interval.

    Time frame: Up to 24 months

  2. Complete response (CR) rate

    Time frame: Up to cycle 12 (each cycle is 28 days)

  3. Progression-free survival (PFS)

    PFS will be defined for all patients who begin treatment therapy to the date of progression or death. PFS will be estimated using the method of Kaplan-Meier, where estimates at time points of interest will be reported with 95% confidence intervals. Median PFS will be evaluated if estimable.

    Time frame: From the start of treatment to the time of progression or death, whichever occurs first, assessed up to 5 years

  4. Duration of response (DOR)

    Time frame: Up to 5 years

  5. Overall survival (OS)

    OS will be defined for all patients who begin treatment therapy to the date of death from any cause. OS will be estimated using the method of Kaplan-Meier, where estimates at time points of interest will be reported with 95% confidence intervals. Median OS will be evaluated if estimable.

    Time frame: From the start of treatment to death from any cause, assessed up to 5 years

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2025 (actual). Primary completion is estimated for Aug 2027, 28 months after the start.

Of 57 non-industry phase 1/2 interventional studies under Lymphoma, Large B-Cell, Diffuse, half reached primary completion within 66 months of starting (the median), counting those still running; a quarter within 46 and three quarters within 94. This study's planned 28 months is below that.

Counting every sponsor, half of 108 studies reached it within 70 months; a quarter within 50 and three quarters within 98.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 25, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
