Study summary

This is a phase II study designed to evaluate the toxicity and efficacy of the combination of loncastuximab tesirine and epcoritamab in patients with relapsed/refractory aggressive B-cell lymphoma. Chimeric antigen receptor (CAR)-T cell naive patients who have failed first-line therapy and patients who have received CAR-T cells as second-line therapy and experienced CAR-T failure will be eligible for inclusion.

Read the detailed description

A total of 120 patients will be included. 60 days after 20 patients have started the therapy, a safety analysis will be performed to identify early and unexpected side effects of the combination therapy. An interim analysis will be conducted 6 months after recruitment of the 50th patient to check the effectiveness of the therapy. For patients not pretreated with CAR-T cells, an additional and separate efficacy analysis will be performed after the 20th CAR-T naive patient started treatment with loncastuximab tesirine and epcoritamab and had a second response assessment (12 weeks after treatment initiation) by FDG-PET/CT (-/MRI).

Inclusion criteria

Disease:

  1. Subjects with confirmed DLBCL based on pathology report (WHO 2022 criteria)

    1. DLBCL (de novo or transformed)
    2. High-grade B-cell lymphoma with MYC and BCL2 rearrangements
    3. High-grade B-cell lymphoma, not otherwise specified (NOS)
    4. Follicular lymphoma grade 3B

    Diagnostic performed at the time of relapse/progressive disease no longer than 3 months before study entry must be available, with sufficient material for central review and complimentary scientific analyses. CD20 expression (or a high likelihood of CD20 expression) based on immunohistochemistry should be documented prior enrollment into the study.

    Refractory disease is defined as no remission to the last therapy. Subjects intolerant to previous therapy are excluded. Two groups of patients are eligible:

    • Progressive disease (PD) or stable disease (SD) as best response to previous therapy.
    • Complete (CR) or partial response (PR) as the best response after previous therapy, with biopsy-proven relapse occurring \< 6 months after end of treatment.

    Relapsed disease is defined as subjects achieving complete or partial remission to previous therapy, followed by biopsy-proven relapse ≥6 months after treatment completion.

    Subjects with refractory and early relapsed (≤12 months) disease after anti-CD20-/anthracycline-containing therapy are eligible. Subjects with late relapsed (>12 months) disease after first line anti-CD20-/anthracycline-containing therapy can be enrolled in the study only if deemed ineligible to high dose chemotherapy (HDCT) followed by stem cell transplantation (ASCT)) or if refuse to undergo HDCT/ASCT. Subjects relapsed/refractory to second line CAR-T cell therapy are eligible.

  2. Subject must be 18 years or older.
  3. Subject must be eligible to receive and in need of treatment initiation based on symptoms and/or disease burden, as assessed by the investigator.
  4. Performance (ECOG) status 0-2.
  5. Subject must have one or more sites defined as follows:

    1. A positron emission tomography/computed tomography (PET/CT) scan demonstrating PET- positive lesion(s) AND
    2. At least one measurable nodal lesion (long axis > 1.5 cm and short axis > 1.0 cm) or ≥ one measurable extra-nodal lesion (long axis > 1.0 cm) on CT scan or MRI.
  6. Ability to understand and willingness to sign written . Signed informed consent must be obtained before any study specific procedure.

    :

  7. Women of and sexually active men must practice a highly effective method of birth control during and after the study, consistent with local regulations regarding the use of birth control methods for subjects participating in clinical trials. Men with female partners who are of childbearing potential must agree to use a condom when sexually active or practice total abstinence from the time of giving informed consent until at least 7 months after the patient receives his last dose of study treatment. Men must agree not to donate sperm from the time of giving informed consent until at least 7 months after the patient receives his last dose of study treatment. For female subjects, they apply for 12 months after the last dose of the study drug. A woman is considered to be of childbearing potential until becoming or permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy. Post-menopausal status is defined as no menstrual periods for a continuous 12-month period without an alternative medical cause. A post-menopausal state can be confirmed by a high follicle-stimulating hormone (FSH) level within the postmenopausal range, especially in women not using hormonal contraception or replacement therapy. The investigator or a designated associate will provide guidance to patients on achieving highly effective contraception (with a failure rate of less than 1%), such as intrauterine devices, intrauterine hormone-releasing systems, bilateral tubal occlusion, having a vasectomized partner, or sexual abstinence. Male patients are required to use condoms unless their female partner is permanently sterile.
  8. Women of childbearing potential participating in the study will be required to undergo a pregnancy test using either urine or serum beta-human chorionic gonadotropin (beta-hCG) at the screening visit. A negative result is necessary for inclusion in the study.

    Adequate baseline organ function tests collected no more than 7 days before starting study treatment:

  9. Total ≤ 1.5 times the (ULN), except for patients with Gilbert syndrome, cholestasis due to hepatic hilum adenopathies or liver involvement, or biliary obstruction due to lymphoma, who may have a total bilirubin ≤ 3 times the ULN.
  10. (ALT) and aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) ≤ 2.5 times the ULN, or ≤ 5 times the ULN for patients with liver involvement by lymphoma.
  11. (GFR) ≥ 45 mL/min/1.73 m² according to the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. If not initially within target range, this evaluation may be repeated after at least 24 hours, either using the CKD-EPI formula or by 24-hour sampling. If the subsequent result is within the acceptable range, it may be used to fulfill the inclusion criteria.
  12. /international normalized ratio (INR)/activated partial thromboplastin time (aPTT) ≤ 1.5 times the ULN, unless the patient is receiving anticoagulation (although the INR should not exceed 4.0).
  13. count ≥ 75,000/mm³ without transfusion in the prior 7 days.
  14. ≥ 8 g/dL.
  15. ≥ 1,000/mm3 (off growth factors at least 72 hours).
  16. > 45%.

    Concomitant Medications:

  17. Subjects should not be taking any active medication known to decrease T-cell numbers or activity, or any other concurrent medication, except for up to 10 mg of prednisone daily or an equivalent dose, unless it is necessary for disease control during the screening period, premedication and/or cytokine release syndrome (CRS)/ immune effector cell-associated neurotoxicity syndrome (ICANS) management within the study.
  18. Subjects must not have been treated with any drug within 30 days or 5 half-lives of the drug (whichever is longer) prior to the first dose of the study drug. They should not be currently enrolled in another interventional clinical study or have been previously enrolled in this study, unless the agent being used has been approved under emergency authorization (e.g., anti-severe acute respiratory syndrome coronavirus (SARS-CoV-2) monoclonal antibodies).
  19. Acute toxicity (except alopecia, fatigue) of any prior lymphoma therapy should be resolved to Grade ≤ 1 (with the exception of prior CRS or ICANS that should be fully resolved) at study screening.
  20. The subject should not have received vaccination with within 28 days prior to screening, and they should not be expected to require any live-attenuated vaccination during their participation in the study, including at least 3 months following the last dose of study treatment. However, vaccination with coronavirus messenger ribonucleic acid (mRNA) and adenovirus-based vaccines, which are not live-attenuated vaccines, is permitted.

Terms in these criteria, in plain language(33)

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.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

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.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

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.

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.

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.

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.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

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.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

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).

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.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

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.

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.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

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.

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

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.

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.

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.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Of 151 non-industry phase 2 interventional studies under Lymphoma, Follicular, half reached primary completion within 67 months of starting (the median), counting those still running; a quarter within 40 and three quarters within 110. This study's planned 53 months is below that.

Counting every sponsor, half of 199 studies reached it within 57 months; a quarter within 31 and three quarters within 97.

How these figures are worked out, and which studies are left out of them.

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 Jul 30, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
