Among the 398 studies in Lymphoma, B-Cell with a site in United States, from their registry updates:
This is an open-label, multi-center, Phase 1/2 clinical trial evaluating the safety and effectiveness of EB103 in R/R B-cell NHL patients with the highest unmet medical needs, such as Human Immunodeficiency Virus (HIV)-associated lymphoma, primary and secondary central nervous system (CNS) lymphoma, and a wide range of high-grade B-cell lymphomas (HGBLs), as well as R/R large B-cell lymphoma (LBCL) patients ineligible for autologous transplant.
EB103 is an engineered T-cell therapy built on the ARTEMIS® Cell Receptor Platform.
This study consists of a completed Phase 1 portion and an ongoing Phase 2 expansion portion.
In Phase 1, a traditional 3+3 dose-escalation design was used to evaluate the safety and tolerability of EB103 and to determine the recommended Phase 2 dose (RP2D). Following dose escalation, an RP2D confirmatory cohort was enrolled to further characterize the safety profile of EB103 at the selected dose.
Phase 2 is an expansion cohort in which additional subjects will be enrolled and treated at the RP2D to further evaluate the safety and preliminary efficacy of EB103.
The active assessment period extends for 2 years (24 months) after the EB103 infusion (Day 0). Subjects then enter long-term follow-up (LTFU) for ongoing safety and overall survival assessments through Year 15.

disease
Relapsed or refractory disease, defined as ONE OR MORE of the following modified SCHOLAR-1 criteria (Crump, 2017):
Subjects with PCNSL with following status, if deemed appropriate by the Investigator, can be enrolled:
Diagnosis and disease assessment
Exclusion Criteria:
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.
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.
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: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
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.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
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.
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.
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.
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.
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.
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 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.
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.
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.
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.
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.
After a transplant from a donor, the donor’s immune cells attack the recipient’s body, often the skin, gut or liver.
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.
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.
A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.
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.

Started Jun 2024 (actual). Primary completion is estimated for Jul 2027, 37 months after the start.
Of 94 phase 1/2 interventional studies under Lymphoma, B-Cell, half reached primary completion within 71 months of starting (the median), counting those still running; a quarter within 55 and three quarters within 96. This study's planned 37 months is below that.
Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 1, 2026: primary completion Dec 2026 → Jul 2027 and completion Dec 2027 → Jul 2028.
