About this study

Official title: An Open-Label, Dose Escalation, Multi-Center Phase I/II Clinical Trial of EB103 T-Cell Therapy in Adults With Relapsed/Refractory (R/R) B-Cell Non-Hodgkin's Lymphoma (NHL)

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.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EB103Biological

    EB103 is an autologous T-cell therapy whereby a subject's own T cells are transduced with a lentiviral vector expressing the EB103 transgene.

    The peak exposure (Cmax) will be measured in our study subject population.

    Measured: Time Frame: Up to 2 years

  8. To characterize the pharmacokinetic (PK) profile of EB103 by measuring the time to reach peak exposure (Tmax).

    Time to reach peak exposure (Tmax) will be measured in our study subject population.

    Measured: Time Frame: Up to 2 years

  9. To characterize the pharmacokinetic (PK) profile of EB103 by measuring the partial area under the curve (pAUC).

    Partial area under the curve (pAUC) will be measured in our study subject population.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing EB103 in people with B-Cell Non-Hodgkin's Lymphoma (NHL) and Lymphoma, Non-Hodgkins, run by Estrella Immunopharma, Inc. at 5 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 18 inclusion and 20 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: looking for participants now, as of the sponsor's last update on 1 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Contact Teresa Klask, MBA (925-949-9314, teresa.klask@eurekainc.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To assess the safety and tolerability of EB103. (time frame: Up to 2 years (active assessment period); additional long-term follow-up (LTFU) up to 15 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 1 Oct 2026; AzTrials last refreshed its copy on 3 Nov 2026.
