September 28, 2026 updated by: Estrella Immunopharma, Inc.

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.

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.
