Terapia con cellule T (EB103) negli adulti con linfoma non Hodgkin (NHL) a cellule B recidivante/refrattario (STARLIGHT-1)

28 settembre 2026 aggiornato da: Estrella Immunopharma, Inc.

Uno studio clinico multicentrico di fase I/II in aperto, con incremento della dose, sulla terapia con cellule T EB103 in adulti affetti da linfoma non Hodgkin (NHL) a cellule B recidivante/refrattario (R/R)

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.

Descrizione dettagliata

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.
