New treatment option for Non-hodgkin Lymphoma,B Cell
Official title Allogeneic TRAC Locus-inserted CD19-targeting STAR T Cell Therapy in r/r B-NHL
ClinicalTrials.gov ID: NCT06321289
What this study is testing
What is Allogeneic CD19-STAR T cell?
Allogeneic CD19-STAR T cell is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for non-hodgkin lymphoma,b cell.
Also referred to as Allogeneic CD19-targeting synthetic T-cell receptor antigen receptor T cells.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The team has developed the synthetic T cell receptor (TCR) and antigen receptor (STAR) T cells which were demonstrated safety in relapsed or refractory (r/r) B-cell non-Hodgkin' s lymphoma (B-NHL) (NCT05631912). Based on this research, allogeneic STAR-T cell products utilized the CRISPR-Cas9 gene editing tool to knock out endogenous receptor α constant (TRAC), human leukocyte antigen (HLA)-A/B, CIITA, and programmed death 1 (PD-1) genes simultaneously in T cells from healthy donors, and integrated the STAR molecule into the TRAC locus using adenovirus associated virus.
