- description
- All AEs/SAEs were recorded from admission for pre-conditioning chemotherapy (Day -6 relative to AUTO4). Due to the long period between consent and AUTO4 treatment, any AEs/SAEs related to bridging chemotherapy not associated with study procedures did not require reporting as study AEs/SAEs. Any significant events were added to the patient's medical history. All AEs/SAEs related to study procedures (leukapheresis, bone marrow assessments) were reported.

- DOR was defined as the time from the first observed CR or partial response (PR) to documented disease progression or death due to any cause, for patients who were considered as responders. Patients who received protocol specified anti-cancer treatment post AUTO4 infusion were ignored in the main analysis. Patients who proceeded to stem cell transplantation (SCT) after AUTO4 infusion were censored at the time of SCT (including the conditioning regimen for SCT). Patients who received new non-protocol anticancer therapies other than SCT were censored at the date of last adequate assessment prior to the new therapy. Patients who experienced event after missing two or more scheduled disease assessments were censored at the date of last adequate assessment prior to the event. Data for DOR were pooled for analysis because the number of patients was \<5 for all of the groups and the intended model cannot be built with such a small sample size.

- PFS was defined as the time from the first treatment of AUTO4 to documented disease progression/relapse or death due to any cause. If a patient did not have relapse or death due to any reason prior to data cut-off, PFS was censored at the date of the last adequate assessment by default. Patients who received protocol specified anti-cancer treatment post AUTO4 infusion were ignored in the main analysis. Patients who proceeded to SCT after AUTO4 infusion were censored at the time of SCT (including the conditioning regimen for SCT). Patients who received new non-protocol anticancer therapies other than SCT were censored as the date of last adequate assessment prior to the new therapy.

Full study description
- brief Summary
- The purpose of this study is to test the safety and efficacy of AUTO4 a chimeric antigen receptor (CAR) T cell treatment targeting TRBC1 in patients with relapsed or refractory TRBC1 positive selected T-Non-Hodgkin Lymphoma (NHL).
- detailed Description
- The study will consist of 2 phases, a Phase I/dose escalation phase and a Phase II/expansion phase. Patients with relapsed or refractory TRBC1 positive selected T-NHL will be enrolled in both phases of the study. Eligible patients will undergo leukapheresis to harvest T cells, the starting material for the manufacture of the autologous CAR-T product AUTO4. Following preconditioning by a chemotherapeutic regimen, the patient will receive AUTO4 intravenously as a single dose following which they will then enter a 24-month follow-up period
