Étude de phase 1/2 sur UCART22 chez des patients atteints de leucémie aiguë lymphoblastique CD22+ récidivante ou réfractaire (BALLI-01)
Étude ouverte d'escalade de dose et d'expansion de dose pour évaluer l'innocuité, l'expansion, la persistance et l'activité clinique d'UCART22 (cellules T allogéniques exprimant un récepteur d'antigène chimérique anti-CD22) chez des patients atteints de leucémie aiguë lymphoblastique à cellules B CD22+ récidivante ou réfractaire ( BALLE)
This is a first-in-human, open-label, dose escalation and expansion study of UCART22 administered intravenously to patients with relapsed or refractory B-cell acute Lymphoblastic Leukemia (B-ALL). The purpose of this study is to determine the optimal dose of CLLS52 as part of the FCA LD regimen followed by the Recommended Phase 2 Dose (RP2D) of UCART22 and evaluate the safety and efficacy of UCART22.

Changes over time on quality of life using European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) (adults)
Délai: 24 months
|
EORTC QLQ-C30, a cancer-specific tool that assesses global health status, functional scales, and symptom burden. The questionnaire provides functional scores (physical, role, cognitive, emotional, and social), symptom scores (fatigue, nausea and vomiting, pain, dyspnoea, sleep disturbance, appetite loss, constipation, diarrhoea, and financial difficulties), and a global quality of life/health status score. Patients provide their responses on a 4-category rating scale for most of the items (not at all, a little, quite a bit, and very much), and on a 7-point numeric rating scale for the global items. Raw scores are converted into scale scores ranging from 0 to 100. For the functional scales and the global scale, higher scores represent better health-related quality of life (HRQoL); whereas for the symptom scales lower scores represent better HRQOL. |

Changes over time on quality of life using Pediatric Quality of Life Inventory (PedsQL) 4.0 (12-17 years)
Délai: Screening to 24 months
|
PedsQL 4.0 is a validated tool used to assess health-related quality of life in children and adolescents aged 12 to 17 years (for subjects aged 12 years the PedsQL-Child will be used, for participants aged 13-17 years the PedsQL-Teen will be used). It evaluates four key domains: physical functioning, emotional well-being, social interactions, and school performance. It includes 23 items, each item is rated on a 5-point scale, with scores ranging from 0 to 100. |
Screening to 24 months

Changes over time on quality of life using EuroQol 5-Dimension five-level (EQ-5D-5L)
Délai: 24 months
|
EQ-5D-5L, a self-administered, generic preference-based measure that enables health utility estimation for economic evaluation. The EQ-5D-5L includes single items such as mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Patients provide their response to each item using a 5-category rating scale (no problems, slight problems, moderate problems, severe problems, and extreme problems). Patient responses to the items are used to derive utility values for the calculation of Quality-Adjusted Life-Years in economic modelling in health technology assessment. The visual analog scale (VAS) item on the EQ-5D-5L asks patients to rate how good or bad their health is today. It is a vertical thermometer with the anchors "best imaginable health" at 100 and the "worst imaginable health" at 0. |
