Experimental: Part 1: Dose Escalation
Several tested doses of UCART123v1.2 with different lymphodepletion regimens to establish Maximum Tolerated Dose (MTD) and identify Recommended Phase 2 Dose (RP2D) Dose Expansion: UCART123v1.2 administered at the selected dose determined from the dose escalation phase |
Biological: UCART123v1.2
Allogeneic engineered T-cells expressing anti-CD123 Chimeric Antigen Receptor |
- Incidence of AE/SAE/DLT [Safety and Tolerability] [ Time Frame: 24 Months ]Safety of UCART123v1.2 - Incidence, nature, and severity of adverse events and serious adverse events (SAEs) throughout the study
- Response Assessment [ Time Frame: At Day 28, Day 56, Day 84, Month 3, Month 6, Month 9, Month 12, Month 15, Month 18, Month 21 and Month 24 ]
- Duration of Response [ Time Frame: From the date of the initial response to the date of disease progression or death from any cause, whichever occurs first, assessed up to Month 24 ]
- Progression Free Survival [ Time Frame: From the first day of study treatment to the date of disease progression or death from any cause, whichever occurs first, assessed up to Month 24 ]
- Overall Survival [ Time Frame: From the first day of study treatment to the date of death from any cause, assessed up to Month 24 ]
