Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum Tolerated Dose (MTD)	A standard 3+3 trial design will be used for Welgenaleucel (UWC19) dose escalation cohorts.The dosing of Welgenaleucel (UWC19) will be divided into 5 cohorts, the subjects will receive Welgenaleucel (UWC19) once on day 14-18 after apheresis.	30 days after infusion
Primary	Dose Limiting Toxicities (DLT)	The 3+3 design entails that if one patient out of the first three patients has a DLT, up to three additional patients will be entered at that dose level.	30 days after infusion
