Brief Summary:
This study will investigate the efficacy of ADP-A2M4CD8 T-cell therapy in subjects who have the appropriate human leukocyte antigen (HLA) and tumor antigen status and whose esophageal or esophagogastric junction (EGJ) cancer expresses the MAGE-A4 protein.

Arm Intervention/treatment
Experimental: Autologous genetically modified ADP-A2M4CD8 cells Genetic: Autologous genetically modified ADP-A2M4CD8 cells
Infusion of autologous genetically modified ADP-A2M4CD8 on Day 1




Primary Outcome Measures :
  1. Efficacy: Overall Response Rate (ORR) [ Time Frame: 2.5 Years ]
    ORR is defined as incidence of complete responses or partial responses as assessed by RECIST v1.1


Secondary Outcome Measures :
  1. Number of subjects with treatment -related adverse events (AEs), including serious adverse events (SAEs) as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 [ Time Frame: 2.5 years ]
    Determine if treatment with ADP-A2M4CD8 is safe and tolerable through assessment of adverse events (AEs) including Serious Adverse Events (SAEs)

  2. Efficacy: Best overall response (BOR) [ Time Frame: 2.5 Years ]
    Best Overall Response (BOR) is per RECIST V1.1.

  3. Time to response (TTR) [ Time Frame: 2.5 years ]
    For patients who are observed to respond to ADP-A2M4CD8, the time taken from date of infusion to achieve a partial response or complete response (TTR) is assessed.

  4. Duration of Response (DoR) [ Time Frame: 2.5 years ]
    For patients who are observed to respond to ADP-A2M4CD8, the DoR is the date of initial response (including confirmation) from date of infusion up until disease progression per RECIST v 1.1 or death.

  5. Progression Free Survival (PFS) [ Time Frame: 2.5 years ]
    PFS is assessed from date of infusion of ADP-A2M4CD8 up until the date of disease progression per RECIST v1.1 or death.

  6. Overall Survival (OS) [ Time Frame: 15 years ]
    OS is assessed from date of infusion of ADP-A2M4CD8 up until the date of patient death.

  7. Invitro diagnostic (IVD) assay for screening [ Time Frame: 2.5 years ]
    Development and validation of the MAGE-A4 antigen expression companion diagnostic assay

  8. Time taken to achieve peak expansion of genetically engineered T-cells in PBMCs [ Time Frame: 2.5 years ]
    Time taken to achieve peak expansion of genetically engineered T-cells in PBMCs by flow cytometry
