Brief Summary:
This study will investigate the safety and tolerability of ADP-A2M4CD8 T-cell therapy in subjects who have the appropriate human leukocyte antigen (HLA) and tumor antigen status and whose urothelial, head and neck, gastric (stomach), esophagogastric junction (EGJ), non-small cell lung (NSCLC), esophageal or ovarian cancer that express the MAGE-A4 protein.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 60 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1 Dose Escalation Study To Assess Safety And Efficacy Of ADP-A2M4CD8 In HLA-A2+ Subjects With MAGE-A4 Positive Tumors
Actual Study Start Date : August 20, 2019
Estimated Primary Completion Date : September 30, 2023
Estimated Study Completion Date : April 30, 2037

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. 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. Evaluate safety of ADP-A2M4CD8 through measurement of Replication -competent Retrovirus in genetically engineered T-cells [ Time Frame: 15 years ]
    Evaluation of RCL using PCR -based assay in peripheral blood.

Secondary Outcome Measures :
  1. Anti-tumour activity: 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

  2. Anti-tumor activity: Best overall response (BOR) [ Time Frame: 2.5 years ]
    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. Duration of stable disease (DoSD) [ Time Frame: 2.5 years ]
    For patients who are observed to have stable disease by RECIST v 1.1, the duration of period of stable disease until disease progression or death

  6. 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.

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