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 MAGE-A4 tumor antigen. Tumor indications include endometrial, esophageal, esophagogastric junction (EGJ), gastric, head and neck, melanoma, non-small cell lung (NSCLC), ovarian or urothelial cancer.

Design outcomes

Primary

MeasureTime frameDescription
To evaluate safety and tolerability of ADP-A2M4CD8 as monotherapy or in combination with either nivolumab or pembrolizumab2.5 yearsDetermination of incidence of dose-limiting toxicities, adverse events and tolerable dose
To evaluate safety of ADP-A2M4CD8 as monotherapy or in combination with either nivolumab or pembrolizumabUp to 15 yearsIncidence of patients with Replication-competent Retrovirus, persistence of ADP-A2M4CD8 T-cells and incidence of insertional oncogenesis.

Secondary

MeasureTime frameDescription
Duration of Response (DOR)2.5 yearsFor patients who are observed to respond to ADP-A2M4CD8 as monotherapy or in combination with either nivolumab or pembrolizumab, the DOR is the date of first response (including confirmation) up until disease progression per RECIST v 1.1 or death
Duration of stable disease (DoSD)2.5 yearsFor 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
Anti-tumor activity: Best overall response (BOR)2.5 yearsBOR is per RECIST V1.1.
Overall Survival (OS)15 yearsOS is assessed from date of infusion of ADP-A2M4CD8 as monotherapy or in combination with either nivolumab or pembrolizumab up until the date of patient death.
Anti-tumour activity: Overall Response Rate (ORR)2.5 yearsORR is defined as incidence of complete responses or partial responses as assessed by RECIST v1.1
Progression Free Survival (PFS)2.5 yearsPFS is assessed from date of infusion of ADP-A2M4CD8 as monotherapy or in combination with either nivolumab or pembrolizumab up until the date of disease progression per RECIST v1.1 or death.
Time to response (TTR)2.5 yearsFor patients who are observed to respond to ADP-A2M4CD8 as monotherapy or in combination with either nivolumab or pembrolizumab, the time taken to achieve a partial response or complete response (TTR) is assessed.
