April 6, 2026 updated by: USWM CT, LLC

A Phase 1 Dose Escalation Study To Assess Safety And Efficacy Of ADP-A2M4CD8 As Monotherapy Or In Combination With Either Nivolumab Or Pembrolizumab In HLA-A2+ Subjects With MAGE-A4 Positive Tumors (SURPASS)

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.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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
2.5 years

Time Frame: 2.5 years
BOR is per RECIST V1.1.
2.5 years
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
2.5 years
Time to response (TTR)
Time Frame: 2.5 years
For 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.
2.5 years
Duration of Response (DOR)
Time Frame: 2.5 years
For 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
2.5 years
Progression Free Survival (PFS)
Time Frame: 2.5 years
PFS 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.
2.5 years
Overall Survival (OS)
Time Frame: 15 years
OS 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.
15 years
