MAGE-A4ᶜ¹º³²T for Multi-Tumor

April 15, 2026 updated by: USWM CT, LLC

Phase 1 Dose Escalation, Multi-tumor Study to Assess the Safety, Tolerability and Antitumor Activity of Genetically Engineered MAGE-A4ᶜ¹º³²T in HLA-A2+ Subjects With MAGE-A4 Positive Tumors

This study will investigate the safety and tolerability of MAGE-A4ᶜ¹º³²T cell therapy in subjects who have the appropriate HLA-A2 tissue marker and whose urinary bladder, melanoma, head and neck, ovarian, non-small cell lung, esophageal, gastric, synovial sarcoma, or myxoid/round call liposarcoma (MRCLS) tumor has the MAGE-A4 protein expressed. This study will take a subject's T cells and give them a T cell receptor protein that recognizes and attacks the tumors. This study has a substudy component that will investigate the safety and tolerability of MAGE-A4c1032T cell therapy in combination with low dose radiation in up to 10 subjects.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Adverse Events (AE) Including Serious Adverse Events (SAE)
Time Frame: From the start of lymphodepleting chemotherapy until end of interventional phase (up to 3.2 years).
An AE was defined as any untoward medical occurrence in a clinical study participant who received a pharmaceutical product, regardless of causality. An AE was , therefore, any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants with AEs (including SAEs) are presented.
From the start of lymphodepleting chemotherapy until end of interventional phase (up to 3.2 years).
Peak Persistence
Time Frame: From afamitresgene autoleucel infusion up to 18 months post-infusion
Peak persistence of afamitresgene autoleucel cells was reported as vector copy numbers per microgram of genomic DNA from peripheral blood mononuclear cell (PBMC).
From afamitresgene autoleucel infusion up to 18 months post-infusion
Replication Competent Lentivirus (RCL)
Time Frame: From afamitresgene autoleucel infusion to 3 months post-infusion
The presence of RCL was assessed by quantitative polymerase chain reaction (qPCR) targeting a segment of the vesicular stomatitis virus glycoprotein (VSV-G) coding sequence.
From afamitresgene autoleucel infusion to 3 months post-infusion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Response Rate (ORR)
Time Frame: From afamitresgene autoleucel infusion until disease progression/recurrence (up to 3.2 years)
ORR, defined as the proportion of participants with Best Overall Response (BOR) of confirmed completed response (CR) or partial response (PR) among participants with measurable disease at Baseline. The ORR was based on the assessment of response per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 by local radiologist. Participants with unknown or missing response were treated as non-responders.
From afamitresgene autoleucel infusion until disease progression/recurrence (up to 3.2 years)
Best Overall Response (BOR)
Time Frame: From afamitresgene autoleucel infusion until disease progression/recurrence (up to 3.2 years)
BOR was defined as the best response recorded from the date of T-cell infusion until disease progression. Response categories from best to worst were, confirmed CR, confirmed PR, stable disease (SD), progressive disease (PD), and not evaluable (NE) (per RECIST v1.1)
From afamitresgene autoleucel infusion until disease progression/recurrence (up to 3.2 years)
Time to Response (TTR)
Time Frame: From afamitresgene autoleucel infusion until first documented confirmed CR or PR
TTR was defined as the interval between the date of the first T-cell infusion and the earliest date of the first documented confirmed CR or confirmed PR.
From afamitresgene autoleucel infusion until first documented confirmed CR or PR
Duration of Response (DoR)
Time Frame: From initial confirmed response (DR or PR) until PD or censored date. is defined as all participants who had not experienced the event of interest (i.e. ongoing, event free) at the time of the data cut off (used for the analysis).
DoR was measured from the first CR/PR (whichever was first recorded) until the first date of progressive disease.
From initial confirmed response (DR or PR) until PD or censored date. is defined as all participants who had not experienced the event of interest (i.e. ongoing, event free) at the time of the data cut off (used for the analysis).
Duration of Stable Disease (DoSD)
Time Frame: From date of afamitresgene autoleucel infusion to first date of radiological PD or censored date
DoSD was defined as the time from the date of T-cell infusion to the first date of the radiological PD. This analysis of DoSD only applied to participants with BOR as confirmed CR, confirmed PR, or confirmed SD.
From date of afamitresgene autoleucel infusion to first date of radiological PD or censored date
Progression Free Survival (PFS)
Time Frame: From afamitresgene autoleucel infusion until first documented PD or death due to any cause, whichever comes first, or censored date.
PFS was defined as the time from the date of the first T-cell infusion to the first date of the radiological PD or death date (due to any reason), whichever event was earlier.
From afamitresgene autoleucel infusion until first documented PD or death due to any cause, whichever comes first, or censored date.
Overall Survival (OS)
Time Frame: From afamitresgene autoleucel infusion until death due to any reason or censored date From afamitresgene autoleucel infusion until death due to any reason or censored date
OS was defined as the time from the date of afamitresgene autoleucel infusion to the date of death (due to any reason).
From afamitresgene autoleucel infusion until death due to any reason or censored date From afamitresgene autoleucel infusion until death due to any reason or censored date

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
