Clinical and translational data from the phase I SURPASS trial of ADP-A2M4CD8 T cell receptor (TCR) T cell therapy alone or combined with nivolumab in solid tumors (ESMO 2023)
Nevertheless, inhibition of immunosuppressive pathways may improve anti-tumor responses; therefore, new SURPASS cohorts include ADP-A2M4CD8 combined with nivolumab or pembrolizumab. Data from additional pts treated by August 2023 will be presented. Conclusions ADP-A2M4CD8 continues to show an acceptable benefit-to-risk profile, including in pts receiving nivolumab combination therapy.

Modulation of Single-Cell Gene Expression and Cell Function in Evolving Manufacturing Processes for Clinical Trials with Enhanced-Affinity T-Cell Receptor T-Cell Therapy Targeting the MAGE-A4 Antigen in Solid Tumors (ASGCT 2023)
Introduction: Affinity-enhanced T-cell receptor (TCR) T-cell therapies targeting the intracellular cancer testis antigen MAGE-A4 have shown encouraging results in adults with advanced solid cancers.1,2 Here we explore how TCR T-cell therapy manufacturing process evolution may modulate the function of ADP-A2M4CD8, the next generation counterpart of afamitresgene autoleucel (afami-cel; formerly ADP-A2M4), using single-cell RNA sequencing (scRNA-seq) and in vitro functional assessment. Whole-transcriptome, single-cell investigation of the cellular subsets produced during manufacturing of afami-cel and ADP-A2M4CD8 indicate that infusion of cells with a less cytotoxic GEP does not prevent broad anti-tumor efficacy and may correspond with beneficial characteristics. 1.

Increasing the Awareness of Nurses on Evolving Cell Therapies (ONS 2023)
Purpose: This abstract presents data on two cell therapies being tested in clinical trials, afamitresgene autoleucel (afami-cel; formerly ADP-A2M4) and its next-generation counterpart ADP-A2M4CD8, to inform nurses on new promising therapies...SURPASS (NCT04044859) is a Phase 1, first-in-human trial evaluating ADP-A2M4CD8 as monotherapy or in combination with nivolumab in multiple tumor types... Nurses play key roles at every stage in the administration of T-cell therapy. Understanding advances in cancer treatment and associated clinical data will better prepare nurses to effectively manage patients that may benefit from these novel therapies.

Enhancement of TCR-engineered T-cells targeting MAGE-A4 antigen by co-expression of CD8α and inhibition of AKT signaling during ex vivo T-cell expansion (SITC 2021)
scRNASeq gene expression profiles of first-gen ADP-A2M4 product manufactured with AKTi revealed the AKTi-expanded T-cells had a greater proliferation or an enhanced memory phenotype; scRNASeq analyses are ongoing for the ADP-A2M4CD8 product.An increase in IL-12 levels (MSD) in serum post-infusion suggests that endogenous immune cells are being activated, further resulting in increased levels of IFN gamma (MSD) secretion relative to patients who received first-gen product. These enhanced products improve CD4+ T-cell killing, release more inflammatory cytokines, proliferate more robustly with an early memory phenotype, and better engage the patient‘s endogenous immune system when compared to first-gen products or next-gen manufactured without AKTi.

[VIRTUAL] Safety and efficacy from the SURPASS trial with ADP-A2M4CD8, a SPEAR T-cell therapy incorporating a CD8α co-receptor and an affinity optimized TCR targeting MAGE-A4 (ESMO 2021)
Prior to infusion, pts receive lymphodepletion with fludarabine 30 mg/m2/day for 4 days and cyclophosphamide 600 mg/m2/day for 3 days. ADP-A2M4CD8 SPEAR T-cells have shown an acceptable safety profile. Emerging efficacy data remain encouraging with the majority of pts experiencing disease control and RECIST responses in several solid tumor types. A full update will be presented at the conference.

[VIRTUAL] Initial safety, efficacy, and product attributes from the SURPASS trial with ADP-A2M4CD8, a SPEAR T-cell therapy incorporating an affinity optimized TCR targeting MAGE-A4 and a CD8α co-receptor (SITC 2020)
Prior to infusion, pts receive lymphodepletion with fludarabine 30 mg/m2/day for 4 days and cyclophosphamide 600 mg/m2/day for 3 days. Results As of 16 July 2020, 5 pts (1 with MRCLS, 2 with esophagogastric junction [EGJ] cancers, 1 with ovarian cancer, and 1 with head and neck cancer) were treated with ADP-A2M4 CD8 (range ~1 to 5.7 billion transduced cells)...Translational data and early clinical results indicate that co-expression of the CD8α co-receptor on CD4+ SPEAR T-cells may increase the potency of the product by conferring additional killing activity to the helper T-cell subset. This dose escalation trial is ongoing and updated clinical and translational data will be presented.
