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.

Lymphodepletion chemotherapy (fludarabine 30 mg/m2/day for 4 days and cyclophosphamide 600 mg/m2/day for 3 days) will be followed by infusion of 1â10x10^9 ADP-A2M4CD8 T-cells. Adverse events will be monitored, with participants followed for 15 years from T-cell infusion. Conclusion SURPASS-3 is initiating in Q2 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.

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.
