    ATTAC-MCC: Phase I/II study of autologous CD8+ and CD4+ transgenic T cells expressing a high affinity MCPyV-specific TCR combined with checkpoint inhibitors and class I MHC-upregulation in patients with metastatic MCC refractory to PD-1 axis blockade. (ASCO 2022)
    NCT03747484 is an ongoing phase I/II, open label, investigator-initiated trial (IIT) of FH-MCVA2TCR in combination with an anti-PD-(L)1 checkpoint inhibitor and an agent to upregulate MHC-I expression on tumor cells...Secondary/exploratory objectives include cellular kinetics of TCR T cells, T cell phenotype, tumor infiltration kinetics, and MHC-I expression dynamics over time. After the first 12 months, patients transition to a long-term follow-up (LTFU) study for up to 15 years as per FDA guidelines.
