Open-Label Pilot Study of Genetically Engineered NY-ESO-1 Specific T Cells (GSK3377794) Alone or in Combination with Pembrolizumab in Relapsed and Refractory Multiple Myeloma
NY-ESO-1 TCR T (GSK3377794) are autologous polyclonal T cells transduced by a self-inactivating lentiviral vector to express an affinity-enhanced TCR recognizing NY-ESO-1 or LAGE-1a antigenic peptides in complex with HLA-A2. NY-ESO-1 and LAGE-1a are immunogenic cancer/testis antigens overexpressed in mutiple myeloma (MM) and linked to poor clinical outcome. Patients (pts) with MM who received GSK3377794 after autologous stem cell transplant (ASCT) showed encouraging clinical activity. PD-1 expression on CD8 T cells can occur in GSK3377794-treated MM pts and may limit adaptive immune response; this is a mechanism of resistance/relapse in CD19 CAR T-cell trials.
