Trial primary completion date, CAR T-Cell Therapy: Autologous CD19 CAR-T Cell Therapy (SYNCAR-001) + Orthogonal IL-2 (STK-009) in Subjects With CD19+ Hematologic Malignancies (clinicaltrials.gov) - Feb 20, 2024 P1, N=36, Recruiting, signaling induces a superior synthetic effector state via transcriptional repression of the stress response/proteosome.These findings support the advantages of an orthogonal platform that selectively drives and sustains potent T cell effector function without safety concerns associated with constitutively expressed armored approaches. Trial primary completion date: Jun 2024 --> Jun 2026

Engineered human IL-2/IL-2R (Exhibit Hall B) - Sep 27, 2023 - Abstract #SITC2023SITC_596; P1 Importantly, STK-009 induced the expression of cytotoxic machinery, pro-survival, and proliferative genes in tumor-infiltrating SYNCAR-002 (figure 3). Conclusions These findings validate that the orthogonal IL-2 platform has the potential to improve the efficacy and durability of CAR T therapy for solid tumor targets such as GPC3 by selectively expanding CAR-T cells in vivo and activating CAR-T cells in a hostile tumor microenvironment.

Engineered human IL-2/IL-2Rb orthogonal pairs selectively enhance anti-GPC3 CAR T cells to drive complete responses in solid epithelial tumor models (Section 35) - Mar 9, 2022 - Abstract #AACR2022AACR_4766; STK-009 treatment resulted in significant expansion of SYNCAR-002 and drove infiltration of SYNCAR-002 into tumors. STK-009 treatment also induced intratumoral granzyme B+ and IFN-γ+ production by SYNCAR-002 indicating activation of effector T cell function.These findings validate that the orthogonal IL-2 platform has the potential to improve the efficacy and durability of CAR T therapy for solid tumor targets such as GPC3 by selectively expanding CAR-T cells in vivo, driving CAR-T cells into the tumor, and activating CAR-T cells in the tumor microenvironment.
