CTAG2 (Cancer/testis antigen 2)

IMCnyeso is well tolerated and, at doses ≥30 μg, induces pharmacodynamic changes consistent with T cell redirection. This study was registered at ClinicalTrials.gov (NCT03515551).

Extensive HLA-A*02 and antigen expression testing was performed to identify potential participants. Lete-cel was generally well tolerated and had no unexpected AEs. Anti-tumor activity was observed in a limited number of patients.

Additionally, TCR-T cells that target multiple antigens in the same cancer yield better anticancer activity than those targeting a single antigen. This showed that targeting multiple antigens with a common epitope may enhance the antitumor response efficacy of T cell therapies.

Further exploration uncovered that the expressions of several important genes closely related to metabolic pathways in CRC were noticeably altered due to PLD2 deficiency, including ID1, IFIT4, OASL, IFIT2 and CTAG2. Our results revealed that PLD2 deficiency promotes cell invasion and metastasis in CRC via EMT indicating PLD2 might have an important implication in carcinogenesis and progression and would be a new therapeutic target for cancer treatment.

We have identified an 8 HPV-RNA signature associated with the prognosis of SCCHN patients. Such prognostic model might serve as possible candidate biomarker and therapeutic target for SCCHN.

This is the first report of comprehensive AAb profiling of patients with mUC and identified key AAbs that were elevated in patients with mUC versus HCs as well as AAbs associated with therapeutic response to ICI. These findings are hypothesis generating and further mechanistic studies evaluating humoral immunity in UC are required.

NGS revealed potentially actionable targets in half of sarcoma patients based on ESCAT criteria. With ongoing accrual and sequencing of additional tumor specimens future analysis of the CAUSAL cohort will focus on assessing the correlation between targetable mutations and clinical outcomes.

Methods Two first-in-class, 3rd generation TCR-T therapies, MDG1015 and MDG2011, were developed using optimal affinity TCRs specific for a cancer-testis antigen, NY-ESO-1/LAGE-1a, and a neoantigen, mutated KRAS G12V, respectively. Conclusions The combination of optimal affinity TCRs combined with the PD1-41BB CSP provides strong protection of TCR-T cells against two variable mechanisms of TME immunosuppression based on the demonstration of CSP-enhanced poly-cytokine secretion, proliferation and mitigation against exhaustion in vitro. This observation warrants application in the clinic for this novel approach to potentially overcome the major challenges in solid tumor TMEs.
