The primary tumor cohort showed no association between NY-ESO-1 expression and OS (including stratification by HLA-A∗02 subtype and treatment line), when adjusting for important prognostic factors, possibly due to small sample sizes.

Our immunoassay of NY-ESO-1/XAGE1 Abs is probably useful for predicting the clinical benefit with nivolumab in NSCLC, including those harboring driver genes. These results suggest that our immunoassay may be useful in ICI monotherapy for NSCLC.

BNT111, an investigational lipoplex-formulated mRNA-based therapeutic cancer vaccine encoding melanoma TAAs NY-ESO-1, tyrosinase, MAGE-A3, and TPTE, is undergoing clinical testing in adults. All four TAAs were expressed in pediatric melanoma, albeit NY-ESO-1 and MAGE-A3 to a lesser extent than in adult melanoma. These data support the possibility of investigating vaccines targeting these TAAs for the treatment of pediatric melanoma.

We also found that the in vitro activity of IgG-T-TCE-NY could be leveraged by various anti-CD3 antibodies and Fc silencing. The IgG-T-TCE-NY efficiently inhibited tumor growth in a tumor-PBMC co-engrafted mouse model without any obvious toxicities.

The combination of NY-ESO-1 and p53 antibody responses to CEA and CA19-9 increases the diagnostic accuracy of gastric cancer. Serum NY-ESO-1 and p53 antibodies may be useful tumor markers for gastric cancer.

These findings indicate that the HSP70/NY-ESO-1 p86-94 may significantly enhance CTLs-mediated cytotoxicity and targeting ability against NY-ESO-1-expressing tumors in vitro. 5-Aza-CdR treatment with HSP70 binding to tumor antigen is a new strategy for immunotherapy of the tumors with poor CTA expression.

Our findings suggest that dual-targeted immunotherapy may have a superior antitumor effect. Our study presents a technique to evolve novel, robust, timely therapeutic strategies and interventions for EC and other malignancies.

Serum NY-ESO-1 antibodies may be a useful predictive marker for postoperative recurrence in gastric cancer.

C-MET and NY-ESO1 do not have any clinical correlations. EGFR can potentially serve as target in future clinical immune therapy trials.

No significant difference in NY-ESO-1 expression in primary tumors was observed concerning lymph node metastasis status. In summary, our findings suggest that increased expression of NY-ESO-1 could potentially serve as a prognostic biomarker for gastric cancer.

Furthermore, experimental results have also demonstrated the repeatability of the proposed biosensor. This proposed biosensor features label-free, compactness, and fast response, which could be potentially applied in the diagnosis of esophageal cancer.

Previous work from our group has shown that Decitabine (DAC), a demethylating agent, can improve the immunogenicity of Glioblastoma (GBM) for immuno-therapeutic targeting through the upregulation of immunogenic cancer testis antigens (CTA) such as NY-ESO-1 and altered expression of other immunoregulatory programs... Our results demonstrate a preclinical rationale for the use of GSK as a viable pro-antigenic agent for the sensitization of GBM to targeted immune therapy.

Hypomethylating agents like DAC upregulate immunogenic signatures in primary and immortalized GBM cells, rendering them susceptible to antigen specific T-cell targeting. These pleiotropic effects demonstrate strong preclinical rationale for use of DAC to sensitize GBM for targeting by immune therapies.

Background: Patients with intermediate and higher-risk MDS are generally treated with the DNA hypomethylating agents (HMAs) azacytidine and decitabine...This open-label, non-randomized single center Phase 1 study used an HLA unrestricted NY-ESO-1 vaccine (CDX-1401 (1 mg) + poly-ICLC (1.8 mg)) in combination with standard dose decitabine (20mg/m2/d x 5 days) and nivolumab (3 mg/kg every 2 weeks), 4 cycles of combination therapy were planned on study; patients deriving clinical benefit could continue treatment at the discretion of the treating physician... These results suggest that the use of immunotherapy to induce effective, cytotoxic anti-tumor T cell responses depends upon the myeloid immunologic milieu in MDS patients. The critical importance of cDC1 function has recently been described and appreciated in the context of solid tumor immunotherapy. The observation of both numerical and functional defects of this cell population in patients with myeloid neoplasia provides a possible explanation for the disappointing efficacy of immunotherapies in this disease state.

Our findings underscore the specific targeting potential of engineered TCR T cells against NY-ESO-1-positive tumors. Further comprehensive in vivo investigations are essential to thoroughly validate these results and effectively harness the intrinsic potential of genetically engineered T cells for combating cancer.

From cancer vaccines to engineered cellular therapy approaches, a multitude of immunotherapies targeting CTA's are coming to the forefront of oncology. Although the efficacy of such approaches have yet to provide convincing evidence of durable response, early phase clinical trial data has resulted in some exciting findings which will have significant potential to act as a platform for future practice changing technologies.

Adoptive immunotherapy with TBI-1301 to selectively target NY-ESO-1 positive tumor cells appears to be a promising strategy for the treatment of advanced or recurrent synovial sarcoma with acceptable toxicity.
