    الوصف: Background To address the heterogeneity of response to therapies, the oncology field is moving toward precision medicine (PM), with therapy tailored to a patient‘s disease. Biomarker assessment is now critical when screening for enrollment into clinical studies, such as for T-cell receptor therapies and combination studies, and determining status of a single analyte does not always correlate to clinical benefit. 1 This shift may increase enrollment screen-failure rates due to restrictive eligibility criteria (e.g., biomarker prevalence). For oncology patients, the need for timely treatment does not allow for a sequential, complex, and time-consuming screening process for each individual clinical trial. The design and data from studies such as Lung MAP have emphasized a need to change clinical trial screening. As we begin to target less common genomic and immunotherapy subtypes, comprehensive molecular characterization may lead to rapid delivery of therapies to patients while maximizing the quality of data. 2 The Molecular Disease Characterization Initiative (MDCI; GlaxoSmithKline Study 213299 [ NCT04772053 ]) screens for multiple studies at once by collecting a baseline assessment of disease prior to treatment with different therapeutic modalities, and evaluating the patient‘s tumor and blood genetics. The MDCI creates a platform to accelerate the availability of new therapeutic options for patients through matched investigative and PM clinical trials, while building a scientific database to facilitate the investigation of biological mechanisms underpinning clinical outcomes. Methods This multicenter study enrolls patients (N= 400) with advanced/metastatic malignancies, initially non-small cell lung cancer, to collect biospecimens for broad molecular profiling and examining the expression of specific antigens (e.g. NY-ESO-1, LAGE-1a), immune markers (e.g. ICOS, PD-L1), tumor-infiltrating immune cells, differentially expressed genes, and human leukocyte antigen (HLA). In this single-arm, non-interventional, ...

    الوصف: Myeloid-derived suppressor cells (MDSC) are one of the major negative regulators of immune responses in cancer closely associated with negative outcome of PD1 therapy in metastatic melanoma. TRAIL-R DR5 is selectively up- regulated on MDSC. The goal of this study is to test the hypothesis that agonistic TRAIL-DR5 antibody DS-8273a will be well tolerated and augment the clinical efficacy of PD-1 blocking antibody nivolumab by impacting on MDSC. DS-8372a at low doses (4 and 8 mg/kg) was well tolerated with 2 excellent responses in 6 patients and one mixed response; it did not affect populations of MDSC or other myeloid and lymphoid cells, but monocytic MDSC function was augmented. In the first 4 patients we evaluated the response of T cells to melanoma derived pool of overlapping peptides in IFN- ELISPOT assay. In one patient we observed substantial increase in the response to peptides after 3 cycles of treatment. These results are preliminary. Moreover, the dose of antibody was very low to expect substantial responses. We anticipate that next two doses (16 mg/kg and24 mg/kg) with escalation occurring early in October will provide more clear data.
