Abstract:
The regulatory approvals of tumor-agnostic therapies have led to the re-evaluation of the drug development process. The conventional models of drug development are histology-based. On the other hand, the tumor-agnostic drug development of a new drug (or combination) focuses on targeting a common genomic biomarker in multiple cancers, regardless of histology. The basket-like clinical trials with multiple cohorts allow clinicians to evaluate pan-cancer efficacy and toxicity. There are currently eight tumor agnostic approvals granted by the Food and Drug Administration (FDA). This includes two im

Abstract:
Abstract Introduction: Plasma-derived cell-free DNA (cfDNA) can be used to identify cancer signals, including minimal residual disease (MRD), in patients who have undergone curative cancer treatments. The cell-free methylated DNA immunoprecipitation and high-throughput sequencing (cfMeDIP-seq) methodology is combined with custom algorithms that leverage differentially methylated regions (DMRs) found in cfDNA to distinguish between cancer and non-cancer signals. This novel non-degradative, tissue-agnostic approach was developed to bypass the limitations of bisulfite-sequencing and tissue-inform

Bria-IMT is an irradiated allogeneic BC cell line that has been engineered to secrete GM-CSF and may function as antigen-presenting cells. Bria-IMT antigens are taken up by dendritic cells and presented to T cells, generating a tumor-directed immune response.

Abstract:
Abstract 4-1BB (CD137, TNFRSF9) is a potent co-stimulatory receptor found on T and NK cells. Activation of 4-1BB requires receptor clustering, which is naturally mediated by the endogenous trimeric 4-1BB ligand. Cross-linking via agnostic monoclonal antibodies can also activate 4-1BB but has generally resulted in unwanted side effects, mainly liver toxicity. To address the shortcomings of 4-1BB agonists, we have developed QL301, a PD-L1 x 4-1BB bispecific antibody that conditionally activates 4-1BB only when concurrently engaged to PD-L1, an immune checkpoint mediator elevated in the immuno-su

Such approaches can be a limitation in IO drug discovery since the development of de novo antibodies is associated with long lead times, high costs, and high failure rates, often resulting in the substitution of the prote

Here, we designed immunocytokines with antibodies specific for the invariant linker peptides that join variable domains in the CAR scFv and immunostimulatory cytokines.
