Journal: Phosphatidylserine (PS)-targeting chimeric Interferon (IFN) fusion proteins for anti-tumor applications. (Pubmed Central) - Feb 3, 2025 retain strong anti-tumor activities in a syngeneic model when expressed ectopically in a E0771 breast cancer model and B16-F10 melanoma models. Collectively, we report on the generation and utility of a series of novel in class IFN fusion proteins that target the immune stimulatory features of IFNs to the PS externalization in the tumor microenvironment.

P2 data, Clinical Trial,Phase II, Journal, PD(L)-1 Biomarker, IO biomarker: The phosphatidylserine targeting antibody bavituximab plus pembrolizumab in unresectable hepatocellular carcinoma: a phase 2 trial. (Pubmed Central) - Mar 16, 2024 P2 Prespecified exploratory analyses of baseline tumor specimens showed that a depletion of B cells, and the presence of fibrotic tissue and expression of immune checkpoints in stroma was associated with tumor response. These results suggest that targeting phosphatidylserine may lead to synergistic effects with PD-1 blockade without increasing toxicity rates, and future studies on this therapeutic strategy may be guided by biomarkers characterizing the pre-treatment tumor microenvironment.

Aberrantly exposed phosphatidylserine as a drug delivery target in pancreatic cancer (Section 3; Poster Board #23) - Mar 14, 2023 - Abstract #AACR2023AACR_4358; To this point, PS has been targeted with antibodies, such as Bavituximab, that have shown excellent specificity for tumor vasculature and an immune stimulatory environment evidence by polarization of macrophages to a pro-inflammatory M1-like phenotype, a reduction in myeloid-derived suppressor cells, enhanced maturation of dendritic cells and increased primed T cell activity...The mechanism of action has not yet been fully elucidated; however, it may involve the interaction between the ?2GP1 domains and endogenous LPS. This first-in-class tumor targeting therapeutic has potential to provide efficacy in therapy-resistant pancreatic tumors via targeted drug delivery as well as modulation of the immuno-microenvironment like its PS targeting predecessors.

Biomarker, Review, Journal: Phosphatidylserine: The Unique Dual-Role Biomarker for Cancer Imaging and Therapy. (Pubmed Central) - May 30, 2022 Recent studies have demonstrated that upregulation of surface PS exposure by chemodrugs, radiation, and external electric fields can be used as a novel approach to sensitize cancer cells to PS-targeting anticancer drugs. The objectives of this review are to provide an overview of a unique dual-role of PS as a biomarker/target for cancer imaging and therapy, and to discuss PS-based anticancer strategies that are currently under active development.

Journal: Phosphatidylserine-Targeting Monoclonal Antibodies Exhibit Distinct Biochemical and Cellular Effects on Anti-CD3/CD28-Stimulated T Cell IFN-γ and TNF-α Production. (Pubmed Central) - Oct 27, 2021 Using human T cells from healthy donor PBMCs activated with an anti-CD3 + anti-CD28 Ab mixture (anti-CD3/CD28) as a model for TCR-mediated PS externalization and T cell stimulation, we investigated effects of two different PS-targeting mAbs, 11.31 and bavituximab (Bavi), on TCR activation and TCR-mediated cytokine production in an ex vivo paradigm...Imaging showed 11.31 and Bavi bind at distinct focal depots on the cell membrane. Collectively, our findings indicate that PS-targeting mAb 11.31 suppresses cytokine production by anti-CD3/28 activated T cells.

Our studies may inform the design of clinical trials combining PS Targeting antibodies with CAR T cell therapy in solid tumors.
