We are Developing Life-Changing Therapies Through the Use of Our Proprietary Technologies.

XCART Platform

XCART is a novel CAR T proximity-based screening platform capable of identifying CAR constructs that can target patient-specific tumor neoantigens, with a demonstrated proof of mechanism in B-cell Lymphomas. The XCART technology, developed by The Scripps Research Institute in collaboration with the Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry, is believed to have the potential to significantly enhance the safety and efficacy of cell therapy for B-cell Lymphomas by generating patient- and tumor-specific CAR T cells.

XBIO-101 (sodium cridanimod)

XBIO-101 is a small-molecule immunomodulator and interferon inducer which, in exploratory clinical studies, has also been shown to increase progesterone receptor (PrR) and estrogen receptor (ER) expression in certain tumor tissues. The Company plans to pursue collaborations with immuno-oncology (I-O) companies in which it would seek to use XBIO-101 in combination with approved or developmental I-O compounds such as checkpoint inhibitors.

PolyXen™

PolyXen is a patent-protected enabling platform technology designed for protein or peptide therapeutics. It uses the natural polymer polysialic acid (PSA) to prolong a drug's circulating half-life and potentially improve other pharmacological properties. PolyXen has been demonstrated in human clinical trials to confer extended half-life to biotherapeutics such as recombinant human erythropoietin (rhEPO) and recombinant Factor VIII (rFVIII).
