We incorporate our patented and proprietary technologies into a number of drug candidates currently under development either in-house or with biotechnology and pharmaceutical collaborators in order to create what we believe will be the next-generation of biologic drugs and therapeutics. While we primarily focus on researching and developing orphan oncology drugs, we also have significant ownership or other economic interests in drugs being developed by our collaborators.
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 and recombinant Factor VIII (rFVIII).
XBIO-101 (sodium cridanimod)
XBIO-101 is a small-molecule immunomodulator and interferon inducer which, in preliminary studies, has been shown to increase progesterone receptor (PrR) expression in endometrial tissue. The Company has exclusive rights to develop and commercialize XBIO-101 worldwide, except for specified countries in the Commonwealth of Independent States, including Russia. XBIO-101 has been granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the potential treatment of progesterone receptor negative (PrR-) endometrial cancer in conjunction with progesterone therapy. XBIO-101 is currently being studied in an ongoing Phase 2 clinical trial. Patient enrollment for the Phase 2 trial commenced in June 2017.
- The primary objective of the open-label, multi-center, single-arm, two-period Phase 2 study is to assess the antitumor activity of XBIO-101 in conjunction with progestin therapy as measured by Overall Disease Control Rate in women with recurrent or persistent endometrial carcinoma not amenable to surgical treatment or radiotherapy who have either failed progestin monotherapy or who have been identified as PrR-. Secondary objectives include assessments of efficacy and safety/tolerability
The study is expected to enroll a total of 72 women with recurrent or persistent endometrial cancer not amenable to surgical treatment or radiotherapy but suitable to be treated with progestins. All subjects determined to be PrR- at screening, as well as those subjects who experience disease progression after at least 4 weeks of progestin monotherapy, will receive XBIO-101 in combination with continued progestin treatment. Subjects will receive treatment until disease progression as defined according to RECIST 1.1 criteria.
