Xenetic also provided a corporate update and anticipated milestones for the Company’s lead product candidate, XBIO-101 (sodium cridanimod), a small-molecule immunomodulator and interferon inducer which, in preliminary studies, has been shown to increase progesterone receptor ("PrR") expression in endometrial tumor tissue, and an update on its proprietary PolyXen platform technology.
Recent Corporate Highlights:
Appointed Jeffrey F. Eisenberg as Chief Executive Officer;
Entered into Right to Sublicense Agreement related to the Company’s PolyXen Technology with Baxalta Inc., a wholly-owned subsidiary of Shire plc; and
Commenced patient dosing in the Phase 2 clinical study of XBIO-101 in conjunction with progestin therapy for the treatment of endometrial cancer.
"I believe we are well positioned to build on the momentum of our recent corporate and clinical achievements. We remain focused on the solid execution of our Phase 2 study of XBIO-101 for the treatment of endometrial cancer, with the goal of announcing interim data before the end of next year. Further, our recent right to sublicense agreement with Baxalta not only leverages our PolyXen platform technology and provides a source of non-dilutive capital, but also positions Xenetic for value driving opportunities in the near and long-term," stated Jeffrey Eisenberg, Chief Executive Officer of Xenetic Biosciences.
XBIO-101 Program Update
Patient dosing recently commenced for the Company’s Phase 2 clinical study of XBIO-101 in conjunction with progestin therapy for the treatment of endometrial cancer. The study targets a population of patients who have either failed progestin monotherapy or who have been identified as having progesterone receptor negative ("PrR-") tumors.
The primary objective of this open-label, multi-center, single-arm, two-period Phase 2 study is to assess the anti-tumor 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 parameters.
The study is expected to enroll up to 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.
The Company expects to announce interim data from the Phase 2 study before the end of 2018.
PolyXen Platform Technology Update
The Company recently announced that it has entered into a Right to Sublicense Agreement (the "Right to Sublicense Agreement") with Baxalta Incorporated, Baxalta US Inc., and Baxalta GmbH (collectively, with their affiliates, "Baxalta"), wholly-owned subsidiaries of Shire plc (LSE: SHP, NASDAQ: SHPG). Pursuant to the Right to Sublicense Agreement, Xenetic granted to Baxalta the right to grant a nonexclusive sublicense to certain patents related to the Company’s PolyXen technology that were previously exclusively licensed to Baxalta pursuant to an agreement between the Company and Baxalta in connection with products relating to the treatment of blood and bleeding disorders.
As part of the Right to Sublicense Agreement, Baxalta paid Xenetic a one-time payment of $7.5 million and is expected to make single digit royalty payments based upon net sales of the products covered under the related sublicense throughout the term of the agreement.
Additionally, Xenetic expects to continue to pursue business development activities to explore partnerships utilizing its PolyXen delivery platform.
Summary of Financial Results for Third Quarter 2017
Net loss for the nine months ended September 30, 2017, was $8.0 million compared to a net loss of approximately $53.8 million for the same period in 2016. The decrease in net loss was primarily due to a decrease of in-process research and development expense, as well as a decrease in share-based compensation expense related to warrants previously issued in 2016. These decreases were offset by an increase in general operating costs and costs related to the initiation of our XBIO-101 Phase 2 clinical study.
The Company ended the quarter with approximately $0.7 million of cash. With the addition of the $7.5 million milestone payment under the Right to Sublicense Agreement, as of the date of this release, the Company’s current cash position is approximately $8.0 million. Based on management’s current projections, the Company has sufficient cash to fund its operations through the second quarter of 2018.
