Xenetic Biosciences CEO Delivers "2014 - The Year in Review" Update to Investors and StakeholdersXenetic Biosciences, Inc. (OTCBB:XBIO), a biopharmaceutical company focused on developing next-generation biologic drugs and novel oncology therapeutics, announces that CEO M. Scott Maguire has written a Letter to Shareholders, the full text of which appears below: To Our Shareholders: The year 2014 at Xenetic Biosciences has been defined by a number of significant achievements. As I review all the activities of the past year I am, quite frankly, extremely excited and proud to share with you our considerable accomplishments and to review our plans to build upon that momentum in 2015. Key highlights of 2014 included:
PolyXen technology As you know, PolyXen® is our proprietary enabling platform technology for protein drug delivery. It uses the natural polymer polysialic acid (PSA) to prolong a drug's half-life and potentially improve the stability of therapeutic peptides and proteins. Multiple therapeutics incorporating this technology are currently being studied for several different indications. We call these therapeutics "biobetters" as they represent an improvement over current biologic drugs. PolyXen is a next-generation approach to the widely marketed PEGylation delivery technology. We believe that PolyXen offers many advantages including greater versatility, biogradeability and broader patent coverage. During 2014 we made excellent progress in developing EropoXen,® a polysialylated form of recombinant human erythropoietin (EPO), which is a hormone produced by the kidneys to maintain red blood cell production and prevent anemia. Chronic renal failure or chemotherapy can cause anemia. ErepoXen is a polysialylated form of EPO designed to reduce the frequency of dosage and side effects compared with existing treatments, and to be less immunogenic. The annual worldwide market for anemia therapies is estimated to be $7.2 billion. EropoXen is the subject of several ongoing safety, efficacy and tolerability studies.
We announced positive results from a Phase 1 clinical trial of PSA-Oxyntomodulin for the treatment of type 2 diabetes and obesity, which also was conducted in Russia by OJSC Pharmsynthez. In this single-center, randomized, placebo-controlled trial PSA-Oxyntomodulin was administered once to 12 healthy volunteers subcutaneously at one of three different dose levels (0.25, 0.75 and 1.5 mg/kg) with a placebo administration in each cohort. PSA-Oxyntomodulin was found to be well tolerated in all patients at all doses tested. We continue to work with Baxter International to develop novel, longer-acting forms of polysialylated blood coagulation factors using Xenetic's technology to conjugate PSA to therapeutic blood-clotting factors. This work includes Factor VIII, a multibillion-dollar drug for treating hemophilia. The goal of the program is to improve the pharmacokinetic profile and extend the active life of these factors to once-a-week administration as opposed to the drugs currently on the market that are delivered two to five times a week. As noted above, we were very pleased to receive a direct investment of $10 million from Baxter in conjunction with an amended license agreement, which included increased contingent milestone payments totaling potentially up to $100 million, as well as higher royalties on sales. OncoHist™ One of the world's most prominent leaders in hematological cancers, Richard M. Stone, M.D., presented an abstract at ASH on preclinical work with OncoHist in acute myeloid leukemia (AML) cells. The abstract concluded that the research supported the development of OncoHist alone and in combination with chemotherapy for the treatment of AML. We are very excited about this research and with our affiliation with Dr. Stone, who is Director of the Adult Acute Leukemia Program at Dana-Farber Cancer Institute and Professor, Department of Medicine, Harvard Medical School. He also serves on the Medical Oncology Board of the American Board of Internal Medicine and is Chair, Alliance Leukemia Committee. We are preparing to enter human clinical trials in the U.S. with OncoHist in 2015 for the treatment of refractory AML, based on research by Dr. Stone and his colleagues through our agreement with Dana-Farber. Notably, AML has the lowest survival rate of all leukemias. ImuXen® technology ImuXen® is our patented platform technology based on the concept of simultaneous delivery of multiple active pharmaceutical ingredients (APIs) as antigens within the same liposome. MyeloXen™ uses this vaccine technology. We announced that our license partner Pharmsynthez completed dosing in its Phase 2 clinical study with MyeloXen in patients with relapsing remitting and secondary progressive multiple sclerosis. MyeloXen was well tolerated by patients completing the study. We look forward to receiving further results of the trial with this promising drug candidate during 2015. Importantly, proof-of-concept data in humans generated by our partners in Russia and India reduce Xenetic's development costs as well as our development risk. Looking ahead We are excited about the many milestones we look to achieve during 2015. Among these are further results from the Phase 2 ErepoXen clinical trial being conducted in Australia and New Zealand. In addition, we plan to complete enabling studies for OncoHist in order to file an Investigational New Drug application with the FDA in AML, to initiate a Phase 2a study in 2015 in AML and possibly to initiate an additional Phase 2a study in another leukemia indication. We also plan to submit an orphan drug application in the U.S. and the EU for OncoHist in an additional hematology indication. One of our goals in 2014 was to list our common stock on the NASDAQ market. While we were not able to do so this past year, we remain committed to that goal as a priority for the Company; however, we cannot predict at this time when this may occur. Lastly, we invite you to view our updated corporate Fact Sheet, which contains further information on our milestones and growth strategy. You may access it by clicking here. We look forward to keeping you abreast of our progress and plans via periodic public conference calls, and plan to hold the next one in the first months of 2015. We will announce details of the call approximately one week prior. I would like to thank our employees, business partners and shareholders for their support throughout the year. We have great technologies, great IP, great programs, great partners and a robust management team that will leave no stone unturned to leverage our assets to deliver shareholder value. Sincerely,
