Xenetic Biosciences, Inc. Bolsters R&D and Regulatory Expertise with Appointment of Reid P. Bissonnette, Ph.D. as Executive Consultant for Translational Research and Development

Dr. Bissonnette brings over 25 years in small molecule and biotherapeutic drug discovery and development, oncology and inflammation research and regulatory expertise

FRAMINGHAM, MA / ACCESSWIRE / May 4, 2023 / Xenetic Biosciences, Inc. (NASDAQ:XBIO) ("Xenetic" or the "Company"), a biopharmaceutical company focused on advancing innovative immune-oncology technologies addressing hard to treat cancers, today announced it has engaged Reid P. Bissonnette, Ph.D. to serve as an executive consultant for translational research and development and to support the advancement of the Company's DNase-based oncology platform.

Xenetic's DNase-based oncology platform is designed to target neutrophil extracellular traps ("NETs"), which are weblike structures composed of extracellular chromatin coated with histones and other proteins. NETs are expelled by activated neutrophils, in response to microbial or pro-inflammatory challenges. However, excessive production or reduced clearance of NETs can lead to aggravated inflammatory and autoimmune pathologies, as well as creation and support of pro-tumorigenic niches in the case of cancer growth and metastasis, thereby potentially limiting response to therapy.

"Our confidence in the potential of our DNase-based oncology platform continues to grow and we are pleased with the advancements we have made to date. The depth and breadth of the expertise that Reid brings to our team will prove to be invaluable and is something we can leverage immediately as we look to further define our development and regulatory strategies towards our first FDA IND submission with our DNase-based technology platform," commented Jeffrey Eisenberg, Chief Executive Officer of Xenetic.

Dr. Bissonnette brings over 25 years of experience in small molecule drug discovery and development and biotherapeutics. He is a well-established translational scientist, drug hunter and senior manager of Oncology and Inflammation drug R&D, particularly with regards to targeted therapeutics, oncology, immuno-oncology, and inflammation therapeutics. He is well experienced in discovery, early and late-stage development, IND-enabling studies and translational sciences, biomarkers and pharmacodynamic markers, from concept to clinic and beyond, identifying and advancing potential therapies from small molecules to biologics including antibodies, ADCs, peptides and peptide drug conjugates and adoptive cell therapies.

Career appointments include serving as Consultant and Acting Head of Non-Clinical Research at Arrivent Biopharm; Vice President, Immuno-Oncology at TargaZyme Inc.; Vice President, Pharmacology at HUYA Biosciences International; Associate Director, Oncology Therapeutic Area Lead for the CovX Research Unit within Pfizer Worldwide R&D; and a number of roles at Ligand Pharmaceuticals, Inc. including Associate Director and Senior Research Investigator. He has established a successful track record in regulatory agency submissions (IND, NDA, Investigator's Brochure) and post-registration drug development as well as clinical trial design and protocol development and establishing and managing corporate and academic collaborations. He has authored over 60 publications and has built an intellectual property portfolio encompassing eight granted patents to date.

Dr. Bissonnette received his Bachelor of Science degree in Biochemistry and his Ph.D. in Tumor Immunology & Experimental Surgery from McGill University.
