Xenetic Biosciences, Inc. Reports Third Quarter 2022 Financial Results and Provides Business Update

- Continued advancement of lead technology, DNase-based oncology platform, in locally advanced or metastatic solid tumors towards Phase 1 clinical development
- Ended the quarter with $13.8 million of cash expected to fund operations and drive expanded pipeline development forward

FRAMINGHAM, MA / ACCESSWIRE / November 10, 2022 / Xenetic Biosciences, Inc. (NASDAQ:XBIO) ("Xenetic" or the "Company"), a biopharmaceutical company focused on advancing innovative immune-oncology technologies addressing hard to treat oncology indications, today reported its financial results for the third quarter of 2022 and provided a business update.

"We have continued to make encouraging progress with our recently in-licensed DNase-based oncology asset over the course of the past quarter and are excited about the potential of this platform technology," commented Jeffrey Eisenberg, Chief Executive Officer of Xenetic. "Looking ahead, our top priority remains on the advancement of our DNase oncology platform and moving it closer towards the clinic."

DNase Oncology Platform: Targeting Neutrophil Extracellular Traps ("NETs") to improve cancer therapies with a focus on advancing systemic DNase program into the clinic as an adjunctive therapy for pancreatic carcinoma and other locally advanced or metastatic solid tumors.

Program Highlights:

• Systemic DNase program initially targeting multi-billion-dollar indications including pancreatic carcinoma.
• Advancing toward planned first-in-human study to evaluate DNase combined with immune checkpoint inhibitors or chemotherapy.
• In August 2022, entered into a research and development collaboration agreement with VolitionRX Limited to develop NETs targeted, adoptive cell therapies potentially targeting multiple types of solid cancers.
• In June 2022, entered into a manufacturing agreement with Catalent Pharma Solutions LLC, which will include cGMP manufacturing of Phase 1 clinical supply.

PolyXen Platform Technology: Patent-protected platform technology designed for protein or peptide therapeutics, enabling next-generation biological drugs by prolonging a drug's circulating half-life and potentially improving other pharmacological properties.

Program Highlight:

• Royalty payments of approximately $0.4 million were received in the three months ended September 30, 2022, representing an approximate 18.6% increase over the same period in 2021 as Takeda's sublicensee continued its worldwide launch of the product.

Summary of Financial Results for Third Quarter 2022

Net loss for the quarter ended September 30, 2022 was approximately $0.8 million. Research and development expenses for the three months ended September 30, 2022 decreased by approximately $0.4 million, or 48.9%, to approximately $0.4 million from approximately $0.8 million in the comparable quarter in 2021 due to decreased spending related to our XCART™ platform technology program partially offset by spending related to our DNase oncology platform. General and administrative expenses for the three months ended September 30, 2022 decreased by approximately $82,000, or 8.7%, to approximately $863,000 from approximately $945,000 in the comparable quarter in 2021. The decrease was primarily due to a decrease in costs related to our intellectual property during the three months ended September 30, 2022, compared to the same period in 2021.

The Company ended the quarter with approximately $13.8 million of cash.
