Encouraging preclinical data supporting the use of DNase-based technology to target NETosis and address difficult to treat cancers

Strategic focus on exploratory investigator-initiated clinical studies with institutional partners

Continued progress of DNase I development program towards IND and first-in-human study for treatment of pancreatic carcinoma

FRAMINGHAM, MA / ACCESS Newswire / March 19, 2025 / Xenetic Biosciences, Inc. (NASDAQ: XBIO) ("Xenetic" or the "Company"), a biopharmaceutical company focused on advancing innovative immuno-oncology technologies addressing difficult to treat cancers, today reported its financial results for the year ended December 31, 2024.

Recent Highlights

• Extended its collaborations with the University of Virginia and Scripps Research through 2025;

• Entered into a Clinical Trial Services Agreement with PeriNess Ltd. to manage investigator initiated exploratory studies of DNase I in combination with chemotherapy and immunotherapy platforms for the treatment of pancreatic carcinoma, colorectal cancer and other locally advanced or metastatic solid tumors; and

• Continued pursuit of other strategic collaborations to advance the Company's technology.

"Over the course of 2024, our team made notable advancements across multiple fronts. We continued to establish and present a growing body of preclinical data that supports the use of our DNase-based technology across several cancer indications. Additionally, we continued to engage institutional partners to drive our development strategies forward including investigator-initiated studies and partnering on various other efforts. Leveraging these relationships allows us to advance our technology toward the clinic while utilizing our resources efficiently and minimizing our internal investment. Looking ahead to 2025, we are executing on our initiatives as we progress toward an IND and Phase 1 clinical trial and look forward to an exciting year," commented James Parslow, Interim Chief Executive Officer and Chief Financial Officer of Xenetic.

Xenetic continues to advance its DNase-based technology towards Phase 1 clinical development for the treatment of pancreatic carcinoma and other locally advanced or metastatic solid tumors. Preliminary preclinical studies evaluating the combinations of DNase I with chemotherapy and DNase I with immuno-therapies in colorectal cancer models as well as CAR-T therapy have been completed.

Summary of Financial Results for Fiscal Year 2024

Net loss for the year ended December 31, 2024 was approximately $4.0 million. Research and development expenses for the year ended December 31, 2024 decreased by approximately $0.2 million, or 5.9%, to $3.3 million from $3.5 million in the prior year period. This decrease was primarily due to decreased spending in connection with the Company's DNase process development efforts. Royalty payments received from the Company's sublicense with Takeda Pharmaceuticals Co. Ltd in the year ended December 31, 2024 were approximately $2.5 million, relatively flat with that of the year ended December 31, 2023. General and administrative expenses for the year ended December 31, 2024 were $3.4 million, decreasing by approximately $0.1 million, or 4.1%, compared to the prior year. The decrease was primarily due to a reduction in legal and accounting costs during the year ended December 31, 2024 compared to the prior year. These decreases were substantially offset by certain severance and benefits expensed in connection with a separation agreement entered into during the second quarter of 2024.

The Company ended the year with approximately $6.2 million of cash.
