Xenetic Biosciences reported a narrowing net loss driven by lower operating expenses while continuing to receive royalties from Takeda. Royalty revenue was $589,897 for the quarter and $1,183,158 for the six months ended June 30, 2025. The company recorded a net loss of $688,703 for the quarter and $1,591,844 for the six-month period. Cash totaled $4,779,846 at June 30, 2025 and working capital was approximately $4.5 million, while total assets were $5.35 million.
Operating costs fell year-over-year as R&D and general and administrative expenses declined, largely reflecting lower personnel and severance-related items recognized in 2024. Management states existing resources are adequate to fund operations for at least twelve months from issuance of these financial statements, but the company anticipates the need for additional capital longer term to advance its DNase clinical program and other initiatives.
