GERMANTOWN, Md., Aug. 07, 2025 (GLOBE NEWSWIRE) -- Barinthus Biotherapeutics plc (NASDAQ:BRNS) ("Barinthus Bio," or the "Company"), an immunology and inflammation ("I&I") company focused on developing therapies that promote immune tolerance with curative potential, today announced its financial results for the quarter ended June 30, 2025, and provided an overview of the Company's corporate developments.

"In the second quarter, we remained laser-focused on advancing VTP-1000, our highly differentiated immunotherapy designed to prevent or reduce symptoms following gluten exposure in patients with celiac disease," said Bill Enright, Chief Executive Officer of Barinthus Bio. "We are currently screening patients for the last cohort of the SAD portion of the Phase 1 AVALON trial, and as planned, we initiated the MAD portion of the trial, which includes a gluten challenge, enabling us to assess the potential efficacy of VTP-1000 at this early stage. We look forward to reporting topline data from the SAD portion of the trial early in the fourth quarter of 2025."

Second Quarter 2025 Financial Highlights

• Cash: As of June 30, 2025, cash, cash equivalents and restricted cash was $87.8 million, compared to $100.6 million as of March 31, 2025. The $12.8 million decrease is a result of the net cash used in operating activities of $18.1 million for the development of our pipeline and general corporate expenses, offset by a $5.3 million translational gain from the conversion of balances in pound sterling denominated entities to the United States dollar reporting currency. Based on current research and development plans, the Company expects its available resources to fund its operating expenses and capital expenditure requirements into 2027.
• Research and Development Expenses: Research and development expenses were $8.0 million in the second quarter of 2025 compared to $8.3 million for the first quarter of 2025, with the decrease attributable to a reduction in preclinical activity and a reduction in workforce. The quarter-on-quarter research and development expenses per program are outlined in the following table, with the expense primarily attributable to completion and presentation of preliminary results data from the two phase 2 clinical trials of VTP-300 that were presented at the European Association for the Study of the Liver ("EASL") Congress 2025 in May, and the continued progression of the phase 1 AVALON clinical trial of VTP-1000 in celiac disease. It is anticipated that research and development expenses related to the legacy programs in infectious disease and oncology will reduce going forward as the ongoing clinical trials complete, and that research and development expenses related to autoimmune programs will continue or increase, as the clinical development continues.

¹ This includes expenses relating to the infectious disease and oncology programs; VTP-850 Prostate cancer, VTP-200 HPV, VTP-600 NSCLC (the Phase 1/2a trial is sponsored by Cancer Research UK) and VTP-500 MERS (funded pursuant to an agreement with the Coalition for Epidemic Preparedness Innovations ("CEPI"). Expenses relating to these programs were previously presented separately, but are now aggregated for the prior period comparative.

² This includes $0.1 million and $0.2 million for the six months ended June 30, 2025 and 2024, respectively, of personnel-related indirect expenses relating to time spent progressing the VTP-500 MERS program, which is funded by CEPI.

• General and Administrative Expenses: General and administrative expenses were $15.4 million for the second quarter of 2025, compared to $12.6 million for first quarter of 2025. The increase of $2.8 million relates primarily to an increase in unrealized losses on foreign exchange driven mainly by translation of United States dollar balances in pound sterling denominated entities.
• Net Loss: For the second quarter of 2025, the Company generated a net loss attributable to its shareholders of $21.1 million, or $(0.52) per share on both basic and fully diluted bases, compared to a net loss attributable to its shareholders of $19.7 million, or $(0.49) per share on both basic and fully diluted bases for the first quarter of 2025.
