"With our first BLA now under review by the FDA, we are focused on delivering INO-3107 to RRP patients who are desperate for treatment options that reduce reliance on surgery to control this rare and devastating disease," said Dr. Jacqueline Shea, INOVIO’s President and Chief Executive Officer. "Our top priority is advancing INO-3107, and to do so, optimizing and extending our financial resources towards our target PDUFA date of October 30, 2026. We are excited about the opportunities ahead as we prepare to become a commercial-stage company and work to leverage the power of partnerships to advance other promising candidates in our pipeline. I look forward to providing more updates on our progress with these efforts in the coming months."

Operational Highlights

INO-3107 – Recurrent Respiratory Papillomatosis (RRP)
In December 2025, the FDA accepted INOVIO’s BLA for INO-3107 for review under the accelerated approval program as a potential treatment for adults with RRP. As part of the submission, INOVIO requested a priority review, which is typically 6 months. Instead, the FDA granted a standard 10-month review with a PDUFA target date set for October 30, 2026.

While the BLA was accepted under the accelerated approval program, in the file acceptance letter the FDA noted as a potential review issue its preliminary conclusion that the company had not provided adequate information to justify eligibility for the accelerated approval pathway. INOVIO continues to strongly believe that INO-3107 fulfills the criteria for accelerated approval, meeting a significant unmet need and providing a meaningful therapeutic benefit over existing treatments. The FDA has agreed to a yet-to-be-scheduled meeting to discuss eligibility for review under the accelerated approval program.

During 2025, INOVIO published clinical and immunological results from its Phase 1/2 trial (RRP-001) in Nature Communications showing that INO-3107 induced new populations of T cells in the blood that traveled to airway tissue and were associated with significant clinical benefit as measured by reduced need for surgery. INOVIO also published data from a retrospective study (RRP-002) investigating the long-term safety and clinical response of patients treated with INO-3107 in The Laryngoscope. Data demonstrated that the majority of patients experienced continued improvement beyond the initial 12-month study period of the previously published Phase 1/2 trial (RRP-001), as measured by a reduction in the number of surgical procedures needed after treatment with INO-3107.

INOVIO also continued to advance commercial readiness plans, including conducting critical market research supporting a positively differentiated product profile, developing a pricing strategy, finalizing our go-to-market model, and advancing the build-out of our commercial organization. We’ve also selected key commercial partners including a third-party logistics provider, Agency of Record, specialty distributor, specialty pharmacy, and patient HUB.

INO-5412/INO-5401
INOVIO announced a clinical trial collaboration and supply agreement with Akeso Inc. to evaluate INO-5412 (INO-5401 plus INO-9012 in a single vial) in combination with cadonilimab, Akeso’s first-in-class PD-1/CTLA-4 bispecific antibody, for the potential treatment of GBM. The combination therapy will be studied as a part of the INdividualized Screening trial of Innovative Glioblastoma Therapy (INSIGhT), the innovative Phase 2 adaptive platform trial sponsored by the Dana-Farber Cancer Institute and conducted by Mass General Brigham Cancer Care Inc. that is designed to quickly and efficiently find new treatments for GBM. The novel combination of INO-5412 with cadonilimab builds on INOVIO’s previous promising research in GBM and could potentially benefit patients by providing additional checkpoint inhibition through CTLA-4 binding.

INOVIO also continues to dose patients in the GBM-001 Phase 1/2 trial in newly diagnosed glioblastoma that combines INO-5401 plus INO-9012 with Regeneron’s PD-1 checkpoint inhibitor Libtayo.

INOVIO’s partners at the Basser Center at the University of Pennsylvania continue to evaluate the tolerability and immunogenicity of INO-5401 plus INO-9012 in a Phase 1 study exploring the potential to prevent cancer in people with BRCA1 or BRCA2 mutations.

Next Generation DNA Medicine Candidates
Results from a Phase 1 proof-of-concept trial evaluating next generation DMAbs for COVID-19 were published online in Nature Medicine, demonstrating the technology’s potential as a long-acting, scalable and tolerable alternative to traditional monoclonal antibody therapies. The study is being led by The Wistar Institute in collaboration with INOVIO, AstraZeneca, and clinical investigators at the Perelman School of Medicine at the University of Pennsylvania. This was the first demonstration that DNA plasmid encoded monoclonal antibodies, which are complex proteins, can be durably and tolerably expressed in humans.

INOVIO also presented promising Factor VIII preclinical data from its DPROT program at the World Federation of Hemophilia Global Forum in November 2025. This technology aims to address some of the shortcomings of conventional therapeutic protein replacement treatments, including gene therapy approaches. INOVIO is developing additional DPROT indications and is actively seeking partners to accelerate development of this promising program.

General Corporate
INOVIO remains focused on financial discipline, directing resources to advance the INO-3107 program towards commercialization and a potential approval date in October 2026, and extending the cash runway. To achieve this goal, INOVIO has further prioritized programs, spending, and resource needs, and has eliminated roles that don’t directly support our primary goal of advancing INO-3107 toward US approval.

2025 Financial Results

Research and Development (R&D) Expenses: R&D expenses for the quarter and year ended December 31, 2025 were $10.3 million and $54.2 million, respectively, compared to $12.9 million and $75.6 million for the same periods in 2024. The decrease was due primarily to the result of lower drug manufacturing, clinical study and other expenses related to INO-3107, lower contract labor and lower expensed inventory, among other variances.

General and Administrative (G&A) Expenses: G&A expenses were $7.2 million and $32.7 million, respectively, for the quarter and year ended December 31, 2025, versus $7.6 million and $37.0 million, respectively, for the same periods in 2024. The decrease in G&A expenses was primarily related to a decrease in employee and consultant compensation, including stock-based compensation, among other variances.

Total Operating Expenses: Total operating expenses were $17.5 million and $86.9 million for the quarter and year ended December 31, 2025, respectively, compared to $20.5 million and $112.6 million for the same periods in 2024.

Net Loss: INOVIO’s net income (loss) for the quarter and year ended December 31, 2025 was $3.8 million, or $0.06 per basic and ($0.26) per diluted share, and ($84.9) million, or ($1.81) per basic and diluted share, respectively, compared to net loss of $19.4 million, or $0.65 per basic and diluted share, and $107.3 million, or $3.95 per basic and diluted share, for the quarter and year ended December 31, 2024, respectively. The net income for the fourth quarter 2025 was primarily driven by a $21.2 million non-cash gain on fair value adjustment related to our warrant liabilities. As the fair value of the warrants fluctuates with our share price and other market inputs, this adjustment can result in significant variability in our reported net income (loss).

Shares Outstanding: As of December 31, 2025, INOVIO had 69.0 million common shares outstanding and 109.7 million common shares outstanding on a fully diluted basis, after giving effect to the exercise, vesting, and conversion, as applicable, of its outstanding common stock warrants, stock options, restricted stock units and convertible preferred stock.

Cash, Cash Equivalents and Short-term Investments: As of December 31, 2025, cash, cash equivalents and short-term investments were $58.5 million compared to $94.1 million as of December 31, 2024.
