PLYMOUTH MEETING, Pa., Nov. 10, 2026 /PRNewswire/ -- INOVIO (NASDAQ: INO), a commercial-stage biotechnology company focused on developing DNA medicines to help treat and protect people from HPV-related diseases, cancer, and infectious diseases, today announced its financial results for the third quarter ended September 30, 2026 and provided an update on recent company developments. INOVIO's management will host a live conference call and webcast at 4:30 p.m. ET today to discuss third quarter 2026 results.

"We are delighted with the recent approval of VOCERYQ, which FDA described as a groundbreaking therapy that fights RRP at its source, not only its symptoms. INOVIO is now a commercial stage company with a primary goal to establish VOCERYQ as the preferred first-line immunotherapy for RRP patients," said Dr. Jacqueline Shea, INOVIO's President and Chief Executive Officer. "Our recently completed public offering provides additional financial resources to support a successful launch. Furthermore, this approval validates our DNA medicine platform and we are actively seeking partnerships to accelerate the development of other exciting candidates within our pipeline."

Operational Highlights

VOCERYQ – First FDA Approved DNA Medicine

The FDA granted accelerated approval for VOCERYQ (previously referred to as INO-3107) to reduce the frequency of surgery in adults with RRP on October 30, 2026. The indication was approved under the accelerated approval program based on demonstrated complete response defined as no requirement for surgical intervention in the 12 months after treatment in the efficacy population. VOCERYQ was approved in combination with CELLECTRA^® 5PSP, INOVIO's proprietary DNA medicine delivery device.

The approval was supported by data from INOVIO's RRP-001 study that evaluated VOCERYQ in 32 adult patients with RRP across multiple clinical sites. In the trial, VOCERYQ was found to be well tolerated. The complete clinical data for VOCERYQ were published in 2025 in Nature Communications and in The Laryngoscope. In October 2026, a further analysis of data was also published in The Laryngoscope under the title DNA Immunotherapy (INO-3107) Long-Term Efficacy Supported by Enhanced Immunogenicity in HPV-6/11 RRP.

To verify the clinical benefit of VOCERYQ, a confirmatory study is expected to be conducted.  INOVIO expects to submit a draft protocol for the study to FDA by the end of 2026 with the expectation of aligning on a final protocol by mid-2027. We also plan to submit an application for conditional marketing authorization for VOCERYQ in Europe before the end of 2026.

INOVIO expects to make VOCERYQ available to order and ship in approximately 60 days from the approval date and anticipates full field deployment during the first quarter of 2027. INOVIO's current inventory and capacity are expected to support at least the first year of launch through 2027. INOVIO has engaged Syneos Health to support the recruitment and deployment of its medical and commercial field teams. 

Next-Generation DNA Medicine Candidates

INOVIO presented nonclinical data highlighting the potential of its next-generation DNA-Encoded Protein (DPROT) programs at the Soft Bones Third International Meeting on Hypophosphatasia (HPP) in November 2026. With the recent approval of VOCERYQ validating the DNA Medicine platform, INOVIO is continuing discussions with potential partners to accelerate development of this promising platform with a focus on developing additional DPROT indications in rare diseases, including Hemophilia A, Fabry Disease and HPP.

Third Quarter 2026 Financial Results

• Research and Development (R&D) Expenses: R&D expenses for the three months ended September 30, 2026 decreased to $10.6 million from $13.3 million for the same period in 2025. The decrease was primarily the result of lower engineering outside services related to our device development and lower employee and consultant compensation, including stock-based compensation, among other variances.
  
  
• Selling, General and Administrative (SG&A) Expenses: SG&A expenses increased to $9.2 million for the three months ended September 30, 2026 from $7.9 million for the same period in 2025. The increase was due to the anticipated launch of VOCERYQ.
  
  
• Total Operating Expenses: Total operating expenses decreased to $19.8 million for the three months ended September 30, 2026 from $21.2 million for the same period in 2025.
  
  
• Net Loss: INOVIO's net loss for the three months ended September 30, 2026 was $49.2 million, or $0.50 per basic and diluted share, compared to a net loss of $45.5 million, or $0.87 per basic and diluted share, for the three months ended September 30, 2025. The increase in net loss was primarily driven by a $26.9 million non-cash loss on fair value adjustment related to our warrant liabilities for the three months ended September 30, 2026, compared to a $22.5 million non-cash loss for the same period in 2025. 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 loss.
  
  
• Cash, Cash Equivalents and Short-term Investments: As of September 30, 2026, cash, cash equivalents and short-term investments were $48.4 million (excluding net proceeds from the November 2026 offering of approximately $80.5 million), compared to $58.5 million as of December 31, 2025.

Cash Guidance

INOVIO estimates that current cash, cash equivalents and short-term investments will support operations into late fourth quarter 2027, past the launch of VOCERYQ. This projection includes the net proceeds of approximately $80.5 million from the public offering in November 2026 and $10.9 million in proceeds from the exercise of warrants subsequent to September 30, 2026, as well as an operational net cash burn estimate of approximately $21.0 million for the fourth quarter of 2026. These cash runway projections do not include the contribution of revenues from sales of VOCERYQ expected to commence in 2027 or any further capital-raising activities that INOVIO may undertake.

Conference Call / Webcast Information

INOVIO's management will host a live conference call and webcast at 4:30 p.m. ET today to discuss INOVIO's financial results and provide a general business update. The live webcast and replay may be accessed by visiting INOVIO's website at http://ir.inovio.com/events-and-presentations/default.aspx.

About RRP

RRP is a rare, debilitating disease caused primarily by HPV-6 and/or HPV-11. RRP is characterized by the development of small, wart-like growths, or papillomas, in the respiratory tract. While papillomas are generally benign, they can cause severe, life-threatening airway obstruction and respiratory complications. RRP can also significantly affect quality of life for patients by affecting the voice box, limiting the ability to speak effectively. Surgery to remove papillomas is the current standard of care for RRP; however, the papillomas often grow back. INOVIO's market research to date with patients and healthcare professionals indicates that a reduction of even one surgery matters, because every surgery poses a significant risk of causing permanent damage to the vocal cords and comes with potential costs to the patient, including adverse impacts to both quality of life and finances. Based on ongoing analysis of claims data, INOVIO believes there is a prevalent population of at least 25,000 patients with RRP in the United States, with additional patients diagnosed each year.  

About VOCERYQ™ 

VOCERYQ™ is a plasmid DNA-based immunotherapy designed to reduce the frequency of surgery for adults with RRP. VOCERYQ targets the root cause of RRP by generating an immune response using DNA plasmids that encode for HPV-6 and HPV-11 antigens. VOCERYQ is administered using the CELLECTRA^® delivery device. Following a standard-of-care surgical debulking of visible papilloma prior to the initial administration of VOCERYQ, no additional surgical intervention is required as part of the 9-week dosing regimen.  

The FDA previously granted VOCERYQ both Orphan Drug and Breakthrough Therapy designations, and the European Commission granted INO-3107 Orphan Drug designation.
