PLYMOUTH MEETING, Pa., March 18, 2025 /PRNewswire/ -- INOVIO (NASDAQ: INO), a biotechnology company focused on developing and commercializing DNA medicines to help treat and protect people from HPV-related diseases, cancer, and infectious diseases, today announced its financial results and operational highlights for the fourth quarter and full year ended December 31, 2024 and provided a business update and description of operational highlights during the year.

"INOVIO's recent progress puts us on the cusp of achieving several long-term goals for our DNA medicines, most importantly the submission of our first BLA and potential transition to a commercial-stage company," said Dr. Jacqueline Shea, INOVIO's President and Chief Executive Officer. "By resolving the previously announced device array component issue, we are back on track to submitting our first BLA for INO-3107 to the FDA. We anticipate starting our submission in mid-2025 with non-device related modules under the agency's rolling submission program, assuming it is granted, with the goal of having the complete submission accepted for priority review before the end of the year. We continue to believe that INO-3107 has the potential to be the preferred product candidate offering durable clinical benefit, tolerability and a patient-centric dosing regimen and are moving forward with urgency."  

Dr. Michael Sumner, INOVIO's Chief Medical Officer, said, "While delivering INO-3107 to patients remains our primary focus, we are extremely pleased with recently announced data from a proof-of-concept trial with our DMAb technology that showed durable in vivo antibody production. DMAbs represent a potential breakthrough as they have the ability to overcome traditional monoclonal antibody production challenges, such as short half-life and anti-drug immune responses. They have the potential to transform treatments for infectious diseases, as well as cancer and metabolic disorders by enabling long-term production of therapeutic antibodies and other proteins. Unlike other delivery platforms, our DNA-based approach has demonstrated sustained antibody production without generating anti-drug antibodies, making it a potentially promising long-term solution for conditions requiring continuous therapeutic protein delivery. We look forward to continuing to advance this technology and other promising pipeline candidates through collaborations and other potential strategic opportunities."

Operational Highlights

INO-3107 – Recurrent Respiratory Papillomatosis (RRP)

• Made significant progress toward submitting the BLA by completing the drafting of all non-device modules and resolving the previously announced manufacturing issue involving the single-use array component of the CELLECTRA device and enabling the final step of FDA-required device verification (DV) testing.
• Reported data from a retrospective trial (RRP-002) showing that patients continued to improve into years two and three following their initial dosing regimen when compared to their response at Week 52. In the trial, one-half of RRP patients treated with INO-3107 achieved a complete response (CR) and required no surgery in the second 12-month period when evaluated at the end of year two.
• Published and presented the full safety and efficacy data for the Phase 1/2 trial, as well as new immunology data demonstrating the ability of INO-3107 to induce antigen-specific T cell responses against HPV-6 and HPV-11 and drive recruitment of those T cells into airway tissues and papilloma of RRP patients, which could potentially slow or eliminate papilloma regrowth. This data was published in Nature Communications in February 2025.
• The European Medicines Agency's Committee for Advanced Therapies (CAT) certified the quality and non-clinical data for INO-3107, confirming that CMC data and nonclinical results available to date comply with the scientific and technical standards to be used in evaluating a potential European Marketing Authorization Application.
• INO-3107 was designated an innovative medicine as part of the U.K.'s Innovative Licensing and Access Pathway (ILAP).
• Progressed commercial readiness plans, including refining go-to-market strategy focused on patient and physician needs; driving key strategic decisions on pricing and access, product distribution, targeting and segmentation, and product positioning; and developing plans for the build out of the commercial organization.

Next Steps:

• Complete FDA-required design-verification testing - anticipated to be complete in first half of 2025.
• Update IND and initiate confirmatory trial.
• Submit BLA to the FDA – anticipate beginning rolling submission process mid-2025 and requesting priority review with goal of completing submission in second half of 2025 and receiving FDA acceptance of submission by year end.
• Submit a long-term study protocol to the FDA following BLA submission.
• Present and publish clinical, immunology and durability data at targeted scientific and medical conferences in 2025.

INO-3112 - Oropharyngeal Squamous Cell Carcinoma (OPSCC)

• Advanced development plans for a Phase 3 trial for INO-3112 in combination with LOQTORZI® (toripalimab-tpzi), a recently approved PD-1 inhibitor in the U.S. and Europe.
• Gained alignment with FDA on the planned Phase 3 trial design and received initial feedback from European regulatory authorities on proposed trial design.
• Entered into a clinical collaboration and supply agreement with Coherus BioSciences, Inc. for the use of LOQTORZI in the trial.

Next Steps:  

• Finalize protocol of the Phase 3 trial in consultation with the FDA. INOVIO anticipates it will conduct the trial in North America and Europe in patients with locoregionally advanced, high-risk, HPV16/18-positive OPSCC.
• Complete ongoing manufacture of drug supply for trial.

Other Pipeline Updates

• Top-line interim results were announced from an ongoing Phase 1 proof-of-concept trial evaluating DMAbs targeting COVID-19. In the trial, 100% (24/24) of participants who reached week 72 maintained biologically relevant levels of DMAbs, confirming the durability of in vivo antibody production. Notably, no participant developed anti-drug antibodies, a common challenge observed in other gene-based delivery platforms, such as adeno-associated virus mediated antibody expression. Additionally, the DMAbs were well tolerated in the trial, with the most common side effects being mild, temporary injection site reactions, such as pain and redness. The trial is being led by The Wistar Institute in collaboration with INOVIO, AstraZeneca, and the University of Pennsylvania and funded by the Defense Advanced Research Projects Agency (DARPA) and the Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND). INOVIO and its partners anticipate additional data to be presented at upcoming scientific conferences and published in a peer-reviewed journal.
  
  
• Advanced development plans for a Phase 2 trial for INO-4201 as a potential booster to ERVEBO® (rVSV-ZEBOV), including gaining alignment with FDA on the trial's protocol and path to potential approval. In 2025, the company anticipates finalizing the trial protocols and seeking funding to support trial activities. INOVIO also plans to submit the data from its completed Phase 1b trial to a peer-reviewed publication for publication, including FANG assay data indicating that boosting with INO-4201 can elicit neutralizing antibody response comparable to that achieved by ERVEBO, an approved primary series vaccination against Ebola.
  
  
• Continued efforts to move INO-5401 into its next stage of development for glioblastoma (GBM), which the company believes will be a controlled Phase 2 trial. INOVIO plans on completing manufacture of drug supply for the next trial during 2025.
  
  
• The Basser Center at the University of Pennsylvania continues evaluating the tolerability and immunogenicity of INO-5401 in a fully enrolled Phase 1 study exploring the potential to prevent cancer in people with BRCA1 or BRCA2 mutations.
  
  
• INOVIO's collaborator, ApolloBio, continues recruitment into its Phase 3 trial evaluating INO-3100 as a potential treatment for HPV 16/18 positive cervical dysplasia in China.
