PLYMOUTH MEETING, Pa., Aug. 9, 2023 /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 for the second quarter ended June 30, 2023 and provided a strategic update.

"We continue to make progress with INO-3107, our candidate for the treatment of recurrent respiratory papillomatosis (RRP). Following positive results from our Phase 1/2 trial earlier this year, we are pleased to announce that we are targeting to have the first patient dosed in a Phase 3 trial in adults in the first quarter of 2024, moving us one step closer to delivering on the promise of DNA medicines for patients suffering from this debilitating disease," said Dr. Jacqueline Shea, INOVIO's President and Chief Executive Officer. "Based on our interactions with the U.S. Food and Drug Administration (FDA) we believe that we have an acceptable trial design. We are addressing what we believe to be their final questions before we commence our pivotal Phase 3 trial for patients with RRP."

"As we move forward with our pipeline, we are focused on making sure our company is scaled for success in light of the challenging funding environment, particularly for pre-commercial biotech companies like INOVIO," Dr. Shea continued. "With that in mind, we made the difficult decision to further reduce our headcount and operational spending to better align with our strategic priorities. We believe that with the pipeline reprioritization announced today, we are well-positioned to execute on our development plans for INO-3107 while also advancing other promising candidates, such as INO-3112, INO-5401, VGX-3100 for anal HSIL and INO-4201. We expect that our existing cash resources will allow us to achieve important catalysts for these programs. I would like to extend my deepest gratitude to all of our employees – past and present – for their efforts on behalf of the company and contributions to the important progress we're making."

Pipeline Reprioritization and Corporate Reorganization

INO-3107 – Recurrent Respiratory Papillomatosis (RRP)

• INOVIO has announced today that it is further reprioritizing its pipeline to focus on its highest potential, closest to market programs, specifically its late-stage clinical program for INO-3107 as a treatment for RRP. In a Phase 1/2 trial involving RRP patients, treatment with INO-3107 resulted in a statistically significant reduction in the number of surgical interventions required to manage the disease. INOVIO is targeting to commence its pivotal Phase 3 trial in adult patients with RRP, subject to clearance by regulators, in the first quarter of 2024.
  
  
• On May 5, 2023, data from the Phase 1/2 trial of INO-3107 were presented by lead investigator Dr. Ted Mau at the scientific program of the American Broncho-Esophagological Association (ABEA) at the Combined Otolaryngology Spring Meetings (COSM) in Boston, Massachusetts. The presentation highlighted the safety profile of INO-3107, which was well tolerated by participants in the trial and resulted in mostly low-grade (Grade 1) treatment-emergent adverse effects (TEAEs) such as injection site pain and fatigue. There were no high-grade TEAEs deemed related to treatment and no TEAEs leading to treatment discontinuation. Treatment with INO-3107 induced cellular immune responses against both HPV-6 and HPV-11, with activated CD4 and CD8 T cells, including cytotoxic CD8 T cells thought to be important for clearance of virally infected cells. Preliminary analysis indicates a potential correlation between T-cell responses and reduction of surgeries. T-cell responses were also observed at Week 52, indicating a persistent cellular memory response.
  
  
• Also in May 2023, INO-3107 was granted orphan drug designation by the European Commission (EU) as a potential treatment for RRP. INO-3107 was granted orphan drug designation from the FDA in July 2020, making it the first RRP product candidate to receive designations from both U.S. and EU regulatory bodies.

VGX-3100 – Cervical High-Grade Squamous Intraepithelial Lesions (HSIL)

• INOVIO has decided to cease all further development of VGX-3100 as a potential treatment for cervical HSIL in the United States. This decision is driven by a number of factors, including the recent analysis of biomarker data from REVEAL2 indicating that substantial work would be needed to refine this novel biomarker before it could be used in any further Phase 3 trials. Previously, the U.S. FDA indicated that at least one or more additional well-controlled trials would need to be conducted in the biomarker-positive population before being considered for registration. Given these factors, INOVIO has determined that its resources are best invested in other pipeline candidates with a faster potential path to market. INOVIO remains encouraged by the data collected in both of its completed Phase 3 trials for VGX-3100 in cervical HSIL (REVEAL1 and REVEAL2). In these trials, the data showed that VGX-3100 could clear both virus and lesions, which INOVIO believes could be supportive evidence for pursuing regulatory approval in other global markets.
  
  
• For non-U.S. markets, where the access to and options for treatment differs, INOVIO believes that VGX-3100 could be a valuable treatment option for cervical HSIL should current and future trials continue to show potential efficacy and achieve regulatory approvals. For the Chinese market, INOVIO's partner ApolloBio continues to advance the development of VGX-3100 for cervical HSIL in a Phase 3 trial. This trial is designed to use a similar protocol to that of REVEAL1 and does not utilize the novel biomarker used in INOVIO's REVEAL2 trial. INOVIO also continues to discuss the clinical development of VGX-3100 with potential partners in other global markets.

Other VGX-3100 Indications and Clinical Pipeline Candidates

• Pending discussions with regulators, INOVIO plans to investigate opportunities to advance VGX-3100 as a potential treatment for anal HSIL, an indication that continues to have significant unmet need. Results published in the New England Journal of Medicine in June 2022 from a multi-year study sponsored by the National Cancer Institute, called the ANCHOR study, showed "for the first time that treating anal HSIL is effective at reducing the incidence of anal cancer in a very high-risk group of people – people living with HIV" (NCI press release, June 15, 2022). INOVIO has observed that this study produced results that are moving the medical community away from the historical practice of actively monitoring anal HSIL and toward a more proactive approach in treating lesions that can progress to cancer. The challenge for patients and their healthcare providers in taking a more proactive approach is that there are few effective options available to treat anal HSIL. VGX-3100 has the ability to clear HPV-16/18 lesions and virus, which was not only observed in the cervical HSIL Phase 3 trials, but also in an open-label Phase 2 anal HSIL trial in HIV negative people. VGX-3100 is currently being investigated in an ongoing Phase 2 trial in HIV-positive anal HSIL patients being conducted by the AIDS Malignancy Consortium.
  
  
• INOVIO is also working to advance its oncology product candidates, specifically INO-5401 and INO-3112, which target glioblastoma (GBM) and HPV-related cancers, respectively, as well as other candidates in its early-stage clinical pipeline targeting infectious diseases, in particular the company's Ebola vaccine candidate, INO-4201. Progress for these candidates has continued in the areas of manufacturing, regulatory submissions, and partnership discussions. The next stage of clinical development will most likely require additional funding or partnerships.

Corporate Restructuring

• As a result of the decision to focus its resources on its late-stage candidates with the greatest likelihood of success, including stopping the development of VGX-3100 in cervical HSIL for the U.S. market, INOVIO has taken steps to further conserve its capital resources. The company recently announced plans to further reduce its workforce by 58 employees, or 30%. The company estimates the cost savings from the headcount reduction will provide annual savings of approximately $9.9 million, which alongside other reductions in spending would allow the company to extend its cash runway into the third quarter of 2025.

Second Quarter 2023 Financial Results

• Cash, Cash Equivalents and Short-term Investments: As of June 30, 2023, cash, cash equivalents and short-term investments were $194.9 million compared to $253.0 million as of December 31, 2022.
