Insights
INOVIO's INO-3107 shows increasingly positive long-term results for RRP, with surgery needs dropping 78% by year 2, suggesting strong commercial potential.
The peer-reviewed data published in The Laryngoscope provides compelling evidence of INO-3107's durable efficacy in treating Recurrent Respiratory Papillomatosis (RRP). The retrospective analysis reveals progressive improvement over time - a rare and valuable characteristic for any therapeutic. The overall response rate improved from 72% in Year 1 to 86% in Year 2, while complete responses (patients requiring zero surgeries) increased from 28% to 50%.
What's particularly significant is the continued reduction in surgical burden - from a baseline of 4.1 surgeries annually before treatment to just 0.9 surgeries by Year 2, representing a 78% reduction in surgical interventions. This trajectory appears to continue improving into Year 3 based on partial data.
For RRP patients, each surgery avoided represents meaningful clinical benefit. RRP is a debilitating condition where HPV causes recurrent growths in the respiratory tract, requiring repeated surgical removal to maintain airway patency. These frequent surgeries can lead to voice damage, psychological distress, and significant healthcare costs.
The safety profile appears favorable with no reported serious adverse events or long-term safety concerns, which is critical for a therapy targeting a chronic condition requiring long-term management.
This DNA immunotherapy represents a potential paradigm shift in RRP management, moving from purely symptomatic surgical intervention to addressing the underlying HPV infection driving the disease. The sustained and improving efficacy demonstrated here substantially strengthens INO-3107's clinical profile and commercial potential as it advances toward potential regulatory approval.
- Retrospective trial showed Overall Response Rate (ORR) improved to
86% at the end of the second 12-month period (Year 2) compared to72% observed at the end of the initial 12-month Phase 1/2 trial (Year 1); the Complete Response (CR) rate improved to50% for Year 2 from28% for Year 1 - Mean number of surgeries patients needed to control their RRP continued to drop from 4.1 surgeries per year prior to receiving INO-3107 to 1.7 for Year 1 to 0.9 for Year 2
- Partial data into the third 12-month period (Year 3 - median follow up 2.8 years following initial treatment) continued the trend of improvement and a reduced number of surgeries
"The most important takeaway from this data is that the majority of patients experienced a reduction in surgeries following initial treatment with INO-3107, and almost all of those patients maintained or improved their response 2 years after initial treatment," said Dr. Aaron Friedman, Associate Professor of Clinical Otolaryngology, Head and Neck Surgery, University of Cincinnati Medical Center, and a principal investigator on the trial. "With this continued improvement in clinical effect, we believe INO-3107 has the potential to change the trajectory of a patient's disease and set a new standard of care for the RRP community."
"Understanding how much every single surgery matters to patients, it is compelling to see the vast majority of patients experienced significant benefit from treatment with INO-3107, resulting in a reduction in the number of surgeries required to control their disease — a benefit that continued and often improved over time," said Dr. Jacqueline Shea, INOVIO's President and Chief Executive Officer. "The sustained reduction in surgery following treatment with INO-3107 demonstrated here is central to our belief that INO-3107 could become the preferred product on the market, if approved"
A Phase 1/2 open-label trial of INO-3107 (RRP-001) in 32 patients, previously published in Nature Communications, demonstrated a statistically significant reduction in the number of surgeries needed to control their RRP when comparing the 12 months following the initiation of treatment with INO-3107 versus the 12 months prior to beginning treatment with INO-3107. The retrospective trial published today in The Laryngoscope (RRP-02) collected data on 28 of the original 32 patients in RRP-001 to assess the longer-term treatment effect of INO-3107. The median follow-up period for both RRP-001 and RRP-002 combined was 2.8 years from treatment initiation. The efficacy assessment was defined by the number of RRP surgical interventions reported. The safety evaluation included reported serious adverse events (SAEs).

About RRP
RRP is a debilitating and rare 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 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. The most widely cited
About INO-3107
INO-3107 is an investigational DNA medicine designed to elicit an antigen-specific T cell response against both HPV-6 and HPV-11 proteins. These targeted T cells seek out and kill HPV-6 and HPV-11 infected cells, with the aim of potentially preventing or slowing the growth of new papillomas. In a Phase 1/2 trial of 32 participants (RRP-001),
The FDA has granted INO-3107 both Orphan Drug and Breakthrough Therapy designations and has advised INOVIO that it can submit a biologics license application under the FDA's accelerated approval program using data from INOVIO's completed Phase 1/2 trial. The European Commission granted INO-3107 Orphan Drug designation. In addition, INOVIO has CE-marked its CELLECTRA® delivery device in the EU, which allows INOVIO to commercialize the device in the EU and other geographies that recognize CE-marking. The
