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 reported financial results for the quarter and year ended December 31, 2022, and provided a business update. INOVIO's management will host a live conference call and webcast with slides at 4:30 p.m. Eastern Time today to discuss financial results and provide a general business update for the fourth quarter. The live webcast and replay may be accessed by visiting INOVIO's website at http://ir.inovio.com/events-and-presentations/default.aspx.
INOVIO's President and Chief Executive Officer, Dr. Jacqueline Shea, said, "The last year has been one of transition for INOVIO. We chose to make some difficult but essential decisions to best position our pipeline and organization for the future, and we are a stronger company because of it. We've honed our strategic vision, strengthened our financial position, and maintained our cash runway into first quarter 2025, enabling us to focus energy and resources on advancing candidates with scientific promise, achievable pathways to market, and strong commercial potential. Our continued commitment to financial discipline and operational excellence will guide us as we work to get those candidates across the finish line and ultimately deliver on the promise of DNA medicines for patients."
Dr. Shea continued, "Discussions are underway regarding next steps for our candidates with the greatest potential for impact, including INO-3107 as a potentially life-changing treatment for Recurrent Respiratory Papillomatosis (RRP) and INO-4201 as an Ebola vaccine booster. Today we also shared data from REVEAL2, the second trial in our program evaluating VGX-3100 as a treatment for cervical high-grade squamous intraepithelial lesions (HSIL). While the investigational biomarker-selected population did not achieve statistical significance, trial results did achieve statistical significance in the all-participants population. The overall evidence of viral clearance observed is encouraging as it builds upon the growing body of work pointing to the potential of our DNA Medicines platform in HPV diseases. We will certainly take that into consideration as we assess next steps for VGX-3100 and our broader portfolio. I believe that our increased experience with HPV therapeutics, coupled with our strengthened strategic focus over the past year, positions INOVIO to make meaningful advancements in our mission to bring innovative, life-saving DNA medicines to market."
REVEAL2 Data Results for VGX-3100 in Cervical HSIL
INOVIO today announced results for REVEAL2. The company previously announced this trial was no longer pivotal and would not lead to a biologics license application (BLA) for a biomarker-selected population, as the U.S. Food and Drug Administration (FDA) had indicated that one or more additional trials would be required.
REVEAL2 was the second Phase 3 trial evaluating VGX-3100 for efficacy, safety, tolerability, and immunogenicity in treating HPV-16/18-related cervical HSIL. Trial participants included 203 women, 18 years of age or older, with histologically-confirmed cervical HSIL associated with HPV-16 and/or HPV-18, but who were otherwise healthy (NCT03185013). Participants received either VGX-3100 or placebo at weeks 0, 4 and 12 (randomized 2:1). In April 2022, the trial was amended to utilize a biomarker-selected population as the primary population, based on prior analysis that this investigational biomarker had the potential to identify women more likely to respond to treatment with VGX-3100.
In this trial, statistical significance was not achieved in the investigational biomarker-selected population for the endpoint of lesion regression and viral clearance. However, statistical significance was achieved in the all-participants population for the endpoint of lesion regression and viral clearance.
The percentage of participants in the investigational biomarker-selected population meeting the primary endpoint was 28.6% (6/21) in the treatment group, versus 0% (0/4) in the placebo group (p=0.115; difference in percentage 28.6, 95%CI: -24.6, 50.4), which was not statistically significant.
The result for the secondary endpoint of regression of HSIL and clearance of virus in the all-participants population of 203 participants (134 participants in the treatment group, 69 in the placebo group) was statistically significant, with 27.6% (37/134) of the participants meeting the endpoint in the treatment group, versus 8.7% (6/69) in the placebo group (p=0.001; difference in percentage 18.9, 95%CI: 7.8, 28.6).
In particular, in the all-participants population of REVEAL2, viral clearance was observed in 37.3% (50/134) in the 3-dose treatment group versus 8.7% (6/69) in the placebo group. Given the importance of viral clearance in removing the underlying cause of the HPV-related diseases, this data may have positive implications for our other HPV-related programs.
An ad-hoc integrated efficacy analysis of the results for both REVEAL1 and REVEAL2 shows statistical significance in both the biomarker-selected and all-participants populations. For the combined biomarker-selected population of 92 participants (68 participants in the treatment group, 24 in the placebo group), the percentage of participants meeting the endpoint was 54.4% (37/68 in the treatment group, versus 12.5% (3/24) in the placebo group (p 2022 Global Data Point.
