[{"type":"text","content":"Trial achieved primary and secondary efficacy endpoints among all evaluable subjects in the Phase 3 multi-center, randomized, double-blind, placebo-controlled trial\n VGX-3100 is the first DNA medicine to achieve efficacy endpoints in a Phase 3 clinical trial\n INOVIO also continues to partner with QIAGEN to develop a pre-treatment predictive biomarker with the goal of identifying women expected to respond to VGX-3100\n\n\nPLYMOUTH MEETING, Pa., March 1, 2021 /PRNewswire/ -- INOVIO, (NASDAQ:INO), a biotechnology company focused on bringing to market precisely designed DNA medicines to treat and protect people from infectious diseases, cancer and HPV-associated diseases, today announced it met primary and secondary endpoints among all evaluable subjects for the REVEAL 1 trial. This trial is one of two ongoing pivotal, randomized, double-blind, multi-center, placebo-controlled, Phase 3 trials (REVEAL 1 and REVEAL 2) evaluating the safety, tolerability and efficacy of VGX-3100 to treat HPV-16/18-associated cervical high-grade squamous intraepithelial lesions (HSIL) using the company's proprietary CELLECTRA® 5PSP device. \nThe trial protocol-defined modified intention to treat (mITT) population (N=193) includes all subjects with endpoint data. For the primary endpoint of histopathological regression of HSIL combined with virologic clearance of HPV-16 and/or HPV-18 at week 36, the percentage of responders was 23.7% (31/131) in the treatment group, versus 11.3% (7/62) in the placebo group (p=0.022; 12.4% difference in percentage, 95%CI: 0.4,22.5), thus achieving statistical significance. All secondary efficacy endpoints were achieved. These endpoints were: a) regression of cervical HSIL to normal tissue combined with HPV-16/18 viral clearance, b) regression of cervical HSIL alone, c) regression of cervical HSIL to normal tissue, and d) HPV-16/18 viral clearance alone. \nThe trial protocol-defined intention to treat (ITT) population (N=201) includes all randomized subjects regardless of availability of endpoint data and defines those without endpoint data as non-responders. There were eight such subjects (seven in the treatment group, one in the placebo group). Including subjects with missing endpoint data, the percentage of subjects meeting the primary endpoint was 22.5% (31/138) in the treatment group, versus 11.1% (7/63) in the plac...
