INOVIO announced updates on the Phase 3 program for VGX-3100 for HPV-associated cervical high-grade squamous intraepithelial lesions (HSIL), including a one-year follow-up of efficacy and safety data in participants from REVEAL1, completing enrollment in REVEAL2, and advancing its pre-treatment biomarker candidate for VGX-3100 to be further developed with QIAGEN. In addition, INOVIO's development partner within Greater China (mainland China, Hong Kong, Macao, Taiwan), ApolloBio Corp. ("ApolloBio"), dosed the first participant in a separate Phase 3 trial in China. Key Updates for VGX-3100: REVEAL2 – INOVIO's second global Phase 3 clinical trial of VGX-3100 for cervical HSIL is fully enrolled and top-line efficacy and safety data are expected to be available in 2H22. REVEAL1 – the company completed the 52-week safety follow-up of participants in REVEAL1, company's first global Phase 3 trial of VGX-3100, and the safety profile of VGX-3100 observed at Week 36 remained well-tolerated through Week 88. In addition, participants treated with VGX-3100 who met the primary endpoint at Week 36 remained clear of HPV-16 and/or HPV-18 at Week 88. Pre-treatment Biomarker – INOVIO and QIAGEN have made progress in biomarker development by identifying candidate biomarker signatures for VGX-3100 with the intent of selecting a final signature in a pre-treatment in vitro diagnostic to improve the primary clinical outcome for biomarker-positive patients with cervical HSIL. Phase 3 Trial in China – The first participant has been dosed in the Phase 3 trial of VGX-3100 for cervical HSIL in China. This trial is being run by ApolloBio and is similar in design to REVEAL2. The trial is expected to enroll up to 84 participants.
