Company to report preliminary efficacy data later this year
PLYMOUTH MEETING, PA, USA I August 19, 2019 I Inovio Pharmaceuticals, Inc. (NASDAQ: INO) announced today that it has completed enrollment in the company’s open-label, 24 patient, Phase 2 trial with its lead immunotherapy product VGX-3100 in patients with precancerous lesions of the anus, i.e. anal high-grade squamous intraepithelial lesions (anal HSIL, aka anal intraepithelial neoplasia). VGX-3100 is an immunotherapy that targets human papillomavirus (HPV) 16 and 18 and is being studied for the treatment of HPV-related precancerous lesions and the HPV infection that causes these lesions. Inovio is already evaluating VGX-3100 in two Phase 3 registration trials to treat cervical dysplasia caused by HPV, for which the company has previously announced the completion of enrollment for the first of those pivotal trials, REVEAL 1.
This open-label, multi-center Phase 2 study is designed to evaluate the safety and efficacy of VGX-3100 administered Inovio’s CELLECTRA® delivery system in adult men and women with anal HSIL caused by HPV-16 and/or HPV-18 and builds on significant clinical benefits demonstrated with Inovio’s HPV immunotherapies in multiple clinical trials. VGX-3100 in a Phase 2 proof-of-concept trial for cervical dysplasia demonstrated a complete response in 43 out of 107 patients in regression of high grade cervical lesions and elimination of the underlying HPV infection. Additional 2 out of 4 metastatic head and neck cancer patients treated with MEDI0457 and a PD-1 check point inhibitors in a Phase 1 study experienced a long-term complete response for more two years and counting. The other 18 out 22 head and neck patients treated with MEDI0457 have not progressed for over 4 years post-treatment. Lastly, a pilot study of Inovio’s immunotherapy in recurrent respiratory papillomatosis (RRP) resulted in 2 out of 2 patients delaying surgery due to lack of tumor recurrence.
Dr. J. Joseph Kim, Inovio’s President and CEO, said, “We are very excited to expand the target indication for VGX-3100 to treat rare and difficult to treat diseases like anal HSIL, which have a high recurrence rate that requires multiple, repeat surgeries. A new immunotherapy that could effectively eliminate or delay surgery could be transformative for patients with this high unmet medical condition, Inovio plans to report preliminary efficacy and safety data from this Phase 2 study in the fourth quarter.”
Anal HSIL or dysplasia is an orphan disease and the precursor to anal cancer, which is estimated to cause more than 1,280 deaths in the United States in 2019. Anal HSIL is estimated to occur in nearly 20,000 new cases annually. However, that is very likely an underestimate given that no validated screening test exists for the condition and no national registry or reporting exists. Currently, the only treatments for anal dysplasia consist of surgical excision, electro-cautery or laser therapy, but up to 50% of those treated with these current treatments experience recurrence of the disease within one year of treatment and up to nearly 70% within three years of treatment. Therefore, many patients with this condition need multiple treatments. Anal HSIL can lead to HPV-associated squamous cell carcinoma of the anus (SCCA).
Anal cancer is uncommon in the general population, but its incidence is considerably increasing – 64% higher since 1992 — and is higher among women than in men overall and higher in HIV-positive men and women than in HIV-negative persons. The risk of SCCA among HIV-positive men has continued to increase even after the introduction of highly active antiretroviral therapy. Anal cancer is estimated to have 8,300 new cases diagnosed in the United States in 2019.
About VGX-3100
VGX-3100 is a DNA-based immunotherapy under Phase 3 investigation for the treatment of HPV-16 and HPV-18 infection and precancerous lesions of the cervix. Inovio is in open-label Phase 2 clinical trials evaluating its efficacy for treating HPV-related vulvar and anal precancers. VGX-3100 has the potential to be the first approved treatment for HPV infection of the cervix and the first non-surgical treatment for precancerous cervical lesions. VGX-3100 works by stimulating a specific immune response to HPV-16 and HPV-18, which targets the infection and causes destruction of precancerous cells. In a randomized, double-blind, placebo-controlled phase 2b study in 167 adult women with histologically documented HPV-16/18 cervical HSIL (CIN2/3), treatment with VGX-3100 resulted in a statistically significantly greater regression of cervical HSIL and clearance of HPV-16/18 infection vs. placebo. The most common side effect was injection site pain, and no serious adverse events were reported. VGX-3100 utilizes the patient’s own immune system to clear HPV-16 and HPV-18 infection and precancerous lesions without the increased risks associated with surgery, such as loss of reproductive health and negative psychosocial impacts.

Inovio is an innovative biotechnology company focused on the discovery, development, and commercialization of its synthetic DNA technology targeted against cancers and infectious diseases. Inovio’s proprietary technology platform applies antigen sequencing and delivery to enable in vivo protein expression, which can activate potent immune responses to targeted diseases. The technology has been demonstrated to consistently activate robust and fully functional T cell and antibody responses against targeted cancers and pathogens. Inovio’s most advanced clinical program, VGX-3100, is in Phase 3 development for the treatment of HPV-related cervical pre-cancer. Also in development are Phase 2 immuno-oncology programs targeting HPV-related cancers and glioblastoma, as well as externally funded platform development programs in Zika, MERS, Lassa and HIV.
