Inovio Ends Enrollment In Anal Dysplasia Study On VGX-3100

Inovio Pharmaceuticals, Inc. (NASDAQ:INO) announced that it has completed enrollment in a phase II study evaluating its lead HPV immunotherapy — VGX-3100 — for the treatment of anal dysplasia caused by human papillomavirus (HPV). The study will assess the efficacy and safety of VGX-3100 in 24 adult men and women with anal high-grade squamous intraepithelial lesions (anal HSIL). Preliminary efficacy data from the study is expected to be announced later this year.

Anal HSIL can often lead to HPV-associated squamous cell carcinoma of the anus (SCCA).

Notably, surgical excision, electro-cautery or laser therapy are the only forms of treatment available for patients with HPV-related anal dysplasia. However, half of these patients experience recurrence of the disease within one year of treatment and approximately 70% within three years of treatment, thereby requiring multiple treatment and repeated surgeries.

If approved, Inovio will be able to address this unmet medical need, which could effectively eliminate or delay surgery for the given patient population.

Shares of Inovio were up 2.5% following this news on Monday. However, the stock has plunged 39.3% so far this year wider than the industry’s decline of 2.1%.
