We developed an HPV16 E7-expressing Lactobacillus-based therapeutic vaccine, IGMKK16E7, to elicit mucosal E7-specific TH1 cellular immune responses. This study aims to examine the safety and clinical efficacy of IGMKK16E7 on HPV16-positive high-grade squamous intraepithelial lesion (HSIL). This is a multicenter, placebo-controlled, double-blind randomized phase I/II trial to test the safety and efficacy of IGMKK16E7 against HPV16-positive HSIL. The groups will include placebo, low-dose (0.5 g/day), middle-dose (1 g/day), and high-dose (1.5 g/day) IGMKK16E7. The target sample size will be 41 patients per group, and our data on our former agent, GLBL101c, were used to calculate sample size for 70% power and an α level = 0.05. The primary endpoint is IGMKK16E7 safety and pathological regression at week 16, and the secondary endpoints are cytological regression and HPV16 E7 immunological response. This study protocol has been approved by the Japanese Pharmaceuticals and Medical Devices Agency. Patient enrollment will begin in May 2019.
