MILACLE study
【Scientific Title】
A Phase I/II study of mucosal immunotherapy using HPV-targeting Lactobacillus-based vaccine, IGMKK16E7, for treatment of HPV16-related high-grade squamous intraepithelial lesions: MILACLE study
【Region】
Japan
【Condition】
High-grade squamous intraepithelial lesions (HSIL/CIN2-3)
【Narrative Objectives】
To evaluate the safety of oral administration with IGMKK16E7 to patients with
HSIL/CIN2-3 and decide the recommended human dose to obtain the optimal efficacy.
【Basic objectives -Others】
To examine the relationship between HPV E7 expression levels and the efficacy of IGMKK16E7.
【Primary outcomes】
A safety of IGMKK16E7 and pathological regression of HSIL/CIN2-3.
【Key secondary outcomes】
TH1 immune responses to E7, cytological regression of /CIN2-3, and Clearance of HPV genome.

Type of intervention/MedicineVaccine
Interventions/Control_1/
Low-dose of IGMKK16E7 (an attenuated HPV16E7-expressing Lactobacillus casei) is administered daily. All patients received four rounds of oral vaccination at weeks 1, 2, 4,
and 8. Each dose of IGMKK16E7 or placebo is administered orally once each morning after
fasting for five days each treatment week.
Interventions/Control_2/
Middle-dose of IGMKK16E7 (an attenuated HPV16E7-expressing Lactobacillus casei) is administered daily. All patients received four rounds of oral vaccination at weeks 1, 2, 4,
and 8. Each dose of IGMKK16E7 or placebo is administered orally once each morning after fasting for five days each treatment week.
Interventions/Control_3/
High-dose of IGMKK16E7 (an attenuated HPV16E7-expressing Lactobacillus casei) is administered daily. All patients received four rounds of oral vaccination at weeks 1, 2, 4,
and 8. Each dose of IGMKK16E7 or placebo is administered orally once each morning after
fasting for five days each treatment week.
Interventions/Control_4/
Placebo is administered daily. All patients received four rounds of oral vaccination at weeks 1, 2, 4, and 8. Each dose of IGMKK16E7 or placebo is administered orally once each morning after fasting for five days each treatment week.
