An Exploratory Safety and Immunogenicity Study of HPV16+ Immunotherapy VB10.16 in Women With HSIL; CIN 2/3)

The study will be divided into two phases, a dosing and expansion phase.

During the dosing phase the safety, tolerability and immunogenicity of 2 different vaccination schedules of 3 mg VB10.16 immunotherapy will be established in a minimum of 12 patients with histology confirmed CIN 2.

During the expansion phase the safety, tolerability and immunogenicity of the selected vaccination schedule will be evaluated in approximately 15 to 20 patients with histology confirmed HPV16+ CIN 2/3.
