简要总结
This study will test the efficacy and safety of different routes of administration of a DNA vaccine in patients with HPV16+ CIN2/3. Subjects will be enrolled in one of six treatment groups. Subjects enrolled in the first two groups will receive vaccination intradermally with a needle-free delivery device. Subjects enrolled in groups 3 and 4 will receive vaccination intramuscularly. Subjects enrolled in groups 5 and 6 will receive vaccine intralesionally.
详细描述
Primary Objectives
- To evaluate the feasibility and toxicity of vaccination in women with CIN2/3 caused by HPV16
- To evaluate the effect of vaccination on histology
- To compare immunogenicity of three different routes of administration: intradermal (ID), intramuscular (IM), intralesional (IL).
Secondary Objectives:
- To evaluate changes in HPV viral load
- To evaluate the cellular immune response to vaccination
- To evaluate the humoral immune response to vaccination
- To evaluate local tissue immune response
- To correlate measures of immune response with clinical response
- To correlate measures of immune response with those observed in the preclinical model
