Clinical Trial: Therapeutic Vaccination for Patients With HPV16+ Cervical Intraepithelial Neoplasia (CIN2/3)

Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Interventional

Official Title: A Pilot Study of pnGVL4a-CRT/E7 (Detox) for the Treatment of Patients With HPV16+ Cervical Intraepithelial Neoplasia 2/3 (CIN2/3)

Brief Summary: 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.

Detailed Summary:

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
