About
Combination immune checkpoint inhibitor and DNA vaccine will result in clearance of HPV DNA biomarkers (oral and/or plasma) for patients with persistent HPV-16 E6/E7 DNA (HPV biomarker) after treatment with curative intent.
Full description
Objectives:
Primary Objectives:
To determine whether combination immune checkpoint inhibitor, alone or together with a DNA vaccine will result in clearance of HPV biomarkers for patients at risk of disease progression.
Secondary Objective(s):
- To evaluate the time to progression among patients with detectable HPV DNA when treated with the durvalumab/MEDI0457 versus durvalumab monotherapy versus observation.
- To assess the toxicity of durvalumab and MEDI0457 in the adjuvant setting.
Exploratory Objective(s):
- To determine whether anti-PD-L1 alone or together with an HPV DNA vaccine will enhance HPV E6/E7-specific and/or mutation-associated neoantigen (MANA)-specific T cell responses and whether these responses correlate with enhanced clearance of HPV as measured by DNA in oral rinses and/or plasma.
- To determine whether anti-PD-L1 alone or together with an HPV DNA vaccine will enhance HPV 16 E6/E7-specific IgG and whether these responses correlate with enhanced clearance of HPV as measured by DNA in oral rinses and/or plasma
