E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary Objectives:
- To investigate the efficacy of imiquimod 5% cream for the treatment of CIN2-3 lesions, compared to LLETZ treatment, in selected populations

|
E.2.2 | Secondary objectives of the trial |
Secondary Objectives:
- To assess the incidence and severity of side effects of imiquimod therapy, compared to LLETZ treatment.
- To assess cytological disease recurrence at 6, 12 and 24 months follow-up, for both treatment groups.
- To assess Quality of life (QoL) before, during and after treatment for both treatment groups.

E.5 End points |
E.5.1 | Primary end point(s) |
1. Regression-or-not of CIN2 or CIN 3 lesions after imiquimod therapy defined as regression to CIN 1 or less, at 20 weeks follow-up and adequate treatment of high-grade CIN by LLETZ, defined as no need for additional treatment within 6 months.
2. A prediction model for treatment efficacy of imiquimod in the individual patient, based on biomarkers reflecting host, virus and cellular factors. |
