Study summary

The goal of this clinical trial is to investigate the safety and efficacy of Papillex® on the regression of abnormal cervical cells caused by HPV in women with a cervical intraepithelial neoplasia (CIN) 1 or 2 diagnosis. The main question it aims to answer is:

Is there a difference in the proportion of participants with a regression in CIN based on histology or cytology from baseline at day 180 between Papillex® and placebo?

Participants will be asked to consume Papillex® or placebo for 180 days, complete questionnaires, a PAP smear, HPV test, and colonoscopy (where applicable).
