A Clinical Trial to Investigate the Safety and Efficacy of Papillex® on Abnormal Cervical Cells Caused by HPV.

March 3, 2026 updated by: Papillex Inc.

A Randomized, Triple-blind, Placebo-controlled, Parallel Clinical Trial to Investigate the Safety and Efficacy of Papillex® on Abnormal Cervical Cells Caused by HPV

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).

  14. Cancer, except skin basal cell carcinoma completely excised with no chemotherapy or radiation with a follow up that is negative. Volunteers with cancer in full remission for more than five years after diagnosis are acceptable
  15. Individuals with an autoimmune disease or are immune compromised
  16. Self-reported confirmation of a HIV-, Hepatitis B- and/or C-positive diagnosis as assessed by the QI
