NCT Number: NCT06979180

A 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).

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

  • Alcohol or drug abuse within the last 12 months
  • Current use of prescribed and/or over-the-counter (OTC) medications, supplements, and/or consumption of food/drinks that may impact the efficacy and/or safety of the investigational product (Section 7.3)
  • Clinically significant abnormal laboratory results at screening as assessed by the QI
  • Blood donation 30 days prior to baseline, during the study, or a planned donation within 30 days of the last study visit
  • Participation in other clinical research studies 30 days prior to baseline, as assessed by the QI
  • Individuals who are cognitively impaired and/or who are unable to give informed consent
  • Any other condition or lifestyle factor, that, in the opinion of the QI, may adversely affect the participant's ability to complete the study or its measures or pose significant risk to the participant
