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

Official title

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

Overview

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).

Interventions

• Dietary supplement Papillex®
  Participants will be instructed to take two capsules twice daily with food, with the first dose taken with the first meal of the day and the second dose taken with the last meal of the day.
• Other Placebo
  Participants will be instructed to take two capsules twice daily with food, with the first dose taken with the first meal of the day and the second dose taken with the last meal of the day.

Primary outcome measures

• The difference in the proportion of participants with cytology improvement [Time frame: Day 0 to 180]

Secondary outcome measures (12)

• The difference in the proportion of participants with cytology improvement [Time frame: Day 0 to 360]
• The difference in the proportion of participants with genotype-specific HPV clearance, [Time frame: Day 0 to 360]
• Change in immune markers (T lymphocytes, interferon (IFN)-β) between Papillex® and placebo [Time frame: Day 0 to 180]
• The difference in the proportion of responders [Time frame: Day 0 to 180, or 360]
• The difference in the proportion of deep responders [Time frame: Day 0 to 180 and 360]
• Concordance between cytology and histology results (where performed as standard of care)* [Time frame: Day 0 to 360]
• Change in micronutrient status [Time frame: Day 0 to 180]
• Change in Symptoms Checklist score between Papillex® and placebo [Time frame: Day 0 to 180]
• Change in Symptoms Checklist score between Papillex® and placebo [Time frame: Day 0 to 360]
• Change in SF-36 Quality of Life (QoL) score between Papillex® and placebo [Time frame: Day 0 to 180]
• Change in SF-36 Quality of Life (QoL) score between Papillex® and placebo [Time frame: Day 0 to 360]
• Incidence of post-emergent adverse events (AE) [Time frame: Day 0 to 360]

Eligibility criteria

Inclusion criteria

• Vasectomized partner, provided that partner is the sole sexual partner and that the vasectomised partner has received medical assessment of the surgical success
• Abstinence
• Histologically confirmed CIN1+ (as per standard of care) with concordant hrHPV positivity at that time, and current abnormal cytology and hrHPV positivity at screening; interval between historical diagnosis and screening must be >6 months OR documented abnormal cytology (LSIL or worse) plus hrHPV positive >6 months prior, and current abnormal cytology with hrHPV positivity at screening
• Willing to provide copies of histology and/or cytology reports for eligibility confirmation
• Agrees to maintain current lifestyle habits (diet, physical activity, medications, supplements, and sleep) as much as possible throughout the study
• Willingness to avoid magnetic resonance imaging, computed tomography, X-ray, or other procedures with contrast media injection for 48 hr prior to study visits assessing micronutrient status
• Willingness and ability to complete questionnaires and diaries associated with the study, and to complete all clinic visits and assessments
• Provided voluntary, written, informed consent to participate in the study
• Otherwise healthy as determined by medical history and laboratory results as assessed by Qualified Investigator (QI)

Exclusion criteria

• Women who are pregnant, breast feeding, or planning to become pregnant during the study
• Allergy, sensitivity, or intolerance preventing consumption of investigational product or placebo ingredients
• Currently undergoing treatment for CIN, are indicated for treatment during the study period, have received treatment (e.g., conization or loop electrosurgical excision procedure) within the last five years, or have active CIN 3
• Concurrent uterine pathologies
• History of hysterectomy or destructive therapy of the cervix
• Cervical cancer
• Unstable metabolic disease or chronic diseases as assessed by the QI
• Current or history of any significant diseases of the gastrointestinal tract as assessed by the QI
• Unstable hypertension. Treatment on a stable dose of medication for at least 3 months will be considered by the QI (See Section 7.3)
• Significant cardiovascular event in the past 6 months. Participants with no significant cardiovascular event on stable medication may be included after assessment by the QI on a case-by-case basis
• History of or current diagnosis with kidney and/or liver diseases as assessed by the QI on a case-by-case basis, with the exception of history of kidney stones in participants who are symptom free for 6 months
• Self-reported confirmation of current or pre-existing thyroid condition. Treatment on a stable dose of medication for at least 3 months will be considered by the QI
• Major surgery in the past 3 months or individuals who have planned surgery during the course of the study. Participants with minor surgery will be considered on a case-by-case basis by the QI
• 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
• Individuals with an autoimmune disease or are immune compromised
• Self-reported confirmation of a HIV-, Hepatitis B- and/or C-positive diagnosis as assessed by the QI
