Brief 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).

Outcome Measures
Primary Outcomes (1)
The difference in the proportion of participants with cytology improvement
The difference in the proportion of participants with cytology improvement defined as improvement by ≥1 Bethesda category on Pap smear (e.g., HSIL→LSIL/NILM; LSIL→NILM) from baseline at day 180 between Papillex® and placebo.
Day 0 to 180
Secondary Outcomes (12)
The difference in the proportion of participants with cytology improvement
Day 0 to 360

Eligibility Criteria
You may qualify if:
- Females between 25 and 55 years of age
- Females not of child-bearing potential, defined as those who have undergone a permanent sterilization procedure (e.g. hysterectomy, bilateral oophorectomy or bilateral tubal occlusion) or have been post-menopausal for at least 1 year prior to screening Or,
- Individuals of child-bearing potential must have a negative baseline urine pregnancy test and agree to use a medically approved method of birth control for the duration of the study. All hormonal birth control must have been in use for a minimum of three months. Acceptable methods of birth control include:
- Hormonal contraceptives including oral contraceptives, hormone birth control patch (Ortho Evra), vaginal contraceptive ring (NuvaRing), injectable contraceptives (Depo-Provera, Lunelle), hormone implant (Norplant System) or intrauterine hormone-releasing system
- Double-barrier method
- Intrauterine devices
- Non-heterosexual lifestyle or agrees to use contraception if planning on changing to heterosexual partner(s)
- 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 \>12 months OR documented abnormal cytology (LSIL or worse) plus hrHPV positive \>12 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
- +1 more criteria
You may not qualify if:
- 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
