Is this trial a fit for you?
✓Likely a good fit
Women aged 25–55 with a confirmed diagnosis of CIN 1 or CIN 2 who meet the study's contraception or non-childbearing criteria are the intended participants.
✕Probably not a fit
People with more advanced disease (for example CIN 3 or invasive cervical cancer), pregnant women, or those unable to follow the 180-day treatment and follow-up plan are unlikely to benefit from this trial.

What this trial studies
This interventional, placebo-controlled trial gives participants either Papillex® or a matching placebo to take for 180 days. The main outcome is the proportion of participants with regression of cervical intraepithelial neoplasia (CIN) on histology or cytology at day 180 compared with baseline. Participants will have Pap smears, HPV testing, questionnaires, and where applicable a colposcopy to document changes. Safety will be monitored through adverse event reporting and scheduled follow-up visits.
Why it matters
Potential benefit: If successful, Papillex® could enable non-surgical regression of abnormal cervical cells and reduce the need for invasive procedures.
How similar studies have gone: Previous studies of non-surgical treatments for CIN have shown mixed results, and Papillex® has not yet been established as effective in large trials.

Treatment on a stable dose of medication for at least 3 months will be considered by the QI (See Section 7.3) 10. 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 11. 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 12. 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 13. 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 14.
