Brief Summary
The zinc monoterpenoid tetra-ascorbo-camphorate possesses broad-spectrum anti-viral properties in vitro, particularly against HIV, HSV and HPV. Its C14 formulation could be a promising candidate for in vivo clinical evaluation as a potential microbicide or therapeutic drug. The aim of this clinical trial is to determine whether C14 is effective in reducing the genital viral load of HR-HPV and in treating low-grade dysplastic lesions of the cervix. It will also determine the tolerability of C14. The main questions to be answered by the clinical trial are as follows: Does C14 reduce the genital HR-HPV viral load in participants with persistent HR-HPV infections? What medical problems do participants experience when taking C14? Researchers will compare C14 to a placebo (a similar substance that contains no drug) to see if C14 is effective in reducing genital C14 viral load and in treating low-grade dysplastic lesions of the cervix. Participants will receive four monthly treatments (5ml of C14 dissolved in distilled water administered twice daily \[morning and evening\] for seven days via vaginal syringe during the follicular phase) of C14 or placebo for 4 months and visit the clinic once every 2 weeks for examinations and tests. They will keep a diary of their symptoms and the number of times they keep the hospital appointment.

Study Arms (2)
C14 arm
EXPERIMENTALIn this arm, particpants will received by vaginal syringe, 5ml of 1% C14, twice a day for 7 days, starting the first cure during the follicular phase of the cycle, just after the last menstrual period (S1), the second cure the following month (S5), the third cure 4 weeks later (S9) and the last cure 8 weeks later (S13).
Control arm
PLACEBO COMPARATORIn this arm, particpants will received by vaginal syringe, 5ml of distilled water, twice a day for 7 days, starting the first cure during the follicular phase of the cycle, just after the last menstrual period (S1), the second cure the following month (S5), the third cure 4 weeks later (S9) and the last cure 8 weeks later (S13).
Interventions
The trial phase will consist of hospital administration by vaginal syringe of 5ml of 1% C14, twice a day for 7 days, starting the first cure during the follicular phase of the cycle, just after the last menstrual period (S1), the second cure the following month (S5), the third cure 4 weeks later (S9) and the last cure 8 weeks later (S13). Gynaecological follow-up with HPV molecular testing and cervical smear will be performed two days after each course of treatment at S2, S6, S10, S14 and 2 weeks after the last course of treatment (S16). Unprotected sexual intercourse will not be permitted during each course of treatment, and for at least 72 hours before each genital swab.
Instead of C14, distilled water will be administered in this group.
