HPV Infections

The EQUIP Study is testing whether high-risk human papillomavirus (hrHPV), the virus that causes most cervical cancers, can be accurately detected from menstrual blood collected at home. People who have been referred for colposcopy after an abnormal Pap or hrHPV test will use the Q-Pad Kit during their period to collect menstrual samples on a special menstrual pad and mail them to a central laboratory for hrHPV testing. The same participants will have a standard cervical sample collected for routine hrHPV testing and will undergo colposcopy as part of their usual care. By comparing hrHPV results from menstrual samples with results from cervical samples and biopsy findings, the study will evaluate how well the Q-Pad hrHPV Test System detects cervical precancer and will also assess how easy and acceptable it is for participants to use this at-home collection method.

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.
