Artesunate Pessaries (Vaginal Inserts) for Cervical Precancer in Kenya

Safety will be assessed by evaluating the type, frequency, severity, and duration of adverse events (AEs) using the U.S National Cancer Institute Common Terminology Criteria for Adverse Events, v5.0 (CTCAE 5.0).

The NCI Common Terminology Criteria for Adverse Events is a descriptive terminology that can be utilized for Adverse Event (AE) reporting. A grading (severity) scale is provided for each AE term. Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local, or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living (ADL). Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL. Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE.

Adherence will be evaluated based on participant self-report, returned packaging for used pessaries, and inspection of vaginal applicators under ultraviolet light for evidence of intravaginal insertion. A participant will be considered adherent if both methods support use of 80% (16 of 20) of the pessaries.

Change in lesion size will be assessed by comparing colposcopic images of cervical lesions at baseline compared to the time of excision or week 24, whichever comes earlier, noting changes in the number and size of lesions and cervical quadrants involved. Blinded before and after treatment images will be evaluated by two gynecologists not involved in the study for evidence of a reduction in lesion size (Yes/No). A third gynecologist will be used as a tiebreaker if the two do not agree. The difference in proportions with the reduction in lesion size between the HIV-positive and HIV-negative groups will be reported.

Histologic regression will be evaluated by comparing the initial diagnostic biopsy at study entry with the exit biopsy or excisional specimen final diagnosis. Participants who have complete regression at follow-up will have a confirmatory biopsy at the lesion site which will be used for final diagnosis. Regression will be defined as CIN1 or less in the resection or biopsy specimen. All specimens will be reviewed by a pathologist in-country and slides scanned for review by a 2nd pathologist at UNC. A 3rd pathologist will be utilized for consensus if the first two pathologists disagree. The difference in proportions with the histologic regression between the HIV-positive and HIV-negative groups will be reported.

Acceptability will be assessed using a questionnaire with study participants using Artesunate. Responses to questions will be graded on a Likert scale. The Likert scale has questions from 1 to 6. Higher scores represent better QOL.
