Clinical Trial Summary

To investigate the use of self-administered artesunate vaginal pessaries as treatment for cervical precancer in low and middle-income countries (LMIC). The central hypothesis of this study is that self-administered intravaginal Artesunate will be safe, and result in a clinical response among both HIV-positive and HIV-negative women with cervical precancer in LMICs.

Description:

Despite being preventable, cancer of the cervix is a leading cause of cancer death in Kenya and other low- and middle-income countries (LMIC). Cervical cancer can be prevented if early changes in the cervix, called cervical precancer, are detected through screening, and adequately treated. Cervical precancer treatment includes a surgical procedure called Loop Electrosurgical Excision Procedure (LEEP), which removed the involved area of the cervix.

In countries like Kenya, this LEEP procedure is only available in referral hospitals which have trained consultants, and hence is difficult to access for most women who live in rural areas and away from tertiary facilities. Additionally, the LEEP procedure also increases the chance of a woman not being able to carry a pregnancy to full term, because the cervix is shorter after the procedure. For these reasons, alternative treatments, including self-administered treatments such as Artesunate are being investigated as alternative cervical precancer treatment that can be self-administered.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	the type, frequency, severity and duration of adverse events	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.	From the first day of the study treatment to week 14 ( 8 weeks after artesunate use)
Secondary	Adherence	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.	From the first day of the study treatment to week 14 ( 8 weeks after artesunate use)
Secondary	Change in lesion	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.	From the first day of the study treatment to week 24
Secondary	Histologic regression	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.	From the first day of the study treatment to week 24
Secondary	Acceptability	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.	At week 8
