Intravaginal artesunate pessaries for treatment of cervical intraepithelial neoplasia 2/3 among HIV-positive and HIV-negative women in Kenya: Study protocol for a pilot trial.

Background: Cervical cancer disproportionately affects women in low- and middle-income countries (LMICs), which bear 90% of deaths. Current precancer treatments rely on healthcare workers who may be out of reach for many women. Development of a patient-controlled cervical precancer treatment can significantly improve access in remote areas and promote secondary prevention of cervical cancer.
Methods: This is a phase I trial among 18 HIV-positive and HIV-negative women in Kenya, investigating use of artesunate vaginal pessaries as treatment for cervical precancer among women screening positive for cervical precancer who need excisional treatment. The primary objective will be the safety of self-administered artesunate pessaries. Participants will self-administer 200mg of artesunate vaginally daily for 5 days, followed by a drug-free week, repeated for a total of 4 cycles (artesunate self-administration on weeks 1, 3, 5, 7). The total study duration, including participant follow-up is 48 weeks. Safety and adherence will be assessed through review of symptom diaries and biweekly follow-ups during the treatment phase. Data analysis will include quantitative and qualitative methods. Figure 1 illustrates the study schema.
Discussion: Considering the challenges associated with excisional treatments for cervical precancer in LMICs where access to care is limited, this study proposes an alternative approach using intravaginal Artesunate. This clinical trial will provide important safety and efficacy data on using artesunate as a topical therapy for both HIV-positive and HIV-negative women.
