Feasibility of Intravaginal Artesunate as Adjuvant HPV & Cervical Precancer Treatment in Kenya

Feasibility of Intravaginal Artesunate as Adjuvant HPV & Cervical Precancer Treatment Among Women Living With HIV in Kenya

The objective of this randomized, placebo-controlled trial is to evaluate whether intravaginal artesunate pessaries (vaginal inserts) can be used as adjuvant therapy following thermal ablation to improve Human papillomavirus (HPV) treatment outcomes in Women Living with Human Immunodeficiency Virus (WLWH).

The study will evaluate whether women who use artesunate will have higher HPV clearance at 6 months, compared to those who used a placebo. The study will also assess the safety, adherence, and acceptability of this treatment. 120 participants will be enrolled in the study. Participants will self-administer the study drug nightly for 5 days, take a week off, and repeat twice (use study drug on weeks 1, 3,5) and will return to the clinic on weeks 2, 4, 6, 12, and week 24 for follow-up.

WLWH face up to six times increased risk of cervical cancer, as a result, cervical cancer is a leading cause of death in this population. Cervical cancer is caused by persistent infection with the human papillomavirus (HPV), resulting in precancerous changes that if not adequately treated, progress to cancer. Thermal ablation is a commonly used treatment for cervical precancer in Kenya and other low- and middle-income countries (LMICs). Current treatments for HPV or cervical precancer, including thermal ablation, are associated with high rates of treatment failure in WLWH. In a recent study from Zambia, only 44% of WLWH had cleared HPV at six months following thermal ablation treatment. Other studies have demonstrated up to 30% recurrence rate of high-grade cervical precancer at 12 to 24 months after treatment. Persistent infection with HPV following precancer treatment is a key risk factor for treatment disease recurrence.
