CIN 2/3

This prospective, multicenter cohort study will recruit eligible HPV16/18-positive women from three tertiary hospitals in China. Peripheral blood samples and clinical data (cytology, HPV genotyping, colposcopy-directed biopsy) will be collected, followed by standardized mass cytometry (CyTOF) to develop and evaluate an immune model across cervical lesion grades.

This is a phase II double blind, placebo-controlled, randomized study of Artesunate vaginal inserts for the treatment of women who have cervical high grade intraepithelial neoplasia (CIN2/3).

NeoART-CIN is a Phase II clinical study evaluating the safety and effectiveness of oral artesunate in patients with pre-cancerous cervical intra-epithelial neoplasia (CIN2/3), to investigate if a course of treatment with oral artesunate can reverse pre-cancerous changes in the cervix and prevent the development and progression of invasive cancer. Findings from this study will increase our understanding of the effects of artesunate on CIN2/3 and if confirmatory inform future clinical studies.

Given that WLWH are more likely to develop persistent HPV infection and CC, effective screening and the management and treatment of pre-cancerous cervical abnormalities is critical to decrease the global burden of cervical cancer. The vast majority of WLWH live in SSA, where resources are more constrained. Therefore, simple, affordable, and effective tools are needed for the prevention of cervical cancer in SSA. In this setting, the best method for treatment of screen-positive WLWH has not been determined. The proposed study will compare the effectiveness of TA vs. LEEP, for treating precursor lesions (CIN 2/3) and HPV infection in WLWH, identify the determinants of treatment failure, and develop a strategy to predict patients in whom treatment is likely to fail so that alternative treatments can be provided. Moreover, local evidence of the optimal method of treatments is necessary to inform health policy and promote adherence.

Imiquimod is a good non-invasive treatment option for women with cervical high-grade squamous intraepithelial neoplasia (cHSIL), especially those with a possible (future) pregnancy wish. Complete response to imiquimod occurs in 55-73% of patients, however side-effects of imiquimod are common and can be extensive. Therefore, biomarkers which can predict response to imiquimod therapy are warranted, to increase therapy efficacy and to avoid side effects in patients who will not respond. This prospective, multi-center cohort study aims to validate the potential of immune related biomarkers to predict the clinical response of patients with primary cHSIL to imiquimod, aims to explore the value of these immune biomarkers in recurrent/residual cHSIL to predict treatment responses for imiquimod and aims to explore their potential in spontaneous regression of cHSIL (CIN2).

The study aims to evaluate whether organised, concomitant HPV vaccination and HPV screening offered to all resident women aged 22-27 will result in a more rapid elimination of HPV infection in Sweden. This objective will be examined at the population level.
