What this trial studies

This multi-centre, randomized, double-blind, placebo-controlled study aims to assess the effectiveness of AHCC®, a standardized extract from Lentinula edodes mycelia, in clearing high-risk human papillomavirus (HR-HPV) infections in female participants. The study focuses on women diagnosed with persistent HR-HPV infections and low-grade squamous intraepithelial lesions (LSIL). Participants will receive either AHCC® capsules or a placebo for a specified duration, with the primary outcome being the clearance of HR-HPV infections. The study builds on preliminary data suggesting that AHCC® may enhance immune response and support the elimination of HPV infections.

Who should consider this trial

Good fit: Ideal candidates for this study are premenopausal women with a documented history of persistent HR-HPV infections and low-grade squamous intraepithelial lesions.

Not a fit: Patients with a recent history of serious cardiovascular conditions or those who are menopausal may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new therapeutic option for women with persistent HR-HPV infections, potentially reducing the risk of cervical cancer.

How similar studies have performed: Preliminary studies on AHCC® have shown promising results in clearing HR-HPV infections, indicating potential success for this approach.
