What this trial studies

This clinical trial evaluates the feasibility of a larger study on the effects of a Carrageenan mouthwash in preventing oral HPV infections. Participants aged 18 to 45 who are sexually active will complete a baseline visit, including a questionnaire and an oral rinse sample for HPV testing. They will receive mouthwash and instructions for use, followed by bi-weekly follow-ups for six months to report on mouthwash usage and sexual activities. The study is designed to be placebo-controlled and triple-blind to ensure unbiased results.

Who should consider this trial

Good fit: Ideal candidates are sexually active individuals aged 18 to 45 who reside in Montreal and have engaged in oral sex in the past month.

Not a fit: Patients who have been previously vaccinated against HPV or have a history of mouth or throat cancer may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new preventive measure against oral HPV infections, potentially reducing the risk of related cancers.

How similar studies have performed: While this approach is novel, similar studies exploring preventive measures for HPV have shown promise, indicating potential for success.
