This clinical trial is focused on studying the effectiveness of the nonavalent HPV vaccine, known as Gardasil 9, in treating difficult-to-treat palmar or plantar warts. These warts are located on the palms of the hands or the soles of the feet and can be challenging to treat. The study aims to see if the vaccine can lead to the complete disappearance of these warts in patients who have not had success with at least two previous treatments.
Participants in the study will receive the Gardasil 9 vaccine, which is designed to protect against nine types of the Human Papillomavirus (HPV). The vaccine will be compared to a placebo to determine its effectiveness. The study will involve a series of injections over a period of several months, with the goal of observing the complete remission of warts one month after the third injection. The study will also monitor the quality of life, pain levels, and any changes in the number of warts over time.
The trial is intended for individuals who have had palmar or plantar warts for more than a year and have tried at least two other treatments without success. The study will last for several months, and participants will be regularly assessed to track the progress of their warts and any improvements in their condition. The ultimate goal is to determine if the nonavalent HPV vaccine can be an effective treatment option for these persistent warts.
