Cryotherapy VS. Nitric-zinc Complex in the Treatment of Plantar Warts.

Status Not yet recruiting

Clinical Trial Summary

Plantar warts are benign skin lesions caused by human papillomavirus (HPV).There are several treatment methods for this illness, but none of them can heal all patients. Cryotherapy using liquid nitrogen is one of the most common local treatments. In this study, we will compare the effectiveness of cryotherapy with liquid nitrogen with the association of organic acids and nitric acid (nitric-zinc complex). In addition, as secondary objectives have been defined: 1) know the number of applications necessary for each treatment to achieve the complete resolution of the plantar wart, in order to compare the healing times between each treatment and establish which treatment is faster, 2) analyze the influence of the HPV biotype, the location of the lesion and the time of evolution in the response to the different treatments, and 3) Compare the ultrasound signs of plantar warts with the ultrasound signs of healthy skin after the resolution of the process.

Clinical Trial Description

A randomized controlled clinical trial is proposed. The recruitment of patients will be carried out by including the sample of those patients who have diagnostic confirmation of plantar wart in the Chiropodology and Surgery Service of the University Podiatry Clinic of the Complutense University of Madrid, consecutively, between November 2020 and the date when the estimated sample size is reached. Participants in the trial will be assigned with equal probability to each treatment arm, based on their consecutive inclusion in the study. Subsequently, the treatment allocation will be determined by a random code generated by the Epidat 4.1 program using random permuted blocks. The treatment used will be evident both for the participant and for the research podiatrist responsible for the intervention. However, the primary result will be confirmed by the microbiological study carried out by the Department of Microbiology of the Complutense University of Madrid, which does not know any data about the patient or the treatment group to which it was initially assigned. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
