Candin for the Treatment of Common Warts
- Conditions
- Common Warts (Verruca Vulgaris)
- Interventions
- Drug: Candin, Intradermal SolutionDrug: Placebo
- Registration Number
- NCT05889845
- Lead Sponsor
- Nielsen BioSciences, Inc.
- Brief Summary
The goal of this clinical trial is to compare outcome in healthy subjects 12 years of age and older with at least 3, but no more than 20, common warts (Verruca vulgaris) following treatment with Candin or placebo. The main questions it aims to answer are:
* does treatment with Candin result in better clearance of warts than placebo
* how many injections are required to result in wart clearance Participants will
* have one wart selected for injection every two weeks until clearance
* return 12 weeks after wart clearance for assessment of durability of response
- Detailed Description
This study involves a comparison of an equal volume injection of Candin with an injection of placebo (unpreserved normal saline solution) in common warts. Subjects will be randomized 2:1 to receive Candin or placebo. During the Treatment Period, 1 dose (0.5 mL) of investigational product (IP) will be injected every 2 weeks into a single treatment wart until either clinical clearance of the treatment wart is achieved or a total of 10 injections have been administered.
Subjects achieving clinical clearance of the treatment wart will receive a final injection at the site of the cleared wart and then immediately enter the Observational Period for 12 weeks. Complete resolution is achieved when a subject demonstrates clinical clearance for 12 weeks.

Group Intervention Description Candin treatment Candin, Intradermal Solution Candida albicans Skin Test Antigen for Cellular Hypersensitivity will be administered as a 0.5 mL injection at the region of the interdigitated base of the treatment wart (epidermal/dermal junction) every 2 weeks for up to 10 injections Placebo Placebo Matching placebo (sterile saline) will be administered as a 0.5 mL injection at the region of the interdigitated base of the treatment wart (epidermal/dermal junction) every 2 weeks for up to 10 injections
- Primary Outcome Measures
Name Time Method Number of participants with complete resolution of the treatment wart Twelve weeks after last injection Absence of visual or measurable wart maintained through the entire Observational Period for injected wart
- Secondary Outcome Measures
Name Time Method Time to wart clearance Up to 27 weeks Time from first injection to achieving clinical clearance of the treatment wart. Clinical clearance is no evidence of the wart by visual inspection.
Number of participants with clinical clearance of at least 50% of all measured warts Up to 27 weeks The injected wart and up to five other warts will be measured. Clinical clearance is no evidence of the wart by visual inspection.
Number of participants with clinical clearance of all measured warts Up to 27 weeks The injected wart and up to five other warts will be measured. Clinical clearance is no evidence of the wart by visual inspection.
Time to clinical clearance of all measured warts Up to 27 weeks The injected wart and up to five other warts will be measured. Clinical clearance is no evidence of the wart by visual inspection.
