Hydrogel Blister Patch Prototype Treatment for Foot Blisters on the Heel

Feasibility Study to Evaluate the Safety and Performance of a Hydrogel Blister Patch Prototype for the Treatment of Foot Blisters

Study to evaluate the safety and performance of a new blister patch intended to treat blisters on the heel of the foot.

Study Overview

• Status: Completed
• Conditions: Blister
• Intervention / Treatment: Device: Experimental Blister Patch; Device: Marketed Pflaster

Detailed Description

The study will require participation for up to 14 days of participation or less if the blister heals sooner, will recruit 100 subjects with fluid filled blisters on the heel of the foot that are intact and not broken. Some subjects will be asked to have their blisters photographed. All subjects will be required to have their blister unroofed (top layer of skin removed by the physician using sterile instruments). All subjects will receive study product, either test product or a marketed product.

• Females of childbearing potential must be using a medically-acceptable method of birth control for at least one month prior to Visit 1 such as the ones listed below and agree to continue using this method during their participation in the study; Note that abstinence is not an approved method of birth control.

  • Postmenopausal or amenorrheic for one year
  • Surgically sterile (hysterectomy, tubal ligation, or oophorectomy)
  • Use of an effective method of birth control (e.g. prescription oral contraceptives, contraceptive implants or injections, intrauterine device, diaphragm, cervical cap or condoms with spermicide)
• Individuals exhibit a blister on the heel that is determined by the investigator to be no more than 72 hours old and in stage 2

• Subject is willing and able to follow the study directions, to participate in the study, and to return for all specified visits

Exclusion Criteria:

• Pregnant, planning a pregnancy or actively nursing
• Exhibits a foot blister on the heel that exceeds 1125mm2 or would otherwise not be covered by the hydrogel portion of the study product
• Unstable or uncontrolled medical conditions that could require intensive treatment during the course of the study
• Individuals with autoimmune disorders including, but not limited to, lupus erythematosus, rheumatoid arthritis, or HIV/AIDS
• Currently participating in or, within the past 30 days have participated in another clinical study using an investigational drug or device
• Employees of the site, or friends/relatives of employees that would have access to study information
• Diabetic, type I or type II
