February 15, 2022 updated by: Iltefat Hamzavi, Henry Ford Health System

A Prospective, Randomized, Controlled Clinical Trial Comparing the Efficacy Carbon Dioxide (CO2) Laser Excision Versus Surgical Deroofing in the Treatment of Hidradenitis Suppurativa

This study compares two well-known treatment options for Stage 2 hidradenitis suppurativa: carbon dioxide (CO2) laser excision versus surgical deroofing.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  • We will be treating patients with Stage 2 (interconnected sinus tracts and nodules) hidradenitis suppurativa who have somewhat active involvement (including drainage) in the axillae. We will only be treating ONE axilla per patient.
  • After patients are screened and deemed appropriate candidates, they will be randomized to a treatment group: CO2 laser excision or surgical deroofing.
  • For each patient, there will be a single intervention (either CO2 laser excision or surgical deroofing), after which there will be 5 planned follow-up appointment at following intervals: 1 week, 2 weeks, 4 weeks, 3 months, 6 months. This will take place over course of 6 months for each patient.
  • During the study, subjects will be asked to provide information on quality of life measures, and filling out questionnaires (DLQI and Skindex29) at each visit.

  • Inclusion criteria:

    1. Be at least 13 years old and have a diagnosis of hidradenitis affecting the underarms.
    2. Agree to follow and undergo all study-related procedures, and follow-up over six month period.

  • Exclusion criteria:

    1. Patients who have already undergone surgical excision to affected area.
    2. Patients who are pregnant or breast feeding will not be able to take part in the study due to the unknown effects of CO2 laser in pregnant females, as well as risk of lidocaine use during pregnancy and breastfeeding
    3. Patients with a history of allergy to lidocaine or topical anesthetics will not be able to take part in this study.
    4. Patients with a history of vitiligo as the CO2 laser may cause new spots of depigmentation.
    5. Patients with a pacemaker/defibrillator in place.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

13 years to 100 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Be at least 13 years old
  2. Be otherwise healthy
  3. Have a diagnosis of HS
  4. Patients must have Hurley Stage II HS affecting the axilla, with one or more widely separated recurrent abscesses, with formation of a sinus tract and/or scarring
  5. Be able to understand the requirements of the study, the risks involved, and be able to sign the informed consent form
  6. Agree to follow and undergo all study-related procedures
  7. If applicable, minors must have permission of legal guardian for participation in the study

Exclusion criteria:

  1. Patients with HS Hurley stage I and III will be excluded from participation
  2. Patients who are pregnant or breast feeding will not be able to take part in the study due to the unknown effects of CO2 laser in pregnant females, as well as risk of lidocaine use during pregnancy and breastfeeding
  3. Any reason the investigator feels the patient should not participate in the study
  4. If a patient misses ≥ 2 consecutive study visits, the patient will be excluded from further participation in this trial
  5. History of allergy to lidocaine or topical anesthetics
  6. Patients with a history of vitiligo as the CO2 laser may cause new spots of depigmentation
  7. Patients with a pacemaker/defibrillator in place
  8. Patients who have previously undergone surgical intervention and recurred in the axilla to be treated
