About this study

Official title: A Single Center Clinical Trial to Evaluate the Effect of Sclerotherapy on Fistulas and Sinus Tracts in Adult Patients With Hidradenitis Suppurativa

This study evaluates the effect of hypertonic saline 23.4% injection in fistulas or sinus tracts in adult patients with hidradenitis suppurativa.

Read the detailed description

The clinical effect of the hypertonic saline treatment will be evaluated with Physician Assessments at week 2 (t=2), week four (t=4) and week 8 (t=8) and compared with the first visit (baseline) (t=0). If necessary, subjects will be eligible to receive another hypertonic saline injected in week 2 and/or week 4, with a maximum of three injections. Simultaneously improvement will be assessed by ultrasound if possible, using the Philips Lumify Ultrasound Device, and by patients using HS Improvement Assessments. Pain and stinging during treatment sessions will be monitored using numeric rating scales (NRS). For monitoring quality of life the DLQI will be used.

Conditions: Hidradenitis Suppurativa
Being tested: 23.4% Hypertonic saline
Medical subject headings: Hidradenitis Suppurativa

What is being measured

The primary outcome is the main question the study is designed to answer.

Secondary outcomes (12)

Numeric Rating Scale for Stinging
Self-reported median stinging intensity during and directly after treatment with Hypertonic saline injections.
Pain with a score of 1 (no stinging at all) to 10 (worst possible stinging).
Measured: Baseline and visit 4 (week 8)
Numeric Rating Scale for Pain
Self-reported median pain intensity during and directly after treatment with Hypertonic saline injections.
Pain with a score of 1 (no pain at all) to 10 (worst possible pain).
Measured: Baseline and visit 4 (week 8)
Length of Fistula
Measuring the length and the lumen of the fistulas using ultrasound if possible.
Measured: Baseline and visit 4 (week 8)
Dermatology Life Quality Index
Number of subjects improving based upon patient-reported outcomes The Dermatology Life Quality Index (DLQI) is a validated general dermatology questionnaire that consists of 10 items that assess subject health-related quality of life (daily activities, personal relationships, symptoms and feelings, leisure, work and school, and treatment)
The scoring of each question is as follows:
Very much scored = 3 points, A lot scored = 2 points, A little scored = 1, Not at all scored = 0 points, Not relevant scored = 0 points, Question 7, 'prevented work or studying' scored = 3 points. The DLQI is calculated by adding the score of each question, resulting in a maximum of 30 (meaning maximum impact on quality of life) and a minimum of 0 (meaning no impact of skin disease on quality of life). The higher the score, the more quality of life is impaired.
0-1 = No effect on patient's life, 2-5 = Small effect, 6-10 = Moderate effect, 11-20 = Very large effect, 21-30 = Extremely large effect.

Limitations and caveats (from the sponsor): Study limitations include 1) small sample size and lack of a control group. 2) the lack of an established scoring system for assessing improvement in individual fistulas. 3) We were unable to determine full fistula dimensions over time with ultrasound. 4) This was a single team of clinical investigators; therefore, treatment efficacy cannot be assessed between study investigators who were not trained by the original investigators.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 23.4% Hypertonic saline in people with Hidradenitis Suppurativa, run by Beth Israel Deaconess Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 28 Mar 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

HS Physician Local Improvement Assessment - PAIN (time frame: Baseline and Visit 4 (week 8)). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02805595.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Mar 2025; AzTrials last refreshed its copy on 8 Nov 2026.
