Randomized Double Blind Placebo Controlled Pilot Study on Botulinum Toxin B as Treatment for Hidradenitis Suppurativa

Randomized double blind placebo controlled pilot study/proof of concept-study to see if intradermal injection with Botulinum toxin B is an effective treatment of Hidradenitis suppurativa

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Twenty patients with hidradenitis suppurativa will be enrolled and randomised to treatment with either botulinum toxin B or placebo (saline) in affected areas.

Intervention and recording of data will be performed every three months. After three months, all patients will receive active substance. After six months, randomization will revealed. Patients with clinical improvement will be given the opportunity to continue treatment for additional six months.

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

  • ADULT
  • OLDER_ADULT

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients with active hidradenitis in the stage I-III according to Hurleys classification. Patients are referred to a dermatology out-patient clinic or patients already in an established treatment program, where there is indication for new or different treatment, or surgical intervention. Patients must have typical affection of the disease of either axillae, groins, and/or perigenital/perianal area

Exclusion Criteria:

  • Patients in need of emergency medical or surgical treatment of hidradenitis will be excluded until the disease is in a quiet, controlled phase.

Pregnant or lactating, as well as patients with neurological disease such as myasthenia gravis or motor neuron disease.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Patient reported improvement after invention with Botulinum toxin B
Time Frame: End point analysis 6 months
Outcome measured by Dermatological Life Quality Index (DLQI)-scores
End point analysis 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Identification of clinical subgroups with best response to intervention as assessed by clinically scored measures
Time Frame: Interim analysis after 6 weeks- 3 months. End point analysis 6 months and sub group analysis 12 months
Registration and analysis on investigator scored measures assessed by Hidradenitis suppurativa score (HiSCR) in relation to clinical phenotypes (location, Hurley stage)
Interim analysis after 6 weeks- 3 months. End point analysis 6 months and sub group analysis 12 months
Identify if covariates such as age, disease duration, smoking state, BMI and sweating influence patient reported improvement
Time Frame: Interim analysis after 6 weeks- 3 months. End point analysis 6 months and sub group analysis 12 months
Covariate analysis on patient recorded DLQI in relation to pre-registered variables

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
