July 23, 2018 updated by: M.B.A. van Doorn

Short-term Safety, Efficacy and Mode of Action of Apremilast in Moderate Suppurative Hidradenitis: A Randomised Double-blind Placebo Controlled Trial

Study design: A double-blind randomised placebo-controlled trial

Intervention: Randomized placebo controlled treatment of 20 HS patients of which fifteen patients will be randomized to apremilast and five patients to placebo. The total duration of the treatment period per subject is 16 weeks.

Primary objectives: To evaluate the expression profile of inflammatory cytokines in HS lesional skin at week four (t=4) and week sixteen (t=16):

  • of patients receiving apremilast compared to placebo;
  • within both groups relative to baseline (t=0).

Secondary objectives:

  • To prospectively evaluate the clinical efficacy of apremilast.
  • To assess the effect of apremilast on patient reported outcomes measures.
  • To assess the short-term safety and tolerability of apremilast in patients with hidradenitis suppurativa.

Detailed Description

Rationale:

Hidradenitis suppurativa (HS) is a chronic, inflammatory, recurrent, debilitating skin disease. It is characterized by painful, deep-seated, inflamed boils in the inverse areas of the body, most commonly the axillae, inguinal and anogenital regions.

Systemic therapy with immunosuppressive agents (systemic corticosteroids, dapsone, cyclosporin) has been investigated in the past decades and has shown limited efficacy. The use of the selective immunosuppressant apremilast has not yet been evaluated in HS. The investigators hypothesize a beneficial effect of apremilast in HS patients, similar to the efficacy of apremilast in psoriasis patients. Namely, it has been shown that the immune dysregulation in the pathogenesis of HS shows many similarities with that of psoriasis. Moreover, the TNF-α blocker adalimumab was registered for HS after approval for the treatment in patients with psoriasis.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
Change of expression levels of inflammatory cytokine mRNA in HS lesional skin.
Time Frame: t=16 weeks

measurement by ELISA
t=16 weeks

Secondary Outcome Measures
