Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 1 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2019-10-09

Brief Summary

Apremilast mediates its clinical effect through the cAMP-PKA-NFkappaB pathway which results in a clinical picture changes to a decrease of all signs of inflammation.

Due to the NFkappaB mediated chronical inflammation in the pathogenesis of acne conglobata, a treatment with Apremilast seems to be an effective option.

In this study, treatment with Apremilast (Otezla®) will be performed in patients with acne conglobata to observe its preliminary efficacy and safety in an open label, single-centre proof of concept study design.

Detailed Description

Treatment options for acne conglobata are limited and those which are effective can only be used in short term such as systemic steroids, antibiotics or retinoids due to their association to side effects or potentially teratogenetic effects.

Apremilast, a specific inhibitor for PDE-4, mediates its clinical effect through the cAMP-PKA-NFkappaB pathway which results in a decrease of pro-inflammatory and increase of anti-inflammatory cytokines in several types of leukocytes. The clinical picture changes to a decrease of all signs of inflammation.

Due to the NFkappaB mediated chronical inflammation in the pathogenesis of acne conglobata, a treatment with Apremilast seems to be an effective option.

In this study, treatment with Apremilast (Otezla®) will be performed in patients with acne conglobata to observe its preliminary efficacy and safety in an open label, single-centre proof of concept study design.

• History of clinically significant infection within the last 4 weeks before screening, which, in the opinion of the treating physician, may compromise the safety of the patient

• Severe kidney insufficiency (glomerular filtration rate (GFR) < 30 ml/min)
• Any severe disease, which, in the opinion of the treating physician, may interfere or worsen the acne conglobata or could become a safety problem for patients
• History of or current Hepatitis-B, Hepatitis-C or HIV infection
• Any active medication which suppresses the immune system, including disease modifying anti-rheumatic drugs (DMARDs) and biologicals
• Current participation in another investigational clinical trial or participation within 30 days prior to screening
