Penn State 'Teledermatology' Survey

5 minute survey regarding 'teledermatology' a service where you visit your derm via email or phone if you can't make it to clinic.

Complement C5a Receptors in Hidradenitis Suppurativa

To study the role of C5a in Hidradenitis Suppurativa (HS). Complement C5a is a major chemotactic factor that stimulates neutrophil infiltration.

Study of Efficacy & Safety of Investigational Treatments in Patients With Moderate to

Severe HS



The main purpose of this study is to assess preliminary efficacy and safety of CFZ533 and LYS006 in patients with moderate to severe hidradenitis suppurativa and to determine if CFZ533 and LYS006 have an adequate clinical profile for further clinical development.

Low Dose Radiotherapy for Advanced Hidradenitis Suppurativa (RTHS)



To establish the safety of radiotherapy in the treatment of advanced hidradenitis suppurativa. Patients will receive radiotherapy treatment over one week and then will be followed for the next three months.

Effect of Sclerotherapy on Fistulas and Sinus Tracts in HS



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

Molecular Biology and Genetics of Hidradenitis Suppurativa


Analysis of Gene expression and microbiome profiling in hidradenitis suppurativa to identify immunological biomarkers of disease activity.

National Registry For Patients With HS



5 year study for adult and pediatric HS patients.  Various States.  Click below for info.






To evaluate the safety and efficacy of 2 dose levels of risankizumab in adult participants with moderate to severe Hidradenitis Suppurativa (HS).


Scheduled to conclude February 2020


The primary objective of this study is to demonstrate equivalence of the pharmacokinetic (PK) profile of MSB11022 administered by either an auto-injector (AI) or a pre-filled syringe (PFS) as single subcutaneous (s.c.) injection of 40 mg.

UK Clinical Trials

HS Written Action Plan Trial (HSWAP)

The goal is to gain a better understanding of the condition and how to manage the condition on a daily basis compared to a routine verbal consultation.

Wound Care Trial in Ireland

Open to anyone in Ireland. 


Volunteers are needed for a wound care clinical trial. HS warriors are needed to participate in this trial for HS wound dressing of the armpits.

Treatment of Hidradenitis Suppurativa With Eth 755nm Alexandrite Laser



Patients with bilateral hidradenitis in the axilla, groin and/or inframammary will be treated on one side with the Alexandrite hair removal laser. The other side will serve as the control.

Wound Etiology and Healing Study (WE-HEAL)




The purpose of the WE-HEAL Study is to help researchers use human tissue samples and health records to study the reasons why some patients heal quickly and some have problems healing wounds. All patients seen with an open wound or hidradenitis suppurativa are invited to participate. Information from this research may help to understand how to prevent and treat certain diseases.

Impact of Hidradenitis Suppurativa on Quality of Life Functions



The goal of this study is to get a better understanding of the impact of Hidradenitis Suppurativa (HS) on the quality of life of patients with this condition.  Study participation will last for 1 day, with potential for follow-up in the future.

Epidermal Barrier Function With Anti-Oxidant Defense

Mechanisms in Skin Conditions



Investigators will sample the skin and blood of patients with chronic skin conditions (including but not limited to atopic dermatitis (AD), contact dermatitis, hidradenitis suppurativa (HS), and psoriasis) to study the expression of anti-oxidative enzymes, skin barrier proteins and inflammatory molecules.

ISMIC (Target-Derm)



5 year study for adult and pediatric HS patients.  Various States.  Click below for info.





Some locations have started to recruit and others will be starting soon. Click below to learn more.


It is a receptor inhibitor acting like a biologic and an immunosuppressant and was developed for both auto-inflammatory and autoimmune illnesses. They also have expectations that Avacopan can be used as an alternative to corticosteroids. It inhibits the complement C5a receptor, or C5aR, for inflammatory diseases. Avacopan blocks the activity of complement C5a, a component of the complement system and the for C5aR.
