Every day feels uncertain when you live with hidradenitis suppurativa (HS). Painful lumps can disrupt almost any activity, leaving you with relentless discomfort. We're currently evaluating a study medicine that is a pill you swallow daily to see if it can help get better control of HS symptoms. If you are interested in exploring options, we invite you to learn about our clinical trial.

Our clinical trial is looking for people who are living with HS to see if a study medicine that is a pill you swallow daily can help better control symptoms. If you choose to take part in this clinical trial, you’ll receive care from a team of dedicated specialists that could help us continue to make progress for HS research.

Who may participate

This clinical trial may be an option for adults who have moderate to severe hidradenitis suppurativa (HS) with lumps in at least 2 different areas of the body and who still have HS symptoms after taking at least 4 weeks of oral antibiotics. 

There will be other requirements that the trial team will discuss with you.

 Joining a clinical trial is an important and personal decision. We thank you for considering taking part as an option that may be right for you.

About hidradenitis suppurativa (HS)

HS is a skin condition that causes small, painful lumps to form beneath the skin. The lumps usually appear in areas where skin rubs together such as the armpits, groin, and under the breasts. Despite its appearance, HS is not contagious.
