Summary

This study compares two oral drugs, apremilast and acitretin, to see which works better for moderate-to-severe hidradenitis suppurativa, a painful skin condition. About 70 adults take one of the two pills twice daily for 12 weeks. The main goal is to measure how much the disease severity improves.

What this could lead to

What could go wrong
This is a small, 12-week trial, so results may not apply to all patients or predict long-term outcomes. Both drugs have potential side effects.
