New ointment shows promise for rare skin scaling disease
NCT ID NCT04154293
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two strengths of a topical isotretinoin ointment (TMB-001) in 34 people aged 9 and older with congenital ichthyosis, a rare genetic skin condition causing severe scaling. The main goal was to see if the ointment could reduce scaling by at least 50% compared to a placebo ointment. The trial is now complete, and results will show whether this treatment is safe and effective.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Topical isotretinoin (TMB-001) ointment
- What this could lead to
- If successful, this could provide a new topical treatment to reduce severe scaling and improve skin appearance in people with congenital ichthyosis.
- What could go wrong
- This is a small Phase 2 trial with only 34 participants, so results may not apply to everyone. Topical isotretinoin can cause skin irritation, and the treatment may not work for all subtypes.
