What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a skin ointment called TMB-001 for people with a chronic skin condition called Congenital Ichthyosis. The ointment helps by reducing excess skin production and promoting shedding. The study aims to see if TMB-001 is safe and effective for these patients.

Will I have to stop taking my current medications?

The trial requires that you stop using certain topical treatments and therapies in the treatment areas before starting the study. Specifically, you must not use topical prescription or over-the-counter therapies (except emollients, keratolytics, and topical steroids) within 2 weeks before the study begins, and you must avoid keratolytics or topical corticosteroids within 5 days before starting. Additionally, you should not have used oral isotretinoin in the past 12 months or ultraviolet treatment within 4 weeks before the study.

Is TMB-001 ointment safe for humans?

In a study, TMB-001 ointment was used for 12 weeks in people with congenital ichthyosis and did not cause any significant changes in lab tests, suggesting it is generally safe.12345

What data supports the effectiveness of the drug TMB-001 Ointment for Ichthyosis?

The Phase 2b CONTROL study suggests that TMB-001, a topical form of isotretinoin, did not cause significant lab changes in patients with congenital ichthyosis, indicating it may be a safer alternative to oral retinoids, which are known to be effective but can have serious side effects.12367
