TMB-001 Ointment for Ichthyosis
(ASCEND Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new ointment, TMB-001, for individuals with ichthyosis, a condition that causes dry, scaly skin. Researchers aim to determine if this ointment is safe and effective for treating two types of ichthyosis: RXLI and ARCI. Participants will apply the ointment daily or twice daily over several weeks to assess its effectiveness compared to a placebo. Suitable candidates have ichthyosis affecting 10-90% of their skin and a documented history of moderate to severe disease. As a Phase 3 trial, this is the final step before FDA approval, offering participants a chance to contribute to the potential availability of a new treatment.
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 there any evidence suggesting that TMB-001 ointment is likely to be safe for humans?
Research has shown that TMB-001 0.05% ointment was well-tolerated in past studies. One study found no serious safety concerns or signs of harmful absorption levels in the body. This indicates the treatment did not cause worrying side effects. Earlier trials also demonstrated positive results without major safety issues, suggesting that TMB-001 is generally safe for individuals with congenital ichthyosis, a genetic skin disorder causing dry, scaly skin. While ongoing studies will provide more information, current evidence suggests that TMB-001 is a safe option.12345
Why do researchers think this study treatment might be promising for ichthyosis?
Unlike the standard treatments for ichthyosis, which often involve moisturizing creams and systemic retinoids, TMB-001 ointment offers a targeted approach with its active ingredient: isotretinoin. This topical formulation allows for direct application to the skin, potentially reducing systemic side effects typically associated with oral retinoids. Researchers are excited because TMB-001's novel delivery method could provide effective relief with fewer side effects, while its flexible dosing schedule aims to optimize patient convenience and adherence. This innovative approach could significantly enhance quality of life for individuals with ichthyosis.
What evidence suggests that TMB-001 ointment might be an effective treatment for ichthyosis?
Research has shown that TMB-001 0.05% ointment may help treat congenital ichthyosis (CI). In earlier studies, patients using TMB-001 experienced much smoother skin with fewer cracks. The treatment appears safe, as past studies found no major changes in lab tests. In this trial, participants will receive TMB-001 0.05% ointment, which could be a promising alternative to oral retinoids, commonly used pills for skin conditions like CI.35678
Are You a Good Fit for This Trial?
This trial is for males and females aged 6 and older with a clinical diagnosis of Congenital Ichthyosis (CI), specifically RXLI or ARCI subtypes, confirmed by genetics. Participants must have significant skin scaling and be in good health. Women who can bear children must use two forms of birth control. Those pregnant, lactating, or planning pregnancy; using certain treatments like UV therapy or systemic immunosuppressants; with untreated infections; drug/alcohol abuse history; on other trials; failed retinoid therapies; liver/kidney issues are excluded.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- TMB-001
Trial Overview
The study tests TMB-001 ointment's safety and effectiveness against CI compared to a placebo (vehicle). It has three phases over 24 weeks: an initial induction period with once-daily treatment, increased to twice daily during the main treatment phase, followed by maintenance where dosing frequency may vary based on response. An optional arm studies systemic exposure in those with extensive affected skin.
