Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18-65 with chronic atopic dermatitis who have not responded adequately to topical treatments.

Probably not a fit

Patients with mild atopic dermatitis or those who have not been diagnosed with the condition may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 1 clinical trial evaluates the safety and efficacy of BBT001 through a randomized, blinded, placebo-controlled design. The study is divided into three parts: Part A involves healthy volunteers receiving a single ascending dose, Part B involves healthy volunteers receiving multiple ascending doses, and Part C focuses on adult patients with moderate to severe atopic dermatitis receiving multiple doses. The aim is to assess the drug's effects and safety profile in both healthy individuals and those with the target condition.

Why it matters

Potential benefit: If successful, this study could lead to a new treatment option for patients suffering from moderate to severe atopic dermatitis.

How similar studies have gone: While this approach is not widely tested, similar studies have shown promise in evaluating new treatments for atopic dermatitis.
