Study summary

A randomised, adaptive design, double-blind, placebo-controlled, first-in-human, two-part study to investigate the safety, tolerability, PK and preliminary efficacy of multiple topical doses of BEN2293 in patients with mild to moderate AD.

Read the detailed description

This Protocol will be adaptive and designed to enable knowledge gained from the previous cohort to be applied to subsequent cohorts. Changes made will be within the boundaries of the adaptive elements with clear control mechanisms and guidance for staying within these boundaries.

Part A is a randomised, double-blind, placebo-controlled, sequential group study to investigate ascending multiple topical doses of BEN2293 in patients with mild to moderate AD. Patients will participate in only one cohort.

Part B is a randomised, double-blind, placebo-controlled, parallel group study to investigate up to two dose regimens of topical doses of BEN2293 administered for a maximum of 28 days in patients with mild to moderate AD.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Oct 2020 to primary completion in Jan 2023, 26 months.

Of 25 industry-sponsored phase 1/2 interventional studies under Dermatitis, Atopic, half reached primary completion within 22 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 38. This study's 26 months is above that.

Counting every sponsor, half of 29 studies reached it within 22 months; a quarter within 8 and three quarters within 38.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 18, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
