Study summary

The purpose of this study is to find out how well tilrekimig works, how safe it is, and how it affects the body in adults and adolescents with moderate to severe atopic dermatitis (eczema). Eczema is a condition which can cause dryness, itching, and redness of your skin.

The study is seeking participants who:

  • Are aged 12 years or older.
  • Were confirmed to have atopic dermatitis (AD) at least 12 months ago.
  • Are not having an effective treatment result from medicines that are applied on skin for AD.
  • Are considered by their doctors to have moderate to severe AD.

The study treatment period will be 52 weeks. During the 24-week initial treatment period, participants will be randomized to one of three study treatments - tilrekimig, dupilumab, or placebo. Placebo does not have any medicine in it but looks just like the medicine being studied. These treatments will be randomized based on a 2:2:1 ratio. This means out of 1375 participants, about 550 participants will receive tilrekimig, 550 will receive dupilumab, and 275 will receive placebo. This will be followed by a 28-week maintenance period. The last dose of study treatment will be administered at week 48.

Some participants will join the long-term extension (LTE) study C4531008 at week 52. A long-term extension study is an additional study that some participants may be able to join after completing the study if they are interested and meet eligibility requirements. It allows researchers to continue collecting information about how well the study medicine works. It also helps them assess how safe it is when used for a longer period of time. Participants who do not join this study will enter a 12-week safety follow-up period. This period ends 16 weeks after their last dose of study treatment.

Eligibility criteria

Key Inclusion Criteria

  • You are [12] years of age or older
  • You have had moderate-to-severe eczema for at least 1 year
  • Topical medicines for eczema have not worked well for you

Key Exclusion Criteria

  • Disease
  • Significant Infection History or Active Infection
  • Known or Suspected Immunodeficiency/
  • Significant psychiatric illness or suicidality
  • Clinically significant hepatic, renal, or hematologic abnormalities
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

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.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

ElapsedEstimatedEstimated, not yet reachedDate before it movedWhere the date was before it movedSimilar 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

Started Aug 2026 (actual). Primary completion is estimated for Sep 2028, 24 months after the start.

Of 149 industry-sponsored phase 3 interventional studies under Dermatitis, Atopic, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 28. This study's planned 24 months is above that.

Counting every sponsor, half of 156 studies reached it within 18 months; a quarter within 13 and three quarters within 28.

Primary completion moved once since we started tracking on Sep 25, 2026: Aug 2028 → Sep 2028, on Oct 6, 2026.

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.
