The atopic dermatitis trial landscape in 2026
Atopic dermatitis is one of the most competitive therapeutic areas in immunology-driven drug development. Dupilumab's commercial success — blockbuster revenues exceeding $10B annually — has attracted every major immunology company to the space. The result is a dense, complex trial landscape with overlapping mechanisms, pediatric extensions, and aggressive head-to-head programs.
For dermatology pharma and biotech teams, keeping up with new trial registrations across IL-4/IL-13, JAK inhibitors, OX40, TSLP, IL-31, and emerging mechanisms requires systematic monitoring. DataLookout automates this work.

IL-4/IL-13 dual inhibition and selective targeting
Following dupilumab (IL-4Rα), the second wave targets related cytokines with higher selectivity or improved dosing profiles. Programs include:
- Subcutaneous anti-IL-13 antibodies with monthly or less frequent dosing
- Next-generation IL-4Rα antibodies with extended half-life and self-injection devices
- Tralokinumab (IL-13 selective) follow-on combination studies
- Bispecifics combining IL-4/IL-13 with TSLP or OX40L blockade
JAK inhibitors: oral and topical
Three JAK inhibitors are approved for moderate-to-severe AD (baricitinib, upadacitinib, abrocitinib). New trial activity focuses on:
- JAK1-selective inhibitors with improved tolerability profiles
- Topical JAK inhibitors for mild-to-moderate disease (ruxolitinib cream approved; new entrants in development)
- Combination of oral JAK inhibitors with dupilumab for refractory patients
- Long-term safety extensions and real-world evidence studies
OX40 and OX40L: memory T cell targeting
OX40 pathway blockade addresses AD at the memory T cell level, potentially offering longer disease modification. Rocatinlimab (anti-OX40) is in late-stage development; amlitelimab (anti-OX40L) has shown Phase 3 data. New trials are exploring:
- Combination with IL-4/IL-13 inhibitors for refractory patients
- OX40 in pediatric populations and prevention studies
- Long-term maintenance and treatment-free remission protocols
TSLP and IL-33 upstream inhibition
Tezepelumab (anti-TSLP) showed modest activity in AD; next-generation TSLP and IL-33 programs are testing higher dose levels, pediatric populations, and combination strategies. Itepekimab (anti-IL-33) has an active AD program.
Novel topical and non-systemic approaches
For mild-to-moderate AD, the development pipeline has expanded beyond TCS/TCI to include:
- PDE4 inhibitors (crisaborole follow-ons with improved potency and tolerability)
- Aryl hydrocarbon receptor (AhR) modulators: tapinarof approved; next-generation compounds in trials
- IL-31 antagonists targeting itch specifically (nemolizumab Phase 3)
- Microbiome-targeted approaches (Staphylococcus aureus decolonization strategies)
Who monitors atopic dermatitis clinical trials?
