Background: Amlitelimab, a fully human, nondepleting, anti-OX40 ligand monoclonal antibody, demonstrated reductions in lesional and pruritic endpoints in adults with moderate-to-severe atopic dermatitis (AD) in phase 2a and 2b trials.
Objectives: Here, we examined the effect and durability of amlitelimab on clinical outcome assessments (COAs) in the randomized STREAM-AD phase 2b trial.
Methods: Adults with moderate-to-severe AD with prior inadequate response to or inadvisability of topical medications received subcutaneous amlitelimab (250 mg with 500-mg loading dose, 250 mg, 125 mg or 62.

Atopic dermatitis (AD) is a chronic inflammatory skin disorder that significantly impacts patients' quality of life. Novel biological agents targeting the OX40 pathway have shown promise in refractory cases. We aimed to systematically evaluate the efficacy and safety of anti-OX40 therapies (amlitelimab, rocatinlimab, and telazorlimab) in moderate-to-severe AD.

Background: Amlitelimab, a fully human nondepleting mAb targeting OX40 ligand on antigen-presenting cells, could prevent T-cell-driven inflammation seen in atopic dermatitis (AD).
Objective: This trial evaluated the efficacy and safety of amlitelimab in adults with AD.
Methods: In this 2-part, phase 2b, randomized, double-blinded placebo-controlled trial (ClinicalTrials.

Background: Atopic dermatitis (AD) is an inflammatory skin disease with significant unmet need. Blockade of the OX40-OX40 ligand (OX40L) costimulation pathway by targeting OX40L on antigen-presenting cells (APCs) with a fully human noncytotoxic, nondepleting anti-OX40L monoclonal antibody (amlitelimab; SAR445229; KY1005) is a novel way to modulate persistent inflammation.
Objectives: To assess the safety and efficacy of amlitelimab over 16 weeks in adults with AD in a phase IIa double-blind placebo-controlled study.
