NCT05642208

Brief Summary

The goal of this clinical trial is to compare a step-down strategy of spacing dupilumab injections with a standard maintenance treatment in adolescents and adults with controlled Atopic dermatitis (AD) for at least six months. The impact of dosage reduction strategies will be assessed with an innovative primary endpoint: the area under the curve of the weekly ADCT assessment.

Outcome Measures

Primary Outcomes (1)

  • Area under the curve of Atopic Dermatitis Control Tool (ADCT)

    to demonstrate the non-inferiority of a step down dosage strategy of dupilumab as compared with maintenance of initial treatment, on long-term control of the disease severity at one year in adolescents and adults patients with controlled AD.The primary endpoint is the Area under the curve of Atopic Dermatitis Control Tool (ADCT) score achieved by the patient every week during one year. As the ADCT score refers to the last 7 days, a weekly assessment is the most accurate to detect all variations in disease severity intensity.

    over 12 months

Secondary Outcomes (6)

  • Mean difference in EASI score

    every 4 months over 12 months

  • Mean difference in Investigator global assessment

    every 4 months over 12 months

  • Mean difference in Itch numerical rating scale

    every 4 months over 12 months

  • The patient quality of life will be assessed with the DLQI (Dermatology Life Quality Index) measured at M4, M8, M12 or with the CDLQI (Children Dermatology Life Quality Index) for children under 16. Mean difference in DLQI (CDLQI for children <16)

    every 4 months over 12 months

  • cost-utility analysis performed from a health care system perspective

    over 12 months

  • +1 more secondary outcomes

Study Arms (2)

Experimental Group

EXPERIMENTAL

Injections will be spaced as : * Every 3 weeks between M0 and M4, * Every 4 weeks between M4 and M8 (if ADCT\<7 and IGA ≤ 2, AD assessed as controlled by the investigator and stable amount of local treatment used), * Then every 5 weeks until the end of the clinical trial (M12) (if ADCT\<7 and IGA ≤ 2, AD assessed as controlled by the investigator and stable amount of local treatment used). In case of ADCT≥7 or IGA \> 2 or disease assessed as uncontrolled by the investigator, the injection interval treatment will be step up to the previous interval. The treatment is administered subcutaneously and can be delivered in pen or syringe for subcutaneous injection. The dosage is usually : * 300 mg per injection for adults and adolescents (12-17 years) weighing more than 60 kg * 200 mg per injection for adolescents (12-17 years) weighing less than 60 kg.

Drug: Dupilumab step-down

Control group

NO INTERVENTION

in this group the interval between injections is maintained every 2 weeks (14 days) throughout the clinical trial. The treatment is administered subcutaneously and can be delivered in pen or syringe for subcutaneous injection. Treatment will be prescribed in the control group according to the marketing authorization dosage (see paragraph 5.1). The dosage is usually : * 300 mg every 14 days for adults and adolescents (12-17 years) weighing more than 60 kg * 200 mg every 14 days for adolescents (12-17 years) weighing less than 60 kg.
