Optimization of Atopic Dermatitis Treatment That Requires Second-line Systemic Therapy Through Predictive Models

Overview

This is a low-intervention phase IV trial. The main objective is to optimize the treatment of patients with moderate-severe atopic dermatitis that require systemic treatment after failure, intolerance or contraindication to cyclosporine.

Description

Primary outcome is the percentage of patients with primary non-response to second-line treatment. Defined as fail to achieve EASI-75 (a 75% improvement in EASI score) at week 16 of follow-up. A 12-month recruitment period is planned and about 150 patients with moderate-severe atopic dermatitis will be recruited. The study is divided into two cohorts. All patients diagnosed with moderate to severe atopic dermatitis who are going to receive second-line systemic treatment at the Dermatology Department of La Paz University Hospital are selected in cohort 1. Patients will receive the starting dose used in routine clinical practice. All patients diagnosed with moderate to severe atopic dermatitis who are receiving second-line systemic treatment at the Dermatology Department of La Paz University Hospital will be selected in cohort 2.

Eligibility

Inclusion Criteria:

Cohort 1:

2. Participants must be willing and able to provide written informed consent prior the initiation of any study procedures.
3. For children, parent/legal guardian must provide written informed consent. If age >11 years old, the minor must give assent.
4. Participant is willing and able to adhere to the procedures specified in this protocol.

Cohort 2:

1. Subjects diagnosed with moderate-severe atopic dermatitis who are already receiving authorized second-line systemic therapy at the time of selection.
2. Participants must be willing and able to provide written informed consent prior the initiation of any study procedures.
3. For children, parent/legal guardian must provide written informed consent. If age >11 years old, the minor must give assent.
4. Participant is willing and able to adhere to the procedures specified in this protocol.

Exclusion Criteria:
