Optimization of Cyclosporin in Atopic Dermatitis Through Multiomic Predictive Models of Treatment Response

Phase 4
Recruiting
Conditions
Atopic Dermatitis
Interventions
Other: Follow-up of Cyclospoin treatment already started
Registration Number
NCT05692843
Lead Sponsor
Instituto de Investigación Hospital Universitario La Paz
Brief Summary

This is a low-intervention phase IV trial. The main objective is to optimize the treatment of patients with moderate-severe atopic dermatitis who require systemic treatment.

Detailed Description

Primary outcome is the percentage of patients with primary non- response to treatment with cyclosporin. 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 of 100 patients with moderate-severe atopic dermatitis will be recruited. The study is divided into two cohorts. All patients diagnosed with moderate-severe atopic dermatitis who are going to receive treatment with cyclosporin in the Dermatology Service of La Paz University Hospital and associated Specialty Centers are selected in cohort 1. Patients will receive the starting dose used in routine clinical practice. All patients diagnosed with moderate-severe atopic dermatitis who are receiving or have received cyclosporin therapy in the Dermatology Service of La Paz University Hospital and associated Specialty Centers are selected in cohort 2.

Inclusion Criteria

Cohort 1:

  1. Subjects diagnosed with moderate-severe atopic dermatitis who are going to receive treatment with cyclosporine.
  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 receiving or have received in the past treatment with cyclosporine.
  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
  1. Subjects participating in a clinical trial in the last three months.
  2. Any condition or situation precluding or interfering the compliance with the protocol.
  3. Women of childbearing potential must have a negative urine pregnancy test at Screening and Day 0.
  4. Women of childbearing potential must commit not to become pregnant. They must be willing to use highly effective contraceptive methods or have practiced sexual abstinence during the study. Highly effective contraceptive methods include oral, intravaginal, or transdermal combined (oestrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation; oral, injectable, or implantable progestogen-only hormonal contraception associated with inhibition of ovulation; intrauterine device; intrauterine hormone-releasing system; bilateral tubal occlusion; vasectomised partner and sexual abstinence.

Arm && Interventions
GroupInterventionDescription
Receiving or received cyclosporinFollow-up of Cyclospoin treatment already startedIf the patient is receiving cyclosporine therapy, a blood sample for pharmacogenetic analysis will be obtained at screening; also, at discretion of the treating physician, biological samples will be obtained (blood and urine) in this visit and in the follow-up visits to assess biochemical and kinetic variables. Clinical data (scales) will be collected from clinical records from treatment start until study inclusion and prospectively after study inclusion. If the patient received cyclosporine previously but is no longer under CsA therapy, a blood sample will be extracted at screening for pharmacogenetic analysis. Clinical data (scales) will be collected from clinical records.
Start of Cyclosporin treatmentCyclosporin APatients will receive the starting dose used in routine clinical practice (maximum dose of 3 mg/kg/day is standard practice in our center). Once the patient is included in the clinical trial their therapeutic management will be carried out according to usual clinical practice, but additional procedures will be performed: 1. The frequency of follow-up visits will be increased in order to collect data related to clinical efficacy, safety and quality of life; 2. Biological samples will be obtained (blood and urine) for biochemical, kinetic, pharmacogenetic and immunological biomarker analysis to identify variables associated to CsA treatment.

NameTimeMethod
Mean percentage of change in EASI scoreWeek 16

Mean percentage of change in EASI score from baseline to week 16

Change of BSAweek 16

Change of BSA (Body surface area) involment

Time to treatment failure after week 16Week 24, week 32, week 40, week 48.

Time to treatment failure with cyclosporine defined as EASI ≤ 50 during follow-up after week 16.

Percentage of change in SCORADWeek 16

The Scoring of Atopic Dermatitis (SCORAD) is the score of the severity of atopic dermatitis. It includes the evaluation of the affected areas. The intensity of the lesions and the subjective symptoms of the patient. Classifies AD as Mild \>25, Moderate 25-50, and Severe \>50

Percentage of patients having a variation of 4 points in their improvement in DLQIthrough study completion, an average of 1 year

Dermatology Life Quality Index is a validated and widely used 10-item questionnaire with paediatric versions (0-3 and 4-16 years). A variation of 4 points is considered a clinically meaningful endpoint.

Percentage of patients reaching EASI-90through study completion, an average of 1 year

Percentage of patients reaching 90 percentage (EASI-90) improvement from baseline during follow-up

improvement of at least 75% in SCORADthrough study completion, an average of 1 year

Percentage of patients experiencing an improvement of at least 75% in SCORAD from the baseline value

Change of IGAweek 16

Investigator Global Assessment (IGA) is a simple objective measure providing an overall evaluation. It uses a 5-point scale (clear=0; almost clear=1; mild=2; moderate=3; severe=4).

Percentage of patients achieving EASI-75week 6

Fail to achieve EASI-75 (a 75% improvement in EASI score)

Time to IGA score of 0/1through study completion, an average of 1 year

Time to IGA score of 0/1 (clear or almost clear)

Change in NRSweek 16

NRS (Numerical Rating Scale) is a numerical scale that measures the intensity of pruritus, with 10 being the greatest intensity

Change in POEMweek 16

The Patient-Oriented Eczema Measure (POEM) is a validated tool in which the patient self-assesses how many days they experienced seven distinct items (itch, sleep disturbance, bleeding, weeping/oozing, cracking, flaking, dryness of the skin) during a period of 1 week. The maximum score is 28 points.

Change in DLQIweek 16

Dermatology Life Quality Index is a validated and widely used 10-item questionnaire with paediatric versions (0-3 and 4-16 years). A variation of 4 points is considered a clinically meaningful endpoint.

Rate of adverse events associated to CsA treatmentthrough study completion, an average of 1 year

Any untoward medical occurrence in a patient or clinical trial participant, which does not necessarily have a causal relationship with the research procedures or the investigational medicinal product
