E.3 | Principal inclusion criteria |
- Adult male or female participants with chronic atopic dermatitis, according to the American Academy of Dermatology Consensus Criteria (Eichenfield et al 2014), aged 18 to 65 years, present for at least 1 year before screening. - Moderate to severe AD defined as: --IGA score of ≥ 3 (on a scale of 0 to 4, in which 3 is moderate and 4 is severe) at Baseline (or Screening if Baseline is omitted) --EASI score of ≥ 12 at Baseline (or Screening if Baseline is omitted) --Pruritus (NRS) of at least ≥ 3 at Baseline (or Screening if Baseline is omittied) - Participants who are candidates for a systemic therapy, defined as e.g. inadequate response to treatment with topical medications, or from whom topical treatments are otherwise medically inadvisable (e.g., because of important side effects or safety risks, patients with large affected body surface areas), as assessed by the investigator - Participants must have a body mass index (BMI) at screening within the range of 18 to ≤35 kg/m2. Other criteria may apply as per protocol, |
-Participantes adultos de 18 a 65 años de ambos sexos con DA crónica, según los criterios de consenso de la Academia Estadounidense de Dermatología (AAD) (Eichenfield et al., 2014), que haya estado presente durante al menos un año antes de la selección. - La DA de moderada a grave se define como: - Puntuación de la evaluación global del investigador (IGA) >/=3 (en una escala de 0 a 4, en la que 3 equivale a moderado y 4 a grave) en la basal (o en la selección si se omite la basal). - Puntuación del Eczema Area and Severity Index (EASI) >/=12 en la basal (o en la selección si se omite la basal). - Escala numérica de prurito con un valor de al menos >/=3 en la basal (o en la selección si se omite la basal). - Participantes que sean candidatos para un tratamiento sistémico, definido como p. ej., una respuesta inadecuada al tratamiento con medicamentos tópicos, o para quienes los tratamientos tópicos no sean médicamente aconsejables (p. ej., debido a efectos secundarios importantes o riesgos de seguridad, pacientes con grandes áreas de superficie corporal afectadas), según lo evalúe el investigador. - Los participantes deben tener un índice de masa corporal (IMC) en la selección de entre 18 y </=35 kg/m2. IMC = peso corporal (kg)/[estatura (m)]2. |
|
E.4 | Principal exclusion criteria |
- Any skin disease that, in the opinion of the investigator, would confound the diagnosis or evaluation of AD disease activity (e.g., Netherton Syndrome, or other ichthyoses, cutaneous T-Cell Lymphoma, extensive contact dermatitis, chronic actinic dermatitis and other forms of eczema, such as seborrheic and microbial eczema). - Participants taking prohibited medication with their wash out period - Use of other investigational drugs at the time of enrollment, or within 5 half-lives of enrollment, or until the expected PD effect has returned to baseline, whichever is longer; or longer if required by local regulations. - Any active, recent or recurrent systemic or localized infection at screening or prior to first treatment which in the opinion of the investigator immunocompromises the participant and/or places the participant at unacceptable risk for immunomodulatory therapy. - Any other current or past clinical significant medical condition, including psychiatric condition, which in the investigator's opinion may interfere with safety of participants, study objectives or adherence to the protocol. - Participants with confirmed abnormal absolute neutrophil count (ANC) of <1.5 x 109/L or with thrombocytopenia of < 75.0 x 109/L at screening and baseline (unless baseline visit is omitted) - History of malignancy of any organ system (other than localized basal cell carcinoma of the skin), treated or untreated, within the past 5 years, regardless of whether there is evidence of local recurrence or metastases - History of hypersensitivity to any component of the study drug product, or to drugs of similar chemical classes (i.e., IgG-1 related biologic agents) - History of severe or serious allergy or hypersensitivity reactions, such as anaphylactic shock, asthma, or uncontrolled urticaria. - Women of child-bearing potential (WoCBP), defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception while taking study treatment and for 6 months after last dose. |
- Cualquier enfermedad cutánea que, a juicio del investigador, confundiría el diagnóstico o evaluación de la actividad de la DA (p.ej., síndrome de Netherton u otros trastornos ictiósicos, linfoma cutáneo de células T, dermatitis de contacto extensa, dermatitis actínica crónica y otras formas de eczema, como eczema seborreico o eczema microbiano.) - Participantes que tomen medicación prohibida que no completen el periodo de lavado como se especifica en la Tabla 6-2. - Uso de otros fármacos en investigación en el momento del reclutamiento o durante las 5 vidas medias anteriores al reclutamiento o hasta que el efecto PD previsto vuelva a los valores basales, aquel periodo que sea más largo; o durante más tiempo si así lo exige la normativa local. - Cualquier infección sistémica o localizada activa, reciente o recurrente en la selección o antes del primer tratamiento que, a juicio del investigador, inmunodeprima al participante y/o le coloque en un riesgo inaceptable para la terapia inmunomoduladora. - Cualquier otra enfermedad actual o pasada de interés clínico, incluyendo una enfermedad psiquiátrica, que, a juicio del investigador, pueda interferir en la seguridad de los participantes, los objetivos del estudio o el cumplimiento del protocolo. - Participantes con recuento absoluto de neutrófilos (RAN) anormal confirmado <1,5 x 109/l o con trombocitopenia <75,0 x 109/l en la selección y la basal (a menos que se omita la visita basal). - Antecedentes de tumor maligno en cualquier sistema orgánico (salvo carcinoma cutáneo de células basales localizado), tratado o no tratado, durante los últimos 5 años, independientemente de que existan o no pruebas de recurrencia local o metástasis. - Antecedentes de hipersensibilidad a alguno de los componentes del fármaco del estudio o a fármacos de clases químicas similares (es decir, agentes biológicos relacionados con IgG-1). - Antecedentes de reacciones alérgicas o de hipersensibilidad intensas o graves, como shock anafiláctico, asma o urticaria incontrolada. - Mujeres con posibilidad de quedarse embarazadas, definidas como toda mujer fisiológicamente capaz de quedarse embarazada, salvo que esté utilizando métodos anticonceptivos altamente eficaces durante el tratamiento del estudio y durante los 6 meses posteriores a la última dosis. |
