    E.3Principal inclusion criteria
    A patient must meet the following criteria to be eligible for inclusion in the study:
    1. Underwent study treatment in a prior clinical trial of dupilumab for AD and met one of the following:
    a. Adequately completed the assessments required for both the treatment and follow-up periods of the parent studies (except studies listed in b) as defined in the parent protocols; specifically, patients must complete the primary endpoint visit and at least
    50% of the scheduled in-clinic visits and at-home assessments*). Patients who discontinued a parent study prematurely (ie, patients who did not complete the protocol-defined end-of-study visit) cannot enroll into this open-label extension study before the date when the end-of-study visit would have normally occurred. Completion of the entire follow-up period is not required for parent studies where the protocol specifically allows for an earlier transition into the open-label extension, in which case these requirements apply up to the point of this early transition.
    * For at-home assessments (eg, patient reported outcomes by IVRS calls), patients who completed less than 50% of the assessments may be eligible if technical issues (eg, IVRS system malfunction) or other documented objective circumstances
    contributed to missing assessments.
    b. Received study treatment in one the following studies: R668-AD-0914, R668-AD-1026, R668-AD-1117, and R668-AD-1121, irrespective of duration of participation, provided that patients complied with their investigator?s instructions.
    2. Must be >or=18 years of age at screening
    3. Willing and able to comply with all clinic visits and study-related procedures
    4. Able to understand and complete study-related questionnaires
    5. Provide signed informed consent
    Un paciente debe cumplir los siguientes criterios para ser considerado elegible para la inclusión en el estudio:

    1. Haber recibido el tratamiento del estudio en un ensayo clínico previo con dupilumab en la DA y cumplir uno de los siguientes:

    a. Haber completado adecuadamente las evaluaciones necesarias de los períodos de tratamiento y de seguimiento del estudio original (excepto los estudios señalados en b), de acuerdo a su definición en dicho protocolo original; en concreto, los pacientes deberán haber completado la visita de valoración principal y como mínimo el 50% de las visitas programadas al centro y de las evaluaciones domiciliarias*). Además, los pacientes que hubieran abandonado prematuramente el estudio original (es decir, los pacientes que no hayan completado la visita de fin del estudio definida por el protocolo) no podrán participar en este estudio de extensión abierto antes de la fecha en la que hubiera tenido lugar normalmente su visita de fin del estudio. No se precisa que hayan completado todo el período de seguimiento en el caso de aquel estudio original en el que el protocolo permita específicamente la transición del paciente a la extensión abierto, en cuyo caso estos requisitos sólo serán aplicables hasta donde lo permita esta transición prematura.
    *En cuanto a las evaluaciones domiciliarias (por ejemplo, desenlaces comunicados por los pacientes a través del IVRS), podrían ser elegibles los pacientes que hayan completado menos del 50% de las evaluaciones si ello se debiera a problemas técnicos (por ejemplo, mal funcionamiento del sistema IVRS) u otras circunstancias objetivas documentadas.
    b. Haber recibido tratamiento en uno de los siguientes estudios: R668-AD-0914, R668-AD-1026, R668-AD-1117, R668-AD-1021 y R668-AD-1121, independientemente de la duración de su participación, siempre que el paciente haya cumplido con las instrucciones recibidas durante el estudio, a juicio del investigador.

    2. Edad: >o=18 años en el momento de la selección.
    3. Deseo y capacidad de cumplir con todas las visitas clínicas y las intervenciones relacionadas con el estudio.
    4. Capacidad de comprender y responder a los cuestionarios del estudio.
    5. Firma del consentimiento informado por escrito.
    E.4Principal exclusion criteria
    A patient who meets any of the following criteria will be excluded from the study:
    1. Patients who, during their participation in a previous dupilumab clinical trial, developed a serious adverse event (SAE) deemed related to dupilumab*, which in the opinion of the investigator or of the medical monitor could indicate that continued treatment with dupilumab may present an unreasonable risk for the patient.
    2. Patients who, during their participation in a previous dupilumab clinical trial, developed an AE that was deemed related to dupilumab* and led to study treatment discontinuation, which in the opinion of the investigator or of the medical monitor could indicate that continued treatment with dupilumab may present an unreasonable risk for the patient.
    3. Conditions in the previous dupilumab study consistent with protocol-defined criteria for permanent study drug discontinuation, if deemed related to dupilumab* or led to investigator - or sponsor-initiated withdrawal of patient from the study (eg, non-compliance, inability to complete study assessments, etc.).
    *Note for exclusion criteria # 1, 2, and 3: In studies that are still blinded, conditions deemed related to the study treatment will be considered related to dupilumab.
    4. Treatment with an investigational drug, other than dupilumab, within 8 weeks or within 5 half-lives (if known), whichever is longer, before the baseline visit.
    5. Treatment with immunosuppressive/immunomodulating drugs (eg, cyclosporine, mycophenolate-mofetil, IFN-?, azathioprine, methotrexate, JAK inhibitors) within 1 week before the baseline visit, or any condition that, in the opinion of the investigator, is likely to require such treatment(s) during the first 4 weeks of study treatment in the current study.
    6. Treatment with immunomodulating biologics, other than dupilumab, within 5 half-lives (if known) or 16 weeks (whichever is longer) before the first dose in the open-label extension study.
    7. Treatment with a live (attenuated) vaccine within 12 weeks before the baseline visit.
    8. Planned or anticipated use of any prohibited medications and procedures during study treatment.
    9. Active chronic or acute infection requiring systemic treatment with antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals within 2 weeks before day 1 visit, or superficial skin infections within 1 week before the screening visit. NOTE: patients may be rescreened after the infection resolves.
    10. Known or suspected immunodeficiency, including history of invasive opportunistic infections (eg, tuberculosis, histoplasmosis, listeriosis, coccidioidomycosis, pneumocystosis, aspergillosis) despite infection resolution, or otherwise recurrent infections of abnormal frequency as judged by the investigator.
    11. Known history of human immunodeficiency virus (HIV) infection or HIV seropositivity (HIV testing is not required at screening for patients with a negative HIV result within the past 1 year prior to baseline).
    12. Known history of positive hepatitis B surface antigen (HBsAg) or hepatitis C antibody (HBsAg or hepatitis C testing is not required at screening for patients with a negative result within the past 1 year prior to baseline).

    Exclusion criteria 13-23 (see study protocol)
