    .

    Xeljanz is an oral JAK inhibitor.

    Now, the CHMP’s opinions will be submitted to the European Commission (EC) for review, which is expected to make a final review decision on the abrocitinib and Xeljanz applications by the end of this year
    .


    If the EC grants centralized marketing authorization, it will be valid in all EU member states, Iceland, Liechtenstein, and Norway


    Dr.
    Michael Corbo, Chief Development Officer of Inflammation and Immunology, Pfizer Global Product Development, said: “The positive recommendations of CHMP bring us closer to the goal of helping patients with moderate to severe atopic dermatitis in Europe alleviate symptoms
    .


    We look forward to working with the European Commission.


    Dr.
    Diamant Thaci of the Comprehensive Center for Inflammation Medicine at the University of Lubeck, Germany, said: “Atopic dermatitis is an inflammatory disease that affects the daily lives of millions of people
    .

    Atopic dermatitis (AD) is a chronic skin disease characterized by skin inflammation and skin barrier defects.
    It is characterized by skin erythema, itching, hardening/papule formation, and exudation/scabbing
    .


    The disease is a serious, unpredictable, and usually debilitating skin disease that will have a significant impact on the daily lives of patients and their families


    The active pharmaceutical ingredient of Cibinqo is abrocitinib, which is an oral small molecule that can selectively inhibit Janus kinase 1 (JAK1)
    .


    Inhibition of JAK1 is believed to regulate a variety of cytokines involved in the pathophysiological process of atopic dermatitis (AD), including interleukin (IL)-4, IL-13, IL-31, IL-22 and thymic stromal lymphocyte production Plain (TSLP)


    In September of this year, Cibinqo was approved in the United Kingdom and Japan for the treatment of adolescents and adults with moderate to severe atopic dermatitis (AD) who are suitable for systemic treatment, have insufficient response to existing therapies, and are 12 years of age and older
    .


    At present, abrocitinib's listing application has been submitted to many countries and regions around the world for review, including the United States, Australia and the European Union


    In a number of clinical trials, abrocitinib has a strong effect in relieving the symptoms and signs of AD, including rapidly reducing the symptoms of itching and removing skin lesions
    .


    In particular, in the head-to-head Phase 3 JADE DARE (B7451050) study, compared with the subcutaneous injection preparation Dupixent (Chinese trade name: Dabituo, generic name: dupilumab), abrocitinib was evaluated in every evaluation All of the curative effect indicators are statistically superior
