The global atopic dermatitis treatment market was valued at USD 4.85 billion in 2021 and is expected to reach USD 11.34 billion by 2027, growing at a CAGR of 15.20% from 2022-2027. Atopic dermatitis is a chronic, pruritic inflammatory skin condition that typically affects the face (cheeks), neck, arms, and legs but usually spares the groin and axillary regions. Atopic dermatitis, also known as atopic eczema, is a chronic relapsing inflammatory skin condition. Atopic dermatitis is common worldwide. People of all ages, from newborns to adults 65 years and older, live with this condition. Atopic dermatitis is associated with an increased risk of multiple comorbidities, including food allergy, asthma, allergic rhinitis, and mental health disorders. Due to such factors, the atopic dermatitis treatment market is growing immensely during the forecast period.
Atopic dermatitis is the most common type of eczema, affecting approximately 26 million people in the United States. Atopic dermatitis is children's most common skin disease, with prevalence steadily increasing from 8% to 12% in the last two decades. It is characterized by a defect in the skin barrier, which allows allergens and other irritants to enter the skin, leading to an immune reaction and inflammation. This reaction produces a red, itchy rash, most frequently occurring on the face, arms and legs, and the rash can cover significant areas of the body. The rash causes significant pruritus (itching), which can lead to damage caused by scratching or rubbing and perpetuating an ‘itch-scratch’ cycle. Pediatric patients with atopic dermatitis can suffer from sleep disturbances, behavioral problems, irritability, crying, and interference with normal childhood activities and social functioning. Adults with atopic dermatitis also frequently suffer from sleep disturbances, emotional impacts, and impaired social functioning. Arizton estimates that the prevalent cases of atopic dermatitis were high in China, followed by U.S. and Japan in 2020. The increasing prevalence of atopic dermatitis is driving the growth of the atopic dermatitis treatment market.
Atopic Dermatitis Diagnosis
The exact cause of atopic dermatitis is unknown. Currently, no reliable biomarker which can distinguish the disease from other entities. However, the most commonly used biomarker is elevated total and/or allergen-specific serum IgE. The diagnosis of atopic dermatitis is based on the history and physical examination findings. Exposure to possible exacerbating factors, such as aeroallergens, irritating chemicals, foods, and emotional stress, should be investigated. Unfortunately, no specific laboratory findings or histologic features define atopic dermatitis.
Atopic Dermatitis Treatment
Most atopic dermatitis patients are treated with topical therapies, particularly low to mid-potency topical steroids and TCIs. These two classes of drugs constituted nearly all atopic dermatitis prescriptions. Despite their widespread use, existing topical therapies all possess substantial shortcomings:
- Topical corticosteroids, in combination with Vitamin D creams and antihistamines, are the first line of treatment for AD. The topical steroids aim to provide short-term itch relief to break the itch-scratch reflex cycle – the primary cause of reinfection. Although in mild cases, these therapies may be effective, in moderate/severe cases, long-term use (of steroids) tends to do more harm than benefit. Prolonged use damages and dries out the epidermal layer of skin, which, somewhat paradoxically, ends up actually worsening the itch-scratch complex.
- Topical steroids pose a particular concern in pediatric patients due to the risk of systemic absorption, the consequent risk of HPA axis suppression, and potential developmental problems. Chronic use of topical steroids in atopic dermatitis patients is generally avoided.
- Second-line agents include immunosuppressant medications such as topical calcineurin inhibitors, including Pimecrolimus (Elidel) and Tacrolimus (Protopic). Topical calcineurin inhibitors are generally seen as providing less symptomatic improvement than topical steroids and are also associated with some application site burning. In 2005 the FDA placed a boxed warning on the labels of both TCIs regarding a potential increased risk of cancers, especially lymphomas.
- Other treatments include biologics, typically starting with interleukin inhibitors such as tralokinumab-idrm, dupilumab, and nemolizumab.
- Topical treatments include PDE-4 inhibitors such as Crisaborole (Eucrisa) and Difamilast (Moizerto); JAK inhibitors such as Ruxolitinib (Opzelura) and Delgocitinib (Corectim Ointment).
- Oral JAK inhibitors such as Abrocitinib (Cibinqo), Upadacitinib (Rinvoq), and Baricitinib (Olumiant) are used for the treatment of atopic dermatitis.
ATOPIC DERMITIS: CLINICAL TRIALS SCENARIO
The clinical trial portfolio contains 153+ trials in various development phases. Most industry-sponsored drugs in active clinical development for atopic dermatitis are in the Phase II stage. The distribution of clinical trials across Phase I-IV indicates that the vast majority of trials for atopic dermatitis have been in the mid-phase of development, with 47% of trials in Phase I/II & II and only 29% in Phase Phase II/III-III.
MARKET DRIVERS & TRENDS
Increasing Adoption for Biological Therapies
Biological therapies such as anti-interleukin antibodies are widely used for treatment in the atopic dermatitis treatment market. With Dupixent being the biologic approved for atopic dermatitis in 2017, there is a demand for therapies with novel MOAs that are less immunogenic than current offerings. Many new classes of therapies are looking to enter the market over the next few years. The biologics such as interleukin inhibitors are making inroads into the atopic dermatitis market owing to better clinical profiles and convenient patient dosing.
Anticipated Launch of Emerging Drugs
A recent wave of biological products prescribed for treating atopic dermatitis will likely create a lucrative opportunity for growth in the atopic dermatitis treatment market. Despite the plethora of therapies currently available to patients with atopic dermatitis (AD), there is still room for improvement within the treatment space. Arizton anticipates the launch of five new agents among the 8MM, including two interleukin (IL) inhibitors (Lebrikizumab; CM-310), one topical Janus kinase (JAK) inhibitor (Delgocitinib), and two topical phosphodiesterase 4 (PDE-4) inhibitors (Roflumilast and JW-100). Launching these late-stage drugs will create an opportunity for growth in the global atopic dermatitis treatment market.
Focus on Novel Drugs with Novel Mechanism
The therapeutic agents targeting the IL-13/IL-31 axis have been proven to be very effective in AD, some are already in the therapeutic armamentarium, and others are in development. Over the next five years, Arizton expects to see a surge of innovation emerging from the research and development pipeline and a range of technology-enabled transformations that will expand the evidence basis for interventions and bring measurable improvements to outcomes.
