Alopecia Areata - Market Insight, Epidemiology And Market Forecast - 2032

Key Highlights:

• Alopecia areata is a complex, polygenic, autoimmune disorder characterized by patches of non-scarring alopecia affecting the scalp and body hair that can be psychologically devastating. Alopecia areata is clinically heterogeneous, and the course of the disease is unpredictable, with spontaneous regrowth of hair occurring in 80% of patients within the first year and sudden relapse at any given time. Cases beginning during childhood are more severe than cases with an onset during adulthood.
• Typically, an alopecia areata diagnosis can be made based on the pattern of hair loss and the patient's medical history. In some cases, a biopsy is needed to confirm the diagnosis. Recently, dermoscopy (trichoscopy) has emerged as a helpful supporting tool.
• Treatment options for alopecia areata include topical, locally injected, or systemic steroids, contact immunotherapy, topical minoxidil, topical irritants such as anthralin, and systemic immunosuppressants such as cyclosporine or methotrexate. Current and promising investigational treatments include JAK inhibitors, platelet-rich plasma, recombinant IL-2, hydroxychloroquine, simvastatin with ezetimibe, and excimer laser.
• As per DelveInsight's estimates, the prevalent cases of alopecia areata in the US was found to be ~783,100 cases in 2022, which as per DelveInsight's analysts, is expected to increase by 2032.
• Despite limited evidence for the efficacy of therapeutic agents, intralesional and topical corticosteroids are considered first-line treatment for most patients with patchy alopecia areata. Patients with extensive disease, often defined as greater than 50% scalp hair loss, may be treated with topical immunotherapy. This approach avoids the large number of injections that would be otherwise required when using intralesional corticosteroids.

Alopecia Areata Market Outlook

Alopecia areata is a common autoimmune skin disease that causes hair loss on the scalp, face, and sometimes on other body areas. It affects people of all ages, both sexes, and all ethnic groups. As per research, Alopecia areata affects 1 in every 500-1,000 people in the United States. It is one of many recognized forms of alopecia; Alopecia areata is the second most common form after androgenetic alopecia. It often appears during childhood and can be different for everyone.

Alopecia areata treatment involves corticosteroids, topical sensitization therapy, topical irritation therapy, and others. Topical corticosteroids possess fewer side effects and are widely used as a first-line treatment for Alopecia areata; available in different formulations, shampoos, and foams, it is generally well-tolerated with patient compliance for Alopecia areata treatment. Intralesional injection of corticosteroids alone or combined with topical corticosteroids is also recommended for patchy Alopecia areata.

The US FDA has granted BTD and FTD to CTP-543 for Alopecia areata treatment. Recently, the company has announced positive results from two Phase III studies.

The market presents a wide opportunity for these players to capitalize on the untapped market. However, continuous efforts are further needed to develop drugs treating Alopecia areata. Additionally, the goal of the therapy of Alopecia areata is not only to improve clinical symptoms but also to prevent disease progression and ensuing complications, for which both medical and dietary therapy can be useful. Henceforth, the critical area that must be further defined in this field is understanding the pathogenesis of the disease. Since the entire landscape consists of only a single approved drug and off-label therapies, any significant development in this direction is expected to create a tectonic impact on the existing market scenario during the forecast period.

Alopecia Areata Understanding and Treatment

Alopecia Areata Overview

According to the National Alopecia Areata Foundation (NAAF), alopecia areata is a common autoimmune skin disease, causing hair loss on the scalp, face, and sometimes on other areas of the body, affecting people of all ages, both sexes and all ethnic groups can develop alopecia areata. As per research, alopecia areata affects 1 in every 500-1,000 people in the United States. It is one of many recognized forms of alopecia; alopecia areata is the second most common form after androgenetic alopecia. It often first appears during childhood and can be different for everyone who has it.

There are different types of alopecia areata, among which the three main forms include: alopecia areata patchy, alopecia totalis, and alopecia universalis. Persistent patchy alopecia areata, diffuse alopecia areata, and ophiasis alopecia are alopecia areata's other observed clinical variants. Alopecia areata is known as "polygenic disease" due to its genetic predisposition; about 20% of people with alopecia areata have a family history. In alopecia areata, hair loss is mainly due to inflammation caused by an attack of hair follicles by the body's immune system, but the exact cause behind this autoimmune disorder is still unknown.

Alopecia Areata diagnosis

The evaluation of an alopecia areata patient should include a comprehensive medical and family history, and a thorough examination of the scalp, the face, and the entire body, including the nails. This should always be complemented by dermatoscopy and a hair pull test. When clinical findings do not allow a definite diagnosis, additional investigations may be necessary, such as a scalp biopsy, a fungal culture, or serology for other autoimmune diseases or infectious diseases

Alopecia Areata treatment

Current therapies for alopecia areata aim to immunosuppress or immunomodulate the activity of the disease, with generally unsatisfying responses and high relapse rates, especially in more severe cases. Due to the unpredictable course of the disease and the spontaneous remissions often observed within the first year, therapy efficacy is difficult to estimate. Additionally, the available therapeutic options do not influence the long-term course of the disease, and thus an urgent need remains for a novel, more effective therapies. New insights into the pathophysiologic mechanisms in alopecia areata are leading researchers to develop more targeted therapeutic approaches

Topical corticosteroids are widely used in the treatment of limited patchy alopecia areata and as first-line therapy for children because of their low side-effect profile when used discerningly. They are also recommended as adjunctive therapy in more severe forms.

Systemic corticosteroids have been used in the treatment of alopecia areata as oral pulse therapy (PT), intravenous (IV) PT, intramuscularly (IM), or continuously (CT). The reported therapeutic schemes vary between studies.

Qualitative Analysis

We perform Qualitative and Market Intelligence analysis using various approaches, such as SWOT analysis and Conjoint Analysis. In the SWOT analysis, strengths, weaknesses, opportunities, and threats in terms of disease diagnosis, patient awareness, patient burden, competitive landscape, cost-effectiveness, and geographical accessibility of therapies are provided. These pointers are based on the Analyst's discretion and assessment of the patient burden, cost analysis, and existing and evolving treatment landscape.

Conjoint Analysis analyzes multiple approved and emerging therapies based on relevant attributes such as safety, efficacy, frequency of administration, designation, route of administration, and order of entry. Scoring is given based on these parameters to analyze the effectiveness of therapy.

In efficacy, the trial's primary and secondary outcome measures are evaluated; for instance, in trials for Alopecia Areata one of the most important primary endpoints was the proportion of subjects who have not experienced any severe vaso-occlusive crisis, frequency, and severity of collected adverse events (AEs). Based on these, the overall efficacy is evaluated.

Further, the therapies' safety is evaluated wherein the acceptability, tolerability, and adverse events are majorly observed, and it sets a clear understanding of the side effects posed by the drug in the trials. In addition, the scoring is also based on the route of administration, order of entry and designation, probability of success, and the addressable patient pool for each therapy. According to these parameters, the final weightage score and the ranking of the emerging therapies are decided.

Market Access and Reimbursement

Because newly authorized drugs are often expensive, some patients escape receiving proper treatment or use off-label, less expensive prescriptions. Reimbursement plays a critical role in how innovative treatments can enter the market. The cost of the medicine, compared to the benefit it provides to patients who are being treated, sometimes determines whether or not it will be reimbursed. Regulatory status, target population size, the setting of treatment, unmet needs, the number of incremental benefit claims, and prices can all affect market access and reimbursement possibilities.

The report further provides detailed insights on the country-wise accessibility and reimbursement scenarios, cost-effectiveness scenario of approved therapies, programs making accessibility easier and out-of-pocket costs more affordable, insights on patients insured under federal or state government prescription drug programs, etc.
