Allergy Immunotherapy Market

2020 Analysis and Review: Allergy Immunotherapy Market by Product - SLIT Tablets, Oral, and Injections for 2020 - 2030


Allergy immunotherapy is a treatment to prevent allergic reactions caused by food, grass pollen, dust, and bee venom among other causes. Allergy immunotherapy aids in controlling symptoms among people suffering from allergies such as rhinitis, asthma, and conjunctivitis, among other common allergies.

Allergy immunotherapy involves injections on a regular basis that generally increase the dosage to develop the resistance in the patient. With a progressive increase in dosage, the patient's immunity system becomes less fragile due to the increased production of blocking antibodies that fight the foreign substances that cause allergies.

At present, there are three main types of allergy immunotherapy products in use, namely sublingual allergy immunotherapy (SLIT), subcutaneous allergy immunotherapy (SCIT)/injection, and oral allergy immunotherapy. Among these, SLIT offers treatment without injections, instead treating the allergies with tablets.

Tablets used in the SLIT treatment are used to treat allergies caused by ragweed, grass pollen, and dust mites, and are approved by the US Food and Drugs Administration (FDA). However, SLIT offers treatment for only one type of allergen and does not prevent curbing the possibility of developing other kinds of allergies.

This gives an edge to SCIT treatment, which is considered the most effective form of allergy immunotherapy since it simultaneously prevents the development of asthma and other allergies. As people across the world grow highly sensitive to different types of allergies, the proliferating need for effective fighting methodologies will drive the market on a positive growth trajectory.

Increasing Incidence of Allergies Calls for Efficient Treatments

The rising prevalence of allergies year-on-year worldwide is propelling demand for effectual allergy immunotherapy. For instance, allergic rhinitis is among one of the most common allergies in the world, affecting roughly 10% to 30% of the global population.

According to the estimates of the American Academy of Allergy Asthma & Immunology, nearly 7.8% of the American population aged above 18 develop allergic rhinitis.

Likewise, in 2012, over 17.6 Mn adults and 6.6 Mn children were reported to be diagnosed with rhinitis. The number grew to 20 Mn adults in 2015, thus creating demand for treatments that improve the lifestyle and offer relief from the effects of the allergy.

Along similar lines, other allergies such as asthma, skin allergies, and food allergies, are also quite prevalent across the world and continue to drive demand for immunotherapy.

In 2016, the World Health Organization (WHO) estimated that over 339 people suffer from asthma globally and attributed more than 400,000 deaths to asthma in that year. By the same token, Food Allergy Research & Education (FARE) reported that over 32 Mn people in the US suffer from food allergies, necessitating emergency medical care for one person in every 3 minutes to seek.

Similarly, new research by the Journal of Allergy and Clinical Immunology (JACI) estimated that 2-37% of the European population has a self-reported food allergy. As people become increasingly aware of the availability of these treatments, an increasing number of people are willing to seek treatment, driving the allergy immunotherapy market on a remunerative path.

High Demand for Advanced Procedures

The growing incidence of allergies and the subsequent spending on medical treatments are enabling market players to enhance their treatment offerings. Players are enhancing the existing SLIT drugs, which have proven efficient in treating airway allergies, atopic dermatitis, and a few food allergies.

Recent surveys have suggested that SLIT remains a popular choice among consumers over SCIT, despite its limitations, owing to its accessibility. Moreover, it has been noted that the prevalence of food allergy rises 10% every year, leading to higher demand for immunotherapy for food allergies.

By the same token, oral immunotherapy is gaining prominence among medical professionals and patients, especially in the treatment of allergic rhinitis. Oral immunotherapy is majorly used to control the incidence of allergic reactions caused by accidental or unintentional allergen exposures for individuals with minimal levels of tolerance. On this premise, market players are focusing on improving their offerings on the oral immunotherapy front.

On the other hand, macroeconomic factors such as increasing levels of pollution, changing eating habits, and increased consumption of alcohol are resulting in increased prevalence of skin and other allergies, further boosting the need for allergy immunotherapy.

Key Challenges: High Cost and Side Effects

Allergy immunotherapy is a longer process than conventional therapies, prolonging for 3 to 5 years based on the type and severity of the allergy. It is likely to instigate patients to discontinue halfway through the treatment, owing to financial constraints during the process. This is expected to pose a challenge to the growth of the market to an extent.

On these lines, it is to be noted that allergy immunotherapy is relatively more expensive than traditional medication therapies due to the lengthy nature. The annual cost of allergy treatment is around $1000, with oral therapy costing $4000, while SLIT going beyond $7000. As a result, patients rely on healthcare insurance to cover their expenses. When not covered under insurance, those who cannot afford the treatment have no other option but to resort to temporary medication. The high cost of the treatment is limiting the adoption, thereby hindering the overall growth.

On the other hand, the side-effects of these treatments are expected to hold back the growth. Approximately 1.5% of patients undergoing oral immunotherapy experience side effects such as respiratory, gastrointestinal, or skin-related disorders, thus further restraining the healthy growth of the market.

Region-wise Analysis

Europe Allergy Immunotherapy Market

Europe is expected to remain the largest regional market for allergy immunotherapy during the assessment period, accounting for more than half of the global market value. The region's dominance is attributed to the presence of a wide population base with various allergies. The European Academy of Allergy and Clinical Immunology (EAACI) reports that over 150 Mn people, representing 20% of the region's population, currently suffer from chronic food allergies.

Allergic rhinitis and asthma have been identified as the most common allergies, affecting 100 Mn and 70 Mn people respectively. Furthermore, the organization reported that by 2025, 50% of Europe’s population will be affected by allergies, thus creating a lucrative growth opportunity for the allergy immunotherapy market.

By the same token, the prevalence of allergies in Europe is also mounting into a huge economic burden, due to consequential productivity losses in European nations. On the back of these factors, European governments and bodies including EAACI are working on raising awareness among people and are calling for better medical education and treatments, thereby positively influencing the growth of the market in the region.

North America Allergy Immunotherapy Market

Although North America holds a relatively lower share than Europe, it will remain the second most lucrative region through the assessment period. The US is poised to remain at the forefront of the North American market, accounting for the majority of market value owing to the high prevalence of allergies in the region.

As per the estimates of the American College of Allergy, Asthma (ACAAI), allergies are the sixth leading cause of chronic illness in the US, affecting more than 50 million people and resulting in expenses worth more than US$ 18 Bn every year.

Moreover, children are at a higher risk of allergies. According to the 2014 National Health Interview Survey (NHIS), 8.4% of US children under age 18 suffered from allergic rhinitis, 10% from respiratory allergies, 5.4% from food allergies, and 11.6% from skin allergies.

Due to the aforementioned facets, the demand for allergy immunotherapy will prevail high for the years to come.
