Sublingual Allergy Immunotherapy Market

Sublingual Allergy Immunotherapy Market Outlook (2023 to 2033)

The sublingual allergy immunotherapy (SLIT) market reached US$ 414.5 million in 2022 and is predicted to expand at a CAGR of 9.1% to climb to US$ 1.02 billion by the end of 2033.

• As assessed by Persistence Market Research, the Odactra drug held a market share of 40.1% in 2022.
• Sublingual allergy immunotherapy accounted for 2% share of the global allergy treatment market in 2022.

In recent years, the prevalence of food allergies, allergic rhinitis, and other atopic illnesses like atopic dermatitis and allergic rhinitis has been on the rise.

• As per a 2019 study published in the National Library of Medicine, 20% of the world's population is now collectively impacted by allergic disorders.

Focus on innovation in sublingual immunotherapies in developing nations and increased prevalence of various forms of allergies are primary market drivers.

• According to the CDC (Centers for Disease Control and Prevention), food allergies are increasing rapidly, especially among children. Increasing allergy cases are expected to boost the demand for allergy immunotherapy over the forecast period.

The SLIT market is growing as a result of the expanding accessibility of advanced technology including molecular diagnostics and genetic testing. These innovations enhance patient outcomes by promoting precise diagnosis and individualized therapy planning.

Over the forecast period, market growth is expected to be driven by the increasing acceptance of advanced medical technologies and the rapid expansion of groundbreaking treatments in emerging countries.

Investments in research and technological advancements by key players for the commercialization of allergy immunotherapy products are expected to rise, leading to more advanced and specific treatment options. Manufacturers are directing their efforts toward research to develop immunotherapy treatments for food allergies. More than 40 products are in clinical trials and are expected to be commercialized in the next 2 to 3 years.

Why is Demand for Sublingual Allergy Immunotherapy Skyrocketing?

“Growing Burden of Allergic Diseases and Rising Awareness of Food Allergies”

Prevalence of allergic rhinitis, skin, asthma, insect, medication, or food allergies is increasing significantly.

• As per the American College of Allergy, Asthma & Immunology (2023), more than 50 million people in the United States experience allergic reactions annually, ranking allergies as the sixth most common chronic illness.

For short-term relief, people turn to drugs and sensitization techniques, but there are now just a few treatments available. Consequently, relieving allergy symptoms requires a sustained reliance on drugs. The uptake of these therapies is being aided by the accessibility of cutting-edge diagnostic techniques including serum-specific immunoglobulin E (IgE) testing and skin prick tests.

Food allergy is a critical and expanding public health concern as the prevalence of allergic disorders has dramatically increased in recent years.

• According to insights from Food Allergy Research & Education in 2023, there is an increasing prevalence of food allergies, with approximately 32 million Americans currently experiencing this condition.
• Food Allergy Awareness Week, which is observed by FARE every May, is a full week devoted to educating people and raising awareness about food allergies in general. The market for allergy immunotherapy is anticipated to expand as food allergy awareness rises.

Regulatory approval and commercialization of medications and therapies are creating opportunities for manufacturers. Products containing allergens are sold in several countries around the world, but the laws governing these sales vary. The number of allergic rhinitis treatments on the market has grown as a result of an increase in Abbreviated New Drug Application (ANDA) approvals for these drugs.

These factors are expected to contribute to the demand for more advanced and convenient allergy treatment options such as SLIT.

What are the Hindrances to the Demand Growth for SLIT?

“High Treatment Cost and Unfavourable Side Effects of Some Medications”

Allergy shots are periodic injections administered over a period. Allergy immunotherapy is a lengthy treatment and may continue for up to 3 to 5 years to stop or reduce allergy attacks, depending on the type and stage of allergy.

A tiny amount of the specific substance or compounds that cause allergic reactions are present in each allergy shot. Patients undergoing the treatment usually discontinue the process midway due to prolonged treatment time, age, health, physical location, and budget constraints. This can negatively impact market growth for SLIT.

Allergy immunotherapy is a prolonged process and hence the cost associated with it also becomes a burden for patients.

• Allergy shots, SLIT, and oral therapy (Palforzia) can cost US$ 1,000, US$ 7,000, and US$ 4,000 per year, respectively, if not covered under insurance. Combination therapy is also expensive.

Patients have reported redness or swelling at the injection site and serious reactions such as anaphylaxis. Adverse effects associated with allergy shots and tablets are also limiting the demand for sublingual allergy immunotherapy.
