Clinical efficacy and tolerability for allergen specific immunotherapy (AIT) with Itulazax (birch pollen extract tablet) is well established.
Allergen challenges are used by clinicians to confirm correct diagnosis and by researchers to evaluate the efficacy of different interventions, eg. AIT. The challenge is performed by using a specific controlled administration schedule of an allergen product in the shock organ (nose, eye, or airway) and then monitor the result. Nasal Allergen Challenge (NAC) is the most common allergen challenge used.
Aquagen SQ (birch pollen extract) has since decades been golden standard for this purpose, but production of this product ended 2019. Clinicians as well as researchers are now in need for an alternative product.
To evaluate a new method for NAC would be of value from a clinical- and research perspective. From a Nordic perspective a NAC study with dissolved Itulazax would be of special interest since birch allergy is a dominant allergen in the region. In a recently published article it was shown that dissolved Grazax and Aquagen Phleum pratense gave comparable result used in grass allergic patients. Therefore, it seems reasonable to assume that the same method could be used with dissolved Itulazax.
The aim of this clinical trial is to evaluate the feasibility of nasal allergen challenge tests with dissolved Itulazax tablets. The main benefit of this proposal is that the allergen composition of the provocation test product is the same as the final product to be treated with. This is likely to increase the treatment motivation of the patient. In addition, the dissolving process is easier for the physician compared to the dissolving of the previously used Aquagen.

Efficacy and safety of SQ house dust mite sublingual immunotherapy-tablet (12 SQ-HDM) in children with allergic rhinitis/rhinoconjunctivitis with or without asthma (MT-12): a randomised, double-blind, placebo-controlled, phase III trial

Article

Author: Novakova, Silviya ; Østerdal, Anne Sofie ; Foss-Skiftesvik, Majken Hougaard ; Emeryk, Andrzej ; Gagnon, Remi ; Caimmi, Davide ; Nolte, Hendrik ; Schuster, Antje ; Mikler, Jan ; Pfaar, Oliver

BackgroundAllergic rhinitis/rhinoconjunctivitis (AR/C) induced by house dust mites (HDM) often begins in childhood and negatively impacts a child's quality of life. The daily burden can be further compounded by comorbid asthma. Allergen immunotherapy is the only available treatment targeting the underlying cause of allergic disease. Efficacy and safety of the SQ HDM sublingual immunotherapy (SLIT)-tablet has been demonstrated in adults and adolescents with HDM AR/C with or without asthma, but data are lacking for younger children.MethodsPhase III, randomised, double-blind, placebo-controlled trial in younger children (5-11 years) with HDM AR/C with or without asthma. Eligible subjects were randomised 1:1 to SQ HDM SLIT-tablet or placebo for ∼1 year and had free access to AR/C symptom-relieving medications. The primary outcome was the total combined rhinitis score (TCRS) during the final 8 weeks of the treatment period (∼1 year). Secondary outcomes included the rhinitis daily symptom score (DSS) and medication score (DMS), the rhinoconjunctivitis total combined score (TCS), and the Paediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) score. Efficacy analyses were conducted on the full analysis set (observed cases). Asthma-related outcomes were also explored. The trial was registered on ClinicalTrials.gov: NCT04145219 and EudraCT: 2019-000560-22.FindingsA total of 1460 subjects were randomised to SQ HDM SLIT-tablet (n = 729) or placebo (n = 731). The primary outcome, TCRS, was statistically significantly different for SQ HDM SLIT-tablet (n = 693) versus placebo (n = 706), with an absolute difference of 1.0 (95% CI: 0.5, 1.4; p < 0.0001) corresponding to a relative reduction of 22.0% (95% CI: 12.0, 31.1). Key secondary outcomes (DSS, DMS, TCS, PRQLQ) showed statistically significant reductions in symptoms and medication use, and improved disease-related quality of life for SQ HDM SLIT-tablet versus placebo. Improvements in asthma symptoms and reduced asthma medication use indicated an additional effect of SQ HDM-SLIT tablet versus placebo. The SQ HDM SLIT-tablet showed a higher event rate for treatment-related adverse events (AEs) than placebo. Most events were of mild or moderate severity and few subjects discontinued due to AEs (2.5%).InterpretationThe trial confirmed the efficacy and safety of the SQ HDM SLIT-tablet for treating HDM AR/C in younger children (5-11 years) with or without asthma. The safety profile supports daily self-administration of the SQ HDM SLIT-tablet in children.FundingALK-Abellό, Hørsholm, Denmark.

Utility of silver birch and house dust mite extracts derived from licensed sublingual tablets for nasal allergen challenge

Article

Author: Gil, Ana Jimenez ; Olivieri, Bianca ; Scadding, Guy ; Durham, Stephen R ; Stoenchev, Kostadin

AbstractBackgroundNasal allergen challenge (NAC) is used to investigate the effects of allergen exposure and assess treatment efficacy in allergic rhinitis (AR). This study aims to establish dose‐responses to NAC using licensed silver birch (SB) pollen and house dust mite (HDM) sublingual tablets as sources of the allergen extracts in participants with AR.MethodsSixteen volunteers with HDM‐induced perennial AR and 15 volunteers with SB pollen‐induced seasonal rhinitis underwent a graded up‐dosing NAC with extracts derived from HDM allergen (Acarizax®) and SB (Itulazax®) tablets, respectively. Total nasal symptom score (TNSS, range 0–12) and peak nasal inspiratory flow (PNIF) were recorded before, at 10 min and at the end of the NAC. The dose of each allergen that provoked a TNSS of at least 7 (“provoking dose 7”) in most allergic participants was identified. NACs using the “provoking dose 7” were performed on 5 non‐allergic individuals to test for irritant effects. The “provoking dose 7” of HDM extract was used in a subgroup of two SB allergic, non‐HDM allergic, volunteers, and vice versa for SB extract, to test for allergen specificity of the responses.ResultsMost patients experienced a TNSS of at least 7/12 at a median concentration of 1500 AU/mL for both SB pollen and HDM. The average decline in PNIF at this dose was 63.15% for SB and 63.99% for HDM. NACs using the 1500 AU/mL concentrations were performed on 5 non‐allergic individuals with no symptomatic or PNIF response. 1500 AU/mL of HDM extract produced no symptoms in SB allergics nor 1500 AU/mL SB extract in HDM allergics.ConclusionFor both SB and HDM extracts, the optimal allergen dose for NAC to cause a moderate‐severity response (“provoking dose 7/12”) was 1500 AU/mL. Licensed sublingual allergen tablets provide a readily available and inexpensive source of SB and HDM extracts for use in future interventional studies in AR.

ITULAZAX^® versus Alutard SQ^® in the treatment of allergic rhinitis induced by pollen from the birch homologous group: A cost‐minimization modeling analysis from the Danish societal perspective

Article

Author: Brandi, Henrik ; Rønborg, Steen M. ; Grand, Tobias Sydendal ; Pollock, Richard F.

AbstractBackground and aimsAllergic rhinitis (AR) is an inflammatory disorder triggered by an allergic immune response to inhaled allergens. Birch pollen is the major allergenic tree pollen in parts of Europe. ITULAZAX® is a sublingual immunotherapy tablet for the treatment of adults with moderate‐to‐severe AR and/or conjunctivitis induced by pollen from the birch homologous group. The aim was to compare the costs of treating AR with ITULAZAX® versus subcutaneous ALUTARD SQ® Betula verrucosa (ALUTARD SQ®) from a Danish societal perspective.MethodsA cost‐minimization model was developed to capture costs of allergy immunotherapy (AIT), interactions with healthcare professionals (HCPs) in three different care settings (general practice, allergy specialist, and hospital), and indirect costs arising from absenteeism and presenteeism. The cost‐minimization analysis was conducted over a 3‐year time horizon with costs reported in 2021 Danish Kroner (DKK) and Euros (EUR) based on the European Central Bank 365‐day average exchange rate. One‐way sensitivity analyses were performed.ResultsThe base case analysis showed that the total cost of treatment over 3 years was estimated to be DKK 49,117 (EUR 6598) per patient with ALUTARD SQ®, compared with DKK 30,996 (EUR 4164) with ITULAZAX®, reflecting a cost saving of DKK 18,121 (EUR 2434) per patient with ITULAZAX® over 3 years. Over the 3‐year time horizon, costs of AIT were predicted to increase by DKK 17,928 (EUR 2408) with ITULAZAX®, while costs of interactions with HCPs were predicted to decrease by DKK 22,528 (EUR 3027) versus ALUTARD SQ®, more than offsetting the increased cost of ITULAZAX®.ConclusionsGiven the equivalent effectiveness of the two AIT products, and the cost savings with ITULAZAX® versus ALUTARD SQ® from a Danish societal perspective, ITULAZAX® should be considered as a cost‐saving alternative to ALUTARD SQ® for the treatment of birch pollen‐induced moderate‐to‐severe AR in adults.

FDA approves ODACTRA® for the treatment of house dust mite allergy in young children

ALK (ALKB:DC / OMX: ALK B) today announced that the US Food and Drug Administration (FDA) has approved ALK’s ODACTRA® tablet for use in young children with house dust mite (HDM) allergy. ODACTRA® is now indicated to treat HDM-induced allergic rhinitis, with or without conjunctivitis, in children aged five through 11, in addition to patients aged 12 through 65. ODACTRA® is an allergy immunotherapy (AIT) tablet which dissolves under the tongue and helps patients reduce their allergy symptoms and their reliance on symptomatic medication. The FDA approval is an important step in ALK’s efforts to make all its respiratory tablets available for all age groups – children, adolescents, and adults - in all relevant markets. ALK’s Executive Vice President of R&D, Henriette Mersebach (MD), says: “I’m very pleased with the FDA approval of ODACTRA® in young children, as this will enable us to provide an important and potentially life-changing treatment option for children who experience troublesome symptoms and impaired quality of life related to their allergic disease. Building upon our longstanding commitment to developing evidence-based innovative medicines, we now look forward to making ODACTRA® available for children through our US prescriber networks and through commercial and government markets.” The data that formed the basis for the approval includes results from the largest-ever paediatric AIT Phase 3 clinical trial, MT-12, which involved 1,460 children in North America and Europe. The trial demonstrated efficacy and safety of the treatment in children, and the results were recently published in the reputable scientific journal, The Lancet Regional Health – Europe. Globally, it is estimated that more than ten million children, aged five to 11, have uncontrolled respiratory allergies and the number is growing. House dust mites are a common cause of allergy and closely linked to asthma. ALK’s house dust mite allergy tablet is marketed as ODACTRA® in USA, as ACARIZAX® in Europe and several international markets, as MITICURE™ in Japan, and as Sensimune™ in India. Until now, the tablet has been approved for use in young children in Europe and in Japan. A corresponding regulatory review is currently ongoing in Canada. Furthermore, a separate regulatory review of ALK’s tree tablet ITULAZAX® also for use in children is currently ongoing in Europe and Canada. These reviews are expected to complete in 2025, after which all ALK’s tablets will be approved for children, adolescents, and adults in relevant markets. The approval is not expected to affect ALK’s financial outlook for 2025.

ALK’s house dust mite tablet (ACARIZAX®) now recommended by NICE for use in the UK health system

ALK (ALKB:DC / OMX: ALK B / AKBLF) today announced that the National Institute for Health and Care Excellence (NICE) has recommended the use of ACARIZAX® for the treatment of persistent, moderate to severe house dust mite allergic rhinitis in adults and adolescents. The recommendation paves the way for patients to gain access to ACARIZAX® through the National Health Service (NHS) systems in England, Wales, and Northern Ireland, now making it eligible for general reimbursement. ACARIZAX® is the first sublingual allergy immunotherapy (AIT) product to be assessed and recommended by NICE, and the treatment will be the first of its kind to become widely available through the National Health Service (NHS) systems. The UK is currently one of the few European markets, where ALK’s allergy tablets are authorised without adequate public reimbursement. Additionally, there is a significant underutilisation of AIT in the UK compared to other European countries. ALK’s Executive Vice President of Commercial Operations, Søren Niegel, says: “Today’s news marks a milestone for ALK. NICE’s methodologies and guidelines are widely regarded as the gold standard, and we are proud to become the first and only company to make sublingual allergy immunotherapy tablets widely accessible in the United Kingdom for the benefit of the many patients whose lives are profoundly impacted by allergy.” Allergic rhinitis disease is a prevalent condition in the UK, affecting 26% of adults. Among these, house dust mite is the most common airborne allergy, affecting approximately half of those living with allergic rhinitis disease – upwards of 5 million people in the UK. Despite a range of symptomatic treatment options, approximately one million people still live with debilitating and uncontrolled symptoms. NICE conducts reviews to assess the clinical benefits and cost-effectiveness of healthcare interventions, treatments, and technologies. The institute published a Final Draft Guidance on 30 January 2025, appraising the clinical benefits and cost-effectiveness of ACARIZAX® in the treatment of uncontrolled house dust mite allergy. NICE is expected to publish a Final Guidance in March, after which the NHS systems in England, Wales and Northern Ireland are required to implement ACARIZAX® in the treatment practices. ALK also plans to soon submit a similar application for a NICE review of its sublingual tree tablet, ITULAZAX®. Submissions will also be made to extend the approvals for ACARIZAX® and ITULAZAX® to include children. ALK’s current business in the UK mainly focuses on anaphylaxis (treatment of severe allergic reactions) with the adrenaline pen Jext® on the market and the nasal spray EURneffy® due for launch later this year, pending regulatory approval. AIT tablet sales are currently modest, but ALK expects the combination of its anaphylaxis treatments and the tablets to create long-term synergies in parallel with an expanded infrastructure and as more patients become aware of these treatment options. The NICE approval is not expected to affect ALK’s revenue growth in 2025.

ACARIZAX® approved in Europe for treatment of young children

ALK (ALKB:DC / OMX: ALK B) today announced that its European regulatory filing for ACARIZAX® (house dust mite sublingual allergy immunotherapy tablet) in young children aged five to 11 has been approved by the health authorities in 21 EU countries via a type II variation procedure. The first market introductions, including in ALK’s largest market, Germany, are expected to follow over the coming months. The data that formed the basis for the approval includes results from the largest-ever paediatric AIT Phase 3 clinical trial, MT-12, which involved 1,458 children in North America and Europe. MT-12 was a randomised, placebo-controlled trial investigating the efficacy and safety of ACARIZAX® in children aged five to 11 with a clinical history of house dust mite-induced allergic rhinitis/conjunctivitis with or without asthma. The trial demonstrated efficacy and safety of the treatment in children, and the results were recently published in the reputable scientific journal, The Lancet Regional Health – Europe. ALK’s Executive Vice President of R&D, Henriette Mersebach (MD), says: “Today, most children living with allergies are only treated with symptom-relieving medications, such as antihistamines or steroids. Despite this, many children still have uncontrolled symptoms and may benefit from effective treatment options that also address the underlying cause of their disease. Allergy induced by house dust mites often begins in early childhood and is associated with an elevated risk of developing into allergic asthma. Today’s approval marks an important step forward for our ability to transform the medical treatment of children with allergies, as well as for ALK’s long-term growth ambitions”. Globally, it is estimated that more than ten million children, aged five to 11, have uncontrolled respiratory allergies and the number is growing. House dust mites are a common cause of allergy and closely linked to asthma. The house dust mite tablet is marketed as ACARIZAX® in Europe and several international markets, as ODACTRA® in the USA, and as MITICURE™ in Japan. Until now, the tablet has been approved for use in young children only in Japan, where the vast majority of patients receiving treatment are children. In Europe, the tablet is now approved for use in patients aged five to 65 diagnosed by clinical history and a positive test of house dust mite sensitisation (skin prick test and/or specific IgE blood test) with persistent moderate to severe house dust mite allergic rhinitis despite use of symptom-relieving medication. In addition, the tablet is approved for house dust mite-induced allergic asthma in patients aged 18-65. A corresponding regulatory review is currently ongoing with the US Food and Drug Administration. Furthermore, a separate regulatory review of ALK’s tree tablet ITULAZAX® is ongoing in Europe and Canada, also for use in children. These reviews are expected to complete in 2025.
