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.

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.

Q3 · MEDICINE

Article

Author: Lee, Yu-Mi ; Cho, Kyu-Sup ; Kim, Ji-A ; Yi, Keun-Ik ; Kim, Sung-Dong ; Mun, Sue-Jean

OBJECTIVESublingual immunotherapy (SLIT) has been considered as an effective and safe alternative to the subcutaneous route. However, different modalities and administration methods may lead to significant changes in their adherence and clinical outcomes. The purpose of this study was to compare the adherence, efficacy, and side effects of SLIT medicines: SLITone^®, Lais^®, and Staloral^®.SUBJECTS AND METHODSEighty-two patients suffering from AR symptoms and sensitized only to house dust mite allergens were included. The patients were treated with SLITone^®, Lais^®, or Staloral^®. Treatment outcomes related to efficacy, dropout rate, and adverse events were evaluated. The visual analogue scale (VAS) including sneezing, rhinorrhea, nasal obstruction, and itching was scored from 0 (normal) to 10 (severe), before and after SLIT. Dropout rate was defined as the number of patients who discontinue SLIT of oneself compared to the number of patients who receive SLIT.RESULTSAll of the nasal symptoms and total symptom scores were significantly decreased in SLITone^®, Lais^®, and Staloral^®. Furthermore, there were significant difference in the improvement of rhinorrhea and TNSS between SLITone^® and Staloral^® group (p = 0.011 and p = 0.001, respectively). Four patients out of 26 in SLITone^® group, 4 patients out of 30 in Lais^® group, and 11 patients out of 26 in Staloral^® group have stopped SLIT of themselves. The dropout rate was significantly higher in the Staloral^® group than other two groups (p = 0.024). Only one patient complained adverse reaction such as swelling of mouth floor in the Staloral^® group.CONCLUSIONAlthough all three SLIT medicines are effective in improving AR symptoms, the adherence to SLIT assessed in accordance with dropout rate was the lowest in the Staloral^®.

ALK’s European registration application for ITULAZAX® for paediatric indication accepted for review

ALK (ALKB:DC / OMX: ALK B / AKBLF) today announced that the European regulatory filing for ITULAZAX® (tree sublingual allergy immunotherapy (SLIT) tablet) in young children has been accepted for review by the relevant health authorities. The European regulatory review process is anticipated to take up to nine months so that, subject to approval, the first market introductions in Europe could take place from the first half of 2025. The data used in the European filing include results from a successfully completed Phase 3 clinical trial involving 952 children in Canada and Europe. The trial was a Phase 3, randomised, placebo-controlled trial to study the efficacy and safety of ITULAZAX® in children aged 5 to 17 with a clinical history of moderate to severe allergic rhinitis and/or conjunctivitis induced by pollen from birch trees and other trees in the birch homologous group. The trial achieved its primary endpoint confirming an overall improvement of 22% compared to placebo. Results were highly statistically significant. ALK’s Executive Vice President of Research and Development, Henriette Mersebach, says: “I’m pleased that our registration application for ITULAZAX® for young children has been accepted for review, and we look forward to the dialogue with the European authorities. The results in children are robust and consistent with previous trial results and this filing represents an important step forward for our ability to transform the medical treatment of children with tree pollen allergy as well as for ALK’s long-term growth ambitions.” Globally, it is estimated that more than 10 million children have uncontrolled respiratory allergies, and the number is growing. Tree pollen is a common cause of these uncontrolled allergies. In Europe, the ITULAZAX® tablet is currently approved for treatment of patients aged 18-65.

ALK completes first part of phase 1 trial with peanut SLIT-tablet

The trial now progresses into its second part, expected to complete later in 2024. ALK to submit a protocol amendment for Phase 1-2 efficacy trial extension. ALK (ALKB:DC / OMX: ALK B / AKBLF) announced today that it has completed the first part of its phase 1 clinical trial (named ‘ALLIANCE’) for its investigational sublingual immunotherapy (‘SLIT’) tablet for the treatment of peanut allergy. The first part of the trial investigated the safety and tolerability of 14 days treatment with the peanut tablet at different starting doses. For all dose levels, the peanut tablet was shown to be safe and tolerable and with a safety and tolerability profile in accordance with that of the approved SLIT-tablets (ACARIZAX/ODACTRA®, GRAZAX®/GRASTEK®, RAGWIZAX®/RAGWITEK®, ITULAZAX®/ITULATEK®). No serious adverse events and no cases of treatment emergent anaphylaxis were reported. Based on results from part 1, the starting dose for the second part of the study has been selected. This part of the study will evaluate the safety and tolerability of up-dosing to the highest tolerable maintenance dose. The second part will be initiated imminently and is scheduled to complete later in 2024. Furthermore, ALK has decided to amend the ALLIANCE study protocol to include a third part involving approximately 100 additional patients. This part will evaluate safety and efficacy of the peanut SLIT-tablet as assessed by an oral food challenge following a period of maintenance treatment. The implementation of the third part is contingent upon a successful outcome of the second part. The revised protocol is expected soon to be submitted to the relevant authorities. ALK’s Executive Vice President of Research and Development, Henriette Mersebach, says: “We are pleased to report positive progress in our ALLIANCE trial, addressing potentially life-threatening peanut allergy. Encouraged by the initial results for the peanut tablet, we have made a provisional decision to extend the trial into a seamless Phase 1-2 design allowing us to explore the efficacy of the tablet as well. Leveraging our profound R&D expertise, we remain committed to developing valuable new treatment options for people with allergy”. In the USA, peanut allergy affects up to 1.5 million children and adolescents aged 4-17, while in Europe, around 1 million children and adolescents are affected by this potentially life-threatening condition. The disease often presents in early childhood and can last a lifetime. For some of these patients, allergy immunotherapy may become a relevant treatment option with the potential to improve quality of life, both for them and their families. This announcement is not expected to materially change the R&D cost outlook for 2024-25.

About the ALLIANCE trialInitiated in 2022, the ALLIANCE trial was designed to assess the tolerability and safety of an up-dosing regimen with a once-daily peanut SLIT-tablet in adults, adolescents, and children. The trial is a phase I, open-label, dose-escalation, multi-site trial conducted in North America, with approximately 100 participants with peanut allergy confirmed by screening via a double-blind, placebo-controlled food challenge. The first part of the trial aimed at determining the starting dose of the up-dosing regimen and the second part to assess safety and tolerability of the up-dosing regimen as well as gather early data on its biological action. The third part intends to investigate safety and efficacy of selected doses of the peanut SLIT-tablet compared with placebo. The trial marked the formal start of ALK’s clinical development of a novel food allergy treatment which uses the same technology as ALK’s SLIT tablets for respiratory allergies.
