A Study Investigating the Immunologic Effects and Safety of 60-day Treatment of the ALK HDM Tablets in Adult Subjects With HDM-Induced Allergic Rhinitis and/or Atopic Asthma

NCT ID: NCT02596321

Last Updated: 2018-03-01

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 112 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2015-10-31
• Study Completion Date: 2016-06-30

Brief Summary

To demonstrate superiority of ALK HDM tablets versus placebo in immune response, measured as change of D.farinae specific immunoglobulin G4 (IgG4) from baseline to end of treatment with ALK HDM tablets given once daily over 60 days.

Detailed Description

To demonstrate superiority of ALK HDM tablets versus placebo in the immune response, measured as change of D. Farinae specific IgG4 from baseline to end of treatment with ALK HDM tablets given once daily over 60 days

To evaluate the immune response, measured as change of D. pteronyssinus, D. farinae specific immunoglobulin E (IgE) and D. pteronyssinus specific IgG4 from baseline to end of treatment with ALK HDM tablets given once daily over 60 days, compared to placebo

To evaluate in patients with HDM-allergic respiratory disease the safety and tolerability of 60-day treatment with ALK HDM tablets compared to placebo

• Patient one of the following:

1. Male

2. Female, infertile

3. Female, with a negative pregnancy test and willingness to practice appropriate contraceptive methods until treatment with study drug has been discontinued.

• Patient willing and able to comply with study protocol

Exclusion Criteria

• Previous treatment with HDM immunotherapy for more than 1 month within the last 5 years
• Ongoing treatment with any allergen-specific immunotherapy product
• Reduced lung function (defined as Forced expiratory volume in 1 second (FEV1) < 70% of predicted value after adequate pharmacologic treatment) measured at Visit 1 and Visit 2
• Clinical history of uncontrolled asthma within 3 months prior to the screening visit
• Having experienced a severe asthma exacerbation within 3 months prior to screening visit
• Symptoms of or treatment for upper respiratory tract infection, acute sinusitis, acute otitis media or other relevant infectious process at randomization
• Inflammatory conditions in the oral cavity with severe symptoms such as oral lichen planus with ulcerations or severe oral mycosis at randomization
• History of anaphylaxis with cardiorespiratory symptoms (immunotherapy, exercise-induced, food allergy, drugs or an idiopathic reaction)
• History of recurrent generalized urticaria (defined as two or more episodes) during the last 2 years
• A history of drug induced (incl. immunotherapy) facial angioedema or a family (parents and siblings) history of hereditary angioedema
• Any chronic disease (e.g. cystic fibrosis, malignancy, malabsorption or malnutrition, renal or hepatic abnormality or any other diseases that in the opinion of the investigator would interfere with the study evaluations or the safety of the subject)
