Title: A Randomised, Double-blind, Placebo-controlled, Multi-centre, Phase III Study to Assess Efficacy and Safety of STALORAL® 300 IR Sublingual Immunotherapy (SLIT) in Chinese Asthmatic Patients Allergic to House-dust Mites
Brief Summary: A phase III study to assess the efficacy and safety of sublingual immunotherapy with STALORAL dust mites solution compared with placebo for reduction of asthma symptoms.


Options:
A: Inclusion Criteria:

1. Male or female outpatients aged 16 to 50 years (inclusive).
2. House dust mite-induced allergic asthma with or without perennial allergic rhinitis for at least 1 year.
3. Sensitised to D. pteronyssinus and D.farinae (positive skin prick test (SPT) with wheal diameter ≥ 4 mm and specific IgE level ≥ 0.70 kU/L
4. Patients treated with inhaled corticosteroids (ICS) before the screening visit at a dose ≥ 200 µg and \< 1,000 µg equivalent budesonide/day.

Exclusion Criteria:

1. Mild intermittent asthma needed to be treated only with β2-agonist (GINA level 1).
2. Severe asthma needed to be treated with inhaled corticosteroids with a dose ≥ 1,000 µg/day equivalent budesonide.
3. FEV1 \< 70% of predicted value at Visit 1.
4. Co-sensitisation to other inhalant allergens than dust mites leading to clinically relevant allergic asthma and proven by a positive skin prick test with wheal diameter ≥ 4 mm and serum specific IgE ≥ 0.70 KU/L .
5. Patients with a past or current disease, which as judged by the investigator, may affect the patient's participation in or the outcome of the study. These diseases include, but are not limited to, past or current cardiovascular disease, malignancy, hepatic disease, renal disease, haematological disease, neurological disease, immunological disease and endocrine disease.
B: Inclusion Criteria:

* History of controlled asthma for the prior 1 month if participant has asthma, defined by not exceeding 2 days of symptoms per week; not more than 2 days of albuterol/short acting beta-agonist \[SABA\] use per week; and not wakening more than twice a month at night due to asthma symptoms
* Agrees to remain abstinent or use (or have their partner use) 2 acceptable methods of birth control from screening and through the duration of the study

Exclusion Criteria:

* Unable to meet medication washout requirements
* History of chronic urticaria and/or chronic angioedema within prior 2 years
* History of anaphylaxis with cardiorespiratory symptoms with prior immunotherapy due to an unknown cause or to an inhalant allergen
* Unstable, uncontrolled or severe asthma, or has experienced a life-threatening asthma attack or an occurrence of any clinical deterioration of asthma that resulted in emergency treatment, hospitalization due to asthma, or treatment with systemic corticosteroids (but allowing SABAs) at any time within prior 3 months
* History of chronic sinusitis during within prior 2 years
* Pregnant or breast-feeding, or expecting to conceive within the projected duration of the study
* Known history of allergy, hypersensitivity or intolerance to investigational medicinal products except for Dermatophagoides pteronyssinus (D. pteronyssinus) and/or Dermatophagoides farina (D. farina) or self-injectable epinephrine
* Business or personal relationship with investigational site personnel or Sponsor who is directly involved with the conduct of the trial
C: Inclusion Criteria:

* Positive RAST result to birch pollen
* Positive Skin Prick Test reaction to birch pollen
* positive nasal provocation test result to birch pollen extract

Exclusion Criteria:

* serious chronic diseases
* other relevant seasonal allergies
D: Inclusion Criteria:

* History of allergic rhinitis/rhinoconjunctivitis to house dust of 1 year duration or more (with or without asthma)
* If female of childbearing potential, has a negative urine pregnancy test at screening and agrees to remain abstinent or use (or have their partner use) 2 acceptable methods of birth control within the projected duration of the study.

Exclusion Criteria:

* Sensitized and regularly exposed to animal dander and molds, (e.g. present in the home, job, etc.)
* Sensitized and regularly exposed to seasonal allergens (i.e., birch or grass pollen)
* Immunosuppressive treatment within 3 months prior to screening (except steroids for allergic and asthma symptoms)
* History of chronic urticaria and/or angioedema within 2 years prior to screening
* Previous immunotherapy treatment with any HDM allergen for more than 1 month within 3 years prior to screening
* Ongoing treatment with any specific immunotherapy
* History of anaphylaxis with cardiorespiratory symptoms with prior immunotherapy, due to an unknown cause or to an inhalant allergen
* Unstable uncontrolled/partially controlled or severe asthma, or life-threatening asthma attack or an occurrence of any clinical deterioration of asthma that resulted in emergency treatment, hospitalization due to asthma, or treatment with systemic corticosteroids (but allowing short-acting beta agonists \[SABA\]) within 3 months prior to screening
* Asthma requiring medium- or high-dose inhaled corticosteroid (ICS) within 12 months prior to screening
* Chronic sinusitis within 2 years prior to screening
* Nasal condition that could confound the efficacy or safety assessments (e.g., nasal polyps)
* Pregnant, breastfeeding or planning to become pregnant during the study
* Participation in a different investigational study at any site during the same time frame of this study
* Direct association with the administration of the study or a family member of the study staff
