Title: A Randomized, Double-blind, Placebo-controlled, Multi-center, Phase III Study of the Efficacy and Safety of 300 IR Sublingual Immunotherapy (SLIT) Administered as Allergen-based Tablets Once Daily to Adult Patients Suffering From Grass Pollen Rhinoconjunctivitis
Brief Summary: The purpose of the study is to assess the efficacy and safety of 300 IR sublingual tablet of grass pollen allergen extract compared to placebo in adult patient with allergic rhinoconjunctivitis.


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:

1. Grass pollen-related allergic rhinoconjunctivitis for at least the last two pollen seasons.
2. Positive SPT to grasses
3. Total symptoms score for the previous pollen season more than 12 out of 18.
4. Patients with FEV1 ≥ 80% of the predicted value.

Exclusion Criteria:

1. Positive SPT to other grasses present during the grass pollen season and if endemic to the region
2. Patients with clinically significant confounding symptoms of allergy to other allergens potentially overlapping the grass pollen season
3. Asthma requiring treatment with medications other than beta-2 inhaled agonists.
4. Patients who have received any desensitization treatment for grass pollen in the past 5 years.
5. Ongoing immunotherapy with any other allergen.
6. Patients with any nasal or oral condition that could confound the efficacy or safety assessments
7. Patients with known history of hypersensitivity or intolerance to any of the excipients in the investigational product (such as lactose intolerance).
8. Patients with any past or current clinically significant condition which as judged by the investigator, may affect the patient's participation or the outcome of the study.
9. Patients treated with systemic or inhaled corticosteroids
10. Patients treated or under treatment with beta-blockers, continuous systemic corticotherapy or immunosuppressive drugs.
11. Pregnant, breastfeeding, or sexually active women who are not using a medically accepted contraceptive method as listed above.
12. Patients participating or having participated within 30 days before Screening in any clinical study.
13. Patients who are unlikely to complete the study for any reason, or patients who have to travel for extended periods of time during the grass pollen season which will compromise the data
14. Patients with history of drug or alcohol abuse.
15. Study staff, investigators, sub-investigators, as well as their children or spouses and family members of all study staff should not be enrolled in the study.
16. Patients will not be randomized in this study more than once.

* 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
