Prospective, randomised, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of polymerized and mannan conjugated allergen extract of Dermatophagoides for the treatment of allergic rhinitis/rhinoconjunctivitis with or without asthma.
The main objective of the clinical trial is to evaluate the clinical efficacy of the investigational medicinal product, administered sublingually, compared to placebo for the treatment of moderate-severe rhinitis/rhinoconjunctivitis with or without mild to moderate asthma and controlled using the Rhinitis/Rhinoconjunctivitis Combined Symptom and Medication Score (R-CSMS).
Allergen-specific immunotherapy (AIT) has been shown to be effective in relieving symptoms, reducing medication use, and improving quality of life in patients with respiratory allergies). This is thought to be due to the induction of a state of tolerance to specific allergens with long-lasting effects after discontinuation of treatment. And it is accepted that immunotherapy is the only available method for allergists to improve or cure, partially or definitely, an allergic process The study population of this clinical trial will comprise subjects allergic to mites (Dermatophagoides pteronyssinus and/or D. farinae) with symptoms of moderate-severe rhinitis/rhinoconjunctivitis with or without mild to severe controlled asthma, suitable to allergen immunotherapy.
The primary efficacy endpoint will be the combined rhinitis/rhinoconjunctivitis symptom and medication score.
Every single day from the beginning of the administration of the investigational drug (V2-VF), the subject will be asked to score and register his/her symptoms and record medication consumption in an electronic diary following the instructions of the application. This diary will provide the symptom score and medication consumption for each subject during the trial.

During the trial, both the investigator and the subjects included will be unaware of the treatment each subject is receiving.
Blinding is intended to minimize potential biases resulting from differences in treatment or assessment of subjects. It is also intended to reduce as much as possible the interpretation of the results that could arise as a consequence of the investigator or the subject knowing the assigned treatment.
The person in charge of data analysis will also not know the treatment assigned to each subject until the database has been closed.
So that neither the subject nor the investigator will know which treatment each subject is receiving, all trial medication will be identical in outer packaging and appearance.

| 7 months |

| 7 months |
| Security parameters | Global rate and severity of Adverse Events (AE) per administration and per subject | Month 2 and month 7 |

| Number of Systemic Adverse Reactions | Systemic adverse reactions are those that appear in other parts of the body other than the site of administration. Their severity will be classified according to World Allergy Organization, measured according to the following grades:
| 6 months |
| Number of Adverse Reactions to any medication | Number of Adverse Reactions to any medication administered for the treatment of AE/AR | 7 months |
| Treatment adherence | At each visit, a new bottle shall be provided to the subject and the previous bottle shall be collected. The amount remaining in each returned bottle shall be analysed to assess adherence to treatment. | 6 months |
| Compliance of the electronic diary | All subjects included in the trial will download the "ITK Diary Card" app on their mobile phone, which will be used as the subject's electronic diary. Subjects will fill in their symptoms and medication intake. At each visit, the investigator should review the subject's electronic diary to ensure compliance. For the calculation of the main variable, only those subjects that have reported data corresponding to at least 40% of the days will be considered. Therefore, for subjects with less than 40% of the reported data, the main variable cannot be calculated. | 6 months |
