Plain-language summary
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).

Inclusion criteria
. Signed Informed Consent Form.
. Male or female, aged between 12 and 60 years, both included.
. Confirmed clinical history of inhalation allergy with moderate-severe rhinitis/rhinoconjunctivitis according to the ARIA classification with or without controlled mild-moderate intermittent or persistent asthma according to the definition of GEMA 5.0 y GINA caused by allergy to mites (D. pteronyssinus and/or D. farinae). The asthma diagnostic will be valid up to 24 months prior to signing the informed consent form.
. Combined Symptom and Medication Score for moderate to severe rhinitis/rhinoconjunctivitis (RCSMS) ≥ 1,8 out of 3.
. Positive skin prick test (wheal major diameter ≥ 5 mm) to a standardized allergen extract of Dermatophagoides pteronyssinus and/or Dermatophagoides farinae. The results will be valid up to 12 months prior to signing the informed consent form.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

What they're measuring
1
Rhinitis/rhinoconjunctivitis Combined Symptom and Medication Score (RCSMS)
. Specific IgE against a complete extract of Dermatophagoides pteronyssinus and/or D. farinae or any the molecular components of allergenic sources with a value ≥ 3.5 kU/L. The results will be valid up to 12 months prior to signing the informed consent form.
. Subjects shall preferably be monosensitised to the study allergens. In case of subjects sensitised to other aeroallergens, only those with the following characteristics may be included in the study (results will be valid up to 12 months prior to signing the informed consent form):
. Subjects with negative skin prick test to mold. In case specific IgE determination have been performed, the result must be \<0.35 kU/L.
Exclusion criteria
. Subjects polysensitized to other aeroallergens with clinically relevant symptoms.
. Subjects who have received previous immunotherapy in the preceding 5 years to any of the tested allergens or a cross-reactive allergen or are currently receiving immunotherapy with any allergen.
. Patients in whom immunotherapy may be subject to an absolute general contraindication according to the criteria of the Immunotherapy Committee of the Spanish Society of Allergy and Clinical Immunology and the European Allergy and Clinical Immunology Immunotherapy Subcommittee may not be included.
. Subjects with uncontrolled severe asthma, and/or with FEV1 \<80% of baseline despite adequate pharmacological treatment by the time of the enrolment.
. Subjects on treatment with ß-blockers.
. Subjects on treatment with immunosuppressive or biological drugs.
. Subjects who are unstable by the time of enrolment (respiratory infection, febrile process, acute pruritus, etc.).
. Subjects with chronic urticaria during the last 2 years, severe anaphylaxis or with hereditary angioedema history.
