Efficacy and Safety of SLIT in Patients With Rhinitis/RC With/Without Mild-moderate Asthma, Due to Dpt and/or Df

Recruiting now · Phase 3 · Has a placebo group

Conditions studied: Rhinitis, Rhinoconjunctivitis

In brief

The goal of this clinical trial is to learn if MM09 works to treat patients allergic to house mites, displaying rhinitis/rhinoconjunctivitis with or without mild to moderate asthma. It will also learn about the safety of MM09. The main questions it aims to answer are: Does MM09 reduce the symptoms and the need of rescue medication? What medical problems do participants have when inhaling MM09? Researchers will compare MM09 to a placebo (a look-alike substance that contains no drug) to see if MM09 works to treat rhinitis/rhinoconjunctivitis.

Who can join

Age: 12 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Participants who have signed and dated Informed Consent Form (ICF).
• Female or male aged 12 to 65 years, both included, at the time of signature of ICF.
• Participants with confirmed clinical history of inhalation allergy with intermittent or persistent moderate-severe rhinitis/ rhinoconjunctivitis according to the ARIA classification(1) of at least 1 year of duration (treated with anti-allergic medication) with or without mild-moderate controlled intermittent or persistent asthma according to the definition of GINA 2022(2) caused by Dermatophagoides pteronyssinus and/or Dermatophagoides farinae.
• Participants with positive skin prick test and a wheal major diameter ≥ 5 mm to a standardized allergen extract of Dermatophagoides pteronyssinus and/or Dermatophagoides farinae.
• Women of childbearing age (i.e., following menarche and until postmenopause, defined as no menses for 12 months without an alternative medical cause, or non-subject to permanent sterilisation methods, such as hysterectomy, bilateral salpingectomy and bilateral oophorectomy) must have a serum pregnancy test negative result, and a confirmed menstrual period before enrolling the study.
• Women of childbearing age must commit to using a highly effective contraception method during the trial and up to 1 month after the end of treatment with the investigational medicinal product (IMP). Such methods include: combined (estrogen and progestogen containing) hormonal, contraception. associated with inhibition of ovulation (oral, intravaginal or transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable or implantable), intrauterine device, intrauterine hormone-releasing system, male condom, diaphragm used with spermicide, bilateral tubal occlusion, vasectomized partner or sexual abstinence.
• Participants capable of complying with dosage regimen.
• Participants owning a smartphone to register symptoms and medication consumption.
• Participants not sensitized to any other clinically relevant allergen or sensitized with the following characteristics (sensitization to other allergens will be assessed through skin prick test in Europe and LATAM and through IgE levels in China):
• Participants sensitized to dander (with a positive skin prick test for dander or IgE ≥ 0.35 kU/L), provided that they have occasional exposure and symptoms.
• Participants sensitized to endemic pollen (with a positive skin prick test or IgE ≥0.35 kU/L) will be scheduled to be included so that the pollen season does not coincide with the Baseline Evaluation Period nor with one month before and after the Main Evaluation Period. In LATAM, grass sensitized participants will not be included.
• Participants not sensitized to moulds, cockroach, Blomia tropicalis or other geographically relevant mites (negative skin prick test or IgE < 0.7 kU/L).
• Participants with a RCSMS ≥ 3 out of 6 recorded for at least 10 days during the baseline evaluation period, corresponding to moderate-to-severe allergic rhinitis/rhinoconjunctivitis.
• Participants with specific IgE against a complete extract of D. pteronyssinus and / or D. farinae or any of the molecular components of allergenic sources with a value ≥ 3.5kU/L.

You may not qualify if…

• Participants who have received previous immunotherapy to any of the tested allergen during the last 5 years or any desensitization process in the last 2 years (e.g., oral immunotherapy [OIT], milk, or egg) before the second screening visit (S2), or currently receiving immunotherapy with any other allergen.
• Those cases in which allergen-specific immunotherapy (AIT) would be a contraindication according to the criteria of European Allergy and Clinical Immunology Immunotherapy Subcommittee.(3)
• Asthmatic participants with forced expiratory volume in the first second (FEV1) <80% (following at least a 6-hour washout of short-acting beta2 agonists [SABA] and 12-hour washout of long-acting beta2 agonists [LABA]) despite pharmacological treatment by the time of enrolment.
• Participants with uncontrolled asthma, according to GINA 2022,(2) asthma with poor symptom control (frequent symptoms or reliever use, activity limited by asthma, night waking due to asthma) and/or frequent exacerbations (≥2/year) requiring oral corticosteroids (OCS), or serious exacerbations (≥1/year) requiring hospitalization.
• Participants with severe asthma, according to GINA 2022,(2) on Step 4 or 5 treatment, who had poor symptom control and had good adherence and inhaler technique.
• Participants on treatment with β-blockers or angiotensin-converting enzyme (ACE) inhibitor.
• Participants on treatment with immunosuppressive or biological drugs.
• Participants who had not had a long enough washout/withdrawal period at the first screening visit (S1) according to criteria in the study protocol (See Table 6 in section 9.5.3) before undergoing allergen diagnostic tests (skin prick test or IgE analysis).
• Unstable participants who have suffered a respiratory tract infection and/or asthma exacerbation within 4 weeks prior to first screening visit (S1).
• Participants who have suffered chronic urticaria, severe anaphylaxis, or with hereditary angioedema history within 2 years prior to the first screening visit (S1).
• Participants having any contraindication for the use of adrenaline (e.g., hyperthyroidism, heart disease, or hypertension) according to the investigator's criteria.
• Participants with other severe diseases not related to allergic rhinitis or asthma that could interfere with the study treatment or the follow-up.
• Participants with severe and unresponsive to treatment autoimmune diseases (e.g., thyroiditis or lupus), tumoral diseases or immunodeficiencies.
• Participants that could not comply with the study protocol, according to the investigator's criteria, or have a serious mental illness.
• Participants with known allergy to any of the components of the study treatment other than study allergens.
• Participants who had a complication(s) of any nasal disease (including nasal polyp, nasal septal deviation, and hypertrophic rhinitis, drug-induced rhinitis and/or non-allergic rhinitis) affecting an appropriate evaluation of the efficacy and/or safety, according to investigator's criteria.
• Participants who had a nasal surgery within 6 months prior to the first screening visit (S1) or have programmed or anticipated nasal surgery during the trial period.
• Participants with a lesion in the oral cavity that could confound the safety profile of the study treatment, according to the investigator's criteria.
• Participants who required treatment with antihistamines and/or corticosteroids for other purposes than alleviating symptoms of allergic rhinitis (except temporal use for diseases such as common colds).
• Participants with lower respiratory tract diseases different from asthma as emphysema, bronchiectasis, or chronic obstructive pulmonary disease.
