•Able to sign and date the informed consent/assent form prior to any trial-specific procedure. Patients may check a box on the assent form if they are unable to provide a signature. (Parents and/or authorised legal representative(s) will have to give written informed consent for minors in their custody.), Covered by a health insurance system as per local regulation., Demographics and Medical History - Aged =5 to =17 years old at the randomisation visit., Documented, physician diagnosed, clinically relevant history of moderate to severe ARC induced by birch pollen (with or without asthma) despite having received treatment with symptom-relieving medication during at least 1 previous birch pollen season for ages 4 through 6 or at least 2 previous birch pollen seasons for ages 7 through 17 years at screening., A Retrospective ARC Total Symptom Score (TSS), based on the previous birch pollen season of at least 12 out of a maximum possible score of 18 AND a retrospective score of at least 30 on a general VAS 0-100 on the severity of symptoms as evaluated by the patient or by the parent/authorised legal representative if the patient is not able to perform the assessment, at screening. Retrospective ARC TSS (TSS0-18) is rated the same way as Daily Symptom Score (DSS) (DSS0-18)., Screening Tests and Evaluations - Positive Skin Prick Test (SPT) to Betula pendula at screening visit. The SPT is considered positive if it results in a wheal diameter = 3.0 mm [with positive control (histamine) = 3.0 mm and negative control = 0 mm]). The Sponsor will accept to include patients who have a documented positive SPT in their medical records if this SPT was performed during the previous 6 months preceding the screening visit at the same investigational site in which they are enrolled., Positive specific Immunoglobulin E (IgE) to pollen allergens of Betula pendula and Bet v 1 at screening (CAP-RAST birch pollen allergens and Bet v 1 specific IgEs = 0.7 kU/L)., Negative urine pregnancy test on all female patients of childbearing potential or who have had their first menarche prior to randomisation., Lifestyle Considerations - Internet access at home or via a portable device so that patients or the parent/authorised legal representative can complete the e-Diary in a dedicated application on a mobile phone daily via internet. Patients will start scoring at randomisation, i.e., 4 months before the pollen season.

•Medical History - Any clinical deterioration of asthma (i.e., asthma exacerbation) that resulted in emergency procedure/treatment or treatment with systemic corticosteroids within 3 months prior to randomisation., Screening Tests and Evaluations. A documented clinically relevant history of seasonal ARC symptoms caused by an allergen source, other than tree pollen from the birch homologous group, with a season overlapping the BPS., A documented clinically relevant history of perennial ARC symptoms caused by an allergen source such as animal dander to which the patient is exposed during the BPS., Any significant abnormal laboratory parameter or alteration in vital signs that could increase the risk for the patient, in the opinion of the Investigator., Medication - Ongoing treatment with prohibited treatment as listed in Section 8.2.3 or any allergen immunotherapy product including Specific Immunotherapy (SIT) or past full courses of SIT against birch pollen terminated for less than 5 years or past courses of SIT for other allergens terminated for less than 6 months prior to start of randomisation., Patients requiring continuous treatment with systemic corticosteroids for any indications., Patients requiring continuous treatment with ß-blockers or with Monoamine Oxidase Inhibitors (MAOIs)., Treatment with an immunosuppressive (ATC code L04 or L01) within 3 months prior to the screening visit., Hypersensitivity to any excipient of the IMP/placebo, or contraindication to the use of RMs (i.e., antihistamine and nasal corticosteroids)., Patients following a strict low sodium diet as the IMP treatment contains 590 mg of sodium chloride per vial in a 10 mL solution., Inability to adhere to the washout periods as defined by the protocol, with respect to screening and to refrain from using the medications indicated until after the trial is complete., For patients =7 years old: Reduced lung function at randomisation defined as Forced Expiratory Volume in 1 second (FEV1) < 70% of the predicted value. For patients with asthma, this is assessed on the patient's usual asthma controller medication*. The following wash-out periods apply for asneeded asthma reliever medication at least a 6-hour wash-out of Short- Acting Beta Agonists (SABAs), a 12 hour wash-out of Long-Acting Beta Agonists (LABAs) 24h wash-out for ultra-LABAs and 5 days or 5 halflives for inhaled corticosteroids. *In order to ensure that the asthmatic patients with a mild to moderate asthma status are controlled by treatment steps 1, 2 or 3 in accordance with the Global Initiative for Asthma (GINA 2022), the proper continuous asthma treatment i.e., controller is maintained. Only the asthma reliever medications must be stopped before performing spirometry. If an asthma medication is used as both controller and reliever, such as inhaled corticosteroids (in combination with formoterol [LABA]), it must not be stopped before performing spirometry., Patients who would be likely to require prohibited concomitant therapy during the trial or who are anticipated to require using of such agents during the trial. Any medication given for an AE will be permitted.For other exclusion criteria, please refer to the section 7.2 of the Protocol., Severe or uncontrolled asthma or asthma treated with asthmatic therapies consistent with steps 4 or 5 as defined by Global Initiative for Asthma (GINA) 2022 received within 12 months prior to entry in the trial. Eligible asthmatic patients will be those wit
