Noninterventional Study on Tolerability and Safety of One Strength Updosing With Novo-Helisen Depot House Dust Mites (NOVUS-UP)

July 24, 2025 updated by: Allergopharma GmbH & Co. KG

NOVo-Helisen Depot HoUSe Dust Mites - A Prospective, Multicenter, Noninterventional Clinical Study on the Tolerability and Safety of Short One Strength UP-dosing in Children, Adolescents, and Adults in Daily Practice

The goal of this non-interventional study is to investigate the safety and tolerability of a new simplified up-dosing schedule for Novo-Helisen Depot.

Novo-Helisen Depot is an approved allergen immunotherapy used to treat allergies to house dust mites. For allergen immunotherapy, it is important that the allergen dose is gradually increased, a process known as up-dosing to induce immune tolerance to the allergen. The recently approved One Strength up-dosing scheme for Novo-Helisen Depot allows up-dosing with 6 injections instead of the previously required 14 injections.

The main questions the study aims to answer are:

How is the tolerability and the safety of One Strength up-dosing scheme in daily practice? This study includes approximately 105 patients (children (≥5 years), adolescents, and adults), receiving this treatment as part of their usual care.

Study data on safety and tolerability wil be collected for each patient during the first 8 injection visits.

The study will be conducted at 6-8 study sites in Poland.

Study Overview

Detailed Description

The Standard dose escalation scheme with the unmodified (native) SCIT house dust mite preparation Novo-Helisen Depot consists of 14 injections.

The newly approved One Strength dose escalation scheme, recently approved for children (≥5 years), adolescents (12-17 years) and adults (≥18 years), offers a simplified dose escalation scheme with only 6 injections. To date, the safety and tolerability of this One Strength escalation scheme has been demonstrated in 2 clinical trials involving 243 patients (aged 5-65 years). The objective of the present non-interventional study is to compare the safety and tolerability of the One Strength dose escalation scheme (6 injections) in different age groups (children, adolescents, adults) and to supplement available clinical trial data on safety and tolerability with clinical study data in daily practice.

Data collection during the first 8 visits of treatment with NHD (D.p./D.f.) using the One Strength dose escalation scheme:

Visit 1: Informed consent, In-/Exclusion-criteria, demographics, medical history, first injection (dose escalation)

Visits 2-6: 2nd to 6th injection (dose escalation)

Visits 7-8: 7th and 8th injection (maintenance doses)

In line with the SmPC recommendations, all patients must be monitored for at least 30 minutes after each injection and then be examined by the physician. Individually, this observation time may be prolonged.

Study Population

This NIS will enroll a total of 105 patients, including 35 children (aged ≥5 to < 12 years), 35 adolescents (aged ≥12 to <18 years), and 35 adults (aged ≥ 18 years).

Patient recruitment will be conducted at six to eight allergy-specialized study sites across Poland.

Participation in this NIS follows the independent and prior decision by the treating physician and the patient to begin therapy with the One Strength dose escalation scheme of NHD (D.p./D.f.). The indication and use of the One Strength up-dosing scheme of NHD (D.p./D.f.) is based exclusively on the individual therapeutic need.

Description

Inclusion Criteria:

  • Written informed consent from the patient. For patients under the age of 18, the consent of both parents/legal guardians is also required.
  • Patients who are eligible for treatment with the One Strength dose escalation scheme of NHD (D.p./D.f.) according to the specifications in the SmPC. These include children (5 to <12 years), adolescents (≥12 to <18 years) and adults (≥18 years) with allergic (IgE-mediated) diseases, such as allergic rhinitis, allergic conjunctivitis, allergic bronchial asthma (see section 4 of the current SmPC)
  • The treatment decision must precede the decision to participate in the study and must be independent.

Exclusion Criteria:

  • Any contraindication according to section 4.3 of the current SmPC for NHD (D.p./D.f.) for the One Strength dose escalation scheme.
