Brief Title  ICMJE Demonstration of Equivalence and Early Onset of a Novel Anti-allergic Nasal Spray Compared to Marketed Nasal Spray
Official Title  ICMJE Demonstration of Therapeutic Equivalence/Non-inferiority as Well as Early Onset of Action of the Novel Water-soluble Budesonide Nasal Spray (Budesolv 10) Compared With Marketed Rhinocort® Aqua 64 in Patients Suffering From Grass Pollen Induced Allergic Rhinitis
Brief Summary

Intranasal corticosteroids are accepted as safe and effective first-line therapy for allergic rhinitis, especially in treatment of persistent symptoms.

Budesonide, a non-halogenic glucocorticoid, is widely used in the management of inflammatory mucosal diseases like chronic obstructive pulmonary disease, asthma and allergic rhinitis. It is a highly fat-soluble substance with low water solubility and is presented as dispersion in marketed nasal sprays, like Rhinocort aqua 64. The maximum therapeutic efficacy of Rhinocort aqua is obtained after an application period of 7 to 14 days. In Budesolv, the solubility of budesonide is considerably increased suggesting that the same therapeutic efficacy can be reached with a lower dose. Better bioavailability of the dissolved drug promise an earlier onset of therapeutic efficacy. The current trial is undertaken to demonstrate these two effects. Subjects suffering from grass pollen allergic rhinitis will be challenged with grass pollen in a challenge chamber.

Allergic subjects will be treated with two actuations (50 μl) of respective study treatment into each nostril once daily for 8 days. The total daily budesonide dose will be 40 μg per subject for Budesolv 10 and 256 μg per subject for Rhinocort® aqua 64. The primary objective of the study is to show non-inferiority of Budesolv 10 to Rhinocort® aqua 64. On day 8 grass pollen allergic patients will be challenged with grass pollen over a period of 6 hours and subjective nasal symptoms (congestion, sneezing, itching, rhinorrhea) as well as objective symptoms (nasal airflow, nasal secretion) will be assessed every 15 minutes.

The second objective of the trial is to demonstrate an early on-set of therapeutic efficacy of Budesolv 10 compared to Rhinocort aqua. On day 1, grass pollen allergic patients will be challenged with grass pollen allergen in the challenge chamber over a period of 6 hours. After 1 hour 45 minutes, patients will receive their first dosage of the respective nasal spray treatment. During the 6 hour grass pollen challenge, subjective and objective endpoints will be measured every 15 minutes.

To eliminate an individual bias based on expectations, the effect and onset of action is also compared to the effects of a suitable placebo. The same set of study participants will receive all three interventions in three consecutive treatment periods.

Detailed Description

This is a randomized, placebo controlled, three way cross over, double-blind, single site trial in adult subjects (18 years of age and older) who demonstrate grass specific Immunglobulin E (IgE) reactivity and have a history of grass pollen induced allergic rhinitis/rhinoconjunctivitis with or without controlled asthma. In the cross-over setting three treatments, namely placebo, Budesolv 10 or Rhinocort® aqua 64 will be evaluated.

The primary objective of the trial is to demonstrate therapeutic equivalence/non-inferiority between Budesolv 10 and Rhinocort® aqua 64, a marketed comparator containing the same compound (budesonide), in patients suffering from grass pollen induced allergic rhinitis/rhinoconjunctivitis with or without controlled asthma on day 8 of treatment. A placebo group will be introduced to show effectiveness of treatment and hence validate the trial design.

The evaluation will be based on the assessment of rhinitis symptoms during grass pollen challenge performed in the Vienna Challenge Chamber (environmental exposure chamber).

Secondary objective of the trial is the early onset of action of Budesolv 10 compared to Rhinocort® aqua 64, determined on day one of treatment.

Visit 1 + 2 - Screening + Inclusion period:

Subjects will be screened for appropriate allergic response. A total nasal symptom score (TNSS) of at least 6 points out of 12 within the first two hours in the grass pollen challenge chamber is required to be included into the study.

Visit 3 + 5 + 7 / "day 1":

Eligible subjects will be randomly assigned to one of the three treatment arms (fully blinded) in the order of their screening numbers assigned at visit 1. Subjects will enter the study site about one hour ahead of the start of allergen provocation. After positive completion of all study relevant assessments, subjects enter the grass pollen challenge chamber for subjective and objective assessments for a period of 6 hours. One hour forty-five minutes after entry, the first treatment will be applied.

The subjective nasal symptom score will be recorded every fifteen minutes during a 6-hour allergen exposure challenge. Every hour rhinomanometry will be performed to objectively evaluate the respiratory function of the nose. Additional rhinomanometry will be performed at two hours 30 minutes after entry. Subjects will continue treatment with two actuations into each nostril once a day until day 7.

Visit 4 + 6 + 8 / "day 8":

On day 8 of their respective treatment block, subjects will enter the study site about two hours before provocation will start. Subjects will take their last treatment dosage approximately one hour before entering the challenge chamber. The study medication device will be returned to study site staff for external analytical evaluations after usage (in-use-stability test). After receiving their last treatment dose and shortly before entering the challenge chamber, baseline symptom score will be assessed. Like on day one, subjects will be provoked for 6 hours with grass pollen allergens. Subjective symptom scores will be recorded every fifteen minutes, and rhinomanometry will be performed every hour during the challenge.

Between the respective study treatments, a wash-out period of at least 20 days must be adhered to allowing complete dissipation of the previous treatment. After the wash-out period, subjects change to the next treatment block in the sequence. During the entire trial, subjects will be asked to monitor for adverse events (AEs), and they will record the use of concomitant medications on the provided form. Female subjects of child-bearing potential will complete a urine pregnancy test in the course of all visits.

Following parameters will be assessed:

  • Subjective symptom score (nasal, ocular, respiratory) during a grass pollen challenge lasting for 6 hours - every 15 minutes Active anterior rhinomanometry (AAR) - every 60 minutes, additional measurement on day 1 at 2:30 after entry.
  • Lung function tests using regular spirometry for FEV1 and FVC - every 120 minutes
  • Nasal secretion weight - every 30 minutes
  • Physical examination - at Screening and Follow up
  • Vital signs - every visit, pre- and post-challenge
  • Safety laboratory assessments: Complete blood count with differential, blood chemistry, liver function, urine dipstick test - at screening and last treatment visit, serology at screening and drug abuse test on investigator's decision
  • Skin Prick Test with skin prick test solution (Manufacturer Allergopharma) - at Screening or within the previous 6 months
  • Specific CAP analysis (g6) - at Screening or within the previous 6 months
  • ECG - at screening and Follow up
  • Adverse events - throughout the study
  • Concomitant medication - throughout the study One week after the final provocation session, subjects will complete the trial after their follow up visit. Validated methods of data collection, analysis, and evaluation will be used for the trial.

The trial endpoints are listed below:

Primary efficacy endpoint:

The primary efficacy endpoint will be the mean 'Total Nasal Symptom Score' (TNSS), calculated as the baseline adjusted mean of TNSS measured at 17 time points (every 15 minutes) during the grass pollen allergen exposure challenge from time point 2 to 6 hours on day 8.

The TNSS is the sum of the symptoms "nasal congestion", "rhinorrhea", "itchy nose" and "sneezing". Each individual symptom will be scored on a 4-point categorical scale from 0-3 (where "0"= none "1"=mild "2"=moderate "3"=severe).

Key Secondary efficacy endpoint:

Time point when onset of action can be observed.

Additional secondary efficacy endpoints:

  • Nasal airflow: will be assessed every hour during the six hour grass pollen allergen exposure challenge
  • Nasal secretion: will be assessed every 30 minutes during the six-hour grass pollen allergen exposure challenge. Additional rhinomanometry will be done on day 1 at 2:30 h after entry in the challenge chamber
  • Total ocular symptom score (TOSS) is the sum of the symptoms "ocular itching", "redness", "watery eyes".
  • Total asthma symptom score (TASS) is the sum of the symptoms "cough", "wheeze", "dyspnea".

Each individual symptom of TOSS and TASS will be scored on a 4-point categorical scale from 0-3 (where "0"= none "1"=mild "2"=moderate "3"=severe). TOSS and TASS will be assessed every 15 minutes during the six-hour grass pollen allergen exposure challenge.

Safety endpoints:

  • Adverse events (AEs)
  • Safety laboratory
  • ECG
  • Spirometry (FeV1, FVC)
