General information about the trial
|
|||
Main objective of the trial |
The aim of the study is to assess the sensory quality of the nasic neo nasal spray compared to a comparative preparation with the same active ingredient composition.
It is assumed that the modified galenics due to the addition of hyaluronic acid improves the sensory quality of the nasal spray.
|
||
Protection of trial subjects |
Physical examinations were carried out at screening visit. Only patients presented normal physical examination were included into the study. During the course of study for all patients the use of non-steroidal analgesics was allowed.
Patients had the right to withdraw from the trial at any time and this irrespective of the reason.

Recruitment
|
|||||||||||||||||||
Recruitment details |
After the patients have undergone surgery on the nasal mucosa by medical members of the study group, they were informed about the study and were given the Patient Information Form. After having given written informed consent, the patients were examined for suitability according to the inclusion and exclusion criteria. | ||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||
Screening details |
Subjects were eligible for inclusion, if the main criteria were met: - post-operative nasal breathing disabilities after surgery on the nasal septum or the nasal conchae - surgical intervention must have taken place at least one week prior to enrolment - signed and dated Informed Consent | ||||||||||||||||||

Notes [1] - The number of subjects reported to be in the baseline period is not equal to the worldwide number of subjects enrolled in the trial. It is expected that these numbers will be the same. Justification: For the comparison of the inter- and intra-group changes in the sensory evaluation, the baseline values at V1 and V3 were assessed. This applies to Treatment Sequence 1 and also to Treatment Sequence 2, resulting overall in 51 subjects who attended the baseline period. |

End point description |
The primary endpoint of the study was the difference in the total-score of the sensory-assessments from the Nasal-Spray-Sensoric-Scale (14 items) between IMP and the comparative preparation after first application.
The differences between the 2 nasal sprays were analysed independently of each other in the cross-over design in the assessments at V1 und V3 at the respective first application of the nasal sprays (inter-group-differences).
