 - with a nasal symptomatology score equal or superior to 6 at inclusion (maximal score: 12),
 
 - in case of associated bronchial asthma, will be allowed only mild intermittent asthma, not requiring systemic corticosteroids or whose use of inhaled corticosteroids has not been changed within the last month,
 - willing and able to understand and sign an approved Informed Consent Form,
 - able to understand the protocol and to attend the control visits,
 - if required by national regulation, registered with a social security or health insurance system.
 For women of child bearing potential:
 - use of an contraceptive method (oral contraceptive, intra-uterine device, tubal ligature, double barrier method: spermicide gel + condom).

| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| Efficacy: Primary criterion :
 evolution over the 14 days treatment period of the reflective (12 hours) patient-rated nasal symptom score NSS (sneezing, rhinorrhea, nose itching, nasal blockade) evaluated daily in the evening.
 
 The primary efficacy criterion is the change from baseline of the reflective patient-rated nasal symptom score (sneezing, rhinorrhea, nose itching, nasal blockade) evaluated daily in the evening, recording by the optic pens, over the 2-week treatment period.
 
 Primary analysis
 
 The primary efficacy analysis will use a likelihood-based Mixed-effects Model for Repeated Measures (MMRM) on the patient-rated reflective nasal symptom score change from baseline to week 2 (D14) and will be performed on the FAS with observed case (OC) approach. The model will include Treatment, Centre and Visits as main effects, baseline reflective NSS score as covariate.
