Outcome Measures
Primary Outcome Measures

Change from baseline to the end of Week 4 in average total instantaneous AM scores (evaluation of symptom severity immediately preceding the time of scoring) for each symptom: nasal congestion, nasal discharge (anterior and/or posterior), facial pain/pressure sensation. Baseline scores are the averaged total instantaneous AM scores over the last 7 days of the single blind run in period, and the end of Week 4, scores are averaged over the 7 days from the subject diary. Range of scores for each nasal symptom is 0= none, 1 = mild, 2 = moderate, 3 = severe. Composite score is a sum of the 3 symptom scores and will range from 0 to 9.

- Change from baseline to defined timepoints - subject symptoms and functioning as measured by the Sinonasal Outcome Test - 22-item (SNOT-22) total score and sub domains [24 Weeks]
The SNOT-22 is a subject-completed questionnaire that consists of 22 symptoms and social/emotional consequences of their nasal disorder across several domains including: rhinologic, ear/facial pain, psychological dysfunction, and sleep dysfunction. Each item is rated as follows: 0=no problem, 1=very mild problem, 2=mild or slight problem, 3=moderate problem, 4=severe problem, 5=problem as bad as it can be.
- Change in baseline to Week 24/ET as measured by the Euroqol 5-dimension (EQ-5D) instrument [24 Weeks]
The EQ-5D consists of the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The subject is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the 5 dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the 5 dimensions can be combined into a 5-digit number that describes the subject's health state. Scores for health state range from 0 to 1. The EQ VAS records the subject's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS can be used as a quantitative measure of health outcome that reflect the subject's own judgement. VAS scores range from 0 to 100.
- Change in baseline to Week 24/ET as measured by the Short-Form 36 health survey, version 2 (SF-36v2) [24 Weeks]
The SF-36v2 is a multipurpose, 36-item subject-completed validated questionnaire that measures 8 domains of health: physical functioning, role limitations due to physical health (RP), bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health. The SF-36v2 survey with a 4-week recall will be used. It yields scale scores for each of these 8 health domains , each of which is scored from 0 to 100.
- Change in baseline to Week 24/ET as measured by the Short-Form 6-Dimension (SF-6D) Instrument [24 Weeks]
The SF-6D is a single health state index derived from the 11 items from the SF-36v2. SF-6D scores range from 0.291 to 1
- Change in sleep quality as measured by the Pittsburgh Sleep Quality Index (PSQI) [24 Weeks]
The PSQI is a validated, self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. Nineteen individual items generate 7 "component" scores (each ranging between 0 and 3): subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The sum of scores for these 7 components yields 1 global score ranging between 0 and 21.
- Change in depressive symptoms from baseline to Week 24/ET as measured by change in the severity of depression as measured by the Quick Inventory of Depression Symptomatology (QIDS) [24 Weeks]
The 16-item QIDS (Rush et al. 2003) is designed to assess the severity of depressive symptoms. The QIDS is available in a self-rated version and assesses all the criterion symptom domains designated by the American Psychiatry Association Diagnostic and Statistical Manual of Mental Disorders - 5th edition to diagnose a major depressive episode. The 7-day period prior to assessment is the usual time frame for assessing symptom severity. Scores range from 0 to 27.
- Change in olfactory impairment from baseline to Week 24/ET as measured by the Smell Identification Test (SIT)™ [24 Weeks]
The SIT is a test comprised of 4 booklets each containing 10 microencapsulated (scratch and sniff) odors. Forced choice response alternatives accompany each test item. The test provides an absolute indication of smell loss (anosmia; mild, moderate or severe hyposomia) as well as an index to detect malingering.
- Change in overall health from baseline to Week 24/ET as measured by the percent of subjects improved as indicated by the Patient Global Impression of Change (PGIC) at Week 24/ET [Week 4, Week 24]
Global impression of change will be assessed using a subject-completed PGIC scale range: 1 - Very much improved, 2 - Much improved, 3 - Minimally improved, 4 - No change, 5 - Minimally worse, 6 - Much worse, 7 - Very much worse
- Change in work productivity from baseline to Week 24/ET as measured by the Health and Work Performance Questionnaire (HPQ). [24 Weeks]
The Health and Work Performance Questionnaire measures work productivity (absenteeism and presenteeism). - Absenteeism is measured in missed work days over the past four weeks (range 0-20); absenteeism is measured in % productivity at work (0-100%), with higher values indicating improved productivity. - Presenteeism can be converted to number of days of productive time lost per month, and when added to the number of lost days due to absenteeism provides an estimate of total productive work days lost.
