History or current diagnosis of the presence (in either eye) of a sub-capsular cataract 19. Any serious or unstable concurrent disease, psychiatric disorder, or any significant condition that, in the opinion of the investigator could confound the results of the study or could interfere with the subject's participation or compliance in the study 20. Recent (within 1 year of Visit 1 (Day 1/Baseline)) history of drug or alcohol abuse, or dependence that, in the opinion of the investigator could interfere with the subject's participation or compliance in the study 21.

Primary | Change From Visit 1 at End of Study in Bilateral Nasal Polyp Grade Using Endoscopic Video | : Polyp grading of each nasal cavity was determined by a nasal polyp grading scale score measured by nasoendoscopy. 0: No polyps Mild polyposis: polyps not reaching below the inferior border of the middle turbinate Moderate polyposis: polyps reaching below the inferior border of the middle concha, but not the inferior border of the inferior turbinate Severe polyposis large polyps reaching below the lower inferior border of the inferior turbinate |
Week 24 | |
Secondary | Assessment for Safety by Recording Adverse Events and Adverse Events of Special Interests | 24 Weeks, up to 30 days after last dose | ||
Secondary | Assessment for Safety Through Nasal Examination | Assessed in nasal examination worksheet which includes recording the presence of any epistaxis, septal erosion/perforation, ulceration/erosion of area other than septum. If present, the nostril location is also recorded, along with severity, and if there is any relation to an injury or trauma | 24 Weeks, up to 30 days after last dose | |
Secondary | Assessment for Safety From Recording Vital Sign - Blood Pressure | Includes systolic and diastolic blood pressure measurements in millimeter of mercury (mmHg) | Baseline, Week 12, Week 24 | |
Secondary | Assessment for Safety From Recording Vital Sign - Pulse | measure pulse in beats per minute (bpm) | Baseline, Week 12, Week 24 | |
Secondary | Assessment for Safety From the Collection of Information for Concomitant Medications Usage | 24 Weeks, up to 30 days after last dose | ||
Secondary | Total Polyp Grading Score (Sum of Scores From Both Nasal Cavities) | Polyp grading of each nasal cavity was determined by a nasal polyp grading scale score measured by nasoendoscopy. 0: No polyps Mild polyposis: polyps not reaching below the inferior border of the middle turbinate Moderate polyposis: polyps reaching below the inferior border of the middle concha, but not the inferior border of the inferior turbinate Severe polyposis large polyps reaching below the lower inferior border of the inferior turbinate |
Week 24 | |
Secondary | Number of Subjects With a Change of Greater Than or Equal to 1 Point in Bilateral Polyp Grade | Polyp grading of each nasal cavity was determined by a nasal polyp grading scale score measured by nasoendoscopy. 0: No polyps Mild polyposis: polyps not reaching below the inferior border of the middle turbinate Moderate polyposis: polyps reaching below the inferior border of the middle concha, but not the inferior border of the inferior turbinate Severe polyposis large polyps reaching below the lower inferior border of the inferior turbinate |
Week 24 | |
Secondary | Number of Subjects With a Polyp Grade of 0 on at Least One Side of the Nose at Each Visit | Polyp grading of each nasal cavity was determined by a nasal polyp grading scale score measured by nasoendoscopy. 0: No polyps Mild polyposis: polyps not reaching below the inferior border of the middle turbinate Moderate polyposis: polyps reaching below the inferior border of the middle concha, but not the inferior border of the inferior turbinate Severe polyposis large polyps reaching below the lower inferior border of the inferior turbinate |
Week 24 | |
Secondary | Sinonasal Outcome Test 22 (SNOT-22) Total Score | SNOT-22 is a subject-completed questionnaire that consists of 22 questions. The questions on the SNOT-22 efficacy evaluation were used to calculate a total score. 22 questions are divided among 4 subscales: Rhinologic (7 questions), Ear/Facial Symptoms (4 questions), Sleep Function (3 questions), and Psychological Issues (6 questions). Each item was rated on the 5-point scale. The total score can range from 0-110, 0 being the best and 110 being the worst. 0: No problem Very mild problem Mild or slight problem Moderate problem Severe problem Problem as bad as can be |
Week 24 | |
Secondary | Sniffin' Sticks N-butanol Test | The Sniffin' Sticks n-butanol (Extended test) are used to investigate human olfactory performance by use of odor pens. the Extended Test consists of 3 different subtests: Threshold, Discrimination and Identification. the Threshold test is used to ascertain the patient's olfactory threshold. the Discrimination test requires the patient to differentiate smells. The Identification test requires the patient to identify everyday smells by means of a card with different choices. The result of this test is expressed as the sum of the results of the 3 subtests, the so called TDI score (threshold, discrimination, identification). A score of more than 30 rates as normal, a score of 30 or less indicates hyposmia and a score of 15 and below point to functional anosmia in form of complete loss of the sense of smell or an extremely weakened smell ability. | Week 24 | |
Secondary | Number of Participants With a PGIC Score of Minimally/Much/Very Much Improved | The Patient Global Impression of Change (PGIC), is a questionnaire where the patient rates the change in their symptoms. Score range is from 1 (very much improved) to 7 (very much worse) | Week 24 |
