简要总结
This is a 16-Week Randomized, Double-Blind, Placebo Controlled, Parallel-Group, Multicenter Study Evaluating the Efficacy and Safety of OPN-375 186 μg Twice a Day (BID) in Adolescents with Bilateral Nasal Polyps followed by a 12-Week Open-Label Treatment Phase. The total planned number of subjects is approximately 72 adolescents (12-17 years of age) who will be randomly assigned to receive 1 of 2 study treatments using a 2:1 ratio (OPN-375 186 μg: Placebo). For the PK sub-study, up to 14 subjects will be enrolled to obtain 10 completers.
详细描述
The primary objective of this study is to evaluate the efficacy of intranasal administration of OPN-375 186 μg Twice a Day (BID) versus placebo in adolescents with bilateral nasal polyposis and nasal congestion by analyzing the reduction of nasal congestion/obstruction symptoms at the end of Week 4 measured by the 7-day average instantaneous morning diary symptom scores and the reduction in total polyp grade at Week 16 as determined by a nasal polyp grading scale score measured using a 0 to 6 point severity grading scale.

入排标准
入选标准
- •Male or female subjects aged 12 to 17 years, inclusive, at time of Visit 1 (Screening).
- •Female subjects, if sexually active, must,
- •be practicing an effective method of birth control (e.g., prescription oral contraceptives, contraceptive injections, contraceptive patch, intrauterine device, double-barrier method \[e.g., condoms, diaphragm, or cervical cap with spermicidal foam, cream, or gel\], or male partner sterilization) before entry and throughout the study, or
- •be surgically sterile (have had a hysterectomy or bilateral oophorectomy, tubal ligation, or otherwise be incapable of pregnancy), or
- •be abstinent.
- •All female subjects not documented to be infertile (e.g., infertility due to congenital abnormality or surgical sterilization) must have a negative serum or urine beta-human chorionic gonadotropin (hCG) at Visit 1 (Screening) and a negative urine pregnancy test at the Visit 2 (Day 1/Randomization/Baseline).
- •Must have bilateral nasal polyposis with a grade of 1 to 3 in each of the nasal cavities as determined by a nasal polyp grading scale score measured by nasoendoscopy at Visit 1 (Screening).
- •Must report at least mild symptoms of nasal congestion/obstruction as demonstrated by an average morning nasal congestion/obstruction score of at least 1.0 over a 7 day period during the single-blind run-in period. (Subjects not meeting this inclusion criterion may be re-screened once after at least 4 weeks.)
- •Subjects with comorbid asthma must be stable, defined as no exacerbations (e.g., no emergency room visits, hospitalization, or oral or parenteral steroid use) within the 3 months before Visit 1 (Screening). Subjects who received inhaled corticosteroids are required to be on no more than a moderate dosage regimen as defined by 2015 Global Initiative for Asthma Guidelines (GINA) for 1 month before Visit 1 (Screening) and to be expected to remain on it throughout the study (GINA 2015). Subjects receiving inhaled fluticasone alone or in combination may not participate in the PK sub-study.
- •Must be able to cease treatment with intranasal medications including, but not limited to, intranasal oxymetazoline or any other decongestants, intranasal antihistamines, intranasal steroids, intranasal sodium cromolyn, nasal atropine, nasal ipratropium bromide, inhaled corticosteroids (except permitted doses listed above for asthma) at Visit 1 (Screening). \[Note: intranasal antibiotics and saline are permissible\]
排除标准
- •Pregnancy or lactation
- •Has a history of cystic fibrosis
- •Have used XHANCE (fluticasone propionate) nasal spray within the past 2 months
- •Inability to achieve bilateral nasal airflow for any reason, including nasal septum deviation
- •Inability to examine both nasal cavities for any reason, including severe nasal septum deviation
- •Have known history of nasal septum erosion, ulceration or perforation, or evidence of such lesion on Visit 1 (Screening) nasal examination/nasoendoscopy
- •Other significant nasal pathology or abnormal anatomy
- •Has had any episode of epistaxis with frank bleeding in the 3 months before Visit 1 (Screening)
- •History of more than 5 sinus or nasal surgeries for either nasal polyps or nasal/sinus inflammation (lifetime)
- •Have had any surgery on the nasal septum

结局指标
主要结局
Mean change from baseline at Week 16 in total polyp grade
时间窗: 16 Weeks
Change in total polyp grade (sum of scores from both nasal cavities) at Week 16 as determined by a nasal polyp grading scale score measured using a 0 to 6 point severity grading scale, with 0 (no polyps) to 3 (severe polyps) points per nostril
Change in nasal congestion/obstruction symptoms (mild, moderate, severe) at the end of Week 4
时间窗: 4 Weeks
Change in nasal congestion/obstruction symptoms at the end of Week 4 measured by the 7-day average instantaneous morning (AM) diary symptom scores (ADS7-IA). The nasal symptom scale is what is used to score the nasal congestion/obstruction score, which is recorded in the diary. Nasal symptom scale is graded on a scale of 0=no symptom, 1=mild symptom, 2=moderate symptom, 3=severe symptom.
次要结局
- Percentage of subjects with a ≥1 point improvement in polyp grade(16 Weeks)
- Percentage of subject with a grade of 0 on at least one side of the nose(16 Weeks)
- Change in diary symptom scores for the sense of smell, measured as instantaneous and reflective scores for the morning and the afternoon (AM and PM scores)(16 Weeks)
- Subjects will assess their global impression of change since starting the study drug using the PGIC scale(16 Weeks)
- Subjects will assess their change in quality of life since starting the study drug using the quality of life questionnaire (SN-5).(16 Weeks)
- Change in bilateral polyp grade over time(16 Weeks)
- Change in diary symptom scores for the symptoms of rhinorrhea, measured as instantaneous and reflective scores for the morning and the afternoon (AM and PM scores)(16 Weeks)
- Change in diary symptom scores for the symptoms of facial pain or pressure, measured as instantaneous and reflective scores for the morning and the afternoon (AM and PM scores)(16 Weeks)
- Change in diary symptom scores for the symptoms of nasal congestion/obstruction, measured as instantaneous and reflective scores for the morning and the afternoon (AM and PM scores)(16 Weeks)
- The proportions of subjects who have reductions in the AM and PM, instantaneous and reflective, average nasal congestion/obstruction symptom scores by 0.5 or more points from baseline to the end of the double-blind treatment phase(16 Weeks)
- Proportion of subjects eligible for surgical intervention (independent of actual surgery performed)(Visit 1 (Screening) and Visit 6 (Week 16/ End of Double-Blind/Early Termination))
