About

This is a 24-week, open-label, multi-center study designed to assess the efficacy and safety of OPN-375 186 μg twice a day in subjects with nasal polyps using Nasoendoscopic video. The total planned number of subjects is approximately 10, with each subject receiving OPN-375 186 μg twice a day.

Full description

The primary objective of this study is to evaluate the efficacy and safety of OPN-375 186 μg twice a day in adults with Bilateral Nasal Polyps using Nasoendoscopic video. The secondary objectives of this study are to evaluate the safety of OPN-375 via adverse event reports, vital signs, and nasal examination. In addition, to measure any change in subject symptoms and functioning from Baseline to 12 and 24 weeks during the study, using the Sinonasal Outcome Test -22 (SNOT-22), Patient's Global Impression of Change (PGIC), and measurement of nasal polyps by independent, blinded reader, and any changes throughout the study.

  • be postmenopausal (amenorrhea for at least 1 year).
  • Women of child-bearing potential must have a negative urine pregnancy test at Visit 1 (Day 1/Baseline)
  • Must have bilateral nasal polyposis with a grade of 2 or 3 in at least one side of the nasal cavity as determined by a nasal polyp grading scale score measured by nasoendoscopy at Visit 1 (Day 1/Baseline)
  • Must have a SNOT-22 score of ≥20 at Visit 1(Baseline/Day 1)
  • Must have been on an adequate dose of an intranasal corticosteroid (e.g. fluticasone propionate, fluticasone furoate, mometasone, triamcinolone, ciclosenide, budesonide, budesonide respules, beclomethasone) for at least 1 month, in the previous 3 months prior to Visit 1 (Day 1/Baseline)
  • Subjects with comorbid asthma or chronic obstructive pulmonary disease (COPD) must be stable with no exacerbations (e.g., no emergency room visits, hospitalization, or oral or parenteral steroid use) within the 3 months before the screening visit. Inhaled corticosteroid use must be limited to stable doses of no more than 1,000 μg/day of beclomethasone (or equivalent) for at least 3 months before screening with plans to continue use throughout the study
  • Must be able to cease treatment with oral steroids, intranasal steroids, inhaled corticosteroids (except permitted doses listed above for asthma and COPD) at Visit 1 (Day 1/Baseline)
  • Must demonstrate correct use of the demo EDS
  • Ability to read and speak English
  • Must be capable, in the opinion of the investigator, of providing informed consent to participate in the study. Subjects must sign an informed consent document indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study

Exclusion criteria

  • Women who are pregnant or lactating
  • Inability to have each nasal cavity examined for any reason, including nasal septum deviation
  • Have used XHANCE™ (fluticasone propionate) nasal spray within the past 2 months
  • Nasal septum perforation
  • Has had more than 1 episode of epistaxis with frank bleeding in the month before Visit 1 (Day 1/Baseline)
  • Have evidence of significant mucosal injury or ulceration (e.g. exposed cartilage) on Visit 1 (Day 1/Baseline) nasal examination/nasoendoscopy
  • History of sinus or nasal surgery within 3 months before Visit 1 (Day 1/Baseline). If >3 months subject should be fully recovered from surgery
  • Current, ongoing rhinitis medicamentosa (rebound rhinitis)
  • Have significant oral structural abnormalities, e.g., a cleft palate
  • Diagnosis of cystic fibrosis
  • History of Churg-Strauss syndrome or dyskinetic ciliary syndromes
  • Purulent nasal infection, acute sinusitis, or upper respiratory tract infection within 2 weeks before Visit 1 (Day 1/Baseline). Potential subjects presenting with any of these infections may be rescreened 4 weeks after symptom resolution
  • Planned sinonasal surgery during the period of the study
  • Allergy, hypersensitivity, or contraindication to corticosteroids, steroids, or to any excipients in OPN-375
  • Exposure to any glucocorticoid treatment with potential for systemic effects (e.g., oral, parenteral, intra-articular, or epidural steroids, high dose topical steroids) within 1 month before Visit 1 (Day 1/Baseline); except as noted in inclusion criteria for subjects with comorbid asthma or COPD
  • Have nasal candidiasis at Visit 1 (Day 1/Baseline)
  • History or current diagnosis of any form of glaucoma, ocular hypertension, or intraocular pressure elevation on any form of steroid therapy
  • History or current diagnosis of the presence (in either eye) of a sub-capsular cataract
  • 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
  • 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
  • Have participated in an investigational drug clinical trial within 30 days of Visit 1 (Day 1/Baseline)
  • Employees of the investigator or study center, with direct involvement in the proposed study or other studies under the direction of that investigator or study center, as well as family members of the employees or the investigator
