Treatment Study for Adolescents with Bilateral Nasal Polyps

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.

In order to participate you must meet the following criteria:

• Are male or female, 12 to 17 years of age, 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 agree to abstinence.
• 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 (β-hCG) at Visit 1 (Screening) and a negative urine pregnancy test at the Visit 2 (Day 1/Randomization/Baseline).
• 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).
