Study Summary

This trial will study the effects of a new drug, OPN-375, on adolescents with nasal polyps. The trial will last for 20 weeks, and will compare the new drug to a placebo. A total of 120 adolescents will be enrolled in the study.

Who is the study for?
Adolescents aged 12-17 with bilateral nasal polyps can join this trial. They must use effective birth control if sexually active, be able to use the study's inhaler correctly, and have mild symptoms of nasal congestion. Those with stable asthma may participate but must stop certain medications.Check my eligibility
What is being tested?
The trial is testing OPN-375 (186 μg twice daily) against a placebo over 16 weeks, followed by a 12-week open-label phase. It's for adolescents with nasal polyps and involves about 120 participants who are randomly assigned in a 2:1 ratio to either the drug or placebo.See study design
What are the potential side effects?
While specific side effects of OPN-375 aren't listed here, similar treatments often cause nosebleeds, headaches, irritation at the application site, and potential growth rate reduction in adolescents due to steroid exposure.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Would I be eligible to enroll in this research project?

"This clinical trial is for children aged 12-17 who have nasal polyps. Around 120 participants will be accepted into the trial."

Answered by AI

Does this trial take into account patients that are geriatric?

"This study is only enrolling adolescents aged 12-17 years old."

Answered by AI

What are researchers hoping to achieve with this clinical trial?

"The main outcome of this study, assessed over a 4-week period, is the mean change in total polyp grade from baseline at Week 16. Secondary outcomes include changes in diary symptom scores for symptoms of nasal congestion/obstruction, measured as instantaneous and reflective scores for the morning and afternoon (AM and PM scores); this is graded on a scale of 0 (no symptom) to 3 (severe symptom); changes in bilateral polyp grade over time, graded on a nasal polyp grading scale score of 0 to 6 points per nostril, with 0 (no polyps) to 3 (severe polyps) points; and"

Answered by AI

Has the FDA cleared OPN-375 for use at the 186 μg BID dosage?

"OPN-375 186 μg BID received a safety score of 3 because this is a Phase 3 trial. This means that while there is some data supporting efficacy, there is also extensive data supporting safety from multiple rounds of testing."

Answered by AI

Can people with this illness participate in the research at this time?

"Yes, the latest information from clinicaltrials.gov reveals that this trial is still recruiting patients. The posting date was December 31st, 2018, and the study is enrolling 120 people at 29 different sites."
