LYR-220 for Adult Subjects With Chronic Rhinosinusitis (BEACON Study)

BEACON: A Phase II, Patient-blinded, Two-part, Randomized, Parallel-group Trial to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of LYR-220 in Chronic Rhinosinusitis (CRS) Patients Who Have Had a Prior Ethmoidectomy

This study will assess the safety, tolerability, pharmacokinetics and efficacy of two LYR-220 designs in symptomatic adult chronic rhinosinusitis (CRS) subjects who have had a prior functional endoscopic sinus surgery.

This is a Phase II, Patient-blinded, Two-part, Randomized, Parallel-group Trial to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of LYR-220. The study will consist of two parts: Part 1 will enroll up to 10 patients and is open label. Part 2 is randomized, sham controlled and will enroll approximately 40 patients. The study follow-up duration is 28 weeks.
