Chronic Rhinosinusitis (CRS)

Summary

The goal of this clinical study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of VVN432 Nasal Spray in healthy volunteers (Phase Ia) and in patients with chronic rhinosinusitis (Phase 1b). This study consists of two parts (Phase 1a and Phase 1b): Phase 1a (SAD) is a single-center, randomized, double-masked, vehicle-controlled study to assess the safety, tolerability, and PK of VVN432 Nasal Spray in healthy adult subjects. Phase 1b (MAD) is a multi-center, randomized, double-masked, vehicle-controlled study to assess the safety, tolerability, PK/PD, and preliminary efficacy of VVN432 Nasal Spray in patients with chronic rhinosinusitis.
