VVN432 nasal spray safety and early testing in healthy adults and people with chronic rhinosinusitis

A Phase I Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of VVN432 Nasal Spray in Healthy Chinese Adult Subjects and Patients With Chronic Rhinosinusitis.

Phase 1 Interventional VivaVision Biotech, Inc · NCT07259538

This will test whether VVN432 nasal spray is safe and how the body processes it in healthy adults and in people with chronic rhinosinusitis.

What this trial studies

The program has two parts: a single-ascending-dose (Phase 1a) single-center, randomized, double-masked, vehicle-controlled stage in healthy adults to characterize safety, tolerability, and pharmacokinetics, and a multiple-ascending-dose (Phase 1b) multi-center, randomized, double-masked, vehicle-controlled stage in patients with chronic rhinosinusitis to evaluate safety, tolerability, PK/PD, and preliminary efficacy. Participants will receive either 0.5% or 1% VVN432 nasal spray or vehicle control and undergo serial safety and PK sampling. CRS patients will also be assessed with nasal endoscopy and CT-based scores and symptom measures to detect early signs of efficacy. The study focuses on short-term tolerability and how the drug is absorbed and processed when delivered intranasally.

Who should consider this trial

Good fit: Ideal candidates are adults 18–55 years old with a confirmed diagnosis of chronic rhinosinusitis (with or without nasal polyps), ongoing nasal symptoms for more than four weeks, and meeting the specified endoscopy and CT score thresholds.

Not a fit: People outside the required age or BMI ranges, those with known hypersensitivity to the study drug, or those who do not meet the required endoscopy or CT criteria are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, VVN432 could become a new topical nasal option that reduces CRS symptoms while limiting systemic exposure compared with oral treatments.

How similar studies have performed: Intranasal therapies such as steroid sprays have proven benefit for CRS, but VVN432 is a novel compound and this Phase 1 program is early-stage and unproven.
