Fudan Trans-Round Window Intracochlear Steroid Study

Academic Phase 2 study evaluating glucocorticoid delivery through the round window membrane for profound or complete sudden sensorineural hearing loss. The study compares intracochlear triamcinolone acetonide, intracochlear dexamethasone, and intratympanic dexamethasone; these arms represent one route-and-steroid comparison study rather than separate commercial programs.

Promoted as a verified institution-led Phase 2 study. ClinicalTrials.gov describes one not-yet-recruiting study of trans-round-window intracochlear glucocorticoid delivery, with triamcinolone, intracochlear dexamethasone, and intratympanic dexamethasone arms. These arms should remain collapsed and should not be presented as commercial products.
