Trial Outcomes & Findings for A 6-Month Extension Study of OTO-104 in Meniere's Disease (NCT NCT02706730)

NCT ID: NCT02706730

Last Updated: 2022-12-14

Results Overview

Otoscopic examinations were conducted at each visit. It was considered important to understand if the tympanic perforation that resulted from the IT injection persisted at the end of study visit (Week 24 \[Month 6\]).

Participant Flow

A total of 189 subjects registered for this study and signed informed consent and were enrolled. Of the 189 subjects enrolled, 49 had previously completed the 104-201102 study and 140 had previously completed the 104 201506 study. The first subject enrolled on February 16, 2016, and the last subject completed on September 9, 2017.

This study was terminated early based on results of study 104-201506, a US Phase 3 study that indicated no statistically significant difference in the primary endpoint of reduction in definitive vertigo days (DVD) for OTO-104 vs placebo nor for any of the secondary endpoints. Decision was made to terminate all ongoing studies on August 31, 2017, including this study. At the time of termination, 156 subjects completed the study through Month 3 and 121 subjects completed the study through Month 6.

PRIMARY outcome

Timeframe: 6 Months

Population: The 6-month Safety Analysis Set included all subjects who received at least 1 dose of study drug and completed the study at the Month 6 visit.

Otoscopic examinations were conducted at each visit. It was considered important to understand if the tympanic perforation that resulted from the IT injection persisted at the end of study visit (Week 24 \[Month 6\]).
