Trial Outcomes & Findings for LATERA-OFFICE Study (NCT NCT02964312)

NCT ID: NCT02964312

Last Updated: 2020-09-03

Results Overview

A responder is defined as a participant who has an improvement of at least 1 NOSE class or a NOSE score reduction of at least 20% compared with baseline. NOSE scores can range from 0 to 100 with higher scores indicating worse symptoms. Classes are mild (5-25), moderate (30-50), severe (55-75) and extreme (80-100).

PRIMARY outcome

Timeframe: 6 months

Population: All participants who had placement of 1 or more Latera implants and had a 6-month NOSE score.

A responder is defined as a participant who has an improvement of at least 1 NOSE class or a NOSE score reduction of at least 20% compared with baseline. NOSE scores can range from 0 to 100 with higher scores indicating worse symptoms. Classes are mild (5-25), moderate (30-50), severe (55-75) and extreme (80-100).

SECONDARY outcome

Timeframe: 1, 3, 6, 12, 18, and 24 months post procedure

Population: All participants with VAS scores at the applicable visit.

Change from baseline in the nasal obstryction VAS score. Participants provide scores on a scale of 0 (easy to breathe through the nose) to 100 (difficult to breathe through the nose) using a 100-mm line with 1-mm increments). Negative values indicate improvement in symptoms.
