Trial Outcomes & Findings for Safety and Effectiveness of Restylane® Kysse for Lip Augmentation in Chinese Subjects (NCT NCT05342753)

NCT ID: NCT05342753

Last Updated: 2025-12-22

Results Overview

The MLFS is a validated photograph-based outcome instrument that is designed specifically for quantifying lip fullness. Scoring of lip fullness from Grade 1 to 5 (grade 1: "Very Thin", grade 2: "Thin", grade 3: "Medium", grade 4: "Full" and grade 5: "Very Full"; with a higher score reflecting greater lip fullness) was based on visual live assessment by the Investigator. Percentage of participants with at least 1-point improvement from baseline on MLFS are reported for this outcome measure.

Participant Flow

This study was conducted from 13 June 2022 to 07 November 2024.

A total of 25 participants with a score of 1 (Very Thin) or 2 (Thin) on the Medicis Lip Fullness Scale (MLFS) were screened for the study, of which 3 were screen failures. 22 participants were treated with Restylane Kysse in at least 1 lip.

The WAS is a validated photograph-based outcome instrument that is designed specifically for quantifying facial folds. Scoring of fold severity is based on visual assessment of the length and apparent depth of the wrinkle at a certain time-point. Scoring of the upper perioral rhytids and oral commissures was based on visual live assessment by the investigator at defined time points; by using respective categorical scale ranging from Grade 0 to 5 where: grade 0 or 'No wrinkles', (1) 'Just perceptible wrinkle', (2) 'Shallow wrinkles', (3) 'Moderately deep wrinkle', (4) 'Deep wrinkle, well-defined edges', (5) 'Very deep wrinkle, redundant fold', higher grade represented higher fold severity. Responder was defined as a participant with at least a 1-point improvement from baseline.

The GAIS is a 7-point categorical scale ranging from -3 (Very Much Worse) to +3 (very much improved), used by the Treating Investigator to assess changes in the appearance of participants' lips following treatment by responding to the question: "With respect to the appearance of the participant's lips, how would you describe the result of the lip treatment compared to the photos taken before treatment?" by using the respective categorical scale as follows: Very Much Improved, Much Improved, Improved, No Change, Worse, Much Worse, Very Much Worse. In this outcome measure, percentage of participants who achieved at least 'Improved' on the GAIS assessed by treating investigator at Weeks 8, 16, 24, 32, 40, and 48 were reported.
