Brief Summary

This mono-center clinical investigation is intended to evaluate the safety and effectiveness of THIODERM STRONG (test device) in the correction of moderate to severe midface volume deficit compared to Juvéderm® VOLUMA® Lidocaine (comparator device).

Detailed Description

The Investigation is an exploratory, prospective, randomized, subject and evaluator-blinded, split- face, single-centre study investigating the effectiveness and safety of THIODERM STRONG compared to Juvéderm® VOLUMA® Lidocaine for the treatment of moderate to severe midface volume deficit. 20 eligible Subjects will be included in this investigation, after the informed consent form (ICF) has been signed and relevant pre-treatment procedures, including medical history and pregnancy testing, have been performed. Subjects will receive injection in the midface region using THIODERM STRONG and Juvéderm® VOLUMA® Lidocaine until an optimal aesthetic result is achieved. The Blinded Evaluating Investigator will determine severity of the Subject's midface volume deficit using the 5-point MVDSS throughout the investigation (Baseline to Week 24). Baseline is defined as the assessment prior to administration of the IMDs. The same Investigator will assess the Subject using the 5-point MVDSS at all visits. An optional touch-up treatment can be performed at Week 4 upon discretion of the Unblinded Treating Investigator. The effectiveness and safety of the treatment will be evaluated after Day 1, 3 and 7 as well as at 4, 8, 16 and 24 weeks using objective and subjective outcome parameters. An interim analysis will be performed when all Subjects have completed the visit at Week 8.
