Evaluation of the MJGS Following Radiesse (+) Injection Into the Jawline

Study Overview
=================
Brief Summary
-----------------
This study will evaluate the sensitivity of the validated Merz Jawline Grading Scale (MJGS) to detect treatment effects following Radiesse (+) correction of subcutaneous volume loss and contour deficits of the jawline. Treatment effects detected on the MJGS will be correlated with assessments of aesthetic outcomes on the Global Aesthetic Improvement Scale (GAIS) and FACE-Q instrument

Detailed Description
-----------------
A prospective, open label study, in which both right and left jawlines will receive treatment with Radiesse (+). Subjects will be randomized in a 2:1 ratio to either a treatment group or an untreated control group. Jawlines will be assessed by masked evaluators on the MJGS. Treating physicians and treatment group subjects will assess satisfaction on the GAIS. Treatment group subjects will self-report aesthetic outcomes on the FACE-Q instrument. Treatment subjects will be evaluated at enrollment, and 1, 2 and 4 weeks after enrollment. Control group subjects will be required to be evaluated at enrollment and 4 weeks after enrollment.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Jawlines Achieving Greater Than or Equal to (>=) 1-point Improvement on Merz Jawline Grading Scale (MJGS) at Week 4 | MJGS is a 5-point scale, where score ranges from (0-4) as, score 0: continuous jawline contour, no downshifting of subcutaneous volume; score 1: mild loss of jawline contour, mild downshifting of subcutaneous volume; score 2: moderate loss of jawline contour, moderate downshifting of subcutaneous volume; score 3: severe loss of jawline contour, severe downshifting of subcutaneous volume and score 4: very severe loss of jawline contour, diffuse mandibular angle, very severe downshifting of subcutaneous volume. | Week 4 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Treatment Group, Radiesse (+) Injectable Implant: Percentage of Jawlines With >=1-point Improvement on the MJGS Versus at Least an Improved Rating on Global Aesthetic Improvement Scale (GAIS) at Week 4 | MJGS is a 5-point scale, where score ranges from (0-4) as, score 0: continuous jawline contour, no downshifting of subcutaneous volume; score 1: mild loss of jawline contour, mild downshifting of subcutaneous volume; score 2: moderate loss of jawline contour, moderate downshifting of subcutaneous volume; score 3: severe loss of jawline contour, severe downshifting of subcutaneous volume, and; score 4: very severe loss of jawline contour, diffuse mandibular angle, very severe downshifting of subcutaneous volume. The GAIS is a 7-point scale, where score ranges from (0-7) as: score 0: very much worse; score 1: much worse; score 3: worse; score 4: no change; score 5: improved; score 6: much improved; score 7: very much improved. An improvement on the GAIS for the treating investigator was classified as investigators who rated participants as improved, much improved, or very much improved. All other ratings on the GAIS were classified as no improvement. | Week 4 |
