Gene Expression
Conditions
Brief summary
To compare gene expression stimulated by a semi-permanent filler and a biostimulator via punch biopsy
Detailed description
This is a randomized, single-center, comparative study to evaluate gene expression after treatment with a semi-permanent filler or a biostimulator. This study is designed to enroll and randomize approximately 20 subjects in a 1:1 ratio of treatment to PLLA or CaHA. All randomized subjects are to have contour deficiency at the nasolabial folds. Eligible subjects randomized to receive punch biopsy followed by treatment injection by the Treating Investigator at baseline. The method of injection was at the discretion of the Treating Investigator. A sufficient amount of product is injected to achieve optimal correction of the nasolabial folds, in the opinion of the Treating Investigator. PLLA group receives a second treatment at week 4 while CaHA group receives an optional touch-up if needed. All subjects have final follow-up visit for a second punch biopsy on the other side of the nasolabial fold.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Analyze gene expression via punch biopsy | 12 weeks after baseline | Summary of fold change using by relative quantification method at week 12. Gene expression analysis is performed via qPCR processing using a panel of biomarkers related to scar tissue formation, collagen, elastin, extracellular matrix integrity, epidermal barrier, anti-aging, antioxidant, cell renewal/regeneration, inflammation, growth factor, and hydration among others. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluate volume change in the treated area using 3D imaging | 4 and 12 weeks after baseline | Summary of total volume change in the nasolabial fold area measured by 3D photography at each visit. Total volume change corresponds to net volume change from baseline in the nasolabial fold. |
