Purpose
The purpose of this research study is to evaluate the safety and effectiveness of injection with DGE Injectable Gel (manufactured by Genzyme Biosurgery) as compared to injection with a Food and Drug Administration (FDA) approved dermal filler in patients undergoing cutaneous correction of the nasolabial folds (NLFs).

Experimental: DGE
Participants received DGE in one nasolabial fold (NLF) of one side of their face (blinded, split-face study design) in the Initial Treatment period. For those that continued into the Repeat Treatment Period, they received DGE in all NLFs as an open-label treatment.
|
Device: Dermal Gel Extra (DGE)
Dermal Gel Extra (DGE) Injectable Gel was administered only to the nasolabial folds via the intradermal route. The Principal Investigator was instructed to inject a sufficient amount of DGE to ensure full correction of the NLF wrinkles (i.e., to the optimal level of correction achievable).

Active Comparator: Restylane
Participants received Restylane in one nasolabial fold (NLF) of one side of their face (blinded, split-face study design) in the Initial Treatment period.
|
Device: Restylane
Restylane was administered only to the nasolabial folds via the intradermal route. The Principal Investigator was instructed to inject a sufficient amount of Restylane to ensure full correction of the NLF wrinkles (i.e., to the optimal level of correction achievable).

Detailed Description:
This study included an Initial and a Repeat Treatment period. The Initial Treatment period was a subject and evaluator-blinded, randomized split face study in which subjects received DGE in one nasolabial fold and Restylane in the other nasolabial fold.
In the Repeat Treatment Period, participants received DGE in both NLFs.
Eligibility| Ages Eligible for Study: | 18 Years and older |

| Accepts Healthy Volunteers: | No |
Inclusion Criteria (abbreviated list):
- Bilateral nasolabial folds with severity score of 3 or 4 on the 6 point scale
Exclusion Criteria (abbreviated list):
- Pregnant/lactating women
- Subjects who have an allergy to lidocaine, prilocaine or other amide-type anesthetic
- Had a chemical peel at the NLF area within 4 weeks prior to study entry. In addition, subjects were restricted from undergoing chemical peels at the NLF area for the duration of the study.
Had any treatment with Botox® injections:
- in the upper 1/3 of the face within 2 weeks prior to entry into the study, or
- in the lower 2/3 of the face within 24 weeks prior to entry. In addition, subjects were restricted from receiving Botox injections in the face for the duration of the study.
- Received prior therapy to the face and/or neck (e.g., dermabrasion, face-lift, Thermage®,laser resurfacing, contour threads, non-ablative laser treatments) within 24 weeks prior to study entry. In addition, subjects were restricted from undergoing such therapy for the duration of the study.
- Had previous tissue augmentation at the NLF area within 24 weeks prior to study entry.In addition, subjects were restricted from undergoing tissue augmentation at the NLF area for the duration of the study.
- Had previous treatment at the NLF area with permanent implants (e.g., silicone,Softform®) or long-lasting fillers (e.g., RadiesseTM, Sculptra®, ArteFill® [Artecoll], or Bio-AlcamidTM). In addition, subjects were restricted from undergoing treatment with permanent implants or long-lasting fillers at the NLF area for the duration of the study.
- Had evidence of scar-related disease or delayed healing activity within 1 year prior to study enrollment. (Note: subjects with scars were eligible for study enrollment, although scars at the intended treatment sites were not treated.)
- Had a history of keloid formation.
- Had a history of hypo- or hyperpigmentation of the skin.
- Had any infection, unhealed wound, or active inflammatory process (e.g., skin eruptions such as cysts, pimples, rashes, or hives) at the injection site(s).
- Immunocompromised/immunosuppressed (e.g., HIV-positive, transplant recipient, or presently receiving chemotherapy).
