• 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 one 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).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
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. Participants who continued into the Repeat Treatment period were treated with DGE as an open-label treatment.	Device: Dermal Gel Extra (DGE); Dermal Gel Extra (DGE) Injectable Gel contains hyaluronic acid with lidocaine. DGE was administered to 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). Up to 2 touch-up treatments were allowed in the Initial Treatment period.; Other Names: PREVELLE Lift; hyaluronic acid and lidocaine; Drug: EMLA Cream; EMLA Cream (Eutectic Mixture of Local Anesthetics) is an FDA-approved topical anesthetic comprised of 2.5% each of lidocaine/prilocaine. EMLA Cream was applied in approximately equal amounts prior to all injections of DGE and Restylane.; Other Names: lidocaine; prilocaine
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.	Drug: EMLA Cream; EMLA Cream (Eutectic Mixture of Local Anesthetics) is an FDA-approved topical anesthetic comprised of 2.5% each of lidocaine/prilocaine. EMLA Cream was applied in approximately equal amounts prior to all injections of DGE and Restylane.; Other Names: lidocaine; prilocaine; Device: Restylane; Restylane was administered to 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). Up to 2 touch-up treatments were allowed in the Initial Treatment period.; Other Names: dermal filler; hyaluronic acid

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in the Blinded Evaluator's Assessment of Nasolabial Fold (NLF) Wrinkle Severity at Week 24	This was a comparison of the mean change between Baseline and the Week 24 score (baseline minus week 24 scores) in the blinded evaluators' assessments of NLF wrinkle severity. A positive value for the mean change indicates an improvement. Genzyme 6-Point Grading Scale (GGS) for NLF was used for the assessment. A GGS score of zero indicates no wrinkles and a score of 5 indicates very deep wrinkles with redundant folds.	Week 24

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Participant's Pain Assessment During the Initial Treatment Measured on a Visual Analog Scale (VAS)	The pain experienced by each participant at the time of injection (time 0) and at 15 and 30 minutes after injection during the initial treatment visit was evaluated. Pain was measured using a VAS of 0 mm (no pain) to 100 mm (extreme pain).	Day 1
Change From Baseline in the Blinded Evaluator's Assessment of Nasolabial Folds (NLF) Wrinkle Severity at Week 36	Mean change between Baseline and the Week 36 score (Baseline minus week 36 scores) in the blinded evaluators' assessments of NLF wrinkle severity. A positive value for the mean change indicates an improvement. Genzyme 6-Point Grading Scale (GGS) for NLF was used for the assessment. A GGS score of zero indicates no wrinkles and a score of 5 indicates very deep wrinkles with redundant folds.	Week 36
Number of Participants With at Least a 1 Point Improvement From Baseline in the Blinded Evaluator's Assessment of Wrinkle Severity at Week 24	Count of participants with at least a 1-point improvement from Baseline in the Genzyme 6-Point Grading Scale (GGS) at Week 24. A GGS score of zero indicates no wrinkles and a score of 5 indicates very deep wrinkles with redundant folds.	Week 24
Participant Product Preference at Week 24	Participants indicated their product preference at Week 24 after Date of Optimal Correction (DOC).	Week 24
Participant Product Preference at Week 36	Participants indicated their product preference at Week 36 after Date of Optimal Correction (DOC).	Week 36
Number of Participants With Treatment-Emergent Adverse Events During the Initial Treatment Period	Counts of participants with treatment-emergent adverse events (AEs) from the time of injection up to Week 36. AEs are presented regardless of relationship to study device and/or procedure. If a participant had more than one occurrence of the same AE, he/she was counted only once. The most severe occurrence of an AE, as well as the most extreme relationship of the AE to the device, was indicated in cases of multiple occurrences of the same AE. For AEs by relationship, procedure-related and device-related AEs are not mutually exclusive and therefore are not additive.	Weeks 1-36
Number of Participants With Treatment-Emergent Adverse Events During the Repeat Treatment Period	Count of participants with treatment-emergent adverse events (AEs) from the time of injection for the repeat treatment period up to week 47. AEs are presented regardless of relationship to study device and/or procedure. If a participant had more than one occurrence of the same AE, he/she was counted only once. The most severe occurrence of an AE, as well as most extreme relationship of the AE to the device, was indicated in cases of multiple occurrences of the same AE. For AEs by relationship, procedure-related and device-related AEs are not mutually exclusive and therefore are not additive.	weeks 36 up to 47 weeks
