RHA® 3 Versus Restylane-L® for Lip Augmentation
NCT04540913 · View on ClinicalTrials.gov ↗
Study Summary
This is a multicenter, double-blinded, randomized, prospective, controlled clinical study to identify whether RHA® 3 is non-inferior to Restylane-L® for lip augmentation at Week 12 after the last treatment (initial or touch-up). At screening, the treating investigator (TI) will evaluate the subject's lip fullness using the validated Teoxane Lip Fullness Scale (5-grade) for eligibility of the subject for the study. At screening, the blinded live evaluator (BLE) will evaluate the subject's lip fullness using the TLFS to confirm eligibility and to establish a pre-treatment score for assessment of effectiveness. Enrolled subjects will be randomly assigned in a 3:1 ratio to either the RHA® 3 or the Restylane-L® treatment group. Subjects will be blinded to the study treatment. The TI will administer the fillers, and if necessary, subjects will receive a touch-up treatment 4 weeks after the initial treatment to optimize the results. If the touch-up treatment is administered, the subject will be asked to come to the site for an additional visit 4 weeks after the touch-up injection. The study duration was extended from 36 to 52 weeks once all subjects had already been enrolled. Nearly 60% of the subjects consented to extend the study to 52 weeks before being eligible for repeat treatment. All data are presented up to 52 weeks (as well as 4 more weeks follow-up after retreatment at 36 or 52 weeks). Subjects will be followed for 36 to 52 weeks after their last treatment (initial treatment or touch-up), at which point, they will be offered re-treatment with RHA® 3, regardless of their original treatment, provided that the TI deems the treatment to be appropriate and the subject agrees. Reasons for not administering the re-treatment will be documented. The subject will then be followed for an additional 4 weeks before exiting the study. If the subject or the TI declines re-treatment, this visit (36 or 52 weeks after the last treatment) will be considered the study Exit vis

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04540913
The ClinicalTrials.gov registry entry for NCT04540913 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 202 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Teoxane, which has 3 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Lip appearing as the primary indexed condition, and to 2 interventions — of which Restylane-L is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04540913 reports 1 study location spanning 1 distinct geographic area — top geographies include Florida. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
