Saypha® Volume LIdocaine in Nasolabial Folds

Comparison of saypha Volume Lidocaine from 2 different manufacturing locations in correcting moderate to sever nasolabial folds

Following informed consent and screening, eligible subjects with moderate to severe nasolabial folds will be randomized to receive saypha® VOLUME Lidocaine from 1 of 2 manufacturing sites. The device will be injected into the deep dermis or supraperiostal, and subjects will return for follow-up assessments at Week 2, 4, 24, 36, 52 and optional at Week 65, 78 and 104 after the treatment. A Touch-up treatment may be done at Week 2, if deemed appropriate by the investigator. The performance of the investigational device will be evaluated by the investigator by assessing severity of nasolabial folds using the Nasolabial Folds Severity Rating Scale (NLF-SRS) at Week 4, 24, 36, 52 after the treatment and optional at Week 65, 78 and 104 and in comparison to Day 0. Telephone visits will be performed approximately 24 hours post-administration to monitor possible adverse events. In case any adverse events are reported during the telephone visits an unscheduled visit should be performed.
