What this trial tests
NA trial testing Gana V® in Wrinkle in 59 participants. Completed in 7 May 2024.
Adults 30 to 70, any sex, with Wrinkle. Patients with the condition only — healthy volunteers not accepted.
Results — posted to ClinicalTrials.gov
Per-arm endpoint measurements with 95% confidence intervals where reported. Source: trial results section.
Change From Baseline in the Nasolabial Folds Severity Score on the Wrinkle Severity Rating Scale (WSRS) 6 Months After TreatmentPrimary· Baseline and Month 6
The Wrinkle Severity Rating Scale is a scale for measurement of the nasolabial folds wrinkles severity.
The scale ranges from Grade 1 (absent-better outcome) to Grade 5 (extreme-worse outcome) Change of grades was calculated as the value at 6 months minus the value at baseline. To observe an improvement of the nasolabial folds wrinkles, a decrease of the mean score was expected.

Change From Baseline in the Nasolabial Folds Severity Score on the Wrinkle Severity Rating Scale (WSRS)Secondary· Baseline, Month 1^1/2, Month 3, Month 6, Month 9, Month 12, Month 18 and Month 24
The Wrinkle Severity Rating Scale is a scale for measurement of the nasolabial folds wrinkles severity.
The scale ranges from Grade 1 (absent-better outcome) to Grade 5 (extreme-worse outcome) Change of grades was calculated as the value at month X minus the value at baseline. To observe an improvement of the nasolabial folds wrinkles, a decrease of the mean score was expected.
The Wrinkle Severity Rating Scale is a scale for measurement of the nasolabial folds wrinkles severity.
The scale ranges from Grade 1 (absent-better outcome) to Grade 5 (extreme-worse outcome) Responders rate = percentage of participants with an improvement of at least one grade in WSRS compared to baseline score. An improvement represents a decrease in WSRS (from grade 5 to grade 4 for instance)

Change From Baseline in Nasolabial Folds Average Depth (mm)Secondary· Baseline, Month 1^1/2, Month 3, Month 6, Month 9, Month 12, Month 18 and Month 24
The average depth of the nasolabial folds wrinkles was calculated using a fringe projection system. An increase of the mean value means a positive outcome.
Change was calculated as the value at each follow-up visit minus the value at baseline
