简要总结
The objective of this clinical trial is to evaluate the safety and effectiveness of a radiofrequency treatment device for the treatment of atrophic acne scars.
This is a prospective, multicenter, randomized, parallel-controlled, blinded-assessment, non-inferiority trial design.
The study aims to evaluate the effectiveness and safety of the radiofrequency therapeutic device manufactured by Sponsor for the treatment of atrophic acne scars, in comparison with the control device, the radiofrequency therapeutic device.
Participants will receive treatment sessions using either the investigational device or the control device, undergo follow-up evaluations after treatment to assess efficacy and safety outcomes.
The primary endpoint is Improvement in atrophic acne scars measured by the ECCA score compared with baseline, assessed 12 weeks after the final treatment.
The secondary efficacy endpoints include Global Aesthetic Improvement Scale (GAIS), Study Participant Satisfaction Assessment, Pain Score, Changes in skin characteristics compared with baseline Safety evaluations include Adverse events (AEs), Serious adverse events (SAEs)
