Evaluation of Juläine (TM) for the Treatment of Atrophic Facial Acne Scars

This is a multicenter, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the efficacy and safety of Juläine, a sterile injectable medical device composed of polylactic acid microspheres in a carboxymethylcellulose gel, for the treatment of moderate to severe facial atrophic acne scars. A total of 55 adult participants will be enrolled across selected dermatology sites in Poland. Forty-five participants will be randomized to receive Juläine, and ten participants will be randomized to receive a placebo (sterile saline solution). All participants will receive three treatment sessions administered over a two-month period (Day 0, Day 30, and Day 60), with injections targeted to areas affected by atrophic scars. The primary endpoint is the improvement in acne scars at 12 months from baseline, assessed by blinded evaluators using the Acne Scar Rating Scale (ASRS). Secondary outcomes include subject-reported satisfaction, improvement assessments using the Global Aesthetic Improvement Scale (GAIS), and objective skin texture measurements evaluated through imaging systems such as Canfield VISIA. Safety will be monitored through the collection of adverse events, local tolerability assessments, and follow-up visits over a 12-month period. The study is conducted in compliance with ISO 14155:2020 and EU MDR regulations, and has received ethics approval from the Bioethics Committee of the Regional Medical Chamber in Gdańsk, Poland.
