PLLA-LASYNPRO™ Injections for Skin Laxity Treatment

Sponsor: Nordberg Medical Italy srl

Summary

This single-center, open-label, intra-subject controlled proof-of-concept clinical study will evaluate the histological and clinical effects of Poly-L-lactic Acid (PLLA) LASYNPRO™ (Juläine) injections for treatment of skin laxity in patients requiring post-bariatric surgery. Fifteen participants will be enrolled. Each participant will serve as his or her own control, with one thigh treated with PLLA LASYNPRO™ and the contralateral thigh left untreated. Participants will receive 3 injections in the treated thigh over approximately 3 months, followed by planned post-bariatric plastic surgery at 3, 6, or 9 months after the last injection, depending on assigned group. During surgery, tissue samples from treated and untreated areas will be collected for histological evaluation. A follow-up visit will occur approximately 30 days after surgery. The primary endpoint is comparison of collagen type I and collagen type III between treated and untreated areas. Secondary endpoints include histological comparison of elastic fibers, stromal cell populations, inflammatory biomarkers, cell proliferation markers, and assessment of stretch marks, as well as safety. An exploratory endpoint is assessment of post-operative scar healing.
