Safety and Feasibility Study of Autologous Engineered Urethral Constructs for the Treatment of Strictures (NCT03258658)

A Phase 1 Pilot Safety and Feasibility Study of Autologous Engineered Urethral

🟒 Recruiting Phase1 πŸ’Š Investigational Drug / Biologic Sponsor: Wake Forest University Health Sciences

🩺 Plain-English Summary (8th-Grade Level)

This is a Phase I clinical study to determine the safety and efficacy of using autologous, engineered urethral constructs for the treatment of urethral strictures in adult males. The proposed study design is a prospective non-randomized and uncontrolled single-center investigation. Autologous urothelial cells (UCs) and smooth muscle cells (SMCs), obtained from enrolled male subjects' bladder tissue samples, will be culture expanded in vitro and used to seed tubular PGA scaffolds to create autologous urethral constructs for the repair of urethral strictures.
