Primary outcomePrimary: Differences Among the 3 Dosage Groups in the Patient (PSAS) and Observer (OSAS) Scar Assessment Scale (POSAS) Scores — 8.0; 8.0; 8.3; 6.8 Units on a scale — p=0.57
Summary
The purpose of this study was to determine the safety of AZX100 Drug Product and to determine whether it was effective in preventing or reducing scars that were made from trocars following arthroscopic shoulder surgery.
