Safety and Efficacy of Two Concurrent Injections of AA4500 in Adult Subjects With Multiple Dupuytren's Contractures

The primary objective of this study is to assess the safety of two concurrent injections of AA4500 into the same hand in subjects with multiple Dupuytren's contractures with palpable cords followed 24 to 72 hours later by a finger extension procedure and compare the rate of occurrence of targeted serious adverse events (tendon rupture/ligament injury and anaphylaxis) to historical rates of the same in clinical studies and post-marketing commercial use. The secondary objective is to evaluate the efficacy of two concurrent injections of AA4500.
