Collagenase Clostridium histolyticum (CCH) is a non-surgical, efficacious therapy for Dupuytren's contracture (DC). This study evaluated the efficacy and safety of CCH in patients with previous DC surgery. Data from 12 CCH clinical trials were pooled. At screening, patients provided details about the type/date of previous DC surgery. Reviewers coded descriptions to the Operated Hand, finger, and joint. Of 1082 patients, 422 (39%) had previous DC surgery. For these patients with previous surgery, the CCH treatment was coded on the Operated (n = 206) or Non-operated Hand (n = 196). End-points included changes in fixed-flexion contracture (FFC) and range of motion (ROM). Adverse events (AEs) were monitored. After treatment with CCH, FFC at metacarpophalangeal joints was reduced by 75% in previously Operated Hands and by 80% for Non-operated Hands (p = 0.6). Improvements in ROM were 32 degrees and 32 degrees, respectively (p = 0.9). For proximal inter-phalangeal joints, the reductions in FFC for the Operated and Non-operated Hands were 52% and 50%, respectively (p = 0.6); improvements in ROM: were 24 degrees and 26 degrees, respectively (p = 0.3). Some AE rates were significantly higher in the Operated vs Non-operated Hand groups, but were not clinically relevant. There were no between-group significant differences in AE duration (p > 0.08). Previous surgery for DC does not affect efficacy or safety of CCH, suggesting CCH is an option in patients with recurring DC. Some AE rates were significantly higher, but not clinically relevant.
