Dupuytren Contracture Recurrence Following Treatment With Collagenase Clostridium histolyticum (CORDLESS [Collagenase Option for Reduction of Dupuytren Long-Term Evaluation of Safety Study]): 5-Year Data.

Abstract

PURPOSE:

Collagenase Option for Reduction of Dupuytren Long-Term Evaluation of Safety Study was a 5-year noninterventional follow-up study to determine long-term efficacy and safety of collagenase clostridium histolyticum (CCH) treatment for Dupuytren contracture.

METHODS:

Patients from previous CCH clinical studies were eligible. Enrolled patients were evaluated annually for contracture and safety at 2, 3, 4, and 5 years after their first injection (0.58 mg) of CCH. In successfully treated joints (≤ 5° contracture following CCH treatment), recurrence was defined as 20° or greater worsening (relative to day 30 after the last injection) with a palpable cord or any medical/surgical intervention to correct new/worsening contracture. A post hoc analysis was also conducted using a less stringent threshold (≥ 30° worsening) for comparison with criteria historically used to assess surgical treatment.

RESULTS:

Of 950 eligible patients, 644 enrolled (1,081 treated joints). At year 5, 47% (291 of 623) of successfully treated joints had recurrence (≥ 20° worsening)-39% (178 of 451) of metacarpophalangeal and 66% (113 of 172) of proximal interphalangeal joints. At year 5, 32% (198 of 623) of successfully treated joints had 30° or greater worsening (metacarpophalangeal 26% [119 of 451] and proximal interphalangeal 46% [79 of 172] joints). Of 105 secondary interventions performed in the successfully treated joints, 47% (49 of 105) received fasciectomy, 30% (32 of 105) received additional CCH, and 23% (24 of 105) received other interventions. One mild adverse event was attributed to CCH treatment (skin atrophy [decreased ring finger circumference from thinning of Dupuytren tissue]). Antibodies to clostridial type I and/or II collagenase were found in 93% of patients, but over the 5 years of follow-up, this did not correspond to any reported clinical adverse events.

CONCLUSIONS:

Five years after successful CCH treatment, the overall recurrence rate of 47% was comparable with published recurrence rates after surgical treatments, with one reported long-term treatment-related adverse event. Collagenase clostridium histolyticum injection proved to be an effective and safe treatment for Dupuytren contracture. For those receiving treatment during follow-up, both CCH and fasciectomy were elected options.
