This was a Phase 3, 9-month, open-label study conducted in the United States. Subjects with a diagnosis of advanced Dupuytren's disease in a metacarpophalangeal (MP) or proximal interphalangeal (PIP) joint that resulted in a fixed flexion deformity of at least one finger, other than the thumb, that was at least 20° as measured by finger goniometry and was suitable for evaluation and injection were enrolled.

This study was designed to be part of the larger clinical program, for adult patients with Dupuytren's contracture with a palpable cord, where the data from 2 pivotal Placebo-Controlled studies (AUX-CC-857 (NCT00528606) and AUX-CC-859 (NCT00533273)) and 7 non-pivotal studies were evaluated.

Primary Outcome Measures:
  • Reduction in Contracture to 5° or Less [ Time Frame: Within 30 days after the last injection ]
    The Primary Outcome Measure is the percentage of 292 joints that were successfully treated where "successfully treated" was defined as reduction in contracture to 5° or less.

Secondary Outcome Measures:
  • Clinical Improvement After the Last Injection [ Time Frame: 30 days after last treatment ]
  • Percent Reduction From Baseline Contracture After the Last Injection [ Time Frame: 30 days after last treatment ]
  • Change From Baseline Range of Motion After the Last Injection [ Time Frame: 30 days after last treatment ]
  • Time to First Achieve and Maintain Clinical Success After the Last Injection [ Time Frame: First evaluation visit on which clinical success is achieved and maintained through the Day 30 evaluation ]
  • Clinical Success After the First Injection [ Time Frame: 30 days after first treatment ]
  • Clinical Improvement After the First Injection [ Time Frame: 30 days after first treatment ]
  • Percent Reduction From Baseline Contracture After the First Injection [ Time Frame: 30 days after first treatment ]
  • Change From Baseline Range of Motion After the First Injection [ Time Frame: 30 days after first treatment ]

Enrollment: 201
Study Start Date: October 2007
Study Completion Date: April 2009
Primary Completion Date: October 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: AA4500 0.58 mg Biological: collagenase clostridium histolyticum
Up to five injections of AA4500 into cord(s) of the affected hand(s). Each injection was separated by at least 30 days.
Other Names:
  • AA4500


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects with a diagnosis of advanced Dupuytren's disease, with a fixed flexion deformity of at least one finger, other than the thumb, that had a contracture at least 20°, but not greater than 100° for MP (80° for PIP) joints, caused by a palpable cord.
  • Had a positive "table top test," defined as the inability to simultaneously place the affected finger(s) and palm flat against a table top.
  • Were naïve to AA4500 treatment or had received one or two injections of AA4500 for the treatment of advanced Dupuytren's disease in Auxilium Studies AUX-CC-851, AUX-CC-853, or AUX-CC-855.
  • Were judged to be in good health.

Exclusion Criteria:

  • Had a chronic muscular, neurological, or neuromuscular disorder that affected the hands.
  • Had received treatment for advanced Dupuytren's disease within 90 days of enrollment on the joint selected for the initial injection of AA4500, including surgery (fasciectomy or surgical fasciotomy), needle aponeurotomy/fasciotomy, or injection of verapamil and/or interferon.
  • Had a known recent history of stroke, bleeding, a disease process that affected the hands, or other medical condition, which in the investigator's opinion, would make the subject unsuitable for enrollment in the study.
