  Purpose

The purpose of the study is to determine if collagenase will reduce the degree of contracture in the primary joint in subjects with Dupuytren's disease.

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 and AUX-CC-859) and 7 non-pivotal studies were evaluated.

Primary Outcome Measures:
  • Primary Outcome Measure is Reduction of Flexion Contracture of the Primary Joint. [ Time Frame: 30 days after the last injection ] [ Designated as safety issue: No ]

    The Primary Outcome Measure for patients treated with AA4500 is the percentage of 23 joints that were successfully treated where "successfully treated" was defined as reduction in contracture to 5° or less.

    The Primary Outcome Measure for placebo treated patients is the percentage of 12 joints that were successfully treated where "successfully treated" was defined as reduction in contracture to 5° or less.



Secondary Outcome Measures:
  • Percent Reduction From Baseline Contracture After the Last Injection [ Time Frame: 30 days after last treatment to the primary joint ] [ Designated as safety issue: No ]
  • Percent Change From Baseline Range of Motion After the Last Injection [ Time Frame: 30 days after last treatment to the primary joint ] [ Designated as safety issue: No ]
  • 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 of the primary joint ] [ Designated as safety issue: No ]
  • Clinical Success After the First Injection [ Time Frame: 30 days after first treatment to the primary joint ] [ Designated as safety issue: No ]
  • Percent Reduction From Baseline Contracture After the First Injection [ Time Frame: 30 days after first treatment to the primary joint ] [ Designated as safety issue: No ]
  • Change From Baseline Range of Motion After the First Injection [ Time Frame: 30 days after first treatment to the primary joint ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: AA4500 0.58 mg Biological: collagenase clostridium histolyticum
Subjects could have received up to three injections of AA4500/placebo into the cord of the affected hand. Each injection was separated by at least 30 days. Individual cords may have received up to a maximum of three injections.
Other Names:
  • XIAFLEX®
  • AA4500
Placebo Comparator: placebo Biological: collagenase clostridium histolyticum
Subjects could have received up to three injections of AA4500/placebo into the cord of the affected hand. Each injection was separated by at least 30 days. Individual cords may have received up to a maximum of three injections.

  • XIAFLEX®
  • AA4500

Detailed Description:

In a random, placebo controlled, double blind study, collagenase injection therapy will be investigated for it's ability to disrupt the Dupuytren's cord.

Resultant cord disruption may obviate the need for patients to have surgery to correct the finger flexion contractures of Dupuytren's disease.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subjects were at least 18 years of age, of either sex or any race.
  • Subjects had residual Dupuytren's disease with a fixed-flexion deformity of the finger(s) of at least 20 degrees or greater, caused by a palpable cord.
  • Subjects had a positive "table-top test" defined as the inability to simultaneously place their affected finger(s) and palm flat against a table top.
  • Subjects must have been willing to participate in and complete the study, and comply with its procedures by signing an IRB approved written consent form.
  • Subjects must have been able to understand and adhere to the visit schedule. They must have been able to follow study procedures and instructions, and have agreed to report concomitant medications and adverse events accurately and consistently.
  • Women of childbearing potential must have agreed to use an acceptable method of birth control or must have been surgically sterilized (hysterectomy or tubal ligation). Women of childbearing age had a urine pregnancy test on Day 0 (day of injection) prior to the injection.

Exclusion Criteria

  • Women who were nursing or who were pregnant (as evidenced by a positive urine pregnancy test at the time of enrollment).
  • Subjects who had participated in an investigational drug trial within 30 days of enrollment in this study.
  • Subjects who had received surgery for Dupuytren's disease within 30 days of enrollment in this study.
  • Subjects who had a known allergy to AA4500 or any of the inactive ingredients in the AA4500 injection.
  • Subjects who had a known allergy to doxycycline.
  • Subjects who had a medical condition that would have made them unsuitable for enrollment.
