Retreatment of Recurrent Dupuytren's Contractures

Phase 4
Completed
Conditions
Dupuytren's Disease
Interventions
Biological: Collagenase clostridium histolyticum
Registration Number
NCT01498640
Lead Sponsor
Endo Pharmaceuticals
Brief Summary

The objectives of this study are to assess the safety and efficacy of AA4500 in the retreatment of recurrent contractures in joints that were effectively treated with AA4500 in a previous Auxilium-sponsored Phase 3 study.

Detailed Description

Open-label, Phase 4 study in subjects who are currently participating in the long-term follow-up study (ie, AUX-CC-860) in the United States, Australia, or Europe and who have recurrence of contracture (ie, joint contracture increases by at least 20 degrees compared with the Day 30 value after the last injection in a Phase 3 Auxilium-sponsored study and a palpable cord present) in a joint that was effectively treated (ie, reduction in contracture to 5 degrees or less 30 days after the last injection) with AA4500 in a Phase 3 Auxilium-sponsored study.

Subjects who experience recurrence of contracture in one or more effectively treated joints may be enrolled in this retreatment study after the investigator determines subject eligibility and after informed consent has been obtained. The investigator will treat the cord affecting the recurrent joint with up to three injections. Only one recurrent joint will be treated in this study.

Primary Outcome Measures
NameTimeMethod
Clinical Success30 days after last injection

Clinical success defined as reduction in fixed-flexion contracture to less than or equal to 5 degrees 30 days after the last injection of AA4500

Percent Change From Baseline in Degree of ContractureBaseline and 30 days after last injection

Change in fixed-flection contracture measured in degrees where a decrease of 100% would correspond to a reduction in contracture to 0 degrees

Change in Range of MotionBaseline and 30 days after last injection

Range of motion defined as difference between full flexion angle and full extension angle expressed in degrees

Secondary Outcome Measures
NameTimeMethod
Subject Global Assessment of Satisfaction30 days after last injection

Subject global assessment of overall treatment satisfaction

Recurrence of ContractureDay 365

Recurrence of contracture in the joint at day 365 that was successfully treated 30 days after last injection assessed. Recurrence was defined as 20 degree or greater increase of contracture of the treated joint at day 365 or medication intervention of the treated joint between the 2 time points.

Physician Global Assessment of Improvement30 days after last injection

Physician global assessment of change (improvement) in subject's Dupuytren's contracture
