Introduction

Injectable collagenase clostridium histolyticum (CCH) is a minimally invasive non-surgical therapy with efficacy in correcting Dupuytren's contracture (DC). In the concurrently run JOINT I and JOINT II studies, designed to follow clinical practice, we evaluated the efficacy of ?5 CCH injections in patients with DC.

Methods

JOINT I and II were multicenter, 9-month, open-label studies in which DC patients with primary flexion deformities ?20° received ?3 CCH (0.58 mg) injections/joint (?5 injections/patient) at 30-day intervals into joints prioritized by extent of contracture. After the first injection, patients could opt to receive up to 2 additional injections in same cord or other cords regardless of outcome for the first joint. The primary endpoint was reduction in contracture to ?5° 30 days after the last injection. Data from JOINT I and II were pooled.
