NCT02725528

Brief Summary

This is a prospective, multi-centre, pragmatic randomized controlled trial to compare both the clinical effectiveness and cost-effectiveness of collagenase injections (CI) versus limited palmar fasciectomy (LPF) to determine if collagenase is a superior treatment in terms of improved quality of life and reducing recurrence of the disease without serious complications. Since collagenase injections are costly it is also important to know if this novel intervention is cost-effective from the patient, Ministry of Health and societal perspectives.

Outcome Measures

Primary Outcomes (1)

  • Health-related Quality of Life (HRQL) Using the Michigan Hand Outcomes Questionnaire (MHQ)

    Michigan Hand Outcomes Questionnaire (MHQ). Converted to a score rated 0-100 (where higher scores represent better function).

    1 year

Secondary Outcomes (8)

  • HRQL Measured With the Health Utility Index Mark 3 (HUI3) of Health

    1 year

  • HRQL Measured With the Unité Rhumatologique Des Affections de la Main (URAM)

    1 year

  • HRQL Measured With the Southampton Dupuytren's Scoring Scheme (SDSS)

    1 year

  • Quality Adjusted Life Years (QALY) Measured With the Health Utility Index Mark 3 (HUI3)

    1 year

  • Recurrence Rates

    1-4 years

  • +3 more secondary outcomes

Study Arms (2)

collagenase injection

ACTIVE COMPARATOR

This procedure will be performed either in a minor procedure room or the hand clinic as per surgeon's routine practice. Collagenase will be administered with or without local anesthesia. As this is a pragmatic study there may be more than one digit injected at a time just as surgery occurs on more than one digit at a time. A recently published study by Gaston et al confirmed that two concurrent injections of collagenase to 2 affected joints in the same hand are generally well tolerated and the frequency of most adverse events (AEs) is similar to those reported in studies that use single sequential injections.

Drug: collagenase injection

limited palmar fasciectomy

ACTIVE COMPARATOR

The Dupuytren's cord will be excised under local anesthesia in a minor procedure room setting or main operating room under local or general anesthetic depending on the complexity of the disease and the surgeon's routine. As this is a pragmatic study comparison of collagenase injections (novel intervention) to limited palmar fasciectomy as it is actually presently performed in all settings academic or community (local in minor room or general/local anesthetic in the main operating room) will be examined. Surgery will be performed according to the operating surgeon's preferred technique i.e. zig-zag Brunner incision or straight incision with z-plasty closure of the skin.

Procedure: limited palmar fasciectomy

Interventions

Also known as: enzyme, collagenase clostridium histolyticum, xiaflex

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Canadian Citizen
  • years of age or older
  • Dupuytren's contracture of the metacarpophalangeal (MCP) joint or of the proximal interphalangeal (PIP) joint with a fixed flexion contracture of 20º or greater in at least 1 finger (not the thumb)
  • Demonstrated inability to simultaneously place the affected finger and palm flat on a table
  • Able to understand and communicate in English

You may not qualify if:

  • Patients undergoing any concomitant procedure on the same hand (e.g. carpal tunnel release, stenosing tenosynovitis release)
  • Persistent extension deficit from a previous surgery of the same digit
  • Any chronic muscular or neuromuscular disorder affecting wrist or hand
  • Patient generally unfit for surgery
  • Patient with specific treatment preference
  • Bleeding disorder or recent stroke
  • Allergy to collagenase
  • Use of a tetracycline derivative within 14 days of first dose of study drug (because tetracycline derivatives may inhibit the collagenolytic activity of mammalian collagenase homologs \[i.e., matrix metalloproteinases\])
  • Pregnant or breast feeding patients
  • Patients who do not have insurance coverage for collagenase injections
  • Patients who are unable to provide informed consent or are unable to complete quality of life questionnaires due to mental capacity or neuro-psychological problems.

Limitations and Caveats

Limitations include small sample size, poor recruitment (due health insurance coverage, treatment preference, and the discontinuation of Xiaflex® in Canada), and poor response rate and outcome data collection due to onset and restriction associated with COVID-19 pandemic.
