Plain English Summary

Background and study aims
Dupuytren’s contracture is a common problem affecting the hand. The condition is caused by fibrous tissue which forces the finger to bend down into the palm meaning patients cannot straighten their finger. The common treatment is surgery to remove the tissue and straighten the bent finger. A new treatment is a Collagenase injection, which softens the fibrous tissue. This is given in clinic, and is followed up in clinic a few days later where the finger is moved to help to straighten it. Both treatments are offered on the NHS in England and are used in the USA and Europe, but it is not known if the injection is as good as surgery at correcting the bent finger, if the correction continues in the long term and if the complication rates are similar. The aim of this study is to find out whether collagenase injections are as good and as safe as surgery for treating this condition and to find out the cost of both treatments to see which is the best value for money. Participants are also asked what they think about the different treatments, to see if they prefer one treatment more than the other.

Who can participate?
Patients aged 18 and over who have Dupytren’s contracture

What does the study involve?
The participant’s hand is assessed and a photograph is taken, and the participant is asked some questions about their condition and their general health. Participants are then randomly allocated to receive either the injection or surgery. Before they receive their treatment, the hand is re-assessed and the participant completes a short questionnaire about their hand health. During the study participants come to the hospital for another 4 visits where their hand is assessed, they are asked some questions about their hand function and general health, and a photograph of their hand is taken.

What are the possible benefits and risks of participating?
The information from this study may help doctors to treat people with Dupuytren’s contracture more effectively in the future. However, as with any treatment, there are always potential risks. Common side effects of Collagenase include injection site swelling, bruising and pain. These often subside within 1 – 2 weeks of the injection. The injection may also cause dizziness, headaches, a tingling sensation or a reduced sense of touch. Very rarely, allergic reactions and tendon rupture may occur. Common side effects of surgery may be experienced such as pain, bruising, swelling or infection, in addition to anaesthetic side effects such as dizziness, headaches and numbness.

Study information

Scientific title

A pragmatic multi-centre randomised controlled non-inferiority, cost effectiveness trial comparing injections of collagenase into the cord to surgical correction in the treatment of moderate Dupuytren’s contracture in adult patients

Acronym

DISC

Study hypothesis

Collagenase injection is not inferior to limited fasciectomy in the correction of Dupuytren’s contracture of the hand.

Condition

Dupuytren's contracture

Intervention

The participant's hand is assessed, a photograph is taken and they are asked some questions about their condition and their general health. Participants are randomised to either the intervention or the control group. Before they receive their treatment, their hand is re-assessed and they are asked to complete a short questionnaire about their hand health.

1. Intervention: Collagenase Clostridium histolyticum injections
Depending on the cord affected 0.25ml or 0.20ml of reconstituted solution (0.58mg Collagenase Clostridium histolyticum) is injected as three aliquots: 0.25ml for cord in a metacarpophalangeal (MCP) joint, 0.20ml for cord in a proximal interphalangeal (PIP) joint. The three aliquots are distributed via injection into an affected cord at set anatomical points through a single needle puncture at a single time point. Patients will be scheduled for Collagenase injection within 18 weeks following randomisation (as per referral to treatment time RTT), however where possible sites should complete this procedure within 12 weeks post randomisation. After an interval of one to seven days, the patient then returns to clinic and, under local anaesthetic, the cord is snapped using a four-step process. Two additional visits by the patient may therefore be required for the intervention to be delivered; one for injection and one for manipulation. Separate cords may be injected at the same treatment, in line with the SmPC, following the injection procedure and using separate vials for each cord. If multiple cords are injected, only the reference cord injection will be deemed to be part of the trial treatment. Given the pragmatic nature of DISC, follow-up Collagenase injections will be at clinician discretion this includes the timing of manipulation and of further injections to the same cord.

2. Control: limited fasciectomy surgery
Limited fasciectomy involves the removal, under anaesthesia and tourniquet control, of the diseased fascia, nodule and cord, or a part of it, to correct the contracture of the joint. As deemed clinically appropriate, the skin may then be left to heal by secondary intention, closed directly, or closed with a Z plasty or closed using a full thickness skin graft. Patients will be scheduled for the limited fasciectomy surgery to be completed within 18 weeks following randomisation (as per referral to treatment time-RTT), however where possible sites should complete this procedure within 12 weeks post randomisation.

During the study participants need to come to the hospital for another 4 visits where their hand is assessed, they are asked some questions about their hand function and general health, and a photograph is taken of their hand.
