What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether wrapping a repaired hand tendon with a special collagen sheet could prevent scar tissue from forming and improve hand movement. Sixty adults with cut extensor tendons in their hand or wrist were randomly assigned to get either standard tendon repair alone or repair plus the collagen wrap. The main goal was to measure how much the fingers could move after healing.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
High-Purity Type I Collagen (HPTC) Wrap
What this could lead to
If it works, this collagen wrap could reduce scarring and stiffness after hand tendon repair, helping people regain better hand movement and function.
What could go wrong
This is a small, completed trial with only 60 participants. The collagen wrap is a device, not a drug, and its benefits may not be large or apply to all tendon injuries. There is always a risk of infection or poor healing with any surgical implant.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age 18-65 years. 2. Acute open laceration of extensor tendons in zone VI, VII, or VIII of the hand / wrist (according to Verdan's classification), involving digits 2-5 and/or wrist extensors. 3. Complete tendon laceration (≥50% tendon cross-sectional area), requiring primary repair. 4. Time from injury to surgical repair ≤72 hours. 5. Single upper limb involved. 6. Ability and willingness to comply with postoperative rehabilitation protocol and follow-up visits. 7. Provision of written informed consent. Exclusion Criteria: 1. Crush, avulsion, or segmental tendon loss requiring graft or tendon transfer. 2. Associated open fractures requiring dorsal plating across the repair site, or extensive bone loss affecting joint stability. 3. Previous surgery or significant scarring over the injured extensor tendon region. 4. Associated major nerve injury requiring graft or complex reconstruction (digital nerve repair without grafting may be allowed if balanced between groups). 5. Uncontrolled systemic illness (e.g., HbA1c \> 8.5% for diabetes, severe peripheral vascular disease, chronic steroid use, severe malnutrition). 6. Active infection at the injury site. 7. Known allergy or hypersensitivity to bovine/ovine collagen or any component of HPTC. 8. Pregnancy or lactation. 9. Inability to provide informed consent or comply with follow-up.
