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 This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether adding stem cells from the shoulder bursa and platelet-rich plasma (PRP) to standard rotator cuff repair helps the tendon heal better. About 200 adults with full-thickness supraspinatus tears will be followed for a year. Researchers will compare those who get the extra stem cells and PRP to those who get standard surgery alone, only stem cells, or only PRP.

What this could mean

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

Active substance
stem cells from the subacromial bursa and platelet-rich plasma (PRP)
What this could lead to
If it works, this could lead to a simple way to boost rotator cuff healing and reduce re-tears after surgery.
What could go wrong
This is an early observational study, not a randomized trial, so results may not prove cause and effect. The added stem cells and PRP may not improve outcomes over standard surgery alone.

Study facts

What this study's own registry entry says, in plain language.

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.

Participants

About 200 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

May 2026

An estimate. Start dates often move.

Expected to finish

Feb 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

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 Adult patients aged ≥18 years. Patients undergoing arthroscopic rotator cuff repair. Patients with a full-thickness, isolated, primary tear of the supraspinatus tendon. Patients considered eligible for arthroscopic rotator cuff repair using suture anchors. Ability and willingness to provide written informed consent. Willingness and ability to comply with the study protocol and scheduled follow-up visits. Exclusion Criteria Partial-thickness rotator cuff tears. Massive or irreparable rotator cuff tears. Revision rotator cuff repair. Concomitant tears of the subscapularis tendon, infraspinatus tendon, long head of the biceps tendon requiring surgical treatment, or glenoid labrum. Previous surgery on the affected shoulder. Glenohumeral osteoarthritis or advanced cuff tear arthropathy. Active infection or systemic inflammatory disease affecting the shoulder. Use of other biological augmentation techniques during surgery, such as collagen patch, stem cells, bone marrow aspirate concentrate, or other scaffold-based augmentation. Inability to provide informed consent. Inability or unwillingness to comply with the postoperative rehabilitation protocol or follow-up schedule.
