What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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.

Summary

This study tests whether a new, concentrated version of a patient's own blood platelets (called self-repair factor) works better than standard platelet-rich plasma (PRP) injections for knee osteoarthritis. 90 adults with mild to moderate knee arthritis will receive either the new factor, PRP, or a placebo. The goal is to see which treatment best reduces pain and improves knee function over six months.

What this could mean

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

Active substance
Lyophilized self growth factor (a concentrated form of the patient's own blood platelets)
What this could lead to
If it works, this could offer a more effective injection treatment for knee osteoarthritis pain and stiffness, potentially better than current PRP therapy.
What could go wrong
This is a small, early-stage trial with only 90 people. The new treatment may not prove better than PRP or placebo, and individual results vary.
