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 Results may not be published yet.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

Summary

Researchers are testing a hydrogel coating called MectaShield that is applied to hip revision implants during surgery. The coating is designed to act as a barrier against bacteria that can cause joint infections. The trial compares two groups: one receives implants with the coating, and the other receives standard implants without it. The main goals are to check whether the coating affects how well the implant stays stable in the bone and to see if it reduces early infections.

What this could mean

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

Active substance
a hydrogel coating applied to hip replacement implants
What this could lead to
If it works, the coating could offer a way to lower the risk of infection after revision hip surgery without changing the implant itself.
What could go wrong
This is a small, early feasibility study with 56 people at one hospital. The coating might not reduce infections, and it could interfere with how well the implant settles into the bone.
Why investors are watching

Medacta is testing MectaShield, a hydrogel coating applied to hip and cup implants during cementless revision hip arthroplasty, in a 56-person feasibility study that measures implant stability, infection rate, function, and adverse events against a control group. For a small-cap company, a clean result on safety and early performance would give it clinical evidence for a product line it sells, while a poor result would remove that support.

If it works: A positive readout may support further studies and give surgeons and buyers reason to adopt MectaShield as an infection-prevention option in revision hip surgery.

If it fails: The trial is small and early, so it may not show a clear benefit, and a safety signal or failure to meet its stability and infection goals may slow or stop the program.
