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

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.

Summary

This study uses blood samples from 20 dental patients to see how well a bone-growth protein (rhBMP-2) sticks to a natural blood-derived scaffold (E-PRF) and releases over time. Researchers compare this to the standard sponge carrier and combinations. The goal is to find a better way to deliver the protein for treating bone loss, but this is done in a lab, not in people.
