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 Results may not be published yet.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

Summary

Researchers at Mayo Clinic are running a pilot study to see whether clearing a blocked pancreatic duct improves how the pancreas makes insulin in people with chronic pancreatitis. Participants are adults with minimally symptomatic chronic pancreatitis and a duct blockage. The study randomly assigns them to receive an endoscopic procedure that clears the blockage or to not have the procedure, then measures insulin secretion over six months. The main goal is to find out whether a larger trial is feasible.

What this could mean

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

Active substance
endoscopic pancreatic duct decompression, a procedure that uses an endoscope to clear pancreatic duct blockages
What this could lead to
If the approach works, it could show that relieving a pancreatic duct blockage helps the pancreas make insulin, which might guide future treatment for chronic pancreatitis.
What could go wrong
This is a small pilot study with 30 people, so it may not produce clear answers or generalise to all patients. Endoscopic procedures carry risks such as pancreatitis, bleeding, or infection.
