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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This phase 2 trial tests whether a higher dose of proton radiation combined with the oral chemotherapy drug capecitabine can help people with unresectable pancreatic cancer live longer and possibly become candidates for surgery. The study enrolls 60 patients whose tumors cannot be removed or who are not healthy enough for surgery. The goal is to see if this intense local treatment improves survival and surgical rates compared to historical outcomes.

What this could mean

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

Active substance
Proton radiation and capecitabine (oral chemotherapy)
What this could lead to
If successful, this approach could help more people with pancreatic cancer become eligible for surgery and extend survival.
What could go wrong
This is a small, early-phase trial with only 60 participants, so results may not apply broadly. The treatment involves intense radiation and chemotherapy, which can cause side effects.
