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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 study explores whether cancer patients can safely receive proton radiation therapy while sitting upright instead of lying down. The upright system is already FDA-cleared, and the goal is to see if it works reliably for a range of patients. Researchers will track treatment success, quality of life, and satisfaction. If proven feasible, upright therapy could offer a more comfortable option for those who have difficulty lying flat.

What this could mean

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

Active substance
upright proton therapy
What this could lead to
If successful, this approach could make proton therapy more comfortable and accessible for cancer patients who cannot lie flat.
What could go wrong
This is an early feasibility study, so it may not show clear benefits over standard lying-down treatment, and not all patients may be able to complete therapy upright.

Study facts

What this study's own registry entry says, in plain language.

Participants

About 450 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

Sep 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

(i) Up to 450 participants are expected to be enrolled at Stanford-affiliated site(s). (ii) The total number of participants expected to enroll across all sites is 450, as this is a single-site study conducted at Stanford-affiliated facilities. (iii) Participants will be pediatric and adult patients with cancer who are being considered for treatment with upright proton therapy as part of their standard clinical care. These participants are appropriate for the study because the purpose is to evaluate the feasibility of delivering upright proton therapy in patients who would otherwise be eligible for proton radiation treatment.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.
