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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether combining pain neuroscience education (teaching patients about how pain works) with a gradual, timed increase in physical activity can reduce chronic pain in breast cancer survivors. About 122 survivors who have finished cancer treatment will be randomly assigned to either this combined program or usual care (an information leaflet). The goal is to see if the program lowers pain intensity and improves quality of life over three months, with follow-up lasting two years.

What this could mean

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

Active substance
Pain neuroscience education and behavioural graded activity
What this could lead to
If it works, this could offer a non-drug way to manage chronic pain and improve quality of life for breast cancer survivors.
What could go wrong
This is a relatively small, early-stage trial (122 participants) testing a behavioural intervention, so results may not apply broadly. The effect may be modest, and long-term benefits are uncertain.

Study facts

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

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

122 people

The number who actually took part.

Started

Oct 2020

Expected to finish

Dec 2028

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.

Ages

18 years and older

Sex

Female participants only

Healthy volunteers

Not accepted

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

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * To meet the definition introduced by the National Cancer Institute's Office of Cancer Survivorship, in which a cancer survivor is a patient with a history of cancer that is beyond the acute diagnosis and treatment phase. Patients need to be cancer-free and should have finished their primary treatment with a curative intent for at least 3 months prior to study participation. Adjuvant hormonal therapy and immunotherapy form the exception to the rule and are tolerated. * To report a pain severity of at least 3 out of 10 on pain visual analogue scale. * To be able to speak and read in Dutch in order to give informed consent and to complete the assessment tools. Written and signed consent will be obtained from all participants. Exclusion Criteria: * Suffering from dementia or cognitive impairment (unable to understand the test instructions and/or Mini Mental State Examination score \<23/30). * Suffering from severe psychological or psychiatric diseases. * Diagnosis of new neoplasms or metastases.
