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 Results may not be published yet.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

Summary

This study investigates whether a personalized exercise program can improve physical performance and reduce fatigue in children and adolescents with cancer. Participants will engage in supervised and home-based training sessions during and after their cancer treatment. The goal is to see if regular exercise can ease the burden of cancer therapy and enhance overall well-being.

What this could mean

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

Active substance
Exercise training (behavioral intervention)
What this could lead to
If effective, this could establish exercise as a standard part of childhood cancer care, helping to reduce fatigue and improve quality of life during and after treatment.
What could go wrong
The study is exploratory and relatively small, so results may not be conclusive. Exercise may be challenging for children undergoing intensive treatment, and adherence could vary.

Who can take part

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

Who is studied

Eligible are children or adolescents from 3 to 21 years of age with a cancer diagnosis according to the International Classification of Childhood Cancer (ICCC). The term "childhood cancer" is most commonly used to designate cancer that arises in children before the age of 18 years. Since patients older than 18 years (especially in the transition phase from adolescence to young adulthood) can also have paediatric tumour entities, the upper age limit for study inclusion was set at 21 years. The Kolibri study includes patients for whom oncological treatment (regardless of the type of therapy) at the Paediatric Oncology Centre of the University Medical Centre Mainz is planned or already being carried out and who are not in the final stage of the disease.

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

Inclusion Criteria: * Oncological disease according to the International Classification of Childhood Cancer. * Planned or started anti-cancer treatment (chemo- and/or radiotherapy and/or surgery) at the Clinic and Polyclinic for Paediatrics and Adolescent Medicine of the University Medical Centre of the Johannes Gutenberg University Mainz or connection to the Paediatric Oncology Centre Mainz within the framework of aftercare. * The patient is assessed by the treating team (pediatric oncologist, exercise professional etc.) as suitable to participate in the trial, e.g. due to medical or psychological reasons. * Existing informed consent (or assent) to participate in the study. * The patient is not in a terminal phase of the disease. Exclusion criteria: * The patient is assessed by the treating team (pediatric oncologist, exercise professional etc.) as unsuitable to participate in the trial, e.g. due to medical or psychological reasons. * After detailed information and, if necessary, having time to consider, the patient (≥ 16 years of age) did not agree to give written informed consent to participate in the trial. In the case of minor patients (\<16 years of age): The legal guardians do not assume that the child/adolescent is able to freely decide on participation or to consent to participation on the basis of the information received, and do not consent to this themselves. * The patient (and the legal guardians) has/have insufficient knowledge of the German or English language, so that it is not possible to carry out both the informed consent and interviews (in age-appropriate language). * The patient is in a terminal phase of the disease.
