About this study
Official title: Effect of Methylphenidate on Cancer-related Fatigue in Patients Treated for a Brain Tumor During Childhood or Adolescence: Protocol for a Randomized, Double-blind, Placebo-controlled Crossover Trial - the EMBRAIN Trial
Cancer-related fatigue is a common and debilitating late effect in pediatric brain tumor survivors. Currently, evidence-based recommendations to ameliorate this condition are lacking.
The researchers will investigate the ability of methylphenidate to improve fatigue and cognition in pediatric brain tumor survivors suffering from cancer-related fatigue. Methylphenidate is a drug (central nervous stimulant) most commonly used in the treatment of hyperkinetic disorders such as attention-deficit/hyperactivity disorder (ADHD).
If methylphenidate shows an effect, the prospects are important for this patient group, since methylphenidate may then be included as part of the treatment of brain tumor-related fatigue.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Methylphenidate (MPH)Drug
10 mg methylphenidate tablets with a scoreline. Tablets will be administered orally.
For children aged 6-12, a daily dose of 5 mg x 2 will be administered during the first week with an increase in dose to 10 mg x 2 in the second week. For adolescents and adults above 12 years of age, the same starting dose will be used as for children, with weekly incremental increases up to a maximum of 15 mg x 2 daily in the third week. In case of potential toxicity events during study, dosage of methylphenidate can be modified according to protocol.
PlaceboDrug
10 mg methylphenidate-matched placebo tablets with a scoreline. Tablets will be administered orally.
Dosage will follow the exact same principles as for the study drug (methylphenidate).
| Study group | Role | What they receive |
|---|---|---|
| Methylphenidate, Then Placebo | Experimental | Patients will receive treatment with methylphenidate tablets for 6 weeks, and then cross over to treatment with methylphenidate-matched placebo tablets for an additional 6 weeks. A four week wash out period is incorporated between treatments. Receives: Drug: Methylphenidate (MPH); Drug: Placebo |

Clinical summary

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Methylphenidate (MPH) in people with Brain Tumor, Pediatric and Cancer-related Fatigue, run by Odense University Hospital at 4 sites in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 3 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Sebastian W Most-Mottelson, MD, PhD Student (+45 21567257, sebastian.wenzel.most-mottelson@rsyd.dk), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
PedsQL Multidimensional Fatigue Scale (MFS) (time frame: At baseline, at Week 6, Week 16, and Week 20 (follow-up).). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2026; AzTrials last refreshed its copy on 8 Nov 2026.
