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 Results may not be published yet.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

Summary

This pilot study tests whether an energy-restricted ketogenic diet (ERKD) can help control glioblastoma, an aggressive brain cancer. Sixteen adults with newly diagnosed glioblastoma will follow the diet while receiving standard radiation and chemotherapy. The goal is to see if the diet can shrink tumors or stop them from growing, and to learn about any side effects.

What this could mean

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

Active substance
energy-restricted ketogenic diet
What this could lead to
If it works, this could point toward a dietary approach to help control glioblastoma growth alongside standard treatments.
What could go wrong
This is a very small pilot study with only 16 people, so results may not apply widely. The diet is strict and may be hard to follow, and it's unclear if it will actually shrink tumors or improve survival.

An estimate. End dates often move.

Lead sponsor

Other sponsor

* Inclusion Criteria: * Adult subjects over age 18 with biopsy proven GBM diagnosis * Measurable disease after standard therapies * Eastern Cancer Oncology Group performance status \< or =2; and * Life expectancy \>3 months. Exclusion Criteria: * Diagnosis of diabetes mellitus that is being treated by medication * Concomitant use of glucocorticosteroids * Cholecystectomy within 1 year prior to study entry * Inability to adhere to or tolerate dietary protocol * Active malignancy other than primary brain tumor requiring therapy * Participation in an investigational study within 2 weeks prior to study entry; Major co-morbidities such as liver, kidney or heart failure that in the judgment of the investigators would disqualify the subject from the trial * Pregnancy * Inability to give informed consent
