The short version
This trial is testing whether the time of day you take your temozolomide pill can be set, and what that is like for people with glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary.
Who this trial is for. This trial is for adults with glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary who are taking temozolomide, a chemotherapy pill often given after brain surgery and radiation. Participants are randomly placed in a morning group or an evening group, take their pill at that time, write it down in a pill diary, and wear a wrist device during their first cycle.
Where it stands. This trial has not reported results. Its main question is whether people with glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary can stick to taking temozolomide at a set time of day. It is also looking at how many people join, safety, quality of life, the body's timing of the drug, and changes in people's condition over time. The answers are not in yet.
What this means, and what it doesn't
What it could mean: Right now this does not change how temozolomide is taken. The study is meant to help researchers plan a larger trial later. If you have glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary and are taking temozolomide, you could ask your care team whether a trial like this is worth looking into for you.
What it doesn't mean: This does not mean that taking the pill in the morning or the evening is better. A trial is a test, not a proven treatment. Joining a trial is not a guarantee that you will be helped. This is not a promise of a cure.
