This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in mice, not in people with brain tumors.
The short version
An experimental drug cleared brain tumors in half the mice that got it, but this was a mouse study.
What was studied. Researchers tested a drug called APG157DS in mice 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, a brain tumor. The drug is already being tested in people for other cancers, including head and neck cancer.
What they found. Tumors went away and stayed away in 50% of the mice treated with the drug. All the mice that did not get the drug became too sick within 42 days. The drug also seemed to switch immune cells inside the tumor so they attacked it, and it brought in more tumor-fighting immune cells.
What this means, and what it doesn't
What it could mean: This gives researchers a reason to study this drug for brain tumors in people. Right now it is not a treatment a patient with a brain tumor can get.
What it doesn't mean: This does not mean the drug works for people with brain tumors. It was tested only in mice, and many drugs that help mice do not help people. This is early animal research, and it is years away from everyday care. It is not a cure and not a promise of one.
