- Tested in people
This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in lab cells and in mice.
The short version
Scientists built a drug that aims an immune trigger straight at glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary cells, and it worked in mice.
What was studied. Researchers tested a lab-made drug called RICIA on human and mouse glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary cells that carry a marker called EGFRvIII. They also tested it in mice with these tumors.
What they found. The drug got inside the tumor cells through the EGFRvIII marker and set off an immune alarm. It changed the immune cells around the tumor from calm to active, and brought in more tumor-killing T cells. Mice lived longer, and in a number of cases the tumor cleared for a long time.
What this means, and what it doesn't
What it could mean: Aiming an immune trigger right at tumor cells may be one way to fight this kind of glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary. It is a reason to keep studying this approach.
What it doesn't mean: This does not mean a new treatment is close. The work was done in cells in the lab and in mice, not in people. Many things that help mice do not help people. This is not a promise of a cure, and no patient can get this today.
