ONC206 treatment for children with diffuse midline glioma and other recurrent malignant brain tumors

Phase 0/1 trial of ONC206 - a novel imipridone for children with diffuse midline gliomas and recurrent malignant brain tumors

NIH-funded research University of California, San Francisco · NIH-11410957

An oral drug called ONC206 that can reach the brain is being given to children with diffuse midline gliomas and other recurrent malignant brain tumors to check safety and look for early signs of benefit.

What this research studies

If you join, doctors will give ONC206 by mouth and start with very low doses that are increased carefully to find a safe dose for children. The team will do blood tests to measure drug levels, regular scans to watch the tumor, and monitor for side effects. Some patients will get ONC206 alone and others will get it together with radiation depending on whether the tumor is newly diagnosed or recurrent. Researchers will also study tumor and blood markers linked to the drug's action on a mitochondrial protein called ClpP to see who might respond.

Who could benefit from this research

Good fit: Children with diffuse midline gliomas or other recurrent malignant pediatric brain tumors who meet the trial's eligibility criteria and can travel to the study site may be eligible.

Not a fit: Patients for whom the tumor does not express the drug's target or who are medically unfit for the trial treatments may not receive benefit from participation.

Why it matters

Potential benefit: If successful, ONC206 could offer a new treatment option that reaches the brain and may slow tumor growth or extend survival for children with these aggressive brain tumors.

How similar studies have performed: Related drugs in the imipridone class have shown early signals of activity in brain tumors, but ONC206 is a newer compound being tested in humans.
