Brain Tumors

Exciting Development in the Treatment of Rare Brain Tumors


A recent study published in the Journal of Clinical Oncology has shed light on a promising new potential treatment for patients suffering from rare and incurable brain tumors. The research, spearheaded by Karan Dixit, MD, an assistant professor in the Department of Neurology at Northwestern University, has shown encouraging results for a subset of patients facing aggressive diffuse midline gliomas, a rare type of brain tumor.

These gliomas, which are diagnosed in around 800 individuals each year in the U.S., pose a significant clinical challenge due to their location in the brain and their resistance to traditional treatments. Typically caused by a H3 K27M mutation, these tumors have proven difficult to manage, with radiation being the only somewhat effective therapy currently available. However, even with radiation, the prognosis for patients with this subtype of brain tumor is grim, with over 70% succumbing to the disease, as per the National Institutes of Health.

The study focused on evaluating the efficacy of dordaviprone, an investigational drug designed to target the specific protein present in tumors with the H3 K27M mutation. Analyzing data from five prior clinical trials involving 50 patients with these difficult-to-treat gliomas, the researchers found that 30% of the participants responded positively to the drug. The most commonly reported side effect was fatigue, indicating that the drug was generally well-tolerated.

Dr. Dixit emphasized the significance of these findings, stating that dordaviprone represents a potential breakthrough in managing recurrent histone-mutated gliomas. The drug’s ability to elicit a substantial response in a subset of patients who had limited treatment options before marks a significant advancement in the field. Despite the modest response rate of 20% to 30%, for patients who previously had no viable options, this represents a ray of hope.

Building on these promising results, Dr. Dixit and his team are preparing to launch a new trial at Northwestern Medicine hospitals to further explore the drug’s effectiveness in newly diagnosed patients. As the sole site in Illinois conducting this trial, they are eager to assess the drug’s potential in a broader patient population and potentially expand treatment options for those grappling with these challenging brain tumors.

This research stands as a testament to the relentless pursuit of innovative therapies for rare and aggressive forms of cancer, offering hope to patients and healthcare providers alike. The development of targeted treatments like dordaviprone underscores the transformative impact that precision medicine can have in addressing unmet medical needs and improving outcomes for individuals battling complex diseases.
