Intra-arterial Chemotherapy for the Treatment of Progressive Diffuse Intrinsic Pontine Gliomas

Please be advised that while other intra-arterial delivery methods may be offered for this disease, this particular trial was only available at Johns Hopkins.

This trial is currently closed for analysis. A diffuse intrinsic pontine glioma (DIPG) is a type of tumor that grows in the pons of the brainstem. The pons is located at the base of the brain where it connects to the spinal cord. These tumors are difficult to treat because they grow within the normal brain tissue. This procedure involves administering melphalan hydrochloride, a chemotherapy agent, directly into the arteries that provide blood to this tumor. Delivering the chemotherapy through these arteries helps to the focus the chemotherapy agent directly on the tumor. This increases the dosage that the tumor receives and decreases the toxic effects of chemotherapy on the rest of the body.

Our interdisciplinary team consists of Monica Pearl, M.D., an interventional neuroradiologist who performs the procedure, Kenneth Cohen, M.D. and Eric Raabe, M.D., from the Department of Pediatric Oncology and Stephanie Terezakis, M.D. from the Department of Radiation Oncology.

Dr. Monica Pearl is a member of the Core Steering Group for the Children’s Brain Tumour Drug Delivery Consortium, an international, multidisciplinary network of clinicians and researchers dedicated to developing drug delivery systems for children with brain tumors (@cbtddc on Twitter). This novel pediatric brain tumor drug delivery consortium offers unparalleled opportunities for dialogue exchange, resource sharing and building research collaborations across the globe. Find out more about their mission and get involved to accelerate progress for children with brain tumors.

How is intra-arterial chemotherapy different from systemic chemotherapy?

Systemic chemotherapy involves injecting anti-cancer medications into a vein or giving them by mouth. This exposes the entire body to significant doses of chemotherapy, which can make the patient sick as it fights the cancer. Intra-arterial chemotherapy delivers the anti-cancer medication directly to the tumor via the vertebral artery, which supplies the tumor, thereby transforming the treatment from systemic (delivered to the whole body) to local chemotherapy (delivered directly to the tumor) and limits the complications and adverse effects of chemotherapy.
