NB005 in Combination with Radiation Therapy With or Without Temozolomide for the Treatment of High Grade Gliomas and Leptomeningeal Metastasis

Trial Status: active

This early phase I/phase I trial tests the safety, side effects, and best dose of NB005 in combination with radiation therapy, with or without temozolomide, in treating patients with high grade gliomas (HGGs) and leptomeningeal metastasis. HGG is a type of fast and uncontrollably growing brain tumor that starts in brain cells called glial cells and invades surrounding brain tissue, making it difficult to treat. Leptomeningeal metastasis are a serious problem that may occur in cancer in which tumor cells spread from the original (primary) tumor to the meninges (thin layers of tissue that cover and protect the brain and spinal cord). It can happen in many types of tumors. NB005 works by targeting deoxyribonucleic acid (DNA) repair in tumors and is often tested with other treatments, like radiation, to check if it's safe and effective. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Proton craniospinal irradiation (pCSI) is a type of radiation treatment that uses proton beams to treat the whole brain and spine. It helps target the tumor while protecting healthy parts of the body as much as possible. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells and slow down or stop tumor growth. Giving NB005 with radiation therapy, with or without temozolomide, may be a safe treatment for patients with HGGs and leptomeningeal metastasis.
