💬In plain words
What the trial is, and whether it could suit you
This phase I trial tests the safety, side effects, and best dose of allogenic adipose-derived mesenchymal stem cells (AMSCs) in treating patients with glioblastoma or astrocytoma that has come back (recurrent) who are undergoing brain surgery (craniotomy). Glioblastoma is the most common and most aggressive form of primary and malignant tumor of the brain. Currently, the standard of care for this disease includes surgical resection, followed by radiation with chemotherapy and tumor treating fields. Despite this aggressive therapy, the survival after finishing treatment remains low and the disease often reoccurs. Unfortunately, the available therapy options for recurrent glioblastoma are minimal and do not have a great effect on survival. AMSCs are found in body fat and when separated from the fat, are delivered into the surgical cavity at the time of surgery. When in direct contact with
