This type of study is called a "Phase I study". Its purpose is to determine the side effects of the two medicines listed in this study when given together with whole brain radiation, and the highest dose of valproic acid that can be given together with temozolomide and whole brain radiation. We will also study the drug combination's effectiveness in treating cancer. While both of these drugs and whole brain radiation have been used in people for many years, they have never been combined for the purpose of treating patients with cancer.
At the start of the study, patients will be informed which dose level they will be treated with. On day 1, patients will have a physical exam and several blood draws including draws to measure the level of valproic acid in their body. Patients will start your whole brain radiation and also at the same time start the valproic acid and temozolomide pills. Patients will be asked to take the valproic acid pills every 12 hours and the temozolomide pills once daily. Patients will not need to come to the center for that but will need to come to the center to receive you whole brain radiation for 3 weeks (on weekdays, excluding holidays). Radiation therapy will not be administered on weekends but patients will still take their pills for the whole 3 weeks from starting the radiation.
Patients will have to come back for a study visit weekly for the 6 months. Two more visits are also required: approximately 6 weeks and 10 weeks from starting the treatment. Patients will be asked about any old or new symptoms to determine if adjustment in the pill dose is required.
Every study visit except the last one will include blood draws. These will evaluate blood counts, blood chemistry and also measure the level of valproic acid in your body. The Mini Mental Status examination described above will be repeated in every visit.

Background: - Radiation therapy with temozolomide (an anti-cancer drug) is standard therapy for treating brain tumors called glioblastomas. - The drug valproic acid, cur...
The study investigates valproic acid added to radiation and temozolomide therapy (standard of care) for progressive or recurrent pediatric brain tumors.
Currently, there are few effective treatments for your type of aggressive brain tumors. Surgery and radiation can generally slow down these aggressive brain tumors, but in the majority of ...
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs such as temozolomide may make the tumor cells more sensitive to radiation therapy. Combining temozolomide ...

Evaluate the toxicity and efficacy of adjuvant temozolomide (TMZ) and irinotecan (CPT-11) for 12 months following concurrent chemo-radiation in newly diagnosed glioblastoma (GBM).
Patients with history of brain radiotherapy can experience acute "stroke-like" syndromes related to the delayed effects of brain radiation, including "Stroke-like Migraine Attacks after Radiation Ther...
Glioblastoma is the most common and aggressive primitive brain tumor in adults. Temozolomide (TMZ) administered daily with radiation therapy, followed by adjuvant TMZ has become the standard treatment...
A fatty acid with anticonvulsant properties used in the treatment of epilepsy. The mechanisms of its therapeutic actions are not well understood. It may act by increasing GAMMA-AMINOBUTYRIC ACID levels in the brain or by altering the properties of voltage dependent sodium channels.
Tissue NECROSIS in any area of the brain, including the CEREBRAL HEMISPHERES, the CEREBELLUM, and the BRAIN STEM. Brain infarction is the result of a cascade of events initiated by inadequate blood flow through the brain that is followed by HYPOXIA and HYPOGLYCEMIA in brain tissue. Damage may be temporary, permanent, selective or pan-necrosis.
Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.
Bleeding within the brain as a result of penetrating and nonpenetrating CRANIOCEREBRAL TRAUMA. Traumatically induced hemorrhages may occur in any area of the brain, including the CEREBRUM; BRAIN STEM (see BRAIN STEM HEMORRHAGE, TRAUMATIC); and CEREBELLUM.
A condition characterized by long-standing brain dysfunction or damage, usually of three months duration or longer. Potential etiologies include BRAIN INFARCTION; certain NEURODEGENERATIVE DISORDERS; CRANIOCEREBRAL TRAUMA; ANOXIA, BRAIN; ENCEPHALITIS; certain NEUROTOXICITY SYNDROMES; metabolic disorders (see BRAIN DISEASES, METABOLIC); and other conditions.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
