Acute Lymphatic Leukemia clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Longitudinal Investigation of Hippocampal Function and Morphology in Acute Lymphatic Leukemia (ALL) Patients Treated With Chemotherapy

HIF-ALL

Start date: February 2010
Phase: N/A
Study type: Observational

There are two regions in the adult brain that exhibit neuronal stem and progenitor cells, generating new neurons postnatally and throughout adulthood. One is the so called subventricular zone the other is the dentate gyrus of the hippocampus. Adult neurogenesis is a physiological process representing an important functional impact for certain brain areas, especially the hippocampus. The hippocampal formation plays an important role in long-term memory and spatial navigation. Inhibition of adult neurogenesis in mice by chemotherapy or radiation is followed by significant deficits in hippocampal memory functions while hippocampus-independent memory is unaffected. Clinical trials had shown that chemotherapy and brain radiation lead to cognitive dysfunction. However, the exact mechanisms underlying this phenomenon are still unidentified. The aim of our study is to investigate, whether the inhibition of adult neural stem cell proliferation in the hippocampus by intrathecal chemotherapy and/or cerebral radiation is responsible for treatment induced memory deficits. We will investigate patients suffering from acute lymphatic leukaemia (ALL) that receive prophylactic intrathecal chemotherapy and brain irradiation. The study represents a longitudinal investigation including a virtual "humanized" version of the morris-water-maze to test hippocampus dependent spatial memory, as well as MR-imaging for morphological (volumetry) and biochemical (spectroscopy) data.
