Overview
Brief Summary
There is evidence suggesting that stem cells harvested from the bone marrow and transplanted into the brain may be effective in slowing down the progression of parkinsonism. Mesenchymal stem cells are able to produce growth factors that provide support to diseased nervous cells.
In this study mesenchymal stem cells will be harvested from the bone marrow, cultivated in a test tube so that they multiply and then infused into the arteries that supply blood to the brain in 20 patients suffering from a rare form of parkinsonism, Progressive Supranuclear Palsy. Each patient will undergo two infusions, one with the stem cells and one without, at an interval of 6 months. The sequence of the two infusions will be assigned randomly; patients and assessors will not know the sequence (double-blind). Patients will be followed-up for up to 1 year after the last infusion, with regular assessments to assess safety, efficacy on motor and cognitive functions, and effects on the brain by neuroimaging techniques.
The study has a preliminary phase with 5 patients all given stem cell therapy alone, designed to assess safety
