Preliminary Efficacy and Safety Study of ST101 in Alzheimer's Disease

Alzheimer's disease (AD) is a progressive and fatal neurological illness. It produces changes in the brain that include loss of cells and accumulation of abnormal protein deposits. Initial symptoms are cognitive, with deficiencies in short-term memory the most common symptom. As the disease progresses so does the severity of cognitive deficiency. Loss of speech and immobility occur in the terminal stages There is no cure for AD and no marketed treatment that modifies the underlying disease process. Available therapies improve some symptoms of AD by increasing brain concentrations of molecules involved in cognition. ST101 differs from marketed therapies in that it has demonstrated two actions in animal research testing. It improves cognition and it also reduces the accumulation of abnormal protein deposits in the brain. These two properties suggest that ST101 may be a promising agent for the treatment of AD. This study is designed as a preliminary dose exploration/proof-of-concept investigation of the ability of ST101 to improve cognition during 12 weeks of administration.
