The document discusses several clinical trials being conducted by Global Clinical Trials to research treatments for various conditions. It summarizes trials for Alzheimer's disease, adolescent schizophrenia, irritable bowel syndrome, and Tardive Dyskinesia. The Alzheimer's trial is investigating whether a drug called azeliragon can slow progression of mild Alzheimer's. The adolescent schizophrenia trial aims to determine if the drug lurasidone is safe and effective for teens with schizophrenia. Trials are also working to develop treatments for IBS and Tardive Dyskinesia, two conditions that currently lack effective treatment options. Participation in these studies helps advance research that may lead to improved treatment or cures for these diseases.
