BREAKTHROUGH STEM CELL STUDY: Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Researchers hope to train stem cells into becoming specific cells so that those specialized cells can be used to regenerate and repair diseased or damaged tissues in people. Both polypeptide growth factors and stem cell populations from bone marrow and umbilical cord blood hold promise as treatments to enhance neurologic recovery after a stroke. The ALD-401 trial is a phase 2 study with a phase 1 safety cohort testing ALD-401 stem cells derived from autologous bone marrow delivered via intracarotid infusion in subjects with ischemic stroke. All study assessments are blinded. This trial is the first trial in the United States and in the world to study the infusion of stem cells into the human brain.
