Iron Horse Diagnostics, Inc. is a molecular diagnostic company focused on the development and commercialization of novel tests to support the diagnosis and management of amyotrophic lateral sclerosis (ALS), traumatic brain injury (TBI), and other neurological diseases. The firm has developed and validated assays to measure protein-based signatures of disease. The company is developing diagnostics for ALS based on cerebrospinal fluid samples. In addition, the company is researching a blood-based diagnostic for ALS, with additional prognostic assays for ALS that can be used to monitor disease progression and test the effectiveness of drugs in clinical trials. Follow-up blood-based diagnostic assays will be for TBI and neuronal injury. ALS is currently clinically diagnosed by ruling out all other diseases that may cause symptoms similar to those presented by the patient. Iron Horse is developing the first diagnostic test for ALS that will rapidly determine if someone has the disease. Iron Horse is also developing markers of disease progression that will be useful to monitor disease progression and drug treatments during clinical trials.
