About Clinical Research

What is a clinical study?

A clinical study (such as LIDS) involves research that is intended to add to medical knowledge related to the treatment of diseases or conditions (such as TED). Clinical studies enroll volunteers (also called participants) to help researchers compare an investigational drug to a placebo that contains no active ingredients.

What is an investigational drug?

An investigational (or study) drug is a drug that is being tested in clinical studies. Linsitinib is the oral investigational drug being studied in LIDS. Investigational drugs may or may not be approved by the government health agency. However, every investigational drug must be reviewed, approved, and monitored by an ethics committee for testing in clinical study participants.
