What Is a Best-in-Class Drug?
A best-in-class drug is a therapy that is believed to perform better than other drugs in the same class on key dimensions such as efficacy, safety, convenience, or overall patient experience. In biotech, the term is important because it signals differentiation in a competitive market. A first-in-class drug may be novel, but a best-in-class drug is the one that could become the preferred option within an existing category.
