What was the first drug approved with a companion diagnostic?

Is a companion diagnostic an IVD?

An IVD companion diagnostic is an in vitro diagnostic (IVD) medical device which provides information that is essential for the safe and effective use of a corresponding medicine or biological.

Are companion diagnostics combination products?

Combination products, including companion diagnostics, are a marriage of different scientific areas involving complex technology. Each part of the product is governed by a different regulatory pathway with different requirements throughout the product development lifecycle.

Do diagnostic tests require FDA approval?

In the United States, the development and marketing of commercial tests are regulated by the U.S. Food and Drug Administration (FDA). They are considered “medical devices” and, specifically, “in vitro diagnostic devices (IVD).” As such, they must be evaluated and approved by the FDA.
