What is the Origin of Investigational New Drug?

This is a legal and regulatory term that originates specifically from the United States Food and Drug Administration (FDA) regulatory framework. It designates a substance as investigational because it is still under scientific study and new drug because it has not yet received final authorization for widespread commercial use.

What is the Mechanism of Investigational New Drug?

The IND mechanism is initiated when a pharmaceutical sponsor submits a comprehensive application to the FDA detailing the drug's chemical composition, manufacturing and quality control information, and all available results from preclinical animal toxicology and pharmacology studies. The core function of the IND is to protect the rights and safety of the human subjects who volunteer for clinical trials while simultaneously ensuring that the proposed research plan is scientifically rigorous and ethically sound.

Investigational New Drug

Meaning

An Investigational New Drug (IND) is a pharmaceutical compound or biological product that has not yet been formally approved for general use by a national regulatory authority, such as the Food and Drug Administration (FDA), but is authorized for use in controlled clinical trials on human subjects. This regulatory status grants the sponsor permission to ship the drug across state lines for the purpose of gathering the essential safety and efficacy data required for eventual market approval. The IND application is the mandatory first step in the formal, multi-phased drug development and approval process.
