investigative new drug
LowTechnical / Professional
Definition
Meaning
A new pharmaceutical compound approved for testing in human clinical trials but not yet approved for general marketing or therapeutic use.
The legal and regulatory status of a novel compound (IND) that allows it to be shipped and administered to humans in a clinical trial setting, following preclinical studies. It encompasses the substance itself, its proposed trial protocol, and the data package submitted to regulatory authorities (e.g., FDA).
Linguistics
Semantic Notes
Strictly a regulatory term used in medicine, pharmacology, and law. It is a compound noun phrase, not an adjective phrase describing a drug. Often used in its abbreviated form 'IND' within the relevant fields. It is a specific category, not synonymous with 'experimental drug' (a more general term).
Dialectal Variation
British vs American Usage
Differences
The term is identically defined and used in US and UK regulatory and clinical contexts. The primary difference is the regulatory body to which the IND application is submitted (e.g., FDA in the US, MHRA in the UK). The abbreviation 'IND' is standard in both varieties.
Connotations
Neutral, legal, and procedural in both varieties. Conveys official permission for a specific phase of research.
Frequency
Equally low-frequency and highly specific to the pharmaceutical and medical research industries in both regions.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation that suggests the drug itself is performing an investigation. The phrase 'investigative' refers to the stage/purpose of its use.
- Distinguish from general Russian terms for 'experimental drug' (экспериментальный препарат) – an IND is a specific regulatory category.
Common Mistakes
- Using it as an adjective (e.g., 'an investigative new drug study' is ambiguous; better: 'a study under an IND' or 'an IND study').
- Confusing it with 'investigational drug', which is a near-synonym but less formal/legal.
- Thinking it refers to a drug used in criminal investigations.
