NDA — What It Means in Clinical Trials
Plain English Definition
An NDA (New Drug Application) is the formal submission a drug company makes to the FDA to request approval to sell a new drug. The NDA includes all clinical trial data, safety information, manufacturing details, and proposed labeling. The FDA review of an NDA can take 6-12 months.
Why It Matters
When a drug company files an NDA, it means clinical trials are complete and the company believes it has enough evidence to win approval. If approved, the drug becomes available to the general public by prescription.
Example
You might read in the news: "Company X has submitted an NDA for Drug Y based on positive Phase 3 results." This means the drug could be approved within a year.
