Clinical Trial Pipeline

The NDC directory covers drugs that are already approved and marketed. This section tracks what is still in testing — by therapeutic area, phase and how the treatment is given.

Phase 3 — closest to approval

Large comparative studies, typically 1–3 years from an FDA decision. This is where tomorrow's NDC codes come from.

Phase 2 — in development

Mid-size studies testing whether the treatment actually works for the condition, usually 3–5 years out.

Phase 1 — early research

First-in-human safety and dosing work. Long-term, but every approved drug started here.

Browse the pipeline by therapeutic area

Each area maps to the same pharmacologic classes used in the NDC directory, so you can move between an approved drug and what is coming next.

Already approved? Look up the NDC

Once a treatment is marketed it gets a National Drug Code, a J-Code and a CPT administration code — all searchable in the directory.
