Key Steps to FDA Approval for a Therapeutic Drug

Key Steps to FDA Approval for a Therapeutic Drug

August 1, 2025 by investor

FDA approval is a lengthy and involved process with therapeutic drugs that startups must go through.

Here’s a list of the key steps to achieve FDA approval:

After basic research, the founder applies for an Investigational New Drug Application called an IND.

The founder takes the proposed therapeutic or drug through four phases of clinical trials.

Phase 1 is for safety testing. 

Phase 2 is for effectiveness.

Phase 3 focuses on additional safety testing to determine side effects.

Phase 4 focuses on additional efficacy tests.

After testing comes the New Drug Application or NDA.

The FDA reviews the NDA, including the clinical data and research, to determine approval.

There are fast-track paths for drugs that treat serious medical conditions that have no current solution.

There is also a breakthrough therapy path for drugs that show substantial improvement over the current solution.

For investing in therapeutic startups, consider the FDA pathway for the drug and where it currently resides on that pathway.
