Drug Hunter Team

We’ll be reviewing 2021’s novel FDA drug approvals in a series of articles, starting with this high-level overview of the small molecule drugs approved by the FDA in 2021. You can find Part 2 on First-in-Class Small Molecules here and the 2021 Large Molecules series here. Our deep dive on Small Molecule Oncology Approvals is also live.

together with Jen Huen, Vinicius Texeira, Naveed Yasin, Maria Koyioni, and Adrian Parodi

There were:

  • 50 novel drugs approved in 2021

  • 32 small molecules in this group (including peptides, excluding radiologics)

  • 16 large molecules

  • 27 “first-in-class” drugs

For small molecules, there were:

  • 9 in oncology

  • 5 in neurology

  • 5 for genetic conditions

  • 4 for infectious diseases

  • 3 in immunology

  • 2 in endocrinology

  • 1 in dermatology

  • 1 in hematology

  • 1 in cardiology

  • 1 in family medicine

Three of our favorite molecules are shown below:

Our complete, hi-res compilation of all 32 of the small molecule drugs with structures, drug targets and mechanisms of action, doses and routes of administration, and indication appears below. You can find past examples of our 2020 Small Molecule Approvals Poster and 2019 Small Molecule Approvals Poster online.
