The Pharmaceutical Industry in 2024: An Analysis of the FDA Drug Approvals from the Perspective of Molecules

The U.S. Food and Drug Administration (FDA) has authorized 50 new drugs in 2024, which matches the average figure for recent years (2018–2023). The approval of 13 monoclonal antibodies (mAbs) sets a new record, with these molecules accounting for more than 25% of all drugs authorized this year. Three proteins have been added to the list of biologics, and with the inclusion of four TIDES (two oligonucleotides and two peptides), only one in three approved drugs this year is a small molecule. As of 2023, no antibody-drug conjugates (ADCs) have reached the market this year. Two deuterated drugs have been approved, bringing the total approvals for this class of compounds to four. This year saw the authorization of two more PEGylated drugs—both peptides—highlighting a renewed interest in this strategy for extending drug half-life, despite the setback caused by the withdrawal of peginesatide from the market in 2014 due to adverse side effects. N-aromatic heterocycles and fluorine atoms are present in two-thirds of all the small molecules approved this year. Herein, the 50 new drugs authorized by the FDA in 2024 are analyzed exclusively on the basis of their chemical structure. They are classified as the following: biologics (antibodies, proteins), TIDES (oligonucleotides and peptides), combined drugs, natural products, F-containing molecules, nitrogen aromatic heterocycles, aromatic compounds, and other small molecules.
