The US Food and Drug Administration (FDA) kept up its pace with nine approvals. Notable firsts include Tazverik for epithelial sarcoma (the first small-molecule inhibitor of the histone methyltransferase EZH2) and Tepezza for thyroid eye disease (the first approved monoclonal antibody (mAb) targeting insulin-like growth factor receptor; IGF-1R). Mesoblast’s mesenchymal stem cell therapy (remestemcel-L) for pediatric graft-versus-host disease and GlaxoSmithKline’s first-in-class small molecule HIV attachment inhibitor targeting glycoprotein 120 (gp120) come before the FDA next quarter. Clinical trial results of two oligonucleotide drugs showed a cholesterol-lowering antisense oligonucleotide drug and a small-interfering RNA (siRNA) drug gave improvements over statin alone. The COVID-19 pandemic is affecting the drug pipeline; Bristol-Myers Squibb’s Zeposia is among several drug launches delayed.

Historic US regulatory approvals by drug class

Biologics approvals held steady in 2019.

*New molecular entity (NME) class includes mainly small-molecule drugs, but also steroid, synthetic peptide, and mixed compounds, excluding new formulations. **Partial year to March 31.Source: BioMedTracker, a service of Sagient Research (http://www.biomedtracker.com).
