Approvals rolled on, with some notable firsts: the first ever FDA-approved drug for Hutchison–Gilford progeria and European approval for a small-interfering RNA (siRNA) in a blockbuster indication—Novartis/Alnylam’s cholesterol-lowering Leqvio (inclisiran), targeting proprotein convertase subtilisin kexin type 9 (PCSK9). Another siRNA drug, Oxlumo (lumasiran) for hyperoxaluria, was also registered at the FDA. Several gene and cell-based therapies ran into problems, mainly due to manufacturing issues or an inability to inspect third-party manufacturing sites. In infectious disease, registrations came for two new Ebola monoclonal antibody (mAb) treatments, one a cocktail of three recombinant molecules and the other a mAb derived from the plasma of a survivor of the 2015 outbreak; interim reporting on COVID-19 trials is ramping up, with more to come in the coming quarters.

Oncology still leads in all stages of drug development, but infectious diseases and neurology pipelines are growing, a sign of the pandemic and aging populations.
