The US Food and Drug Administration (FDA) picked up the pace of drug registrations after a sluggish first quarter. Many were accelerated approvals for cancer indications, including two small molecules — Incyte’s Pemazyre and Novartis’s Tabrecta — approved with companion diagnostics from Foundation Medicine. The agency halted two adeno-associated virus (AAV) gene therapy trials, from Audentes and Sarepta, for safety reasons; next quarter, the European Medicines Agency (EMA) will consider AAV gene therapies from Biomarin and PTC Therapeutics for hemophilia and aromatic l-amino acid decarboxylase (AADC) deficiency, respectively. A small interfering RNA (siRNA) oligonucleotide therapy for hypercholesterolemia from Novartis (The Medicines Company) also will be under evaluation. Several companies reported clinical results from drugs repurposed for COVID-19, with Gilead and Kiniksa reporting preliminary data showing improvements in duration of illness and certain outcomes for Veklury (remdesivir) and mavrilimumab, respectively.

Historic US regulatory approvals by drug class

Despite the pandemic, the rate of drug approval looks remarkably similar to previous years’.
