Amid a slow quarter for approvals, Alnylam got its fifth approval in as many years with Amvuttra (vutrisiran), a next-generation RNA interference (RNAi) drug for the rare disease hereditary transthyretin-mediated (hATTR) amyloidosis. It offers more convenient subcutaneous delivery than the company’s own drug for the same indication, Onpattro (patisiran), which requires frequent infusions. Also notable is Bristol Myers Squibb’s first-in-class therapy for hypertrophic cardiomyopathy, Camzyos (mavacamten), which is a unique disease-modifying intervention for this indication. Garnering the most attention, however, was Lilly’s drug Olumiant (baricitinib), the first systemic drug for hair loss, which adds to an existing set of indications (including COVID-19) for the Janus kinase/signal transducer and activator of transcription (JAK/STAT) inhibitor. In the coming months, the US Food and Drug Administration will assess a slew of monoclonal antibodies — mostly, but not exclusively, for cancer indications.
