In January 2020, the company announced its acquisition of Dermira for $1.1 billion, gaining control of two key assets, among others; lebrikizumab and glycopyrronium cloth used to treat hyperhidrosis. In June, the company announced it had begun the world's first study of a potential monoclonal antibody treatment for COVID-19, with a Phase 1 trial of LY-CoV555, in collaboration with AbCellera. On October 7, 2020, Eli Lilly announced that its cocktail was effective and that it had filed with the Food and Drug Administration for an emergency use authorization (EUA). This was the same day that rival company Regeneron also filed for an EUA for its own monoclonal antibody treatment. In October, Eli Lilly announced it would acquire Disarm Therapeutics at its experimental treatments for axonal degeneration, via SARM1 inhibitors, for $135 million (plus a further $1.225 billion based on regulatory and commercial milestones). In October, Eli Lilly announced that the National Institutes of Health (NIH) ACTIV-3 clinical trial evaluating its monoclonal antibody, bamlanivimab (LYCoV555), found that bamlanivimab was not effective in treating people hospitalized with COVID-19. Other studies, including the NIH ACTIV-2 trial and its own BLAZE-1 trial, will continue to evaluate bamlanivimab. In November, the U.S. Food and Drug Administration issued an emergency use authorization (EUA) for the investigational monoclonal antibody therapy bamlanivimab for the treatment of mild-to-moderate COVID-19 in adult and pediatric patients. In December, Lilly announced it would acquire Prevail Therapeutics Inc for $1 billion, boosting its pipeline in neurodegenerative disease gene therapies.
