Shares of Eli Lilly soared Thursday morning after the pharmaceutical giant announced a clinical trial of its once-daily weight loss pill, orforglipron, demonstrated effectiveness consistent with other injectable GLP-1 weight loss drugs, such as Lilly’s Mounjaro and Novo Nordisk’s Ozempic.

Savvy pharma-stock investors know that an oral GLP-1 drug from Novo Nordisk called Rybelsus has been on the market as a diabetes treatment since 2019. It's an orally available version of semaglutide, which is the same active ingredient in Ozempic and Wegovy.
