Signage is seen outside of the Food and Drug Administration (FDA) headquarters in White Oak, Maryland, U.S., August 29, 2020. The U.S. Food and Drug Administration (FDA) has not yet confirmed when the advisory panel would meet, they added. Shares of Bristol Myers Squibb fell more than 2% and those of 2seventy bio slid nearly 20% in early morning trade. The therapy was originally co-developed by bluebird bio (BLUE.O) but following its spin-off in 2021 became part of 2seventy's portfolio. Bristol Myers and 2seventy bio, however, have faced manufacturing constraints, and a month-long planned maintenance shutdown of one of Abecma's manufacturing facility in June had also negatively impacted sales.
