Achaogen got some anticipated good news Tuesday with an FDA nod for its high-powered antibiotic Zemdri, but it wasn't an unqualified win. Zemdri will make its debut as a treatment for drug-resistant urinary tract infections with a black-box warning, and it missed out on a second use—bloodstream infections—it had hoped to win this first go-round.
