0739 ET - The FDA's approval of Alnylam's Amvuttra in the cardiomyopathy of transthyretin-mediated amyloidosis, or ATTR-CM, puts the drug well on track to achieving mega blockbuster status, Citi says. Analysts David Lebowitz and Ike Lee say the drug's label was clean and overall in line with their expectations, which they say will enable strong uptake. The green light makes Amvuttra the only U.S. drug approved to address both cardiomyopathy and polyneuropathy manifestations of ATTR amyloidosis, a factor Citi says could resonate with practitioners. Alnylam up 4.5% premarket to $265. (colin.kellaher@wsj.com)
