Alnylam Pharmaceuticals ALNY announced that the FDA has accepted its supplemental new drug application (sNDA) seeking the label expansion of Amvuttra (vutrisiran) for review to treat ATTR amyloidosis with cardiomyopathy (ATTR-CM).

The FDA has accepted Alnylam’s supplemental New Drug Application for Amvuttra on the heels of BridgeBio’s Attruby nod, potentially giving Pfizer’s tafamidis franchise another competitor.
