A cou­ple months ahead of its PDU­FA date, Bris­tol My­ers rolls out long-term da­ta for mava­camten

It’s al­most time for the FDA to make a de­ci­sion on mava­camten, the myosin in­hibitor at the cen­ter of Bris­tol My­ers Squibb’s $13 bil­lion MyoKar­dia buy­out. With a Jan. 28 PDU­FA date loom­ing, the phar­ma gi­ant is now tak­ing the wraps off some long-term da­ta it hopes will bol­ster the drug’s case for ap­proval.

Heart pa­tients who re­ceived mava­camten in a co­hort of the long-term MA­VA-LTE study saw sig­nif­i­cant re­duc­tions in me­di­an lev­els of a hor­mone called NT-proB­NP (58% at week 24 and 67% at week 48), Bris­tol My­ers re­port­ed at this year’s Amer­i­can Heart As­so­ci­a­tion con­fer­ence. High­er than nor­mal NT-proB­NP lev­els are in­dica­tive of heart fail­ure.
