Plant­i­ng an­oth­er flag on Pfiz­er and Al­ny­lam's turf, As­traZeneca grabs amy­loi­do­sis drug from the biotech that in­vent­ed Aduhelm

As­traZeneca — or, more specif­i­cal­ly, its rare dis­ease sub­sidiary Alex­ion — is se­ri­ous about get­ting in­to AT­TR amy­loi­do­sis.

Just weeks af­ter li­cens­ing a late-stage an­ti­sense can­di­date from Io­n­is, As­traZeneca has struck an­oth­er deal to pick up a Phase Ib an­ti­body hit­ting the same tar­get, this time from Swiss biotech Neurim­mune.

The up­front from Alex­ion comes in at $30 mil­lion, with the po­ten­tial to add up to $730 mil­lion in mile­stones. Alex­ion is hop­ing the pro­gram would tack­le transthyretin amy­loid car­diomy­opa­thy, or AT­TR-CM, which is char­ac­ter­ized by car­diac buildup of tox­ic amy­loid fib­rils.
