J&J plans for capped, flexible dosing after four patient deaths in early study of actinium prostate cancer drug

An ex­per­i­men­tal prostate can­cer drug de­vel­oped by John­son & John­son that us­es a rare ra­dioac­tive par­ti­cle called ac­tini­um-225 led to three pa­tients see­ing their tu­mors shrink sub­stan­tial­ly, but four pa­tient deaths, ac­cord­ing to the first re­sults from an ear­ly-stage study.

The ther­a­py re­sult­ed in five cas­es of in­ter­sti­tial lung dis­ease, which is in­flam­ma­tion and scar­ring in the lung, and two of those cas­es were fa­tal. The two ad­di­tion­al pa­tient deaths were al­so con­sid­ered re­lat­ed to treat­ment — one pa­tient had res­pi­ra­to­ry fail­ure with Covid-19, and low blood pres­sure and a de­crease in ap­petite were list­ed as treat­ment-emer­gent ad­verse events for the oth­er pa­tient.
