The secondary analysis of the CARDIOTTRansform Phase 3 trial reveals that failure to adequately power and stratify for background transthyretin stabilizer therapy diluted the apparent efficacy of eplontersen, highlighting the need for trial designs to treat concomitant therapies as key treatment modifiers rather than background noise.
