Two separate late stage drug trials reported 7 November 2026 found experimental cardiovascular medications successfully reached their intended biological targets but failed to reduce adverse event rates.

Novo Nordisk's ziltivekimab lowered IL-6 levels and reduced cardiac inflammation in the ZEUS phase 3 trial, but showed no benefit over placebo for cardiovascular event outcomes. [^1] [^2] Two publishers carried this result.

Novartis' experimental drug pelacarsen reduced Lp(a) blood levels by 78% across 8300 patients followed over 4.7 years. No cardiovascular event benefit was recorded for the treatment. [^3]

It appears that modifying these individual blood markers alone did not translate to the clinical outcomes researchers had sought.
