The effects of colchicine on lipoprotein(a)- and oxidized phospholipid-associated cardiovascular disease risk

  • Secondary analysis of the LoDoCo2 randomised trial
  • biomarker subpopulation

Authors' conclusion

In patients with CCS, colchicine reduces cardiovascular disease risk in those with and without elevated Lp(a) but absolute benefits appeared higher in those with Lp(a) ≥ 125 nmol/L. Patients with higher levels of OxPL-apoB experienced greater benefit of colchicine, suggesting that colchicine may be more effective in subjects with heightened oxidation-driven inflammation.

Study context

Population
Patients with chronic coronary syndrome (CCS) in the LoDoCo2 biomarker populationbiomarker population
Participants
1,777 patients
Comparison
Colchicine vs placebo, by Lp and OxPL levels
Primary endpoint
MI, ischaemic stroke or ischaemia-driven revascularization, by biomarker levels

Primary result

As reported in the abstract

Colchicine effect by Lp(a) and OxPL subgroups

Consistent risk reduction by colchicine with Lp(a) <125 and ≥125 nmol/L and highest vs lowest OxPL-apo(a) tertile

Pinteraction = 0.92 and 0.66

Absolute risk reduction, Lp(a) ≥125 vs <125 nmol/L

4.4% vs. 2.4%

Treatment interaction, highest vs lowest OxPL-apoB tertile

Pinteraction = 0.04

Further findings

Lp(a), OxPL-apo(a) and OxPL-apoB levels

Similar between colchicine and placebo
