Hs-CRP-Guided Colchicine Treatment Targets in Very-High-Risk Patients With Coronary Artery Disease After PCI (TARGET-CHD)

30 de octubre de 2026 actualizado por: Wenbin Zhang, Sir Run Run Shaw Hospital

Colchicine Titration Guided by Hs-CRP Targets on Cardiovascular Events in Very-High-Risk Coronary Heart Disease Patients After PCI: A Multicenter, Randomized, Open-Label, Noninferiority Trial

This multicenter, randomized, open-label, noninferiority trial will compare two high-sensitivity C-reactive protein (hs-CRP) target-guided colchicine strategies in 1,768 adults with very-high-risk coronary artery disease after percutaneous coronary intervention, LDL cholesterol ≤1.4 mmol/L, and residual inflammation (hs-CRP 2.0-10.0 mg/L). Participants will be assigned 1:1 to a standard target of 1.0 to <2.0 mg/L or an intensive target of <1.0 mg/L. Both groups will start colchicine 0.25 mg orally once daily, with dose adjustments guided by hs-CRP and tolerability. The primary outcome is the 18-month composite of cardiovascular death, nonfatal myocardial infarction, nonfatal ischemic stroke, or ischemia-driven revascularization. The noninferiority hypothesis compares the standard target strategy with the intensive target strategy, with a prespecified hazard-ratio margin of 1.30.

Descripción detallada

Adults with coronary artery disease after PCI who meet very-high-risk atherosclerotic cardiovascular disease criteria, have fasting LDL cholesterol ≤1.4 mmol/L within 1 month, and have fasting hs-CRP 2.0-10.0 mg/L within 7 days before enrollment will be randomized through a central system. Randomization is stratified by center, baseline hs-CRP (<5 vs ≥5 mg/L), and age (<65 vs ≥65 years). All participants continue standard coronary disease care and start colchicine 0.25 mg orally daily. At 1 month, the intensive group maintains the dose when hs-CRP is <1.0 mg/L or, if tolerated, increases to 0.5 mg daily otherwise. The standard group reduces to 0.25 mg every other day if hs-CRP is <1.0 mg/L, continues 0.25 mg daily if hs-CRP is 1.0 to <2.0 mg/L, or, if tolerated, increases to 0.5 mg daily if hs-CRP is ≥2.0 mg/L. Participants who increase to 0.5 mg daily undergo repeat assessment after another month. If the assigned target remains unmet after one month at 0.5 mg daily, protocol-directed colchicine is stopped while clinical and safety follow-up continues under the original randomized assignment. Doses may be reduced or treatment stopped for adverse reactions; interruptions may occur during acute infection or elective surgery. Follow-up assessments occur at 1, 3, 6, 12, and 18 months, with an additional 2-month assessment for participants whose dose was increased at 1 month. An independent blinded clinical events committee adjudicates events.

Experimental: Standard hs-CRP Target (1.0 to <2.0 mg/L)

Colchicine 0.25 mg orally once daily at initiation, with hs-CRP-guided adjustments to target 1.0 to <2.0 mg/L. At 1 month, reduce to 0.25 mg every other day if hs-CRP <1.0 mg/L; maintain 0.25 mg daily if 1.0 to <2.0 mg/L; or, if tolerated, increase to 0.5 mg daily if ≥2.0 mg/L. If the target remains unmet after one month at 0.5 mg daily, stop protocol-directed colchicine and continue endpoint/safety follow-up. Dose reduction or discontinuation is permitted for adverse reactions.
