Colchicine and Spironolactone in Patients with MI / SYNERGY Stent Registry

The CLEAR SYNERGY trial will study the long term effects of treatments following PCI to treat myocardial infarction. These treatments address both the culprit artery (PCI with SYNERGY stent) as well as the non-culprit arteries (randomization to routine colchicine and spironolactone).

About this study

This is a multicenter, international SYNERGY stent registry that is embedded within a randomized, blinded, double-dummy, 2x2 factorial design trial of colchicine versus placebo and spironolactone versus placebo in patients with myocardial infarction who have undergone primary percutaneous coronary intervention (PCI).

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • a) Patients with STEMI referred for PCI within 12 hours of symptom onset, have a culprit lesion amenable to stenting, and with planned SYNERGY stent implantation for SYNERGY registry

OR

b) Patients with STEMI referred for PCI within 48 hours of symptom onset, not prospectively enrolled in SYNERGY stent registry

OR

c) Patients with diagnosis of Non STEMI with ischemic symptoms and either Hs Troponin > or = 300x ULN or Troponin > or = 200x ULN who have undergone PCI with one of the following:

i. LVEF< or =45% ii. Diabetes iii. Multivessel CAD defined as 50% stenosis in 2nd major epicardial vessel iv. Prior MI v. Age >60 years

  • Able to be enrolled/randomized within 72 hours of index PCI (however patients should be randomized as soon as possible after PCI)
  • Written informed consent

Exclusion criteria

  • Age ≤18 years
  • Pregnancy, breastfeeding, or women of childbearing potential who are not using an effective method of contraception
  • Any medical, geographic, or social factor making study participation impractical or precluding required follow-up
  • Systolic blood pressure <90 mm Hg
  • Active diarrhea
  • Known allergy or contraindication to everolimus, the SYNERGY stent or any of its components
  • Unable to receive dual antiplatelet therapy
  • Any contraindication or known intolerance to colchicine or spironolactone
  • Requirement for colchicine or mineralocorticoid antagonist for another indication
  • History of cirrhosis or current severe hepatic disease

Primary outcomes

  1. Major Adverse Cardiac Events (MACE)

    Time frame: up to 1 year

    Major Adverse Cardiac Events (MACE) for SYNERGY Stent (defined as the composite of death, recurrent target vessel MI, stroke, or ischemia driven target vessel revascularization) compared to performance goal

  2. Composite of cardiovascular death, recurrent myocardial infarction, stroke, or unplanned ischemia driven revascularization

    Time frame: through study completion, an estimated average of 3 years

    The first occurrence of cardiovascular death, recurrent myocardial infarction, stroke, or unplanned ischemia driven revascularization in the colchicine comparison

  3. Total composite events of cardiovascular death or new or worsening heart failure (co-primary 1)

    Time frame: through study completion, an estimated average of 3 years

    Total composite of cardiovascular death or new or worsening heart failure in the spironolactone comparison (co-primary 1)

  4. Composite of cardiovascular death, new or worsening heart failure, recurrent myocardial infarction, or stroke (co-primary 2)

    Time frame: through study completion, an estimated average of 3 years

    The first occurence of cardiovascular death, new or worsening heart failure, recurrent myocardial infarction, or stroke in the spironolactone comparison (co-primary 2)
