Triple Antiplatelets for Reducing Dependency After Ischaemic Stroke

Summary

The risk of recurrence is greatest immediately after stroke or Transient Ischaemic Attack (TIA). Existing prevention strategies (antithrombotic, lipid/blood pressure lowering, endarterectomy) reduce, not abolish, further events. Dual antiplatelet therapy - aspirin \& clopidogrel (AC) for IHD, aspirin \& dipyridamole (AD) for stroke, is superior to aspirin monotherapy. The investigators hypothesise that triple antiplatelet therapy (ACD) will be superior to AD in patients at high-risk of recurrence, providing bleeding does not become excessive.

Design: TARDIS is a multicentre, parallel-group, prospective, randomised, open-label, blinded-endpoint, controlled trial. In the start-up phase, the investigators will assess over 3 years the safety, tolerability and feasibility of intensive therapy (ACD) versus guideline therapy (AD) given for 1 month in 750 patients with acute stroke/TIA. The main phase will then assess the safety and efficacy of ACD in up to 3500 patients. The primary outcome is ordinal stroke (fatal/severe non-fatal/mild/TIA/none) at 90 days. Secondary outcomes include death, MI, vascular events, function, bleeding, serious adverse events; sub-studies will assess cerebral emboli and platelet function.

DRUG

Aspirin, Dipyradimole, Clopidogrel

Participants in the intensive antiplatelet group will receive Asp+Dip+Clop triple therapy for 28-30 days (to cover the period of maximum risk of recurrence) along with standard 'best care' (including lifestyle advice, BP and lipid lowering). Clop will be given as a loading dose of 300 mg,12 then 75 mg daily, Asp as a loading dose of 300 mg,22 then 75 mg daily, and Dip modified release 200 mg twice daily 9 for 28-30 days.
