Aggrenox®

PRoFESS® - Results

Please note: Aggrenox® did not meet the predefined statistical non-inferiority margin versus clopidogrel. Both regimens show comparable efficacy.

Primary outcome

First recurrence of stroke was confirmed in 1,814 patients.

In 916 recipients (9.0%) treated with extended-release dipyridamole plus ASA and 898 recipients (8.8%) treated with clopidogrel, a first recurrent stroke occurred (hazard ratio, 1.01; 95% CI, 0.92 to 1.11).

The results for the primary outcome had a hazard ratio very close to 1.00 (representing equivalence). However, the upper limit of the confidence interval extended beyond the non-inferiority margin of 1.075.

Time Until Recurrent Stroke

Primary outcome: stroke recurrence slide

* Covariates in Cox model are age, baseline ACE-inhibitor use, modified Rankin, and baseline diabetes status.
