The FDA Approves Ticagrelor for Primary Prevention in High Risk Patients

The FDA has approved the indication of ticagrelor as primary prevention in high risk CAD patients with no history of MI or stroke. 

La FDA aprueba el ticagrelor en pacientes de alto riesgo como prevención primaria

The lab producing ticagrelor has informed the FDA has based this decision on the THEMIS study, which included nearly 20,000 patients with stable CAD and type 2 diabetes.

This decision has come as a surprise for many, given the delicate balance this study has shown in terms of risk/benefit ratio, let alone the cost of this drug. 

In the THEMIS, ticagrelor significantly reduced the combined end point of major cardiovascular events (cardiovascular death, MI or stroke) compared against placebo (both arms received aspirin). This difference was significant, but in absolute terms event reduction was lower than 1% (7.7% vs 8.5%; p=0.04).

In addition, this event reduction happened at the cost of a two-fold increase in major bleeding (2.2% vs.1.0%; p<0.001) and also intracranial bleeding (0.7% vs. 0.5%; p=0.005).

In fact, when the THEMIS was presented last year at the ESC by Deepak Bhatt (one of the authors) it was said that for stable CAD patients with diabetes and no history of MI or stroke, the risk of bleeding counterbalanced the benefit of ticagrelor.
