Integrilin and Ilomedin in Combination in Comparison to Standard Treatment in Severe Pneumonia Patients With Severe Sepsis

This is an investigator sponsored double-blinded, multinational, multi center, randomized (2:1 active:placebo), placebo-controlled, phase IIa trial in severe pneumonia patients with severe sepsis or septic shock, investigating the safety and efficacy of co-administration of Iloprost and escalating doses of Eptifibatide for continuous intravenous infusion in totally 36 patients.
