AGGRASTAT (tirofiban hydrochloride), a non-peptide antagonist of the platelet glycoprotein (GP) llb/llla receptor, inhibits platelet aggregation.
AGGRASTAT, in combination with heparin, is indicated for the treatment of acute coronary syndrome, including patients who are to be managed medically and those undergoing PTCA or atherectomy. In this setting, AGGRASTAT has been shown to decrease the rate of a combined endpoint of death, new myocardial infarction or refractory ischemia/repeat cardiac procedure (for discussion of trial results and for definition of acute coronary syndrome see CLINICAL PHARMACOLOGY,
AGGRASTAT has been studied in a setting, as described in
Clinical Trials, that included aspirin and heparin.

Safety of Tirofiban in acute Ischemic Stroke: the SaTIS trial. [2011.09]
BACKGROUND AND PURPOSE: Tirofiban is a highly selective, fast-acting nonpeptide glycoprotein IIb/IIIa platelet receptor antagonist with a short half-life time. Glycoprotein IIb/IIIa antagonists are effective for the treatment of acute coronary syndromes proven in large clinical trials. Safety and efficacy in patients with ischemic stroke are uncertain. This was addressed in the Safety of Tirofiban in acute Ischemic Stroke (SaTIS) trial... CONCLUSIONS: We conclude that tirofiban might be safe in acute moderate ischemic stroke even when administered within a large time window after symptom onset and might save lives in the late outcome. Clinical Trial Registration- URL: www.strokecenter.org/trials/. Trial name: SaTIS. Enrollment began before July 1, 2005.
A randomized two-by-two comparison of high-dose bolus tirofiban versus abciximab and unfractionated heparin versus bivalirudin during percutaneous coronary revascularization and stent placement: the tirofiban evaluation of novel dosing versus abciximab with clopidogrel and inhibition of thrombin (TENACITY) study trial. [2011.06.01]
CONCLUSION: With limited assessment, this direct comparison of high-dose bolus tirofiban versus abciximab produced encouraging results and suggests that further study of this tirofiban dose regimen is warranted. The limited assessments comparing heparin and bivalirudin are consistent with prior observations. Copyright (c) 2010 Wiley-Liss, Inc.
Long-term reduction of mortality in the 4-year follow up of tirofiban therapy in elective percutaneous coronary interventions (TOPSTAR) trial. [2011.04]
BACKGROUND: TOPSTAR was a randomized, placebo-controlled trial studying the effects of adding the glycoprotein IIb/IIIa inhibitor tirofiban to conventional treatment with aspirin and clopidogrel in patients undergoing elective percutaneous coronary interventions (PCI). TOPSTAR demonstrated a lower periprocedural troponin release and a reduced 6-month mortality risk following PCI. The present study analyzed the corresponding long-term effects... CONCLUSIONS: The reduced 6-month mortality risk after elective PCI in the TOPSTAR trial persisted after 4 years of follow up. Even in this relatively small study, periprocedural effective platelet inhibition had a sustained impact on long-term mortality risk.
Clinical Trials Related to Aggrastat (Tirofiban)
Pharmacokinetic Evaluation of Tirofiban Using a Single High-Dose Bolus In Subjects With Varying Degrees of Renal Function [Not yet recruiting]
The purpose of this study is to evaluate tirofiban concentration in the blood over a period
of 24 hours after tirofiban administration. Subjects with varying degrees of renal
insufficiency (i. e. kidney function) will be included in the study. Tirofiban is known to be
cleared from the blood by the kidneys and so people with kidney problems clear tirofiban to
a slower extent compared to people without kidney problems. By comparing the tirofiban
concentration profile between subjects with healthy kidney function versus with impaired
kidney function, a tirofiban dosing recommendation for subjects with impaired kidney
function can be made.
This is a non-randomized, single-center, open-label study. A single dose of tirofiban (25
µg/kg administered intravenously over a 3 min period) will be administered to subjects with
normal renal function (>90 mL/min CrCl), moderate (30-59 mL/min CrCl), and severe (<30
mL/min CrCl) renal impairment with non-dialysis-dependent renal insufficiency
Aggrastat Truncated Length Against Standard Therapies in Percutaneous Coronary Intervention [Not yet recruiting]
The purpose of this study is to determine whether the efficacy of tirofiban (a 25mcg/kg i. v.
bolus followed by a 0. 15mcg/kg/min i. v. infusion during a percutaneous coronary intervention
(PCI) plus two hours after the procedure) is more effective than placebo in the setting of
standard therapies (e. g. aspirin, a thienopyridine, and unfractionated heparin or
bivalirudin) among patients undergoing PCI, as assessed by the incidence of adverse cardiac
ischemic events defined as death, myocardial infarction (MI), and urgent target vessel
revascularization (uTVR) within 48 hours following study drug initiation.
A secondary objective of this study is to assess whether tirofiban (a 25mcg/kg i. v. bolus
followed by a 0. 15mcg/kg/min i. v. infusion during a PCI plus two hours after the procedure)
is safe compared to placebo in the setting of standard therapies (e. g. aspirin, a
thienopyridine, and unfractionated heparin or bivalirudin) among patients undergoing PCI, as
assessed by the incidence of non-CABG-related TIMI major bleeding within 48 hours following
study drug initiation.
Patient enrollment is pending.
Safety of High-Dose Tirofiban During Coronary Angioplasty [Recruiting]
This single-centre study is intended to retrospectively check the safety of high-dose bolus
of tirofiban in patients who underwent percutaneous angioplasty.
FATA: Randomized Study on Facilitated Angioplasty With Tirofiban or Abciximab [Completed]
The elective("standard of care") treatment of ST - elevation acute myocardial infarction
(STEMI) currently consists of primary angioplasty with stent implantation during
administration of Abciximab, a inhibitor of GP IIb/IIIa platelet receptor.
Tirofiban is another potent inhibitor of GP IIb/IIIa platelet receptor with an efficacy on
platelet aggregation inhibition equal to or greater than Abciximab if a high dose bolus is
used, i. e. 25 microg/kg, (platelet aggregation inhibition > 90% 15 minutes after infusion).
It can therefore be hypothesized that this drug can improve the results of primary
angioplasty to the same extent as Abciximab.
The aim of this study is to compare the efficacy, in terms of myocardial reperfusion indices,
of Abciximab and high dose of Tirofiban in primary angioplasty for STEMI, both in the case of
treatment before transfer and of treatment in the catheterization laboratory during the
The reference hypothesis for the study objective is the equivalence or the non-inferiority of
Tirofiban with respect to Abciximab.
Multicentre 2x2 Factorial Randomised Study Comparing Tirofiban Versus Abciximab and SES Versus BMS in AMI [Active, not recruiting]

abciximab+BMS is the possible gold standard treatment for ST-segment elevation myocardial
infarction in terms of efficacy and cost-efficacy.
