Effient (Prasugrel Hydrochloride) - Summary

 
 



WARNING: BLEEDING RISK

Effient can cause significant, sometimes fatal, bleeding [see Warnings and Precautions (5.1 and 5.2) and Adverse Reactions ].

Do not use Effient in patients with active pathological bleeding or a history of transient ischemic attack or stroke [see Contraindications (4.1 and 4.2)].

In patients ≥ 75 years of age, Effient is generally not recommended, because of the increased risk of fatal and intracranial bleeding and uncertain benefit, except in high-risk situations (patients with diabetes or a history of prior MI) where its effect appears to be greater and its use may be considered [see Use in Specific Populations ].

Do not start Effient in patients likely to undergo urgent coronary artery bypass graft surgery (CABG). When possible, discontinue Effient at least 7 days prior to any surgery.

Additional risk factors for bleeding include:

  • body weight < 60 kg
  • propensity to bleed
  • concomitant use of medications that increase the risk of bleeding ( e.g. , warfarin, heparin, fibrinolytic therapy, chronic use of non-steroidal anti-inflammatory drugs [NSAIDS])

Suspect bleeding in any patient who is hypotensive and has recently undergone coronary angiography, percutaneous coronary intervention (PCI), CABG, or other surgical procedures in the setting of Effient.

If possible, manage bleeding without discontinuing Effient. Discontinuing Effient, particularly in the first few weeks after acute coronary syndrome, increases the risk of subsequent cardiovascular events [see Warnings and Precautions].

 

EFFIENT SUMMARY

WARNING: BLEEDING RISK

Effient contains prasugrel, a thienopyridine class inhibitor of platelet activation and aggregation mediated by the P2Y12 ADP receptor.

Effient™ is indicated to reduce the rate of thrombotic cardiovascular (CV) events (including stent thrombosis) in patients with acute coronary syndrome (ACS) who are to be managed with percutaneous coronary intervention (PCI) as follows:

  • Patients with unstable angina (UA) or non-ST-elevation myocardial infarction (NSTEMI).
  • Patients with ST-elevation myocardial infarction (STEMI) when managed with primary or delayed PCI.

NEWS HIGHLIGHTS

Published Studies Related to Effient (Prasugrel)

A comparative evaluation of prasugrel and clopidogrel in patients with acute coronary syndrome undergoing percutaneous coronary intervention. [2013]
patients were also assessed for safety of the drugs... CONCLUSION: This study suggests that prasugrel is more effective than clopidogrel

Concomitant administration of clopidogrel with statins or calcium-channel blockers: insights from the TRITON-TIMI 38 (trial to assess improvement in therapeutic outcomes by optimizing platelet inhibition with prasugrel-thrombolysis in myocardial infarction 38). [2013]
blockers (CCBs) may attenuate the pharmacodynamic effects of clopidogrel... CONCLUSIONS: In patients with ACS undergoing PCI, the use of statins or CCBs was

Gastrointestinal adverse events after dual antiplatelet therapy: clopidogrel is safer than ticagrelor, but prasugrel data are lacking or inconclusive. [2013]
Current guidelines offer a choice of P2Y12 receptor antagonist among clopidogrel, prasugrel or ticagrelor on top of aspirin (ASA) for dual antiplatelet therapy (DAPT) in patients after acute coronary syndromes (ACS). However, the comparative risks of gastrointestinal (GI) adverse events during DAPT are not clear...

Effects of prasugrel on platelet inhibition during systemic endotoxaemia: a randomized controlled trial. [2012]
P2Y(12) receptor antagonists have become a mainstay for the treatment of CVD (cardiovascular diseases). However, they have rarely been evaluated under pathophysiological conditions apart from arterial diseases... However, vWF release may reduce prasugrel's effects under high-shear conditions.

Efficacy and safety of intensive antiplatelet therapy with prasugrel from TRITON-TIMI 38 in a core clinical cohort defined by worldwide regulatory agencies. [2011.10.01]
TRITON-TIMI 38 showed that in patients with acute coronary syndrome undergoing percutaneous coronary intervention prasugrel decreased ischemic events compared to standard clopidogrel, but with more bleeding. The United States Food and Drug Administration and the European Medicines Agency approved prasugrel but provided contraindications in patients with previous stroke or transient ischemic attack and recommended limited use or reduced dose in patients >/=75 years old and weighing <60 kg...

Clinical Trials Related to Effient (Prasugrel)

An Assessment of Prasugrel on Healthy Adults and Sickle Cell Adults [Recruiting]
The purpose of this study is to measure the exposure to prasugrel's active metabolite and the pharmacodynamic effects of prasugrel treatment in people with Sickle Cell Disease (SCD).

Clopidogrel to Prasugrel in Acute Coronary Syndrome (ACS) Patients [Recruiting]
This study will evaluate the use of a prasugrel 60 mg loading dose (LD) administered during percutaneous coronary intervention (PCI) with and without a prior LD of clopidogrel on platelet inhibition in patients presenting with ACS. Platelet inhibition following a prasugrel LD in clopidogrel pretreated patients' will be determined in a time-dependent manner for two different prasugrel loading doses (30 mg and 60 mg). Understanding the effects of this combination on platelet inhibition will provide guidance to physicians on the use of prasugrel in patients who have already been pretreated with clopidogrel.

A Study of Prasugrel in Pediatric Participants With Sickle Cell Disease [Not yet recruiting]
The purpose of this study is to determine the correct prasugrel dosage to be given to children with sickle cell disease (SCD).

Pharmacodynamic Evaluation of Switching From Ticagrelor to Prasugrel in Subjects With Stable Coronary Artery Disease [Recruiting]
This is a Phase 4, multicenter, open-label (blinded Pharmacodynamic PD results), randomized, 3-arm, parallel-design study of subjects with stable Coronary Artery Disease CAD. This study will compare the PD effect of prasugrel 10 mg QD (once-daily) maintenance dose with ticagrelor 90 mg BID (twice daily) maintenance dose in subjects with stable CAD who have previously received ticagrelor loading does (LD) and maintenance dose (MD)..

Therapy With High Clopidogrel Dose or Prasugrel Standard Dose Reduces the Platelet Reactivity in Patients With Genotype Variation RESET Trial [Recruiting]
Dual antiplatelet therapy with aspirin and Clopidogrel for at least one year is essential in patients following an acute coronary syndrome (ACS) or percutaneous coronary intervention (PCI) with drug eluting stent(s. Interindividual variability in platelet response to clopidogrel has been reported, with several mechanisms being implicated for high post-clopidogrel treatment PR. High on-treatment platelet reactivity (HTPR) is associated with an increased risk of adverse events after PCI. Studies in patients on chronic clopidogrel treatment are scarce, mainly in diabetic patients where HTPR is frequently present and independently predictive of adverse events. Optimization of platelet inhibition in patients with HTPR by increasing clopidogrel or alternatively, by more potent P2Y12 inhibitors is a controversial issue, mostly studied in post PCI patients, while no data exist, to the best of the investigators knowledge, in stable patients on chronic clopidogrel treatment. Therefore all HTPR patients, that will accept to participate, will be enrolled will randomize (Day 0) in a 1: 1 ratio to either clopidogrel 150 mg a day, or prasugrel 10 mg a day, until Day 14 post randomization. A 14 ± 2 day visit will be performed for PR measurement and safety evaluation, with the blood sample being will be obtained 16-18 hours after the last study-drug dose, will follow by crossover directly to the alternate therapy for an additional 14 days without an intervening washout period. At Day 28 ± 2 patients will return for the clinical and laboratory assessment as did on Day 14 visit.
