Retavase (Reteplase) - Summary

 
 



RETAVASE SUMMARY

Retavase® (Reteplase) is a non-glycosylated deletion mutein of tissue plasminogen activator (tPA), containing the kringle 2 and the protease domains of human tPA. Retavase® contains 355 of the 527 amino acids of native tPA (amino acids 1-3 and 176-527). Retavase® is produced by recombinant DNA technology in E. coli. The protein is isolated as inactive inclusion bodies from E. coli, converted into its active form by an in vitro folding process and purified by chromatographic separation.

Retavase® (Reteplase) is indicated for use in the management of acute myocardial infarction (AMI) in adults for the improvement of ventricular function following AMI, the reduction of the incidence of congestive heart failure and the reduction of mortality associated with AMI. Treatment should be initiated as soon as possible after the onset of AMI symptoms (see CLINICAL PHARMACOLOGY).

NEWS HIGHLIGHTS

Published Studies Related to Retavase (Reteplase)

Abciximab combined with half-dose reteplase has beneficial effects on inflammatory myocardial response in patients with myocardial infarction. [2009.03]
In patients with ST-segment elevation myocardial infarction (STEMI), myocardial reperfusion is associated with an inflammatory response leading to adverse effects on further myocardial damage. Therefore, we investigated the effects of the thrombolytic regimen with half-dose reteplase (r-PA) combined with abciximab on different cytokines involved in the local and systemic inflammatory scenario in STEMI patients...

Immediate angioplasty versus standard therapy with rescue angioplasty after thrombolysis in the Combined Abciximab REteplase Stent Study in Acute Myocardial Infarction (CARESS-in-AMI): an open, prospective, randomised, multicentre trial. [2008.02.16]
BACKGROUND: Thrombolysis remains the treatment of choice in ST-segment elevation myocardial infarction (STEMI) when primary percutaneous coronary intervention (PCI) cannot be done within 90 min. However, the best subsequent management of patients after thrombolytic therapy remains unclear. To assess the best management, we randomised patients with STEMI treated by thrombolysis and abciximab at a non-interventional hospital to immediate transfer for PCI, or to standard medical therapy with transfer for rescue angioplasty... INTERPRETATION: Immediate transfer for PCI improves outcome in high-risk patients with STEMI treated at a non-interventional centre with half-dose reteplase and abciximab.

Primary percutaneous coronary intervention of an unprotected left main using mini-crush drug-eluting stents facilitated by intracoronary reteplase. [2011.03.01]
Patients suffering from acute myocardial infarction with involvement of unprotected left main (LM) coronary artery disease represent a very high-risk subgroup. A 37-year-old male patient was admitted with posterolateral acute myocardial infarction and in borderline hemodynamic condition... The patient recovered without complications and had a favorable outcome at mid-term.

Thrombolysis with reteplase for recurrent mechanical heartvalve thrombosis. [2011.02]
Thrombotic occlusion of a prosthetic valve continues to be an uncommon but life threatening complication of mechanical valves. However, recurrent prosthetic valve thrombosis is yet a rare complication... We report the first three cases of recurrent prosthetic mitral valve thrombosis in Pakistan which were treated with Reteplase that resulted in re-establishment of adequate blood flow across the valve with reduction of mean gradient to normal.

Effect of Reteplase and PAI-1 antibodies on postoperative adhesion formation in a laparoscopic mouse model. [2009.05]
BACKGROUND: Postoperative adhesions remain an important clinical problem, accounting for infertility, chronic pain and bowel obstruction. Its prevention is still inadequate and overall poorly understood. The aim of this study was to investigate the effect of Reteplase (a recombinant plasminogen activator, r-PA) and of PAI-1 antibodies upon adhesion formation in a laparoscopic model... CONCLUSIONS: Low-dose i.p. administration of rPA is effective in the prevention of adhesions in a laparoscopic mouse model.

Clinical Trials Related to Retavase (Reteplase)

Pre-hospital Administration of Thrombolytic Therapy With Urgent Culprit Artery Revascularization [Recruiting]
The PATCAR study has been designed to test the hypothesis that the strategy of pre-hospital use of a "clot busting" (thrombolytic) drug followed with emergent heart catheterization including stenting of the problematic coronary artery, will result in a lower mortality and reduced repeat heart attack rates.

Early identifying and treating heart attacks patients prior to the arriving at the hospital, in those patients who qualify for the "clot busting" drugs will lower the size of the heart attack damage. This smaller heart attack will lead to fewer problems with less repeat heart attacks and death in the future.
