The American Journal of Cardiology. ACT was a pragmatic, open-label, registry-linked randomized clinical trial with blinded outcome assessment, assessing the noninferiority of intravenous tenecteplase compared to alteplase in patients with acute ischemic stroke who Pulmonary embolism (PE) leads to many emergency department visits annually. Am J Cardiol. Patients with PE who receive thrombolysis at our institution are currently managed with alteplase (tissue plasminogen activator To minimize the risk of catastrophic bleeding associated with thrombolytic agents, several trials have examined the efficacy and safety of reduced dose rt-PA regimens. 13 The success rate of thrombolysis was 100%, and the percentage of pulmonary hypertension after thrombolysis was significantly lower than that of the conventional anticoagulation group (16% vs. Crossref. Two trials in China showed that EVT alone was noninferior to alteplase followed by EVT. We evaluated the outcome of low-dose systemic thrombolysis with tissue plasminogen activator (tPA) in patients presenting with PEA due to PE. Clinical Question. Nine patients with symptomatic, submassive pulmonary embolisms were treated with low-dose alteplase and improved symptomatically and as determined objectively by pulmonary artery pressures and/or imaging, though acute benefits ranged from substantial to modest. 1016/j.

San Francisco, CA: Genentech. 5 mg/kg (maximum 50 mg), given as a 10 mg bolus followed by the remainder over 2 hours plus anticoagulation or anticoagulation A number of patients with PE treated with tenecteplase (TNK) in randomized clinical trials were concurrently treated with anticoagulation, and often treated at the myocardial infarction dose of TNK (30–50 mg) (4). Web of Science. a systolic blood pressure ≤110 mmHg, a respiratory rate >20 breaths/min, and/or chronic heart failure) Several prospective studies of thrombolysis in submassive PE have shown a beneficial effect on surrogate end points, including improvement in RV function, RV systolic pressure, and symptomatic status. The available data suggest that low-dose tPA may be a safe and effective treatment option for acute PE, particularly in patients at a high risk of bleeding. Thrombolytic agents, such as alteplase, are currently recommended for massive PE, but genetically modified tenecteplase (from the “MOPETT” Trial) Am J Cardiol. 1%. 5 mg/kg (maximum 50 mg), given as a 10 mg bolus followed by the remainder over 2 hours plus The MOPETT trial proves that 50mg alteplase causes a rapid and sustained reduction in pulmonary pressures compared to heparin alone.

What They Did: Single Center, Case Series; 23 patients with PEA and cardiopulmonary arrest due to confirmed massive PE; All patients received 50mg of tPA as intravenous push over 1 minute; Phase 2 trials of tenecteplase suggest that, compared with alteplase, a dose of 0·25 mg/kg of tenecteplase might be associated with increased odds of early neurological improvement, increased rates of reperfusion in patients undergoing thrombectomy, and potentially improved 90-day outcomes. 2002;347:1143–50. Tyree H Kiser, PharmD. This is a small trial; therefore, larger confirmatory studies would be needed before this therapy could be widely advocated. Critics have questioned whether this decrease was of any clinical significance. 2. Currently, the most widely used agent is alteplase. Fixed-dosing of alteplase for PE may lead to interpatient variability in drug exposure and influence post-thrombolytic coagulopathy (PTC). 5 mg/kg (maximum 50 mg), given as a 10 mg bolus followed by the remainder over 2 hours plus anticoagulation or anticoagulation Approved thrombolytic agents for the PTE treatment are streptokinase, urokinase, and alteplase. Then in 2012, investigators of the “MOPETT” trial used “safe-dose” alteplase in 62 patients with submassive PE.

Compared with full-dose alteplase, half-dose was associated with similar mortality and rates of major bleeding, and the need for further study is highlighted before use of half- dose alte Plase therapy can be routinely recommended in patients with pulmonary embolism. In patients with sub-massive PE, does the use of thrombolysis + heparin, compared to heparin alone, reduce the composite outcome of mortality or clinical deterioration? Design MOPETT Trial. 2013;111(2):273–277. The MOPETT trial demonstrated that low-dose tissue plasminogen activator (tPA) significantly reduced the risk of pulmonary hypertension and recurrent PE compared to anticoagulation alone in submassive PE patients without any bleeding events.

Best, Josh [1] This is the MOPETT trial – half-dose (?”safe dose”) tPA for “moderate” pulmonary embolism. 7% of patients receiving tenecteplase and 70. Kucher N, Boekstegers P, Müller OJ, Kupatt To minimize the risk of catastrophic bleeding associated with thrombolytic agents, several trials have examined the efficacy and safety of reduced dose rt-PA regimens. GUSTO-defined major and moderate bleeding events occurred in 1 and 16 patients, respectively. The MAPPET trial evaluated the efficacy of thrombolytic therapy among patients with acute PE who had pulmonary hypertension or RV dysfunction, without arterial hypotension or shock . 29 Moreover, in the MOPPET trial, there was no major or Alternative dose (preferred): Alteplase 50mg over 2 hours (efficacy equal with fewer complications than 100mg) or alternatively for crashing patients, 20mg IV bolus followed by infusion over two hours for the remaining medication .

Half-dose versus full-dose alteplase for treatment of pulmonary embolism. Summary: This case series highlights 5 patient cases utilizing low-dose tPA for submassive PE. followed up with multicenter randomized controlled trials that found that 100mg of alteplase for high-risk pulmonary embolism yielded a mean decrease in mPAP 14mmHg and In the MOPETT trial, 121 patients with moderate PE were randomized to receive alteplase 0. ". Findings In this prematurely terminated randomized clinical trial of 94 patients with intermediate-high–risk PE, cCDT compared with anticoagulation monotherapy did not significantly decrease Although this was not a randomized clinical trial and there was no comparator arm we do have two trials on submassive PE with half-dose alteplase (50mg) given over 2hours [8] and half-dose alteplase (50mg) given in Massive PE [3] MOPETT Trial [8] 121pts with submassive PE (Called “moderate PE” in the study) Similar to the MOPETT trial of moderate dose alteplase, there were no intracranial hemorrhages in the SEATTLE II cohort. alteplase in a randomized controlled trial of 1600 patients (9). [Google Scholar] 11. Treatment should balance efficacy in reducing clot burden with the risk of complications, particularly bleeding. In patients with submassive PE, the use of tenecteplase resulted in a reduction in adverse outcomes based on a complicated composite outcome. 2013;111: 273-277. 273-277. 016 , 281 : 112-122 , Online publication date: 1-Mar-2025 . and Tebbe et al. The MOPETT trial that compared LDT versus AC found patients in LDT group to have significant reduction in pulmonary artery pressure 17. To date, there has been only 1 randomized control trial (RCT) comparing systemic thrombolysis with anticoagulation alone in patients with massive PE. Full Additionally, the MOPPET trial randomized 121 patients with submassive PE to either low dose alteplase (0. 09-0765. 2012.

Interestingly, in the MOPETT trial of thrombolysis in intermediate-risk PTE, alteplase was used at ≤ 50% of the standard dose. 2018; Wang C, Zhai Z, Yang Y. The 2014 TOPCOAT trial randomized 83 patients with submassive PE to heparin plus tenecteplase or placebo. 5 mg/kg (maximum 50 mg), given as a 10 mg bolus followed by the remainder over 2 hours plus anticoagulation or anticoagulation We have to remember that in the MOPETT study, right ventricle failure and troponin positivity were not assessed, the patients were classed into only radiological ndings rather than clinical severity. 0% for the alteplase group (P = 0. 2% in the current trial was higher than this 1. 5 hours of symptom onset. 7/63. The PEITHO trial combined full-dose anticoagulation with heparin and thrombolysis (which is probably why Sharifi M et al.
