NCT00039832 ↗	ReoPro and Retavase to Restore Brain Blood Flow After Stroke	Completed	National Institute of Neurological Disorders and Stroke (NINDS)	Phase 2	2002-03-01	This study will evaluate the safety and effectiveness of two types of blood thinners, abciximab (ReoPro) and reteplase (Retavase) for restoring normal brain blood flow after ischemic stroke (stroke resulting from a blood clot in the brain). The only therapy approved by the Food and Drug Administration to treat ischemic stroke is the clot buster drug rt-PA. This treatment, however, is effective only if begun within 3 hours of onset of the stroke and most patients do not get to the hospital early enough to benefit from it. There is thus a pressing need to develop effective stroke treatments that can be initiated more than 3 hours after onset. Patients between 18 and 80 years of age who have experienced a mild or moderate acute stroke between 3 and 24 hours before starting study drugs may be eligible for this study. Candidates will be screened with a physical examination, blood tests and a magnetic resonance imaging (MRI) scan (if an MRI was not done during the stroke evaluation). All participants will receive ReoPro. Some will also receive Retavase, which may boost the effectiveness of ReoPro. Retavase is administered in a single dose through a needle in the vein over 2 minutes. ReoPro is infused into the vein over 12 hours. Patients will be monitored with physical examinations, blood tests, computed tomography (CT) scans, and three or four MRI scans of the brain to evaluate both the response to treatment and side effects of the drugs. An MRI scan will be done 24 hours, 5 days and 30 days after starting the study medication, and possibly during screening for this study. CT involves the use of specialized x-rays to obtain images of the brain. The patient lies still in the scanner for a short time while the X-ray images are formed. MRI uses a strong magnetic field and radio waves to demonstrate structural and chemical changes in tissue. MRI is more sensitive than x-ray in evaluating acute stroke. The patient lies on a table in a metal cylinder (the scanner) while the pictures are being taken. During part of the MRI, a medicine called gadolinium contrast is injected in a vein. This medicine brightens the images, creating better pictures of the blood flow.
NCT00046293 ↗	ReoPro and Retavase to Treat Acute Stroke	Completed	National Institute of Neurological Disorders and Stroke (NINDS)	Phase 2	2002-09-24	This study will determine the dose of Retavase that can safely be combined with ReoPro in treating acute ischemic stroke (stroke resulting from a blood clot in the brain). ReoPro and Retavase are currently approved by the Food and Drug Administration to treat heart problems caused by blockage of heart arteries. The only therapy approved by the Food and Drug Administration to treat ischemic stroke is the clot buster drug rt-PA. This treatment is effective only if begun within 3 hours of onset of the stroke, however, and most patients do not get to the hospital early enough to benefit from it. Patients between 18 and 80 years of age who have had a mild or moderate acute stroke between 3 and 24 hours before starting study drugs may be eligible for this study. Candidates will be screened with a medical history and physical examination, blood tests, rating of neurological deficits such as cognition deficits or problems walking that resulted from the stroke, and a computed tomography (CT) scan of the head. CT involves the use of specialized X-rays to obtain images of the brain. The patient lies on a table that is moved into a cylindrical machine (the scanner) for the imaging study, which usually takes about 5 to 10 minutes. All participants will receive 0.25 mg/kg of ReoPro (maximum dose of 30 mg). The drug is infused into the vein over 12 hours. Some patients will also receive one of four doses of Retavase, which may boost the effectiveness of ReoPro in opening the blocked blood vessel. Retavase is given through a needle in the vein over 2 minutes. Patients will be monitored daily until discharge from the hospital, or until day 5, whichever is earlier. Assessments will include physical examinations, blood tests to examine factors involved in blood clotting, and CT scans to evaluate both the response to treatment and drug side effects. They will return for a follow-up examination and CT scan 30 days after treatment. ...
NCT05900674 ↗	Endovascular Stroke Treatment And Reteplase Protocol	Not yet recruiting	Zeenat Qureshi Stroke Institute	Phase 2	2023-07-01	The proposed study is a multicenter, prospective, randomized, open-label, blinded-endpoint trial involving patients with ischemic stroke who are candidates for receiving intravenous (IV) thrombolysis within 4.5 hours after stroke onset. The study aims to test the hypothesis that anterior circulation ischemic stroke patients, selected with "dual target" vessel occlusion within 4.5 hours of onset, will have improved reperfusion and early neurological improvement when treated with intra-arterial clot retrieval after IV reteplase, compared to IV alteplase. Patients will be randomized into one of three treatment arms: local institutional IV thrombolysis, IV reteplase (9 U bolus), or IV reteplase (9 U bolus + 9 U bolus). The study will assess the primary angiographic endpoint of partial or complete recanalization following administration of thrombolytics, as well as the time of recanalization and the time from symptom onset to recanalization. Additional outcome measures include early neurological improvement, assessed by a ≥4-point improvement in National Institutes of Health Stroke Scale (NIHSS) score in the first 24 hours compared to baseline. The trial will be conducted in three groups based on the site of baseline arterial occlusion: internal carotid artery (ICA), proximal middle cerebral artery (MCA - M1), or distal middle cerebral artery (MCA - M2). The study aims to evaluate third-generation thrombolytic - RETAVASE® (reteplase) and compare it to IV alteplase, in acute ischemic stroke patients.

Clinical Trials Update, Market Analysis, and Projection for RETAVASE (Retavase)

Last updated: January 29, 2026

Summary

RETAVASE (reteplase) is an approved thrombolytic agent indicated for acute myocardial infarction (AMI). This analysis provides an in-depth update on ongoing clinical trials, evaluates current market dynamics, and projects future market trends. As of 2023, RETAVASE faces evolving challenges due to competition from newer thrombolytics, shifting clinical guidelines favoring percutaneous coronary intervention (PCI), and demographic changes influencing demand.

---

What is RETAVASE (reteplase)?

RETAVASE is a recombinant plasminogen activator (rt-PA) developed for rapid clot dissolution in acute MI. Approved by the U.S. Food and Drug Administration (FDA) in 1996, it is administered via intravenous infusion, typically within 12 hours of symptom onset. Its mechanism involves catalyzing plasminogen to plasmin, leading to clot breakdown.

Conclusion and Recommendations

RETAVASE continues to serve a niche role in thrombolytic therapy, particularly in resource-limited settings and rural hospitals. However, its market share diminishes due to safety concerns, competition from newer agents, and clinical paradigm shifts favoring PCI.

• Future growth depends on demonstrating superior safety profiles or expanded indications backed by clinical trials.
• Strategic collaboration with health authorities and investment into new formulations or delivery methods could sustain relevance.
• Focused efforts in emerging markets and specialized applications will be critical for market retention.
