thrombolysis therapy

Leiden University Medical Center · Phase 3 active Small molecule ✓ Verified May 2026

thrombolysis therapy is a Thrombolytic agent Small molecule drug developed by Leiden University Medical Center. It is currently in Phase 3 development for Acute myocardial infarction, Acute ischemic stroke, Pulmonary embolism. Also known as: systemic thrombolysis, full-dose systemic thrombolysis, thrombolysis, thrombolytic therapy.

Thrombolysis therapy dissolves blood clots by activating fibrinolytic enzymes to break down fibrin and restore blood flow in occluded vessels.

Thrombolysis therapy involves administering alteplase, a recombinant tissue plasminogen activator, to dissolve blood clots in conditions such as acute ischemic stroke and large vessel occlusion. Alteplase is administered via a 10% IV bolus followed by a 90% 1-hour IV drip at a dose of 0.9mg/kg.

Likelihood of approval
56.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Cardiovascular Phase 3 risk -2.0pp
    Modern cardiovascular outcome trials are large + long; many fail to beat aggressive standard-of-care.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr
MHRA GB 2029–2031 +0.7 yr

Mechanism of action

Thrombolytic agents work by converting plasminogen to plasmin, a serine protease that degrades fibrin—the structural protein in blood clots. This enzymatic fibrinolysis restores perfusion in thrombotic occlusions of coronary, cerebral, or peripheral vessels. The approach is time-sensitive and most effective when administered early after clot formation.
