A Phase 2a Study to Evaluate the Dose-response, Safety, Tolerability, Efficacy, and Population Pharmacokinetics of Intravenous NTS-521 Infusions in the Early Recovery Treatment From Acute Ischemic Stroke (ACT-IVATE)
A Phase 2a Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel-arm Domain Within the ACT-GLOBAL Trial Platform, to Evaluate the Dose-response, Safety, Tolerability, Efficacy, and Population Pharmacokinetics of Intravenous NTS-521 Infusions in the Early Recovery Treatment From Acute Ischemic Stroke

Gedetailleerde beschrijving
Stroke represents a major global public health crisis, characterized by a paradox: declining age-standardized rates yet a rapidly expanding absolute global burden. According to recent epidemiological analyses from the Global Burden of Disease (GBD) study there were 11.9 million incident strokes worldwide in 2021, corresponding to a global age-standardized incidence rate of 141.5 per 100,000 person-years. Stroke claimed 7.3 million lives (an age-standardized mortality rate of 87.4 per 100,000), making it the third leading cause of mortality worldwide, accounting for 10.7% of all deaths.
The trial's target population for NTS-521 intervention consists of participants undergoing endovascular thrombectomy (EVT), and/or intravenous thrombolysis (IVT), or medical care without reperfusion treatment.
