Evaluating SP-8203 for treating acute ischemic stroke alongside standard thrombolytic care

A Multi-Center, Randomized, Double-Blind, Parallel, Placebo-Controlled, Phase III Clinical Study to Evaluate Efficacy and Safety of SP-8203 (Otaplimastat) in Patients With Acute Ischemic Stroke Requiring Thrombolytic Therapy as Standard of Care

Phase 3 Interventional Shin Poong Pharmaceutical Co. Ltd. · NCT06660719

This study is testing if adding a new drug called SP-8203 to standard treatment can help people with acute ischemic stroke recover better and improve their brain function.

What this trial studies

This clinical study aims to assess the efficacy and safety of SP-8203 (otaplimastat) when used in combination with standard thrombolytic therapy in patients experiencing acute ischemic stroke. A total of 852 participants will be enrolled in a double-blind, randomized, parallel design, with half receiving SP-8203 and the other half receiving a placebo. Participants will undergo brain imaging tests before and after treatment to evaluate the intervention's impact on infarct volume and neurological recovery. The study will focus on patients with a significant neurologic deficit as measured by the National Institute of Health Stroke Scale (NIHSS).

Who should consider this trial

Good fit: Ideal candidates are adults aged 19 to 85 with a neurologic deficit of 8 or more on the NIHSS who can receive thrombolytic therapy within 4.5 hours of symptom onset.

Not a fit: Patients with recent myocardial infarction, significant arrhythmias, or systemic allergic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve recovery outcomes for patients suffering from acute ischemic stroke.

How similar studies have performed: Other studies have shown promise with neuroprotectants in stroke treatment, but the specific combination of SP-8203 with thrombolytic therapy is novel.
