The Feasibility and Safety of RK-4 Injection Bypassing Blood-brain Barrier in the Treatment of Acute Large Hemispheric Infarction Using Intracalvariosseous Injection Device

A pilot study confirmed the feasibility and safety of neuroprotectant RK-4 intracalvariosseous(ICO) injection in patients with malignant middle cerebral artery infarction (mMCAI), showing a trend in improving 90-day functional scores compared to conventional treatment. The aim of this trial is to investigate the feasibility and safety of neuroprotective agent RK-4 injection using intracalvariosseous injection device in patients with acute large hemispheric infarction (LHI) who has contraindications of reperfusion therapy or have got poor reperfusion therapy outcomes.

Intracalvariosseous Plus Intravenous Antibiotics for Moderate-to-Severe Bacterial Meningitis

Multiple preclinical and clinical studies, including the investigators' published work and the ongoing SOLUTION series, have consistently demonstrated that intracalvariosseous (ICO) injection can markedly increase drug exposure within the central nervous system with acceptable safety. This trial is designed to further evaluate the efficacy and safety of antibiotic delivery via the ICO route in the treatment of bacterial meningitis, particularly in patients with moderate-to-severe disease who have shown an inadequate response to standard therapy.

ALA-enriched Nutrition for Prevention of Cognitive Decline in APOE4 Older Adults

This randomized, double-blind, placebo-controlled pilot trial will evaluate the effects of alpha-linolenic acid (ALA) supplementation on cognitive function, blood-brain barrier integrity, and brain vascular health in older adults with mild cognitive impairment and APOE4 genotype. By targeting the endogenous synthesis of docosahexaenoic acid (DHA) through ALA supplementation, the investigators aim to overcome the limitations of direct DHA supplementation, particularly in APOE4 carriers who exhibit low brain DHA levels and impaired blood-brain barrier function. This innovative approach offers a safe, cost-effective, and easily implementable therapeutic strategy for older adults at high risk for Alzheimer's dementia, especially APOE4 carriers, addressing a critical need given the limited cognitive benefits and significant adverse events of current amyloid-clearing drugs in this population.

The Efficacy and Safety of Y-3 Intracalvariosseous Injection Versus Intravenous Injection in the Treatment of Acute Large Hemispheric Infarction

A pilot study confirmed the feasibility and safety of neuroprotectant Y-3 intracalvariosseous(ICO) injection in patients with malignant middle cerebral artery infarction (mMCAI), showing a trend in improving 90-day functional scores compared to conventional treatment. The aim of this trial is to further investigate the efficacy and safety of ICO injection of Y-3 compared to intravenous injection in patients with acute large hemispheric infarction(LHI) who has contraindications of reperfusion therapy or have got poor reperfusion therapy outcomes.
