Remote Ischemic Conditioning for Acute Moderate Ischemic Stroke (RICAMIS): a Prospective, Random, Open Label, Blinded End Point, Multi-center Study

The current treatment based on evidence-based medicine for acute ischemic stroke mainly includes reperfusion (intravenous thrombolysis, mechanical thrombolysis), anti-platelet and stroke units. About 1/3 patients can obtain good prognosis through intravenous thrombolysis. Good prognosis can be gotten from about 50 percent of patients with big artery disease by mechanical embolization. However, only a small proportion of the population can be treated with restoration perfusion in the time window. The main purpose of antiplatelet therapy is to prevent the recurrence and progression of stroke, and stroke unit is a kind of management mode. How to improve the neurological function of patients has been a hot and difficult problem in clinical practice.

A large number of basic and clinical studies have proved that remote ischemic conditioning (RIC) has protective effect on ischemic stroke. Hahn et al showed that RIC could play a neuroprotective role in cerebral ischemia-reperfusion injury in MCAO model. Other studies have also confirmed that preconditioning RIC has a neuroprotective effect on cerebral ischemia in animal models. One open label study by Hougaard et al shows that RIC can improve the NIHSS score in acute ischemic stroke patients. One recent study found that 300 consecutive days RIC therapy for the patients with symptomatic intracranial atherosclerotic stenosis significantly reduced the recurrence rate of stroke, improved the mRS score and recovered the blood flow in the lesion site. Furthermore, several studies have also shown that RIC can not only improve the neurological function of patients with cerebral infarction after intravenous thrombolysis and mechanical thrombolysis, but also protect the secondary brain injury after carotid stenting. These results suggest that RIC has a neuroprotective effect on ischemic stroke and deserves further study.

Based on the above discussion, this study aims to explore the efficacy and safety of RIC in the treatment of acute moderate ischemic stroke.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
