Exploring the Effect of Lactate Administration After Ischemic Stroke on

Status Recruiting

Clinical Trial Summary

In this exploratory randomized double blind placebo controled trial, lactate solution or placebo will be administered to acute ischemic stroke patients selected for endovascular treatment (EVT) without intravenous thrombolysis. The treatment will be administered within one hour after EVT. Primary outcome measures will be lactate and metabolite concentrations in the ischemic lesion, in the penumbra and contralaterally, evaluated by magnetic resonance spectroscopy(MRS). Secondary outcome measures will be evolution of the ischemic penumbra, clinical outcome at 3 months.The trial will end when 10 patients per group have completed the study.

Clinical Trial Description

This is an exploratory randomized double blind placebo controled trial on acute ischemic stroke patients. Lactate solution or placebo will be administered to acute ischemic stroke patients selected for endovascular treatment (EVT) without intravenous thrombolysis. Magnetic resonance spectroscopy will be performed before EVT to measure metabolite concentrations in the ischemic core, penumbra and in the contralateral hemisphere. The treatment will be administered within one hour after EVT. As soon as the patient is stabilized, she/he will undergo an additional magnetic resonance imaging (MRI) with magnetic resonance spectroscopy (MRS). MRS will also be performed during the control MRI after 24 hours. Neurological deficits will be evaluated on admission, at 24 hours using the National Institute of Health Stroke Scale (NIHSS), and at 3 months, with both NIHSS and the modified Rankin scale. Primary outcome measures will be lactate and metabolite concentrations changes in the ischemic lesion, in the penumbra and the contralateral side, evaluated by magnetic resonance spectroscopy after intervention compared to baseline MRS values. Secondary outcome measures will be evolution of the ischemic penumbra and clinical outcome at 3 months. The trial will end when 10 patients per group have completed the study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
