Filter by:This is a multicenter, randomized, double-blinded, placebo-controlled, dose-escalation trial. The objective of this study is evaluating safety and preliminary efficacy of intravenous exosomes derived from human induced pluripotent stem cell (GD-iExo-003) in acute ischemic stroke.
The purpose of this study is to evaluate the safety and efficacy of urinary kallidinogenase treatment in patients with large artery atherosclerotic acute ischemic stroke.
This is a 50-patient, Phase 2, double-blind, randomized, placebo-controlled, hybrid decentralized study to evaluate the safety and efficacy of daily subcutaneous (SC) injection of TXA127 in post-ischemic stroke patients. Subjects will receive either TXA127 0.5mg/kg or placebo for 12 weeks started 6 to 24 months post ischemic stroke, and they will have a 12 week follow up visit after treatment has ended. The primary efficacy outcome measure is individual patient absolute change from baseline in motor and sensory functions as measured by the Fugl-Meyer Assessment of Upper Extremity (FMA-UE) 12 weeks after start of treatment.
This is a prospective cohort study to investigate the early impact of evolocumab on patients with acute ischemic stroke (AIS) in China. Evolocumab, a proprotein convertase subtilisin/kexin taye 9 inhibitor, can significantly reduce low density lipoprotein cholesterol (LDL-C) levels and has a positive effect on improving cardiovascular events. However, existing studies have focused almost exclusively on the long-term effects of Evolocumab, and the early effects of Evolocumab on AIS patients remains unclear.
The primary purpose of this trial is to evaluate the effects of Human Urinary Kallidinogenase on improvement of neurological outcome, and early cerebral perfusion in acute ischemic stroke.
In the acute posterior circulation strokes, the vertebrobasilar occlusions frequently related to worse outcomes than the anterior ones. However, few studies mentioned the benefit and safety of the emergent stenting in the successful recanalization at these complex occlusions. The investigators investigated whether the improvement of clinical outcome was achieved in postprocedural 3-month.
The primary objective of this study is to evaluate the functional recovery based on Barthel index (BI) and modified Rankin Scale (mRS) while the secondary objectives are to assess the survival and re-admission rate as well as to investigate the inflammatory response in a subclinical study within 1 year of Neuroncell-EX infusion in participants with acute ischemic stroke.
Peripheral arterial disease (PAD) affects more than 200 million people worldwide. Although over 50% are asymptomatic, it accounts for 4% of all amputations. The ischemic limb must be revascularized to help wound healing, reduce the pain of ischemia and preserve the limb's function. So, surgical and percutaneous revascularization choices must be considered in CLI. Classically, CLI revascularization aims to provide at least one patent vessel that delivers in-line flow to the foot. Today, the investigators live in a new era of angioplasty evolving and substituting open vascular surgery, so expanding research on endovascular strategy has been noticed.This confirms the profound impact of angioplasty in vascular surgery as one of the fastest-growing branches of medicine Infrapopliteal artery occlusive disease (IPOD) is a significant cause of critical limb-threatening ischemia (CLTI). The worldwide prevalence of IPOD is between 4.5% and 29%, and most patients live in low-income countries. The angiosomal concept was derived from plastic surgery for the skin flap. This concept delineates the human body into three-dimensional blocks of tissue from the skin to bone and also provides practical application of vascular anatomy for reconstructive surgery. An angiosome is an anatomic unit of tissue consisting of skin, subcutaneous, muscle, and bone fed by a source artery and drained by a specific vein. According to the angiosomal concept, the foot is divided into six distinct angiosomes fed by source arteries, three from the posterior tibial, two from the peroneal, and one from the anterior tibial artery, with functional artery-to-artery connections among muscle, fascia, and skin. Numerous direct inter-arterial connections occur between the foot's main arteries, which provide alternative pathways of blood flow when disruption or compromise affects the arteries that directly feed the angiosome. On the other hand, in patients with CLI, where only one vessel runoff can be established to the foot, direct flow into a patent pedal arch is essential to improve their clinical outcomes. Conventional Endovascular therapy aims to the re-establishment of pulsatile straight-line flow to the lower limb. This results in relieving ischemic pain, healing ulcers, achieving limb salvage, improving quality of life, and potentially prolonging survival. So it became essential to know the differential impact of both concepts on CLI revascularization.
This study is designed to observe the treatment options in real-world clinical practice as well as the safety and efficacy of different treatment strategies.
The purpose of this trial is to evaluate the safety and efficacy of the Drug Eluting Temporary Spur Stent System compared to PTA. The Drug Eluting Temporary Spur Stent System is intended for use as a primary treatment in the infrapopliteal arteries for the treatment of de novo or restenotic lesions.
