Filter by:This is an early phase study to assess how safe and tolerable is the new study drug YQ23 and to compare the effectiveness of YQ23 against normal saline to treat critical limb ischaemia. The study also aims to understand how it affects the body and an optional substudy to assess how the human body takes up, breaks down, and clears the study drug. Eligible patients will be randomised to have a 2:1 chance to receive a single, intravenous, fixed dose of YQ23 or normal saline. Neither the patient nor the study site will know which treatment has been given. On the day of YQ23 administration, patients will be asked to stay in the study site for 3 days for safety observation. After discharge, they will be required to visit the study clinic for 3 times in a year to continue safety monitoring and assessment of treatment effect. Each subject's participation will be about 13 months after signing the informed consent.
The objective is to ensure the pro-active collection of information on quality, safety and performance of FlowOx™ after it is placed on the market. The study will be carried out in a patient population with peripheral artery disease (claudicatio intermittens) to confirm its usefulness and in particular gather information for further improvements of the device related to this patient population. The data collected from the use of the CE-marked FlowOX™ device are change of walking distance, quality of life, and the patient's compliance.
The primary objective of this study is to evaluate the performance of the HemaTrate™ Blood Filtration system in the treatment of critical limb ischemia. The primary endpoint measure is comparing the percentage of patients between the treatment arm and control arm who have freedom from major amputation, arterial intervention below the knee, and death through 12 months.
This is a prospective, nonrandomized, single-arm study using CSI Orbital Atherectomy System in patients with PAD (total occlusions or significant stenosis). Patients will be enrolled if they have claudication and/or critical limb ischemia, and identifiable PAD disease with moderate to severe calcification on Computer Tomography Angiogram (PCA) or peripheral angiogram requiring percutaneous peripheral intervention (PPI).
Chronic non-healing wounds represent a major source of morbidity, disability, and mortality in diabetic patients. Diabetes is the leading cause of non-traumatic limb amputations worldwide. Many patients with ischemic or neuroischemic wounds are not candidate to surgical/endovascular revascularization, owing to anatomical vascular reasons or for the underlying conditions and co-morbidities. Therefore, identification of novel medical treatment strategies to improve wound healing in diabetic patients is a major challenge for clinicians, researchers, and health care systems. Defects in bone marrow (BM)-derive stem and progenitor cells, including EPCs (endothelial progenitor cells), contribute to diabetic complications. Stem cell mobilizing agents have been previously studied as an adjunctive therapy for critical limb ischemia and chronic non-healing wounds in diabetic and non-diabetic patients, as well as for the treatment of diabetic wound infections . Meta-analyses of such studies indicate that stem cell mobilization in these clinical conditions is safe and potentially effective in improving surrogate outcome measures and hard endpoints (such as rates of wound healing and amputation). This study plans to evaluate whether a single injection of Plerixafor improves wound healing in diabetic patients with stage III-IV (neuro)ischemic wounds.
Study to Evaluate the Efficacy and Safety of AMG0001 in Subjects with Critical Limb Ischemia.
A Prospective, Randomized, Single-center Pilot Study of The OxyGenesys(TM) Dissolved Oxygen Dressing to Improve Chronic Wound Healing after REvascularization for Critical Limb Ischemia.
In this randomized clinical trial (RCT) the investigators are trying to find out whether a low-dose therapy with daily short infusions of urokinase using 10 to 21 doses over a maximum of 30 days is capable of prolonging the survival time without major amputation.
Diabetic foot syndrome (DFS) is a disease caused by neurogenic (concerning the nervous system), vascular, mechanic and metabolic factors, which are further complicated by an impairment of the immune system and a corresponding increase in the risk for infections. Results from clinical trials about the efficacy of interventions aimed at reducing the number of patient-relevant end points are of limited comparability due to the heterogenity of patient characteristics. By their very nature, randomized clinical trials (RCT) can only focus on a limited section of the wide range of possible intervention regimes. In clinical practice, however, a number of patients with dfs will never have been part of a clinical trial. Furthermore, there are only very few contemporary registers for this indication from which conclusions with regard to the comparative merits of different therapeutic strategies may be drawn. The register was conceived to find out to which extent RCT patients are representative for the overall patient collective with dfs and critical limb ischemia and to evaluate the therapeutic success of other treatment strategies. An RCT to assess the efficacy of urokinase versus placebo is imbedded in the register.
The purpose of the ABSORB BTK Clinical Investigation is to evaluate the safety and efficacy of the Everolimus Eluting Bioresorbable Vascular Scaffold System (BVS) in subjects with critical limb ischemia (CLI) following percutaneous transluminal angioplasty (PTA) of the tibial arteries.
